The control channel detection method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

The 5G NR system supports configuring one or more CCs or cells for the UE. When the UE is configured in single carrier mode or self-scheduling mode under CA, each CC or cell can be configured with multiple control resource sets (CORESET) and multiple search spaces (search spaces, SS), including common search spaces (common search space) , CSS) and UE-specific search space (UE-specific search space, USS). The network can flexibly configure the number of blind detections for each search space set, and the CORESET can be flexibly associated with the search space set. According to the configured CORESET and SS, the UE blindly detects the Physical Downlink Control Channel (PDCCH) by using various Radio Network Tempory Identity (RNTI), and demodulates the Downlink Control Information (Downlink Control Information, DCI), Obtain scheduling information for each cell. Each DCI schedules data for one cell.

If the channel quality of some cells is not good enough, or the channel blocking probability is high, the network can configure cross-carrier scheduling for the UE, that is, configure the control channel in other cells with better channel quality (for example, the primary cell, PCell), to Data of other cells (eg, secondary cells, SCells) are scheduled across carriers. The subcarrier spacing (SCS) of a scheduling cell (scheduling cell) and a scheduled cell (scheduled cell) may be the same or different. The scheduling cell may be in self-scheduling mode, in which case the cell only schedules itself. If the scheduling cell is configured with cross-carrier scheduling, it can also schedule one or more scheduled cells other than itself. The scheduled cell does not have its own PDCCH and can only be scheduled by one scheduling cell. In the existing NR system, a cell can only be scheduled by one scheduling cell (that is, it 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) for the UE to blindly detect the PDCCH of a CC or a cell. This capability consists of two parts: the maximum number of PDCCH candidates for blind detection in a slot or span, and the maximum number of channel estimates required by the UE to perform blind detection, that is, non-overlapping control channel elements (Control Channel Elements). , CCE). The maximum detection capability of the UE is related to the blindly detected CC or the SCS of the cell, that is, the processing capability in the next slot of different SCSs is different (see Table 1-3). In addition, the UE can also report the maximum blind detection capability Y it supports when CA is reported.

In addition, in order to reduce the implementation complexity of the UE, the NR system specifies the DCI size budget of the UE, that is, it specifies that for each scheduled cell, the maximum number of DCI formats of different sizes that the UE monitors is 4, and the different sizes in the USS are specified. The maximum number of DCI formats is 3.

When multiple SS sets (search space sets, search space sets) are configured, since the monitoring spaces of different SS sets are configured independently, the number of PDCCH candidates/CCEs will change at different times. Therefore, the base station (BS) is allowed to configure the total number of PDCCH candidates/CCEs on each slot to exceed the user's capacity, which is called overbooking, which can also be understood as the resource allocation order or mapping order of the SS.

According to the configuration, on each slot, the SS set is mapped according to the following rules:

(1) Priority mapping CSS set (ie, priority allocation of blind detection resources);

(2) Mapping USS (allocating blind detection resources for USS), mapping (allocating) in ascending order of SS set ID, if PDCCH candidates/CCEs exceed the limit of user processing capacity, then no longer map (allocate) SS set.

If there is no overbooking function, the configuration of the SS set will be limited by the worst case (worst case) (that is, it is necessary to ensure that the total number of PDCCH candidates/CCEs mapped by the SS set on each slot does not exceed the user's ability), so the maximum number in the BS cannot be exceeded. The user's blind detection ability is maximized, and multi-user blocking is caused.

For example, as shown in Figure 2, taking CSS, USS#1, USS#2 mapping CCE as an example, the monitoring time configuration of CSS, USS#1, USS#2 is as follows. For slots 1, 5, and 9, CSS, USS#1 are mapped After that, no further mapping of USS#2 is possible (exceeds user capability).

If a UE is configured with multiple carriers for CA, and it is indicated that it has search space sharing (search space sharing) capability (eg indicated by the parameter searchSpaceSharingCA-UL or searchSpaceSharingCA-DL), and in CORESET p for a CCE aggregation level Send a DCI format 0_1 or a DCI format 1_1 related to the serving cell n _{CI, 1} for the PDCCH candidate of L (the size of the DCI format is recorded as the first size), if the PDCCH candidate is assumed to be used to send a serving cell. n _{CI, 2} related DCI format 0_1ora DCI format1_1 (record the size of the DCI format as the second size), the first size and the second size are equal, then the PDCCH candidate can be used to send a serving cell n _{CI, 1} The related DCI format 0_1 or a DCI format 1_1 (that is, a PDCCH candidate configured for sending the DCI of the scheduling cell n _{CI, 2} can also be used to send the DCI of the scheduling cell n _{CI, 1} , due to the first size and the second The size is the same, this approach will not increase the complexity of the user's blind detection, and at the same time improve the scheduling flexibility).

In the related art, a multi-transmission and reception point/multi-antenna panel (multi-TRP/multi-panel) scenario is proposed, and multi-transmission and reception point (Transmission and Reception Point, TRP) transmission can increase transmission reliability and throughput performance, such as The UE may receive the same data or different data from multiple TRPs. Multi-TRP transmission scenarios include:

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

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

3) As shown in Figure 5, multi-TRP/panel transmission between multi-TRPs is not an ideal backhaul line.

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

Then the UE determines the number of serving cells as

where R is a value reported by the UE.

For the consideration of enhancing the coverage of the control channel, as shown in Figure 6, the PCell is generally deployed in the carrier of the low frequency band. On the other hand, low-band carriers have insufficient bandwidth and have been deployed to other series (such as LTE), where Frequency is frequency, Coverage is coverage, TDD is time division multiplexing, band is bandwidth, and 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 SCell scheduling of PCell to solve the problem of limited PCell control channel capacity and reduce control channel PDCCH overhead, where the PDCCH region is the PDCCH region and the DATA region is the data region.

However, the related NR system does not support the use of SCell to schedule PCell, and monitoring the PDCCH from two scheduling cells at the same time will greatly increase the complexity and power consumption of UE demodulation and implementation, and increase the hardware finished product of UE, which is not conducive to the implementation of UE. .

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

Step 101: the 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 includes a first cell, and the first cell is scheduled by at least two cells; this implementation In an example, the terminal may obtain the control resource group and/or cell group configured by the network side equipment, may also obtain the control resource group and/or cell group specified in the protocol, and may also obtain the pre-configured control resource group and/or cell group, You can also determine the control resource group and/or the cell group yourself, for example, determine the control resource group and/or the cell group according to a preset rule.

Step 102: The terminal performs control channel detection 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 maximum processing capability of the control resources corresponding to at least one of the control resource groups, and/or the number of control resources or control resources corresponding to at least one of the cell groups. The budget or maximum processing capacity of the resource;

Wherein, the control resources are control resources that the terminal needs to detect.

In this embodiment of the present application, the terminal is configured with at least a first cell and a second cell, the first cell is scheduled by at least two cells, the terminal acquires a control resource group and/or a cell group, and based on the control resource group and/or cell group and/or cell group, perform control channel detection, such as determining the number of control resources corresponding to at least one of the control resource groups or the budget or maximum processing capability of the control resources, and/or, the number of control resources corresponding to at least one of the cell groups number or control the budget or maximum processing power of a resource. The technical solution of this embodiment can reduce the complexity of demodulation and implementation, ensure consistent understanding between the terminal and the device on the network side, and support scheduling of one cell by multiple cells.

In this embodiment, Cell-1 (first cell) can be scheduled by control resources on not less than two cells. For example, cell-1 can be a Pcell (primary cell) or PScell (primary and secondary cell), and cell- No less than two cells of 1 may contain cell-1 or may not contain cell-1. Cell-2 (second cell) may be an Scell for scheduling Pcell or PScell.

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

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

In this embodiment, the UE is configured with at least cell-1 and cell-2, wherein, cell-1 can perform self-scheduling, and cell-2 can also schedule cell-1. The UE monitors the self-scheduled SS of cell-1 (hereinafter referred to as SE-SS) and the SS of cell-2 scheduling cell-1 (hereinafter referred to as CR-SS) to obtain scheduling instructions (such as DCI) for scheduling cell-1 ).

At the same time, the UE may also monitor other SSs (hereinafter referred to as O-SSs) on cell-2 to obtain the scheduling DCIs scheduled on cell-2 and/or other cells (such as cell-3) on cell-2.

Wherein, the above SE-SS, CR-SS or O-SS can all be CSS or USS.

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

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 a Pcell or PScell, and cell-2 is an Scell that schedules cell-1.

In some embodiments, the start time and/or end time of the physical channel adopts physical time and/or absolute time.

Optionally, when comparing the start time or end time of two physical channels, the comparison is based on the start time or end time of physical time and/or absolute time. 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 hit by an end time The PDCCH later than symbol i is scheduled to receive a PDSCH whose start time is earlier than the end time of the first PDSCH. In this comparison, the start time and end time mentioned are the start time and 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 an embodiment, the preset timing is downlink timing or uplink timing. More specifically, in an embodiment, the preset timing is the downlink timing or uplink timing of a certain cell or carrier, such as the downlink timing or uplink timing of the cell with the maximum or minimum SCS, or the first cell or Pcell or PScell, for example. The downlink timing or uplink timing of the second cell, or, for example, the downlink timing or uplink timing of the Scell of the Pcell or PScell, or the downlink timing or uplink timing of the second cell, for example. In an embodiment, the preset timing is the downlink timing or the uplink timing of the cell where the physical channel is located. Preferably, the preset timing is downlink timing.

In some embodiments, the control resource includes at least one of the following:

for the second cell to schedule control resources of the first cell;

self-scheduled control resources of the second cell;

self-scheduled control resources of the first cell;

the second cell is used for scheduling control resources of a third cell, where the third cell may be a cell other than the first cell and the second cell;

Control resources of a fourth cell, where the fourth cell is a cell other than the first cell and the second cell.

Further, if there are multiple weighted sums, the joint channel monitoring budget corresponding to the first cell and the second cell is these The maximum value or the minimum value or the weighted value in the weighted sum. Alternatively, further, the joint channel monitoring budget corresponding to the first cell and the second cell may be the maximum number of resources corresponding to the self-scheduled control resources of the first cell and the second The weighted sum of the maximum number of resources corresponding to the control resources of the first cell scheduled by the cell. Further optionally, the control resources of the first cell self-scheduling and the control resources of the second cell scheduling the first cell are in the same time unit.

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 to schedule the first cell on the second cell, or, a The maximum value among the maximum number of control resources in the CSS of the first cell on the slot or span and the sum of the number of control resources used for scheduling the first cell on the second cell.

The first control resource group includes the cross-carrier scheduling control resources of the first cell by the second cell; the second control resource group includes the second cell self-scheduling and/or the first cell self-scheduling control resources; or

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

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