Problems solved by technology

[0006] The existing discontinuous reception technology still has some defects. For example, even if DRX parameters are configured, it may still need to continuously monitor the HS-SCCH, and related timers need to be started and stopped continuously, so that the user equipment UE cannot recognize An appropriate time to go to sleep affects the UE standby power consumption in enhanced CELL_FACH state

Embodiment Construction

[0039] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] figure 1 A wireless communication system is shown in which the present invention may be implemented.

[0041] Such as figure 1 As shown, the wireless communication system 100 includes a first base station 110 corresponding to a first cell, a second base station 120 corresponding to a second cell, and user equipments 130 and 140 .

[0042] The first base station 110 provides a first coverage area 110-a and the second base station 120 provides a second coverage area 120-a.

[0043] Here, it is assumed that the user equipment 130 is within the first coverage area 110-a. Accordingly, the user equipment 130 communicates with the first base station 110 via the wireless link 150 . The user equipment 140 is within the second coverage area 120-a. Accordingly, the user equipment 140 communicates with the second base station 120 via the wireless link 160 ...

Abstract

The invention discloses a method and device for monitoring high speed shared control channel (HS-SCCH) in a radio communication system. In the invention, current state has to be determined first, and corresponding monitoring process is carried out according to the state determined. wherein the current state is any one of a null state, an active state, a inactive state and a discontinuous receiving state, monitoring is not conducted under the null state, monitoring is conducted under the active state and the inactive state, and the discontinuous monitoring is conducted under the discontinuous receiving state according to discontinuous receiving parameters. According to the invention, the UE power consumption with low on-line requirement for a long time is lowered. On the other hand, frequently starting up an inactive timer is prevented.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 61 / 611,455, filed March 15, 2012, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the present invention relate to a wireless communication system, and in particular to a method and a device for monitoring a high-speed shared control channel HS-SCCH. Background technique [0004] High-speed packet access HSPA is a collection of a series of enhanced technologies, including shared channel transmission, shorter transmission time interval TTI, fast link adaptation, hybrid automatic retransmission combined with soft combining, centralized scheduling, high-order modulation, etc. The transmission parameters are dynamically adjusted according to the current channel conditions, thereby greatly improving the throughput and peak rate of the system. [0005] For some services that are online for ...
