An apparatus and method for designing a relay backhaul channel in a wireless communication system are provided. At least one relay node utilized for communication with respective user devices and at least one relay backhaul channel for conducting in-band half-duplex communication with the at least one relay node are identified. The relay backhaul channel may be an FDM channel, a TDM/FDM channel, or a joint R-PDCCH/R-PDSCH channel. The relay channel is used for communicating with the at least one relay node. The supportable ranks of the R-PDSCH channel may depend on the number of resources reserved for demodulation reference signals in the R-PDCCH region.

摘要:
For range expansion, a determination to enter range expansion may be made based on a signal strength differential for user equipment (UE) communications between a first class of base stations and a second class of base stations. If the signal strength differential is beyond a certain threshold, range expansion may be implemented. In range expansion, a signal is transmitted, on a resource coordinated with at least one of the first class of base stations, from one of the second class of base stations to the UE which could experience dominant interference from one of the first class of base stations if coordination were not performed. Transmission power may be reduced from one of the first class of base stations on that resource. The second signal may be transmitted within the region of the Physical Downlink Shared Channel.

Methods, apparatuses, and computer program products are disclosed for facilitating indicating and detecting control region sizes. A multi-carrier communication between a wireless terminal and a base station is facilitated by a first carrier having a first control region size and a second carrier having a second control region size. Embodiments are disclosed in which control region sizes are ascertained from a control signal, wherein the control is generated by either scrambling an aspect of the control signal based on the second control region size, or relating the second control region size with the first control region size. Other disclosed embodiments for ascertaining control region sizes include a reverse interleaver embodiment, wherein a set of modulation symbols is mapped beginning from a last data symbol and ending with a first available data symbol.

An apparatus and method for communicating information in a relay downlink backhaul between a base station and at least one relay node comprising: determining a first starting symbol index of at least one control channel in the relay downlink backhaul; determining a second starting symbol index of at least one data channel in the relay downlink backhaul; and communicating information using the at least one control channel based on the first starting symbol index and the at least one data channel based on the second starting symbol index in the relay downlink backhaul. In one example, the apparatus and method comprise receiving information using a control channel based on a first starting symbol index and a data channel based on a second starting symbol index in the relay downlink backhaul.
摘要:
Methods, systems, apparatus and computer program products are provided to facilitate the configuration and allocation of control information associated with transmissions of a wireless communication system. In systems that utilize multiple component carriers, cross-carrier signaling may be used to carry the control information associated with one component carrier on a different component carrier. By allowing control information messages to share their allocated search spaces, the number of decoding attempts needed to obtain control information can be kept within desirable limits while improving scheduling and resource allocation flexibility. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the disclosed subject matter. Therefore, it is to be understood that it should not be used to interpret or limit the scope or the meaning of the claims.
