Provided are methods and devices for sending and receiving a channel state information (CSI) report, and electronic devices. The method for sending a CSI report includes that a terminal determines priorities of M CSI reports, where M is a natural number not less than 1; an available channel resource is selected from a channel resource set for receiving the M CSI reports, where the channel resource set includes J channel resources supporting reception of the M CSI reports and J is a natural number not less than 1; and at least one CSI report is transmitted according to the priorities by using the available channel resource.

A method for HARQ feedback indication includes: determining to send current downlink data to a terminal; generating uplink HARQ feedback indication information for the current downlink data, wherein a timing relationship indicated by the uplink HARQ feedback indication information is obtained from a first set of timing relationships between a time domain unit of downlink data for the terminal and a time domain unit of an uplink HARQ feedback of the downlink data; and sending to the terminal the current downlink data and downlink control information (DCI) carrying the uplink HARQ feedback indication information. A dynamic HARQ feedback can be realized by a terminal.

The present disclosure relates to a method, user equipment, a node and a computer readable medium for controlling data duplication transmission function. The method can include: receiving first control information sent from a master node, and/or receiving second control information sent from a secondary node; and determining, based on an indication of a first quantity of data radio bearers (DRB) corresponding to the first control information, and/or based on an indication of a second quantity of DRBs corresponding to the second control information, to open or close a data duplication transmission function of at least one DRB.

A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voiceover-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.

This application provides a data transmission method and apparatus. The method includes: obtaining significant bits in an N.sup.th data frame, where N is an integer greater than or equal to 1, a quantity of the significant bits in the N.sup.th data frame is smaller than a quantity of bits in the N.sup.th data frame, and remaining bits other than the significant bits in the N.sup.th data frame are insignificant bits in the N.sup.th data frame; and sending the significant bits in the N.sup.th data frame, and skipping sending the insignificant bits in the N.sup.th data frame. According to the application, on a premise of ensuring voice intelligibility, a transmit end apparatus transmits only the significant bits, to minimize a data transmission amount, thereby improving transmission reliability and coverage.

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.
