    摘要: A method and apparatus for transmitting data are provided. In the method, data streams are mapped onto frames, a word is generated including information for receiving the data streams for a given frame, and parity bits are derived from the word for the given frame. The data is arranged in the frames. Each of the frames includes a preamble and a data section. The preamble and the data section are time-multiplexed. The data section includes at least a part of the data streams, and the preamble includes signaling information. The word is inserted in a preamble section of the given frame, and one of the parity bits is inserted in a preamble section of a prior frame preceding the given frame. A part of the word for the given frame is inserted within a data section of an earlier frame preceding the prior frame. The frames are then transmitted.

    摘要: A method for determining if a handover of a half-duplex terminal has to be executed from a first base station to a second base station, the half-duplex terminal not transferring and not receiving signals during a period of time, called an idle period. The first base station transfers to the half-duplex terminal a downlink signal in the cell of the first base station. The first base station receives a message in response to the downlink signal including information relative to quality measurements on the downlink signal transferred by the first and the second base stations. The first base station determines the round trip delay between the half-duplex terminal and the second base station. The first base station further transmits a handover notification message to the half-duplex terminal instructing the half-duplex terminal to execute a handover procedure from the first base station to the second base station.

    摘要: An encoder and a decoder employ an encoding scheme corresponding to a parity check matrix which is derivable from a bipartite protograph formed of variable nodes and check nodes, with each variable node corresponding to a codeword symbol position. The protograph has a plurality of groups of nodes, each group of nodes comprising both variable nodes and check nodes. Each of the check nodes in a group is of degree 2 and has connections to two variable nodes in the same group. The protograph also has a plurality of check nodes of degree n, where n is the number of said plurality of groups, wherein each of the plurality of check nodes has a connection to a variable node in each group such that the symbol positions in a codeword are interleaved between the groups of nodes.
