Embodiment 1

[0060] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of a method for configuring uplink and downlink subframes based on TD-LTE according to the embodiment of the present invention.

[0061] In Embodiment 1, the method for configuring uplink and downlink subframes based on TD-LTE includes:

[0062] Step 101, obtain preset rules for configuring uplink and downlink subframes, the rules include setting up and downlink subframe rules according to the relationship between the bit ratio of uplink and downlink subframes and fixed comparison parameters, or include setting up and downlink subframes according to the The bit ratio of the row subframe sets the rules for the uplink and downlink subframes;

[0063] Specifically, the ratio of the number of uplink buffer bits scheduler_buffer_ul to the number of downlink buffer bits scheduler_buffer_dl at the Nth time of the preset TTI is compared with the fixed parameter to determine the TTI subframe at th...

Embodiment 2

[0071] refer to figure 2 , figure 2 It is a schematic flowchart of the second embodiment of a method for configuring uplink and downlink subframes based on TD-LTE according to the embodiment of the present invention.

[0072] In Embodiment 2, the method for configuring uplink and downlink subframes based on TD-LTE includes:

[0073] Step 201, obtaining preset rules for configuring uplink and downlink subframes, the rules include setting rules for uplink and downlink subframes according to the relationship between the bit ratio of uplink and downlink subframes and the fixed comparison parameter;

[0074] Specifically, the ratio of the number of uplink buffer bits scheduler_buffer_ul to the number of downlink buffer bits scheduler_buffer_dl at the Nth time of the preset TTI is compared with the fixed parameter to determine the TTI subframe at the N+4th time.

[0075] Step 202, obtaining the bit ratio of the uplink and downlink subframes, the bit ratio of the uplink and downl...

Embodiment 3

[0091] refer to image 3 , image 3 It is a schematic flowchart of the third embodiment of a method for configuring uplink and downlink subframes based on TD-LTE according to the embodiment of the present invention.

[0092] In Embodiment 3, the method for configuring uplink and downlink subframes based on TD-LTE includes:

[0093] Step 301, obtaining preset rules for configuring uplink and downlink subframes, the rules include rules for setting uplink and downlink subframes according to the bit ratio of the uplink and downlink subframes;

[0094] Specifically, count the ratio of the total number of bits to be transmitted scheduler_buffer_ul in the uplink buffer and the total number of bits to be transmitted in the downlink buffer scheduler_buffer_dl at the Nth moment of the preset TTI, and take 10 TTIs as the cycle according to the ratio of uplink and downlink bits at the Nth moment Configuring subframes can reduce the situation of connecting U / connecting D.

Abstract

The embodiment of the present invention discloses a method and device for configuring uplink and downlink subframes based on TD-LTE, which obtains preset rules for configuring uplink and downlink subframes; obtains the bit ratio of the uplink and downlink subframes, and the uplink and downlink subframes The bit ratio includes the bit ratio of the uplink and downlink subframes at the Nth moment of the preset TTI; the uplink and downlink subframes are configured according to the bit ratio of the uplink and downlink subframes and the rules, so as to interfere with the TDD time division multiplexing base station including the LAA base station, etc. The measurement and feedback of the environment and business types, and the flexible and dynamic adaptive configuration of the TDD uplink and downlink subframe ratios of different cells on the unlicensed frequency band, so as to improve the efficiency of wireless communication resources, enhance the business optimization capabilities of TDD cells, and improve The purpose of the energy efficiency of the access network.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for configuring uplink and downlink subframes. Background technique [0002] With the development of Internet technology, the volume of communication services will increase dramatically, and the types of services will become more varied. In the LAA micro-cell environment, due to the small number of users in the cell and the sudden nature of the uplink and downlink services with the development of data services, it is difficult to maintain a stable business ratio between the uplink and downlink services. In this case, the existing static uplink and downlink subframe configuration methods cannot well adapt to the changes brought about by the suddenness of such services, which is likely to cause waste of resources and decrease in spectrum efficiency, and it is also not very good. Give full play to the characteristics and advant...
