[0031] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0032] In the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this article indicates that the associated objects before and after are in an "or" relationship.

[0033] The term "a plurality of" that appears in the embodiments of the present application refers to two or more. The descriptions such as the first and the second that appear in the embodiments of the present application are only for schematic and distinguishing the described objects, without an order, and do not represent a special limitation on the number of devices in the embodiments of the present application, and cannot constitute any limitation on the embodiments of the present application. The term "connection" that appears in the embodiments of the present application refers to various connection methods such as direct connection or indirect connection to achieve communication between devices, and the embodiments of the present application do not make any limitation on this.

[0034] The technical solution of the embodiment of the present application can be applied to, for example Figure 1 the example communication system 100 shown in the figure. The example communication system 100 includes a terminal 110 and a network device 120, and the terminal 110 is communicatively connected to the network device 120.

[0035] The terminal in the embodiments of the present application can refer to various forms of UEs, access terminals, user units, user stations, mobile stations, MSs (English: mobile station, Chinese: mobile station), remote stations, remote terminals, mobile devices, user terminals, terminal devices (English: terminal equipment), wireless communication devices, user agents or user devices. The terminal device can also be a cellular phone, a cordless phone, a SIP (English: session initiation protocol, Chinese: session initiation protocol) phone, a WLL (English: wireless local loop, Chinese: wireless local loop) station, a PDA (English: personal digital assistant, Chinese: personal digital processing), a handheld device with wireless communication function, a computing device or other processing devices connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN (English: public land mobile network, Chinese: public land mobile communication network), etc., and the embodiments of the present application do not limit this.

[0036] Refer to Figure 2 , Figure 2 A PDCCH scheduling and monitoring method is provided, which can be executed by a user equipment. The user equipment can be a terminal in a communication system as shown in Figure 1 . Of course, in practical applications, the above user equipment can also be other types of devices, such as Figure 2 shown, including the following steps:

[0037] Step S201, the UE receives a PDCCH with a search space set switching indication;

[0038] The above PDCCH with a search space set switching indication can be a PDCCH configured in DCI and including an indication field for triggering the switching of the search space. By way of example, if the indication field for triggering the switching of the search space is 0, if the UE does not monitor the search space set in group 0, the UE, and stops monitoring the PDCCH of the search space set in group 1 in the next time slot after at least P1 symbols, and starts to monitor the search space set in group 0.

[0039] Of course, the above PDCCH with a search space set switching indication can also be that the UE monitors the PDCCH in the search space set group 0, the UE starts to monitor the search space set in group 1, and stops monitoring the PDCCH of the search space set in group 0 in the next time slot after at least P2 symbols.

[0040] Step S202, after the UE receives the PDCCH with a search space set switching indication, the UE stops monitoring the PDCCH of the search space set of one group among multiple groups, and the UE determines the start monitoring time slot of the search space set of the next group according to the end symbol of the PDCCH;

[0041] Step S203, at the start monitoring time slot, the UE starts to monitor the PDCCH candidates of the search space set of the next group.

[0042] Optionally, the above next group can be the next group of one group among multiple groups. For example, if one group is group 0, the next group can be group 1.

[0043] Optionally, the above multiple groups can be 2 groups or 4 groups. Of course, it can also be other numbers of groups. The present application does not limit the specific number of the above multiple groups. Each group can include one or more time slots. Of course, in practical applications, at least two groups among multiple groups have different numbers of time slots. Taking two groups as an example, group 0 can include 2 time slots, and group 1 can include 4 time slots; of course, in practical applications, the above group 0 can include 1 time slot, and group 1 can include 2 or 4 time slots.

[0044] A group and the next group in this application both represent a search space group, the next search space group.

[0045] After the PDCCH that receives the search space group switching indication according to the technical solution provided by this application stops listening to the PDCCH of the search space set of one group among multiple groups, the UE determines the start listening time slot of the search space set of the next group according to the end symbol of the PDCCH; at the start listening time slot, the UE starts to listen to the PDCCH candidates of the search space set of the next group. Therefore, the technology of this application realizes PDCCH scheduling and listening within multiple time slots, and determines when to perform search space group switching through the search space search switching indication or implicit judgment, realizes PDCCH scheduling and listening within multiple time slots in a timely manner, flexibly realizes PDCCH transmission, and improves network performance.

[0046] In an alternative solution, the UE determines the start listening time slot of the search space set of the next group according to the symbol of the PDCCH, which specifically includes:

[0047] The UE determines the time slot Y of symbol X + P, where X is the number of the end symbol of the PDCCH;

[0048] If it is determined that time slot Y and time slot Y + 1 belong to two time slot groups respectively, it is determined that the start listening time slot of the search space set of the next group is time slot Y + 1; the two time slot groups belong to the search space set of the next group;

[0049] If it is determined that time slot Y and time slot Y + 1 belong to the same time slot group, it is determined that the start listening time slot of the search space set of the next group is the start time slot of the first time slot group of the search space set of the next group after time slot Y. The one time slot group belongs to the search space set of the next group.

[0050] Exemplarily, the length of a time slot group of the search space set of one group can be obtained from higher layer signaling, and this application does not limit the specific signaling form of the higher layer signaling.

[0051] Exemplarily, time slot Y and time slot Y + 1 belonging to two time slot groups respectively can specifically be that time slot Y is a time slot of group 0 and time slot Y is a time slot of group 1. Exemplarily, time slot Y and time slot Y + 1 belonging to one time slot group can specifically be that time slot Y is a time slot of group 0 and time slot Y is also a time slot of group 0.

[0052] In an alternative solution, the UE determines the start listening time slot of the search space set of the next group according to the symbol of the PDCCH, which specifically includes:

[0053] The UE determines the time slot Y of symbol X + P, where X is the number of the end symbol of the PDCCH;

[0054] The UE determines that the starting listening time slot for the search space set of the next group is time slot Y+1.

[0055] Specifically, the above P can be P1 or P2. For the specific values of P1 and P2, refer to the values of Pswitch in Table 10.4-1.

[0056] In an alternative solution, the method further includes:

[0057] Taking time slot Y+1 as the new boundary of the search space set of the next group, and re-partitioning the search space sets of multiple groups.

[0058] Embodiment 1

[0059] Embodiment 1 of the present application provides a PDCCH scheduling and listening method. The implementation scenario of the embodiment of the present application is that, taking two groups as an example for multiple groups of the present application, for convenience, the two groups are named group 0 and group 1. Among them, group 0 contains two time slots. Specifically, slot 0&1 is a time slot group (group 0), and slot 2&3, slot 4&5 are another time slot group (group 1). The method is as Figure 3A shown, and includes the following steps:

[0060] Step S301: The UE receives a PDCCH indicating a search space group switch at symbol 9 of slot 0.

[0061] Step S302: After the UE determines that (9+P) belongs to slot 1, it starts to switch and listen to the PDCCH candidates of the next group (group 1) from slot 2.

[0062] The time slot schematic diagram of the technical solution provided by the embodiment of the present application is as Figure 3B shown. Referring to Figure 3B , the UE can implement PDCCH listening for multiple time slots, and can determine that the starting listening time slot is slot 2, realizing PDCCH scheduling and listening within multiple time slots, and improving network performance.

[0063] Embodiment 2

[0064] Embodiment 2 of the present application provides a PDCCH scheduling and listening method. The implementation scenario of the embodiment of the present application is that, taking two groups as an example for multiple groups of the present application, for convenience, the two groups are named group 0 and group 1. Among them, group 0 contains two time slots. Specifically, slot 0&1 is a time slot group (group 0), and slot 2&3, slot 4&5 are another time slot group (group 1). The method is as Figure 4A shown, and includes the following steps:

[0065] Step S401: The UE receives the PDCCH with a search space set switching indication on symbol 0 of slot 0;

[0066] After the UE determines that (0 + P) belongs to slot 0, since slot 1 and slot 0 belong to the same time slot group, the UE starts to switch and monitor the PDCCH candidates of the next group (group 1) from slot 2.

[0067] The time slot schematic diagram of the technical solution provided by the embodiment of the present application is as Figure 4B shown. Refer to Figure 4B , the UE can implement PDCCH monitoring in multiple time slots, and can determine that the time slot for starting monitoring is slot 2, realizing PDCCH scheduling and monitoring within multiple time slots, and improving network performance.

[0068] Optionally, the above step S402 can also be replaced by step S402-1.

[0069] Step S402-1: After the UE determines that (0 + P) belongs to slot 0, it starts to switch and monitor the PDCCH candidates of the next group (group 1) from slot 1, and uses slot 1 as the new boundary of group 1, and re-divides group 0 and group 1. The time slot schematic diagram of its technical solution is as Figure 4C shown. Refer to Figure 4C , starting to monitor at slot 1, after re-division, slot 1, slot 2, slot 3, and slot 4 are group 1. Re-dividing multiple groups can reduce the power overhead of the PDCCH, reduce the complexity of hardware implementation, and improve the efficiency of search space set switching.

Among them, group 0 contains two time slots. Specifically, slot 0&1 is a time slot group (group 0), and slot 2&3, slot 4&5 are another time slot group (group 1). The method is as Figure 5A shown and includes the following steps:

[0072] Step S501: The UE receives the PDCCH with a search space set switching indication on symbol 2 of slot 4;

[0073] Step S502: After the UE determines that (2 + P) belongs to slot 4, since slot 4 and slot 5 belong to the same time slot group, the UE starts to switch and monitor the PDCCH candidates of the next group (group 0) from slot 6.

[0074] The time slot schematic diagram of the technical solution provided by the embodiment of the present application is as Figure 5B shown. Refer to Figure 5B , the UE can implement PDCCH monitoring in multiple time slots, and can determine that the starting monitoring time slot is slot 6, realizing PDCCH scheduling and monitoring in multiple time slots, and improving network performance.

[0075] Step S502-1: After the UE determines that (2 + P) belongs to slot 4, it starts switching from slot 5 to monitor the PDCCH candidates of the next group (group 0), and uses slot 5 as the new boundary of group 0, and re-divides group 0 and group 1. The time slot schematic diagram of its technical solution is as Figure 5C shown. Refer to Figure 5C , starting to monitor at slot 5, after re-division, slot 5 and slot 6 are group 0.
