Detailed Description

The protocol now does not combine wideband sub-segment (BWP) activation with cross-talk scheduling. When the user is affected or interfered by the frequency selection, the available resources in the current BWP do not meet the service requirement of the user, thereby affecting the user experience. In contrast, in the embodiment of the present application, BWP is combined with frequency selection scheduling, and the BWP is adjusted according to a sub-band Channel Quality Indicator (CQI) measured by a user with limited service, and the adjusted BWP is used to ensure that the user can use a better resource for transmission, while the user not affected by frequency selection still preferentially uses the original scheduling PRB.

Some associated explanations of some nouns are made below to better understand the embodiments of the present application.

In the fifth generation mobile communication system independent networking mode (5G-SA, Stand Alone), BWP includes information such as a Physical Resource Block (PRB) at a start position where Resource scheduling is possible and a maximum number of scheduled resources.

A sub-band Channel Quality Indicator (CQI) is also called a narrowband CQI, and refers to a terminal (UE) measuring multiple CQIs and an average CQI over the RBs. For example, the system bandwidth UE measures CQI (with multiple CQIs) in groups of every X RBs. Since the measurement bandwidth is small relative to the entire system bandwidth, the narrowband CQI can reflect the frequency-affected diversity over different bandwidths, and is also referred to as frequency selective CQI. Since the channel condition of only a part of the bandwidth is reflected, it is also called sub-band CQI.

The base station configures subband bandwidth, and when physical resources are divided into a plurality of subbands, each subband consists of the same number of PRBs, and the remaining PRBs may be insufficient from the last grouping, the remaining PRBs are used to form 1 subband.

Frequency selective fading (Frequency selective fading) refers to that fading characteristics are different in different Frequency bands. Frequency selective fading occurs when the frequency exceeds the coherence bandwidth. Frequency selective fading in the frequency domain is caused by the time delay spread of the channel in the time domain. The multipath effects cause flat fading, time selective fading and frequency selective fading, mainly frequency selective fading, of the transmission signal under different conditions.

The technical solution of the present application is further elaborated below with reference to the drawings and the embodiments.

In this embodiment, a network architecture is provided first, and fig. 1 is a schematic view of a composition structure of the network architecture in the embodiment of the present application, as shown in fig. 1, the network architecture includes two or more UEs 11 to 1N and a base station 31, where the UEs 11 to 1N interact with the base station 31 through a network 21.

The present embodiment proposes a resource scheduling method, which is applied to a resource scheduling device (e.g. a base station), and the functions implemented by the method may be implemented by a processor in the resource scheduling device calling a program code, where of course, the program code may be stored in a computer storage medium, and thus, the resource scheduling device at least includes the processor and the storage medium.

when the configured M BWPs can not meet the use of the UE, configuring and activating the BWP with the largest bandwidth and scheduling resources in the BWP;

and when the UE service requirement is reduced, the bandwidth of the BWP is reduced step by step.

Fig. 3 is a schematic flow chart of an implementation of a resource scheduling method according to an embodiment of the present application, and as shown in fig. 3, the method includes:

step S301, UE accesses network to trigger downlink service;

step S302, the base station determines that the current scheduling resource of the UE is the resource of continuous L PRBs from PRB-A to PRB-B of BWP-1;

step S303, when the wideband CQI reported by the UE is less than a threshold M, the base station configures all the resources of BWP-1 used by the UE in the downlink and configures sub-band CQI in BWP-1 reported by the UE;

step S304, when the sub-band CQI in BWP-1 is greater than the sub-band quantity of threshold A1 and the value of sub-band PRB is greater than L, the base station side starts the downlink frequency selection scheduling according to the sub-band CQI in BWP-1 reported by UE;

step S305, when the sub-band CQI in BWP-1 is greater than the sub-band quantity of threshold A1, the value of sub-band PRB is less than L, the base station selects new BWP-2 from the BWP group configured by RRC to activate through DCI;

step S306, the base station schedules the part of the resource of the UE not containing BWP-1 in BWP-2 (the BWP-2 resource contains BWP-1) and configures the sub-band CQI reported by the UE in BWP-2;

step S307, the UE reports the sub-band CQI, and the base station side starts downlink frequency selection scheduling according to the sub-band CQI in BWP-2 reported by the UE;

step S308, when the sub-band resource is in continuous state, the base station dispatches according to the maximum continuous block resource, otherwise, the frequency selection dispatching mode is kept;

step S309, when the sub-band CQI fed back by the UE in the BWP-2 resource is larger than the sub-band quantity of the threshold A1 and the value of the sub-band PRB is smaller than L, adjusting the BWP again, and the base station selects the BWP configuration with larger bandwidth to activate;

step S310, when the configured 4 BWPs can not meet the use of the UE, the base station adopts the BWP configuration with the largest bandwidth to activate and carry out resource scheduling therein;

in step S311, when the user service requirement in the system is reduced, the base station reduces BWP (PRB length reduction) step by step.

It can be seen from the above that, the base station performs frequency selective scheduling according to the reported sub-band CQI of some important users (for example, users with high user classes or priority classes), and when it is found that the frequency selective scheduling cannot meet the service requirement, the base station selects BWP with larger bandwidth configuration. When the BWP is updated and still cannot meet the demand, the BWP configuration is replaced again until the BWP with the largest bandwidth is used. When this portion of users no longer has a large traffic demand, the system is gradually tuned to a small bandwidth BWP. When the service requirement is reduced as a whole, the activated BWP is gradually reduced from large bandwidth to small bandwidth, and at the same time, it is ensured that the resource with better channel quality can be used by the user with low service requirement after the bandwidth is reduced.

Due to the adoption of the BWP configuration mode with consistent BWP center frequency points, namely the center frequency points of the configured BWPs are the same, and only the bandwidth is different, when the BWP is increased, a user adjusting the position of the scheduled resource can obtain better resources, and the better user in the original BWP can still use the resources in the originally scheduled frequency domain position in the new BWP without being influenced. Instead of avoiding interfering scheduling resources, scheduling is enhanced,

as can be seen from the above embodiments, the previous frequency selective scheduling needs to be changed after BWP is introduced in 5G, and the BWP bandwidth is expanded after frequency selective fading occurs with the focus on the frequency selective scheduling after BWP is introduced.

Compared with the related art, the embodiment of the application has the following technical advantages: BWP can be adjusted in a self-adaptive manner, and resources can be better scheduled by enhancing downlink frequency selection scheduling; when the service perception of the user is ensured, the original user is not influenced.
