Description
Technical Field

Background
In a New Radio access (NR) system, a base station may configure one or more control resource sets (Control Resource Set, CORESET) of a User Equipment (UE) on an active Bandwidth (BWP) of a serving cell to detect downlink control signaling (Downlink Control Information, DCI) belonging to the base station according to its Radio network temporary identifier (Radio Network Temporary Identifier, RNTI). For example, for a scenario in which carrier aggregation is not considered, the UE is operating on one carrier, i.e. one serving cell, the base station may configure the UE to detect the search space in one or more CORESET on the active BWP in the carrier, the UE detect DCI belonging to itself according to its RNTI, and then receive data or upload data according to the DCI. One serving cell may configure one or more BWP, which may be active or inactive. The UE need not detect DCI on the inactive BWP.
The UE may configure one serving cell or may configure a plurality of serving cells. For each serving cell, one or more sets of control resources (Control Resource Set, CORESET) may be configured separately per BWP, and one or more sets of search spaces (SEARCH SPACE SET) may be configured on each CORESET. The network may configure the number of times the UE detects DCI, aggregation level, DCI format, etc., and the timing of detecting DCI, etc., in each search space set. The number of times of the UE performing different DCI blind tests is closely related to the power consumption of the UE, so that the search space set (SEARCH SPACE SET groups) of the UE are considered to be switched in a New Radio (NR) system to achieve the purpose of saving electricity.

Detailed Description
As described in the background art, in the prior art, the network needs to instruct the switching of the search space set group each time through signaling, which increases signaling overhead and increases the number of times the UE detects DCI, thereby causing the power consumption of the UE to also increase.
In the technical scheme of the invention, when the user equipment detects DCI, the search space set group can be selected according to the length type of the current DRX period so as to be used for detecting the DCI. According to the technical scheme, the user equipment directly selects the search space set based on the length type of the current DRX period, and does not need to send signaling to instruct by a network, so that the number of times of detecting the signaling can be reduced, the power consumption is reduced, and the purpose of further saving electricity is achieved.
The technical scheme of the invention can be applied to 5G (5 Generation) communication systems, 4G and 3G communication systems, and also can be applied to various new communication systems in the future, such as 6G, 7G and the like.
The technical scheme of the invention is also applicable to different network architectures, including but not limited to a relay network architecture, a dual link architecture, a Vehicle-to-evaluation architecture and the like.
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Fig. 1 is a flowchart of a DCI detection method according to an embodiment of the present invention.
The DCI detection method of the embodiment of the present invention may be used at the user equipment side, that is, the user equipment may perform each step of the method shown in fig. 1.
Specifically, the DCI detection method may include the steps of:
Step S101: determining the length type of the current DRX cycle;
Step S102: and selecting a search space set group corresponding to the current length type from all search space set groups corresponding to the activated BWP according to the length type of the current DRX period in the activated BWP of the serving cell.
The longer the relative length of the DRX period is, the fewer the detection times of the selected search space set group in each time slot are;
Step S103: and detecting DCI in the selected search space set group.
It should be noted that the serial numbers of the steps in the present embodiment do not represent a limitation on the execution sequence of the steps.
In the embodiment of the invention, the UE accesses the serving cell to establish radio resource control (Radio Resource Control, RRC) connection. To save power, the network configures discontinuous reception (Discontinuous Reception, DRX) for the UE and may configure DRX cycles of different lengths.
The network may also configure multiple search space set groups for the UE. If the UE configures multiple serving cells, each serving cell may configure multiple search space set groups, respectively. For each serving cell, one or more BWP may be configured, and each BWP may configure one or more search space set groups. Each set of search space sets may contain one or more search space sets. Different serving cells may employ respective corresponding subcarrier spacings such as 15kHz, 30kHz, 60kHz, or the like. The number of candidate DCIs that can be detected in one slot (i.e., the number of physical downlink control channel (Physical Downlink Control Channel, PDCCH) Blind detections (PDCCH detections, or Blind detections)) is different when the UE applies different subcarriers. Taking a serving cell with 15kHz subcarrier as an example, UE can support maximum 44 DCI detection times in one slot.
For each set of search spaces within the set of sets of search spaces, the network may configure the number of times the UE needs to detect DCI, the DCI format, the timing at which the DCI is detected, and so on. The number of detections in each time slot of the search space set group may be the sum of the number of DCI that the UE needs to detect in each time slot over all the search space sets contained in the search space set group. It should be noted that, other duration units may be used to count the sum of DCI times that the UE needs to detect, for example, the sum of DCI times that the UE needs to detect is counted with 7 OFDM symbol lengths as a Span (Span), and the method described in this patent is also applicable.
Of course, the duration of the span may be any other practicable length of time, which is not limited by the embodiments of the present invention.
Specifically, one DCI is composed of at least one Control channel element (Control CHANNEL ELEMENT, CCE), and the number of CCEs constituting one DCI is referred to as an aggregation level (Aggregation level), which may be 1,2, 4, 8, or 16. One CCE is composed of 6 Resource Element groups (Resource Element Group, REGs), where each REG refers to one Resource Block (RB) occupying one orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol duration, i.e., each REG contains 12 Resource Elements (REs) consecutive in the frequency domain. Considering that demodulation reference signals are included in 12 REs, there are less than 12 REs per REG that are actually effectively used for transmitting DCI. The more times the UE needs to detect DCI in one search space set, the greater the power consumption of the UE, which is unfavorable for power saving of the UE.
In the implementation of step S101, the UE may determine a length type of a current DRX cycle in which the UE is currently located, where the length type of the current DRX cycle indicates a relative length of the current DRX cycle to other DRX cycles in all DRX cycles. Wherein the lengths of all DRX cycles configured by the network for the UE are different.
For example, the network configures the UE with two types of length of DRX cycles, a Long DRX cycle (Long DRX) and a Short DRX cycle (Short DRX), which may also be referred to as a Long DRX cycle and a Short DRX cycle. The cycle length of the DRX long cycle is longer than that of the DRX short cycle. When the UE determines that the length type of the current DRX cycle is a DRX short cycle, the UE may determine that the cycle length of the DRX short cycle is shorter among all DRX cycles configured by the UE.
Specifically, the UE may learn the length type of the current DRX cycle through medium access control (Medium Access Control, MAC) layer signaling, i.e., the network may instruct the UE to enter the DRX long cycle, or the short cycle, through MAC layer control signaling; or the UE acquires the length type of the current DRX period through the DRX short period timer. Wherein the DRX short period timer is used for counting the number of DRX short periods. For example, the UE has entered 5 DRX short cycles, then the UE may determine whether it is currently in a DRX short cycle based on whether the DRX short cycle timer has expired; if the timer does not timeout, the UE determines that the current DRX short period exists; if the timer has timed out or is not running, the UE needs to go into DRX long cycle.
As previously described, each BWP per serving cell may configure a corresponding set of search spaces. In the implementation of step S102, the UE selects a search space set group from all search space set groups corresponding to the activated BWP of the serving cell according to the length type of the current DRX cycle. In order to achieve the purpose of power saving, the longer the relative length of the current DRX cycle and other DRX cycles in all DRX cycles, the fewer the detection times of the selected search space set group in each time slot.
In a specific embodiment, the length type of the DRX cycle is selected from a DRX long cycle and a DRX short cycle, and the number of search space set groups is two. Step S102 shown in fig. 1 may include the steps of: and if the length type of the current DRX cycle is the DRX short cycle, selecting a search space set group with more detection times from the two search space set groups.
In a variation, if the current DRX cycle is the DRX long cycle, a search space set group with a smaller number of detections from the two search space set groups is selected.
In this embodiment, the network configures the UE with two types of length of DRX cycles, DRX Long cycle (Long DRX) and DRX Short cycle (Short DRX). The UE adopts a search space set group with a large number of detections in the Short DRX cycle (i.e., the UE detects DCI on a search space set in the search space set group). And the UE adopts a search space set group with less detection times in the Long DRX period. In other words, the UE determines the DRX cycle according to the MAC layer DRX command, and then decides to use the search space set corresponding to the DRX cycle. The UE may specifically determine the search space set applied during short DRX and Long DRX through DCI detection times corresponding to the search space set, where the DCI detection times may be counted according to a Slot or according to a Span.
It should be noted that, the mechanism of applying short DRX and Long DRX by the UE is the same as the existing manner, and will not be described here again.
In the implementation of step S103, the UE detects DCI using the selected set of search spaces, that is, the UE detects DCI on the set of search spaces corresponding to the set of search spaces.
Compared with the prior art that the network is required to indicate the switching of the search space set group each time through signaling, the embodiment of the invention adopts an implicit mode of switching the search space set group, and the network is not required to send additional signaling for indication, so that the number of times of signaling detection can be reduced, the power consumption is reduced, and the purpose of further saving electricity is realized.
In one non-limiting embodiment of the invention, the number of search space set groups is the same as the number of length types of DRX cycles, the length type of the current DRX cycle being represented by the ordering of the current DRX cycle in terms of cycle length among all DRX cycles. Step S102 shown in fig. 1 may include the steps of: sorting all the search space set groups according to DCI detection times of each search space set group; and selecting a search space set group with the same ordering as the ordering of the current DRX cycle in all DRX cycles.
In a specific implementation, all DRX cycles configured by the UE may be ordered in advance according to a cycle length, e.g. from long to short or from short to long, and each type of DRX cycle has a corresponding sequence number. For example, the UE configures three types (i.e., three lengths) of DRX cycles, which are ordered from short to long, each type of DRX cycle having a corresponding sequence number, e.g., 1, 2, 3. Accordingly, the network configures 3 search space set groups for the UE according to the BWP, when the BWP is in an active state, the UE needs to detect DCI on the search space set group corresponding to the BWP, and when selecting the search space set group, the UE may first rank the search space set group, for example, rank the UE according to the number of times of detection from more to less, and then select the search space set group with the same rank as the current DRX cycle in all DRX cycles.
When all DRX cycles are ordered from short to long, the search space set is ordered in order from more to less; when all DRX cycles are ordered from long to short, then the search space set groups are ordered in order from less to more, in which case the UE can only select the search space set group ordered the same as the current DRX cycle ordered in all DRX cycles.
In a non-limiting embodiment of the present invention, the following steps may be further included before step S101 shown in fig. 1: and receiving the association relation between the length type of the DRX cycle sent by the network side and the search space set group. Accordingly, step S102 shown in fig. 1 may include the following steps: and selecting a corresponding search space set group according to the length type of the current DRX period and the association relation.
In this embodiment, when configuring the search space set, the network may directly indicate whether each search space set is applied to short DRX or long DRX, that is, the network indicates, to the UE, an association relationship between the length type of the DRX cycle and the search space set, so that the UE determines the search space set to be used directly according to the association relationship.
Compared with the embodiment, the method and the device for detecting the search space set group can improve the calculation efficiency of the UE without calculating the detection times of each search space set group.
In one non-limiting embodiment of the present invention, step S102 shown in FIG. 1 may include the steps of: selecting a search space set group with more detection times from the two corresponding search space set groups in an initial preset number of DRX short periods; and if the scheduling is not obtained in the preset number of DRX short periods or after the initial preset number of DRX short periods, selecting a search space set group with fewer detection times from the two corresponding search space set groups no matter whether the UE obtains the scheduling or not.
In this embodiment, the network configures a DRX long period and a DRX short period for the UE, and simultaneously configures two search space set groups for the UE according to BWP. The DRX Short Cycle counter (DRX-ShortCycleTimer) may contain multiple DRX Short cycles (Short DRX cycles), e.g. up to 16 DRX Short cycles. Once the DRX short cycle counter times out, the UE transitions to a DRX long cycle. The UE typically has scheduling requirements in the first few DRX short cycles, the latter ones not being strong. In this case, the UE adopts a search space set group with a larger number of detections in the first several DRX short cycles, and once the UE does not obtain scheduling in the current DRX short cycle (or does not obtain scheduling in consecutive several DRX short cycles) or after the initial preset number of DRX short cycles, it shifts to a search space set group with a smaller number of detections.
In particular implementations, the UE may maintain a timer or counter to keep track of a consecutive preset number of DRX short cycles for which no scheduling is obtained. This preset number may be 1 or other integer value lower than the DRX short cycle number corresponding to DRX-ShortCycleTimer.
The embodiment of the invention can use the search space set group with less detection times when the scheduling requirement of the UE is not strong so as to realize better power saving.
It will be appreciated that, regarding the specific number of preset values, the setting may be performed according to an actual application scenario, which is not limited in this embodiment of the present invention.
Accordingly, in this embodiment, the UE uses the search space set group with a smaller number of detections in the DRX long cycle.
In a variation, the DRX short cycle may correspond to two sets of search space sets (two sets of search space sets differ in DCI detection times in each time slot or Span), for example, one set of search space sets corresponds to 30 DCI blind tests (e.g., 30 DCI blind tests in one time slot), and the other set of search space sets corresponds to 16 DCI blind tests (one time slot). The DRX long cycle may correspond to a set of search space sets.
And particularly, a search space set with more detection times is adopted in the first several DRX short periods of the DRX short period, and once the scheduling is not obtained in the current DRX short period or after the first several DRX short periods, the search space set group with less detection times is shifted to. Taking DRX-ShortCycleTimer as 8 short DRX cycles and the initial preset number of DRX short cycles as 4 as an example, when the UE enters the short DRX cycle, the UE starts DRX-ShortCycleTimer, UE to perform DCI detection in a search space set group with more detection times. If the UE does not receive the scheduling information in the first 4 short DRX cycles after entering the short DRX cycle, the UE performs DCI detection in the search space set group with less detection times in the last 4 short DRX cycles; or the UE directly detects DCI in the search space set group with small detection times in the following 4 short DRX cycles. Once DRX-ShortCycleTimer times out, the UE enters a long DRX cycle, and the UE continues DCI detection in the search space set with a small number of detections.
In one non-limiting embodiment of the present invention, the UE is configured with a DRX Short period (Short DRX) and a DRX Long period (Long DRX), where the UE corresponds to multiple sets of search space sets (different detection times per slot or per span) and the DRX Long period corresponds to one or more sets of search space sets. That is, the base station configures corresponding search space set groups according to the length type of the DRX cycle of the UE, respectively.
The base station configures the number of search space set groups corresponding to the DRX short cycle and an index (index) through RRC signaling, for example, the base station configures the number of search space set groups corresponding to the DRX short cycle to two sets through RRC signaling, the index is 0 and 1, respectively, and the base station may configure the search space set group corresponding to the DRX short cycle according to each BWP of the serving cell. In the DRX short cycle, the base station may instruct the UE to switch the search space set group through DCI. For example, there may be one bit in the DCI dedicated to indicating whether index0 or 1 search space set group is employed. Specifically, the base station decides whether to switch the search space set group according to the scheduling requirement of the UE. For example, the scheduling requirement of the UE becomes strong, and the UE currently uses a search space set group with a smaller detection number, and the base station instructs the UE to switch to the search space set group with a larger detection number.
When the UE configures a plurality of serving cells, the UE detects DCI belonging to itself on a physical downlink control channel on a search space set detected on an active BWP of each serving cell. For the search space set group of DCI indication applications, there may be the following implementation schemes: the UE receives DCI for switching the search space set on any one service cell, and the UE implements the switching of the search space set on all the service cells; the UE receives DCI switching the search space set on one serving cell, and the UE switches the search space set only on that serving cell, i.e. the DCI only controls the switching of the search space set on a single serving cell.
In specific implementation, the UE detects DCI by using a default search space set, and after detecting DCI, obtains whether there is an index of the search space set in the DCI, if so, indicates that the search space set needs to be switched, and switches to the search space set pointed by the index to detect the DCI.
In the DRX long period, if only one set of search space set group corresponding to the DRX long period exists, the UE does not need to have an independent bit to indicate the search space set group in the DCI when in the DRX long period; if the DRX long period corresponds to multiple sets of search space set groups, the UE needs to have independent bits in DCI detected during the DRX long period to indicate the search space set groups to be applied.
In the embodiment of the invention, the network can effectively reduce the bit for indicating the search space set in DCI when indicating to switch the search space set by configuring the search space set corresponding to the length types of different DRX periods, thereby reducing the signaling overhead.
Referring to fig. 2, the embodiment of the invention also discloses a DCI detection device 20. The DCI detection apparatus 20 may include:
A cycle type determining module 201, configured to determine a length type of a current DRX cycle;
A search space set selection module 202, configured to select, in an active BWP of a serving cell, a search space set corresponding to a current length type from all search space sets corresponding to the active BWP according to the length type of the current DRX cycle, where the longer the relative length is, the fewer detection times of the selected search space set in each time slot are;
the DCI detection module 203 is configured to detect DCI in the selected search space set.
In the embodiment of the invention, the user equipment directly selects the search space set based on the length type of the current DRX period, does not need to send signaling to instruct by a network, and can reduce the frequency of detecting the signaling, thereby reducing the power consumption and realizing the purpose of further saving electricity.
