Problems solved by technology

In addition, MTC equipment can only receive 6 PRBs, so for a 20MHz system, the bandwidth of 20MHz can be divided into 17 MTC sub-bands. provide enough variety
Therefore, the existing PUSCH frequency hopping scheme is not suitable for low-cost MTC equipment

Abstract

The invention relates to a method and device for assisting MTC equipment in implementing data transmission in a base station, and a method and equipment for implementing data transmission in MTC equipment. The method for assisting the MTC device in the base station to implement data transmission includes the steps: A. dividing the available frequency band of the MTC to determine a plurality of candidate subbands; B. forming a set of subbands for the MTC device; C. determining whether there is a need to perform hopping frequency hopping MTC equipment, when it exists; C1. assign a set offset for each MTC equipment that needs to implement frequency hopping; C2. determine a continuous transmission value for each MTC equipment that needs to implement frequency hopping; C3. The subband set, the set offset and the continuous transmission value are sent to the corresponding MTC device; C4. Implement data transmission with the MTC device; C5. Based on the channel quality and / or of each subband in the subband set or subband occupancy, select a new subband to replace a subband with poor channel quality and / or a subband to be occupied by a non-MTC device in the subband set.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular, the present invention relates to a method and device for assisting MTC equipment in implementing data transmission in a base station, and a method and equipment for implementing data transmission in MTC equipment. Background technique [0002] In Rel-13, the MTC (Machine Type Communication) work item has been agreed upon, and further reduction of the complexity at the user end of the MTC device is required. In order to increase the coverage strength of the user end of the MTC device and improve power consumption. The low-cost MTC user end can be equipped with a lower power amplifier, which will cause loss of coverage performance, so it is necessary to increase the signal coverage strength by about 18dB. The most effective coverage enhancement technique is repetition. For an enhancement of 18dB coverage, more than 300 retransmissions need to be performed. This greatl...
