Method and device for transmitting information

Abstract

The present disclosure provides a method and device for transmitting information, wherein the above method includes: determining the frequency information of the second carrier used to carry subsequent scheduling data information; determining the current radio frequency support capability of the user equipment; if the first The frequency of the second carrier exceeds the current radio frequency support capability of the user equipment, sending the scheduling information of the second carrier to the user equipment through the first carrier; according to the scheduling information of the second carrier, through the second The carrier continues to transmit information to the user equipment. By adopting the method for transmitting information provided in the present disclosure, it is possible to reduce the failure of user equipment to receive subsequent scheduling information due to a large carrier span, avoid unnecessary retransmission, and save system resources.

Description

technical field [0001] The present disclosure relates to the field of communication technology, and in particular, to a method and device for transmitting information. Background technique [0002] With the development of wireless communication technology, mobile communication networks are gradually evolving to 5G networks. One of the key technologies of the 5G network communication system is to use high-frequency wireless resources such as frequencies above 6GHz for data transmission. In a 5G network, the bandwidth of a single-band band will be close to 1GHz, and the bandwidth level of a single carrier will be between 80MHz and 400MHz. In the related 4G network LTE (Long Term Evolutions, long-term evolution) system, the bandwidth of a single-band band generally does not exceed 200MHz, and the bandwidth level of a single carrier is: 1.4MHz to 20MHz. Therefore, compared with the 4G network LTE system, the 5G network puts forward higher requirements for the transmission capab...

Problems solved by technology

[0004] However, it takes time for the user equipment to switch the RF transceiver module. Although the switching delay between modules has been shortened to milliseconds, since the duration of a subframe in the 5G system is 1ms, the user equipment needs to switch between the RF transceiver modules. During this period, the reception of some downlink information may be missed. If the missed downlink information belongs to the scheduling control information of the subsequent scheduling, the subsequent scheduling data will not be received normally, which will inevitably lead to many unnecessary retransmissions and waste system resources.
