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： 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： Embodiments include methods for configuring uplink (UL) resources for a cell of a wireless network. Such methods include configuring each of a plurality of UL resources for the cell as one of the following: a static physical UL control channel (PUCCH) resource, a static physical UL shared channel (PUSCH) resource, or a dynamic resource, being initially configured as a PUSCH resource. Such methods include, when a number of UEs that are connected to the cell increases above a first threshold, reconfiguring one of the dynamic resources as a PUCCH resource according to a first PUCCH format. Such methods include, when a number of UEs connected to the cell that meet at least one criteria associated with downlink (DL) data increases above a second threshold, reconfiguring one of the dynamic resources as a PUCCH resource according to a second PUCCH format. Other embodiments include network nodes configured to perform such methods.

摘要： A first network node configured to communicate with a second network node and a wireless device, WD, is described. The first network node includes processing circuitry configured to determine a link profile of a communication link between the first network node and the second network node and determine a set of time offset values. Each time offset value indicates a time delay between a downlink transmission from the second network node and a corresponding uplink transmission from the WD to the first network node. The set of time offset values are determined based at least in part on the link profile.

摘要： A method and network entity for enabling higher order modulation (HOM) mode support for HOM capable wireless devices. The method includes determining a legacy mode power offset value for HOM mode capable wireless devices in legacy modulation mode and calculating a power headroom value for sending downlink data to the HOM mode capable wireless devices. When the power headroom value exceeds a threshold value, the HOM mode support for the HOM mode capable wireless devices is enabled using the identified legacy mode power offset value. When the power headroom value does not exceed the threshold value, and a HOM mode power offset value is available, the HOM mode power offset value being less than the legacy modulation mode power offset value, the HOM mode support for the HOM mode capable wireless devices is enabled using the HOM mode power offset value.

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.

摘要： Disclosed techniques provide for selection of the codebook type used by a User Equipment (UE) (12), for Hybrid Automatic Repeat reQuest (HARQ) feedback to a wireless communication network (10) in multi-connectivity scenarios. The particular HARQ-ACK codebook type selected for use by the UE (12) depends on a delay associated with transferring HARQ feedback received from the UE (12) for a secondary cell (34) to the processing entity (42) that is responsible for downlink transmission control in the secondary cell (34). For example, the HARQ feedback is received via a first or primary cell (34) and then transferred from there to a radio network node or other geographically-remote circuitry that performs the downlink transmission control for the secondary cell (34).

摘要： A method and apparatus are disclosed for non-collocated SCell selection for NR CA. In one embodiment, a network node is configured to estimate a first throughput for the WD at a first candidate secondary cell, the estimated first throughput being based on a measured inter-network node delay between the network node and a first network node supporting the first candidate secondary cell, the network node supporting a primary cell; and determine whether to select the first candidate secondary cell for the WD based on the first estimated throughput. In another embodiment, a network node is configured to determine an average amount of time resources associated with a Hybrid Automatic Repeat reQuest, HARQ, process exhaustion experienced by WDs connected to the first candidate secondary cell and primary cells with an inter-network node delay, d; and report the average amount.
