    Abstract: The present invention discloses a transmission method and system for a Relay Physical Downlink Control Channel (R-PDCCH). The method comprises the steps of: an eNB bearing downlink grant information of a relay node onto an available Orthogonal Frequency Division Multiplex (OFDM) symbol of a first slot of a pre-allocated Physical Resource Block (PRB) pair used for bearing the R-PDCCH, wherein available OFDM symbols in the PRB pair, other than the OFDM symbol used for the downlink grant information, are used for bearing a Physical Downlink Shared Channel (PDSCH) of each relay node (S602′); the eNB transmitting the PRB pair bearing the downlink grant information and the PDSCH to the relay node (S604′). The present invention is well applicable to a link between an eNB and a relay node, and meanwhile enables backhaul resources to be used adequately.

    Abstract: A machine-type communications (MTC) device may attempt a network attach operation corresponding to a wireless network, and receive quality of service information, from the wireless network, in response to the network attach operation failing. The MTC device may determine a back-off time based on the quality of service information received from the wireless network. The back-off time may include a duration of time before re-attempting the network attach operation. The MTC device may re-attempt the network attach operation in response to detecting an expiration of the back-off time.

    Abstract: The present disclosure provides a mapping and resource allocation method for R-PDSCH, including: when resources allocated for an R-PDCCH overlap with resources allocated for the R-PDSCH, data of the R-PDSCH is not mapped or sent on over-lapped resources, or the data of the R-PDSCH to be sent on the over-lapped resources is punctured; the data of the R-PDSCH is mapped and sent on all or partial resources which are not occupied by the R-PDCCH; a receiving end receives data according to the mapping method for the R-PDSCH; wherein a resource allocation mode corresponding to a shared channel in an LTE system is reused or a grouping-tree resource allocation mode is used to allocate resources for the R-PDSCH. The present disclosure is well applicable to a link between an eNode-B and a relay node, and the resource allocation mode is flexible, the signalling overhead is lowered, therefore, not only the backward compatibility is ensured, but also the problem of mapping and resource allocation of the R-PDSCH is solved.

    Abstract: Disclosed is a method for a femtocell to reduce interference with an overlapping macrocell. The femtocell determines soft-frequency-reuse (“SFR”) information of the macrocell. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. (Cell-edge users are given a higher transmission power profile in order to overcome potential interference with neighboring macrocells.) Then, the femtocell selects from the cell-center user frequency sub-channels for transmission to the femtocell's users. By transmitting on the cell-center user frequency sub-channels, the femtocell reduces interference with the overlapping macrocell. The femtocell continues to update its knowledge of the macrocell's SFR information and re-assigns frequency sub-channels as the SFR changes. If the macrocell detects that one of its cell-center users is “close enough” to the femtocell, then the macrocell re-assigns the cell-center user as a cell-edge user to overcome interference.
