Description

[Technical field]

[0001] This application claims priority from Chinese Patent Application No. 201810160248.2, filed with the China Intellectual Property Office (CNIPA) on February 26, 2018, the entire contents of which are incorporated herein by reference.

[0002] Technical Field The present application relates to the field of communications, for example to methods and apparatus for transmitting and receiving control signaling, and methods for determining information. [Background technology]

[0003] background As one of the basic technologies of the fifth generation wireless system (5G), high frequency communication strongly supports the high speed and wide bandwidth of future communication. However, a key problem of high frequency communication is that the path loss is relatively large, while the size of the antenna is relatively small. In view of this, the path loss may be reduced by forming a beam using multiple antennas.

[0004] In order to improve system efficiency, resist beam jamming scenarios, and recover high-speed links, the beam of the downlink signal can be notified by physical layer dynamic control signaling. If 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 through the information notified by the physical layer dynamic control signaling.

[0005] In the related New Radio (NR) protocol, when the interval between the physical layer dynamic control signaling and the downlink signal is less than a predefined threshold, the minimum control resource set identification (CORE) in the nearest slot is used. A beam of a control resource set (CORESET) having a CORESET ID is used to cache data.

[0006] There are two situations in the previous solution. The first situation is that when the interval between the physical layer dynamic control signaling and the downlink signal is less than a predetermined threshold, the bit field for reporting the beam in the physical layer dynamic control signaling is not fully utilized. The second situation is that the downlink signal needs to be cached before decoding the physical layer dynamic control signaling, but in fact the downlink signal may not be scheduled by the base station. The terminal may not be able to detect the closest CORESET If a dynamically scheduled potential downlink signal needs to be cached according to a CORESET having an ID and according to a rule, and if a previously scheduled signal may be present at the location where the potential downlink signal is located, and if the terminal cannot simultaneously generate a beam for the previously scheduled downlink signal and a beam for the potential downlink signal, then the base station and the terminal need to agree on a behavior to ensure the validity of communication.

[0007] No effective solutions to the previous technical problems in the related art have yet been proposed. Summary of the Invention [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Detailed Description Hereinafter, the present application will be described together with embodiments with reference to the drawings.

[0021] It should be noted that terms such as "first" and "second" in the specification, claims, and drawings of this application are used to distinguish between similar items and are not necessarily used to describe a particular order or sequence.

[0022] EMBODIMENT 1 This embodiment provides a method for transmitting control signaling. Figure 1 is a flowchart of a method for transmitting control signaling according to an embodiment of the present application. As shown in Figure 1, the process includes the following steps S102 and S104.

[0023] In step S102, the second information is determined according to the first information. The second information includes at least one of: a number N of bits used in the first control signaling to notify the first transmission parameter; a correspondence mapping table between an index value referenced by the first transmission parameter in the first control signaling and the value of the first transmission parameter; a type of the first transmission parameter notified by a predetermined indication field in the first control signaling; or position information of the bits used in the first control signaling to notify the first transmission parameter; and the first information includes a relationship between a transmission time interval between the first control signaling and the first signal and a predetermined threshold value K, where N and K are non-negative integers.

[0024] In step S104, a first control signaling is transmitted. In an embodiment, the first control signaling is transmitted according to the determined second information.

[0025] In the above step, the second information is determined according to the first information, and the second information includes at least one of the number N of bits used in the first control signaling to notify the first transmission parameter, the correspondence mapping table between the index value referenced by the first transmission parameter in the first control signaling and the value of the first transmission parameter, the type of the first transmission parameter notified by the predetermined indication field in the first control signaling, or the position information of the bit used in the first control signaling to notify the first transmission parameter, and the first information includes a relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold value K, where N and K are non-negative integers, and the first control signaling is transmitted. That is, the format of the control signaling is determined according to the second information, and then the new control signaling is transmitted. In this way, the following defects in the related art are overcome. The defect is that when the interval between the physical layer dynamic control signaling and the downlink signal is less than a predetermined threshold, the bit field for notifying the beam in the physical layer dynamic control signaling is not fully utilized, resulting in relatively low resource utilization, but the resource utilization of the control signaling is improved.

[0026] In some embodiments, the above steps may be performed by, but are not limited to, a base station.

[0027] In one embodiment, steps S102 and S104 may be performed in the reverse order, i.e., step S104 may be performed before step S102.

[0028] In one embodiment, when the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a first relationship, the value of N includes N1, and when the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship, the value of N includes N2, where N1 and N2 are integers.

[0029] The relationship between N1 and N2 is that N1 is greater than N2, and the difference between N1 and N2 is the number of bits occupied by the transmission configuration indication (TCI) field. or the difference between N1 and N2 is equal to or less than the number of bits required to inform information about the second transmission parameter.

[0030] In one embodiment, when a relationship between a transmission time interval between the first control signaling and the first signal and a predetermined threshold K is a first relationship, the corresponding mapping table is a first corresponding mapping table, and when a relationship between a transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship, the corresponding mapping table is a second mapping table.

[0031] In an embodiment, any one of the first corresponding mapping table, the second corresponding mapping table, the transmission parameter value set 1 and the transmission parameter value set 2 is determined in at least one of the following manners, in which in manner 1, the content is included in the signaling information to be transmitted, and in manner 2, the rule is pre-agreed upon by the transmitting end and the receiving end. The transmission parameter value set 1 corresponds to the value set of the first transmission parameter included in the first corresponding mapping table, and the transmission parameter value set 2 corresponds to the value set of the first transmission parameter included in the second corresponding mapping table.

[0032] In an embodiment, when the type of the first transmission parameter is TCI, the downlink reference signal (DL-RS) set formed by the downlink reference signals (DL-RS) corresponding to the spatial Rx parameters of each state in the first correspondence mapping table includes one DL-RS When the first transmission parameter includes only the DL-RS set and the type of the first transmission parameter is TCI, each two DL-RSs in the DL-RS set formed by the DL-RSs associated with the spatial Rx parameters of each state in the first correspondence mapping table satisfy the QCL relationship for the spatial Rx parameters.

[0033] When the type of the first transmission parameter is TCI, the DL-RSs of the DL-RS set formed by the DL-RSs associated with the spatial Rx parameters of each state in the first corresponding mapping table can be simultaneously received by the first communication node, and when the type of the first transmission parameter is TCI, the DL-RS set formed by the DL-RSs associated with the spatial Rx parameters of each state in the first corresponding mapping table is an empty set. The first communication node is a communication node for receiving at least one of a first signal or a first control signaling.

[0034] In an embodiment, the first transmission parameter type includes one or more transmission parameter types included in the first control signaling, excluding a transmission parameter type of a TCI, or the first transmission parameter type is a transmission parameter of a TCI.

[0035] In one embodiment, the first transmission parameter is a first signal or the first transmission parameter is a transmission parameter of the second signal.

[0036] In an embodiment, the first signal or the second signal includes at least one of a demodulation reference signal, a measurement reference signal, a control channel signal, or a data channel signal, and the first control signaling is a physical layer control signaling.

[0037] In one implementation, the first information comprises information contained in the second control signaling, the information relating to whether a transmission configuration indication present in downlink control information (TCI-PresentInDCI) present in the downlink control information corresponding to the CORESET in which the first control signaling is located is enabled or not. information on a relationship between a carrier frequency at which the first signal or the second signal is located and a predetermined threshold G; information on a supported frequency range capability fed back by the first communication node; information on whether the predetermined threshold K is 0; information on whether at least one CORESET configured with spatial Rx parameters is present in a CORESET that needs to be detected by the first communication node; information on whether at least one CORESET configured with spatial Rx parameters is present in a CORESET associated with a dedicated search space that needs to be detected by the first communication node; information on whether a CORESET with a minimum control resource set ID (CORESET ID) in a time unit closest to the first signal or the second signal is configured with spatial Rx parameters; information on a minimum CORESET in a time domain symbol closest to the first signal or the second signal. and / or information on whether a CORESET having an ID is configured with spatial Rx parameters, information on whether at least one TCI state exists in a TCI state pool associated with the first signal or the second signal, where QCL parameters corresponding to a reference signal (RS) set in the TCI state include spatial Rx parameters, or information on whether at least one TCI state exists in an activation TCI state pool associated with the first signal or the second signal, where QCL parameters corresponding to a RS set in the TCI state include spatial Rx parameters. The first communication node is a communication node for receiving at least one of the first signal or the second signal.

[0038] In one embodiment, the first control signaling is a physical layer control signaling, a media access control (MAC) control element (CE) The first control signaling includes at least one of physical layer control signaling, MAC-CE control signaling, or radio resource control (RRC) signaling, and the second control signaling includes at least one of physical layer control signaling, MAC-CE control signaling, or RRC signaling.

[0039] In one embodiment, if the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a first relationship, the type of the first transmission parameter notified by the predetermined indication field in the first control signaling is a first type of transmission parameter, and if the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship, the type of the first transmission parameter notified by the predetermined indication field in the second control signaling is a second type of transmission parameter.

[0040] In an embodiment, when the transmission time interval between the first control signaling and the first signal is less than a predetermined threshold K, the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a first relationship, and when the transmission time interval between the control signaling and the first signal is equal to or greater than the predetermined threshold K, In the case where the transmission time interval between the first control signaling and the first signal is equal to or less than the predetermined threshold K, the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship. Alternatively, if the transmission time interval between the control signaling and the first signal is equal to or less than the predetermined threshold K, the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a first relationship, and if the transmission time interval between the control signaling and the first signal is greater than the predetermined threshold K, the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship. Alternatively, if the transmission time interval between the control signaling and the first signal is equal to or greater than the predetermined threshold K, the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a first relationship, and if the transmission time interval between the control signaling and the first signal is less than the predetermined threshold K, the relationship is a second relationship.

[0041] The present embodiment will now be described, by way of example, together with specific examples. Illustrative embodiment 1 In beam-based communication, the beam of the PDSCH can be notified by downlink control information (DCI). If the interval between the DCI and the PDSCH is less than K, the terminal needs a radio frequency to receive and cache the PDSCH before decoding the DCI, so in the relevant NR, if the interval between the DCI and the PDSCH is less than a predetermined threshold K, the terminal obtains a demodulation reference signal (DMRS) of the PDSCH according to a QCL parameter corresponding to the smallest CORESET ID in the nearest slot, and if the interval between the DCI and the PDSCH is less than the .... It is specified that if the value is equal to or greater than K, the QCL parameter of the DMRS of the PDSCH is obtained by using the QCL information indicated in the DCI. However, in order to reduce the complexity of the terminal blindly detecting the physical downlink control channel (PDCCH), the load of the PDCCH when the interval between the DCI and the PDSCH is less than K is the same as the load of the PDCCH when the interval between the DCI and the PDSCH is equal to or greater than K. Thus, when the interval between the DCI and the PDSCH is less than K, a 3-bit TCI indication field (the TCI indication field is used to indicate the QCL parameter of the DMRS of the PDSCH) is present in the DCI but is not used. In the related NR version, the TCI indication field occupies 3 bits. For this reason, the following improved solution is proposed.

[0042] If the interval between the DCI and the PDSCH is less than K, the 3-bit TCI indication field in the DCI may indicate one or more transmission parameters (i.e., first transmission parameters) in the DCI, excluding the transmission parameters of the TCI, and the associated transmission parameters of the NR DCI format_1 are shown in order in Table 1. As shown in Table 1, the interval between the DCI and the PDSCH may be determined according to the information indicated in the transmission parameter indicator 5.

[0043] [Table 1]

[0044] 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 PUCCH resource indicator can indicate one PUCCH resource selected from a maximum of 32 PUCCH resources by using a total of 5 bits including the bit field numbered 14 and the bit field numbered 17 in Table 1. In an embodiment, when it is determined that the PUCCH set is set 0 according to the uplink control information (UCI) load, the index of the PUCCH resource of set 0 can be indicated together using two bit fields, and when it is determined that the PUCCH set is not set 0 according to the UCI load, although the interval is less than K, the PUCCH resource can be notified only using the bit field numbered 14 in Table 1, instead of indicating it together using the bit field numbered 14 and the bit field numbered 17 in Table 1. This is because the maximum number of PUCCH resources included in these sets is 8. If the interval between DCI and PDSCH is equal to or greater than K, the PUCCH resource can be indicated by only using indicator number 14 in Table 1, selecting one PUCCH resource from a maximum of four PUCCH resources. If the interval between DCI and PDSCH is less than K, the sequence of indicators in DCI may follow the sequence in Table 1, and only indicator 14 and indicator 17 together form the PUCCH resource indicator. Alternatively, the sequence of transmission parameter indicators may be used as shown in Table 2. Compared to Table 1, the changes in Table 2 are that transmission parameter indicator 17 is deleted and the number of bits of transmission parameter indicator 14 is 5 bits.

[0045] [Table 2]

[0046] In this way, when the interval between the DCI and the PDSCH is less than the predetermined threshold K, dynamic selection can be performed for 32 PUCCH resources of the DCI, as shown in Table 3, and when the transmission interval between the DCI and the PDSCH is equal to or greater than the predetermined threshold K, dynamic selection can be performed for only 4 PUCCH resources of the DCI, as shown in Table 4.

[0047] [Table 3]

[0048] [Table 4]

[0049] In Table 3 and Table 4, the four PUCCH resources in Table 4 are the same as the four PUCCH resources in Table 3. In this way, when the base station performs notification, only 32 PUCCH resources need to be notified. Of course, this embodiment does not exclude the case where the PUCCH resources in Table 3 are different from the PUCCH resources in Table 4. In this way, when the base station performs notification using higher layer signaling, the PUCCH resources in Table 3 and Table 4 are notified separately.

[0050] In this embodiment, the interval between the DCI and the PDSCH may be at least one of the interval between the end time domain symbol of the DCI and the start time domain symbol of the PDSCH, the interval between the start time domain symbol of the DCI and the start time domain symbol of the PDSCH, the interval between the latest time domain symbol of the end symbol of the CORESET in the slot in which the DCI is located and the start time domain symbol of the PDSCH, the interval between the earliest time domain symbol of the CORESET in the slot in which the DCI is located and the start time domain symbol of the PDSCH, the interval between the end time domain symbol of the DCI and the start time domain symbol in each of the multiple slots occupied by the PDSCH, or the interval between the start time domain symbol of the DCI and the start time domain symbol in each of the multiple slots occupied by the PDSCH.

[0051] In the above description, the TCI field is used to indicate the PUCCH resource when the interval between DCI and PDSCH is less than a predetermined threshold K. Similarly, it is also possible to use the TCI field for the rate matching indicator when the interval between DCI and PDSCH is less than a predetermined threshold. Similarly, when the rate matching information is configured through higher layer signaling, two sets of rate matching parameters need to be configured, for example, one set of parameters used to build a table similar to Table 3 and another set of parameters used to build a table similar to Table 4. As an alternative, one set of parameters is used, all entries of this set of parameters are used to build a table similar to Table 3, and an agreed part of the entries (for example, the first M entries or the last M entries) are used to build a table similar to Table 4. In this case, Table 3 and Table 4 show the correspondence between index values ​​and rate matching information, and the number of states in Table 3 and the number of states in Table 4 change. For example, if the higher layer configured rate matching PDSCH resource set includes two resources, and the interval between the DCI and the PDSCH is less than a predetermined threshold, refer to Table 5 to obtain the rate matching information, and Table 5 includes a total of 2 (1+3) There are index values ​​of =16, and the index values ​​are jointly indicated by transmission parameter indicator 8 and transmission parameter indicator 17 in Table 1. If the transmission interval between DCI and PDSCH is equal to or greater than a predetermined threshold, the rate matching information is obtained by referring to Table 6, and Table 6 includes (1) There are two possible states: 0x0, 0x1, and 0x2, which are indicated by transmit parameter indicator 8 in Table 1.

[0052] [Table 5]

[0053] [Table 6]

[0054] Similarly, if the interval between the DCI and the PDSCH is less than a predetermined threshold K, the TCI field may be used for one or more transmission parameters of the 20 parameters other than the TCI transmission parameter in Table 1. For example, if the interval between the DCI and the PDSCH is less than a predetermined threshold K, the first bit of the three bits of the TCI field may be used to report rate mating information, and the last bit of the three bits of the TCI field may be used to report rate mating information. The last two bits are used for zero power channel state information reference signal (ZP-CSI-RS) information. Then, when the interval between the DCI and the PDSCH is less than a 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 according to an agreed rule or signaling information. For example, the base station indicates through signaling that when the interval between the DCI and the PDSCH is less than a predetermined threshold K, the first bit of the TCI field is used to report rate mating information and the last two bits of the TCI field are used to report ZP-CSI-RS information. As an alternative, the base station indicates through signaling that when the interval between the DCI and the PDSCH is less than a predetermined threshold K, all three bits of the TCI field are used to report rate mating information. As an alternative, the base station indicates through signaling that when the interval between the DCI and the PDSCH is less than a predetermined threshold K, the first two bits of the TCI field are used to report PDSCH frequency domain resources and the last bit of the TCI field is used to report ZP-CSI-RS information.

[0055] In the above embodiment, when the interval between the DCI and the PDSCH is less than K, the TCI field is used to indicate other types of transmission parameters other than the transmission parameters of the TCI in Table 1, and may be used to indicate a transmission parameter type not present in Table 1. For example, the TCI field is used to indicate CSI information (the CSI information is used to trigger the reporting of at least one of aperiodic CSI-RS or aperiodic CSI). Thus, when the interval between the DCI and the PDSCH is less than K, the TCI field in the DCI is used to indicate CSI trigger information, and when the interval between the DCI and the PDSCH is greater than K, the TCI field is used to indicate TCI information, in which case the CSI information cannot be indicated in the DCI.

[0056] Illustrative embodiment 2 In this embodiment, at least one of information on a transmission parameter type indicated by a specified indicator of the physical layer dynamic control signaling, or information on whether the physical layer dynamic control signaling includes indication information indicating a specified transmission parameter type, is determined according to a relationship between a transmission interval between the physical layer dynamic control signaling and the first signal and a predetermined threshold value.

[0057] In one embodiment, if the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is relationship 1, the designated indicator of the physical layer dynamic control signaling is used to indicate a first type of transmission parameter, and if the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is relationship 2, the designated indicator of the physical layer dynamic control signaling is used to indicate a second type of transmission parameter.

[0058] In an embodiment, when a relationship between a transmission time interval between the first control signaling and the first signal and a predetermined threshold value K is a relationship 1, the physical layer dynamic control signaling includes indication information indicating a specified transmission parameter type, and the first control signaling When the relationship between the transmission time interval between the first signal and the second signal and the predetermined threshold K is Relationship 2, the physical layer dynamic control signaling does not include indication information indicating a specified transmission parameter type.

[0059] In one embodiment, relationship 1 is that the transmission interval between the physical layer dynamic control signaling and the first signal is less than a predetermined threshold, and relationship 2 is that the transmission interval between the physical layer dynamic control signaling and the first signal is greater than or equal to a predetermined threshold. Alternatively, relationship 1 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 relationship 2 is that the transmission interval between the physical layer dynamic control signaling and the first signal is greater than a predetermined threshold.

[0060] In an embodiment, the transmission parameters may be transmission parameters of the first signal or may be transmission parameters of the second signal.

[0061] In one embodiment, when the transmission time interval between the DCI and the PDSCH (first signal) is less than K, the indicator of DCI number 17 in Table 1 is used to indicate rate mating indication information, and when the transmission time interval between the DCI and the PDSCH is equal to or greater than K, the indicator of DCI number 17 in Table 1 is used to indicate TCI information.

[0062] Alternatively, when the transmission time interval between the DCI and the PDSCH (first signal) is less than K, the indicator of DCI number 17 in Table 1 is used to indicate CSI request information, and when the transmission time interval between the DCI and the PDSCH is equal to or greater than K, the indicator of DCI number 17 in Table 1 is used to indicate TCI information (i.e., information about the QCL parameter of the DMRS of the PDSCH). That is, when the interval between the DCI and the PDSCH is less than K, the DCI in the DL grant includes CSI request indication information, and when the interval between the DCI and the PDSCH is equal to or greater than K, the DCI in the DL grant does not include CSI request indication information.

[0063] Illustrative embodiment 3 In the above exemplary embodiment 1 and exemplary embodiment 2, the number of candidate parameter values ​​included in the first transmission parameter value set varies according to a first relationship. For example, when the interval between the DCI and the PDSCH is less than K, the first transmission parameter value set includes the X1 value, and when the interval between the DCI and the PDSCH is greater than K, the first transmission parameter value set includes the X2 value. Alternatively, when the interval between the DCI and the 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 (such as Table 3), and when the interval between the DCI and the 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 (such as Table 4).

[0064] In an embodiment, whether the TCI field is present in the DCI is also configured for each CORESET. The DCI in CORESET1 is configured to have no TCI field, i.e., the DCI in CORESET1 does not include the transmission parameter indicator number 17 in Table 1. The DCI in CORESET2 is configured to have the TCI field present, i.e., the DCI in CORESET2 includes the transmission parameter indicator number 17 in Table 1. In addition, the DCI and the PDSCH It is agreed that if it is agreed that the transmission interval between the DCI and the PDSCH is less than an agreed threshold (such as K), the TCI field in the DCI is used to indicate the rate mating information. Thus, the index values ​​and rate mating information referred to by the rate mating information indicated in the DCI transmitted in CORESET2 are shown in two tables, namely Table 5 and Table 6. If the interval between the DCI and the PDSCH is less than a predetermined threshold, Table 5 is referred to, and if the interval between the DCI and the PDSCH is equal to or greater than the predetermined threshold, Table 6 is referred to, and the index values ​​and rate mating information referred to by the rate mating information indicated in the DCI in CORESET1 also refer to Table 6. Alternatively, the index values ​​and rate mating information referred to by the rate mating information indicated in the DCI in CORESET1 refer to a different table than Table 6, such as Table 6-2, i.e., in this case, there are three tables referred to by the rate mating information. In this way, when the base station notifies the rate mating information through higher layer signaling, the base station needs to notify the rate mating information for each table, or the higher layer notifies the information of Table 6 and Table 5 through one signaling and notifies the information of Table 6-2 through another signaling.

[0065] That is, when the transmission interval between the DCI and the PDSCH is less than K, the table referenced by the index information of the rate mating information indicated in the DCI is Table 5. In other cases, the table referenced by the index information of the rate mating information indicated in the DCI is Table 6. When the TCI field is not present in the DCI, the table referenced by the index information of the rate mating information indicated in the DCI is Table 6, or the table referenced by the index information of the rate mating information indicated in the DCI is Table 6-2.

[0066] In the above implementation, there are Y tables referenced by the rate mating information indicated in the DCI. Similarly, there may be Y tables referenced by other transmission parameter types indicated in the DCI. In the above implementation, Y is a number greater than 1, such as Y=2 or Y=3.

[0067] Illustrative embodiment 4 In the above embodiment, the second information is determined according to the first information. The second information includes at least one of the following information: the number N of bits used in the control signaling to notify the first transmission parameter, a correspondence table between the value of the first transmission parameter and a reference index value for notifying information on the first transmission parameter in the control signaling, the type of the first transmission parameter notified by a predetermined indication field in the control signaling, or the position information of the bit used in the control signaling to notify the first transmission parameter. The first information includes a relationship between a predetermined threshold value and a transmission time interval between the control signaling and the first signal.

[0068] In this embodiment, the first information further includes at least one of the following information 1 to 10.

[0069] Information 1: Information included in the second control signaling. For example, the base station transmits signaling information to the terminal, and at least one of the following information is notified in the signaling information: whether the TCI field can be used for notification of another transmission parameter type, the transmission parameter type that can use the TCI field for notification, or the transmission parameter type that can use a bit of the TCI field for notification. The information notified in the second control signaling is used to determine the second information. It is used.

[0070] Information 2: TCI-PresentInDCI parameter associated with the CORESET in which the first control signaling is located. The TCI-PresentInDCI is used to set whether a TCI field is present in the DCI of the DL grant transmitted in the CORESET, i.e., whether the indicator number 17 in Table 1 is present. For example, if the TCI-PresentInDCI associated with the CORESET is not enabled, there is no TCI field in the DCI in the CORESET, and the number of bits used by the first transmission parameter remains unchanged regardless of whether the transmission time interval between the DCI and the PDSCH is less than the predetermined threshold K or not.

[0071] Information 3: Whether the carrier frequency where the signal is located is below a predetermined threshold K. For example, if the PDSCH is below 6 GHz, the mechanism for determining the second information according to the first information is not initiated. Alternatively, information 3 is information about the terminal transmitting a frequency domain range that it can process, and if the terminal's ability to process the frequency domain is FR1 (i.e., the frequency domain range that the terminal can process is below a predetermined threshold, e.g., below 6 GHz), the mechanism for determining the second information according to the first information is not initiated.

[0072] Information 4: Whether at least one CORESET configured in the spatial Rx parameters exists in the CORESET set that needs to be detected by the first communication node. For example, if the CORESET configured in the spatial Rx parameters does not exist in the CORESET set that needs to be detected by the terminal, the mechanism for determining the second information according to the first information is not initiated.

[0073] Information 5: Whether at least one CORESET configured with spatial Rx parameters exists in a CORESET corresponding to a dedicated search space that needs to be detected by the first communication node. For example, if a CORESET configured with spatial Rx parameters does not exist in a CORESET corresponding to a dedicated search space that needs to be detected by the terminal, the mechanism for determining the second information according to the first information is not initiated.

[0074] Information 6: Whether the CORESET with the smallest CORESET ID in the time unit closest to the signal is configured in the spatial Rx parameters. For example, if the CORESET with the smallest CORESET ID in the time unit closest to the PDSCH / Aperiodic CSI-RS (AP-CSI-RS) is not configured in the spatial Rx parameters, the mechanism for determining the second information according to the first information is not initiated.

[0075] Information 7: Whether the CORESET with the smallest CORESET ID in the time domain symbol closest to the signal is configured in the spatial Rx parameters. For example, the smallest CORESET in the time domain symbol closest to the PDSCH / AP-CSI-RS If the CORESET with the ID is not configured with spatial Rx parameters, the mechanism for determining the second information according to the first information is not initiated.

[0076] Information 8: Whether at least one TCI state exists in the TCI state pool associated with the signal. The QCL parameters corresponding to the RS set of the TCI state include spatial Rx parameters. For example, if there is no TCI state in the TCI state pool 1 configured by the RRC associated with the PDSCH, and the QCL parameters corresponding to one DL-RS of the TCI state include spatial Rx parameters, the mechanism for determining the second information according to the first information is not initiated.

[0077] Information 9: Whether at least one TCI state exists in the activation TCI state pool associated with the signal. The QCL parameters corresponding to the RS set of the TCI state include a spatial Rx parameter. For example, if the TCI state does not exist in the MAC-CE activation TCI state pool associated with the PDSCH or in the TCI state pool formed by the TCI state that the TCI field of the DCI can indicate, and the QCL parameters corresponding to one DL-RS of the TCI state include a spatial Rx parameter, the mechanism for determining the second information according to the first information is not initiated.

[0078] Information 10: Information about the ability to process a frequency domain range reported by the first communication node. For example, if the frequency domain range that the terminal can process reported by the terminal is FR1 (i.e., the frequency domain range that the terminal can process is less than 6 GHz), the mechanism for determining the second information according to the first information is not initiated. If the frequency domain range that the terminal can process reported by the terminal is FR2 (i.e., the frequency domain range that the terminal can process is 6 GHz or more), the mechanism for determining the second information according to the first information is not initiated.

[0079] Illustrative embodiment 5 In this embodiment, the table referenced by the TCI field signaled in the DCI is determined according to the relationship between the interval between the DCI and the PDSCH and a predetermined threshold K.

[0080] In one embodiment, when the interval between the DCI and the PDSCH is less than a predetermined threshold K, the table referred to by the TCI in the DCI is Table 7, and when the interval between the DCI and the PDSCH is equal to or greater than the predetermined threshold K, the table referred to by the TCI in the DCI is Table 8. TCI states 10 to 17 and TCI states 20 to 27 are configured by different higher layer control signaling. The higher layer control signaling includes at least one of RRC signaling or MAC-CE signaling.

[0081] In an embodiment, if the interval between the DCI and the PDSCH is less than K, the spatial Rx parameters of the DMRS of the PDSCH are obtained according to an agreed rule (e.g., the spatial Rx parameters of the DMRS of the PDSCH are obtained according to the configuration of the spatial Rx parameters of the CORESET with the smallest CORESET ID in the nearest slot), and other QCL parameter information of the DMRS of the PDSCH is obtained according to the TCI field in the DCI and with reference to Table 7. Alternatively, all QCL parameters of the DMRS of the PDSCH are obtained according to the information indicated by the TCI field in the DCI and with reference to Table 7, and the configuration of Table 7 is restricted. If the interval between the DCI and the PDSCH is equal to or greater than K, all QCL parameters of the DMRS of the PDSCH are obtained according to the information indicated by the TCI field in the DCI and with reference to Table 8.

[0082] [Table 7]

[0083] [Table 8]

[0084] One state is used to establish the correspondence between the Q DMRS groups of the PDSCH and the Q DL-RS sets, where Q is an integer equal to or greater than 1. As shown in Table 9, the correspondence (DMRS group 1, DL-RS set 1) and (DMRS group 2, DL-RS set 2) are established in TCI state n, where DL-RS set 1 includes {DL-RS1, DL-RS2} and DL-RS set 2 includes DL-RS3. In DMRS group 1, a QCL relationship exists for the QCL parameters of QCL type 1 and DL-RS1, where each QCL type includes at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, average gain, or spatial Rx parameter. The DL-RS includes the CSI-RS / synchronization signal and the physical broadcast channel (PBCH) block (SSB) / PBCH block (SSB). The DMRS group may be referred to as a QCL target reference signal, and the DL-RS may be referred to as a QCL reference signal.

[0085] [Table 9]

[0086] In an embodiment, the QCL type associated with each TCI state in Table 7 includes a spatial Rx parameter, and the DL-RS set formed by the QCL parameter has a predetermined restriction condition including at least one of the following: the DL-RS set includes only one DL-RS, each of two DL-RSs in the set is QCL with respect to the spatial Rx parameter, the DL-RSs in the set may be received simultaneously by the terminal, the DL-RS set is an empty set, or the DL-RSs in the set belong to one group, which may be assigned by the base station or reported by the terminal. In an embodiment, for example, the corresponding QCL-types of the eight states in Table 7 include DL-RSs of spatial Rx parameters, which include {DL-RS100, DL-RS101, DL-RS102, DL-RS103, DL-RS104, DL-RS105, DL-RS106, DL-RS107} (i.e., the DMRS group of state i and DL-RS10i satisfy the QCL relationship for at least the spatial Rx parameters, where i=0, 1, ..., 7). Each two DL-RSs in this set are QCLs for the spatial Rx parameters, or these DL-RSs may be received by the terminal simultaneously, or the DL-RSs of the spatial Rx parameters included in the corresponding QCL-types of the eight states in Table 7 are all DL-R100, or all QCL-types associated with the DL-RSs of the eight states in Table 7 do not include spatial Rx parameters. In this case, it is agreed that the spatial Rx parameters of the DMRS of the PDSCH are obtained according to an agreed rule, for example, in this case the DMRS of the PDSCH and the DMRS of the minimum CORESET ID are QCL for the spatial Rx parameters.

[0087] In one embodiment, when the interval between the DCI and the PDSCH is less than a predetermined threshold K, the table referred to by the TCI field included in the DCI is Table 7, and when the interval between the DCI and the PDSCH is equal to or greater than the predetermined threshold K, the table referred to by the TCI field in the DCI is Table 8. The configuration of the DL-RS associated with the spatial Rx parameters of the TCI states in Table 7 is limited, i.e., there is one or a finite number of beams associated with these TCI states, and thus, in this case, the terminal has not decoded the DCI and the terminal needs to know the spatial Rx parameters of the PDSCH before the DCI is decoded. However, in Table 8, there is no such limitation. For this reason, both Table 7 and Table 8 are necessary.

[0088] The configuration of Table 7 is configured through higher layer signaling. Multiple Tables 7 may be configured to allow different beams to be used at different times even if the transmission time interval between DCI and PDSCH is less than K. The effective time domain pattern for each Table 7 is configured. For example, the period and period offset of Table 7-1 are configured, and the period and period offset of Table 7-2 are configured. In the case of the DCI, the period and period offset are set. Alternatively, there are two Tables 7, namely Table 7-1 and Table 7-2. The period and period offset of Table 7-1 are set. For other slots, Table 7-2 is referred to. That is, if the DCI is included in a slot shown in Table 7-1, the TCI field reported in the DCI refers to Table 7-1, and if the DCI is included in other slots, the TCI field reported in the DCI refers to Table 7-2. Alternatively, three Tables 7, such as Table 7-1, Table 7-2, and Table 7-3, may be configured, where the period and period offset of Table 7-1 are set, the period and period offset of Table 7-2 may also be set, and the period and period offset of Table 7-3 are not set. When DCI is included in the slot where Table 7-1 is located, the TCI field in DCI refers to Table 7-1, when DCI is included in the slot where Table 7-2 is located, the TCI field in DCI refers to Table 7-2, when DCI is included in other slots, the TCI field in DCI refers to Table 7-3. In summary, when the interval between DCI and PDSCH is less than a predetermined threshold, the QCL information of PDSCH is obtained according to the TCI indication information indicated in DCI and by referring to the table referred to by the corresponding TCI in the slot where PDSCH is located. Figure 5 shows the time domain patterns corresponding to Tables 7-1 to 7-3. When a PDSCH is included in slot n and the interval between the PDSCH and DCI is less than a predetermined threshold K, the QCL parameters of the DMRS for the PDSCH are obtained in accordance with the TCI information indicated in the DCI and with reference to Table 7-1; when a PDSCH is included in slot n+1 and the interval between the PDSCH and DCI is less than the predetermined threshold K, the QCL parameters of the DMRS for the PDSCH are obtained in accordance with the TCI information indicated in the DCI and with reference to Table 7-2; when a PDSCH is included in slot n and the interval between the PDSCH and DCI is equal to or greater than the predetermined threshold K, the QCL parameters of the DMRS for the PDSCH are obtained in accordance with the TCI information indicated in the DCI and with reference to Table 8.

[0089] Similarly, the table corresponding to the TCI parameter of the AP-CSI-RS is determined according to the relationship between the interval between the DCI and the AP-CSI-RS and a predetermined threshold.

[0090] In an exemplary embodiment, the TCI indication information is used to indicate a QCL relationship between a DMRS group / CSI-RS port group and a DL-RS set, i.e., one TCI index information corresponds to one state, one state includes correspondence relationships between Q DMRS groups and Q DL-RS sets, one DL-RS set includes one or more DL-RSs, each DL-RS is associated with a QCL parameter set, and indicates that a reference signal in the DMRS group / CSI-RS port group and a DL-RS in the DL-RS set associated with the DMRS group / CSI-RS port group satisfy a QCL relationship for the QCL parameter set. Indicates that two reference signals satisfy a QCL relationship for one QCL parameter, and the QCL parameter of one reference signal can be obtained through the QCL parameters of the two reference signals. The QCL parameter includes at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, average gain, or spatial Rx parameter.

[0091] In this exemplary embodiment, the two reference signals are QCLs, and it is indicated that the two reference signals are QCLs for at least the spatial Rx parameters, and whether the two reference signals are QCLs for other QCL parameters is not limited.

[0092] In one exemplary embodiment, a channel may be a signal, i.e., a signal is transmitted on a channel, e.g., a data signal is transmitted on a data channel.

[0093] In one exemplary embodiment, different CCs correspond to different serving cells. The correspondence may be via the cell ID.

[0094] In this embodiment, a method for receiving control signaling is further provided. Figure 9 is a flowchart of a method for transmitting control signaling according to an embodiment of the present application. As shown in Figure 9, the process includes step S902 and step S904, which are described below.

[0095] In step S902, the second information is determined according to the first information. In step S904, a first control signaling is received according to the second information.

[0096] The second information includes at least one of: a number N of bits used in the first control signaling to notify the first transmission parameter; a correspondence mapping table between an index value referenced by the first transmission parameter in the first control signaling and the value of the first transmission parameter; a type of the first transmission parameter notified by a predetermined indication field in the first control signaling; or position information of the bits used in the first control signaling to notify the first transmission parameter; and the first information includes a relationship between a transmission time interval between the first control signaling and the first signal and a predetermined threshold value K, where the transmission time interval is the interval between the first control signaling and the first signal, and N and K are non-negative integers.

[0097] In one embodiment, when the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a first relationship, the value of N includes N1, and when the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship, the value of N includes N2, where N1 and N2 are integers.

[0098] The relationship between N1 and N2 satisfies at least one of the following: N1 is greater than N2; the difference between N1 and N2 is less than or equal to the number of bits occupied by a transmission configuration indication (TCI) field; or the difference between N1 and N2 is less than or equal to the number of bits required to communicate information about the second transmission parameter.

[0099] In one embodiment, when a relationship between a transmission time interval between the first control signaling and the first signal and a predetermined threshold K is a first relationship, the corresponding mapping table is a first corresponding mapping table, and when a relationship between a transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship, the corresponding mapping table is a second mapping table.

[0100] In an embodiment, any one of the first corresponding mapping table, the second corresponding mapping table, the transmission parameter value set 1 and the transmission parameter value set 2 is determined in at least one of the following ways, in the way 1, the content is included in the signaling information to be transmitted, and in the way 2, the rule is pre-agreed by the transmitting end and the receiving end. The transmission parameter value set 1 corresponds to the value set of the first transmission parameter included in the first corresponding mapping table, and the transmission parameter value set 2 corresponds to the value set of the first transmission parameter included in the second corresponding mapping table.

[0101] In one implementation, when the type of the first transmission parameter is TCI, the DL-RS set formed by the DL-RSs associated with the spatial Rx parameters of each state in the first corresponding mapping table includes only one DL-RS; when the type of the first transmission parameter is TCI, the DL-RS set formed by the DL-RSs associated with the spatial Rx parameters of each state in the first corresponding mapping table includes only one DL-RS; For each of the two DL-RSs in the system, the QCL relationship is satisfied for the spatial Rx parameters.

[0102] When the type of the first transmission parameter is TCI, the DL-RSs of the DL-RS set formed by the DL-RSs associated with the spatial Rx parameters of each state in the first corresponding mapping table can be simultaneously received by the first communication node, and when the type of the first transmission parameter is TCI, the DL-RS set formed by the DL-RSs associated with the spatial Rx parameters of each state in the first corresponding mapping table is an empty set. The first communication node is a communication node for receiving at least one of a first signal or a first control signaling.

[0103] In an embodiment, the first transmission parameter type includes one or more transmission parameter types included in the first control signaling, excluding a transmission parameter type of a TCI, or the first transmission parameter type is a transmission parameter of a TCI.

However, in many cases, the former is the preferred implementation form. Based on this understanding, the technical solution of the present application, which substantially or partially contributes to the related art, can be implemented in the form of a software product.

[0135] A case in which the time domain symbol in which the first signal may be located does not include the time domain symbol in which the second signal is located may mean that the first signal is not transmitted and / or received for rate matching in the time domain symbol in which the second signal is located.

[0136] In an embodiment, when the first information is a relationship between a time interval between the first signal and the first control signaling and a predetermined threshold X1, and the second information is a QCL parameter of the first signal, the step of determining the second information according to the first information includes: determining that the QCL parameter of the first signal is identical across different time domain symbols in one time unit; determining that the QCL parameter of the first signal may be different across different time units; that there is a correspondence relationship between the B1 sets of QCL parameters of the first signal and the A time units; determining that the A time units in which the first signal is located are the same across different time domain symbols in one time unit; the QCL parameters of the first signal in each time unit among the A time units are obtained according to the QCL parameters of a CORESET having predetermined characteristics in the time unit closest to each time unit; or, in the A time units in which the first signal is located, the QCL parameters of the first signal in each time unit are determined according to a relationship between a time interval between the first signal and the first control signaling in each time unit and a predetermined threshold value X1, wherein the first signal is in the A time units, A is a natural number greater than 1, and B1 is a non-negative integer less than or equal to A.

[0137] It should be noted that the time unit may be a slot, or a subframe or another time unit.

[0139] The present embodiment will now be described, by way of example, together with specific embodiments. Illustrative embodiment 6 In this embodiment, the base station and the terminal agree that multiple downlink signals in the same time domain symbol satisfy the QCL relationship, i.e., the terminal does not want multiple downlink signals set by the base station in the same time domain symbol to not satisfy the QCL relationship, or the base station and the terminal agree that each two of the multiple downlink signals in the same time domain symbol satisfy the QCL relationship.

[0140] The multiple downlink signals include at least two of a PDSCH data signal, a CORESET, a downlink measurement reference signal, or multiple downlink signals of a CC. For example, the terminal does not want to accept that a downlink signal that does not satisfy a configuration in which the multiple downlink signals do not satisfy a QCL relationship or a configuration in which the multiple downlink signals in the same time domain symbol and the DMRS of the smallest CORESET ID do not satisfy a QCL relationship is in the same time domain symbol.

[0141] As shown in Fig. 6a, the terminal desires that the DMRS of two PDSCHs belonging to different CCs and configured simultaneously should satisfy the QCL relationship. As shown in Fig. 6b, the terminal desires that the PDSCH / DMRS of CC1 and the DMRS of CORESET of CC2 configured simultaneously should satisfy the QCL relationship. As shown in Fig. 6c, the terminal desires that the DMRS of two CORESETs belonging to different CCs configured simultaneously should satisfy the QCL relationship. As shown in Fig. 6d, the terminal desires that the PDSCH / DMRS of CC1 and the DMRS of CORESET of CC2 configured simultaneously should satisfy the QCL relationship.

[0142] 6a-6d show that multiple downlink signals belonging to different CCs need to satisfy the QCL relationship. FIGs. 7a-7d show that multiple downlink signals belonging to the same CC need to satisfy the QCL relationship. FIG. 7e shows that two CSI-RSs of one CC need to satisfy the QCL relationship. Similarly, CSI-RSs from different CCs in the same time domain symbol need to be QCL at least in terms of spatial Rx parameters.

[0143] In one embodiment, the minimum CORESET ID satisfies at least one of the following characteristics: the minimum CORESET ID is the minimum CORESET ID in the time domain symbol closest to the time domain symbol, the minimum CORESET ID is the minimum CORESET ID in the slot closest to the time domain symbol, or the interval between the CORESET and the time domain symbol is less than a predetermined threshold K. In this embodiment, different CCs may correspond to different serving cell IDs.

[0144] Illustrative embodiment 7 In this exemplary embodiment, at least one of the following information is determined according to a relationship between the interval between the first signal and the specified CORESET and a predetermined threshold: the QCL parameters of the first signal, a priority between the QCL parameters of the first signal and the QCL parameters of the second signal (the first signal and the second signal are in the same time domain symbol), a priority between the QCL parameters of the first signal and the QCL parameters of the specified CORESET, or whether a frequency division multiplexing scheme is applicable between the first signal and the second signal in the same time domain symbol.

[0145] In an embodiment, the specified CORESET satisfies at least one of the following characteristics: the CORESET is the CORESET with the smallest CORESET ID in the time domain symbol closest to the downlink signal; the CORESET is the CORESET with the smallest CORESET ID in the slot closest to the downlink signal; in the CORESET, the terminal needs to detect at least one DCI scheduling the downlink signal or channel; the CORESET does not include information regarding control signaling scheduling the first signal; the CORESET includes information regarding control signaling scheduling the second signal; or the CORESET is associated with at least one dedicated search space.

[0146] In an embodiment, if 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 CORESET, and if the interval between the first signal and the minimum CORESET ID is equal to or greater than the predetermined threshold, the QCL parameters of the first signal are obtained according to the QCL parameters set in the configuration information of the downlink signal.

[0147] In one embodiment, when the interval between the first signal and CORESET is less than a predetermined threshold, the priority of the QCL parameters of the first signal is higher than the priority of the QCL parameters of the second signal, and when the interval between the first signal and CORESET is equal to or greater than the predetermined threshold, the priority of the QCL parameters of the first signal is lower than the priority of the QCL parameters of the second signal.

[0148] In one embodiment, if the interval between the first signal and CORESET is less than a predetermined threshold, frequency division multiplexing cannot be applied between the first signal and the second signal, and if the interval between the first signal and CORESET is equal to or greater than the predetermined threshold, frequency division multiplexing can be applied between the first signal and the second signal.

[0149] The QCL parameters include at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, average gain, or spatial Rx parameters.

[0150] In an embodiment, the first signal includes at least one of a downlink measurement reference signal, a downlink synchronization signal, a downlink demodulation reference signal, a downlink data channel signal, or a downlink control channel signal.

[0151] In an embodiment, the second signal includes at least one of a downlink measurement reference signal, a downlink synchronization signal, a downlink demodulation reference signal, a downlink data channel signal, or a downlink control channel signal.

[0152] In one embodiment, the predetermined threshold is equal to a second predetermined threshold, and the QCL parameter of the second signal is determined according to a relationship between the interval between the second signal and the control information scheduling the second signal and the second predetermined threshold.

[0153] In one embodiment, the relevant NR specifies that if the interval between DCI and PDSCH is less than a predetermined threshold K, the PDSCH is received using the spatial Rx parameters of the smallest CORESET ID in the nearest slot. When the terminal caches the PDSCH, the DCI is not decoded, so it is necessary to cache the PDSCH using a known beam. The PDSCH is stored in the K time domain slots after the DCI. In this case, the terminal needs to cache the PDSCH in a time window of K time domain symbols after the DCI using the beam with the smallest CORESET ID. However, it is possible that these potential PDSCHs do not actually exist and 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 parameters of the periodic CSI-RS are different from the spatial Rx parameters of the PDSCH that the terminal needs to cache, it is necessary to determine the priority between the spatial Rx parameters of the periodic CSI-RS and the spatial Rx parameters of the PDSCH that the terminal needs to cache.

[0154] In method 1, the base station and the terminal agree that at least one of the spatial Rx parameters of the downlink signal or the spatial Rx parameters of the downlink channel in this time window is determined based on the spatial Rx parameters of the CORESET having the minimum CORESET ID, and other QCL parameters of at least one of the downlink signals or channels are also determined based on the minimum CORESET ID, or the other QCL parameters are obtained according to the configuration information of the downlink signal or channel, for example, according to the configuration information of the QCL parameters in the configuration information of the periodic CSI-RS.

[0155] In method 2, the base station and the terminal agree that if the interval between the periodic CSI-RS and the CORESET with the smallest CORESET ID in the nearest slot is less than a predetermined threshold K, the priority of the QCL parameter, which is at least the spatial Rx parameter, of the periodic CSI-RS is higher than the priority of the spatial Rx parameter of a potential PDSCH in the same time domain symbol, and if the interval between the periodic CSI-RS and the CORESET with the smallest CORESET ID in the nearest slot is equal to or greater than the predetermined threshold K, the priority of the spatial Rx parameter of the PDSCH in the same time domain symbol is higher than the priority of the spatial Rx parameter of the CSI-RS in the same time domain symbol.

[0156] As shown in FIG2, the CORESET with the smallest CORESET ID in the slot closest to the periodic CSI-RS in slot n is CORESET0 in slot n. If the PDSCH and CSI-RS in slot n are in the same time domain symbol, the beam of the CSI-RS is used to receive the CSI-RS and the PDSCH, i.e., in this case, the priority of the spatial Rx parameters of the PDSCH is lower than the priority of the spatial Rx parameters of the periodic CSI-RS. In this case, if there is no symbol of the periodic CSI-RS in slot n, in a certain manner, the number of beam switching by the terminal in slot n is reduced by receiving the PDSCH using the spatial Rx parameters of the periodic CSI-RS, or the terminal and the base station agree to receive the PDSCH using the beam of the CORESET closest to the PDSCH, as shown in FIG3, if there is no time domain symbol of the CSI-RS in slot n.

[0157] The smallest CORESET ID in the slots closest to the periodic CSI-RS in slot n+2 is still CORESET0 in slot n (the terminal does not need to detect CORESET in slots n+1 and n+2). In this case, the interval between the periodic CSI-RS in slot n+2 and CORESET0 is greater than a predetermined threshold, and if the PDSCH and CSI-RS are in the same time domain symbol in slot n+2, the PDSCH and CSI-RS are received using the beam of the PDSCH. That is, in this case, the priority of the spatial Rx parameters of the PDSCH is higher than the priority of the spatial Rx parameters of the periodic CSI-RS. Alternatively, in slot n+2, the reception beam of the PDSCH and the reception beam of the CSI-RS are received using the beam of the PDSCH. If there is a conflict between the beams (PDSCH and CSI-RS are in the same time domain symbol), the measurement of CSI-RS is abandoned. In slot n, if the terminal needs to cache the PDSCH scheduled by CORESET0, the PDSCH may not exist because the DCI is not decoded, in which case the periodic CSI-RS needs to be received with priority. In slot n+2, the terminal has already decoded the DCI corresponding to the PDSCH that the terminal needs to cache, in which case the terminal determines that the PDSCH has already been scheduled by the base station.

[0158] Illustrative embodiment 8 In this embodiment, the second information is determined according to the first information, and the second information includes at least one of the following information: a QCL parameter of the first signal, whether a control channel is detected in the first signal, whether the first signal is received, or a time domain symbol position where the first signal may be located, and the first information includes information whether the second signal is present in a predetermined time window after a specified CORESET.

[0159] In an embodiment, the designated CORESET satisfies at least one of the following characteristics: the CORESET is the CORESET with the smallest CORESET ID in the time domain symbol closest to the second signal; the designated CORESET is the CORESET with the smallest CORESET ID in the slot closest to the second signal; in the CORESET, the terminal needs to detect at least one DCI scheduling downlink signal or channel; the CORESET is the CORESET with the smallest CORESET ID in the time domain symbol closest to the first signal; or the designated CORESET is the CORESET with the smallest CORESET ID in the slot closest to the first signal.

[0160] In an embodiment, the first signal includes at least one of the following signals: an aperiodic downlink measurement reference signal, a downlink data channel signal scheduled by physical layer dynamic control signaling, a downlink signal scheduled by physical layer dynamic control signaling, or a downlink physical control channel signal.

[0161] In an embodiment, the second signal satisfies at least one of the following characteristics: the second signal is a previously scheduled signal; the second signal is a periodic downlink measurement reference signal; the second signal is an aperiodic downlink measurement reference signal, and an interval between the DCI for scheduling the aperiodic measurement reference signal and the aperiodic measurement reference signal is equal to or greater than a predetermined threshold; the second signal is a semi-continuous PDSCH, and an interval between the DCI for activating a semi-persistent scheduling PDSCH (SPS-PDSCH) and the SPS-PDSCH is equal to or greater than a predetermined threshold; or the second signal is a dynamically scheduled PDSCH, and an interval between the DCI for dynamically scheduling the PDSCH and the PDSCH is equal to or greater than a predetermined threshold.

[0162] In one embodiment, if a second signal is present in a predetermined time window after the specified CORESET, the QCL parameters of the first signal are obtained according to the QCL parameters of the second signal, and if the second signal is not present in the predetermined time window after the specified CORESET, the QCL parameters of the first signal are not obtained according to the QCL parameters of the second signal.

[0163] In one embodiment, in the time domain symbol in which the second signal is located, Agree with the second communication node that no signal is present.

[0164] In one embodiment, it is agreed with the second communication node that no control channel is detected in the first signal in the time domain symbol in which the second signal is located.

[0165] In an embodiment, the spatial Rx parameters of the second signal and the spatial Rx parameters of the first signal are different, or the spatial filter corresponding to the spatial Rx parameters of the second signal and the spatial filter corresponding to the spatial Rx parameters of the first signal cannot be generated simultaneously by the first communication node.

[0166] In one embodiment, the second signal and the first signal belong to different CCs. In an embodiment, as shown in FIG. 1a, in slot n, the base station schedules PDSCH1 for the terminal, and the interval between the DCI that schedules PDSCH1 (in FIG. 1a, the DCI is in CORESET1) and PDSCH1 is greater than a predetermined threshold K, so in slot n, the terminal certainly knows that the base station scheduled PDSCH1 in slot n, and thus the QCL parameter of PDSCH1 can be obtained through the information indicated in the DCI that scheduled PDSCH1. In slot n, the terminal further needs to continue to detect at least one of CORESET0 or CORESET2. The DCI in CORESET0 or CORESET2 can be used to schedule PDSCH2 for the terminal. For example, PDSCH2 and PDSCH1 may be in different CCs. Because while potential PDSCH2 is received, the terminal has not decoded DCI scheduling PDSCH2, and according to the rule, potential PDSCH2 should be received using the beam of the smallest CORESET ID in all CCs of slot n, for example, PDSCH2 is received using the beam of CORESET0. If the receiving beam dynamically indicated (through the spatial Rx parameters indicated in DCI) of PDSCH1 and the beam of CORESET0 are different, it is necessary to determine the priority between the spatial Rx parameters of PDSCH1 and the spatial Rx parameters of PDSCH2. Since PDSCH1 is determined to be scheduled and PDSCH2 may not exist, the beam of PDSCH1 is preferentially used for receiving potential PDSCH1 and PDSCH2.

[0167] As shown in FIG. 1b, in slot n, the base station schedules an aperiodic measurement reference signal (CSI-RS) for the terminal, and the interval between the DCI that schedules the aperiodic CSI-RS and the aperiodic measurement reference signal is greater than a predetermined threshold K. In slot n, the terminal also needs to detect CORESET0. CORESET0 can be used to schedule a PDSCH for the terminal in slot n, so when the PDSCH and CSI-RS in slot n are in the same time domain symbol, it is necessary to determine the priority between the QCL parameter of the PDSCH and the QCL parameter of the CSI-RS. Similarly, since it is determined that the aperiodic measurement reference signal is scheduled, the terminal receives the CSI-RS and the potential PDSCH using the aperiodic measurement reference signal at least in the time domain symbol where the CSI-RS is located. If the time-domain symbol of the aperiodic measurement reference signal is not present in slot n, the QCL parameters of the potential PDSCH can be obtained using the QCL parameters of the CORESET with the smallest CORESET ID in slot n, or it is defined that in slot n, the PDSCH is received using the receive beam of the aperiodic CSI-RS in the time-domain symbol in which the potential PDSCH is located.

[0168] From Figures 1a and 1b, the relationship between the PDSCH and the DCI that schedules the PDSCH can be seen. It can be seen that even if the interval between the first and second CORESETs is less than a predetermined threshold K, it is not necessarily necessary to obtain the QCL parameters of the PDSCH using the QCL parameters of the CORESET with the smallest CORESET ID closest to the PDSCH, and it is also necessary to consider whether a second signal exists in the time domain symbol where the PDSCH is located. If a second signal exists in the time domain symbol where the PDSCH is located, at least the spatial Rx parameters of the first signal are determined according to the spatial Rx parameters of the second signal, and if a second signal does not exist in the time domain symbol where the PDSCH is located, the QCL parameters are obtained according to the QCL parameters of the CORESET with the smallest CORESET ID closest to the PDSCH, and the QCL parameters include at least the spatial Rx parameters.

[0169] As shown in Figure 1c, when the interval between the PDSCH and the DCI scheduling the PDSCH is less than a predetermined threshold K, at least the spatial Rx parameters of the PDSCH are obtained according to the spatial Rx parameters of the minimum CORESET ID in the time domain symbol closest to the PDSCH (i.e., the spatial Rx parameters of the PDSCH are obtained according to the spatial Rx parameters of CORESET1), rather than according to the spatial Rx parameters of the CORESET with the minimum CORESET ID in the slot closest to the PDSCH (i.e., the spatial Rx parameters of the PDSCH are not obtained according to the spatial Rx parameters of CORESET0).

[0170] As shown in FIG. 1d, if the interval between the PDSCH and the DCI scheduling the PDSCH is less than a predetermined threshold K, the PDSCH needs to be received using the receive beam of CORESET in the slot closest to the PDSCH, and the potential PDSCH can be stored in any time domain symbol in the slot. Thus, in the time domain symbol in which CORESET1 is located, the potential PDSCH and CORESET1 need to be received simultaneously. If the receive beam of CORESET1 and the receive beam of CORESET0 are different, or if the terminal cannot generate these two receive beams simultaneously, it is necessary to determine the priority between these two receive beams. In one scheme, it is specified that the potential PDSCH in CORESET1 and CORESET1 are QCL, at least for the spatial Rx parameters. In another scheme, it is specified that there is no PDSCH in CORESET1 if the interval between the PDSCH and the DCI scheduling the PDSCH is less than a predetermined threshold K.

[0171] As shown in FIG. 1e, in this case, in a slot, the terminal needs to detect a CORESET in multiple time domain symbols and cache a potential PDSCH, which means that the interval between the PDSCH and the DCI scheduling the PDSCH is less than a predetermined threshold K. In this case, the QCL parameter of the PDSCH is not obtained according to the QCL parameter of the CORESET with the smallest CORESET ID in the slot closest to the PDSCH (as shown in FIG. 1e, the QCL parameter of the PDSCH is not obtained according to the QCL parameter of CORESET0), but according to the QCL parameter of the CORESET with the smallest CORESET ID of the first three time domain symbols in the slot closest to the PDSCH (as shown in FIG. 1e, the QCL parameter of the PDSCH is obtained according to the QCL parameter of CORESET1).

[0172] As shown in FIG. 1f, in this case, it is determined that the base station schedules a PDSCH for the terminal in slot n, i.e., in this case, the interval between the DCI for scheduling the PDSCH and the PDSCH is greater than a predetermined threshold K, and in slot n, the base station further sets a CORESET that needs to be detected for the terminal somewhat statically. In this case, in a certain scheme, the spatial Rx parameters of the CORESET and the spatial Rx of the PDSCH are calculated in the time domain symbol where the PDSCH is located. If the spatial Rx parameters of the PDSCH and CORESET are different, the terminal does not need to receive and detect CORESET in this time domain symbol, or the terminal and the base station agree that in this case, the PDSCH of the PDSCH and CORESET in the same time domain symbol as the PDSCH are QCL for at least the spatial Rx parameters. Alternatively, the terminal and the base station agree to receive the PDSCH and CORESET via a receive beam corresponding to the spatial Rx parameters of CORESET when the PDSCH and CORESET are in the same time domain symbol and the receive beam corresponding to the spatial Rx parameters of the PDSCH and the receive beam corresponding to the spatial Rx parameters of CORESET are different.

[0173] Illustrative embodiment 9 In this embodiment, a method for acquiring QCL parameters of a PDSCH when the PDSCH occupies a plurality of slots will be described.

[0174] First, a problem is how to obtain the interval between the PDSCH and the DCI that schedules the PDSCH, which includes the following two obtaining methods:

[0175] In the time interval acquisition method 1, the acquisition method of the QCL parameters of the PDSCH is obtained according to one time interval between the starting symbol position of the PDSCH in the first slot of the A slots occupied by the PDSCH and the DCI, and a predetermined threshold value X1 (K, etc., and of course, the present application does not exclude the case where X1 and K are different). For example, if this time interval is less than the predetermined threshold value X1, the QCL parameters of the PDSCH are acquired according to the QCL parameters of a specified CORESET (such as the CORESET with the smallest CORESET ID in the slot) in the slot closest to the PDSCH, and if this time interval is equal to or greater than the predetermined threshold value X1, the QCL parameters of the PDSCH are acquired according to the information indicated by the DCI, as shown in Figure 4b.

[0176] In the time interval acquisition method 2, the acquisition method of the QCL parameters of the PDSCH in each slot is obtained according to 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 a predetermined threshold value X1 (K, etc., and of course, the present application does not exclude the case where X1 and K are different). For example, if the interval between the PDSCH and the DCI in each of the first A1 slots is less than the predetermined threshold value X1, the QCL parameters of the PDSCH in the A1 slots are acquired according to the QCL parameters of a specified CORESET (such as the CORESET with the smallest CORESET ID in the slot) in the slot closest to the PDSCH, and if the interval between the PDSCH and the DCI in each of the last A2 slots is equal to or greater than the predetermined threshold value X1, the QCL parameters of the PDSCH in the A1 slots are acquired according to the information indicated in the DCI, as shown in Figure 4a.

[0177] Another issue is that it is understood that there are two ways of acquisition, which is done according to the QCL parameters of the CORESET with predefined characteristics in the slots closest to the PDSCH.

[0178] In the QCL parameter acquisition method 1, the QCL parameters of the PDSCH in the A slots are acquired according to the QCL parameters of the CORESET with the smallest CORESET ID in the slot closest to the first slot among the A slots occupied by the PDSCH. The acquisition method of the QCL parameters of the PDSCH in the A slots is not changed, or the QCL parameters of the PDSCH in the A slots are left unchanged.

[0179] In the QCL parameter acquisition method 2, the QCL parameters of the PDSCH in each slot are acquired according to the QCL parameters of the CORESET with the smallest CORESET ID in each slot that is closest to each slot among the A slots occupied by the PDSCH. The acquisition methods of the QCL parameters of the PDSCH in the A slots do not need to be the same, and the QCL parameters of the PDSCH in the A slots may change.

[0180] Time interval acquisition methods 1 and 2 may optionally cooperate with QCL parameter acquisition methods 1 and 2.

[0181] In an embodiment, when time interval acquisition method 1 and QCL parameter acquisition method 1 are adopted, as shown in FIG. 4c, when the time interval between the first slot of the three slots occupied by the PDSCH and the DCI is less than a predetermined threshold K, the QCL parameters of the PDSCH in the three slots are acquired according to the QCL parameters of the CORESET with the smallest CORESET ID in the slot closest to the first slot (i.e., the QCL parameters of CORESET0 in slot n), and the QCL parameters of the PDSCH in the three slots are left unchanged.

[0182] When the time interval acquisition method 1 and the QCL parameter acquisition method 2 are adopted, as shown in FIG. 4b, when the time interval between the first slot of the three slots occupied by the PDSCH and the DCI is less than a predetermined threshold K, the QCL parameters of the PDSCH in the three slots are acquired according to the QCL parameters of the CORESET with the smallest CORESET ID in the slot closest to each slot, and the QCL parameters of the PDSCH in the three slots may be different or identical.

[0183] When the time interval acquisition method 2 and the QCL parameter acquisition method 1 are adopted, as shown in Fig. 4d, it is determined whether the QCL parameters of each of the three slots occupied by the PDSCH are acquired according to the CORESET or according to the information indicated in the DCI according to the relationship between the time interval between each of the three slots occupied by the PDSCH and the DCI and the predetermined threshold K. If the interval between each of the multiple slots of the PDSCH and the DCI is less than the threshold K, the QCL parameters of the PDSCH in the multiple slots (i.e., slot n and slot n+1 in Fig. 4d) remain unchanged, and the QCL parameters of the PDSCH are acquired according to the QCL parameters of the CORESET with the smallest CORESET ID in the slot closest to the first slot of the multiple slots, and if the interval between the PDSCH and the DCI in slot n+2 is greater than K, the QCL parameters of the PDSCH in slot n+2 are acquired according to the information indicated in the DCI.

[0184] When the time interval acquisition method 2 and the QCL parameter acquisition method 2 are adopted, as shown in FIG. 4a, it is determined whether the QCL parameters of each of the three slots occupied by the PDSCH are acquired according to the CORESET or according to the information indicated by the DCI according to the relationship between the time interval between each of the three slots occupied by the PDSCH and the DCI and the predetermined threshold K. If the interval between each of the multiple slots of the PDSCH and the DCI is less than the threshold K, the QCL parameters of the PDSCH in each of the multiple slots (i.e., slot n and slot n+1 in FIG. 4d) are acquired according to the QCL parameters of the CORESET with the smallest CORESET ID in the respective slots closest to each slot, and if the interval between the PDSCH and the DCI in slot n+2 is greater than K, the QCL parameters of the PDSCH in slot n+2 are acquired according to the information indicated in the DCI. Determine the interval between the PDSCH and CORESET0 scheduling in each of the three slots. If the interval is less than K, the QCL parameters of the PDSCH are obtained using the QCL parameters of the CORESET with the smallest CORESET ID in each slot that is closest to each slot. If the interval is greater than K, the QCL parameters of the PDSCH are obtained using the QCL parameters indicated in the DCI. As shown in FIG. 4a, in slot n, the PDSCH is received using the beam of CORESET0 in slot n, in slot n+1, the PDSCH is received using the beam of CORESET1 in slot n+1, and in slot n+2, the receiving beam of slot n+2 is determined using the QCL parameters indicated in the DCI transmitted in CORESET0 in slot n. The reason is that in K time domain symbols, the terminal needs to cache the PDSCH without decoding the DCI, and it is possible to schedule data for the terminal in CORESET0 in slot n and CORESET1 in slot n+1. Before the terminal does not detect the DCI, the terminal needs to cache at least one of CORESET0 and CORESET1 of the scheduled PDSCH in slot n+1. When the receiving capability of the terminal is limited, for example, the terminal may generate only one receiving beam, and obtain the QCL parameters of the PDSCH of each slot in the range where the interval between the DCI and the PDSCH is less than a predetermined threshold K by using a CORESET having the smallest CORESET ID of the slot closest to the PDSCH in each slot.

[0185] In particular, if the spacing between the PDSCH and the DCI is greater than 1, whether the A2 slots correspond to one set of QCL parameters (as shown in FIG. 4e) or whether each slot among the A2 slots corresponds to a respective set of QCL parameters (as shown in FIG. 4f) is further agreed upon by the base station and the terminal or indicated by the base station via signaling information.

[0186] The combination of the specific time interval acquisition method and the specific QCL parameter acquisition method to be adopted may be agreed upon between the terminal and the base station, or may be notified by the base station through signaling information.

[0187] As shown in Figures 4a to 4d, K indicates 26 time domain symbols, and in slot n, the PDSCH scheduled by CORESET0 spans three slots: {slot n, slot n+1, slot n+2}.

[0188] In FIG. 4f, when the interval between the PDSCH and the DCI is greater than two slots of a predetermined threshold K, the DCI notifies different QCL parameters for different slots, so that the DCI needs to set the QCL parameters corresponding to each slot. Of course, this embodiment does not preclude the base station to set the QCL parameters of one slot of the multiple slots for multiple slots of the DCI (for example, set the QCL parameters of slot n+2, i.e. set the QCL parameters of the first slot), and set the QCL parameters of other slots by higher layer signaling, or obtain the QCL parameters of other slots according to the QCL parameters set by the DCI. For example, adopt a polling scheme in multiple slots. For example, there are only two sets of QCL parameters notified by at least one of the DCI or higher layer signaling, the PDSCH occupies four slots, and two sets of QCL parameters are polled in the four slots. In FIG. 4a to FIG. 4f, different QCL parameters correspond to different beams. The higher layer signaling may be an RRC signaling or a MAC-CE command. The higher layer signaling may be an higher layer signaling used to signal a candidate TCI state in the DCI. For example, if the TCI of slot n+2 signaled by the DCI is TCI state 2 (the TCI field signaled in the DCI contains 3 bits, corresponding to 8 active TCI states), the TCI state of the PDSCH in slot n+3 corresponds to TCI state 3.

[0189] In this exemplary embodiment, data may be transmitted repeatedly in multiple slots occupied by one PDSCH, or different data may be transmitted in multiple slots.

[0190] Illustrative embodiment 10 In this embodiment, one state in the TCI field signaled in the DCI corresponds to multiple relationships, where different relationships correspond to different time units or different sets of time units occupied by the PDSCH, where each relationship corresponds to one of the time units or one set of time units occupied by the PDSCH, where one relationship includes relationships between Z DMRS groups and Z RS sets, where the Z DMRS groups have a one-to-one correspondence with the Z RS sets, and where the DMRS group and the corresponding RS set satisfy a QCL relationship for the QCL parameter in the corresponding time unit or set of time units.

[0191] Illustrative embodiment 11 In this embodiment, if the QCL parameter of the PDSCH / AP-CSI-RS is obtained according to the QCL parameter of the CORESET with the smallest CORESET ID in the slot closest to the PDSCH / AP-CSI-RS, it is further evident that the CORESET satisfies at least one of the following characteristics:

[0192] The CORESET with the minimum CORESET ID is the minimum CORESET among all CORESETs that a terminal needs to detect included in all CCs of the time unit. It is a CORESET with an ID.

[0193] The CORESET with the minimum CORESET ID is the CORESET with the minimum CORESET ID among all CORESETs that are included in the corresponding primary cell (PCell) of the time unit and that need to be detected by a terminal.

[0194] The CORESET with the minimum CORESET ID is the CORESET with the minimum CORESET ID among all CORESETs that need to be detected by a terminal included in a serving cell in which a corresponding PDSCH is located in the time unit.

[0195] The CORESET with the minimum CORESET ID is the CORESET with the minimum CORESET ID among all CORESETs that need to be detected by a terminal included in a serving cell in which a corresponding DCI that schedules a PDSCH is located in a time unit.

[0196] The CORESET with the minimum CORESET ID is the CORESET with the minimum CC ( The CORESET with the smallest CORESET ID is the CORESET with the smallest CORESET ID among all CORESETs that a terminal needs to detect and that are included in a serving cell located in the time unit.

[0197] The CORESET with the minimum CORESET ID is the CORESET with the minimum CORESET ID among all CORESETs that are required to be detected by terminals included in a predetermined CC group of a time unit.

[0198] Illustrative embodiment 12 In this embodiment, the QCL parameters of one CORESET are associated with whether or not the first communication node detects a beam recovery response signal.

[0199] In an embodiment, the base station sets one CORESET for the terminal. If the terminal does not detect a beam recovery response signal, the base station notifies the terminal of the QCL parameters of CORESET by signaling. If the terminal needs to detect a beam recovery response signal (for example, the terminal detects the beam recovery response signal of the base station in CORESET in four slots after the terminal transmits a beam recovery request signal to the base station, and if the predetermined time window is exceeded and the terminal cannot detect the beam recovery response signal transmitted from the base station, the terminal stops detecting the beam recovery request signal in CORESET), the QCL parameters of CORESET are obtained according to the beam discovered by the terminal in the beam recovery request signal transmitted by the terminal. As shown in FIG. 8a, in the T1 period, the terminal obtains the QCL parameters of CORESET1 according to the signaling information notified by the base station. In the T2 period, the terminal starts to detect the beam recovery request response signal transmitted by the base station in CORESET1. The QCL parameters of CORESET1 are obtained according to the reference signal indication information "q new " and "q new " indicates the reference signal indication information selected by the terminal in the RS set (i.e., indicates the beam newly selected by the terminal). In the T3 period, the QCL parameters of CORESET1 are obtained according to the signaling information transmitted by the base station, and in the T1 and T3 periods, the signaling information of the QCL parameters for CORESET1 transmitted by the base station to the terminal may be different signaling information, i.e., the base station may update the QCL parameters of CORESET1 in the T2 period according to the signaling information. The new beam discovered by the terminal in the beam recovery request signal transmitted by the terminal is obtained through the reference signal indication information transmitted by the terminal, and the reference signal indication information indicates the reference signal selected by the terminal in the RS set. The reference signal includes at least one of a measurement reference signal or a synchronization reference signal.

[0200] Illustrative embodiment 13 In this embodiment, the physical layer dynamic control signaling that schedules the aperiodic measurement reference signal may be after the aperiodic measurement reference signal.

[0201] In one embodiment, the aperiodic measurement reference signal and the physical layer dynamic control signaling are in the same time units.

[0202] As shown in Figure 8b, the starting time-domain symbol in which the DCI scheduling the aperiodic measurement reference signal is located is after the aperiodic measurement reference signal. As shown in Figure 8c, a part of the time-domain symbol in which the DCI scheduling the aperiodic measurement reference signal is located is after the aperiodic measurement reference signal, i.e., for example, the DCI is three time-domain symbols and the CSI-RS is in the first symbol of the time-domain symbols in which the DCI is located.

[0203] In an exemplary embodiment, the TCI indication information is used to indicate a QCL relationship between a DMRS group / CSI-RS port group and a DL-RS set, i.e., one TCI index information corresponds to one state, one state includes correspondence relationships between Q DMRS groups and Q DL-RS sets, one DL-RS set includes one or more DL-RSs, each DL-RS is associated with one QCL parameter set, and indicates that a reference signal in the DMRS group / CSI-RS port group and one DL-RS in the DL-RS set associated with the DMRS group / CSI-RS port group satisfy a QCL relationship for the QCL parameter set; indicates that two reference signals satisfy a QCL relationship for one QCL parameter, and the QCL parameter of one reference signal can be obtained through the QCL parameters of the two reference signals. The QCL parameters include at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, average gain, or spatial Rx parameters.

[0204] In this exemplary embodiment, the two reference signals are QCLs, and it is indicated that the two reference signals are QCLs with respect to at least the spatial Rx parameters, and there is no limitation as to whether the two reference signals are QCLs with respect to other QCL parameters.

[0205] In one exemplary embodiment, a channel may be a signal, i.e., a signal is transmitted in a channel, e.g., a data signal is transmitted in a data channel.

[0206] In one exemplary embodiment, different CCs can be associated through different serving cell IDs.

[0207] Illustrative embodiment 14 In this exemplary embodiment, the terminal does not want to receive a configuration that satisfies the characteristic that the PDSCH and CSI-RS in the same time symbol do not satisfy the QCL relationship for spatial Rx parameters.

[0208] In one embodiment, the spacing between the PDSCH and the control signaling scheduling the PDSCH is less than a predetermined threshold K.

[0209] From the description of the above implementation forms, it will be clear to those skilled in the art that the methods of the above embodiments may be implemented by software and a necessary general-purpose hardware platform, or of course by hardware. However, in many cases, the former is a preferred implementation form. Based on this understanding, the technical solutions in this application, or the parts that contribute to the related art, may be implemented in the form of a software product. The computer software product is stored in a storage medium (such as a ROM / RAM, a magnetic disk, or an optical disk) and includes some instructions that enable a terminal device (which may be a mobile phone, a computer, a server, or a network device) to execute the methods of each embodiment of the present application.

[0210] EMBODIMENT 3 In this embodiment, a device for transmitting control signaling is further provided. The device is configured to realize the above embodiment and preferred implementation. The contents already described will not be repeated. The term "module" used below may be software, hardware, or a combination thereof that can realize a predetermined function. The device of the embodiment described below is preferably realized by software, but may also be realized by hardware, and may also be realized by a combination of software and hardware.

[0211] 11 is a block diagram showing the structure of an apparatus for transmitting control signaling according to an embodiment of the present application. The apparatus is applied to a first communication node. As shown in FIG. 11, the apparatus includes: a first determining module 112 and a first sending module 114.

[0212] 1) The first determination module 112 is configured to determine second information according to the first information.

[0213] The second information includes at least one of: a number N of bits used to notify the first transmission parameter in the first control signaling, a correspondence mapping table between an index value referenced by the first transmission parameter in the first control signaling and a value of the first transmission parameter, a type of the first transmission parameter notified by a predetermined indication field in the first control signaling, or position information of the bits used to notify the first transmission parameter in the first control signaling, and the first information includes a relationship between a transmission time interval between the first control signaling and the first signal and a predetermined threshold value K, where N and K are non-negative integers.

[0214] 2) The first transmitting module 114 is configured to transmit a first control signaling.

[0215] The apparatus shown in Fig. 11 determines the second information according to the first information, where the second information includes at least one of: a number N of bits used to notify the first transmission parameter in the first control signaling, a correspondence mapping table between an index value referenced by the first transmission parameter in the first control signaling and a value of the first transmission parameter, a type of the first transmission parameter notified by a predetermined indication field in the first control signaling, or position information of the bit used to notify the first transmission parameter in the first control signaling, where the first information includes a relationship between a transmission time interval between the first control signaling and the first signal and a predetermined threshold value K, where N and K are non-negative integers, and the first control signaling is transmitted. That is, the format of the control signaling is determined using the second information, and then the new control signaling is transmitted. In this way, the deficiency of the related art in that some of the resources in the related control signaling are idle and therefore resource utilization is relatively low is overcome, and a technical effect of improving resource utilization of the control signaling is achieved.

[0216] In one embodiment, when the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a first relationship, the value of N includes N1, and when the relationship between the transmission time interval between the first control signaling and the first signal and the predetermined threshold K is a second relationship, the value of N includes N2, where N1 and N2 are integers.

[0217] The relationship between N1 and N2 satisfies at least one of the following: N1 is greater than N2; the difference between N1 and N2 is less than or equal to the number of bits occupied by the TCI field; or the difference between N1 and N2 is less than or equal to the number of bits required to signal information about the second transmission parameter.
