Abstract: A user equipment (UE) performs capability exchange for indicating support of cross physical uplink control channel (PUCCH) group channel state information (CSI) reporting. In some embodiments, the UE receives a request from a network for the UE capability exchange and reports to the network whether cross PUCCH group CSI reporting is supported. The UE may also indicate whether a processing timeline for CSI reporting is to be relaxed to accommodate the cross PUCCH group CSI measurement and reporting.

Abstract: Disclosed is a user equipment (UE) configured to perform beam failure recovery with uplink antenna panel selection. In some embodiments, the UE determines a first UE antenna panel corresponding to a candidate beam detection (CBD) reference signal (RS); reports to a gNB a beam failure recovery request (BFRQ), the BFRQ including UE antenna panel information for the first UE antenna panel; and after receiving from the gNB a response to the BFRQ, changes from a second UE antenna panel to the first UE antenna panel and corresponding configuration for uplink transmission.

Abstract: Approaches are described that enhance the reliability of physical downlink control channel (PDCCH) detection where the PDCCH can be transmitted repeatedly with different beams. The approaches use soft combining where the user equipment (UE) combines the soft bits from each repetition, with the combined soft bits used to jointly decode the PDCCH repetitions. To support the soft combining, the UE needs to buffer the soft bits. Buffering approaches include determining what contributes towards the buffering, including scenarios where one of the linked search sets (SSs) is dropped, what is contributed in a linked SS set pair, how the duration of buffer counting is determined, and how the UE reports its maximum buffer size capability. In scenarios where the required buffer size exceeds the UE maximum buffer size, a priority rule may be used in the PDCCH decoding using the SS sets pair, where the priority is based on the SS type, the serving cell index, the SS set ID and/or the control channel resource set (CORESET) ID.

Abstract: Apparatuses, systems, and methods for SRS collision handling. A wireless device may determine whether simultaneous transmission of at least two sounding reference signals (SRSs) is allowed; if it is determined that the simultaneous transmission of the at least two SRSs is allowed, transmit the at least two SRSs simultaneously; and if it is determined that the simultaneous transmission of the at least two SRSs is not allowed, transmit one SRS of the at least two SRSs, and drop the other SRS of the at least two SRSs.

Abstract: Apparatuses, systems, and methods for a wakeup radio in a wireless communication system, e.g., in 5G NR systems and beyond. An RRC state is introduced to support a wakeup radio/, including defining transition mechanisms to/from existing RRC states. Further, signaling is introduced to activate a wakeup radio/activate an RRC low power state. Additionally, a bandwidth part framework for a wakeup signal is defined in which a base station may configure one or more time/frequency resources or a wakeup signal for a wakeup radio. In addition, various mechanisms are introduced to switch a wakeup radio on as well as to switch a wakeup radio off. Also, mechanisms are introduced for multiplexing multiple wakeup signals in a time/frequency resource, configuring a wakeup signal bandwidth, and configuring which beam a wakeup signal may be received on.
