Technical Field

Background

In a mobile communication system, a network device configures a radio link monitoring (Radio Link Monitoring, RLM) procedure of a terminal for monitoring a radio link signal, and the monitoring signal in the RLM procedure may include: a synchronization Signal block (Synchronous Signal Block, SSB) and/or a channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS). The physical layer of the terminal provides the radio link control (Radio Resource Control, RRC) layer with indication information of the physical layer link state, such as physical layer link state for indicating a Primary Cell (PCell) or a Primary secondary Cell (Primary Secondary Cell, PSCell). Wherein the indication information indicates "synchronization (in-sync)" when the channel quality is good and indicates "out-of-sync" when the channel quality is poor. And after the terminal continuously receives the preset number of out-of-step instructions, the terminal starts a timer. And stopping the running timer after the terminal continuously receives the preset number of synchronization instructions. If the timer is overtime, the problem of the wireless link monitored by the terminal is determined.

Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), and the terminal 11 may be a terminal-side Device such as a mobile phone, a tablet (Tablet PersonalComputer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, which is not limited to a specific type of the terminal 11 in the embodiment of the present invention. The network device 12 may be a base station or a core network, where the base station may be a 5G or later version base station (e.g., a gNB, a 5G NR NB, etc.), or a base station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), where the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present invention, only the base station in the NR system is exemplified, but not limited to the specific type of the base station.

The base stations may communicate with the terminal 11 under the control of a base station controller, which may be part of the core network or some base stations in various examples. Some base stations may communicate control information or user data with the core network over a backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly over a backhaul link, which may be a wired or wireless communication link. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multicarrier transmitter may transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multicarrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective corresponding coverage area. The coverage area of an access point may be partitioned into sectors that form only a portion of that coverage area. A wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). The base station may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations, including coverage areas of the same or different types of base stations, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks, may overlap.

The communication link in the wireless communication system may include an Uplink for carrying Uplink (UL) transmissions (e.g., from the terminal 11 to the network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from the network device 12 to the terminal 11). UL transmissions may also be referred to as reverse link transmissions, while DL transmissions may also be referred to as forward link transmissions.

As shown in fig. 2, an embodiment of the present invention provides a radio link monitoring method, which includes the following steps:

step 21: and respectively carrying out respective Radio Link Monitoring (RLM) processes according to at least two monitoring signal groups corresponding to the first frequency domain resource to obtain corresponding monitoring indication information, wherein the first frequency domain resource is as follows: a first cell group, a first cell or a first bandwidth part BWP.

Wherein the first cell group may be a primary cell group (Master Cell Group, MCG) or a secondary cell group (Secondary Cell Group, SCG), the first cell may be a PCell or a PSCell, and the first Bandwidth Part (BWP) may be an initial BWP, a current BWP, a default BWP, or the like. The network device may configure multiple monitoring signal groups (or RLM monitoring signal groups) for the same frequency domain resource, and one monitoring signal group may include at least one monitoring signal.

Under the condition that the network equipment configures a plurality of monitoring signal groups for the same frequency domain resource, the terminal respectively carries out a respective RLM process according to each monitoring signal group so as to obtain respective monitoring indication information (or referred to as "in-sync" or "out-of-sync" indication information). The monitoring parameters of the RLM process corresponding to each of the plurality of monitoring signal groups may be the same or different. Monitoring parameters includes, but is not limited to, RLM process failure conditions. For example, the network device configures two sets of monitoring signals, such as RLM RS(s) 1 and RLM RS(s) 2, for a certain frequency domain resource. Wherein different monitoring signal groups perform respective RLM processes, and may obtain different monitoring indication information.

Step 22: and determining whether the radio link failure occurs according to the monitoring indication information.

And comprehensively referencing the monitoring indication information of at least two monitoring signal groups to determine whether radio link failure occurs on the first frequency domain resource so as to determine the channel quality and the channel state of the first frequency domain resource.

Wherein, step 21 includes: and carrying out independent RLM measurement according to each monitoring signal group to obtain corresponding 'in-sync' indication information or 'out-of-sync' indication information. When the terminal performs an RLM process according to the monitoring signal group, the terminal generates 'in-sync' indication information when the channel quality is good, and generates 'out-of-sync' indication information when the channel quality is poor. For example, the network device configures two sets of monitoring signals for the terminal, such as RLM RS(s) 1 and RLM RS(s) 2. Wherein, the terminal performs independent RLM process for RLM RS(s) 1 to generate corresponding "in-sync" indication information or "out-of-sync" indication information. The terminal also performs an independent RLM procedure for RLM RS(s) 2 and generates corresponding "in-sync" indication information or "out-of-sync" indication information.

Wherein step 22 comprises: triggering respective timers and/or counters of the RLM process according to the monitoring indication information; determining that RLM process failure occurs when the timer times out and/or the counter reaches a threshold; and determining whether the radio link failure occurs according to the failure condition of the RLM process.

Wherein, different RLM processes may correspond to the same or different RLM process failure conditions, and in the embodiment of the present invention, the RLM process failure conditions include: the timer corresponding to the RLM procedure times out and/or the counter reaches a threshold value. Specifically, the step of triggering the respective timer and/or counter of the RLM procedure according to the monitoring indication information comprises: when the number of times of continuously generating the monitoring indication information of the indication "out-of-sync" reaches a preset threshold (e.g., N310), the terminal starts a timer (e.g., T310) and/or a counter corresponding to the corresponding RLM procedure. For example, the terminal performs an independent RLM procedure on the RLM RS(s) 1, and continuously generates "out-of-sync" indication information for the number of times reaching the first threshold, and then starts the timer 1 and/or the counter 1 corresponding to the RLM procedure. The terminal performs an independent RLM procedure for the RLM RS(s) 2, and continuously generates "out-of-sync" indication information for the number of times reaching a second threshold, and then starts the timer 2 and/or the counter 2 corresponding to the RLM procedure.

Accordingly, when the timer expires and/or the counter reaches a threshold, the step of determining that an RLM procedure failure has occurred comprises: if the number of times of the monitoring indication information which indicates "in-sync" generated by the RLM process reaches a preset threshold (such as N311) during the timer timing period and/or the counter counting period, the terminal stops the timer and/or the counter; otherwise, the timer keeps counting and/or the counter keeps counting, and when the timer times out and/or the counter reaches a threshold value, the RLM process failure is determined to occur. For example, for the RLM procedure of RLM RS(s) 1, the terminal starts timer 1 and/or counter 1, and if during the timing of timer 1 and/or the timing of counter 1, the terminal continuously generates "in-sync" indication information in the RLM procedure of RLM RS(s) 1 to reach the third threshold, the terminal stops timer 1 and/or counter 1; otherwise, the timer 1 keeps counting and/or the counter 1 keeps counting, and when the timer 1 times out and/or the counter 1 reaches a threshold value, the RLM process failure is determined to occur. For the RLM procedure of the RLM RS(s) 2, the terminal starts the timer 2 and/or the counter 2, and if the terminal continuously generates the "in-sync" indication information to reach the fourth threshold value in the RLM procedure of the RLM RS(s) 2 during the timing period of the timer 2 and/or the timing period of the counter 2, the terminal stops the timer 2 and/or the counter 2; otherwise, the timer 2 keeps counting and/or the counter 2 keeps counting, and when the timer 2 times out and/or the counter 2 reaches a threshold value, it is determined that the RLM process failure occurs.

Further, depending on the case of RLM procedure failure, implementations of determining whether a radio link failure occurred include, but are not limited to, the following:

in one mode, in the case of RLM procedure failure, a radio link failure is determined.

The terminal performs independent RLM procedures for different monitoring signal groups, and when the terminal determines that the RLM procedure fails in the RLM procedure for a certain monitoring signal group, it can directly determine that a radio link failure occurs. That is, in this manner, the network device determines that the radio link failure occurs as long as the RLM procedure of one monitoring signal group fails in at least two monitoring signal groups configured for the terminal.

And secondly, determining whether the radio link failure occurs according to the condition of the failure of the appointed RLM process in the RLM process.

Wherein, the specific RLM may be configured by a network device and agreed by a protocol, and the specific implementation manner of the second mode includes:

implementation 2-1, determining a radio link failure in case of failure of a specified RLM procedure. For example, the network device configures two monitoring signal groups RLM RS(s) 1 and RLM RS(s) 2 for the terminal, designates the RLM process as the RLM process corresponding to RLM RS(s) 1, and if the terminal fails the RLM process for RLM RS(s) 1, the terminal determines that the radio link fails; if the terminal fails the RLM procedure for RLM RS(s) 2, the terminal determines that no radio link failure occurs, and reports indication information of RLM procedure failure of RLM RS(s) 2.

Implementation 2-2, reporting indication information of RLM procedure failure of the specified RLM procedure in case of failure of the specified RLM procedure. For example, the network device configures two monitoring signal groups RLM RS(s) 1 and RLM RS(s) 2 for the terminal, designates the RLM process as the RLM process corresponding to RLM RS(s) 1, if the terminal fails the RLM process for RLM RS(s) 1, the terminal determines that no radio link failure occurs, and reports the indication information of the RLM process failure of RLM RS(s) 1.

And thirdly, the terminal determines whether the radio link failure occurs according to the number of the RLM process failures.

The terminal executes independent RLM processes for different monitoring signal groups, and when the terminal determines that the RLM process fails in the RLM processes for certain monitoring signal groups, the terminal does not determine that the radio link failure occurs according to the RLM process failure, but further determines whether the radio link failure occurs according to the number of the RLM process failures.

Implementations of determining whether a radio link failure occurs according to the number of RLM failures include, but are not limited to, one of the following:

in implementation 3-1, when the number of RLM procedure failures is equal to the number of RLM procedures, it is determined that a radio link failure occurs. If the number of RLM process failures is equal to the number of RLM process, the number of RLM process is the number of monitoring signal groups configured by the network device for the terminal, and in this case, all RLM processes of the monitoring signal groups fail, and then the terminal determines that radio link failure occurs.

Implementation 3-2, reporting indication information of RLM failure if the number of RLM process failures is smaller than the number of RLM processes (RLM Failure Report). If the number of RLM process failures is smaller than the number of RLM processes, in this case, not all RLM processes of the monitoring signal group fail, in this case, the terminal may directly determine that no radio link failure occurs, and report indication information of RLM process failure. For example, the network device configures two monitoring signal groups RLM RS(s) 1 and RLM RS(s) 2 for the terminal, the terminal only fails the RLM procedure for RLM RS(s) 1, and the terminal determines that no radio link failure occurs and reports indication information of the RLM procedure failure for RLM RS(s) 1. The indication information of RLM failure may be reported to a higher layer by the terminal, or may be reported to the network device by the terminal.

Further, the terminal further judges whether the monitoring signal group with the RLM process failure corresponds to the reference signal reporting the indication information of the RLM process failure, and determines whether the radio link failure occurs according to the judging result. Specifically, if the number of RLM process failures is smaller than the number of RLM processes, if it is determined that the monitoring signal group in which RLM process failures occur does not correspond to the reference signal for reporting the indication information of RLM process failures, it is determined that no radio link failure occurs and the indication information of RLM process failures is reported. For example, the network device configures two monitoring signal groups RLM RS(s) 1 and RLM RS(s) 2 for the terminal, where RLM RS(s) 2 is a reference signal corresponding to RLM procedure failure indication information reported by the terminal, and the terminal only makes RLM procedure failure for RLM RS(s) 1 in the RLM procedure for the two monitoring signal groups, and at this time, the terminal determines that no radio link failure has occurred and reports the indication information of RLM procedure failure.

And 3-3, determining that the radio link failure occurs under the condition that the number of the RLM process failures is smaller than that of the RLM process. If the number of RLM process failures is smaller than the number of RLM processes, in this case, not all RLM processes of the monitoring signal group fail, and in this case, the terminal may directly determine that a radio link failure occurs. For example, the network device configures two monitoring signal groups RLM RS(s) 1 and RLM RS(s) 2 for the terminal, the terminal fails the RLM procedure only for RLM RS(s) 1, and the terminal determines that the radio link failure occurs.

Further, in this case, the terminal may further determine whether the monitoring signal group in which the RLM procedure failure occurs corresponds to a reference signal reporting the indication information of the RLM procedure failure, and determine whether the radio link failure occurs according to the determination result. Specifically, if the number of RLM process failures is smaller than the number of RLM process failures, if it is determined that the set of monitoring signals in which RLM process failures occur corresponds to the reference signal reporting the indication information of RLM process failures, it is determined that radio link failures occur. For example, the network device configures two monitoring signal groups RLM RS(s) 1 and RLM RS(s) 2 for the terminal, where RLM RS(s) 2 is a reference signal corresponding to RLM procedure failure indication information reported by the terminal, and the terminal only fails RLM procedure for RLM RS(s) 2 when RLM procedure is performed for the two monitoring signal groups, and then the terminal determines that radio link failure occurs.

The above describes how to determine whether a radio link failure has occurred based on at least two monitoring signal groups when the network device has configured the terminal with these monitoring signal groups. The following description will further explain the processing method of the terminal in the case of determining that the radio link failure occurs.

Wherein, after step 22, the method further comprises: and triggering a radio link reestablishment process or reporting indication information of the failure of the RLM process under the condition of radio link failure. And triggering a radio link reestablishment process to recover connection to avoid data loss when the PCell fails in the radio link. And triggering reporting of indication information of the failure of the RLM process when the radio link failure occurs to the PScell, namely triggering reporting of the SCG failure.

In the embodiment of the present invention, the indication information of the RLM process failure includes at least one of the following information:

logical channel identification information corresponding to failure of the RLM procedure, such as logical channel 1;

bearer identification information corresponding to failure of the RLM procedure, such as data radio bearer (Data Radio Bearer, DRB) 1, signaling radio bearer (Signaling Radio Bearer, SRB) 1;

identification information of a monitoring signal group corresponding to failure of the RLM process, such as RLM RS(s) 1;

Signal type information contained in the monitoring signal group corresponding to the failure of the RLM process, such as a synchronization signal block SSB and/or a channel state indication reference signal CSI-RS;

signal identification information, such as SSB1, contained in the monitoring signal group corresponding to failure of the RLM process;

Wherein at least two monitoring signal groups mentioned in the embodiments of the present invention are configured or predefined by the network device. For example, the network device configuration or protocol specifies a set of monitoring signals for a plurality of RLMs corresponding to 1 cell (e.g., PCell) or 1 BWP of the terminal. Further, the monitoring signal group comprises at least one monitoring signal, and the monitoring signal comprises SSB and/or CSI-RS and the like.

When the network equipment configures a plurality of monitoring signal groups for the same frequency domain resource, the embodiment of the invention can adopt the independent RLM process to monitor the signals of different monitoring signal groups to obtain corresponding monitoring indication information, can accurately judge whether the radio link failure occurs according to the monitoring indication information of the plurality of RLM processes, and can carry out corresponding processing after the failure occurs so as to reduce the loss of data.
