[0037] Examples of the present disclosure will now be further described in conjunction with the figures and specific embodiments.

[0038] Exemplary embodiments are described in detail herein, examples of which are illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0039] It should be noted that one embodiment of the present disclosure may include multiple steps, and although these steps are numbered for ease of explanation, these numbers do not limit the execution slots between the steps or the order of execution, and these steps may be performed in any order, and the embodiments of the present disclosure are not limited thereto.

[0040] A DCI including information indicating a PDCCH monitoring adaptation operation can be represented as a PDCCH adaptation DCI (PAD), and a DCI including information indicating a BWP switching can be represented as a BWP switching DCI (BSD).

[0041] After the user equipment receives the PAD, the operation of the user equipment can adopt any of the following: Beh 1: PDCCH skipping is not activated. Beh 1A: Stop PDCCH monitoring (ie, PDCCH skipping) within X time length, and the network device can dynamically indicate the value of X in DCI. Action 2 (Beh 2): Stop monitoring the search spaces in search space set group (SSSG) #1 and SSSG #2 (if this setting exists), and monitor the search space in SSSG #0. Action 2A (Beh 2A): Stop monitoring the search space in SSSG#0 and SSSG#2 (if this setting exists), and start monitoring the search space in SSSG#1. Action 2B (Beh 2B): Stop monitoring the search space in SSSG#0 and SSSG#1, and monitor the search space in SSSG#2 (if this setting exists).

[0042] Conventional communication protocols stipulate that PAD can only be sent before BSD or in the same Monitoring Occasion (MO).

[0043] Then, it is necessary to define the PDCCH monitoring operation in the scene where the user equipment performs BWP switching and receives a PDCCH monitoring adaptation indication.

[0044] An embodiment of the present disclosure provides a channel monitoring method, which is executed by a user equipment. The method may be executed individually or in combination with any other embodiment of the embodiment of the present disclosure. Figure 1 is a flow chart of a channel monitoring method shown by an exemplary embodiment. As shown in Figure 1, the method includes the following steps 101-102:

[0045] In step 101, a first Downlink Control Information (DCI) is received.

[0046] In step 102, after a bandwidth portion (BWP) switching, perform physical downlink control channel (PDCCH) monitoring based on one of a first monitoring scheme, a second monitoring scheme, and a third monitoring scheme.

[0047] The first DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment before the BWP switch.

[0048] In one embodiment, the user equipment receives a PAD before a BWP switch, and performs PDCCH monitoring after a BWP switch based on one of a first monitoring scheme, a second monitoring scheme, and a third monitoring scheme. In one embodiment, the BWP switch is a DCI BWP switch that receives an instruction to perform a BWP switch. In one embodiment, the BWP switch is a timer-based BWP switch.

[0049] In the above embodiment, the user equipment can determine whether to perform PDCCH monitoring based on the PAD received before the BWP switch based on different monitoring manners, thereby solving the problem of in what manner the user equipment should monitor the PDCCH after the BWP switch.

[0050] An embodiment of the present disclosure provides a channel monitoring method, which is executed by a user equipment.

[0052] In step 202, after a bandwidth portion (BWP) switch, a PDCCH monitoring adaptation operation indicated by a first DCI is ignored, the first DCI including information indicating a PDCCH monitoring adaptation operation being received by the user equipment before the BWP switch.

[0053] In one embodiment, the user equipment receives a PAD before the BWP switch, and after the BWP switch, ignores the PAD received before the BWP switch, i.e., does not perform the PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch.

[0054] In one embodiment, the user equipment receives a PAD before the BWP switch, and ignores the PAD received before the BWP switch after the BWP switch, i.e., does not perform a PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch. In response to a search space set group being set in the BWP after the switch, before the PAD is received after the BWP switch, the user equipment monitors a default search space set group. The default search space set group here is defined by a communication protocol, for example, SSSG#0.

[0055] In one embodiment, the user equipment receives a PAD before the BWP switch, and ignores the PAD received before the BWP switch after the BWP switch, i.e., does not perform a PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch. In response to the search space set group not being set in the BWP after the switch, before the PAD is received after the BWP switch, the user equipment monitors the search space set in the BWP after the switch.

[0056] In the above embodiments, the PDCCH monitoring manners adopted by the user equipment all belong to the first monitoring manner.

[0057] In the above embodiment, when performing PDCCH monitoring, the user equipment ignores the PAD received before the BWP switching, so that the user equipment can perform PDCCH monitoring based on the setting of the BWP after the switching.

[0059] In step 301, a first DCI is received.

[0060] In step 302, after a bandwidth portion (BWP) switch, the PDCCH monitoring adaptation operation indicated by the first DCI is ignored.

[0061] In step 303, in response to the existence of a search space set group switching timer and / or a PDCCH skipping timer that is running and associated with the BWP before the BWP switch, the operation of the search space set group switching timer and / or the PDCCH skipping timer is stopped.

[0062] The first DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment before the BWP switch.

[0063] In one embodiment, the user equipment receives a PAD before a BWP switch, and after a BWP switch, ignores the PAD received before the BWP switch, i.e., does not perform a PDCCH monitoring adaptation action indicated by the PAD received before the BWP switch. In a scene where a search space set group switching timer and / or a PDCCH skipping timer are active and associated with the BWP before the BWP switch, the search space set group switching timer and / or the PDCCH skipping timer are stopped from operating.

[0064] In one embodiment, the user equipment receives a PAD before the BWP switch, and ignores the PAD received before the BWP switch after the BWP switch, i.e., does not perform the PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch. In a scene where a search space set group switching timer and / or a PDCCH skipping timer are active and associated with the BWP before the BWP switch, the search space set group switching timer and / or the PDCCH skipping timer are stopped. In response to a search space set group being set in the switched BWP, the default search space set group is monitored before the PAD is received after the BWP switch. The default search space set group here is specified by the communication protocol, for example, SSSG#0.

[0065] In one embodiment, the user equipment receives a PAD before the BWP switch, and ignores the PAD received before the BWP switch after the BWP switch, i.e., does not perform the PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch. In a scene where a search space set group switching timer and / or a PDCCH skipping timer are active and associated with the BWP before the BWP switch, the search space set group switching timer and / or the PDCCH skipping timer are stopped. In response to the search space set group not being set in the BWP after the switch, before the PAD is received after the BWP switch, the search space set in the BWP after the switch is monitored.

[0066] In the above embodiments, the PDCCH monitoring manners adopted by the user equipment all belong to the first monitoring manner.

[0067] In the above embodiment, when performing PDCCH monitoring, the user equipment ignores the PAD received before the BWP switching, so that the user equipment can perform PDCCH monitoring based on the setting of the BWP after the switching.

[0069] In step 401, a first DCI is received.

[0070] In step 402, after a bandwidth portion (BWP) switching, in response to a search space set group being set in the switched BWP, a default search space set group is monitored before a second DCI is received, and in response to a search space set group not being set in the switched BWP, a search space set in the switched BWP is monitored before the second DCI is received.

[0071] The first DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment before the BWP switching, and the second DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment after the BWP switching.

[0072] In one embodiment, the user equipment receives a PAD before a BWP switch, and after the BWP switch, in response to a search space set group being set in the switched BWP, monitors a default search space set group before receiving a PAD after the BWP switch. In one embodiment, the default search space set group is defined by a communication protocol, for example, SSSG#0.

[0073] In one embodiment, the user equipment receives a PAD before a BWP switch, and after the BWP switch, in response to a search space set group not being set in the switched BWP, monitors the search space set in the switched BWP before the PAD is received after the BWP switch.

[0074] In the above embodiments, the PDCCH monitoring manners adopted by the user equipment all belong to the first monitoring manner.

[0075] In the above embodiment, when the user equipment performs PDCCH monitoring, it adopts different PDCCH monitoring methods based on whether a search space set group is set in the BWP after switching.

[0076] An embodiment of the present disclosure provides a channel monitoring method, which is executed by a user equipment.

[0082] In the above embodiment, in a scene where the number of PDCCH skipping durations and the number of search space set groups set in the BWP before and after the BWP switching are the same, the user continues to perform PDCCH monitoring based on the PAD received before the BWP switching. In this way, in a scene where the settings before and after the BWP switching are the same, the PDCCH monitoring adaptation operation before the BWP switching can be continued.

[0083] An embodiment of the present disclosure provides a channel monitoring method, which is executed by a user equipment. The method may be executed individually or in combination with any other embodiment of the embodiment of the present disclosure.

[0089] In the above embodiments, the PDCCH monitoring manners adopted by the user equipment all belong to the second monitoring manner.

[0090] In the above embodiment, in the scene where the number of PDCCH skipping durations and the number of search space set groups set in the BWP before and after the BWP switching are the same, the user equipment continues to perform PDCCH monitoring based on the PAD received before the BWP switching. In this way, in the scene where the settings before and after the BWP switching are the same, the PDCCH monitoring adaptation operation before the BWP switching can be continued, and the operation of the search space set group switching timer and / or the PDCCH skipping timer is not interrupted.

[0091] An embodiment of the present disclosure provides a channel monitoring method, which is executed by a user equipment. The method may be executed individually or in combination with any other embodiment of the present disclosure. The method includes receiving a first DCI; after a bandwidth portion (BWP) switching, in response to a number of PDCCH skipping durations configured in a BWP before the BWP switching and a BWP after the switching being different and / or a number of search space set groups configured in a BWP before the BWP switching and a BWP after the switching being different, ignoring a PDCCH monitoring adaptation operation indicated by the first DCI, and in response to a search space set group being configured in the BWP after the switching, performing a default search space set group configuration before a second DCI is received. and in response to a search space set group not being set in the BWP after the switching, performing the operations of monitoring a space set group and monitoring a search space set in the BWP after the switching before the second DCI is received, wherein the first DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment before the BWP switching, and the second DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment after the BWP switching.

[0092] In one embodiment, the user equipment receives a PAD before a BWP switch, and after the BWP switch, in response to the number of PDCCH skipping durations set in the BWP before the BWP switch and the BWP after the switch being different, or in response to the number of search space set groups set in the BWP before the BWP switch and the BWP after the switch being different, or in response to both the number of PDCCH skipping durations and the number of search space set groups set in the BWP before the BWP switch and the BWP after the switch being different, the user equipment performs the following operations: ignoring the PAD received before the BWP switch, i.e., not performing a PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch; and in response to a search space set group being set in the BWP after the switch, monitoring a default search space set group before a PAD is received after the BWP switch.

In this way, in a scene where the settings before and after the BWP switching are different, the PDCCH monitoring is not performed based on the PAD before the BWP switching, and thus the PDCCH monitoring can be performed based on the settings of the BWP after the switching.

[0096] An embodiment of the present disclosure provides a channel monitoring method, which is executed by a user equipment. The method may be executed individually or in combination with any other embodiment of the present disclosure. The method includes receiving a first DCI; ignoring a PDCCH monitoring adaptation operation indicated by the first DCI in response to a bandwidth portion (BWP) switching in which a number of PDCCH skipping durations set in a BWP before the BWP switching and a BWP after the switching are different and / or a number of search space set groups set in a BWP before the BWP switching and a BWP after the switching are different; monitoring a default search space set group before a second DCI is received in response to a search space set group being set in the BWP after the switching; and monitoring a default search space set group before a second DCI is received in response to a search space set group not being set in the BWP after the switching. and performing the operations of monitoring a search space set in the post-BWP before the BWP is switched and stopping operation of a search space set group switching timer and / or a PDCCH skipping timer in response to the existence of a search space set group switching timer and / or a PDCCH skipping timer that is active and associated with the BWP before the BWP switching, wherein the first DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment before the BWP switching, and the second DCI includes information indicating a PDCCH monitoring adaptation operation and is received by the user equipment after the BWP switching.

[0097] In one embodiment, the user equipment receives a PAD before the BWP switch, and after the BWP switch, in response to the number of PDCCH skipping durations set in the BWP before the BWP switch and the BWP after the switch being different, or in response to the number of search space set groups set in the BWP before the BWP switch and the BWP after the switch being different, or in response to both the number of PDCCH skipping durations and the number of search space set groups set in the BWP before the BWP switch and the BWP after the switch being different, ignores the PAD received before the BWP switch, i.e. does not perform a PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch, and in response to a search space set group being set in the BWP after the switch, monitors a default search space set group before the PAD is received after the BWP switch. In response to the existence of a search space set group switching timer and / or a PDCCH skipping timer that is active and associated with the BWP before the BWP switch, the operation of the search space set group switching timer and / or the PDCCH skipping timer is stopped.

[0098] In one embodiment, the user equipment receives a PAD before a BWP switch, and after the BWP switch, in response to the number of PDCCH skipping durations set in the BWP before the BWP switch and the BWP after the switch being different, or in response to the number of search space set groups set in the BWP before the BWP switch and the BWP after the switch being different, or in response to both the number of PDCCH skipping durations and the number of search space set groups set in the BWP before the BWP switch and the BWP after the switch being different, ignores the PAD received before the BWP switch, i.e. does not perform a PDCCH monitoring adaptation operation indicated by the PAD received before the BWP switch, and in response to no search space set group being set in the BWP after the switch, before the PAD is received after the BWP switch, monitors the search space set in the BWP after the switch before the PAD is received. Also, in response to the existence of a search space set group switching timer and / or a PDCCH skipping timer that is active and associated with the BWP before the BWP switch, stops the operation of the search space set group switching timer and / or the PDCCH skipping timer.

[0099] In the above embodiments, the PDCCH monitoring manners adopted by the user equipment all belong to the second monitoring manner.

[0100] In the above embodiment, in the same scene where at least one of the number of PDCCH skipping durations and the number of search space set groups set in the BWP before the BWP switching and the BWP after the switching is different, the user equipment ignores the PAD received before the BWP switching. In this way, in the scene where the settings before and after the BWP switching are different, the PDCCH monitoring is not performed based on the PAD before the BWP switching, and the search space set group switching timer and / or the PDCCH skipping timer associated with the BWP before the BWP switching is not continuously operated, so that the PDCCH monitoring can be performed based on the settings of the BWP after the switching.
