Abstract
A wireless communication device, a wireless communication system and a method of transmitting by a piconet controller (PNC) a poll request frame using beamforming techniques to one or more devices, wherein the poll request frame includes a time offset for sending a poll response frame by the device. The PNC receives the poll response frame with a channel bandwidth allocation request and dynamically allocating a channel bandwidth to the one or more devices according to the channel bandwidth allocation request.
Claims6
A method of communicating in a wireless communication network, comprising:
- transmitting, during a polling period, a first poll request frame addressed to a first device, wherein the first poll request frame includes a first time offset value for the first device to send a first poll response frame;
- transmitting, during the polling period, a second poll request frame addressed to a second device, wherein the second poll request frame includes a second time offset value for the second device to send a second poll response frame;
- receiving, during the polling period and at a time based on the first time offset value, the first poll response frame from the first device, the first poll response frame including a first time allocation request from the first device;
- receiving, during the polling period and at a time based on the second time offset value, the second poll response frame from the second device, the second poll response frame including a second time allocation request from the second device;
- transmitting, during a grant period subsequent to the polling period, a first grant frame to the first device granting a first scheduled period for communication by the first device based on the first time allocation request;
- and
- transmitting, during the grant period, a second grant frame to the second device granting a second scheduled period for communication by the second device based on the second time allocation request.
A wireless communications device, comprising:
- a transmitter configured to:
- transmit, during a polling period, a first poll request frame addressed to a first device, wherein the first poll request frame includes a first time offset value for the first device to send a first poll response frame;
- and
- transmit, during the polling period, a second poll request frame addressed to a second device, wherein the second poll request frame includes a second time offset value for the second device to send a second poll response frame;
- and
- a receiver configured to:
- receive, during the polling period and at a time based on the first time offset value, the first poll response frame from the first device, the first poll response frame including a first time allocation request from the first device;
- and
- receive, during the polling period and at a time based on the second time offset value, the second poll response frame from the second device, the second poll response frame including a second time allocation request from the second device;
- wherein the transmitter is further configured to:
- transmit, during a grant period subsequent to the polling period, a first grant frame to the first device granting a first scheduled period for communication by the first device based on the first time allocation request;
- and
- transmit, during the grant period, a second grant frame to the second device granting a second scheduled period for communication by the second device based on the second time allocation request.
