摘要： A network element (230) for communicating with a wireless communication unit (214) in a communication cell (200) of a communication system (200) comprises a receiver arranged to perform a frequency sweep across a plurality of operational frequencies. Signal processing logic (255), operably coupled to the receiver, processes the received signals from the frequency sweep and providing an estimate of a level of interference at a number of frequency carriers of the swept frequencies. The signal processing logic (255) is capable of determining whether a transmit power level at a frequency selected from the processed frequency sweep satisfies at least one predetermined quality criterion of the communication system (200). A transmitter (270) is arranged, upon initial activation of the network element (230), to transmit to a wireless communication unit at the determined transmit power level.

摘要： Methods and apparatus operative in a wireless communications system divide a communications resource available for performing information transmission and retransmission operations into a plurality of communication resource units. Channel quality information is used to rank each of the communication resource units in terms of channel quality. The communication resource units are divided into a first group having better channel quality and a second group having worse channel quality. The first group of communication resource units having better channel quality is used to transmit new information to a first group of receiving communication devices. The second group of communication resource units having worse channel quality is used to retransmit information to a second group of receiving communication devices. In such a manner simultaneous scheduling of information transmission and retransmission may be accommodated in a 3GPP LTE OFDM based wireless communications system.

摘要： Methods, apparatus and computer program products implement frequency domain packet scheduling in a fractional load situation by detecting a fractional load situation in a wireless communications network; receiving information indicative of signal conditions in a cell; using the information indicative of signal conditions in the cell to determine physical resource blocks in use in a nearby cell; determining how many physical resource blocks are need to perform packet transmission operations in dependence on packet traffic in the cell; selecting particular physical resource blocks to be used to perform initial packet transmission operations in the cell downlink so as to avoid those physical resource blocks in use in the nearby cell; and when selecting physical resource blocks to perform future packet transmission operations in the cell downlink, favoring those physical resource blocks used to perform initial packet transmission operations.
