Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may be configured to receive a downlink control message (e.g., an uplink grant) that schedules resources for transmitting repetitions of an uplink channel transmission, where each of the repetitions of the uplink channel transmission may correspond to a single transport block. The UE may determine a plurality of sounding reference signal (SRS) resources based on the downlink control message, and transmit different instances of the uplink channel transmission repetitions according to different SRS resources. The described examples for uplink repetitions may support various techniques for uplink coverage enhancement and diversity gains.

A method performed by a terminal in a communication system is provided. The method includes identifying a first physical downlink shared channel (PDSCH) scheduled by a physical downlink control channel (PDCCH), and a second PDSCH without a corresponding PDCCH; identifying that the first PDSCH and the second PDSCH are overlapped in time; and decoding the first PDSCH on a basis that the PDCCH scheduling the first PDSCH ends at least 14 symbols before the starting symbol of the second PDSCH.

The invention refers to a method, performed by a user equipment, UE, for transmitting data based on a plurality of configured grants, CGs, of resources of a wireless network, the method comprising: receiving, from a network node serving the UE, configurations of a plurality of CGs of resources allocated for the UE to transmit data; transmitting, to the network node, an initial transmission of a transport block, TB, of data using first resources associated with a first one of the CGs, wherein the first CG supports a plurality of repetitions of a single TB; selecting second resources associated with a second one of the CGs for transmission of a subsequent repetition of the TB; and transmitting, to the network node, the subsequent TB repetition using the second resources associated with the second CG; the invention further refers to a method in a corresponding network node and to a corresponding UE and a network node respectively.

A wireless device operating in a communication network can, responsive to receiving a downlink control indication (“DCI”) command to activate or reactivate a configured grant (“CG”) configuration, control at least one timer associated with a non-idle hybrid automatic repeat request (“HARQ”) process on the CG configuration. The non-idle HARQ process can include a process of retransmitting a transmission block (“TB”) using the CG for which an associated media access control (“MAC”) protocol data unit (“PDU”) has been submitted to lower layers for transmission to a network node, but for which successful reception acknowledgment has not been received from the network node.

Techniques and apparatuses are described for user equipment-coordination set, UECS, hybrid automatic repeat request, HARQ, that establish a HARQ timeline that is specific to the capabilities of a respective UECS. Compared to a single user equipment, UE, the HARQ timeline for a UECS depends on a number of factors, such as the joint processing capability in the UECS, latency of communication over a local wireless network between the UEs in the UECS, or the like. Based on its capabilities, the UECS can request uplink and/or downlink processing delay times or a UECS-specific HARQ timeline from a base station. The base station grants the uplink and/or downlink processing delay times or the UECS-specific HARQ timeline to the UECS in a layer-1, layer-2, or a layer-3 control message. The use of a UECS-specific HARQ timeline increases the reliability of HARQ signaling for uplink and downlink communication between the UECS and a base station.

A terminal apparatus transmits a PUCCH in a certain slot, and receives multiple DCI formats on a set of PDCCH monitoring occasions corresponding to the certain slot. In a case that multiple PUCCHs exist in the certain slot and that the multiple PUCCHs include a first PUCCH including a first type HARQ-ACK codebook and a second PUCCH including a second type HARQ-ACK codebook, the second PUCCH is not transmitted.

This application discloses a downlink data sending method, a downlink data receiving method, and an apparatus, and relates to the communication field, to resolve a problem that feedback information fails to be sent, and consequently, a retransmission probability of downlink data is increased, and data transmission efficiency is reduced. When at least two of P PDSCHs in one slot overlap in time domain, a network device cancels sending of partially overlapping PDSCHs. If one first PDSCH whose sending is canceled is the last repetition in PDSCH repetitions of first data, and a terminal device receives another repetition in the PDSCH repetitions of the first data before the first PDSCH, the terminal device still sends feedback information for the first data to the network device in a feedback slot corresponding to the first PDSCH.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a semi-persistent scheduling (SPS) downlink communication. The UE may detect a collision between a configured uplink resource associated with a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the SPS downlink communication and a candidate synchronization signal block (SSB) position. The UE may transmit the HARQ-ACK for the SPS downlink communication in the configured uplink resource or in a deferred uplink resource in connection with detecting the collision. Numerous other aspects are described.

This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for semi-persistent scheduling (SPS) and hybrid automatic repeat request (HARQ) feedback skipping for user equipment (UE)-initiated transmissions. A UE configured for extended reality (XR) operations and an SPS configuration including a plurality of SPS occasions, each SPS occasion configured with at least one downlink resource and at least one uplink resource, collects pose information related to at least one SPS occasion. The UE determines, based on the pose information, to skip at least one SPS occasion. The UE sends an indication of the determination to skip the at least one SPS occasion to a base station. The indication is transmitted in a preconfigured uplink resource or may be piggyback an uplink transmission. The base station may reallocate the resources configured for the at least one SPS occasion based on receiving the indication.

A communication device for handling a hybrid automatic repeat request (HARQ) transmission, comprises at least one storage device; and at least one processing circuit, coupled to the at least one storage device, wherein the at least one storage device stores instructions, and the at least one processing circuit is configured to execute the instructions of: receiving a configuration from a network, wherein the configuration comprises a time domain resource allocation (TDRA) table and a set of a plurality of timing values; and receiving a downlink (DL) control information (DCI) from the network, wherein the DCI indicates a row of the TDRA table for at least one physical DL shared channel (PDSCH) reception and indicates a timing value of the set of the plurality of timing values for the HARQ transmission corresponding to the at least one PDSCH reception.
