As shown in FIG. 2, which is a schematic flow chart of a communication method 200 provided in an exemplary embodiment of the present application, the method 200 can, but is not limited to, be executed by a network device, and specifically can be executed by hardware and/or software installed in the network device. In this embodiment, the method 200 can at least comprise the following steps.

S210, first information is sent.

Wherein the first information is used to instruct or configure at least one of the following (11)-(13).

(11) Sending a paging message by a secondary carrier or a secondary cell.

It is to be understood that, as for (11), in this embodiment, for a cell that is covered by multiple carriers (such as carrier F1, carrier F2), a primary carrier or a primary cell needs to send reference signals (such as synchronization signal and PBCH block (SSB), channel state information-reference signal (CSI-RS), etc.), system information (such as system information of a secondary carrier or a secondary cell, etc.), paging messages, etc., whereas a secondary carrier or a secondary cell does not send reference signals, system information, a paging messages, etc. Therefore, taking into account the heavy paging load of a primary carrier or a primary cell, in this embodiment, paging messages are sent by a secondary carrier or a secondary cell, which can prevent the primary carrier or the primary cell from sending paging messages, as a result, the silence time of the primary carrier or the primary cell is extended and the energy consumption of the network device (such as a base station) is reduced.

(12) The network device stopping receiving uplink transmission.

(13) The network device stopping sending downlink transmission.

It is to be understood that, in one implementation, in addition to instructing or configuring the aforementioned (11)-(13), the first information can further instruct whether the network device is in a silence or energy-saving state, a beginning time when the network device is in a silence or energy-saving state, an ending time when the network device is in a silence or energy-saving state, a duration when the network device is in a silence or energy-saving state, etc., which is not limited by this embodiment.

In addition, in this embodiment, by means of sending first information and a terminal receiving the first information, behaviors between the network device and the terminal can be aligned, such that the terminal and the network device understand silence or energy-saving behaviors of the network device in a consistent manner, which prevents the terminal from performing meaningless signal monitoring and/or sending behaviors while the network device is in a silence or energy-saving state (i.e., sending paging messages by a secondary carrier or a secondary cell, stopping receiving uplink transmission or stopping sending downlink transmission), at the same time, energy consumption of the terminal and the network device is reduced.

In addition, it should be noted that, other than sending the first information, the network device can further perform operations such as sending a paging message by a secondary carrier or a secondary cell, stopping receiving uplink transmission, and stopping sending downlink transmission, so that the network device itself enters a silence or energy-saving state, thereby resulting in reduction in energy consumption. It should be noted that, in this embodiment, there are no specific orders between the operation the network device sends first information and operations such as sending a paging message by a secondary carrier or a secondary cell, stopping receiving uplink transmission, and stopping sending downlink transmission, etc. For example, the network device sends first information at first, followed by sending a paging message by a secondary carrier or a secondary cell, stopping receiving uplink transmission, and stopping sending downlink transmission; alternatively, sending a paging message by a secondary carrier or a secondary cell, stopping receiving uplink transmission, stopping sending downlink transmission at first, and then the network device sends first information, which is not limited here.

In this embodiment, the network device, by sending first information, instructs or configures any one of the following: sending a paging message by a secondary cell or a secondary carrier, the network device stopping receiving uplink transmission, and the network device stopping sending downlink transmission. Therefore, the terminal is prevented from performing meaningless signal monitoring and/or sending behaviors while the network device is in silence or energy-saving state (i.e., sending a paging message by a secondary carrier or a secondary cell, stopping receiving uplink transmission or stopping sending downlink transmission), at the same time, energy consumption of the terminal and the network device is reduced.

As shown in FIG. 3, which is a schematic flow chart of a communication method 300 provided in an exemplary embodiment of the present application, the method 300 can, but is not limited to, be executed by a network device, and specifically can be executed by hardware and/or software installed in the network device. In this embodiment, the method 300 can at least comprise the following steps.

S310, first information is sent.

Wherein the first information is used to instruct or configure at least one of the following (21)-(23).

(21) Sending a paging message by a secondary carrier or a secondary cell.

(22) The network device stopping receiving uplink transmission.

(23) The network device stopping sending downlink transmission.

It is to be understood that, for the implementation process of the aforementioned (21)-(23), reference can be made to relevant description in the aforementioned method embodiment 200, in order to implement the aforementioned content that is instructed or configured by the first information, in one implementation, the first information can comprise at least one of the following (31)-(37).

(31) First instruction information for instructing the secondary carrier or the secondary cell to send a paging message.

(32) Second instruction information for instructing a terminal to monitor a paging message on the secondary carrier or the secondary cell.

For example, for the aforementioned (31) and (32), the network device can send (such as broadcast) or configure an enabling-or-not instruction (i.e., first instruction information or second instruction information) by a primary carrier or a primary cell, if it is an enabling instruction, then the network device sends a paging message by a secondary carrier or a secondary cell. Alternatively, a primary carrier or a primary cell broadcasts or configures an enabling-or-not instruction (i.e., first instruction information or second instruction information), and the instruction is associated with a secondary carrier or a secondary cell, if it is an enabling instruction, the network device can send a paging message by the associated secondary carrier or secondary cell. Correspondingly, for a terminal, if the network device broadcasts or configures that a secondary carrier or a secondary cell has a paging capability, the terminal can choose to monitor a paging message on the secondary carrier or the secondary cell.

It should be noted that, the aforementioned first instruction information or second instruction information can be an explicit instruction or an implicit instruction, which is not limited here.

(33) Paging resource configuration information corresponding to the secondary carrier or the secondary cell.

For example, the paging resource configuration information can comprise configuration information of physical downlink control channel (PDCCH) for paging, such as frequency-domain resource or time-domain resource of the PDCCH. Based on this, at a paging moment of a secondary carrier or a secondary cell, a terminal can monitor a paging message on the frequency-domain resource of the secondary carrier or the secondary cell, that is, if the network device instructs or configures paging resource configuration information corresponding to the secondary carrier or the secondary cell, the terminal can choose to receive the paging message on the secondary carrier or the secondary cell.

(34) Time information of the paging message monitored by the terminal on the secondary carrier or the secondary cell.

In one implementation, the time information of the paging message monitored by the terminal on the secondary carrier or the secondary cell can comprise: beginning time, period, duration, ending time, etc., of the paging message monitored by the terminal on the secondary carrier or the secondary cell.

(35) Configuration information of secondary carriers or secondary cells that have the same spatial characteristics as those of a primary carrier or a primary cell.

For example, assuming that the spatial characteristic is Quasi co-location (QCL), the network device broadcasts or configures frequency points of some carriers by a primary carrier or a primary cell, and the SSB of the primary carrier or the primary cell has the same QCL relationship as that of these secondary carriers or the secondary cells; alternatively, a primary carrier or a primary cell broadcasts or configures paging resource configuration of some secondary carriers or secondary cells, and the SSB resource of the primary carrier or the primary cell has the same QCL relationship as that of the paging resource. Based on this, if the network device broadcasts or configures some secondary carriers or secondary cells to have the same QCL relationship as that of the primary carrier or the primary cell, it can be determined by the terminal that, by measuring a reference signal of the primary carrier or the primary cell, the QCL relationship between the beam on the secondary carriers or the secondary cells and the paging resource can be obtained.

(36) Time information of the network device stopping receiving uplink transmission.

In one implementation, the time information of the network device stopping receiving uplink transmission comprises at least one of beginning time, ending time, duration, and period of the network device stopping receiving uplink transmission.

(37) Time information of the network device stopping sending downlink transmission.

In one implementation, the time information of the network device stopping sending downlink transmission comprises at least one of beginning time, ending time, duration, and period of the network device stopping sending downlink transmission.

In addition, in another implementation, when a network-side device sends first information, the first information is sent (such as broadcast) by a primary carrier or a primary cell, therefore, at least one of the following conditions (41)-(43) is met.

(41) The first information instructs sending-priority information of a paging message on the secondary carrier or the secondary cell.

In one implementation, the sending-priority of a paging message on the secondary carrier or the secondary cell comprises: the priority of a reference signal of a primary carrier or a primary cell is higher than the priority of a paging message of a secondary carrier or a secondary cell; alternatively, the priority of system information of a primary carrier or a primary cell is lower than the priority of a paging message of a secondary carrier or a secondary cell.

For example, if a network device broadcasts or configures resource of a secondary carrier or a secondary cell that is used for paging by a primary carrier or a primary cell, it can be determined by the terminal that, at the time when a reference signal of the primary carrier or the primary cell is sent, the secondary carrier or the secondary cell will not send a paging message; alternatively, the priority of the reference signal of the primary carrier or the primary cell is higher than that of the paging message of the secondary carrier or the secondary cell; alternatively, at the time when a paging message of the secondary carrier or the secondary cell is sent, the primary carrier or the primary cell will not send system information; alternatively, the priority of paging moment of the secondary carrier or the secondary cell is higher than that of system information of the primary carrier or the primary cell.

(42) A primary carrier or a primary cell meets cell residency conditions, that is, the terminal can reside in a secondary carrier or a secondary cell, so as to enable the sending of a paging message, etc., on the secondary carrier or the secondary cell.

(43) A primary carrier or a primary cell meets an S criterion for cell reselection, that is, a terminal can reside in a secondary carrier or a secondary cell, so as to enable the sending of a paging message, etc., on the secondary carrier or the secondary cell.

Based on the aforementioned description, as one possible implementation, when a terminal receives first information, and the first information instructs or configures at least one of: sending a paging message by a secondary carrier or a secondary cell, a network device stopping sending downlink transmission, and the network device stopping receiving uplink transmission (that is, the network device stops scheduling and sending signals), if a terminal continues monitoring a paging message by a primary carrier or a primary cell, continues monitoring downlink transmission and sending uplink transmission, etc., then the aforementioned behaviors performed by the terminal are meaningless and will result in unnecessary terminal energy-consumption. In this regard, in this embodiment, in order to align behaviors of the network device and the terminal as well as to reduce terminal energy-consumption, the terminal can perform, after receiving the first information, at least one of the following (51)-(58) according to the first information.

(51) When in an idle state or inactive state, reside in or reselect to the secondary carrier or the secondary cell, and monitor a paging message on the secondary carrier or the secondary cell. For example, the terminal can reside in or reselect to the secondary carrier or the secondary cell, and monitor a paging message on the secondary carrier or the secondary cell according to the following: the paging resource configuration information corresponding to the secondary carrier or the secondary cell; the time information of a paging message monitored by the terminal on the secondary carrier or the secondary cell; first instruction information; and second instruction information; etc.

It should be noted that, when the terminal resides in or reselects to the secondary carrier or the secondary cell, it can reside in or reselect to the secondary carrier or the secondary cell according to a terminal identifier. For example, for a primary carrier or a primary cell and a secondary carrier or a secondary cell that is configured with paging configuration, the terminal can select a secondary carrier or a secondary cell to reside in or reselect to according to a terminal identifier (that is, the number of UE identifier mod carriers). For example, there is a primary carrier or a primary cell and N−1 secondary carriers or secondary cells (indexed 1, . . . , N−1), and each secondary carrier or secondary cell corresponds to an index, then the carrier for the terminal to reside in is selected according to the result of (UE identifier mod N), if the result is 0, the primary carrier or the primary cell is selected; if it is not zero, the secondary carrier or the secondary cell corresponding to the index is selected according to the result.

In addition, when the terminal is in an idle state or an inactive state, other than residing in or reselecting to the secondary carrier or the secondary cell according to a terminal identifier, the terminal can also reside in or reselect to the secondary carrier or the secondary cell according to second information sent by the network device. This can be understood as follows: taking into account that the network device sends a paging message by a secondary carrier or a secondary cell, correspondingly, when the terminal is in an idle state or an inactive state and/or when the terminal determines that the present time is a paging moment, the terminal needs to reside in the secondary carrier or the secondary cell so as to monitor a paging message. In this regard, in this embodiment, in order to achieve the purpose of the terminal residing in the secondary carrier or the secondary cell so as to monitor a paging message, the second information can be sent, and the second information is used to instruct or configure at least one of the following (a)-(c).

• • (a) The secondary carrier or the secondary cell supports the terminal for residing in.
  • (b) The secondary carrier or the secondary cell supports the terminal for cell reselection.
  • (c) The secondary carrier or the secondary cell supports itself as a candidate cell.

For example, for instructions of the aforementioned (a)-(c), an enabling-or-not instruction (i.e., second information) can be broadcast or configured by a primary carrier or a primary cell, and the instruction is associated with a secondary carrier or a secondary cell. If it is an enabling instruction, it is determined by the terminal that the secondary carrier or the secondary cell is available for residing in and can be used as a candidate cell during cell reselection.

It should be noted that, in this embodiment, the second information can be an explicit instruction or an implicit instruction when implementing the aforementioned information instruction. For example, when the second information is an implicit instruction, the second information comprises the paging configuration information of the secondary carrier or the secondary cell, and/or the reference signal configuration information of the secondary carrier or the secondary cell. For example, when the second information comprises the paging configuration information of the secondary carrier or the secondary cell and/or the reference signal configuration information of the secondary carrier or the secondary cell, it can be determined by the terminal that the secondary carrier or the secondary cell is available for residing in and can be used as a candidate cell during cell reselection.

It is to be understood that, when the network device sends the second information, at least one of the following is met: the first information instructs on sending-priority information of a paging message on the secondary carrier or the secondary cell; the primary carrier or the primary cell meets cell residence conditions; the primary carrier or the primary cell meets the S criterion for cell reselection. Regarding the aforementioned content, please refer to relevant description in (41)-(43) above, this will not be repeated here.

(52) Stop monitoring downlink transmission (such as PDCCH, etc.) within the first time.

It is to be understood that, the first time mentioned in this embodiment can be considered as silence time or energy-saving time and the like of a network device. The first time can be determined according to the time information of the network device stopping receiving uplink transmission and/or the time information of the network device stopping sending downlink transmission, for example, the first time is the same as the time information of the network device stopping receiving uplink transmission and/or the time information of the network device stopping sending downlink transmission.

In one implementation, after receiving the first information, the first time can be considered by the terminal that as inactive time of discontinuous reception (DRX), and the terminal can stop monitoring downlink transmission during running time of a first timer. The starting time of the first timer is determined according to the network device stopping sending time information of downlink transmission, for example, the first timer is started at beginning moment when the network device stops sending downlink transmission. Running time (or duration) of the first timer is associated with the first time, for example, the running time of the first timer is the same as the first time.

In another implementation, when the downlink transmission is designated downlink transmission, at beginning moment of the first time, a second timer or response window corresponding to the designated downlink transmission is stopped, and at ending time of the first time, a second timer or response window corresponding to the designated downlink transmission is started. Optionally, when the designated downlink transmission is PDCCH corresponding to random access response (RAR), the second timer or response window comprises random access (RA)-response window (RA-ResponseWindow) and/or RA-ContentionResolutionTimer; when the designated downlink transmission is PDCCH corresponding to preconfigured uplink resource (PUR), the second timer or response window comprises PUR-ResponseWindow and/or PUR-timer; when the designated downlink transmission is PDCCH corresponding to Message 3 (msg3), the second timer or response window comprises msgB-Response Window.

For example, at beginning moment of the first time, ra-ResponseWindow, ra-ContentionResolutionTimer, msgB-ResponseWindow, and PUR-ResponseWindow timers are stopped by the terminal; and at ending time of the first time, ra-ResponseWindow, ra-ContentionResolutionTimer, msgB-ResponseWindow, and PUR-ResponseWindow timers are started by the terminal.

Further, in order to increase a probability of successful monitoring, when the monitoring time corresponding to the designated downlink transmission overlaps with the first time, the duration of the second timer or response window corresponding to the designated downlink transmission can be extended by the first time.

For example, assuming that the monitoring time corresponding to the designated downlink transmission overlaps with the first time, the second timer or response window is ra-Response Window, ra-ContentionResolution Timer, msgB-ResponseWindow, PUR-Response Window, and the duration of ra-Response Window, ra-ContentionResolutionTimer, msgB-ResponseWindow, PUR-ResponseWindow is T, the first time is N, then the extended duration of ra-ResponseWindow, ra-ContentionResolutionTimer, msgB-ResponseWindow, PUR-Response Window is T+N.

(53) Stop measuring reference signals, such as SSB, CSI-RS, etc., within the first time.

(54) Stop the wireless-link monitoring of reference signals within the first time.

In one implementation, in order to reduce the probability of radio link failure, if one or more reference signals cannot be sent during an evaluation period of a radio link, the evaluation period of the radio link will be increased by periods of the one or more reference signals. In other words, if at least one reference signal is not sent during an evaluation period of the radio link, the number of evaluation periods of the radio link will be increased, or the evaluation period of the radio link will be extended by the first time.

For example, an evaluation period of a wireless link is T, the first time comprises M reference signals, and a period of a reference signal is N, then the extended evaluation period of the wireless link will be T+M*N.

For example, if one or more reference signals cannot be sent during an evaluation period of a radio link, the evaluation period of the radio link will be extended by the first time. For example, an evaluation period of a wireless link is T, the duration of the first time is N, then the extended evaluation period of the wireless link will be T+N.

(55) Stop performing beam-failure detection or link-recovery detection on a reference signal within the first time.

In one implementation, in order to reduce the probability of beam failure, if one or more reference signals cannot be sent during an evaluation period of beam-failure detection or link-recovery detection, the evaluation period will be increased by periods of the one or more reference signals. In other words, if at least one reference signal is not sent during an evaluation period of beam-failure detection or link-recovery detection, the number of evaluation periods of beam-failure detection or link-recovery detection will be increased, or the evaluation period of beam-failure detection or link-recovery detection will be extended by the first time.

For example, assuming that an evaluation period is T, the first time comprises M reference signals, and a period of a reference signal is N, then the extended evaluation period will be T+M*N.

For example, if one or more reference signals cannot be sent during an evaluation period, the evaluation period of the radio link will be extended by a duration of the first time. For example, if an evaluation period is T, a duration of the first time is N, then the extended evaluation period will be T+N.

(56) Stop sending uplink transmission, such as Physical Uplink Shared Channel (PUSCH), Physical Random Access Channel (PRACH), Sounding Reference Signal (SRS), Scheduling Request (SR), etc., within the first time.

In one implementation, during the running time of a third timer, sending uplink transmission, such as PUSCH, PRACH, SRS, SR, etc., is stopped. The starting time of the third timer is determined according to the time information of the network device stopping receiving uplink transmission, and the duration of the third timer is associated with the first time. In other words, the terminal can start a third timer at beginning moment of the first time, then the terminal stops sending uplink transmission during the running time of the third timer.

In another implementation, when the uplink transmission is designated uplink transmission (such as SR, etc.) and the running time of a fourth timer corresponding to the designated uplink transmission overlaps (or partially overlaps) with the first time, the running time of the fourth timer is extended by the first time; alternatively, the running time of the fourth timer is extended by a predetermined number of transmission periods, wherein the transmission period is a transmission period of the designated uplink transmission, and the predetermined number is determined according to sending moment of the designated uplink transmission that is comprised in the first time.

For example, assuming that the designated uplink transmission is SR, in order to ensure SR processing time of a base station, the first time will be extended by the sr-ProhibitTimer. If the sr-ProhibitTimer overlaps or partially overlaps with the first time during its running time, and there is one or more SR-sending moments in the first time, the running time of the sr-ProhibitTimer will be extended by periods of the one or more SR-sending moments. For example, if the running time of the sr-ProhibitTimer is T, the first time comprises M SR-sending moments, and the period of SR-sending moment is N, then the extended running time of the sr-ProhibitTimer will be T+M*N.

Alternatively, if the sr-ProhibitTimer overlaps or partially overlaps with the first time during running time, and there is one or more SR-sending moments in the first time, then the running time of the sr-ProhibitTimer will be extended by the duration of the first time. For example, if the running time of the sr-ProhibitTimer is T, the duration of the first time is N, then the extended evaluation period will be T+N.

(57) Convert or switch to a default bandwidth part (BWP) at beginning moment of the first time. In other words, when the terminal is in an activated BWP, the terminal can switch to the default BWP and stop bwp-InactivityTimer at beginning moment of the first time.

(58) When transmission time of uplink transmission overlaps (or partially overlaps) with the first time, the uplink transmission is retransmitted or is determined as failure.

For example, if a terminal sends an uplink signal (i.e., uplink transmission) such as PUSCH at a time which overlaps with the first time, the sending will be determined as failure and the PUSCH will be retransmitted by the terminal. For example, if the sending moment of the PUSCH overlaps with the first time, the terminal does not send the PUSCH, and determines that the sending of PUSCH fails and performs retransmission.

For another example, if a terminal sends an uplink signal such as PRACH at a time which overlaps with the first time, the terminal determines that the sending of preamble fails and performs retransmission, or determines that the Random Access Channel (RACH) process fails. For example, if the sending moment of PRACH overlaps with the first time, the terminal does not send the PRACH, determines that the sending of PRACH fails and performs sending of PRACH again, or determines that the PRACH process fails.

For another example, if a terminal sends an uplink signal such as PRACH at a time which overlaps with the first time, the terminal determines that the sending of the uplink signal fails and terminates this process. For example, if the sending moment of PRACH overlaps with the first time, the terminal does not send the PRACH, determines that the PRACH process fails, terminates the PRACH process, and reports it to an upper layer.

Further, when a network device is in a silence or power-saving state, for example, when the network device does not send or receive signals, as for a terminal, selecting a cell to which the network device belongs as a service cell will inevitably affect performance of the terminal. In order to avoid this problem, when a terminal determines that a target cell to which a network device belongs may be in a silence or power-saving state (that is, the target cell meets target conditions) based on the first information sent by the network device, then during cell reselection or cell residence, the terminal will lower the priority of the target cell that meets the target conditions, and/or postpone the service-initiation timing of the target cell or target cell access time.

The target conditions comprise at least one of the following (a)-(c).

• • (a) The network device corresponding to the target cell sends a paging message by a secondary carrier or a secondary cell.
  • (b) The network device corresponding to the target cell stops receiving uplink transmission.
  • (c) The network device corresponding to the target cell stops sending downlink transmission.

It should be noted that, as for the terminal lowers the priority of the target cell that meets the aforementioned target conditions during cell reselection as described above, it can be understood as follows: in a cell sorting within a frequency point where cells are located, the terminal will lower the priority of the target cell that meets the above conditions to the minimum; alternatively, in a cell sorting of all frequency points, the terminal will lower the priority of the target cell that meets the above target conditions to the minimum.

Based on this, as a possible implementation, the methods in which a terminal lowers the priority of the target cell that meets the target conditions can include the following manner 1 or manner 2.

Manner 1: lowering the priority of the target cell by calculating a cell-criterion R value. In one implementation, the terminal lowering the priority of a target cell by calculating a cell-criterion R value comprises: subtracting a predetermined offset value from a cell-criterion R value of the target cell so as to obtain a target R value, and the priority of the target cell is determined according to the target R value.

For example, in calculating a cell-criterion R value, for a cell that meets the above conditions, the R value of the cell is reduced by subtracting a positive offset value or added by a negative offset value. In calculating a cell-criterion R value, if a target cell meets the above target conditions, the cell-criterion R value can be subtracted by an offset value Qoffset_NES (positive value). For example, if a target cell (service cell) meets the above target conditions, Rs=Qmeas,s+Qhyst−Qoffsettemp−Qoffset_NES; if a target cell (neighboring cell) meets the above target conditions, Rn=Qmeas,n−Qoffset−Qoffsettemp−Qoffset_NES. It is to be understood that, the aforementioned Rs and Rn both represent a target R value, Qmeas,s and Qmeas,n both represent a reference signal received power (RSRP) value measured by a terminal when reselecting the target cell, Qoffset represents an offset value for adjusting the priority of a cell/frequency point, Qoffsettemp represents an offset value temporarily used to adjust the priority of a cell, and Qhyst represents the hysteresis value for cell reselection. Manner 2: lowering the priority of a target cell that meets the target conditions within the second time, wherein the second time is determined according to the time information of the network device stopping receiving uplink transmission and/or the time information of the network device stopping sending downlink transmission.

It is to be understood that, lowering the priority of a target cell that meets the target conditions within the second time can comprise: starting a fifth timer at beginning moment of the second time; lowering the priority of the target cell that meets the target conditions during running time of the fifth timer; and restoring the priority of the target cell when the fifth timer times out.

For example, the terminal can start a fifth timer at beginning moment of the first time, and a time duration of the fifth timer is the duration; during running time of the fifth timer, the priority of the target cell that meets the target conditions can be lowered in accordance with, but not limited to the manner of calculating a cell-criterion R value; and when the fifth timer times out, the priority of the target cell that meets the target conditions will be restored.

For the terminal receiving first information as mentioned above, in this embodiment, the terminal can receive the first information by an access stratum (AS), and notify a non-access stratum (NAS) of the first information by the access stratum, so that the terminal is aware of the silence or energy-saving state of the network device.

Further, if the terminal resides in a secondary carrier or a secondary cell, then the terminal considers the secondary carrier or the secondary cell as a service cell and needs to measure a reference signal of a primary carrier or a primary cell. Based on this, in this embodiment, in order to achieve the purpose of the terminal measuring a reference signal of a primary carrier or a primary cell on a secondary carrier or a secondary cell, the network device can send measurement configuration information by the secondary carrier or the secondary cell, and the measurement configuration information is used by the terminal to measure a reference signal sent by the primary carrier or the primary cell. Accordingly, after receiving the measurement configuration information on the secondary carrier or the secondary cell, the terminal can measure the reference signal sent by the primary carrier or the primary cell.

In one implementation, the measurement configuration information comprises at least one of the following (a)-(d).

• • (a) Frequency point information of a reference signal of a primary carrier or a primary cell.
  • (b) Time-domain configuration information of a reference signal of a primary carrier or a primary cell.
  • (c) Association of a primary carrier or a primary cell with a reference signal.
  • (d) An indication that a primary carrier or a primary cell has a same QCL relationship as a secondary carrier or a secondary cell.

It should be noted that, where the secondary cell or the secondary carrier has no reference signals, the sending-priority of the reference signal of the primary carrier or the primary cell is higher than the sending-priority of the paging message of the secondary carrier or the secondary cell and the priority of system information of the service cell. In other words, if the secondary carrier or the secondary cell has no reference signals, the terminal considers that the service cell will not send a paging message at a moment when a reference signal of a primary carrier or a primary cell is sent.

As shown in FIG. 4, which is a flow chart of a communication method 400 provided in an exemplary embodiment of the present application, the method 400 can, but is not limited to, be executed by a network device, and specifically can be executed by hardware and/or software installed in the network device.

Wherein the first information is used to instruct or configure at least one of the following:

For example, in this embodiment, the network device can send fourth information before or after sending the first information, so as to instruct or configure a secondary carrier or a secondary cell. For example, the fourth information can be used to instruct or configure at least one of the following (61)-(64).

(61) Configuration information of the secondary carrier or the secondary cell.

(62) Configuration update information of the secondary carrier or the secondary cell.

It is to be understood that, in the case where the fourth information is used to instruct or configure the configuration update information of the secondary carrier or the secondary cell, the fourth information can be relevant information in a system-information-update process, such as paging message, paging-downlink paging instruction information (paging DCI), short message, etc. The instruction or configuration of the configuration update information of the secondary carrier or the secondary cell is illustrated below in combination with Manner 1 and Manner 2.

Manner 1: Instruct the configuration update information of the secondary cell or the secondary carrier by a system-information-update process corresponding to the secondary carrier or the secondary cell.

In the case where the configuration update information of the secondary cell or the secondary carrier is instructed by a system-information-update process corresponding to the secondary carrier or the secondary cell, the terminal resides in the secondary carrier or the secondary cell and considers the secondary carrier or the secondary cell as a service cell. Based on this, the configuration update information of the secondary carrier or the secondary cell is carried by at least one of a paging message, paging-downlink paging instruction information, and a short message in the system-information-update process.

In one implementation, the paging message or short message further carries at least one of the following (a)-(e).

Wherein the primary carrier or the primary cell broadcasting or configuring the system information instruction is the system information of a service cell being broadcast or configured in the primary carrier or the primary cell.
  • (c) A frequency point of a primary carrier or a primary cell. It is to be understood that a frequency point of a primary carrier or a primary cell is the frequency point of the primary carrier or the primary cell that broadcasts or configures the system information.
  • (d) A time-domain resource of a primary carrier or a primary cell for sending the configuration of a secondary carrier or a secondary cell. Wherein the time-domain resource can comprise sending the system information (SI) scheduling window or beginning time, period, and duration, etc., of the PDCCH that is configured by the secondary carrier or the secondary cell on the primary carrier or the primary cell.
  • (e) A frequency-domain resource of a primary carrier or a primary cell for sending the configuration of a secondary carrier or a secondary cell. Wherein the frequency-domain resource can comprise sending beginning position and bandwidth of the PDCCH that is configured by the secondary carrier or the secondary cell on the primary carrier or the primary cell.

Manner 2: Instruct the configuration update information of a secondary cell or a secondary carrier by a system-information-update process corresponding to a primary carrier or a primary cell. In the case where the configuration update information of a secondary cell or a secondary carrier is instructed by a system-information-update process corresponding to a primary carrier or a primary cell, the configuration update information of the secondary carrier or the secondary cell is carried by at least one of paging message, paging-downlink paging instruction information, and short message in the system-information-update process.

In one implementation, at least one of the paging message, the paging-downlink paging instruction information, and the short message further carries the configuration information of physical downlink control channel (PDCCH), such as the beginning moment, period, duration, etc., of PDCCH.

In addition, the paging message or the short message further carries at least one of the following (a)-(c).

  • (b) Time-domain resource for sending the configuration of a secondary carrier or a secondary cell.
  • (c) Frequency-domain resource for sending the configuration of a secondary carrier or a secondary cell.

(63) Enable or disable the secondary carrier or the secondary cell.

For example, the fourth information is an enable-or-disable instruction of a secondary carrier or a secondary cell that is broadcast or configured via a primary carrier or a primary cell by a network device, which is used to instruct whether the state of the secondary carrier or the secondary cell is enabled or disabled, or to instruct an enable-or-disable instruction of a reference signal on the secondary carrier or the secondary cell, or to instruct an enable-or-disable instruction of system information on the secondary carrier or the secondary cell, or to instruct an enable-or-disable instruction of a paging message on the secondary carrier or the secondary cell. In other words, in this embodiment, enabling or disabling a secondary carrier or a secondary cell can comprise at least one of: enabling or disabling the secondary carrier or the secondary cell, enabling or disabling a reference signal of the secondary carrier or secondary cell, enabling or disabling the system information of the secondary carrier or secondary cell, and enabling or disabling a paging message of the secondary carrier or the secondary cell.

(64) Time information when the secondary carrier or the secondary cell is enabled or disabled. Wherein the time information can be the beginning time, duration, ending time, etc., of enabling or disabling the secondary carrier or the secondary cell.

As for the aforementioned sending the fourth information, a network-side device can broadcast or configure a secondary carrier or a secondary cell as a neighboring cell by a primary carrier or a primary cell, and instruct that the neighboring cell is a secondary carrier or a secondary cell; or it can broadcast or configure a secondary carrier or a secondary cell as a secondary carrier or a secondary cell by a primary carrier or a primary cell.

For example, a secondary carrier or a secondary cell is broadcast or configured as a neighboring cell by a primary carrier or a primary cell, and the neighboring cell is instructed as a secondary carrier or a secondary cell. For example, a primary carrier or a primary cell broadcasts or configures the configuration of a neighboring cell in the system information, for example, SIB3, SIB4, SIB5 or a newly introduced SIB (System Information Block), the configuration of a neighboring cell comprises the configuration of a secondary carrier or a secondary cell, and the configuration of a secondary carrier or a secondary cell comprises a frequency point of the secondary carrier or the secondary cell, an instruction of the secondary carrier or the secondary cell, the configuration of the secondary carrier or the secondary cell, whether to send or not to send SSB, whether to send or not to send a paging message, whether to send or not to send the system information, etc. In addition, the aforementioned configuration can further comprise access configuration, wireless resource configuration, cell reselection information, etc.

For another example, a primary carrier or a primary cell broadcasts or configures a secondary carrier or a secondary cell as a secondary carrier or a secondary cell. For example, a primary carrier or a primary cell broadcasts or configures the configuration of a secondary carrier or a secondary cell in the system information, and the configuration of the secondary carrier or the secondary cell comprises a frequency point of the secondary carrier or the secondary cell, an instruction of the secondary carrier or the secondary cell, the configuration of the secondary carrier or the secondary cell, whether to send or not to send SSB, whether to send or not to send a paging message, whether to send the system information, etc. Wherein the secondary carrier or the secondary cell is independent system information that can also be independently mapped to an SI, which is not limited here.

Correspondingly, after receiving the fourth information, the terminal side can perform at least one of the following (a)-(d) according to its own needs.

• • (a) Associate the primary carrier or the primary cell that is used to send the fourth information with the secondary carrier or the secondary cell.
  • (b) Read the configuration information of the secondary carrier or the secondary cell.
  • (c) Save the configuration information of the secondary carrier or the secondary cell.
  • (d) Update the saved configuration information of the secondary carrier or the secondary cell.

Further, when in an idle or inactive state, the terminal receives configuration of the secondary carrier on the primary carrier or the primary cell, and when certain conditions are met (such as the terminal needs to send data on the secondary carrier, or the terminal needs to send a large amount of data, etc.), the terminal can send a Wake up signal (WUS) on the secondary carrier or the secondary cell, so as to request the secondary carrier or the secondary cell to send an SSB or a paging message. After receiving the WUS, the network device sends an SSB and/or a paging message. To achieve this purpose, as a possible implementation, the network device can send third information, and the third information is used to instruct or configure the terminal to send a WUS on the secondary carrier or the secondary cell. Correspondingly, after receiving the third information, the terminal can send a WUS to the network device on the secondary carrier or the secondary cell, and after receiving the WUS, the network device sends a synchronization signal SSB or a paging message on the secondary carrier or the secondary cell.

In one implementation, the third information comprises at least one of the following (71)-(73).

(71) Sending moment of the WUS. For example, the sending moment of the WUS can comprise beginning moment, period, etc. It should be noted that, the sending moment of the WUS takes time of a primary carrier or a primary cell as a reference time. For example, a system frame number (SFN), a subframe, and a time slot of a primary carrier or a primary cell are consistent with those of a secondary carrier or a secondary cell. Then, if a terminal obtains time synchronization of a primary carrier or a primary cell, it can also be considered as obtaining synchronization of a secondary carrier or a secondary cell, and the sending moment of the WUS is calculated according to the delay configuration of the WUS. (72) Offset value of the WUS.

In combination with the aforementioned sending moment of the WUS, in this embodiment, it can be considered that the sending moment of the WUS can be determined according to the offset value of the time when a primary carrier or a primary cell sends a reference signal. For example, the sending moment of a reference signal of a primary carrier or a primary cell is N, the offset value of the WUS is M, then the sending moment of the WUS is N+W.

(73) The sending time window of the WUS. Wherein the sending time window of the WUS can comprise a plurality of sending moments, each sending moment has a QCL relationship with a reference signal of a primary carrier or a primary cell, or has a binding relationship with a beam sent by a primary carrier or a primary cell. For example, if there is a n-th beam of a primary carrier or a primary cell, then within the sending time window of the WUS, the sending moment of the WUS corresponding to the beam is a n-th sending moment.

It should be noted that, the terminal, when sending the WUS, meets the condition that the secondary carrier or a secondary cell is in a disabled state.

As shown in FIG. 5, which is a flow chart of a communication method 500 provided in an exemplary embodiment of the present application, the method 500 can, but is not limited to, be executed by a terminal, and specifically can be executed by hardware and/or software installed in the terminal.
