Description

Exception handling method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an exception handling method and a terminal.

Background

In a Long Term Evolution (LTE) system, each serving cell of a User equipment (UE, also called a terminal) is divided into a Timing Advance Group (TAG). The UE considers that the TA values of the serving cells of the same TAG are the same, and the TA values of the serving cells of different TAGs are different.

With the introduction of a Transmission Reception Point (TRP), a control panel (panel), and a beam (beam), a downlink cell may include a plurality of TRPs, one TRP may include a plurality of panels, and one panel may transmit a plurality of beams. Meanwhile, with the introduction of multiple panels of the UE, one uplink UE can simultaneously send multiple beams through multiple panels.

This makes the TA value between the multiple links (links) formed with the base station side may be different when multiple beams are transmitted simultaneously, i.e. as shown in fig. 1 and fig. 2, the TA values of link1 (shown by a dotted beam in the figure) and link2 (shown by a dashed-dotted beam in the figure) may be different in case of scenario 1 in fig. 1 or scenario 2 in fig. 2.

In a new air interface (NR) system, if scenario 1 and scenario 2 are both connected to one cell (cell) for the UE following the definition of TA and the transmission of TA commands by the current LTE system, the TA values of the two links are indistinguishable. In the NR system, a plurality of TA values are introduced for a plurality of beams, that is, each TA value corresponds to a link, and there is no processing method for link abnormality in the scene in the NR system, so that the communication reliability of the NR system cannot be guaranteed.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 3, an embodiment of the present invention provides an exception handling method, which is applied to a multi-beam scenario, where each transmit/receive beam pair corresponds to one link, each link corresponds to one timing advance TA value, and a timing advance timer TAT is set for the TA value, where the exception handling method includes:

step 301, when a link of a terminal is abnormal, determining an abnormal type;

it should be noted that, in the embodiments of the present invention, a link refers to a path formed by a transmit beam at a transmitting end passing through a spatial channel to a receive beam at a receiving end, and the link may also be referred to as a path. When a link of a terminal is abnormal (that is, the terminal cannot normally transmit and receive information using a certain link), the type of the abnormality needs to be determined first.

And 302, performing exception handling on the link according to the exception type.

After the abnormal type of the terminal is determined, the terminal executes the abnormal processing of the link corresponding to the abnormal type according to the abnormal type.

The exception handling method executed by the terminal is different according to the exception type, and the specific implementation of step 302 will be described in detail below in terms of different exception types.

Firstly, the abnormal type is the overtime of a timing advance timer TAT

In this case, the specific implementation of step 302 includes:

determining the type of the TAT, and performing exception handling corresponding to the type of the TAT according to the type of the TAT.

It should be noted that the types of TAT provided in this embodiment include: one TAT for one timing advance TA value and/or one TAT for multiple TA values.

Because the types of the TATs are different, the modes of the terminal performing exception handling corresponding to the types of the TATs are also different, and the specific processing procedures of the terminal are described below from the perspective of different types of the TATs, respectively.

1. When the TAT is of a type corresponding to a TA value and supporting a timeout of the TAT of the first link of the physical uplink control channel PUCCH, specifically, the specific processing procedure of the terminal includes the following steps:

clearing a buffer (buffer) of a hybrid automatic repeat request (HARQ) of the first link and a link which transmits information simultaneously with the first link;

notifying Radio Resource Control (RRC) to release the PUCCH of the first link through inter-layer signaling;

notifying, by inter-layer signaling, an RRC to release an uplink pilot signal (SRS) of the first link and an SRS of a link that transmits information simultaneously with the first link;

clearing the first link and downlink configuration information and uplink authorization information of a link which simultaneously transmits information with the first link;

determining an ongoing TAT timeout for a link transmitting information concurrently with the first link.

2. When the type of the TAT is that one TAT corresponds to one TA value and the TAT of the second link that does not support the PUCCH is overtime, specifically, the specific processing procedure of the terminal includes the following steps:

and informing the RRC to release the SRS of the second link through interlayer signaling.

3. When the type of the TAT is that one TAT corresponds to multiple TA values, and a link corresponding to the TAT that is overtime includes a third link supporting a PUCCH, specifically, the specific processing procedure of the terminal includes the following steps:

emptying the buffer of the HARQ of the link corresponding to the overtime TAT;

informing the RRC to release the PUCCH of the third link corresponding to the TAT overtime through interlayer signaling;

notifying the RRC to release the SRS of the link corresponding to the TAT through interlayer signaling;

clearing downlink configuration information and uplink authorization information of a link corresponding to the overtime TAT;

determining a running TAT timeout for a link transmitting information concurrently with the third link.

4. When the type of the TAT is that one TAT corresponds to multiple TA values, and a link corresponding to the TAT that is overtime does not include a link supporting a PUCCH, specifically, the specific processing procedure of the terminal includes the following steps:

and informing the RRC to release the SRS of the link corresponding to the TAT through interlayer signaling.

Secondly, the abnormal type is that the TA values of different links belonging to the simultaneous work of the terminal can not meet the minimum requirement of the terminal

In this case, the specific implementation of step 302 includes:

comparing the TA value of the link of the terminal with a preset value to obtain a comparison result, wherein the preset value comprises: a TA value or a preset fixed value of the reference link;

and performing exception handling of the link according to the comparison result.

It should be noted that, in this case, the terminal may select one link from its own links as a reference link, and compare the other links with the reference link; the terminal can also compare the TA values of all links with a fixed value; the method for processing the terminal exception is different according to different selection methods of the preset values, and the specific processing procedure of the terminal is described below from the perspective of the selection methods of different preset values.

1. When the preset value is a TA value of the reference link, specifically, the terminal performs exception handling by using one of the following manners:

if the difference value between the TA value of the link of the terminal and the TA value of the reference link is greater than or equal to a first preset difference threshold, deleting the link with the larger TA absolute value, and requesting the base station to recover the link with the larger TA absolute value;

if the difference value between the TA value of the link of the terminal and the TA value of the reference link is greater than or equal to a first preset difference threshold, deleting the link of which the signal quality is less than or equal to a preset value, and requesting the base station to recover the link of which the signal quality is less than or equal to the preset value;

if the difference between the TA value of the link of the terminal and the TA value of the reference link is greater than or equal to the first preset difference threshold, deleting the fourth link (it should be noted that the fourth link is a link randomly selected by the terminal), and requesting the base station to recover the fourth link;

if the difference value between the TA value of the link of the terminal and the TA value of the reference link is greater than or equal to a first preset difference threshold, deleting the link which does not support the PUCCH;

if the difference value between the TA value of the link of the terminal and the TA value of the reference link is greater than or equal to a first preset difference threshold, acquiring an exception handling mode of a network side, and carrying out exception handling according to the exception handling mode; it should be noted that, in this implementation, after the terminal determines that an exception occurs, the terminal itself does not determine any exception handling, but waits for the notification from the network side, and after obtaining how to perform exception handling from the notification from the network side, performs the exception handling.

In this case, all links are usually compared with the reference link before performing exception handling on the comparison result, and in this case, the deleted link may also be the reference link.

2. When the preset value is a TA value of the reference link, specifically, the terminal performs exception handling by using one of the following manners:

if the difference value between the TA value of the link of the terminal and the TA value of the reference link is greater than or equal to a second preset difference threshold, deleting the link of which the difference value is greater than or equal to the second preset difference threshold, and requesting the base station to recover the link of which the difference value is greater than or equal to the second preset difference threshold; or

And if the difference value between the TA value of the link of the terminal and the TA value of the reference link is greater than or equal to a second preset difference threshold, acquiring an exception handling mode of the network side, and carrying out exception handling according to the exception handling mode.

In this case, each link may perform exception handling after being compared with the reference link, and the terminal may not delete the reference link when deleting the link.

3. When the preset value is a preset fixed value, specifically, the terminal selects one of the following modes to perform exception handling:

if the difference value between the TA value of the link of the terminal and the preset fixed value is greater than or equal to a third preset difference threshold, deleting the link of which the difference value is greater than or equal to the third preset difference threshold, and requesting the base station to recover the link of which the difference value is greater than or equal to the third preset difference threshold; or

And if the difference value between the TA value of the link of the terminal and the preset fixed value is greater than or equal to a third preset difference threshold, acquiring an exception handling mode of the network side, and carrying out exception handling according to the exception handling mode.

In this embodiment, similar to embodiment 2 described above, the comparison may be performed one by one and then the processing may be performed one by one in a concrete implementation.
