Publication number: 20230189344Abstract: This disclosure relates to Random Access (RA) procedures in communication networks, and in particular relates to the 4-step RA procedure and the 2-step RA procedure. The techniques described herein more specifically relate to the content of a channel state information report in a random access procedure. A method performed by a wireless device in a random access, RA, procedure comprises performing measurements of one or more reference signals transmitted by abase station. The method further comprises sending a first message to the base station in a Physical Uplink Shared Channel, PUSCH. The first message comprises a Channel State Information, CSI, report comprising information based on the measurements of the one or more reference signals.Type: ApplicationFiled: May 14, 2021Publication date: June 15, 2023Inventors: Ling Su, Anqi He, Ritesh Shreevastav, Zhipeng Lin, Robert Mark Harrison

Publication number: 20230092305Abstract: A video encoding system in which pixel data is decomposed into frequency bands prior to encoding. The frequency bands are organized into blocks that are provided to a block-based encoder that encodes the blocks and passes the encoded blocks to a wireless interface that packetizes the blocks for transmittal over a wireless connection. The encoder may categorize the encoded frequency bands into multiple priority levels, and may tag each frequency block with metadata indicating the frequency band represented in the block, the priority of the frequency band, and timing information. The wireless interface may then transmit or drop packets according to the priority levels of the encoded frequency blocks in the packets and/or according to the timing information of the frequency blocks in the packets.Type: ApplicationFiled: November 4, 2022Publication date: March 23, 2023Applicant: Apple Inc.Inventors: Sorin C.
