Abstract: 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.

Abstract: 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.
Abstract translation: 提供了一种用于在支持上行链路分组数据业务的移动通信系统中发送和接收下行链路控制信息的方法和装置。 为了在HARQ移动通信系统中传送分组数据，第二收发机从第一收发机接收作为速率控制信息的RG。 如果RG指示保持，则第二收发器将应用RG的HARQ进程的允许最大数据速率设置为HARQ进程之前的HARQ进程的允许的最大数据速率。 第二收发器将设置的允许的最大数据速率内的分组数据发送到第一收发器。

Abstract: A method and apparatus are provided for transmitting power headroom information by a terminal in a mobile communication system. The method includes receiving, by the terminal, information for an allocated uplink transmission resource; identifying whether a path loss has changed by more than a threshold, after transmitting last power headroom information, when the terminal has the allocated uplink transmission resource; in case that the path loss has changed by more than the threshold when the terminal has the allocated uplink transmission resource, determining a transmission of the power headroom information; and transmitting an uplink packet including the power headroom information based on the allocated uplink transmission resource. The power headroom information is obtained based on a difference between a maximum transmission power of the terminal and a transmission power of the terminal.
