摘要:
A method in a UE of transmitting buffer state information and CSI for scheduling an uplink packet data service in a mobile communication system supporting the uplink packet data service is provided. The buffer state information indicates a state of a data buffer for storing packet data to be transmitted from the UE and the CSI indicates an uplink transmit power of the UE. The UE acquires different transmission intervals of the buffer state information and the CSI, initially transmits the buffer state information and the CSI, if the amount of packet data stored in the buffer is equal to or greater than a predetermined threshold, and periodically transmits the buffer state information and the CSI at the transmission intervals.

Disclosed is a method and an apparatus for multiplexing and transmitting data and uplink control information, and receiving the data and control information in a wireless communication system. In the system multiplexing an uplink packet data channel and a control channel, a transport format of the control channel for transmission of the control information is changed according to the transport format of the data channel. The disclosed method and apparatus can control the quantity of resources for the control channel in the case of transmitting high speed data, and thus can the efficiency of the data channel resources.

A method for configuring gain factors in a WCDMA telecommunication system is provided in which the gain factor for defining power required for normal reception of uplink data in an environment supporting an uplink service over an E-DCH can be configured using minimal signaling information. First gain factors for first TFs corresponding to a part of a TF set including a plurality of TFs available for an uplink service are received. One of the first TFs is determined as a reference TF for a second TF other than the first TFs in the TF set. Then, a second gain factor for the second TF is calculated using the first gain factor for the determined reference TF. The second gain factor is used for transmitting or receiving uplink data.

A method and apparatus for transmitting and receiving downlink control information in a mobile communication system supporting an uplink packet data service are provided. To transmit packet data in an HARQ mobile communication system, a second transceiver receives an RG as rate control information from a first transceiver. The second transceiver sets the allowed maximum data rate of an HARQ process to which the RG is applied to the allowed maximum data rate of an HARQ process previous to the HARQ process, if the RG indicates hold. The second transceiver transmits packet data within the set allowed maximum data rate to the first transceiver.
摘要:
An apparatus and method for allocating resources in an Single Carrier-Frequency Division Multiple Access (SC-FDMA) communication system are provided, in which a Node B performs inter-subband hopping on a resource unit for a User Equipment (UE) on a frequency axis along which at least two subbands are defined, at each predetermined hopping time, determines whether to turn on or off mirroring in a subband having the hopped resource unit on a cell basis at the each hopping time, selects a resource unit by selectively mirroring the hopped unit according to the determination, and allocates the selected resource unit to the UE.

摘要:
A method and apparatus for controlling an uplink data rate, without increasing downlink signaling overhead, in a mobile communication system that supports an uplink packet data service. A Node B transmits an Absolute grants (AG) using one of first and second IDs to a User Equipment (UE). Upon receipt of an AG with the first UE-ID, the UE transmits uplink data within an allowed maximum data rate indicated by the AG and receives a Relative Rrant (RG) in the next Transmission Time Interval (TTI). Upon receipt of an AG with the second UE-ID, the UE does not receive an RG.
