Abstract: A user equipment (UE) may make a joint decision of adaptive receive diversity (ARD) and adaptive transmit diversity (ATD) configurations, including transmit (Tx) and receive (Rx) antennas selection and/or blanking based on downlink (DL) and uplink (UL) traffic conditions. The UE may disable at least one Tx chain for a transmission of a codebook-based sounding reference signal (SRS) (SRS-CB) based on one or more of at least one DL traffic condition or at least one UL traffic condition, and transmit, to a base station, upon disabling the at least one Tx chain, the SRS-CB via an antenna associated with at least one active Tx chain.

Abstract: The techniques described herein may provide for sub-slot based physical uplink shared channel (PUSCH) repetition (i.e., back-to-back PUSCH repetition within a slot) according to user equipment (UE) capability. A UE may employ uplink data repetition capability reporting for base station scheduling of uplink data repetition and base station management of the number of transport blocks (TBs) that a UE supports (e.g., processes and transmits for uplink) on a per-slot basis. According to the techniques described herein, a UE may indicate whether it supports mini-slot repetition (e.g., for ultra-reliable low-latency communication (URLLC), enhanced mobile broadband (eMBB), or both) via an uplink data repetition capability report. The uplink data repetition capability report may further indicate a maximum number of supported repetitions per TB, a number of supported TBs per slot, etc., such that a base station may configure or schedule PUSCH repetition based on the UE's reported capability.

The UE may further perform the PUSCH transmission including the UCI REs.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) receiving a first transmission scheduling resources for a second transmission having a first priority. The UE may determine that one or more symbols of the second transmission are to be unused due to receipt of a cancellation indication or due to identifying a conflict, for example, with higher priority resources. Based on determining that the symbols are to be unused, the UE may determine that the base station will not reschedule the unused resources for another transmission, for example, having the first priority. The UE and the base station may communicate based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may interrupt a user equipment (UE) during transport block (TB) encoding. The UE may cancel transmission (e.g., suppress processing) of a TB based on the interruption, such that a first subset of code blocks is encoded and a second subset is unencoded. In some cases, the UE may receive a re-transmission request for a code block including cyclic redundancy check (CRC) bits for the TB, where the CRC bits are not prepared. In one example, the UE may modify the CRC bits (e.g., set them to a common value, drop them, etc.) to reduce processing time. In another example, the base station may request re-transmission of all preempted code blocks, supporting TB CRC calculation. In another example, the base station or UE may extend a processing timeline for the re-transmission to support TB CRC calculation.

Abstract: Wireless communication devices, systems, and methods related to communicating UCI are provided. For example, a method of wireless communication may include receiving, by a user equipment (UE) from a base station (BS), scheduling information for transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) and uplink control information (UCI) during a time period. The UCI may include channel state information (CSI) or a scheduling request (SR). The method may include determining, by the UE, that the UCI and a HARQ-ACK codebook have a common priority, the HARQ-ACK being based on the HARQ-ACK codebook. The method may include transmitting, by the UE to the BS, the HARQ-ACK and the UCI during the time period based on the scheduling information, the transmitted UCI using resources determined based on a duration associated with the HARQ-ACK codebook, and the duration being based on the UCI and the HARQ-ACK codebook having the common priority.

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: Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.
