Blind test feedback of time division synchronous code division multiple access system and method for receiving same

Abstract

The invention relates to a time division synchronous code division multiple access system, and in particular discloses a blind test feedback of the time division synchronous code division multiple access system and a method for receiving the same. The method comprises the following steps that: configuring HS-SICH corresponding to pre-defining resources of the blind test on UE by a network, simultaneously setting the timing sequence relationship of the pre-defining resources and the HS-SICH, thereby avoiding the conflict between the pre-defining resources and the HS-SICH with current configuration, reducing the waste of signaling resources and improving system capacity. The HS-SICH which does not correspond to the HS-SCCH can be configured to correspond to the pre-defining resources of theblind test, or the HS-SICH also corresponds to the HS-SCCH while corresponding to the pre-defining resources of the blind test, the HS-SCCH is given up for scheduling, and the physical resources of the HS-SCCH given up is used for sending other data except the HS-SCCH.

Description

technical field [0001] The present invention relates to a time division synchronous code division multiple access (Time Division Synchronous Code Division Multiple Access, referred to as "TD-SCDMA") system, in particular to a blind detection technology in the TD-SCDMA system. Background technique [0002] With the continuous development of communication technology and the increasing requirements of users on service quality, the data transmission rate defined by the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") standard before Release 4 has gradually failed to meet the needs of users. The demand for high-speed data services. In this case, 3GPP introduced a High Speed ​​Downlink Packet Access (High Speed ​​Downlink Packet Access, "HSDPA" for short) technology in the Release 5 specification. [0003] HSDPA is an enhanced solution proposed by 3GPP Release 5, the main purpose is to support high-speed packet data services, and to o...

Problems solved by technology

See Table 3. The HS-SCCH less information information element is only configured with predefined blind detection resources, but the HS-SICH corresponding to this resource is not configured in the existing protocol. Therefore, after the blind detection, the UE will not be able to determine On which HS-SICH to feed back information

[0069] In addition, if it is stipulated that the HS-SICH used for the feedback information after the blind detection is the same as one of the HS-SICHs configured in the current HS-SCCH info element when the HS-SCCH Less operation is transmitted for the first time, the HS-SICH Paired HS-SCCH unavailable

Because at this time, if the network uses the HS-SCCH to schedule another UE to receive, the new UE may use the same HS-SICH feedback information as the UE performing blind detection, which will waste HS-SCCH resources and reduce system capacity
