[0003] In a related scenario, it is necessary to monitor a primary carrier and a secondary carrier, but for the secondary carrier, the amount of data to be transmitted is relatively smaller or the transmission speed is faster, so the primary carrier and the secondary carrier have different monitoring needs.

[0044] In order to facilitate understanding by those skilled in the art, the embodiments of the present disclosure provide a number of embodiments to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the embodiments provided in the embodiments of the present disclosure can be implemented alone, can be implemented together after being combined with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies alone or after being combined, and the embodiments of the present disclosure are not limited thereto.

[0045] In order to better understand the technical solution described in any one of the embodiments of the present disclosure, an application scenario in the related technology will be described first.

[0046] When considering the power saving problem of the terminal, a physical downlink control channel skipping (PDCCH skipping) mechanism can be introduced. The basic operation principle of this mechanism is to send indication information to the terminal to inform the terminal that it can stop monitoring the PDCCH for a certain time, and the indication information may be downlink control information (DCI) indication information.

[0047] Here, the time length range for entering the hibernation state can be notified to the terminal in advance by radio resource control (RRC) based on the network.

[0048] In one embodiment, the DCI indicates a predefined time for skipping monitoring of the PDCCH.

[0049] In one embodiment, M=1, where M is the number of skip intervals set by higher layers, and the scheduling DCI has a 1-bit information field to indicate PDCCH monitoring self-adaptive behavior, the meaning of which is shown in Table 1 below.

[0050] [Table 1]

[0051] If M=2 or M=3, the scheduling DCI has 2-bit information to indicate the PDCCH monitoring self-adaptive behavior, the meaning of which is shown in Table 2 below.

[0052] [Table 2]

[0053] Among them, the basic unit of skip, x, is a slot.

[0054] For the X value in Beh 1A, the candidate skip value is may support time lengths up to 100 ms, X is set and specified in units of slots, The selectable parameters of the candidate X value behavior may be as follows: {1,2,3,…,20,30,40,50,60,80,100}for 15 kHz SCS, {1,2,3,…,40,60,80,100,120,160,200}for 30 kHz SCS, {1,2,3,…,80,120,160,200,240,320,400}for 60kHz SCS, {1,2,3,…,160,240,320,400,480,640,800}for 120kHz SCS, is greater than or equal to the minimum applicable scheduling offset, Additional symbol level or PDCCH monitor period level monitor duration.

[0055] In one embodiment, in a carrier aggregation scenario, whether it is discontinuous reception (DRX) or a wake-up signal, it is common to the PCell and Scell ​​of the carrier aggregation, that is, the primary carrier and the secondary carrier are both monitored at the same time. However, the amount of data for the secondary carrier is always small, or the secondary carrier has a larger bandwidth and faster data transmission in the scenario of using FR2, so the required monitoring time is less than that of the primary carrier. Therefore, a PDCCH skip mechanism can be used.

[0056] As shown in FIG. 2, this embodiment provides a monitor skip method, which is executed by a base station, and includes the following step 21:

[0057] In step 21, physical downlink control channel (PDCCH) monitor skip information is sent to the terminal, where the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on a specified carrier, and the specified carrier includes at least one of a primary carrier and a secondary carrier.

[0058] Here, the terminal according to the present disclosure may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a road side unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device.

[0059] The base station according to the present disclosure may be an access device through which a terminal accesses a network, where the base station may be any type of base station, such as a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

[0060] In one embodiment, the base station sends physical downlink control channel (PDCCH) monitor skip information to the terminal, where the PDCCH monitor skip information instructs the terminal to skip monitoring the PDCCH on a predetermined carrier, and the predetermined carrier includes at least one of a primary carrier and a secondary carrier. After receiving the PDCCH monitor skip information sent from the base station, the terminal determines to monitor the PDCCH on the primary carrier and / or the secondary carrier based on the PDCCH monitor skip information, or determines to skip monitoring the PDCCH on the primary carrier and / or the secondary carrier based on the PDCCH monitor skip information.

[0061] In one embodiment, the base station sends a DCI including PDCCH monitoring skip information to the terminal. After receiving the DCI sent from the base station, the terminal determines to monitor the PDCCH on the primary carrier and / or the secondary carrier according to the PDCCH monitoring skip information included in the DCI, or determines to skip monitoring the PDCCH on the primary carrier and / or the secondary carrier according to the PDCCH monitoring skip information included in the DCI.

[0062] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal on a primary carrier, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on a certain carrier, where the primary carrier may be a Pcell or a Pscell.

[0063] Alternatively, the base station may transmit DCI including PDCCH continuous monitoring information to the terminal, where the PDCCH continuous monitoring information instructs the terminal to continuously monitor the PDCCH on a predetermined carrier.

[0064] In one embodiment, the given carrier may be specified by a protocol or announced by the network.

[0065] In one embodiment, the predetermined carriers specified by the protocol may be all available secondary carriers.

[0066] In one embodiment, the predetermined carrier specified by the protocol may be determined based on a DRX packet, for example, the predetermined carrier is a primary carrier or a secondary carrier in a DRX packet.

[0067] In one embodiment, if a given carrier defined by a protocol is a primary carrier, then all available secondary carriers are also given as the given carrier.

[0068] In one embodiment, the base station may explicitly indicate whether a particular carrier is a primary carrier or a secondary carrier, e.g., by indicating an identifier with one flag and distinguishing the primary carrier from the secondary carrier with different values.

[0069] In one embodiment, the base station may explicitly indicate the range of a given carrier.

[0070] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier. After receiving the PDCCH monitoring skip information, the terminal skips monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information.

[0071] In one embodiment, the time length for skipping the monitoring of the PDCCH on the secondary carrier can be determined according to the power saving requirement parameter. Exemplarily, when the power saving requirement parameter is greater than a parameter threshold, the time length for skipping the monitoring of the PDCCH on the secondary carrier is determined to be less than the time length threshold, or when the power saving requirement parameter is less than the parameter threshold, the time length for skipping the monitoring of the PDCCH on the secondary carrier is determined to be greater than the time length threshold. In this way, the time length for monitoring the PDCCH on the secondary carrier can be adapted to the power saving requirement parameter.

[0072] In one embodiment, the time length for skipping monitoring of the PDCCH on a carrier can be determined based on several time units. For example, the time unit can be ms or a slot. Skipping X time units results in stopping X ms or X slots, where the slot can be determined based on a subcarrier spacing.

[0073] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring PDCCHs on multiple secondary carriers. After receiving the PDCCH monitoring skip information, the terminal skips monitoring PDCCHs on the multiple secondary carriers according to the PDCCH monitoring skip information, where the multiple secondary carriers may be some or all of the secondary carriers supported by the terminal.

[0074] In one embodiment, the base station sends PDCCH monitor skip information to the terminal, where the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier in the secondary carrier group. After receiving the PDCCH monitor skip information, the terminal skips monitoring the PDCCH on the secondary carrier in the secondary carrier group based on the PDCCH monitor skip information. Here, there may be multiple secondary carrier groups, and the multiple secondary carrier groups may be part or all of the secondary carrier groups supported by the terminal. The secondary carrier group may include multiple secondary carriers.

[0075] In one embodiment, in a dual DRX scene, the secondary carrier of FR1 and the secondary carrier of FR2 cannot be set to the same secondary carrier group.

[0076] In one embodiment, in a dual DRX scenario, the secondary carrier of FR1 and the secondary carrier of FR2 cannot be set in the same DRX packet. In one embodiment, the base station sends PDCCH monitor skip information to the terminal, where the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier. In this case, a timer for stopping monitoring on the secondary carrier can be started, and the time length of the timer for stopping monitoring is the time length for skipping monitoring. In one embodiment, the base station sends PDCCH monitor skip information to the terminal, where the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier. After receiving the PDCCH monitor skip information, the terminal does not prematurely terminate the process of skipping monitoring the PDCCH on the secondary carrier, because the terminal needs to subsequently start a random access process on the secondary carrier and needs to monitor a random access response (RAR) on the primary carrier. That is, the skip process is terminated early and the active state is not entered, that is, the timer for stopping the monitoring is not stopped or restarted, because at this time, the terminal does not skip monitoring the PDCCH on the primary carrier, that is, the monitoring on the primary carrier is not affected.

[0077] In one embodiment, if the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier in the secondary carrier group, the effective time length of the PDCCH monitor skip information can be determined based on the minimum subcarrier interval in the BWP set in the enabled secondary carrier group. In one embodiment, if the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier in the secondary carrier group, the effective time length of the PDCCH monitor skip information can be determined based on the subcarrier interval in the currently operating BWP. Note that within the effective time length, the PDCCH monitor skip information is effective, and outside the effective time length, the PDCCH monitor skip information is invalid. If the PDCCH monitor skip information is invalid, the terminal ignores the PDCCH monitor skip information. Or, if the PDCCH monitor skip information is valid, the terminal skips monitoring the PDCCH on a specific carrier based on the PDCCH monitor skip information. In one embodiment, the effective time length may start from the time when the terminal receives the PDCCH monitor skip information.

[0078] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier. After receiving the PDCCH monitoring skip information, the terminal skips monitoring the PDCCH on the primary carrier according to the PDCCH monitoring skip information. However, the terminal does not skip monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information, i.e., does not affect monitoring on the secondary carrier.

[0079] In one embodiment, if the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier and it is determined that the terminal does not skip monitoring the PDCCH on the secondary carrier, the effective time length of the PDCCH monitor skip information can be determined based on the minimum subcarrier spacing in all BWPs set on the primary carrier. In one embodiment, if the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier and it is determined that the terminal does not skip monitoring the PDCCH on the secondary carrier, the effective time length of the PDCCH monitor skip information can be determined based on the subcarrier spacing in the BWP currently activated on the primary carrier. Note that within the effective time length, the PDCCH monitor skip information is effective, and outside the effective time length, the PDCCH monitor skip information is invalid. If the PDCCH monitor skip information is invalid, the terminal ignores the PDCCH monitor skip information. Or, if the PDCCH monitor skip information is valid, the terminal skips monitoring the PDCCH on a predetermined carrier based on the PDCCH monitor skip information. In one embodiment, the effective time length may start from the time when the terminal receives the PDCCH monitor skip information.

[0080] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier. After receiving the PDCCH monitoring skip information, the terminal skips monitoring the PDCCH on the primary carrier according to the PDCCH monitoring skip information. Note that the terminal further skips monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information, i.e., affects monitoring on the secondary carrier.

[0081] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier, and starts a timer to stop monitoring on the primary carrier at this time; and the terminal further skips monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information, i.e. starts a timer to stop monitoring on the secondary carrier when it affects monitoring on the secondary carrier; That is, stopping or continuing monitoring on the primary carrier is effective for the entire terminal, and the terminal can be understood to stop or continue monitoring on all carriers. This behavior may be regulated by a protocol.

[0082] At this time, the terminal processes the timer on the secondary carrier as follows:

[0083] If a timer that would normally stop monitoring is started on the secondary carrier, the timer can be restarted, and the length of time is determined according to the length of time that monitoring is stopped on the primary carrier. For example, if monitoring is first stopped on the secondary carrier for 3 s and then operated for 1 s, and the length of time that monitoring is stopped on the primary carrier is 4 s, the primary carrier operates for 4 s to stop monitoring. Similarly, the timer on the secondary carrier may also be affected by the PDCCH monitoring continuation information on the primary carrier. For example, if monitoring is first stopped on the secondary carrier for 3 s and then operated for 1 s, when a command is received on the primary carrier, monitoring is continued on the specified carrier, the operating timer is stopped, and monitoring is resumed.

[0084] Furthermore, the terminal further skips monitoring of the PDCCH on the secondary carrier based on the PDCCH monitor skip information, i.e., when the monitoring on the secondary carrier is affected, starts a timer to stop monitoring on the secondary carrier as well, and the timer operates according to the monitoring stop time length on the primary carrier and then continues to operate. For example, if monitoring is first stopped for 3 s on the secondary carrier and then operates for 1 s, and the monitoring stop time length on the primary carrier is 4 s, the timer first operates for 4 s according to the primary carrier and then continues to operate for the remaining 2 s.

Note that within the effective time length, the PDCCH monitor skip information is effective, and outside the effective time length, the PDCCH monitor skip information is invalid. If the PDCCH monitor skip information is invalid, the terminal ignores the PDCCH monitor skip information. Or, if the PDCCH monitor skip information is valid, the terminal skips monitoring the PDCCH on a predetermined carrier based on the PDCCH monitor skip information. In one embodiment, the starting point of the effective time length may be the time when the terminal receives the PDCCH monitor skip information.

As one embodiment, a timer is started to stop monitoring on the primary carrier.

[0135] As will be understood by those skilled in the art, the methods provided in the embodiments of the present disclosure may be performed alone or together with several methods in the embodiments of the present disclosure or several methods in related technologies.

[0136] As shown in FIG. 7, this embodiment provides a monitor skip method, which is executed by a terminal, and includes the following step 71:

[0137] In step 71, receive PDCCH monitor skip information sent from the base station, where the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on a specified carrier, and the specified carrier includes at least one of a primary carrier and a secondary carrier.

[0138] Here, the terminal according to the present disclosure may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a road side unit (RSU), a smart home terminal, an industrial sensing device, and / or a medical device.

[0139] The base station according to the present disclosure may be an access device through which a terminal accesses a network, where the base station may be any type of base station, such as a base station of a third generation mobile communication (3G) network, a base station of a fourth generation mobile communication (4G) network, a base station of a fifth generation mobile communication (5G) network, or other evolved base stations.

[0140] In one embodiment, the base station sends physical downlink control channel (PDCCH) monitor skip information to the terminal, where the PDCCH monitor skip information instructs the terminal to skip monitoring the PDCCH on a predetermined carrier, and the predetermined carrier includes at least one of a primary carrier and a secondary carrier. After receiving the PDCCH monitor skip information sent from the base station, the terminal determines to monitor the PDCCH on the primary carrier and / or the secondary carrier based on the PDCCH monitor skip information, or determines to skip monitoring the PDCCH on the primary carrier and / or the secondary carrier based on the PDCCH monitor skip information.

[0141] In one embodiment, the base station sends a DCI including PDCCH monitoring skip information to the terminal. After receiving the DCI sent from the base station, the terminal determines to monitor the PDCCH on the primary carrier and / or the secondary carrier according to the PDCCH monitoring skip information included in the DCI, or determines to skip monitoring the PDCCH on the primary carrier and / or the secondary carrier according to the PDCCH monitoring skip information included in the DCI.

[0142] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal on a primary carrier, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on a certain carrier, where the primary carrier may be a Pcell or a Pscell.

[0143] Alternatively, the base station may transmit DCI including PDCCH continuous monitoring information to the terminal, where the PDCCH continuous monitoring information instructs the terminal to continuously monitor the PDCCH on a predetermined carrier.

[0144] In one embodiment, the given carrier may be specified by a protocol or announced by the network.

[0145] In one embodiment, the predetermined carriers specified by the protocol may be all available secondary carriers.

[0146] In one embodiment, the predetermined carrier specified by the protocol may be determined based on a DRX packet, for example, the predetermined carrier is a primary carrier or a secondary carrier in a DRX packet.

[0147] In one embodiment, if a given carrier defined by a protocol is a primary carrier, then all available secondary carriers are also given as the given carrier.

[0148] In one embodiment, the base station may explicitly indicate whether a particular carrier is a primary carrier or a secondary carrier, e.g., by indicating an identifier with one flag and distinguishing the primary carrier from the secondary carrier with different values.

[0149] In one embodiment, the base station may explicitly indicate the range of a given carrier.

[0150] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier. After receiving the PDCCH monitoring skip information, the terminal skips monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information.

[0151] In one embodiment, the time length for skipping the monitoring of the PDCCH on the secondary carrier can be determined according to the power saving requirement parameter. Exemplarily, when the power saving requirement parameter is greater than a parameter threshold, the time length for skipping the monitoring of the PDCCH on the secondary carrier is determined to be less than the time length threshold, or when the power saving requirement parameter is less than the parameter threshold, the time length for skipping the monitoring of the PDCCH on the secondary carrier is determined to be greater than the time length threshold. In this way, the time length for monitoring the PDCCH on the secondary carrier can be adapted to the power saving requirement parameter.

[0152] In one embodiment, the time length for skipping monitoring of the PDCCH on a carrier can be determined based on several time units. For example, the time unit can be ms or a slot. Skipping X time units results in stopping X ms or X slots, where the slot can be determined based on a subcarrier spacing.

[0153] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring PDCCHs on multiple secondary carriers. After receiving the PDCCH monitoring skip information, the terminal skips monitoring PDCCHs on the multiple secondary carriers according to the PDCCH monitoring skip information, where the multiple secondary carriers may be some or all of the secondary carriers supported by the terminal.

[0154] In one embodiment, the base station sends PDCCH monitor skip information to the terminal, where the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier in the secondary carrier group. After receiving the PDCCH monitor skip information, the terminal skips monitoring the PDCCH on the secondary carrier in the secondary carrier group based on the PDCCH monitor skip information. Here, there may be multiple secondary carrier groups, and the multiple secondary carrier groups may be part or all of the secondary carrier groups supported by the terminal. The secondary carrier group may include multiple secondary carriers.

[0155] In one embodiment, in a dual DRX scene, the secondary carrier of FR1 and the secondary carrier of FR2 cannot be set to the same secondary carrier group.

[0156] In one embodiment, in a dual DRX scenario, the secondary carrier of FR1 and the secondary carrier of FR2 cannot be configured in the same DRX packet.

[0157] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier, in this case, a timer for stopping monitoring can be started on the secondary carrier, and the time length of the timer for stopping monitoring is the monitor skip time length.

[0158] In one embodiment, the base station transmits PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the secondary carrier. After receiving the PDCCH monitoring skip information, the terminal needs to subsequently start a random access process on the secondary carrier and monitor a random access response (RAR) on the primary carrier, so the terminal does not prematurely terminate the process of skipping monitoring the PDCCH on the secondary carrier. That is, the terminal does not prematurely terminate the skip process and enter an active state. That is, the timer for stopping monitoring is not stopped or restarted. At this time, the terminal does not skip monitoring the PDCCH on the primary carrier, that is, it does not affect monitoring on the primary carrier.

[0159] In one embodiment, if the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on a secondary carrier in a secondary carrier group, the valid time length of the PDCCH monitor skip information can be determined based on the minimum subcarrier spacing in the BWP set in the valid secondary carrier group.

[0160] In one embodiment, if the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on a secondary carrier in a secondary carrier group, the effective time length of the PDCCH monitoring skip information can be determined based on the subcarrier spacing in the currently operating BWP.

[0161] In addition, within the valid time length, the PDCCH monitor skip information is valid, and outside the valid time length, the PDCCH monitor skip information is invalid. If the PDCCH monitor skip information is invalid, the terminal ignores the PDCCH monitor skip information. Or, if the PDCCH monitor skip information is valid, the terminal skips monitoring the PDCCH on a predetermined carrier based on the PDCCH monitor skip information. In one embodiment, the starting point of the valid time length may be the time when the terminal receives the PDCCH monitor skip information.

[0162] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier. After receiving the PDCCH monitoring skip information, the terminal skips monitoring the PDCCH on the primary carrier according to the PDCCH monitoring skip information. However, the terminal does not skip monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information, i.e., does not affect monitoring on the secondary carrier.

[0163] In one embodiment, if the PDCCH monitor skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier and it is determined that the terminal does not skip monitoring the PDCCH on the secondary carrier, the effective time length of the PDCCH monitor skip information can be determined based on the minimum subcarrier spacing in all BWPs configured on the primary carrier.

[0164] In one embodiment, if the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier and it is determined that the terminal does not skip monitoring the PDCCH on the secondary carrier, the effective time length of the PDCCH monitoring skip information can be determined based on a subcarrier spacing in the BWP currently activated on the primary carrier.

[0165] In addition, within the valid time length, the PDCCH monitor skip information is valid, and outside the valid time length, the PDCCH monitor skip information is invalid. If the PDCCH monitor skip information is invalid, the terminal ignores the PDCCH monitor skip information. Or, if the PDCCH monitor skip information is valid, the terminal skips monitoring the PDCCH on a predetermined carrier based on the PDCCH monitor skip information. In one embodiment, the starting point of the valid time length may be the time when the terminal receives the PDCCH monitor skip information.

[0166] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier. After receiving the PDCCH monitoring skip information, the terminal skips monitoring the PDCCH on the primary carrier according to the PDCCH monitoring skip information. Note that the terminal further skips monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information, i.e., affects monitoring on the secondary carrier.

[0167] In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, where the PDCCH monitoring skip information indicates that the terminal skips monitoring the PDCCH on the primary carrier, and starts a timer to stop monitoring on the primary carrier at this time; and the terminal further skips monitoring the PDCCH on the secondary carrier according to the PDCCH monitoring skip information, i.e. starts a timer to stop monitoring on the secondary carrier when it affects monitoring on the secondary carrier; That is, stopping or continuing monitoring on the primary carrier is effective for the entire terminal, and the terminal can be understood to stop or continue monitoring on all carriers. This behavior may be regulated by a protocol.

[0168] At this time, the terminal processes the timer on the secondary carrier as follows:

[0169] If a timer that would normally stop monitoring is started on the secondary carrier, the timer can be restarted, and the length of time is determined according to the length of time that monitoring is stopped on the primary carrier. For example, if monitoring is first stopped on the secondary carrier for 3 s and then operated for 1 s, and the length of time that monitoring is stopped on the primary carrier is 4 s, the primary carrier operates for 4 s to stop monitoring. Similarly, the timer on the secondary carrier may also be affected by the PDCCH monitoring continuation information on the primary carrier. For example, if monitoring is first stopped on the secondary carrier for 3 s and then operated for 1 s, when a command is received on the primary carrier, monitoring is continued on the specified carrier, the operating timer is stopped, and monitoring is resumed.

[0170] Furthermore, the terminal further skips monitoring of the PDCCH on the secondary carrier based on the PDCCH monitor skip information, i.e., when the monitoring on the secondary carrier is affected, starts a timer to stop monitoring on the secondary carrier as well, and the timer operates according to the monitoring stop time length on the primary carrier and then continues to operate.
