In a method for data transmission, a plurality of data packets is received from a user plane function (UPF) entity of a core network. Each of the plurality of data packets is associated with a same service flow identifier. The received plurality of data packets is transmitted to user equipment (UE). When the transmission to the UE of one of the plurality of data packets fails and the one of the plurality of data packets is identified as a first data packet type that affects recovery of at least one other data packet in the plurality of packets, the transmission of the at least one other data packet in the plurality of data packets is stopped.

A wireless device receives one or more radio resource control messages indicating: a first transmission and reception point (TRP) of a cell, a second TRP of the cell, and one or more first beam failure recovery parameters indicating one or more first reference signals for the first TRP of the cell. A first beam failure is determined based on the one or more first reference signals, of the first TRP, indicated by the one or more first beam failure recovery parameters. Based on the determining, an uplink signal indicating a link recovery request for the first TRP is transmitted via the second TRP of the cell.

The present invention relates to a wireless communication system. Specifically, the present invention relates to a method for transmitting, by a terminal, an HARQ-ACK in a CA wireless communication system and a device therefor, the method comprising the steps of: receiving a first PDCCH including a first DAI and a second DAI within SF #n-k; configuring an HARQACK payload using the first DAI and the second DAI; and transmitting the HARQ-ACK payload in SF on, wherein the value of the first DAI indicates the order values of scheduling of cell/SF units associated with the first PDCCH in SF #n-k, the order values of scheduling of cell/SF units are counted in a manner in which priority is given to cells in the cell/SF domain, and the value of the second DAI corresponds to a value obtained by accumulating the numbers of cells scheduled for the terminal by a DG DCI in each SF from the first SF to the SF, in which the first PDCCH is received, within SF #n-k (k #K).

An indirect data transmission method may include: calculating an estimated arrival time of a next poll data request of a terminal device according to a receipt time of a poll data request, after the poll data request is received from the terminal device; transmitting data for the terminal device to a cache of a Media Access Control (MAC) layer module at a time point which is a predetermined time length ahead of the estimated arrival time responsive to a determination that there is the data for the terminal device in a network layer module; and transmitting, to the terminal device, an acknowledgement packet indicating that there is the data to be transmitted in the cache of the MAC layer module and the data for the terminal device, responsive to receiving the next poll data request.
