A method by a user equipment (UE) for transmitting one or more power headroom reports (PHRs) is provided. The method includes receiving, from a base station (BS), a Radio Resource Control (RRC) configuration comprising a first RRC parameter that indicates a first operation mode of multiple PHRs for multiple transmission reception points (TRPs); and transmitting, to the BS, a PHR medium access control control element comprising a first power headroom (PH) associated with a first TRP and a second PH associated with a second TRP. The first TRP and the second TRP are associated with a serving cell of the BS. The first PH is a first Type-1 PH associated with first physical uplink shared channel (PUSCH) transmission toward the first TRP. The second PH is a second Type-1 PH associated with second PUSCH transmission toward the second TRP. The UE is configured with multi-TRP based PUSCH repetitions.

A user equipment (UE) is described. The LE may comprise high-layer processing circuit configured to acquire a first RRC parameter, a second RRC parameter, a third RRC parameter, and a fourth RRC parameter, and transmission circuity configured to transmit a PUSCH in multiple slots.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying one or more first physical uplink control channel (PUCCH) resources in a first component carrier and one or more second PUCCH resources in a second component carrier. The UE may transmit a first one or more PUCCH communications using the one or more first PUCCH resources and a second one or more PUCCH communications using the one or more second PUCCH resources in accordance with the configuration information. Numerous other aspects are described.

A wireless device receives a first downlink control information (DCI) that schedules a reception of a transport block and indicates a hybrid automatic request (HARQ) process number with feedback disabled. The wireless device receives a second DCI that schedules a retransmission of the transport block and indicates the HARQ process number with feedback disabled, where the retransmission of the transport block overlaps in time with at least one symbol of a transmission of an uplink signal. Based on successfully decoding the transport block scheduled by the first DCI, the wireless device drops the retransmission of the transport block scheduled by the second DCI and transmits the uplink signal.

Techniques are disclosed relating to downlink control information for wireless communications. In some embodiments, the downlink control information includes code block group information that indicates which code block groups are transmitted and soft buffer handling information that indicates whether to flush previously-determined soft bits that correspond to one or more code block groups.

This disclosure describes a first slave device that transmits information to a second slave device indicating that a first data packet was improperly received from a master device, so that a corresponding data packet may be relayed from the second slave device to the first slave device. In an aspect, the second slave device may receive a first data packet followed by an indication that the first slave device improperly received the first data packet, where the second slave device is configured to relay the first data packet to the first slave device in response thereto. In another aspect, the second slave device may receive a request to listen for a separate data stream of the first slave device based on a first data packet being improperly received by the first slave device and transmit a second data packet of the separate data stream to the first slave device.

A resource determination method and apparatus, a node and a non-transitory computer-readable storage medium are disclosed. The method may include: acquiring, by a first communication node, configuration information configured by a second communication node; and selecting, by the first communication node, a target resource among a plurality of pre-configured resources according to the configuration information, where the pre-configured resources are time and frequency domain resources configured by the second communication node.

The present disclosure describes method, systems, and devices for transmitting feedback information by a communication node. The method includes sending a hybrid automated repeat request-acknowledgement (HARQ-ACK) in response to a preset rule being satisfied.

A wireless device receives a first downlink control information (DCI) comprising a first hybrid automatic request (HARQ) process identifier and a first new data indicator (NDI). A second DCI is received with the first HARQ process identifier and a second NDI. The second NDI is considered as toggled regardless of a value of the second NDI in response to the first DCI indicating postponing a HARQ acknowledgement transmission for a HARQ process identified by the first HARQ process identifier. The wireless device flushes a HARQ buffer associated with the HARQ process based on the second NDI being toggled.

Apparatus, methods, and computer-readable media for semi-persistent scheduling (SPS) physical uplink control channel (PUCCH) hybrid automatic repeat request (HARQ) deferral for PUCCH groups are disclosed herein. A user equipment (UE) may receive, from a base station, a downlink configuration of a first physical uplink control channel (PUCCH) group that configures a first hybrid automatic repeat request (HARQ) feedback payload corresponding to a first semi-persistent scheduling (SPS) downlink packet for deferral and does not configure a second HARQ feedback payload corresponding to a second SPS downlink packet for deferral. The UE also may delay transmission of at least the first HARQ feedback payload based on different configurations for HARQ feedback deferral between the first SPS downlink packet and the second SPS downlink packet.
