Abstract: A device provides a soft access point in, for example, a wireless network. The device sends, to an access point, a resource request message that includes cluster information about a cluster of network units connected to the device. The access point allocates first resources for communications within the cluster according to the cluster information, and sends to the device a resource allocation message specifying the first resources. The device uses the first resources for communications within the cluster.

Abstract: An apparatus for deriving a submatrix {tilde over (G)}−1 is described. The apparatus for deriving a submatrix {tilde over (G)}−1 is configured to select an N-elements-column and an N-elements-row of an N×N-Matrix G or G−1. The apparatus for deriving a submatrix {tilde over (G)}−1 is configured to rearrange the selected column to the rightest column and the selected row to the lowest row of G or G−1 so as to generate a N×N-matrix Gp or Gp−1. The apparatus for deriving a submatrix {tilde over (G)}−1 is configured to calculate a submatrix {tilde over (G)}−1 by G ~ - 1 = A - AbcA d - 1 + c T  Ab , wherein the parameters (N−1)×(N−1)-submatrix A, b, d, c are obtained from the Gp or the Gp−1; wherein G p = [ G ~ b c T d ] ,  G p - 1 = [ A b ~ c ~ T d ~ ] .

Abstract: A sharing access point, AP, is configured to share at least a portion of a transmission opportunity, TXOP, with one or more shared APs within a Multi-AP, M-AP, set for participating in a coordinated transmission. The sharing AP comprises a processing circuitry configured to generate a M-AP trigger frame; and a communication interface configured to transmit the M-AP trigger frame to a shared AP within the M-AP set. The M-AP trigger frame is configured to solicit the shared AP to initiate a coordination-related procedure with one or more non-AP stations associated with the shared AP and/or with one or more OBSS non-AP stations associated with one or more further shared APs within the M-AP set and to transmit a completion notification frame to the sharing AP. The communication interface is further configured to receive from the shared AP the completion notification frame indicating the completion of the coordination-related procedure.

Abstract: The method includes: receiving, by a second transmit end, policy information sent by a first transmit end, where the second transmit end belongs to a second BSS, the first transmit end is a transmit end that is in a first basis service set and that transmits data by using a first link, and the policy information is used to indicate a condition that the second transmit end needs to satisfy to transmit data by using a second link, or used to indicate whether the second transmit end is allowed to transmit data by using a second link; and determining, by the second transmit end based on the policy information, whether to transmit data by using the second link. According to the wireless communication method, a spatial reuse transmission policy can be adjusted dynamically based on an actual situation of a current network. This improves a system throughput.

Abstract: A device on a wireless network generates duration data for determining a duration of a time interval. A transmission is then instructed, by the device, to transmit the duration data and a downlink payload including an aggregated Media Access Control (MAC) layer data unit, the downlink payload being transmitted on first subcarriers. The transmission also includes a trigger that configures the at least one other device on the network to transmit an uplink payload within the time interval, and during at least part of the transmission of the downlink payload, on second subcarriers that are at different frequencies to the first subcarriers.

Abstract: The invention relates to an apparatus for selecting candidates in a K-Best algorithm of a MIMO decoder. The K-Best algorithm uses a layered structure comprising a first layer and subsequent layers. In each subsequent layer 2L candidates are selected by iteratively carrying out a selection step, wherein in the selection step the apparatus is configured to calculate and select at least two candidates having minimum distance values of a candidate group, and after each iteratively carried out selection step, the selected at least two candidates are sent to a further subsequent layer for iteratively generating a further candidate group of 2L candidates in the further subsequent layer.
