Abstract:
1. In a wireless communication system configured to retransmit pending data until the data is acknowledged or until a maximum number of retransmissions are made, a method comprising: determining historical probability values associated with numbers of attempted transmissions of data; and for each of a plurality of pending data transmissions: determining a number of times transmission of the data transmission has been attempted on a channel in one or more preceding frames; determining, based on the historical probability values, a probability representing a likelihood that previously transmitted data will need to be retransmitted; and allocating power for the data transmission on the channel in a succeeding frame based upon the probability representing the likelihood that previously transmitted data will need to be retransmitted; wherein power is allocated for the data transmission on the channel based on probabilistically determining whether a corresponding transmission power requirement is needed for transmission and considering only transmission power requests probabilistically determined to require the corresponding transmission power requirement as candidates for data transmission power.
