Abstract: Methods, systems, and devices for wireless communications are described. Random access channel (RACH) occasions may be scheduled on each component carrier (CC) of a carrier aggregation (CA) configuration that includes both a time division duplexing (TDD) TD Raid band and at least one frequency division duplexing (FDD) band based on a synchronization signal/physical broadcast channel block (SSB) received in the TDD band. In some cases, the TDD band may be used to configure the RACH occasions in same and/or different CCs. Additionally or alternatively, the FDD band may configure the RACH occasions on its uplink CC based on SSBs received on other CCs. Additionally, the RACH occasions may be configured such that the UE avoids unavailable uplink slots when transmitting a first RACH message in a RACH occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive system information indicating a first set of resources allocated for transmission of random access messages and a second set of resources for requesting on-demand signaling. The UE may transmit a random access message via the first set of resources, and may transmit a request for on-demand signaling via the second set of resources. Upon receiving the random access message, a network entity may transmit a random access response (RAR) indicating a third set of resources allocated for reception of random access messages. Upon receiving the request, the network entity may transmit an indication of a fourth set of resources allocated for transmission of the on-demand signaling. Accordingly, the UE may retransmit the random access message via the third set of resources, and may receive the on-demand signaling via the fourth set of resources.

Abstract: Wireless communications systems and methods related to resource partitioning for sidelink are provided. A first user equipment (UE) transmits, to a second UE, a time-division duplexing (TDD) configuration indicating a first set of resources time-multiplexed with a second set of resources in a sidelink resource pool, wherein the first set of resources is associated with a first link, and wherein the second set of resources is associated with a second link different from the first link. The first UE receives from the second UE over the first link, a first communication signal in a resource of the first set of resources. The first UE transmits, to the second UE over the second link, a second communication signal using a resource of the second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may configure a user equipment (UE) with a low latency mode indication that indicates one or more different retransmission timelines or repetition techniques relative to communications that are not associated with the low latency mode indication. The base station may provide the low latency mode indication in downlink control information (DCI) that may include a resource grant for uplink resources for an uplink communication, such as for a UE transmission of pose information of an extended reality (XR) application. The low latency mode indication may signal that no retransmissions of the uplink communication are to be transmitted, that a different retransmission timeline is enabled for low latency mode communications, that retransmissions may happen based on a particular timeline that is determined according to one or more timers, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive a configuration for a first random access message of a two-step random access channel procedure. The wireless device may select a subcarrier spacing and a number of demodulation reference signal occurrences for transmitting the first random access message based at least in part on the configuration and a speed of the wireless device. The wireless device may transmit the first random access message of the two-step random access channel procedure using the subcarrier spacing and the number of demodulation reference signal occurrences.

Abstract: Apparatus, methods, and computer-readable media for performing random access procedures based on two-step random access channel procedures and four-step random access channel procedures are disclosed herein. An example method for wireless communication at a User Equipment (UE) includes determining that a fallback timer associated with a two-step random access procedure is configured for the UE. The example method also includes generating a random access message based at least on the determining. The random access message may be one of a first-type random access message associated with a four-step random access procedure and including a preamble or a second-type random access message associated with the two-step random access procedure and including the preamble and a payload. Further, the example method includes performing a random access attempt by transmitting, to a base station, the random access message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, one or more control messages that indicate a configuration for a first downlink bandwidth part (BWP) associated with a first operating mode of the UE, a second downlink BWP associated with a second operating mode of the UE, a first set of resources within the first downlink BWP, and a second set of resources within the second downlink BWP. At least a portion of the configuration may correspond to a capability of the UE. The UE may monitor the first set of resources while in the first operating mode, and may monitor the second set of resources while in the second operating mode. The UE may receive a system information update or a public warning system (PWS) notification from the network entity via the second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive a configuration of a set of search space sets for a downlink control channel. The UE may determine a quantity of downlink control channel units (e.g., downlink control channel elements, downlink control channel candidates) for monitoring over the set of search space sets, where downlink control channel units that overlap may be counted separately. For instance, the downlink control channel units may overlap in time and frequency and/or may have a same associated payload size and associated set of control channel elements. The UE may monitor the downlink control channel according to a subset of the set of search space sets, where the subset excludes one or more of the set of search space sets based on the quantity of downlink control channel units satisfying a threshold.
