BACKGROUND

A terminal device may need to execute two behaviors based on a configuration by a network side, which are referred to as a first behavior and a second behavior for convenience of description, wherein execution of the first behavior may cause a conflict with execution of the second behavior, for example, the execution of the first behavior causes the terminal device to perform resource switching and thus cannot execute the second behavior. In this case, it is not clear how the terminal device executes the two behaviors.

In order to facilitate understanding of the technical solutions of the implementations of the present disclosure, the technical solutions related to the implementations of the present disclosure will be explained below.

Measurement

In order to better achieve mobility switching of a terminal device, a network side may configure the terminal device to measure a Reference Signal Received Power (RSRP) or Reference Signal Received Quality (RSRQ) or a Signal to Interference plus Noise Ratio (SINR) of a reference signal of a target neighbor region of a same frequency, different frequencies, or different Radio Access Technologies (RATs) in a specific time window, wherein the specific time window refers to a measurement gap.

In New Radio (NR) Release 15 (Rel-15), in addition to less than 6 GHz, a millimeter wave frequency band above 6 Ghz is also introduced into a working frequency range of a terminal device. Therefore, according to whether the terminal device supports a capability of a Frequency Range 1 (FR1) or a Frequency Range 2 (FR2), a measurement gap for a UE (per UE) and a measurement gap for a FR (per FR) are defined in Radio Access Network 4 (RAN4), wherein the measurement gap per UE may also be referred to as gapUE, and the measurement gap per FR includes gapFR1 and gapFR2. At the same time, the terminal device also introduces capability indication information (i.e., independentGapConfig) of independent gap measurements in different frequency ranges, and the indication information is used for indicating whether the measurement gap per FR may be configured. Contents of the independentGapConfig may be seen in Table 1 below.

- gapFR1: a measurement gap configuration is only applicable to FR1, and gapFR1 and gapUE do not support simultaneous configuration. In addition, in an Evolved Universal Terrestrial Radio Access (E-UTRA)-NR Dual Connectivity (EN-DC) mode, gapFR1 does not support a configuration through an NR Radio Resource Control (RRC) signaling, and only an LTE RRC signaling may configure gapFR1.
- gapFR2: a measurement gap configuration is only applicable to FR2, and gapFR2 and gapUE do not support simultaneous configuration.
- gapUE: a measurement gap configuration is applicable to all frequency bands, specifically including FR1 and FR2. In the EN-DC mode, only the LTE RRC signaling may configure gapUE, and gapUE does not support a configuration through an NR RRC signaling. If gapUE is configured, gapFR1 or gapFR2 cannot be configured.

Capability of a Terminal Device

A capability of independent gap measurements in different frequency ranges (i.e., Per FR gap capability): if the terminal device supports the Per FR gap capability, it indicates that the terminal device supports an independent radio frequency or baseband design of FR1 and FR2, and has terminal behaviors such as an independently handling measurement and switching of related frequency bands or carriers of FR1 and FR2.

A high-speed rail Radio Resource Management (RRM) enhanced capability: the high-speed rail RRM enhanced capability includes a high-speed rail enhanced measurement capability, such as an LTE high-speed rail enhanced measurement capability and an NR high-speed rail enhanced measurement capability. If the terminal device supports the high-speed rail enhanced measurement capability, it indicates that the terminal device supports a high-speed rail enhanced measurement behavior. Indication information of the high-speed rail enhanced measurement capability is achieved through HighSpeedConfig, and contents of HighSpeedConfig are shown in Table 2 below.

Further, a network side may configure (or indicate) to the terminal device whether the network side supports perFRgap or high-speed rail enhanced measurement. The network side may also configure (or instruct) the terminal device to perform a high-priority measurement on some NR frequency points or LTE frequency points, and the high-priority measurement may be, for example, an Early Measurement (EM). The above configuration contents may be achieved through a System Information Block (SIB) message or an RRC signaling.

Measurement Type

Types of measurement include: an NR measurement, an LTE measurement (i.e. E-UTRA measurement), a Layer 3 (L3) mobility measurement, a positioning measurement, an interference cancellation measurement, an early measurement, and so on.

Types of measurement further include: a measurement for Radio Link Monitor (RLM), measurements for Beam Failure Detection (BFD) and Candidate Beam Detection (CBD) (e.g. L1 measurements).

Switching Behavior and Interruption

Types of switching behaviors are: Sounding Reference Signal (SRS) carrier switching, SRS port switching, antenna switching, antenna port switching, Band Width Part (BWP) switching, cell handover, and Multiple In Multiple Out (MIMO) layer switching.

Generally, a certain delay is needed when the above switching behavior occurs, and interruption of transmission (including uplink and downlink) or measurement may be brought for a period of time. It should be noted that implementations of the present disclosure collectively refer to “sending” and “receiving” as “transmitting”.

Particularly, in the EN-DC mode or an NR-E-UTRA Dual Connectivity (NE-DC) mode, the network side considers that since there is no real-time and efficient interaction between two Cell Groups (CGs), it is impossible to guarantee that a configuration of SRS carrier switching of one CG will not conflict with a measurement of the other CG. At the same time, the terminal device needs to spend extra time to coordinate an LTE modem and an NR modem, which makes it difficult to avoid an influence of that SRS carrier switching of one CG interrupts the measurement or data transmission of the other CG.

However, in Rel-15, RAN4 agreed that a Synchronization Signal Block (SSB) measurement takes precedence over uplink transmission. Similar to an LTE system, a measurement behavior based on an SSB or a Channel Status Indicator Reference Signal (CSI-RS) in an NR system takes precedence over an SRS carrier switching behavior of NR, that is, if there is a conflict between the two, the terminal device and the network side will suspend or interrupt SRS carrier switching first to execute the measurement behavior. However, for an impact of SRS carrier switching of an LTE side on an NR measurement or SRS carrier switching of an NR side on an LTE measurement, terminals, chips, and network manufacturers hold different views on how to standardize behaviors of a terminal device, and a unified solution still cannot be formed in standardization discussion. To this end, following technical solutions of the implementations of the present disclosure are proposed.

FIG. 2 is a schematic flowchart of a method for determining a behavior of a terminal device according to an implementation of the present disclosure. As shown in FIG. 2, the method for determining the behavior of the terminal device includes following acts.

In act 201, a terminal device determines that a first behavior and a second behavior are executed simultaneously; wherein the first behavior includes at least one of following: SRS carrier switching, SRS port switching, antenna switching, antenna port switching, BWP switching, cell handover, and MIMO layer switching; the second behavior includes at least one of following: a measurement behavior and a transmission behavior.

In an implementation of the present disclosure, the terminal device receives first configuration information and second configuration information sent by a network side, the first configuration information is used for the terminal device to execute the first behavior, and the second configuration information is used for the terminal device to execute the second behavior. The terminal device may determine whether the first behavior and the second behavior are configured to be executed simultaneously based on the first configuration information and the second configuration information. If the first behavior and the second behavior are configured to be executed simultaneously, since a capability of the terminal device cannot simultaneously execute the first behavior and the second behavior, it is considered that the first behavior and the second behavior conflict, for example, execution of the first behavior will cause a conflict to the second behavior (i.e., the second behavior cannot be normally executed).

In an example, the first behavior and the second behavior are executed simultaneously, which may mean that the first behavior and the second behavior are triggered simultaneously. In another example, the first behavior and the second behavior are executed simultaneously, which may mean that execution of the second behavior is triggered during a process in which the first behavior is being executed. Or, execution of the first behavior is triggered during a process in which the second behavior is being executed.

In an implementation of the present disclosure, the first behavior includes at least one of following: SRS carrier switching, SRS port switching, antenna switching, antenna port switching, BWP switching, cell handover, and MIMO layer switching.

In an implementation of the present disclosure, the second behavior includes at least one of following: a measurement behavior and a transmission behavior. Here, a type of measurement corresponding to the measurement behavior may refer to the foregoing related description. It should be noted that the transmission behavior includes an uplink transmission behavior and/or a downlink transmission behavior.

In act 202, the terminal device executes one of the first behavior and the second behavior.

In an implementation of the present disclosure, if the first behavior and the second behavior are executed simultaneously, execution of the first behavior will affect execution of the second behavior, that is, the first behavior and the second behavior conflict. The following describes how the terminal device executes the two behaviors in combination with different situations.

Situation One

The first behavior and the second behavior respectively correspond to different RATs; or, the first behavior and the second behavior correspond to a same RAT.

No matter what working mode the terminal device is in, 1) in an optional mode, the terminal device interrupts the first behavior and executes the second behavior; after the terminal device executes the second behavior, the first behavior is executed. Or, 2) in another optional mode, the terminal device abandons execution of the first behavior and executes the second behavior.

In an example, the first behavior is SRS carrier switching and the second behavior is a measurement behavior. No matter what working mode the terminal device is in, SRS carrier switching is stopped, and a measurement behavior is executed, and the SRS carrier switching is started after the measurement behavior is completed; or, SRS carrier switching triggered this time is abandoned and stopped, and a measurement behavior is executed.

In an example, RATs corresponding to the first behavior and the second behavior are both NR, according to the above solution, NR SRS carrier switching needs to be interrupted or abandoned, and the NR SRS carrier switching does not affect an NR measurement behavior (such as NR SSB measurement or NR CSI-RS measurement).

In an example, RATs corresponding to the first behavior and the second behavior are both LTE, according to the above solution, LTE SRS carrier switching needs to be interrupted or abandoned, and the LTE SRS carrier switching does not affect an LTE measurement behavior.

According to the above technical solution, stability of measurement is ensured and functions such as mobility management, beam management are preferentially ensured to be uninterrupted.

Situation Two

The first behavior and the second behavior respectively correspond to different RATs.

No matter what working mode the terminal device is in, 1) in an optional mode, the terminal device interrupts the second behavior and executes the first behavior; after the terminal device executes the first behavior, the second behavior is executed. Or, 2) in another optional mode, the terminal device abandons execution of the second behavior and executes the first behavior.

In an example, the first behavior is SRS carrier switching and the second behavior is a measurement behavior. No matter what working mode the terminal device is in, the measurement behavior is stopped, and SRS carrier switching is executed, and the measurement behavior is started after the SRS carrier switching is completed.

According to the above technical solution, priority of SRS carrier switching is ensured, so that uplink detection of different carriers or a requirement of uplink positioning may be completed more quickly, and performance loss of a general measurement which is not in a hurry may be controlled even if it is interrupted.

Situation Three

The terminal device determines to execute one of the first behavior and the second behavior according to a capability of the terminal device.

A1) In an optional mode, if the terminal device supports a capability of independent gap measurements in different frequency ranges, the terminal device interrupts the first behavior for NR FR2 and executes the second behavior for NR FR1. Further, optionally, the terminal device interrupts the second behavior for NR FR2.

In an example, the first behavior is SRS carrier switching and the second behavior is a measurement behavior. According to the above solution, SRS carrier switching of NR FR2 cannot affect a measurement behavior of NR FR1 or LTE. Optionally, an influence of interruption is allowed for a measurement behavior of NR FR2.

A2) In an optional mode, if the terminal device supports a capability of independent gap measurements in different frequency ranges, the terminal device interrupts the first behavior for NR FR1 and executes the second behavior for NR FR2. Further, optionally, the terminal device interrupts the second behavior for NR FR1.

In an example, the first behavior is SRS carrier switching and the second behavior is a measurement behavior. According to the above solution, SRS carrier switching of NR FR1 cannot affect a measurement of NR FR2, but an influence of interruption is allowed for measurements of NR FR1 and LTE.

B1) In an optional mode, if the terminal device does not support a capability of independent gap measurements in different frequency ranges, the terminal device interrupts the second behavior and executes the first behavior, or the terminal device interrupts the first behavior and executes the second behavior.

Here, the first behavior includes at least one of following: the first behavior for NR FR1, the first behavior for NR FR2; the second behavior includes at least one of following: the second behavior for NR FR1, and the second behavior for NR FR2.

In an example, the first behavior is SRS carrier switching and the second behavior is a measurement behavior. According to the above solution, one of following may be regarded as a behavior specified in a standard: 1. measurement behaviors can be all influenced by SRS carrier switching and interrupted; or, 2. all measurement behaviors cannot be influenced by SRS carrier switching and interrupted. Here, a measurement behavior is not limited to a measurement behavior of FR1 or FR2, and SRS carrier switching is not limited to SRS carrier switching of FR1 or FR2. That is to say, whether the measurement behavior of FR1 or FR2 or the SRS carrier switching of FR1 or FR2, it may be stipulated in the standard that measurement behaviors can be all influenced by SRS carrier switching and interrupted, or, all measurement behaviors cannot be influenced by SRS carrier switching and interrupted.

B2) In an optional mode, if the terminal device does not support a capability of independent gap measurements in different frequency ranges, the terminal device determines whether to interrupt the second behavior and execute the first behavior or interrupt the first behavior and execute the second behavior based on its own implementation.

In an example, the first behavior is SRS carrier switching and the second behavior is a measurement behavior. According to the above solution, a terminal may determine based on its own implementation: 1. measurement behaviors can be all influenced by SRS carrier switching and interrupted; or, 2. all measurement behaviors cannot be influenced by SRS carrier switching and interrupted.

It should be noted that in the above solution, the capability of independent gap measurements in different frequency ranges may also be called per FR gap capability.

According to the above technical solution, for a terminal device (which may be considered as well designed) supporting some measurement capabilities, stability of measurement is ensured, and functions such as mobility management and beam management are preferentially ensured to be uninterrupted. For a general terminal device, priority of SRS carrier switching is ensured, so that uplink detection of different carriers or a requirement of uplink positioning may be completed more quickly, and performance loss of a general measurement which is not in a hurry may be controlled even if it is interrupted.

Situation Four

The terminal device determines to execute one of the first behavior and the second behavior according to a configuration by a network side.

C1) In an optional mode, if the network side configures the terminal device to be in a dual connectivity mode, the terminal device interrupts the first behavior and executes the second behavior for a first RAT, wherein, in the dual connectivity mode, a RAT of a Master Node (MN) is the first RAT and a RAT of a Secondary Node (SN) is a second RAT.

1. In an optional mode, the dual connectivity mode is an EN-DC mode, correspondingly, the first RAT is LTE and the second RAT is NR; the terminal device interrupts the first behavior for LTE and the first behavior for NR, and executes the second behavior for an LTE frequency point.

In an example, if it is currently the EN-DC mode, it is considered that an LTE node is a network access anchor point (i.e., MN), so a measurement priority of an LTE side frequency point is high, and it is necessary to ensure that LTE idle state cell selection and reselection, or a connection state switching measurement, or the like are not affected by other behaviors, so neither LTE SRS carrier switching nor NR SRS carrier switching can cause an interruption influence on an LTE intra-RAT measurement or an NR inter-RAT measurement. It should be noted that a target frequency point of the LTE intra-RAT measurement or the NR inter-RAT measurement is an LTE frequency point.

2. In another optional mode, the dual connectivity mode is an NE-DC mode, correspondingly, the first RAT is NR and the second RAT is LTE; the terminal device interrupts the first behavior for LTE and the first behavior for NR, and executes the second behavior for an NR frequency point.

In an example, if it is currently an NE-DC mode, it is considered that an NR node is a network access anchor point (i.e., MN), so a measurement priority of an NR frequency point is high. Similarly, neither LTE SRS carrier switching nor NR SRS carrier switching can cause an interruption influence on an NR intra-RAT measurement or an LTE inter-RAT measurement. It should be noted that a target frequency point of the NR intra-RAT measurement or the LTE inter-RAT measurement is an NR frequency point.

C2) if the network side configures the terminal device to be in a dual connectivity mode, the terminal device interrupts the second behavior and executes the first behavior for a first RAT, wherein, in the dual connectivity mode, a RAT of a MN is the first RAT and a RAT of an SN is a second RAT.

1. In an optional mode, the dual connectivity mode is an EN-DC mode, correspondingly, the first RAT is LTE and the second RAT is NR; the terminal device interrupts the second behavior for LTE and the second behavior for NR, and executes the first behavior for an LTE frequency point.

2. In another optional mode, the dual connectivity mode is an NE-DC mode, correspondingly, the first RAT is NR and the second RAT is LTE; the terminal device interrupts the second behavior for LTE and the second behavior for NR, and executes the first behavior for an NR frequency point.

C3) if the network side configures the terminal device to be in a Stand Alone (SA) mode, the terminal device interrupts the first behavior and executes the second behavior for a first RAT; wherein a RAT of an access node in the SA mode is the first RAT.

1. In an optional mode, the SA mode is an LTE SA mode, and correspondingly, the first RAT is LTE; the terminal device interrupts the first behavior for LTE and the first behavior for NR, and executes the second behavior for an LTE frequency point.

In an example, if it is currently an LTE SA network, it is considered that all measurements involving LTE frequency points, such as an LTE intra-RAT measurement or an NR inter-RAT measurement, cannot be influenced by LTE SRS carrier switching or NR SRS carrier switching.

2. In another optional mode, the SA mode is an NR SA mode, and correspondingly, the first RAT is NR; the terminal device interrupts the first behavior for LTE and the first behavior for NR, and executes the second behavior for an NR frequency point.

In an example, if it is currently an NR SA network, it is considered that all measurements involving NR frequency points, such as an NR intra-RAT measurement or an LTE inter-RAT measurement, cannot be influenced by LTE SRS carrier switching or NR SRS carrier switching.

C4) if the network side configures the terminal device to be in a SA mode, the terminal device interrupts the second behavior and executes the first behavior for a first RAT; wherein a RAT of an access node in the SA mode is the first RAT.

1. In an optional mode, the SA mode is an LTE SA mode, and correspondingly, the first RAT is LTE; the terminal device interrupts the second behavior for LTE and the second behavior for NR, and executes the first behavior for an LTE frequency point.

2. In another optional mode, the SA mode is an NR SA mode, and correspondingly, the first RAT is NR; the terminal device interrupts the second behavior for LTE and the second behavior for NR, and executes the first behavior for an NR frequency point.

According to the above technical solution, the terminal device formulates different terminal device behavior determination methods under different modes or scenarios, so as to give a priority to an important behavior such as cell handover and access, ensure stability of measurement, and give a priority to ensuring that functions such as mobility management, beam management are not interrupted.

Situation Five

If the first behavior and the second behavior are configured to be executed simultaneously, the terminal device determines that the network side has incorrectly configured at least one of first configuration information and second configuration information. Here, the first configuration information is used for the terminal device to execute the first behavior, and the second configuration information is used for the terminal device to execute the second behavior.

In an example, in a case that the first behavior and the second behavior conflict in CGs of different RATs, for example, LTE SRS carrier switching conflicts with an NR measurement, or NR SRS carrier switching conflicts with an LTE measurement, once the two behaviors conflict, the terminal device considers that a network has incorrectly configured. Further, the terminal device may choose to interrupt or discard one behavior according to any one of the above situations one to four, and execute the other behavior.

According to the above technical solution, implementation complexity of the terminal device may be reduced, and a conflict problem is guaranteed by the network side, and the network side may ensure that a conflict situation does not occur by configuring configuration information of the two behaviors.

Situation Six

The second behavior includes a first type of behavior and a second type of behavior, wherein a priority of the first type of behavior is lower than a priority of the second type of behavior; execution of the first behavior can interrupt execution of the first type of behavior but cannot interrupt execution of the second type of behavior.

In an optional mode, a case in which the second behavior is a measurement behavior is taken as an example, distinguishing is performed according to a measurement type, a measurement of the terminal device includes a general measurement (corresponding to the first type of behavior) and one type of special measurement configured by a network (corresponding to the second type of behavior).

In an optional mode, the second type of behavior includes at least one of following: an early measurement behavior, a high-speed rail enhanced measurement behavior, a measurement behavior for fast carrier aggregation establishment, and a measurement behavior for fast dual connectivity establishment.

It should be noted that a special measurement (corresponding to the second type of behavior) configured by the network may be known through an SIB signaling or an RRC dedicated message. Main differences between the special measurement configured by the network and the general measurement are a measured frequency point, a measurement time requirement, etc. Implicitly, a priority of a measurement is also included. Thus, if the terminal device is configured with the special measurement by the network, or reports to the network that a capability supports the special measurement, the first behavior (e.g. SRS carrier switching) is not allowed to affect such type of special measurement even if it may interrupt the general measurement.

The above technical solution satisfies a priority of the special measurement configured by the network.

The technical solution of an implementation of the present disclosure provides the method for determining the behavior of the terminal device. It solves problems of an impact of the first behavior on the second behavior and how the terminal device executes the second behavior, and how to deal with the first behavior (continue execution, suspend, or terminate, and whether continuing execution will bring interruption of the second behavior) when the terminal device may execute the first behavior and the second behavior at the same time (that is, the first behavior and the second behavior conflict).

FIG. 3 is a schematic diagram of structure composition of an apparatus for determining a behavior of a terminal device according to an implementation of the present disclosure, which is applied to the terminal device. As shown in FIG. 3, the apparatus for determining the behavior of the terminal device includes: a determination unit 301, configured to determine that a first behavior and a second behavior are executed simultaneously; wherein the first behavior includes at least one of following: SRS carrier switching, SRS port switching, antenna switching, antenna port switching, BWP switching, cell handover, and MIMO layer switching; the second behavior includes at least one of following: a measurement behavior and a transmission behavior; and an execution unit 302, configured to execute one of the first behavior and the second behavior.

In an optional mode, the execution unit 302 is configured to interrupt the first behavior and execute the second behavior; and execute the first behavior after execution of the second behavior is completed.
