Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-COT resources. The UE may then transmit to a second UE using the set of transmission resources.

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.

Embodiments herein relate to a method, performed by a network node (110) in a wireless communication system (100), for handling resource allocations for a first User Equipment, UE (120a) out of a set of UEs (120). Each of the UEs (120) in the set of UEs 5(120) has a different pre-configured frequency allocation for cyclic transmissions, such as cyclic UL and/or DL transmissions. The network node (110) determines, based on a data arrival pattern, such as e.g. a packet arrival time, of the cyclic UL transmissions for each of the UEs in the set of UEs (120), one or more TTIs, where a collision between transmissions to and/or from two UEs (120) out of the set of UEs (120) may occur. The 10 network node (110) reconfigures the frequency allocation for a first UE (120a) of the two UEs (120) to overlap, at least partly, with the frequency of a second UE (120b) of the two UEs (120) for the TTIs other than the TTIs where the collision between the transmissions to and/or from the first and the second UEs (120a, 120b) may occur. Embodiments herein further relate to a method, performed by the first UE (120a) out of the set of UEs (120) in 15 the wireless communication system (100), for handling resource allocation for the first UE (120a) out of the set of UEs (120).

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.

Example uplink transmission resource requesting methods and apparatus are described. One example method includes a terminal determines that a collision occurs when the terminal sends a first request to a network device, where the first request is used to request the network device to schedule an uplink transmission resource for the terminal. The terminal adjusts a manner of sending the first request according to a preset rule. In embodiments of this application, the terminal may request the uplink transmission resource from the network device by using the first request.

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.

This disclosure relates to transferring data segments, and includes a method and apparatus for performing a random access channel (RACH) procedure with a network entity for transferring a first portion of a plurality of data segments from a user equipment (UE) to the network entity during a radio resource control (RRC) inactive state, wherein the RACH procedure comprises receiving a physical downlink control channel (PDCCH) configuration from the network entity, the PDCCH configuration including an identified search space; and monitoring a PDCCH for PDCCH candidates addressed by a UE-specific network identifier in the identified search space for dynamic scheduling information that schedules a second portion of the plurality of data segments.

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.
