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: Performing user equipment (UE) coordination based beam management may include determining resources for measuring beams and reporting measured beam information. The resources may be configured for a first user equipment (UE) of a plurality of coordinated UEs. The determined resources may be transmitted to the first UE via radio resource control (RRC) or medium access control-control element (MAC CE). Measured beam information received from the first UE for configuring beam sharing between multiple UEs of the plurality of coordinated UEs may be decoded.

Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, a user equipment (UE) may receive a downlink (DL) scheduling command to schedule a DL data transmission from a base station. The UE may identify a scheduled slot for transmission of hybrid automatic repeat request (HARQ) feedback corresponding to the DL data transmission based on a received slot of the DL data transmission and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified from a value set based on an indicator comprised in the DL scheduling command, or may be identified using the various other techniques described herein.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

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.
