Methods and apparatus for protection of multi-user (MU) transmission are described herein. An apparatus includes a receiver, a transmitter and a processor. The receiver and the processor detect a trigger frame for an uplink (UL) multi-user (MU) transmission. The processor and the transmitter generate and send a frame in response to the trigger frame and transmit channel availability information for a plurality of channels in response to the trigger frame. The receiver and the processor detect data in a resource unit (RU) of a downlink (DL) MU physical layer (PHY) protocol data unit (PPDU) on one of the plurality of channels. The one of the plurality of channels is based on the transmitted channel availability information.

A communication device including: a central processing unit (CPU), configured to select a first target channel from a plurality of candidate target channel and configure a first non-dynamic frequency selection (non-DFS) channel as an in-use channel, in response to the first target channel being a DFS channel; a channel availability check (CAC) circuit, coupled to the CPU and configured to perform a first CAC for the first target channel to generate a first CAC result, in response to the first target channel being the DFS channel; and a communication circuit, coupled to the CPU and configured to perform at least one communication operation on the first non-DFS channel during the first CAC and perform the at least one communication operation on the first target channel, in response to the first CAC result being successful.

Disclosed are systems and methods that provide a computerized network management framework that adaptively configures a network at a location to ensure connectivity and / or network services are maintained. The disclosed framework enables the implementation of multi-link operation (MLO) functionality within WiFi 7 enabled networks to implement non-disruptive channel availability check (CAC) capabilities. The framework can utilize MLO backup / redundant links that can mitigate network disruptions in service / connectivity for client devices that are WiFi 7 capable and utilize MLO functionality by diverting network traffic to an activated MLO link while an available channel / radio (e.g., 5 GHz) is used to perform the CAC operations.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) can identify, from one or more channel sensing modes for sensing channel availability of a sidelink channel, a channel sensing mode for a communication on the sidelink channel, each of the one or more channel sensing modes being associated with a set of resources. The UE can transmit the communication on the sidelink channel in accordance with the channel sensing mode using resources selected from the set of resources associated with the channel sensing mode. Numerous other aspects are provided.

The invention discloses a cooperative channel selection method and system, electronic equipment and a storage medium, and belongs to the technical field of communication. Comprising the following steps: acquiring a first reference availability check result of a candidate channel from a plurality of channels; determining whether the candidate channel satisfies a preset residence condition according to the first reference availability check result; and under the condition that the candidate channel meets the preset resident condition, skipping the availability check of the candidate channel, and taking the candidate channel as a resident target channel. According to the invention, channel selection can be assisted by means of the first reference availability check results obtained by multiple channels, and unnecessary channel availability check (CAC) is avoided as much as possible, so that the efficiency of dynamic frequency selection is improved, and the user experience is improved.

The present disclosure provides a node in a wireless communication system and methods performed by the same. A method performed by a first node in a wireless communication system, including: performing dynamic spectrum allocation based on a first model; and transmitting a dynamic spectrum allocation result to a second node, wherein the dynamic spectrum allocation result includes cell channel indication information and cell channel availability indication information, wherein the cell channel indication information includes indicators of one or more channels to which a cell is allocated, and wherein the cell channel availability indication information includes identification information indicating whether the one or more channels are available.

The invention provides a channel availability maintenance method, electronic equipment and a program product, and relates to the technical field of computers. The method comprises the following steps: acquiring a channel response message returned by a called target channel; when the channel response message carries call response information of a service level, judging whether the channel response message carries a target error code or not, and obtaining a judgment result; wherein the target error code belongs to a business level error code list of failure information needing to be counted; and performing statistics on failure information of the target channel according to the judgment result, and maintaining the availability of the target channel according to the failure information obtained through statistics so as to perform channel selection based on the availability of the channel during next call. The method and the device are used for solving the problem that channel availability of a service level cannot be solved in the prior art.

Increased channel availability may be provided. A computing device may receive radio channel information comprising a radio channel to operate within and an incumbent indication indicating whether an incumbent is using the radio channel. Next, power to operate a radio at may be determined based on the incumbent indication. When the incumbent indication indicates an incumbent is present on the radio channel, determining the power to operate the radio based on the incumbent indication comprises: i) determining a first power level for subcarriers in the radio channel that are non-overlapping with a portion of the radio channel used by the incumbent; and ii) determining a second power level for subcarriers in the radio channel that are overlapping with the portion of the radio channel used by the incumbent wherein the first power level is greater than the second power level. The radio may then be operated at the determined power.

Certain aspects of the present disclosure provide techniques for wireless communications by an apparatus, such as a user equipment (UE). The method includes receiving, from a network entity, a message comprising physical random access channel (PRACH) adaptation information, wherein the PRACH adaptation information is included in one of: one or more reserved bits of the message, or a paging early indication (PEI) of the message; and performing a random access channel (RACH) procedure based on the PRACH adaptation information.
