An information transmission method, base station, and user equipment

Abstract

An information transmission method, base station, and user equipment, wherein an information transmission method includes: receiving a random access preamble sent by a user equipment UE; generating first information according to the received random access preamble, wherein, The first information is random access response information for the random access preamble, and the first information includes at least one of the following information: timing advance indication information, indication information of narrowband resources used for control channel transmission, The indication information of the subframe used for the control channel transmission, the indication information of the demodulation reference signal scrambling sequence initialization parameter used for the control channel transmission, the indication information of the coverage enhancement level used for the control channel transmission, and the second information transmitting used resource allocation information, where the second information is response information to the first information; and sending the first information to the UE.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to an information transmission method, a base station, and user equipment. Background technique [0002] The Internet of Things refers to a network that obtains information in the physical world by deploying various devices with certain perception, calculation, execution and communication capabilities, and realizes information transmission, collaboration and processing through the network, thereby realizing the interconnection of people and things, and things and things. . In short, the Internet of Things is to realize the interconnection between people and things, things and things. Possible applications include various aspects such as smart grid, smart agriculture, smart transportation, and environmental detection.

Problems solved by technology

[0005] In the scenario where coverage enhancement transmission is required for the random access response, the RAR message in the prior art contains too much information content, and a large number of repetitions are required during coverage enhancement transmission, which greatly increases the complexity of UE detection degree, increasing the UE's power consumption overhead

For example, in the prior art, one or more RARs may be included in a RAR message, and the information content included in one RAR occupies at least 7 bytes (that is, 56 bits), which makes the load of the RAR message too large

In the scenario where coverage-enhanced transmission of RAR messages is required, taking coverage-enhanced transmission as repeated transmission as an example, the number of random access opportunities within the same time resource will be reduced. If the existing RAR message is still used, it will inevitably lead to RAR The resource utilization efficiency of the message is reduced, and the power consumption overhead of the user equipment detection channel is still large
