Abstract
Methods and apparatus for determining a portion of a channel, e.g., a peer discovery channel, to use in a communications network, e.g., an ad hoc peer to peer network, are described. In the communication network, the channel includes a recurring set of time/frequency resources. A device monitors the congestion level and decides to use a whole channel or a fraction of a channel (e.g., ½. ¼) as a function of the congestion level. The device may change the fraction of the channel it occupies as the congestion level changes. The device broadcasts control information indicating the fraction of the channel it occupies. The device may be a mobile wireless terminal.
Claims20
A method of operating a communications device comprising:
- monitoring a recurring set of time and frequency resource units to determine a level of congestion;
- and
- determining a portion of a communications channel to be used by said communications device for transmission purposes based on the determined level of congestion.
A communications device comprising:
- means for monitoring a recurring set of time and frequency resource units to determine a level of congestion;
- and
- means for determining a portion of a communications channel to be used by said communications device for transmission purposes based on the determined level of congestion.
A computer program product for use in a communications device, the computer program product comprising:
- a computer readable medium comprising:
- code for causing at least one computer to monitor a recurring set of time and frequency resource units to determine a level of congestion;
- and
- code for causing said at least one computer to determine a portion of a communications channel to be used by said communications device for transmission purposes based on the determined level of congestion.
A communications device comprising:
- at least one processor configured to:
- monitor a recurring set of time and frequency resource units to determine a level of congestion;
- and
- determine a portion of a communications channel to be used by said communications device for transmission purposes based on the determined level of congestion;
- and memory coupled to said at least one processor.
