Embodiment Construction

[0023] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In addition, for ease of description, various embodiments of the present invention will be described by taking the EPDCCH as an example of a predetermined physical downlink control channel. Those skilled in the art can understand that the predetermined physical downlink control signal involved in the present invention may also include a dedicated PDCCH for machine type communication that may appear during the development of future communication technologies.

[0024] refer to figure 1 , in step S101, the base station determines the bandwidth of the RF block used for the next transmission. The bandwidth of an RF block identifies the position of the RF block in the overall system bandwidth.

[0025] For example, the base station may determine the bandwidth of the RF block used for the next transmission based on the channel quality indicator (CQI) i...

Abstract

The present invention provides a method for indicating a radio frequency block in a MTC system, comprising: determining a bandwidth of a radio frequency block for next transmission, the bandwidth of the radio frequency block identifying a location of the radio frequency block in the entire system bandwidth; transmitting a predetermined physical downlink control channel upon current transmission, downlink control information of the predetermined physical downlink control channel including the determined bandwidth of the radio frequency block for next transmission and a resource used by PDSCH in the current transmission or next transmission, the predefined physical downlink control channel being an EPDCCH or machine type communication-specific PDCCH; and transmitting the predetermined physical downlink control channel and / or PDSCH on the bandwidth of the radio frequency block at next transmission.

Description

technical field [0001] The present invention relates to a communication system based on machine type communication, in particular to a method and a device for indicating a radio frequency block in the communication system based on machine type communication. Background technique [0002] A Machine Type Communication (MTC) device is a user equipment (UE) used by a machine for a specific application. In 3GPP Rel-12, the work item on low-cost MTC UE has been concluded, and its purpose is to reduce the cost of MTC UE to make it more competitive compared with other technologies. Since there is currently strong support for further cost reduction of these devices, it is very likely that the design of low-cost MTC UEs will continue in Rel-13. One of the main proposals to reduce the cost of MTC UEs is to reduce the radio frequency (RF) bandwidth of these devices, that is, to limit the MTC UEs to operate on the 1.4 MHz bandwidth. Contents of the invention [0003] It can be expect...
