Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.

Dual connectivity is a technology introduced in Long Term Evolution (LTE), and will also be used in New Radio (NR). The UE can be connected to two base stations at the same time, and the two base stations provide data transceiving services for the UE at the same time. Because the wireless resources of the two base stations can be used simultaneously, the service data transmission rate of the UE is improved by times.

Two base stations serving the same UE have signaling interfaces therebetween, which can communicate configuration information of related UEs.

The serving base stations of the dual-connectivity UE may belong to the same access network system (RAT), for example: two LTE enbs, or two NR gnbs; it may also belong to different RATs, for example: one LTE eNB, one NR gbb. The invention can be applied to double-connection base stations of any type combination, and the type of the double-connection base station is not limited.

One of the serving base stations of the dual-connectivity UE is a Master base station (Master Node, MN), and the other is a Secondary base station (Secondary Node, SN). Wherein each base station may support Carrier Aggregation (CA) technology. The network configures two special cells (special cells) for the dual-connection UE, that is, configures one serving Cell of the MN as a Primary serving Cell (PCell) of the UE, and configures a Primary serving Cell (PSCell) of one serving Cell of the SN. The other Cell of the MN and the SN serving the UE is a Secondary serving Cell (SCell) of the UE.

Multi-connection means that more than two base stations serve the same UE. The invention is also applicable to multi-connection, and the type of the multi-connection base station is not limited.

Similar to dual connectivity, one of the serving bss of the multi-connectivity UE is an MN or a Master Cell Group (MCG), and the other is an SN or a Secondary Cell Group (SCG). Wherein each base station may support CA.

The network configures a plurality of special cells (special cells) for the multi-connection UE, that is, configures one serving cell of the MN as a PCell of the UE, and configures a PScell of one serving cell of each SN. Other cells of the MN and SN serving the UE are scells of the UE.

In both LTE and NR systems, the UE has Radio Link Monitor (RLM) functionality. After determining Radio Link Failure (RLF), the UE performs a corresponding link recovery procedure. RLM and RLF are performed only on PCell and PScell.

1. RLM and RLF on PCell

In the RLM function of LTE, UE monitors a radio link by measuring a Signal to Interference plus Noise Ratio (SINR) of a Cell Reference Signal (CRS) corresponding to a Physical Downlink Control CHannel (PDCCH). When a UE physical layer (L1) measures that SINR of a CRS corresponding to a PDCCH of a PCell is lower than a certain threshold, the wireless link is determined to be out-of-synchronization ("out-of-sync"); the physical layer informs the higher layer (RRC layer, L3) of an out-of-sync indication, and if the RRC layer continues for N310 out-of-sync indications, the UE RRC layer starts a Timer (Timer) T310.

And if the CRS corresponding to the measured PCell PDCCH is higher than a certain threshold, the wireless link synchronization (in-sync) is determined. The physical layer informs the higher layer (RRC layer) of an in-sync indication and the UE stops the operation of Timer T310 if the RRC layer continues N311 in-sync indications.

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

If the UE is not successfully reestablished before T311 times out, the UE transitions from the RRC CONNECTED state (RRC _ CONNECTED) to the RRC IDLE state (RRC _ IDLE).

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

Where the durations of N310, N311, T310 and T311 are network configured.

2. RLM and RLF over PSCell

In the RLM function of LTE, UE monitors a radio link by measuring SINR of CRS corresponding to PSCell PDCCH. When a UE physical layer (L1) measures that the SINR of a CRS reference signal corresponding to a PDCCH of a PSCell is lower than a certain threshold, the wireless link is determined to be 'out-of-sync'; the physical layer informs the higher layer (RRC layer, L3) of an out-of-sync indication, and if the RRC layer continues for N313 out-of-sync indications, the UE RRC layer starts a Timer T313.

And if the measured CRS reference signal corresponding to the PSCell PDCCH is higher than a certain threshold, the wireless link is determined to be 'in-sync'. The physical layer informs a higher layer (RRC layer) of an in-sync indication, and the UE stops the operation of Timer T313 if the RRC layer continues for N314 in-sync indications.

If the timer T313 runs out of time, the UE judges that the SCG radio link fails (SCG-RLF); stopping data transceiving on the SN, and reporting the SCG-RLF to the network.

Wherein the duration of N313, N314, T313 is network configured.

It should be noted that, the RLM and RLF processing flow of NR is similar to that of LTE, such as: the names of the counters/timers used may differ and the type of measurement signal may differ. Currently, 3GPP has agreed that the Reference Signal for RLM in NR is different from LTE, and uses Channel State Information-Reference Signal (CSI-RS) and/or Synchronization Signal Block (SSB) as the Reference Signal for RLM. SSB and CSI-RS are NR two reference signals.

Radio Resource Control (RRC) connection re-establishment

When a problem occurs in the communication between the UE and the network, the UE needs to initiate an RRC connection reestablishment procedure. The RRC connection re-establishment procedure is used to restore the signaling connection between the network and the UE, i.e., signaling radio bearer one (SRB 1).

The communication problem between the UE and the network includes the following cases:

a1, radio Link failure occurs between UE and MN (for example, UE detects that the downlink Radio Link quality of a network is lower than a preset threshold, the number of times of Random Access Channel (RACH) attempts of UE MAC layer is not successful, the number of times of AM mode retransmission of UE Radio Link Control (RLC) layer is maximal, and the like);

a2, UE fails to switch;

a3, UE finds that the integrity protection of the signaling transmitted by SRB1 or SRB2 fails;

a4, the UE finds that the RRC reconfiguration instruction sent by the network cannot be executed (for example, the parameter value after reconfiguration exceeds the hardware capability of the UE).

The invention provides an information sending method, an information receiving method, a terminal and an auxiliary base station, aiming at the problem that the existing wireless link recovery mode has slow wireless link recovery.

As shown in fig. 2, an embodiment of the present invention provides an information sending method, which is applied to a terminal, and includes:

step 201, sending link recovery auxiliary information to an auxiliary base station;

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

It should be noted that, when a radio link failure occurs 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), and specifically, the link recovery auxiliary information is mainly sent to the secondary base station by a random access message during a random access process between the terminal and the SN.

The following describes embodiments of the present invention in detail from the perspective of recovering different contents included in the auxiliary information from the link.

1. The link recovery auxiliary information is a primary serving cell radio link failure event

In this case, the terminal may perform the indication of the primary serving cell radio link failure event in the following two ways.

Mode one, message one by random access (Msg 1)

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

sending a first lead code 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 the primary serving cell radio link failure event.

Further, the first preamble may be agreed by a protocol, or the first preamble may be configured by a network device, and specifically, the network device may be a secondary base station or a primary base station, that is, the first preamble may be configured by the primary base station for a terminal or configured by the secondary base station for the terminal.

In this case, when the secondary base station receives the first preamble, the secondary base station may determine that the terminal is performing fast link recovery, and at this time, the secondary base station may perform corresponding feedback, such as fast reconfiguration, or RRC connection reestablishment, or RRC connection recovery, on the terminal to recover the radio link between the terminal and the primary base station.

Mode two, message three (Msg 3) by random access

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

and transmitting a first media access control layer control element (MAC CE) to the secondary base station.

It should be noted that the first MAC CE is an added MAC CE used in this embodiment, where the first MAC CE is used to indicate a radio link failure event of the primary serving cell, and because the first MAC CE is added, a piece of logical channel identification information (i.e., first logical channel identification information) needs to be added to identify the first MAC CE, that is, the first MAC CE 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 mode to indicate the primary serving cell radio link failure event; in the contention random access process, the terminal may only use the first mode to indicate the primary serving cell radio link failure event, may also only use the second mode to indicate the primary serving cell radio link failure event, or may use both the first and second modes to indicate the primary serving cell radio link failure event.

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

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

sending the second MAC CE to the auxiliary base station;

it should be noted that the second MAC CE is a newly added MAC CE used in this embodiment, and the second MAC CE carries measurement result information of at least one cell in the primary cell group where the failed link is located; because the second MAC CE is newly added, it is necessary to add one or expand the existing logical channel identification information (i.e., the second logical channel identification information) to identify the second MAC CE, that is, the second MAC CE is identified by the second logical channel identification information.

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

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

a11, a list of cell identification information sorted according to the measurement results of the cells;

a12, whether the measuring result of the cell is higher than or lower than bit map (bitmap) information of a first preset threshold value or not;

for example, when the bitmap indicates that 1 represents that the measurement result of the cell corresponding to the bit is higher than the first preset threshold, otherwise, the measurement result of the cell representing the corresponding bit is not higher than the first preset threshold. It should be noted that the first preset threshold is defined by a protocol convention, a network device configuration, or a terminal.

A13, measuring 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 of which the measurement result is higher than a second preset threshold value;

it should be noted that the second preset threshold is defined by a protocol convention, a network device configuration, or a terminal.

The second MAC CE and the first MAC CE may be the same or different.

Several general ways of implementing the embodiments of the present invention are illustrated below.

In the first situation, when a link failure occurs between a terminal and an MN and no link failure occurs between the terminal and an SN, in the random access process, a wireless link failure event of a main service cell is indicated through a first lead code in an Msg 1;

in a second situation, when a link failure occurs between the terminal and the MN and no link failure occurs between the terminal and the SN, in the random access process, a wireless link failure event of a main service cell is indicated through a first lead code in the Msg1, and measurement result information of at least one cell in a main cell group where a failure link is located is carried through a second MAC CE in the Msg 3;

in a third situation, when the link failure occurs between the terminal and the MN and the link failure does not occur between the terminal and the SN, indicating a wireless link failure event of the main service cell through a first MAC CE in the Msg3 in the random access process;

in the random access process, when a link failure occurs between the terminal and the MN and no link failure occurs between the terminal and the SN, a first MAC CE in the Msg3 indicates a wireless link failure event of a main service cell, and a second MAC CE in the Msg3 carries measurement result information of at least one cell in a main cell group where a failed link is located;

and in a fifth case, when a link failure occurs between the terminal and the MN and no link failure occurs between the terminal and the SN, carrying measurement result information of at least one cell in a main cell group where the failed link is located by a second MAC CE in the Msg3 in a random access process, wherein at this time, the second MAC CE can be used for implicitly indicating a wireless link failure event of a main service cell.

It should be noted that the embodiment of the present invention may be applied to 4G and subsequent evolution systems.

In the embodiment of the invention, the terminal sends the link recovery auxiliary information to the auxiliary base station, and when the wireless link fails with the MN, the auxiliary network side completes the link recovery as fast as possible, so that the timeliness of network communication can be ensured.

Specifically, the first MAC CE is identified by first logical channel identification information.

Optionally, when the link recovery auxiliary information is measurement result information of at least one cell in a main cell group where the failed link is located, the link recovery auxiliary information sent by the receiving terminal includes:

receiving a second MAC CE sent by the terminal;

and the second MAC CE carries measurement result information of at least one cell in the main cell group where the failed link is located.

Further, the second MAC CE corresponds to second logical channel identification information.
