Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and actions, those skilled in the art can understand that the words such as "first" and "second" do not limit the quantity and execution order.

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "three types" generally indicates that the former and latter associated objects are in an "or" relationship.

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

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 execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

When the control information is repeatedly transmitted in 2 or more than 2 symbols or time slots in a time division multiplexing manner, the terminal may detect the control information or the control channel at 2 or more than 2 monitoring occasions, that is, there are 2 or more than 2 receiving positions of the control information. In this case, if the transmission parameters of the PDSCH, the Physical Uplink Shared Channel (PUSCH), or the non-periodic Channel State Information Reference Signal (CSI-RS) scheduled or indicated by the control Information are determined according to the receiving position of the control Information and the content of the control Information by using the method in the prior art, a case may occur in which the transmission parameters determined according to 2 or more than 2 pieces of control Information are different, and thus the terminal device cannot determine the transmission parameters used by the network device when transmitting the Physical Channel-oriented Signal.

For example, as shown in fig. 1, the terminal device detects PDCCH1 and PDCCH2 in slot n and slot n +1, respectively, and the content of the Downlink Control Information (DCI) carried by 2 PDCCHs is the same, the slot offset K0 in the Time Domain Resource Allocation (TDRA) domain is 1, 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 which PDCCH should be located according to which transmission slot of the PDSCH. If the base station and the terminal determine the PDSCH according to the location of different PDCCHs, for example, the base station determines the transmission slot of the scheduled PDSCH according to the location of PDCCH1 and K0 ═ 1, that is, the PDSCH is transmitted in slot n +1, and the terminal detects the PDSCH according to the location of PDCCH2 and K0 ═ 1, that is, the PDSCH is detected in slot n +2, which may cause the terminal device to determine the location of the PDSCH erroneously, and further cause the PDSCH transmission to fail.

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 the DCI carried by the 2 PDCCHs is the same, the starting symbol S of the PDSCH indicated by the TDRA field is 3, the starting symbol of the PDSCH specified by the location and S of PDCCH1 is symbol 6, and the starting symbol of the PDSCH specified by the location and S of PDCCH2 is symbol 7. Similarly, the terminal cannot determine from which PDCCH the starting symbol of the 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 incorrectly determine the location of the PDSCH, and thus cause the failure of PDSCH transmission.

For another example, for aperiodic CSI-RS transmission, the parameter aperiodtriggering offset is configured by higher layer signaling, indicating the offset between the slot containing DCI and the aperiodic CSI-RS resource set transmission slot. If the two DCI contents are identical and transmitted in different time slots, and the offset value configured by the higher layer is fixed, the aperiodic CSI-RS transmission time slots determined according to the two DCIs may not be 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 incorrectly determine the position of the aperiodic CSI-RS, thereby causing the CSI measurement result to be inaccurate.

In view of the above scenario where the control information is repeatedly transmitted in a time division multiplexing manner, an embodiment of the present invention provides a method for transmitting control information, where a configuration or indication manner at a network device side is used to enable a transmission parameter of a physical channel or a physical signal determined by a terminal device according to one or more pieces of control information to be the same as a transmission parameter used by a base station. That is, the terminal expects that the transmission parameters of the physical channel or the physical signal determined according to two or more pieces of control information sent by the network device side are the same, or the terminal does not expect that the transmission parameters of the physical channel or the physical signal determined according to two or more pieces of control information sent by the network device side are different, or the terminal determines a set of transmission parameters of the physical channel or the physical signal according to two or more pieces of control information sent by the network device side. The determined transmission parameters of the physical channel or physical signal may be transmission parameters (transmission 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 the embodiment of the present invention is shown, where the method includes the following steps:

step 301: and receiving N pieces of control information sent by the network equipment in one scheduling unit.

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

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

Further, the scheduling unit may be at least one symbol, at least one duration, or at least one slot, wherein a duration includes at least one consecutive symbol; that is, one scheduling unit may include at least one of one symbol, at least two symbols, one duration (span), at least two durations, one slot, and at least two slots, which is not particularly limited herein.

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

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

Further, the terminal may expect that the transmission parameters determined according to the transmission position of the target control information and the indicated parameters are the same. That is, the terminal determines the same transmission parameter according to the transmission location 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 determines the 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 terminal expects that the transmission parameters determined according to the transmission position of the target control information and the indicated parameters are the same, and may expect that the transmission parameters determined according to the transmission positions of at least two pieces of control information and the indicated parameters are the same; it may also be that the terminal expects at least one control information to include the second information field, and the remaining control information of the N control information excluding the at least one control information does not include the second information field. And is not particularly limited herein.

It should be further noted that the physical channel includes at least one of the following channels: the physical downlink shared channel, the physical uplink shared channel, the physical downlink shared channel using the repeat transmission, and the physical uplink shared channel using the repeat 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 the N pieces of control information used for scheduling or indicating the same physical channel or physical signal, and determines the transmission parameter 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 parameter no matter which control information the terminal determines the transmission parameter of the physical channel or physical signal, thereby avoiding the problem that the terminal determines the position of the physical channel or physical signal incorrectly when the base station and the terminal determine the transmission parameter of the physical channel or physical signal according to different pieces of control information, and further causing transmission failure of the physical channel or physical signal, and thus enabling the terminal to achieve accurate reception of the physical channel or physical signal according to the determined transmission parameter.

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 that the terminal refers to when determining transmission parameters of a physical channel or a physical signal.

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

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

(1) determining a format of the target control information;

(2) a step number for determining 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 position 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 a transmission parameter of a physical channel or a physical signal is determined.

The format of the target control information may be DCI format0_ 0, DCI format0_ 1, DCI format0_2, DCI format1_0, DCI format1_ 1, or DCI format1_ 2, and the like, which is not limited herein.

In (2), the network device may configure the terminal to receive a 2-step control information, in which case the terminal is enabled to determine whether to determine the transmission parameter 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 a number of part of the control information, and at this time, 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 parameter of the physical channel or the physical signal according to the part of the control information or the whole control information.

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

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 is transmitted.

In (6), by including in the first information field 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 on the time axis, i.e., the control information transmitted the next time.

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.

It should be noted that the fields included in the second information field are the same as the fields included in the existing control information, and are not described herein again. 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, at least one of the information fields in the N pieces of control information includes different information, where the information field is a first information field or a second information field. In this way, by setting that information contained in at least one of the information fields of the N pieces of control information is different, the N pieces of control information can schedule the same transmission parameter. For example, assuming that the value of N is 2, that is, the terminal receives two pieces of control information, and the first control information and the second control information both include a time domain resource allocation field and a frequency domain resource allocation field, information included in the time domain resource allocation field in the first control information may be different from information included in the time domain resource allocation field in the second control information. Specifically, taking the transmission positions of PDCCH1 and PDCCH2 in fig. 5 as an example, two pieces of control information are transmitted in time slot n and time slot n +1, respectively, and the time slot offsets included in the time domain resource allocation fields of the two pieces of control information are 2 and 1, respectively, it is possible to determine that the PDSCH is transmitted in time slot n +2 according to the transmission position of PDCCH1 and time slot offset 2, and similarly, it is also possible to determine that the PDSCH is transmitted in time slot n +2 according to the transmission position of PDCCH2 and 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.

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

Specifically, when 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 parameters indicated by at least one transmission parameter related information field in the at least two pieces of control information are different; or, a part of the N control information includes a transmission parameter related information field, and the remaining control information except the part of the control information in the N control information does not include the transmission parameter related information field, at this time, the terminal determines the transmission parameter according to the part of the control information.

Of course, if the number of the partial control information is at least two, it also needs to be satisfied 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 control information of the N pieces of control information except the part of the control information does not include the transmission parameter related information field, which includes at least one of the following combinations:

part of the N pieces of control information comprises a Transmission Configuration Indication (TCI) field, and the rest of the N pieces of control information except the part of the control information does not comprise the TCI field;

part of the N pieces of control information comprises a CSI request field, and the rest of the N pieces of control information except the part of the control information does not comprise the CSI request field.

That is, part of the control information may include the TCI field, and the rest of the control information does not include the TCI field; and part of the control information can also comprise a CSI request field, and the rest of the control information does not comprise the CSI request field, so that the uniqueness of the final transmission parameters determined by the part of the control information is realized.

It should be further noted that, at least one of the parameters indicated by the N pieces of control information is different, and the at least one of the parameters may be implemented by using the same or different DCI formats for the N pieces of control information. When the at least two pieces of control information use the same DCI format, the indicated parameter of the at least one information field of the at least two pieces of control information may not be the same, but the information fields included in the at least two pieces of control information and the sizes of the information fields are the same. When the at least two pieces of control information use different DCI formats, not only may parameters indicated by at least one information field of the at least two pieces of control information be different, but also the at least two pieces of control information may include different information fields, for example, one piece of control information includes a TCI field or a CSI request, and the other pieces of control information may not include the 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 status number, a Transmission Configuration Indication (TCI) status 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 field, that is, 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 location 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 position of the target control information on a time axis.

That is, the network device may add the above parameters to the control information according to actual requirements to indicate a physical channel or a physical signal.

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

at least two pieces of control information of the same format; at least two different formats of control information; at least one control information in a first format and at least one control information in a second format; at least one control information of a third format and at least one control information of a fourth format; at least two pieces of control information having the same size; at least two pieces of control information different in size; one of the N at least two-step control messages.

Specifically, the control information in the first format may be DCI format1_ 1, and the control information in the second format may be DCI format1_ 2; the control information of the third format may be DCI format0_ 1, and the control information of the fourth format may be DCI format0_ 2. This is, of course, not limited to the above.

Thus, the present embodiment can provide a scheduling scheme for scheduling or indicating a physical channel or physical signal by receiving N control information, so that the terminal can expect the determined final transmission parameters of the physical channel or the physical signal to be the same when determining the transmission parameters of the physical channel or the physical signal based on at least one control information of the N control information, so that the terminal can determine a unique transmission parameter regardless of which control information the terminal determines the transmission parameter of the physical channel or physical signal based on, thereby preventing the terminal from erroneously determining the location of the physical channel or the physical signal when the base station and the terminal determine the transmission parameters of the physical channel or the physical signal according to different control information, and further, the problem of transmission failure of the physical channel or the physical signal is caused, so that the terminal can accurately receive the physical channel or the physical signal according to the determined transmission parameter.

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

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

Specifically, the N pieces of control information are used to schedule or indicate 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 the indicated parameters of the N pieces of control information may be different, so that the transmission parameters of the physical channel or the physical signal determined by the terminal based on the transmission position of at least one piece of control information in the N pieces of control information and the indicated parameters 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 the unique transmission parameter when determining the transmission parameter of the physical channel or physical signal based on at least one piece of control information in the N pieces of control information, thereby avoiding the problem that the terminal determines the position of the physical channel or physical signal incorrectly when determining the transmission parameter of the physical channel or physical signal according to different pieces of control information, and further causing the transmission failure of the physical channel or physical signal, and further enabling the terminal to realize the accurate reception of the physical channel or physical signal according to the determined transmission parameter.

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

(1) determining a format of the target control information;

(2) a step number for determining target control information;

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

It should be noted that, for specific description of the above, reference may be made to the related contents of the terminal side method embodiment, and details are not described herein again.

the channel state information allocation method comprises 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, at least one of the information fields in the N pieces of control information includes different information, where the information field is a first information field or a second information field.

In addition, further, in the present embodiment, at least two control information of the N control information indicate different parameters.

Specifically, when 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 parameters indicated by at least one transmission parameter related information field in the at least two pieces of control information are different; or, a part of the N control information includes a transmission parameter related information field, and the remaining control information of the N control information excluding the part of the control information does not include the transmission parameter related information field, wherein the terminal determines the transmission parameter according to the part of the control information.

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

In addition, specifically, the parameter indicated by the control information includes 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 status number, a transmission configuration of the scheduled or indicated physical channel or physical signal indicates the TCI status 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 control information combinations: at least two pieces of control information of the same format; at least two different formats of control information; at least one control information in a first format and at least one control information in a second format; at least one control information of a third format and at least one control information of a fourth format; at least two pieces of control information having the same size; at least two pieces of control information different in size; 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, and the N pieces of control information are used for scheduling the same physical channel or physical signal, so that the terminal can determine the unique transmission parameter when determining the transmission parameter of the physical channel or physical signal based on any one of the N pieces of control information, thereby avoiding the problem that the terminal determines the position of the physical channel or physical signal incorrectly when determining the transmission parameter of the physical channel or physical signal according to different pieces of control information, and further causing the transmission failure 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 parameter.

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

the first embodiment is as follows:

specifically, the network device configures the terminal to receive the repeated transmission of the Physical Downlink Control Channel (PDCCH), that is, detects 2 or more pieces of control information in one scheduling unit (one slot, multiple slots, or several symbols, etc.), where the 2 or more pieces of control information are used to schedule or indicate the 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 reception position or which symbol.

For example, the network device may configure 2 or more pieces of control information into different DCI formats (formats), for example, 2 or more pieces of DCI formats 0_0, 0_1, and 0_2, or 2 or more pieces of DCI formats 1_0, 1_1, and 1_2, and further instruct the terminal device through the information field to use the receiving position and content of which DCI format to determine the transmission position (resource) of PDSCH/PUSCH/aperiodic CSI-RS. For example, '0' denotes DCI format0_ 1 or 1_1, '1' denotes DCI format0_2 or 1_ 2; for another example, '00' indicates DCI format0_ 0 or 1_0, '01' indicates DCI format0_ 1 or 1_1, '10' indicates DCI format0_2 or 1_2, and the like. The above is only an illustrative example, and other combinations of code points (code points) and DCI formats may be used.

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 the information field to determine the transmission location (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to the received location and content of which step of 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 PDSCH/PUSCH/aperiodic CSI-RS through the reception position and content of part of or all of the control information. For example, '0' represents the entire control information, '1' represents a part of the control information; for another example, '00' indicates the entire control information, '01' indicates the partial information 1, '10' indicates the partial control information 2, '11' is the reserved or partial control information 3, and the like. When the network device side instructs the terminal device to determine the transmission positions (resources) 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 positions (resources) of the PDSCH/PUSCH/aperiodic CSI-RS are all the same according to the receiving position of each control information and the parameters indicated by the same (the specific process may refer to embodiment two). Thus, the terminal device can correctly determine the transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS based on 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 pre-configured by the network device, and may be in the form of a search space, a control resource set (CORESET), a set of symbols or time slots, and 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 control information transmitted on which symbol or slot. For example, '00' means symbol 1, '01' means symbol 2, '10' means symbol 3, etc.; for another example, '00' denotes a 1 st symbol of a search space coordinated by higher layer signaling, '01' denotes a 2 nd symbol of a search space coordinated by higher layer signaling, '10' denotes a 3 rd symbol of a search space coordinated by higher layer signaling, etc.; 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 the target control information, and determines the transmission position (resource) of PDSCH/PUSCH/aperiodic CSI-RS according to the target control information. For another example, a symbol or a slot (e.g., 1,2, 3, etc.) indicated by the information field is kth (K is 1,2, …, K is the number of steps of the control information) step control information or a resource used for transmitting one of the control information, and the terminal actually detects the kth step control information on the indicated symbol or slot, or detects one control information, which means that the terminal uses the kth step control information or the monitored one control information on the indicated symbol or slot as target control information, and determines a transmission position (resource) of the PDSCH/PUSCH/aperiodic CSI-RS according to a reception position of the target control information and a signaling content of the target control information. If the terminal does not detect the control information of the k-th 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 resource used for indicating the transmission of the control information of the kth step or one of the control information is also used for the terminal to perform 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 time slot indicated by the first information field) to ensure that the transmission is correct.

For another example, the network device indicates the terminal device through the first information field, and the detected several control information on the time axis is the target control information. For example, the first control information, the second control information, or the last control information detected on the time axis. And enabling the terminal to determine the transmission parameters of the physical channel or the physical signal according to the indicated receiving position of the target control information and the signaling content of the target control information.

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

Example 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 the terminal device is ensured to determine the same transmission parameter according to the positions of the plurality of control information and the content of the control information through the setting of the network device side, that is, the positions of the control information are different, and the content of the control information is also set to be different, but the finally determined transmission resource of the PDSCH is ensured to be the same).

It is assumed that a network device sends N pieces of control information in one scheduling unit, where the N pieces of control information are 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 of the N control information are not identical.

For example, referring to fig. 5, N is 2, and k0 in the TDRA field in 2 PDCCHs is 2 or 1, respectively, so that the transmission time slots of the PDSCH indicated by the 2 PDCCHs are the same, that is, the transmission parameters of the PDSCH determined by the terminal device are the same regardless of which PDCCH.

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, and the values of S in the control information they carry may be different, where S in the control information in PDCCH1 is 3 in the TDRA domain, and S in the control information in PDCCH2 is 2 in the TDRA domain, so that the starting symbol of PDSCH indicated by the control information in 2 PDCCHs is symbol 6, and therefore the terminal device has the same transmission parameters of PDSCH regardless of which PDCCH is determined.

Example three:

for aperiodic CSI-RS transmission, the parameter aperiodic Triggering Offset (aperiodic Triggering Offset) is configured by higher layer signaling, representing the Offset between the slot containing DCI and the aperiodic CSI-RS resource set transmission slot. If two DCIs are transmitted in different time slots and the offset value configured by a higher layer is fixed, the situation that the aperiodic CSI-RS transmission time slots determined according to the two DCIs are different can be caused.

At this time, aperiodic CSI-RS transmission may be triggered through only one DCI, specifically, 2 pieces of control information adopt different DCI formats, and 1 piece of control information includes a 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 pieces of control information is DCI format0_ 1, and the other is DCI format0_2, and one of a reporting trigger size (reporttrigger size) and a reporttrigger size-format 0_2 of the higher-layer parameters is 0 and the other is not 0, for example, reporttrigger size-format 0_2 is 0, that is, the terminal determines the trigger condition of the aperiodic CSI-RS according to the DCI signaling containing the CSI request field or the DCI signaling with the reporting trigger size not being 0, so that the condition that the aperiodic CSI-RS transmission parameters determined by the terminal according to the 2 pieces of control information are inconsistent does not occur.

Example four:

for the PDSCH, when the scheduling offset (offset between control information and PDSCH transmission resources) is greater than a predefined threshold, if the DCI does not include the TCI field, the terminal determines the TCI state of the PDSCH according to the TCI state of the control resource set (CORESET) in which the PDCCH that schedules the PDSCH is located. If the N pieces of control information do not include the TCI field and the terminal has multiple scheduling PDCCHs (N), the terminal may not determine the TCI state of the PDSCH, and transmission may fail. Therefore, it is possible that some of the N pieces of control information (e.g., at least one piece of control information) contain the TCI status, other pieces of control information do not contain the TCI status, and the terminal determines the TCI status of the PDSCH according to the control information containing the TCI status. That is, the terminal does not expect all control information to contain the TCI field.

Example five:

when the PDSCH or PUSCH is repeatedly transmitted, the DCI may indicate redundancy versions of respective Transmission Occasions (TOs), taking the repeated transmission among PDSCH time slots as an example, each time slot has a TOs of the PDSCH, each TO uses one redundancy version, and when there are K TOs, for example, K is 4, the redundancy information indicated in the DCI includes redundancy versions of 4 TOs in total. If a plurality of DCIs are sent in different time slots, the TO determined according TO the positions of the DCIs is different, and the redundancy versions indicated by different DCIs for the same TO are different. At this time, it is necessary TO use the method of the present invention TO determine a piece of target control information (DCI) for the terminal, or the content indicated by a plurality of DCIs, so that the terminal determines that the redundancy versions of the same TO are the same according TO the positions of the plurality of DCIs and the content indicated in the DCI, or only some of the plurality of DCIs (for example, 1) have a redundancy version information field, and the other DCIs do not include this information field.
