Abstract
Provided are a data sending and receiving method, an apparatus, a system, a terminal, a base station and a storage medium. Data carried in a non-Long-Term Evolution (non-LTE) downlink control region of a subframe is mapped to an LTE downlink control region of the subframe, and data carried in the non-LTE downlink control region and the LTE downlink control region of the subframe is sent to an MTC terminal.
Claims18
A data sending method, comprising:
- mapping data carried in a non-Long-Term Evolution (non-LTE) downlink control region of a subframe to an LTE downlink control region of the subframe;
- and
- sending data carried in the non-LTE downlink control region and the LTE downlink control region of the subframe to a machine-type communication (MTC) terminal;
- wherein mapping the data carried in the non-LTE downlink control region of the subframe to the LTE downlink control region of the subframe comprises:
- determining an index of an orthogonal frequency-division multiplexing (OFDM) symbol to be mapped in the non-LTE downlink control region based on a sequence number of resending of the data carried in the non-LTE downlink control region, and mapping data on the OFDM symbol corresponding to the index to the LTE downlink control region.

A data sending and receiving method, comprising:
- mapping, by a base station, data carried in a non-Long-Term Evolution (non-LTE) downlink control region of a subframe to an LTE downlink control region of the subframe;
- sending, by the base station, data carried in the non-LTE downlink control region and the LTE downlink control region of the subframe to a machine-type communication (MTC) terminal;
- receiving, by the MTC terminal, the data carried in the non-LTE downlink control region and the LTE downlink control region of the subframe;
- determining, by the MTC terminal, mapped data that is carried in the LTE downlink control region and mapped from the non-LTE downlink control region;
- and
- merging, by the MTC terminal, the mapped data with data carried in the LTE downlink control region;
- wherein mapping the data carried in the non-LTE downlink control region of the subframe to the LTE downlink control region of the subframe comprises:
- determining an index of an orthogonal frequency-division multiplexing (OFDM) symbol to be mapped in the non-LTE downlink control region based on a sequence number of resending of the data carried in the non-LTE downlink control region, and mapping data on the OFDM symbol corresponding to the index to the LTE downlink control region;
- and
- wherein determining the mapped data that is carried in the LTE downlink control region and mapped from the non-LTE downlink control region comprises:
- determining an index of an orthogonal frequency-division multiplexing (OFDM) symbol that is mapped from the non-LTE downlink control region to the LTE downlink control region based on a sequence number of resending of data carried in the non-LTE downlink control region, and using data on the OFDM symbol corresponding to the index as the mapped data.
