Abstract
A transmission opportunity (TXOP) owner transfer request is received at a first communication device from a second communication device. The TXOP transfer request indicates that the second communication device is requesting to transfer ownership of a first TXOP to the first communication device, wherein the first TXOP is owned by the second communication device. In response to receiving the TXOP owner transfer request, the first communication device initiates a second TXOP which is owned by the first communication device.
Claims18
A method comprising:
- receiving, at a first communication device from a second communication device, a transmission opportunity (TXOP) owner transfer request that indicates that the second communication device is requesting to transfer ownership of a first TXOP to the first communication device, wherein the first TXOP is owned by the second communication device;
- in response to receiving the TXOP owner transfer request, initiating a second TXOP by the first communication device, wherein the second TXOP is owned by the first communication device, wherein initiating the second TXOP includes modifying one or more parameters of the first TXOP in connection with initiating the second TXOP, including i) modifying a frequency bandwidth of the first TXOP, and ii) modifying a duration of the first TXOP such that the modified duration is greater than a remainder of the duration of the first TXOP;
- and
- using, by the first communication device, the one or more modified parameters of the first TXOP for the second TXOP, including using i) the modified frequency bandwidth, and ii) the modified duration for the second TXOP.
A first communication device, comprising:
- a network interface device having one or more integrated circuits configured to:
- receive, from a second communication device, a transmission opportunity (TXOP) owner transfer request that indicates that the second communication device is requesting to transfer ownership of a first TXOP to the first communication device, wherein the first TXOP is owned by the second communication device,
- in response to receiving the TXOP owner transfer request, initiate a second TXOP, wherein the second TXOP is owned by the first communication device, wherein initiating the second TXOP includes modifying one or more parameters of the first TXOP in connection with initiating the second TXOP, including i) modifying a frequency bandwidth of the first TXOP, and ii) modifying a duration of the first TXOP such that the modified duration is greater than a remainder of the duration of the first TXOP, and
- use the one or more modified parameters of the first TXOP for the second TXOP, including using i) the modified frequency bandwidth, and ii) the modified duration for the second TXOP.
