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 invention provides a method for indicating a radio frequency (RF) block in an MTC system. The method comprises the steps of determining the bandwidth of an RF block during the next transmission process, wherein the bandwidth of the RF block identifies the location of the RF block in the entire system bandwidth; during the current transmission, transmitting a predetermined physical downlink control channel, wherein the downlink control information transmitted via the predetermined physical downlink control channel contains the determined bandwidth of the RF block during the next transmission process and resources for a physical downlink shared control channel (PDSCH) during the current transmission process or the next transmission process, and the physical downlink control channel can be an EPDCCH or a machine type communication specific PDCCH; and transmitting the predetermined physical downlink control channel and / or the PDSCH during the next transmission process at the bandwidth of the RF block.

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 of low-cost MTCUE has reached a conclusion at present, and its purpose is to reduce the cost of MTCUE, so that it is more competitive compared with other technologies. Since there is currently strong support for further reducing the cost of these devices, it is likely that the design of low-cost MTCUEs will continue in Rel-13. One of the main proposals to reduce the cost of MTCUEs is to reduce the radio frequency (RF) bandwidth of these devices, that is, to limit the MTCUEs to operate on the 1.4MHz bandwidth. Contents of the invention [0003] It ...
