  • Publication number: 20120188937
    Abstract: The present invention discloses a method on a Long Term Evolution-Advanced (LTE-A) system backhaul link for demodulation pilot transmission, wherein the method includes that: among the resource areas occupied by a Relay-Physical Downlink Shared Channel (R-PDSCH) on the backhaul link, a base station selects the resource units which are preconfigured for sending the demodulation pilot signal of the R-PDSCH; the base station sends the demodulation pilot signal to a Relay Node (RN) belonging to the base station by using the selected resource units. The present invention also discloses a channel demodulation method on the LTE-A system backhaul link, an LTE-A communication system and device. The demodulation performance of the R-PDSCH in the LTE-A system can be ensured with the present invention.

  • Publication number: 20120182931
    Abstract: A configuration method, detection method and equipment for control channels of a relay system are provided in the present invention. The configuration method comprises: the network side transmits a Relay-Physical Downlink Control Channel (R-PDCCH) of a control channel to its service relay equipment, the related control information of said relay equipment is included in said R-PDCCH, said R-PDCCH is a dedicated R-PDCCH of said relay equipment. In the present invention, the dedicated control channel of the relay system is configured according to the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied by a R-PDCCH, and the mapping from a R-PDDCH/Relay-Physical Downlink Shared Channel (R-PDSCH) to a Resource Element (RE), and the demand that one relay node dedicates a R-PDCCH is satisfied.

  • Publication number: 20120069778
    Abstract: The present invention provides a method, device and system for backhaul link communication in a TDD system. Wherein, the method includes: a base station allocating an uplink subframe for uplink transmitting of the backhaul link and a downlink subframe for downlink transmitting of the backhaul link, and notifying subframe allocating information to a relay node; and the base station communicating with the relay node by the uplink subframe and the to downlink subframe of the backhaul link. The solution allocates the uplink subframe and the downlink subframe of the backhaul link according to certain rules, performs related HARQ operation based on the allocated uplink subframe and downlink subframe, and ensures the availability and reliability of backhaul link communication.

  • Publication number: 20120044852
    Abstract: The present invention discloses a resource scheduling method and system, a BS and a RN, which include that: the BS allocates an uplink subframe for performing uplink transmission of a backhaul link and a downlink subframe for performing downlink transmission of the backhaul link, and informs the RN of the allocation information of the uplink subframe and the downlink subframe of the backhaul link, or the BS only informs the RN of the allocation information of the uplink subframe or the downlink subframe of the backhaul link; the RN may determine, according to the received allocation information and a predefined timing relationship, an uplink subframe and a downlink subframe of the backhaul link of which the BS does not inform. By the solution of the present invention, an MBSFN subframe can be indicated to the RN, and uplink transmission conflict can be avoided.
