Apple patents 5G signal method for ultra-reliable data delivery
This patent describes a way to send control signals from multiple antenna locations simultaneously to ensure data arrives reliably. It uses specific timing and frequency rules to repeat these signals so they can be received even in difficult network conditions.
In the filing’s own words
Embodiments disclosed herein can enable multi-TRP transmission for PDCCH to achieve diversity gain for the potential benefits to URLLC use cases with challenging reliability/robustness requirements. Specifically, multi-TRP transmission for PDCCH can be performed at different levels as follows: 1. PDCCH with multi-TRP transmission on repetition level; 2. PDCCH with multi-TRP transmission on CCE level; and/or 3. PDCCH with multi-TRP transmission on REGB level.
What exactly they claim (claim 1)
1. An apparatus for enabling multi-Transmission Reception Point (TRP) transmission, the apparatus comprising: processor circuitry configured to: determine a repetition level parameter to indicate a maximum number of repetitions of a plurality of repetitive physical downlink control channel (PDCCH) blind decoding candidates supported by the PDCCH, determine a repetition interval parameter to indicate a number of Orthogonal Frequency Division Multiplexing (OFDM) symbols between adjacent repetitions of PDCCH blind decoding candidates from among the plurality of repetitive PDCCH blind decoding candidates, and determine a repetition domain parameter to indicate whether the plurality of repetitive PDCCH blind decoding candidates are to be repeated by a plurality of transmission reception points (TRPs) in a time domain or a frequency domain, and construct the plurality of repetitive PDCCH blind decoding candidates in accordance with the repetition level parameter, the repetition interval parameter, and the repetition domain parameter; and radio front end circuitry configured to transmit the plurality of repetitive PDCCH blind decoding candidates by the plurality of TRPs over the PDCCH.
