摘要： Provided is a network re-entry method and apparatus in a mobile communication system. The network re-entry method includes sending, by a group delegate Mobile Station (MS) among MSs of a group, a ranging code based on a group Identifier (ID) to a Base Station (BS) and receiving, by the MSs, a Ranging-Response (RNG-RSP) message comprising a ranging status for the group from the BS.

摘要： A network access method and an apparatus are provided. The Machine to Machine (M2M) terminal in one M2M terminal group determines an access resource according to an identifier of the M2M terminal group which the M2M terminal is a member of, and The M2M terminal of the M2M terminal group uses the determined access resource to conduct network access on behalf of the M2M terminal group. The method and apparatus can ensure that numerous M2M terminals can successfully access the network at the same time.

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.

摘要： A system for transmitting and receiving channel state information (CSI) is provided, in which a terminal receives a pilot signal transmitted from a transmitter; the terminal estimates CSI of part of downlink channels based on the received pilot signal; the terminal superposes the CSI of part of downlink channels onto a uplink sounding signal orthogonally, and transmits them together; the transmitter obtains the CSI of the rest part of downlink channels by estimating the uplink sounding signal; the transmitter performs orthogonal de-multiplexing on the received signal to obtain the CSI of the part of downlink channels; the transmitter, by using the CSI of the two parts of downlink channels, pre-codes downlink data and transmits it to the terminal. With the system of the present invention, it is possible to solve the problem that the transmitter can not obtain complete CSI due to the fact that uplink and downlink antenna configurations are not matched with each other. Accordingly, it is possible to improve system performance and reduce the complexity of the receiver. Meanwhile, system overhead can be suppressed.
