An example encoding method in a wireless communication system includes determining, for one or more code blocks of a transport block, that at least one of a plurality of criteria is met, wherein the plurality of criteria includes that a coding rate (R) is less than or equal to 1/4 or that a transport block size (TBS) is less than or equal to 3824 bits and the R is less than or equal to 2/3. The one or more code blocks are encoded using low-density parity-check (LDPC) base graph 2, wherein a maximum code block size is 3840 bits.

摘要： Systems and methods are disclosed herein that allow a radio access node to command a wireless device to clear parts of a soft buffer for a Hybrid Automatic Repeat Request (HARQ) process. In some embodiments, a method for a wireless device in a wireless communications system comprises receiving control information comprising information pertaining to whether the wireless device should partially clear a soft buffer for a HARQ process, deciding whether to partially clear the soft buffer for the HARQ process based on the information comprised in the control information, and partially clearing the soft buffer for the HARQ process upon deciding to partially clear the soft buffer for the HARQ process. In this manner, corrupted soft information can be cleared from the soft buffer while retaining uncorrupted soft information in the soft buffer.

摘要： A method performed by a network node (110) for estimating a convergence time of interference processing in a user equipment, UE (121), served by the network node (110) in a radio communications network (100) is provided. The network node has at least one Channel State Information, CSI, process configured for the UE. The network node receives, from the UE, at least one first CSI report based on signals transmitted on interference measurement resources of a first CSI process of the UE, wherein the first CSI process is in a first interference state. The network node then switches the first CSI process from the first interference state to a second interference state. After the switch, the network node receives, from the UE, at least one second CSI report based on signals transmitted on the interference measurement resources of the first CSI process of the UE, wherein the first CSI process is in the second interference state. Then, the network node estimates the convergence time of the interference processing in the UE using the received at least one first CSI report and the received at least one second CSI report. A network node (110) for estimating a convergence time of interference processing in a user equipment, a computer program and carrier are also provided.

摘要： A method performed by a network node (110) for enabling transmissions to a user equipment, UE (121), from transmission points, TPs, in a coordination cell area (101-105, 07) in a radio communications network (100) is provided. The network node (110) configures two or more TPs in the coordination cell area (101-105, 107) not currently serving the UE (121) to transmit signals on interference measurement, IM, resources of two or more Channel State Information, CSI, processes of the UE (121) according to three or more different interference states. The network node (110) then receives, from the UE (121), CSI reports based on the transmitted signals on the IM resources of the two or more CSI processes of the UE (121). After receiving the CSI reports, the network node (110) estimates one signal quality value for each of the three or more different interference states of the transmitted signals and at least one further signal quality value corresponding to at least one interference state that is not part of the three or more different interference states of the transmitted signals based on the received CSI reports of the two or more CSI processes. A network node (110) for enabling transmissions to a UE (121) from TPs in a coordination cell area (101-105, 107), a computer program and a carrier are also provided.

摘要： According to certain embodiments, a method is provided for fast layered decoding for Low-density Parity-Check (LDPC) codes with a Parity-Check Matrix (PCM) that includes at least a first layer and a second layer. The method includes reading, from a memory, Variable Node (VN) soft information, wherein the VN soft information is associated with a message from a VN to a Check Node (CN) of the second layer of the PCM. A new CN to VN message is calculated from the CN of the second layer of the PCM. New VN soft information is calculated for the VN. The new VN soft information is calculated based on the VN soft information and a new CN to VN message from a CN of the first layer to the VN and an old CN to VN message from the CN of the first layer to the VN such that the updating of new VN soft information is delayed by at least one layer. The fast layered decoding has lower decoding latency and utilizes the decoding hardware more efficiently than standard layered decoding techniques. This may be achieved by keeping the memory access and processing hardware units active simultaneously to avoid excess decoding latency. More specifically, certain embodiments may carry out memory access and computation process simultaneously, without any effort to make the row layers mutually orthogonal to each other. Another technical advantage may be that the proposed decoding algorithm adjusts the LLRs to partially account for deviations from the layered decoding due to non-orthogonal rows.
