摘要： Methods and apparatus for supporting peer to peer and infrastructure, e.g., cellular, communication in a multimode device which can operate in a cellular system are described. Methods and apparatus for supporting peer to peer devices are also described. Peer to peer communication occurs within a switching time period during which infrastructure signaling does not occur and devices switch between an uplink and a downlink mode of infrastructure operation. The time period set for the switching time period is intentionally set larger, e.g., 10, 50, 100 or even more times larger than that required based on maximum cell size. Thus, a peer to peer communications period can be introduced into a TDD system and use the same frequency band as the TDD system in a manner that can remain compliant with a cellular communications protocol which allows for a switching time period, e.g., set in the system by a parameter.

摘要： Aspects of the present disclosure relate to low density parity check (LDPC) coding utilizing LDPC base graphs. Two or more LDPC base graphs may be maintained that are associated with different ranges of overlapping information block lengths. A particular LDPC base graph may be selected for an information block based on the information block length of the information block. Additional metrics that may be considered when selecting the LDPC base graph may include the code rate utilized to encode the information block and/or the lift size applied to each LDPC base graph to produce the information block length of the information block.

摘要： Certain aspects of the present disclosure generally relate to techniques for puncturing of structured low density parity check (LDPC) codes. A method for wireless communications by wireless node is provided. The method generally includes encoding a set of information bits based on a LDPC code to produce a code word, the LDPC code defined by a matrix having a first number of variable nodes and a second number of check nodes, puncturing the code word to produce a punctured code word, wherein the puncturing is performed according to a first puncturing pattern designed to puncture bits corresponding to one or more of the variable nodes having a certain degree of connectivity to the check nodes, and transmitting the punctured code word.

摘要： Various aspects described herein relate to techniques for rate matching and interleaving in wireless communications (e.g., 5G NR). In an example, a method described herein includes encoding one or more information bits to generate a first codeblock, rate matching the first codeblock to generate a second codeblock, segmenting, using bit distribution, the second codeblock into one or more sub-blocks each having a plurality of bits. The method further includes interleaving the plurality of bits on each of the one or more sub-blocks, concatenating, using bit collection, the one or more sub-blocks to generate a third codeblock in response to the interleaving, and transmitting a signal using the third codeblock.

摘要： Certain aspects of the present disclosure generally relate to methods and apparatus for decoding low density parity check (LDPC) codes, and more particularly to a deeply-pipelined layered LDPC decoder architecture for high decoding throughputs. Accordingly, aspects of the present disclosure provide techniques for reducing delays in a processing pipeline by, in some cases, relaxing a dependency between updating bit log likelihood ratios (LLRs) and computing a posteriori LLRs.
