Abstract: Aspects presented herein may enable a network entity, such as a base station or a component of a base station, to indicate a PUCCH repetition factor to a set of UEs via group-common DCI. In one aspect, a network entity transmits, to a set of UEs, an indication associated with a number of PUCCH retransmissions via group-common DCI. The network entity receives, from one or more UEs in the set of UEs, one or more PUCCH retransmissions based on the transmitted indication. In another aspect, a UE receives, from a network entity, an indication associated with a number of PUCCH retransmissions via group-common DCI. The UE transmits, to the network entity, one or more PUCCH retransmissions based on the received indication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may support communicating uplink control messages over a physical uplink control channel (PUCCH) using a time domain waveform. For example, the base station may configure the UE with a first group of PUCCH resource sets associated with a first type of time domain waveform and a second group of PUCCH resource sets associated with a second type of time domain waveform. The base station may transmit downlink control information (DCI) to the UE that indicates a type of time domain waveform and a PUCCH resource of a PUCCH resource set. In response, the UE may select the PUCCH resource set from either the first group or the second group and may transmit an uplink control message using the indicated PUCCH resource and type of time domain waveform.

Abstract: Aspects relate to configuration of phase-tracking reference signals (PT-RSs) in sidelink networks. A sidelink PT-RS configuration for a transmitting wireless communication device may be configured based on a sidelink channel state information (CSI) report received from a receiving wireless communication device. The transmitting wireless communication device may further transmit the sidelink PT-RS configuration to the receiving wireless communication device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to generate a set of data packets that are to be transmitted to a base station, where each data packet of the set of data packets is associated with a respective packet expiration time. The UE may transmit an indication of packet expiration information associated with the set of data packets, where the packet expiration information is based on a set of packet expiration times associated with the set of data packets. The UE may receive, from the base station, scheduling information associated with at least a subset of the set of data packets, where the scheduling information is based on the packet expiration information. The UE may then transmit at least one data packet of the subset data packets to the base station in accordance with the scheduling information.

Abstract: In accordance with some embodiments, wireless communication for transmission of a beam failure recovery (BFR) MAC-CE is disclosed. A method performed on a user equipment (UE) includes detecting a beam failure of at least one beam of a beam group. The method further comprises triggering a BFR in response to the detection of the beam failure of the at least one beam of the beam group. In addition, the method includes generating a BFR medium access control-control element (MAC-CE) that includes BFR information associated with the beam group. Further, the method comprises transmitting the BFR MAC-CE that includes the BFR information associated with the beam group using a transmission resource.
