Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a first set of downlink control information (DCI) formats is associated with a same DCI size as a second set of DCI formats, and perform a padding operation so that the first set of DCI formats and the second set of DCI formats are associated with different DCI sizes. Numerous other aspects are provided.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may select, from a first path and a second path, a path for an uplink communication associated with at least one of a variable payload size for hybrid automatic repeat request (HARQ) feedback or channel state information (CSI) feedback, wherein the first path is on an uplink of the UE and the second path is on a sidelink of the UE; and transmit the uplink communication on the selected path. Numerous other aspects are provided.

Provided is a radio communication device which can make Acknowledgement (ACK) reception quality and Negative Acknowledgement (NACK) reception quality to be equal to each other. The device includes: a scrambling unit (214) which multiplies a response signal after modulated, by a scrambling code “1” or “e.sup.−j(π/2)”, so as to rotate a constellation for each of response signals on a cyclic shift axis; a spread unit (215) which performs a primary spread of the response signal by using a Zero Auto Correlation (ZAC) sequence set by a control unit (209); and a spread unit (218) which performs a secondary spread of the response signal after subjected to the primary spread, by using a block-wise spread code sequence set by the control unit (209).

Provided are a communication device and an SRS transmission method capable of reducing the possibility of a difference in recognition between the presence or absence of an SRS transmission between a base station and a terminal or of an SRS resource so as to prevent degradation of system throughput. At a terminal (200), a reception processing unit (203) detects control information indicating whether or not to request transmission of a sounding reference signal (SRS), whereupon a transmission signal forming unit (207) transmits an A-SRS by way of control by a transmission control unit (206) on the basis of control information. The transmission control unit (206) determines whether or not to execute SRS transmission on the basis of an “SRS Transmission Execution Rule” and the reception status of trigger information.

A method for a serving cell for signaling a communicating with a user equipment (UE) is described. The method may include transmitting, by the serving cell, a radio resource control (RRC) message to the UE. The RRC message may include a plurality of sets of parameters and a plurality of indices corresponding to the plurality of sets of parameters. The method may also include transmitting, by the serving cell, downlink control information (DCI) to the UE indicating an allocated resource block (RB) in a physical downlink shared channel (PDSCH) for the UE and an index corresponding to one of the plurality of sets of parameters to decode the allocated RB.

A wireless device generates a first transport block (TB) in response to receiving a first downlink control information (DCI). The first DCI indicates: a hybrid retransmission request (HARQ) identifier; and a new data identifier (NDI). In response to not detecting a second DCI during a validation duration: the first DCI is invalidated; and transmission of the first TB is dropped. In response to receiving a third DCI indicating a same value of the HARQ identifier, uplink signals are transmitted. The uplink signals comprise, based on the NDI, one of: an adaptive-retransmission of the first TB; or a new transmission of a second TB.

The present disclosure relates to: a communication method for fusing IoT technology with 5G communication systems for supporting higher data transmission rates than preceding 4G systems; and to a system for same. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) based on 5G communication technology and IoT-related technology. The present invention discloses a method for providing a vehicle communication service (vehicle-to-everything, V2X) in a 5G mobile communication system.

A method of transmitting a Random Access Channel (RACH) Occasion configuration to a terminal device and receiving a RACH preamble according to the RACH Occasion configuration. The RACH Occasion configuration comprises a first time resource indication identifying a first set of time resources in which the terminal device is allowed to transmit a RACH preamble according to a first random access procedure, a first frequency resource indication identifying at least a first set of frequency resources in which the terminal device is allowed to transmit the RACH preamble, a second time resource indication identifying a second set of time resources in which the terminal device is allowed to transmit a RACH preamble according to a second random access procedure, and a second frequency resource indication identifying at least a second set of frequency resources in which the terminal device is allowed to transmit the RACH preamble.

A method for UE capability signaling to support enhancements on resource allocation for Physical Downlink Control Channel (PDCCH) candidate monitoring in NR-U is proposed. A UE transfers UE capability information to a mobile communication network. The UE capability information includes information indicating whether the UE supports Control Resource Set (CORESET) configuration with a Resource Block (RB) offset. The UE receives resource allocation configuration of an unlicensed cell from the mobile communication network. The UE monitors PDCCH candidates on the unlicensed cell according to the resource allocation configuration.

Example aspects include a method, apparatus, and computer-readable medium for wireless communication at a user equipment (UE) of a wireless communication network, comprising receiving, from a base station, configuration information scheduling one or more receive occasions and one or more transmit occasions. A full-duplex portion of an overlapping occasion comprises a portion of a first receive occasion of the one or more receive occasions overlapping with a portion of a first transmit occasion of the one or more transmit occasions. A half-duplex portion of the overlapping occasion comprises a remaining portion of the first receive occasion or a remaining portion of the first transmit occasion. The aspects further include performing full-duplex communications during the full-duplex portion of the overlapping occasion using overlapping full-duplex associated parameters. Additionally, the aspects further include performing half-duplex communications during the half-duplex portion of the overlapping occasion using non-overlapping half-duplex associated parameters.
