摘要： Techniques and examples pertaining to codeword mapping in New Radio (NR) and interleaver design for NR are described. A processor of an apparatus receives, via a transceiver of the apparatus, a Physical Downlink Shared Channel (PDSCH) transmission from a network node of a wireless network. The processor maps one or more codeblocks of a codeword in the PDSCH transmission to a spatial layer group which is a subset of a plurality of spatial layers. The processor also performs receive processing for one or more codeblocks in the PDSCH transmission including by performing de-interleaving on a result from a channel interleaver or from an intra-codeblock interleaver that performs pseudo-random interleaving on systematic bits and parity bits of the one or more codeblocks and channel decoding. The processor transmits, via the transceiver, to the network node a feedback concerning the one or more codeblock and reporting a result of the channel estimation.

摘要： A processor of an apparatus selects a codebook from a plurality of codebooks embedded in a quasi-cyclic-low-density parity-check (QC-LDPC) code. The processor stores the selected codebook in a memory associated with the processor. The processor also encodes data using the selected codebook to generate a plurality of modulation symbols of the data. The processor further controls a transmitter of the apparatus to multiplex, convert, filter, amplify and radiate the modulation symbols as electromagnetic waves through one or more antennas of the apparatus. In selecting the codebook from the plurality of codebooks embedded in the QC-LDPC code, the processor selects the codebook according to one or more rules such that a small codebook requiring a shorter amount of processing latency for the encoding is selected for the encoding unless a larger codebook corresponding to a larger amount of processing latency for the encoding is necessary for the encoding.

摘要： A beamforming system synchronization architecture is proposed to allow a receiving device to synchronize to a transmitting device in time, frequency, and spatial domain in the most challenging situation with very high pathloss. A detector at the receiving device detects the presence of control beams, synchronizes to the transmission and estimates the channel response by receiving pilot signals. The detector has low complexity when exploiting the structure of the pilot signals. The detector consists of three stages that break down the synchronization procedure into less complicated steps. The detector accurately estimates the parameters required for identifying the transmit device and performing subsequent data communication.

摘要： Inter-cell coordination to avoid/minimize inter-cell interference in a beamformed mmWave network is proposed to enhance the detection probability of beam pattern indicator. A base station first obtains beacon signal transmission information of neighboring base stations. A plurality of beacon signals are transmitted over a plurality of control beams from the neighboring base stations. The base station then determines beacon signal transmission configuration by coordinating with the neighboring base stations to minimize inter-cell beacon signal interference. Each control beam is configured with a set of periodically allocated resource blocks and a set of beamforming weights. Finally, the base station transmits beacon signals based on the determined beacon signal transmission configuration over the plurality of control beams.

摘要： A user equipment (UE) receives and decodes a first erroneous transport block (TB) from a base station in a mobile communication network. The UE allocates a first soft buffer having a first buffer size. The first soft buffer is associated with a first HARQ process for storing the first TB. The UE then receives and decodes a second erroneous TB from the base station. The UE allocates a second soft buffer having a second buffer size. The second soft buffer is associated with a second HARQ process for storing the second TB. The UE releases a portion of the first soft buffer to be allocated as part of the second soft buffer. The dynamic buffer allocation method reduces mismatch between rate matching and soft buffer storing when the total number of HARQ processes is small. In addition, more HARQ processes can be supported when the corresponding TB size is small.
