An uplink transmission and reception method and device in wireless communication system are disclosed. A method by which a terminal performs uplink transmission in a wireless communication system, according to one embodiment of the present disclosure, may comprise the steps of: receiving configuration information related to a plurality of sounding reference signal (SRS) resource sets; receiving downlink control information (DCI), which indicates at least one from among a first SRS resource set, a second SRS resource set, or the first SRS resource set and the second SRS resource set and includes information indicating at least one SRS resource in the indicated at least one SRS resource set; and performing the uplink transmission on the basis of the indicated at least one SRS resource.

Methods, systems, and devices for wireless communication at a first user equipment (UE) are described. A UE may receive a control signal indicating a set of durations. A duration of the set of durations may be scheduled for uplink resources and additional resources including downlink resources, flexible resources, or both. The UE may further receive an indication of a slot format configuration permitting sidelink communications on the uplink resources during the duration scheduled for the uplink resources and the additional resources. Upon identifying that sidelink communications are permitted, the UE may transmit a sidelink transmission using the uplink resources and during the duration.

Certain aspects of the present disclosure provide techniques for wireless communication. The techniques include a method wireless communication by a user equipment including receiving a first physical downlink control channel (PDCCH) from a first transmission reception point (TRP) and a second PDCCH from a second TRP, wherein the first PDCCH and the second PDCCH include the same downlink control information (DCI), selecting a physical uplink control channel (PUCCH) resource for transmitting hybrid automatic repeated request acknowledgment (HARQ-ACK) feedback based on one of the first PDCCH or the second PDCCH, and transmitting a PUCCH that includes the HARQ-ACK feedback using the selected PUCCH resource.

In accordance with example embodiments of the invention there is at least a method and apparatus to perform receiving, by a network device, information comprising a multiple transmission time interval uplink grant with cyclic redundancy check bits scrambled by a radio network temporary identifier; determining, by the network device of a communication network, a subset of data transmissions of a previous burst of data transmissions to be retransmitted by the network device; and performing by the network device retransmission of the subset of data transmissions using scheduled resources of the uplink grant. In addition, to perform determining, by a network node of a communication network, information comprising a multiple transmission time interval uplink grant with cyclic redundancy check bits scrambled by a radio network temporary identifier to identify a subset of data transmissions of a previous burst of data transmissions to be retransmitted by a network device; and sending the information towards the network device for use in retransmission of the subset of data transmissions using scheduled resources of the uplink grant.

A communication device is configured to communicate with a second communication device, the communication device comprising circuitry configured to transmit one or more data frames to the second communication device that require a response by he second communication device, listen to a first response acknowledging receipt of at least one of the one or more data frames from he second communication device, and, if a first response is not received, change transmit opportunity configuration and/or channel access for non-data frames and/or data frames.

A wireless device receives configuration parameters indicating: a control resource set (coreset) configured with a first transmission configuration indicator (TCI) state and a second TCI state; and a bitmap comprising a plurality of bits. Each bit of the plurality of bits indicates one of the first TCI state or the second TCI state and is for a respective repetition of repetitions of a downlink control information (DCI). The wireless device receive, via a search space associated with the coreset, each of a plurality of repetitions of a first DCI using an associated TCI state indicated by a respective bit of the plurality of bits.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information that indicates a resource allocation for a downlink transmission and an uplink resource for transmission of a hybrid automatic repeat request (HARQ) codebook. The UE may transmit, to the base station, uplink control information (UCI) that includes an indication of whether transmission of the HARQ codebook is cancelled. Numerous other aspects are described.

Apparatuses, methods, and systems are disclosed for supporting a mixture of BR and HFBT. One apparatus (600) includes a processor (605) that provides a physical (“PHY”) layer (255) and a Medium Access Control (“MAC”) layer (260) and a transceiver (625) that communicates on a sidelink channel. The processor (605) determines (805) a minimum time duration between a first resource for HARQ transmission of the transport block (“TB”) and a second resource for HARQ transmission of the TB. Here, the minimum time duration comprises a sum of: a first time to receive HARQ feedback, a second time to determine whether to perform retransmissions of the TB, and a third time to retransmit the TB. The processor (605) selects (810) a retransmission mode based on the minimum time duration and selects (815) sidelink resources for retransmission of the TB based on the selected retransmission mode.

Methods and systems for operation in a wireless communication system are provided. A first transmission may be initiated using at least a first portion of physical layer resources. A second transmission may be initiated using at least a second portion of the same physical layer resources. The first transmission may be any one of a puncturing transmission, interfering transmission, delay-sensitive transmission, or short transmission. The second transmission may be an on-going transmission or a long transmission.

Techniques are described for multiplexing non-acknowledgement (NACK) only physical uplink control channel (PUCCH) transmission that overlaps in time domain with another uplink control channel transmission. An example wireless communication method includes performing a first determination, by a communication node, whether a scheduling request (SR) transmission needs to be performed in a control channel; performing a second determination, by the communication node and in response to determining that the SR needs to be transmitted in the control channel, that a first resource for a non-acknowledgement (NACK) only transmission in the control channel overlaps in time domain with a second resource for the SR transmission; and transmitting, in response to the second determination, a sequence in the second resource in the control channel, where the sequence indicates the SR and a feedback message for the NACK only transmission.
