DATA COMMUNICATION METHOD AND APPARATUS: abstract simplified (18332269)

• This abstract for appeared for patent application number 18332269 Titled 'DATA COMMUNICATION METHOD AND APPARATUS'

Simplified Explanation

The abstract describes a method for data communication in a network. When a network node receives a data unit, it checks the identifier of the basic service set (BSS) in the data unit. If the BSS identifier is different from the node's own BSS identifier but the same as the identifier of an extended BSS to which a target relay belongs, the node determines if the data unit meets a specific condition for spatial reuse. If it does, the node competes for access to the network and communicates with a station in its own BSS, excluding the target relay.

Original Abstract Submitted

The present disclosure relates to data communication methods and apparatuses. One example method includes when receiving a physical layer protocol data unit (PPDU), obtaining, by a network node, a basic service set (BSS) identifier in the PPDUIf the BSS identifier in the PPDU is different from a first BSS identifier and same as a second BSS identifier, the network node determines whether the PPDU meets a preset spatial reuse condition, where the first BSS identifier is an identifier of a first BSS to which the network node belongs, the second BSS identifier is an identifier of an extended BSS to which a target relay belongs, and the target relay and the network node belong to the first BSS If the PPDU meets the preset spatial reuse condition, the network node contends for an access channel, and communicates with a station other than the target relay in the first BSS.
