CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202110476831.6 filed in China on Apr. 29, 2021, the entire contents of which are hereby incorporated by reference.

technical field

The present application belongs to the field of communication technologies, and specifically relates to a configuration method, apparatus, terminal, network side device and medium for mobility management.

Background technique

At present, in the process of cell selection, the terminal needs to measure the cell to be selected, so as to evaluate the channel quality and determine whether it meets the standard of camping. When the channel quality and signal strength of a certain cell satisfy the S criterion (measurement criterion for cell selection), it may be selected as a camping cell. In addition, when the terminal is in an idle/inactive state, the UE needs to continuously perform cell reselection after cell selection, so as to camp on a cell with a higher priority or better channel quality.

In the related art, measurements used for mobility management need to go through layer three (L3) filtering. The specific process is roughly as follows: Layer 1 (L1) filtering sampling is performed based on the reference signal, and then reported to L3, and L3 performs L3 filtering on the cell quality reported by the physical layer according to the radio resource control (Radio Resource Control, RRC) configuration parameters.

However, because the above process will bring a certain delay in cell reselection, due to the existence of the delay, the idle/inactive terminal cannot reselect a target cell with better quality in time during the process of cell reselection. Parking is performed, resulting in an increase in the paging loss rate, which in turn leads to a decrease in the quality of service.

Similarly, for a cell in the RRC connected state, the delay caused by the Layer 3 filtering process in the cell handover process will lead to an increase in the probability of handover failure, which in turn leads to a decrease in service quality.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the protection scope of this application.

The terms "first", "second" and the like in the description and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It is to be understood that the terms so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and that "first", "second" distinguishes Usually it is a class, and the number of objects is not limited. For example, the first object may be one or multiple. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the associated objects are in an "or" relationship.

The following will illustrate the technical terms involved in the embodiments of the present application.

1) SRS

The fifth generation 5G (5th Generation) mobile communication, according to the different uses of SRS, SRS can be used for beam management (Beam management), codebook-based transmission, non-codebook-based non-Codebook transmission, antenna switching (Antenna switching) Switching) to send. The terminal can obtain multiple SRS resource sets (resource sets) through high-layer signaling, and the configuration of each SRS resource set includes its purpose, periodic characteristics and other configurations.

It should be noted that both SRS and CSI-RS can be used as a reference for Quasi Co-location (QCL), that is, the network can configure other physical channels and SRS or CSI-RS quasi-co-location. Although both SRS and CSI-RS can be used for sounding channels, the specific implementation details are quite different:

1. SRS supports up to 4 antenna ports, while CSI-RS supports up to 32 antenna ports.

2. The SRS has a low cubic metric, which can improve the power amplifier efficiency of the terminal.

The SRS position is in a comb-shaped (comb) structure, and the SRS may occupy 1, 2, or 4 consecutive OFDM symbols, but will be placed in the last 6 symbol positions of the 14 symbols in a slot (slot). The SRS signals of different terminals are multiplexed on different comb offsets (offsets) in the frequency domain, for example, the comb-2 configuration can realize multiplexing of two users.

The network can configure periodic, semi-persistent or aperiodic SRS for the terminal. The SRS periodicity and other characteristics are all based on the SRS resource set (resource set), that is to say, all the SRS attributes in an SRS set are the same. There are various uses of the SRS, and the specific behavior of the terminal to send the SRS can be controlled by configuring some parameters. Among them, all parameters related to semi-persistent SRS are configured by high-level signaling (RRC). After activation by MAC CE signaling, the terminal starts to send according to the RRC configuration parameters after a specified time until the terminal receives the deactivation command from the base station; aperiodic SRS The relevant parameters are configured by RRC, and a command is triggered in the DCI to notify the terminal to send the SRS at a time. The 2 bits in the DCI instruct the terminal to configure at most 3 SRS resource sets, and the other state means inactive. The RRC configuration parameters include time domain parameters such as SRS resource symbol position, number of occupied symbols, frequency hopping, repetition parameter R, and the like.

Exemplary, for the determination process of the slot position:

For periodic and semi-persistent SRS, the SRS resource in each SRS resource set will be configured with a periodic slot offset parameter, which is used to determine the period and slot offset of the SRS resource. Through the configured period and slot offset , the position of the time slot for SRS transmission can be determined.

For aperiodic SRS, a slot offset parameter is configured in each SRS resource set, that is, the SRS resources in the SRS resource set share a slot offset (which can occupy different symbols). By receiving the receive time slot of the DCI that triggers the aperiodic SRS resource set, and the subcarrier spacing between the DCI and the SRS and the time slot offset of the SRS resource set, the location of the time slot sent by the SRS resource set can be determined.

2) Mobility management (mobility)

Mobility management is an essential mechanism for cellular mobile communication systems, which can assist the system to achieve load balancing, improve user experience and overall system performance. Like LTE, there are two types of mobility management scopes in NR: mobility management in idle state/inactive state (for example, mobility management in RRC-INACTIVE and RRC-IDLE state are consistent) and mobility in connected state manage. in:

For the connected state, it is mainly realized through cell handover, which is fully controlled by the base station and assisted by the terminal.

For idle state/active state, it is mainly realized through cell selection (applicable to RRC-IDLE state)/reselection (applicable to RRC-IDLE and RRC-INACTIVE state), and the terminal makes the decision and the base station assists the configuration.

Cell selection/reselection or cell handover all require measurement by the terminal, and measurement for mobility management and other purposes requires operations such as L3 filtering. The specific process is roughly as follows: perform L1 filtering and sampling based on the reference signal, and then report it to L3. L3 performs L3 filtering on the cell quality reported by the physical layer according to the RRC configuration parameters of L3 (processing in the time domain to remove the time jitter Fn) =(1−a)*Fn−1+a*Mn).

However, since the above process will bring a large delay, the existence of the delay will lead to the loss of paging messages and the deterioration of service quality. In addition, for the UE in the connected state, handover failure may also be caused.

In order to solve the above problem, in the mobility management configuration method, apparatus, terminal, network-side device, and medium provided by the embodiments of this application, the terminal can obtain the first configuration related to the target SRS (for uplink mobility management) by obtaining Then, based on the first configuration information, the target SRS is sent to assist the network side equipment to perform terminal mobility measurement and help the terminal to perform fast cell reselection or cell handover, thereby reducing the delay of cell reselection or handover and improving communication performance.
