AI Technical Summary

Problems solved by technology

It can be seen that in the current TD-SCDMA system, there is no situation where the symbols used for uplink channel estimation are carried in the Midamble domain and sent separately, that is, there is no SRS, and of course there is no corresponding SRS implementation plan

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0044] figure 1 It is an exemplary flow chart of the method for implementing the SRS in the TD-SCDMA system in the embodiment of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0045] Step 101, the network side configures SRS resource information for the user equipment UE, and notifies the UE of the configured SRS resource information.

[0046] Among them, according to different application scenarios, the allocation of SRS can be divided into user-level configuration (UE specific) or cell-level configuration (cell specific). The two distribution methods are described in detail below:

[0047] (1) User-level SRS allocation: UE as a unit, when the UE service is initiated and a service connection is es...

Abstract

The invention discloses an up-going reference mark signal (sounding RS and SRS) realizing method in a time division synchronization code division multiple access (TD-SCDMA) system. The realizing method comprises the steps that a network side configures SRS resource information for user equipment user experience (UE), the configured SRS resource information is informed to the UE, and the UE sends the SRS according to the SRS resource information. According to the technical scheme, sending of the SRS can be achieved in the TD-SCDMA system.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for realizing an uplink reference symbol in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system. Background technique [0002] In the mobile communication system, in order to realize high-speed data transmission, high-speed packet access (HSPA) technology is introduced. HSPA technology includes high-speed downlink packet access (HSDPA) technology and / or high-speed uplink packet access (HSUPA) technology. [0003] Among them, HSUPA includes four physical channels, namely enhanced dedicated channel (E-DCH, Enhanced Dedicated Channel) physical uplink channel (E-PUCH, E-DCH Physical Uplink Channel), E-DCH absolute authorization channel (E-AGCH, E -DCH Absolute Grant Channel), E-DCH Hybrid Automatic Repeater Indicator Channel (E-HICH, E-DCH Hybrid ARQ Indicator Channel) and E-DCH Random Access Uplink Control Channel (E-RUCCH, E-DCH Random Access Uplin...
