Patent number: 11716746Abstract: Access, collision handling, and resolution for non-orthogonal multiple-access (NOMA) may be used. Fixed or dynamic group demodulation reference signal (DMRS) and multiple-access (MA) signature for NOMA retransmission may be used. A wireless transmit/receive unit (WTRU) may receive MAS information or DMRS information from a network entity. A WTRU may receive indication of the MAS information or DMRS information via a subgrouping-based scheme, a bitmap indication, or a binary threshold. A WTRU may receive an indication of a resource group size from the network entity. Based on the resource group size, the WTRU may determine whether the MAS information or the DMRS information is indicated via the subgrouping-based scheme or via the binary threshold scheme. The WTRU, based on how the MAS information or the DMRS information is indicated, may determine a resource to be used for a NOMA transmission. The WTRU may send the NOMA transmission using the determined resource.Type: GrantFiled: February 12, 2019Date of Patent: August 1, 2023Assignee: InterDigital Patent Holdings, Inc.Inventors: Kyle Jung-Lin Pan, Robert L.

Patent number: 11683125Abstract: Systems, methods, and instrumentalities are disclosed for interleaving coded bits. A wireless transmit/receive unit (WTRU) may generate a plurality of polar encoded bits using polar encoding. The WTRU may divide the plurality of polar encoded bits into sub-blocks of equal size in a sequential manner. The WTRU may apply sub-block wise interleaving to the sub-blocks using an interleaver pattern. The sub-blocks associated with a subset of the sub-blocks may be interleaved, and sub-blocks associated with another subset of the sub-blocks may not be interleaved. The sub-block wise interleaving may include applying interleaving across the sub-blocks without interleaving bits associated with each of the sub-blocks. The WTRU may concatenate bits from each of the interleaved sub-blocks to generate interleaved bits, and store the interleaved bits associated with the interleaved sub-blocks in a circular buffer. The WTRU may select a plurality of bits for transmission from the interleaved bits.Type: GrantFiled: May 17, 2022Date of Patent: June 20, 2023Assignee: InterDigital Patent Holdings, Inc.Inventors: Chunxuan Ye, Fengjun Xi, Sungkwon Hong, Kyle Jung-Lin Pan, Robert L.
