摘要： There is provided a method performed by a wireless device for handling user data. The method comprises: receiving an index (such as a Transport Block Size (TBS) index) from a network node; determining a TBS based on the received index; determining a modulation order based at least on the determined TBS; and performing one of decoding and encoding the user data based at least on the determined modulation order.

摘要： There is provided a method performed by a wireless device for handling user data, wherein the user data are converted into codewords, each codeword having a first group of layers and a second group of layers. The method comprises: receiving an index from a network node, the index indicating a Transport Block Size (TBS) index, a Redundant Version (RV) and a differential modulation; determining a TBS based on the received index; determining a redundant version value based on the received index; determining a first modulation order for the first group and a second modulation order for the second group of a codeword, based on the differential modulation; and performing one of decoding and encoding the codeword based at least on the determined first and second modulation orders, the determined TBS and the determined redundant version value.

摘要： Systems and methods for enhanced link adaptation are provided. In some embodiments, a method of operation of a network node includes calculating an actual RE efficiency based at least in part on an actual TBS obtained from a specification. The TBS may be obtained from a specification based on LA result and actual buffer data volume. The method also includes determining a real BLER from a searchable repository, based on the actual RE efficiency and an actual BLER. The method may further include calculating an actual outer-loop adjustment (OLA) step based on the actual BLER. The method may further include a dynamic outer-loop up/down step adjustment based on the actual OLA step.

摘要： In one embodiment, a method of operating a radio access node is provided. The method comprises determining whether support from a secondary cell is required for a wireless device to communicate with the radio access node, and, in response to determining that support from the secondary cell is required, calculating a modified channel condition outer-loop value for the secondary cell; and using the modified channel condition outer-loop value in an initial activation decision step for the secondary cell. The initial activation decision step may comprise activating the secondary cell in response to determining that the sum of a device reported channel condition value and the modified channel condition outer-loop value is above an activation threshold. Corresponding devices, computer programs and radio access nodes adapted to carry out the methods provided are also disclosed.

摘要： Systems and methods for Multiple-Input and Multiple-Output (MIMO) rank reduction to improve downlink throughput are disclosed. A method of operation of a radio access node includes determining that an imbalance between parallel channels of a spatial multiplexing downlink transmission to a wireless device is greater than an imbalance threshold and/or that a Negative Acknowledgement (NACK) rate over time for the parallel channels of a spatial multiplexing downlink transmission reported by the wireless device is greater than a NACK rate threshold. The method also includes, in response to determining that the imbalance between the parallel channels is greater than the imbalance threshold and/or that the NACK rate is greater than the NACK rate threshold, performing a fast rank reduction for a next downlink transmission whereby a rank is reduced from a rank indicator reported by the wireless device to some lower rank. Reducing the rank may improve downlink throughput.
