Description

State transition method and device

Technical Field

The present disclosure relates to the field of communications, and in particular, to a state transition method and apparatus.

Background

In 6 months of 2018, the 80 th meeting of 3GPP (3rd Generation Partnership Project) passes through a research Project of 5G NR (New Radio, New air interface), which needs to research a power saving mechanism facing future terminal devices to improve user experience.

In the process of implementing CA (Carrier Aggregation) by NR, multiple serving cells (including a primary cell Pcell and a secondary cell Scell) may be deployed to serve the same terminal device, so as to improve the throughput and rate of the terminal device. When the data volume of the terminal device is small and the resources of the Pcell are sufficient to process the data, the base station may activate/deactivate a part of scells, and may notify the terminal device of which scells are activated/deactivated through the MAC CE information for indicating the activation/deactivation of the scells. For the activated Scell, the terminal device does not monitor a PDCCH (Physical Downlink Control Channel) indicated on the Scell any more, so as to save the power of the terminal device.

However, in the related art, when data of the terminal device changes, the base station does not deactivate some scells in time, so that the terminal device still needs to monitor PDCCHs on the scells, thereby causing a problem of power waste.

In order to solve the above problem, it is proposed to apply an SCell dormant State (SCell dormant State) mechanism to the NR, and when the SCell is in the dormant State, the terminal device does not monitor the PDCCH on the SCell any more, but may perform operations such as CSI (Channel State Information)/RRM (Radio Resource Management) measurement, so that after the SCell is activated again, the base station may adjust a Resource scheduling policy according to a CSI/RRM measurement result of the SCell by the terminal device, so as to provide a more adaptive Resource for the terminal device, and further, while improving throughput and rate of the terminal device, may reduce waste of power of the terminal device.

Therefore, if after introducing the SCell dormant state into the NR, how to perform the activation/deactivation of the SCell and the transition of the sleep state is a problem to be solved.

Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In the drawings, like reference numbers can indicate functionally identical or similar elements. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

Fig. 1 illustrates a flowchart of a state transition method according to an embodiment of the present disclosure, which may be applied to a terminal device. As shown in fig. 1, the method may include:

step 101, receiving serving cell state indication information, where the serving cell state indication information includes an index identifier of a serving cell and state transition indication information of the serving cell.

For example, the base station may convert the state of the serving cell according to the data amount of the terminal device, and send corresponding serving cell state indication information to the terminal device through the serving cell (the base station may send the serving cell state indication information to the terminal device through the serving cell in an active state, but may not send the serving cell state indication information to the terminal device through the serving cell in a dormant state). The serving cell state indication information may include an index identifier of a serving cell and state transition indication information of the serving cell, where the index identifier of the serving cell is used to indicate the serving cell that has performed state transition, and the state transition indication information of the serving cell may be used to indicate that the serving cell identified by the corresponding index identifier has performed corresponding state transition, for example: indicating that the serving cell has transitioned from a deactivated state to an activated state, or from a dormant state to a deactivated state, or from an activated state to a dormant state, or from an activated state to a deactivated state.

And step 102, determining a first serving cell according to the index identifier.

After receiving the serving cell state indication information, the terminal device may determine that the serving cell identified by the index identifier is a first serving cell, and the first serving cell is a serving cell subjected to state conversion. For example: the serving cell state indication information includes an index identifier 002, and the serving cell corresponding to the index identifier 002 is the SCell2, the terminal device may determine that the SCell2 is the first serving cell.

And 103, determining the current state of the first serving cell.

And 104, determining the state of the first serving cell according to the state transition indication information and the current state of the first serving cell.

After the terminal device determines the first serving cell, the current state of the first serving cell may be locally obtained from the terminal device (for example, the local first serving cell has a state identifier, and the terminal device may determine the current state of the first serving cell according to the state identifier of the first serving cell), and determine the state of the first serving cell according to the state transition indication information for the first serving cell and the current state of the first serving cell.

In this way, the terminal device may receive the serving cell state indication information, determine the first serving cell according to the index identifier in the serving cell state indication information, and determine the state of the first serving cell according to the state transition indication information in the serving cell state indication information and the current state of the first cell after determining the current state of the first serving cell. According to the state transition method provided by the embodiment of the disclosure, the terminal device can rapidly deal with the processing after the state transition of the first serving cell.

For example: in a scenario that NR implements CA, the terminal device may determine that the first serving cell has been converted from the dormant state to the active state according to the active state indicated by the serving cell state indication information; or the terminal device may determine that the first serving cell has been switched from the dormant state to the deactivated state according to the deactivated state indicated by the serving cell state indication information; or the terminal device may determine that the first serving cell has been converted from the active state to the dormant state according to the dormant state indicated by the serving cell state indication information, and the terminal device may implement some operations after the activation/deactivation of the serving cell and the conversion of the dormant state.

In a possible implementation manner, the determining the state of the first serving cell according to the state transition indication information and the current state of the first serving cell may include:

For example, when the state transition indication information includes first identification information (the first identification information may be used to indicate that the first serving cell is in an active state), and the terminal device determines that the current state of the first serving cell is in a dormant state (the first serving cell in the terminal device local area has second identification information, and the second identification information is used to indicate that the first serving cell is in the dormant state), the terminal device may determine that the state of the first serving cell is in the active state.

For example, when the state transition indication information includes first identification information (the first identification information may be used to indicate that the first serving cell is in an activated state), and the terminal device determines that the current state of the first serving cell is in a deactivated state (the first serving cell in the terminal device local area has third identification information, and the third identification information is used to indicate that the first serving cell is in a deactivated state), the terminal device may determine that the state of the first serving cell is in the activated state.

For example, when the state transition indication information includes third identification information (the third identification information may be used to indicate that the first serving cell is in a deactivated state), and the terminal device determines that the current state of the first serving cell is in a dormant state (the first serving cell in the terminal device local area has second identification information, and the second identification information is used to indicate that the first serving cell is in the dormant state), the terminal device may determine that the state of the first serving cell is in the deactivated state.

For example, when the state transition indication information includes third identification information (the third identification information may be used to indicate that the first serving cell is in the deactivated state), and the terminal device determines that the current state of the first serving cell is the activated state (the first serving cell in the local area of the terminal device has the first identification information, and the first identification information is used to indicate that the first serving cell is in the activated state), the terminal device may determine that the state of the first serving cell is the deactivated state.

For example, when the state transition indication information includes second identification information (the second identification information is used to indicate that the first serving cell is in the dormant state), and the terminal device determines that the current state of the first serving cell is the active state (the first serving cell in the local area of the terminal device has the first identification information, which is used to indicate that the first serving cell is in the active state), the terminal device may determine that the state of the first serving cell is the dormant state.

It should be noted that, when the state transition indication information indicates that the first serving cell is in the dormant state and the current state of the first serving cell is the deactivated state, the terminal device may determine that the serving cell state indication information is invalid information and does not respond to the invalid information.

Thus, according to the state transition method provided by the embodiment of the present disclosure, after the first serving cell performs the transition processing between the dormant state and the activated/deactivated state, the method includes: the method comprises the steps of switching from a dormant state to an activated state, switching from the dormant state to a deactivated state and switching from the activated state to the dormant state, determining the state of a first service cell and executing corresponding operation on the first service cell.

In a possible implementation manner, the state transition indication information may include an active state identifier and a dormant state identifier, where the active state identifier is used to indicate that the serving cell is in an active state or a deactivated state, and the dormant state identifier is used to indicate whether the serving cell is in a dormant state.

For example, the state transition indication information may include 2 bits, where 1bit is an active state identifier, which may be used to indicate that the serving cell is in an active state/a deactivated state (for example, when the active state identifier is 1, it may indicate that the first serving cell is in an active state, and when the active state identifier is 0, it may indicate that the first serving cell is in a deactivated state), and another bit is a dormant state identifier, which may be used to indicate whether the serving cell is in a dormant state (for example, when the dormant state identifier is 1, it may indicate that the first serving cell is in a dormant state, and when the dormant state identifier is 0, it may indicate that the first serving cell is not in a dormant state).

For example: the state transition indication information is 00, which may identify that the first serving cell is in a deactivated state and not in a dormant state; the state transition indication information is 01, which may identify that the first serving cell is in an active state and not in a dormant state; the state transition indication information is 11, and may identify that the first serving cell is in an active state and in a dormant state.

For example, the state transition indication information in the serving cell state indication information received by the terminal device is 11, that is, the state transition indication information indicates that the first serving cell is in the active state and in the dormant state. The terminal device may obtain the state identifier of the first serving cell from the local, and when the state identifier of the first serving cell in the local is 01, the terminal device determines that the current state of the first serving cell is the active state, and then the terminal device may determine that the state of the first serving cell is the dormant state according to the determination state transition indication information 11 (dormant state) and the current state 01 (active state), and the terminal device may set the state identifier of the first serving cell to 11. After determining that the first serving cell is in the dormant state, the terminal device does not monitor the physical downlink control channel PDCCH of the first serving cell any more, and may perform operations such as CSI/RRM measurement in the first serving cell.

For example, the state transition indication information in the serving cell state indication information received by the terminal device is 01, that is, the state transition indication information indicates that the first serving cell is in the active state and not in the dormant state. The terminal device may obtain the state identifier of the first serving cell from the local, and when the state identifier of the first serving cell in the local is 11 (or 00), the terminal device determines that the current state of the first serving cell is a dormant state (or a deactivated state), and then the terminal device may determine that the state of the first serving cell is an activated state according to the determination state transition indication information 01 and the current state 11 (or 00), and the terminal device may set the state identifier of the first serving cell to 01. After determining that the first serving cell is in the activated state, the terminal device starts to monitor a physical downlink control channel PDCCH of the first serving cell, and may perform operations such as CSI/RRM measurement in the first serving cell.

For example, the state transition indication information in the serving cell state indication information received by the terminal device is 00, that is, the state transition indication information indicates that the first serving cell is in the deactivated state and not in the dormant state. The terminal device may obtain the state identifier of the first serving cell from the local, and when the state identifier of the first serving cell in the local is 01 (or 11), the terminal device determines that the current state of the first serving cell is an active state (or a dormant state), and then the terminal device may determine that the state of the first serving cell is a deactivated state according to the determination state transition indication information 00 and the current state 01 (or 11), and may set the state identifier of the first serving cell to 00. After determining that the first serving cell is in the deactivated state, the terminal device does not monitor the physical downlink control channel PDCCH of the first serving cell any more, and does not perform operations such as CSI/RRM measurement on the first serving cell.

In a possible implementation manner, the serving cell status indication information may be carried by downlink control DCI information.

The base station may send downlink control DCI information to the terminal device through the serving cell, where the downlink control DCI information may include an index identifier of the serving cell and state transition indication information of the serving cell, and the downlink control DCI information is physical layer information, so that the embodiment of the present disclosure may quickly perform state transition processing on the serving cell, and may enable the terminal device to quickly cope with processing operations after state transition of the serving cell.

In a possible implementation manner, the serving cell status indication information may be carried by first MAC CE information and/or second MAC CE information, where the first MAC CE information includes an index identifier and an active status identifier of a serving cell, and the second MAC CE information may include an index identifier and a dormant status identifier of the serving cell.

For example, the base station may determine the transition state of the serving cell according to the data amount of the terminal device, and send corresponding MAC CE information, for example: the base station may send the first MAC CE information to the terminal device when determining that the transition state of the serving cell is the activation/deactivation state; the base station may transmit the second MAC CE information to the terminal device when it is determined that the transition state of the serving cell is the dormant state.

For example, if the terminal device receives the second MAC CE information, the terminal device may determine whether the terminal device is currently in an active state, and further determine the state of the first serving cell according to the second MAC CE information and the current state of the terminal device. For example: the dormant state identifier of the first serving cell in the second MAC CE information is 1, and the terminal device determines that the first serving cell is currently in an active state (the current state identifier of the local first serving cell is 01), and the terminal device may determine that the state identifier of the first serving cell is 11, and determine that the state of the first serving cell is in a dormant state; or, the dormant state identifier of the first serving cell in the second MAC CE information is 0, and the terminal device determines that the first serving cell is currently in an active state (the current state identifier is 01), and the terminal device may determine that the state identifier of the first serving cell is 01, and determine that the state of the first serving cell is in an active state; or, the dormant state identifier of the first serving cell in the second MAC CE information is 0, and the terminal device determines that the first serving cell is currently in a deactivated state (the current state identifier of the local first serving cell is 00), and the terminal device may determine that the state identifier of the first serving cell is 00, and determine that the state of the first serving cell is in a deactivated state.

It should be noted that, when the dormant state identifier of the first serving cell in the second MAC CE information is 1 and the terminal device determines that the first serving cell is currently in the deactivated state, the terminal device determines that the second MAC CE information is invalid information and does not perform any processing.

If the terminal device receives the first MAC CE information, the terminal device may determine whether the terminal device is currently in a dormant state, and then determine a state of the first serving cell according to the first MAC CE information and the current state of the terminal device. For example: the activation state identifier of the first serving cell in the first MAC CE information is 1, and the terminal device determines that the first serving cell is currently in a dormant state (the current state identifier of the local first serving cell is 11), and the terminal device may determine that the state identifier of the first serving cell is 01, and determine that the state of the first serving cell is an activation state; or, the activation state identifier of the first serving cell in the first MAC CE information is 1, and the terminal device determines that the first serving cell is not in the dormant state currently (the current state identifier of the local first serving cell is 00 or 01), the terminal device may determine that the state identifier of the first serving cell is 01, and determine that the state of the first serving cell is the activation state; or when the activation status identifier of the first serving cell in the first MAC CE information is 0, the terminal device determines that the first serving cell is currently in a dormant state or an un-dormant state (the current status identifier of the local first serving cell is 00 or 01), and the terminal device may determine that the status identifier of the first serving cell is 00, and in order to determine that the status of the first serving cell is in a deactivated state.

For another example, if the terminal device receives the first MAC CE information and the second MAC CE information, where the activation state identifier of the first serving cell in the first MAC CE is 1, the dormant state identifier of the first serving cell in the second MAC CE information is 1, and the terminal device determines that the current state of the first serving cell is the activation state (the current identifier state of the local first serving cell is 01), the terminal device may determine that the state identifier of the first serving cell is 11, and determine that the first serving cell is in the dormant state. Or, if the activation state identifier of the first serving cell in the first MAC CE is 1, the dormant state identifier of the first serving cell in the second MAC CE information is 0, and the terminal device determines that the current state of the first serving cell is a dormant state (the current identifier state of the local first serving cell is 11), the terminal device may determine that the state identifier of the first serving cell is 01, and determine that the first serving cell is in the activation state. Or, if the activation state identifier of the first serving cell in the first MAC CE is 0, the dormant state identifier of the first serving cell in the second MAC CE information is 0, and the terminal device determines that the current state of the first serving cell is a dormant state (the current identifier state of the local first serving cell is 11), the terminal device may determine that the state identifier of the first serving cell is 00, and determine that the first serving cell is in a deactivated state.

It should be noted that, when the activation state identifier of the first serving cell in the first MAC CE is 1, the dormant state identifier of the first serving cell in the second MAC CE information is 1, and the terminal device determines that the current state of the first serving cell is the deactivation state (the current identifier state of the local first serving cell is 00), the terminal device may determine that the serving cell state indication information is invalid information, and does not respond to the invalid information.

In one possible implementation manner, referring to fig. 2, the method may further include:

and step 105, determining the bandwidth of the target part carrier.

The NR introduces the concept of partial carrier bandwidth (BWP, Band width part), and for the connected terminal, the base station already knows the bandwidth capability of the connected terminal, and the base station can configure one or more BWPs for the terminal according to the bandwidth capability of the terminal for the transmission requirements of different services. The base station may configure a control resource set and a search space for each BWP to ensure that the connected terminal monitors the PDCCH on the activated BWP to receive scheduling resources for transceiving data. At R15 NR, only one active BWP at a time is supported. And therefore on which BWP the terminal should operate accordingly, is a problem to be solved.

In NR, the base station configures no more than 4 BWPs for each SCell for dynamic data scheduling, and at the same time, there is only one active BWP per SCell, and when an SCell is in an active state, the terminal device may monitor a physical downlink control channel PDCCH on the active BWP and perform measurement operations (e.g., CSI/RRS measurement, etc.); when the SCell is in the dormant state, the terminal device may perform a measurement operation on the BWP in the active state, but does not monitor a physical downlink control channel PDCCH thereof, so that after the SCell is reactivated, the base station may perform resource scheduling according to a measurement result of the BWP in the active state by the terminal device, so that the base station can provide more accurate resource scheduling for the terminal device, and further save power of the terminal device.

After receiving the serving cell state indication information, the terminal device may determine a target BWP from the BWPs configured in the first serving cell, where the target BWP is a BWP to be subjected to bandwidth quality measurement by the terminal device.

In a possible implementation manner, the serving cell status indication information may further include a target partial carrier bandwidth identifier, and the determining the target partial carrier bandwidth may include:

and determining a target partial carrier bandwidth according to the target BWP identification.

In a possible implementation manner, the serving cell state indication information may be carried by downlink control DCI information, where the downlink control DCI information may include an index identifier of a serving cell, state transition indication information of the serving cell, and a target BWP identifier. The end device may determine that the BWP indicated by the target BWP identification is the target BWP.

In a possible implementation manner, the serving cell status indication information may be carried by first MAC CE information and/or second MAC CE information, where the first MAC CE information and the second MAC CE information include a target part carrier bandwidth identifier.

in this embodiment, the determining the target partial carrier bandwidth may include:

and when the first service cell is in a dormant state, determining that the target partial carrier bandwidth is the partial carrier bandwidth identified by the dormant partial carrier bandwidth identification.

The base station may send, to the terminal device, Radio Resource Control (RRC) signaling through the serving cell, where the RRC signaling may include a dormant BWP identifier, so as to semi-statically indicate a dormant BWP of an SCell through RRC signaling. While the first serving cell is in the dormant state, the terminal device may determine that the dormant BWP is the target BWP.

In a possible implementation manner, the determining the target partial carrier bandwidth may include:

When the first serving cell is in the dormant state, the terminal device may determine that the target BWP is a default BWP (default BWP).

And 106, determining the operation aiming at the target partial carrier bandwidth according to the state of the first serving cell.

For example, the processing operation of the state of the first serving cell and the target BWP may refer to table 1 below.

TABLE 1

In a possible implementation manner, the determining the target fractional carrier bandwidth according to the state of the first serving cell may include:

In a possible implementation manner, the method may further include:

and performing measurement operation on the target partial carrier bandwidth.

When the first serving cell is in the dormant state, the terminal device does not perform PDCCH monitoring on the target BWP any more, and may perform measurement operations on the target BWP only, for example: performing a CSI/RRS measurement operation.

In a possible implementation manner, the method may further include:

and performing measurement operation on the target partial carrier bandwidth.

When the first serving cell is in the dormant state, the terminal device may perform PDCCH monitoring on a physical downlink control channel (BWP) for a target BWP, and may perform measurement operations on the target BWP, for example: performing a CSI/RRS measurement operation.

deactivating the target serving carrier bandwidth when the first serving cell is in a deactivated state; wherein the target serving carrier bandwidth is a part of the carrier bandwidth of the first serving cell currently in an active state; or, the target serving carrier bandwidth is a part of the carrier bandwidth in the dormant state in the first serving cell.

When the first serving cell is in the deactivated state, the terminal device does not perform the PDCCH monitoring and measuring operation on the physical downlink control channel on any BWP (including the target BWP and the currently activated BWP) configured in the first serving cell. When the first serving cell is converted from the dormant state to the deactivated state, the target BWP is the BWP in the dormant state in the first serving cell, and the terminal device may deactivate the BWP currently in the dormant state in the first serving cell; when the first serving cell is converted from the active state to the deactivated state, the target BWP is the BWP currently in the active state in the first serving cell, and the terminal device may deactivate the BWP currently in the active state in the first serving cell.

Note that, when the serving cell is in the dormant state, the BWP in the dormant state in the serving cell may actually be considered as the BWP in the active state.

In a possible implementation manner, referring to fig. 3, after determining the target partial carrier bandwidth, the terminal device may further include:

step 107, determining the partial carrier bandwidth currently in the active state or the partial carrier bandwidth in the dormant state in the first serving cell.

Step 108, when the partial carrier bandwidth in the activated state is inconsistent with the target partial carrier bandwidth, deactivating the partial carrier bandwidth in the activated state and activating the target partial carrier bandwidth,

After the first serving cell is converted from the active state to the dormant state, the terminal device determines whether the target BWP of the first serving cell is currently the target BWP, if so, performs a corresponding operation on the target BWP directly according to the state of the first serving cell (may hibernate the target BWP), otherwise, deactivates the BWP in the active state, and performs a corresponding operation on the target BWP according to the state of the first serving cell after activating the target BWP (or hibernating the target BWP).

Or, after the first serving cell is converted from the dormant state to the active state, the terminal device determines whether the target BWP of the first serving cell is the BWP currently in the dormant state (or may also be the BWP in the active state), if so, performs a corresponding operation on the target BWP (may activate the target BWP) directly according to the state of the first serving cell, otherwise, deactivates the BWP in the dormant state, and after activating the target BWP, performs a corresponding operation on the target BWP according to the state of the first serving cell.

Therefore, the base station can adjust the BWP monitored or measured by the terminal device according to the data volume processed by the terminal device, so that the base station can better schedule resources for the terminal device according to the measurement result reported by the terminal device, the throughput is improved, and the power consumption of the terminal device can be reduced.

In one possible implementation manner, referring to fig. 4, the method may further include:

step 109, when determining that the first serving cell is in the dormant state, starting a timer mechanism;

step 110, during the time period of the timer mechanism, if no indication information indicating that the first serving cell is switched to the activated state or the deactivated state is received, the timer is overtime to determine that the first serving cell is in the deactivated state.

The terminal device may start a timer mechanism after determining that the first serving cell is in the dormant state. If the terminal device does not receive the indication information indicating that the first serving cell is switched to the activated state or the deactivated state during the timing of the timer mechanism, it may be determined that the first serving cell is in the deactivated state when the timer is overtime, so that even if the base station does not perform activation/deactivation processing on the first serving cell in time, the terminal device may not generate unnecessary power consumption due to monitoring the first serving cell, and may save power.

The currently activated serving cell includes SCell1 and SCell2, and BWP1 and BWP2 are configured in SCell1, where BWP2 is in an activated state. The base station decides to transfer SCell1 into the dormant state according to the current data volume of the terminal device, and then the base station may send downlink control DCI information to the terminal device through serving cell SCell1 or SCell2, where the downlink control DCI information includes: index identification of serving cell: 001. state transition indication information of the serving cell: 11. target BWP identification: 1.

The terminal apparatus determines the state of the SCell1 as a dormant state (state identification is 11) according to the state transition indication information 11 (dormant state) of the serving cell and the current state (active state) of the SCell 1.

The terminal device determines that the target BWP is BWP1 and that in SCell1 in active state is BWP2, the terminal device may activate BWP1 (or sleep BWP1), and upon deactivation BWP2, perform CSI/RRS measurements on BWP 1.

The terminal apparatus determines the state of SCell1 as the active state (state identification as 11) according to state transition indication information 01 (active state) and the current state of SCell1 (sleep state).

The terminal device determines that the target BWP is BWP1 and that in the SCell1 in the active state (dormant state) is BWP1, so the terminal device performs PDCCH listening to BWP1 and performs CSI/RRS measurement on BWP 1.

after receiving the downlink control DCI information, the terminal device determines that the first serving cell is SCell1 according to the index identifier 001, and the terminal device determines that the current state of SCell1 is an active state (the current state identifier of local SCell1 is 01). The terminal apparatus determines the state of SCell1 as the sleep state according to state transition indication information 11 (sleep state) and the current state (active state) of SCell 1.

When the SCell is in the dormant state, the terminal device may determine that the target BWP is BWP1 according to RRC signaling, and BWP2 in the SCell1 in the active state, and then the terminal device may activate BWP1 and perform CSI/RRS measurement on BWP1 after deactivating BWP 2.
