Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Certain aspects of the present disclosure provide techniques for handling collisions between PUSCH and sounding reference signal (SRS) on additional SRS symbols in an uplink subframe using carrier aggregation. The techniques provide rules that a user equipment (UE) may apply to decide if and when to drop or apply power scaling to SRS or PUSCH transmissions scheduled on overlapping time resources.

Abstract: Certain aspects of the present disclosure provide apparatus and method for wireless communication. For example, the method generally includes receiving signaling indicating a first subframe configuration, the first subframe configuration corresponding to a subframe with a first number of symbols in an uplink pilot time slot (UpPTS), receiving signaling indicating a second configuration, the second configuration indicating a second number of symbols in the UpPTS, generating a frame comprising the UpPTS having the first number of symbols corresponding to the first subframe configuration, the UpPTS including one or more SRSs corresponding to the second configuration, and transmitting the frame comprising the UpPTS.

Abstract: Aspects directed towards wake-up signal (WUS) scrambling sequence design are disclosed. In one example, a time-based scrambling sequence that facilitates a phase shift in time may be generated according to a time parameter associated with a WUS or a paging occasion (PO). A scrambled WUS may be generated by multiplying a WUS base sequence by the time-based scrambling sequence, and subsequently transmitted to at least one scheduled entity. In another example, a scrambled WUS may be received from a scheduling entity. A time-based scrambling sequence associated with the WUS may be identified in which the time-based scrambling sequence facilitates a phase shift in time and corresponds to a time parameter associated with a WUS or a PO. The WUS may be descrambled according to the time-based scrambling sequence. Other aspects, embodiments, and features are also included.

Abstract: Some techniques and apparatuses, described herein, provide for resource allocation to achieve frequency diversity, time diversity, and/or spatial diversity for wakeup signals destined to two or more UE groups by transmitting the wakeup signals according to respective resource patterns associated with the two or more UE groups. Additionally, some techniques and apparatuses described herein provide for resource allocation to achieve spatial diversity for wakeup signals for a single UE group by transmitting the wakeup signals using two or more antenna ports according to respective resource patterns associated with the two or more antenna ports. Furthermore, some techniques and apparatuses described herein provide configurations for wakeup signals based at least in part on delays or gaps, repetitious communications, synchronization in accordance with a power level of the wakeup signal, and the like.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit DCIs to a UE to schedule instances of one or more MBS TBs, the multiple instances of the one or more TBs being time-interleaved. For example, the network entity may transmit a first set of DCIs scheduling a first set of instances of a first TB, and a second set of DCIs scheduling a second set of instances of a second TB, where at least one instance of the first set of instances may be interleaved with the second set of instances. In some cases, the first and second set of DCIs may include one DCI to schedule the respective set of instances, or one DCI per instance of the respective set of instances. Additionally, or alternatively, the network entity may indicate one or more parameters to the UE associated with MBS inter-TB time interleaving.
