Problems solved by technology

[0003] However, for terminals, limited by the cost and size of the terminal, the attenuation capability of the filter is relatively poor. When the network side simultaneously schedules two cross-band TDD carriers with opposite information When the physical location of the carrier is far away, the transmission on one carrier will not affect the reception of the other carrier. However, if the physical distance between the two carriers aggregated across frequency bands is close, the transmission on one carrier will cause the other carrier to fail to receive. Information, the two carriers scheduled by the network side for the terminal interfere with each other in the terminal, reducing the efficiency of information transmission

Abstract

Disclosed are a transmission resource allocation method, device and system, and base station equipment, which are used for avoiding the mutual interference of two carriers in a terminal when any two carriers are used to simultaneously transmit information in opposite directions and increasing the information transmission efficiency. The transmission resource allocation method comprises: when it is judged that the transmission directions of information which are borne in a first carrier and a second carrier simultaneously scheduled for a terminal at a scheduling moment are opposite, determining a time-domain resource occupied by the information borne in the first carrier; and determining the time-domain resource except the time-domain resource occupied by the information borne in the first carrier as an available time-domain resource of the second carrier.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a transmission resource allocation method, device, system and base station equipment. Background technique [0002] With the development of time division duplex (TDD, Time Division Duplexing) cross-band carrier aggregation technology, the current network side has been able to support simultaneous information transmission on two TDD carriers aggregated across frequency bands, that is, the network side supports simultaneous transmission and reception. Features. Such as figure 1 As shown, it is a schematic diagram of information transmission at a certain scheduling moment in the cross-band carrier aggregation scenario, in which, in the five 1ms subframes contained in the current 5ms frame, in the third subframe, the information transmission direction on carrier 1 is For uplink, the direction of information transmission on carrier 2 and carrier 3 is downlink....
