Disclosed are an apparatus and a method for controlling a reverse rate of data transmitted to a BTS (base transceiver station) from MSs (mobile stations), to which an autonomous rate control is granted. The method includes the steps of checking whether a limitation for a reverse autonomous rate of an MS is persistent when it is determined from a reverse load that the limitation for the reverse autonomous rate of the MS is necessary, and transmitting information for limiting the reverse autonomous rate of the MS and information indicating persistence of the limitation for the reverse autonomous rate to the MS when it is necessary to persistently maintain the limitation for the reverse autonomous rate of the MS.

Disclosed is a method for generating a public long code mask (PLCM) so that a mobile station can receive a Broadcast/Multicast Service (BCMCS), in a mobile communication system including a base station and at least one mobile station located in a cell occupied by the base station, the BCMCS being provided from the base station to the mobile station. The PLCM is created by a combining a BCMCS flow identifier (BCMC_FLOW_ID) and a BCMC service reference identifier (BSR_ID) matched thereto from a BCMCS service parameter message (BSPM) including information related to the BCMC_FLOW_IDs indicating individual flow IDs for identifying flows from respective broadcasting stations and BSR_IDs matched to the BCMC_FLOW_IDs, the BSPM being transmitted from the base station to the mobile station over at least one channel.

A channel assigning device and method in a CDMA communication system is described. According to one aspect of the present invention, in a channel assigning method for a base station, the base station establishes a first dedicated channel and communicates with a mobile station on the established dedicated channel. Then, the base station determines the type of a second dedicated channel and channel spreading code information upon request for additional assignment of a second dedicated channel while in the conversation state, assigns the second dedicated channel, and generates a channel assignment message including the determined channel assignment mode and channel spreading code information to assign the second dedicated control channel. The base station transmits the channel assignment message to the mobile station on the first dedicated channel.

A common channel communication method for a base station in a mobile communication system including common channels, each of which support at least two data rates. The method comprises determining a data rate of the common channel available in a common channel service state and a frame length serviceable at the determined data rate, transmitting a message including information about the determined data rate and frame length on a specific forward common channel before transmission; and upon receipt of an acknowledge message through a specific reverse common channel, setting a data rata and a frame length of the common channel to the determined values.

An information frame of a new format transmitted according to a radio link protocol (RLP), and a device and method for transmitting and receiving the information frame in a mobile communication system. The information frame is comprised of a plurality of consecutive multiplex frames each having a given length. The multiplex frames each are comprised of a header and a succeeding RLP frame, and the RLP frame includes transmission data. At least one of the multiplex frames is comprised of a plurality of sub-multiplex frames, and each sub-multiplex frame is comprised of a header including an RLP service identifier field and a length indication field for indicating a length of the transmission data, and a data block associated to the succeeding RLP frame.

A handoff method in a CDMA communication system using Walsh codes and quasi-orthogonal codes. To implement a handoff, a new base station to which a call is switched notifies a serving base station of an available quasi-orthogonal code, if the new base station has no available Walsh codes. The serving base station transmits a handoff direction message to a mobile station and the mobile station communicate with the new base station using the quasi-orthogonal code included in the handoff direction message.
摘要:
A method, apparatus, and system for negotiating a session between an access terminal (AT) and an access network (AN) that can simplify a repeated negotiation procedure when the session is configured/updated/deleted between the AT and the AN. The AN performs protocol-by-protocol negotiations with the AT for a session configuration. The AN sends, to the AT, a soft configuration complete message including a continue bit indicating if another session configuration is added. The AN and the AT store a negotiated session configuration mapped to a personality index indicated in the message. When all session configurations have been completed, the AN and the AT determine if a session configuration currently in use has been changed. If the session configuration in use has not been changed, the AT and the AN maintain a physical channel. Moreover, the AN sends information indicating if a specific session configuration is applied after session configuration negotiation is completed.

A method for receiving resources allocated from a base station by a terminal in an OFDMA mobile communication system. The method includes receiving, for a data channel, a number of first components, which indicates an amount of resources used with a first resource allocation scheme, and a number of second components, which indicates an amount of resources used with a second resource allocation scheme, from the base station over a common control channel; determining first and second identifier lengths of channel elements for the first and second resource allocation schemes according to the number of first components and the number of second components; receiving resource allocation information including an identifier indicating at least one channel element allocated to the terminal, over a data control channel using one of the identifier lengths; and transmitting and receiving data over a resource of a channel element indicated by the received identifier.
摘要:
A method for providing two or more broadcast services in an orthogonal frequency division multiple access (OFDMA) wireless communication system. The method comprises the steps of separately receiving broadcast services to be transmitted, and independently performing coding, interleaving and modulation on the broadcast services according to a required quality for each of the broadcast services; segmenting each of the modulated broadcast signals into minimum transmission units; time-division-multiplexing the segmented broadcast service signals; configuring a frame comprising information on the broadcast service in physical layer transmission information transmitted together with the broadcast service; and transmitting the frame.
摘要:
A reverse data rate determining method in a mobile communication system for high data rate transmission such as an HDR system, wherein an AN (Access Network) within a cell calculates a total load of a reverse link by measuring a total energy of a reverse link from ATs (Access Terminals) within the cell. The AN calculates the share of each AT in the total reverse link load. If the load share of an AT is greater than a threshold predetermined individually for the AT, the AN determines that the AT should reduce its data rate.
