Abstract
Systems and methods for communicating in a wireless communication system are described. One implementation is provided for effectively resetting stations within a wireless communication system. For example, a signal indicating the end of a contention free period may be transmitted from a device requesting the contention free period to another peer device or an access point. The peer device or access point may be configured to then transmit the occurrence of the end of the contention free period to other devices of the wireless communication system.
Claims61
A method of communicating in a wireless communication system comprising:
- receiving, from an access point, a first signal requesting a start of a contention free period for a first communication device;
- after the first signal is received, transmitting, to a plurality of communication devices, a second signal including an indication of the start of the contention free period;
- receiving, from the access point, a data signal in response to transmitting the indication of the start of the contention free period;
- transmitting, to the access point, an acknowledgement signal in response to receiving the data signal;
- receiving, from the access point, a third signal in response to transmitting the acknowledgement signal, the third signal including an indication of an end of the contention free period and including a duration indicating an amount of time to wait before transmitting a fourth signal;
- and
- after the indication of the end of the contention free period is received, transmitting the fourth signal including the indication of the end of the contention free period to the plurality of communication devices based on the received third signal and the duration.

- after the first signal is transmitted, receiving a second signal including an indication of the start of the contention free period;
- transmitting, from the access point, a data signal in response to receiving the indication of the start of the contention free period;
- receiving, at the access point, an acknowledgement signal in response to transmitting the data signal;
- transmitting, from the access point, a third signal in response to receiving the acknowledgement signal, the third signal including an indication of an end of the contention free period and including a duration indicating an amount of time to wait before transmitting a fourth signal;
- and
- after the indication of the end of the contention free period is transmitted, receiving, based at least in part on the duration, a fourth signal including the indication of the end of the contention free period including information from the transmitted third signal.

A wireless communication device comprising:
- a receiver configured to receive an indication of a contention free period end for a contention free period from a device having requested the contention free period, the indication of the contention free period end being received in response to transmitting an acknowledgement signal in response to receiving a data signal, the data signal received in response to transmitting an indication of a start of the contention free period;
- a processor configured to generate a first signal including a duration, the first signal instructing a second wireless communication device to transmit a signal after the transmission of the first signal, the signal including an indication of the end of the contention free period based on the first signal and the duration, the duration indicating an amount of time to wait before transmitting the indication of the end of the contention free period;
- and
- a transmitter coupled with the processor and configured to transmit the first signal to the second wireless communication device.

A wireless communication device comprising:
- a receiver configured to:
- receive an initial contention free period end signal for a contention free period, the initial contention free period end signal being received in response to transmitting an acknowledgement signal in response to receiving a data signal, the data signal received in response to transmitting an indication of a start of the contention free period, and
- receive a first signal from a second wireless communication device including an indication of an end of the contention free period and including a duration indication an amount of time to wait before transmitting a second signal, the initial contention free period end signal received at a first point in time preceding a second point in time when the indication of the end of the contention free period is received;
- a processor coupled with the receiver and configured to generate the second signal, the second signal including the indication of the end of the contention free period and being based at least in part on the indication of the end of the contention free period and the duration indication;
- and
- a transmitter coupled with the processor and configured to transmit the second signal, after the transmission of the indication of the end of the contention free period, to a plurality of wireless communication devices based at least in part on the first signal and the duration.
