From a radio perspective, the 5G system started to be standardized in 3GPP, and New Radio (NR) is the name for the radio interface. One of the characteristics of NR is the ability to use higher frequency ranges than those used by Long Term Evolution (LTE). For example, frequency ranges above 6 GHz are enabled. However, these higher frequency ranges are known to have more challenging propagation conditions such as a higher penetration and path loss. To mitigate some of these effects, multi-antenna technologies such as beamforming will be massively used. Yet another NR characteristic is the use of multiple numerologies in downlink (DL) and uplink (UL) in a cell or for a user equipment (UE) and/or in different frequency bands. Yet another characteristic is the possibility to enable shorter latencies.
Both standalone and non-standalone NR deployments have been standardized in 3GPP. The standalone deployments may be single or multi-carrier (e.g., NR carrier aggregation (CA) or dual connectivity (DC) with NR primary cell (PCell) and NR primary secondary cell (PSCell)). The non-standalone deployments are currently meant to describe a deployment with LTE PCell and NR PSCell. There may also be one or more LTE secondary cells (Scells) and one or more NR SCell.
The following deployment options are explicitly captured in NR Work Item Description, RP-170847, New WID on New Radio Access Technology, NTT DoCoMo, March 2018:
In NR, DC can be between Evolved Universal Terrestrial Radio Access (E-UTRA) and NR (the master can be E-UTRA or NR while the secondary serving node can be NR and E-UTRA, respectively) and Dual Connectivity within NR only.
An NG-RAN node (or NR radio network node) is currently either:
The gNBs and ng-eNBs are interconnected with each other by means of the Xn interface. The gNBs and ng-eNBs are also connected by means of the NG interfaces to the SGC, more specifically to the Access and Mobility Management Function (AMF) by means of the NG-C interface and to the User Plane Function (UPF) by means of the NG-U interface. This is discussed in more detail in 3GPP TS 23.501.
With regard to measurements in NR, the UE measures at least one and possibly multiple beams of a cell. The measurements results, which may include power values, are averaged to derive the cell quality. In doing so, the UE is configured to consider a subset of the detected beams. Filtering takes place at two different levels: at the physical layer to derive beam quality and then at Radio Resource Control (RRC) level to derive cell quality from multiple beams. Cell quality from beam measurements is derived in the same way for the serving cell(s) and for the non-serving cell(s). Measurement reports may contain the measurement results of a number of X best beams if the UE is configured to do so by the gNB.
The measurement can be: intra-frequency (including radio link monitoring (RLM) and beam management), inter-frequency, and inter-radio access technology (inter-RAT). NR inter-RAT measurements are performed when the UE is connected to at least another radio access technology (RAT) such as, for example, E-UTRA, but the UE may at the same time be connected also to NR such as, for example, when the UE is in DC with E-UTRA or NR. Intra-frequency neighbour (cell) measurements and inter-frequency neighbour (cell) measurements are defined as follows:
In NR, a beam can be measured, for example, based on SSB, which may also be known as SS/PBCH block in 3GPP TS 38.211, CSI-RS, or their combination. CSI-RS is specified in 3GPP TS 38.211.
Polar coding is used for PBCH.
The UE may assume a band-specific sub-carrier spacing for the SS/PBCH block unless a network has configured the UE to assume a different sub-carrier spacing.
PBCH symbols carry its own frequency-multiplexed DMRS.
QPSK modulation is used for PBCH.
The PBCH physical layer model is described in 3GPP TS 38.202.
With regard to static UE beam measurement capability, in LTE and earlier 3GPP RATs, the UE was measuring cells and not different beams of the cell(s), therefore there was no UE beam measurement capabilities.
In NR, UE beam measurement capability has been discussed in terms of the number of beams per each cell (in combination with the total number of cells, so the number beams per cell times the number of cells defines the number of beams per carrier) and/or the total number of beams per carrier (without defining the per-cell beam measurement capability) without differentiating between the carriers. This capability is statically defined in the UE and does not depend on the current CA configuration or the number of configured carriers or coverage level.
In the context of beam measurement capability, it should be emphasized that the discussion is about the number of beams transmitted by the gNB (e.g. number of SSB and/or number of CSI-RS) which are measured by the UE. The UE may also use receive beamforming to perform measurements. However, the number of UE receive beams is generally understood to be a UE implementation matter which does not need to be standardized.
There currently exist certain challenge(s). For example, the UE beam measurement capability discussed so far is static and does not depend, for example, on the current CA configuration or the number of configured carriers in the UE.
In general, NR is a multi-beam operation system. UEs with a higher beam measurement capability benefit multi-beam system operation, but at the same time this introduces more complexity in the UE. It may increase the power consumption in the UE and increase the cost of the UE due to the increased measurement processing. Additionally, UE complexity and power consumption are increased when the UE is configured with multiple carriers such as, for example, in carrier aggregation and/or in multiple connectivity such as EN-DC. Thus, there is a need to find the best trade-off from the system and the UE point of view.
To address the foregoing problems with existing solutions, disclosed is systems and methods for controlling adaptive beam measurement capability.
According to certain embodiments, a method by a wireless device is provided for controlling adaptive beam measurement capability. The method includes identifying a type of serving carrier of a serving cell and allocating at least one resource for beam measurement based on the type that was identified.
According to certain embodiments, a wireless device is provided for controlling adaptive beam measurement capability. The wireless device includes memory operable to store instructions and processing circuitry operable to execute the instructions to cause the wireless device to identify a type of serving carrier of a serving cell and allocate at least one resource for beam measurement based on the type that was identified.
According to certain embodiments, a method by a network node is provided for controlling an adaptive beam measurement capability of a wireless device. The method includes transmitting, to the wireless device, a configuration for performing one or more beam measurements based on a type of serving carrier of a serving cell and receiving information associated with the one or more beam measurements performed based on the configuration and the type of serving carrier.
According to certain embodiments, a network node is provided for controlling an adaptive beam measurement capability of a wireless device. The network node includes memory operable to store instructions and processing circuitry operable to execute the instructions to cause the network node to transmit, to the wireless device, a configuration for performing one or more beam measurements based on a type of serving carrier of a serving cell and receive information associated with the one or more beam measurements performed based on the configuration and the type of serving carrier.
Certain embodiments may provide one or more of the following technical advantages. For example, one technical advantage may be that certain embodiments provide the possibility to adapt a user equipment's beam measurements capability to its configuration, such as, for example, number of configured carriers for the measurements, number of configured component carriers (CCs), number of configured and activated CCs, number of configured but deactivated CCs, coverage level, user equipment (UE) activity level, etc.
Another technical advantage may be that certain embodiments optimize UE complexity, power consumption and processing. This may be especially true when the UE is configured with two or more carriers for measurements.
Still another technical advantage may be that certain embodiments may enhance the performance of procedures (e.g. mobility, beam management, scheduling etc.), which rely on beam measurements.
Yet another technical advantage may be that certain embodiments optimize the UE beam measurements capability depending on the UE configuration or coverage level, in order to compromise this UE capability when the measurements demand is becoming too high due to the UE's configuration.
Other advantages may be readily apparent to one having skill in the art. Certain embodiments may have none, some, or all of the recited advantages.

According to certain embodiments,
In some embodiments, a more general term “network node” may be used and may correspond to any type of radio network node or any network node, which communicates with a user equipment (UE) (directly or via another node) and/or with another network node. Examples of network nodes are NodeB, master eNB (MeNB), slave eNB (SeNB), a network node belonging to master cell group (MCG) or slave cell group (SCG), base station (BS), multi-standard radio (MSR) radio node such as MSR BS, eNodeB, gNodeB, network controller, radio network controller (RNC), base station controller (BSC), relay, donor node controlling relay, base transceiver station (BTS), access point (AP), transmission points, transmission nodes, remote radio unit (RRU), remote radio head (RRH), nodes in distributed antenna system (DAS), core network node (e.g. MSC, mobility management entity (MME), etc.), Operations & Maintenance (O&M), Operations Support System (OSS), Self-Organizing Network (SON), positioning node such as for example an Enhanced-Serving Mobile Location Center (E-SMLC), Minimization of Drive Test (MDT), test equipment (physical node or software), etc.
In some embodiments, the non-limiting term user equipment (UE) or wireless device may be used and may refer to any type of wireless device communicating with a network node and/or with another UE in a cellular or mobile communication system. Examples of UE are target device, device to device (D2D) UE, machine type UE or UE capable of machine to machine (M2M) communication, personal data assistant (PDA), PAD, Tablet, mobile terminals, smart phone, laptop embedded equipped (LEE), laptop mounted equipment (LME), Universal Serial Bus (USB) dongles, UE category M1, UE category M2, Proximity Services (ProSe) UE, vehicle-to-vehicle (V2V) UE, vehicle-to-anything (V2X) UE, etc.
The embodiments are described for NR. However, the embodiments are applicable to any radio access technology (RAT) or multi-RAT systems, where the UE receives and/or transmit signals (e.g. data) e.g. standalone NR, non-standalone NR, 5G, LTE frequency division duplex (FDD)/time division duplex (TDD), Wideband Code Division Multiple Access (WCDMA)/High Speed Packet Access (HSPA), Global Systems for Mobile (GSM)/GSM EDGE Radio Access Network (GERAN), Wi Fi, WLAN, CDMA2000, etc.
The term time resource used herein may correspond to any type of physical resource or radio resource expressed in terms of length of time. Examples of time resources are: symbol, mini-slot, time slot, subframe, radio frame, TTI, interleaving time, etc. The term TTI used herein may correspond to any period of time over which a physical channel can be encoded and interleaved for transmission. The physical channel is decoded by the receiver over the same period of time (TO) over which it was encoded. The TTI may also interchangeably called as short TTI (sTTI), transmission time, slot, sub-slot, mini-slot, short subframe (SSF), mini-subframe etc.
The embodiments described herein may apply to any RRC state, e.g., RRC_CONNECTED, RRC_IDLE, or INACTIVE.
The term beam used herein comprises any directional transmission or reception or their combination (e.g., when there is association in a node between a transmit beam and receive beam). This may be achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference (or gain) while others experience destructive interference (or loss). The signals/channels can be associated with a specific beam through its time-frequency resource or absolute or relative time-frequency resource location index (e.g., synchronization signal block (SSB) index or signal location index within a block; first SSB within a set of SSBs transmitted within SS/PBCH Block Measurement Time Configuration (SMTC) window corresponds to beam X, second SSB within a set of SSBs transmitted within SMTC window corresponds to beam Y, etc.) wherein a signal from a certain beam is transmitted in the corresponding time-frequency resources or a set of time-frequency resources, through its signal sequence which may be generated based on a beam index, through the beam-specific information (e.g., beam index, etc.) transmitted via the channel (e.g., PBCH may contain beam index information), etc. A beam may be characterized by or further associated with its identity (mapping to a certain beam or beam configuration), main beam direction (e.g., degrees in 2D or 3D space), coordinates characterizing the main beam direction as projected to the coordinates planes or a cube of a predefined dimension, transmission (TX) power, beam width, SSB index, frequency, etc.
UE beam measurement capability or beam measurement capacity is the UE's ability to handle a certain amount of beam measurements in parallel (e.g., over a certain time period or during one or more time resources), which in order to support such capability implies the ability of one or more of: allocating the necessary amount of memory or buffers, allocating the necessary amount of processing resources, configuring one or more receivers/transmitters in a certain way (e.g., scheduling, antenna (re)configuration, RF (re)tuning) in one or more time resources to be able to receive/transmit the signals/channel corresponding to such UE capability, using or controlling the power or energy in a certain way to be able to support such UE capability, (re)distributing or scheduling the beam measurements related tasks in a certain way between different hardware/middleware/software units of the UE to support such UE capability, receiving or transmitting over a certain total bandwidth and carrier frequency combinations associated with the supported beam measurements, etc.
The term beam measurement used herein may comprise any measurement performed based on beam-specific time and/or frequency resources (e.g., SSB-based measurement in the resources associated with a specific beam which may comprise the resources configured for SSBs with one or more different SSB indexes and the same cell identifier) and/or beam-specific signals or channels (e.g., channel state information-reference signal (CSI-RS), Demodulation Reference Signal (DMRS), a beam-specific signal for positioning, etc.), wherein beams can be transmit beam, receive beams, or a combination of transmit and receive beams (e.g., when there is association between transmit and receive beams in the node). A beam measurement can be performed for different purposes: Radio Link Monitoring (RLM), beam management, beam failure detection and recovery, Radio Resource Management (RRM), mobility, positioning, etc. Examples of beam measurements: Synchronization Signal-Reference Signal Received Power (SS-RSRP), Synchronization Signal-Reference Signal Received Quality (SS-RSRQ), Synchronization Signal-Signal to Noise Interference Ratio (SS-SINR), CSI-RS based RSRP, CSI-RS based RSRQ, CSI-RS based SINR, Layer 1 measurements (not filtered at Layer 3) such as Layer 1 RSRP, CSI, SINR (for RLM), Es/Iot, transmit power of a beam, etc. A beam measurement may be further associated with a specific coverage enhancement or coverage level.
The embodiments are applicable to single carrier as well as to multicarrier operation of the UE. Examples of multicarrier operation of the UE are carrier aggregation (CA) and multi-connectivity (MC) where Dual Connectivity (DC) is a special case. In CA the UE is able to receive and/or transmit data to more than one serving cells. Dual Connectivity (DC) is a special case or example of MC. The DC comprises one main cell group (MCG) containing at least primary cell (PCell) and one secondary cell group (SCG) containing at least primary secondary cell (PSCell). The term carrier aggregation (CA) is also called (e.g. interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. In CA one of the component carriers (CCs) is the primary component carrier (PCC) or simply primary carrier or even anchor carrier. The remaining ones are called secondary component carrier (SCC) or simply secondary carriers or even supplementary carriers. The serving cell is interchangeably called as primary cell (PCell) or primary serving cell (PSC). Similarly the secondary serving cell is interchangeably called as secondary cell (SCell) or secondary serving cell (SSC). In one example of DC operation involving E-UTRA and NR, the E-UTRA is the master. In another example of the DC operation involving E-UTRA and NR, NR is the master. The DC operation may also involve only NR serving cells (e.g. NR PCell, NR PSCell and NR SCells) or LTE serving cells (e.g. LTE PCell, LTE PSCell and LTE SCells).
The term activation or SCell activation used herein may refer to activation of a serving cell, addition of serving cell, configuration of serving cell etc. The term deactivation or SCell deactivation may refer to deactivation of serving cell, release of serving cell, deconfiguration of serving cell etc. Examples of serving cell that can be configured but deactivated are SCell, PSCell etc. The SCell can also be in an intermediate state between activation and deactivation called herein as dormant state or dormant SCell state, in which case the UE does not receive control or data channel but it can still estimate and report CSI (e.g., channel quality indicator (CQI)) to the network node. In the activation state, the UE can receive and transmit any signal including data and control channels (e.g., physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), etc.). In the deactivated state, the UE does not receive any control channel or data channels. The UE also does not transmit any CSI measurements to the network node in the deactivated state. The deactivated and dormant states are used for saving UE power. Examples of activation procedure are activation of SCell, addition of PSCell etc. SCell activation may also be called as SCell addition. Examples of deactivation procedure are deactivation of SCell, release of PSCell etc.
According to certain embodiments described herein, the UE may operate using coverage enhancement (CE) with regard to a cell, for example, cell 1 or at different coverage levels. The coverage level can be configured by the network or autonomously by the UE. The CE level of the UE is also interchangeably called as coverage level of the UE. The CE level can be expressed in terms of:
The CE level of the UE be defined with respect to any cell such as serving cell, a neighbor cell, a reference cell, etc. For example, it can be expressed in terms of received signal quality and/or received signal strength at the UE with regard to a target cell on which it performs one or more radio measurements. Examples of signal quality are signal-to-noise ratio (SNR), SINR, CQI, narrowband RSRQ (NRSRQ), RSRQ, CRS Es/Iot, SCH Es/Iot, etc. Examples of signal strength are path loss, RSRP, NRSRP, SCH RP etc. The notation Es/Iot is defined as ratio of
The CE level can be expressed in at least two different levels. Consider an example of two different CE levels defined with regard to signal quality (e.g. SNR) at the UE comprising of:
In the above example, the CE1 may also be interchangeably called as normal coverage level (NCL), baseline coverage level, reference coverage level, basic coverage level, legacy coverage level etc. On the other hand, CE2 may be termed as enhanced coverage level or extended coverage level (ECL).
According to particular embodiments, a parameter defining coverage level of the UE with respect to a cell may also be signalled to the UE by the network node. Examples of such parameters are CE Mode A and CE Mode B signalled to UE category M1, UE category M2 etc. The UE configured with CE Mode A and CE Mode B are also said to operate in normal coverage and enhanced coverage respectively.
It may be noted that even though the embodiments in this document are described for a UE, the same or similar embodiments can also be implemented for any radio node (e.g., UE or radio network node), which can transmit radio signals, receive radio signals or both.
According to certain embodiments, the UE may also be configured with different activity levels, e.g., DRX or non-DRX, or different DRX cycle lengths and/or DRX ON duration periods, measurement cycle lengths (may be used e.g. for measurements on deactivated CCs), etc. The activity level may be configured by the network and/or configured autonomously (for all or at least some of the parameters determining the UE activity-level) by the UE. The UE may operate with discontinuous reception (DRX), whereby it monitors PDCCH periodically according to a configured DRX cycle or cycles, for a configured DRX on duration. When the UE is scheduled, an inactivity timer is started and the UE monitors each PDCCH continuously until such time as the inactivity timer expires. A short and long DRX cycle may be configured. When DRX is in use, the UE is only required to perform measurements according to requirements which are relaxed compared to the non DRX measurements, allowing it to save power by also not measuring during the time when the UE is not required to monitor PDCCH. When dual connectivity is configured, cells in the master cell group (MGC) use a DRX cycle which follows that of the PCell, and cells in the so called secondary cell group (SCG) use a DRX cycle which follows that of the PSCell.
UE beam measurement capability is defined generally above. Herein, we enhance UE beam measurement capability by distinguishing between at least two types of beam measurements for each of the intra-frequency, inter-frequency, and inter-RAT beam measurements. In the embodiments the UE beam measurement capability is adaptive in a sense that the number of beams to be measured by the UE are adapted based on number of carriers and/or type of carriers configured for the beam measurements.
The enhanced UE beam measurement capability may be specified for up to a certain number of carriers such as, for example, up to C1 intra-frequency carriers for the enhanced intra-frequency beam measurement capability, up to C2 intra-frequency carriers for the enhanced inter-frequency beam measurement capability, or up to C3 intra-frequency carriers for the enhanced inter-RAT beam measurement capability, etc. If the number of carriers may be exceeded, then such UE configuration may be avoided to ensure that the UE is operating according to its capability or is not requested for more than it can support. Such a configuration management embodiment can be implemented in the UE and/or in the network, as described below.
According to certain embodiments, the enhanced beam measurements capability may also be for one or more specific UE configurations, for a current UE configuration, for a reference UE configuration, i.e., may comprise one, some or all UE beam measurement capabilities, etc.
Certain embodiments described herein relate to intra-frequency and deactivated CC beam measurements. For example, in a particular embodiment, the UE beam measurement may further comprise X1 beam measurements over all intra-frequency carriers of a first type and X2 beam measurements over all intra-frequency carriers of a second type. In general, there may be n (n>1) types of intra-frequency beam measurements and correspondingly X1, X2, . . . , Xn.
In certain particular embodiments, X1, X2, . . . , Xn may be the same (in one example) or different (in another example) in different RRC states.
In other particular embodiments, X1, X2, . . . , Xn may be the same (in one example) regardless of the UE activity level configuration (e.g., DRX cycle length or measurement periodicity) or different (in another example) depending on the UE activity level configuration (e.g., UE has a higher capability Xi′ (Xi<Xi′ for at least one i) when the UE is configured with a higher activity level such as non-DRX (versus DRX which is a lower activity level) or shorter DRX (versus longer DRX which is lower activity level)).
In yet other particular embodiments, X1, X2, . . . , Xn may be the same (in one example) for any number of intra-frequency carriers such as, for example, for any number of configured CCs or disregard of the maximum number of supported CCs by the UE. In another example, X1, X2, . . . , Xn may be depend on the number of intra-frequency carriers configured for intra-frequency measurements, e.g., the number of configured CCs or the maximum number of supported CCs by the UE; for example, there can be X1, X2, . . . , Xn when the number of intra-frequency carriers is not smaller than a threshold, and X1′, X2′, . . . , Xn′ when the number of intra-frequency carriers is above a threshold, where Xi<Xi′ for at least one i.
In another example embodiment, the UE may support X1, X2, . . . , Xn when configured with a first CA type (e.g., intra-band CA), and the UE may support X1′, X2′, . . . , Xn′ when configured with a second CA type (e.g., inter-band CA).
In yet another example embodiment, the UE may support X1, X2, . . . , Xn for NR intra-frequency carriers when configured with no DC, and the UE may support X1′, X2′, . . . , Xn′ for NR intra-frequency carriers when configured with any or some specific DC type (e.g., EN-DC). In still another example embodiment, the UE may support X1, X2, . . . , Xn for NR intra-frequency carriers when configured with a first DC type (e.g., EN-DC), and the UE may support X1′, X2′, . . . , Xn′ for NR intra-frequency carriers when configured with a second DC type (e.g., NR-NR DC).
According to a particular embodiment, if there is also defined per-carrier UE beam measurement capability X, then it may be that: X1+X2+ . . . +Xn<X*N or Xi<X*N (for at least one of i=1, 2, . . . , n) or Xi<X*N_i (for at least one of i=1, 2, . . . , n), where N is the total number of intra-frequency carriers for the UE, and N_i (N_i<=N) is the number intra-frequency carriers associated with the type i of beam measurements (N_i=N when the beam measurements of type i are performed over all N carriers). In this case, for any combination of the parameters X, Xi, N, and N_i, the UE shall be capable to support each of the capabilities X and Xi (i=1, 2, . . . , n, for any i which is applicable for a given UE configuration; e.g. if X2 is for the deactivated CCs and UE is not configured with deactivated CCs then i=2 is not applicable), but also a combined function of X and Xi for the applicable values of i, e.g., one or more of:
Some examples of different intra-frequency beam measurement types are provided. Any one or a combination may apply. For example, an example combination is when two different types are subtypes Xi_a and Xi_b of the type i and the UE shall meet all subtype-level capabilities and a combined function of the subtype-level and type-level capabilities e.g. min(Xi,Xi_a,Xi_b) or min(Xi,(Xi_a+Xi_b))):
Certain embodiments may relate to inter-frequency measurements, and the embodiments described above for intra-frequency beam measurements and beam measurements on deactivated carriers may be adapted for inter-frequency beam measurements.
According to certain embodiments, the UE beam measurement capability may further comprise Y1 beam measurements over all inter-frequency carriers of a first type and Y2 beam measurements over all inter-frequency carriers of a second type. In general, there may be m (m>1) types of inter-frequency beam measurements and correspondingly Y1, Y2, . . . , Ym.
According to particular embodiments, Y1, Y2, Ym may be the same (in one example) or different (in another example) in different RRC states.
According to other particular embodiments, Y1, Y2, . . . Ym may be the same (in one example) disregard of the UE activity level configuration (e.g., DRX cycle length or measurement periodicity) or different (in another example) depending on the UE activity level configuration (e.g., UE has a higher capability Yi′ (Yi<Yi′ for at least one i) when the UE is configured with a higher activity level such as non-DRX (versus DRX which is a lower activity level) or shorter DRX (versus longer DRX which is lower activity level)).
According to other particular embodiments, Y1, Y2, . . . , Ym may be the same (in one example) disregard of the UE CA configuration or UE CA capability or different (in another example) depending on the UE CA configuration or UE CA capability (e.g., a higher capability for UE with a higher CA capability; or a smaller inter-frequency capabilities Y1, . . . Ym when the UE is configured with CA compared to non-CA case since some of the UE resources are need for CA and thus less available resources for inter-frequency).
According to certain embodiments, if there is also defined per-carrier UE beam measurement capability Y, then it may so that: Y1+Y2+ . . . +Ym<Y*N or Yi<X*N (for at least one of i=1, 2, . . . , m) or Yi<Y*N_i (for at least one of i=1, 2, . . . , m), where N is the total number of inter-frequency carriers for the UE, and N_i (N_i<=N) is the number inter-frequency carriers associated with the type i of beam measurements (N_i=N when the beam measurements of type i are performed over all N carriers). In this case, for any combination of the parameters Y, Yi, N, and N_i, the UE shall be capable to support each of the capabilities Y and Yi (i=1, 2, . . . , m, for any i which is applicable for a given UE configuration), but also a combined function of Y and Yi for the applicable values of i, e.g., one or more of:
Examples of different inter-frequency beam measurement types are provided. Any one or a combination may apply. For example, an example combination is when two different types are subtypes Xi_a and Xi_b of the type i and the UE shall meet all subtype-level capabilities and a combined function of the subtype-level and type-level capabilities such as min(Xi,Xi_a,Xi_b)):
The embodiments for intra-frequency beam measurements and beam measurements on deactivated carriers, as described above, may also be adapted for inter-RAT beam measurements.
In a particular embodiment, the UE beam measurement may further comprise Z1 beam measurements over all inter-RAT carriers of a first type and Z2 beam measurements over all inter-RAT carriers of a second type. In general, there may be k (k>1) types of inter-RAT beam measurements and correspondingly Z1, Z2, . . . , Zk. Z1, Z2, . . . , Zk may be defined for a single RAT.
In particular embodiments, Z1, Z2, . . . , Zk may be the same (in one example) or different (in another example) in different RRC states.
In other particular embodiments, Z1, Z2, . . . Zk may be the same (in one example) disregard of the UE activity level configuration (e.g., DRX cycle length or measurement periodicity) or different (in another example) depending on the UE activity level configuration (e.g., UE has a higher capability Zi′ (Zi<Zi′ for at least one i) when the UE is configured with a higher activity level such as non-DRX (versus DRX which is a lower activity level) or shorter DRX (versus longer DRX which is lower activity level)).
In still other particular embodiments, Z1, Z2, . . . , Zk may be the same (in one example) disregard of the UE CA configuration or UE CA capability or different (in another example) depending on the UE CA configuration or UE CA capability (e.g., a higher capability for UE with a higher CA capability; or a smaller inter-RAT capabilities Z1, . . . Zk when the UE is configured with CA compared to non-CA case since some of the UE resources are need for CA and thus less available resources for inter-RAT).
According to a particular embodiment, if there is also defined per-carrier UE beam measurement capability Z, then it may so that: Z1+Z2+ . . . +Zk<Z*N or Zi<Z*N (for at least one of i=1, 2, . . . , k) or Zi<Z*N_i (for at least one of i=1, 2, . . . , k), where N is the total number of inter-RAT carriers for the UE, and N_i (N_i<=N) is the number inter-RAT carriers associated with the type i of beam measurements (N_i=N when the beam measurements of type i are performed over all N carriers). In this case, for any combination of the parameters Z, Zi, N, and N_i, the UE shall be capable to support each of the capabilities Z and Zi (i=1, 2, . . . , k, for any i which is applicable for a given UE configuration), but also a combined function of Z and Zi for the applicable values of i, e.g., one or more of:

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.

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., MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (e.g., E-SMLCs), and/or MDTs.

In certain scenarios in which network node 160 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 160 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 180 for the different RATs) and some components may be reused (e.g., the same antenna 162 may be shared by the RATs).
