A method by which a terminal transmits data in an unlicensed band, and an apparatus using the method are provided. The method comprises: transmitting data to a base station through a physical uplink shared channel (PUSCH) in the unlicensed band; and receiving, from the base station, acknowledgement/negative acknowledgement (ACK/NACK) information about the data in the unlicensed band, wherein the terminal receives, from the base station, timeline information notifying of a time relationship between the PUSCH transmission time point and the ACK/NACK information reception time point.

An operating method of a terminal configured to perform vehicle-to-everything (V2X) communication in a wireless communication system, including signaling a maximum physical sidelink feedback channel (PSFCH) receiving capability to a base station; and receiving a wireless signal transmitted from the base station based on the maximum PSFCH receiving capability, wherein the maximum PSFCH receiving capability is a maximum number of PSFCHs receivable during one time transmission interval (TTI).

A communications method for determining a transmission scheme according to at least one temporal parameter includes providing a communication device, a first transceiver, and a second transceiver, acquiring the at least one temporal parameter, establishing a first link between the communication device and the first transceiver during a first time slot according to the at least one temporal parameter, and establishing a second link between the communication device and the second transceiver during a second time slot according to the at least one temporal parameter. The first time slot and the second time slot are non-overlapped.

A terminal according to one aspect of the present disclosure includes a receiving section that receives first information related to a slot format and second information related to a symbol pattern invalid in transmission of an uplink shared channel, and a control section that controls the transmission of the uplink shared channel to be performed in a time section designated as UL by at least the first information and not designated as invalid by the second information.

A station apparatus according to the present invention includes a physical layer frame generator configured to selectively use a first coding scheme and a second coding scheme, a transmitter configured to transmit a frame including a control signal, and a higher layer processor configured to configure either the first coding scheme or the second coding scheme for information bits included in the frame, based on the control information, wherein the control signal includes first information indicating whether a reception method for changing a carrier sense level is allowed for a communication apparatus that receives the frame.

Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive first downlink control information (DCI) indicating a first redundancy version (RV) index value associated with a hybrid automatic repeat request (HARD) process. The mobile station may transmit, based at least in part on receiving the DCI indicating the first RV index value, data using a second RV index value, the second RV index value being different from the first RV index value. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first set of resources associated with a semi-persistent scheduling (SPS) acknowledgement/negative acknowledgement (A/N) feedback message, wherein the SPS A/N feedback message is deferred to a second set of resources by the UE. The UE may receive an indication of a third set of resources associated with a dynamic A/N feedback message, wherein the second set of resources and the third set of resources are associated with a collision. The UE may perform an action based on the second set of resources and the third set of resources being associated with the collision. The UE may transmit at least one of the SPS A/N feedback message or the dynamic A/N feedback message based on performing the action. Numerous other aspects are described.

Aspects are provided allowing a base station to configure a UE to accumulate CSI over time for downlink data transmissions, and to transfer the accumulated CSI to a base station in a CSI report in response to a CSI report trigger event, thereby improving efficiency in CSI reporting and subsequent transmission reliability. Initially, the base station configures a CSI report trigger event and sends a plurality of data transmissions to a UE. The UE receives the data transmissions and then identifies the CSI report trigger event. Afterwards, the UE sends a CSI report to the base station including a CSI for each of the data transmissions in response to the CSI report trigger event. The base station may then adjust MCS or other parameters for subsequent data transmissions in response to the CSI report.

A method by a UE for performing a random access procedure is provided. The method comprises transmitting a MSGA, monitoring a MSGB-RNTI within a MSGB window starting from an earliest symbol of an earliest PDCCH occasion after the MSGA transmission, receiving the MSGB in a first slot, the MSGB including a success RAR that contains a HARQ Feedback Timing Indicator, a Physical Uplink Control Channel (PUCCH) Resource Indicator, and a UE Contention Resolution Identity, determining, by a MAC entity, to instruct a lower layer to transmit a HARQ feedback in a second slot in response to the reception of the success RAR, delivering, by the MAC entity, the HARQ Feedback Timing Indicator and the PUCCH Resource Indicator to the lower layer, and performing, by the lower layer, a HARQ feedback delivery on an uplink (UL) resource.
