Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a control channel configuration method, detection method, apparatus, device, and mobile terminal. Background Technology

[0002] In a New Radio (NR) system, each terminal can be configured with a maximum of 10 search spaces. The configuration information for each search space can include: period, offset value, length, detected symbols, aggregation level of the Physical Downlink Control Channel (PDCCH) candidate set, number of PDCCH candidate sets, and search space type. The search space type includes public search spaces and terminal-specific search spaces. If the search space type is a public search space, the configuration information also includes the format of the Downlink Control Information (DCI) detected in that search space, such as DCI format 0_0 / 1_0, DCI format 2_x series, etc.

[0003] In multicast / broadcast scenarios in NR, the network side uses a common Radio Network Temporary Identifier (RNTI) (e.g., Group Radio Network Temporary Identifier (G-RNTI)) to CRC-scramble the PDCCH carrying the corresponding Physical Downlink Shared Channel (PDSCH). This means multiple terminals detect and receive the same PDCCH. To ensure that multiple terminals detect the same PDCCH, the search space for multicast and / or broadcast services (i.e., the search space for G-RNTI-scrambled PDCCH) is a common search space. Different PDCCHs scheduling multicast and / or broadcast services are scrambled with different G-RNTI values ​​using different CRC values ​​to distinguish between them.

[0004] Considering that a terminal may receive more than one multicast and / or broadcast service, and that the periods and G-RNTI values ​​of different multicast and / or broadcast services may vary, the current search space configuration method allows a terminal to be configured to detect multiple multicast and / or broadcast services by configuring multiple common search spaces, each with a different detection period and G-RNTI. However, currently, terminals only support a maximum of 10 search spaces, which consumes a large number of search space indexes and compresses other search spaces, such as reducing the number of configurable search spaces for the terminal's dedicated search space, thus reducing the flexibility of unicast data scheduling. Summary of the Invention

[0005] The purpose of this invention is to provide a control channel configuration method, detection method, apparatus, device, and mobile terminal, which solves the problem in the prior art that multicast and / or broadcast services occupy a lot of search space resources, resulting in a reduction in the number of configurable search spaces for the terminal's dedicated search space and a decrease in scheduling flexibility.

[0006] To achieve the above objectives, embodiments of the present invention provide a control channel configuration method, applied to a network-side device, comprising:

[0007] Configure a search space for the terminal. The search space is associated with at least one Radio Network Temporary Identifier (RNTI).

This search space is associated with at least one Radio Network Temporary Identifier (RNTI), and each RNTI corresponds to its own multicast and / or broadcast service.

[0025] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0027] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0028] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0029] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0030] like Figure 1 As shown, an embodiment of the present invention provides a control channel configuration method applied to a network-side device. This method includes, but is not limited to, the following steps:

[0031] Step 11: Configure a search space for the terminal. The search space is associated with at least one Radio Network Temporary Identifier (RNTI). The RNTI is used for Cyclic Redundancy Check (CRC) of the PDCCH for scrambling multicast and / or broadcast services. Alternatively, the search space is associated with at least one multicast and / or broadcast service index.

[0032] In this invention, a search space corresponds to one or more RNTIs, and an RNTI corresponds to one multicast and / or broadcast service. Thus, a search space can correspond to one or more multicast and / or broadcast services, allowing multiple multicast and / or broadcast services to be configured with the same search space, freeing up more search space and improving resource utilization. Furthermore, each multicast and / or broadcast service corresponds to its own RNTI, enabling the terminal to distinguish between different multicast and / or broadcast services through RNTIs, reducing the terminal's detection complexity. In other words, this embodiment of the invention can configure the same search space for multiple multicast and / or broadcast services, with each multicast and / or broadcast service corresponding to its own RNTI. This eliminates the need for the terminal to detect all G-RNTIs on a single PDCCH detection opportunity, reducing the terminal's detection complexity. Optionally, all RNTIs corresponding to a search space belong to the same RNTI type.

[0033] Alternatively, a search space can correspond to one or more multicast and / or broadcast service indices. This also allows multiple multicast and / or broadcast services to be configured with the same search space, freeing up more search space for other services such as terminal-specific search spaces. This improves resource utilization and avoids the problems of reduced number of configurable search spaces and decreased scheduling flexibility in terminal-specific search spaces.

[0034] Optionally, the configuration information in this embodiment of the invention includes first configuration information corresponding to all RNTIs or all multicast and / or broadcast service indices associated with the search space. That is, the first configuration information is configuration information corresponding to all of at least one RNTI or all of at least one service index, or configuration information that applies to all of at least one RNTI or all of at least one service index. The first configuration information can be understood as the common configuration information of the search space, meaning that all PDCCHs configured in the search space for scheduling multicast and / or broadcast services can be detected using the first configuration information.

[0035] Optionally, the first configuration information includes at least one of the following configuration parameters:

[0036] The detection period of the Physical Downlink Control Channel (PDCCH);

[0037] PDCCH detection offset value;

[0038] Detection time length of PDCCH;

[0039] Aggregation level of the PDCCH candidate set;

[0040] The number of candidate sets for PDCCH;

[0041] DCI format.

[0042] Optionally, the configuration information in this embodiment may further include second configuration information corresponding to one of at least one RNTI or one of at least one multicast and / or broadcast service index. That is, the second configuration information is configuration information that corresponds to an RNTI or a service index, or configuration information that applies to an RNTI or service index. The second configuration information can be understood as dedicated configuration information for a specific multicast and / or broadcast service or RNTI in the search space. Specifically, each multicast and / or broadcast service or RNTI configured in the search space can correspond to its own dedicated configuration information, and a specific multicast and / or broadcast service or RNTI can only be detected using its corresponding second configuration information.

[0043] In other words, this approach takes into account the differences between various multicast and / or broadcast services. The configuration information of the search space may not be exactly the same for different multicast and / or broadcast services.

[0044] Optionally, the second configuration information includes at least one of the following configuration parameters:

[0045] The detection period of the Physical Downlink Control Channel (PDCCH);

[0046] PDCCH detection offset value;

[0047] Detection time length of PDCCH;

[0048] Aggregation level of the PDCCH candidate set;

[0049] The number of candidate sets for PDCCH;

[0050] DCI format.

[0051] The configuration parameters contained in the first and second configuration information are at least partially unique. That is, if multicast and / or broadcast services or RNTIs within a certain search space can use the same configuration parameters, the network-side device can configure only the first configuration information to reduce signaling overhead. If only some of the multicast and / or broadcast services or RNTIs within a certain search space require different configuration parameters, the network-side device can configure the second configuration information for some of the multicast and / or broadcast services or RNTIs, while the remaining multicast and / or broadcast services or RNTIs use the first configuration information to reduce signaling overhead. If only some of the multicast and / or broadcast services or RNTIs within a certain search space require different configuration parameters, the network-side device can configure the second configuration information, including some of the configuration parameters, for these multicast and / or broadcast services or RNTIs to reduce signaling overhead.

[0052] In the control channel configuration method of this invention, the network-side device configures configuration information for a search space for the terminal. This search space is associated with at least one Radio Network Temporary Identifier (RNTI), and each RNTI corresponds to its own multicast and / or broadcast service. Alternatively, the search space is associated with at least one multicast and / or broadcast service index. Thus, multiple multicast and / or broadcast services can be configured within a single search space, freeing up more search space and improving resource utilization.

[0053] The above describes an embodiment of the control channel configuration method for network-side devices. The control channel detection method for the terminal side will be further described below with reference to the accompanying drawings.

[0054] like Figure 2 As shown, an embodiment of the present invention provides a control channel detection method applied to a terminal, which includes, but is not limited to, the following steps:

[0055] Step 21: Receive configuration information of a search space from the network-side device. The search space is associated with at least one Radio Network Temporary Identifier (RNTI). The RNTI is used to scramble the Cyclic Redundancy Check (CRC) of the PDCCH for scheduling multicast and / or broadcast services. Alternatively, the search space is associated with at least one multicast and / or broadcast service index.

[0056] Optionally, the configuration information includes first configuration information for all RNTIs associated with the search space or for all multicast and / or broadcast service indexes, i.e., the common configuration information in the above network-side device embodiments.

[0057] Optionally, the first configuration information includes at least one of the following configuration parameters:

[0058] The detection period of the Physical Downlink Control Channel (PDCCH);

[0059] PDCCH detection offset value;

[0060] Detection time length of PDCCH;

[0061] Aggregation level of the PDCCH candidate set;

[0062] The number of candidate sets for PDCCH;

[0063] DCI format.

[0064] Optionally, the configuration information includes second configuration information corresponding to one of at least one RNTI or one of at least one multicast and / or broadcast service index, i.e., dedicated configuration information in the aforementioned network-side device.

[0065] Optionally, the second configuration information includes at least one of the following configuration parameters:

[0066] The detection period of the Physical Downlink Control Channel (PDCCH);

[0067] PDCCH detection offset value;

[0068] Detection time length of PDCCH;

[0069] Aggregation level of the PDCCH candidate set;

[0070] The number of candidate sets for PDCCH;

[0071] DCI format.

[0072] Optionally, the method further includes the following after step 21:

[0073] Step 22: Based on the configuration information, detect the target physical downlink control channel (PDCCH). The target PDCCH is either the PDCCH that schedules multicast and / or broadcast services with a specific index, or the PDCCH with a specific RNTI scrambled CRC.

[0074] Optionally, since there may be first configuration information (public configuration information) and second configuration information (private configuration information), it is necessary to define the priority of the two types of configuration information. Step 22 includes:

[0075] When the configuration information does not include the second configuration information, the target PDCCH is detected based on the first configuration information.

[0076] When the configuration information includes second configuration information, it can be further divided into the following cases:

[0077] When the second configuration information does not include specific configuration parameters, the target PDCCH is detected based on the specific parameters in the first configuration information;

[0078] Otherwise, the target PDCCH is detected based on the specific configuration parameters in the second configuration information;

[0079] The specific configuration parameters include at least one of the following: the detection period of the Physical Downlink Control Channel (PDCCH), the detection offset of the PDCCH, the detection time length of the PDCCH, the aggregation level of the PDCCH candidate set, the number of PDCCH candidate sets, and the DCI format.

[0080] In the control channel detection method of this invention, the terminal receives configuration information of a search space from the network-side device. This search space is associated with at least one Radio Network Temporary Identifier (RNTI), and each RNTI corresponds to its respective multicast and / or broadcast service. Alternatively, the search space is associated with at least one multicast and / or broadcast service index. Thus, multiple multicast and / or broadcast services can be configured within a single search space, freeing up more search space and improving resource utilization.

[0081] The above describes the implementation methods for configuring the control channel of network-side devices and detecting the control channel of terminals. The following will further describe the corresponding implementation methods for network-side devices or terminal products with reference to the accompanying drawings.

[0083] Configuration module 310 is used to configure configuration information of a search space for the terminal. The search space is associated with at least one wireless network temporary identifier (RNTI). The RNTI is used to scramble the cyclic redundancy check (CRC) of the PDCCH for scheduling multicast and / or broadcast services. Alternatively, the search space is associated with at least one multicast and / or broadcast service index.

[0084] Optionally, the configuration information includes first configuration information corresponding to all RNTIs or all multicast and / or broadcast service indexes associated with the search space.

[0085] Optionally, the first configuration information includes at least one of the following configuration parameters:

[0086] The detection period of the Physical Downlink Control Channel (PDCCH);

[0087] PDCCH detection offset value;

[0088] Detection time length of PDCCH;

[0089] Aggregation level of the PDCCH candidate set;

[0090] The number of candidate sets for PDCCH;

[0091] DCI format.

[0092] Optionally, the configuration information includes second configuration information corresponding to one of at least one RNTI or one of the at least one multicast and / or broadcast service index.

[0093] Optionally, the second configuration information includes at least one of the following configuration parameters:

[0094] The detection period of the Physical Downlink Control Channel (PDCCH);

[0095] PDCCH detection offset value;

[0096] Detection time length of PDCCH;

[0097] Aggregation level of the PDCCH candidate set;

[0098] The number of candidate sets for PDCCH;

[0099] DCI format.

[0100] Optionally, the configuration parameters contained in the first configuration information and the second configuration information are at least partially different.

[0128] The processor is used to control the transceiver to configure a search space for the terminal. The search space is associated with at least one Radio Network Temporary Identifier (RNTI), and each RNTI corresponds to its own multicast and / or broadcast service. Alternatively, the search space is associated with at least one multicast and / or broadcast service index.

[0129] The network-side device in this embodiment corresponds to the product embodiment of the control channel configuration method of the network-side device described above.

[0130] Another embodiment of the present invention includes a terminal, such as Figure 6 As shown, it includes a transceiver 610, a processor 600, a memory 620, and a program or instructions stored in the memory 620 and executable on the processor 600; when the processor 600 executes the program or instructions, it implements the above-mentioned control channel detection method applied to the terminal.

[0131] Transceiver 610 is used to receive and transmit data under the control of processor 600. Specifically, it is used to receive configuration information of a search space from network-side devices. The search space is associated with at least one Radio Network Temporary Identifier (RNTI), and each RNTI corresponds to its own multicast and / or broadcast service. Alternatively, the search space is associated with at least one multicast and / or broadcast service index.

[0134] The terminal in this embodiment corresponds to the product embodiment of the control channel detection method of the terminal described above. All implementations of the above method embodiments are applicable to this product embodiment and can achieve similar technical effects, so they will not be described in detail here.

[0135] An embodiment of the present invention provides a readable storage medium storing a program or instructions. When the program or instructions are executed by a processor, they implement the steps in the control channel configuration method on the network side or the control channel detection method on the terminal side as described above, and achieve the same technical effect.

For example, an identified executable code module may include one or more physical or logical blocks of computer instructions, which may be constructed as objects, procedures, or functions. Nevertheless, the executable code of the identified module does not need to be physically located together, but may include different instructions stored in different bits, which, when logically combined, constitute the module and achieve the module's intended purpose.

[0139] In practice, an executable code module can be a single instruction or many instructions, and can even be distributed across multiple different code segments, different programs, and across multiple memory devices. Similarly, operational data can be identified within the module and can be implemented in any suitable form and organized within any suitable type of data structure. This operational data can be collected as a single dataset or distributed across different locations (including different storage devices), and can exist, at least in part, solely as electronic signals within the system or network.

[0140] When a module can be implemented using software, considering the current level of hardware technology, modules that can be implemented in software can be implemented using hardware circuits by those skilled in the art to achieve the corresponding functions, without considering cost. These hardware circuits include conventional very-large-scale integrated circuits (VLSI) or gate arrays, as well as existing semiconductors such as logic chips and transistors, or other discrete components. Modules can also be implemented using programmable hardware devices, such as field-programmable gate arrays, programmable array logic, and programmable logic devices.

Many different forms and embodiments are feasible without departing from the spirit and teachings of the invention. Therefore, the invention should not be construed as limiting the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided to make the invention complete and convey the scope of the invention to those skilled in the art.
