Abstract
Various techniques pertaining to coordinated multi-access point (CMAP) trigger frame (TF) extension schemes in wireless communications are described. An apparatus (e.g., an access point (AP)) transmits or receives a trigger frame (TF) that triggers a coordinated beamforming (CBF) transmission. The apparatus then participates in the CBF transmission. The TF provides an extension of time allowing each of one or more shared APs to finish recalculation of one or more steering matrixes for the CBF transmission before participating in the CBF transmission.
Claims20
A method, comprising:
- transmitting, by a processor of a sharing access point (AP), a trigger frame (TF) to one or more shared APs to trigger a coordinated beamforming (CBF) transmission;
- and
- participating, by the processor, in the CBF transmission with the one or more shared APs,
- wherein the TF provides an extension of time allowing each of the one or more shared APs to finish recalculation of one or more steering matrixes for the CBF transmission before participating in the CBF transmission.
A method, comprising:
- receiving, by a processor of a shared access point (AP), a trigger frame (TF) from a sharing AP that triggers a coordinated beamforming (CBF) transmission;
- and
- participating, by the processor, in the CBF transmission with the sharing AP,
- wherein the TF provides an extension of time allowing the shared AP to finish recalculation of one or more steering matrixes for the CBF transmission before participating in the CBF transmission.
An apparatus, comprising:
- a transceiver configured to communicate wirelessly;
- and
- a processor coupled to the transceiver and configured to perform operations comprising:
- transmitting or receiving, via the transceiver, a trigger frame (TF) that triggers a coordinated beamforming (CBF) transmission;
- and
- participating, via the transceiver, in the CBF transmission,
- wherein the TF provides an extension of time allowing each of one or more shared access points (APs) to finish recalculation of one or more steering matrixes for the CBF transmission before participating in the CBF transmission.
