TIME HOPPING IN DEVICE-TO-DEVICE TRANSMISSIONS

摘要

Apparatuses, systems, and devices are described for transmissions and retransmissions of device-to-device (D2D) communications. A D2D message may be transmitted during an initial communications period, followed by one or more retransmissions. A device may transmit an initial transmission, determine a time hopping pattern for the retransmission(s), and determine a transmission resource for the retransmission(s) based at least in part on a resource of the initial transmission and the time hopping pattern. The messages may include, for example, a scheduling assignment (SA) for data transmission, or data transmissions from a transmitting device. Time hopping patterns may be determined based on times and/or frequencies of the initial transmission. A base station may transmit a message to a transmitting device that indicates one or more time hopping patterns that are to be used for the transmissions.

1. A method of wireless communications, comprising:
transmitting a message to one or more devices using a first transmission resource; determining a time hopping pattern for retransmission of the message; determining at least a second transmission resource based at least in part on the first transmission resource and the time hopping pattern; and retransmitting the message using the second transmission resource.
