The present disclosure relates generally to communications, and more particularly to communication methods and related devices and nodes supporting wireless communications.
In Rel-10, Carrier Aggregation (CA) was introduced in long term evolution (LTE) to enable the user equipment (UE) to transmit/receive information via multiple cells (sometimes called Secondary Cells—SCell(s)) from multiple carrier frequencies, to benefit of the existing of non-contiguous and contiguous carriers. In CA terminology, the Primary Cell (PCell) is the cell towards which the UE established the radio resource control (RRC) connection or did handover to. In CA, cells are aggregated on medium access control (MAC)-level as shown in
SCells can be “added” (a.k.a. “configured”) for the UE using RRC signaling (e.g., RRCConnectionReconfiguration), which takes in the order of 100s of milliseconds. A cell which is configured for the UE becomes a “serving cell” for this UE. An SCell may also be associated to an SCell state. When configured/added via RRC, an SCell starts in deactivated state. In LTE Rel-15, the eNB (EUTRAN (evolved universal mobile telecommunications system terrestrial radio access) base station) can indicate to activate-upon-configuration, or change the state, at least in RRCReconfiguration, as shown below:
In LTE rel-15, a new intermediate state (i.e., dormant state) between the deactivated and active state has been introduced for enhanced uplink (UL) operation. A MAC Control Element (MAC CE) can be used to change the SCell state between the three states as shown, for example, in
The MAC level SCell activation takes in the order of 20-30 ms. The transitions between Configured and Deactivated are handled by RRC. The transitions between Deactivated, Activated, and Dormant states are handled by MAC. The Dormant state is available in LTE but not yet in new radio (NR). The action of moving to Dormant is called Hybernation.
Once the network understands the need to configure and/or activate CA, the question is which cells to initially configure and/or activate, if they are configured, and/or whether a cell/carrier is good enough in terms of radio quality/coverage (e.g., reference signal received power (RSRP) and reference signal received quality (RSRQ)). To understand the conditions on SCell(s) or potential SCell(s) in a given available carrier the network may configure the UE to perform radio resource management (RRM) measurements.
Typically, the network may be assisted by RRM measurements to be reported by a UE. The network may configure the UE with measurement IDs associated to reportConfig with event A1 (Serving becomes better than threshold) in case this is a configured SCell, or A4 (Neighbor becomes better than threshold) for carriers without a configured SCell as shown in
With the later introduction of Dual Connectivity in Rel-12, it became possible to add what is called SCG (Secondary Cell Group) configuration to the UE. The main benefit is that the UE could in principle add a cell from another eNodeB. Protocol wise, that would require different MAC entities, one for each cell group. The UE will have two cell groups, one associated to the PCell (master node) and another associated to a PScell (of the secondary eNodeB), where each group may possibly have their own associated SCells.
5G (5th generation) in 3GPP (3rd generation partnership project) introduces both a new core network (5GC) and a new radio (NR) access network. The core network, 5GC, will however, also support other radio access technologies (RATs) than NR. It has been agreed that long term evolution (LTE) (or evolved-universal terrestrial radio access (E-UTRA)) should also be connected to 5GC. LTE base stations (eNBs) that are connected to 5GC is called ng-eNB and is part of NG-RAN which also consist of NR base stations called gNBs.
There are different ways to deploy 5G network with or without interworking with LTE (also referred to as E-UTRA) and evolved packet core (EPC), as depicted in
With introduction of 5GC, other options are also valid. As mentioned above, option 2 supports stand-alone NR deployment where gNB is connected to 5GC. Similarly, LTE can also be connected to 5GC using option 5 (also known as enhanced LTE (eLTE), E-UTRA/5GC, or LTE/5GC and the node can be referred to as an ng-eNB). In these cases, both NR and LTE are seen as part of the NG-RAN (and both the ng-eNB and the gNB can be referred to as NG-RAN nodes). It is worth noting that, Option 4 and option 7 are other variants of dual connectivity between LTE and NR that have been standardized as part of NG-RAN connected to 5GC, denoted by MR-DC (Multi-Radio Dual Connectivity). Under the MR-DC umbrella, we have:
As migration for these options may differ from different operators, it is possible to have deployments with multiple options in parallel in the same network e.g. there could be eNB base station supporting option 3, 5 and 7 in the same network as NR base station supporting 2 and 4. In combination with dual connectivity solutions between LTE and NR it is also possible to support CA (Carrier Aggregation) in each cell group (i.e., master cell group (MCG) and secondary cell group (SCG)) and dual connectivity between nodes on same RAT (e.g. NR-NR DC). For the LTE cells, a consequence of these different deployments is the co-existence of LTE cells associated to eNBs connected to EPC, 5GC or both EPC/5GC.
As the use case of UEs with burst traffic constantly being suspended and resuming in the same cell is quite typical, 3GPP has standardized a solution in LTE and NR to enable the UE to assist the network with measurements performed while the UE is in RRC_IDLE or RRC_INACTIVE so that the network could speed up the setup of carrier aggregation or dual connectivity. That solution in described below.
In 3GPP Rel-16 it is possible to configure a UE either in LTE or in NR to report so called early measurements upon the transition from idle or inactive to connected state. These measurements are performed by the UE in idle or inactive state according to a configuration provided by the source cell. The UE then reports these measurement results to the network during or immediately after entering RRC_CONNECTED state. In this way, the network gets the relevant measurement information in order to determine whether the UE is in coverage for CA or DC operation and can quickly setup CA and/or other forms of DC (e.g., EN-DC, MR-DC, etc.) without the need to first provide a measurement configuration (measConfig) in RRC_CONNECTED, as shown in previous sections, and wait for hundreds of milliseconds until first samples are collected, monitored and then the first reports are triggered and transmitted to the network.
This is also described in 3GPP TS 38.300 v16.4.0:
In 3GPP TS 38.331, early measurement results for NR cells are reported in MeasResultIdleNR-r16, which contains a single entity of serving cell measurements (for the PCell) and an optional list of measurement results for neighbouring NR frequencies/cells (for CA and/or DC). For example, an example illustrating an optional list of measurement results for neighboring NR frequencies/cells described in 38.331 v16.3.1, 6.3.2 is shown below:
The early measurement configuration for a neighbouring NR frequency (in MeasIdleCarrierNR-r16) includes, among others, the measurement quantities (reportQuantities) as well as the beam level measurements/reports (BeamMeasConfigIdle-NR-r16) to be applied for that frequency. These parameters can thus be configured individually per frequency. Example parameters configured individually per frequency described in 38.331 v16.3.1, 6.3.2 as shown below:
The procedure in 38.331, 5.7.8.2a however includes that the serving cell measurements are derived and stored once for each neighboring NR frequency for which the UE performs (and stores) measurements. This is not the intended behavior and it would mean that the serving cell measurements then (for each frequency) are derived and stored according to the configured reportQuantities for that specific frequency.
For example, 38.331 v16.3.1, 5.7.8.2a describes:
As seen in the procedural text above from 38.331 v16.3.1, 5.7.8.2a, the UE will report beam level results for each neighboring NR frequency for which the UE performs early measurements and for which beamMeasConfigIdle is included. The UE then includes a list of up to maxNrofRS-IndexesToReport SS/PBCH block indexes in order of decreasing beam sorting. The sorting is done based on the value of reportQuantityRS-Indexes, whereby the beam level results are sorted either by RSRQ, if set to rsrq, or by RSRP, if set to rsrp or both. If includeBeamMeasurements in the beam level configuration is set to true, the UE includes beam measurement results according to the indicated reportQuantityRS-Indexes, i.e., for RSRP, RSRQ or both, in the early measurement results.
A problem is that for the early measurements that are performed by a UE that is in RRC_IDLE or RRC_INACTIVE, and which then are reported to the network when the UE transitions to (or has transitioned to) RRC_CONNECTED in NR, there is no configuration for how to derive and report beam level information for the serving cell. In the early measurement configuration, there is a beam level configuration per neighbouring NR frequency, in the corresponding beamMeasConfigIdle-r16, which includes what measurement quantities to use for the beam measurements, a maximum number of beams to report and an indication whether to include beam measurement results according to the configured measurement quantities. Since there is no corresponding configuration for beam level measurements and reporting for the serving cell it is however ambiguous whether the UE should report beam level measurements at all for the serving cell and, in that case, how they should be reported.
It is thus not clear for the UE whether it should derive and report any measurements on beam level for the serving cell. If the UE anyway decides to do so it is not clear what configuration to use for the corresponding beam level report. This may, for example, lead to a situation in which the UE does not provide any beam level report for the serving cell in the early measurement report even though the network would need it. The information would then be missing for the network, which could negatively impact the usefulness of the early measurement report.
This may also lead to a situation in which the UE does provide a beam level report for the serving cell in the early measurement report, but the network does not know what configuration it is based on, e.g., what measurement quantity that the UE has used. The network might then misinterpret the received measurement information, which may lead to faulty assumptions and decisions. Further, in some situations, the UE does provide a beam level report for the serving cell in the early measurement report even though the network does not need it. The UE would then transmit measurement information to the network in vain, which would lead to unnecessary utilization of UL resources (and power consumption).
According to some embodiments, a method of operating a communication device in a communication network includes receiving, while operating in an idle state, a connected state, or an inactive state, an early measurement configuration to perform an early measurement for reporting to the communication network, wherein the early measurement configuration includes a configuration to perform a beam level measurement for a serving cell. The method includes performing the early measurement including the beam level measurement for the serving cell while operating in the idle state or the inactive state. The method includes reporting an early measurement result including the beam level measurement for the serving cell to the communication network upon the communication device transitioning to the connected state.
Analogous apparatus, computer programs, and computer program products are provided.
Advantages that may be achieved is that the network is enabled to indicate to the UE whether to, and in that case how to, derive and report early measurements on beam level for the serving cell. There is then no ambiguity for the UE how those beam level measurements should be derived and reported for the serving cell. This allows the network to make sure that the UE reports early measurements for the serving cell that are relevant, e.g. regarding whether it is needed or not from the UE in this specific case, in that case whether to only indicate which are the strongest beams or to also include actual measured values as well, the number of beams to include in the measurement report and what quality threshold to use to determine if a beam should be reported or not.
According to some other embodiments, a method of operating a network node in a communication network includes transmitting, to a user equipment, UE, a configuration to perform a beam level measurement for a serving cell. The method includes receiving a beam level measurement result for the serving cell.
The accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this application, illustrate certain non-limiting embodiments of inventive concepts. In the drawings:
Inventive concepts will now be described more fully hereinafter with reference to the accompanying drawings, in which examples of embodiments of inventive concepts are shown. Inventive concepts may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of present inventive concepts to those skilled in the art. It should also be noted that these embodiments are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present/used in another embodiment.
The following description presents various embodiments of the disclosed subject matter. These embodiments are presented as teaching examples and are not to be construed as limiting the scope of the disclosed subject matter. For example, certain details of the described embodiments may be modified, omitted, or expanded upon without departing from the scope of the described subject matter.
One problem addressed in the present disclosure is that for the early measurements that are performed by a UE that is in RRC_IDLE or RRC_INACTIVE, and which then are reported to the network when the UE transitions to (or has transitioned to) RRC_CONNECTED in NR, there is no configuration for how to derive and report beam level information for the serving cell. In the early measurement configuration, there is a beam level configuration per neighbouring NR frequency, in the corresponding beamMeasConfigIdle-r16, which includes what measurement quantities to use for the beam measurements, a maximum number of beams to report and an indication whether to include beam measurement results according to the configured measurement quantities. Since there is no corresponding configuration for beam level measurements and reporting for the serving cell it is however ambiguous whether the UE should report beam level measurements at all for the serving cell and, in that case, how they should be reported.
It can be noted that in a typical case, the serving cell (where the UE is camping) is on a lower frequency band on FR1 whereas the configured early measurements are for CA/DC candidates on higher frequencies, typically on FR2. As an example, up to 64 beams are supported on FR2 whereas only 4 or 8 beams are supported on FR1. The configuration for beam level measurements would therefore typically differ between the serving cell and the configured neighbouring NR frequencies and it would thus not be relevant to reuse the beam level configuration for a neighbouring frequency for the serving cell. It can also be noted that in case a UE is configured with early measurements only for NE-DC, i.e., with no neighbouring NR frequencies, there would not be any beam level measurement configuration available at all, even though the UE should include measurements for the serving NR cell.
It is thus not clear for the UE whether it should derive and report any measurements on beam level for the serving cell. If the UE anyway decides to do so it is not clear what configuration to use for the corresponding beam level report. This may, for example, lead to a situation in which the UE does not provide any beam level report for the serving cell in the early measurement report even though the network would need it. The information would then be missing for the network, which could negatively impact the usefulness of the early measurement report.
This may also lead to a situation in which the UE does provide a beam level report for the serving cell in the early measurement report, but the network does not know what configuration it is based on, e.g., what measurement quantity that the UE has used. The network might then misinterpret the received measurement information, which may lead to faulty assumptions and decisions. Further, in some situations, the UE does provide a beam level report for the serving cell in the early measurement report even though the network does not need it. The UE would then transmit measurement information to the network in vain, which would lead to unnecessary utilization of UL resources (and power consumption).
As discussed herein, operations of communication device UE may be performed by processing circuitry 603 and/or transceiver circuitry 601. For example, processing circuitry 603 may control transceiver circuitry 601 to transmit communications through transceiver circuitry 601 over a radio interface to a radio access network node (also referred to as a base station) and/or to receive communications through transceiver circuitry 601 from a RAN node over a radio interface. Moreover, modules may be stored in memory circuitry 605, and these modules may provide instructions so that when instructions of a module are executed by processing circuitry 603, processing circuitry 603 performs respective operations (e.g., operations discussed below with respect to Example Embodiments relating to wireless communication devices). According to some embodiments, a communication device UE 600 and/or an element(s)/function(s) thereof may be embodied as a virtual node/nodes and/or a virtual machine/machines.
As discussed herein, operations of the RAN node may be performed by processing circuitry 703, network interface 707, and/or transceiver 701. For example, processing circuitry 703 may control transceiver 701 to transmit downlink communications through transceiver 701 over a radio interface to one or more mobile terminals UEs and/or to receive uplink communications through transceiver 701 from one or more mobile terminals UEs over a radio interface. Similarly, processing circuitry 703 may control network interface 707 to transmit communications through network interface 707 to one or more other network nodes and/or to receive communications through network interface from one or more other network nodes. Moreover, modules may be stored in memory 705, and these modules may provide instructions so that when instructions of a module are executed by processing circuitry 703, processing circuitry 703 performs respective operations (e.g., operations discussed below with respect to Example Embodiments relating to RAN nodes). According to some embodiments, RAN node 700 and/or an element(s)/function(s) thereof may be embodied as a virtual node/nodes and/or a virtual machine/machines.
According to some other embodiments, a network node may be implemented as a core network CN node without a transceiver. In such embodiments, transmission to a wireless communication device UE may be initiated by the network node so that transmission to the wireless communication device UE is provided through a network node including a transceiver (e.g., through a base station or RAN node). According to embodiments where the network node is a RAN node including a transceiver, initiating transmission may include transmitting through the transceiver.
As discussed herein, operations of the CN node may be performed by processing circuitry 803 and/or network interface circuitry 807. For example, processing circuitry 503 may control network interface circuitry 807 to transmit communications through network interface circuitry 807 to one or more other network nodes and/or to receive communications through network interface circuitry from one or more other network nodes. Moreover, modules may be stored in memory 805, and these modules may provide instructions so that when instructions of a module are executed by processing circuitry 803, processing circuitry 803 performs respective operations (e.g., operations discussed below with respect to Example Embodiments relating to core network nodes). According to some embodiments, CN node 800 and/or an element(s)/function(s) thereof may be embodied as a virtual node/nodes and/or a virtual machine/machines.
The present disclosure describes methods for configuration of a wireless terminal/user equipment (UE) 600 how to perform and report beam measurements for the serving cell, where the beam measurements are performed in a dormant state (e.g., RRC_IDLE or RRC_INACTIVE) and where the reporting is done upon the transition from a dormant state to connected state. The methods for the configuration include a specific configuration for serving cell beam level measurements is included in the early measurement configuration. In some embodiments, the UE 600 determines whether to perform and report any beam level measurements for the serving cell, and in that case how to derive and report those measurements, based on that configuration.
In some embodiments, the UE 600 includes beam level reporting for the serving cell only if there is a configuration for the serving frequency, which includes beamMeasConfigIdle-r16 in the early measurement configuration. If such configuration exists, the UE 600 determines how to derive and report the beam level measurements for the serving cell based on that configuration. In some embodiments, the UE 600 includes a beam level report for the serving cell if beamMeasConfigIdle-r16 is configured for any of the neighbouring NR frequencies (either for any of all the configured neighbouring NR frequencies, or for any of the configured neighbouring NR frequencies that are part of the same early measurement report), and correspondingly includes the corresponding measurement results per beam if includeBeamMeasurements-r16 is set for any of those neighbouring NR frequencies. The configuration for beam level reporting for the serving cell could then either be hard coded, specified or based on e.g., the corresponding configuration for cell reselection in SIB2, e.g., as defined by nrofSS-BlocksToAverage and absThreshSS-BlocksConsolidation.
The UE 600 includes a beam level report for the serving cell based on the parameters for cell reselection in SIB2. The same number of beams and/or threshold for the beam measurements as defined by nrofSS-BlocksToAverage and absThreshSS-BlocksConsolidation, respectively, in SIB2 are then used, if defined. If e.g., nrofSS-BlocksToAverage is not configured in SIB2, the UE 600 does not include any beam level measurements for the serving cell in early measurement reports that are sent in the cell. In some embodiments, the beam level reporting for the serving cell is based on a specific neighbouring NR frequency configuration, e.g., the first one in the list, in the early measurement configuration. This could then be based on only the dedicated early measurement configuration, only the broadcasted early measurement configuration, or a combination of those.
It is possible for the network to indicate to the UE 600 whether to, and in that case how to, derive and report early measurements on beam level for the serving cell. There is then no ambiguity for the UE 600 how those beam level measurements should be derived and reported for the serving cell. This allows the network to make sure that the UE 600 reports early measurements for the serving cell that are relevant, e.g., regarding whether it is needed or not from the UE 600 in this specific case, in that case whether to only indicate which are the strongest beams or to also include actual measured values as well, the number of beams to include in the measurement report and what quality threshold to use to determine if a beam should be reported or not.
In another embodiment, the configuration for beam level measurements and reporting for the serving cell is provided to the UE 600 in a separate field or IE in the early measurement configuration. The UE 600 then determines whether to perform and report any beam level measurements for the serving cell based on if it has received this configuration. If the UE 600 has received the configuration, as part of the early measurement configuration, it performs beam level measurements for the serving cell accordingly, i.e., it derives and reports the beam level measurement results for the serving cell according to the received configuration. If the UE 600 has not received the configuration when it is time for reporting of the early measurements, the UE 600 does not include any beam level results for the serving cell in the early measurement report. An example implementation of this alternative can be seen below (with the added parts underlined):
[[

]]
[[
beamMeasConfigIdleServing BeamMeasConfigIdleServing-NR OPTIONAL
]]
In another embodiment, the configuration for beam level measurements and reporting for the serving cell is provided to the UE 600 within one of the MeasIdleCarrierNR-r16 entities in measldleCarrierListNR-r16 that is part of the UE's early measurement configuration. The UE 600 then checks if the serving frequency (i.e., the frequency of the serving cell to which the UE 600 sends the early measurement report upon transition to RRC_CONNECTED) matches the configuration for any of the MeasIdleCarrierNR-r16 entities in the measldleCarrierListNR-r16, e.g., that the carrierFreq and/or ssbSubCarrierSpacing corresponds to the carrier frequency and/or subcarrier spacing for the serving cell. If that is the case, the UE 600 uses the configuration for that MeasIdleCarrierNR-r16 entity to determine whether to perform and/or include beam level measurements for the serving cell in the early measurement report and, if so, how to derive and report those beam level measurement results. For example, if the matching MeasIdleCarrierNR-r16 entity includes beamMeasConfigIdle-r16, the UE 600 determines that beam level measurements shall be performed and reported for the serving cell. Those beam level measurements are then, in an example, performed according to the configuration included in that beamMeasConfigIdle-r16 and possibly the parameter absThreshSS-BlocksConsolidation-r16 that is included in ssb-MeasConfig-r16 in the same MeasIdleCarrierNR-r16 entity.
In one example, the UE 600 does not include any beam level results for the serving cell if there is no MeasIdleCarrierNR-r16 entity in the measldleCarrierListNR-r16 of the UE's early measurement configuration that matches the frequency of the serving cell. In case the UE 600 should report beam level measurements for the serving cell, the network thus includes a configuration for the serving frequency (with beamMeasConfigIdle-r16) in measIdleCarrierListNR-r16. It can be observed that in some cases the corresponding MeasIdleCarrierNR-r16 entity thus may be configured by the network only for configuration of beam level measurements/reporting for the serving cell, e.g., since early measurements on the corresponding frequency may not be useful for configuration of CA or DC (where the SCG or SCell(s) are situated on that frequency).
In another embodiment, the UE 600 determines whether it shall derive and/or report beam level measurements for the serving cell based on the content of the configurations for the neighbouring NR frequencies, i.e., in the MeasIdleCarrierNR-r16 entities in the measldleCarrierListNR-r16. As an example, if any of those entities (i.e., if the early measurement configuration for any of the configured NR neighbouring frequencies) includes a configuration for beam level measurements (beamMeasConfigIdle-r16) then the UE 600 includes a report on beam level also for the serving cell in the early measurement report. In a similar way, the UE 600 determines whether is shall include measurement results (for the related measurement quantity/-ies) for the reported beams for the serving cell. For example, if any of the MeasIdleCarrierNR-r16 entities in the measldleCarrierListNR-r16 has the includeBeamMeasurements-r16 set, the UE 600 performs the corresponding procedure also for the serving cell and thus includes the measurement results.
In one example, some of the configuration to use for the beam level measurements on the serving cell, e.g., corresponding to reportQuantityRS-Indexes-r16 and maxNrofRS-IndexesToReport-r16 in BeamMeasConfigIdle-NR-r16 and the absThreshSS-BlocksConsolidation-r16 in MeasIdleCarrierNR-r16 consist of hard coded and/or specified values. For example, the number of beams (corresponding to maxNrofRS-IndexesToReport-r16) can be set to a value that is related to the frequency band of the serving frequency. In another example, the configuration is instead based on a configuration for cell (re)selection in system information (e.g., in SIB2). For example, the parameter nrofSS-BlocksToAverage in SIB2 is used for the configuration of maxNrofRS-IndexesToReport-r16 for beam level measurements for the serving cell in the early measurements. In a corresponding way, the parameter absThreshSS-BlocksConsolidation in SIB2 is used to determine a threshold (if any) for the beam level measurement reporting for the serving cell in the early measurements.
In another example, the UE 600 uses the beam level configuration for one of the neighbouring NR frequencies in the early measurement configuration that is configured with beam level measurements (i.e., from one MeasIdleCarrierNR-r16 entity in the measldleCarrierListNR-r16 that includes beamMeasConfigIdle-r16) to determine the beam level configuration to use for the serving cell. Which neighbouring NR frequency configuration (MeasIdleCarrierNR-r16 entity in the list) to then use the beam level configuration from can e.g., be configured through dedicated or broadcast signaling, specified, hard coded or determined through UE implementation.
In another alternative, the UE 600 determines whether to derive and report any beam level measurements for the serving cell (for the early measurement report) based on the configuration for cell reselection in system information (e.g., SIB2 in NR). In one example, the UE 600 then derives and reports beam level results if nrofSS-BlocksToAverage is defined in SIB2. In that case, the value could then also be used to determine the maximum number of beams to include in the report.
In yet another alternative, the UE 600 determines whether to derive and report any beam level measurements for the serving cell (for the early measurement report) and in that case how to derive and report the beam level results based on one of the configurations for one of the neighbouring NR frequencies in the early measurement configuration (i.e., from one MeasIdleCarrierNR-r16 entity in the measIdleCarrierListNR-r16). The UE 600 then uses the configuration that is related to beam level measurements for that neighbouring NR frequency also to determine whether to and/or how to do beam level measurements for the serving cell.
Which neighbouring NR frequency configuration (MeasIdleCarrierNR-r16 entity in the list) to then use for the configuration of beam level measurements for the serving cell can e.g., be configured through dedicated or broadcast signaling, specified, hard coded or determined through UE implementation. In one example, it is the first in the list that is stored by the UE. In other examples, it may be the first or the last in the list that was received through dedicated signaling or the first or the last in the list that was received through broadcast signaling. It may also be the first entity or the last entity, in a list of configurations, that includes beamMeasConfigIdle-r16, i.e., that actually contains a beam level configuration, if any.
In yet another example, the beam level configuration for the serving cell is based on the corresponding beam level configuration for more than one of the neighbouring NR frequencies, e.g., as a combination of more than one such configuration or that different parts of the beam level configuration are taken from different neighbouring NR frequency configurations. In one example, which configuration(s) for NR neighbouring frequencies to base the beam level measurement configuration for the serving cell on may be selected through a parameter in the neighbouring NR frequency configuration (i.e., within the MeasIdleCarrierNR-r16 entity), e.g., what frequency or frequency band that it concerns. This could then be used so that the serving cell frequency configuration is based on the configuration for an NR neighbouring frequency that e.g., is considered closest to the serving frequency.
In some embodiments, which of the solutions to use in order to determine whether to perform and/or derive and report beam level measurements for the serving cell and, in that case, the corresponding configuration to then use, can be configured by the network through e.g., dedicated or broadcast signaling. As an alternative it can be specified, hard coded or determined through UE implementation.
In the context of the invention what is called beam measurement information may be interpreted as measurement performed on reference signals (such as SSBs or channel state information-reference signal (CSI-RS) resources) that may be beamformed by the network. Beam measurement information may be beam measurements such as RSRP, RSRQ or SINR (signal to interference and noise ratio) per beam (e.g., SS-RSRP, for RSRP performed on a specific SSB) or information derived from beam measurements, such as a list of beam identifiers where these were selected based on beam measurements e.g., identifiers of strongest beams, or beam above a configurable threshold.
Operations of the communication device 600 (implemented using the structure of the block diagram of
In some embodiments, the early measurement comprises a beam level measurement. In this embodiment, the configuration includes a configuration to perform the beam level measurement and reporting for the serving cell. In some embodiments, the configuration to perform the beam level measurement is provided to the communication device in one of a separate field or an information element (IE) in the early measurement configuration.
According to some embodiments, the configuration to perform the beam level measurement is provided to the communication device in a measurement idle carrier New Radio (NR) entity that is part of the communication device's early measurement configuration. In some embodiments, the method includes determining whether to perform and/or include the beam level measurement for the serving cell in the early measurement report based on a comparison of a serving frequency of the communication device to a configuration of the measurement idle carrier NR entity. For example, communication device 600 determines to perform and/or include the beam level measurement for the serving cell in the early measurement report based on a comparison of a serving frequency of communication device 600 to a configuration of the measurement idle carrier NR entity.
The method includes determining to perform and/or include the beam level measurement for the serving cell in the early measurement report based on a determination the serving frequency of the communication device corresponds to a configuration of the measurement idle carrier NR entity in some embodiments. Alternatively, the method includes determining not to perform and/or include the beam level measurement for the serving cell in the early measurement report based on a determination that the serving frequency of the communication device does not correspond to a configuration of the measurement idle carrier NR entity. Continuing the previous example, communication device 600 determines to perform and/or include the beam level measurement for the serving cell in the early measurement report based on a determination that the serving frequency of communication device 600 corresponds to a configuration of the measurement idle carrier NR entity or determines to not perform and/or include the beam level measurement for the serving cell in the early measurement report based on the determination that the serving frequency of communication device 600 does not correspond to a configuration of the measurement idle carrier NR entity.

Network node 1260 and WD 1210 comprise various components described in more detail below. These components work together in order to provide network node and/or wireless device functionality, such as providing wireless connections in a wireless network. In different embodiments, the wireless network may comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations, and/or any other components or systems that may facilitate or participate in the communication of data and/or signals whether via wired or wireless connections.
As used herein, network node refers to equipment capable, configured, arranged and/or operable to communicate directly or indirectly with a wireless device and/or with other network nodes or equipment in the wireless network to enable and/or provide wireless access to the wireless device and/or to perform other functions (e.g., administration) in the wireless network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)). Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS). Yet further examples of network nodes include multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell/multicast coordination entities (MCEs), core network nodes (e.g., mobile switching centers (MSCs), mobile management entities (MMEs)), operation and maintenance (O&M) nodes, operations support system (OSS) nodes, self-optimized network (SON) nodes, positioning nodes (e.g., evolved-serving mobile location centers (E-SMLCs)), and/or minimization of drive tests (MDTs). As another example, a network node may be a virtual network node as described in more detail below. More generally, however, network nodes may represent any suitable device (or group of devices) capable, configured, arranged, and/or operable to enable and/or provide a wireless device with access to the wireless network or to provide some service to a wireless device that has accessed the wireless network.

Similarly, network node 1260 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which network node 1260 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB's. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, network node 1260 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 1280 for the different RATs) and some components may be reused (e.g., the same antenna 1262 may be shared by the RATs).

For example, network 1343B may be a cellular network, a Wi-Fi network, and/or a near-field network. Power source 1313 may be configured to provide alternating current (AC) or direct current (DC) power to components of UE 1300.
The features, benefits and/or functions described herein may be implemented in one of the components of UE 1300 or partitioned across multiple components of UE 1300. Further, the features, benefits, and/or functions described herein may be implemented in any combination of hardware, software or firmware. In one example, communication subsystem 1331 may be configured to include any of the components described herein. Further, processing circuitry 1301 may be configured to communicate with any of such components over bus 1302. In another example, any of such components may be represented by program instructions stored in memory that when executed by processing circuitry 1301 perform the corresponding functions described herein. In another example, the functionality of any of such components may be partitioned between processing circuitry 1301 and communication subsystem 1331. In another example, the non-computationally intensive functions of any of such components may be implemented in software or firmware and the computationally intensive functions may be implemented in hardware.
In some embodiments, some or all of the functions described herein may be implemented as virtual components executed by one or more virtual machines implemented in one or more virtual environments 1400 hosted by one or more of hardware nodes 1430. Further, in embodiments in which the virtual node is not a radio access node or does not require radio connectivity (e.g., a core network node), then the network node may be entirely virtualized.
The functions may be implemented by one or more applications 1420 (which may alternatively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions, etc.) operative to implement some of the features, functions, and/or benefits of some of the embodiments disclosed herein. Applications 1420 are run in virtualization environment 1400 which provides hardware 1430 comprising processing circuitry 1460 and memory 1490. Memory 1490 contains instructions 1495 executable by processing circuitry 1460 whereby application 1420 is operative to provide one or more of the features, benefits, and/or functions disclosed herein.
Virtualization environment 1400, comprises general-purpose or special-purpose network hardware devices 1430 comprising a set of one or more processors or processing circuitry 1460, which may be commercial off-the-shelf (COTS) processors, dedicated Application Specific Integrated Circuits (ASICs), or any other type of processing circuitry including digital or analog hardware components or special purpose processors. Each hardware device may comprise memory 1490-1 which may be non-persistent memory for temporarily storing instructions 1495 or software executed by processing circuitry 1460. Each hardware device may comprise one or more network interface controllers (NICs) 1470, also known as network interface cards, which include physical network interface 1480. Each hardware device may also include non-transitory, persistent, machine-readable storage media 1490-2 having stored therein software 1495 and/or instructions executable by processing circuitry 1460. Software 1495 may include any type of software including software for instantiating one or more virtualization layers 1450 (also referred to as hypervisors), software to execute virtual machines 1440 as well as software allowing it to execute functions, features and/or benefits described in relation with some embodiments described herein.
Virtual machines 1440 comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by a corresponding virtualization layer 1450 or hypervisor. Different embodiments of the instance of virtual appliance 1420 may be implemented on one or more of virtual machines 1440, and the implementations may be made in different ways.
During operation, processing circuitry 1460 executes software 1495 to instantiate the hypervisor or virtualization layer 1450, which may sometimes be referred to as a virtual machine monitor (VMM). Virtualization layer 1450 may present a virtual operating platform that appears like networking hardware to virtual machine 1440.
As shown in
Virtualization of the hardware is in some contexts referred to as network function virtualization (NFV). NFV may be used to consolidate many network equipment types onto industry standard high volume server hardware, physical switches, and physical storage, which can be located in data centers, and customer premise equipment.
In the context of NFV, virtual machine 1440 may be a software implementation of a physical machine that runs programs as if they were executing on a physical, non-virtualized machine. Each of virtual machines 1440, and that part of hardware 1430 that executes that virtual machine, be it hardware dedicated to that virtual machine and/or hardware shared by that virtual machine with others of the virtual machines 1440, forms a separate virtual network elements (VNE).
Still in the context of NFV, Virtual Network Function (VNF) is responsible for handling specific network functions that run in one or more virtual machines 1440 on top of hardware networking infrastructure 1430 and corresponds to application 1420 in
In some embodiments, one or more radio units 14200 that each include one or more transmitters 14220 and one or more receivers 14210 may be coupled to one or more antennas 14225. Radio units 14200 may communicate directly with hardware nodes 1430 via one or more appropriate network interfaces and may be used in combination with the virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station.
In some embodiments, some signalling can be effected with the use of control system 14230 which may alternatively be used for communication between the hardware nodes 1430 and radio units 14200.

Wireless connection 1670 between UE 1630 and base station 1620 is in accordance with the teachings of the embodiments described throughout this disclosure. One or more of the various embodiments may improve the performance of OTT services provided to UE 1630 using OTT connection 1650, in which wireless connection 1670 forms the last segment. More precisely, the teachings of these embodiments may improve the random access speed and/or reduce random access failure rates and thereby provide benefits such as faster and/or more reliable random access.
A measurement procedure may be provided for the purpose of monitoring data rate, latency and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring OTT connection 1650 between host computer 1610 and UE 1630, in response to variations in the measurement results. The measurement procedure and/or the network functionality for reconfiguring OTT connection 1650 may be implemented in software 1611 and hardware 1615 of host computer 1610 or in software 1631 and hardware 1635 of UE 1630, or both. In embodiments, sensors (not shown) may be deployed in or in association with communication devices through which OTT connection 1650 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which software 1611, 1631 may compute or estimate the monitored quantities. The reconfiguring of OTT connection 1650 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not affect base station 1620, and it may be unknown or imperceptible to base station 1620. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling facilitating host computer 1610's measurements of throughput, propagation times, latency and the like. The measurements may be implemented in that software 1611 and 1631 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using OTT connection 1650 while it monitors propagation times, errors etc.

Further definitions and embodiments are discussed below.
In the above-description of various embodiments of present inventive concepts, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of present inventive concepts. Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which present inventive concepts belong. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
When an element is referred to as being “connected”, “coupled”, “responsive”, or variants thereof to another element, it can be directly connected, coupled, or responsive to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected”, “directly coupled”, “directly responsive”, or variants thereof to another element, there are no intervening elements present. Like numbers refer to like elements throughout. Furthermore, “coupled”, “connected”, “responsive”, or variants thereof as used herein may include wirelessly coupled, connected, or responsive. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Well-known functions or constructions may not be described in detail for brevity and/or clarity. The term “and/or” (abbreviated “/”) includes any and all combinations of one or more of the associated listed items.
It will be understood that although the terms first, second, third, etc. may be used herein to describe various elements/operations, these elements/operations should not be limited by these terms. These terms are only used to distinguish one element/operation from another element/operation. Thus a first element/operation in some embodiments could be termed a second element/operation in other embodiments without departing from the teachings of present inventive concepts. The same reference numerals or the same reference designators denote the same or similar elements throughout the specification.
As used herein, the terms “comprise”, “comprising”, “comprises”, “include”, “including”, “includes”, “have”, “has”, “having”, or variants thereof are open-ended, and include one or more stated features, integers, elements, steps, components or functions but does not preclude the presence or addition of one or more other features, integers, elements, steps, components, functions or groups thereof. Furthermore, as used herein, the common abbreviation “e.g.”, which derives from the Latin phrase “exempli gratia,” may be used to introduce or specify a general example or examples of a previously mentioned item, and is not intended to be limiting of such item. The common abbreviation “i.e.”, which derives from the Latin phrase “id est,” may be used to specify a particular item from a more general recitation.
Example embodiments are described herein with reference to block diagrams and/or flowchart illustrations of computer-implemented methods, apparatus (systems and/or devices) and/or computer program products. It is understood that a block of the block diagrams and/or flowchart illustrations, and combinations of blocks in the block diagrams and/or flowchart illustrations, can be implemented by computer program instructions that are performed by one or more computer circuits. These computer program instructions may be provided to a processor circuit of a general purpose computer circuit, special purpose computer circuit, and/or other programmable data processing circuit to produce a machine, such that the instructions, which execute via the processor of the computer and/or other programmable data processing apparatus, transform and control transistors, values stored in memory locations, and other hardware components within such circuitry to implement the functions/acts specified in the block diagrams and/or flowchart block or blocks, and thereby create means (functionality) and/or structure for implementing the functions/acts specified in the block diagrams and/or flowchart block(s).
These computer program instructions may also be stored in a tangible computer-readable medium that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable medium produce an article of manufacture including instructions which implement the functions/acts specified in the block diagrams and/or flowchart block or blocks. Accordingly, embodiments of present inventive concepts may be embodied in hardware and/or in software (including firmware, resident software, micro-code, etc.) that runs on a processor such as a digital signal processor, which may collectively be referred to as “circuitry,” “a module” or variants thereof.
It should also be noted that in some alternate implementations, the functions/acts noted in the blocks may occur out of the order noted in the flowcharts. For example, two blocks shown in succession may in fact be executed substantially concurrently or the blocks may sometimes be executed in the reverse order, depending upon the functionality/acts involved. Moreover, the functionality of a given block of the flowcharts and/or block diagrams may be separated into multiple blocks and/or the functionality of two or more blocks of the flowcharts and/or block diagrams may be at least partially integrated. Finally, other blocks may be added/inserted between the blocks that are illustrated, and/or blocks/operations may be omitted without departing from the scope of inventive concepts. Moreover, although some of the diagrams include arrows on communication paths to show a primary direction of communication, it is to be understood that communication may occur in the opposite direction to the depicted arrows.
Many variations and modifications can be made to the embodiments without substantially departing from the principles of the present inventive concepts. All such variations and modifications are intended to be included herein within the scope of present inventive concepts. Accordingly, the above disclosed subject matter is to be considered illustrative, and not restrictive, and the examples of embodiments are intended to cover all such modifications, enhancements, and other embodiments, which fall within the spirit and scope of present inventive concepts. Thus, to the maximum extent allowed by law, the scope of present inventive concepts are to be determined by the broadest permissible interpretation of the present disclosure including the examples of embodiments and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
