Problems solved by technology
[0013] However, the additional storage space may be comparable to the inherent storage space needed to maintain the normal sliding window for the normal application scenario, that is, the time when the control processing does not occur, resulting in at least 1 times the storage cost, especially for the receiver. It is unaffordable for terminal receivers that are extremely cost- and cost-sensitive
[0014] During the research and practice of existing methods, the inventors of the present invention found that there is a significant contradiction between ensuring the performance of channel estimation in the prior art and the control processing frequency requirements of mobile communication systems, so that channel estimation is constantly disturbed by control processing and difficult Play the expected effect, or pay a large cost to ensure the performance of channel estimation

The invention discloses a control time selection method and device, and a control method in a mobile communication system. The control time selection method detects whether concurrent services exist in a subframe and if the concurrent services do not exist in the subframe, at least one of non-concurrent-service generating times is selected as a control time and if the concurrent services exist in the subframe, at least one of preset times is selected as a control time. Because it is sure that a free space exists in a storage space at the non-concurrent-service generating times, a space is provided to storage needed by control operations and thus it is ensured that performance damages on channel estimation when control happens are small.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and control method for controlling time selection in a mobile communication system. Background technique [0002] In the mobile communication system, in order to adapt to the characteristics of the frequency / time selectivity of the wireless channel, the stability of the device / device, and the large dynamic range of the signal strength, the data receiver introduces automatic frequency control (Automatic Frequency control, referred to as AFC), Timing synchronization control, automatic gain control (Automatic Gain Control, referred to as AGC) and other control processing are used to ensure stable and reliable reception. [0003] Taking the 3rd Generation Partnership Long Term Evolution (LTE) system as an example, usually the receiver has the following reception processing methods: [0004] A. N receiving antennas implement Orthogonal Frequency Divisi...
