Description

[0001] This application is a divisional application of the Chinese patent application with application number "201810160248.2", application date "February 26, 2018", and title "Method and device for sending, receiving and determining information of control signaling". Technical Field

[0002] The present invention relates to the field of communications, and in particular to a method and device for sending and receiving control signaling and determining information. Background Art

[0003] As one of the core technologies of 5G, high-frequency communication provides strong support for the high-speed and large-bandwidth communications of the future. However, a core problem of high-frequency communication is the relatively large path loss. Considering the relatively small size of the antenna, multiple antennas can be used to form a beam to resist the path loss.

[0004] In order to improve system efficiency, resist beam blocking scenarios, and quickly recover links, the beam of the downlink signal can be notified through physical layer dynamic control signaling. When the interval between the control signaling and the downlink signal is less than a predetermined threshold, the terminal cannot obtain the receiving beam of the downlink signal through the information notified by the physical layer dynamic control signaling.

[0005] In the existing NR protocol, when the interval between the physical layer dynamic control signaling and the downlink signal is less than a predetermined threshold, the beam of the CORESET with the lowest CORESETID in the most recent slot is used to cache data.

[0006] The above scheme will have the following two problems. The first problem is that when the interval between the physical layer dynamic control signaling and the downlink signal is less than the predetermined threshold, the bit field of the notification beam in the physical layer dynamic control signaling is not fully utilized. The second problem is that before the physical layer dynamic control signaling is decoded, the downlink signal needs to be cached, but the actual downlink signal may not be scheduled by the base station. However, if the terminal needs to cache the potential downlink signal dynamically scheduled according to the CORESET of the most recent CORESETID according to regulations, there may still be previously scheduled signals at the location of these potential downlink signals. When the previously scheduled downlink signal and the beam terminal of the potential downlink signal cannot be simultaneously emitted, the base station and the terminal need to agree on the behavior to ensure the effectiveness of the communication.

[0007] With respect to the above technical problems, no effective solutions have been proposed in the relevant technologies. Summary of the invention

[0075] The present embodiment is described below with reference to optional embodiments.

[0076] Optional embodiment 1

[0077] In beam-based communication, the beam of the physical shared channel (PDSCH) can be notified through downlink control information (DCI). When the interval between DCI and PDSCH is less than K, the terminal needs to receive the PDSCH in the RF buffer before decoding the DCI. Therefore, NR now stipulates that when the interval between DCI and PDSCH is less than a predetermined threshold K, the QCL parameters of the DMRS of the PDSCH are obtained according to the QCL parameters corresponding to the lowest CORESETID in the most recent slot. When the interval between DCI and PDSCH is greater than or equal to the predetermined threshold K, the QCL information indicated in the DCI is used to obtain the QCL parameters of the DMRS of the PDSCH. However, in order to reduce the complexity of the terminal's blind detection of PDCCH, the load of the PDCCH when the interval between DCI and PDSCH is less than K is the same as the load of the PDCCH when the interval between DCI and PDSCH is greater than or equal to K. In this way, when the interval between DCI and PDSCH is less than K, the 3-bit TCI notification field in DCI (TCI notification field is used to notify the QCL parameters of DMRS of PDSCH) exists, but is not used. In the current NR version, the TCI notification field occupies 3 bits. Therefore, the following enhancement scheme is proposed.

[0078] When the interval between DCI and PDSCH is less than K, the 3-bit TCI notification field in DCI can notify one or more transmission parameters (i.e., the first transmission parameters) in DCI except the TCI transmission parameters. Now the transmission parameters in NR DCI format1_1 are in the order shown in Table 1. As can be seen from Table 1, the interval between DCI and PDSCH can be determined by the information indicated in the transmission parameter indication field 5.

[0079] Table 1

[0080]

[0081]

[0082] For example, the first transmission parameter is the transmission parameter numbered 14 in Table 1. When the interval between DCI and PDSCH is less than K, the resource indication field of PUCCH can use the bit field numbered 14 and the bit field numbered 17 in Table 1, a total of 5 bits, to indicate that one of the PUCCH resources is selected from at most 32 PUCCH resources. When the interval between DCI and PDSCH is greater than or equal to K, the resource of PUCCH only uses the indication field numbered 14 in Table 1 to indicate that one of the PUCCH resources is selected from at most 4 PUCCH resources. When the interval between DCI and PDSCH is less than K, the order of the indication fields in DCI can continue to follow the order of Table 1, except that indication field 14 and indication field 17 together constitute the PUCCH resource indication field. Alternatively, the transmission parameter indication field order shown in Table 2 can also be used at this time. The change in Table 2 compared to Table 1 is that transmission parameter indication field 17 is cancelled, and the number of bits of transmission parameter indication field 14 becomes 5 bits.

[0083] Table 2

[0084]

[0085]

[0086] In this way, when the transmission interval between DCI and PDSCH is less than the preset K value, DCI can be dynamically selected from 32 PUCCH resources, as shown in Table 3; when the transmission interval between DCI and PDSCH is greater than or equal to the preset K value, DCI can only be dynamically selected from 4 PUCCH resources, as shown in Table 4.

[0087] Table 3

[0088]

[0089]

[0090] Table 4

[0091] PUCCH resource selection parameter indication value in DCI PUCCH Resources 0 PUCCH resource 1 1 PUCCH resource 2 2 PUCCH resource 3 3 PUCCH resource 4

[0092] In Table 3 and Table 4, the 4 PUCCH resources in Table 4 are the same as the first 4 PUCCH resources in Table 3, so when notifying, the base station only needs to notify 32 PUCCH resources. Of course, this embodiment does not exclude that the PUCCH resources in Table 3 and the PUCCH resources in Table 4 may be different. In this way, when notifying using high-layer signaling, the base station notifies the PUCCH resources in Table 3 and Table 4 respectively.

[0093] In this embodiment, the interval between the DCI and the PDSCH may be one of the following intervals:

[0094] The interval between the end time domain symbol of DCI and the start time domain symbol of PDSCH;

[0095] The interval between the starting time domain symbol of DCI and the starting time domain symbol of PDSCH;

[0096] The interval between the latest time domain symbol in the CORESET end symbol in the slot where the DCI is located and the start time domain symbol of the PDSCH;

[0097] The interval between the earliest time domain symbol of CORESET in the slot where DCI is located and the start time domain symbol of PDSCH;

[0098] The interval between the end time domain symbol of the DCI and the start time domain symbol of the PDSCH in each of the multiple slots it occupies;

[0099] The interval between the starting time domain symbol of the DCI and the starting time domain symbol of the PDSCH in each of the multiple slots it occupies.

[0100] The above is that when the interval between DCI and PDSCH is less than the predetermined threshold K, the indication field of TCI is used for PUCCH resource indication. Similarly, when the interval between DCI and PDSCH is less than the predetermined threshold, the indication field of TCI is used for rate mating indication field. Similarly, when configuring rate mating information, high-level signaling needs to configure two sets of ratemating parameters, such as one set of parameters for establishing a table similar to that described in Table 3, and another set of parameters for establishing the table described in Table 4, or one set of parameters is only all the entries in this set of parameters for establishing Table 3, and the agreed part of the entries (such as the first M entries, or the last M entries) are used for establishing Table 4, but at this time, the tables in Table 3 and Table 4 should be the correspondence between the index value and the rate mating information, and the number of states in Table 3 and Table 4 will also change. For example, the rate-match-PDSCH-resource-set configured by the high-level layer includes 2 resources. When the transmission interval between DCI and PDSCH is less than the predetermined threshold, refer to Table 5 to obtain the rate mating information. There are a total of 2 in Table 5. (1 +3) = 16 index values, which are jointly indicated by transmission parameter indication field 8 and transmission parameter indication field 17 in Table 1; when the interval transmission time interval between DCI and PDSCH is greater than or equal to the predetermined threshold, refer to Table 6 to obtain rate mating information, a total of 2 in Table 6 (1) =2 states, indicated by the transmission parameter indication field 8 in Table 1.

[0101] Table 5

[0102] Index value of rate mating information in DCI Rate mating information 0 High-level configuration rate mating information 1 1 High-level configuration rate mating information 2 2 High-level configuration rate mating information 3 3 High-level configuration rate mating information 4 ... ... 15 High-level configuration rate mating information 16

[0103] Table 6

[0104] PUCCH resource selection parameter indication value in DCI PUCCH Resources 0 High-level configuration rate mating information 1 1 High-level configuration rate mating information 2

[0105] Similarly, when the interval between DCI and PDSCH is less than the predetermined threshold K, the TCI indication field can be used for any one or more transmission parameters of the other 20 parameters in Table 1 except the TCI transmission parameters. For example, when the interval between DCI and PDSCH is less than the predetermined threshold K, the first bit of the 3 bits of the TCI indication field is used for notification of rate mating information, and the last 2 bits are used for notification of ZP-CSI-RS information. Or, when the interval between DCI and PDSCH is less than the predetermined threshold, the type of transmission parameter indicated by the TCI field, or the type of transmission parameter indicated by each bit of the TCI field, is determined by agreed rules or signaling information. For example, the base station signaling indicates that when the interval between DCI and PDSCH is less than the predetermined threshold K, the first bit of the TCI indication field is used for notification of rate mating information, and the last two bits of the TCI indication field are used for notification of ZP-CSI-RS information, or the base station signaling indicates that when the interval between DCI and PDSCH is less than the predetermined threshold K, all three bits of the TCI field are used for notification of rate mating information; or the base station notifies through signaling that when the interval between DCI and PDSCH is less than the predetermined threshold K, the first two bits of the TCI field are used for notification of PDSCH frequency domain resources, and the last bit of the TCI field is used for notification of ZP-CSI-RS information.

[0106] In the above embodiment, when the interval between DCI and PDSCH is less than K, the TCI indication field is used to indicate other types of transmission parameters in Table 1 except the TCI transmission parameters, and can also be used to indicate transmission parameter types not in Table 1, such as for indicating CSI information (wherein the CSI information is used to trigger non-periodic CSI-RS and / or non-periodic CSI reporting). In this way, when the interval between DCI and PDSCH is less than K, the TCI indication field in the DCI is used to indicate the CSI triggering information. When the interval between DCI and PDSCH is greater than K, the TCI indication field is used to indicate the TCI information. At this time, the CSI information cannot be indicated in the DCI.

[0107] Optional embodiment 2

[0108] In this embodiment, based on the relationship between the transmission interval of the physical layer dynamic control signaling and the first signal and a predetermined threshold, at least one of the following information is determined: the transmission parameter type indicated by the specific indication field of the physical layer dynamic control signaling, and whether the physical layer dynamic control signaling includes indication information indicating a specific transmission parameter type.

[0109] Further, when the relationship is relationship one, the specific indication field of the physical layer dynamic control signaling is used to indicate a first type of transmission parameter;

[0110] When the relationship is relationship 2, the specific indication field of the physical layer dynamic control signaling is used to indicate a second type of transmission parameter;

[0111] Further, when the relationship is relationship one, the physical layer dynamic control signaling includes indication information indicating a specific transmission parameter type;

[0112] When the relationship is relationship 2, the physical layer dynamic control signaling does not include indication information indicating a specific transmission parameter type;

[0113] Further, the first relationship is that the transmission interval between the physical layer dynamic control signaling and the first signal is less than a predetermined threshold, and the second relationship is that the transmission interval between the physical layer dynamic control signaling and the first signal is greater than or equal to the predetermined threshold; or

[0114] The first relationship is that the transmission interval between the physical layer dynamic control signaling and the first signal is less than or equal to a predetermined threshold, and the second relationship is that the transmission interval between the physical layer dynamic control signaling and the first signal is greater than a predetermined threshold.

[0115] Further, the transmission parameter may be a transmission parameter of the first signal, or a transmission parameter of the second signal.

[0116] Specifically, when the transmission time interval between DCI and PDSCH (the first signal) is less than the K value, the indication field in the DCI numbered 17 in Table 1 is used to indicate the rate mating indication information; when the transmission time interval between DCI and PDSCH is greater than or equal to the K value, the indication field in the DCI numbered 17 in Table 1 is used to indicate the TCI information.

[0117] Alternatively, when the transmission time interval between DCI and PDSCH (the first signal) is less than the K value, the indication field in the DCI numbered 17 in Table 1 is used to indicate the CSI request information, and when the transmission time interval between DCI and PDSCH is greater than or equal to the K value, the indication field in the DCI numbered 17 in Table 1 is used to indicate the TCI information (i.e., the QCL parameter information of the DMRS of the PDSCH). That is, when the interval between DCI and PDSCH is less than K, the DCI of DL-Grant includes the CSI request indication information, and when the interval between DCI and PDSCH is greater than or equal to K, the DCI of DL-Grant does not include the CSI request indication information.

[0118] Optional embodiment 3

[0119] In the above optional embodiment 1 and optional embodiment 2, the number of candidate parameter values ​​included in the value set of the first transmission parameter will change according to the first relationship, for example, when the interval between DCI and PDSCH is less than K, the value set of the first transmission parameter includes X1 values, and when the interval between DCI and PDSCH is greater than K, the value set of the first transmission parameter includes X2 values. Or when the interval between DCI and PDSCH is less than K, the corresponding mapping table between the index value referenced by the index value of the first transmission parameter indicated by the control signaling in the DCI and the first transmission value is Table 1 (for example, as shown in Table 3), and when the interval between DCI and PDSCH is greater than K, the corresponding mapping table between the index value referenced by the index value of the first transmission parameter indicated by the control signaling in the DCI and the first transmission value is Table 2 (for example, as shown in Table 4).

[0120] Furthermore, whether there is a TCI indication field in the DCI is also configured per CORESET (Control resource set). The DCI in CORESET1 does not have a TCI indication field, that is, the DCI in CORESET1 does not include the transmission parameter indication field numbered 17 in Table 1. The DCI in CORESET2 has a TCI indication field, that is, the DCI in CORESET2 includes the transmission parameter indication field numbered 17 in Table 1, and it is agreed that when the transmission interval between DCI and PDSCH is less than the agreed threshold (such as K), the TCI indication field in the DCI is used to indicate the rate mating information. Therefore, the index value and rate mating information indicated in the DCI transmitted in CORESET2 refer to Table 5 and Table 6. When the interval between DCI and PDSCH is less than the predetermined threshold, refer to Table 5. When the interval between DCI and PDSCH is greater than or equal to the predetermined threshold, refer to Table 6. The rate indicated in the DCI in CORESET1 The index value and rating information referenced by the mating information also refer to Table 6. Or the index value and rating information referenced by the rate mating information indicated in the DCI in CORESET1 also refer to a table different from Table 6, such as Table 6-2, that is, at this time, the rate mating information refers to Table 3. In this way, when the base station notifies the rate mating information through high-level signaling, it is necessary to notify the rate mating information for each table, or the high-level layer notifies the information of Table 6 and Table 5 through one signaling, and notifies the information of Table 6-2 through another signaling.

[0121] That is, when the transmission interval between DCI and PDSCH is less than K, the table referenced by the index information of the rate mating information indicated in DCI is Table 5. In other cases, the table referenced by the index information of the rate mating information indicated in DCI is Table 6.

[0122] In the above implementation, the number of tables referenced by the rate mating information indicated in the DCI is Y. Similarly, the number of tables referenced by other transmission parameter types indicated in the DCI is Y. Y is a number greater than 1, for example, in the above implementation, Y=2 or Y=3.

[0123] Optional Embodiment 4

[0124] In the above embodiment, the second information is determined according to the first information, wherein the second information includes at least one of the following information: the number of bits N used to notify the first transmission parameter in the control signaling, the corresponding mapping table between the index value referenced by the first transmission parameter information notified in the control signaling and the first transmission parameter value, the type of the first transmission parameter notified by the predetermined indication field in the control signaling, and the position information of the bits used to notify the first transmission parameter in the control signaling. The first information includes: the relationship between the transmission time interval between the control signaling and the first signal and the predetermined threshold.

[0125] In this embodiment, the first information also includes at least one of the following information 1 to information 10.

[0126] Information 1: information included in the second control signaling, such as signaling information sent by the base station to the terminal, in which at least one of the following information is notified: whether the TCI field can be used for notification of other transmission parameter types, the transmission parameter type that the TCI field can be used for notification, which bits of the TCI field can be used for the transmission parameter type that is notified, and the second information is determined according to the information notified in the second control signaling;

For example, when the TCI-PresentInDCI associated with CORESTE is not enabled, there is no TCI field in the DCI in this CORESET, and the number of bits used for the first transmission parameter will not change with whether the transmission time interval between DCI and PDSCH is less than the predetermined threshold K;

[0128] Information three: whether the carrier frequencies of the signal are less than a predetermined threshold K1, for example, when the PDSCH is below 6 GHz, the mechanism for determining the second information according to the first information will not be activated; or the processable frequency domain range sent by the terminal, when the frequency domain processing capability of the terminal is FR1 (that is, the processable frequency domain range of the terminal is less than the predetermined threshold, such as less than 6 GHz), the mechanism for determining the second information according to the first information will not be activated.

[0129] Information 4: whether there is at least one CORESET configured with the Spatial Rx parameter in the CORESET set that the first communication node needs to detect; for example, if there is no CORESET configured with the Spatial Rx parameter in the CORESET set that the terminal needs to detect, the mechanism for determining the second information according to the first information is not started;

[0130] Information 5: Whether there is at least one CORESET configured with the Spatial Rx parameter in the CORESET set associated with the dedicated Search space that needs to be detected by the first communication node; for example, if there is no CORESET configured with the Spatial Rx parameter in the CORESET set associated with the dedicated Searchspace that needs to be detected by the terminal, the mechanism for determining the second information according to the first information is not started;

[0131] Information six: whether the CORESET with the lowest CORESETID in the time unit closest to the signal is configured with the CORESET of the Spatial Rx parameter; for example, if the CORESET with the lowest CORESETID in the time unit closest to the PDSCH / AP-CSI-RS is not configured with the CORESET of the Spatial Rx parameter, the mechanism for determining the second information according to the first information is not started;

[0132] Information seven: whether the CORESET with the lowest CORESETID in the time domain symbol closest to the signal is configured with the CORESET of the Spatial Rx parameter; for example, if the CORESET with the lowest CORESETID in the time domain symbol closest to the PDSCH / AP-CSI-RS is not configured with the CORESET of the Spatial Rx parameter, the mechanism for determining the second information according to the first information is not started;

[0133] Information eight: whether there is at least one TCI state in the TCI state pool associated with the signal, and the QCL parameter corresponding to the reference RS set in the TCI state includes the Spatial Rx parameter; for example, in the TCI state pool of the RRC configuration associated with the PDSCH, there is no TCI state, and the QCL parameter corresponding to a DL-RS in the TCI state includes the Spatial Rx parameter, then the mechanism for determining the second information according to the first information is not started;

[0134] Information nine: whether there is at least one TCIstate in the activated TCI state pool associated with the signal, and the QCL parameter corresponding to the reference RS set in the TCI state includes the Spatial Rx parameter; for example, in the TCI state pool activated by the MAC-CE associated with the PDSCH or the TCI state pool consisting of the TCI state indicated by the TCI domain in the DCI, there is no TCI state, and the QCL parameter corresponding to a DL-RS in the TCI state includes the Spatial Rx parameter, then the mechanism for determining the second information according to the first information is not started;

[0135] Information 10: Frequency domain range processing capability information reported by the first communication node. For example, if the terminal reports that its processable frequency domain range is FR1 (that is, the processable frequency domain range is less than 6 GHz), the mechanism for determining the second information based on the first information will not be activated. When the terminal reports that its processable frequency domain range is FR2 (that is, the processable frequency domain range includes greater than or equal to 6 GHz), the mechanism for determining the second information based on the first information will be activated.

[0136] Optional embodiment 5

[0137] In this embodiment, the table referenced by the TCI field notified in the DCI is determined according to the relationship between the interval between the DCI and the PDSCH and the predetermined threshold K.

[0138] Specifically, when the interval between DCI and PDSCH is less than a predetermined threshold K, the table referenced by TCI in the DCI is Table 7; when the interval between DCI and PDSCH is greater than or equal to the predetermined threshold K, the table referenced by TCI in the DCI is Table 8. TCI state10 to TCI state17 and TCI state20 to TCI state27 are configured by different high-level control signaling, wherein the high-level control signaling includes RRC signaling and / or MAC-CE signaling.

[0139] Optionally, when the interval between DCI and PDSCH is less than K, the Spatial Rx parameter of the DMRS of PDSCH is obtained according to the agreed rules (for example, according to the configuration of the Spatial Rx parameter of the CORESET with the lowest CORESETID in the most recent slot), and other QCL parameter information of the DMRS of PDSCH is obtained through the TCI indication field in DCI and with reference to Table 7. Or all QCL parameters of PDSCH are obtained through the information indicated by the TC indication field in DCI and with reference to Table 7, but the configuration of Table 7 is limited. When the interval between DCI and PDSCH is greater than or equal to K, all QCL parameters of the DMRS of PDSCH are obtained according to the information indicated by the TCI indication field in DCI and with reference to Table 8.

[0140] Table 7

[0141] Index value of the TCI field in the DCI TCI state value 0 TCI state10 1 TCI state11 2 TCI state12 3 TCI state13 4 TCI state14 5 TCI state15 6 TCI state16 7 TCI state17

[0142] Table 8

[0143]

[0144]

[0145] One of the states is used to establish an association relationship between Q DMRS groups of PDSCHs and Q DL-RS sets, where Q is an integer greater than or equal to 1, as shown in Table 9. In a TCI state-n, an association is established between (DMRS group1, DL-RS set1) and (DMRS group2, DL-RS set2), where DL-RS set1 includes {DL-RS1, DL-RS2}, DL-RS set2 includes DL-RS3, where DMRS group1 has a QCL relationship with DL-RS1 regarding the QCL parameters in QCL-type1, where each QCL-Type includes at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, average gain, Spatial Rx parameter. The DL-RS (Down-link reference signal) can be CSI-RS / SSB / DMRS of PBCH, where the DMRS group can also be called QCL target reference signal, and the DL-RS can also be called QCL reference signal.

[0146] Table 9

[0147]

[0148] Furthermore, the DL-RS set composed of the QCL parameter Spatial Rx parameter included in the QCL-Type associated with each TCI state in Table 7 has predetermined constraints, wherein the constraints include at least one of the following: this DL-RS set includes only one DL-RS; the DL-RSs in this set are QCL with respect to the Spatial Rx parameter; the DL-RS terminals in this set can receive them simultaneously, this DL-RS set is an empty set, and the DL-RSs in this set belong to a group, which can be allocated by the base station or reported by the terminal. Specifically, for example, the DL-RSs including the Spatial Rx parameter in the QCL-Type associated with the 8 states in Table 7 include {DL-RS100, DL-RS101, DL-RS102, DL-RS103, DL-RS104, DL-RS105, DL-RS106, DL-RS107} (that is, the DMRS group and DL-RS10i in statei at least satisfy the QCL relationship with respect to the Spatial Rx parameter, i = 0, 1, ..., 7), the DL-RSs in this set are QCL with respect to the Spatial Rx parameter, or these DL-RSs can be received by the terminal at the same time, or the DL-RSs including the Spatial Rx parameter in the QCL-Type associated with the 8 states in Table 7 are all DL-R100, or the QCL-Type associated with these DL-RSs do not include the Spatial Rx parameter, and the Spatial Rx of the DMRS of the PDSCH at this time is agreed. The parameter is obtained according to the agreed rules. For example, it is agreed that the DMRS of PDSCH and the DMRS in the lowest CORESETID are QCL regarding the Spatial Rx parameter.

[0149] In this embodiment, when the interval between DCI and PDSCH is less than a predetermined threshold value K, the table referenced by the TCI indication field included in the DCI is Table 7, and when the interval between DCI and PDSCH is greater than or equal to the predetermined threshold value K, the table referenced by the TCI indication field in the DCI is Table 8. Because the configuration of the DL-RS associated with the Spatial Rx parameter in the TCI state in Table 7 is restricted, that is, there is only one or a limited number of beams associated with these TCI states. Because the terminal has not decoded the DCI at this time, it is required that the terminal knows the Spatial Rx parameter of the PDSCH before decoding the DCI, and there is no such restriction in Table 8, so two tables, Table 7 and Table 8, are required.

[0150] The configuration of Table 7 is configured by high-level signaling. In order to achieve the use of different beams at different times, even when the transmission time interval between DCI and PDSCH is less than K, multiple Tables 7 can be configured, and each Table 7 configures the time domain pattern in which it works, such as configuring the period and period offset of Table 7-1, and configuring the period and period offset of Table 7-2. Or there are two Tables 7, namely Table 7-1 and Table 7-2, configuring the period and period offset of Table 7-1, and referring to Table 7-2 in the remaining slots, that is, when the DCI falls in the slot shown in Table 7-1, the TCI domain notified in this DCI refers to Table 7-1, and when the DCI falls in the remaining slots, the TCI domain notified in the DCI refers to Table 7-2. It is also possible to configure three Tables 7, such as Table 7-1, Table 7-2, and Table 7-3, and configure the period and period offset of Table 7-1, and also configure the period and period offset shown in Table 7-2. Table 7-3 does not configure the period and period offset. When the DCI falls in the slot where Table 7-1 is located, the TCI indication field in the DCI refers to Table 7-1. When the DCI falls in the slot where Table 7-2 is located, the TCI indication field in the DCI refers to Table 7-2. When the DCI falls in other slots, the TCI indication field in the DCI refers to Table 7-3. In short, when the interval between DCI and PDSCH is less than the predetermined threshold, the QCL information of the PDSCH is obtained according to the TCI indication information indicated in the DCI and the table referenced by the corresponding TCI in the slot where the PDSCH is located. Figure 5As shown, the time domain pattern corresponding to Table 7-1 to Table 7-3 is configured. When the PDSCH falls in slotn and the interval between the PDSCH and the DCI is less than the predetermined threshold K, the QCL parameter of the DMRS of the PDSCH is obtained by referring to Table 7-1 according to the TCI information indicated in the DCI. When the PDSCH falls in slotn+1 and the interval between the PDSCH and the DCI is less than the predetermined threshold K, the QCL parameter of the DMRS of the PDSCH is obtained by referring to Table 7-2 according to the TCI information indicated in the DCI. When the PDSCH falls in slotn and the interval between the PDSCH and the DCI is greater than or equal to the predetermined threshold K, the QCL parameter of the DMRS of the PDSCH is obtained by referring to Table 8 according to the TCI information indicated in the DCI.

[0151] Similarly, based on the relationship between the interval between DCI and AP-CSI-RS and the predetermined threshold, a table corresponding to the TCI parameter of AP-CSI-RS is determined.

[0152] In an optional embodiment, the TCI indication information is used to indicate the QCL relationship between the DMRS group / CSI-RS port group and the DL-RS set, that is, one TCI index information corresponds to one state, one state includes the corresponding relationship between Q DMRS groups and Q DL-RS sets, one DL-RS set includes one or more DL-RSs, and each DL-RS is associated with a QCL parameter set, indicating that the reference signal in the DMRS group / CSI-RS port group and a DL-RS in the DL-RS set associated therewith satisfy a QCL (quasi-co-location) relationship with respect to the QCL parameter set. Two reference signals satisfy a quasi-co-location relationship with respect to one QCL parameter, indicating that the QCL parameter of one reference signal can be obtained by the QCL parameters of two reference signals, wherein the QCL parameter includes at least one of the following parameters:

[0153] Doppler shift, Doppler spread, average delay, delay spread, average gain, Spatial Rx parameter.

[0154] In this optional embodiment, the two reference signals are QCL, which means that the two reference signals are QCL at least with respect to the SpatialRx parameter, and there is no restriction on whether the two reference signals are QCL with respect to other QCL parameters.

[0155] In an optional embodiment, the channel may also be a signal, that is, a signal is transmitted on the channel, such as a data signal is transmitted on a data channel.

[0156] In an optional embodiment, different CCs (component carriers) may be associated via different ServingcellIDs.

[0157] In this embodiment, a method for receiving control signaling is also provided. Fig. 9 is a flow chart of a method for sending control signaling according to an embodiment of the present invention, such as Fig. 9 As shown, the process includes the following steps:

[0158] Step S902, determining second information according to the first information;

[0159] Step S904, receiving a first control signaling according to the second information;

[0160] Among them, the above-mentioned second information includes at least one of the following: the number of bits N used to notify the first transmission parameter in the first control signaling, the corresponding mapping table between the index value referenced by the first transmission parameter in the first control signaling and the value of the above-mentioned first transmission parameter, the type of the first transmission parameter notified by the predetermined indication field in the first control signaling, and the position information of the bits used to notify the first transmission parameter in the first control signaling; the above-mentioned first information includes: the relationship between the transmission time interval between the above-mentioned first control signaling and the first signal and the predetermined threshold K, N and K are non-negative integers.

[0161] Optionally, when the above relationship is the first relationship, the value of the above N includes N1; when the above relationship is the second relationship, the value of the above N includes N2; wherein N1 and N2 are integers.

[0162] Among them, the relationship between the above-mentioned N1 and the above-mentioned N2 satisfies at least one of the following: the above-mentioned N1 is greater than the above-mentioned N2; the difference between the above-mentioned N1 and the above-mentioned N2 is less than or equal to the number of bits occupied by the transmission configuration indication (Transmission configuration indication, referred to as TCI) field; the difference between the above-mentioned N1 and the above-mentioned N2 is less than or equal to the number of bits required to notify the second transmission parameter information.

[0163] Optionally, when the above relationship is a first relationship, the above corresponding mapping table is a first corresponding mapping table; when the above relationship is a second relationship, the above corresponding mapping table is a second corresponding mapping table;

[0164] Optionally, any one of the above-mentioned first corresponding mapping table, the above-mentioned second corresponding mapping table, transmission parameter value set one and transmission parameter value set two is determined by at least one of the following methods: method one, the content included in the sent signaling information; method two, the rules pre-agreed by the sending end and the receiving end; wherein, the above-mentioned transmission parameter value set one corresponds to the value set of the above-mentioned first transmission parameter included in the above-mentioned first corresponding mapping table, and the above-mentioned transmission parameter value set two corresponds to the value set of the above-mentioned first transmission parameter included in the above-mentioned second corresponding mapping table.

[0165] In an optional implementation, when the type of the first transmission parameter is TCI, the DL-RS set composed of the downlink reference signal (DL-RS) associated with the spatial Rx parameter in each state in the first corresponding mapping table includes only one DL-RS; when the first transmission parameter type is TCI, the DL-RSs in the DL-RS set composed of the downlink reference signal DL-RS associated with the spatial Rx parameter in each state in the first corresponding mapping table satisfy a quasi-co-location (QCL) relationship between each other regarding the spatial Rx parameter;

[0166] When the above-mentioned first transmission parameter type is TCI, the DL-RS in the DL-RS set composed of the downlink reference signal DL-RS of the associated spatial reception parameters in each state in the above-mentioned first corresponding mapping table can be simultaneously received by the first communication node; when the above-mentioned first transmission parameter type is TCI, the DL-RS set composed of the downlink reference signal DL-RS of the associated spatial reception parameters in each state in the above-mentioned first corresponding mapping table is an empty set; wherein the above-mentioned first communication node is a communication node that receives the above-mentioned first signal, and / or the above-mentioned first control signaling.

[0167] Optionally, the type of the first transmission parameter is one or more transmission parameter types included in the first control signaling except the TCI transmission parameter type; or, the first transmission parameter type is a TCI transmission parameter.

[0203] Optional Embodiment 6

[0204] In this embodiment, the base station and the terminal agree that multiple downlink signals on the same time domain symbol satisfy the QCL relationship, that is, the terminal does not want the multiple downlink signals configured by the base station in the same time domain symbol to not satisfy the QCL relationship, or the multiple downlink signals on the same time domain symbol to satisfy the QCL relationship between each other.

[0205] The multiple downlink signals include at least two of the following signals: PDSCH data signal, CORESET, downlink measurement reference signal, and downlink signals of multiple CCs. For example, the terminal does not want to receive downlink signals that do not meet the following configurations: multiple downlink signals do not meet the QCL relationship in one time domain symbol; or multiple downlink signals and the DMRS with the lowest CORESETID do not meet the QCL relationship in one time domain symbol.

[0206] like Figure 6a As shown, the DMRS of two PDSCHs belonging to different CCs (component carriers) that the terminal wishes to configure at the same time need to satisfy the QCL relationship. Figure 6b As shown, the terminal hopes that the PDSCH / DMRS on CC1 and the DMRS of the CORESET on CC2 configured at the same time must satisfy the QCL relationship. Figure 6c As shown, the terminal hopes that the DMRSs of two CORESETs belonging to different CCs configured at the same time need to satisfy the QCL relationship. Figure 6d As shown, the terminal hopes that the PDSCH / DMRS belonging to CC1 and the DMRS of the CORESET on CC2 configured at the same time need to satisfy the QCL relationship.

[0207] Figure 6a~6d In this case, multiple downlink signals belonging to different CCs need to satisfy the QCL relationship. Figures 7a to 7d In this case, multiple downlink signals belonging to the same CC need to satisfy the QCL relationship. Figure 7e The two CSI-RS in a CC need to satisfy the QCL relationship. Similarly, it is required that the CSI-RS from different CCs on the same time domain symbol are QCL at least with respect to the SpatialRx parameter.

[0208] Furthermore, the lowest CORESETID satisfies at least one of the following characteristics: the lowest CORESETID is the lowest CORESETID in the time domain symbol closest to the time domain symbol; the lowest CORESETID is the lowest CORESETID in the slot closest to the time domain symbol; the distance between the CORESET and the time domain symbol is less than a predetermined threshold K.

[0209] In this embodiment, different CCs may correspond to different Serving cellIDs.

[0210] Alternative Embodiment 7

[0211] In this optional embodiment, based on the relationship between the interval between the first signal and the specific CORESET and a predetermined threshold, at least one of the following information is determined: the QCL parameters of the first signal, the priority between the QCL parameters of the first signal and the second signal on the same time domain symbol, the priority between the QCL parameters of the first signal and the QCL parameters of the specific CORESET, and whether the first signal and the second signal can be frequency-division multiplexed on the same time domain symbol.

[0212] Furthermore, the specific CORESET satisfies at least one of the following characteristics: the CORESET is the CORESET with the lowest CORESETID in the time domain symbol closest to the downlink signal; the CORESET is the CORESET with the lowest CORESETID in the slot closest to the downlink signal; in the CORESET, the terminal needs to detect the DCI that schedules the downlink signal and / or channel; the CORESET does not include control signaling information for scheduling the first signal; the CORESET includes control signaling information for scheduling the second signal; the CORESET is associated with at least one dedicated search space (Search space).

[0213] Further, when the interval between the first signal and the CORESET is less than a predetermined threshold, the QCL parameters of the first signal are obtained according to the QCL parameters of the CORESER; when the interval between the downlink reference signal and the lowest CORESETID is greater than or equal to the predetermined threshold, the QCL parameters of the first signal are obtained through the QCL parameters configured in the downlink signal configuration information.

[0214] Further, when the interval between the first signal and the CORESET is less than a predetermined threshold, the QCL parameter priority of the first signal is higher than the QCL parameter of the second signal; when the interval between the first signal and the CORESET is greater than or equal to a predetermined threshold, the QCL parameter priority of the first signal is lower than the QCL parameter of the second signal.

[0215] Further, when the interval between the first signal and the CORESET is less than a predetermined threshold, the first signal and the second signal cannot be frequency-division multiplexed; when the interval between the first signal and the CORESET is greater than or equal to a predetermined threshold, the first signal and the second signal can be frequency-division multiplexed.

[0216] The QCL parameters include at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, average gain, and Spatial Rx parameter.

[0217] Furthermore, the first signal includes at least one of the following signals: a downlink measurement reference signal, a downlink synchronization signal, a downlink demodulation reference signal, a downlink data channel signal, and a downlink control channel signal.

[0218] Furthermore, the second signal includes at least one of the following signals: a downlink measurement reference signal, a downlink synchronization signal, a downlink demodulation reference signal, a downlink data channel signal, and a downlink control channel signal.

[0219] Further, the predetermined threshold is equal to a second predetermined threshold, wherein the QCL parameter of the second signal is determined according to a relationship between the control information for scheduling the second signal and the interval between the second signal and the second predetermined threshold.

[0220] Specifically, NR now stipulates that when the interval between DCI and PDSCH is less than the predetermined threshold K, the Spatial Rx parameter of the lowest CORESETID in the most recent slot is used to receive PDSCH, because when the terminal caches PDSCH, DCI has not been solved yet, and a known beam needs to be used to cache PDSCH. PDSCH can exist at any position in the K time window after DCI. At this time, the PDSCH terminal in the K time window after DCI needs to use the beam cache PDSCH in the lowest CORESETID, but PDSCH may not actually exist, but the terminal still needs to cache these PDSCHs. The problem is that if there is a periodic CSI-RS in this time window and the Spatial Rx parameter of the periodic CSI-RS is different from the Spatial Rx parameter of the PDSCH that the terminal needs to cache, it is necessary to determine the priority between the two. One way is that the base station and the terminal agree that the Spatial Rx parameter of the downlink signal and / or channel in this window shall be based on the Spatial Rx parameter of the CORESET with the lowest CORESETID, and other QCL parameters of the downlink signal and / or channel shall also be based on the lowest CORESETID, or other QCL parameters are obtained according to the configuration information of the downlink signal or channel, such as the QCL parameter configuration information in the configuration information of the periodic CSI-RS.

[0221] Method 2: The base station and the terminal agree that when the distance between the periodic CSI-RS and the CORESET with the lowest CORESETID in the most recent slot is less than a predetermined threshold K, the at least Spatial Rx parameter of the periodic CSI-RS is better than the Spatial Rx parameter of the PDSCH in the same time domain symbol. When the distance between the periodic CSI-RS and the CORESET with the lowest CORESETID in the most recent slot is greater than or equal to the predetermined threshold K, the Spatial Rx parameter of the PDSCH on the same time domain symbol is better than the Spatial Rx parameter of the CSI-RS in the same time domain symbol.

[0222] like Figure 2 As shown, the CORESET with the lowest CORESETID in the slot closest to the periodic CSI-RS on slotn is CORESET0 on slotn. When PDSCH and CSI-RS are on the same time domain symbol on slotn, CSI-RS and PDSCH are received with the beam of CSI-RS, that is, at this time, the Spatial Rx parameter of PDSCH has a lower priority than the Spatial Rx parameter of periodic CSI-RS. At this time, for symbols without periodic CSI-RS in slotn, one way is to use the Spatial Rx parameter of periodic CSI-RS for reception, thereby reducing the number of beam switching times of the terminal on slotn, or the terminal and the base station agree to use the beam with the lowest distance from PDSCH for reception on time domain symbols without CSI-RS in slotn, such as Figure 3 shown.

[0223] The lowest CORESETID in the slot closest to the periodic CSI-RS on slotn+2 is still CORESET0 in slotn (the terminal does not need to detect CORESET on slotn+1 and slotn+2). At this time, the distance between the periodic CSI-RS domain CORESET0 on slotn+2 is greater than the predetermined threshold. If the PDSCH and CSI-RS are on the same time domain symbol on slotn+2, the PDSCH beam is used to receive the PDSCH and CSI-RS, that is, the Spatial Rx parameter of the PDSCH has a higher priority than the Spatial Rx parameter of the periodic CSI-RS. Or when the receiving beams of the PDSCH and CSI-RS on the same time domain symbol conflict on slotn+2, the measurement of the CSI-RS is abandoned. Because when the terminal on slotn needs to cache the PDSCH scheduled by CORESET0, the DCI has not been decoded yet, and there may be no PDSCH. In this case, periodic CSI-RS is received first. The terminal on slotn+2 needs to cache the DCI corresponding to the PDSCH, and the terminal has already decoded it. At this time, the PDSCH is determined by the terminal to be scheduled by the base station.

[0231] Further, on the time domain symbol where the second signal is located, the second communication node does not detect a control channel on the first signal;

[0232] Furthermore, the Spatial Rx parameter of the second signal is different from the Spatial Rx parameter of the first signal, or the spatial filter corresponding to the Spatial Rx parameter of the second signal and the spatial filter corresponding to the Spatial Rx parameter of the first signal cannot be simultaneously output by the first communication node.

[0233] Further, the second signal and the first signal belong to different CCs;

[0234] Specifically, Figure 1a As shown, in slot n, the base station schedules PDSCH1 for the terminal, wherein the DCI of PDSCH1 is scheduled (this DCI is in Figure 1aThe distance between CORESET1 in slot n and PDSCH1 is greater than a predetermined threshold K, so that the terminal in slot n knows for sure that the base station in slot n has scheduled PDSCH1, so the QCL parameters of PDSCH1 can be obtained through the information indicated in the DCI that schedules PDSCH1. In slotn, the terminal still needs to continue to detect CORESET0 and / or CORESET2. The DCI in CORESET0 or CORESET2 may schedule PDSCH2 for the terminal. Preferably, PDSCH2 and PDSCH1 are in different CCs. Since the DCI of the scheduled PDSCH2 has not been decoded by the terminal when receiving the potential PDSCH2, according to regulations, the potential PDSCH2 needs to use the beam with the lowest CORESETID in all CCs in slotn to receive PDSCH2. For example, the beam of CORESET0 needs to be used to receive PDSCH2. When the receiving beam of PDSCH1 indicated dynamically (through the SpatialRx parameter information indicated in the DCI) is different from the beam of CORESET0, the priority of the Spatialparameter of PDSCH1 and PDSCH2 needs to be determined. Since PDSCH1 is determined to be called, PDSCH2 may not exist, and the beam of PDSCH1 is preferentially used to receive potential PDSCH1 and PDSCH2.

[0235] like Figure 1b In slotn, the base station schedules an aperiodic CSI-RS (Channel-state information reference signal measurement reference signal) for the terminal, wherein the spacing between the DCI for scheduling the aperiodic CSI-RS and the aperiodic measurement reference signal is greater than a predetermined threshold value K. The terminal in slotn also needs to detect CORESET0, which may schedule PDSCH for the terminal in slotn. Therefore, when the PDSCH and CSI-RS in slotn are in the same time domain symbol, the priority of the QCL parameters of PDSCH and CSI-RS needs to be determined. Similarly, since the aperiodic measurement reference signal is determined to have been scheduled, the terminal uses the aperiodic measurement reference signal to receive CSI-RS and potential PDSCH at least in the time domain symbol where the CSI-RS is located. In the time domain symbol where there is no aperiodic measurement reference signal in slotn, the QCL parameters of the CORESET with the lowest CORESETID in slotn can be used to obtain the QCL parameters of the potential PDSCH, or it is specified that the receiving beam of the aperiodic CSI-RS is used to receive PDSCH in the time domain symbol where the potential PDSCH is located in slotn.

[0236] from Figure 1a, 1b shows that even if the distance between PDSCH and the DCI that schedules PDSCH is less than the predetermined threshold K, the QCL parameters of PDSCH are not necessarily obtained by using the QCL parameters of the CORESET with the lowest CORESETID closest to PDSCH. It also depends on whether there is a second signal on the time domain symbol where PDSCH is located. When the second signal exists, at least the Spatial Rx parameter of the first signal is determined according to the Spatial Rx parameter of the second signal. When the second signal does not exist, the QCL parameters of PDSCH are obtained according to the QCL parameters of the CORESET with the lowest CORESETID closest to PDSCH, where the QCL parameters at least include the Spatial Rx parameter.

[0237] Figure 1c As shown, when the spacing between the PDSCH and the DCI scheduling the PDSCH is less than a predetermined threshold K, at least the Spatial Rx parameter of the PDSCH is obtained according to the Spatial Rx parameter of the lowest CORESETID in the time domain symbol closest to the PDSCH (that is, the SpatialRx parameter of the PDSCH is obtained according to the Spatial Rx parameter of CORESET1), rather than the Spatial Rx parameter of the CORESET with the lowest CORESETID in the slot closest to the PDSCH, that is, the Spatial Rx parameter of the PDSCH is not obtained according to the Spatial Rx parameter of CORESET0.

[0238] like Figure 1dAs shown, when the spacing between PDSCH and the DCI for scheduling PDSCH is less than a predetermined threshold value K, PDSCH needs to use the receiving beam of the CORESET in the slot closest to PDSCH to receive PDSCH, and the potential PDSCH can exist on any time domain symbol in the slot, so that on the time domain symbol where CORESET1 is located, it is necessary to receive the potential PDSCH and CORESET1 at the same time. When the receiving beam of CORESET1 is different from the receiving beam of CORESET0, or the two receiving beams cannot be simultaneously played by the terminal, it is necessary to specify the priority between the two. One way is to specify that the potential PDSCH on CORESET1 and CORESET1 are at least QCL with respect to the Spatial Rx parameter. Another way is to specify that PDSCH does not exist on CORESET1, where the spacing between PDSCH and the DCI for scheduling PDSCH is less than the predetermined threshold value K.

[0239] like Figure 1e As shown, when a terminal detects CORESET on multiple time domain symbols in a slot and needs to cache potential PDSCH, where the potential PDSCH indicates that the interval between the PDSCH and the DCI scheduling the PDSCH is less than a predetermined threshold K, the QCL parameters of the PDSCH are not obtained according to the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to the PDSCH (such as Figure 1e The QCL parameters of the PDSCH in the slot are not obtained based on the QCL parameters of CORESET0, but are obtained based on the QCL parameters of the CORESET with the lowest CORESETID in the first three time domain symbols in the slot closest to the PDSCH. The QCL parameters of the CORESET with the lowest CORESETID are obtained (such as Figure 1e The QCL parameters of PDSCH in are obtained according to the QCL parameters of CORESET1).

[0240] like Figure 1fAs shown, when it is determined in slotn that the base station has scheduled PDSCH for the terminal, that is, the interval between the DCI and PDSCH that schedule PDSCH is greater than the predetermined threshold K, and the base station also semi-statically configures the terminal to detect CORESET in slotn. At this time, one way is to stipulate that when the Spatial Rx parameter between CORESET and PDSCH is different on the time domain symbol where PDSCH is located, the terminal does not need to receive and detect CORESET on this time domain symbol, or the terminal and the base station stipulate that the DMRS of PDSCH at this time is at least QCL with respect to the Spatial Rx parameter of CORESET on the same time domain symbol as PDSCH. Or the terminal and the base station agree that when the PDSCH and CORESET are on the same time domain symbol and the receiving beams corresponding to the Spatial Rx parameters of the two are different, the PDSCH and CORESET are received with the receiving beam corresponding to the Spatial Rx parameter of CORESET.

[0241] Alternative Embodiment 9

[0242] In this embodiment, it is described how to obtain the QCL parameters of the PDSCH when the PDSCH occupies multiple slots.

[0243] The first question is how to obtain the distance between PDSCH and the DCI that schedules PDSCH. There are two ways to obtain it:

[0244] Time interval acquisition method 1, according to a time interval between the start symbol position of PDSCH and DCI in the frontmost slot of A slots occupied by PDSCH and a predetermined threshold value X1 (for example, K value, of course, the present application does not exclude the situation where X1 and K are different), obtain the method for obtaining the QCL parameter of PDSCH, for example, if the time interval is less than the predetermined threshold value X1, then the QCL parameter of PDSCH is obtained according to the QCL parameter of a specific CORESET in the slot closest to PDSCH (for example, the CORESET with the lowest CORESETID in the slot), if the time interval is greater than or equal to the predetermined threshold value X1, then the information indicated in the QCL parameter DCI of PDSCH is obtained, such as Figure 4b As shown;

[0245] The second time interval acquisition method is to obtain the QCL parameters of the PDSCH in each slot according to the A time intervals between the starting symbol position of the PDSCH and the DCI in each of the A slots occupied by the PDSCH and the predetermined threshold value X1 (for example, the K value, of course, the present application does not exclude the situation where X1 and K are different). For example, if the interval between the PDSCH and the DCI in the first A1 slots is less than the predetermined threshold value X1, then the QCL parameters of the PDSCH in the A1 slots are obtained according to the QCL parameters of the specific CORESET in the slot closest to the PDSCH (for example, the CORESET with the lowest CORESETID in the slot). The interval between the PDSCH and the DCI in the next A2 slots is greater than or equal to the predetermined threshold value X1, then the information indicated in the QCL parameter DCI of the PDSCH is obtained, such as Figure 4a as shown.

[0246] Another problem is that there are two ways to understand the acquisition of QCL parameters of the CORESET with predetermined characteristics in the slot closest to the PDSCH:

[0247] QCL acquisition method 1: The QCL parameters of PDSCH in A slots are obtained according to the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to the front slot in the A slots occupied by PDSCH. The QCL parameter acquisition method of PDSCH in A slots remains unchanged, or the QCL parameters of PDSCH in A slots remain unchanged;

[0248] QCL acquisition method 2: The QCL parameter of the PDSCH in the slot is obtained according to the QCL parameter of the CORESET with the lowest CORESETID in the slot closest to the A slots occupied by the PDSCH. The QCL parameter acquisition method of the PDSCH in the A slots can be different, or the QCL parameter of the PDSCH in the A slots can be changed;

[0249] The time interval acquisition methods 1 and 2 can be arbitrarily combined with the QCL parameter acquisition methods 1 and 2.

[0250] Specifically, when the time interval acquisition method 1 and the QCL acquisition method 1 are adopted, as Figure 4cAs shown, according to the time interval between the frontmost slot and DCI in the three slots occupied by PDSCH being less than the predetermined threshold K, the QCL parameters of PDSCH in the three slots are obtained according to the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to the frontmost slot (i.e., the QCL parameters of CORESET0 in slotn), and the QCL parameters of PDSCH in the three slots remain unchanged.

[0251] When using time interval acquisition method 1 and QCL acquisition method 2, such as Figure 4b As shown, according to the time interval between the frontmost slot of the three slots occupied by PDSCH and DCI being less than the predetermined threshold K, the QCL parameters of PDSCH in the three slots are obtained according to the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to each slot. The QCL parameters of PDSCH in the three slots can be different or the same.

[0252] When using the time interval acquisition method 2 and the QCL acquisition method 1, such as Figure 4d As shown, according to the relationship between the time interval between each of the three slots occupied by PDSCH and DCI and the predetermined threshold K, it is obtained whether the QCL parameter of each of the three slots is obtained according to CORESET or according to the information indicated by DCI. When the intervals between multiple slots of PDSCH and DCI are less than the threshold K, PDSCH is in these multiple slots (i.e. Figure 4d The QCL parameters in slotn, slotn+1) remain unchanged, and the QCL parameters of PDSCH are obtained according to the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to the front slot (i.e., slotn) among the multiple slots. If the interval between PDSCH and DCI in slotn+2 is greater than K, the QCL parameters of PDSCH in slotn+2 are obtained according to the information indicated by DCI.

[0253] When using the time interval acquisition method 2 and QCL acquisition method 2, such as Figure 4a As shown, according to the relationship between the time interval between each of the three slots occupied by PDSCH and DCI and the predetermined threshold K, it is obtained whether the QCL parameter of each of the three slots is obtained according to CORESET or according to the information indicated by DCI. When the intervals between multiple slots of PDSCH and DCI are less than the threshold K, PDSCH is in these multiple slots (i.e. Figure 4dThe QCL parameters of the PDSCH in each slot (slotn, slotn+1) are obtained according to the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to this slot. If the interval between the PDSCH in slotn+2 and DCI is greater than K, the QCL parameters of the PDSCH in slotn+2 are obtained according to the information indicated by the DCI. This PDSCH determines the interval between itself and the scheduled CORESET0 in each of the three slots. When the interval is less than K, the QCL parameters of the PDSCH are obtained using the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to this slot. When the interval is greater than K, the QCL parameters of the PDSCH are obtained using the QCL parameters indicated in the DCI. Figure 4a As shown, slotn uses the beam of CORESET0 in slotn to receive PDSCH, slotn+1 uses the beam of CORESET1 in slotn+1 to receive PDSCH, and slotn+2 uses the QCL parameter indicated by the DCI sent in CORESET0 in slotn to determine the receiving beam in slotn+2. This is because the terminal has not demodulated DCI in K time domain symbols, and needs to cache PDSCH, and both CORESET0 in slotn and CORESET1 in slotn+1 may schedule data for the terminal. Before the terminal detects DCI, it needs to cache the PDSCH scheduled by CORESET0 and / or CORESET1 in slotn+1. When the terminal's receiving capability is limited, for example, only one receiving beam can be sent, the PDSCH in each slot within the K range where DCI and PDSCH are less than a predetermined threshold uses the CORESET with the lowest CORESETID in the slot closest to the PDSCH in this slot to obtain the QCL parameter.

[0254] In particular, when the interval between PDSCH and DCI is greater than 1, there are A2 slots corresponding to a set of QCL parameters (such as Figure 4e ), or each of the A2 slots corresponds to a different set of QCL parameters (such as Figure 4f The specific method is further agreed upon by the base station and the terminal, or the base station notifies through signaling information.

[0255] The combination of the method for obtaining the specific time interval and the method for obtaining the QCL parameter can be agreed upon by the terminal and the base station, or the base station can notify the terminal of the combination through signaling information.

[0256] like Figures 4a to 4dIn , K is 26 time domain symbols, and the PDSCH scheduled by CORESET0 on slotn spans 3 slots, namely {slotn, slotn+1, slotn+2}.

[0257] exist Figure 4f In two slots where the interval between PDSCH and DCI is greater than a predetermined threshold value K, DCI will notify different QCL parameters for different slots, so that corresponding QCL parameters need to be configured for each slot in DCI. Of course, this embodiment does not exclude that the base station configures the QCL parameters of one of the multiple slots in DCI (for example, configures the QCL parameters in slotn+2, that is, configures the QCL parameters in the front slot), and the QCL parameters in other slots are configured through high-level signaling, or the QCL parameters in other slots are obtained according to the QCL parameters configured by DCI, such as using a polling method in multiple slots, for example, there are only two sets of QCL parameters notified by DCI and / or high-level signaling, and PDSCH occupies 4 slots, then these two sets are polled in these 4 slots. Figures 4a to 4f In the example, different QCL parameters correspond to different beams. The high-level signaling may be RRC signaling or MAC-CE command. The high-level signaling may be high-level signaling for notifying the candidate TCI state in the DCI. For example, when the DCI notifies that the TCI in slotn+2 is TCI state2 (the TCI field in the DCI includes 3 bits, corresponding to the 8 activated TCIstates), the TCI state of the PDSCH in slotn+3 corresponds to TCI state3.

[0258] In this optional embodiment, a PDSCH may repeatedly transmit data in multiple slots, or may transmit different data in multiple slots.

[0259] Alternative Embodiment 10

[0260] In this implementation, a state in the TCI domain notified in the DCI corresponds to multiple relationships, different relationships correspond to different time units or different time unit sets occupied by PDSCH, each relationship corresponds to a time unit occupied by PDSCH, or a time unit set, one relationship includes the relationship between Z DMRS groups and Z RS Sets, there is a one-to-one correspondence between the Z DMRS groups and the Z RS Sets, and the DMRS group and the corresponding RS Set satisfy the QCL relationship with respect to a QCL parameter set in the corresponding time unit or time unit set.

[0261] Optional Embodiment 11

[0262] In this embodiment, when the QCL parameters of the PDSCH / AP-CSI-RS are obtained according to the QCL parameters of the CORESET with the lowest CORESETID in the slot closest to the PDSCH / AP-CSI-RS, it is further clarified that the CORESET satisfies one of the following characteristics:

[0263] The CORESET with the lowest CORESETID is the CORESET with the lowest CORESETID among all CORESETs that the terminal needs to detect in all CCs in the time unit;

[0264] The CORESET with the lowest CORESETID is the CORESET with the lowest CORESETID among all CORESETs that the terminal needs to detect in the corresponding PCell in the time unit;

[0265] The CORESET with the lowest CORESETID is the CORESET with the lowest CORESETID among all CORESETs that the terminal needs to detect in the serving cell where the corresponding PDSCH is located in the time unit;

[0266] The CORESET with the lowest CORESETID is the CORESET with the lowest CORESETID among all CORESETs that the terminal needs to detect in the serving cell where the DCI corresponding to the scheduling PDSCH is located in the time unit;

[0267] The CORESET with the lowest CORESETID is the CORESET with the lowest CORESETID among all CORESETs that the terminal needs to detect and included in the serving cell where the predetermined CC (such as the CC with the lowest CCID) in the time unit is located;

[0268] The CORESET with the lowest CORESETID is the CORESET with the lowest CORESETID among all CORESETs that the terminal included in the predetermined CC group needs to detect in the time unit.

[0269] Optional Embodiment 12

[0270] In this embodiment, there is a correlation between the QCL parameter of a CORESET and whether the first communication node detects the beam recovery response signal.

[0271] Specifically, the base station configures an OCRESET for the terminal. When the terminal does not detect the beam recovery response signal, the base station informs the terminal of the QCL parameters of this CORESET through signaling. When the terminal needs to detect the beam recovery response signal (for example, 4 slots after the terminal sends the beam recovery request signal to the base station, the terminal detects the beam recovery response signal of the base station on this CORESET. When the predetermined time window is exceeded and the beam recovery response signal sent by the base station is not successfully detected, the terminal stops detecting the beam recovery request signal on this CORESET), the QCL parameters of this CORESET are obtained according to the beam found by the terminal in the beam recovery request signal sent by the terminal. Figure 8a As shown, in the T1 time period, the QCL parameter of CORESET1 is obtained through the signaling information notified by the base station. In the T2 time period, the terminal starts to detect the beam recovery request response signal sent by the base station on CORESET1. The QCL parameter of CORESET1 is obtained according to the reference signal indication information q included in the beam recovery request signal sent by the terminal. new Get, where q new Indicates the reference signal indication information selected by the terminal in a reference signal set (that is, indicates the newly selected beam of the terminal). In the T3 time period, the QCL parameter of CORESET1 is obtained through the signaling information sent by the base station, wherein the signaling information about the QCL parameter of CORESET1 sent by the base station to the terminal in the T1 time period and the T3 time period may be different signaling information, that is, the base station may update the QCL parameter of CORESET1 through the signaling information in the T2 time period. The new beam discovered by the terminal in the beam recovery request signal sent by the terminal is obtained through the reference signal indication information sent by the terminal, wherein the reference signal indication information indicates the reference signal selected by the terminal in a reference signal set. The reference signal includes a measurement reference signal and / or a synchronization reference signal.

[0272] Optional Embodiment 13

[0273] In this embodiment, the physical layer dynamic control signaling for scheduling the aperiodic measurement reference signal may be after the aperiodic measurement reference signal.

[0274] Optionally, the non-periodic measurement reference signal and the physical dynamic control signaling are in the same time unit.

[0275] like Figure 8b The starting time domain symbol of the DCI for scheduling the aperiodic measurement reference signal is after the aperiodic measurement reference signal. Figure 8c As shown, the part of time domain symbols where the DCI for scheduling the aperiodic measurement reference signal is located is after the aperiodic measurement reference signal, that is, for example, the DCI is on 3 time domain symbols, and the CSI-RS is on the first time domain symbol where the DCI is located.

[0276] In an optional embodiment, the TCI indication information is used to indicate the QCL relationship between the DMRS group / CSI-RS port group and the DL-RS set, that is, one TCI index information corresponds to one state, one state includes the corresponding relationship between Q DMRS groups and Q DL-RS sets, one DL-RS set includes one or more DL-RSs, and each DL-RS is associated with a QCL parameter set, indicating that the reference signal in the DMRS group / CSI-RS port group and a DL-RS in the DL-RS set associated therewith satisfy a QCL (quasi-co-location) relationship with respect to the QCL parameter set. Two reference signals satisfy a quasi-co-location relationship with respect to one QCL parameter, indicating that the QCL parameter of one reference signal can be obtained by the QCL parameters of two reference signals, wherein the QCL parameter includes at least one of the following parameters:

[0277] Doppler shift, Doppler spread, average delay, delay spread, average gain, Spatial Rx parameter.

[0278] In this optional embodiment, the two reference signals are QCL, which means that the two reference signals are QCL at least with respect to the SpatialRx parameter, and there is no restriction on whether the two reference signals are QCL with respect to other QCL parameters.

[0279] In an optional embodiment, the channel may also be a signal, that is, a signal is transmitted on the channel, such as a data signal is transmitted on a data channel.

[0280] In an optional embodiment, different CCs (component carriers) may be associated via different ServingcellIDs.

[0281] Optional Embodiment 14

[0282] In this optional embodiment, the terminal does not want to receive a configuration that satisfies the following characteristics: the PDSCH and CSI-RS on the same time symbol do not satisfy the QCL relationship with respect to the reception space parameters.

[0283] Optionally, the interval between the above-mentioned PDSCH and the control signaling for scheduling the PDSCH is less than a predetermined threshold K.

[0284] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.
