摘要： A method in a base station for selecting a transport format is provided. The base station allocates resources to a User Equipment, UE.When a first criterion is fulfilled for the allocated resources, the base station estimates Signal-to-Interference-plus-Noise Ratio, SINR, by using a first gain offset. The first gain offset relates to a resource allocation according to the first criterion.When a second criterion is fulfilled for the allocated resources, the base station estimates SINR by using a second gain offset. The second gain offset relates to a resource allocation according to the second criterion.The base station then selects a transport format for the allocated resources based on the estimated SINR.

摘要： A wireless communication system includes first and second transceivers operable to transmit and receive signals over a communication channel using a plurality of modulation modes. A first signal is received which has been transmitted using a first modulation mode over the communication channel from the first transceiver to the second transceiver, and a first channel equalization characteristic for an equalizer of a first type for receiving the first signal at the second transceiver is determined from measurements of the communication channel. From the first channel equalization characteristic, a second channel equalization characteristic is determined for an equalizer of a second type for a second modulation mode. A measure of a difference between the second and the first channel equalization characteristics is determined, and the second modulation mode is selected for transmission over the communication channel from the first transceiver at least in part in dependence on the measure.

摘要： Embodiments of a system and method for transmitting data from an access point in a multiple user multiple input multiple output (MU-MIMO) system are provided. A first indication of signal quality (ISQ) is received at the access point from a first station and a second ISQ is received from a second station. The access point sets a first power level and a first modulation and coding scheme (MCS) for transmission of a first aggregated media access control (MAC) protocol data unit (A-MPDU) to the first station as a function of the first ISQ and an amount of payload data corresponding to the first A-MPDU. The access point also sets a second power level and a second MCS for transmission of a second A-MPDU as a function of the second ISQ and an amount of payload data corresponding to the second A-MPDU.

摘要： A base station that implements an improved link adaptation process that takes into account the fact that a certain reference signal (e.g., CSI-RS) may be seen as interference by certain wireless communication devices (WCDs). Accordingly, when the base station schedules a data transmission for the WCD to occur in a particular TTI and the base station is scheduled to transmit the CSI-RS during the same TTI, the base station will tend to select a more robust MCS for the data transmission to the WCD to counter effect the possible interference caused by the CSI-RS.

摘要： A method for selection of a particular modulation coding selection (MCS) from a plurality of available MCS selects a particular MCS after obtaining SNR_d, SNR_high, SNR_low, and if SNR_d>SNR_high, selecting the highest available MCS, and if SNR_d SNR_d>SNR_low, selecting MCS based on computing the function/table for each MCS according to the formula: f(MCS)=(1−PER(length_packet,MCS,SNR_d))/length_packet(packet_size,MCS), and thereafter selecting the MCS that maximizes the f(MCS) function. Further the neighboring MCS values are characterized for throughput in a throughput characterization step, and compared in throughput to the above determined throughput. In an embodiment of the invention, SNR_high, SNR_low are found by finding the SNR that satisfies: PER(length_packet,MCS_lowest,SNR_low)=PER_thresh PER(length_packet,MCS_highest,SNR_high)=PER_thresh Where PER_thresh is a design parameter, and MCS_lowest is the lowest MCS and MCS_highest is the highest available MCS.
