Apple patents method for selecting wireless signal reference points

Patent drawing
Patent drawing from the official filing.

This filing describes a way for a device to choose specific reference signals, known as DMRS ports, when sending data to a network. The device uses tables provided by the network to pick the right signal configuration, which can include standard or enhanced port options.

Why it mattersIt is a routine technical update to how mobile devices manage their wireless connections, likely improving data reliability without changing the user experience.

In the filing’s own words

An apparatus comprising configured to process, based on signals received from a network, a plurality of tables, wherein each table comprises one or more entries related to a selection of demodulation reference signal (DMRS) ports for a Physical Uplink Shared Channel (PUSCH), process, based on signals received from the network, a DMRS type 2 configuration for the PUSCH, select an entry from one of the plurality of tables based on the DMRS configuration and generate, for transmission, the PUSCH comprising DMRS type 2 on the DMRS ports corresponding to the entry, wherein the DMRS ports are at least one of (i) legacy ports or (ii) enhanced ports.

What exactly they claim (claim 1)

1. An apparatus comprising processing circuitry configured to: process, based on signals received from a network, a plurality of tables, wherein each table comprises one or more entries related to a selection of demodulation reference signal (DMRS) ports for a Physical Uplink Shared Channel (PUSCH); process, based on signals received from the network, a DMRS type 2 configuration for the PUSCH; select an entry from one of the plurality of tables based on the DMRS configuration; and generate, for transmission, the PUSCH comprising DMRS type 2 on the DMRS ports corresponding to the entry, wherein the DMRS ports are at least one of (i) legacy ports or (ii) enhanced ports.
