In order to facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be optionally combined with the technical solutions of the embodiments of the present application, and they all belong to the embodiments of the present application. protected range.

AR/VR business

With the rapid development of the mobile Internet, augmented reality (AR) technology and virtual reality (VR) technology are booming. In order to meet the needs of AR technology and VR technology, mobile communication networks need to provide large-bandwidth, low-latency communication services.

For AR business and VR business, in order to improve user experience, business data transmission requires a higher refresh rate. Generally, a refresh rate above 60Hz can bring a better user experience. Typical refresh rate values are 60Hz and 90Hz. , 120Hz, 180Hz, etc. A concept corresponding to refresh rate is cycle. It can be understood that for AR business and VR business, business data transmission has a certain periodicity. When the refresh rate of business data transmission is 60Hz, the corresponding transmission cycle is 16.67ms, such as As shown in Figure 2.

Terminal equipment needs to consume a lot of power while supporting high speed and low latency. How to reduce the power consumption of terminal equipment while meeting business data transmission requirements is an issue that needs to be considered.

PDCCH search space in NR

The terminal equipment performs PDCCH monitoring on PDCCH opportunities concentrated in the PDCCH search space. Here, the PDCCH search space set consists of periodic PDCCH search spaces. The PDCCH search space set is generally configured by the network device to the terminal device through RRC signaling. As an example, the configuration information of the PDCCH search space set includes at least one of the following information:

Search ID: An identifier used to indicate the PDCCH search space set;

Control resource set identifier (controlResourceSetId): An identifier used to indicate the configuration of the control resource set. Here, the configuration of the control resource set is used to configure the time-frequency resources of the PDCCH search space set;

Period of PDCCH search space set: used to indicate the number of time slots of two adjacent PDCCH search spaces in the PDCCH search space set. The period values supported by NR are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 160, 320, 640, 1280, 2560, the unit is time slot.

The offset of the PDCCH search space set within the cycle: used to indicate the time slot difference between the time slot where the starting position of the first PDCCH search space in the PDCCH search space set is located relative to the start time slot of the cycle;

Monitoring duration (Duration) of PDCCH search space set: used to indicate the number of continuous monitoring time slots on each PDCCH search space in the PDCCH search space set;

Monitoring symbols of the PDCCH search space set (monitoringSymbolsWithinSlot): used to indicate the starting symbols of one or more monitoring positions within the monitoring slot;

PDCCH candidates corresponding to the PDCCH search space set: used to indicate the configuration information of the PDCCH candidate;

Type of PDCCH search space set: used to indicate whether the PDCCH search space set is a public search space set or a UE-specific search space set.

For AR services and VR services, in order to match the periodic service transmission characteristics, the terminal equipment can be configured with a PDCCH search space set that is adapted to the transmission period of the service. The terminal equipment monitors the PDCCH at the PDCCH monitoring opportunities in the PDCCH search space, and at other times the terminal equipment can enter the energy-saving state (for example, the terminal equipment can turn off some radio frequencies or baseband equipment to enter a short sleep state). However, in the case of a typical refresh rate, the transmission period of service data does not match the period of the PDCCH search space set supported by the standard. For example, the period values of the PDCCH search space set supported by NR are 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 160, 320, 640, 1280, 2560, and the unit is a time slot. If the subcarrier spacing of 15KHz is used, the length of a single time slot is 1ms, and the period of the PDCCH search space set corresponds to 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 160, 320, 640 ,1280,2560ms. In the case of typical refresh rates, such as 60Hz, 90Hz, 120Hz, and 180Hz, the corresponding service data transmission periods are 16.7ms, 11.1ms, 8.3ms, and 5.6ms respectively.

Therefore, how to solve the problem of matching the period of the PDCCH search space set with the transmission period of service data so that the terminal equipment enters an energy-saving state when there is no service data transmission is a problem that needs to be solved.

To this end, the following technical solutions of the embodiments of the present application are proposed.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.
