Patent ID: 8913572

Claim:
A radio self-backhaul method, comprising: a radio self-backhaul device, wherein the radio self-backhaul device is communicatively coupled to (i) a core network through a cable transmission link and (ii) a NodeB through a radio link, wherein the radio self-backhaul device is a first user equipment (UE) for the NodeB, and the radio self-backhaul device performs: accessing the NodeB by using access resources which are the same as or different from access resources used by a second UE, wherein when the access resources used by the radio self-backhaul device are the same as the access resources used by the second UE, a channel associated identifier of the radio self-backhaul device is sent to the NodeB so that the NodeB distinguishes the radio self-backhaul device and the second UE according to the channel associated identifier, wherein when the access resources used by the radio self-backhaul device are different from the access resources used by the second UE, a channel associated identifier of the radio self-backhaul device is not sent to the NodeB so that the NodeB distinguishes the radio self-backhaul device and the second UE according to the different access resources; receiving user uplink data that is sent by the NodeB using downlink radio resources of the NodeB and without occupying radio resources of other NodeBs, wherein the user uplink data is uplink data sent by the second UE to the NodeB using an uplink radio link; protocol processing on the received user uplink data; and sending the received user uplink data that are protocol processed in the radio self-backhaul device to the core network using the cable transmission link.
