AI Technical Summary
The existing PDCCH monitoring mechanism in NR systems lacks flexibility, leading to unnecessary complexity and power consumption in terminal devices, particularly in multi-beam systems where uniform monitoring is not always required.
The network device configures PDCCH transmission resources hierarchically at both time slot and symbol levels, allowing the terminal device to selectively monitor PDCCH only in specific time slots or symbols, reducing unnecessary monitoring and power consumption.
This approach enables more flexible PDCCH monitoring, reducing power consumption in terminal devices by allowing them to skip monitoring in non-essential time slots or symbols, thus optimizing resource utilization and power efficiency.

Abstract
Description

[0001] The present application relates to the field of communications, and more particularly to wireless communication methods, network devices and terminal devices. [Background technology]
[0002] In a New Radio (NR) system, a physical downlink control channel (PDCCH) is transmitted in a resource control set (CORESET). At present, a terminal device can receive a PDCCH by uniformly monitoring the CORESET. However, such a CORESET monitoring mechanism is insufficient in flexibility. In some cases, for example, in a multi-beam system, a terminal device does not need to always monitor the CORESET at a predetermined frequency. In this case, uniform monitoring of the CORESET would result in unnecessary extra complexity and power consumption of the terminal device. Therefore, how to flexibly configure a PDCCH monitoring scheme is one of the problems that needs to be solved as soon as possible. Summary of the Invention [Problem to be solved by the invention]

[0054] Preferably, the first setting information is specifically used to indicate the period in which the first time domain unit appears, or the first setting information is specifically used to indicate the time domain position of the at least one first time domain unit within the first time period.
[0055] Preferably, when the first setting information indicates the at least one first time domain unit by a time domain position within a first time period, the time domain position within the first time period includes a set of time domain positions of all first time domain units within the first time period.

[0058] Preferably, the second setting information is specifically used to indicate the period of appearance of the second time domain unit, or the second setting information is specifically used to indicate the time domain position of the at least one second time domain unit in the first time domain unit.

[0062] For example, as shown in Fig. 3, a network device indicates the period in which a time slot including a first resource (CORESET or Search Space) appears using first setting information, and indicates the period in which a start symbol of the first resource appears within one time slot using second setting information. As shown in Fig. 3, among time slots 0, 1, and 2, only time slot 0 includes the first resource, and among time slots 3, 4, and 5, only time slot 3 includes the first resource, i.e., one time slot includes the first resource out of every three time slots, and in each time slot, symbol 0, symbol 2, symbol 4, and symbol 6 are the start symbols of the first resource, i.e., one start symbol of the first resource out of every two symbols.

That is, out of every three time slots, there is one time slot that includes the first resource, and in each time slot, the start symbols of the two first resources are the first symbol and the fourth symbol, respectively.
[0065] Preferably, the network device indicates, in the first setting information, a time domain position of the at least one first time domain unit within a first time period, and indicates, in the second setting information, a period in which the second time domain unit appears.
[0066] For example, as shown in Fig. 5, the network device indicates, in the first configuration information, which time slots include the first resource (control resource set or search space) within a certain time period, and indicates, in the second configuration information, the period in which the start symbol of the first resource appears within one time slot. Specifically, as shown in Fig. 5, among time slots 0, 1, and 2, time slots 0 and 1 include the first resource, and among time slots 3, 4, and 5, time slots 3 and 4 include the first resource, i.e., the top two time slots of every three time slots include the first resource, and in each time slot, symbol 0, symbol 2, symbol 4, and symbol 6 are the start symbols of the first resource, i.e., one of every two symbols is the start symbol of the first resource.
[0067] Preferably, the network device indicates, in the first setting information, a time domain position of the at least one first time domain unit within a first time period, and indicates, in the second setting information, a time domain position of the at least one second time domain unit in the first time domain unit.
[0068] For example, as shown in Fig. 6, the network device indicates which time slots within a certain period include a CORESET using first setting information, and indicates which symbol within one time slot is the start symbol of the CORESET using second setting information. Specifically, as shown in Fig. 6, among time slots 0, 1, and 2, time slots 0 and 1 include the first resource, and among time slots 3, 4, and 5, time slots 3 and 4 include the first resource, that is, among every third time slot, the top two time slots include the first resource, and in each time slot, there are two CORESETs starting from the first symbol and the fourth symbol, respectively.
[0069] 220, the network equipment transmits the physical downlink control channel to the terminal device on the first resource.
[0070] Therefore, in the wireless communication method of the embodiment of the present application, the network device hierarchically configures the first resource for transmitting the physical downlink control channel according to the first configuration information and the second configuration information, thereby realizing more flexible PDCCH monitoring, so that the terminal device does not need to monitor the PDCCH in the first resource in each time slot, and further reduces the power consumption of the terminal device.
[0071] Furthermore, the network device indicates in the first setting information the period in which the first time domain unit appears or the time domain position of at least one first time domain unit within the first time period, thereby realizing flexible setting at the time slot level and meeting various delay requirements.
[0072] Furthermore, the network device indicates in the second setting information the period of appearance of the second time domain unit or the time domain position of at least one second time domain unit in the first time domain unit, thereby realizing flexible setting of the symbol level and meeting various delay requirements.
