Abstract
Embodiments of the present invention relate to a radio self-backhaul method, device, and system in an evolved network. With the radio self-backhaul method, device, and system provided in the embodiments of the present invention, the NodeB sends the uplink data to the core network by using the cable transmission link without occupying the radio resources of other NodeBs. This implements the radio self-backhaul for the NodeB, saves the radio transmission resources of the NodeB, and mitigates the impact on the radio network throughput.
Claims17
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.
A radio self-backhaul device, 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 comprises a processing hardware platform executing instructions stored on a non-transitory computer-readable storage medium, the instructions are executed which cause the radio self-backhaul device to:
- access 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;
- receive 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 process on the received user uplink data;
- and
- send the received user uplink data that are protocol processed in the radio self-backhaul device to the core network using the cable transmission link.
A radio self-backhaul system, comprising:
- a radio self-backhaul device, a second user equipment (UE), and a NodeB, wherein the radio self-backhaul device is a first UE for the NodeB and is communicatively coupled to (i) a core network through a cable transmission link and (ii) the NodeB through a radio link, and the radio self-backhaul device comprises a processing hardware platform executing instructions stored on a non-transitory computer-readable medium, the instructions are executed which cause the radio self-backhaul device to:
- access the NodeB by using access resources which are the same as or different from access resources used by the 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;
- receive 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 process on the received user uplink data;
- and
- send the received user uplink data that are protocol processed in the radio self-backhaul device to the core network using the cable transmission link.
