Patent Application
20230189251
The present application relates generally to a wireless communication network, and relates more particularly to capability signaling in such a network.
Cross-slot scheduling is one of the mechanisms introduced in New Radio (NR) Rel-16 to allow user equipment (UE) power saving. The UE is configured with a minimum scheduling offset restriction that allows the UE opportunity to micro-sleep by ensuring a minimum gap between a control channel and the corresponding downlink signal/channel that a UE is expected to receive based on the Downlink Control Information (DCI) in the control channel, e.g., a Physical Downlink Control Channel (PDCCH). A similar gap may be ensured between a control channel and an uplink transmission for uplink. The same minimum gap that applies to Physical Downlink Shared Channel (PDSCH) scheduling is also applied for aperiodic Channel State Information Reference Signal (A-CSI RS) reception. Thus, the two parameters (KO or PDCCH-to-PDSCH scheduling offset) and A-CSI triggering offset have some inter-dependencies, when a UE is configured with a minimum scheduling offset restriction.
The value ranges for minimum KO value (0 to 16), A-CSI-RS triggering offset (e.g. {0, 1, 2, 3, 4, 16, 24} slots.), UE assistance related to minimum KO values, and possible set of KO values (0 to 32) may have different values and ranges, which can lead to undesirable scheduling restrictions or delays in cases with mismatch. For example, if a minimum KO value of 5 is enforced, the network may be forced to use a large A-CSI-RS triggering offset (e.g. 16 slots). Therefore, the value range of A-CSI-RS triggering offset was extended for cross-slot scheduling. For other reasons, the value range of A-CSI-RS triggering offset was extended for cross-carrier A-CSI triggering with different numerologies between PDCCH and CSI-RS. There currently exist certain challenge(s). Existing signaling proves insufficient for the network to unambiguously know a UE's capability to support the extended value range of A-CSI-RS triggering offset, at least under some conditions for the cross-slot scheduling case. The conditions may include for instance a condition under which the extended range can be configured for a UE indicating support of such capability.
Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges. Some embodiments use UE capability signaling to explicitly indicate to the network whether and under what conditions the extended offset value range for A-CSI-RS triggering offset is supported, e.g., for cross-slot scheduling based UE power savings and/or for cross-carrier A-CSI-RS triggering with different numerologies.
In some embodiments, a UE indicating support for “Cross Slot Scheduling” also indicates the capability (e.g. implicitly or explicitly) to support the new Radio Resource Control (RRC) parameter (e.g. aperiodicTriggeringOffsetExt-r16.) and/or the extended offset value range for A-CSI-RS triggering offset. For example, in the implicit case, support of extended offset value range for A-CSI triggering offset via aperiodicTriggeringOffsetExt-r16 can become a component within the capability to “Cross Slot Scheduling”.
In other embodiments, a UE indicates a separate capability to support the new RRC parameter (e.g. aperiodicTriggeringOffsetExt-r16.) and/or the extended offset value range for A-CSI triggering offset. For example, the capability can be separate from the capability indicating support for “Cross slot scheduling”.
Certain embodiments may provide one or more of the following technical advantage(s).
Some embodiments make the UE capability unambiguous with respect to the support of extended offset value range for A-CSI-RS triggering offset, e.g., for the case with cross-slot scheduling based power savings.
Generally, then, some embodiments herein include a method performed by a wireless device. The method comprises transmitting signaling which indicates that the wireless device supports cross-slot scheduling. Support for cross-slot scheduling indicates a range of values that the wireless device supports for a triggering offset. Here, a triggering offset is an offset between a slot containing downlink control information that triggers a set of aperiodic channel state information reference signal, CSI-RS, resources and a slot in which the set of aperiodic CSI-RS resources is transmitted.
In some embodiments, the method further comprises, after transmitting the signaling, receiving a control message that configures the wireless device with a triggering offset that has a value within the indicated range of values. In one or more of these embodiments, the control message includes a first parameter configurable to indicate a triggering offset within the indicated range of values.

In one or more of these embodiments, the method further comprises, based on the triggering offset configured by the received control message, operating in a sleep state between the first slot and the second slot. In one or more of these embodiments. the downlink control information is received from a first cell and the CSI-RS is received from a second cell. In this case, the second cell has a higher subcarrier spacing, SCS, than the first cell.

Of course, the present invention is not limited to the above features and advantages. Indeed, those skilled in the art will recognize additional features and advantages upon reading the following detailed description, and upon viewing the accompanying drawings.
In some embodiments, a network node 15 transmits to the wireless device 12 a control message 22 that configures the wireless device 12 with a value to be used for the triggering offset 20. The control message 22 may for example include one or more triggering offset parameters 24, each of which can be set to any of multiple possible values in order to signal which of those values is to be used for the triggering offset 20. Where the wireless communication network 10 conforms to 3GPP specifications, for instance, the triggering offset parameter(s) 24 may include an aperiodicTriggeringOffset parameter and/or an aperiodicTriggeringOffsetExt-r16 parameter. In this case, then, the aperiodicTriggeringOffset parameter can be set to any of the values 0 . . . 6, with the value 0 corresponding a triggering offset 20 of 0 slots, the value 1 corresponding a triggering offset 20 of 1 slot, the value 2 corresponding a triggering offset 20 of 2 slots, the value 3 corresponding a triggering offset 20 of 3 slots, the value 4 corresponding a triggering offset 20 of 4 slots, the value 5 corresponding a triggering offset 20 of 16 slots, and the value 6 corresponding a triggering offset 20 of 24 slots.
Alternatively or additionally, the aperiodicTriggeringOffsetExt-r16 parameter can be set to any of the values 0 . . . 31, with the value itself indicating that the triggering offset 20 is to have the same value, e.g., a value of 5 corresponds to a triggering offset 20 of 5 slots, a value of 30 corresponds to a triggering offset 20 of 30 slots, etc. In these and other embodiments, then, different triggering offset parameters 24 may have different ranges of possible values for the triggering offset 20.
According to some embodiments, the wireless device 12 transmits (e.g., to the network node 15) signaling 26 which indicates a range of values that the wireless device 12 supports for the triggering offset 20. By indicating the range of values that the wireless device 12 supports for the triggering offset 20, the network node 15 may more suitably configure the triggering offset 20 (e.g., via the control message 22). The network node 15 may for example advantageously configure the triggering offset 20 without any restrictions on configurability.
More particularly, in some embodiments, the signaling 26 indicates a range of values that the wireless device 12 supports for the triggering offset 20 by indicating that the wireless device supports a range of values for the triggering offset that is extended as compared to a range of values supportable by another type of wireless device for the triggering offset. The signaling 26 may for instance indicate that the wireless device 12 supports a certain triggering offset parameter in the control message 22, e.g., by indicating that the wireless device 12 supports the aperiodicTriggeringOffsetExt-r16 parameter, which is extended in range as compared to the aperiodicTriggeringOffset parameter. Alternatively or additionally, the signaling 26 may indicate a range of values that the wireless device 12 supports for the triggering offset 20 by indicating that the wireless device supports a range of values for the triggering offset according to a certain 3GPP Release, e.g., Release 16. Alternatively or additionally, the signaling 26 may indicate a range of values that the wireless device 12 supports for the triggering offset 20 by indicating that the wireless device 12 supports a range of values for the triggering offset 20 that includes values above a value threshold (e.g., above X=24) and/or that includes a number of values above a range size threshold (e.g., more than the 7 possible values of the aperiodicTriggeringOffset parameter). Alternatively or additionally, the signaling 26 may indicate a range of values that the wireless device 12 supports for the triggering offset 20 by indicating that the wireless device 12 supports a range of values for the triggering offset 20 that comprises values between 0 and 31. Alternatively or additionally, the signaling 26 may indicate a range of values that the wireless device 12 supports for the triggering offset 20 by indicating which values the wireless device 12 supports for the triggering offset 20.
Note that the signaling 26 may indicate any of the above explicitly or implicitly. The signaling 26 may indicate any of the above explicitly, for instance, if the signaling 26 includes one or more parameters whose value(s) directly represent or convey the above information, e.g., a parameter whose value directly indicates that the wireless device 12 supports the aperiodicTriggeringOffsetExt-r16 parameter or whose value directly indicates the range of values supported for the triggering offset 20. In these and other embodiments, the signaling 26 may indicate the range of values that the wireless device 12 supports for the triggering offset 20 independent of any support by the wireless device 12 for cross-slot scheduling and/or for cross-carrier aperiodic CSI-RS triggering with different subcarrier spacing.
By contrast, the signaling 26 may indicate any of the above implicitly, for instance, if the signaling 26 includes one or more parameters whose value(s) explicitly represent or convey something else, with the above information merely being implied or deduced therefrom. For example, in some embodiments, the signaling 26 explicitly indicates that the wireless device 12 supports cross-slot scheduling, and the wireless device's support for cross-slot scheduling implies that the wireless device 12 supports a certain range of values for the triggering offset 20, e.g., a range of 0 . . . 31 in accordance with the aperiodicTriggeringOffsetExt-r16 parameter. Alternatively or additionally, in other implicit signaling embodiments, the signaling 26 explicitly indicates that the wireless device 12 supports cross-carrier aperiodic CSI-RS triggering with different subcarrier spacing, and the wireless device's support for cross-carrier aperiodic CSI-RS triggering with different subcarrier spacing implies that the wireless device 12 supports a certain range of values for the triggering offset 20, e.g., a range of 0 . . . 31 in accordance with the aperiodicTriggeringOffsetExt-r16 parameter.
In view of the above modifications and variations,
Note that, in some embodiments where the signaling 26 indicates the range of values implicitly, the signaling 26 may actually indicate that the wireless device 12 supports cross-slot scheduling, where such support for cross-slot scheduling indicates that the wireless device 12 supports a certain range of values for the triggering offset 20, e.g., a range of 0 . . . 31 in accordance with the aperiodicTriggeringOffsetExt-r16 parameter.
In some embodiments, the method also comprises, after transmitting the signaling 26, receiving a control message 22 that configures the wireless device 12 with a triggering offset 20 that has a value within the range of values indicated by the transmitted signaling 26 (Block 210).
In some embodiments, the method also comprises receiving, in a first slot 18-0, downlink control information 14 that triggers a set 16 of aperiodic CSI-RS resources (Block 220). The method may further comprise receiving, in a second slot 18-X, CSI-RS on the set 16 of aperiodic CSI-RS resources triggered by the received downlink control information 14 (Block 230). In one or more embodiments, the offset between the first slot 18-0 and the second slot 18-X has a value within the range of values indicated by the transmitted signaling 26.
In some embodiments, the method also comprises based on the triggering offset 20 configured by the received control message 22, operating in a sleep state between the first slot 18-0 and the second slot 18-X (Block 240).
Note that, in some embodiments where the signaling 26 indicates the range of values implicitly, the signaling 26 may actually indicate that the wireless device 12 supports cross-slot scheduling, where such support for cross-slot scheduling indicates that the wireless device 12 supports a certain range of values for the triggering offset 20, e.g., a range of 0 . . . 31 in accordance with the aperiodicTriggeringOffsetExt-r16 parameter.
In some embodiments, the method also comprises, based on the received signaling 26, configuring the wireless device 12 with a triggering offset 20 (Block 310).

In some embodiments, the offset between the first slot 18-0 and the second slot 18-X has a value within the range of values indicated by the received signaling 26.

Note that, as used herein, a transmission timing structure may comprise a plurality of symbols, and/or define an interval comprising several symbols (respectively their associated time intervals). In the context of this disclosure, it should be noted that a reference to a symbol for ease of reference may be interpreted to refer to the time domain projection or time interval or time component or duration or length in time of the symbol, unless it is clear from the context that the frequency domain component also has to be considered. Examples of transmission timing structures include slot, subframe, mini-slot (which also may be considered a substructure of a slot), slot aggregation (which may comprise a plurality of slots and may be considered a superstructure of a slot), respectively their time domain component. A transmission timing structure may generally comprise a plurality of symbols defining the time domain extension (e.g., interval or length or duration) of the transmission timing structure, and arranged neighboring to each other in a numbered sequence. A timing structure (which may also be considered or implemented as synchronisation structure) may be defined by a succession of such transmission timing structures, which may for example define a timing grid with symbols representing the smallest grid structures. A transmission timing structure, and/or a border symbol or a scheduled transmission may be determined or scheduled in relation to such a timing grid. A transmission timing structure of reception may be the transmission timing structure in which the scheduling control signaling is received, e.g. in relation to the timing grid. A transmission timing structure may in particular be a slot or subframe or in some cases, a mini-slot.
References to specific resource structures like transmission timing structure and/or symbol and/or slot and/or mini-slot and/or subcarrier and/or carrier may pertain to a specific numerology, which may be predefined and/or configured or configurable. A transmission timing structure may represent a time interval, which may cover one or more symbols. Some examples of a transmission timing structure are transmission time interval (TTI), subframe, slot and mini-slot. A slot may comprise a predetermined, e.g. predefined and/or configured or configurable, number of symbols, e.g. 6 or 7, or 12 or 14. A mini-slot may comprise a number of symbols (which may in particular be configurable or configured) smaller than the number of symbols of a slot, in particular 1, 2, 3 or 4 symbols. A transmission timing structure may cover a time interval of a specific length, which may be dependent on symbol time length and/or cyclic prefix used. A transmission timing structure may pertain to, and/or cover, a specific time interval in a time stream, e.g. synchronized for communication. Timing structures used and/or scheduled for transmission, e.g. slot and/or mini-slots, may be scheduled in relation to, and/or synchronized to, a timing structure provided and/or defined by other transmission timing structures. Such transmission timing structures may define a timing grid, e.g., with symbol time intervals within individual structures representing the smallest timing units. Such a timing grid may for example be defined by slots or subframes (wherein in some cases, subframes may be considered specific variants of slots). A transmission timing structure may have a duration (length in time) determined based on the durations of its symbols, possibly in addition to cyclic prefix/es used. The symbols of a transmission timing structure may have the same duration, or may in some variants have different duration. The number of symbols in a transmission timing structure may be predefined and/or configured or configurable, and/or be dependent on numerology. The timing of a mini-slot may generally be configured or configurable, in particular by the network and/or a network node. The timing may be configurable to start and/or end at any symbol of the transmission timing structure, in particular one or more slots.
In general, a numerology and/or subcarrier spacing may indicate the bandwidth (in frequency domain) of a subcarrier of a carrier, and/or the number of subcarriers in a carrier and/or the numbering of the subcarriers in a carrier. Different numerologies may in particular be different in the bandwidth of a subcarrier. In some variants, all the subcarriers in a carrier have the same bandwidth associated to them. The numerology and/or subcarrier spacing may be different between carriers in particular regarding the subcarrier bandwidth. A symbol time length, and/or a time length of a timing structure pertaining to a carrier may be dependent on the carrier frequency, and/or the subcarrier spacing and/or the numerology. In particular, different numerologies may have different symbol time lengths.
Signaling may generally comprise one or more symbols and/or signals and/or messages. A signal may comprise or represent one or more bits. An indication may represent signaling, and/or be implemented as a signal, or as a plurality of signals. One or more signals may be included in and/or represented by a message. Signaling, in particular control signaling, may comprise a plurality of signals and/or messages, which may be transmitted on different carriers and/or be associated to different signaling processes, e.g. representing and/or pertaining to one or more such processes and/or corresponding information. An indication may comprise signaling, and/or a plurality of signals and/or messages and/or may be comprised therein, which may be transmitted on different carriers and/or be associated to different acknowledgement signaling processes, e.g. representing and/or pertaining to one or more such processes. Signaling associated to a channel may be transmitted such that represents signaling and/or information for that channel, and/or that the signaling is interpreted by the transmitter and/or receiver to belong to that channel. Such signaling may generally comply with transmission parameters and/or format/s for the channel.
Signaling may generally be considered to represent an electromagnetic wave structure (e.g., over a time interval and frequency interval), which is intended to convey information to at least one specific or generic (e.g., anyone who might pick up the signaling) target. A process of signaling may comprise transmitting the signaling. Transmitting signaling, in particular control signaling or communication signaling may comprise encoding and/or modulating. Encoding and/or modulating may comprise error detection coding and/or forward error correction encoding and/or scrambling. Receiving control signaling may comprise corresponding decoding and/or demodulation. Error detection coding may comprise, and/or be based on, parity or checksum approaches, e.g. CRC (Cyclic Redundancy Check). Forward error correction coding may comprise and/or be based on for example turbo coding and/or Reed-Muller coding, and/or polar coding and/or LDPC coding (Low Density Parity Check). The type of coding used may be based on the channel (e.g., physical channel) the coded signal is associated to.
Example types of signaling comprise signaling of a specific communication direction, in particular, uplink signaling, downlink signaling, sidelink signaling, as well as reference signaling (e.g., SRS or CRS or CSI-RS), communication signaling, control signaling, and/or signaling associated to a specific channel like PUSCH, PDSCH, PUCCH, PDCCH, PSCCH, PSSCH, etc.).
Communication signaling may comprise, and/or represent, and/or be implemented as, data signaling, and/or user plane signaling. Communication signaling may be associated to a data channel, e.g. a physical downlink channel or physical uplink channel or physical sidelink channel, in particular a PDSCH (Physical Downlink Shared Channel) or PSSCH (Physical Sidelink Shared Channel). Generally, a data channel may be a shared channel or a dedicated channel. Data signaling may be signaling associated to and/or on a data channel.
An indication generally may explicitly and/or implicitly indicate the information it represents and/or indicates. Implicit indication may for example be based on position and/or resource used for transmission. Explicit indication may for example be based on a parametrization with one or more parameters, and/or one or more index or indices, and/or one or more bit patterns representing the information. It may in particular be considered that control signaling as described herein, based on the utilized resource sequence, implicitly indicates the control signaling type.
Additional embodiments will now be described. At least some of these embodiments may be described as applicable in certain contexts and/or wireless network types for illustrative purposes, but the embodiments are similarly applicable in other contexts and/or wireless network types not explicitly described.
In some embodiments, Channel State Information Reference Signals (CSI-RSs) are used for channel state feedback related to the use of transmission modes that enable UE-specific antenna precoding. These transmission modes use the UE-specific Demodulation Reference Symbols (DM-RSs) at the time of transmission with the precoding performed based on the feedback received from and measured by the UE on the CSI-RSs. The CSI-RS can be configured for a UE as Non-Zero-Power (NZP) and Zero-Power (ZP) instances. The NZP CSI-RS configuration indicates the resource elements (REs) where the cell being measured transmits CSI-RS and the ZP CSI-RS configuration indicates the REs where no information is transmitted by the cell being measured. The ZP CSI-RS REs are typically configured so that they overlap with transmissions from other cells which allows the UE to make interference measurements or Reference Signal Received Power (RSRP) measurements on the CSI-RS of other cells. Knowledge of the ZP CSI-RS configurations also allows the UE to not use these REs, i.e., rate-match around these REs when receiving the Physical Downlink Shared Channel (PDSCH).
In Rel-15, the A-CSI triggering offset value that can be configured is restricted to the set of values in {0, 1, 2, 3, 4, 16, 24} slots. For example, this RRC parameter can be aperiodicTriggeringOffset.
In Rel-16, a new RRC parameter is introduced for indicating a flexible A-CSI triggering offset value between 0 to 31 (in slots) i.e. with extended offset value range. For example, this RRC parameter can be aperiodicTriggeringOffsetExt-r16.
The Information Element (IE) NZP-CSI-RS-Resource is used to configure Non-Zero-Power (NZP) CSI-RS transmitted in the cell where the IE is included, which the UE may be configured to measure on.
The IE NZP-CSI-RS-Resourceld is used to identify one NZP-CSI-RS-Resource.
The IE NZP-CSI-RS-ResourceSet is a set of Non-Zero-Power (NZP) CSI-RS resources (their IDs) and set-specific parameters.
The IE NZP-CSI-RS-ResourceSetld is used to identify one NZP-CSI-RS-ResourceSet.
For a given NZP-CSI-RS resource set, a UE can be configured with a triggering offset value using one of the Rel-15 and Rel-16 parameters. An example TP update based on the above two parameters is as follows:
An example TP for RRC parameter name alignment is below (with bold underlined changes).
<Begin TP>
1.5.2.1.5.1 Aperiodic CSI Reporting/Aperiodic CSI-RS when the triggering PDCCH and the CSI-RS have the same numerology
When aperiodic CSI-RS is used with aperiodic reporting, the CSI-RS offset is configured per resource set by the higher layer parameter aperiodicTriggeringOffset or aperiodicTriggeringOffsetExt-r16. The CSI-RS triggering offset has the values of {0, 1, 2, 3, 4, 16, 24} slots. If the UE is not configured with [minimumSchedulingOffset] for any DL or UL bandwidth part (BWP) and if all the associated trigger states do not have the higher layer parameter qcl-Type set to ‘QCL-TypeD’ in the corresponding Transmission Configuration Indicator (TCI) states, the CSI-RS triggering offset is fixed to zero. The aperiodic triggering offset of the CSI Interference Measurement (CSI-IM) follows offset of the associated NZP CSI-RS for channel measurement.
2.5.2.1.5.1a Aperiodic CSI Reporting/Aperiodic CSI-RS when the triggering PDCCH and the CSI-RS have different numerologies
Aperiodic CSI-RS timing:
When the aperiodic CSI-RS is used with aperiodic CSI reporting, the CSI-RS triggering offset X is configured per resource set by the higher layer parameter aperiodicTriggeringOffset or aperiodicTriggeringOffsetExt-r16, including the case that the UE is not configured with [minimumSchedulingOffset] for any DL or UL BWP and all the associated trigger states do not have the higher layer parameter qcl-Type set to ‘QCL-TypeD’ in the corresponding TCI states. The CSI-RS triggering offset has the values of {0, 1, . . . , 31} slots when the PDCCH<μCSIRS and {0, 1, 2, 3, 4, 16, 24} when the μPDCCH>μCIRS. The aperiodic CSI-RS is transmitted in a slot
if UE is configured with ca-SlotOffset for at least one of the triggered and triggering cell, and
otherwise, and where
n is the slot containing the triggering DCI, Xis the CSI-RS triggering offset in the numerology of CSI-RS according to the higher layer parameter aperiodicTriggeringOffset or aperiodicTriggeringOffsetExt-r16,
μCSIRS and μPDCCH are the subcarrier spacing configurations for CSI-RS and PDCCH, respectively,
<End TP>
The use case for the extended offset value range may enable more efficient/flexible A-CSI triggering offset configuration for the case when a Physical Downlink Control Channel (PDCCH) on a first cell with a lower subcarrier spacing (SCS) schedules an A-CSI-RS transmission on a second cell with higher SCS.
Another use case for the extended offset value range is to enable more efficient/flexible A-CSI triggering offset configuration for the case when a UE supports cross-slot scheduling based power savings, wherein a minimum scheduling offset restriction is applied for PDSCH scheduling, and the same restriction is also applied for A-CSI-RS triggering offset. For example, if a minimum scheduling offset restriction is applicable (e.g. min K0=5), then UE will not expect to be scheduled using a DCI that indicates a Physical Downlink Shared Channel (PDSCH) scheduling offset of K0<5 and the UE will not expect to be scheduled using a DCI that indicates a A-CSI triggering offset smaller than 5. This can be applied for all cases including same-SCS scheduling (including same-carrier scheduling), high-SCS-PDCCH scheduling lower-SCS PDSCH/A-CSI-RS, and lower-SCS PDCCH scheduling higher-SCS PDSCH/A-CSI-RS.
The case where a UE indicates capability for support for configuration of the extended offset value range for A-CSI triggering offset will now be described, e.g., so as to illustrate various examples of signaling 26 in
In an embodiment, a UE indicating support for “Cross Slot Scheduling” also indicates the capability (e.g. implicitly or explicitly) to support the new RRC parameter (e.g. aperiodicTriggeringOffsetExt-r16.) and/or the extended offset value range for A-CSI triggering offset. For example, in the implicit case, support of extended offset value range for A-CSI triggering offset via aperiodicTriggeringOffsetExt-r16 can become a component within the capability to “Cross Slot Scheduling”.
In an embodiment, a UE indicates a separate capability to support the new RRC parameter (e.g. aperiodicTriggeringOffsetExt-r16.) and/or the extended offset value range for A-CSI triggering offset. For example, the capability can be separate from the capability indicating support for “Cross-carrier A-CSI RS triggering with different SCS” and/or “Cross slot scheduling”. For example, a new feature group may be introduced for this option.
In an embodiment, a UE indicating capability to “Cross-carrier A-CSI RS triggering with different SCS” also indicates the capability (e.g. implicitly or explicitly) to support the new RRC parameter (e.g. aperiodicTriggeringOffsetExt-r16.) and/or the extended offset value range for A-CSI triggering offset. For example, in the implicit case, support of extended offset value range for A-CSI triggering offset via aperiodicTriggeringOffsetExt-r16 can become a component within the capability to “Cross-carrier A-CSI RS triggering with different SCS”.
Cross-slot scheduling capability (e.g. 19-2) may have a component as follows:
minimumSchedulingOffset K2 configuration for PUSCH
Cross-carrier A-CSI RS triggering with different SCS capability (e.g. 18-6) may have a component as follows: Cross-carrier A-CSI RS triggering with different SCS.
As described in some of previous embodiments, an additional component as follows can be added to one or both of the above capabilities: support of extended offset value range for A-CSI triggering offset via aperiodicTriggeringOffsetExt-r16.
As described in one of previous embodiments, an additional new capability can be introduced “support of extended offset value range for A-CSI triggering offset” with the following component: support of extended offset value range for A-CSI triggering offset via aperiodicTriggeringOffsetExt-r16.
Note: the new capability can be independent of other capabilities e.g. 19-2 or 18-6.
A gNB upon receiving the UE capability signaling according to one of the above embodiments (e.g., as examples of signaling 26), can suitably configure the A-CSI triggering offset for the UE.
Since a UE indicates capability support of extended offset value range for A-CSI triggering offset, in one embodiment, the extended value range can be used regardless of whether the corresponding feature (Cross-carrier A-CSI-RS triggering with different SCS or Cross-slot scheduling) is enabled or not. The cases where it is configurable may be clear from 3GPP specifications already in some cases such as “The CSI-RS triggering offset has the values of {0, 1, . . . , 31} slots when the μPDCCH<μCSIRS”, where μ denotes the numerology corresponding to the SCS for control channel (PDCCH) and SCS for CSI-RS. μ=0,1,2,3, for 15 kHz, 30 kHz, 60 kHz, and 120 kHz, respectively.
However, in some cases such as UEs supporting cross-slot scheduling, it may not be so clear from the 3GPP specification. For the Cross-slot scheduling case, there may be some additional conditions added under which a UE may support the extended offset value range for A-CSI triggering offset via aperiodicTriggeringOffsetExt-r16.
The CSI-RS triggering offset with extended value range (e.g. of {0, 1, 2, 3, 4, 5, 6 . . . 15, 16, 24} slots) can be configured only for a DL BWP when the UE is configured with minimum scheduling offset (e.g. for DL) for the DL BWP.
In some cases, if a UE indicates support of the new RRC parameter (e.g. aperiodicTriggeringOffsetExt-r16.) and/or the extended offset value range for A-CSI triggering offset, the CSI-RS triggering offset with extended value range can be applied without any restrictions on configurability.

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., MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (e.g., E-SMLCs), and/or 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 660 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 660 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 660 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 680 for the different RATs) and some components may be reused (e.g., the same antenna 662 may be shared by the RATs).

The radio signal may then be transmitted via antenna 662.
Similarly, when receiving data, antenna 662 may collect radio signals which are then converted into digital data by radio front end circuitry 692.

Power source 686 and/or power circuitry 687 may be configured to provide power to the various components of network node 660 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). Power source 686 may either be included in, or external to, power circuitry 687 and/or network node 660. For example, network node 660 may be connectable to an external power source (e.g., an electricity outlet) via an input circuitry or interface such as an electrical cable, whereby the external power source supplies power to power circuitry 687. As a further example, power source 686 may comprise a source of power in the form of a battery or battery pack which is connected to, or integrated in, power circuitry 687.

As used herein, wireless device (WD) refers to a device capable, configured, arranged and/or operable to communicate wirelessly with network nodes and/or other wireless devices. Unless otherwise noted, the term WD may be used interchangeably herein with user equipment (UE). Communicating wirelessly may involve transmitting and/or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and/or other types of signals suitable for conveying information through air. In some embodiments, a WD may be configured to transmit and/or receive information without direct human interaction. For instance, a WD may be designed to transmit information to a network on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the network. Examples of a WD include, but are not limited to, a smart phone, a mobile phone, a cell phone, a voice over IP (VoIP) phone, a wireless local loop phone, a desktop computer, a personal digital assistant (PDA), a wireless cameras, a gaming console or device, a music storage device, a playback appliance, a wearable terminal device, a wireless endpoint, a mobile station, a tablet, a laptop, a laptop-embedded equipment (LEE), a laptop-mounted equipment (LME), a smart device, a wireless customer-premise equipment (CPE). a vehicle-mounted wireless terminal device, etc. A WD may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X) and may in this case be referred to as a D2D communication device. As yet another specific example, in an Internet of Things (IoT) scenario, a WD may represent a machine or other device that performs monitoring and/or measurements, and transmits the results of such monitoring and/or measurements to another WD and/or a network node. The WD may in this case be a machine-to-machine (M2M) device, which may in a 3GPP context be referred to as an MTC device. As one particular example, the WD may be a UE implementing the 3GPP narrow band internet of things (NB-IoT) standard. Particular examples of such machines or devices are sensors, metering devices such as power meters, industrial machinery, or home or personal appliances (e.g. refrigerators, televisions, etc.) personal wearables (e.g., watches, fitness trackers, etc.). In other scenarios, a WD may represent a vehicle or other equipment that is capable of monitoring and/or reporting on its operational status or other functions associated with its operation. A WD as described above may represent the endpoint of a wireless connection, in which case the device may be referred to as a wireless terminal. Furthermore, a WD as described above may be mobile, in which case it may also be referred to as a mobile device or a mobile terminal.
