Provided according to an embodiment of the present disclosure is a method for performing sidelink communication by a first device. The method may comprise the steps of: transmitting a PSCCH to a second device on the basis of one sub-channel among M sub-channels associated with a sidelink slot; and transmitting a PSSCH associated with the PSCCH to the second device on the basis of N sub-channels among the M sub-channels.

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for indicating sidelink CSI information to a base station. A UE and a base station may determine a priority of a sidelink CSI report on an uplink channel in association with a priority of one or more of at least one uplink transmission or at least one other sidelink transmission. The sidelink CSI report may correspond to one or more sidelink transmissions between the UE and at least one other UE. The UE may transmit, and the base station may receive, via the uplink channel, the sidelink CSI report based on the priority of the sidelink CSI report on the uplink channel being determined in association with the priority of the one or more of the at least one uplink transmission or the at least one other SL transmission.

A UE may multiplex first UCI of a first priority with second UCI of a second priority. The first UCI may include at least one of a first modulation order or a first number of MIMO layers, and the second UCI may include at least one of a second modulation order or a second number of MIMO layers. The first modulation order of the first UCI may be greater than or equal to the second modulation order of the second UCI, and the first number of MIMO layers of the first UCI may be greater than or equal to the second number of MIMO layers of the second UCI. The UE may transmit, to a base station, an UL transmission including the first UCI of the first priority multiplexed with the second UCI of the second priority, where the second priority corresponds to a higher priority than the first priority.

Methods and apparatus are described for transmitting hybrid automatic repeat request-acknowledgement (HARQ-ACK) bits in a physical uplink shared channel (PUSCH) by a user equipment (UE) in a communication system. A method includes receiving a configuration of a plurality of cells, the plurality of cells being associated with one or more transport blocks; arranging HARQ-ACK bits for the plurality of cells, based on an order of cell indexes and an order of transport block indexes; encoding the arranged HARQ-ACK bits; and transmitting, to a node B, the encoded arranged HARQ-ACK bits in the PUSCH. 2 HARQ-ACK bits for a cell configured with 2 transport blocks are included in the arranged HARQ-ACK bits. The arranged HARQ-ACK bits are encoded by a (32, O) block code in case that a number of the arranged HARQ-ACK bits is 3, O being the number of the arranged HARQ-ACK bits.

This disclosure describes systems, methods, and devices related to transmit power control (TPC). A device may identify a link measurement request frame from a first station device. The device may determine, for each transmit chain of the first station device, a TPC action to be performed by the first device. The device may cause to send a link measurement report frame comprising a value indicative of the TPC action for each transmit chain. The device may identify an acknowledgement from the first station device.

Provided are a control information indicating method, a communication node and a computer-readable storage medium. The method includes: sending, by a first communication node, control information to a second communication node, where the control information is used for indicating the scheduling of one or more transport blocks, each transport block corresponds to a respective one of hybrid automatic repeat request (HARQ) processes when being scheduled, and each HARQ process has a corresponding HARQ process index and new data indication (NDI) information.

A method for transmitting or receiving a frame by a STA in a WLAN according to one embodiment of the present invention may comprise the steps of: receiving a first frame including a PHY header and an A-PHDU obtained by aggregating PHDUs which are PHY data transmission units for a HARQ process; decoding at least one PHDU for the STA in the A-PHDU on the basis of the PHY header; and transmitting a second frame including ACK/NACK information on each of the at least one PHDU for the STA, according to a decoding result, wherein a CRC is individually provided to each of the PHDUs included in the A-PHDU, and the STA transmits a NACK through the second frame in relation to a particular PHDU for which a CRC failure has occurred during the decoding of the particular PHDU.

A user equipment (UE) receives downlink communication that triggers a channel state information (CSI) report. Then the UE determines whether to report CSI together with hybrid automatic repeat request (HARQ) feedback. Then the UE transmits the CSI and the HARQ feedback based on the determining whether to report the CSI together with the HARQ feedback.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling that may identify a configuration for channel state information reporting associated with both a first target block error rate and a second target block error rate. The UE may receive one or more reference signals associated with the channel state information reporting. Further, the UE may transmit, to the base station, the channel state information reporting that may include first channel state information for the first target block error rate and second channel state information for the second target block error rate. In some examples, each of the first channel state information and the second channel state information may be based on the received reference signals.

An Uplink Control Information UCI transmission method, a UCI transmission device, a terminal, and a base station are provided. The method includes: selecting one of a plurality of first UCIs as a target UCI, when there are a plurality of transmissions of first UCIs, a plurality of Physical Uplink Control Channels PUCCHs respectively carrying the first UCI do not overlap in time domain, and all of the plurality of PUCCHs carrying the first UCI overlap with a PUCCH carrying a second UCI in time domain; multiplexing the target UCI and the second UCI.
