摘要:
A method and apparatus using Virtual Circuit Switching (VCS) in a new scheme are provided for allocating and employing resources by combining Circuit Switching (CS) and Packet Switching (PS), in which a base station allocates resources of a dedicated channel using the CS to a user and then transmits data on the dedicated channel. When data is not transmitted to the user, the base station allocates the allocated dedicated channel resources for resources of a shared channel and transmits data of a different user. Therefore, system capacity can be increased and a waste of communication resources can be minimized in a wireless communication system for frequently transmitting a small amount of traffic that is sensitive to a delay time.

An apparatus and a method for selectively scheduling channels in mobile communication systems adopting Orthogonal Frequency Division Multiple Access, are provided. In an exemplary apparatus and method, the channels are scheduled with a pilot for measuring the signal-to-noise ratio in order to support the selective schedule of the channels in a reverse direction. At a base station in the mobile communication systems, the method includes requiring a terminal to transmit a pilot, receiving the pilot from the terminal within a specified frequency band or over the whole frequency band, and selectively scheduling channels, requiring the terminal to transmit data having a result of the scheduling therewith and receiving from the terminal the data having the result of the scheduling therewith.
摘要:
A method and apparatus for transmitting a broadcast physical layer packet in a mobile communication system supporting multi-slot transmission and hybrid Automatic Repeat Request (H-ARQ) are provided. The method comprises initially transmitting the broadcast physical layer packet according to a fixed transmission format for at least one first slot interval and retransmitting the broadcast physical layer packet for at least one second slot interval using a variable transmission format different from the transmission format used in the first slot interval.

The invention provides a method for receiving broadcast service data using an Orthogonal Frequency Division Multiplex (OFDM) scheme, the method comprising the steps of: receiving a frame, the frame including broadcast packet of a current transmission of a broadcast service and physical layer transmission information comprising an identifier for identifying the broadcast packet and information indicating a data region where the broadcast packet is located in the frame, wherein the frame further including information for indicating interval associated with a next transmission of the broadcast service relative to the current transmission.
摘要:
A method for supporting frequency hopping of a transmission apparatus by a reception apparatus in a wireless communication system supporting Hybrid Automatic Repeat reQuest (HARQ). The method includes determining whether a particular transmission apparatus has a need to perform hopping of allocating a different logical channel every Transmission Time Interval (TTI); and when there is no need to perform hopping every TTI, sending to the transmission apparatus a command to perform hopping every multiple TTIs, and simultaneously signaling information on a number of the multiple TTIs.
摘要:
A method for resource allocation in an FDMA communication system is disclosed in which the resource allocation method includes distinguishing a dynamic resource allocation service, an amount of resource allocation for which changes every transmission time, and a static resource allocation service, an amount of resource allocation for which is fixed every transmission time; determining a start point of the static resource allocation service in a one-dimensionally arranged logical resource, and sequentially allocating resources for each static resource allocation service; and allocating resources left after the static resource allocation, to the dynamic resource allocation service in a reverse direction as that of the static resource allocation service, starting from a last resource located in the opposite side of static resources for the static resource allocation service in the one-dimensionally arranged logical resource.
