Description

Configuration method, device, terminal, network side equipment and medium for mobility management

Technical Field

The present application belongs to the field of communications technologies, and in particular, to a configuration method, an apparatus, a terminal, a network side device, and a medium for mobility management.

Background

Currently, in the cell selection process, a terminal needs to measure a cell to be selected so as to perform channel quality evaluation and determine whether the cell meets a camping standard. 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/active (inactive) state, the UE needs to perform cell reselection continuously after cell selection in order to camp on a cell with higher priority or better channel quality.

In the related art, the measurement for mobility management needs to be subjected to layer three (L3) filtering. The specific process is roughly as follows: based on the reference signal, performing layer one (L1) filtering sampling, then reporting to L3, where L3 performs L3 filtering on the cell quality reported by the physical layer according to a Radio Resource Control (RRC) configuration parameter.

However, due to the above process, a certain cell reselection delay may be caused, and due to the existence of the delay, the idle/inactive terminal cannot timely reselect a target cell with better quality to camp on the target cell in the cell reselection process, so that the paging loss rate is increased, and the service quality is reduced.

Similarly, for a cell in an RRC connected state, a delay caused by layer three filtering in a cell handover procedure may increase a probability of handover failure, and further cause a decrease in service quality.

Detailed Description

The technical solutions in the embodiments of the present application will be described below clearly with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of protection of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in other sequences than those illustrated or otherwise described herein, and that the terms "first" and "second" are generally used herein in a generic sense to distinguish one element from another, and not necessarily from another element, such as a first element which may be one or more than one. In addition, "and/or" in the specification and the claims means at least one of connected objects, and a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

Technical terms related to the embodiments of the present application will be exemplified below.

1)SRS

Fifth Generation 5G (5 th Generation) mobile communication, SRS can be used for Beam management (Beam management), codebook (Codebook) based transmission, non-Codebook based transmission, antenna Switching (Antenna Switching) transmission, depending on the usage of SRS. The terminal can acquire a plurality of SRS resource sets (resource sets) through high-level signaling, and the configuration of each SRS resource set comprises the configuration of the usage, the periodic characteristics and the like.

It should be noted that both the SRS and the 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 the channel, the implementation details are very different:

1. the SRS supports a maximum of 4 antenna ports, and the CSI-RS supports a maximum of 32 antenna ports.

2. The SRS has low cubic metric, so that the power amplification efficiency of the terminal can be improved.

The SRS positions are in a comb-tooth (comb) structure, and the SRS may occupy 1, 2, and 4 consecutive OFDM symbols, but will be placed at the last 6 symbol positions of 14 symbols of a slot (slot). The SRS signals of different terminals are multiplexed in frequency domain at different comb offset (offset), for example, comb-2 configuration, so that multiplexing of two users can be realized.

The network may configure the terminal with periodic, semi-persistent, or aperiodic SRS. The SRS periodicity and other characteristics are all in units of SRS resource sets (resource sets), that is, all SRS attributes in one SRS set are the same. The SRS is used in various ways and some parameters are configured to control the behavior of the terminal to specifically transmit the SRS. All parameters related to the semi-continuous SRS are configured by high-level signaling (RRC), and after the activation of MAC CE signaling, the terminal starts to transmit according to the RRC configuration parameters after a specified time until the terminal receives a deactivation command of the base station; the related parameters of the aperiodic SRS are configured by RRC, a trigger command in DCI informs a terminal to send the SRS at a single time, 2bit in the DCI indicates the terminal to configure 3 SRS resource sets at most, and the other state indicates that the SRS resource sets are not activated. The RRC configuration parameters comprise time domain parameters such as SRS resource symbol positions, occupied symbol numbers, frequency hopping, repetition parameters R and the like.

Illustratively, the determination process for the Slot location:

for periodic and semi-persistent SRS, each SRS resource within an SRS resource set is configured with a periodic slot offset parameter for determining the period and slot offset of the SRS resource.

For aperiodic SRS, each SRS resource set is configured with a slot offset parameter, i.e. the SRS resources in the SRS resource set share a slot offset (may occupy different symbols). By receiving the receiving slot of the DCI triggering the aperiodic SRS resource set, and the subcarrier spacing of the DCI and the SRS and the slot offset of the SRS resource set, the slot position of the SRS resource set transmission can be determined.

2) Mobility management (mobility)

Mobility management is a necessary mechanism of a cellular mobile communication system, and can assist the system in realizing load balancing and improving user experience and overall performance of the system. Like LTE, mobility management in NR is of two types: mobility management in IDLE/INACTIVE state (e.g., mobility management for RRC-INACTIVE and RRC-IDLE states remain the same) and mobility management in connected state. Wherein:

aiming at the connection state, the method is mainly realized through cell switching, is completely controlled by a base station, and is assisted by a terminal for measurement.

For the IDLE state/active state, the method is mainly implemented by cell selection (applicable to RRC-IDLE state)/reselection (applicable to RRC-IDLE state and RRC-INACTIVE state), and is decided by the terminal, and the base station assists configuration.

Cell selection/reselection or cell handover requires the terminal to perform measurements, and measurements for mobility management and the like require operations such as L3 filtering. The specific process is roughly as follows: and performing L1 filtering sampling based on the reference signal, then reporting to L3, and performing L3 filtering (processing on a time domain to remove jitter Fn = (1-a) × Fn-1+ a + Mn) on the cell quality reported by the physical layer by the L3 according to the RRC configuration parameters.

However, the above procedure may bring a large delay, and due to the existence of the delay, the paging message may be lost, and the service quality may be degraded. In addition, for a connected UE, it may cause its handover failure.

In order to solve the above problem, in the configuration method, apparatus, terminal, network side device and medium for mobility management provided in this embodiment of the present application, the terminal may obtain first configuration information related to a target SRS (for uplink mobility management), and then transmit the target SRS based on the first configuration information to assist the network side device in performing terminal mobility measurement, and help the terminal perform fast cell reselection or cell handover, so as to reduce a time delay of cell reselection or handover, and improve communication performance.

It is noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE)/LTE Evolution (LTE-Advanced) systems, but may also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal Frequency Division Multiple Access (OFDMA), single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described techniques can be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for purposes of example, and NR terminology is used in much of the description below, but the techniques may also be applied to applications other than NR system applications, such as 6th generation,6g communication systems.
