An access method and apparatus, and a communications system is provided One example method includes: The network control apparatus sends access configuration information, where the access configuration information configures an access manner of the at least one second apparatus, and the access manner includes a first access manner or a second access manner. A second apparatus in the at least one second apparatus sends access information of the second apparatus to the network control apparatus based on the access configuration information, where the access information requests access. The network control apparatus receives the access information from the second apparatus.

An access method and apparatus, and a communication system is provided One example method includes: sending resource configuration information, where the resource configuration information configures a first time-frequency resource used for access of a plurality of terminals; and receiving access information from at least one of the plurality of terminals on the first time-frequency resource, where the access information of the terminal includes at least one of first identity information or status information of the terminal, the first identity information identifies the terminal, and the status information indicates a status of the terminal.

Example methods of advanced DBVC for WiFi relate to one or more of avoiding beacon collisions between a repeater and a root AP, optimizing traffic flows based on buffers queued within hardware, optimizing TCP throughput through DPI and prioritization of TCP ACK packets, or optimizing transmissions through a trigger-based mechanism. An example method may include receiving a transmission from a root AP. The method may include obtaining a next root AP TBTT of a next beacon to be sent by the root AP from the transmission. The method may include determining an amount of time to delay a next repeater TBTT of a next beacon to be sent by a repeater to avoid conflict between the next root AP TBTT and the next repeater TBTT. The method may include delaying the next repeater TBTT based on the determined amount of time.

Methods, systems, and devices for transmitting a positioning reference signal over a channel within a window including a set of positioning reference signal transmission opportunities. A device may identify the window and perform a channel access procedure to access the channel during the window. Based on performing the channel access procedure, the device may obtain access to the channel and determine that a portion of the positioning reference signal transmission opportunities are remaining within the window. The device may transmit a positioning reference signal during one or more of the remaining positioning reference signal transmission opportunities. In some cases, the device may refrain from transmitting a positioning reference signal during a portion of a positioning reference signal transmission opportunity even if the device gains access to the channel during that portion of the positioning reference signal transmission opportunity.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.

A method is provided for enabling a User Equipment (102) to access services provided by a Radio Access Network by configuring the User Equipment (UE) with configuration information which comprises rules for selecting one or more of a plurality of access procedures to be used by the UE for accessing services provided by the Radio Access Network which may be a New Radio/5G network (101). Access procedures may include a grant-based procedure; a grant-free procedure and a fallback procedure to be used in cases of failure of an initial access attempt. The rules may be based on the type of service required by the UE such as; transmission and/or reception of data, transmission and/or reception of a voice call, a request for System Information.

According to an embodiment of the present disclosure, a terminal may store a time correction value acquired from an RA response message during an RRC layer connection to a base station, receive, from the base station, an uplink resource allocation message including an uplink resource allocated to the terminal, after the RRC layer connection to the base station is released, and when an RRC layer connection to the base station is determined, establish the RRC layer connection to the base station without transmitting an RA preamble message, on the basis of the stored time correction value and the allocated uplink resource.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may iterate a value of a channel access counter (CAC) to a trigger value based at least in part on configuring the value of the CAC. In some aspects, the first wireless communication device may utilize a channel access mechanism to select a set of time-frequency resources for a transmission of a packet based at least in part on iterating the value of the CAC to the trigger value. In some aspects, the first wireless communication device may transmit the packet to a second wireless communication device via the set of time-frequency resources based at least in part on utilizing the channel access mechanism to select the set of time-frequency resources for the transmission. Numerous other aspects are provided.

A control link switch method is employed by a wireless fidelity (WI-FI) multi-link device (MLD). The control link switch method includes: sending a request frame to another WI-FI MLD for requesting a switch process of switching a current control link to a new control link, and receiving a response frame from another WI-FI MLD. After the response frame is received, the new control link is selectively enabled at the WI-FI MLD.

A base station according to an embodiment of the present disclosure includes a generation unit (35) that generates a beacon including switching information (41) indicating whether to cooperatively use a frequency channel and a transmission unit (32) that transmits the beacon.
