Problems solved by technology

When faced with different application scenarios in the future network system, if frequency hopping technology is used for all application scenarios, the flexibility of frequency hopping is poor, which may lead to poor system performance. For example, in some application scenarios In this case, the diversity gain can be obtained without frequency hopping technology, but the frequency hopping technology is still used, then the reference signal required for frequency hopping will occupy a certain amount of resources, resulting in a large resource overhead

Abstract

The embodiment of the invention provides an information transmission method, comprising the following steps: determining whether terminal equipment sends uplink control channel PUCCH information to network equipment in a frequency hopping way by the network equipment; when the network equipment determines a fact that the terminal equipment sends the PUCCH information to the network equipment in the frequency hopping way, receiving the PUCCH information sent by the terminal equipment in the frequency hopping way by the network equipment; and when the network equipment determines a fact that theterminal equipment sends the PUCCH information to the network equipment in a no-frequency-hopping way, receiving the PUCCH information sent by the terminal equipment in the no-frequency-hopping way by the network equipment, thus resource overhead can be reduced, and system performance can be beneficially improved.

Description

technical field [0001] The present application relates to the field of communications, and more particularly, to methods and devices for transmitting information in the field of communications. Background technique [0002] A frequency hopping (frequency hopping, FH) technology is to modulate transmitted data in different frequency bands for transmission, so as to obtain frequency diversity gain. In a long term evolution (long term evolution, LTE) system, both an uplink shared channel (physical uplink share channel, PUSCH) and an uplink control channel (physical uplink control channel, PUCCH) adopt frequency hopping technology. When faced with different application scenarios in the future network system, if frequency hopping technology is used for all application scenarios, the flexibility of frequency hopping is poor, which may lead to poor system performance. For example, in some application scenarios In this case, the diversity gain can be obtained without the frequency ...
