Sony patents method for phones to extend their time slot in wireless networks
Sony describes a system where a device tells a base station if it needs more time to send data. The base station then sends a signal confirming whether the device can keep using the channel past its original time limit. This helps the device know exactly when to stop transmitting to avoid interfering with others.
In the filing’s own words
A terminal device is time-synchronized with a communication device at a synchronization boundary. The terminal device includes a wireless communication transceiver and a control circuitry. The control circuitry is configured to transmit determination information for determining whether or not to extend a channel occupancy time (COT) via a wireless transceiver, receive information regarding the COT, and perform uplink transmission on the basis of the information regarding the COT that has been received. In a case where the information regarding the COT does not indicate extension of the COT, the COT ends at least by a first sync boundary. In a case where the information regarding the COT indicates extension of the COT, the COT ends after the first sync boundary and by the end of a second sync boundary that occurs following the first sync boundary.
What exactly they claim (claim 1)
1. A terminal device that performs synchronous communications with a base station, the terminal device comprising: a wireless transceiver; and control circuitry, wherein the control circuitry: transmits, to the base station via the wireless transceiver, determination information for determining whether or not to extend a channel occupancy time (COT) that has been previously assigned to the terminal device by the base station; receives information regarding the previously assigned COT from the base station, the information regarding the previously assigned COT being based on the determination information; and performs an uplink transmission to the base station based on the information regarding the previously assigned COT, wherein, in a case where the information regarding the previously assigned COT does not indicate that the previously assigned COT may be extended, the previously assigned COT is not extended so that the uplink transmission ends at least by a first sync boundary corresponding to the previously assigned COT, and in a case where the information regarding the previously assigned COT indicates that the previously assigned COT may be extended, the previously assigned COT is extended so that the uplink transmission ends by a second sync boundary that occurs after the first sync boundary, wherein the determination information includes each of: information regarding a carrier sensing result at a sync boundary prior to the first sync boundary, information regarding a timing at which the previously assigned COT has been acquired, information regarding a timing at which the uplink transmission is to be started, information regarding a maximum COT length, and a channel access priority class (CAPC).
