Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.

Abstract: Techniques are described herein for collision handling in uplink transmissions. A user equipment (UE) may have more information to transmit during an uplink transmission than the allocated resources can handle. The UE may identify that an uplink transmission includes a plurality of different channels. The UE may exclude service types or scale the transmit power of service types based on performing a prioritization of the different channels in the uplink transmission. In some cases, the UE may prioritize ultra-reliable low-latency communications (URLLC) service types over enhanced mobile broadband (eMBB) service types. In some cases, the content of the URLLC service types and the content of the eMBB service types may be considered when prioritizing. The UE may be capable of configuring different sets of priority rules based on reliability thresholds and latency thresholds associated with the service types.

Abstract: The apparatus configured to provide an enhanced power management solution, by configuring the UE to perform a Beam Failure Detection (BFD) procedure in view of the DRX configuration of the UE and a periodicity of reference signal(s) used to assess a radio link quality. The apparatus receives a DRX configuration having a DRX period comprising a DRX on duration and a DRX off duration. The apparatus then determines a beam failure indication period based on a periodicity for reference signals (RSs) configured for beam failure detection and a DRX period. Then, the apparatus performs a radio link quality measurement of at least one of the RSs based on the beam failure indication period determined by the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station (BS), a signaling communication that indicates one or more preamble sequence configurations. Each of the preamble sequence configurations may specify a respective plurality of preamble sequence rules for a different random access channel (RACH) procedure type. The UE may generate, based at least in part on a plurality of preamble sequence rules for a preamble sequence configuration of the one or more preamble sequence configurations, a preamble sequence for a RACH communication in a RACH procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may monitor, in a first bandwidth part, of a plurality of bandwidth parts, associated with a first monitoring periodicity and in a downlink control channel, for a downlink control information (DCI) message. The user equipment may selectively transition, based at least in part on the DCI message, from the first bandwidth part to a second bandwidth part, of the plurality of bandwidth parts, associated with a second monitoring periodicity that is less than the first monitoring periodicity. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to performing a random access procedure are provided. A first wireless communication device receives a random access response monitoring configuration for a plurality of random access opportunities associated with a random access attempt. The first wireless communication device transmits, to a second wireless communication device, one or more random access preambles associated with the plurality of random access opportunities. The first wireless communication device monitors for a random access response for each of the one or more random access preambles based on the random access response monitoring configuration.

Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently determining whether to transmit an uplink transmission scheduled by a semi-static grant or a dynamic uplink transmission scheduled by a dynamic grant when the dynamic uplink transmission conflicts with the uplink transmission scheduled by the semi-static grant. In particular, if a user equipment (UE) determines that a dynamic grant is received within a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the uplink transmission scheduled by the semi-static grant and refrain from transmitting the dynamic transmission. Alternatively, if the UE determines that a dynamic grant is received in advance of a threshold time before an uplink transmission scheduled by a semi-static grant, the UE may transmit the dynamic transmission and refrain from transmitting the uplink transmission scheduled by the semi-static grant.

Abstract: In some aspects, a user equipment (UE) determines a transmission gap adjustment (TGA) for a first message (msgA) of a 2 step random access channel (RACH) procedure based on measurement of a reference signal transmitted by a base station as well as the radio resource configuration (RRC) configurations for msgA. In other aspects, a base station transmits a system information block (SIB) or RRC signaling that indicates at least one possible configuration of the TGA, and UEs determine the TGA depending on RRC state. Connected mode UEs having a timing alignment (TA) timer running may determine the TGA based on a previous TA. UEs in other RRC modes determine the TGA based on the possible configuration transmitted in the SIB or RRC signaling. Advantageously, 2 step RACH UEs are able to communicate with the base station without the closed loop TA information provided by a 4 step RACH.
