摘要： An approach provides an error-control scheme within a multi-hop relay network. A determination is made of a first node that failed to transmit a packet generated according to an error- control scheme, wherein the first node is among a plurality of nodes configured to operate in a multi- hop network. Resources of the multi-hop network are reserved only for retransmission of the packet from the first node towards a destination node that is included in the plurality of nodes.

摘要： A prospective relay station sends a report indicative of radio resource sets/preamble sequences used by its neighbors. Where the reported radio resource sets comprise less than all available radio resource sets, a radio resource set that is not indicated in the report is assigned; else where the reported radio resource sets comprise all available radio resource sets, a resource set indicated in the report is assigned. A message is sent to the prospective relay station indicates the assigned radio resource set and an identifier for use as an enabled relay station. The message may include signal strength and IDs. Apparatus, methods and computer programs are detailed for both a base station and the relay node. Radio resource set re-assignment, managed mode relay operations (where the base station schedules traffic among relays using the same radio resource set), and power control of relays and associated mobile stations are also described.

摘要： Various example embodiments are disclosed relating to synchronization of frames using bidirectional transmit and receive zones. An example method includes delaying, at a wireless relay station, a start time of a frame. In the example method, the start time of the frame is delayed, such that the relay station receives one or more data symbols from a superordinate wireless station and one or more data symbols from a subordinate wireless station at substantially the same time during the frame.

摘要： A macro wireless communication system includes a base station and a femto access point for communicating with user equipment (UE), such as handset, whereby the UE receives information regarding the network relationships between the base station and the femto access point. A home profile setting may be stored in the UE. When the UE communicates with a femto access point that is identified in the home profile, the UE adapts a neighbor listing provided by the home femto access point. Alternatively, the base station stores a list of the UE and its corresponding home femto access point, along with the neighbor list of the femto access point. When a UE is connected to the base station and that base station is in neighbor list of the UE's home femto access point, a message is sent to the UE to forward an appropriate neighbor list to simplify handovers.

摘要： A method of adaptive error correction coding includes processing data during a connection between a transmitting entity and a receiving entity, where the data is processed in accordance with a predetermined coding scheme. More particularly, processing data can include encoding one or more sequences received by an error correction encoder of the transmitting entity, or decoding one or more block codes received by an error correction decoder of the receiving entity. During the connection, then, the method can include selecting or receiving a selection of feedback code information. Thus, during at least a portion of the connection, the data processing can be switched to processing data in accordance with a parity-check coding technique based upon the feedback code information.

摘要： A system, transmitter, receiver, method, and computer program product are provided in which a plurality of structured interleavers permute data bits arranged in a data bit matrix for Zigzag encoding. For each interleaver, the data bits in each column of the data bit matrix are cyclically shifted, with the amount of the shift being predefined and different for each column. In addition to the cycle shift, each column may be bit reverse ordered, and entire columns may be swapped. The interleaved data bit matrix may then be encoded using a Zigzag encoder to generate parity bits that may be transmitted, along with the data bits, from a transmitter to a receiver where the data may be iteratively decoded.
