摘要： A method, information processing system, and base station for reshaping power profiles in Orthogonal Frequency Division Multiple Access (OFDMA) symbols. The method includes monitoring a scheduler (116) at a base station (110) for a modulation and coding scheme selection. Determining that the scheduler (116) selected a modulation and coding scheme. Identifying at least one information element (220) within the symbol. Determining, in response to the identifying, a channel connection (210) associated with the at least one information element (220). Determining a channel condition associated with the channel connection (210). Reshaping a power profile associated with the one information element (220). The reshaping decreases power made available to the channel connection (210). Reshaping, in response to the channel condition being less than the channel condition threshold, the power profile associated with the at least one information element (220) so that power made available to the channel connection (210) is increased.

摘要： In an OFDM communication system, a mobile station provides a radio access network (RAN) a channel quality metric second order statistic, in one embodiment a signal to noise plus interference power ratio (SINR) second order statistic and in particular an SINR standard deviation and/or variance, along with a mean channel quality metric, that is, a mean SINR. By providing both a mean channel quality metric and a channel quality metric second order statistic, the communication system permits the RAN to create a more accurate fading profile of an associated air interface, and in particular a downlink of the air interface, thereby facilitating an improved scheduling decision over the prior art and assuring that a packet has a higher probability to go through a downlink channel without too many retransmissions.

摘要： A technique for operating a wireless communication device includes assigning re-transmission identifiers, such as hybrid automatic repeat request (HARQ) channel identifications, automatic repeat request (ARQ) channel identifications, and ARQ Identifier Sequence Numbers, to at least a first re-transmission identifier group and a second re-transmission identifier group, wherein each re-transmission identifier group is associated with a different quality of service parameter. The technique identifies whether a committed quality of service is met for a connection based on whether a communication on the connection is associated with the first re-transmission identifier group or the second re-transmission identifier group.
