Embodiments of the present invention relate to the technical field of wireless communications, and provide a communication method and apparatus, for improving a transmission gain of an uplink signal. The method comprises: a terminal device determines, in an uplink resource, at least one first sub-band for transmitting an uplink signal; the terminal device transmits the uplink signal according to the received indication information, sent by a network device, of the uplink signal and the at least one determined first sub-band, wherein the indication information is used for indicating a transmission parameter and/or a transmission antenna of the uplink signal. According to the method, a terminal can determine, on the uplink resource, the first sub-band for transmitting the uplink signal, and the terminal and the network device transmit, according to the indication information of the uplink signal, the uplink signal on the determined first sub-band, so that the transmission gain of the uplink signal is improved.

The present disclosure relates to a communication technique for merging, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure can 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, and the like) on the basis of a 5G communication technology and an IoT-related technology. The present disclosure discloses a method and apparatus for transmitting and receiving downlink grant-free-based data.

Examples of the present disclosure provide a data processing method and apparatus, a communication device and a storage medium. Being applied to a first Access Point (AP), the data processing method includes: resource allocation information of one or more second Basic Service Sets (BSSs) that use a same frequency band as a first BSS for the first AP is acquired; and a resource is allocated to a station within the first BSS according to the resource allocation information.

A method and apparatus for autonomous changing for dormant bandwidth part in a wireless communication system is provided. A wireless device configures a cell group including a certain cell on which a PUCCH is configured. A wireless device activates a dormant BWP of the certain cell to be an active BWP of the certain cell, wherein no PDCCH is configured on the dormant BWP. A wireless device switches the active BWP of the certain cell from the dormant BWP to another BWP upon triggering the scheduling request procedure, wherein at least one PDCCH is configured on the other BWP.

A method for channel resource transmission and devices are provided. The method includes: determining, by a terminal device, a number of first resource elements (REs) for a first uplink control information (UCI) and a number of second REs for a second UCI respectively, the first UCI being carried on a first physical uplink shared channel (PUSCH), the second UCI being carried on a second physical uplink control channel (PUCCH), wherein the first PUSCH overlaps with the second PUCCH in time domain, and the first UCI has a higher priority than the second UCI; mapping, by the terminal device, the second UCI into REs of the first PUSCH with the number of the second REs, and transmitting, by the terminal device, the first PUSCH carrying the first UCI and the second UCI to an access-network device.

This disclosure provides systems, methods and apparatus for a signaling mechanism associated with activating a secondary cell (SCell) for uplink control information (UCI), including under circumstances in which the SCell is deactivated and belongs to a timing advance group (TAG) lacking a valid timing advance (TA) value. In one aspect, a user equipment (UE) and one or more components of a network entity may employ a signaling mechanism for establishing an SCell as a PUCCH-SCell in scenarios in which the PUCCH-SCell belongs to a secondary TAG (sTAG) lacking a valid TA value. The signaling mechanism may include signaling to directly provide the network entity with beam measurement information associated with one or more SCells of the sTAG or may include singling that the network entity may use to derive the beam measurement information associated with the one or more SCells of the sTAG.

Methods, systems, and devices for sounding reference signal (SRS) resource indicator (SRI) association for configured grant (CG) based transmission and reception point (TRP) physical uplink shared channel (PUSCH) transmission are described. In some examples, a user equipment (UE) may receive first control signaling indicating a first and second sounding reference signal (SRS) resource set associated with a first and second set of power control parameter, respectively. The UE may receive second control signaling indicating a CG configuration, the first and second power control parameters for transmissions in the CG configuration. In some examples, the UE may determine a configuration status for one or more fields the first control signaling, the second control signaling, or both. The UE may select an SRS resource set based on the configuration status and may transmit one or more CG uplink transmissions with the CG configuration using the selected SRS resource set.

A base station may identify a configuration of one or more time gap periods associated with FD beam pair quality measurement. The base station may transmit, to the UE, and the UE may receive, from the base station, an indication of the configuration of the one or more time gap periods associated with FD beam pair quality measurement. The UE may perform, during the one or more time gap periods, one or more measurements of a quality of one or more FD beam pairs. Each of the one or more FD beam pairs may include an uplink beam and a downlink beam. The UE may identify at least one failed FD beam pair in the one or more FD beam pairs based on the one or more measurements of the quality of the one or more FD beam pairs and an SI measurement.

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.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may extract, from a neighboring base station with cell coverage that overlaps cell coverage of the base station, information associated with user equipment (UE) transmission of MsgA messages. The base station may select, based at least in part on the information, a physical uplink shared channel (PUSCH) resource to allocate to a UE for transmission of a MsgA message. The base station may transmit, to the UE, an allocation of the PUSCH resource. Numerous other aspects are described.
