Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improving communications between a user equipment (UE) and a base station in a shared radio frequency spectrum while the UE is operating in a discontinuous reception (DRX) mode. In particular, the UE may be configured to adapt operation in a DRX mode based on whether a base station has access to a shared radio frequency spectrum. For example, the UE may adjust a length of an on-duration for monitoring for a data transmission from the base station, adjust a periodicity for monitoring for control information from the base station, determine whether to keep monitoring for wake-up signaling from the base station, etc. based on whether the base station has access to the shared radio frequency spectrum. Further techniques for improving operation in a DRX mode are also described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an uplink communication, associated with a reference duration, in an uplink burst. The UE may receive hybrid automatic repeat request (HARQ) feedback after transmitting the uplink communication. The UE may adjust a size of a listen before talk (LBT) contention window based at least in part on whether the HARQ feedback is associated with the reference duration. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to configured transmissions in a shared radio frequency band are provided. A user equipment (UE) receives, from a base station (BS), an indication of a first configured resource in a shared radio frequency band for a communication in a first direction. The UE receives, from the BS, a first configuration to select between a validation of the first direction or an absence of an invalidation of the first direction for using the first configured resource for the communication. The UE communicates, with the BS, the communication in the first direction using the first configured resource based on the first configuration.

Abstract: The present disclosure relates to wireless communications, and more particularly to enhancements to a random access channel (RACH) procedure for use in New Radio (e.g., 5G) communications in the unlicensed spectrum (also referred to as NR-U). The present disclosure provides a user equipment (UE) or network entity that determines an available RACH occasion (RO) within a slot for a message transmission according to one of a two-step RACH procedure or a four-step RACH procedure, wherein the available RO is adjacent to at least one unavailable RO within the slot. The UE or network entity may further perform, during the RO, the message transmission according to one of the two-step RACH procedure or the four-step RACH procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a control channel resource configuration associated with an unlicensed spectrum, wherein the control channel resource configuration is associated with an indication of whether a resource to be used for an uplink control channel in the unlicensed spectrum is a fixed resource, a floating resource, or an adaptive resource. The UE may identify the resource based at least in part on the control channel resource configuration. The UE may transmit uplink control information on the identified resource. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication in a shared spectrum. In some aspects, a user equipment may receive an indication of a set of starting offsets for an uplink communication, wherein the set of starting offsets includes at least one negative starting offset relative to a start of a slot or a mini-slot in which the uplink communication is configured to start; select a starting offset from the set of starting offsets; and transmit the uplink communication, wherein the uplink communication starts at a time indicated by the selected starting offset.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. In some aspects, a user equipment (UE) may enable adaptive receive diversity (RxD) by receiving an indicator for a channel occupancy time (COT), outside of the COT and in a non-RxD mode, and may transfer to the RxD mode for reception during the COT. After an end to the COT, the UE may return to the non-RxD mode. In this way, the UE enables improved power gain, diversity gain, or spatial nulling gain during a COT, and enables reduced power utilization outside of the COT.

Abstract: A method of wireless communication of a user equipment (UE) includes communicating with a base station using a baseline channel code. The UE indicates to the base station, using the baseline channel code, support for an additional channel code that is different than the baseline channel code. The UE receives, from the base station, an indication to operate using the additional channel code. Then, the UE receives a first transmission on first set of resources and a second transmission on a second set of resources from the base station, the first transmission being encoded with the baseline channel code and the second transmission being encoded with the additional channel code.
