The embodiments of the present disclosure provide a method and apparatus for distinguishing between data formats, and a communication device. The method includes a terminal receives a downlink data packet, and determines whether the data format of the downlink data packet is a first data format or a second data format, wherein the first data format indicates that the downlink data packet is encrypted using a first key of a source base station and/or compressed using a first header compression format of the source base station, and the second data format indicates that the downlink data packet is encrypted using a second key of a target base station and/or compressed using a second header compression format of the target base station.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improved handling of adjacent channel interference in multi-link aggregation scenarios. In accordance with the described techniques, a device may establish a set of wireless links for communication with a second device, the set of wireless links supporting parallel transmission during at least a first duration of a multi-link session, the set of wireless links including at least a first wireless link and a second wireless link. The device may modify a transmission parameter for the first wireless link or a clear channel assessment (CCA) parameter for the second wireless link, or a combination thereof. The device may then perform the CCA procedure on the second wireless link and transmit at least a first portion of the message on the first wireless link based on the modified transmission parameter or modified CCA parameter.

A data transmission method and an apparatus. A transmission priority of a data packet may be changed so that the data packet has an opportunity to continue to be transmitted. when the data packet just arrives at a PDCP layer of a communication apparatus, and the priority of the data packet is an initial priority. If the data packet is not sent or is not successfully sent after a decoding moment of a receiver is exceeded, compared with a manner of directly discarding the data packet, in this manner, the priority of the data packet may be changed, so that the data packet has the opportunity to continue to be transmitted. This helps improve a compression rate and a decoding effect, to improve user experience.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for retransmission of sidelink transmissions using network coding. A transmitting device transmits a transport block and a request for a NC encoding device to retransmit the transport block to a plurality of UEs. The NC encoding device transmits a packet encoding a plurality of transport blocks previously transmitted by one or more transmitting devices. The NC encoding device receives a plurality of acknowledgments (ACK) or negative acknowledgments (NACK) for the plurality of transport blocks from the plurality of UEs. The NC encoding device determines whether a respective transport block has satisfied an ACK condition based on the plurality of ACKs or NACKs from the plurality of UEs. The NC encoding device transmits an acknowledgment message to the one or more transmitting devices for at least the respective transport block.
