Embodiment Construction
[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0056] In order to ensure the service needs of users in areas with weaker signal coverage, users are usually assigned a frequency point to perform repeated multi-frame service transmission on a certain bandwidth. However, if the frequency point is in a large interference scenario, even repeated multi-frame transmission cannot meet the demodulation...

The embodiment of the invention provides an information sending and receiving method and device, and the method comprises the steps: obtaining a physical sub-band number corresponding to each sub-frame number under each frame number, wherein the same subframe number under different frame numbers corresponds to different physical sub-band numbers; and based on the physical sub-band number corresponding to each sub-frame number under each frame number, repeatedly sending the wireless frame by taking the sub-frame as a unit, so that a receiving end can receive and restore the wireless frame basedon the physical sub-band number corresponding to each sub-frame number under each frame number. According to the method and the device provided by the embodiment of the invention, wireless frame sending and receiving are realized on the basis of the physical sub-band number corresponding to each sub-frame number under each frame number, and the same sub-frame in the wireless frame is transmittedthrough different physical sub-bands, so that the transmission failure risk caused by transmitting information through a single physical sub-band is avoided, and the effectiveness of information transmission is ensured.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to an information sending and receiving method and device. Background technique [0002] The development of mobile communication technology meets the needs of users for wireless data transmission. However, in the edge area of the cell, or some special places, such as the basement, under the manhole cover, etc., the transmission power of the existing cell is difficult to cover all users, and the user may not be able to access the network due to weak signal coverage in the above areas. . [0003] Adding a community site can solve the above problems. However, adding a cell site will increase the cost of network construction, and the cost performance is low. Therefore, when a user located in the above-mentioned area has a service requirement, a frequency point is usually allocated to the user, and repeated multi-frame service transmission is performed on a cert...
