Architecture for relays in LTE using D2D

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives downlink data from a base station via a downlink resource, sends the downlink data to a user equipment (UE) via an uplink resource, receives uplink data from the UE via the uplink resource, and sends the uplink data to the base station via the uplink resource. The apparatus also determines at least one of an observed downlink signal-to-interference-plus-noise ratio (SINR) or an observed uplink interference. The apparatus then broadcasts a relay availability based on the determination that the at least one of the downlink SINR observed is greater than a first threshold or the uplink interference at the relay is less than a second threshold.

主权项

1. A method of wireless communication, comprising:
receiving, at a relay, downlink data from a base station via a downlink resource; sending the downlink data from the relay to a user equipment (UE) via an uplink resource; determining, at the relay, at least an uplink interference; and broadcasting, at the relay, a relay availability based on the determined uplink interference being less than a threshold, to facilitate determination of an access link uplink rate based on the determined uplink interference and a pathloss between the relay and the UE, wherein a selection of the relay for communication is based on at least the access link uplink rate or an access link downlink rate based on the pathloss and an uplink interference observed by the UE.
