摘要： An intelligent assisted transmission method is provided. In the method, a Multicast and Broadcast Service (MCBCS) Server transmits Multicast Broadcast Service (MBS) data to a base station in an MBS area. The base station transmits the MBS data to a user equipment. If the user equipment cannot correctly receive the MBS data, it returns a Not Acknowledgement (NACK) message to the base station. The base station transmits an intelligent assisted transmission prompt to the MCBCS Server. The MCBCS Server transmits an intelligent assisted transmission request to adjacent base stations of the base station. When the intelligent assisted transmission request is received, the adjacent base stations return an intelligent assisted transmission response. The MCBCS Server transmits the MBS data to the adjacent base stations, and the adjacent base stations transmit the MBS data to the user equipment.

摘要： A method for generating/parsing a resource allocation indication message, a transmitter and a receiver are disclosed. In the method of the present invention, each resource unit is mapped to one bit, and information about service types provided by each serving zone is obtained by mapping an added virtual resource unit to one bit or by secondary mapping. Bits to which part of or all of the above resource units are mapped, or bits to which part of or all of the above resource units and the virtual resource unit are mapped, or bits to which part of or all of the above resource units are mapped and bits obtained by the secondary mapping, constitute a resource allocation indication, and the number of serving zones, the start resource unit and end resource unit of each serving zone and the service type of each serving zone can be learned according to the resource allocation indication and a prearrangement between the transmitter and the receiver. In the present invention, the overhead of indication is unrelated to the number of serving zones to be indicated, and obvious advantages can be obtained when the number of serving zones to be indicated changes in a large range and/or the number of serving zones to be indicated is large.

摘要： A method for random access of Machine to Machine (M2M) terminals is applied in a situation involving a plurality of M2M terminals. The method comprises dividing the plurality of M2M terminals into at least one terminal group, and allocating an identifier for each terminal group; and after receiving the paging broadcast signaling transmitted by the base station, a M2M terminal in a terminal group determines whether the terminal group identifier carried in the paging broadcast signaling is the identifier of the terminal group that includes the M2M terminal, if yes, and the M2M terminal starts a random access process. A base station transmits a paging broadcast signaling on the basis of a terminal group rather than issuing a paging broadcast signaling only to individual M2M terminals so that a large amount of M2M terminals can be randomly accessed smoothly and efficiently without causing network access congestion nor affecting the use of public network users.

摘要： A method of and system for time-division-based channel collision collaboration in a wireless communication system including at least two Wireless Regional Area Networks (WRANs) with overlapping service areas that employ dynamic frequency hopping is provided. The method includes performing, by at least one Consumer Premise Equipment (CPE) located in an overlapping portion of service areas of at least two WRANs, spectrum sensing and feeding idle channel information back to respective Base Stations (BSs) of the at least two WRANs, broadcasting, by each of the at least two WRANs, a pre-occupation announcement message for a qualified idle channel, and determining, by a WRAN with the highest priority of the at least two WRANs, a time resource allocation for WRANs in a channel collision state of the at least two WRANs. The method addresses problems, such as a large delay and impaired wireless access due to an absence of an idle channel for adjacent WRANs, may be avoided, while the WRANs may maintain their QoSs. Therefore, transmission power of a WRAN during non-operation period may be conserved.

摘要： A network accessing method includes selecting a group representative dynamically from each machine to machine (M2M) terminal group, wherein terminals in the M2M terminal group not selected as the group representative serve as group members. The method also includes requesting, by the group representative, network access from a base station, and serving, as a group member automatically after entering an idle state or entering another cell. This enables multiple M2M terminals to access a network at the same time while avoiding network access congestion.
