The following describes in detail a control channel detection method provided in the embodiments of the present application with reference to the accompanying drawings.

The 5G NR system supports configuring one or more CCs or cells for a UE. When the UE is configured in a single carrier mode or a self-scheduling mode in CA, each CC or cell may configure a plurality of control resource sets (CORESET) and a plurality of Search Spaces (SS), including a Common Search Space (CSS) and a UE-specific search space (USS). The network can flexibly configure the number of blind tests for each search space set, and the CORESET and the search space sets can be flexibly associated. The UE blindly detects a Physical Downlink Control Channel (PDCCH) by using various Radio Network Temporary Identities (RNTIs) according to the configured CORESET and SS, demodulates Downlink Control Information (DCI), and acquires scheduling Information of each cell. Each DCI schedules data of one cell.

If the channel quality of some cells is not good enough or the channel blocking probability is high, the network may configure cross-carrier scheduling for the UE, that is, configure the control channel in other cells (e.g., primary cell, PCell) with good channel quality, to cross-carrier schedule data of other cells (e.g., secondary cell, SCell). The subcarrier bandwidths (SCS) of the scheduling cell (scheduled cell) and the scheduled cell (scheduled cell) may be the same or different. The scheduling cell may be in self-scheduling mode, where the cell only schedules itself. The scheduling cell may also schedule one or more other scheduled cells than itself if it is configured with cross-carrier scheduling. The scheduled cell has no PDCCH of its own, and can be scheduled by only one scheduling cell. In the existing NR system, one cell can only be scheduled by one scheduling cell (i.e. can only be self-scheduled or scheduled by another cell), and the PCell can only be scheduled by the PCell itself.

In order to reduce the implementation complexity of the UE, the NR system specifies the maximum detection capability (or referred to as the maximum number of detections) of the PDCCH of the UE in blind detection of one CC or cell. This capability consists of two parts: the maximum number of PDCCH candidates for blind detection in one slot or span, and the maximum number of Channel estimates, i.e., the number of non-overlapping Control Channel Elements (CCEs), required for the UE to perform blind detection. The maximum detection capability of the UE is related to the SCS of the blind detected CC or cell, i.e. the processing capability in the next slot of the different SCS is different (see tables 1-3). In addition, the UE may also report the maximum blind detection capability Y supported by the UE during CA.

Furthermore, to reduce the implementation complexity of the UE, the NR system specifies the DCI size bucket of the UE, i.e. specifies that for each scheduled cell, the maximum number of DCI formats of different sizes that the UE listens to is 4, and the maximum number of DCI formats of different sizes in the USS is 3.

When a plurality of SS sets are configured, since monitoring spaces of different SS sets are independently configured, the number of PDCCH candidates/CCEs may vary at different times. Therefore, the Base Station (BS) is allowed to configure the total number of PDCCH candidates/CCEs per slot to exceed the user capability, which is called Overbooking (Overbooking), and may also be understood as the resource allocation order or mapping order of the SS.

According to the configuration, on each slot, SS sets are mapped according to the following rules:

(1) Preferentially mapping CSS set (i.e. preferentially allocating blind detection resources);

(2) Mapping USS (allocating blind detection resources for USS), mapping (allocating) according to SS set ID ascending order, and if PDCCH candidates/CCEs exceed the limit of user processing capability, then not mapping (allocating) SS sets.

Without the overbooking function, the configuration of the SS set is limited by worst case (i.e. it is required to ensure that the total number of PDCCH candidates/CCEs mapped by the SS set on each slot does not exceed the user capability), so that the BS cannot exert the user blind detection capability to the maximum extent, and multi-user blocking is caused.

For example, as shown in fig. 2, for example, by mapping CCEs to CSS, USS #1, and USS #2, the monitoring times for CSS, USS #1, and USS #2 are arranged such that

slots

1, 5, and 9 cannot be mapped with further CSS and USS #2 (beyond the user capability).

If a UE is configured with multiple carriers for CA and is indicated to have search space sharing capability (e.g., indicated by the parameter earch space sharingca-UL or earch space sharingca-DL), and transmits a serving cell n and a PDCCH candidate with a CCE aggregation level L in the CORESET p _CI,1 Associated DCI format 0 \, or DCI format1 \, 1 (the size of the DCI format is denoted as the first size), if the PDCCH candidate is assumed to be used for transmitting one and the serving cell n _CI,2 If the first and second sizes are equal to each other, the PDCCH candidate can be used to transmit one and the serving cell n _CI,1 Related DCI format 0_1or one DCI format1_1 (i.e., one configured for transmitting scheduling cell n) _CI,2 The PDCCH candidate of DCI (Downlink control information) can also be used for transmitting the scheduling cell n _CI,1 Because the first size and the second size are the same, the method does not increase the complexity of blind detection of users, and simultaneously improves the scheduling flexibility).

Related art proposes a multi-TRP/multi-panel (multi-TRP/multi-panel) scenario, where Transmission of a multi-TRP Transmission can increase reliability and throughput performance of Transmission, for example, a UE can receive the same data or different data from multiple TRPs. The multiple TRP transmission scenarios include:

1) As shown in fig. 3, multi-antenna panel transmission within the same TRP, wherein intra-TRP multi-beams are TRP inner multi-beams;

2) As shown in fig. 4, multiple TRP/panel transmission between multiple TRPs, ideal backhaul;

3) As shown in fig. 5, multiple TRP/panel transmission between multiple TRPs, a non-ideal backhaul.

One scheduling cell may have multiple TRPs, different TRPs may be used to schedule the same or different cells, and one scheduled cell may be scheduled by one or more TPRs.

For a UE, if the UE can support a first set of cells (denoted as

) And a second group of cells (denoted as

) In the first group of cells, either all CORESET on all downlink bandwidth parts (DL BWPs) of each scheduling cell are not configured with coresetpoolndex, or coresetpoolndex of all CORESET on all DL BWPs of each scheduling cell are configured as 0; in the second group of cells, on all DL BWPs of each scheduling cell, the first CORESET is not configured with coresetPoolIndex or is configured with coresetPoolIndex to be 0, and the coresetPoolIndex of the second CORESET is configured with coresetPoolIndex to be 1

Wherein, R is a value reported by the UE.

For enhanced control channel coverage considerations, the PCell is typically deployed at a carrier in the low frequency band, as shown in fig. 6. On the other hand, the low-band carrier has insufficient bandwidth and has been deployed in other series (for example, LTE), where Frequency is Frequency, coverage is Coverage, TDD is time division multiplexing, band is bandwidth, FDD is Frequency division multiplexing, UL is uplink, and DL is downlink. At this time, as shown in fig. 7, it is necessary to implement the SCell scheduling to solve the problem of limited PCell control channel capacity and reduce the PDCCH overhead of the control channel, where PDCCH region is a PDCCH region and DATA region is a DATA region.

However, the related NR system does not support the SCell to be used for scheduling the PCell, and monitoring the PDCCHs from two scheduling cells simultaneously may greatly increase the complexity and power consumption of demodulation and implementation of the UE, increase the hardware finished product of the UE, and is not beneficial to the implementation of the UE.

An embodiment of the present application provides a control channel detection method, as shown in fig. 8, the method includes:

step 101: a terminal acquires a control resource group and/or a cell group; the terminal is configured with a first cell and a second cell, the cell group comprises a first cell, and the first cell is scheduled by at least two cells; in this embodiment, the terminal may obtain the control resource group and/or the cell group configured by the network side device, may also obtain the control resource group and/or the cell group specified by the protocol, may also obtain the control resource group and/or the cell group preconfigured, and may also determine the control resource group and/or the cell group by itself, for example, determine the control resource group and/or the cell group according to the preset rule.

Step 102: and the terminal detects the control channel based on the control resource group and/or the cell group.

In some embodiments, the terminal determines the number of control resources or the budget or the maximum processing capacity of the control resources corresponding to at least one of the control resource groups, and/or the number of control resources or the budget or the maximum processing capacity of the control resources corresponding to at least one of the cell groups;

the control resource is a control resource which needs to be detected by the terminal.

In this embodiment, cell-1 (the first Cell) may be scheduled by control resources on not less than two cells, for example, cell-1 may be a Pcell (primary Cell) or a PScell (primary secondary Cell), and not less than two cells that may schedule Cell-1 may include Cell-1 or may not include Cell-1.Cell-2 (second Cell) may be a Scell used to schedule the Pcell or PScell.

The embodiment can also be used in a scenario of multiple Transmission and Reception Panel (M-TRP), that is, the cell-1 and the cell-2 in the invention can also be TRP-1 and TRP-2 of the same cell, and the ue monitors the PDCCH of SS corresponding to different TRPs (i.e. configured with different CORESET pool indexes).

In some embodiments, the at least two cells comprise the second cell.

In this embodiment, the UE is configured with at least cell-1 and cell-2, where cell-1 may perform self-scheduling, and cell-2 may also schedule cell-1. The UE listens to an SS (hereinafter referred to as SE-SS) for self-scheduling of cell-1 and an SS (hereinafter referred to as CR-SS) for scheduling cell-1 on cell-2 to acquire a scheduling instruction (e.g., DCI) for scheduling cell-1.

Meanwhile, the UE may also monitor other SSs (hereinafter referred to as O-SS) in the cell-2 to obtain scheduling DCI for scheduling the cell-2 and/or other cells (such as the cell-3) in the cell-2.

Wherein the SE-SS, CR-SS or O-SS may be CSS or USS.

A special scenario is that there is no self-scheduling on the cell-1, and a DCI-J is configured on the cell-2 to simultaneously or jointly schedule data of the cell-1 and the cell-2, and at this time, the DCI-2 can also be configured on the cell-2 to independently schedule the cell-1.

In a preferred embodiment, the first cell is a primary cell or a primary and secondary cell, and the second cell is a secondary cell. That is, cell-1 is Pcell or PScell, and cell-2 is a Scell of scheduling cell-1.

In some embodiments, the starting time and/or the ending time of the physical channel is a physical time and/or an absolute time.

Optionally, when comparing the start time or the end time of two physical channels, a comparison based on the start time or the end time of the physical time and/or the absolute time is used. For example, for any two HARQ process IDs in a given scheduled cell, if the UE receives a PDCCH ending at symbol i and the PDCCH schedules the first PDSCH starting at symbol j, the UE does not expect to be scheduled by a PDCCH ending at a time later than symbol i to receive a PDSCH starting at a time earlier than the end time of the first PDSCH. In this comparison, the start time and the end time referred to are the start time and the end time determined using physical time and/or absolute time.

Optionally, the physical time and/or the absolute time is a time determined based on a preset timing. In one embodiment, the predetermined timing is a downlink timing or an uplink timing. More specifically, in an embodiment, the preset timing is a downlink timing or an uplink timing of a certain cell or carrier, for example, a downlink timing or an uplink timing of a cell with a maximum or minimum SCS, or for example, a downlink timing or an uplink timing of a first cell, a Pcell, or a PScell, or for example, a downlink timing or an uplink timing of a Scell that can schedule the Pcell or the PScell, or for example, a downlink timing or an uplink timing of a second cell. In an embodiment, the preset timing is a downlink timing or an uplink timing of a cell in which the physical channel is located. Preferably, the preset timing is a downlink timing.

In some embodiments, the control resources include at least one of:

scheduling, by the second cell, control resources of the first cell;

a control resource for the second cell to self-schedule;

a control resource for the first cell to self-schedule;

the second cell is used to schedule control resources of a third cell, which may be a cell other than the first cell and the second cell;

control resources of a fourth cell, the fourth cell being a cell other than the first cell and the second cell.

In some embodiments, the terminal determines the joint channel monitoring budget for the first cell and the second cell, where the joint channel monitoring budget for the first cell and the second cell may be a weighted sum of a number of control resources corresponding to control resources self-scheduled by the first cell and a number of control resources corresponding to control resources scheduled by the second cell for the first cell, and further, if there are multiple weighted sums, the joint channel monitoring budget for the first cell and the second cell may be a maximum value or a minimum value or a weighted value of the weighted sums.

For example, the joint channel monitoring budget corresponding to the first cell and the second cell is the sum of the maximum number of control resources in the CSS of the first cell and the maximum number of control resources used for scheduling the first cell on the second cell, or is the maximum value of the sum of the maximum number of control resources in the CSS of the first cell and the number of control resources used for scheduling the first cell on the second cell in one slot or span.

In some embodiments, the set of control resources comprises a first set of control resources having a number of control resources P _ control and a second set of control resources having a number of control resources Q _ control;

the first control resource group comprises control resources used by the second cell for scheduling the first cell; the second control resource group comprises control resources used by the second cell for scheduling other cells except the first cell; or

The first control resource group comprises control resources of the first cell which are scheduled by the second cell in a cross-carrier mode; the second control resource group comprises control resources of the second cell self-scheduling and/or the first cell self-scheduling; or

The first control resource group comprises control resources corresponding to scheduled cells scheduled by at least two cells; the second control resource group comprises control resources corresponding to scheduled cells which are scheduled by only one cell.

In some embodiments, if the first control resource group includes the control resources used by the second cell for scheduling the first cell; and the second control resource group comprises control resources used by the second cell for scheduling other cells except the first cell, and the second control resource group comprises control resources of a fifth cell except the first cell and the second cell.

In this embodiment, the UE determines a budget that may need blind detection or detection of the control resource in a specific or arbitrary or each time unit, including upper and lower limits of the number of the control resources.

Optionally, the control resources include a first control resource group and/or a second control resource group, and the first control resource group and/or the second control resource group include control resources of at least one of cell-2 scheduling cell-1, cell-2 self-scheduling, cell-1 self-scheduling, cell-2 scheduling cell-3, and the like.

The second control resource group at least comprises control resources for cell-2 scheduling non-cell-1 (such as cell-2 and/or cell-3), the number of the control resources is Q _ control and is represented as

Optionally, the second control resource group may also include control resources of cells other than cell-1 and cell-2.

In addition, the control resource can also be divided into three parts, namely a control resource of cell-2 scheduling cell-1, a control resource of cell-2 self-scheduling, a control resource of cell-2 scheduling non-cell-1 and non-cell-2 other cells, similarly, a control resource of cell-2 self-scheduling, a control resource of cell-2 scheduling non-cell-1 and non-cell-2 other cells also have corresponding control resource numbers Q _ control1, Q _ control2 and/or corresponding cell numbers Q1, Q2.

In addition, the control resource can be also divided into three parts, namely a control resource of cell-2 scheduling cell-1, a control resource of cell-2 self-scheduling and a control resource of cell-1 self-scheduling.

In another specific example, the first control resource group includes control resources corresponding to cell-2 cross-carrier scheduling cell-1, and the number of the control resources is P _ control, which is expressed as

Preferably, the second control resource group may only contain control resources corresponding to the self-scheduling of cell-2.

Optionally, the second control resource group may also contain control resources of other cells besides cell-1 and cell-2, and these control resources may be used for self-scheduling and cross-carrier scheduling

In another specific example, the first control resource group includes control resources corresponding to scheduled cells scheduled by at least two cells, or control resources corresponding to scheduled cells having more than 1 scheduling cell, and the number of the control resources is P _ control and is denoted as P _ control

The second control resource group includes control resources corresponding to cells scheduled by only one cell, orIn other words, the number of control resources corresponding to the scheduled cell of only one scheduling cell is represented by Q _ control

As an example, the scheduling cell is cell-2, that is, the scheduled cell is scheduled only by cell2

In some embodiments, the cells configured by the terminal are divided into at least a first cell group and a second cell group, where the number of cells associated with the first cell group is P, the number of cells associated with the second cell group is Q, which may be the number of cells in the first cell group is P or the number of scheduled cells in the first cell group is P, which may be the number of cells in the second cell group is Q or the number of scheduled cells in the second cell group is Q;
