Problems solved by technology

[0004] However, in the prior art, there is no provision for the situation that the subframe does not contain DCI, and the UE usually keeps the downlink reception turned on
However, when there is no DCI, the UE does not need to process the data area of ​​the subframe, which will result in wasted power consumption for receiving the data area of ​​the subframe

Embodiment Construction

[0030] As mentioned above, in LTE / LTE-A, power consumption optimization of UE in connected state is very important. Specifically, there are many factors that determine power consumption, and the scheduling rate of uplink and downlink services, and the power consumption of RF and baseband processing are all important factors.

[0031] combined reference figure 1 with figure 2 , figure 1 It is a schematic diagram of a work flow of a downlink PDSCH traffic channel in the prior art; figure 2 It is a schematic diagram of a working scenario of a downlink PDSCH service channel in the prior art.

[0032] For LTE UEs, after entering the connected state, PCFICH processing 11 needs to be performed first in all possible downlink subframes, wherein PCFICH processing can also be called CFI decoding, specifically, the physical control format of symbol 0 (SYMBOL0) is determined Control Format Indicator (Control Format Indicator, CFI) information of a Physical Control Format Indicator Ch...

Abstract

Provided are a subframe receiving method and device, a storage medium and a user terminal. The method may include: receiving at least a part of a control area of a subframe, and decoding the receivedat least a part of the control area to determine whether DCI is included, the subframe including the control area and a data area; and in response to the fact that the DCI is not included in the sub-frame, closing reception of at least one part of a data area of the sub-frame. The scheme of the invention can effectively reduce power consumption.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a subframe receiving method and device, a storage medium, and a user terminal. Background technique [0002] In the long term evolution (Long Term Evolution, LTE) / LTE evolution version (LTE-Advanced, LTE-A), the power consumption optimization of the user terminal (User Equipment, UE) in the connected state is very important, and each operator has formulated Strict power consumption standards, for Voice over Long-Term Evolution (VoLTE), the corresponding indicators given by the terminal power consumption under data download; and with the advancement of chip technology and the maturity of terminal technology, power consumption The indicator shows a further downward trend to improve the user experience in actual use. [0003] For downlink subframes, there are cases where the subframe contains downlink control information (Downlink Control Information, DCI) and ...
