Fig. 2 shows a schematic block diagram of a method 200 of transmitting information according to an embodiment of the present application. As shown in fig. 2, the method 200 includes some or all of the following:

s210, the terminal device detects the DCI in the first search space or the search space corresponding to the first control resource set CORESET by adopting the aggregation level in the appointed aggregation level, or based on the DCI format in the appointed DCI format, or in the appointed search space type.

In NR, multiple Transmission points (TRPs)/antenna panels (panels) may independently schedule uplink or downlink data of a terminal device. Data transmission between different TRPs/panels and terminal devices is typically scheduled by an independently configured CORESET or Physical Downlink Control Channel (PDCCH) in the search space, i.e. different CORESET or search space may correspond to different TRPs/panels. The terminal device needs to blind-detect DCI possibly transmitted by the network side in the configured multiple CORESET or search spaces, so as to obtain the scheduling information. The network side may configure a plurality of search spaces or a plurality of CORESET corresponding to the plurality of TRPs/panels for the terminal device, where the first search space may be one or more search spaces in the configured plurality of search spaces, the first CORESET may be one or more CORESET in the configured plurality of CORESET, and the search space corresponding to the first CORESET may also be one or more search spaces in all the search spaces corresponding to the configured plurality of CORESET. Specifically, the first search space may be a partial search space of the configured plurality of search spaces, and the first CORESET may be a partial CORESET of the configured plurality of CORESETs.

The network device may configure a plurality of search spaces or a plurality of CORESET to the terminal device through a physical layer or higher layer signaling, for example, the network device may send configuration information to the terminal device through a Radio Resource Control (RRC) signaling. The first search space or the first CORESET in the embodiment of the present application may be configured by the network device to the terminal device in advance, or may be predefined by the network device and the terminal device (for example, specified in a protocol). For example, the first search space may be at least one auxiliary search space specifically configured by the network device, and the first CORESET may be at least one auxiliary CORESET specifically configured by the network device. For another example, the first search space may be the core set other than the first core set among the plurality of core sets configured by the network device for scheduling data transmission.

The agreed aggregation level, the agreed DCI format and the agreed search space type may be agreed in advance by the terminal device and the network device, and may be, for example, a protocol agreement, and stored in the terminal device and the network device. Or may be indicated to the terminal device by the network device, for example, the network device may indicate the agreed aggregation level, the agreed DCI format, and the agreed search space type to the terminal device through DCI. It should be understood that for all three of the agreed aggregation level, the agreed DCI format and the agreed search space type, some agreed upon by the protocol and others indicated by the network device may be used.

The agreed aggregation level may comprise one or more aggregation levels. The terminal device detects the DCI by using an aggregation level in the agreed aggregation levels, which may be by using some or all of the agreed aggregation levels. For example, the agreed aggregation levels include 4, 8, and 16, and the terminal device may perform DCI detection using the aggregation levels 4 and 8, or may perform DCI detection directly according to the aggregation levels 4, 8, and 16.

Likewise, the agreed DCI format may include one or more DCI formats, and the terminal device performs DCI detection based on the DCI format in the agreed DCI format, which may be based on part or all of the DCI formats in the agreed DCI format. For example, the agreed DCI formats include 0_0, 0_1, 1_0, and 1_1, and the terminal device may use DCI formats 0_1 and 1_1 to perform DCI detection, or may directly perform DCI detection according to DCI formats 0_0, 0_1, 1_0, and 1_ 1.

The agreed search space type may include a common search space or a UE-specific search space.

If the number of the agreed aggregation levels used for DCI detection is smaller than the number of aggregation levels included in the configured aggregation levels, or the number of the agreed DCI formats used for DCI detection is smaller than the number of DCI formats included in the configured DCI formats, or the first search space or all search spaces corresponding to the first CORESET include both a search space configured as an agreed search space type and a search space configured as another search space type, the method in the embodiment of the present application can reduce the number of blind tests of the terminal device, thereby achieving the effects of reducing the complexity of blind tests and reducing the power consumption and processing time of the terminal device.

It should be understood that the aggregation level and DCI format may be regarded as parameters used for DCI detection, and the method of the embodiment of the present application is also applicable to other parameters used for DCI detection. In addition, the search space type may be divided into a common search space and a UE-specific search space, and the method of the embodiment of the present application is also applicable to search space types of other division modes, which should not be limited in the embodiment of the present application.

Optionally, in this embodiment of the application, the terminal device may determine the aggregation level used for DCI detection according to the aggregation level configured for the search space corresponding to the first search space or the first CORESET and the agreed aggregation level, or determine the DCI format used for DCI detection according to the DCI format configured for the search space corresponding to the first search space or the first CORESET and the agreed DCI format, or determine the search space to be DCI detected according to the search space type configured for the search space corresponding to the first search space or the first CORESET and the agreed search space type. And the terminal device can detect the DCI according to the selected aggregation level, the selected DCI format or the selected search space. Alternatively, the selected aggregation level, the selected DCI format, and the selected search space may be combined arbitrarily. For example, the terminal device may perform DCI detection in a first search space or a search space corresponding to a first CORESET by using the selected aggregation level and the selected DCI format. For another example, the terminal device may perform DCI detection in the selected search space by using the selected aggregation level and/or the selected DCI format.

Optionally, the terminal device may perform DCI detection by using an agreed aggregation level in all aggregation levels configured for the first search space or the search space corresponding to the first CORESET. For example, N aggregation levels are configured for the first search space or the search space corresponding to the first CORESET, where M aggregation levels are included in the agreed aggregation levels, and the terminal device only needs to perform DCI detection according to the M aggregation levels, and does not need to perform DCI detection according to other N-M aggregation levels in the N aggregation levels. The terminal device may also perform DCI detection using the aggregation level configured for the first search space or the search space corresponding to the first CORESET in all the agreed aggregation levels. The aggregation level configured for the first search space or the search space corresponding to the first CORESET may completely or partially coincide with the agreed aggregation level. Partial coincidence may be where the agreed-upon aggregation level is a proper subset of the configured aggregation level, or the configured aggregation level may be a proper subset of the agreed-upon aggregation level, or it may also be where the agreed-upon aggregation level intersects the configured aggregation level, but includes other aggregation levels, respectively. For example, configured aggregation levels include aggregation levels 2,4, 8, and 16, while agreed-upon aggregation levels include aggregation levels 8 and 16. As another example, the agreed aggregation levels include aggregation levels 2,4, 8, and 16, and the configured aggregation levels include aggregation levels 8 and 16. As another example, the agreed aggregation levels include aggregation levels 2, 8, and 16, and the configured aggregation levels include aggregation levels 4, 8, and 16.

Optionally, the terminal device also does not expect that the aggregation level configured by the network device for the first search space or the search space corresponding to the first CORESET includes an aggregation level other than the agreed aggregation level. In other words, the terminal device expects that the aggregation level configured by the network device for the first search space or the search space corresponding to the first CORESET includes only the aggregation level in the agreed aggregation levels, and does not include the aggregation levels other than the agreed aggregation level. Then, the aggregation level configured by the network device for the first search space or the search space corresponding to the first CORESET may include only the agreed aggregation level. If the terminal device receives that the aggregation level configured for the first search space or the search space corresponding to the first CORESET includes an aggregation level other than the agreed aggregation level, the terminal device may consider that the configuration is an incorrect configuration, and may not perform DCI detection in the first search space or the search space corresponding to the first CORESET. At this time, if the first CORESET corresponds to a plurality of search spaces, and only some aggregation levels configured in the search spaces include aggregation levels other than the agreed aggregation level, the terminal device may not perform DCI detection only in the search spaces including aggregation levels other than the agreed aggregation level, or may not perform DCI detection in all the search spaces corresponding to the first CORESET.

Optionally, the terminal device may perform DCI detection by using an agreed DCI format among all DCI formats configured for the first search space or the search space corresponding to the first CORESET. For example, N DCI formats are configured for the first search space or the search space corresponding to the first CORESET, where M DCI formats are included in the agreed DCI formats, at this time, the terminal device may perform DCI detection based on only the M DCI formats, and does not need to perform DCI detection based on other N-M DCI formats in the N DCI formats. The terminal device may also perform DCI detection in all the agreed DCI formats by using the DCI format configured for the first search space or the search space corresponding to the first CORESET. The DCI format configured for the first search space or the search space corresponding to the first CORESET may completely or partially overlap with the agreed DCI format. The partial coincidence may be that the agreed DCI format is a proper subset of the configured DCI format, or the configured DCI format may be a proper subset of the agreed DCI format, or may also be that the agreed DCI format and the configured DCI format intersect, but include other DCI formats respectively. For example, the configured DCI formats include DCI formats 0_0, 0_1, 1_0, and 1_1, and the agreed DCI formats include DCI formats 0_1 and 1_ 1. For another example, the agreed DCI formats include DCI formats 0_0, 0_1, 1_0, and 1_1, and the configured DCI formats include DCI formats 0_1 and 1_ 1. For another example, the agreed DCI formats include DCI formats 0_0, 0_1, and 1_1, and the configured DCI formats include DCI formats 0_1, 1_0, and 1_ 1.

Typically, the agreed DCI format may be DCI format 0_1 and/or DCI format 1_ 1. Because the two DCI formats are the most frequently used DCI formats for scheduling data transmission, the terminal only detects the two DCI formats in a part of search spaces, and detects the DCI formats for other purposes in other search spaces, thereby reducing the blind detection times to the maximum extent under the condition of ensuring data transmission scheduling.

Optionally, the terminal device also does not expect that the DCI formats configured for the first search space or the search space corresponding to the first CORESET by the network device include DCI formats other than the agreed DCI format. In other words, the terminal device expects that the DCI format configured for the first search space or the search space corresponding to the first CORESET by the network device includes only the DCI format in the agreed DCI formats, and does not include the DCI format other than the agreed DCI format. Then, the DCI format configured by the network device for the first search space or the search space corresponding to the first CORESET may include only the agreed DCI format. If the terminal device receives that the DCI format configured for the first search space or the search space corresponding to the first CORESET includes a DCI format other than the agreed DCI format, the terminal device may consider that the DCI format is configured incorrectly, and thus, DCI detection is not performed in the first search space or the search space corresponding to the first CORESET. At this time, if the first CORESET corresponds to a plurality of search spaces, and only a part of aggregation levels configured in the search spaces includes DCI formats other than the agreed DCI format, the terminal device may not perform DCI detection only in the search spaces including DCI formats other than the agreed DCI format, or may not perform DCI detection in all the search spaces corresponding to the first CORESET.

Optionally, the terminal device may perform DCI detection only in a search space configured as an agreed search space type in the first search space or the search space corresponding to the first CORESET. For example, the terminal device may perform DCI detection only in the first search space or a common search space in the search space corresponding to the first CORESET, and does not need to perform DCI detection in the UE-specific search space therein. For another example, the terminal device may perform DCI detection only in the first search space or the UE-specific search space in the search space corresponding to the first CORESET, and does not need to perform DCI detection in the common search space.

Optionally, the terminal device also does not expect that the search space type configured for the first search space or the search space corresponding to the first CORESET by the network device includes a search space type other than the agreed search space type. In other words, the terminal device expects that the search space type configured by the network device for the first search space or the search space corresponding to the first CORESET only includes the search space type in the agreed search space types, and does not include the search space types other than the agreed search space type. Then, the search space type configured by the network device for the first search space or the search space corresponding to the first CORESET may only include the agreed search space type. If the terminal device receives that the search space type configured for the first search space or the search space corresponding to the first CORESET includes a search space type other than the agreed search space type, the terminal device may consider that the search space type is an incorrect configuration, and may not perform DCI detection in the first search space or the search space corresponding to the first CORESET. For example, the terminal device does not expect that the first search space or the search space corresponding to the first CORESET is configured as the common search space, and if any of the search spaces is configured as the common search space, the terminal device may not perform DCI detection in the search space. For another example, the terminal device does not expect that the first search space or the search space corresponding to the first CORESET is configured as the UE-specific search space, and if any of the search spaces is configured as the UE-specific search space, the terminal device may not perform DCI detection in the search space. At this time, if the first CORESET corresponds to a plurality of search spaces, and only a part of the search spaces are configured as search space types other than the agreed search space type, the terminal device may not perform DCI detection only on the search space types other than the agreed search space types, or may not perform DCI detection in all the search spaces corresponding to the first CORESET.

Optionally, in this embodiment of the present application, a plurality of search spaces or a plurality of CORESET configured by the network device for the terminal device may all be used for scheduling data transmission, or may be partially used for scheduling data transmission. The multiple search spaces or multiple CORESET may not be used to schedule the transmission of the following information: beam recovery Information (i.e., not a recovery Search Space), parameters of the common Search Space 0, a System Information Block (SIB) 1, other System Information, Paging (Paging) Information, random access Information, and the like.

Optionally, in this embodiment of the present application, the first search space or the first CORESET may be used only for scheduling data transmission.

Optionally, the plurality of search spaces or the plurality of CORESET may correspond to different Transmission Configuration Indications (TCIs), that is, configured with different TCIs, that is, the plurality of search spaces or the plurality of CORESET transmit or receive using different beams. At this time, different ones of the plurality of search spaces or different ones of the plurality of CORESET may be respectively used for different TRPs or different panels to perform data scheduling, so as to support simultaneous downlink transmission of a plurality of TRPs or a plurality of panels.

The technical scheme of the present application is described in detail below with reference to examples 1 to 6.

Example 1: the terminal device and the network device may agree to use only aggregation levels 8 and 16 for DCI transmission in the secondary CORESET. The terminal device may receive the configuration of two CORESET through RRC signaling, wherein the second CORESET is an auxiliary CORESET. The first CORESET associates with search space 1, and the auxiliary CORESET associates with 2 search spaces: search space 2 and search space 3. In the search spaces 1 and 2,4 aggregation levels are configured: 2/4/8/16. In the search space 3, 3 aggregation levels are configured: 4/8/16. The terminal devices respectively use the aggregation level 2/4/8/16 for DCI detection in search space 1. The terminal equipment only adopts the agreed aggregation levels 8 and 16 to perform DCI detection in the search space 2 and the search space 3, and does not adopt the configured aggregation level 2 or 4 to perform DCI detection.

Example 2: the terminal device and the network device may agree that only the configured aggregation level 16 is desired to be configured for DCI transmission in the secondary search space. The terminal device may receive the configuration of two search spaces through RRC signaling, where the second search space is an auxiliary search space. In the search space 1,5 aggregation levels are configured: 1/2/4/8/16. In the search space 2, 3 aggregation levels are configured: 4/8/16. The terminal devices respectively use the aggregation level 1/2/4/8/16 for DCI detection in search space 1. Since aggregation levels other than the agreed aggregation level are configured in the search space 2, the terminal device may not perform DCI detection in the search space 2. At this time, if the search space 2 and the search space 3 are associated with the same CORESET, the terminal device may not perform DCI detection in all the search spaces (including the search space 2 and the search space 3) associated with the CORESET.

Example 3: the terminal device and the network device may agree to use only the UE-specific space for DCI transmission in other CORESET except the first CORESET. The terminal device may receive the configuration of three CORESET through RRC signaling. The first CORESET is related to the search space 1 and the search space 2, the second CORESET is related to the search space 3 and the search space 4, and the third CORESET is related to the search space 5. Where search spaces 1 and 3 are common search spaces and search spaces 2,4,5 are UE-specific search spaces. The terminal device may perform DCI detection in the search space 1 by using the DCI format corresponding to the common search space. In the search spaces 2,4, and 5, DCI detection may be performed using DCI formats corresponding to UE-specific search spaces. Since the search space 3 is not the agreed search space type, the terminal device may not perform DCI detection in the search space.

Example 4: the terminal device and the network device may agree that the terminal does not expect other CORESET associated UE-specific spaces outside the first CORESET. The terminal device may receive the configuration of three CORESET through RRC signaling. The first CORESET is related to the search space 1 and the search space 2, the second CORESET is related to the search space 3 and the search space 4, and the third CORESET is related to the search space 5. Wherein the search spaces 1,3,5 are common search spaces and the search spaces 2,4 are UE-specific search spaces. The terminal may perform DCI detection in the search spaces 1 and 5 using DCI formats corresponding to the common search space. In the search space 2, DCI detection may be performed using a DCI format corresponding to the UE-specific search space. Since search space 4 is not the agreed search space type, the terminal considers this to be an incorrect configuration, and DCI detection may not be performed in all search spaces (including search spaces 3 and 4) associated with the second CORESET associated with the search space.

Example 5: the terminal device and the network device may agree to detect only the DCI format 1_1 in other CORESET than the first CORESET. The terminal device may receive the configuration of the two CORESET through RRC signaling. Wherein, the first CORESET is related to the search space 1 and the search space 2, and the second CORESET is related to the search space 3. Wherein, the search space 1 is a common search space including DCI formats 0_0, 1_0, 2_1, 2_2, and 2_3, and the search spaces 2 and 3 are UE-specific search spaces including DCI formats 0_1, 1_0, 0_1, and 1_ 1. The terminal device can blind-detect DCI formats 0_0, 1_0, 2_1, 2_2, 2_3 in search space 1, respectively. DCI formats 0_1, 1_0, 0_1, 1_1 may be blind-detected in search space 2, respectively. In the search space 3, although the DCI formats 0_1, 1_0, 0_1, and 1_1 are included in the configuration, the terminal device blindly detects only the DCI format 1_1 that is agreed, and does not blindly detect DCI formats of other configurations.

Example 6: the terminal device and the network device may agree that the terminal does not desire to be configured with other DCI formats than DCI formats 0_1 and 1_1 in other CORESET than the first CORESET. The terminal device may receive the configuration of the two CORESET through RRC signaling. Wherein, the first CORESET associates the search space 1 and the search space 2, and the second CORESET associates the search space 3 and the search space 4. Search space 1 is a common search space containing DCI formats 0_0, 1_0, 2_1, 2_2, 2_3, search spaces 2 and 3 are UE-specific search spaces containing DCI formats 0_1, 1_0, 0_1, 1_1, and search space 4 is a UE-specific search space containing DCI formats 0_1 and 1_ 1. The terminal device may blind-detect DCI formats 0_0, 1_0, 2_1, 2_2, and 2_3 in search space 1 and DCI formats 0_1, 1_0, and 1_1 in search space 2, respectively. Since DCI formats 0_0 and 1_0 other than the agreed DCI format are configured in the search space 3, the terminal device considers that this is an erroneous configuration, and may not perform DCI detection in all search spaces (3 and 4) associated with the second core set associated with the search space 3.
