摘要： This disclosure relates to techniques for providing access control for multicast or broadcast (MC/BC) services. A base station broadcasts one or more cell barring parameters to a group of user equipment (UEs) that indicate whether the UEs of the group of UEs is permitted to select the cell of the base station for receiving the MC/BC services. The base station also broadcasts one or more access control parameters to a set of one or more UEs, of the group of UEs, that are indicated to be permitted to select the cell for receiving the MC/BC services based on the one or more cell barring parameters. The one or more access control parameters indicate whether the set of one or more UEs is permitted to establish or resume the RRC connected state with the base station for receiving the MC/BC services.

摘要： The present disclosure relates to methods and devices for flexible resource allocation. In one aspect, a base station can generate a narrowband data channel including a plurality of resource blocks (RBs). The base station may shift a position of the RBs of the narrowband data channel to align with a wideband resource block group (RBG) boundary. The base station can also adjust a precoding resource block group (PRG) for the narrowband data channel. Also, the base station can transmit the narrowband data channel to a User Equipment (UE) based on adjusting the PRG. In another aspect, the base station may align a beginning or last RB of the plurality of RBs with the wideband RBG boundary and/or align a beginning or last RB of the PRG with the wideband RBG boundary. In another aspect, the base station may transmit an indication to the UE indicating a flexible resource allocation.

摘要： A method, an apparatus, a base station, a user equipment, and a computer program product for wireless communication are provided. The base station may configure resource allocation for wakeup signaling based at least in part on one or more resource patterns corresponding to different user equipment groups and/or antenna port configurations. The user equipment may receive a wakeup signal based at least in part on the resource allocation, detect the wakeup signal based at least in part on a preamble of the wakeup signal, and receive a subsequent communication based at least in part on the wakeup signal. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for an orthogonal frequency division (OFDM) symbol that includes one or more cell-specific reference signal (CRS) resource elements and one or more narrowband physical downlink shared channel (NPDSCH) resource elements, an NPDSCH energy per resource element (EPRE), wherein the NPDSCH EPRE for the OFDM symbol is based at least in part on an EPRE differential between a narrowband reference signal (NRS) EPRE and a CRS EPRE. The UE may demodulate the OFDM symbol based at least in part on the NPDSCH EPRE. Numerous other aspects are provided.

摘要： Certain aspects of the present disclosure provide techniques for sounding reference signal (SRS) frequency hopping enhancements. An example method performed by user equipment generally includes determining a first sounding reference signal (SRS) frequency hopping pattern for transmitting one or more SRSs; determining an antenna switch will occur during the transmission of the one or more SRSs; determining a second SRS frequency hopping pattern for transmitting the one or more SRSs, wherein determining the second SRS frequency hopping pattern comprises using the first SRS frequency hopping pattern to generate the second SRS frequency hopping pattern based on the determined antenna switch; and transmitting a first set of SRSs of the one or more SRSs according to the first SRS frequency hopping pattern and transmitting a second set of SRSs of the one or more SRSs according to the second SRS frequency hopping pattern.

摘要： A method, an apparatus, and a computer program product for wireless communication are provided. Aspects described herein provide techniques and apparatuses associated with synchronizing a preconfigured uplink resource (PUR) release counter between a base station and a user equipment (UE). For example, the synchronization may be performed in connection with the UE entering a connected mode, the base station reconfiguring a PUR, and/or the like. By synchronizing the PUR release counter, misalignment of the PUR release counter between the UE and the base station may be reduced or eliminated. Reducing the misalignment of the PUR release counter reduces the occurrence of a premature release of a PUR, thus reducing UE interference and improving the likelihood of success of the UE's transmission.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit an indication of one or more beams for simultaneous unicast and multicast monitoring and receive, using the one or more beams, at least one of unicast traffic or multicast traffic. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that identifies one or more narrowband channels in which the UE is to receive one or more physical downlink shared channel (PDSCH) repetitions of a paging message associated with a discontinuous reception procedure. The UE may receive, in an online mode of the UE, one or more machine-type communication physical downlink control channel (MPDCCH) repetitions of control information. The UE may receive, in the online mode of the UE, the one or more PDSCH repetitions in the one or more narrowband channels identified by the configuration. The UE may process, in an offline mode of the UE, the one or more MPDCCH repetitions and the one or more PDSCH repetitions. Numerous other aspects are provided.

摘要： In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain measurements related to a plurality of reference signals received by the UE. In some aspects, each of the plurality of reference signals is associated with a different set of quasi co-location (QCL) properties. The UE may determine a QCL property based at least in part on the measurements related to the plurality of reference signals. The UE may determine, based at least in part on the determined QCL property, a QCL relationship among the plurality of reference signals and a physical downlink shared channel (PDSCH). The UE may receive the PDSCH based at least in part on the QCL relationship. Numerous other aspects are provided.
