[0168] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0169] It should be noted that, in this document, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0170] It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if" as used herein may be interpreted as "when," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the described features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will occur only when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0171] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are shown in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence in the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be performed in other orders. Moreover, at least a portion of the steps in the figure may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with at least a portion of other steps or sub-steps or stages of other steps.

[0172] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to the determination" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)," depending on the context.

[0173] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0205] Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0206] In some implementations, a network device transmits a downlink channel to a terminal device, which can receive the downlink channel on specific frequency domain resources. When receiving the downlink channel, the terminal device can perform single reception or repeated reception. However, during the above process, the terminal device cannot determine when to perform single reception or repeated reception, resulting in the terminal device being unable to determine the reception mode for receiving the downlink channel; and / or, when performing single reception or repeated reception using a search space set, the efficiency of determining the search space set is low.

[0207] To solve the above technical problems, embodiments of the present application provide a control method, a communication device, and a storage medium, which can add or reuse fields in downlink information, and the terminal device determines the reception mode and / or monitoring mode of the downlink channel based on the fields in the downlink information. In this way, since the reception mode and / or monitoring mode of the downlink channel can be indicated by the fields, the terminal device can determine the reception mode and / or monitoring mode of the downlink channel based on the downlink information; and / or the terminal device can determine the search space set based on the reception mode and / or monitoring mode of the downlink channel, thereby improving the efficiency of determining the search space set.

[0208] In order to facilitate understanding of the technical solution of the present application, the concepts involved in the present application are first explained below.

[0209] Radio Resource Control (RRC): refers to the management, control, and scheduling of radio resources through specific strategies and methods. Network devices send RRC signaling to terminal devices.

[0210] Downlink Control Information (DCI): Downlink control information sent by network equipment to terminal equipment through the Physical Downlink Control Channel (PDCCH), which may include uplink and downlink resource allocation, Hybrid Automatic Repeat reQuest process number (Hybrid Automatic Repeat reQuest) information, power control, etc.

[0211] Transmission Configuration Indication (TCI) state: The TCI state can be used to provide Quasi Co-Location (QCL) information. The terminal device determines the PDCCH receive beam based on the QCL information to receive or monitor the PDCCH.

[0212] The TCI state mode can be divided into uplink and downlink combined (ioint) mode and uplink and downlink independent (separate) mode, among which,

[0213] The joint uplink and downlink mode uses a combined TCI state configuration for both uplink and downlink. The combined TCI state is derived from the TCI-State parameter. This determines the downlink receive beam and uplink transmit beam based on the combined TCI state source reference signal.

[0214] Independent uplink and downlink mode configures the downlink (DL) TCI state and the uplink (UL) TCI state independently. The DL TCI state is derived from TCI-State, which determines the downlink receive beam based on the DL TCI state source reference signal. The UL TCI state is derived from TCI-UL-State-r17, which determines the uplink transmit beam based on the UL TCI state source reference signal.

[0215] Optionally, the network device may activate some TCI states, and the activated TCI states may be used for PDCCH reception or monitoring.

[0216] Next, the activation TCI state will be described with reference to FIG5 .

[0217] Figure 5 is a schematic diagram of activating TCI states provided in an embodiment of the present application. As shown in Figure 5, the TCI state pool may include multiple TCI states. K (0≤K≤8) TCI code points are selected from the TCI state pool for activation according to MAC CE signaling. For any TCI code point, the TCI code point can correspond to 1 or 2 TCI states. If a TCI code point corresponds to 1 TCI state, the 1 TCI state can be 1 UL TCI state, or 1 DL TCI state, or 1 joint TCI state; if a TCI code point corresponds to 2 TCI states, the 2 TCI states can be DL TCI state and UL TCI state, respectively.

[0218] Optionally, for a scenario with a single DCI and multiple transmission and reception points (network devices), one TCI code point may correspond to one or two TCI states or three TCI states or four TCI states. If the TCI code point corresponds to 1 TCI state, then the 1 TCI state can be 1 UL TCI state, or 1 DL TCI state, or 1 combined TCI state; if the TCI code point corresponds to 2 TCI states, then the 2 TCI states can be the DL TCI state and UL TCI state corresponding to one network device, or two network devices each correspond to one TCI state, that is, any one of the DL TCI state, UL TCI state, and combined TCI state; if the TCI code point corresponds to 3 TCI states, one network device corresponds to 1 TCI state, that is, any one of the DL TCI state, UL TCI state, and combined TCI state, and the other network device corresponds to 2 TCI states, that is, DL TCI state and UL TCI state; if the TCI code point corresponds to 4 TCI states, each network device corresponds to 2 TCI states, that is, DL TCI state and UL TCI state.

[0219] Optionally, one TCI code point is selected from the K activated TCI code points according to the DCI, and a corresponding TCI state is obtained from the TCI code point. The TCI state can be used by the terminal device to receive and / or monitor the PDCCH.

[0220] Media Access Control-Control Element (MAC CE): This element is used to convert logical channels into physical channels, including channel conversion, priority processing, and scheduling management. Network devices send MAC CE signaling to terminal devices to exchange MAC layer control information with them.

[0221] The content of the MAC CE signaling is described below with reference to FIG. 6 .

[0222] Figure 6 is a schematic diagram of MAC CE signaling provided in an embodiment of the present application. As shown in Figure 6, the MAC CE signaling may include N+3 bytes (Octet, Oct), namely Oct 1, Oct 2, Oct 3, Oct 4, Oct 5, ..., OctN+3. Optionally, the byte length of any Oct is 8 bits.

[0223] For example, Oct 1 may include an R field, a serving cell identifier (Serving Cell ID) field, and a downlink bandwidth part identification (DL BWP ID) field. Optionally, the R field is a reserved field with a field length of 1 bit; the serving cell identifier field may be used to indicate the serving cell ID to which the MAC CE applies, that is, the physical cell identifier of the serving cell, and the length of this field may be 5 bits; the DL BWP ID field may be used to indicate the downlink bandwidth to which the MAC CE applies, and the length of this field may be 2 bits.

[0224] Oct 3 can include eight P fields: P1, P2, P3, ..., P8, each with a length of 1 bit. For any Pi field, it can be used to indicate one or more TCI states corresponding to each TCI code point. Optionally, if the Pi field is 1, it can indicate that the i-th TCI code point corresponds to two TCI states: the DL TCI state and the UL TCI state. If the Pi field is 0, it can indicate that the i-th TCI code point corresponds to one TCI state, either the DL TCI state or the UL TCI state.

[0225] Oct 4 may include a D / U (Down / Up) field and a TCI state ID field. Optionally, the D / U field may be used to indicate whether the TCI state in the byte is used for downlink reception / monitoring or uplink reception. If the D / U field is 1, the TCI state in the byte is used for uplink and downlink combined or downlink reception / monitoring; if the D / U field is 0, the TCI state in the byte is used for uplink reception. The TCI state ID may be used to identify the ID of the TCI state. If the D / U field is 1, a 7-bit TCI state ID may be used; if the D / U field is 0, the most significant bit of the TCI state ID is a reserved bit, and the remaining 6 bits are the UL TCI State ID specified by the protocol.

[0226] It should be noted that the maximum number of active TCI states is 16, that is, N is 16. One TCI code point can correspond to two TCI states. For example, if N is 16, the two TCI states corresponding to TCI code point -1 can be identified by TCI state ID 1 in Oct 4 and TCI state ID 2 in Oct 5, ..., and the two TCI states corresponding to TCI code point -8 can be identified by TCI state ID 15 in Oct 18 and TCI state ID 16 in Oct 19.

[0227] Below, the application scenarios of the embodiments of the present application are introduced in conjunction with Figures 7A to 7C.

[0228] FIG7A is a schematic diagram of an application scenario provided by an embodiment of the present application. Referring to FIG7A , a network device and a terminal device are included. The network device and the terminal device can communicate with each other.

[0229] The network device can send information to the terminal device through PDCCH-1. The terminal device can receive or monitor PDCCH-1 once on a specific time-frequency domain resource to receive information. The network device can be called a transmission reception point (Transmission / Reception Point, TRP), and this method of receiving or monitoring the PDCCH sent by a single network device can be called single reception or monitoring. In particular, if there are multiple network devices, any one of the network devices can send information to the terminal device through PDCCH-1, and the terminal device can receive or monitor PDCCH-1 once on a specific time-frequency domain resource to receive information. In this case, the method of receiving or monitoring the PDCCH sent by a single network device can also be called single reception or monitoring.

[0230] FIG7B is a second schematic diagram of an application scenario provided by an embodiment of the present application. Referring to FIG7B , network device 1, network device 2, and terminal device are included. Network device 1 and network device 2 can communicate with terminal device respectively.

[0231] Network device 1 can send information to the terminal device via PDCCH-1, and network device 2 can send information to the terminal device via PDCCH-2. The terminal device can repeatedly receive or monitor PDCCH-1 and PDCCH-2 on specific time-frequency domain resources to receive information. Network device 1 and network device 2 can be transmission reception points. This method of receiving or monitoring PDCCHs sent by multiple network devices can be called repeated reception or monitoring.

[0232] FIG7C is a third schematic diagram of an application scenario provided by an embodiment of the present application. Referring to FIG7C , network device 1, network device 2, and terminal device 102 are included. Network device 1 and network device 2 can communicate with terminal device 102 respectively.

[0233] Network device 1 can send information to the terminal device via the Physical Downlink Share Channel (PDSCH)-1, and network device 2 can send information to the terminal device via PDSCH-2. The terminal device can receive PDSCH-1 and PDSCH-2 on specific time-frequency domain resources, that is, it can perform repeated reception. Network device 1 and network device 2 can be transmission receiving points. This method of receiving PDSCHs sent by multiple network devices can be called multi-receiver opportunity reception.

[0234] The technical solutions shown in this application are described in detail through specific embodiments. Optionally, the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be repeated in different embodiments.

[0235] FIG8 is a flow chart of a control method provided in an embodiment of the present application. Referring to FIG6 , the method may include:

[0236] S801. The network device sends downlink information to the terminal device.

[0237] Downlink information may include DCI and MAC CE signaling.

[0238] Optionally, the network device can remotely schedule each terminal device via DCI. The network device and the terminal device can exchange control information about the MAC layer via MAC CE signaling.

[0239] Optionally, the network device may send DCI and / or MAC CE signaling to the terminal device via a wireless network.

[0240] S802: The terminal device determines a receiving mode and / or a monitoring mode of a downlink channel according to the downlink information.

[0241] The receiving mode of the downlink channel can be single reception or repeated reception; the monitoring mode of the downlink channel can be single monitoring or repeated monitoring.

[0242] Optionally, in order to improve the reception reliability of the PDCCH, the reception mode of the downlink channel may be switched from single reception to repeated reception, or the monitoring mode of the downlink channel may be switched from single monitoring to repeated monitoring.

[0243] Optionally, in order to flexibly indicate the receiving mode and / or monitoring mode of the downlink channel of the terminal device, a new or reused field can be added to the downlink information to indicate the receiving mode and / or monitoring mode of the downlink channel through the field.

[0244] Optionally, after receiving the downlink information, the terminal device may decode the downlink information to determine the fields in the downlink information, thereby determining the receiving mode and / or monitoring mode of the downlink channel according to the fields in the downlink information.

[0245] In an embodiment of the present application, a network device sends downlink information to a terminal device. After receiving the downlink information, the terminal device determines the receiving mode and / or monitoring mode of the downlink channel based on the downlink information. Because the downlink information may include a newly added / reused field, the field can be used to indicate the receiving mode and / or monitoring mode of the downlink channel. Therefore, the terminal device determines the receiving mode and / or monitoring mode of the downlink channel based on the field in the downlink information.

[0246] The following describes in detail the fields added or reused in the downlink information in step S802. Optionally, a field added or reused in the DCI using methods 1 and 2 can be used to directly indicate the PDCCH reception mode or monitoring mode and / or the PDSCH reception mode; a field added or reused in the DCI using methods 3 and 4 can be used to indirectly indicate the PDCCH reception mode or monitoring mode; and a field added or reused in the MAC CE signaling using methods 5 and 6 can be used to indicate the PDCCH reception mode or monitoring mode.

[0247] Mode 1: The DCI may include a first field, and the first field may be used to indicate a PDCCH reception mode or monitoring mode.

[0248] Optionally, the DCI may be composed of multiple fields, each field occupying a different number of bits. For example, the DCI may be multi-bit information composed of 26 fields.

[0249] Optionally, a first field may be added to the DCI, and the first field may be a 1-bit field.

[0250] Optionally, it can be set that when the first field is a first value, the first field is used to indicate that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; when the first field is a second value, the first field is used to indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, and vice versa.

[0251] Optionally, the first value may be 0; the second value may be 1.

[0252] For example, a new first field can be added to the DCI. When the first field is 0, it can be used to indicate that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; and / or, when the first field is 1, it can be used to indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, and vice versa.

[0253] Optionally, if the DCI does not carry downlink resource allocation information, a 1-bit field in the DCI may be reparsed to reuse the 1-bit field in the DCI and used as the first field to indicate a PDCCH reception mode or monitoring mode.

[0254] For example, the multiplexed field in the DCI may be a DMRS sequence initialization field or a minimum applicable scheduling offset indicator field. The multiplexed field may be used as the first field. When the multiplexed field is 0, it may be used to indicate that the PDCCH reception mode is PDCCH single reception or the PDCCH monitoring mode is PDCCH single monitoring; and / or, when the multiplexed field is 1, it may be used to indicate that the PDCCH reception mode is PDCCH repeated reception or the PDCCH monitoring mode is PDCCH repeated monitoring.

[0255] Optionally, if the DCI does not carry downlink resource allocation information, a multi-bit field in the DCI may be reparsed to reuse a 1-bit in the multi-bit field and use the multi-bit field as the first field to indicate a PDCCH reception mode or monitoring mode.

[0256] For example, the multi-bit field may be a Hybrid Automatic Repeat reQuest process number (HARQ process number) field, and the HARQ process number field may be the first field. The 1 bit may be the least significant 1 bit or the most significant 1 bit.

[0263] Mode 2: The DCI may include a second field, and the second field may be used to indicate a PDCCH reception mode or a monitoring mode and / or a PDSCH reception mode.

[0264] Optionally, the second field may be a 2-bit field newly added in the DCI.

[0265] Optionally, it can be set that when the second field is a third value, the second field can be used to indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring; and / or, when the second field is a fourth value, the second field is used to indicate that the PDSCH reception mode is PDSCH multiple receiver opportunities reception; and / or, when the second field is a fifth value, the second field is used to indicate that the PDCCH reception mode is repeated reception, or the PDCCH monitoring mode is repeated monitoring and the PDSCH reception mode is PDSCH multiple receiver opportunities reception.

[0273] Optionally, it can be set that when the third field is the third value or the fourth value, the third field can be used to indicate that the first quantity is 1; when the third field is the fifth value or the sixth value, the third field is used to indicate that the first quantity is 2.

[0274] Optionally, the data format of the third value, the fourth value, the fifth value, and the sixth value may be in binary format. For example, the third value may be 00, the fourth value may be 01, the fifth value may be 10, and the sixth value may be 11.

[0276] For example, the value of the third field, the corresponding first quantity, and the corresponding indication content may be as shown in Table 2:

[0277] Table 2

[0278]

[0279] Optionally, the first TCI state and the second TCI state may both be a joint TCI state in an uplink and downlink joint mode, or a DL TCI in an uplink and downlink independent mode; or may be a joint TCI state in an uplink and downlink joint mode and a DL TCI state in an uplink and downlink independent mode, respectively. The first TCI state and the second TCI state may be TCI states used by the terminal device for downlink channel reception and / or monitoring.

[0280] Optionally, if the PDCCH reception mode is single reception, or the PDCCH monitoring mode is single monitoring, then one TCI state, i.e., the first TCI state or the second TCI state, can be used for a single reception / monitoring opportunity of the PDCCH; if the PDCCH reception mode is repeated reception, or the PDCCH monitoring mode is repeated monitoring, then two TCI states, i.e., the first TCI state and the second TCI state, can be used for repeated reception opportunities or repeated monitoring opportunities of the PDCCH.

[0281] Mode 4: The DCI may include a fourth field, and the fourth field is used to indicate the second number of TCI states used for PDCCH reception or monitoring.

[0284] Optionally, if the fourth field is a first numerical value, it can be used to indicate that the second quantity is 1; if the fourth field is a second numerical value, it can be used to indicate that the second quantity is 2.

[0285] Optionally, the data format of the first value and the second value may be binary format. For example, the first value may be 0 and the second value may be 1.

[0286] Optionally, if the second number is 1, it can be used to indicate that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; and / or, if the second number is 2, it can be used to indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring.

[0287] For example, the value of the fourth field, the corresponding second quantity, and the corresponding indication content may be as shown in Table 3:

[0288] Table 3

[0289]

[0290] The above-mentioned method 3 and method 4 can indirectly indicate the reception method or monitoring method of PDCCH, that is, the first number of activated TCI states or the second number of used TCI states can be indicated by a field, and then the reception method or monitoring method of PDCCH can be indicated by the first number or the second number.

[0291] It should be noted that before using mode 3 and mode 4 to indicate the PDCCH reception mode or monitoring mode, the following two judgment methods can be used to determine whether the PDCCH reception mode or monitoring mode is supported for switching.

[0292] Judgment method 1: Add a parameter in the RRC signaling, which is used to indicate whether the PDCCH reception mode or monitoring mode is switched.

[0293] If the parameter indicates that the PDCCH reception mode or monitoring mode can be switched, mode 3 and mode 4 can be used to indicate the PDCCH reception mode or monitoring mode after the switch; if the parameter indicates that the PDCCH reception mode or monitoring mode cannot be switched, there is no need to use mode 3 and mode 4 to indicate the PDCCH reception mode or monitoring mode after the switch.

[0294] Judgment method 2: whether the search space connection parameters are configured by the search space set configured by RRC, and whether the PDCCH reception mode or monitoring mode is supported for switching.

[0295] If the search space set configured by RRC is configured with search space connection parameters, it is considered that the PDCCH reception mode or monitoring mode can be supported for switching, and mode 3 and mode 4 can be used to indicate the PDCCH reception mode or monitoring mode after switching; if the search space set configured by RRC is not configured with search space connection parameters, it is considered that the PDCCH reception mode or monitoring mode is not supported for switching, and there is no need to indicate the PDCCH reception mode or monitoring mode after switching through mode 3 and mode 4.

[0296] It should be noted that when using Mode 3 and Mode 4, there may be a mapping relationship between the first TCI state and the second TCI state and the control resource set (CORESET). Optionally, mapping is performed according to the TCI state and the CORESET number. For example, the first TCI state can be associated with the first CORESET, and the second TCI state can be associated with the second CORESET; optionally, the TCI state and the CORESET are also mapped according to the time order determined by the CORESET and its corresponding search space set. For example, if the determination time of the first CORESET is earlier than the determination time of the second CORESET, the first TCI state can be associated with the first CORESET, and the second TCI state can be associated with the second CORESET.

[0297] Mode 5: multiplex the fifth field in the MAC CE signaling. The fifth field can be used to indicate the reception mode or monitoring mode of the PDCCH.

[0298] Optionally, the fifth field may be any R field in the MAC CE signaling in Figure 4. For example, the fifth field may be the leftmost R field of Oct1 or the rightmost R field of Oct2 in Figure 4. The fifth field may be a 1-bit field.

[0299] Optionally, if the fifth field is a first value, it can be used to indicate that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; if the fifth field is a second value, it is used to indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, and vice versa.

[0300] Optionally, the data format of the first value and the second value may be binary format. For example, the first value may be 0, and the second value may be 1.

[0301] For example, if the fifth field is an R field in the MAC CE signaling, if the R field is 0, it can be used to indicate that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; and / or, if the R field is 1, it can be used to indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, and vice versa.

[0302] Method 6: Add a new field in the MAC CE signaling to indicate the receiving mode and / or monitoring mode of the downlink channel.

[0303] Optionally, the MAC CE signaling may include a sixth field and a seventh field, and the sixth field and the seventh field may be used to indicate a receiving mode or a monitoring mode of the PDCCH.

[0304] Optionally, the sixth field and the seventh field may both be 1-bit fields.

[0305] Optionally, the sixth field and the seventh field may correspond to two TCI states for downlink transmission respectively.

[0306] Optionally, if the values ​​indicated by the sixth field and the seventh field are the same, the sixth field and the seventh field can be used to indicate that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; and / or, if the values ​​indicated by the sixth field and the seventh field are different, the sixth field and the seventh field can be used to indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring.

[0307] For example, if the sixth field and the seventh field are both 0 or both 1, it can indicate that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; and / or, if the sixth field is 0 and the seventh field is 1, it can indicate that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring.

[0308] Optionally, the design of the sixth field and the seventh field may include the following two design methods:

[0309] Design method 1: All TCI code points uniformly use the sixth and seventh fields.

[0310] Optionally, all TCI code points correspond to one sixth field and one seventh field, wherein the one sixth field corresponds to the first TCI state of all TCI code points, and the one seventh field corresponds to the second TCI state of all TCI code points.

[0311] For example, the sixth field and the seventh field corresponding to all TCI code points may be as shown in Table 4:

[0312] Table 4

[0313]

[0314] Design method 2: Each TCI code point corresponds to one sixth field and one seventh field.

[0315] Optionally, the sixth field of each TCI code point corresponds to the first TCI state of the TCI code point, and the seventh field corresponds to the second TCI state of the TCI code point.

[0316] For example, the sixth field and the seventh field corresponding to each TCI code point may be as shown in Table 5:

[0317] Table 5

[0318]

[0319] Since a maximum of eight TCI code points can be activated, each TCI code point can correspond to at most two TCI states, namely the first TCI state and the second TCI state. Therefore, the sixth field corresponding to all TCI code points has a maximum of eight entries, and the seventh field has a maximum of eight entries.

[0320] Optionally, when using mode 6 to indicate the receiving mode and / or monitoring mode of the downlink channel, for any TCI state, if the sixth field or the seventh field corresponding to the TCI state is 0, the TCI state can be associated with the first CORESET; and / or, if the sixth field or the seventh field corresponding to the TCI state is 1, the TCI state can be associated with the second CORESET.

[0321] It should be noted that in any of the above methods, when PDCCH is repeatedly received or repeatedly monitored, and / or PDSCH is received in multiple reception opportunities, there are two TCI states for downlink reception or monitoring. The two TCI states can be the first TCI state and the second TCI state respectively. The first TCI state and the second TCI state can both be the joint TCI state in the uplink and downlink joint mode, or the DL TCI in the uplink and downlink independent mode; or they can be the joint TCI state in the uplink and downlink joint mode and the DL TCI state in the uplink and downlink independent mode respectively. The two TCI states, i.e., the first TCI state and the second TCI state, can be used for repeated reception opportunities or repeated monitoring opportunities of PDCCH; or, the two TCI states, i.e., the first TCI state and the second TCI state, can be used for multiple reception opportunities of PDSCH.

[0322] Optionally, the format of the DCI may be a UE-specific DCI format or a common DCI format. For example, the UE-specific DCI format may be DCI 1_1 / 1_2, and the common DCI format may be DCI 2_x.

[0323] Optionally, the terminal device may determine the PDCCH reception mode or monitoring mode and / or PDSCH reception mode through any one of the above six methods.

[0324] Optionally, after determining the PDCCH reception mode or monitoring mode, the terminal device may receive or monitor the PDCCH using a search space set. However, in related art, when the terminal device receives or monitors the PDCCH, determining the search space set is inefficient.

[0325] 9 , the present application provides a method for determining a search space set to improve the efficiency of determining the search space set.

[0326] FIG9 is a flow chart of a method for determining a search space set according to an embodiment of the present application. Referring to FIG9 , the method may include:

[0327] S901. The terminal device determines a search space set used by the PDCCH according to a PDCCH reception mode or monitoring mode.

[0328] Optionally, the PDCCH reception mode may include single reception or repeated reception; the PDCCH monitoring mode may include single monitoring or repeated monitoring.

[0329] Optionally, the search space set may include a first search space set and a second search space set; a search space connection parameter (SearchSpaceLinkingId) may be configured between the first search space set and the second search space set.

[0330] Optionally, the search space set may include a third search space set. The third search space set may be different from the first search space set or the second search space set; the third search space set may be the first search space set or the second search space set.

[0331] The search space set is described below with reference to FIG. 10A and FIG. 10B .

[0332] Figure 10A is a schematic diagram of a search space set provided in an embodiment of the present application. Referring to Figure 10A , the search space set may include n first search space sets, n second search space sets, and m third search space sets (n, m are positive integers).

[0333] Optionally, the first search space set-1 and the second search space set-1, the first search space set-2 and the second search space set-2, ..., the first search space set-n and the second search space set-n are each connected in pairs using a search space connection parameter. No search space connection parameter is configured for the third search space set-1, the third search space set-2, ..., and the third search space set-m.

[0334] FIG10B is a second schematic diagram of a search space set provided in an embodiment of the present application. Referring to FIG10B , the search space set may include a first search space set group and a second search space set group.

[0335] The first search space set group may include the first search space set-1 and the second search space set-1, ..., the first search space set-n and the second search space set-n, and the first search space set-1 and the second search space set-1, ..., the first search space set-n and the second search space set-n are respectively connected in pairs through search space connection parameters.

[0336] The second search space set group may include a third search space set-1, a third search space set-2, ..., and a third search space set-m, and no search space connection parameter is configured for any of them.

[0337] Optionally, the third search space set may also be any one of the first search space set or the second search space set in FIG. 10A or FIG. 10B .

[0338] Optionally, if the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, the search space set used by PDCCH may include the first search space set and the second search space set as shown in Figure 10A; or, it may include the first search space set and the second search space set in the first search space set group as shown in Figure 10B.

[0339] Optionally, if the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring, the search space set used by PDCCH can be the third search space set as shown in Figure 10A; or, it can be the third search space set in the second search space set group in Figure 10B; it can also be any one of the first search space set or second search space set in Figure 10A or Figure 10B.

[0340] S902: The network device sends a PDCCH according to a search space set.

[0341] Optionally, the network device may determine a configured search space set according to RRC signaling, so as to perform single transmission or repeated transmission of the PDCCH according to the search space set.

[0342] Optionally, if PDCCH is repeatedly sent, the search space set used to send PDCCH may include the first search space set and the second search space set as shown in Figure 10A; or, it may include the first search space set and the second search space set in the first search space set group as shown in Figure 10B.

[0343] Optionally, if PDCCH is sent once, the search space set used to send PDCCH can be the third search space set as shown in Figure 10A; or, it can be the third search space set in the second search space set group in Figure 10B; or it can be any one of the first search space set or second search space set as shown in Figure 10A or Figure 10B.

[0344] S903: The terminal device receives or monitors the PDCCH according to the search space set.

[0345] Optionally, for any search space set, the search space set has a corresponding control resource set CORESET.

[0346] Optionally, for any CORESET, the CORESET has a corresponding TCI state.

[0347] Optionally, if the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, the terminal device can use the corresponding two TCI states to receive or monitor the PDCCH in the first search space set and the second search space set configured with search space connection parameters, and the resources determined by the CORESET corresponding to the first search space set and the second search space set; if the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring, the terminal device can use the corresponding one TCI state to receive or monitor the PDCCH in a third search space set and the resources determined by the CORESET corresponding to the third search space set.

[0348] Optionally, the terminal device may receive PDCCH using a new PDCCH reception method or monitor PDCCH using a new PDCCH monitoring method starting from the first moment and / or symbols after the first moment according to the search space set and the corresponding CORESET.

[0349] Optionally, the first moment may be the first symbol after reporting feedback information and passing beam application time (beamApp Time), or the first symbol after decoding the DCI indicating the PDCCH reception mode or monitoring mode and passing N symbols.

[0350] Feedback information includes Acknowledgement (ACK) and Negative Acknowledgement (NACK). ACK is a form of positive feedback, meaning the receiver can reply to the sender after receiving the data. NACK is a form of negative feedback, meaning the receiver only notifies the sender if the data was not received or a decoding error occurred.

[0351] The value range of the beam application time can be {1, 2, 4, 7, 14, 28, 42, 56, 70, 84, 98, 112, 224, 336}, and the unit is symbol.

[0352] Next, the first moment will be described with reference to FIG. 11A and FIG. 11B .

[0353] Figure 11A is a schematic diagram of the first moment provided by an embodiment of the present application. Referring to Figure 11A, the intelligent terminal can receive PDCCH and parse out the downlink information carried by PDCCH. If the field in the downlink information indicates that the reception mode of PDCCH is switched to repeated reception, after the parsing is successful, the terminal device can report ACK through the physical uplink control channel (Physical UPlink Control Channel, PUCCH) or the physical uplink shared channel (Physical UPlink Share Channel, PUSCH). The first symbol after the last symbol of PUCCH / PUSCH and the beam application time (beamAppTime) symbols can be determined as the first moment, as shown in Figure 11A. After the first moment, the new PDCCH reception / monitoring mode can be applied on the reception / monitoring opportunity of the first PDCCH, that is, repeated reception / monitoring is performed through PDCCH-1 and PDCCH-2.

[0354] Figure 11B is a second schematic diagram of the first moment provided by an embodiment of the present application. Referring to Figure 11B, the terminal device can receive the PDCCH and parse out the downlink information carried by the PDCCH. If the field in the downlink information indicates that the PDCCH reception mode is switched to repeated reception, the first moment can be determined as the first symbol starting from the last symbol of the PDCCH and after N symbols, as shown in Figure 11B. After the first moment, the new PDCCH reception mode can be applied at the reception / monitoring opportunity of the first PDCCH, that is, repeated reception / monitoring can be performed through PDCCH-1 and PDCCH-2.

[0355] In an embodiment of the present application, a network device may send a PDCCH to a terminal device based on a search space set, and the terminal device may determine the search space set based on a PDCCH reception mode or monitoring mode, and may then receive or monitor the PDCCH based on the search space set. Since different PDCCH reception modes or monitoring modes may be associated with different search space sets, the terminal device may determine the search space set based on the PDCCH reception mode or monitoring mode, thereby improving the efficiency of determining the search space set.

[0356] Next, based on the embodiments shown in FIG. 8 and FIG. 9 and in combination with FIG. 12 , the above control method will be further described.

[0357] FIG12 is a flow chart of another control method provided in an embodiment of the present application. Referring to FIG12 , the method may include:

[0358] S1201. The network device sends downlink information to the terminal device.

[0359] Optionally, the downlink information may include DCI and MAC CE signaling.

[0360] Optionally, the network device may send DCI and / or MAC CE signaling to the terminal device via a wireless network.

[0361] S1202. The terminal device determines a PDCCH reception mode and / or monitoring mode according to the downlink information.

[0362] Optionally, the PDCCH reception mode may include single reception or repeated reception; the PDCCH monitoring mode may include single monitoring or repeated monitoring.

[0363] Optionally, in order to improve the reception reliability of the PDCCH, the reception mode of the downlink channel may be switched from single reception to repeated reception, or the monitoring mode of the downlink channel may be switched from single monitoring to repeated monitoring.

[0364] Optionally, in order to flexibly indicate the receiving mode and / or monitoring mode of the downlink channel of the terminal device, a new or reused field can be added to the downlink information to indicate the receiving mode and / or monitoring mode of the downlink channel through the field.

[0365] Optionally, if the downlink information includes DCI, a new or reused field in the DCI can be added through the above-mentioned method 1 and method 2 to directly indicate the reception mode or monitoring mode of the PDCCH and / or the reception mode of the PDSCH; a new or reused field in the DCI can be added through the above-mentioned method 3 and method 4 to indirectly indicate the reception mode or monitoring mode of the PDCCH.

[0366] Optionally, if the downlink information includes MAC CE signaling, different fields may be added or reused in the MAC CE signaling through the above-mentioned method 5 and method 6.

[0367] The terminal device may decode the downlink information to determine the fields in the downlink information, and thereby determine the receiving mode and / or monitoring mode of the downlink channel according to the fields in the downlink information.

[0368] For example, if the downlink information received by the terminal device is DCI, the DCI can be decoded. If it is determined that the DCI includes a first field, if the first field is 0, the terminal device can determine that the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring; if the first field is 1, the terminal device can determine that the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring.

[0369] S1203: The terminal device determines a search space set used by the PDCCH according to a PDCCH reception mode or monitoring mode.

[0370] Optionally, different PDCCH reception modes or monitoring modes may correspond to different search space sets.

[0371] Optionally, if the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring, the corresponding search space set can be the third search space set in Figure 10A; or, it can also be the third search space set in the second search space set group in Figure 10B; it can also be any one of the first search space set or second search space set in Figure 10A or Figure 10B.

[0372] Optionally, if the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, the search space set used by PDCCH may include the first search space set and the second search space set as shown in Figure 10A; or, it may include the first search space set and the second search space set in the first search space set group as shown in Figure 10B.

[0373] For example, if the terminal device determines that the PDCCH reception mode is PDCCH repeated reception, the terminal device can determine that the search space set includes a first search space set and a second search space set, and the first search space set and the second search space set are configured with search space connection parameters.

[0374] S1204: The network device sends a PDCCH according to the search space set.

[0375] Optionally, the network device may perform single or repeated transmission of the PDCCH according to a search space set determined according to a PDCCH reception mode and / or monitoring mode.

[0376] Optionally, the network device may transmit the PDCCH according to the search space set and the corresponding control resource set, so that the terminal device may start receiving or monitoring the PDCCH at the first moment and / or symbols after the first moment.

[0377] For example, the network device repeatedly sends PDCCH according to the first search space set and the second search space set configured with search space connection parameters as shown in Figure 10A; or, the network device sends PDCCH once according to the third search space set not configured with search space connection parameters as shown in Figure 10A.

[0378] S1205. The terminal device receives or monitors the PDCCH according to the search space set.

[0379] Optionally, for any search space set, the search space set has a corresponding control resource set CORESET.

[0380] Optionally, for any CORESET, the CORESET has a corresponding TCI state.

[0381] Optionally, if the PDCCH reception mode is PDCCH repeated reception, or the PDCCH monitoring mode is PDCCH repeated monitoring, the terminal device can use the corresponding two TCI states to receive or monitor PDCCH in the first search space set and the second search space set configured with search space connection parameters, and the resources determined by the CORESET corresponding to the first search space set and the second search space set.

[0382] Optionally, if the PDCCH reception mode is PDCCH single reception, or the PDCCH monitoring mode is PDCCH single monitoring, the terminal device can use a corresponding TCI state to receive or monitor PDCCH in a third search space set and the resources determined by the CORESET corresponding to the third search space set.

[0383] Optionally, the terminal device may receive PDCCH using a new PDCCH reception method or monitor PDCCH using a new PDCCH monitoring method starting from the first moment and / or symbols after the first moment according to the search space set and the corresponding CORESET.

[0384] For example, if the terminal device determines that the PDCCH reception mode is PDCCH repeated reception, and according to the PDCCH repeated reception mode, it can be determined that the search space set includes a first search space set and a second search space set, and the first search space set corresponds to the first CORESET, and the first CORESET corresponds to the first TCI state; the second search space set corresponds to the second CORESET, and the second CORESET corresponds to the second TCI state, then the terminal device can use the first TCI state to receive PDCCH according to the first search space set and the resources determined by the first CORESET, and can use the second TCI state to receive PDCCH according to the second search space set and the resources determined by the second CORESET, so as to perform repeated reception of PDCCH.

[0385] In an embodiment of the present application, a network device sends downlink information to a terminal device. After receiving the downlink information, the terminal device determines the receiving mode and / or monitoring mode of the downlink channel according to the downlink information. The network device sends PDCCH according to the search space set, and the terminal device can determine the search space set used by PDCCH according to the receiving mode and / or monitoring mode of PDCCH, and receive and / or monitor PDCCH according to the search space set. Since the downlink information may include a newly added / reused field, the field can be used to indicate the receiving mode and / or monitoring mode of the downlink channel; and since different PDCCH receiving modes and / or monitoring modes can be associated with different search space sets. Combining these two points, the terminal device can determine the receiving mode and / or monitoring mode of the downlink channel according to the field in the downlink information, and improve the efficiency of determining the search space set.
