Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.

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, an indication that a plurality of physical downlink shared channel (PDSCH) communications are associated for purposes of demodulation reference signal bundling. The UE may determine whether a phase continuity is to be maintained for the plurality of PDSCH communications based at least in part on respective quasi-co-location assumptions for the plurality of PDSCH communications. The UE may process the plurality of PDSCH communications based at least in part on whether the phase continuity is to be maintained Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, control signaling identifying a first set of resources for data transmissions and a second set of resources for uplink control information (UCI) transmission by the UE when the UE is in an inactive state or an idle state. The UE may generate, when the UE is in one of the inactive state or the idle state, a UCI message based on the second set of resources. The UE may then transmit, to the base station when the UE in the one of the inactive state or the idle state, a data message on at least a portion of the first set of resources and the UCI message on the second set of resources.

Abstract: Wireless communications systems and methods related to the timing arrangements and the transmission gap configurations in 2-step random access channel (RACH) procedures to improve system latency and reliability of a RACH HARQ process are provided. The UE transmits a first message including a random access preamble and a payload, and then monitors for a second message in response to the first message during a random access response (RAR) window. In response to determining that no second message is received by the UE from the BS or a back off indicator is received within the RAR window, the UE re-transmits the preamble and payload of the first message after the RAR window lapses. In response to determining if the second message received within the RAR window carries a FallbackRAR or SuccessRAR, the UE then determines to re-transmit the payload of the first message based on the FallbackRAR, or to transmit an acknowledgement message based on the SuccessRAR.

Abstract: Wireless communication devices, systems, and methods related to power saving, including during connected mode operation and for extended reality (XR) data communications with or without discontinuous reception (DRX), are provided. For example, a method of wireless communication includes receiving, while in a connected mode, a configuration based on data traffic for the wireless communication device, the configuration indicating: a first zone associated with a first set of operating parameters for the wireless communication device; and a second zone associated with a second set of operating parameters for the wireless communication device, the second set of operating parameters being different than the first set of operating parameters; operating in the first zone with the first set of operating parameters to monitor for a first downlink communication signal; and operating in the second zone with the second set of operating parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a payload for inclusion in an uplink transmission. The UE may organize the payload into a code block group (CBG) that includes one or more code blocks (CB). The UE may map each CB of the CBG to a corresponding uplink shared channel resource unit (e.g., a physical uplink shared channel resource unit) of an uplink transmission occasion of the first UE. The uplink transmission occasion may also be shared with one or more additional UEs such that the CBG of the first UE is multiplexed with additional CBGs from the additional UEs. The UE may transmit, to a base station, the uplink transmission including each uplink shared channel resource unit on which the CBG is organized.

Abstract: Methods, systems, and devices for wireless communications are described for a two-step random access channel (RACH) procedure in which uplink random access preamble and message transmission occasions may span multiple transmission slots. Reference signal resources for transmitting a reference signal with a first random access message of the two-step RACH procedure may include at least one symbol in each of the multiple transmission slots. The reference signal resources, reference signal sequence, or both, may be identified based on a particular uplink random access message transmission occasion, random access preamble transmission occasion, random access preamble sequence configuration, or any combinations thereof.

Abstract: A random access configuration information based on a reference SCS may allow for a unified coordinate system used by the base station and UEs that describes the time-frequency resource configuration for a two-step RACH procedure. The apparatus receives, from a base station, random access configuration information for the base station. The apparatus determines a first time duration for a preamble of a first random access message based on the random access configuration information received from the base station and a reference SCS associated with an uplink BWP configured for the first random access message. The apparatus determines a second time duration for a payload of the first random access message based on the random access configuration information received from the base station and the reference SCS. The apparatus transmits the first message to the base station to initiate a random access procedure.

Abstract: Methods, systems, and devices are described for transmitting multiple repetitions of a random access shared channel message in multiple slots using beamformed wireless communications. A UE may determine transmission slots for one or more of the multiple repetitions of a random access shared channel message based on slots associated with random access occasions (ROs) that are mapped to an identified synchronization signal block (SSB), such as a SSB associated with a beam that is selected for communications by the UE. In cases where slots with ROs mapped to the identified SSB are not consecutively located, one or more slot offsets may be provided for transmitting the multiple repetitions of the random access shared channel message. Slot offsets may be explicitly indicated by a base station in a random access response message, or may be determined by the UE based on a mapping of SSBs to ROs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may transmit a random access message including a preamble and a payload. A base station may detect the preamble of the random access message. The base station, and may fail or succeed to decode the payload of the random access message. The base station may transmit, based at least in part on detecting the preamble and the different decoding outcome for the payload, a random access response. The random access response may include an uplink group grant and an indication for a type of the uplink group grant for a plurality of UEs whose preamble transmission share the same time and frequency occasion. UEs may monitor the type and the contents of the uplink group grant and transmit data subsequently on a set of shared time frequency resources. Numerous other aspects are provided.
