摘要： In a method of adjusting a modulation and coding scheme (MCS) level for a transmission on a communication channel between a base station and a mobile terminal, at the base station: a target value for an error metric is defined; the error metric is measured; an MCS offset based on a degree of deviation of the measurement of the error metric from the target value is determined; an indication of a channel quality measurement for the communication channel is received from the mobile terminal; a pre-adjusted MCS level corresponding to the indication of the channel quality measurement is determined using a fixed mapping between a set of channel quality levels and a corresponding set of MCS levels; an adjusted MCS level is determined by adding the MCS offset to the pre-adjusted MCS level; and the adjusted MCS level is assigned to the transmission.

摘要： The present invention provides a method and apparatus for improving wireless communication network performance and efficiency, based on detecting the occurrence of grant loss in relation to the transmission of scheduling grants to mobile terminals over a downlink control channel. Grant loss detection is based on detecting erasure events corresponding to the transmitted scheduling grants, and the incidence of grant loss with respect to a given mobile terminal can be tracked and used to compensate the control value(s) used for link adaptation of the downlink control channel, with respect to that terminal. Additionally, or alternatively, when a given grant is determined to be lost, a new grant is sent and the HARQ redundancy version is reset for the newly scheduled transmission.

摘要： A method and apparatus is provided for assigning resources for an acknowledgement channel, such as the PHICH in LTE systems. Acknowledgement channels for the mobile terminals are assigned to channel groups based on a predetermined assignment criteria. All acknowledgment channels in the same channel group receive acknowledgements on the same downlink resources (e.g., resource elements in OFDM system). A required transmit energy for each channel is determined. If the total required transmit energy for all channels exceeds an available transmit power, the allocated transmit energy for each channel is either scaled down so that the total actual transmit power for all acknowledgment channels is equal to the available transmit power, or some acknowledgment channels are not transmitted.

摘要： Methods of performing link adaptation in a wireless communication system for simultaneous transmission of codewords include selecting initial modulation and coding scheme (MCS) levels for the codewords, estimating a size ratio of the codewords, determining a number of scheduling blocks (SB) for the codewords with the initial MCS levels, and determining revised MCS levels for the codewords in response to the determined number of SBs. Transport block sizes are computed for the codewords, and it is determined if there is a need to increase the number of scheduling blocks in at least one of the codewords. If there is a need to increase the number of scheduling blocks in a codeword, scheduling blocks are added to the codeword, and the transport block size for the codeword is recomputed. The codewords are then simultaneously transmitted over different multiple input-multiple output (MIMO) communication channels using the same time and frequency resources.
