Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a method for reducing physical downlink control channel monitoring, user equipment, and a storage medium. Background Art

[0002] The battery consumption of user equipment (UE) is an important aspect of user experience, which will affect the user experience of 5G UE and 5G services. To this end, some technologies for indicating UE status changes are introduced in the 5G system, so that the UE can enter a power-saving state under appropriate conditions to save energy. The switching of UE status involves changes in multiple configurations, including switching of bandwidth units (BandWidth Part, BWP) (switching to a smaller BWP), switching of physical downlink control channel (Physical Downlink Control Channel, PDCCH) detection period (switching to a larger period), skipping of some PDCCHs (PDCCH monitoring skipping) and cross-slot scheduling with a minimum scheduling interval greater than 0. The signaling that triggers these configuration changes is usually carried by downlink control information (DCI).

[0003] In the standardization and technical research for 5G NR Release 16, energy-saving technologies based on cross-slot scheduling were completed. In the upcoming research for Release 17, technologies to reduce PDCCH monitoring will be a key focus. Existing proposed methods for reducing PDCCH monitoring include switching the PDCCH monitoring configuration (such as switching search space sets or switching the PDCCH monitoring period, i.e., individual parameters within a specific SS set) and PDCCH skipping. Both solutions are likely to be adopted in future standardization processes, meaning that UEs will support both switching the PDCCH monitoring configuration and PDCCH skipping.

[0004] The switching of the PDCCH monitoring configuration can be triggered by a specific DCI, and PDCCH skipping can also be indicated by a specific DCI. Therefore, the UE may receive both the PDCCH monitoring configuration switching indication and the PDCCH skipping indication at the same time. In this case, the UE cannot determine how to execute the base station's instructions, which may lead to scheduling errors in the base station. Summary of the Invention

[0024] Figure 2 This is a schematic diagram of a PDCCH monitoring configuration with different durations in the prior art;

[0025] Figures 3 to 8 is a schematic diagram of six SS set switching in an embodiment of the present invention;

[0026] Figure 9 It is a structural diagram of a user equipment in an embodiment of the present invention. DETAILED DESCRIPTION

[0027] As described above, the user equipment may receive an indication of switching the PDCCH monitoring configuration and an indication of PDCCH skipping at the same time. However, in the prior art, there is no solution for processing the situation in which the user equipment receives an indication of switching the PDCCH monitoring configuration and an indication of PDCCH skipping at the same time. There are two possible solutions: 1) the user equipment does not want to receive an indication of switching the PDCCH monitoring configuration and an indication of PDCCH skipping at the same time; 2) define the priority of the signaling, such as defining that the signaling carrying the switching PDCCH monitoring configuration corresponds to a high priority, and the signaling carrying the indication of PDCCH skipping corresponds to a low priority.

[0028] However, the above solution 1) will affect the scheduling flexibility of the base station. For the above solution 2), if the user equipment only performs one of switching the PDCCH monitoring configuration and PDCCH skipping, the scheduling flexibility of the base station is limited, and the other signaling is discarded, resulting in wasted base station overhead.

[0029] In an embodiment of the present invention, when it is detected that the first indication information and the second indication information are received in the same time slot, PDCCH skipping can be performed first and then the PDCCH monitoring configuration can be switched; the PDCCH monitoring configuration can be switched first and the duration of the switched PDCCH monitoring configuration can be adjusted according to the duration of the PDCCH skipping; or whether to switch the PDCCH monitoring configuration can be determined according to the duration of the PDCCH skipping. The above solution enables the UE to process the switching of the PDCCH monitoring configuration and the PDCCH skipping received at the same time, thereby avoiding scheduling errors and waste of overhead by the base station.

[0030] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] The embodiment of the present invention provides a method for reducing PDCCH monitoring, referring to Figure 1 , the following is a detailed description through specific steps.

[0032] Step S101: Determine whether first indication information and second indication information are detected.

[0033] In a specific implementation, the first indication information may be used to instruct the switching of the PDCCH monitoring configuration, that is, switching the PDCCH monitoring configuration. In the embodiment of the present invention, switching the PDCCH monitoring configuration may be switching the PDCCH monitoring period.

[0034] In a specific implementation, the second indication information may be used to instruct to skip monitoring of the PDCCH, that is, to instruct to skip PDCCH.

[0035] In a specific implementation, detecting the first indication information and the second indication information may mean that the user equipment receives the first indication information and the second indication information simultaneously, that is, the user equipment receives the first indication information and the second indication information in the same time slot. If the user equipment detects that the first indication information and the second indication information are received in the same time slot, the user equipment may execute step S102.

[0036] Step S102: Execute a predetermined operation.

[0037] In a specific implementation, the predetermined operation may include any one of the following: first executing the second operation according to the second indication information, and then executing the first operation according to the first indication information; executing the first operation according to the first indication information, and determining the duration of the first operation according to the second indication information; determining whether to execute the first operation indicated by the first indication information according to the second indication information.

[0038] In the embodiment of the present invention, the first operation may be monitoring the PDCCH according to the switched monitoring configuration, and the second operation may be not monitoring the PDCCH within N time units, where N may be indicated by the second indication information.

[0039] In practical applications, switching the PDCCH monitoring configuration involves switching search space sets. This switching refers to the user equipment monitoring the PDCCH according to different search space sets (SS sets). The SS set contains information such as the PDCCH monitoring period and time domain offset. Typically, switching the SS set represents a switch in the PDCCH monitoring period, allowing the user equipment to monitor the PDCCH at a longer or shorter period based on service characteristics or reception requirements.

[0040] In addition, the PDCCH monitoring configuration switch can also switch the value of one or more parameters in the search space set, such as switching the value of the PDCCH monitoring period in the search space set. At this time, the terminal still monitors the PDCCH according to the search space set configuration, but the PDCCH monitoring period has changed.

[0041] For example, when the received data is relatively sparse, the user equipment can switch to a larger PDCCH monitoring period, thereby reducing the PDCCH monitoring density and lowering the energy consumption of the user equipment. For another example, if the user equipment is currently performing a service with high latency requirements, it can switch to a smaller PDCCH monitoring period.

[0042] Existing protocols support only two types of SS set switching in the New Radio Unlicensed Spectrum (NR-U) spectrum: switching between sparse and dense PDCCH monitoring. One is the default SS set, typically designated as SS set index 0; the other is a functional SS set, typically designated as SS set index 1. When switching from SS set 0 to SS set 1, a timer is started. The timer's duration is configured by higher layers. Upon expiration, the system switches back to SS set 0.

[0043] Reference Figure 2 , a schematic diagram of PDCCH monitoring periods of different lengths in the prior art is given. Figure 2 In the example, the PDCCH monitoring period configured for SS set 0 is 2 time slots. In time slot n, the user equipment receives an instruction to switch the PDCCH monitoring period and switches to SS set 1. The PDCCH monitoring period configured for SS set 1 is 1 time slot.

[0044] In a specific implementation, after receiving the first indication information, the user equipment may determine to perform SS set switching.

[0045] In an embodiment of the present invention, the first indication information may be a specific DCI format detected by blind detection, such as DCI format1-1; the first indication information may also indicate switching for the DCI in a dedicated SS set, and the DCI in the dedicated SS set may be DCI format 2-0 or a group common DCI of other formats; the first indication information may be the DCI detected in a given SS set, such as DCI of any format detected in SS set 1; the first indication information may be a DCI of a specific format detected in a given search space set, such as DCI format 1-1 detected in SS set 1; the first indication information may also be an indication in a certain field in the DCI, used to indicate SS set switching.

[0046] It should be noted that, in specific applications, the first indication information may also be in other formats, or may be carried by other information, which will not be elaborated in the embodiment of the present invention.

[0047] In an embodiment of the present invention, the second indication information may be a specific DCI format detected by blind detection, such as DCI format1-1; the second indication information may also indicate switching for the DCI in a dedicated SS set, and the DCI in the dedicated SS set may be DCI format 2-0 or a group common DCI of other formats; the second indication information may be the DCI detected in a given SS set, such as DCI of any format detected in SS set 1; the second indication information may be a DCI of a specific format detected in a given search space set, such as DCI format 1-1 detected in SS set 1; the second indication information may also be an indication in a certain field in the DCI, used to indicate SS set switching.

[0048] It should be noted that, in specific applications, the second indication information may also be in other formats, or may be carried by other information, which will not be elaborated in the embodiment of the present invention.

[0049] In a specific implementation, the first indication information and the second indication information may be carried by the same DCI format or by different DCI formats.

[0050] In a specific implementation, if it is determined that the first indication information and the second indication information are received, PDCCH skipping may be performed first, and then the PDCCH monitoring configuration may be switched. In an embodiment of the present invention, if it is determined that the first indication information and the second indication information are received in the same time slot, PDCCH skipping may be performed first, and then the PDCCH monitoring configuration may be switched.

[0051] Specifically, the user equipment first performs PDCCH skipping and then switches the PDCCH monitoring configuration after N time units. The duration corresponding to the N time units is the duration of PDCCH skipping, which can be pre-configured by the upper layer and indicated by the second indication information. For example, the upper layer configures four durations, and the second indication information indicates one of them; or the upper layer configures one duration, and the second indication information triggers this duration. That is, the second indication information indicates skipping, and the skipping duration is the duration configured by the upper layer.

[0052] Take the PDCCH monitoring configuration as an example, refer to Figure 3 and Figure 4 , respectively give two SS set switching schematic diagrams in the embodiments of the present invention. Figure 3 and Figure 4 In the SS set 0 configuration, the user equipment initially monitors the PDCCH. Figure 3 In the example, the PDCCH monitoring period configured in SS set 0 is a larger period (2 time slots), and the PDCCH monitoring period configured in SS set 1 is a shorter period (1 time slot). Figure 4 In the example, the PDCCH monitoring period configured by SS set 0 is a short period (1 time slot), and the PDCCH monitoring period configured by SS set 1 is a longer period (2 time slots).

[0053] A first indication message indicating a monitoring configuration switch is received in time slot n, and a second indication message indicating PDCCH skipping is received in time slot n. The duration of N time units corresponds to 5 time slots. After 5 time slots, the terminal switches to SS set 1. If a timer exists for SS set 1 and the higher-layer configured timer is m time slots (or milliseconds, or subframes, the time unit is not limited here), the terminal monitors PDCCH according to SS set 1 for m time slots.

[0054] In a specific implementation, if it is determined that the first indication information and the second indication information are received, the PDCCH monitoring configuration can be switched first, and the PDCCH can be monitored according to the switched monitoring configuration (such as the switched PDCCH monitoring period), and the duration of the switched PDCCH monitoring configuration can be adjusted according to the duration of PDCCH skipping, such as adjusting the duration of the switched PDCCH monitoring period according to the duration of PDCCH skipping.

[0055] In the embodiment of the present invention, after the PDCCH monitoring configuration is switched, the duration of the switched PDCCH monitoring configuration is adjusted to the difference between the initial duration of the switched PDCCH monitoring configuration and the duration of PDCCH skipping.

[0056] For example, when switching from SS set 0 to SS set 1, the initial duration of SS set 1 is the timer duration pre-configured by the upper layer. Assuming that the timer duration pre-configured by the upper layer for SS set 1 is Timer and the duration of PDCCH skipping is duration, the duration of the PDCCH monitoring configuration after switching is: Timer - duration.

[0057] If the timer duration is 10 time slots and skipping is 5 time slots, the duration of monitoring PDCCH according to the configuration of SS set1 is 5 time slots. After 5 time slots, the state of monitoring PDCCH according to the configuration of SS set0 is returned to.

[0058] Take the PDCCH monitoring configuration as an example, refer to Figure 5 and Figure 6 , provides schematic diagrams of two more SS set switching in an embodiment of the present invention. Figure 5 and Figure 6 In the SS set 0 configuration, the user equipment initially monitors the PDCCH. Figure 5 In the example, the PDCCH monitoring period configured in SS set 0 is a larger period (2 time slots), and the PDCCH monitoring period configured in SS set 1 is a shorter period (1 time slot). Figure 6 In the example, the PDCCH monitoring period configured by SS set 0 is a short period (1 time slot), and the PDCCH monitoring period configured by SS set 1 is a longer period (2 time slots).

[0059] Depend on Figure 5 and Figure 6It can be seen that the timing duration corresponding to SS set 1 is adjusted to Timer-duration. In other words, the sum of the timing duration corresponding to SS set 1 after adjustment and the duration of PDCCH skipping is equal to the timing duration corresponding to SS set 1 configured by the upper layer before adjustment.

[0060] In a specific implementation, if it is determined that the first indication information and the second indication information are received in the same time slot, it may be further determined whether to switch the PDCCH monitoring configuration according to the duration of the PDCCH skipping.

[0061] In an embodiment of the present invention, if the duration of PDCCH skipping is greater than 0, that is, N indicated by the second indication information is greater than 0, the PDCCH monitoring configuration is not switched; if the duration of PDCCH skipping is equal to 0, that is, N indicated by the second indication information is equal to 0, the PDCCH monitoring configuration is switched.

[0062] Reference Figure 7 and Figure 8 , respectively provide two more SS set switching schematic diagrams in the embodiments of the present invention.

[0063] Figure 7 In the example, the user equipment initially monitors the PDCCH with the configuration of SS set 0. Upon receiving the first indication message and the second indication message in time slot n, where the first indication message indicates / triggers a switch in the monitoring configuration and the second indication message indicates that the duration of PDCCH skipping is greater than 0, the user equipment does not switch the SS set and continues to monitor the PDCCH with the configuration of SS set 0 after time slot n.

[0064] Figure 8 In the example, the user equipment initially monitors the PDCCH in SS set 0. In time slot n, if the user equipment receives a first indication message and a second indication message, where the first indication message indicates / triggers a monitoring configuration switch and the second indication message indicates that the PDCCH skipping duration is equal to 0, the user equipment switches to SS set 1. After the timer reaches a preset duration, the user equipment switches from SS set 1 to SS set 0.

[0065] It should be noted that the unit of the duration of PDCCH skipping is not limited to time slots, but may also be seconds, subframes, frames, milliseconds, microseconds, mini-time slots, symbols, etc.

[0066] In summary, the method for reducing PDCCH monitoring provided by the embodiment of the present invention enables the UE to process the switching and PDCCH skipping of the switching PDCCH monitoring configuration received simultaneously, thereby avoiding waste of base station overhead and avoiding scheduling errors and waste of overhead of the base station.
