The present disclosure proposes an operation method of a terminal operating on the basis of one primary cell (PCell) and one or more secondary cells (SCell) in a wireless communication system, and a terminal supporting same. According to one embodiment applicable to the present disclosure, a terminal may adaptively change a PRACH resource having successfully performed BFR to an uplink beam of an SCell or maintain an uplink beam of an existing SCell, on the basis of whether an uplink beam related to a PCell is possible to be used as an uplink beam related to the SCell. Through this, the terminal may properly manage the uplink beam of the SCell.

A method including obtaining parameters for a flow from a first network through a second network, the parameters including: a maximum protocol data unit volume PDUV.sub.max in the first network, a maximum flow bit rate MFBR in the second network, a guaranteed flow bit rate GFBR in the second network, and a maximum protocol data unit delay budget in the second network; deriving from the obtained parameters: a maximum delay a packet of the flow experiences in the second network, wherein the maximum delay is a sum of a maximum PDUV.sub.max dependent contribution and a maximum PDUV.sub.max independent contribution, a minimum delay the packet experiences in the second network, wherein the minimum delay is a sum of a minimum PDUV.sub.max dependent contribution and a minimum PDUV.sub.max independent contribution.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for transmitting, from a user equipment (UE) to a base station, a report indicating a beamforming capability of the UE, receiving, from a base station, a configuration for a plurality of control resource sets (CORESETs) based at least in part on the report, selecting multiple CORESETs of the plurality of CORESETs, and monitoring the selected multiple CORESETs during a monitoring occasion. In some examples, the UE may also monitor one or more unselected CORESETs that have a quasi co-location relationship with one of the selected CORESETs.

This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit to a base station (BS), information indicating a medium access control (MAC) security capability of the UE. The UE may receive from the BS, a communication that includes an indication of a MAC security configuration for communications between the UE and the BS. The indication of the MAC security configuration may be based at least in part on the MAC security capability of the UE. Numerous other aspects are provided.

A dictionary configuration method, a buffer control method, a network side device and a UE are provided. The buffer control method for the network side device includes: receiving, by the network side device, first check information transmitted by the UE; determining, by the network side device, whether content in a compression buffer of the UE is identical to content in a decompression buffer of the network side device; and when the content in the compression buffer is different from the content in the decompression buffer, transmitting, by the network side device, buffer resetting information to the UE.

Methods for a network device and a terminal device for Semi-Persistent Scheduling (SPS) are disclosed. A method comprises sending, to a terminal device, a first uplink (UL) SPS configuration message via a Layer 1 signal to configure or deconfigure a UL SPS grant in a cell among one or more cells configured to the terminal device; and receiving, from the terminal device, a first Media Access Control (MAC) Control Element (CE) for confirmation of the first UL SPS configuration message, wherein the first MAC CE comprises a first indicator to confirm the first UL SPS configuration message, or wherein there is a correspondence between the first UL SPS configuration message and the first MAC CE when there are two or more first UL SPS configuration messages to be sent and two or more first MAC CEs to be received.
