Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may identify a configuration for one or more repetitions of an uplink control channel transmission, where each repetition of the one or more repetitions including a first quantity of symbols indicated by the configuration. The UE may determine a quantity of resource blocks for each repetition of the one or more repetitions. The UE may then identify that a second quantity of symbols is available to the UE to transmit a repetition of the one or more repetitions, and the second quantity of symbols may be less than the first quantity of symbols. The UE may transmit, to a base station, the repetition on the second quantity of symbols using the quantity of resource blocks for each repetition with the first quantity of symbols.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a configuration of a retransmission of a first message of a random access procedure based on a set of transmission configuration options transmitted by a base station. For example, the UE may transmit the first message but may reconfigure the first message for the retransmission based on the transmission configuration options. Additionally, the UE may configure a set of transmission configuration states based on the transmission configuration options for transmitting/retransmitting the first message. In some cases, the UE may determine to switch transmission configuration states based on a trigger signaled by the base station and/or a determination by the UE. Additionally, the UE may transmit an indication of a log of state transitions performed prior to a retransmission of the first message to facilitate combining of the retransmissions at the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select an uplink transmission power sharing configuration to use for transmission of one or more uplink messages. The uplink transmission power sharing configuration may be based on a first uplink transmission power capability of a first radio frequency (RF) chain of the UE and on a second uplink transmission power capability of a second RF chain of the UE. The UE may transmit the one or more uplink messages to a network entity in accordance with the uplink transmission power sharing configuration. Specifically, the UE may transmit the one or more uplink messages via the first RF chain using a first transmission power, and may transmit the one or more uplink messages via the second RF chain using a second transmission power that is different from the first transmission power.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.

Abstract: User equipments (UEs) with reduced capabilities may need a relaxed processing timeline relative to standard UEs. The relaxed processing timeline may provide UEs with reduced capabilities an appropriate amount of time (e.g., during a random access procedure) to decode messages from a base station (BS) and/or to prepare uplink messages. Aspects of the disclosure relate to a UE configured to transmit a message to a serving BS, the message including a request for timeline relaxation for transmission of a subsequent message, the message and the subsequent message being associated with a random access procedure. The UE may receive a response message associated with the random access procedure and indicating one or more timing offsets corresponding to the timeline relaxation. The UE may transmit the subsequent message to the serving BS based on the one or more timing offsets indicated by the serving BS. The subsequent message acknowledges the response message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, when operating in a multiple link communication system, one or more downlink control information (DCI) messages scheduling one or more downlink communications. The user equipment may determine, based at least in part on the one or more DCI messages, whether a communication constraint is satisfied for the one or more downlink communications. The user equipment may determine a communication configuration for the one or more downlink communications based at least in part on whether the communication constraint is satisfied. The user equipment may receive, in the multiple link communication system, the one or more downlink communications based at least in part on the communication configuration. Numerous other aspects are provided.

Abstract: A low complexity user equipment (UE) may be in communication with another UE (e.g., with a premium UE or more capable UE) via a device-to-device communication link (e.g., via sidelink), and the low complexity UE may leverage the device-to-device link to improve (e.g., simplify, expedite, etc.) random access procedures performed by the low complexity UE. For example, a low complexity UE may request contention free random access (CFRA) resources via the device-to-device link with another UE. Another device (e.g., another UE in device-to-device communication with the low complexity UE) may receive the request from the low complexity UE and forward the request to the network (e.g., to a base station). The network may then configure CFRA resources for the low complexity UE. Upon receiving the CFRA configuration, the low complexity UE may perform a random access procedure (e.g., a CFRA procedure) with the network (e.g., with the base station) accordingly.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor multiple synchronization signal resources, each synchronization signal resource associated with a beam of a set of beams and may determine that multiple candidate beams of the set of beams satisfy a channel quality threshold. The UE may transmit an indication that the multiple candidate beams satisfy the channel quality threshold. For example, the UE may transmit a single random access message on a physical random access channel (PRACH) resource associated with multiple candidate beams, or may transmit multiple random access messages, each one on a different PRACH resource associated with a different candidate beam. The UE may receive an indication of one of the candidate beams from the base station and may establish a connection with the base station using the indicated candidate beam.

Abstract: Disclosed are techniques for reducing the overhead of low layer positioning reports. In an aspect, a user equipment (UE) performs at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from at least one transmission-reception point (TRP) during a positioning session, and reports, to a positioning entity via low layer signaling, a relative value of the at least one positioning measurement relative to an expected value of the at least one positioning measurement, wherein the relative value of the at least one positioning measurement is a difference between the expected value of the at least one positioning measurement and a measured value of the at least one positioning measurement.
