Embodiment Construction

[0020] The present invention is described in detail below with reference to the accompanying drawings. In the text, the same numbers are used to denote the same components.

[0021] Figure 1A is a simplified block diagram of a Universal Mobile Telecommunications System Terrestrial Radio Access Network (UTRAN) base station 12 (hereinafter referred to as a base station BS 12), which communicates wirelessly via a radio frequency link 25 with a user equipment (UE) 30 (e.g. Figure 1B shown). This user equipment (UE) 30 may be a wireless mobile phone, a personal digital assistant (PDA), or other similar device that may include additional capabilities such as paging, e-mail, or the like.

[0022] The base station BS 12 includes: an antenna 24 (or a plurality of antennas), an isolator / switch 22 (or similar device), a time slot interference measurement device 26, an uplink common control channel receiver 28, a common control channel quality monitoring device 18 , summing device 20, ...

Abstract

Using wireless digital code-division multiple access (CDMA) technology, a method and system in which adaptive modulation and coding (AM & C) is utilized in order to achieve improved radio resource utilization and provide increased data rates for user services in which the base station (12) measures up link interference on all time slots received from user equipment UEs (30) and determines the need for uplink control channel. The base station transmits to the UE the allocation of specific uplink control channels indicating uplink interference in the time slot and potentially the quality margin. The UE (30) determines appropriate uplink power level based on a path loss determination (42) made by the UE, uplink interference and an optional quality margin. The UE (30) then initiates an uplink communication responsive to these determinations.

Description

[0001] This application is a divisional application of a Chinese patent application with the filing date of May 14, 2002, the application number of 02809875.7, and the title of "Method for Calculating the Power Level of Uplink Transmission Power and User Equipment". technical field [0002] The present invention relates to a wireless digital communication system. In particular, the present invention relates to a code division multiple access (CDMA) communication system with uplink power control using adaptive modulation and coding. Background technique [0003] Access to Code Division Multiple Access (CDMA) third generation (3G) mobile telecommunication systems is Adaptive Modulation and Coding (AM&C) for transmission applications to achieve and improve radio resource utilization and provide increased data rates for user Serve. Adaptive Modulation and Coding (AM&C) technology considers radio frequency (RF) propagation conditions before transmission to determine the most fav...
