Sony patents method for 5G devices to share time with network signals

Sony describes a way for wireless devices to send data while the network is broadcasting synchronization signals. The system splits the communication time into small units, allowing the device to transmit in the gaps where the network is not using the channel.

Why it mattersThis improves how efficiently 5G networks handle simultaneous sending and receiving, which could lead to faster and more reliable connections for users.

In the filing’s own words

A method of operating a communications device includes sending an uplink transmission via a wireless access interface having OFDM slots. At least one slot includes Subband Full Duplex (SBFD) OFDM symbols, each with multiple downlink resource units (RUs) and multiple uplink RUs. Infrastructure equipment transmits a synchronization signal block (SSB) in downlink RUs of one or more SBFD symbols. The device determines that a subset of uplink RUs within the SBFD symbol(s) used for the SSB are disabled for uplink, and transmits at least part of the uplink in other uplink RUs of the same SBFD symbol(s).

What exactly they claim (claim 1)

1. A method of operating a half-duplex, HD, communications device, the method comprising transmitting an uplink transmission to infrastructure equipment of a wireless communications network via a wireless access interface, the wireless access interface comprising one or more Orthogonal Frequency Division Multiplexing, OFDM, slots, one or more of the OFDM slots comprising one or more Subband Full Duplex, SBFD, OFDM symbols, each of the one or more SBFD OFDM symbols comprising a plurality of downlink resource units and a plurality of uplink resource units, wherein one or more of the SBFD OFDM symbols are used by the infrastructure equipment for transmitting a synchronisation signal block, SSB, the SSB being transmitted by the infrastructure equipment in a plurality of the downlink resource units in the one or more SBFD OFDM symbols used for transmitting the SSB and the transmitting of the uplink transmission comprises determining that a subset of the uplink resource units in the one or more SBFD OFDM symbols used by the infrastructure equipment for transmitting the SSB are disabled for uplink transmissions, and transmitting at least a part of the uplink transmission in a plurality of the other uplink resource units in the one or more SBFD OFDM symbols used by the infrastructure equipment for transmitting the SSB.
