摘要： A method performed by a network node for handling communication in a communication network. The network node configures a CSI reference resource as a function of a periodic transmission time of a downlink semi-persistent scheduling configuration or a group of downlink semi-persistent scheduling configurations and/or as a function of a dynamically scheduled physical downlink shared channel time.

摘要： A method of producing a set of coded bits from a set of information bits for transmission between a first node and a second node in a wireless communications system, the method comprises generating a codeword vector by encoding the set of information bits with a low-density parity-check code, wherein the codeword vector is composed of systematic bits and parity bits. The method comprises performing circular buffer-based rate matching on the generated codeword vector to produce the coded bits for transmission, wherein the circular buffer-based rate matching comprises puncturing a first plurality of systematic bits.

摘要： According to some embodiments, a method for use in a wireless transmitter comprises: determining an amount of data to transmit; determining a cyclic redundancy check (CRC) polynomial length based on the amount of data to transmit; encoding the data using a CRC of the determined polynomial length; and transmitting the encoded data. According to some embodiments, a method for use in a wireless receiver comprises: receiving encoded data from a wireless transmitter; determining an amount of data received in the encoded data; determining a CRC polynomial length based on the amount of data; and decoding the received encoded data using a CRC of the determined polynomial length. In particular embodiments, the data to transmit comprises control channel data or user data, and the encoding uses Polar codes or low-density parity check (LDPC) codes.

摘要： A method (500) performed by a UE. The method includes the UE receiving a configuration message that comprises positioning reference signal (PRS) resource configuration information defining a PRS resource configuration. The method also includes the UE receiving a trigger message transmitted by a base station, the trigger message comprising information for identifying the PRS resource configuration. The method also includes, after receiving the trigger message, the UE receiving a PRS transmitted by the base station according to the PRS resource configuration, wherein The PRS is a semi-persistently or an a-periodically transmitted DL reference signal.

摘要： A system and method for selecting a number of cyclic redundancy check bits in a communication system. In one embodiment, an apparatus operating in a communication system is configured to receive scheduling information from the communication system, and determine an information block length (K) and/or code rate (R) for a code block including a sequence of data bits from the scheduling information. The apparatus is further configured to determine a number of cyclic redundancy check (CRC) bits as a function of the information block length (K) and/or code rate (R) for the code block.
