User equipment architecture for inter-device communication in wireless communication systems

摘要

User equipment (UE) architecture for inter-device communication in wireless communication systems is provided. A UE may communicate directly with another UE over a direct inter-device communication link when they are located in proximity. Long term evolution (LTE) downlink or uplink radio resources may be used for communications over the inter-device communication link. The UE may simultaneously maintain an active communication link with its serving base station while communicating with other UEs over the inter-device communication link. To communicate with the base station and other UEs simultaneously, the UE may include additional transmit or receive chain to support the inter-device communications over the inter-device communication link.

主权项

1. A method at a user equipment (UE) for wireless communication, comprising:
transmitting a first signal, corresponding to a first message, to a base station using a first transmit chain; and transmitting a second signal, corresponding to a second message, to one or more other UEs over one or more inter-device communication links using a second transmit chain; receiving a third signal, corresponding to a third message, from the base station; and receiving a fourth signal, corresponding to a fourth message, from the one or more other UEs over the one or more inter-device communication links at substantially the same time as receiving the third signal.
