Embodiment 1

[0041] ginseng figure 1 As shown, Embodiment 1 provides a method for differentiated scheduling based on SRS. Embodiment 1 uses two user equipments as an example to illustrate the implementation details of the algorithm. Of course, it is not limited to two UEs, including:

[0042] S101. Receive full-bandwidth channel sounding reference SRS signals sent by multiple user equipments.

[0043] Wherein, in step 1, the uplink channel sounding reference SRS signal uses the ZC sequence as the base sequence and generates it for the operation through a loop.

[0044] S102. According to the channel quality of the channel sounding reference SRS signal, determine the interfered resource block RB and the non-interfered resource block RB of each user equipment.

[0045] For example: according to the channel quality of the channel sounding reference SRS signal, it can be determined whether the resource block has a used part to determine whether it is interfered, and through statistics and det...

Embodiment 2

[0071] refer to figure 2 , the present invention provides a system based on SRS differentiated scheduling, including:

[0072] A signal receiving module 201, configured to receive full-bandwidth channel sounding reference SRS signals sent by multiple user equipments;

[0073] A resource block RB scheduling priority identification module 202, configured to determine an interfered resource block RB (Resource Block) and an undisturbed resource block RB for each user equipment according to the channel quality of the channel sounding reference SRS signal;

[0074] The resource block RB sorting module 203 is configured to perform scheduling priority sorting on the interfered resource block RB and the undisturbed resource block RB, wherein the priority of the undisturbed resource block RB is higher than that of the interfered resource block RB Level, the scheduling priority of the interfered resource block RB is related to the RB interference intensity, and the RB interference intens...

Abstract

The invention discloses a method based on SRS differential scheduling. The method comprises the following steps: receiving full-bandwidth channel detection reference SRS signals sent by a plurality of pieces of user equipment; according to the channel quality of the channel detection reference SRS signal, determining interfered and uninterfered resource blocks RB of each user equipment; carrying out the scheduling priority ranking on the interfered and non-interfered resource blocks RB, wherein the priority of the non-interfered resource blocks RB is higher than that of the interfered resource blocks RB, and the scheduling priority of the interfered resource blocks RB is related to the interference intensity of the RB; according to the priorities of the plurality of user equipment and the scheduling priority sequence of the resource blocks RB corresponding to the plurality of user equipment, enabling the user equipment with high priority to perform resource block RB scheduling, and enabling the user equipment with low priority to perform resource block RB scheduling; and enabling each piece of user equipment to schedule one or more resource blocks RBs with the highest priority in the scheduling priority sequence of the corresponding resource blocks RBs. The invention also discloses a device, a base station and a computer readable storage medium.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a method and system for differential scheduling based on SRS. Background technique [0002] NR (New Radio), also known as new air interface, is mainly used in the 5G field and is called 5G NR. 5G is a global 5G standard based on a new air interface design based on OFDM, and it is also a very important foundation for the next generation of cellular mobile technology. With the adoption of this standard by 3GPP, the term NR has been used and has become another synonym for 5G. In the 5G era, NR and the core network have independently evolved to 5G. The 5G indicators that people pay attention to mainly include data rate, delay and energy consumption cost. To achieve the demanding requirements, three key technologies are mainly used: ultra-dense heterogeneous network, mmWave communication, and massive MIMO. The NR system has been gradually perfected and constructe...
