Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In order to clearly describe the technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if "first", "second", and the like words are used to distinguish the same item or similar items having substantially the same function and effect, those skilled in the art will understand that the "first", "second", and the like words do not limit the number and execution order.

In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "three kinds generally indicates that the front-rear association object is an or relationship.

The term "plurality" in embodiments of the present invention means two or more, and other adjectives are similar.

Furthermore, it should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

When the control information is repeatedly transmitted in 2 or more symbols or slots in a time division multiplexing manner, the terminal may detect the control information or the control channel at 2 or more monitoring occasions, that is, there are 2 or more receiving positions of the control information. In this case, if the transmission parameters of the PDSCH, physical Up-shared channel (Physical Up LINK SHARED CHANNEL, PUSCH), or aperiodic channel state Information reference signal (CHANNEL STATE Information-REFERENCE SIGNAL, CSI-RS) scheduled or indicated by the control Information and the content of the control Information are determined according to the method in the related art, there may be cases where the transmission parameters determined according to 2 or more control Information are different, and thus the terminal device cannot determine the transmission parameters used by the network device when transmitting the Physical channel Hu Wuli signal.

For example, as shown in fig. 1, the terminal device detects PDCCH1 and PDCCH2 in slot n and slot n+1, respectively, and downlink control information (Downlink Control Information, DCI) carried by 2 PDCCHs is the same, the slot offset k0=1 in the time domain resource allocation domain (Time domain resource assignment, TDRA domain), the transmission slot of the PDSCH determined by the position of PDCCH1 and K0 is slot n+1, and the transmission slot of the PDSCH determined by the position of PDCCH2 and K0 is slot n+2. Therefore, the terminal cannot determine from which PDCCH is located a transmission slot of the PDSCH. If the base station and the terminal determine PDSCH according to different PDCCH locations, for example, the base station determines a transmission time slot of the scheduled PDSCH according to PDCCH1 location and k0=1, i.e. transmits PDSCH in slot n+1, and the terminal detects PDSCH according to PDCCH2 location and k0=1, i.e. detects PDSCH in slot n+2, which may cause the terminal device to erroneously determine the location of PDSCH, thereby causing PDSCH transmission failure.

For another example, as shown in fig. 2, it is assumed that the terminal device detects PDCCH1 and PDCCH2 on symbol 3 and symbol 4, respectively, and DCI carried by 2 PDCCHs is the same, the starting symbol s=3 of PDSCH indicated by TDRA field, the starting symbol of PDSCH determined by the position of PDCCH1 and S is symbol 6, and the starting symbol of PDSCH determined by the position of PDCCH2 and S is symbol 7. Similarly, the terminal cannot determine from which PDCCH the starting symbol of PDSCH should be determined. If the base station and the terminal determine the transmission parameters of the PDSCH according to different PDCCHs, the terminal device may determine the position of the PDSCH by mistake, which may cause PDSCH transmission failure.

For another example, for aperiodic CSI-RS transmission, parameter aperiodicTriggeringOffset is configured by higher layer signaling, representing an offset between a slot containing DCI and an aperiodic CSI-RS resource set transmission slot. If the two DCIs are identical in content and transmitted in different time slots, and the offset value of the higher layer configuration is fixed, this may result in a case where the aperiodic CSI-RS transmission time slots determined according to the two DCIs are not identical. Similarly, the terminal cannot determine from which DCI the transmission slot of the aperiodic CSI-RS should be determined. If the base station and the terminal determine the transmission time slot of the aperiodic CSI-RS according to different DCIs, the terminal device may determine the position of the aperiodic CSI-RS by mistake, which may further result in inaccurate CSI measurement results.

Aiming at the situation that the control information is repeatedly transmitted in a time division multiplexing mode, the embodiment of the invention provides a control information transmission method, and the transmission parameters of a physical channel or a physical signal determined by terminal equipment according to one or more control information and the transmission parameters used by a base station are the same through a network equipment side configuration or indication mode. That is, the transmission parameters of the physical channels or the physical signals, which the terminal desires to determine according to the two or more control information transmitted from the network device side, are the same, or the transmission parameters of the physical channels or the physical signals, which the terminal does not desire to determine according to the two or more control information transmitted from the network device side, are different, or the terminal determines a set of transmission parameters of the physical channels or the physical signals according to the two or more control information transmitted from the network device side. The determined transmission parameters of the physical channel or physical signal may be transmission parameters (transmission time slot and start symbol, etc.) of the physical channel or physical signal. The specific process is as follows:

As shown in fig. 3, a flowchart of steps of a control information transmission method applied to a terminal in an embodiment of the present invention is shown, where the method includes the following steps:

step 301: n pieces of control information transmitted by the network device in one scheduling unit are received.

Specifically, when the control information is transmitted in a time division multiplexing manner, the network device sends N pieces of control information in one scheduling unit, and at this time, the terminal receives N pieces of control information sent by the network device in one scheduling unit.

It should be noted that, the N pieces of control information are used for scheduling or indicating the same physical channel or physical signal, and N is a positive integer greater than or equal to 2.

It should be further noted that the transmission positions of the N control information and/or the indicated parameters may be different; that is, the transmission positions of the N control information may be different, and the parameters indicated by the N control information may be different, thereby enabling the final transmission parameters of the physical channel or physical signal determined based on the transmission positions of the N control information and the indicated parameters to be the same.

It should be noted that the control information may be DCI.

Furthermore, the scheduling unit may be at least one symbol, at least one duration, or at least one slot, wherein the duration comprises at least one consecutive symbol; i.e. a scheduling unit may comprise at least one of one symbol, at least two symbols, one duration (span), at least two durations, one time slot and at least two time slots, without being particularly limited herein.

Step 302: the transmission parameters of the physical channel or physical signal are determined based on the target control information of the N control information.

Specifically, the terminal determines a transmission parameter of the physical channel or the physical signal based on target control information among the N pieces of control information, and the target control information may be at least one of the N pieces of control information.

Further, the terminal may expect the transmission parameters determined according to the transmission position of the target control information and the indicated parameters to be the same. That is, the terminal determines the same transmission parameter according to the transmission position of the at least one control information and the indicated parameter. At this time, the terminal can determine the unique transmission parameter no matter which control information is based on which transmission parameter of the physical channel or the physical signal, so that the terminal can accurately receive the physical channel or the physical signal according to the determined transmission parameter.

Specifically, the transmission parameters determined by the terminal according to the transmission position of the target control information and the indicated parameters are the same, and may be the same according to the transmission position of at least two control information and the indicated parameters; it may be that the terminal expects at least one control information to include the second information field, and the remaining control information except for the at least one control information among the N control information does not include the second information field. The specific limitation is not specifically defined herein.

It should also be noted that the physical channels include at least one of the following: the physical downlink shared channel, the physical uplink shared channel, the physical downlink shared channel using repeated transmission, and the physical uplink shared channel using repeated transmission are not particularly limited herein.

It should also be noted that the physical signal may include an aperiodic channel state information reference signal.

In this way, the terminal in this embodiment receives N pieces of control information for scheduling or indicating the same physical channel or physical signal, and determines the transmission parameters of the physical channel or physical signal based on at least one piece of control information in the N pieces of control information, so that the terminal can determine the unique transmission parameters no matter what control information is based on which control information is used to determine the transmission parameters of the physical channel or physical signal, thereby avoiding the problem that the terminal erroneously determines the position of the physical channel or physical signal when the base station and the terminal determine the transmission parameters of the physical channel or physical signal according to different control information, and further causes failure in transmission of the physical channel or physical signal, and thus enabling the terminal to accurately receive the physical channel or physical signal according to the determined transmission parameters.

Further, in this embodiment, the control information may include a first information field, where the first information field is used to indicate target control information or a reference location to which the terminal refers when determining transmission parameters of the physical channel or the physical signal.

That is, a first information field may be added to the control information, and the target control information or the reference location referred to in determining the transmission parameter of the physical channel or the physical signal may be indicated through the first information field.

Wherein the first information field may contain at least one of the following information:

(1) A format for determining target control information;

(2) Determining the number of steps of the target control information;

(3) For determining the amount of target control information;

(4) A reference position for determining a symbol or slot of a transmission parameter;

(5) A transmission symbol or a transmission slot for determining target control information;

(6) For determining the location of the target control information on the time axis.

In (1), by including a format for determining target control information in the first information field, the terminal is enabled to determine from which control information format to determine transmission parameters of a physical channel or a physical signal.

The format of the target control information may be DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 1_0, DCI format 1_1, DCI format 1_2, or the like, and is not limited thereto.

In (2), the network device may configure the terminal to receive one 2-step control information, in which case the terminal can determine whether to determine transmission parameters of the physical channel or the physical signal according to the first-step or second-step control information by including the number of steps for determining the target control information in the first information field.

In (3), the number of the target control information may be all or part of the control information, and may also be the number of the part of the control information, and by including the number for determining the target control information in the first information field, the terminal is enabled to determine whether to determine the transmission parameters of the physical channel or the physical signal according to the part of the control information or the all of the control information.

In (4), by including a reference position of a symbol or slot for determining the transmission parameter in the first information domain, the terminal is enabled to determine from which symbol or slot the transmission parameter of the physical channel or physical signal is determined.

In (5), by including a transmission symbol or a transmission slot for determining target control information in the first information field, the terminal is enabled to determine a transmission parameter of a physical channel or a physical signal according to which symbol or slot the control information transmitted on is determined.

In (6), by including in the first information field the control information for determining where the target control information is located on the time axis, i.e., the target control information is the first control information, the second control information, or the last control information on the time axis, the terminal is enabled to determine the transmission parameters of the physical channel or the physical signal according to which control information, i.e., what number of transmitted control information, is on the time axis.

Further, in this embodiment, the control information may further include a second information field, where the second information field includes at least one of the following fields:

a time domain resource allocation domain, a frequency domain resource allocation domain, a channel state information request (CSI request) domain, a transmission configuration indication domain, and a redundancy version indication domain.

It should be noted that, the domain included in the second information domain is the same as the domain included in the existing control information, and a detailed description thereof is omitted. In addition, the present embodiment may perform joint coding indication on the target control information through the first information field and the second information field.

Further, in this embodiment, information included in at least one field of N control information is different, where the information field is a first information field or a second information field. In this way, by setting the information contained in at least one of the N pieces of control information to be different, the N pieces of control information can schedule the same transmission parameter. For example, assuming that the value of N is 2, i.e. the terminal receives two control information, and the first control information and the second control information both include a time domain resource allocation domain and a frequency domain resource allocation domain, then the information included in the time domain resource allocation domain in the first control information may be different from the information included in the time domain resource allocation domain in the second control information, and in addition, since the time domain resource positions of the first control information and the second control information are also different, the transmission parameters determined according to the two control information and the different information domains of the two control information are the same. Specifically, taking the transmission positions of PDCCH1 and PDCCH2 in fig. 5 as examples, two control information are respectively transmitted in time slot n and time slot n+1, and the time slot offsets included in the time domain resource allocation domains of the two control information are respectively 2 and 1, the PDSCH can be determined to be transmitted in time slot n+2 according to the transmission position of PDCCH1 and the time slot offset 2, and similarly, the PDSCH can also be determined to be transmitted in time slot n+2 according to the transmission position of PDCCH2 and the time slot offset 1. Similarly, the information contained in the time domain resource allocation domain and the frequency domain resource allocation domain in the first control information may be different from the information contained in the time domain resource allocation domain and the frequency domain resource allocation domain in the second control information.

Further, in the present embodiment, parameters indicated by at least two pieces of control information among the N pieces of control information are different; furthermore, at least one of the indicated parameters is different. This enables the N control information to schedule the same transmission parameters by setting at least one of the parameters indicated by the N control information to be different. For example, assume that the value of N is 2, i.e., the terminal receives two control information, and that 1 parameter among the 3 parameters indicated by the first control information is different from 1 parameter among the 3 parameters indicated by the second control information, e.g., the slot offset parameter is different.

Specifically, when the parameters indicated by at least two pieces of control information in the N pieces of control information are set to be different, each piece of control information may include a transmission parameter related information field, and the parameters indicated by at least one transmission parameter related information field in the at least two pieces of control information are different; or the partial control information in the N pieces of control information comprises a transmission parameter related information field, and the rest control information except the partial control information in the N pieces of control information does not comprise the transmission parameter related information field, and at the moment, the terminal determines the transmission parameter according to the partial control information.

Of course, if the number of the partial control information is at least two, it is also necessary to satisfy that the parameters indicated by at least one transmission parameter related information field are different, so that the terminal can determine the transmission parameters of the unique physical channel or physical signal through the partial control information.

In addition, in this embodiment, a part of the N pieces of control information includes a transmission parameter related information field, and the remaining pieces of control information other than the part of control information in the N pieces of control information do not include the transmission parameter related information field, including at least one combination of the following:

part of the N pieces of control information comprises a transmission configuration indication TCI domain, and the rest of the N pieces of control information except the part of control information does not comprise the TCI domain;

Some of the N control information includes a CSI request field, and the remaining control information of the N control information other than the some control information does not include a CSI request field.

I.e. part of the control information contains a TCI field, and the rest of the control information does not contain a TCI field; it is also possible that part of the control information contains a CSI request field and the rest of the control information does not contain a CSI request field, so as to realize the uniqueness of the final transmission parameter determined by part of the control information.

It should be noted that, at least one of the parameters indicated by the N pieces of control information is different, which may be implemented by using the same or different DCI formats for the N pieces of control information. When at least two control information uses the same DCI format, parameters of an indication of at least one information field of the at least two control information may be different, but the information fields included in the at least two control information and the size of the information fields are the same. When at least two control information uses different DCI formats, not only parameters of an indication of at least one information field of at least two control information may be different, but also at least two control information may contain different information fields, for example, one control information contains a TCI field or a CSI request, and none of the other control information may contain this information field.

Further, specifically, the parameter indicated by the control information may include at least one of the following parameters:

Indication information of the target control information, a start symbol of the scheduled physical channel, a start symbol offset of the scheduled physical channel, a symbol length of the scheduled physical channel, a slot offset of the scheduled physical channel, a trigger state number, a Transmission Configuration Indication (TCI) state of the scheduled or indicated physical channel or physical signal, and a redundancy version of the scheduled physical channel.

Specifically, the indication information of the target control information may be information included in the first information domain, that is, may be at least one of the following information: a format for determining the target control information; a step number for determining the target control information; for determining the amount of the target control information; a reference position for determining a symbol or slot of the transmission parameter; a transmission symbol or a transmission slot for determining the target control information; for determining the location of the target control information on the time axis.

I.e. the network device may add the above parameters to the control information according to the actual requirements for indication of the physical channel or physical signal.

It should be further noted that the N pieces of control information may further include at least one of the following combinations of control information:

At least two control information of the same format; at least two different formats of control information; at least one first format of control information and at least one second format of control information; at least one third format of control information and at least one fourth format of control information; at least two pieces of control information having the same size; at least two control information of different sizes; one of the N pieces of at least two pieces of control information.

Specifically, the control information of the first format may be DCI format 1_1, and the control information of the second format may be DCI format 1_2; the control information of the third format may be DCI format 0_1, and the control information of the fourth format may be DCI format 0_2. Of course, this is not particularly limited here.

In this way, the embodiment receives N pieces of control information for scheduling or indicating the same physical channel or physical signal, so that the terminal can expect that the final transmission parameters of the determined physical channel or physical signal are the same when determining the transmission parameters of the physical channel or physical signal based on at least one piece of control information in the N pieces of control information, so that the terminal can determine the unique transmission parameters no matter which piece of control information is used for determining the transmission parameters of the physical channel or physical signal, thereby avoiding the problem that the terminal erroneously determines the position of the physical channel or physical signal when determining the transmission parameters of the physical channel or physical signal according to different pieces of control information, and further causing the failure of the physical channel or physical signal transmission, and enabling the terminal to accurately receive the physical channel or physical signal according to the determined transmission parameters.

In addition, as shown in fig. 4, a flowchart of steps of a control information transmission method applied to a network device in an embodiment of the present invention is shown, where the method includes the following steps:

step 401: and N pieces of control information are sent to the terminal in one scheduling unit.

Specifically, the N pieces of control information are used for scheduling or indicating the same physical channel or physical signal, so that the terminal determines a transmission parameter of the physical channel or physical signal based on target control information in the N pieces of control information, where the target control information is at least one of the N pieces of control information.

In addition, specifically, the transmission positions and/or indicated parameters of the N control information may be different, so that the transmission parameters of the physical channel or physical signal determined by the terminal based on the transmission position and the indicated parameter of at least one control information of the N control information are the same, thereby ensuring the uniqueness of the determined transmission parameters.

Further, N is a positive integer greater than or equal to 2.

It should also be noted that the network device may be a base station.

In this way, the network device sends N pieces of control information to the terminal in one scheduling unit, and the N pieces of control information are used for scheduling or indicating the same physical channel or physical signal, so that the terminal can determine unique transmission parameters when determining transmission parameters of the physical channel or physical signal based on at least one piece of control information in the N pieces of control information, and the problem that the terminal can accurately receive the physical channel or physical signal according to the determined transmission parameters is solved by the base station and the terminal determining the transmission parameters of the physical channel or physical signal by mistake in determining the positions of the physical channel or physical signal according to different control information, thereby causing failure in transmission of the physical channel or physical signal.

Specifically, the first information field includes at least one of the following information:

(1) A format for determining target control information;

(2) Determining the number of steps of the target control information;

(3) For determining the amount of target control information;

It should be noted that, for the specific description of the above content, reference may be made to the relevant content of the terminal side method embodiment, and no further description is given here.

Further, in this embodiment, the control information may further include a second information field, and the second information field includes at least one of the following fields:

A time domain resource allocation domain, a frequency domain resource allocation domain, a channel state information request CSI request domain, a transmission configuration indication domain, and a redundancy version indication domain.

Further, in this embodiment, information included in at least one field of N control information is different, where the information field is a first information field or a second information field.

Further, in the present embodiment, at least two of the N pieces of control information are different in the parameter indicated by the control information.

Specifically, when the parameters indicated by at least two pieces of control information in the N pieces of control information are different, each piece of control information may include a transmission parameter related information field, and the parameters indicated by at least one transmission parameter related information field in the at least two pieces of control information are different; or part of the N pieces of control information comprises a transmission parameter related information field, and the rest of the N pieces of control information except the part of control information does not comprise the transmission parameter related information field, wherein the terminal determines the transmission parameter according to the part of control information.

In addition, specifically, a part of control information in the N pieces of control information includes a transmission parameter related information field, and the rest of control information in the N pieces of control information except for the part of control information does not include the transmission parameter related information field, including at least one combination of the following:

In addition, specifically, the parameter indicated by the control information includes at least one of the following parameters:

Indication information of target control information, a start symbol of a scheduled physical channel, a start symbol offset of the scheduled physical channel, a symbol length of the scheduled physical channel, a slot offset of the scheduled physical channel, a trigger state number, a transmission configuration of the scheduled or indicated physical channel or physical signal indicates a TCI state and a redundancy version of the scheduled physical channel.

It should be further noted that the N pieces of control information include at least one of the following combinations of control information: at least two control information of the same format; at least two different formats of control information; at least one first format of control information and at least one second format of control information; at least one third format of control information and at least one fourth format of control information; at least two pieces of control information having the same size; at least two control information of different sizes; and one of the at least two steps of control information.

In this way, in this embodiment, N pieces of control information are sent to the terminal in one scheduling unit, where the N pieces of control information are used to schedule the same physical channel or physical signal, so that when the terminal determines the transmission parameters of the physical channel or physical signal based on any one of the N pieces of control information, the terminal can determine the unique transmission parameters, and the problem that the terminal erroneously determines the position of the physical channel or physical signal when the base station and the terminal determine the transmission parameters of the physical channel or physical signal according to different control information, thereby causing failure in transmission of the physical channel or physical signal, is avoided, and accurate reception of the physical channel or physical signal can be achieved by the terminal according to the determined transmission parameters.

The above embodiments are specifically described below by way of specific examples:

Specifically, the network device configures the terminal to receive repeated transmission of a Physical Downlink Control Channel (PDCCH), that is, detect 2 or more control information in one scheduling unit (one slot, multiple slots, or several symbols, etc.), where the 2 or more control information is used to schedule or indicate transmission of the same physical channel or physical signal. The network device uses one information field in the control information to instruct the terminal device to determine the transmission position (resource or parameter) of PDSCH/PUSCH/aperiodic CSI-RS according to which control information the reception position or which symbol.

For example, the network device may configure 2 or more control information as different DCI formats (formats), e.g., 2 or more of DCI formats 0_0, 0_1 and 0_2, or 2 or more of DCI formats 1_0, 1_1 and 1_2, respectively, and further instruct the terminal device through an information field, which DCI format's reception location and content are used to determine the transmission location (resource) of PDSCH/PUSCH/aperiodic CSI-RS. For example, '0' represents DCI format 0_1 or 1_1, and '1' represents DCI format 0_2 or 1_2; for another example, '00' represents DCI format 0_0 or 1_0, '01' represents DCI format 0_1 or 1_1, and '10' represents DCI format 0_2 or 1_2. The above is only illustrative, and other combinations of code point (code point) and DCI format are also possible.

For another example, the network device may configure the terminal device to receive one 2-step control information, and then instruct the terminal device through an information field, and determine a transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to the reception position and content of which step control information. For example, '0' represents first step control information, and '1' represents second step control information.

For another example, the network device instructs the terminal device through the first information field, and determines the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS through the reception position and content of part or all of the control information. For example, '0' represents all control information, '1' represents part of control information; for another example, '00' represents all control information, '01' represents partial information 1, '10' represents partial control information 2, '11' is reservation or partial control information 3, etc. When the network device side instructs the terminal device to determine the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to all the control information, the network device may cause different control information to indicate different transmission parameters, so that the terminal device determines that the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS is the same according to the reception position of each control information and the indicated parameters (for a specific procedure, refer to embodiment two). In this way, the terminal device can correctly determine the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to the detected control information even if it cannot detect all the control information. The partial information 1, the partial information 2, and the partial information 3 may be preconfigured by the network device, and may be in the form of a search space, a set of control resources (CORESET), a set of symbols or time slots, or the like.

For another example, the network device instructs the terminal device through the first information field, determines the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS through which symbol or slot, or determines the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS through which symbol or slot the control information is transmitted. For example, '00' represents a symbol 1, '01' represents a symbol 2, '10' represents a symbol 3, etc.; for another example, '00' represents a1 st symbol of a search space with which high layer signaling is coordinated, '01' represents a2 nd symbol of a search space with which high layer signaling is coordinated, '10' represents a 3 rd symbol of a search space with which high layer signaling is coordinated, and so on; for another example, the symbol or slot (e.g., 1,2,3, etc.) indicated by the information field is a resource used for one of the control information transmissions, and the terminal device uses the control information on the indicated symbol or slot as target control information, and determines the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to the target control information. For another example, the symbol or slot indicated by the information field (e.g., 1,2,3, etc.) is the kth (k=1, 2, …, K is the number of steps of the control information) step control information or the resource used for one of the control information transmissions, and the terminal actually detects the kth step control information on the indicated symbol or slot or detects one of the control information, which indicates that the terminal takes the kth step control information or the monitored one of the control information on the indicated symbol or slot as the target control information, and determines the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to the reception position of the target control information and the signaling content of the target control information. If the terminal does not detect the control information of the kth step on the indicated symbol or slot, or does not detect the control information, the terminal defines it as an error condition. In this case, the transmission of the kth control information or the resources used for one of the control information is also indicated, so that the terminal performs secondary acknowledgement on the target control information (the primary acknowledgement is that the first information field in the control information is received, and the secondary acknowledgement is that other control information is transmitted on the symbol or the slot indicated by the first information field) to ensure that the transmission is correct.

For another example, the network device instructs the terminal device via the first information field, which control information detected on the time axis is the target control information. For example, the first control information system, the second control information, or the last control information detected on the time axis. The terminal determines the transmission parameters of the physical channel or the physical signal according to the receiving position of the indicated target control information and the signaling content of the target control information.

For another example, the information field may be an independent information field, which is only used to instruct the terminal device to determine the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to the control information, that is, the first information field; or may be jointly encoded with other information domains, for example, the joint indication (second information domain) may be jointly encoded with the existing time domain resource allocation domain, frequency domain resource allocation domain, CSI request domain, transmission configuration indication domain, redundancy version indication domain, and the like.

Embodiment two:

It is assumed that in this embodiment, the information field is not used to instruct the terminal to determine the time domain transmission resource of the PDSCH according to which control information, but is the same as the conventional information field, and by setting on the network device side, it is ensured that the transmission parameters determined by the terminal device according to the positions of the plurality of control information and the content of the control information are the same, that is, the positions of the control information are different, the content of the control information is also set to be different, but it is ensured that the finally determined transmission resource of the PDSCH is the same).

It is assumed that the network device transmits N pieces of control information within one scheduling unit, the N pieces of control information being used to schedule or indicate the same physical channel or the same physical signal. The content or indicated parameters of one or more information fields in the N control information are not identical.

For example, referring to fig. 5,N =2, k0 in TDRA field of 2 PDCCHs is 2 or 1, respectively, so that transmission slots of PDSCH indicated by 2 PDCCHs are identical, i.e., transmission parameters of PDSCH determined by a terminal device depending on which PDCCH are identical.

Similarly, when 2 PDCCHs are transmitted in one slot, taking fig. 6 as an example, PDCCH1 and PDCCH2 are transmitted in symbol 3 and symbol 4, respectively, S values in control information carried by them may be different, s=3 in TDRA fields in control information in PDCCH1, and s=2 in TDRA fields in control information in PDCCHs 2, so that starting symbols of PDSCH indicated by control information in 2 PDCCHs are symbol 6, and thus transmission parameters of PDSCH determined by the terminal device according to any PDCCH are the same.

Embodiment III:

For aperiodic CSI-RS transmission, a parameter aperiodic trigger offset (aperiodic Triggering Offset) is configured by higher layer signaling, representing an offset between the slot containing the DCI and the aperiodic CSI-RS resource set transmission slot. If two DCIs are transmitted in different time slots and the offset value of the higher layer configuration is fixed, this may result in a case where the aperiodic CSI-RS transmission slots determined according to the two DCIs are not the same.

At this time, the aperiodic CSI-RS transmission may be triggered only by one DCI, in which 2 pieces of control information adopt different DCI formats and 1 piece of control information includes the CSI request field, and the other piece of control information does not include the field. For example, one of the DCI formats of the 2 control information is DCI format 0_1, one is DCI format0_2, one of the reporting trigger sizes (reportTriggerSize) and reportTriggerSize-ForDCIFormat0_2 of the higher-layer parameters is 0, and one is not 0, for example reportTriggerSize-ForDCIFormat0_2 is 0, that is, the terminal determines the triggering condition of the aperiodic CSI-RS according to the DCI signaling including the CSI request field or the DCI signaling with the reporting trigger size not being 0, so that the situation that the transmission parameters of the aperiodic CSI-RS determined by the terminal according to the 2 control information are inconsistent does not occur.

Embodiment four:

For PDSCH, when the scheduling offset (offset between control information and PDSCH transmission resources) is greater than a predefined threshold, if the DCI does not contain a TCI field, the terminal determines the TCI state of PDSCH according to the TCI state of the control resource set (CORESET) where the PDCCH scheduling PDSCH is located. If none of the N control information includes a TCI field and the terminal has multiple scheduling PDCCHs (N), the terminal cannot determine the TCI state of the PDSCH, which results in transmission failure. Therefore, a part of control information (e.g., at least one control information) among the N control information may include the TCI state, the other control information does not include the TCI state, and the terminal determines the TCI state of the PDSCH according to the control information including the TCI state. That is, the terminal does not expect that all control information does not contain a TCI field.

Fifth embodiment:

When PDSCH or PUSCH is repeatedly transmitted, redundancy versions of each transmission opportunity (TO, transmission occasion) are indicated in DCI, for example, PDSCH is repeatedly transmitted between slots, each slot has a TO of PDSCH, each TO uses a redundancy version, and when there are K TO, for example, k=4, the redundancy information indicated in DCI includes redundancy versions of 4 TO. If multiple DCIs are transmitted in different time slots, the determined TO according TO the positions of the DCIs are different, and the redundancy versions of the same TO indication of different DCIs are different. In this case, it is necessary TO determine one target control information (DCI) for the terminal by using the method of the present invention, or the indicated content of the multiple DCIs, so that the redundancy version of the same TO determined by the terminal according TO the positions of the multiple DCIs and the indicated content in the DCIs is the same, or only some (e.g. 1) of the multiple DCIs have redundancy version information fields, and the other DCIs do not include the information fields.
