A wireless local area network (WLAN) communication method and apparatus using multiple transmission speed partitioning and cooperative transmission are disclosed. The WLAN communication method includes transmitting, by access point to the nodes, transmission time slots, partitions and internal transmission priorities using transmission time slot information, partition information and internal transmission priority information, receiving uplink packet from one node, determining whether downlink data to be transmitted to the high speed or the low speed node is present, or not in the download queue, transmitting, if present, the downlink packet to the nodes, removing downlink data from the download queue for ACK, and transmitting, if not present, transmitting ACK to the nodes.

Provided are a channel coordination method and apparatus. The method may be used by a first access point (AP) that is currently serving a terminal. In response to determining that a channel needs to be configured for a real-time service initiated by the terminal, the first AP detects a second AP that requires channel coordination. The first AP sends channel coordination request signalling to the second AP, wherein the channel coordination request signalling comprises a designated channel that the first AP requests to coordinate. In response to receiving first channel coordination feedback signalling, which is used for indicating to agree to coordinate the designated channel, sent from the second AP, the first AP determines, according to the first channel coordination feedback signalling, that the second AP agrees to coordinate the designated channel.

Apparatuses, systems, and methods for a wireless device and base station transmitting and/or receiving request to send (RTS) and clear to send (CTS) messages in 5G New Radio. The RTS/CTS messages may be comprised within a single self-contained mini slot. The RTS/CTS message design may provide for link adaptation and/or beamforming.

This disclosure provides a transmission processing method, a terminal, and a control node. The method includes: when first transmission collides with second transmission, performing collision processing on the first transmission and the second transmission according to a collision processing policy, where at least one of the first transmission and the second transmission is transmission performed based on a sidelink, and transmission modes of the first transmission and the second transmission are different.

Certain aspects of the present disclosure provide techniques for low power channel sensing for pedestrian user equipments (P-UEs). A method that may be performed by a UE (e.g., such as a P-UE) includes determining a level of channel congestion for a channel during a first sensing duration. The method includes determining a second sensing duration and a transmission duration based on the level of channel congestion for the channel determined from the first sensing duration. The method includes sensing the channel for the second sensing duration. The method includes transmitting on the channel for the transmission duration.

A data reporting method includes generating a data uploading token by a main network node, determining, from a plurality of data-uploading network nodes waiting for data uploading, a plurality of qualified network nodes having a data uploading qualification, allowing the qualified network nodes to compete for the data uploading token, and coordinating a data uploading operation with a winning network node of the qualified network nodes that obtained the data uploading token.

A method for handling checksum error in uplink data compression (UDC) in a wireless communication system includes: detecting, by user equipment (UE), a checksum failure; automatically controlling, by the UE, generation of a number of compressed protocol data units (PDUs) available for transmission at a Packet Data Convergence Protocol (PDCP) based on a package formation rate (PFT); and transmitting, by the UE, a number of compressed PDUs.

A packet sending method includes: receiving, by a first node, a first broadcast data packet sent by a second node; and if a sequence number of the first broadcast data packet equals 1 plus a sequence number of a latest data packet saved by the first node, and the first node does not receive, within a first preset time period, a first acknowledgement indication for the first broadcast data packet of the second node, sending, by the first node, a first broadcast acknowledgement packet when the first preset time period elapses, where the first broadcast acknowledgement packet includes the first acknowledgement indication, and the first acknowledgement indication includes the sequence number of the first broadcast data packet and an address of the second node. This method could resolve acknowledgement packet implosion while ensuring broadcast packet reliability of a wireless mesh network.
