    摘要： According to one aspect of the disclosure, a network node for adjusting a maximum channel code rate limit of a wireless device is provided. The network node includes processing circuitry. The processing circuitry includes a processor and a memory. The memory contains instructions that, when executed by the processor, configure the processor to: cause transmission, to the wireless device, of at least one data transmission coded at a maximum channel code rate that is one of less than and equal to a maximum channel code rate limit, receive at least one indication of reception of the at least one data transmission coded at the maximum channel code rate by the wireless device, and in response to receiving the at least one indication of reception associated with the at least one data transmission coded at the maximum channel code rate, modify the maximum channel code rate limit.

    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.

    摘要： A node including processing circuitry including a processor, and a memory, the memory containing instructions that, when executed by the processor, configure the processor to: determine a cluster of a plurality of cells, assign at least one ZP CSI-RS configuration to each of the plurality of cells of the cluster, assign to each cell in the plurality of cells of the cluster a respective NZP CSI-RS configuration in which each of the NZP CSI-RS configurations assigned to respective cells in the cluster partially overlapping the at least one ZP CSI-RS configuration, and cause a first cell of the plurality of cells of the cluster to transmit, within a subframe, based on the at least one ZP CSI-RS configuration and the NZP CSI-RS configuration assigned to the first cell.

    摘要： A method for using a high order modulation (HoM) mode for communications with a wireless device in a wireless communication network is provided. The method includes receiving downlink channel quality indicator (CQI) information from an uplink transmission of the wireless device and determining a downlink channel quality estimate from the CQI information. When a measurement of the downlink channel quality estimate satisfies the predetermined criteria for a first predetermined number of consecutive uplink transmissions from the wireless device, a downlink transmission mode of the wireless device is switched from a first modulation mode to the HoM mode.
