[0013] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be described in more detail below in conjunction with the accompanying drawings.

[0014] FIG. 1 shows a schematic diagram of PDCCH processing provided by an exemplary embodiment of the related art.

[0015] A control resource set (CORESET) is a time-frequency resource used by a terminal device to decode possible PDCCHs using one or more search spaces. A control resource set maps a set of resource unit groups (Resource Element Groups, REGs) to a set of control channel units (Control Channel Elements, CCEs) through a CCE-to-REG mapping. Each REG contains a resource block of one OFDM symbol.

[0016] A CCE is a unit of a search space when a terminal performs blind detection. A set of CCEs corresponds to one or more search spaces.

[0017] The PDCCH candidate is a candidate position of the PDCCH that occupies some CCEs in the search space. The terminal device searches the space by blind detection, decodes the PDCCH candidate, and receives the PDCCH.

[0018] Aggregation Level (AL) is an attribute of the search space. The aggregation level is the number of CCEs that constitute one PDCCH. In the protocol standard, various aggregation levels are defined, such as 1, 2, 4, 8, 16, etc. That is, one PDCCH can be formed by aggregating 1, 2, 4, 8, 16, etc. consecutive CCEs.

[0019] In the related technology, the terminal device needs to decode possible PDCCHs in the search space, i.e., blindly detect the PDCCHs. When multiple TRPs transmit one DCI signaling, if the terminal device has no restrictions on the control resource sets and search space resources of the multiple TRPs, the number of CCEs that the terminal device needs to detect exceeds the number of CCEs that the terminal device can support, and the number of blind detections that the terminal device performs to detect the PDCCH also exceeds the maximum number of blind detections.

[0020] FIG. 2 illustrates a block diagram of a communication system provided by an exemplary embodiment of the present disclosure, which may include an access network 12 and a terminal device 14 .

[0021] The access network 12 includes several network devices 120. A network device may be a base station, which is a device disposed in an access network to provide wireless communication functions for terminal devices. The base station may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of a device having a base station function may be different, for example, in an LTE system, it is called eNodeB or eNB, and in a 5G NR system, it is called gNodeB or gNB. As communication technology develops, the description of "base station" may change. To facilitate the description of the embodiments of the present disclosure, devices providing wireless communication functions for the terminal devices 14 are collectively referred to as network devices.

[0022] The terminal equipment 14 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or Internet of Things (IoT) devices, or Industry Internet of Things (IIoT) devices, or other processing devices connected to a wireless modem, as well as various forms of user devices, mobile stations (MS), terminal devices, etc. For ease of explanation, the above-mentioned devices are collectively referred to as terminal equipment. The network device 120 and the terminal equipment 14 communicate with each other through a specific air interface technology such as the Uu interface.

[0023] The technical solutions of the embodiments of the present disclosure include a Global System of Mobile Communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an Advanced Long Term Evolution (LTE-A) system, a New Radio (NR) system, an evolution system of the NR system, an LTE-based access to Unlicensed spectrum (LTE-U) system, an NR-U system, a Universal Mobile Telecommunication System (UMTS), a Worldwide Interoperability for Microwave Access (WIM) system, a LTE-based access to Unlicensed spectrum (LTE-U) system, a NR-U system, a Universal Mobile Telecommunication System (UMTS), a LTE-based access to Unlicensed spectrum (LTE-U) system, a NR-U system, a NR-based access to Unlicensed spectrum (NR-U) ... The present invention may be applied to various communication systems such as WiMAX (Wireless Access) communication systems, Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next generation communication systems, or other communication systems.

[0024] Generally, the number of connections supported by conventional communication systems is limited and easily realized, but with the development of communication technology, mobile communication systems support not only conventional communication but also, for example, device to device (D2D) communication, machine to machine (M2M) communication, machine type communication (MTC), vehicle to vehicle (V2V) communication, and vehicle to everything (V2X) systems, etc. The embodiments of the present application can also be applied to these communication systems. 3 shows a flowchart of a receiving method provided by an exemplary embodiment of the present disclosure, which can be applied to the terminal device shown in FIG 2. The method includes the following steps 310-320.

[0025] Step 310: determining resource mapping relationships among the CCE sets of the N beam directions.

[0026] N is a positive integer greater than 1.

[0027] The terminal equipment and the network device use beam transmission and reception in which there are N different beam directions. There is a resource mapping relationship between the CCE sets of the N beam directions. A CCE set is a set including a set of CCEs, and the embodiment of the present disclosure does not limit the number of CCEs in a CCE set.

[0028] Optionally, the resource mapping relationship includes at least one of a frequency domain mapping relationship and a time domain mapping relationship. The terminal device determines a frequency domain mapping relationship and / or a time domain mapping relationship between the CCE sets of the N beam directions.

[0029] In the embodiment of the present disclosure, N beam directions may correspond one-to-one with N different TRPs, or one of the beam directions may correspond to two or more TRPs, or two or more of the beam directions may correspond to one TRP. Optionally, multiple TRPs may belong to the serving cell or neighboring cells of the terminal device. Hereinafter, only N beam directions correspond one-to-one with N different TRPs for illustrative purposes.

[0030] Step 320, receive DCI signaling transmitted on the CCE set of the N beam directions based on the resource mapping relationship.

[0031] Here, the DCI signaling is the payload carried on a set of CCEs in N beam directions.

[0032] When a network device transmits DCI signaling in N beam directions, a terminal device determines a resource mapping relationship between the CCE sets of the N beam directions, and receives the DCI signaling based on the resource mapping relationship.

[0033] As described above, in the method provided by this embodiment, when a network device transmits one DCI signaling in N beam directions (which can correspond to multiple TRPs), the terminal equipment can determine a resource mapping relationship between the CCE sets of the N beam directions and receive the DCI signaling based on the resource mapping relationship, and since the resource mapping relationship exists, the number of PDCCH blind detections of the terminal equipment can be reduced.

[0034] In an alternative embodiment of Fig. 3, Fig. 4 shows a flowchart of a receiving method provided by an exemplary embodiment of the present disclosure, which can be applied to the terminal device shown in Fig. 2. In this embodiment, instead of step 310, step 311 or step 312 is implemented.

[0035] Step 311: determining resource mapping relationships among the CCE sets of the N beam directions according to an instruction from a network device.

[0036] The resource mapping relationship is instructed to the terminal device by the network device. Based on the instruction of the terminal device network device, the resource mapping relationship between the CCE sets of the N beam directions is determined.

[0037] Step 312: determine a predefined resource mapping relationship as the resource mapping relationship between the CCE sets of the N beam directions.

[0038] The resource mapping relationship is predefined, written into a standard protocol, and stored in a chip of the terminal device. The resource mapping relationship can be understood as a default mapping relationship, and the terminal device determines the resource mapping relationship between the CCE sets of the N beam directions based on the stored default mapping relationship.

[0039] Step 320, receive DCI signaling transmitted on the CCE set of the N beam directions based on the resource mapping relationship.

[0040] The CCE sets for N beam directions include the i-th CCE set for the i-th beam direction, where i takes a value from 1 to N and N is a positive integer greater than 1.

[0041] Alternatively, the CCE sets of the N beam directions each transmit a complete content of the DCI signaling, i.e., the i-th CCE set transmits the complete content of the DCI signaling, or the CCE sets of the N beam directions jointly transmit the complete content of the DCI signaling, i.e., the i-th CCE set transmits a partial content of the DCI signaling, and the content transmitted by the N CCE sets is a complete content of one DCI signaling together.

[0042] Optionally, each CCE set includes one PDCCH candidate, which is a candidate position for a PDCCH that occupies some CCEs.

[0043] Alternatively, the CCE sets of different beam directions belong to the same search space, or the CCE sets of different beam directions belong to different search spaces of the same control resource set, or the CCE sets of different beam directions belong to different control resource sets.

[0044] Illustratively, referring to FIG. 1, control resource set #1 includes three different search spaces: search space #1, search space #2, and search space #3. CCE sets with different beam directions can all belong to search space #1 (i.e., the same search space), or can belong to search space #1, search space #2, and search space #3 (i.e., different search spaces), respectively, and some belong to control resource set #1, while others belong to control resource set #2 (i.e., different control resource set), not shown.

[0045] Alternatively, the CCE set includes X CCEs, where X is a positive integer, and X is equal to the aggregation level of the DCI signaling, or X is equal to the aggregation level of the DCI signaling divided by N.

[0046] Here, the aggregation level is a property of the search space. The aggregation level is the number of CCEs that constitute one PDCCH, and the PDCCH is used to transmit the DCI signaling. The aggregation levels include, but are not limited to, 1, 2, 4, 8, and 16.

[0047] Illustratively, when the aggregation level of DCI signaling is four and the number of beam directions N is two, the number of CCEs X included in the CCE set is four or two.

[0048] Illustratively, when the aggregation level of the DCI signaling is 8 and the number of beam directions N is 2, the number of CCEs X included in the CCE set is 8 or 4.

[0049] The embodiments of the present disclosure exemplarily illustrate that the CCE sets for the N beam directions all include the same number of X CCEs, and the CCE sets for the N beam directions may include different numbers of CCEs, but the embodiments of the present disclosure are not limited to this.

[0050] As described above, the method provided by this embodiment is such that, when a network device transmits one DCI signaling in N beam directions (which can correspond to multiple TRPs), the terminal equipment can determine a resource mapping relationship between the CCE sets of the N beam directions and receive the DCI signaling based on the resource mapping relationship, and since the resource mapping relationship exists, the number of PDCCH blind detections of the terminal equipment can be reduced.

[0051] In the method provided by this embodiment, a terminal device determines a resource mapping relationship based on an instruction from a network device, or determines a resource mapping relationship based on pre-defined content of a standard protocol, thereby enhancing the flexibility of the terminal device in determining the resource mapping relationship.

[0052] In an optional embodiment of FIG. 3, the resource mapping relationship includes at least one of a frequency domain mapping relationship and a time domain mapping relationship.

[0053] If the resource mapping relationship includes a frequency domain mapping relationship, the N beam directions may correspond to the same frequency domain resource or different frequency domain resources.If the resource mapping relationship includes a time domain mapping relationship, the N beam directions may correspond to the same time domain resource or different time domain resources.

[0054] The present invention will now be described by way of example in conjunction with the following examples.

[0055] First, the resource mapping relationship includes a frequency domain mapping relationship.

[0056] 1) The N beam directions correspond to the same frequency domain resource, and the N beam directions correspond to the same first set of CCEs in the frequency domain.

[0057] The terminal device may receive DCI signaling in any of the following ways:

[0058] Realization form 1: When the complete content of DCI signaling is transmitted via the same frequency domain resources in N beam directions, respectively, the terminal device receives the same DCI signaling transmitted in the first CCE set in each of the N beam directions.

[0059] When one complete DCI signaling is transmitted using the same frequency domain resource for each of N beam directions, the CCE sets for the N beam directions are at the same position in the frequency domain and can be denoted as a first CCE set. It can be understood that the first CCE set has the same frequency domain position and may have the same or different time domain positions for different beam directions.

[0060] Realization form 2: When jointly transmitting complete content of DCI signaling via the same frequency domain resources in N beam directions, a terminal device receives DCI signaling based on first instruction information, where the first instruction information indicates a position order in the DCI signaling of content transmitted on CCEs in a first CCE set corresponding to each beam direction.

[0061] When transmitting parts of DCI signaling using the same frequency domain resources in N beam directions, thereby jointly transmitting the complete content of one DCI signaling, it is necessary to indicate the location in the DCI signaling of the content transmitted by CCEs in different beam directions.

[0062] Illustratively, there are two TRPs, TRP#0 and TRP#1, and the two TRPs correspond to two different beam directions, and the first CCE set includes two CCEs, CCE#0 and CCE#1. The CCEs in the first CCE set corresponding to each beam direction can be written as TRP#0CCE#0, TRP#0CCE#1, TRP#1CCE#0, and TRP#1CCE#1. The same CCE corresponds to different TRPs, and actually receives information transmitted by the same CCE in different TRPs using different beam directions. The network device needs to indicate the order of the contents of the DCI signaling transmitted by these four CCEs to the terminal device so that the terminal device can correctly decode the DCI signaling, and the position order of the four CCEs in the DCI signaling may be as follows:

[0063] Order 1: TRP#0CCE#0, TRP#0CCE#1, TRP#1CCE#0, TRP#1CCE#1.

[0064] Order 2: TRP#0CCE#0, TRP#1CCE#0, TRP#0CCE#1, TRP#1CCE#1.

[0065] There may be other orders for the four CCEs, and embodiments of the present disclosure are not limited thereto.

[0066] 2) The N beam directions correspond to different frequency domain resources, and the N beam directions have a one-to-one correspondence with the N CCE sets.

[0067] The terminal device may receive DCI signaling in any of the following ways:

[0068] Realization form 1: When the complete content of DCI signaling is transmitted respectively through different frequency domain resources in N beam directions, the terminal equipment receives the same DCI signaling transmitted in N beam directions and N CCE sets respectively based on second indication information, and the second indication information is used to indicate the mapping relationship between the numbers of specific CCEs in the N CCE sets.

[0069] When transmitting one complete DCI signaling using different frequency domain resources in N beam directions, respectively, the terminal equipment needs to determine the frequency domain position relationship between the CCEs in the N CCE sets, and the frequency domain position relationship between the CCEs in the N CCE sets can be indicated by a mapping relationship between the numbers of specific CCEs in the N CCE sets.

[0070] The specific CCE is one designated CCE in the CCE set. Optionally, the specific CCE is a CCE with the lowest frequency in the CCE set. Optionally, the mapping relationship between the numbers of the specific CCE is set based on different aggregation levels, or the mapping relationship between the numbers of the specific CCE is the same for all aggregation levels.

[0071] Illustratively, there are two TRPs, TRP#0 and TRP#1, and the two TRPs correspond to two different beam directions, TRP#0 corresponds to CCE set 1 and TRP#1 corresponds to CCE set 2, CCE set 1 includes {CCE#i, CCE#i+1}, and CCE set 2 includes {CCE#j, CCE#j+1}.

[0072] When the terminal device detects that CCE#i and CCE#i+1 transmit DCI signaling to itself through TRP#0, it knows that the DCI signaling transmitted by TRP#1 through CCE#j and CCE#j+1 is the same DCI signaling based on the mapping relationship. The relationship between CCE#i and CCE#j may be j=i+offset. The offset may be 0, i.e., the numbers are the same. The offset may be greater than 0, and if i+offset is greater than the maximum number of CCEs in TRP#1, j is the remainder of the value of (i+offset) / (maximum number of CCEs in TRP#1+1).

[0073] In addition, the frequency domain resource positions of the control resource sets of TRP#0 and TRP#1 may be different, and since the CCE numbers are numbers within each control resource set, the fact that the CCE numbers are the same does not mean that the frequency domain resources are the same.

[0074] Realization form 2: When the complete content of DCI signaling is transmitted through different frequency domain resources in N beam directions, respectively, the terminal device receives the same DCI signaling transmitted in N beam directions and N CCE sets, respectively, based on third instruction information, and the third instruction information indicates a mapping relationship between the numbers of PDCCH candidates corresponding to each of the N CCE sets.

[0075] When transmitting one complete DCI signaling using different frequency domain resources in N beam directions, the terminal device needs to determine the frequency domain position relationship between the CCEs in the N CCE sets, and the frequency domain position relationship between the CCEs in the N CCE sets can be indicated by a mapping relationship between the numbers of the PDCCH candidates corresponding to each of the N CCE sets.

[0076] Alternatively, the mapping relationship between the numbers of the PDCCH candidates is set based on different aggregation levels, or the mapping relationship between the numbers of the PDCCH candidates is the same for all aggregation levels.

[0077] Exemplarily, when different control resource sets are used for N beam directions, for each aggregation level, the CCE numbers included in the PDCCH candidate with the same number may be the same or different in different control resource sets. For example, when the aggregation level is 4, in CORESET#0, PDCCH candidate#0 occupies CCE#0-3, PDCCH candidate#1 occupies CCE#8-11, and PDCCH candidate#2 occupies CCE#16-19. In CORESET#1, PDCCH candidate#0 occupies CCE#16-19, PDCCH candidate#1 occupies CCE#24-27, and PDCCH candidate#3 occupies CCE#0-3. The third indication information may indicate that PDCCH candidate#i of CORESET#0 corresponds to PDCCH candidate#i+offset of CORESET#1, where offset is an integer equal to or greater than 0. When a terminal device detects that PDCCH candidate#0 in CORESET#0 transmits DCI signaling to itself, it knows based on the mapping relationship that the DCI signaling transmitted by PDCCH candidate#i+offset in CORESET#1 is the same DCI signaling.

[0078] Realization form 3: When jointly transmitting the complete content of DCI signaling via different frequency domain resources in N beam directions, the terminal device receives DCI signaling based on fourth indication information, where the fourth indication information indicates a mapping relationship between numbers of specific CCEs in the N CCE sets.

[0079] When parts of DCI signaling are transmitted using different frequency domain resources in N beam directions, respectively, thereby jointly transmitting the complete content of one DCI signaling, the terminal device needs to determine the frequency domain positional relationship between CCEs in the N CCE sets, and the frequency domain positional relationship between CCEs in the N CCE sets can be indicated by the mapping relationship between the numbers of specific CCEs in the N CCE sets. At the same time, the terminal device can determine the positional order in the DCI signaling of the content transmitted by CCEs in different beam directions based on the default order. The default order is that the corresponding CCE content with the higher Transmission Configuration Indication (TCI) number is higher.

[0080] The specific CCE is one designated CCE in the CCE set. Optionally, the specific CCE is the lowest frequency CCE in the CCE set. Optionally, the mapping relationship between the numbers of the specific CCE is set based on different aggregation levels, or the mapping relationship between the numbers of the specific CCE is the same for all aggregation levels.

[0081] Realization form 4: When jointly transmitting complete content of DCI signaling via different frequency domain resources in N beam directions, the terminal device receives DCI signaling based on fifth instruction information, where the fifth instruction information indicates a mapping relationship between numbers of specific CCEs in the N CCE sets and a position order in the DCI signaling of the content transmitted on the CCEs in the N CCE sets.

[0082] When parts of DCI signaling are respectively transmitted using different frequency domain resources in N beam directions, thereby jointly transmitting complete content of one DCI signaling, the terminal device needs to determine a frequency domain position relationship between CCEs in the N CCE sets, and the frequency domain position relationship between CCEs in the N CCE sets can be indicated by a mapping relationship between specific CCE numbers in the N CCE sets. At the same time, the terminal device can determine a position order in the DCI signaling of content transmitted by CCEs in different beam directions using the fifth indication information.

[0083] The specific CCE is one designated CCE in the CCE set. Optionally, the specific CCE is the lowest frequency CCE in the CCE set. Optionally, the mapping relationship between the numbers of the specific CCE is set based on different aggregation levels, or the mapping relationship between the numbers of the specific CCE is the same for all aggregation levels.

[0084] Implementation form 5: When jointly transmitting the complete content of DCI signaling through different frequency domain resources in N beam directions, the terminal device receives DCI signaling based on sixth indication information, where the sixth indication information indicates a mapping relationship between the numbers of PDCCH candidates corresponding to each of the N CCE sets.

[0085] When parts of DCI signaling are transmitted using different frequency domain resources in N beam directions, respectively, thereby jointly transmitting the complete content of one DCI signaling, the terminal device needs to determine the frequency domain positional relationship between CCEs in N CCE sets, and the frequency domain positional relationship between CCEs in N CCE sets can be indicated by the mapping relationship between the numbers of PDCCH candidates corresponding to each of the N CCE sets. At the same time, the terminal device can determine the positional order in the DCI signaling of the content transmitted by CCEs in different beam directions based on the default order. The default order may be such that the corresponding CCE content with the higher TCI number is higher.

[0086] Alternatively, the mapping relationship between the numbers of the PDCCH candidates is set based on different aggregation levels, or the mapping relationship between the numbers of the PDCCH candidates is the same for all aggregation levels.

[0087] Realization form 6: When jointly transmitting complete content of DCI signaling through different frequency domain resources in N beam directions, the terminal device receives DCI signaling based on seventh instruction information, where the seventh instruction information indicates a mapping relationship between the numbers of PDCCH candidates corresponding to each of the N CCE sets and a position order in the DCI signaling of the content transmitted on the CCEs in the N CCE sets.

[0088] When parts of DCI signaling are transmitted using different frequency domain resources in N beam directions, respectively, thereby jointly transmitting the complete content of one DCI signaling, the terminal device needs to determine the frequency domain position relationship between CCEs in the N CCE sets, and the frequency domain position relationship between CCEs in the N CCE sets can be indicated by the mapping relationship between the numbers of PDCCH candidates corresponding to each of the N CCE sets. At the same time, the terminal device can determine the position order in the DCI signaling of the content transmitted by CCEs in different beam directions according to the seventh indication information.

[0089] Alternatively, the mapping relationship between the numbers of the PDCCH candidates is set based on different aggregation levels, or the mapping relationship between the numbers of the PDCCH candidates is the same for all aggregation levels.

[0090] Optionally, at least one of the second instruction information, the third instruction information, the fourth instruction information, the fifth instruction information, the sixth instruction information and the seventh instruction information of the above implementation further indicates a search space ID to which the N CCE sets belong and / or a control resource set ID to which the N CCE sets belong.

[0091] The search space ID identifies a different search space, and the control resource set indicates a different control resource set. When CCE sets of different beam directions belong to different search spaces of the same control resource set or different control resource sets, the terminal device can determine different search spaces of the same control resource set to which the N CCE sets belong and / or determine different control resource sets to which the N CCE sets belong based on the instruction.

[0092] Second, the resource mapping relationship includes a time domain mapping relationship.

[0093] 1) The N beam directions correspond to the same time-domain resource, and the N beam directions correspond to the same second set of CCEs in the time domain.

[0094] The terminal device may receive DCI signaling in any of the following ways:

[0095] Realization form 1: When the complete content of DCI signaling is transmitted via the same time domain resource in each of N beam directions, the terminal device receives the same DCI signaling transmitted in the second CCE set in each of N beam directions.

[0096] When one complete DCI signaling is transmitted using the same time domain resource in each of the N beam directions, the CCE sets in the N beam directions are at the same position in the time domain and can be described as a second CCE set. Note that the second CCE set has the same time domain position for different beam directions, and may be at the same or different frequency domain positions.

[0097] Realization form 2: When jointly transmitting complete content of DCI signaling via the same time domain resource in N beam directions, the terminal device receives DCI signaling based on eighth instruction information, where the eighth instruction information indicates the position order in the DCI signaling of the content transmitted on CCEs in the second CCE set corresponding to each beam direction.

[0098] When transmitting parts of DCI signaling using the same time domain resources in N beam directions, thereby jointly transmitting the complete content of one DCI signaling, it is necessary to indicate the location in the DCI signaling of the content transmitted by CCEs in different beam directions.

[0099] Illustratively, there are two TRPs, TRP#0 and TRP#1, and the two TRPs correspond to two different beam directions, and the second CCE set includes two CCEs, CCE#0 and CCE#1. The CCEs in the second CCE set corresponding to each beam direction can be written as TRP#0CCE#0, TRP#0CCE#1, TRP#1CCE#0, and TRP#1CCE#1. The same CCE corresponds to different TRPs, and actually receives information transmitted by the same CCE in different TRPs using different beam directions. The network device needs to indicate to the terminal device the order of the contents of the DCI signaling transmitted by these four CCEs so that the terminal device can correctly decode the DCI signaling, and the position order of the four CCEs in the DCI signaling may be as follows:

[0100] Order 1: TRP#0CCE#0, TRP#0CCE#1, TRP#1CCE#0, TRP#1CCE#1.

[0101] Order 2: TRP#0CCE#0, TRP#1CCE#0, TRP#0CCE#1, TRP#1CCE#1.

[0102] There may be other orders for the four CCEs, and embodiments of the present disclosure are not limited thereto.

[0103] 2) The N beam directions correspond to different time domain resources, and the N beam directions have a one-to-one correspondence with the N CCE sets.

[0104] The terminal device may receive DCI signaling in any of the following ways:

[0105] Realization form 1: When the complete content of DCI signaling is transmitted respectively in N beam directions via different time domain resources, the terminal equipment receives the same DCI signaling transmitted in N beam directions and N CCE sets respectively based on the ninth instruction information, and the ninth instruction information indicates the mapping relationship between the time domains of the N CCE sets.

[0106] When one complete DCI signaling is transmitted using different time domain resources in N beam directions, respectively, the terminal equipment needs to determine the time domain position relationship between the CCEs in the N CCE sets, and the time domain position relationship between the CCEs in the N CCE sets can be indicated based on the mapping relationship between the time domains of the N CCE sets.

[0107] Alternatively, the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between numbers of specific CCEs corresponding to each of the N CCE sets, or the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between numbers of PDCCH candidates corresponding to each of the N CCE sets. Optionally, the specific CCE is a CCE with the lowest frequency in the CCE set.

[0108] Alternatively, the mapping relationship between the time domains of the CCE sets is set based on different aggregation levels, or the mapping relationship between the time domains of the CCE sets is the same for all aggregation levels.

[0109] When the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between the numbers of specific CCEs corresponding to each of the N CCE sets, illustratively, there are two TRPs, TRP#0 and TRP#1, and the two TRPs correspond to two different beam directions, where TRP#0 corresponds to CCE set 1, TRP#1 corresponds to CCE set 2, CCE set 1 includes {CCE#i, CCE#i+1}, and CCE set 2 includes {CCE#j, CCE#j+1}. When the terminal device detects that CCE#i and CCE#i+1 transmit DCI signaling to itself in TRP#0, it knows that the DCI signaling transmitted by TRP#1 in CCE#j and CCE#j+1 is the same DCI signaling based on the mapping relationship. The relationship between CCE#i and CCE#j may be j=i+offset. The offset may be 0, that is, the numbers are the same. The offset may be greater than 0, and if i+offset is greater than the maximum CCE number of TRP#1, j takes the remainder as the value of (i+offset) / (maximum CCE number of TRP#1 + 1).

[0110] When the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between the numbers of the PDCCH candidates corresponding to each of the N CCE sets, exemplarily, the aggregation level is 4, and in CORESET#0, PDCCH candidate#0 occupies CCE#0-3, PDCCH candidate#1 occupies CCE#8-11, and PDCCH candidate#2 occupies CCE#16-19. In CORESET#1, PDCCH candidate#0 occupies CCE#16-19, PDCCH candidate#1 occupies CCE#24-27, and PDCCH candidate#3 occupies CCE#0-3. The ninth indication information can indicate that PDCCH candidate#i of CORESET#0 corresponds to PDCCH candidate#i+offset of CORESET#1, where offset is an integer equal to or greater than 0. When the terminal device detects that PDCCH candidate#0 transmits DCI signaling to itself in CORESET#0, it knows based on the mapping relationship that the DCI signaling transmitted by TRP#1 via PDCCH candidate#i+offset in CORESET#1 is the same DCI signaling. Realization form 2: When the complete content of DCI signaling is jointly transmitted using different time domain resources in N beam directions, the terminal device receives DCI signaling based on the tenth instruction information, and the tenth instruction information indicates the mapping relationship between the time domains of the N CCE sets.

[0111] When parts of DCI signaling are respectively transmitted using different time domain resources in N beam directions, thereby jointly transmitting the complete content of one DCI signaling, the terminal device needs to determine the time domain positional relationship between CCEs in the N CCE sets, and the time domain positional relationship between CCEs in the N CCE sets can be indicated based on the mapping relationship between the time domains of the N CCE sets. At the same time, the terminal device can determine the positional order in the DCI signaling of the content transmitted by CCEs in different beam directions based on a default order. The default order may be such that the corresponding CCE content with a higher TCI number is at the top.

[0112] Alternatively, the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between numbers of specific CCEs corresponding to each of the N CCE sets, or the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between numbers of PDCCH candidates corresponding to each of the N CCE sets. Optionally, the specific CCE is a CCE with the lowest frequency in the CCE set.

[0113] Alternatively, the mapping relationship between the time domains of the CCE sets is set based on different aggregation levels, or the mapping relationship between the time domains of the CCE sets is the same for all aggregation levels.

[0114] Realization form 3: When jointly transmitting complete content of DCI signaling using different time domain resources in N beam directions, the terminal device receives DCI signaling based on 11th instruction information, where the 11th instruction information indicates the mapping relationship between the time domains of the N CCE sets and the position order in the DCI signaling of the content transmitted on the CCEs in the N CCE sets.

[0115] When parts of DCI signaling are respectively transmitted using different time domain resources in N beam directions, thereby jointly transmitting complete content of one DCI signaling, the terminal device needs to determine the time domain position relationship between CCEs in the N CCE sets, and the time domain position relationship between CCEs in the N CCE sets can be indicated based on the time domain mapping relationship between the N CCE sets. At the same time, the terminal device can determine the position order in the DCI signaling of the content transmitted by CCEs in different beam directions using the eleventh indication information.

[0116] Alternatively, the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between numbers of specific CCEs corresponding to each of the N CCE sets, or the mapping relationship between the time domains of the N CCE sets includes a mapping relationship between numbers of PDCCH candidates corresponding to each of the N CCE sets. Optionally, the specific CCE is a CCE with the lowest frequency in the CCE set.

[0117] Alternatively, the mapping relationship between the time domains of the CCE sets is set based on different aggregation levels, or the mapping relationship between the time domains of the CCE sets is the same for all aggregation levels.

[0118] Optionally, at least one of the ninth instruction information, the tenth instruction information, and the eleventh instruction information of the above implementation further indicates a search space ID to which the N CCE sets belong and / or a control resource set ID to which the N CCE sets belong.

[0119] Here, the search space ID identifies a different search space, and the control resource set indicates a different control resource set. When CCE sets of different beam directions belong to different search spaces of the same control resource set or different control resource sets, the terminal device can determine different search spaces of the same control resource set to which the N CCE sets belong and / or determine different control resource sets to which the N CCE sets belong based on the instruction.

[0120] It should be noted that the above method embodiments may be implemented individually or in combination, and the present disclosure is not limited thereto.

[0121] In each of the above embodiments, the steps performed by the terminal device may be implemented individually as a receiving method on the terminal device side, and the steps performed by the network device may be implemented individually as a receiving method on the network device side.
