Description

Method for reducing physical downlink control channel monitoring, user equipment and storage medium
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method for reducing physical downlink control channel monitoring, a user equipment, and a storage medium.
Background
Battery power consumption of a User Equipment (UE) is an important aspect of the User experience, which will affect the usage experience of 5G UEs and 5G services. For this reason, some techniques for indicating a UE status change are introduced in the 5G system so that the UE can enter a power saving state under appropriate conditions to save power. The switching of the UE state involves various configuration changes, including switching of a BandWidth unit (BWP) (switching to a smaller BWP), switching of a Physical Downlink Control Channel (PDCCH) detection period (switching to a larger period), skipping monitoring of a Part of the PDCCH (PDCCH monitoring blanking) and cross-slot scheduling (cross-slot scheduling) with a minimum scheduling interval greater than 0, and the like, and signaling triggering these configuration changes is generally carried by Downlink Control Information (DCI).
In the standard technical research of 5G NR Release 16 version, the energy-saving technical part based on cross-slot scheduling is completed. In the future research on Release 17, a technique for reducing the PDCCH monitoring will be considered as one of the techniques discussed with great importance. The currently proposed method for reducing PDCCH monitoring mainly includes a monitoring configuration for switching PDCCH (e.g., switching search space set, or a monitoring period for switching PDCCH, i.e., individual parameters in a certain SS set) and PDCCH skiping, which may be adopted in the future standardization process, i.e., UE supports both the monitoring configuration for switching PDCCH and the PDCCH skiping.
The switching of the monitoring configuration of the PDCCH may be triggered by a specific DCI, and PDCCH blanking may also be indicated by the specific DCI. Therefore, the UE may receive the switching indication of the monitoring configuration of the PDCCH and the indication of PDCCH skiping at the same time, and at this time, the UE cannot determine how to perform the indication of the base station, thereby causing a scheduling error of the base station.

Detailed Description
As described above, the ue may receive the instruction to switch the PDCCH monitoring configuration and the instruction to PDCCH skipping at the same time, however, there is no scheme in the prior art to process that the ue receives the instruction to switch the PDCCH monitoring configuration and the instruction to PDCCH skipping at the same time. Two possible solutions are: 1) the user equipment does not want to receive the instruction of switching the PDCCH monitoring configuration and the instruction of PDCCH skiping at the same time; 2) and defining the priority of signaling, for example, defining that the signaling for bearing the switching PDCCH monitoring configuration corresponds to high priority, and the signaling for bearing the indication of PDCCH skiping corresponds to low priority.
However, with the above scheme 1), the scheduling flexibility of the base station may be affected. With the above scheme 2), if the user equipment performs only one of the PDCCH monitoring configuration and PDCCH puncturing, scheduling flexibility of the base station is limited, and another signaling is discarded to cause the overhead of the base station to be wasted.
In the embodiment of the invention, when detecting that the first indication information and the second indication information are received in the same time slot, the PDCCH skipping can be executed first, and then the PDCCH monitoring configuration is switched; or switching the PDCCH monitoring configuration first, and adjusting the time length of the switched PDCCH monitoring configuration according to the skipping duration of the PDCCH; or determining whether to switch the PDCCH monitoring configuration according to the duration of PDCCH skipping. By the scheme, the UE can process the switching and PDCCH skipping of the switching PDCCH monitoring configuration received at the same time, and scheduling errors and waste of expenses of the base station are avoided.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
An embodiment of the present invention provides a method for reducing PDCCH monitoring, which is described in detail with reference to fig. 1 through specific steps.
Step S101, it is determined that the first indication information and the second indication information are detected.
In a specific implementation, the first indication information may be used to indicate the monitoring configuration switching of the PDCCH, that is, to switch the monitoring configuration of the PDCCH. In the embodiment of the present invention, the monitoring configuration for switching the PDCCH may be a monitoring period for switching the PDCCH.
In a specific implementation, the second indication information may be used to indicate that monitoring of PDCCH is skipped, i.e., to indicate PDCCH skipping (skiping).
In a specific implementation, the detecting of the first indication information and the second indication information may be that the ue receives the first indication information and the second indication information at the same time, that is, the ue receives the first indication information and the second indication information in the same timeslot. If the ue detects that the first indication information and the second indication information are received in the same timeslot, the ue may perform step S102.
In step S102, a predetermined operation is performed.
In a specific implementation, the predetermined operation may include any one of: executing a second operation according to the second indication information, and then executing a first operation according to the first indication information; executing a first operation according to the first indication information, and determining the duration of the first operation according to the second indication information; and determining whether to execute the first operation indicated by the first indication information according to the second indication information.
In this embodiment of the present invention, the first operation may be to monitor the PDCCH according to the monitoring configuration after the handover, the second operation may be to not monitor the PDCCH in N time units, and N may be indicated by the second indication information.
In practical applications, it is known that PDCCH monitoring configuration switching includes switching of search space sets (search space set switching). The switching of the Search Space set refers to that the user equipment monitors the PDCCH according to configuration of different Search Space sets (SS sets), wherein the SS set includes information such as a PDCCH monitoring period and a time domain offset value. In general, the SS set handover can represent PDCCH monitoring period handover, so that the ue can monitor the PDCCH according to a larger or smaller period according to the traffic characteristics or the reception requirement.
In addition, the PDCCH monitoring configuration switching may also be a value of one parameter or a plurality of parameters in the switching search space set, for example, a value of a PDCCH monitoring period in the switching search space set, and at this time, the terminal still monitors the PDCCH according to the search space set configuration, but the PDCCH monitoring period has been changed.
For example, when the received data is sparse, the ue may switch to a larger PDCCH monitoring period, thereby reducing the monitoring density of the PDCCH and reducing the power consumption of the ue. In another example, if the service currently performed by the ue has a higher requirement for delay, the ue may switch to a smaller PDCCH monitoring period.
As known from the existing protocols, in the new unlicensed spectrum (NR-U), only two SS set handovers are supported, which generally refer to the handover between sparse (sparse) PDCCH monitoring and dense (dense) PDCCH monitoring, one of which is a default SS set, and is generally denoted as SS set index 0; the other is a functional SS set, commonly denoted as SS set index 1. When SS set0 is switched to SS set1, a timer is started, the timing duration of the timer is configured by a high layer, and the timer is switched to SS set0 again after the timing duration of the timer is overtime.
Referring to fig. 2, a schematic diagram of PDCCH monitoring periods of different durations in the prior art is given. In fig. 2, the PDCCH monitoring period configured by SS set0 is 2 slots, and in slot n, the user equipment receives an indication of switching the PDCCH monitoring period, and switches to SS set1, and the PDCCH monitoring period configured by SS set1 is 1 slot.
In a specific implementation, the user equipment may determine to perform SS set handover after receiving the first indication information.
In this embodiment of the present invention, the first indication information may be a specific DCI format detected in a blind manner, such as DCI format 1-1; the first indication information may also indicate handover for DCI in the dedicated SS set, where the DCI in the dedicated SS set may be DCI format 2-0, or may be group common DCI in other formats; the first indication information may be DCI detected in a given SS set, e.g., DCI of an arbitrary format detected in SS set 1; the first indication information may be that DCI of a specific format is detected for a given search space set, e.g., DCI format 1-1 detected in SS set 1; the first indication information may also be an indication in a certain domain in DCI for indicating SS set handover.
It should be noted that, in a specific application, the first indication information may also be in other formats or may be carried by other information, which is not described in detail in this embodiment of the present invention.
In this embodiment of the present invention, the second indication information may be a specific DCI format detected in a blind manner, such as DCI format 1-1; the second indication information may also indicate that the handover is indicated by DCI in the dedicated SS set, and the DCI in the dedicated SS set may be DCI format 2-0 or group common DCI in other formats; the second indication information may be DCI detected in a given SS set, e.g., DCI of an arbitrary format detected in SS set 1; the second indication information may be that DCI of a particular format is detected for a given set of search spaces, e.g., DCI format 1-1 detected in SS set 1; the second indication information may also be an indication in one of the DCI domains for indicating SS set handover.
It should be noted that, in a specific application, the second indication information may also be in other formats or may be carried by other information, which is not described in detail in this embodiment of the present invention.
In a specific implementation, the first indication information and the second indication information may be carried by the same DCI format or may be carried by different DCI formats.
In a specific implementation, if it is determined that the first indication information and the second indication information are received, the PDCCH skiping may be performed first, and then the PDCCH monitoring configuration may be switched. In the 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, the PDCCH skiping may be performed first, and then the PDCCH monitoring configuration may be switched.
Specifically, the ue first performs PDCCH blanking and switches PDCCH monitoring configuration after N time units have elapsed. The duration corresponding to the N time units is the duration of PDCCH blanking, and may be pre-configured by an upper layer and indicated by second indication information, for example, 4 types of duration are configured by the upper layer, and the second indication information indicates one of the durations; or configuring a duration by the higher layer, and triggering the duration by the second indication information, namely the second indication information indicates the skiping, and the skiping duration is the duration configured by the higher layer.
Taking PDCCH monitoring configuration as PDCCH monitoring period as an example, referring to fig. 3 and fig. 4, two SS set switching diagrams in the embodiment of the present invention are respectively given. In fig. 3 and 4, the ue initially monitors the PDCCH with the configuration of SS set 0. In fig. 3, the PDCCH monitoring period configured by SS set0 is a larger period (2 slots), and the PDCCH monitoring period configured by SS set1 is a shorter period (1 slot). In fig. 4, the PDCCH monitoring period configured by SS set0 is a short period (1 slot), and the PDCCH monitoring period configured by SS set1 is a larger period (2 slots).
First indication information indicating monitoring configuration switching is received in a time slot N, second indication information indicating PDCCH skiping is received in the time slot N, and the time length corresponding to N time units is 5 time slots. After 5 slots, switch to SS set 1. If there is a timer corresponding to SS set1 and the timer configured by the higher layer is m slots (or milliseconds, or subframes, where time unit is not limited), the terminal monitors the PDCCH for m slots according to SS set 1.
In a specific implementation, if it is determined that the first indication information and the second indication information are received, the PDCCH monitoring configuration may also be switched first, the PDCCH is monitored according to the switched monitoring configuration (e.g., a switched PDCCH monitoring period), and the duration length of the switched PDCCH monitoring configuration is adjusted according to the duration of the PDCCH skiping, for example, the duration length of the switched PDCCH monitoring period is adjusted according to the duration of the PDCCH skiping.
In the embodiment of the present invention, after the PDCCH monitoring configuration is switched, the time length of the switched PDCCH monitoring configuration is adjusted to: the difference between the initial time length of the switched PDCCH monitoring configuration and the duration of PDCCH skiping.
For example, the SS set0 is switched to the SS set1, and the initial time length corresponding to the SS set1 is the timing duration of a timer configured in advance by an upper layer. Assuming that the timing duration corresponding to the SS set1 preconfigured in the upper layer is Timer and the duration of PDCCH blanking is duration, the time length of the PDCCH monitoring configuration after switching is: timer-duration.
If the time duration of the Timer is 10 time slots and the skiping is 5 time slots, the duration of monitoring the PDCCH according to the configuration of SS set1 is 5 time slots, and the state of monitoring the PDCCH according to the configuration of SS set0 is returned after 5 time slots.
Taking PDCCH monitoring configuration as PDCCH monitoring period as an example, referring to fig. 5 and fig. 6, schematic diagrams of two SS set handovers in the embodiment of the present invention are given. In fig. 5 and 6, the ue initially monitors the PDCCH in the configuration of SS set 0. In fig. 5, the PDCCH monitoring period configured by SS set0 is a larger period (2 slots), and the PDCCH monitoring period configured by SS set1 is a shorter period (1 slot). In fig. 6, the PDCCH monitoring period configured by SS set0 is a short period (1 slot), and the PDCCH monitoring period configured by SS set1 is a larger period (2 slots).
As is apparent from fig. 5 and 6, the timing length corresponding to SS set1 is adjusted to the Timer-duration. In other words, the sum of the timing duration corresponding to the adjusted SS set1 and the duration of PDCCH skiping is equal to the timing duration corresponding to the SS set1 configured in the upper layer before adjustment.
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, whether to switch the PDCCH monitoring configuration may be determined according to the duration of the PDCCH skiping.
In the embodiment of the present invention, if the duration of the PDCCH skiping 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 the PDCCH blanking is equal to 0, that is, N indicated by the second indication information is equal to 0, the PDCCH monitoring configuration is switched.
Referring to fig. 7 and fig. 8, two more SS set switching diagrams in the embodiment of the present invention are shown, respectively.
In fig. 7, the user equipment initially monitors the PDCCH in the configuration of SS set 0. And receiving the first indication information and the second indication information in the time slot n, wherein the first indication information indicates/triggers the switching of the monitoring configuration, and the second indication information indicates that the duration of the PDCCH clipping is more than 0, the switching of the SS set is not carried out, and the PDCCH is monitored by adopting the configuration of the SS set0 after the time slot n.
In fig. 8, the user equipment initially monitors the PDCCH in the configuration of SS set 0. And receiving first indication information and second indication information in a time slot n, wherein the first indication information indicates/triggers the switching of the monitoring configuration, and the second indication information indicates that the duration of PDCCH clipping is equal to 0, then switching the SS set to SS set 1. And switching from SS set1 to SS set0 after the timing duration of the timer reaches a preset duration.
The unit of the PDCCH blanking duration is not limited to a slot, and may be a second, a subframe, a frame, a millisecond, a microsecond, a mini-slot, a symbol, or the like.
In summary, the method for reducing PDCCH monitoring provided by the embodiments of the present invention can enable the UE to skip the handover and PDCCH that receive the handover PDCCH monitoring configuration at the same time, so as to avoid the waste of the overhead of the base station, and avoid the scheduling error and the overhead waste of the base station.
