  • Publication number: 20100284298
    Abstract: A method for transmitting information by using Cyclic Prefix (CP) timeslots includes a transmitter transmitting CP information at a portion of CP timeslots when transmitting the timeslots or transmitting no CP information at CP timeslots when transmitting the CP timeslots. A method for using CP timeslots effectively and an apparatus for using CP timeslots are also disclosed.

  • Publication number: 20100261476
    Abstract: A method for transferring information of a neighboring cell in a wireless communications system includes locating position information of user equipment (UE) when detecting that the UE is in a service connection state, and if determining that the UE is in a coverage threshold range of a micro-cell adjacent to a current macro-cell according to the position information of the UE, transferring information of the micro-cell to the UE. Corresponding network equipment is also provided.

  • Publication number: 20100110972
    Abstract: An apparatus and a method for processing the relayed data in a multihop relay broadband wireless access communication system are provided. A method for an operation of a Relay Station (RS) includes determining whether a packet received from an upper node comprises a Relay Media Access Control (MAC) Header (RMH), when the RMH is comprised in the received packet, determining whether the RMH comprises access RS information, and when the access RS information is not comprised in the RMH, removing the RMH from the received packet and transmitting the packet to a lower Mobile Station (MS).

  • Publication number: 20090296622
    Abstract: A method for allocating frequency resources by a Base Station (BS) in a frequency overlay system is provided. The method includes grouping at least one Mobile Station (MS) capable of using the same Frequency Allocation (FA), according to zones, multicasting zone information indicating a frequency resource available for each zone to at least one MS belonging to a corresponding zone, unicasting resource allocation information indicating an allocated frequency resource to at least one MS to which the frequency resource is allocated, among the grouped MSs, and communicating with the at least one MS using the allocated frequency resource indicated by the resource allocation information, within the frequency resource indicated by the zone information.

  • Publication number: 20090258663
    Abstract: A method for paging access terminals. The method includes: a network entity sends a paging message to a target AN. The paging message carries the information required for calculating the time when the AT wakes to monitor the paging message. The information includes the absolute time that is determined according to the time when the AT previously shifts from the connected state to the idle state. Upon receipt of the paging message, the target AN determines when to send the paging message to the AT according to the information carried in the paging message. The present embodiments also disclose a system and apparatus for paging access terminals. The apparatus is a network entity that sends the paging message. The method, system and apparatus can be used to determine the time when the AT wakes to monitor the paging message, thus ensuring that the AT paging is not missed.

  • Publication number: 20090093262
    Abstract: A system and method for terminal access includes transmitting a paging message from a network to a terminal; determining, by the terminal, orthogonal code information which differs from the one being used for current system access according to a predetermined rule; acquiring by the terminal a corresponding orthogonal code according to the orthogonal code information and modulating an access probe according to the orthogonal code; and transmitting the access probe by the terminal to the network and performing network access. In the various embodiments, the terminal responding to the paging selects a unique access orthogonal code according to the method and system. According to various embodiments, conflicts are minimized as a result of using the same orthogonal code between the terminals responding to the paging and between the terminal responding to the paging and the terminal originating the call. Accordingly, latency in the response to paging may be reduced.
