Abstract: A user equipment (UE) is configured to configured to use multiple beams for transmission or reception. The UE receives, from a base station, at least one medium access control (MAC) control element (CE) that indicates multiple activated transmission configuration indicator (TCI) states, receives, from the base station, at least one downlink control information (DCI) indicating a subset of TCI states of the multiple activated TCI states, wherein the MAC CE and the DCI are part of a TCI configuration, and wherein the subset of TCI states corresponds to multiple transmission and reception points (TRPs) of a wireless network, maps the subset of TCI states to the corresponding multiple TRPs based on the TCI configuration and selects a beam used for transmission or reception based on one mapped TCI state of the mapped subset of TCI states.

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: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for reducing interferences for Sounding Reference Signal (SRS) by, for example, one or more of frequency domain interference randomization, code domain interference randomization, or power control. For example, a user equipment (UE) can be configured to determine a comb offset and/or a cyclic shift for each Sounding Reference Signal (SRS) transmission occasion for the UE. The comb offset and/or the cyclic shift change between different SRS transmission occasions of the UE. The UE is further configured to transmit an SRS to the base station using the determined comb offset and/or the determined cyclic shift during the SRS transmission occasion corresponding.

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: Mechanisms are provided for a user equipment (UE) to receive physical downlink shared channel (PDSCH) transmissions of a transport block (TB) over multiple slots. The UE can receive a configuration for a PDSCH transmission of a TB over multiple slots (TBoMS), such as a first number of slots, through a downlink from a base station. The configuration can include an indication of the first number of slots. The UE can further determine a transport block size (TBS) for the PDSCH transmission, and allocate a second number of slots used by the UE to support the PDSCH transmission. Based on the TBS for the PDSCH transmission satisfying a condition, the processor can be configured to receive the PDSCH transmission of the TB over the second number of slots, and decode the PDSCH transmission received.
