Apple patents method for packing data into high-speed wireless uploads

Apple describes a way for phones to send two separate streams of data at once using multiple antennas. The filing details how to fit essential status updates, or control information, into these data streams without causing errors.

Why it mattersThis improves the efficiency of how devices talk to cell towers, potentially allowing for faster and more reliable mobile connections.

In the filing’s own words

Systems and methods using uplink control information multiplexing enhancements for up to eight antenna port transmit (Tx) uplink operations are discussed. A wireless communication system supports the use of two codewords in a single physical uplink shared channel (PUSCH) sent by a user equipment (UE) to a network, where the PUSCH is sent with a rank that is greater than four (e.g., using more than four layers). Herein, various examples are provided with respect to manners of encoding uplink control information (UCI) to be multiplexed into one or more of the two codewords, manners of using beta offsets for UCI multiplexing into one or more of the two codewords, manners of using scaling factors for UCI multiplexing with one or more of the two codewords, and/or manners of identifying a single one of the codewords for UCI multiplexing use/extraction. Different treatments based on UCI types within these contexts are discussed.

What exactly they claim (claim 1)

1. A method of a user equipment (UE), comprising: generating a pair of codewords for a physical uplink shared channel (PUSCH); identifying a first codeword of the pair of codewords into which to multiplex uplink control information (UCI); multiplexing the UCI into the first codeword; and transmitting, to a network, the PUSCH comprising the pair of codewords.
