Abstract: PUCCH carrier switching at a UE may include decoding an RRC configuration including a time-domain pattern indicating a reference cell and a target PUCCH cell for one or more PUCCH transmissions at a given point in time. The reference cell may include a reference cell slot numerology and the target PUCCH cell may include a target PUCCH cell slot numerology. A slot for PUCCH transmissions may be determined based on the reference cell slot numerology. The determined slot may be used for transmission of at least one of an SR, a CSI, and a HARQ-ACK. The determined slot of the reference cell may be mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource may be determined for performing a PUCCH transmission using the corresponding slot of the target PUCCH cell. The PUCCH resource determination may be based on a PUCCH configuration of the target PUCCH cell.

Abstract: A user equipment (UE) is configured to provide a power headroom report (PHR) to a network. The UE receives a physical uplink shared channel (PUSCH) configuration from a base station of the wireless network, wherein the PUSCH configuration includes a plurality of beams over which PUSCH repetitions should be transmitted, determines at least one power headroom report (PHR) based on a power control parameter set corresponding to at least one of the plurality of beams or PUSCH repetitions and transmits the at least one PHR to the base station.

Abstract: Disclosed are techniques for differentiating between licensed and unlicensed bands in a common portion of frequency spectrum to facilitate initial access in a fifth generation (5G) new radio (NR) wireless communication system having an NR node. The techniques include an NR generating and UE processing frequency configuration information indicating whether the common portion of frequency spectrum is allocated as a licensed band or an unlicensed band to enable a determination that the frequency spectrum is configured as the licensed band or unlicensed band and thereby facilitate initial access.

Abstract: A cell transmits synchronization signal blocks (SSB) to a user equipment (UE) for the UE to synchronize with the cell. The cell configures a discovery reference signal (DRS) window for synchronization signal block (SSB) transmission to a user equipment (UE), determines that a channel in an unlicensed spectrum is not occupied and transmits multiple SSBs to the UE in response to determining that the channel in the unlicensed spectrum is not occupied.

Abstract: A user equipment (UE), a base station (e.g., next generation NodeB (gNB)), or other network component can operate to configure multiple transmission reception point (mTRP) communication for new radio (NR) unlicensed (NR-U) standalone communications in a network. A processor or processing circuitry can acquire or share a channel occupancy time (COT) for a first transmission reception point (TRP). The COT can then be mediated with a UE or a second TRP via an ideal backhaul or an ideal backhaul based on a proximity condition. The COT can be shared between the first and second TRP via X2 signaling over an X2 interface.

Abstract: This disclosure relates to techniques for selecting time domain resources in a wireless communication system. A wireless device and a cellular base station may establish a wireless link. The wireless device may receive an uplink grant that provides multiple uplink transmission occasions. The wireless device may select a subset of the multiple uplink transmission occasions and may perform uplink transmissions during the selected subset. The subset selected by the wireless device may be determined based on a resource adjustment rule for the wireless device. Each of the uplink transmissions may include an indication of uplink transmission occasions that are unused by the wireless device.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to multiplex a first HARQ of a first priority and a second HARQ of a second priority to form an initial UCI payload. The UE can select a PUCCH resource accordingly to a PUCCH configuration, and generate a second UCI payload by removing or replacing at least a portion of the initial UCI payload when a size of the initial UCI payload is larger than a size of the PUCCH resource. The UE can encode at least a part of the second UCI payload including the first HARQ to generate an error correction code word. Afterwards, the UE can add the error correction code word to the second UCI payload to generate a transmission UCI payload, and transmit the transmission UCI payload to the base station.
