Abstract: The present disclosure discloses apparatuses, systems, and methods of wireless communication that use an adaptive hybrid automatic repeat request (HARQ) procedure and a multi-threaded HARQ procedure for improving HARQ buffer utilization and management. A user equipment (UE) can transmit a reset NACK to reduce the amount of HARQ buffers needed for concurrent HARQ processes. A base station can transmit different redundancy data in a HARQ retransmission depending on the types of NACK the UE transmitted. The base station can communicate with the UE using multiple light HARQ processes or threads that use less HARQ buffers than a typical HARQ procedure. Other aspects, features, and embodiments are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on a determination that a scheduling offset is less than a beam switching latency threshold, a set of beams for communicating with a set of transmit-receive points (TRPs), that use single downlink control information for scheduling, based at least in part on at least one of a transmission configuration indicator codepoint mapping or a control resource set configuration. The UE may communicate with the set of TRPs using the set of beams based at least in part on determining the set of beams. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for performing radio link monitoring (RLM) and radio link failure procedures in multiple-TRP (mTRP) communications, wherein the first TRP is part of a first cell group comprising the first TRP and one or more additional TRPs. The techniques include a method of wireless communication by a user equipment (UE), comprising establishing a plurality of radio links between the UE and a first transmission reception point (TRP) and a second TRP, determining an RLM resource of a first radio link of the plurality of radio links, monitoring the first radio link according to the determined RLM resource, detecting an RLF of the first radio link, determining that the first TRP is associated with the RLF of the first radio link based on the RLM resource of the first radio link, and transmitting an RLF notification indicating the RLF of the first radio link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure, before transmitting a physical downlink shared channel communication, a first resource and a second resource. The BS may transmit the physical downlink shared channel communication using the first resource. The BS may selectively use, after transmitting the physical downlink shared channel communication, the second resource for the reference signal transmission for subband selection and beam selection based at least in part on whether a retransmission event is detected. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method determines resources to monitor for beam failure detection (BFD) when the UE is in a mode of operation involving at least first and second transmitter receiver points (TRPs). The method then detects a beam failure based on monitoring of the determined resources. The method further triggers a beam failure recovery (BFR) procedure based on the detection.

Abstract: Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.

Abstract: This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.

Abstract: For unlicensed high-frequency bands such as mmW bands as used in 5G NR communications, either by regulation or for coexistence with licensed frequency bands, there may be a need for a contention-based access procedure such as the LBT procedure. A challenge is to find a suitable sensing beam to functions as a proxy for a set of transmission beams. In an aspect of the disclosure, a method and an apparatus are provided. The apparatus is configured to determine a set of transmission beams for a transmission opportunity, determine a sensing beam for the set of transmission beams based on a set of beam sensing criteria; and initiate an LBT procedure by sensing an energy on the determined sensing beam. The apparatus may then use the LBT procedure to obtain the access to and transmit data on the determined set of transmission beams.

Abstract: A user equipment (UE) identifies a conflict between a system resource and a wake-up signal (WUS) resource associated with the UE while the UE is operating based on discontinuous reception (DRX). The UE modifies DRX operation in response to identifying the conflict between the system resource and the WUS resource. A base station identifies a conflict between a system resource and a WUS resource for a UE operating based on DRX. The base station modifies a transmission to the UE in response to identifying the conflict between the system resource and the WUS resource.
