Embodiment 1

[0068] Embodiment one, such as Figure 4 As shown, the step 304 may specifically include the following process steps:

[0069] Step S40, detecting whether the terminal is in a cell edge area.

[0070] Step S42, if it is detected that the terminal is in the cell edge area, then determine that the terminal is the target terminal, so as to perform the step of placing the downlink control information transmitted in the flexible subframe m of the uplink spectrum resource in the downlink of the downlink spectrum resource Steps for transmission in subframe m.

[0071] In this embodiment, it is possible to determine whether the terminal is a terminal that is easily affected by uplink and downlink interleaving interference by detecting whether the terminal is located in the edge area of ​​the cell, that is, by locating the specific location information of the terminal, if the terminal is detected In the cell edge area, it is determined as the target terminal, that is, the downlink co...

Embodiment 2

[0073] Embodiment two, such as Figure 5 As shown, the step 304 may specifically include the following process steps:

[0074] Step S50, receiving the interference value reported by the terminal on the flexible subframe m of the uplink spectrum resource.

[0075] Step S52, judging whether the interference value is greater than a preset interference threshold.

[0076] Step S54, if it is determined that the interference value is greater than the preset interference threshold value, then determine that the terminal is the target terminal, so as to execute the step of putting the downlink control information transmitted in the flexible subframe m of the uplink spectrum resource into A step of transmitting in the downlink subframe m of the downlink spectrum resource.

[0077]In this embodiment, the interference value detected and reported by the terminal on the flexible subframe m of the uplink spectrum resource can be received, and then according to the comparison result betwee...

Abstract

The invention provides a communication method and device in a flexible duplex system. The method comprises the following steps: setting a part of sub-frames in an uplink spectrum resource as flexible sub-frames for transmitting downlink data, and retaining the other part of sub-frames in the uplink spectrum resource as non-flexible sub-frames for transmitting uplink data; detecting whether a terminal is a target terminal; and if the terminal is the target terminal, transmitting downlink control information transmitted in the flexible sub-frames m of the uplink spectrum resource in downlink sub-frames m of a downlink spectrum resource, wherein m is not smaller than 0 and is not greater than 9 and is an integer. By adoption of the technical scheme of the invention, strong uplink and downlink cross interference to the downlink control information can be effectively protected, and thus the data information sent by a base station to the terminal on the flexible sub-frames is demodulated.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a communication method in a flexible duplex system and a communication device in the flexible duplex system. Background technique [0002] The current 5th generation mobile communication system (5G, 5th-Generation) is being researched in academia and industry. Among them, the ultra-dense network (Ultra-Dense Network, UDN) is an important technology of 5G. UDN refers to the scenario of large data demand and large number of data connections during network deployment (such as sports stadiums, railway stations, etc.) Waiting halls, office spaces, etc.), for ultra-dense networking, the interval between access sites may only be tens of meters. A technology that may be used in UDN scenarios is Flexible Duplex, that is, according to service requirements, downlink services are carried on certain subframes of uplink spectrum resources in an FDD (Frequency Division Duplexing...
