[0031] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).
[0032] Cell DTX / DRX
[0033] In some protocols (e.g., 5G R18), cell DTX / DRX is introduced to reduce the activation time of downlink transmission and uplink reception in order to lower the power consumption of network equipment. Terminal equipment can be configured with a periodic cell DTX / DRX mode. Within the same cell, the cell DTX / DRX configuration of terminal equipment with this feature is common. Correspondingly, cell DTX and cell DRX can be configured and activated separately. A maximum of two cell DTX / DRX modes can be configured in different serving cells within each MAC entity. Cell DTX / DRX is only applicable to connected terminal equipment and does not affect random access procedures, synchronization signal / PBCH block (SSB) transmission, paging, or system message broadcasting.
[0034] In some implementations, cell DTX / DRX operation only supports a single TRP scenario. Cell DTX / DRX activation or deactivation can be indicated via RRC signaling or L1 group common signaling (e.g., DCI2-9). When cell DTX and cell DRX are configured simultaneously, the activation time and period parameters are the same for both.
[0035] In some implementations, when a cell DTX is configured and activated, the terminal device may not listen to the physical downlink control channel (PDCCH) or the semi-persistent scheduling (SPS) during the cell DTX non-active duration. Additionally, during the cell DTX active duration, the terminal device starts the cellDTX-DRX-onDurationTimer. This timer can be started using the formula [(SFN×10)+subframe number]modulo(cellDTX-DRX-Cycle)=(cellDTX-DRX-StartOffset), where SFN represents the terminal device's system frame number, subframe number represents the number of subframes, cellDTX-DRX-Cycle represents the cell DTX / DRX cycle, and cellDTX-DRX-StartOffset represents the cell DTX / DRX start time offset, used to determine the start time of the cellDTX-DRX-onDurationTimer.
[0036] In some implementations, if the cell DTX operation is deactivated or the serving cell is active, the terminal device can listen to the serving cell's PDCCH. If any DRX retransmission timer is running, or a conflict resolution timer is running, or an SR is waiting to be sent, or a new transmission indicated by the PDCCH has not yet been received, the terminal device needs to continue listening to the PDCCH on this serving cell. Additionally, if the RS-ResponseWindow is running, the terminal device needs to listen to the PDCCH on this serving cell.
[0037] In some implementations, when cell DTX operation is activated and the serving cell is not in the cell DTX active period, the MAC entity may not need to perform PDCCH listening for the MAC entity's RNTI, nor may it need to instruct the physical layer to receive transport blocks on the DL-SCH according to the downlink configuration of the SPS.
[0038] In some implementations, when a cell is configured with and activated DRX, the terminal device does not transmit CG resources or send SRs during the DRX non-active period. When the serving cell is configured with and activated DRX, the DRX activation time includes the runtime of cellDTX-DRX-onDurationTimer. Furthermore, the time when the terminal device starts cellDTX-DRX-onDurationTimer can be determined using the formula [(SFN×10)+subframe number]modulo(cellDTX-DRX-Cycle)=(cellDTX-DRX-StartOffset), where SFN represents the system frame number of the terminal device, subframe number represents the number of subframes, cellDTX-DRX-Cycle represents the cell DTX / DRX cycle, and cellDTX-DRX-StartOffset represents the start time offset of cell DTX / DRX, used to determine the start time of cellDTX-DRX-onDurationTimer.
[0039] In some implementations, if the cell DRX is activated but the cell is not within the DRX activation period, the terminal device's behavior includes: not instructing the physical layer to send an SR, not incrementing the SR_COUNTER, not starting the sr-ProhibitTimer, not transmitting any configuration uplink grant and related HARQ information to the HARQ entity, not instructing the HARQ procedure to trigger new transmissions and retransmissions, not reporting CSI on the PUCCH, and not reporting SP-CSI on the PUSCH. Additionally, if an emergency service is triggered by the upper layer, the terminal device triggers a random access procedure.
[0040] Currently, to reduce network energy consumption, cell DTX and / or DRX mechanisms have been introduced to decrease the activation time of downlink transmission and uplink reception in network devices. However, the power consumption savings achieved by these cell DTX and / or DRX mechanisms are relatively limited, resulting in still relatively high power consumption for network devices.
[0041] As mentioned earlier, the current cell DTX / DRX mechanism offers limited power savings for network devices because it is designed for connected terminal devices. For disconnected terminal devices, signaling transmissions involved in some basic processes (such as RA, paging, SSB transmission, and system broadcast messages) are not affected by the cell DTX / DRX mechanism. Therefore, network devices need to remain operational to transmit these signaling messages, resulting in limited power savings for network devices under this cell DTX and / or DRX mechanism.
[0042] Therefore, to address the aforementioned problems, this application introduces a first mode in which a cell (hereinafter referred to as "the first cell") can communicate with a terminal device in a disconnected state based on cell DRX and / or cell DTX mechanisms. In other words, the first cell can perform discontinuous communication with the terminal device in a disconnected state, which helps save power consumption required for communication between network devices and terminal devices in a disconnected state. The wireless communication method in this application embodiment is described below with reference to FIG2. The method shown in FIG2 includes step S210.
[0043] In step S210, the terminal device communicates with the first cell based on a first mode, wherein the first mode is used to instruct the terminal device in the cell DRX and / or cell DTX to communicate with the terminal device in the non-connected state.
[0044] In some scenarios, the first mode can be understood as extending the traditional cell DRX and / or cell DTX mechanisms to scenarios where communication is with non-connected terminal devices. Compared to the traditional cell DRX and / or cell DTX mechanisms, which only restrict communication with connected terminal devices, this mode helps to further save the power consumption required for communication between network devices and terminal devices.
[0045] In some implementations, a cell in cell DRX and / or cell DTX can include one of the following: a cell in cell DRX, a cell in cell DTX, or a cell in both cell DTX and cell DRX (referred to as cell DTX / DRX).
[0046] In some scenarios, the first mode can also be referred to as Deep Cell DRX and / or Deep Cell DTX. Correspondingly, a cell in DRX mode can be called a cell in Deep Cell DRX mode (or a cell that only supports DRX mode), a cell in DTX mode can be called a cell in Deep Cell DTX mode (or a cell that only supports DTX mode), and a cell in DTX / DRX mode can be called a cell in Deep Cell DTX / DRX mode (or a cell that supports both DTX and DRX modes).
[0047] It should be noted that the name of the first mode described above is not limited in the embodiments of this application. The first mode may also be given other names with similar functions in future communication systems.
[0048] Furthermore, it should be noted that the first cell can simultaneously support multiple modes mentioned above. For example, the first cell can simultaneously support Deep Cell DTX / DRX and Deep Cell DRX. Alternatively, the first cell can simultaneously support Deep Cell DTX / DRX, Deep Cell DRX, and Deep Cell DTX. Or, the first cell can simultaneously support Deep Cell DTX / DRX and Deep Cell DTX. Of course, in this embodiment, the first cell may only support one of the above modes. For example, the first cell may only support Deep Cell DTX / DRX. Alternatively, the first cell may only support Deep Cell DRX. Or, the first cell may only support Deep Cell DTX.
[0049] In some implementations, the terminal device in the non-connected state may include a terminal device in the idle state and / or a terminal device in the inactive state. In other words, the first mode is used to instruct the terminal device in the cell DRX and / or cell DTX to communicate with the terminal device in the idle state and / or the terminal device in the inactive state.
[0050] In some implementations, the first mode includes a cell DTX mode, and the first cell is in the first mode. During the inactive period (also known as the off-duration) of the first mode, the first cell does not transmit downlink signals or downlink channels. Correspondingly, during the active period (also known as the on-duration) of the first mode, the first cell transmits downlink signals or downlink channels.
[0051] In some implementations, the first mode including cell DTX mode can be understood as the first mode including deep cell DTX or deep cell DTX / DRX.
[0052] In this application embodiment, the downlink signal or downlink channel is not limited. In some implementations, the downlink signal or downlink channel can be understood as the downlink signal or downlink channel transmitted between the cell and the non-connected terminal device. For example, the downlink signal includes one or more of the following: SSB, system information, paging message, PEI, LP-WUS, LP-SS.
[0053] In some implementations, the first mode includes a cell DRX mode, and the first cell is in the first mode. During the inactive period (also known as the off-duration) of the first mode, the first cell does not receive uplink signals or uplink channels; that is, during the off-duration of the first mode, the terminal device does not transmit uplink signals or uplink channels in the first cell. Correspondingly, during the active period (also known as the on-duration) of the first mode, the first cell receives uplink signals or uplink channels.
[0054] In some implementations, the first mode including cell DRX mode can be understood as the first mode including deep cell DRX or deep cell DTX / DRX.
[0055] In this application embodiment, the uplink signal or uplink channel is not limited. In some implementations, the uplink signal or uplink channel can be understood as the uplink signal or uplink channel transmitted between the cell and the disconnected terminal device. For example, the uplink signal includes random access signal and / or SDT.
[0056] In some scenarios, the initial activation time of the first mode can be determined based on the first timer. Correspondingly, the start time of the first timer is determined based on the SFN and / or the period of the first mode. In some scenarios, the first timer is also called the "OnDuration Timer".
[0057] In some implementations, the start time of the first timer is the start activation time of the first mode. Accordingly, the start activation time can be determined based on the time offset of the start activation time of the first mode. For more information on the time offset of the start activation time of the first mode, please refer to the following text.
[0058] For example, the time offset OnStartOffset of the start activation time of the first mode can be determined based on the formula: [(SFN×10)+N]modulo(T1)=(OnStartOffset), where N represents the number of subframes, SFN represents the system frame number corresponding to the terminal device, and T1 represents the period of the first mode.
[0059] In some scenarios, the initial inactivity period of the first mode can be determined based on a second timer. Correspondingly, the start time of the second timer is determined based on the SFN and / or the period of the first mode. In some scenarios, the second timer is also referred to as an "OffDuration Timer".
[0060] In some implementations, the start time of the second timer is the same as the start inactivity time of the first mode. Accordingly, the start inactivity time can be determined based on the time offset of the start inactivity time of the first mode. For more information on the time offset of the start inactivity time of the first mode, please refer to the following text.
[0061] For example, the time offset OffStartOffset of the start inactive time of the first mode can be determined based on the formula: [(SFN×10)+N]modulo(T1)=(OffStartOffset), where N represents the number of subframes, SFN represents the system frame number corresponding to the terminal device, and T1 represents the period of the first mode.
[0062] Typically, for a terminal device in an idle state, if the first cell is in the inactive period of the first mode, the first cell does not transmit any downlink signals or downlink channels, and the terminal device may not be able to acquire the SFN. In this case, the terminal device cannot determine the start time of the first timer. Therefore, this application embodiment introduces a scheme to determine the time offset OffStartOffset of the start inactive period. The terminal device can then determine OffStartOffset based on the SFN acquired during the active period of the first mode to determine the start time of the offDurationTimer. When the offDurationTimer expires, the first cell enters the active period of the first mode, and the terminal device can perform normal measurements.
[0063] In some implementations, the SFN is acquired by the terminal device during the activation time of the first mode, or the SFN is acquired by the terminal device in the connected state.
[0064] In some implementations, the above method further includes: in response to the terminal device switching from a connected state to a disconnected state, the terminal device and / or the network device maintain a first timer and / or a second timer.
[0065] In some implementations, a first time interval is used between the activation time of the first mode and the transmission time of the paging message, the paging message is used for the paging terminal equipment of the first cell, and the first time interval is used for SSB measurement.
[0066] In some implementations, the paging message transmission time falls within the active time of the first mode.
[0067] In this embodiment, the first time interval is not limited. For example, the first time interval may be the time interval between the start activation time of the first mode and the start transmission time of the paging message. For example, the first time interval may be the time interval between the start activation time of the first mode and the end transmission time of the paging message.
[0068] For example, when the Deep Cell DTX or Deep Cell DTX / DRX of a cell is active but inactive, the terminal device does not listen for paging messages. In this case, a time interval can be reserved between the start activation time of the Deep Cell DTX / DRX and the transmission time of the paging message, so that the terminal device can perform SSB measurements within this time interval.
[0069] The first timer and the second timer in the embodiments of this application have been introduced above. The first mode based on the first timer and the second timer is described below.
[0070] Example 1: Assume the first timer is onDurationTimer, the second timer is offDurationTimer, and the first mode includes Deep Cell DTX or Deep Cell DTX / DRX.
[0071] In some implementations, the terminal device performs normal RACH operations while onDurationTimer is running or offDurationTimer is not running.
[0072] In some implementations, when the offDurationTimer is running or the onDurationTimer is not running, the terminal device's behavior includes one or more of the following: the terminal device does not perform paging message listening; the terminal device does not perform paging early indication (PEI) listening; the terminal device does not perform low power-wake up signal (LP-WUS) listening; the terminal device does not perform SSB-based measurements and maintains the original SSB measurement results (when the terminal device's movement speed is relatively slow); the terminal device does not perform low power-synchronization signal (LP-SS)-based measurements; the terminal device maintains the received system broadcast information and does not receive system broadcast information; the terminal device determines the start activation time of the first mode in neighboring cells.
[0073] In some implementations, when the offDurationTimer is running or the onDurationTimer is not running, the first cell does not send downlink signals such as SSB, system broadcast, and paging messages during the inactive time of the first mode.
[0074] Example 2: Assume the first timer is onDurationTimer, the second timer is offDurationTimer, and the first mode includes Deep Cell DRX or Deep Cell DTX / DRX.
[0075] In some implementations, while onDurationTimer is running or offDurationTimer is not running, the terminal device performs normal listening, paging, and measurement operations within the first cell.
[0076] In some implementations, the terminal device’s behavior may include not triggering the random access channel (RACH) procedure during the operation of offDurationTimer or when onDurationTimer is not running, and / or not triggering the short data transfer (SDT) procedure.
[0077] The first mode in the embodiments of this application has been introduced above. The scheme for configuring the first mode in the embodiments of this application is described below. In some implementations, the above method further includes: the first cell sending configuration information to the terminal device, the configuration information being used to configure the first mode.
[0078] In some implementations, the configuration information carries one or more of the following: indication information for the first mode; activation indication information for the first mode; periodic information for the first mode; activation time information for the first mode; activation time information for the first mode in neighboring cells; and inactivity time information for the first mode.
[0079] Taking the configuration information carrying indication information of the first mode as an example, in some implementations, the indication information of the first mode is used to indicate the first mode. For example, if the first mode is Deep Cell DTX, then the indication information of the first mode is used to indicate that the first mode is Deep Cell DTX. As another example, if the first mode is Deep Cell DRX, then the indication information of the first mode is used to indicate that the first mode is Deep Cell DRX. As yet another example, if the first mode is Deep Cell DTX / DRX, then the indication information of the first mode is used to indicate that the first mode is Deep Cell DTX / DRX.
[0080] Taking the configuration information carrying the activation instruction information of the first mode as an example, in some implementations, the activation instruction information of the first mode is used to indicate the activation of the first mode, or in other words, the activation instruction information of the first mode is used to indicate the enabling of the first mode, or in other words, the activation instruction information of the first mode is used to indicate the entry into the first mode.
[0081] For example, if the first mode is Deep Cell DTX, then the activation indication information for the first mode is used to indicate the activation of Deep Cell DTX. As another example, if the first mode is Deep Cell DRX, then the indication information for the first mode is used to indicate the activation of Deep Cell DRX. As yet another example, if the first mode is Deep Cell DTX / DRX, then the indication information for the first mode is used to indicate the activation of Deep Cell DTX / DRX.
[0082] Taking the configuration information carrying the period information of the first mode as an example, in some implementations, the period information of the first mode is used to indicate one or more of the following: the duration of the period of the first mode, the start time of the period of the first mode, and the end time of the period of the first mode.
[0083] Taking the configuration information carrying the activation time information of the first mode as an example, in some implementations, the activation time information of the first mode is used to indicate the start activation time of the first mode and / or the duration of the activation time of the first mode.
[0084] In some implementations, the activation time of the first mode can be indicated by a time offset from the start activation time of the first mode. This time offset can be understood as the time difference between the start activation time of the first mode and a reference time.
[0085] In some scenarios, the time offset of the start activation time of the first mode can be represented as "OnStartOffset". Taking deepCellDTX / DRX as an example, the time offset of the start activation time of the first mode can be represented as "deepCellDTX / DRX - OnStartOffset". Taking deepCellDTX as an example, the time offset of the start activation time of the first mode can be represented as "deepCellDTX - OnStartOffset". Taking deepCellDRX as an example, the time offset of the start activation time of the first mode can be represented as "deepCellDRX - OnStartOffset".
[0086] In this embodiment, the reference time is not limited. In some implementations, the reference time may be the time when the terminal device receives the configuration information. Of course, in this embodiment, the reference time may be the time agreed upon by a protocol or configured by the network device.
[0087] Taking the configuration information used to configure the activation time information of the first mode in the neighboring cell as an example, in some implementations, the activation time information of the first mode in the neighboring cell is used to indicate the start activation time and / or the duration of the activation time of the first mode in the neighboring cell.
[0088] In some implementations, the activation time of the first mode in a neighboring cell can be indicated by a time offset from the start activation time of the first mode in the neighboring cell. This time offset can be understood as the time difference between the start activation time of the first mode in the neighboring cell and a reference time.
[0089] In this application embodiment, the reference time is not limited. In some implementations, the reference time may be the time when the terminal device receives configuration information. Of course, in this application embodiment, the reference time may be the time agreed upon by a protocol or configured by the network device. Furthermore, it should be noted that the reference time used to determine the activation time of the first mode in a neighboring cell may be the same as the reference time used to determine the activation time of the first mode in the current cell (e.g., the first cell), which helps reduce the overhead of configuration information. Of course, in this application embodiment, the reference time used to determine the activation time of the first mode in a neighboring cell may be different from the reference time used to determine the activation time of the first mode in the current cell (e.g., the first cell), which helps improve the flexibility of indicating the activation time of the first mode in both neighboring and current cells.
[0090] Taking the configuration information used to indicate the inactivity time information of the first mode as an example, in some implementations, the inactivity time information of the first mode is used to indicate the start inactivity time of the first mode and / or the duration of the inactivity time of the first mode.
[0091] In some implementations, the inactivity time of the first mode can be indicated by a time offset that indicates the start inactivity time of the first mode. This time offset can be understood as the time offset between the start inactivity time of the first mode and a reference time.
[0092] In some scenarios, the time offset of the initial inactivity time of the first mode can be expressed as "OffStartOffset". Taking deepCellDTX / DRX as an example, the time offset of the initial inactivity time of the first mode can be expressed as "deepCellDTX / DRX - OffStartOffset". Taking deepCellDTX as an example, the time offset of the initial inactivity time of the first mode can be expressed as "deepCellDTX - OffStartOffset". Taking deepCellDRX as an example, the time offset of the initial activation time of the first mode can be expressed as "deepCellDRX - OffStartOffset".
[0093] In this embodiment, the reference time is not limited. In some implementations, the reference time may be the time when the terminal device receives the configuration information. Of course, in this embodiment, the reference time may be the time agreed upon by a protocol or configured by the network device.
[0094] It should be noted that the first mode may include Deep Cell DTX / DRX, Deep Cell DRX, and Deep Cell DTX. Correspondingly, the configuration information for these different modes can be independent of each other. That is, the configuration information may include configuration information for Deep Cell DTX / DRX, configuration information for Deep Cell DRX, and configuration information for Deep Cell DTX. Of course, in this embodiment, the configuration information for different modes can be contained within the same configuration information, or in other words, the configuration information for different modes can share a single set.
[0095] Furthermore, in this embodiment, the above configuration information can be applied to both the configuration information for the first mode of neighboring cells and the configuration information for the first mode of the current cell (the first cell). That is, the parameters related to the first mode in the above configuration information can include parameters related to the first mode in neighboring cells and / or parameters related to the first mode in the first cell.
[0096] The configuration information in the embodiments of this application has been described above. The transmission method of the configuration information in the embodiments of this application is described below. In some implementations, the configuration information can be carried in system messages and / or RRC messages, wherein the RRC message can be one or more of the following: RRC reconfiguration message, RRC recovery message, and RRC release message.
[0097] The first mode and its configuration process in this application embodiment have been introduced above. The deactivation scheme of the first mode in this application embodiment is described below. In this application embodiment, the deactivation scheme of the first mode can be divided into two methods: the terminal device actively requests to deactivate the first mode, and the network device instructs to deactivate the first mode. The following describes the methods in conjunction with implementation method 1 and implementation method 2 respectively.
[0098] It should be noted that in this embodiment, deactivating the first mode can be understood as exiting the first mode, meaning that the first cell no longer communicates with the terminal device based on the first mode. In other words, deactivating the first mode has a different meaning from the inactive time when entering the first mode.
[0099] Implementation Method 1: The terminal device actively requests to activate or deactivate the first mode, or in other words, the terminal device requests to activate or deactivate the first mode on demand.
[0100] In other words, the above method further includes: the terminal device sending a second request to the first cell, the second request being used to request activation or deactivation of the first mode. In this embodiment, the terminal device can request activation or deactivation of the first mode based on its own situation (e.g., its own mobility situation or service situation), so that the network device can better serve the terminal device.
[0101] In some implementations, assuming the second request is used to request deactivation of the first mode, the terminal device sending the second request to the first cell includes: if the second condition is met, the terminal device sends the second request to the first cell. That is to say, the second request can be triggered based on the second condition.
[0102] In some implementations, the second condition is associated with one or more of the following: the measurement value of the first cell; the moving speed of the terminal device; the number of times the terminal device performs cell reselection.
[0103] Taking the association of the second condition with the measurement value of the first cell as an example, in some implementations, the second condition includes that the measurement value of the first cell is lower than the measurement reference value of the first cell, and the difference between the measurement value of the first cell and the measurement reference value of the first cell is greater than a sixth threshold. Of course, in the embodiments of this application, the second condition may include that the measurement value of the first cell is lower than the measurement reference value of the first cell. The sixth threshold may be determined based on one or more of the following: predefined information, preconfiguration information, or configuration information sent by the network device.
[0104] In the embodiments of this application, the measured values are not limited. In some implementations, the measured values can be used to indicate signal quality. For example, the measured values may include one or more of the following: RSRQ, RSRP, and SINR.
[0105] For example, the measurement value of the first cell is represented as S. rxlev The measurement reference value for the first cell is denoted as S. rxlevRef The sixth threshold is represented by S. T, Accordingly, the second condition is that within time period T2, S rxlevRef –S rxlev T If the second condition is met, the terminal device sends a second request to the first cell to request deactivation of the first mode.
[0106] In this embodiment of the application, if the second condition is met, it indicates that the communication quality of the first cell is poor. At this time, the terminal device sends a second request to the first cell to request the deactivation of the first mode so that the terminal device and the first cell can resume communication as soon as possible, which helps to improve the communication quality between the first cell and the terminal device.
[0107] Taking the second condition as an example of being associated with the moving speed of the terminal device, in some implementations, the second condition includes the moving speed of the terminal device being higher than a fourth threshold, wherein the fourth threshold can be determined based on one or more of the following: predefined information, preconfiguration information, or configuration information sent by the network device.
[0108] In this embodiment of the application, if the second condition is met, it indicates that the terminal device is moving at a relatively fast speed. At this time, if the first cell is still in the first mode, it may cause the communication quality between the terminal device and the first cell to decrease. At this time, the terminal device sends a second request to the first cell to request the deactivation of the first mode, which helps to ensure the communication quality between the first cell and the terminal device.
[0109] Taking the association of the second condition with the number of times the terminal device performs cell reselection as an example, in some implementations, the second condition includes the number of times the terminal device performs cell reselection within a first time period exceeding a fifth threshold. Of course, in the embodiments of this application, the second condition may also include the number of times the terminal device performs cell reselection exceeding a fifth threshold. The first time period and / or the fifth threshold can be determined based on one or more of the following: predefined information, preconfiguration information, or configuration information sent by the network device.
[0110] In this embodiment of the application, if the second condition is met, it means that the terminal device has performed cell reselection a large number of times. At this time, if the first cell is still in the first mode, it may cause the communication quality between the terminal device and the first cell to degrade. At this time, the terminal device sends a second request to the first cell to request deactivation of the first mode, which helps to ensure the communication quality between the first cell and the terminal device.
[0111] It should be noted that the second conditions described above in the embodiments of this application can be used individually or in combination. For example, the second condition may include the terminal device's moving speed being higher than a fourth threshold, and the terminal device performing cell reselection more than a fifth threshold within a first time period. Another example is that the second condition may include the terminal device's moving speed being higher than a fourth threshold, and the measured value of the first cell being lower than the measured reference value of the first cell, and the difference between the measured value of the first cell and the measured reference value of the first cell being greater than a sixth threshold. Yet another example is that the second condition may include the terminal device performing cell reselection more than a fifth threshold within a first time period, and the measured value of the first cell being lower than the measured reference value of the first cell, and the difference between the measured value of the first cell and the measured reference value of the first cell being greater than a sixth threshold. Yet another example is that the second condition may include the terminal device's moving speed being higher than a fourth threshold, and the terminal device performing cell reselection more than a fifth threshold within a first time period, and the measured value of the first cell being lower than the measured reference value of the first cell, and the difference between the measured value of the first cell and the measured reference value of the first cell being greater than a sixth threshold.
[0112] In some implementations, it is assumed that the first mode includes Deep Cell DRX and / or Deep Cell DTX / DRX. If the second condition is met, the first cell is within the activation time of the first mode. At this time, the terminal device can directly send the second request to the first cell.
[0113] In some other implementations, assuming the first mode includes Deep Cell DRX and / or Deep Cell DTX / DRX, if the second condition is met, the first cell is in the inactive time of the first mode. At this time, the terminal device can wait until the activation time of the first mode is entered before sending a second request to the first cell.
[0114] In some implementations, the second request can be carried on a WUS signal, which can be, for example, a preamble, an uplink LP-WUS, or Msg3 during the RA process.
[0115] In some implementations, if the terminal device sends a second request, but the first cell has not deactivated the first mode, the terminal device can perform cell reselection. That is, the above method also includes: if the first cell has not deactivated the first mode, the terminal device performs cell reselection. For an introduction to cell reselection, please see below.
[0116] In this embodiment, the method for confirming that the first cell has not deactivated the first mode is not limited. In some implementations, if the terminal device does not receive confirmation information for deactivating the first mode within a certain period after sending the second request, it can be determined that the first cell has not deactivated the first mode, and the terminal device can perform cell reselection. For example, the terminal device can run timer 1 while sending the second request. Accordingly, if timer 1 expires and the terminal device still has not received confirmation information for deactivating the first mode, it can be determined that the first cell has not deactivated the first mode, and the terminal device can perform cell reselection.
[0117] Implementation method 2: The network device instructs the activation of the first mode.
[0118] In some implementations, the above method further includes: the first cell sending first indication information to the terminal device, the first indication information being used to indicate activation or deactivation of the first mode.
[0119] In some implementations, the first indication information is carried in a system message change message and / or an RRC reconfiguration message. For example, assuming the first indication information is carried in a system message change message, the terminal device, after receiving the system message change message, can continue to receive new configuration information for the first mode and apply the new configuration information during the next system message modification. As another example, assuming the terminal device is in a connected state, the first indication information can be carried in an RRC reconfiguration message. Of course, in the embodiments of this application, the first indication information can also be carried in a medium access control element (MAC CE) and / or downlink control information (DCI).
[0120] The above describes the activation or deactivation scheme of the first mode in the embodiments of this application. The following describes the neighbor cell measurement scheme based on the first mode in the embodiments of this application.
[0121] In some scenarios, terminal devices in a disconnected state may need to perform neighbor cell measurements to facilitate subsequent cell handover operations. In some implementations, the first mode includes a cell DTX mode, and the first cell is within the activation time of the first mode. The method further includes: the terminal device determining whether to perform measurements for the neighbor cell based on the activation time of the first mode in the neighbor cell.
[0122] In some implementations, the activation time of the first mode in the neighboring cell includes the remaining activation time of the first mode in the neighboring cell. The terminal device then determines whether to perform a measurement for the neighboring cell based on the activation time of the first mode in the neighboring cell, including: if the duration of the remaining activation time is greater than a first threshold, the terminal device determines to perform a measurement for the neighboring cell; and / or if the duration of the remaining activation time is less than or equal to the first threshold, the terminal device determines not to perform a measurement for the neighboring cell. The first threshold can be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.
[0123] In some implementations, the terminal device determines to perform measurements for neighboring cells, which can be replaced by the terminal device performing measurements for neighboring cells. In other implementations, the terminal device determines not to perform measurements for neighboring cells, which can be replaced by the terminal device not performing measurements for neighboring cells.
[0124] In this embodiment of the application, if the duration of the remaining activation time is greater than the first threshold, it means that the neighboring cell can continue to send downlink signals or downlink channels during the remaining activation time. At this time, the terminal device can perform measurements based on the downlink signals or downlink channels sent in the neighboring cell, which helps to reduce the latency of the terminal device performing neighboring cell measurements.
[0125] In addition, if the remaining activation time is less than or equal to the first threshold, it indicates that the time for the neighboring cell to send downlink signals or downlink channels is too short, which may not be enough for the terminal device to perform neighboring cell measurements based on downlink signals or downlink channels. In this case, the terminal device can determine not to perform measurements for the neighboring cell in order to improve the efficiency of neighboring cell measurements.
[0126] In some implementations, the terminal device determines whether to perform a measurement for the neighboring cell based on the activation time of the first mode in the neighboring cell, including: if the time interval between the activation time of the first mode in the neighboring cell and the current time is less than a first threshold, the terminal device determines to perform a measurement for the neighboring cell; and / or if the time interval between the activation time of the first mode in the neighboring cell and the current time is greater than or equal to the first threshold, the terminal device determines not to perform a measurement for the neighboring cell.
[0127] In some implementations, the time interval between the activation time of the first mode in the neighboring cell and the current time may include the time interval between the start activation time of the first mode and the current time. Of course, in this embodiment, the time interval between the activation time of the first mode and the current time may also be the time interval between the end activation time of the first mode and the current time.
[0128] In some implementations, the current time can be understood as the time when the terminal device prepares to determine whether to perform neighbor cell measurements.
[0129] In some implementations, the terminal device determines to perform measurements for neighboring cells, which can be replaced by the terminal device performing measurements for neighboring cells. In other implementations, the terminal device determines not to perform measurements for neighboring cells, which can be replaced by the terminal device not performing measurements for neighboring cells.
[0130] In this embodiment of the application, if the time interval is greater than the first threshold, it means that the neighboring cell needs to wait for a long time before it can enter the activation time of the first mode. That is to say, the terminal device needs to wait for a long time before it can receive downlink signals or downlink channels in the neighboring cell. At this time, the time delay required for the terminal device to perform neighboring cell measurement based on downlink signals or downlink channels is large. Therefore, the terminal device may not perform neighboring cell measurement.
[0131] In addition, if the time interval is less than or equal to the first threshold, it means that the neighboring cell is about to or has already entered the activation time of the first mode. That is to say, the terminal device needs to wait a short time to receive the downlink signal or downlink channel in the neighboring cell. At this time, the time delay required for the terminal device to perform neighboring cell measurement based on the downlink signal or downlink channel is small.
[0132] It should also be noted that there is usually a clear temporal relationship between the activation time of the first mode and the inactivation time of the first mode in the neighboring cell. Therefore, the above determination of whether to perform a measurement for the neighboring cell based on the activation time of the first mode in the neighboring cell can be understood as determining whether to perform a measurement for the neighboring cell based on the inactivation time of the first mode in the neighboring cell.
[0133] The preceding section introduced the neighbor cell measurement scheme based on the first mode in the embodiments of this application. The following section introduces the cell reselection scheme based on the first mode in the embodiments of this application. In some implementations, the above method further includes: the terminal device performing cell reselection.
[0134] In some implementations, the target cell for cell reselection satisfies one or more of the following: a cell that does not support the first mode; the target cell is active in the first mode; and the time interval between the cell reselection execution time and the target cell's active time in the first mode is less than a first threshold.
[0135] In some implementations, if the target cell for cell reselection does not support the first mode, it helps reduce the communication latency between the terminal device and the target cell compared to the terminal device reselecting to a target cell that supports the first mode. For example, if the terminal device has urgent uplink data to transmit, it can use cell reselection to access a target cell that does not support the first mode and send uplink data through the target cell, which helps reduce the latency of uplink data transmission.
[0136] In this embodiment, the method by which the terminal device determines whether the target cell supports the first mode is not limited. In some implementations, whether the target cell supports the first mode can be configured by the network device. For example, if the target cell is a neighboring cell, the network device can indicate whether the neighboring cell supports the first mode through the neighboring cell configuration information described above. For related information, please refer to the indication information for the first mode in the configuration information.
[0137] In some implementations, if the target cell for cell reselection is active during the first mode's activation time, it helps reduce the latency of the terminal device waiting to communicate with the target cell compared to reselecting a target cell that is inactive during the first mode's activation time. For example, if the first mode includes Deep Cell Redirection (DRX), and the terminal device has uplink data that needs to be transmitted urgently, the terminal device can use cell reselection to select a target cell that is active during the first mode's activation time. In this case, the terminal device can immediately send uplink data to the target cell during the first mode's activation time, which helps reduce the latency of uplink data transmission.
[0138] In some implementations, if the time interval between the target cell's reselection time and the target cell's activation time in the first mode is less than a first threshold, meaning the target cell immediately enters the first mode activation time, it helps reduce the latency of the terminal device waiting to communicate with the target cell. For example, if the first mode includes Deep Cell Replication (DRX), and the terminal device has uplink data to transmit urgently, the terminal device can use cell reselection to select a target cell that meets the above conditions. In this case, after the first time interval, it will enter the first mode activation time, and correspondingly, the terminal device can immediately send uplink data to the target cell, which helps reduce the latency of uplink data transmission.
[0139] In this embodiment, there is no limitation on how the terminal device obtains the activation time of the first mode of the target cell. In some implementations, the activation time of the first mode of the target cell can be configured by the network device. For example, if the target cell is a neighboring cell, the network device can configure the relevant parameters of the activation time of the first mode through the configuration information of the neighboring cells described above.
[0140] In some implementations, the aforementioned terminal device performs cell reselection by: if a first condition is met, the terminal device performs cell reselection. That is to say, cell reselection can be triggered by the first condition.
[0141] In some implementations, the first condition includes one or more of the following: the time interval between the current time and the activation time of the first mode is greater than a second threshold; the time interval between the current time and the first PO is greater than a third threshold.
[0142] Taking the first condition, which includes the time interval between the current time and the activation time of the first mode being greater than the second threshold, as an example, it means that the terminal device needs to wait for a long time before entering the activation time of the first mode. At this time, the terminal device can perform cell reselection, which helps to reduce the latency of the terminal device waiting to communicate with the first cell.
[0143] For example, the first mode includes Deep Cell DRX, and the time interval between the current time and the activation time of the first mode is greater than a second threshold. That is, the activation time of the first mode can only be entered after the above time interval, at which point the terminal device can send uplink data to the first cell. Assuming that the latency requirement for the uplink data to be sent by the terminal device is high, the terminal device can perform cell reselection to reduce the latency of uplink data transmission.
[0144] In this embodiment, the aforementioned time interval is not limited. In some implementations, the aforementioned time interval may refer to the time interval between the previous time and the start activation time of the first mode. Of course, in this embodiment, the aforementioned time interval may refer to the time interval between the current time and a certain moment in the activation time of the first mode.
[0145] In addition, the second threshold in this application embodiment can be determined based on one or more of the following: predefined information, preconfiguration information, or configuration information sent by the network device.
[0146] Taking the first condition, which includes the time interval between the current time and the first paging occasion (PO) being greater than the third threshold, as an example, it means that the terminal device needs to wait for a long time to get the first PO. At this time, the terminal device can perform cell reselection, which helps to reduce the latency of the terminal device waiting for the first PO.
[0147] In some implementations, the first PO is earlier than the other POs in the time domain. The other POs are the POs other than the first PO among the multiple POs corresponding to the terminal device. That is to say, the first PO can be the first PO among the POs corresponding to the terminal device. Of course, in the embodiments of this application, the first PO can also be one of the multiple POs corresponding to the terminal device.
[0148] In this application embodiment, the aforementioned time interval is not limited. In some implementations, the aforementioned time interval may refer to the time interval between the previous time and the start time of the first PO. Of course, in this application embodiment, the aforementioned time interval may refer to the time interval between the current time and a certain moment in the first PO.
[0149] In addition, the third threshold in this application embodiment can be determined based on one or more of the following: predefined information, preconfiguration information, or configuration information sent by the network device.
[0150] It should be noted that the above only exemplarily lists the first condition of the embodiments of this application. In some implementations, the first condition also includes a time interval between the current time and the first random access occasion (RO) greater than a threshold. That is, the terminal device needs to wait for a relatively long time before the first RO. At this time, if the terminal device has urgent services or uplink data to be transmitted, the terminal device can perform cell reselection, which helps to reduce transmission latency. In addition, in the embodiments of this application, the first conditions described above can be used independently or in combination.
[0151] As the types of terminal devices introduced into communication systems increase, and these different types of terminal devices have different capabilities, in order to improve the efficiency of network equipment configuring the first mode for terminal devices, the terminal device can send capability information to the first cell to indicate whether the terminal device supports the first mode, so that the first cell can configure it based on the terminal device's capability information.
[0152] In some implementations, the above method further includes: the terminal device sending capability information to the first cell, the capability information being used to indicate whether the terminal device supports the first mode.
[0153] Taking the first mode, which includes Deep Cell DRX, as an example, the capability information is used to indicate whether the terminal device supports Deep Cell DRX.
[0154] Taking the first mode, which includes Deep Cell DTX, as an example, the capability information is used to indicate whether the terminal device supports Deep Cell DTX.
[0155] Taking the first mode, which includes Deep Cell DTX / DRX, as an example, the capability information is used to indicate whether the terminal device supports Deep Cell DTX / DRX.
[0156] In some implementations, capability information is carried in RRC messages and / or UE capability reporting messages. The radio resource control (RRC) messages may include one or more of the following: RRC Resume Complete, RRC Setup Complete, and RRC Reestablishment Complete.
[0157] In some implementations, the aforementioned capability information may be requested by the first cell from the terminal device. That is, the method further includes: the terminal device receiving a first request sent by the first cell, the first request being used to request the terminal device's capability information. Of course, in this embodiment, the aforementioned capability information may be actively reported by the terminal device to the first cell. For example, the terminal device may periodically report capability information to the first cell.
[0158] In some implementations, in order for network devices to prevent terminal devices that do not support the first mode from residing in cells that support the first mode, the first cell can send a second indication message to the terminal device of that type. That is, the method further includes: the first cell sending a second indication message to the terminal device, the second indication message being used to instruct the terminal device to prohibit access to the first cell, and / or the reason for prohibiting the terminal device from accessing the first cell including that the first cell is in the first mode (or, in other words, the first cell supports the first mode).
[0159] For example, the second indication information could be a cell access prohibition indication associated with the first mode in the system information block (SIB) of the first cell. That is to say, the cell access prohibition indication could be specifically set for the first mode.
[0160] In some implementations, cell access prohibition indications associated with the first mode have a higher priority than traditional cell access prohibition indications (i.e., cell access prohibition indications unrelated to the first mode). Accordingly, the terminal device can preferentially select the cell to access based on the cell access prohibition indication associated with the first mode.
[0161] The wireless communication method of this application embodiment is described below with reference to Figures 3 and 4. It should be understood that Figures 3 and 4 mainly illustrate the method flow, and the terminology and related details involved in the method flow can be found in the above description.
[0162] The scheme shown in Figure 3 assumes that the first mode includes deep cell DTX and / or deep cell DTX / DRX, and the method shown in Figure 3 includes steps S310 to S350.
[0163] In step S310, the terminal device sends capability information to the network device of the first cell.
[0164] In some implementations, capability information is used to indicate whether the terminal device supports Deep Cell DTX, Deep Cell DRX, or Deep Cell DTX / DRX.
[0165] In step S320, if the terminal device supports Deep Cell DTX and / or Deep Cell DTX / DRX, the network device of the first cell sends the configuration information of the first mode to the terminal device.
[0166] In some implementations, the configuration information carries one or more of the following: indication information for the first mode; activation indication information for the first mode; periodic information for the first mode; activation time information for the first mode; activation time information for the first mode in neighboring cells; and inactivity time information for the first mode. See the above for related information.
[0167] In step S330, if the first mode is activated, the terminal device determines the start time of onDurationTimer or the start time of offDurationTimer. For details on the start time of onDurationTimer or the start time of offDurationTimer, please refer to the above text.
[0168] In step S340, the terminal device and the first cell perform corresponding operations based on onDurationTimer or offDurationTimer.
[0169] In some implementations, the terminal device performs normal RACH operations while onDurationTimer is running or offDurationTimer is not running.
[0170] In some implementations, when the offDurationTimer is running or the onDurationTimer is not running, the terminal device's behavior includes one or more of the following: the terminal device does not perform paging message listening; the terminal device does not perform PEI listening; the terminal device does not perform LP-WUS listening; the terminal device does not perform SSB-based measurements and maintains the original SSB measurement results (when the terminal device's movement speed is relatively slow); the terminal device does not perform LP-SS-based measurements; the terminal device maintains the received system broadcast information and does not receive system broadcast information; the terminal device determines the start activation time of the first mode in the neighboring cell.
[0171] In some implementations, when the offDurationTimer is running or the onDurationTimer is not running, the first cell does not send downlink signals such as SSB, system broadcast, and paging messages during the inactive time of the first mode.
[0172] In some implementations, the offDurationTimer / onDurationTimer continues to run even when the terminal device transitions from a connected state to an idle state or an inactive state during the operation of offDurationTimer / onDurationTimer.
[0173] In step S350, if the first condition is met, the terminal device performs cell reselection.
[0174] In some implementations, the first condition may include a time interval between the current time and the activation time of the first mode that is greater than a second threshold; and / or a time interval between the current time and the first PO that is greater than a third threshold, wherein the first PO is earlier than other POs in the time domain, and the other POs are the POs other than the first PO among the multiple POs corresponding to the terminal device. See the above for related information.
[0175] In some implementations, the target cell for cell reselection satisfies one or more of the following conditions: it is a cell that does not support the first mode; the target cell is active in the first mode; and the time interval between the cell reselection execution time and the target cell's active time in the first mode is less than a first threshold. See the above for related information.
[0176] The scheme shown in Figure 4 assumes that the first mode includes deep cell DRX and / or deep cell DTX / DRX, and the method shown in Figure 4 includes steps S410 to S450.
[0177] In step S410, the terminal device sends capability information to the network device of the first cell.
[0178] In some implementations, capability information is used to indicate whether the terminal device supports Deep Cell DTX, Deep Cell DRX, or Deep Cell DTX / DRX.
[0179] In step S420, if the terminal device supports Deep Cell DTX and / or Deep Cell DTX / DRX, the network device of the first cell sends the configuration information of the first mode to the terminal device.
[0180] In some implementations, the configuration information carries one or more of the following: indication information for the first mode; activation indication information for the first mode; periodic information for the first mode; activation time information for the first mode; activation time information for the first mode in neighboring cells; and inactivity time information for the first mode. See the above for related information.
[0181] In step S430, if the first mode is activated, the terminal device determines the start time of onDurationTimer or the start time of offDurationTimer. For details on the start time of onDurationTimer or the start time of offDurationTimer, please refer to the above text.
[0182] In step S440, the terminal device and the first cell perform corresponding operations based on onDurationTimer or offDurationTimer.
