US 2026/0313616 A1 · RESERVATION CHANNEL TRANSMISSION IN V2V COMMUNICATIONS

Abstract

A network configures (e.g., allocates) reservation channel resources within a reservation channel resource pool. In some cases, the time-frequency resources available to use for reservation channel transmissions are distributed periodically in a time-frequency domain. In other cases, the time-frequency resources available to use for reservation channel transmissions are distributed non-periodically in a time-frequency domain. For example, the time-frequency resources available to use for reservation channel transmissions could be distributed in a pre-determined manner (e.g., deterministically) within the time-frequency domain. Regardless of the type of distribution, the wireless communication devices of a vehicle ad-hoc network (VANET) are made aware of the distribution/location of the reservation channel resources so that the wireless communication devices can attempt to decode the reservation channel transmissions at the appropriate location (e.g., within the time-frequency domain).

Claims19

Dependent claims

A method comprising:

selecting, by a wireless communication device, time-frequency resources to use for a control channel transmission, the time-frequency resources selected from a resource pool;
and
transmitting, from the wireless communication device to at least one other wireless communication device, the control channel transmission using the selected time-frequency resources, the control channel transmission comprising resource location information indicating reserved time-frequency communication resources of a future data transmission that will be transmitted by the wireless communication device.

Dependencies are inferred from the claim text.
