Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0026] For the sake of description, in the embodiments of the present invention, the "configuration parameter of the interception reference signal" is simply referred to as the "configuration parameter".

[0027] The first embodiment of the present invention relates to a method for sending an interception reference signal. In this embodiment, before the network side sends the configuration parameters to the UE, the UE first obtains the frequency-domain selective fading of the current channel according to the measurement. In this case, send configuration parameters for reference to the network side. The network side then determines the configuration parameters to be sent to the UE according to the configuration parameters from the UE and ...

Abstract

The invention relates to a wireless communication system and discloses a method for sending interception reference signal and a device thereof, which can cause user equipment to effectively send the interception reference signal. The user equipment can send the interception reference signal according to or referring to the configuration parameters from a network side. An interaction process about the configuration parameters of the interception reference signal is arranged between the network side and the user equipment. The configuration parameter for sending the interception reference signal can be sent in process of random access, or sent in broadcast signaling or paging signaling, or sent in RRC special process, or sent in layer 1 or layer 2 signaling, or sent in the switching process.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to wireless resource scheduling technology. Background technique [0002] With the development of communication technologies, a third-generation mobile communication system has emerged in the communication field: Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, referred to as "UMTS"). In UMTS, both uplink and downlink adopt Code Division Multiple Access (CDMA for short) technology. [0003] In order to meet many data services with high traffic and delay requirements, such as video, streaming media and downloading, etc., High Speed ​​Uplink Packet Access (HSUPA for short) is used as the evolution of the uplink in UMTS standard. HSUPA achieves fast adaptive control by using shorter Transmission Timing Interval (Transmission Timing Interval, referred to as "TTI") and frame length (2ms or 10ms), and uses Hybrid Automatic Repeat Request (...
