Abstract: Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

Abstract: A user equipment (UE) is configured to received phase tracking-reference signals (PT-RS). The UE receives configuration information associated with inserting phase tracking-reference signals (PT-RS) into a physical uplink control channel (PUCCH) signal, generates a first signal that is to be transmitted over the PUCCH and is configured to include one or more PT-RS and transmits the first signal over the PUCCH. The UE may also generate a second signal that is to be transmitted over the PUSCH and is configured to include one or more PT-RS, wherein the configuration information further comprises configuration information associated with inserting PT-RS into a physical uplink control (PUSCH) signal and transmit the second signal over the PUSCH, wherein the PUCCH and PUSCH transmissions are performed simultaneously over different component carriers (CCs).

Abstract: Systems and methods disclosed herein relate to acknowledgement signaling sent by a user equipment (UE) in response to downlink control information (DCI) received from a base station that schedules the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH). Acknowledgement signaling may inform the base station that DCI scheduling the multi-PUSCH/multi-PDSCH was received (or not), so that the base station may reclaim those scheduled resources in the case that the UE remains unaware of them. Methods for performing this signaling include, e.g., the use of HARQ-ACK codebooks (whether in a semi-static or dynamic manner), and aperiodic sounding reference signals (A-SRS). Embodiments involving such DCI received across multiple component carriers of different serving cells of the UE are contemplated. Acknowledgment signaling according to multi-PUSCH/multi-PDSCH subgroups, monitoring windows, acknowledgment signaling enablement/disablement, and the use of DCI to trigger acknowledgment signaling are also discussed.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing mechanisms for performing L1-RSRP (Layer 1 Reference Signal Received Power) measurements and/or L1-SINR (Layer 1 Signal-to-Noise and Interference Ratio) measurements on a neighbor cell. For example, some aspects of this disclosure relate to an electronic device. The electronic device includes a transceiver configured to communicate with a serving cell and a neighbor cell and a processor communicatively coupled to the transceiver. The processor determines a measurement period for a Layer 1 (L1) measurement on the neighbor cell and receives, using the transceiver, a resource from the neighbor cell during the measurement period. The processor further performs the L1 measurement on the neighbor cell using the received resource from the neighbor cell.

Abstract: A user equipment (UE) is configured to receive synchronization signal blocks (SSBs) from a wireless network to estimate frequency and timing errors. The UE receives a quasi co-location (QCL) configuration between a synchronization signal block (SSB) and at least one of a further SSB or a tracking reference signal (TRS), receives the SSB and the at least one of the further SSB or the TRS and estimates a frequency and timing error for the SSB by combining, based on the QCL configuration, measurements for the SSB and measurements for the at least one of the further SSB or the TRS.

Abstract: Described are approaches to multi-cell PUSCH/PDSCH scheduling with a single DCI (downlink control information) in a wireless communication system. In one approach, only one component carrier is configured with the multi-cell scheduling DCIs, with no DCI configured on the other component carriers. In a second approach, all of the component carriers can be configured with the multi-cell scheduling DCIs. In a third option, one component carrier is configured with multi-cell scheduling DCI only, while the other component carriers can be configured with the legacy single-cell scheduling DCIs. In a fourth option, one component carrier is configured with both multi-cell scheduling DCIs and the legacy single-cell scheduling DCIs, while the other component carriers can be configured with the legacy single-cell scheduling DCIs. In the fifth option, all the component carriers can be configured with both multi-cell scheduling DCIs and the legacy single-cell scheduling DCIs. In addition, dropping rules are described for the situations of overbooking, i.e., when the number of PDCCH candidates exceeds the capabilities of the user equipment (UE). Potential dropping rules include following the legacy procedure, and providing higher priority to candidates with user-specific search spaces with multi-cell scheduling DCIs. Also described is the impact on DCI formats to accommodate single-cell and multi-cell scheduling DCIs on the same component carrier. Finally, limits on the number and sizes of the DCIs are described.
