A method, an apparatus, and a computer program product for wireless communication are provided. A base station (BS) may configure a component carrier group for a user equipment (UE). The BS may provide an indication of a spatial relation for one or more sounding reference signals associated with a component carrier of the component carrier group. The UE may receive the indication and may apply the spatial relation to the one or more sounding reference signals across bandwidth parts of component carriers of the component carrier group.

A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.

The present invention relates to a method for receiving control information by a UE in a wireless communication system, and an apparatus for same. More specifically, the method includes a step of receiving reconfiguration downlink control information (DCI), wherein the reconfiguration DCI includes a plurality of reconfigurations relating to a UE group including the UE and is configured so as to be received on the basis of a radio network temporary identifier (RNTI) defined for the reconfiguration DCI.

Disclosed are a method for performing beam-related reporting in a wireless communication system and an apparatus therefor. Specifically, the method for user equipment (UE) for performing beam-related reporting in a wireless communication system comprises the steps of receiving configuration data from a base station (BS), the configuration data comprising data concerning the reporting period or reporting time of measurement data; receiving a reference signal (RS) from the BS on the basis of the configuration data; measuring on the basis of the RS; transmitting beam change request-related data to the BS on the basis of the measured and threshold values; and transmitting the measurement data to the BS, wherein the beam change request-related data can be transmitted before the reporting period or reporting time.

The present disclosure provides signaling for multi-panel user equipment (MPUE) activation and deactivation status. The MPUE may include a plurality of panels. The MPUE may determine a nominal number of active panels. The MPUE may map a number of panel identifiers equal to the nominal number of active panels to an actual number of active panels of the plurality of panels. The MPUE may receive, from a base station, a downlink control information (DCI) scheduling a communication based on one of the panel identifiers. The MPUE may determine a panel for the communication based on the mapping. The MPUE may communicate according to the DCI using the determined panel.

Network equipment receives, from a User Equipment (UE), an indication that the network equipment is to transition to sparse reference signaling for the UE, and the network equipment then transmits the sparse reference signaling to the UE. The sparse reference signaling is consistent with a sparse signaling pattern, which is determined at the UE based on previous reference signaling previously transmitted to the UE or another UE. At a UE, the sparse reference signaling is received from network equipment, and channel measurement and prediction are performed based on the received sparse reference signaling.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, radio resource control signaling configuring an uplink transmission configuration indication (TCI) state pool that includes multiple candidate uplink TCI states associated with an uplink resource. The base station may transmit, and the UE may receive, downlink signaling that identifies, among the multiple candidate uplink TCI states included in the uplink TCI state pool, an uplink TCI state to be used to transmit an uplink communication on the uplink resource. Accordingly, the UE may transmit, to the base station, the uplink communication on the uplink resource using an uplink transmit beam based at least in part on the uplink TCI state identified in the downlink signaling. Numerous other aspects are provided.

A detection method and an apparatus, applied to the field of communication technologies. The method includes: a terminal-side device performs detection on a plurality of monitoring occasions before a start time of DRX on duration; if the terminal-side device detects first indication information from a network-side device, determining a first time period based on an N.sup.th monitoring occasion in the plurality of monitoring occasions before the start time of the DRX on duration, and performing BWP switching in the first time period. The first indication information indicates the terminal-side device to perform BWP switching. N is an integer greater than 0.

Embodiments of the present disclosure relate to methods, devices and computer readable media for communication of a RS. A method of communication comprises receiving, at a terminal device and from a network device, first information triggering a first communication of a reference signal in a first uplink resource, the first communication being triggered later than a second communication of the reference signal in a second uplink resource; determining, based on a modification result, power adjustment information for the first communication, the modification result indicating whether the second uplink resource is modified; and performing the first communication based on the power adjustment information. Embodiments of the present disclosure can ensure a correct power control for RS communication, and can achieve a dynamic adjustment for a RS communication while considering both flexibility of RS triggering and its related overhead.

A wireless communication system includes one or more communications apparatuses, and a relay device, which is mobile, wherein the relay device includes a transmission unit adapted to transmit a channel change signal to the one or more communications apparatuses, the channel change signal containing channel information that indicates results corresponding to interference levels of a plurality of channels in a frequency band available for use in uplink transmission from the one or more communications apparatuses to the relay device and specifying information used to specify a communications apparatus subject to channel change, and the one or more communications apparatuses include a channel set unit adapted to set a channel having an interference level lower than a threshold as a channel to be used for communications with the relay device when the specifying information contained in the channel change signal is applicable.
