[0108] To facilitate understanding by those skilled in the art, this disclosure provides multiple embodiments to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.
[0109] To better understand the technical solutions described in any embodiment of this disclosure, the application scenarios in the related technologies are first explained:
[0110] When considering terminal power saving, a Physical Downlink Control Channel (PDCCH) skipping mechanism can be introduced. The basic working principle of this mechanism is to send an indication message to the terminal, notifying it that it can stop listening to the PDCCH for a predetermined time. The indication message can be Downlink Control Information (DCI) indication message.
[0111] Here, the duration range for notifying the terminal to enter sleep mode can be determined in advance via Radio Resource Control (RRC) based on the network.
[0112] In one embodiment, the DCI indicates a scheduled time to skip listening to the PDCCH.
[0113] In one embodiment, M=1, where M is the number of skip intervals configured by the higher layer. The scheduling DCI has a 1-bit information field used to indicate the PDCCH listening adaptive behavior, the meaning of which is shown in Table 1 below:
[0114] Table 1:
[0115] Bit indication Terminal behavior 0 Beh1 1 Beh1A
[0116] If M=2 or M=3, the scheduling DCI contains 2 bits of information to indicate the PDCCH listening adaptive behavior, the meaning of which is shown in Table 2 below:
[0117] Table 2:
[0118] Bit indication Terminal behavior 00 Beh1 01 Beh1A 10 Beh1A and application skip time period 2 11 If M=3, Beh1A and the application skips time period 3; if M=2, the information field is retained.
[0119] The basic unit for skipping is x, and its unit is slot.
[0120] For the X value in Beh 1A, the candidate skip values can be:
[0121] It supports a maximum duration of 100ms;
[0122] X is configured and indicated in units of time slots;
[0123] Optional parameters for working with candidate X values:
[0124] {1,2,3,…,20,30, 40, 50, 60, 80, 100} for 15 kHz SCS;
[0125] {1,2,3,…,40, 60, 80, 100, 120,160,200} for 30 kHz SCS;
[0126] {1,2,3,…,80, 120, 160, 200, 240, 320,400} for 60kHz SCS;
[0127] {1,2,3,…,160, 240, 320,400, 480, 640,800} for 120kHz SCS;
[0128] Equal to or longer than the applicable minimum scheduling offset;
[0129] Additional symbol level or PDCCH monitoring cycle level listening duration.
[0130] In one embodiment, in a carrier aggregation scenario, both Discontinuous Reception (DRX) and wake-up signals are common to the PCell and Scell of the carrier aggregation; that is, the primary and secondary carriers are listened to simultaneously. However, the secondary carrier often has a smaller data volume, or in scenarios where the secondary carrier uses FR2, due to its larger bandwidth and faster data transmission, the required listening time is less than that of the primary carrier. Therefore, a PDCCH skipping mechanism can be used.
[0131] like Figure 2 As shown, this embodiment provides a method for bypassing eavesdropping, wherein the method is executed by the base station and includes:
[0132] Step 21: Send Physical Downlink Control Channel (PDCCH) listening skip information to the terminal, wherein the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on a predetermined carrier; the predetermined carrier includes at least one of the primary carrier and the secondary carrier.
[0133] Here, the terminals involved in this disclosure may be, but are not limited to, mobile phones, wearable devices, vehicle terminals, roadside units (RSUs), smart home terminals, industrial sensing devices and / or medical devices, etc.
[0134] The base station involved in this disclosure can be an access device for a terminal to access a network. Here, the base station can be various types of base stations, such as base stations for third-generation mobile communication (3G) networks, base stations for fourth-generation mobile communication (4G) networks, base stations for fifth-generation mobile communication (5G) networks, or other evolved base stations.
[0135] In one embodiment, the base station sends Physical Downlink Control Channel (PDCCH) snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on a predetermined carrier; the predetermined carrier includes at least one of a primary carrier and a secondary carrier. After receiving the PDCCH snooping skip information sent by the base station, the terminal determines, based on the PDCCH snooping skip information, whether to snoop on the primary carrier and / or the secondary carrier; or, based on the PDCCH snooping skip information, determines to skip snooping on the primary carrier and / or the secondary carrier.
[0136] In one embodiment, the base station sends a DCI carrying PDCCH snooping skip information to the terminal. After receiving the DCI sent by the base station, the terminal determines whether to snoop on the primary carrier and / or the secondary carrier based on the PDCCH snooping skip information carried in the DCI; or, based on the PDCCH snooping skip information carried in the DCI, determines whether to skip snooping on the primary carrier and / or the secondary carrier.
[0137] In one embodiment, the base station sends PDCCH snooping skip information to the terminal on the primary carrier. This PDCCH snooping skip information instructs the terminal to skip snooping on the PDCCH on a predetermined carrier. Here, the primary carrier can be a Pcell or a Pscell.
[0138] It should be noted that the base station can also send a DCI (Distributed Control Information) to the terminal carrying PDCCH (Programmable Channel Control) continued listening information. This PDCCH continued listening information instructs the terminal to continue listening to the PDCCH on the predetermined carrier.
[0139] In one embodiment, the predetermined carrier may be agreed upon by a protocol or notified by the network.
[0140] In one embodiment, the predetermined carrier agreed upon in the protocol can be all available secondary carriers.
[0141] In one embodiment, the predetermined carrier agreed upon in the protocol may be determined based on a certain DRX packet. For example, the predetermined carrier may be the primary carrier or the secondary carrier on a certain DRX packet.
[0142] In one embodiment, if the predetermined carrier agreed upon in the protocol is the primary carrier, then all the secondary carriers that can be used are also considered predetermined carriers.
[0143] In one embodiment, the base station explicitly indicates whether the predetermined carrier is a primary carrier or a secondary carrier; for example, a Flag indicator can be used to distinguish between the primary and secondary carriers with different values.
[0144] In one embodiment, the base station may explicitly indicate the range of a predetermined carrier.
[0145] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on the PDCCH on the secondary carrier. After receiving the PDCCH snooping skip information, the terminal will skip snooping on the PDCCH on the secondary carrier according to the PDCCH snooping skip information.
[0146] In one embodiment, the duration for skipping PDCCH listening on the secondary carrier can be determined based on power-saving requirement parameters. For example, if the power-saving requirement parameter is greater than a parameter threshold, the duration for skipping PDCCH listening on the secondary carrier is determined to be less than the duration threshold; or, if the power-saving requirement parameter is less than the parameter threshold, the duration for skipping PDCCH listening on the secondary carrier is determined to be greater than the duration threshold. Thus, the duration for listening to PDCCH on the secondary carrier can be adapted to the power-saving requirement parameters.
[0147] In one embodiment, the duration for which PDCCH listening on the carrier is skipped can be determined based on several time units. For example, the time unit is ms, or a slot. Skipping X time units means stopping for X ms or X slots. The slot can be determined based on the subcarrier interval.
[0148] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on multiple secondary carriers. Upon receiving the PDCCH snooping skip information, the terminal will skip snooping on the multiple secondary carriers according to the information. Here, the multiple secondary carriers may be some or all of the secondary carriers supported by the terminal.
[0149] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on secondary carriers within a secondary carrier group. Upon receiving the PDCCH snooping skip information, the terminal will skip snooping on PDCCH on secondary carriers within that secondary carrier group according to the PDCCH snooping skip information. Here, there can be multiple secondary carrier groups, which may be some or all of the secondary carrier groups supported by the terminal. A secondary carrier group may contain multiple secondary carriers.
[0150] In one embodiment, in a dual DRX scenario, the secondary carriers of FR1 and FR2 cannot be configured in the same secondary carrier group.
[0151] In one embodiment, in a dual DRX scenario, the secondary carriers of FR1 and FR2 cannot be configured in the same DRX packet. In one embodiment, the base station sends PDCCH listening skip information to the terminal, instructing the terminal to skip listening to the PDCCH on the secondary carrier. At this time, a timer to stop listening can be started on the secondary carrier, and the duration of the timer is the duration of the skipped listening. In another embodiment, the base station sends PDCCH listening skip information to the terminal, instructing the terminal to skip listening to the PDCCH on the secondary carrier. After receiving this PDCCH listening skip information, if the terminal subsequently needs to initiate a random access procedure on the secondary carrier, and needs to listen for the Random Access Response (RAR) on the primary carrier, it will not prematurely end the skipped PDCCH listening process on the secondary carrier. That is, it will not prematurely terminate the skipped process and enter an active state. In other words, the timer to stop listening will not stop or restart. Because the terminal will not skip listening to the PDCCH on the primary carrier at this time, it will not affect the listening on the primary carrier.
[0152] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on a secondary carrier within a secondary carrier group, the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier spacing on the BWP configured on the effective secondary carrier group. In another embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on a secondary carrier within a secondary carrier group, the effective duration of the PDCCH listening skip information can be determined based on the subcarrier spacing on the currently active BWP. It should be noted that the PDCCH listening skip information is valid within its effective duration; it is invalid outside of the effective duration. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on a predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.
[0153] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip listening to the PDCCH on the primary carrier. Upon receiving this PDCCH snooping skip information, the terminal will skip listening to the PDCCH on the primary carrier according to the information. It should be noted that the terminal will not skip listening to the PDCCH on the secondary carrier according to the PDCCH snooping skip information; that is, it will not affect listening on the secondary carrier.
[0154] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on the primary carrier and it is determined that the terminal will not skip listening to PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier spacing across all BWPs configured on the primary carrier. In another embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on the primary carrier and it is determined that the terminal will not skip listening to PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the subcarrier spacing across the currently active BWP on the primary carrier. It should be noted that the PDCCH listening skip information is valid within its effective duration; it is invalid outside of its effective duration. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on the predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.
[0155] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, instructing the terminal to skip snooping on the primary carrier. Upon receiving this information, the terminal will skip snooping on the primary carrier. It should be noted that the terminal will also skip snooping on the secondary carrier based on the PDCCH snooping skip information, thus affecting snooping on the secondary carrier.
[0156] In one embodiment, the base station sends PDCCH listening skip information to the terminal. This information instructs the terminal to skip listening to the PDCCH on the primary carrier, at which point a stop-listening timer is started on the primary carrier. Furthermore, based on the PDCCH listening skip information, the terminal may also skip listening to the PDCCH on the secondary carrier, meaning that when listening on the secondary carrier occurs, a stop-listening timer will also be started on the secondary carrier.
[0157] This can be understood as the stopping or continuing of listening on the primary carrier affecting the entire terminal; the terminal will either stop listening or continue listening on all carriers. This behavior can be a protocol convention.
[0158] At this time, the terminal handles the timer on the secondary carrier as follows:
[0159] If a timer for stopping listening was already running on the secondary carrier, this timer can be restarted, with its duration determined by the duration of the stop listening on the primary carrier. For example, if the secondary carrier stops listening for 3 seconds, and after running for 1 second, if the primary carrier's stop listening duration is 4 seconds, then the timer will run for 4 seconds as per the primary carrier's stop listening. Similarly, the timer on the secondary carrier may also be affected by PDCCH listening continuation information on the primary carrier. For instance, if the secondary carrier stops listening for 3 seconds, and after running for 1 second, receives a command from the primary carrier to resume listening, then the running timer will stop and listening will resume.
[0160] Going a step further, the terminal, based on the PDCCH listening skip information, will also skip listening to the PDCCH on the secondary carrier. This means that when listening on the secondary carrier, a timer will also be started on the secondary carrier to stop listening. This timer will run for the duration of the stop listening on the primary carrier, and then continue running. For example, if the secondary carrier stops listening for 3 seconds, and after running for 1 second, if the stop listening duration on the primary carrier is 4 seconds, then it will run for 4 seconds according to the primary carrier, and then continue running for the remaining 2 seconds.
[0161] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on the primary carrier and it is determined that the terminal will skip listening to PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier spacing of all BWPs configured on the primary carrier or the minimum subcarrier spacing of the BWPs activated by the terminal on the primary carrier. It should be noted that the PDCCH listening skip information is valid within its effective duration; outside of its effective duration, the PDCCH listening skip information is invalid. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on the predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.
[0162] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on the primary carrier and determines that the terminal will skip listening to PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier interval of all BWPs configured on the primary and secondary carriers, or the minimum subcarrier interval of the BWP activated by the terminal on the primary carrier. As an example, a timer to stop listening is started on the primary carrier. It should be noted that the PDCCH listening skip information is valid within its effective duration; outside of its effective duration, the PDCCH listening skip information is invalid. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on the predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.
[0163] In one embodiment, if the PDCCH skipping information indicates that the terminal skips PDCCH listening on the primary carrier and initiates a random access procedure on the primary carrier, the terminal will prematurely terminate the skipping of PDCCH listening on the primary carrier. That is, PDCCH skipping will be affected. A timer started on the primary carrier to stop listening will stop, and the primary carrier will enter an active time or active state.
[0164] In one embodiment, if the PDCCH skipping information indicates that the terminal skips listening to the PDCCH on the secondary carrier and initiates a random access procedure on the secondary carrier, the terminal will prematurely terminate skipping the PDCCH listening on the primary carrier. That is, the PDCCH skipping will be affected. Here, prematurely terminating the skipping of PDCCH listening on the primary carrier can be achieved by prematurely terminating a timer set for the primary carrier.
[0165] In one embodiment, if the PDCCH skipping information indicates that the terminal skips listening to the PDCCH on both the primary and secondary carriers and initiates a random access procedure on the secondary carrier, the terminal will prematurely terminate skipping the PDCCH listening on the primary carrier. That is, the PDCCH skipping will be affected. Here, prematurely terminating the skipping of PDCCH listening on the primary carrier can be achieved by prematurely terminating a timer set for the primary carrier.
[0166] In one embodiment, if the PDCCH listening skip information indicates that the terminal skips listening to the PDCCH on the secondary carrier and initiates a random access procedure on the secondary carrier, the terminal will prematurely terminate the skipping of listening to the PDCCH on both the primary and secondary carriers. That is, the PDCCH skipping will be affected. Here, prematurely terminating the skipping of listening to the PDCCH on the primary carrier and / or the secondary carrier can be achieved by prematurely terminating a timer set for the primary and / or secondary carriers.
[0167] In one embodiment, the base station receives auxiliary information sent by the terminal, wherein the auxiliary information is used to assist the base station in sending PDCCH snooping skip information to the terminal.
[0168] In one embodiment, the base station receives auxiliary information reported by the terminal indicating a desire to skip listening. Exemplarily, this auxiliary information indicates the number of secondary carrier groups for which skipping listening is desired. Exemplarily, this auxiliary information indicates that both the primary and secondary carriers are expected to hibernate.
[0169] In one embodiment, the base station receives auxiliary information reported by the terminal indicating the terminal's ability to skip listening. For example, the auxiliary information indicates whether skip listening is supported or not; and / or, the auxiliary information indicates whether skip listening is supported or not for secondary carriers in carrier aggregation; and / or, the auxiliary information indicates whether skip listening is supported or not for both the primary and secondary carriers.
[0170] In this embodiment, a Physical Downlink Control Channel (PDCCH) listening skip information is sent to the terminal. This PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on a predetermined carrier; the predetermined carrier includes at least one of a primary carrier and a secondary carrier. Thus, since the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on the primary carrier and / or the secondary carrier, the terminal can determine whether to listen to the PDCCH on the primary carrier and / or the secondary carrier based on the PDCCH listening skip information. Compared to the method where listening to the PDCCH on the primary carrier and / or the secondary carrier is always required, this saves power and improves the terminal's battery life.
[0171] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0172] like Figure 3 As shown, this embodiment provides a method for bypassing eavesdropping, wherein the method is executed by the base station and includes:
[0173] Step 31: Send PDCCH listen-skip information to the terminal on the main carrier.
[0174] Here, the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on a predetermined carrier; the predetermined carrier includes at least one of the primary carrier and the secondary carrier.
[0175] In one embodiment, the base station sends PDCCH snooping skip information to the terminal on the primary carrier. This information instructs the terminal to skip snooping on the PDCCH on the predetermined carrier. Here, the primary carrier can be a Pcell or a Pscell. Upon receiving the PDCCH snooping skip information, the terminal can skip snooping on the predetermined carrier.
[0176] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0177] In one embodiment, the predetermined carrier is a secondary carrier; PDCCH skip information indication:
[0178] At least one secondary carrier;
[0179] And / or,
[0180] At least one secondary carrier group, wherein the secondary carrier group comprises multiple secondary carriers within the same frequency range FR.
[0181] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on at least one secondary carrier. Upon receiving the PDCCH snooping skip information, the terminal will skip snooping on the at least one secondary carrier according to the PDCCH snooping skip information. Here, the at least one secondary carrier can be some or all of the secondary carriers supported by the terminal.
[0182] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on secondary carriers within at least one secondary carrier group. Upon receiving the PDCCH snooping skip information, the terminal will skip snooping on PDCCH on secondary carriers within the at least one secondary carrier group according to the PDCCH snooping skip information. Here, the at least one secondary carrier group can be some or all of the secondary carrier groups supported by the terminal. A secondary carrier group can contain multiple secondary carriers.
[0183] In one embodiment, the predetermined carrier is a secondary carrier; the PDCCH skipping information instructs the terminal to initiate a random access procedure on the secondary carrier without prematurely terminating PDCCH listening on the secondary carrier.
[0184] In one embodiment, the base station sends a PDCCH snooping skip message to the terminal, wherein the PDCCH snooping skip message instructs the terminal to skip snooping on the PDCCH on the secondary carrier. After receiving the PDCCH snooping skip message, the terminal initiates a random access procedure on the secondary carrier without prematurely terminating the skipping of PDCCH snooping on the secondary carrier.
[0185] In one embodiment, the base station sends a PDCCH snooping skip message to the terminal, wherein the PDCCH snooping skip message instructs the terminal to skip snooping on the PDCCH on the secondary carrier. After receiving the PDCCH snooping skip message, the terminal initiates a random access procedure on the secondary carrier without prematurely terminating the skipping of PDCCH snooping on the secondary carrier. Here, because the terminal is snooping on the RAR on the primary carrier, it will not prematurely terminate the skipping of PDCCH snooping on the secondary carrier.
[0186] like Figure 4 As shown, this embodiment provides a method for bypassing eavesdropping, wherein the method is executed by the base station and includes:
[0187] Step 41: Determine the effective duration of the PDCCH skip information based on the subcarrier spacing of the bandwidth portion BWP configured for the secondary carrier group; or, determine the effective duration of the PDCCH skip information based on the subcarrier spacing of the BWP currently used by the terminal on the secondary carrier.
[0188] In one embodiment, if the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on a secondary carrier within a secondary carrier group, the effective duration of the PDCCH snooping skip information can be determined based on the minimum subcarrier spacing on the BWP configured on the effective secondary carrier group. It should be noted that the PDCCH snooping skip information is valid within its effective duration; it is invalid outside of the effective duration. If the PDCCH snooping skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH snooping skip information is valid, the terminal will skip snooping on the predetermined carrier based on the PDCCH snooping skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH snooping skip information.
[0189] In one embodiment, if the PDCCH snooping skip information instructs the terminal to skip snooping on the PDCCH on a secondary carrier within a secondary carrier group, the effective duration of the PDCCH snooping skip information can be determined based on the subcarrier spacing on the BWP currently used by the terminal on the secondary carrier. It should be noted that the PDCCH snooping skip information is valid within its effective duration; outside of its effective duration, the PDCCH snooping skip information is invalid. If the PDCCH snooping skip information is invalid, the terminal will ignore it.

[0191] In one embodiment, the predetermined carrier is either a primary carrier or a secondary carrier; the PDCCH skip information indication:
[0192] Skip the PDCCH listening on the primary carrier and listen to the PDCCH on the secondary carrier; or skip the PDCCH listening on both the primary and secondary carriers.
[0193] In one embodiment, the base station sends PDCCH listening skip information to the terminal, wherein the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on the primary carrier. Upon receiving this PDCCH listening skip information, the terminal will skip listening to the PDCCH on the primary carrier and continue listening to the PDCCH on the secondary carrier. It should be noted that the terminal will not skip listening to the PDCCH on the secondary carrier based on the PDCCH listening skip information; that is, it will not affect listening on the secondary carrier.
[0194] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, instructing the terminal to skip snooping on the primary carrier. Upon receiving this information, the terminal will skip both PDCCH snooping on the primary carrier and PDCCH snooping on the secondary carrier. It should be noted that the terminal will also skip PDCCH snooping on the secondary carrier based on the PDCCH snooping skip information, thus affecting snooping on the secondary carrier.

[0197] In one embodiment, the base station determines the duration of skipping the PDCCH on the secondary carrier based on the duration of skipping the PDCCH on the primary carrier.
[0198] Here, the duration of skipping the PDCCH on the primary carrier is the same as the duration of skipping the PDCCH on the secondary carrier.
[0199] like Figure 5 As shown, this embodiment provides a method for bypassing eavesdropping, wherein the method is executed by the base station and includes:

[0201] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on the primary carrier and it is determined that the terminal will skip listening to PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier interval across all BWPs configured on the primary carrier. It should be noted that the PDCCH listening skip information is valid within its effective duration; outside of its effective duration, the PDCCH listening skip information is invalid. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on the predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.

It should be noted that the PDCCH listening skip information is valid within its effective duration; outside of its effective duration, the PDCCH listening skip information is invalid. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on the predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.

[0204] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0205] In one embodiment, the PDCCH skips the information indication:
[0206] Determine to initiate a random access procedure on the primary carrier, and terminate early to skip listening to the PDCCH on the primary carrier;
[0207] or,
[0208] Determine to initiate a random access procedure on the secondary carrier, and terminate early to skip listening to the PDCCH on the primary carrier;
[0209] or,
[0210] The random access procedure is initiated on the secondary carrier, and the process is terminated early to skip listening to the PDCCH on both the primary and secondary carriers.

[0214] like Figure 6 As shown, this embodiment provides a method for bypassing eavesdropping, wherein the method is executed by the base station and includes:
[0215] Step 61: Receive auxiliary information sent by the terminal, wherein the auxiliary information includes at least information on the expectation of skipping the PDCCH monitoring.

[0223] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0224] like Figure 7 As shown, this embodiment provides a method for skipping monitoring, wherein the method is executed by the terminal and includes:
[0225] Step 71: Receive PDCCH listening skip information sent by the base station, wherein the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on a predetermined carrier; the predetermined carrier includes at least one of the primary carrier and the secondary carrier.
[0226] Here, the terminals involved in this disclosure may be, but are not limited to, mobile phones, wearable devices, vehicle terminals, roadside units (RSUs), smart home terminals, industrial sensing devices and / or medical devices, etc.
[0227] The base station involved in this disclosure can be an access device for a terminal to access a network. Here, the base station can be various types of base stations, such as base stations for third-generation mobile communication (3G) networks, base stations for fourth-generation mobile communication (4G) networks, base stations for fifth-generation mobile communication (5G) networks, or other evolved base stations.
[0228] In one embodiment, the base station sends Physical Downlink Control Channel (PDCCH) snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on a predetermined carrier; the predetermined carrier includes at least one of a primary carrier and a secondary carrier. After receiving the PDCCH snooping skip information sent by the base station, the terminal determines, based on the PDCCH snooping skip information, whether to snoop on the primary carrier and / or the secondary carrier; or, based on the PDCCH snooping skip information, determines to skip snooping on the primary carrier and / or the secondary carrier.
[0229] In one embodiment, the base station sends a DCI carrying PDCCH snooping skip information to the terminal. After receiving the DCI sent by the base station, the terminal determines whether to snoop on the primary carrier and / or the secondary carrier based on the PDCCH snooping skip information carried in the DCI; or, based on the PDCCH snooping skip information carried in the DCI, determines whether to skip snooping on the primary carrier and / or the secondary carrier.
[0230] In one embodiment, the base station sends PDCCH snooping skip information to the terminal on the primary carrier. This PDCCH snooping skip information instructs the terminal to skip snooping on the PDCCH on a predetermined carrier. Here, the primary carrier can be a Pcell or a Pscell.
[0231] It should be noted that the base station can also send a DCI (Distributed Control Information) to the terminal carrying PDCCH (Programmable Channel Control) continued listening information. This PDCCH continued listening information instructs the terminal to continue listening to the PDCCH on the predetermined carrier.
[0232] In one embodiment, the predetermined carrier may be agreed upon by a protocol or notified by the network.
[0233] In one embodiment, the predetermined carrier agreed upon in the protocol can be all available secondary carriers.
[0234] In one embodiment, the predetermined carrier agreed upon in the protocol may be determined based on a certain DRX packet. For example, the predetermined carrier may be the primary carrier or the secondary carrier on a certain DRX packet.
[0235] In one embodiment, if the predetermined carrier agreed upon in the protocol is the primary carrier, then all the secondary carriers that can be used are also considered predetermined carriers.
[0236] In one embodiment, the base station explicitly indicates whether the predetermined carrier is a primary carrier or a secondary carrier; for example, a Flag indicator can be used to distinguish between the primary and secondary carriers with different values.
[0237] In one embodiment, the base station may explicitly indicate the range of a predetermined carrier.
[0238] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on the PDCCH on the secondary carrier. After receiving the PDCCH snooping skip information, the terminal will skip snooping on the PDCCH on the secondary carrier according to the PDCCH snooping skip information.
[0239] In one embodiment, the duration for skipping PDCCH listening on the secondary carrier can be determined based on power-saving requirement parameters. For example, if the power-saving requirement parameter is greater than a parameter threshold, the duration for skipping PDCCH listening on the secondary carrier is determined to be less than the duration threshold; or, if the power-saving requirement parameter is less than the parameter threshold, the duration for skipping PDCCH listening on the secondary carrier is determined to be greater than the duration threshold. Thus, the duration for listening to PDCCH on the secondary carrier can be adapted to the power-saving requirement parameters.
[0240] In one embodiment, the duration for which PDCCH listening on the carrier is skipped can be determined based on several time units. For example, the time unit is ms, or a slot. Skipping X time units means stopping for X ms or X slots. The slot can be determined based on the subcarrier interval.
[0241] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on multiple secondary carriers. Upon receiving the PDCCH snooping skip information, the terminal will skip snooping on the multiple secondary carriers according to the information. Here, the multiple secondary carriers may be some or all of the secondary carriers supported by the terminal.
[0242] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on secondary carriers within a secondary carrier group. Upon receiving the PDCCH snooping skip information, the terminal will skip snooping on PDCCH on secondary carriers within that secondary carrier group according to the PDCCH snooping skip information. Here, there can be multiple secondary carrier groups, which may be some or all of the secondary carrier groups supported by the terminal. A secondary carrier group may contain multiple secondary carriers.
[0243] In one embodiment, in a dual DRX scenario, the secondary carriers of FR1 and FR2 cannot be configured in the same secondary carrier group.
[0244] In one embodiment, in a dual DRX scenario, the secondary carriers of FR1 and FR2 cannot be configured in the same DRX group.
[0245] In one embodiment, the base station sends a PDCCH listening skip message to the terminal, wherein the PDCCH listening skip message instructs the terminal to skip listening to the PDCCH on the secondary carrier. At this time, a timer to stop listening can be started on the secondary carrier, and the duration of the timer to stop listening is the duration of skipping listening.
[0246] In one embodiment, the base station sends a PDCCH listening skip message to the terminal, instructing the terminal to skip listening to the PDCCH on the secondary carrier. Upon receiving this message, if the terminal subsequently needs to initiate a random access procedure on the secondary carrier and needs to listen for a random access response (RAR) on the primary carrier, it will not prematurely terminate the skipped PDCCH listening process on the secondary carrier. That is, it will not prematurely terminate the skipping process and enter an active state. In other words, the timer for stopping listening will not stop or restart. Because the terminal will not skip listening to the PDCCH on the primary carrier at this time, it will not affect the listening on the primary carrier.
[0247] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on a secondary carrier within a secondary carrier group, the duration of the effective PDCCH listening skip information can be determined based on the minimum subcarrier interval on the BWP configured on the effective secondary carrier group.
[0248] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on a secondary carrier within the secondary carrier group, the duration of the effective PDCCH listening skip information can be determined based on the subcarrier spacing on the currently operating BWP.
[0249] It should be noted that the PDCCH listener skip information is valid within the effective duration; it is invalid outside the effective duration. If the PDCCH listener skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listener skip information is valid, the terminal will skip listening to the PDCCH on the predetermined carrier based on the PDCCH listener skip information. In one embodiment, the starting point of the effective duration can be the time when the terminal receives the PDCCH listener skip information.
[0250] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip listening to the PDCCH on the primary carrier. Upon receiving this PDCCH snooping skip information, the terminal will skip listening to the PDCCH on the primary carrier according to the information. It should be noted that the terminal will not skip listening to the PDCCH on the secondary carrier according to the PDCCH snooping skip information; that is, it will not affect listening on the secondary carrier.
[0251] In one embodiment, if the PDCCH listening skip information indicates that the terminal will skip listening to the PDCCH on the primary carrier and it is determined that the terminal will not skip listening to the PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier interval on all BWPs configured on the primary carrier.
[0252] In one embodiment, if the PDCCH listening skip information indicates that the terminal will skip listening to the PDCCH on the primary carrier and it is determined that the terminal will not skip listening to the PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the subcarrier interval on the currently active BWP on the primary carrier.
[0253] It should be noted that the PDCCH listener skip information is valid within the effective duration; it is invalid outside the effective duration. If the PDCCH listener skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listener skip information is valid, the terminal will skip listening to the PDCCH on the predetermined carrier based on the PDCCH listener skip information. In one embodiment, the starting point of the effective duration can be the time when the terminal receives the PDCCH listener skip information.
[0254] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, instructing the terminal to skip snooping on the primary carrier. Upon receiving this information, the terminal will skip snooping on the primary carrier. It should be noted that the terminal will also skip snooping on the secondary carrier based on the PDCCH snooping skip information, thus affecting snooping on the secondary carrier.
[0255] In one embodiment, the base station sends PDCCH listening skip information to the terminal. This information instructs the terminal to skip listening to the PDCCH on the primary carrier, at which point a stop-listening timer is started on the primary carrier. Furthermore, based on the PDCCH listening skip information, the terminal may also skip listening to the PDCCH on the secondary carrier, meaning that when listening on the secondary carrier occurs, a stop-listening timer will also be started on the secondary carrier.
[0256] This can be understood as the stopping or continuing of listening on the primary carrier affecting the entire terminal; the terminal will either stop listening or continue listening on all carriers. This behavior can be a protocol convention.
[0257] At this time, the terminal handles the timer on the secondary carrier as follows:
[0258] If a timer for stopping listening was already running on the secondary carrier, this timer can be restarted, with its duration determined by the duration of the stop listening on the primary carrier. For example, if the secondary carrier stops listening for 3 seconds, and after running for 1 second, if the primary carrier's stop listening duration is 4 seconds, then the timer will run for 4 seconds as per the primary carrier's stop listening. Similarly, the timer on the secondary carrier may also be affected by PDCCH listening continuation information on the primary carrier. For instance, if the secondary carrier stops listening for 3 seconds, and after running for 1 second, receives a command from the primary carrier to resume listening, then the running timer will stop and listening will resume.
[0259] Going a step further, the terminal, based on the PDCCH listening skip information, will also skip listening to the PDCCH on the secondary carrier. This means that when listening on the secondary carrier, a timer will also be started on the secondary carrier to stop listening. This timer will run for the duration of the stop listening on the primary carrier, and then continue running. For example, if the secondary carrier stops listening for 3 seconds, and after running for 1 second, if the stop listening duration on the primary carrier is 4 seconds, then it will run for 4 seconds according to the primary carrier, and then continue running for the remaining 2 seconds.
[0260] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on the primary carrier and it is determined that the terminal will skip listening to PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier spacing of all BWPs configured on the primary carrier or the minimum subcarrier spacing of the BWPs activated by the terminal on the primary carrier. It should be noted that the PDCCH listening skip information is valid within its effective duration; outside of its effective duration, the PDCCH listening skip information is invalid. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on the predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.
[0261] In one embodiment, if the PDCCH listening skip information instructs the terminal to skip listening to PDCCH on the primary carrier and determines that the terminal will skip listening to PDCCH on the secondary carrier, then the effective duration of the PDCCH listening skip information can be determined based on the minimum subcarrier interval of all BWPs configured on the primary and secondary carriers, or the minimum subcarrier interval of the BWP activated by the terminal on the primary carrier. As an example, a timer to stop listening is started on the primary carrier. It should be noted that the PDCCH listening skip information is valid within its effective duration; outside of its effective duration, the PDCCH listening skip information is invalid. If the PDCCH listening skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH listening skip information is valid, the terminal will skip listening to PDCCH on the predetermined carrier based on the PDCCH listening skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH listening skip information.
[0262] In one embodiment, if the PDCCH skipping information indicates that the terminal skips PDCCH listening on the primary carrier and initiates a random access procedure on the primary carrier, the terminal will prematurely terminate the skipping of PDCCH listening on the primary carrier. That is, PDCCH skipping will be affected. A timer started on the primary carrier to stop listening will stop, and the primary carrier will enter an active time or active state.
[0263] In one embodiment, if the PDCCH skipping information indicates that the terminal skips listening to the PDCCH on the secondary carrier and initiates a random access procedure on the secondary carrier, the terminal will prematurely terminate skipping the PDCCH listening on the primary carrier. That is, the PDCCH skipping will be affected. Here, prematurely terminating the skipping of PDCCH listening on the primary carrier can be achieved by prematurely terminating a timer set for the primary carrier.
[0264] In one embodiment, if the PDCCH skipping information indicates that the terminal skips listening to the PDCCH on both the primary and secondary carriers and initiates a random access procedure on the secondary carrier, the terminal will prematurely terminate skipping the PDCCH listening on the primary carrier. That is, the PDCCH skipping will be affected. Here, prematurely terminating the skipping of PDCCH listening on the primary carrier can be achieved by prematurely terminating a timer set for the primary carrier.
[0265] In one embodiment, if the PDCCH listening skip information indicates that the terminal skips listening to the PDCCH on the secondary carrier and initiates a random access procedure on the secondary carrier, the terminal will prematurely terminate the skipping of listening to the PDCCH on both the primary and secondary carriers. That is, the PDCCH skipping will be affected. Here, prematurely terminating the skipping of listening to the PDCCH on the primary carrier and / or the secondary carrier can be achieved by prematurely terminating a timer set for the primary and / or secondary carriers.
[0266] In one embodiment, the base station receives auxiliary information sent by the terminal, wherein the auxiliary information is used to assist the base station in sending PDCCH snooping skip information to the terminal.
[0267] In one embodiment, the base station receives auxiliary information reported by the terminal indicating a desire to skip listening. Exemplarily, this auxiliary information indicates the number of secondary carrier groups for which skipping listening is desired. Exemplarily, this auxiliary information indicates that both the primary and secondary carriers are expected to hibernate.
[0268] In one embodiment, the base station receives auxiliary information reported by the terminal indicating the terminal's ability to skip listening. For example, the auxiliary information indicates whether skip listening is supported or not; and / or, the auxiliary information indicates whether skip listening is supported or not for secondary carriers in carrier aggregation; and / or, the auxiliary information indicates whether skip listening is supported or not for both the primary and secondary carriers.
[0269] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0270] like Figure 8 As shown, this embodiment provides a method for skipping monitoring, wherein the method is executed by the terminal and includes:
[0271] Step 81: Receive the PDCCH listening skip information sent by the base station on the main carrier.
[0272] Here, the PDCCH listening skip information instructs the terminal to skip listening to the PDCCH on a predetermined carrier; the predetermined carrier includes at least one of the primary carrier and the secondary carrier.
[0273] In one embodiment, the terminal receives PDCCH snooping skip information sent by the base station on the primary carrier. This PDCCH snooping skip information instructs the terminal to skip snooping on the predetermined carrier. Here, the primary carrier can be a Pcell or a Pscell. Upon receiving the PDCCH snooping skip information, the terminal can skip snooping on the predetermined carrier.
[0274] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0277] And / or,
[0278] At least one secondary carrier group, wherein the secondary carrier group comprises multiple secondary carriers within the same frequency range FR.
[0279] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on at least one secondary carrier. Upon receiving the PDCCH snooping skip information, the terminal will skip snooping on the at least one secondary carrier according to the PDCCH snooping skip information. Here, the at least one secondary carrier can be some or all of the secondary carriers supported by the terminal.
[0280] In one embodiment, the base station sends PDCCH snooping skip information to the terminal, wherein the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on secondary carriers within at least one secondary carrier group.

In one embodiment, the PDCCH skip information indicates: initiate a random access procedure on the secondary carrier, without prematurely terminating the skipping of PDCCH monitoring on the secondary carrier. In one embodiment, the base station sends PDCCH monitoring skip information to the terminal, wherein the PDCCH monitoring skip information indicates that the terminal skips PDCCH monitoring on the secondary carrier. After receiving the PDCCH monitoring skip information, the terminal initiates a random access procedure on the secondary carrier, without prematurely terminating the skipping of PDCCH monitoring on the secondary carrier.
[0283] In one embodiment, the base station sends a PDCCH snooping skip message to the terminal, instructing the terminal to skip PDCCH snooping on the secondary carrier. Upon receiving this message, the terminal initiates a random access procedure on the secondary carrier without prematurely terminating the skipped PDCCH snooping on the secondary carrier. Here, because the terminal is snooping on the primary carrier (RAR), the terminal does not prematurely terminate PDCCH snooping on the secondary carrier, thus not affecting the snooping on the primary carrier.
[0284] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0286] In one embodiment, if the PDCCH snooping skip information instructs the terminal to skip snooping on PDCCH on a secondary carrier within a secondary carrier group, the effective duration of the PDCCH snooping skip information can be determined based on the minimum subcarrier spacing on the BWP configured on the effective secondary carrier group. It should be noted that the PDCCH snooping skip information is valid within its effective duration; it is invalid outside of the effective duration. If the PDCCH snooping skip information is invalid, the terminal will ignore it. Alternatively, if the PDCCH snooping skip information is valid, the terminal will skip snooping on the predetermined carrier based on the PDCCH snooping skip information. In one embodiment, the starting point for the effective duration can be the time when the terminal receives the PDCCH snooping skip information.
