Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, receiving, from a base station, one or more configurations for a physical random access channel (PRACH) communication, and transmitting a PRACH communication according to a configuration selected from the one or more configurations based at least in part on the PRACH communication being subject to a maximum permissible exposure (MPE) condition and a rule. The rule may include a parameter that is received from the base station. Numerous other aspects are provided.

Abstract: In certain aspects, a method for wireless communication at a user equipment (UE) includes attempting to receive, from a first base station, data via a first communication link, generating a radio link control (RLC) status report indicating a status of the data at the UE, and transmitting, to a second base station, the RLC status report via a second communication link. The UE may be simultaneously connected to the first base station and the second base station using dual connectivity. In one example, the first base station may be configured as a secondary cell group (SCG) and the second base station may be configured as a master cell group (MCG). In one example, the first communication link may be a New Radio (NR) link and the second communication link may be a Long-Term Evolution (LTE) link.

Abstract: A first apparatus may be implemented as a user equipment (UE) or a component thereof. The first apparatus may be configured to receive a pre-grant message from a base station on a wireless channel. The first apparatus may be further configured to determine an interference level associated with the wireless channel. The first apparatus may then indicate the interference level to the base station in response to the pre-grant message. A second apparatus may be implemented as a base station or a component thereof. The second apparatus may be configured to transmit a pre-grant message to a UE on a wireless channel. The second apparatus may be further configured to detect for an acknowledgement (ACK) message responsive to the pre-grant message from the UE. The second apparatus may then determine an interference level associated with the wireless channel proximate to the UE based on detecting for the ACK message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a message type for a random access message associated with a two-step random access channel procedure. The message type may be either a first message type or a second message type that is different from the second message type. The message type may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The user equipment may transmit the random access message based at least in part on the determined message type. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for configuring device-to-device (D2D) communication in new radio (NR) for one or more user equipments (UEs). Specifically, features of the present disclosure provide techniques for initial beam-pairing for sidelink communication that optimize communication resources (e.g., resource pools) by indicating the direction of traffic (e.g., transmit or receive) during the initial beam-pairing procedure and to establish sidelink communication without the need for scheduling request transmissions between the UEs.

Abstract: Some aspects provide a method for wireless communication by a first wireless device. The method generally includes transmitting control information regarding at least one of scheduling or configuration of a channel state information (CSI) report to be transmitted by the first wireless device. The method generally includes generating the CSI report based on one or more CSI reference signals (CSI-RSs) received by the first wireless device. The method generally includes and transmitting the CSI report in accordance with the control information.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus methods and apparatus for multiplexing demodulation reference signals (DMRS) and synchronization signals (SS) in new radio (NR). An exemplary method that may be performed by a base station (BS) includes determining transmission resources, in a set of slots, to be used for first demodulation reference signals (DMRS), based on whether synchronization signals (SS) are to be transmitted in the set of slots, and transmitting the first DMRS using the transmission resources in the set of slots.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a first sidelink communication. The UE may generate a transmit power control command based at least in part on a signal to interference noise ratio measurement associated with the first sidelink communication. The UE may transmit, to control a transmit power for a second sidelink communication, the transmit power control command to the source UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a transmit power control (TPC) command that is based at least in part on a scheduled transmission of a sidelink communication. The UE may determine, based at least in part on refraining from transmitting the sidelink communication or transmitting the sidelink communication at a power that is lower than a power configured for the scheduled transmission of the sidelink communication, whether to adjust a transmit power of the UE based at least in part on the TPC command. The UE may selectively adjust the transmit power of the UE based at least in part on determining whether to adjust the transmit power. Numerous other aspects are provided.
