Embodiment 1

[0154] The embodiment of the present invention provides a frequency backoff method based on an NR system, which is applied to a network side device. like image 3 As shown, the method includes:

[0155] Step 301, determine the target BWP;

[0156] The network-side device performs spectrum sensing during the sensing period, and detects that when the spectrum resources occupied by unauthorized users are applied for by authorized users, it determines that the conflict between the spectrum resources of the unauthorized user and the authorized user is detected, and the available part of the bandwidth that the conflict of spectrum resources has never been detected. In the BWP collection, determine the available target BWPs.

[0157] Step 302: Send a BWP handover instruction carrying the target BWP to an unauthorized user, so as to instruct the unauthorized user to perform BWP handover based on the target BWP.

[0158] In the NR system, in order to quickly and dynamically adjust t...

Embodiment approach

[0213] As an optional embodiment, the method also includes:

[0214] When it is determined that the available BWP set is empty according to the notification from the network side, it is selected to negotiate with the serving base station or other service equipment for interference avoidance.

[0215] As an optional implementation manner, receiving the BWP handover instruction sent by the network side, and determining the target BWP for handover according to the BWP handover instruction, including:

[0216] Receive an RRC reconfiguration message sent by the network side, and determine the handover target BWP according to the RRC reconfiguration message; or

[0217] Receive the downlink control information DCI format indication issued by the network side, and determine the handover target BWP according to the DCI format indication.

[0218] As an optional implementation manner, determining the target BWP for handover according to the RRC reconfiguration message includes:

Embodiment 3

[0239] A frequency backoff method based on an NR system in the present invention is described above, and a frequency backoff device based on an NR system is described below.

[0240] Figure 8 A schematic structural diagram of a frequency backoff device based on an NR system provided by an embodiment of the present invention, the device includes:

[0241] a target BWP switching module 801, configured to determine a target BWP;

[0242] The BWP handover instruction module 802 is configured to send a BWP handover instruction carrying the target BWP to an unauthorized user, so as to instruct the unauthorized user to perform BWP handover based on the target BWP.

[0243] As an optional implementation manner, the target BWP switching module determines the target BWP, including:

[0244] It is detected that the unlicensed user and the authorized user have conflicting spectrum resources;

[0245] An available target BWP is determined from the set of available partial bandwidth BWP...

Abstract

The invention discloses a frequency point concession method, device and equipment based on an NR system. The method comprises the following steps: determining a target BWP; and sending a BWP switching instruction carrying the target BWP to an unauthorized user so as to indicate the unauthorized user to perform BWP switching based on the target BWP. According to the invention, when the spectrum resources conflict, the base station side does not need to carry out frequency point concession, so that key parameters such as a cell center frequency point and a cell bandwidth do not need to be modified, the complexity of realizing frequency point concession is reduced, and the time delay is reduced; for the affected user, continuous communication of the user can still be ensured, and service interruption is not needed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method, device and device for frequency backoff based on an NR system. Background technique [0002] In hybrid networking scenarios, such as NR (New Radio, New Radio) and LTE (Long Term Evolution, Long Term Evolution) hybrid networking, NR and dedicated system hybrid networking, etc., it is usually necessary to use dynamic spectrum sharing or spectrum sensing technology . [0003] The goal of dynamic spectrum sharing or spectrum sensing is to detect spectrum opportunities and the spectrum usage of the network. The network needs to ensure that users with high priority are served first, and also ensure that spectrum resources are not monopolized by some users, that is, the network needs to be fair and Efficiently manage idle spectrum resources. When the network perceives that a certain segment of spectrum resources is not occupied by high-priority sy...
