Abstract

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Dependent claims

A method comprising:

determining, by a first device, a time window that includes a plurality of time slots that can be used to determine a time slot for communication with another device using a single-slot resource on a sidelink communication channel;
determining, by the first device, a first offset and a second offset that identify the time window with respect to a reference time slot;
and
sending, during the reference time slot and by the first device, a message i) to a second device and that ii) identifies the first offset and the second offset that identify the time window and iii) includes a request for the second device to respond with an identification of one or more time slots in the time window for the single-slot resource.

1 more element

A non-transitory computer storage medium encoded with instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

determining a time window that includes a plurality of time slots that can be used to determine a time slot for communication with another device using a single-slot resource on a sidelink communication channel;
determining a first offset and a second offset that identify the time window with respect to a reference time slot;
and
sending, during the reference time slot, a message i) to a second device and that ii) identifies the first offset and the second offset that identify the time window and iii) includes a request for the second device to respond with an identification of one or more time slots in the time window for the single-slot resource.
