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 retransmit 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: Aspects described herein relate to receiving a configuration indicating multiple association rules associating random access preambles and payload formats, selecting, as part of a random access procedure, a random access preamble from the random access preambles for transmitting over a random access occasion, determining, based at least in part on at least one of the association rules in the configuration, a payload format associated with the random access preamble and a corresponding payload resource unit, and transmitting the random access preamble over the random access occasion and, according to the payload format, an associated payload over the corresponding payload resource unit. Multiplexing of payload resource units with same or different payload formats can be performed in time, frequency and code domains, based on the received configuration.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) receiving a configuration message from a base station for supporting random access channel (RACH) type selection by the UE. The configuration message may include one or more reference signals and one or more link quality thresholds corresponding to the one or more reference signals. The UE may generate measurements of the reference signals and determine link quality for communications between the UE and the base station based on the measurements. Based on a comparison between the link quality to corresponding link quality thresholds, the UE may select a two-step random access procedure, a four-step random access procedure, or both for establishing a connection with the base station. In some cases, the UE considers system loading information, transmission parameters, or random access rules in selecting the 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: 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 (UE) may select a first communication, associated with a first traffic type, or a second communication, associated with a second traffic type, as a selected communication for transmission in an overlapping resource, wherein the first communication and the second communication at least partially overlap in time, and wherein the selection is performed based at least in part on a rule; and transmit the selected communication. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a random backoff procedure in a wireless communication network such as a new radio (NR) network. A method for wireless communications that can be performed by a user equipment (UE) is provided. The method includes sending a random access preamble to a base station (BS) during a random access procedure. The method includes receiving a random access response from the BS including a backoff indicator. The method includes determining whether to send a contention-free random access (CFRA) preamble to the BS during the backoff period based, at least in part, on a type of the random access procedure.
