A mobile station for performing communication using component carriers belonging to different base stations includes a reconnection determination unit configured to determine a trigger to initiate a reconnection procedure; a reconnection request unit configured to generate a reconnection request using at least one of information about a primary cell and information about a secondary cell; and a transmission unit configured to transmit the reconnection request.

Apparatuses, methods, and systems are disclosed for resource reservation. One apparatus (200) includes a receiver (212) that receives (802) an indication of resource reservation for uplink communication. The indication is based on information reported from a first remote unit. The apparatus (200) also includes a processor (202) that determines (804) a resource based on the indication. The apparatus (200) includes a transmitter (210) that transmits (806) data on the resource.

Location-aware spatial reuse may be provided. First, an Overlapping Basic Service Set (OBSS) transmission to be received at a device may be detected by a first Access Point (AP). Then the location of the device may be determined. Next, based on the determined location, it may be determined that the device is out of range of the first AP. Then, in response to determining that the device is out of range of the first AP, the first AP may perform an OBSS Packet Detect (PD) based Spatial Reuse (SR) transmission without reducing a transmit (Tx) power for the transmission.

Efficient opportunistic communications in integrated access and backhaul (IAB) frameworks are provided allowing scheduling nodes and scheduled nodes to communicate within an allocated set of resources based on a different configuration than for non-opportunistic communications using a different set of resources. An additional set of available resources may be allocated for coordinated communications between a parent IAB-node and the child IAB-node. Resources within this available set are associated with a first configuration, and when prior coordination exists, the parent IAB-node and child IAB-node may communicate based on this first configuration over this available set of resources. However, when prior coordination does not exist, the parent IAB-node and child IAB-node may opportunistically communicate over the allocated set of resources based on a second configuration different than the first configuration. Using different configurations, power may be conserved and resources managed more efficiently in opportunistic communications where unsuccessful transmissions may be more likely.

A channel allocation method and a related apparatus are disclosed. The method is for reducing a quantity of access points whose channels are to be switched and reducing an amount of calculation for channel switching. The method includes: obtaining interference degrees of a plurality of access points; and performing partial channel allocation based on the interference degrees. The partial channel allocation includes: retaining an operating channel of an access point in a first access point set, and reallocating an operating channel to an access point in a second access point set. The first access point set includes an access point whose interference degree is lower than a target degree in the plurality of access points, and the second access point set includes an access point whose interference degree reaches the target degree in the plurality of access points.

Certain aspects relate to methods and apparatus for wireless communication. The apparatus generally includes a processing system configured to generate a first frame including an indication of unused resources in a first basic service set (BSS) available to be shared with one or more wireless nodes in one or more second BSSs. The apparatus also includes a first interface configured to output the first frame for transmission to the one or more wireless nodes.

Aspects are described for use in wireless communications. Nodes may provide wireless access to wireless devices in different coverage areas. The nodes may transmit messages having time interval allocation bitmaps that indicate reduced transmission power time intervals. The reduced transmission power time intervals may be different for different nodes.
