Abstract: Disclosed is a method of setting conditions for an access point (AP) to be included in an AP candidate set of a coordinating AP for a transmission opportunity (TXOP), including setting a first primary channel of the AP as part of the AP candidate set of the coordinating AP within a basic service set (BSS) operating bandwidth of the coordinating AP, and coordinating AP updates in the AP candidate set when a coordinated AP that is part of the AP candidate set performs a channel switch to a second primary channel operating on a different bandwidth stream than a bandwidth stream of the first primary channel.

Abstract: Systems and methods for managing use of power of a wireless communication device configured to communicate over a plurality of radio links. A criterion is detected, and one of the plurality of radio links is selected as a selected radio link based on detecting the criterion. Operation of the selected radio link is switched from a first operating mode to a second operating mode, and operation of one or more remaining radio links of the plurality of radio links is disabled. In response to switching operation of the selected radio link to the second operating mode, the selected radio link oscillates between an awake state and an asleep state. Radio traffic information for the plurality of radio links is received, via the selected radio link, during the awake state.

Abstract: An apparatus and a method for allocating a multiple resource unit (RU) for a user in a wireless local area network (WLAN) system are provided. A transmission device of the WLAN system includes a transceiver that generates a physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a preamble and a payload and transmitting the generated PPDU to at least one receiving device and a processor controlling the transceiver. The preamble includes a plurality of training fields and a plurality of signaling fields. Resource unit (RU) allocation information on the at least one receiving device is included in one of the plurality of signaling fields. The RU allocation information includes a first subfield indicating an arrangement of RUs in a frequency domain corresponding to the PPDU and a second subfield indicating a portion of the RUs to be combined to form a multiple RU.

Abstract: Method for non-iterative singular-value decomposition (SVD). The method includes receiving, by receiver, signal; determining, by channel matrix generator, channel matrix for received signal, where channel matrix has dimension Nrx×Ntx, Nrx is number of receive antennas, Ntx is integer indicating number of transmit antennas; reducing, by singular-value decomposer, dimension of channel matrix to min(Nrx,Ntx)×min(Nrx,Ntx), where min( ) is function that returns coefficient with minimum value; performing, by singular-value decomposer, SVD on dimension-reduced channel matrix to determine singular vectors and corresponding coefficients that maximize singular values of singular vectors; outputting result of SVD based on at least one of when dimension of dimension-reduced channel matrix is less than or equal to 2 and when two greatest singular values of corresponding singular vectors are determined; when result of SVD not output, subtracting, by singular-value decomposer, singular vectors from dimension-reduced channel matrix to reduce rank and returning to performing SVD.
