The method also includes receiving a cell activation indication to activate the first serving cell and the second serving cell, activating the first serving cell and the second serving cell, applying the dormant behavior to the first serving cell based on the first indicator when the first serving cell is activated, and not applying the dormant behavior to the second serving cell based on the second indicator when the second serving cell is activated.

A communication method of performing Bandwidth Part (BWP) switching between a non-dormant BWP and a dormant BWP is provided. The communication method is performed by a UE configured by a Base Station (BS) with a serving cell and a dormancy group to which the serving cell belongs. The communication method includes activating the non-dormant BWP as an activated BWP for the serving cell; initializing a first Random Access (RA) procedure on the serving cell; receiving, from the BS, one of a first indication for BWP switching for the serving cell and a second indication for BWP switching for the dormancy group while the first RA procedure is ongoing; switching the activated BWP for the serving cell, based on one of the first indication and the second indication, from the non-dormant BWP to the dormant BWP; and stopping the first RA procedure after receiving one of the first indication and the second indication.

The present specification relates to a method for receiving dormant bandwidth part (BWP) configuration information, performed by a terminal in a wireless communication system, the method comprising: receiving the dormant BWP configuration information from a base station, wherein the dormant BWP configuration information is information about a downlink BWP used as the dormant BWP among at least one downlink BWP set to the terminal; receiving, from the base station, downlink control information (DCI) notifying activation of the dormant BWP; and stopping monitoring of a physical downlink control channel (PDCCH) on the dormant BWP, wherein a BWP inactivity timer is not used on the basis of the activation of the dormant BWP, and the BWP inactivity timer is a timer for a transition to a default BWP.

Various solutions for physical downlink control channel (PDCCH) monitoring enhancement for carrier aggregation (CA) with respect to user equipment and network apparatus in mobile communications are described. An apparatus may transmit a capability report to indicate a supported PDCCH monitoring capability to a network node. The apparatus may receive a PDCCH monitoring configuration compliant with the supported PDCCH monitoring capability from the network node. The apparatus may determine a monitoring budget based on the PDCCH monitoring configuration and the supported PDCCH monitoring capability. The apparatus may perform a PDCCH monitoring according to the monitoring budget.

A first base station (BS) transmitting a secondary node (SN) Addition Request message to a second BS for a communication device; receiving a SN Addition Request Acknowledge message from the second BS, wherein the SN Addition Request Acknowledge message comprises a first plurality of configurations which configure the communication device to communicate with the second BS and configure a data radio bearer (DRB) which is a SCG split bearer; transmitting a first message comprising the first plurality of configurations to the communication device, wherein the second BS communicates with the communication device according to the first plurality of configurations; receiving a second message indicating the SCG failure from the communication device; initiating a SN Modification procedure with the second BS to recover the SCG failure, or transmitting a third message configuring the DRB to be a master cell group bearer or a MCG split bearer to the communication device.

Proposed are a method and device for transmitting an EHT PPDU in a wireless LAN system. Specifically, a transmission device generates an EHT PPDU and transmits the EHT PPDU to a receiving device through a 320 MHz RF band. A legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is determined on the basis of a first technique and a second technique. The first technique acquires an optimal PAPR in the L-STF and the L-LTF. The second technique acquires an optimal PAPR on the basis of the maximum transmission bandwidth supported by the RF. The first phase rotation value is acquired on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is obtained by repeating a phase rotation value defined for an 80 MHz band in an 802.11ax system. The third phase rotation value is defined in 80 MHz band units in a 320 MHz band.

Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

Disclosed are a method for configuring a scheduling request, a network device, a terminal device, and a computer storage medium. The method comprises: receiving at least one bandwidth part (BWP) configured by a network side; and receiving configuration parameters of at least one scheduling request configured by the network side for each BWP, wherein the configuration parameters of the scheduling request have a mapping relationship with a logical channel.

Wireless communications are described. A wireless device may determine a first transmission power for a first signal and a second transmission power for a second signal. The wireless device may reduce signal transmission power of one or more of the first signal or the second signal, based on a calculated power value exceeding an allowable transmission power. The wireless device may reduce the signal transmission power during an overlap period or a non-overlap period, based on a duration of an overlap of the first signal with the second signal.

A method for enhancing Bandwidth Part (BWP) operation towards Secondary Cell (SCell) dormancy indication is proposed. A User Equipment (UE) detects a Downlink Control Information (DCI) format including an SCell dormancy indication that indicates an active BWP change for a serving cell. The UE performs BWP switching for the serving cell in response to the DCI format. The UE stops transmission or reception in the serving cell during a time duration from a slot containing a last symbol of the DCI format, wherein the time duration includes a first period of time of delay for the BWP switching and a second period of time of interruption to other active serving cells.
