detailed description

To make the objectives, technical solutions, and advantages of the disclosure more clear, the disclosure will be described in detail in conjunction with the drawings and specific embodiments below.

In the description of some embodiments of the present disclosure, first, some concepts used in the following description are explained.

Dual connectivity is a technology introduced in Long Term Evolution (LTE) and will also be used in New Radio (NR). It means that the UE can be connected to two base stations at the same time, and the two base stations provide data transmission and reception services for the UE at the same time. Since the radio resources of two base stations can be used at the same time, the service data transmission rate of the UE is doubled.

There is a signaling interface between two base stations serving the same UE, which can communicate configuration information of related UEs.

The serving base station of a dual-connected UE can belong to the same access network standard (Radio Access Technology (RAT)), for example: two LTE eNBs, or two NR gNBs; it can also belong to different RATs, for example: one LTE eNB, an NRgNB. The present disclosure can be applied to any type of dual-connected base station, and the type of the dual-connected base station is not limited.

Among the serving base stations of the dual-connected UE, one is a master base station (Master Node, MN) and one is a secondary base station (Secondary Node, SN). Among them, each base station can support carrier aggregation (Carrier Aggregation, CA) technology. The network will configure two special cells for dual-connected UEs, that is, configure one serving cell of MN as the primary serving cell of the UE (Primary Cell, PCell), and configure one serving cell of SN as the primary and secondary serving cell (Primary) Cell, PSCell). The other cells serving the UE of the MN and the SN are the secondary serving cells (Secondary Cell, SCell) of the UE.

Multi-connection refers to more than two base stations serving the same UE. The present disclosure is also applicable to multiple connections, and does not limit the types of multiple connection base stations.

Similar to dual connectivity, one of the serving base stations of a multi-connected UE is an MN or a master serving cell group (MCG), and the other is an SN or a secondary serving cell group (SCG). Among them, each base station can support CA.

The network will configure multiple special cells for multiple connected UEs, that is, one serving cell of the MN is configured as the PCell of the UE, and one PScell of each serving cell of each SN is configured. The other cells of the MN and SN serving the UE are the Scell of the UE.

In LTE and NR systems, the UE has a radio link monitoring (RadioLink Monitor, RLM) function. After determining that the radio link fails (RadioLink Failure, RLF), the UE performs the corresponding link recovery procedure. RLM and RLF are only implemented on PCell and PScell.

1. RLM and RLF on PCell

In the RLM function of LTE, the UE measures the signal-to-noise ratio (Signal to Interference Plus Noise, Ratio, SINR) of the cell reference signal (CRS) corresponding to the PCell physical downlink control channel (Physical Downlink Control CHannel, PDCCH). Realize monitoring of wireless links. When the physical layer (L1) of the UE measures that the SINR of the CRS corresponding to the PDCCH of PCell is below a certain threshold, it is determined that the wireless link is out of synchronization ("out-of-sync"); Out-of-sync indication, if the RRC layer has N310 consecutive out-of-sync indications, the UE RRC layer starts a timer (Timer) T310.

If the CRS corresponding to the measured PCell PDCCH is higher than a certain threshold, the wireless link synchronization ("in-sync") is deemed. The physical layer notifies the higher layer (RRC layer) of an in-sync indication. If the RRC layer has N311 consecutive in-sync indications, the UE stops the operation of Timer T310.

If the timer T310 runs out, the UE determines the RLF; and starts the timer T311. During the operation of the T311, the UE will try to find a suitable cell for RRC connection reestablishment. Before the reconstruction is successful, the transmission and reception of user plane data between the UE and the network will be interrupted.

If the UE is not successfully reestablished before T311 times out, the UE changes from the RRC connected state (RRC_CONNECTED) to the RRC idle state (RRC_IDLE).

The working process of T310 and T311 is shown in Figure 1.

The duration of N310, N311, T310 and T311 is configured by the network.

2. RLM and RLF on PSCell

In the LTE RLM function, the UE monitors the wireless link by measuring the SINR of the CRS corresponding to the PSCell and PDCCH. When the UE physical layer (L1) measures that the SINR of the CRS reference signal corresponding to the PDCCH of the PSCell is below a certain threshold, the radio link is considered "out-of-sync"; the physical layer notifies the higher layer (RRC layer, L3) of an out-of-sync of-sync indication, if the RRC layer has N313 consecutive out-of-sync indications, the UE RRC layer starts a Timer T313.

If the CRS reference signal corresponding to the measured PSCell PDCCH is higher than a certain threshold, the wireless link is deemed "in-sync". Then the physical layer notifies the higher layer (RRC layer) of an in-sync indication. If the RRC layer has N314 consecutive in-sync indications, the UE stops the operation of Timer T313.

If the timer T313 has timed out, the UE determines that the SCG radio link has failed (SCG-RLF); it stops sending and receiving data on the SN and reports the SCG-RLF to the network.

The duration of N313, N314 and T313 is configured by the network.

It should be noted that NR's RLM and RLF processing flow is similar to LTE. For example, the name of the counter / timer used may be different, and the type of measurement signal will be different. At present, 3GPP has agreed that the reference signal for RLM in NR is different from LTE, and will use the channel state information reference signal (Channel State Information-Reference Signal, CSI-RS) and / or synchronization signal block (Synchronization Signal Block, SSB) ) Do RLM for the reference signal. SSB and CSI-RS are two reference signals of NR.

Radio Resource Control (RRC) connection reestablishment

When there is a problem with the communication between the UE and the network, the UE needs to initiate the RRC connection reestablishment process. The RRC connection reestablishment process is used to restore the signaling connection between the network and the UE, that is, the signaling radio bearer one (SRB1).

Problems with communication between the UE and the network include the following:

A1. A wireless link failure occurs between the UE and the MN (for example: the UE detects that the downlink wireless link quality of the network is lower than the preset threshold; the UE MAC layer random access channel (Random Access Channel, RACH) attempts reach the maximum Unsuccessful; UE radio link control (Radio Link Control, RLC) layer AM mode retransmitted to the maximum number of times, etc.);

A2. The UE fails to switch;

A3. The UE finds that the signaling transmitted by SRB1 or SRB2 fails to protect the integrity;

A4. The UE finds that it cannot execute the RRC reconfiguration command sent by the network (for example, the value of the parameter after reconfiguration exceeds the hardware capability of the UE).

In view of the wireless link recovery method in the related art, the present disclosure has a problem that the wireless link recovery is slow, and provides an information sending method, a receiving method, a terminal, and a secondary base station.

As shown in FIG. 2, some embodiments of the present disclosure provide an information sending method, which is applied to a terminal and includes:

Step 201: Send link recovery auxiliary information to the secondary base station;

It should be noted that the link recovery auxiliary information includes: a radio link failure event of the primary serving cell (ie, PCell failure event) and / or measurement result information of at least one cell in the primary cell group where the failed link is located.

It should also be noted that when a wireless link fails between the terminal and the main base station (MN), the terminal cannot communicate with the MN, and can only communicate through the secondary base station (SN). Specifically, the link recovers auxiliary information The terminal is mainly sent to the secondary base station through a random access message during the random access process with the SN.

The following is a detailed description of some embodiments of the present disclosure from the perspective of different contents included in the link recovery auxiliary information.

1. The link recovery auxiliary information is a radio link failure event of the main serving cell

In this case, the terminal can use the following two methods to indicate the radio link failure event of the primary serving cell.

Method 1: Message 1 with random access (Msg1)

In this way, the specific implementation process of step 201 is:

Sending a first preamble to the secondary base station;

It should be noted that the first preamble is a dedicated preamble used in this embodiment, and the first preamble indicates a radio link failure event of the primary serving cell.

Further, the first preamble may be agreed by a protocol, or the first preamble may be configured by a network device. Specifically, the network device may be a secondary base station or a primary base station, that is, the first preamble may be The primary base station configures the terminal, or the secondary base station configures the terminal.

In this case, when the secondary base station receives the first preamble, the secondary base station can determine that the terminal is performing fast link recovery, and at this time, the secondary base station can make corresponding feedback, for example, to quickly reconfigure the terminal , Or the RRC connection is reestablished, or the RRC connection is restored, and the wireless link between the terminal and the primary base station is restored.

Method two: Message three with random access (Msg3)

In this way, the specific implementation process of step 201 is:

Send the first media access control layer control unit (MAC) to the secondary base station.

It should be noted that the first MAC CE is a newly added MAC used in this embodiment. The first MAC CE is used to indicate a radio link failure event of the primary serving cell, because the first MAC CE is Newly added, so it is necessary to add new logical channel identification information (ie, first logical channel identification information) to identify the first MAC, that is, the first MAC is identified by the first logical channel identification information.

It should be noted that in the non-contention random access process, the terminal can only use the first way to indicate the radio link failure event of the primary serving cell; in the contentious random access process, the terminal can only use the first way to perform the main The indication of the radio link failure event of the serving cell may also be performed by way two only to indicate the radio link failure event of the primary serving cell, or the terminal may use both modes one and two to simultaneously indicate the radio link failure event of the primary serving cell.

2. The link recovery auxiliary information is the measurement result information of at least one cell in the primary cell group where the failed link is located

In this way, the specific implementation process of step 201 is:

Send the second MAC to the secondary base station;

It should be noted that the second MAC is a newly added MAC used in this embodiment, and the second MAC carries the measurement result information of at least one cell in the primary cell group where the failed link is located; Since the second MAC is newly added, it is necessary to add one or extend the logical channel identification information in the related art (ie, the second logical channel identification information) to identify the second MAC, that is, the second MAC passes the Two logical channel identification information for identification.

Optionally, in this case, when a radio link failure between the terminal and the MN occurs, the second MAC may also be used to indicate a radio link failure event of the primary serving cell. Here, the second MAC is used for an implicit indication of the radio link failure event of the primary serving cell, that is, when the secondary base station receives the second MAC, it can know that a radio link failure has occurred between the terminal and the MN.

Specifically, the measurement result information of at least one cell in the primary cell group where the failed link is embodied in the second MAC CE includes one of the following ways:

A11. A list of cell identification information sorted according to cell measurement results;

A12. Whether the measurement result of the cell is higher or lower than the bitmap information of the first preset threshold;

For example, when the bitmap indicates 1 indicates that the measurement result of the cell corresponding to the bit is higher than the first preset threshold, otherwise, the measurement result indicating the cell corresponding to the bit is not higher than the first preset threshold. It should be noted that the first preset threshold value is defined by agreement, network device configuration, or terminal.

A13. Measurement result information of at least one cell;

For example, the measurement result information may be reference signal received power (RSRP) and / or reference signal received quality (RSRQ).

A14. Identification information of the cell whose measurement result is higher than the second preset threshold;

It should be noted that the second preset threshold value is defined by agreement, network device configuration, or terminal.

It should be noted that the above-mentioned second MAC CE and first MAC CE may be the same or different.

Several common ways of some embodiments of the present disclosure are exemplified as follows.

Case 1: When a link failure occurs between the terminal and the MN, and there is no link failure with the SN, in the random access process, the Msg1 indicates the radio link failure event of the primary serving cell through the first preamble;

Case 2: When the terminal fails to link with the MN, and there is no link failure with the SN, during the random access process, the primary preamble is used to indicate the radio link failure event of the primary serving cell in Msg1. The second MAC carries the measurement result information of at least one cell in the primary cell group where the failed link is located;

Case 3: When the terminal and the MN have a link failure and there is no link failure with the SN, in the random access process, the first MAC in the Msg3 CE indicates the radio link failure event of the primary serving cell;

Case 4. When the terminal and the MN have a link failure and there is no link failure with the SN, in the random access process, the first MAC in the Msg3 CE indicates the radio link failure event of the primary serving cell, through the Msg3 The second MAC carries the measurement result information of at least one cell in the primary cell group where the failed link is located;

Case 5. When the terminal fails the link with the MN and there is no link failure with the SN, in the random access process, the second MAC in Msg3 carries at least one cell in the primary cell group where the failed link is located At this time, the second MAC can be used to implicitly indicate the radio link failure event of the primary serving cell.

It should be noted that some embodiments of the present disclosure can be applied to 4G and subsequent evolution systems.
