As an example, each first downlink signaling received by the terminal device includes monitoring self-adjustment indication information, and each monitoring self-adjustment indication information is at least used to indicate the PDCCH monitoring skip time interval corresponding to at least one search space set relevant information.

The at least one first downlink signaling received by the terminal device may be the same signaling or different signaling, which is not limited here.

Wherein, each monitoring self-adjustment instruction information is used to indicate the relevant information of the PDCCH monitoring skip time interval corresponding to at least one search space set, that is, to indicate the corresponding PDCCH monitoring hop when the terminal device performs PDCCH monitoring in at least one search space set. Information about the elapsed time interval.

Wherein, the related information of the PDCCH monitoring skip time interval indicated by each monitoring self-adjustment instruction information may be the same or different, which is not limited here.

In some feasible implementation manners, when at least one target PDCCH monitoring skip time interval is determined based on the monitoring self-adjustment indication information included in at least one first downlink signaling, the monitoring time interval included in each first downlink signaling may be determined. The PDCCH monitoring skip time interval corresponding to the self-adjustment indication information is determined from the PDCCH monitoring skipping time interval corresponding to each first downlink signaling to determine at least one target PDCCH monitoring skipping time interval.

Wherein, DCI format x_1, DCI format x_2 or DCI format 2_x is an abbreviation for a certain type of DCI, where x refers to a value, for example, DCI format x_1 is any DCI in DCI format 0_1, DCI format 1_1 or DCI format 2_1.

Wherein, the DCIs with different DCI formats may also be DCIs with different cyclic redundancy check (Cyclic Redundancy Check, CRC) scrambled radio network temporary identifiers (Radio Network Tempory Identity, RNTI).

Wherein, the DCIs carrying different information may be DCI signaling with different purposes, for example, a service identifier configured by a network device may indicate that the DCIs carrying different information are used for service transmission of different services.

In addition, DCI formats of DCI1 and DCI2 may be the same or different, which is not limited here.

The terminal device may determine the PDCCH monitoring skip time interval corresponding to at least one search space set by using a multiple of the second duration corresponding to the relevant information indicated by the monitoring self-adjustment indication information included in the first downlink signaling.

Wherein, the PDCCH monitoring skip time intervals corresponding to the monitoring self-adjustment instruction information included in each first downlink signaling may be the same or different. For example, the monitoring self-adjustment instruction information included in different first downlink signaling may correspond to the same first time length or a multiple of the second time length, or may correspond to different first time lengths or multiples of the second time length. This is not limited.

As an example, the terminal device receives 3 first downlink signalings, and each first downlink signaling includes at least the self-monitoring information used to indicate the PDCCH monitoring skip time interval corresponding to at least one search space set. Adjustment instruction information, the multiple of the second duration included in the relevant information corresponding to the monitoring self-adjustment instruction information included in each first downlink signaling is {1, 2, 4}, and the second duration is when the terminal device The PDCCH monitoring period corresponding to the at least one search space set when at least one search space set performs PDCCH monitoring.

As an example, before at least one target search space set performs PDCCH monitoring, the terminal device successively receives two pieces of monitoring self-adjustment indication information including at least relevant information indicating the PDCCH monitoring skip time interval corresponding to at least one search space set. DCIs are respectively DCIs of the DCI format x_1 and DCI format x_2, and the PDCCH monitoring skip time intervals corresponding to the monitoring self-adjustment indication information included in each DCI are T3 and T4 respectively. The terminal device can determine the PDCCH monitoring skip time interval T3 corresponding to the monitoring self-adjustment indication information contained in the DCI format x_1 received earlier as the target PDCCH monitoring skipping time interval, or use the last received DCI format x_2 The PDCCH monitoring skip time interval T4 corresponding to the monitoring self-adjustment indication information included in the DCI is determined as the target PDCCH monitoring skipping time interval.

Wherein, the terminal device determines the signaling priority of the DCI in the DCI format x_1 and the DCI format x_2 through the priority identifier configured by the network device. The terminal device can determine the PDCCH monitoring skip time interval T7 corresponding to the monitoring self-adjustment indication information included in the DCI with the highest priority as the target PDCCH monitoring skip time interval, or set the monitoring self-adjustment indication information included in the DCI with the lowest priority The corresponding PDCCH monitoring skip time interval T8 is determined as the target PDCCH monitoring skip time interval.
