The disclosure provides an anchor authenticator relocation method and system. The method includes: after an old authenticator accepts an anchor authenticator relocation request of a Mobile Station (MS), a new authenticator sends an authenticator relocation request to an AAA server; when the AAA server's verification on the new authenticator is passed and the old authenticator confirms that the new authenticator is trusted, the anchor authenticator is relocated to the new authenticator. The disclosure provides a detailed solution to perform anchor authenticator relocation without re-authentication.

A method for sub-channelization and resource mapping of wireless resources is provided. The method includes: according to bandwidth features or scheduling features supported by a wireless communication system, determining processes of sub-channelization and resource mapping of wireless resources or parameters of the processes. Therefore, the processes of sub-channelization and resource mapping of wireless resources or the parameters of the processes are different when the bandwidth features or scheduling features are different.

A control information transmission method and a control information receiving terminal are provided. The transmission method comprises: notifying a terminal of setting information of control information in a downlink subframe (S202); and transmitting the control information to the terminal in a preset subframe and other subframes determined according to the setting information (S204). By transmitting the control information on part of the 16m subframes and notifying the 16m terminal of the information of setting the control information, the present invention enables the 16m terminal to shut down the RF transmission at the location of a subframe where the control information is not included and no resource related to the terminal is assigned, and to enter the micro sleep mode, which reduces power consumption of the terminal.

The invention discloses a hybrid automatic repeat request method of a downlink tunnel connection in a multi-hop relay system. The base station transmits tunnel data, comprising of protocol data, to the access relay station via the tunnel link, and receives feedback until the access relay station receives the data correctly. The access relay station analyzes the protocol data unit of each mobile station, transmits the protocol data to the corresponding mobile station, and performs the corresponding process after receiving the feedback from each mobile station. Each hop relay station, except for the station accessing the mobile station, will not transmit the reception acknowledgment information to the base station immediately. The corresponding processing after the access relay station receives the feedback is transmitting the feedback from the mobile station to the base station or, not transmitting the feedback, but applying for bandwidth for retransmission according to the feedback of the mobile station.
摘要:
A method, system, and wireless frame structure for supporting different modes of multiple radio access. The described system comprises base stations and terminals. There is a group of base stations at the same location, which include at least two synchronized base stations on the same frequency band, supporting different multiple access techniques in downlink or uplink. The base stations in the described group transmit downlink frames in a negotiated downlink zone and receive uplink frames in a negotiated uplink zone respectively, and the zones of the base stations are not overlapped. Each terminal accesses to one of the base stations according to the downlink multiple access technique that it supports, and receives/transmits signals in the downlink zone/uplink zone allocated to the base station.

A method for mapping resource units is disclosed. The method includes: dividing the physical resource unit set to obtain a first physical resource unit set which is in a unit of N1 continuous physical resource units, and a second physical resource unit set into which the remaining physical resource units are put; permuting, in a unit of N2 continuous physical resource units, the physical resource units in the second physical resource unit set; allocating, in a unit of N1 continuous physical resource units, the physical resource units in the first physical resource unit set to each frequency partition, and allocating, in a unit of one physical resource unit, the permuted physical resource units in the second physical resource unit set to each frequency partition. By using the invention, the combination of external mapping under the two-level sub-carrier mapping manner in the partial frequency multiplexing with the localized mapping and the distributed mapping can be realized.
