Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] figure 1 It is a schematic flowchart of a method for reporting a subband CQI in an LC-MTC (Low Cost Machine Type Communication, Low Cost MTC) user equipment according to an embodiment of the present invention. Wherein, the method in this embodiment is mainly implemented by LC-MTC user equipment, and the LC-MTC user equipment may be any user equipment supporting LC-MTC, such as a smart meter. In the scenario of this embodiment, the network where the LC-MTC user equipment is currently located does not support LC-MTC configuration; where the LC-MTC user equipment can determine the SIB (system information block, system information block) by reading Whether the network where the LC-MTC user equipment is currently located supports LC-MTC configuration.

[0023] It should be noted that the LC-MTC user equipment described is only an example, and other existi...

Abstract

Provide a method of reporting CQI in LCcMTC user devices. Among them, the current network of LC‑MTC user devices does not support LC‑MTC configuration, which includes the following steps: a. Based on the current CQI -based CQIReport the configuration to determine the multiple sub -bands that need to be reported to the base station and the candidate belt in the multiple sub -bands. Among them, the number of candidate bands does not exceed the upper limit of the number of sub -bands supported by the LC‑MTC user device;. Set the CQI deviation of the candidate strap to a higher CQI deviation, and set the CQI deviation of other sub -bands in the multiple sub -bands to a lower CQI deviation; c.The deviation is reported to the base station of the user device.According to the plan of the present invention, more effective scheduling bandwidth user equipment can be scheduled in the traditional network.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and equipment for reporting subband CQI in LC-MTC user equipment. Background technique [0002] In the prior art, generally, the user equipment receives the PDCCH in the first few (such as the first 1 to 3) OFDM symbols in a subframe, and then receives the concerned PDSCH PRB in the subsequent OFDM symbols in the same subframe. Since the UE cannot decode PDCCH immediately, it needs to store a PRB of full bandwidth value so that it can decode PDSCH after decoding PDCCH. This has certain requirements on the bandwidth of the user equipment. If the bandwidth of the user equipment is less than the full bandwidth value that needs to be stored, data cannot be received or sent correctly on the LC-MTC user equipment. [0003] However, in certain occasions, the bandwidth of the user equipment will be limited. For example, in order to reduce costs, the band...
