Problems solved by technology

If the network does not adjust the UE's blind detection mode at this time, the bandwidth of the UE's blind detection resources will be much greater than the actual service rate
[0049] Also, contrary to the above situation, compared to a blind detection pattern, when the traffic rate increases for a long time (such as hundreds of subframes, several seconds, or even tens of seconds), for example, the user switches from a voice VoIP phone to a video Telephone, it will cause the bandwidth of UE blind detection resources to be much smaller than the actual service rate, if not adjusted in time, it will cause service data transmission delay

Embodiment Construction

[0067] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0068]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.

[0069] In the present invention, the network or communication protocol configures the physical resources for blind detection of UE in a specific subframe (or frame, TTI, period), which is called "blind detection pattern" or "predefined pattern"; if HS-SCCH The scheduled HS-PDSCH is located in the i-th subframe (or frame, TTI), it is said that the U...

Abstract

The invention relates to a time division-synchronous code division multiple access system, and discloses a blind detection dispatching method and blind detection dispatching equipment for the time division-synchronous code division multiple access system. The method and the equipment can save the electric energy of a terminal under the condition of ensuring the service transmission. The method comprises the following steps: measuring preset blind detection parameters of specific user equipment first; and if the measuring result meets the preset conditions, changing the density of blind detection frequency and blind detection resources of the user equipment.

Description

technical field [0001] The invention relates to a time division synchronous code division multiple access system, in particular to a blind detection technology in the time division synchronous code division multiple access system. Background technique [0002] With the continuous development of communication technology and the increasing requirements of users for service quality, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as "3GPP") standard defined data up to 2Mbit / s before Release 4. The transmission rate has gradually been unable to meet the needs of users 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 obtain lower time delay, higher system th...
