[0043] Signal transmission process in a wireless communication system

[0044] FIG. 2 is a flowchart of signal transmission in a wireless communication system to which the embodiments of the present application are applicable. As shown in FIG. 2, the signal transmission process in the wireless communication system can be roughly divided into various channel coding processes S211 to S218 shown in FIG. 2.

[0045] The transmitter performs channel coding on the information to be transmitted (for example, a bit stream of a signal source) in the channel coding process S211, to obtain a coded stream. The information to be transmitted can be in the form of a bit stream.

[0046] The coded stream is modulated into modulation symbols in the modulation process S212.

[0047] In the pilot insertion process S213, a pilot symbol is inserted into the modulation symbols described above to form a signal to be transmitted, wherein the pilot symbol can be used for channel estimation and symbol detection by the receiver.

[0048] In the transmission signal S214, the signal is transmitted to the receiver on a channel. During the transmission of the signal on the channel, noise is usually superimposed on the signal.

[0049] In the channel estimation process S215, the receiver can perform channel estimation based on the pilot signal to obtain channel state information (channel state information-reference signal, CSI), and feed back the CSI to the transmitter through a feedback link, for the transmitter to adjust the channel coding, modulation, precoding and the like.

[0050] In the symbol detection process S216, the received modulation symbols are subjected to symbol detection to obtain a detection result.

[0051] In the demodulation process S217, the received modulation symbols are demodulated based on the detection result to obtain a coded stream.

[0052] In the channel decoding process S218, the code stream is decoded to obtain the recovered information (for example, a recovered bit stream), where the recovered information can be in the form of a bit stream.

[0053] It should be understood that the channel encoding processes S211 to S218 shown in FIG. 2 are only exemplarily listed common signal processing processes in a wireless communication system, and the wireless communication system can further include resource mapping, precoding, interference cancellation, CSI measurement, and other signal processing processes. For brevity, the present application will not be described again.

[0054] Transmission mode of reference signal in PDCCH

[0055] In some communication systems (for example, 5G NR), a resource element group (REG) is introduced as a resource unit of PDCCH. FIG. 3 is a schematic diagram of an REG carrying PDCCH. Referring to FIG. 3, one REG occupies one time domain symbol (for example, an orthogonal frequency division multiplexing (OFDM) symbol) in the time domain and 12 subcarriers in the frequency domain, that is, one REG can include 12 resource elements (REs).

[0056] Continuing to refer to FIG. 3, the reference signal and the control information signal are transmitted in an orthogonal manner in the 12 REs, where the REs used to transmit the reference signal can include 3 REs, and the REs used to transmit the control information can include the other REs in the 12 REs except for the REs used to transmit the reference signal, that is, the REs used to transmit the control information can include the remaining 9 REs in the 12 REs, or in other words, the reference signal and the control information are transmitted in an orthogonal transmission manner in the 12 REs, and therefore, the 12 REs can be referred to as “orthogonal RS REs”.

[0057] In some communication systems (for example, 5G NR), a CCE is introduced as another resource unit of PDCCH. Generally, one CCE can include 6 REGs. FIG. 4(a) to FIG. 4(c) show three kinds of CCEs for carrying PDCCH.

[0058] Referring to FIG. 4(a), one CCE can include 6 REGs, the 6 REGs occupy 3 time domain symbols in the time domain, and each of the 6 REGs occupies 12 subcarriers in the frequency domain, accordingly, the 6 REGs appear as 3 rows in the time domain and 2 columns in the frequency domain.

[0059] Referring to FIG. 4(b), one CCE can include 6 REGs, 6 REGs occupy 2 time domain symbols in time domain, each of 6 REGs occupies 12 subcarriers in frequency domain, and correspondingly, 6 REGs present as 2 rows in time domain and 3 columns in frequency domain.

[0060] Referring to FIG. 4(c), one CCE can include 6 REGs, 6 REGs occupy 1 time domain symbol in time domain, each of 6 REGs occupies 12 subcarriers in frequency domain, and correspondingly, 6 REGs present as 1 row in time domain and 6 columns in frequency domain.

[0061] In some communication systems (for example, 5G NR), CORESET is introduced as another resource unit of PDCCH. Generally, one NR PDCCH includes N (for example, N = 1, 2, 4, 8 or 16) same CCEs, where N is referred to as aggregation level. Generally speaking, the larger N is, the more CCEs are repeated, and the better the PDCCH transmission performance is, but the more transmission resources are occupied for transmitting PDCCH.

[0062] FIG. 5 shows a schematic diagram of CORESET carrying PDCCH. Referring to FIG. 5, one PDCCH can include 6 REGs, 6 REGs occupy 1 time domain symbol in time domain, each of 6 REGs occupies 12 subcarriers in frequency domain, and correspondingly, 6 REGs present as 1 row in time domain and 6 columns in frequency domain.

[0063] Resource allocation of PUCCH

[0064] In some communication systems (for example, 5G system), physical uplink control channel (PUCCH) resource can be indicated by 3 bits in DCI. In addition, a maximum of 32 PUCCH resources can be configured by high layer signaling. When the number of PUCCH resources is not greater than 8, the PUCCH resource can be directly determined according to the indication in DCI. When the number of PUCCH resources is greater than 8, a PUCCH resource can be determined according to CCE index and 3-bit indication information in downlink control information (DCI), and the specific method is described as follows:

[0065] Wherein, r PUCCH represents PUCCH resource index number, N CCE,p represents the number of CCEs in COREST, n CCE,pa first CCE index number occupied by the DCI, Δ PRI a value indicated by the 3-bit indication information in the DCI.

[0066] In a conventional communication system, the PDCCH channel is only used to transmit the DCI, and the downlink data is transmitted through the PDSCH channel, and the time-frequency resources used by the PDSCH are scheduled by the DCI. This scheduling method can multiplex the scheduling information of a large number of terminal devices in one PDCCH for transmission, and the scheduling efficiency of the system is very high. However, as a cost, this scheduling method relies on the blind detection of the terminal device on the PDCCH, that is, even if the network device does not send the DCI of a certain terminal device, the terminal device still needs to periodically search for the DCI in the PDCCH, thereby consuming a large amount of power of the terminal device.

[0067] In some schemes, it is proposed to use a scheduling method based on sequence detection, in which scheme, the terminal device can first detect a sequence indication information, if the sequence indication information is detected to belong to the sequence corresponding to the terminal device, the terminal device can confirm that there is subsequent data to be scheduled to be received, at this time, the terminal device can directly receive the PDSCH located after the sequence indication information. This method can reduce the complexity of PDCCH blind detection, so as to reduce the power consumption of the terminal device in blind detection of the PDCCH. On the other hand, this scheme can efficiently transmit small size data packets (such as carried by the PDCCH) and transmit the DCI for scheduling large size PDSCH data packets. However, in the above scheme, the transmission resources occupied by the PDSCH must be located after the transmission resources of the sequence indication information in the time domain, and the time domain positions of the two are adjacent, otherwise the terminal device cannot confirm the transmission resources occupied by the PDSCH, resulting in that the resource position of the transmission resources occupied by the PDSCH is not flexible enough.

[0068] In addition, the amount of information carried by the sequence indication information is very limited, and the resources of the PDSCH, the PUCCH (such as the resources of the hybrid automatic repeat request (HARQ)-acknowledgment (ACK) channel) cannot be scheduled by the sequence indication information.

[0069] Therefore, in view of the above problems, the embodiments of the present application provide a wireless communication method, in which the position of the first transmission resource can be determined based on a first sequence, wherein the first transmission resource is used to transmit one or more of the following: downlink control information of the first terminal device, uplink control information of the first terminal device, uplink data of the first terminal device, downlink data of the first terminal device, which helps to improve the flexibility of the resource position of the first transmission resource. The wireless communication method of the embodiments of the present application will be described below in combination with FIG. 6. The method shown in FIG. 6 includes step S610.

[0070] In step S610, the first terminal device detects a first sequence, the first sequence being used to determine a resource location of the first transmission resource.

[0071] In some implementations, the first sequence can be a sequence corresponding to the first terminal device, that is, if the first terminal device detects the corresponding first sequence, the first terminal device can determine to send and / or receive information in the first transmission resource, wherein the information can include control information and / or data.

[0072] In some implementations, the first sequence being a sequence corresponding to the first terminal device can be understood as that the first sequence matches (for example, is the same as) a pre-stored sequence of the first terminal device. In the embodiments of the present application, the manner in which the first terminal device obtains the pre-stored sequence is not limited. For example, the pre-stored sequence can be configured for the first terminal device by a network device, or the pre-stored sequence can be configured for the first terminal device in a pre-defined manner.

[0073] In some implementations, the first transmission resource is used to transmit one or more of the following: downlink control information of the first terminal device, uplink control information of the first terminal device, uplink data of the first terminal device, and downlink data of the first terminal device.

[0074] In some implementations, the first transmission resource is used to transmit downlink control information of the first terminal device, which can be understood as that the first transmission resource is used to transmit transmission resources occupied by PDCCH.

[0075] In some implementations, the first transmission resource is used to transmit downlink data of the first terminal device, which can be understood as that the first transmission resource is used to transmit transmission resources occupied by PDSCH. For example, the downlink data can include service data with a small amount of data, or low data rate service data, so that the terminal device can skip receiving the downlink control information and directly receive the downlink data, thereby saving energy consumption.

[0076] In some implementations, the downlink data and / or the downlink control information can be collectively referred to as downlink payload (DL payload).

[0077] In some implementations, the first transmission resource is used to transmit uplink control information of the first terminal device, which can be understood as that the first transmission resource is used to transmit transmission resources occupied by PUCCH.

[0078] In some embodiments, the first transmission resource is used for transmitting uplink data of the first terminal device, which can be understood as that the first transmission resource is used for transmitting a transmission resource occupied by a physical uplink shared channel (PUSCH). For example, the uplink data can include service data with a small data volume, or in other words, low data rate service data. In this way, the terminal device can skip receiving downlink control information and directly transmit uplink data, thereby saving energy consumption.

[0079] In some embodiments, the uplink data and / or the uplink control information can be collectively referred to as uplink payload (UL payload).

[0080] In some embodiments, the uplink payload can include HARQ-ACK, and the HARQ-ACK can be used to indicate whether the first terminal device successfully receives the downlink payload. Of course, in the embodiments of the present application, the uplink payload can also have no relationship with the downlink payload.

[0081] In some embodiments, the first sequence is used to determine the resource location of the first transmission resource, or in other words, the first sequence is used to schedule the first transmission resource.

[0082] In the embodiments of the present application, the first transmission resource is not limited, and in some embodiments, the first transmission resource can include one or more of the following: time domain resource, frequency domain resource, code domain resource.

[0083] In some embodiments, the resource location of the first transmission resource belongs to the first resource set.

[0084] In some embodiments, the first resource set can include one or more transmission resources. In some scenarios, the first resource set can be understood as a first resource area, wherein the first resource area can include one or more transmission resources.

[0085] In some embodiments, the first resource set can include first transmission resources of multiple terminal devices, that is, the sequence-based indicator can be used to determine the transmission resources of the multiple terminal devices, which helps to improve the efficiency of the communication system in indicating the transmission resources of the multiple terminal devices. Of course, in the embodiments of the present application, the first resource set can include first transmission resources of one terminal device, which helps to simplify the complexity of the terminal device in determining the corresponding first transmission resource.

[0086] In some implementations, the first set of resources can include one or more transmission resources for transmitting the same type of information. For example, the one or more resources included in the first set of resources are for downlink transmission. For another example, the one or more resources included in the first set of resources are for uplink transmission. For yet another example, the one or more resources included in the first set of resources are for transmitting downlink control information. For yet another example, the one or more resources included in the first set of resources are for transmitting uplink control information. For yet another example, the one or more resources included in the first set of resources are for transmitting downlink data. For yet another example, the one or more resources included in the first set of resources are for transmitting uplink data. Of course, in embodiments of the application, the first set of resources can include multiple transmission resources for transmitting multiple types of information.

[0087] In some implementations, the multiplexing technique employed by the transmission resources in the first set of resources includes one or more of time division multiplexing (TDM), frequency division multiplexing (FDM), code division multiplexing (CDM), which can help improve the utilization of the transmission resources.

[0088] In some implementations, the multiplexing technique employed by the first set of resources for transmitting different types of information can be the same. For example, the multiplexing technique employed by the first set of resources for transmitting downlink payload can be the same as the multiplexing technique employed by the first set of resources for transmitting uplink payload. Taking PDCSH as the downlink payload and HARQ-ACK as the uplink payload, the multiplexing technique employed by the first set of resources for transmitting PDCSH can be the same as the multiplexing technique employed by the first set of resources for transmitting HARQ-ACK, which is described below in connection with FIG. 10A and FIG. 10B.

[0089] In some other implementations, the multiplexing technique employed by the first set of resources for transmitting different types of information can be different. For example, the multiplexing technique employed by the first set of resources for transmitting downlink payload can be different from the multiplexing technique employed by the first set of resources for transmitting uplink payload. Taking PDCSH as the downlink payload and HARQ-ACK as the uplink payload, the multiplexing technique employed by the first set of resources for transmitting PDCSH can be different from the multiplexing technique employed by the first set of resources for transmitting HARQ-ACK, which is described below in connection with FIG. 10C, FIG. 10D, FIG. 10E, and FIG. 10F.

[0090] In some embodiments, the first resource set includes multiple first transmission resources, which helps to increase the amount of data received or transmitted by the first terminal device on the first transmission resources. Of course, in the embodiments of the present application, the first resource set can include one first transmission resource.

[0091] In some embodiments, the first resource set further includes second transmission resources of the second terminal device, and the number of the second transmission resources is different from the number of the first transmission resources in the first resource set, which helps to improve the flexibility of transmission resource allocation. Of course, in the embodiments of the present application, the number of the second transmission resources is the same as the number of the first transmission resources in the first resource set, which helps to reduce the complexity of determining the transmission resources by each terminal device.

[0092] In some embodiments, the above method further includes: the network device sends first sequence indication information to the first terminal device; and step S610 includes: if the first terminal device detects the first sequence from the first sequence indication information, the first terminal device determines the resource position of the first transmission resource based on the first sequence.

[0093] In some embodiments, the first sequence indication information can include sequences of multiple terminal devices, which helps to schedule the transmission resources of the multiple terminal devices through the first sequence indication information, so as to improve the efficiency of scheduling. Of course, in the embodiments of the present application, the first sequence indication information can include a sequence of one terminal device (i.e. the first terminal device), which helps to simplify the complexity of scheduling the first transmission resource through the first sequence indication information.

[0094] In order to facilitate understanding, the following describes a scheme for determining the resource position of the first transmission resource based on the frequency domain information of the first sequence in the embodiments of the present application in combination with FIG. 7. It is assumed that the resource position of the transmission resource used for transmitting the downlink payload belongs to resource set 1 (as an example of the first resource set), the resource position of the transmission resource used for transmitting the HARQ-ACK belongs to resource set 2 (as an example of the first resource set), the first terminal device is terminal device 1, the first sequence indication information is sequence indication information 1, and the first sequence is sequence 1.

[0095] Referring to FIG. 7, the method shown in FIG. 7 includes steps S710 to S750.

[0096] In step S710, the network device sends the sequence indication information 1 to the terminal device 1.

[0097] In step S720, the terminal device 1 detects whether the preconfigured sequence 1 is included in the sequence indication information 1.

[0098] In some implementations, if the terminal device 1 detects the sequence 1 in the sequence indication information 1, step S740 is performed. Conversely, if the terminal device 1 does not detect the sequence 1 in the sequence indication information 1, step S730 is performed.

[0099] In step S730, the terminal device 1 determines that there is no downlink payload to be received and no HARQ-ACK to be sent, and enters a sleep state to save power consumption.

[0100] In step S740, the terminal device 1 determines the location of the first transmission resource based on the sequence 1, wherein the first transmission resource includes the transmission resource 1 in which the terminal device 1 receives the downlink payload and / or the transmission resource 2 in which the terminal device 1 sends the HARQ-ACK.

[0101] It should be noted that the implementation of determining the transmission location of the first transmission resource based on the sequence can refer to the related description of Embodiment 1 and / or Embodiment 2 below.

[0102] In step S750, the terminal device 1 receives the downlink payload on the transmission resource 1, and / or the terminal device 1 sends the HARQ-ACK to the network device on the transmission resource 2.

[0103] The scheme for determining the first transmission resource in the embodiments of the present application is described below in combination with Embodiment 1 and Embodiment 2.

[0104] Embodiment 1: The resource location of the first transmission resource is determined based on the time domain location corresponding to the first sequence.

[0105] In the embodiments of the present application, the resource location of the first transmission resource is not limited. In some implementations, the resource location of the first transmission resource can include one or more of the following: the time domain location of the first transmission resource and / or the frequency domain location of the first transmission resource.

[0106] In some implementations, the resource location of the first resource set in which the first transmission resource is located is determined based on the time domain location corresponding to the first sequence.

[0107] For example, the resource location of the first resource set used for transmitting the downlink control information and / or the downlink data can be determined based on the time domain location corresponding to the first sequence.

[0108] For another example, the resource location of the first resource set used for transmitting the uplink control information and / or the uplink data can be determined based on the time domain location corresponding to the first sequence.

[0109] In the embodiments of the present application, the time domain position corresponding to the first sequence is not limited. In some implementations, the time domain position corresponding to the first sequence can include the time domain position of the first sequence, that is, the time domain position occupied by the transmission of the first sequence. In other implementations, the time domain position corresponding to the first sequence can include the time domain position of the transmission resource of the first sequence indication information in which the first sequence is located.

[0110] In some implementations, the resource position of the first resource set can be determined based on the time domain position corresponding to the first sequence and the first time domain offset.

[0111] In some implementations, the first time domain offset is used to indicate the time domain offset between the resource position of the first resource set and the time domain position corresponding to the first sequence, or in other words, the first time domain offset is used to indicate the time domain offset of the resource position of the first resource set relative to the time domain position corresponding to the first sequence. Or in other words, the resource position of the first resource set is determined after the first time domain offset from the time domain position corresponding to the first sequence.

[0112] In the embodiments of the present application, the manner of obtaining the first time domain offset is not limited. In some implementations, the first time domain offset can be determined based on one or more of the following manners: predefinition, pre-configuration, configuration of the network device. For example, the network device can configure the first time domain offset through RRC signaling and / or system information.

[0113] In the embodiments of the present application, the unit of the first time domain offset is not limited. In some implementations, the unit of the first time domain offset can include one or more of the following: frame, subframe, slot, symbol, time unit. Of course, in the embodiments of the present application, the unit of the first time domain offset can also be other units introduced in future communication systems.

[0114] For example, assuming that the first resource set is used to transmit downlink control information and / or downlink data, the first time domain offset is S1 symbols, accordingly, the time domain offset between the resource position of the first resource set and the time domain position corresponding to the first sequence is S1 symbols, or in other words, the time domain offset of the resource position of the first resource set relative to the time domain position corresponding to the first sequence is S1 symbols, where S1 is a positive integer greater than or equal to 0.

[0115] For another example, assuming that the first resource set is used to transmit uplink control information and / or uplink data, the first time domain offset is K1 slots, accordingly, the time domain offset between the resource position of the first resource set and the time domain position corresponding to the first sequence is K1 slots, or in other words, the time domain offset of the resource position of the first resource set relative to the time domain position corresponding to the first sequence is K1 slots, where K1 is a positive integer greater than or equal to 0.

[0116] For example, the first resource set is used for transmitting uplink control information and / or uplink data, and the first time domain offset is S2 symbols, and correspondingly, the time domain offset between the resource position of the first resource set and the time domain position corresponding to the first sequence is S2 symbols, or in other words, the time domain offset of the resource position of the first resource set relative to the time domain position corresponding to the first sequence is S2 symbols, where S2 is a positive integer greater than or equal to 0.

[0117] In some implementations, the resource position of the first resource set is later than the time domain position corresponding to the first sequence in the time domain.

[0118] As introduced above, in some scenarios, the first resource set is used for transmitting downlink control information and / or downlink data. Correspondingly, the resource position of the second resource set can be determined based on the resource position of the first resource set and the second time domain offset, that is, the resource position of the second resource set is determined based on the resource position of the first resource set and the second time domain offset.

[0119] In some implementations, the uplink control information and / or uplink data are carried in the second resource set, or in other words, the transmission resource in the second resource set is used for transmitting the uplink control information and / or uplink data.

[0120] In some implementations, the transmission resource of multiple terminal devices can be included in the second resource set, that is, the first sequence indication information can be used to determine the transmission resource of multiple terminal devices, which helps to improve the efficiency of the communication system in indicating the transmission resource of multiple terminal devices. Of course, in the embodiments of the present application, the transmission resource of one terminal device can be included in the second resource set, which helps to simplify the complexity of the terminal device in determining the corresponding transmission resource in the second resource set.

[0121] In the embodiments of the present application, the resource position of the second resource set is not limited. In some implementations, the resource position of the second resource set can be the time domain position of the second resource set. For example, the time domain position of the second resource set can include the starting time domain position and / or the ending time domain position of the second resource set. For example, the time domain position of the second resource set can include the time domain position of the first symbol in the second resource set and / or the position of the last symbol.

[0122] For example, the first resource set is used for carrying downlink data, and correspondingly, the second resource set is used for carrying feedback information (for example, HARQ-ACK) (as an example of uplink control information) for the downlink data.

[0123] In some embodiments, the second time domain offset is used to indicate a time domain offset of the resource position of the second resource set relative to the resource position of the first resource set. That is, the resource position of the second resource set is determined based on the resource position of the first resource set as a starting position and the second time domain offset.

[0124] In the embodiments of the present application, the manner of obtaining the second time domain offset is not limited. In some embodiments, the second time domain offset can be determined based on one or more of the following manners: predefinition, pre-configuration, configuration of the network device. For example, the network device can configure the second time domain offset through RRC signaling and / or system information.

[0125] In the embodiments of the present application, the unit of the second time domain offset is not limited. In some embodiments, the unit of the second time domain offset can include one or more of the following: frame, subframe, slot, symbol, time unit. Of course, in the embodiments of the present application, the unit of the second time domain offset can also be other units introduced in future communication systems.

[0126] For example, the second time domain offset is K2 slots, and correspondingly, the time domain offset between the resource position of the second resource set and the time domain position corresponding to the first sequence is K2 slots, or in other words, the time domain offset of the resource position of the first resource set relative to the time domain position corresponding to the first sequence is K2 slots, where K2 is a positive integer greater than or equal to 0.

[0127] In some embodiments, the resource position of the second resource set is later than the resource position of the first resource set in the time domain. Of course, in the embodiments of the present application, the resource position of the second resource set can be earlier than the resource position of the first resource set in the time domain.

[0128] In some embodiments, the resource position of the first resource set is later than the time domain position corresponding to the first sequence in the time domain, and the resource position of the first resource set is adjacent to the time domain position corresponding to the first sequence, which helps to reduce the time delay of the terminal device in receiving and / or transmitting data at the resource position of the first resource set. Of course, in the embodiments of the present application, the resource position of the first resource set can not be adjacent to the time domain position corresponding to the first sequence.

[0129] It should be noted that for the resource set (also referred to as resource set 2) carrying uplink control information and / or uplink data, two schemes for determining the time domain position are introduced above. That is, based on the time domain position corresponding to the first sequence or based on the resource position of the resource set (as an example of the first resource set, referred to as resource set 1 below) used for transmitting downlink control information and / or downlink data. In the embodiments of the present application, the above two schemes can be used independently or in combination with each other.

[0130] In some implementations, if the above schemes are used in combination, the resource positions of the resource set 2 can be determined based on the time domain positions corresponding to the first sequence and the resource positions of the resource set 1. For example, the time domain offset between the resource positions of the resource set 2 and the resource positions of the resource set 1 is time domain offset 1, and the time domain offset between the resource positions of the resource set 2 and the time domain positions corresponding to the first sequence is time domain offset 2.

[0131] Suppose that the time domain offset 2 is S3 time slots, and the time domain offset 1 is S4 symbols. Accordingly, the resource positions of the resource set 2 are located S3 time slots after the time domain positions corresponding to the first sequence in the time domain, and the resource positions of the resource set 2 are located S4 symbols after the resource positions of the resource set 1 in the time domain, where S3 and S4 are positive integers greater than or equal to 0.

[0132] The above describes the schemes for determining the resource positions of the first resource set and / or the resource positions of the second resource set in the embodiments of the present application. In some scenarios, the first resource set and / or the second resource set can include multiple transmission resources. Therefore, after the resource positions of the first resource set and / or the resource positions of the second resource set are determined, the first terminal device can determine a transmission resource 1 from the first resource set and / or a transmission resource 2 from the second resource set, where the transmission resource 1 is used to transmit downlink data and / or downlink control information to be received by the first terminal device (as an example of the first transmission resource), and the transmission resource 2 is used to transmit uplink data and / or uplink control information to be sent by the first terminal device.

[0133] In the embodiments of the present application, the schemes for determining the transmission resource 1 and / or the transmission resource 2 are not limited. In some implementations, the first terminal device can determine the transmission resource 1 from the first resource set based on a time domain offset 3, and / or determine the transmission resource 2 from the second resource set based on a time domain offset 4.

[0134] For example, the time domain offset 3 is used to indicate the time offset between the transmission resource 1 and the starting time domain position of the first resource set.

[0135] For another example, the time domain offset 4 is used to indicate the time offset between the transmission resource 2 and the starting time domain position of the second resource set.

[0136] In the embodiments of the present application, the manner of obtaining the time domain offset 3 and / or the time domain offset 4 is not limited. In some implementations, the time domain offset 3 and / or the time domain offset 4 can be determined based on one or more of the following manners: predefinition, pre-configuration, and configuration of the network device. For example, the network device can configure the time domain offset 3 and / or the time domain offset 4 through radio resource control (RRC) signaling and / or system information.

[0137] In some other implementations, the resource location of the transmission resource 1 and / or the transmission resource 2 can be directly indicated by the network device. For example, the first resource set is used for transmitting the downlink data, the transmission resource 2 is the transmission resource of the HARQ-ACK, and the network device sends the configuration information 1 to the terminal to indicate the time domain offset K3 and the number S5 of the first symbol of the HARQ-ACK in the time slot for transmitting the HARQ-ACK. Accordingly, the time slot where the HARQ-ACK is located is the K3th time slot after the time slot where the first sequence indication information is located or the time slot where the first resource set is located, and the number of the first symbol of the HARQ-ACK in the time slot is S5, where K3 and S5 are positive integers greater than or equal to 0.

[0138] In some implementations, the time domain length of the first resource set and / or the time domain length of the second resource set can be configured for the first terminal device by the network device through sending the configuration information.

[0139] In some implementations, the time domain length of the first resource set can include the number of time domain resources occupied by the first resource set, where the time domain resource may, for example, be a symbol.

[0140] In some implementations, the time domain length of the second resource set can include the number of time domain resources occupied by the second resource set, where the time domain resource may, for example, be a symbol.

[0141] In some implementations, the time domain length of the transmission resource corresponding to the first terminal device in the first resource set (as an example of the first transmission resource) can be configured for the first terminal device by the network device through sending the configuration information. Of course, in the embodiments of the present application, the time domain length of the transmission resource corresponding to the first terminal device in the first resource set can be determined based on pre-defined information or pre-configured information.

[0142] In some implementations, the length of the transmission resource corresponding to the first terminal device can include the number of time domain resources occupied by the transmission resource corresponding to the first terminal device, where the time domain resource may, for example, be a symbol.

[0143] In some implementations, the time domain length of the transmission resource corresponding to the first terminal device in the second resource set can be configured for the first terminal device by the network device through sending configuration information. Of course, in the embodiments of the present application, the time domain length of the transmission resource corresponding to the first terminal device in the second resource set can be determined based on pre-defined information or pre-configured information.

[0144] In some implementations, the length of the transmission resource corresponding to the first terminal device can include the number of time domain resources occupied by the transmission resource corresponding to the first terminal device, wherein the time domain resource can be, for example, a symbol.

[0145] It should be noted that the configuration information introduced above can be dedicated configuration information for each bandwidth part (bandwidth part, BWP) or carrier, that is, the parameters configured by the above configuration information can be dedicated parameters for each BWP or carrier. Of course, in the embodiments of the present application, the configuration information introduced above can be general configuration information, that is, the parameters configured by the above configuration information can be general parameters for each BWP or carrier.

[0146] In addition, it should be noted that the number of transmission resources in the first resource set and the number of transmission resources in the second resource set are not limited in the embodiments of the present application. In some implementations, the number of transmission resources in the first resource set and the number of transmission resources in the second resource set can be the same to simplify the complexity of the terminal device selecting transmission resources from the two resource sets. In some other implementations, the number of transmission resources in the first resource set and the number of transmission resources in the second resource set can be different to improve the flexibility of the terminal device selecting transmission resources from the two resource sets.

[0147] Embodiment 2: The resource position of the first transmission resource is determined based on the frequency domain information of the first sequence and / or the sequence information of the first sequence.

[0148] In some implementations, the frequency domain information of the first sequence is used to indicate the frequency domain position of the first sequence in the frequency domain resource occupied by the first sequence indication information, wherein the introduction of the first sequence indication information can be referred to the above. Of course, in the embodiments of the present application, the frequency domain information of the first sequence can be used to indicate the subcarrier where the first sequence is located or the comb resource where the first sequence is located.

[0149] In some implementations, the first sequence indication information occupies M subcarriers, and the frequency domain information of the first sequence is used to indicate the subcarrier occupied by the first sequence in the M subcarriers, wherein M is a positive integer.

[0150] In some embodiments, the M subcarriers correspond to one or more staggered FDM comb resources, and the frequency domain information of the first sequence is used to indicate comb resources occupied by the first sequence in the one or more comb resources. In the embodiments of the present application, when the first sequence is transmitted through the comb resources, the first sequence can be multiplexed for channel estimation, which helps to improve the utilization of resources compared with channel estimation based on a dedicated sequence.

[0151] In some embodiments, the resource position of the first transmission resource can also be determined based on the number of transmission resources in the first resource set, and / or the resource position of the first transmission resource can also be determined based on the number of transmission resources occupied by the first terminal device in the first resource set.

[0152] In some embodiments, the number of transmission resources in the first resource set can be replaced by the total number of transmission resources included in the first resource set. In some scenarios, the number can be represented by a parameter "N", where N is a positive integer. For example, the value of N can be a power of 2, which helps multiple terminal devices to select the same number of transmission resources based on the value of N when the first sequence indication information schedules multiple terminal devices.

[0153] In some embodiments, the number of transmission resources occupied by the first terminal device in the first resource set can be replaced by the number of transmission resources available to the first terminal device in the first resource set. In some scenarios, the number can be represented by a parameter "P", where P is a positive integer.

[0154] In some embodiments, the first resource set can include transmission resources of multiple terminal devices, where the parameters P corresponding to some or all of the terminal devices in the multiple terminal devices can be different, which helps to improve the flexibility of the terminal devices in determining transmission resources. This will be described below in connection with FIGS. 12A-12F. Of course, in the embodiments of the present application, the parameters P corresponding to the multiple terminal devices can be the same, which simplifies the complexity of the terminal devices in determining transmission resources in the first resource set. This will be described below in connection with FIGS. 10A-10F and 11A-11F.

[0155] In some embodiments, the first resource set can include transmission resources corresponding to multiple terminal devices, in which case the number of transmission resources occupied by the first terminal device in the first resource set can be less than the number of transmission resources in the first resource set, i.e., P < N. Of course, in the embodiments of the present application, the first resource set can only include transmission resources corresponding to the first terminal device, in which case the number of transmission resources occupied by the first terminal device in the first resource set can be equal to the number of transmission resources in the first resource set, i.e., P = N.

[0156] In some embodiments, the resource location of the first transmission resource is determined based on the index of the comb resource occupied by the first sequence and a first parameter, where the first parameter is determined based on a ratio of the number of transmission resources in the first resource set to the number of transmission resources occupied by the first terminal device in the first resource set, i.e., the first parameter can be represented as "N / P".

[0157] In some embodiments, the resource location of the first transmission resource is determined by the index n1 of the first transmission resource, which is determined by the formula n=Mod(n1,N / P), where n1∈{0,1,…,N―1}, n represents the index of the comb resource occupied by the first sequence, P represents the number of transmission resources occupied by the first terminal device in the first resource set, and N represents the number of transmission resources in the first resource set.

[0158] As described above, the resource location of the first transmission resource can be determined based on the frequency domain information of the first sequence, where the frequency domain information of the first sequence may, for example, include the index of the subcarrier occupied by the first sequence. The determination manner of the index of the subcarrier occupied by the first sequence in the embodiments of the present application is introduced below.

[0159] In some embodiments, the index of the subcarrier occupied by the first sequence can be determined based on the index of the comb resource occupied by the first sequence and a first parameter, where the first parameter is introduced above.

[0160] In some embodiments, the index m of the subcarrier occupied by the first sequence is determined by the formula n=Mod(m,N / P), where m∈{0,1,…,M―1}, n represents the index of the comb resource occupied by the first sequence, P represents the number of transmission resources occupied by the first terminal device in the first resource set, N represents the number of transmission resources in the first resource set, and M represents the number of subcarriers occupied by the first sequence indication information.

[0161] It should be noted that, in the embodiments of the present application, embodiment 1 and embodiment 2 can be used independently or in combination. For example, the position of the first resource set and / or the second resource set can be determined based on the scheme of embodiment 1, and subsequently the transmission resource (i.e., the first transmission resource) used by the first terminal device in the first resource set and / or the second resource set is determined based on the scheme of embodiment 2.

[0162] For ease of understanding, the scheme for determining the resource position of the first transmission resource based on the first sequence of frequency domain information in the embodiments of the present application is introduced below in combination with FIGS. 8 to 12F. It is assumed that the resource position of the transmission resource for transmitting the downlink payload belongs to resource set 1 (as an example of the first resource set), the resource position for transmitting the HARQ-ACK belongs to resource set 2 (as an example of the first resource set), the first transmission resource includes the transmission resource 1 for the terminal device 1 to receive the downlink payload and / or the transmission resource 2 for the terminal device 1 to send the HARQ-ACK, the first terminal device is the terminal device 1, the first sequence indication information is the sequence indication information 1, and the first sequence is the sequence 1.

[0163] Referring to FIG. 8, the method shown in FIG. 8 includes steps S810 to S860.

[0164] In step S810, the network device sends the terminal device 1 the sequence indication information 1.

[0165] In step S820, the terminal device 1 detects whether the preconfigured sequence 1 is included in the sequence indication information 1.

[0166] In some implementations, the terminal device 1 detects the sequence 1 on the subcarrier with index m, where the index m is determined by the formula n = Mod(m, N / P), where m ∈ {0, 1, …, M-1}, n represents the index of the comb resource occupied by the sequence 1, P represents the number of transmission resources occupied by the terminal device 1 in the resource set 1, N represents the number of transmission resources in the resource set 1, and M represents the number of subcarriers occupied by the sequence indication information.

[0167] In some implementations, if the terminal device 1 detects the sequence 1 in the sequence indication information 1, step S840 is performed. Conversely, if the terminal device 1 does not detect the sequence 1 in the sequence indication information 1, step S830 is performed.

[0168] In step S830, the terminal device 1 determines that there is no downlink payload to be received and no HARQ-ACK to be sent, and enters a sleep state to save power consumption.

[0169] In step S840, the terminal device 1 determines the transmission resource 1 for the terminal device 1 to receive the downlink payload in the resource set 1 based on the sequence 1.

[0170] In some implementations, the time domain position of the resource set 1 can be determined based on the time domain position corresponding to the sequence 1. For related introduction, please refer to the description in Embodiment 1.

[0171] In some implementations, the resource position of the transmission resource 1 is determined by the index n1 of the transmission resource 1, and the index n1 of the transmission resource 1 is determined by the formula n = Mod(n DL, n DL ∈ {0, 1, …, N1-1}, n denotes the index of the comb resource occupied by sequence 1, P1 denotes the number of transmission resources occupied by terminal device 1 in resource set 1, and N denotes the number of transmission resources in resource set 1.

[0172] In step S850, terminal device 1 determines, based on sequence 1, transmission resource 2 in resource set 2 in which terminal device 1 transmits HARQ-ACK.

[0173] In some implementations, the time domain position of resource set 2 can be determined based on the time domain position corresponding to sequence 1. For related details, refer to the description in Embodiment 1.

[0174] In some implementations, the resource position of transmission resource 2 is determined by the index n1 of transmission resource 2, and the index n1 of transmission resource 1 is determined by the formula n = Mod(n ACK , n ACK ∈ {0, 1, …, N2-1}, n denotes the index of the comb resource occupied by sequence 1, P2 denotes the number of transmission resources occupied by terminal device 1 in resource set 2, and N denotes the number of transmission resources in resource set 2.

[0175] It should be noted that n ACK and n DL are two parameters used in the process of determining transmission resource 1 and transmission resource 2, which can be understood as two examples of the parameter n1 in the above description. In addition, N1 and N2 are two parameters used in the process of determining transmission resource 1 and transmission resource 2, which can be understood as two examples of the parameter N in the above description. In addition, P1 and P2 are two parameters used in the process of determining transmission resource 1 and transmission resource 2, which can be understood as two examples of the parameter P in the above description.

[0176] In step S860, terminal device 1 receives downlink payload on transmission resource 1, and / or terminal device 1 transmits HARQ-ACK to the network device on transmission resource 2.

[0177] It should be noted that the execution order between the above steps is not limited in the embodiments of the present application. In some implementations, step S860 can be executed after step S840 and step S850. In other implementations, the action of receiving downlink payload in step S860 can be executed before step S850. Correspondingly, the action of transmitting HARQ-ACK in step S860 can be executed after step S850.

[0178] Figure 9 shows a scheme of indicating one or more terminal devices' transmission resources by sequence indication information 1 according to an embodiment of the present application. It is assumed that resource set 1 and resource set 2 each include 4 transmission resources (or in other words, resource set 1 and resource set 2 each include 4 parts), and the 4 transmission resources are multiplexed in a TDM manner. Correspondingly, referring to Figure 9, sequence indication information 1 includes 24 subcarriers (i.e. M = 24), and the 24 subcarriers can be divided into N / P comb subcarrier groups which are staggered distributed, where the value of P is 2 K , K e {0, 1, …, log2N}. In other words, when the value of K is 0, 1, 2 respectively and the value of P is 1, 2, 4 respectively, the 24 subcarriers can be divided into 4 comb resources (see (a) in Figure 9), 2 comb resources (see (b) in Figure 9) and 1 comb resource (see (c) in Figure 9). Correspondingly, the 4 comb resources can carry the sequences corresponding to 4 terminal devices (i.e. terminal device 1 ~ terminal device 4), the 2 comb resources can carry the sequences corresponding to 2 terminal devices (i.e. terminal device 1 ~ terminal device 2), and the 1 comb resource can carry the sequence corresponding to 1 terminal device (i.e. terminal device 1).

[0179] Correspondingly, terminal device 1 ~ terminal device 4 can respectively detect sequence indication information 1. If the value of P is 1, terminal device 1 ~ terminal device 4 can respectively detect 4 possible comb resources to confirm whether the corresponding sequence can be detected. If the value of P is 2, terminal device 1 ~ terminal device 2 can respectively detect 2 possible comb resources to confirm whether the corresponding sequence can be detected. If the value of P is 4, terminal device 1 can detect all subcarriers of sequence indication information 1 to confirm whether the corresponding sequence can be detected. Then, if the corresponding sequence is detected, the value of P and n can be determined according to the comb resource where the detected sequence is located.

[0180] Hereinafter, taking the value of N as 4 as an example, the index n and the number (N / P) of comb resources included in sequence indication information 1 when the value of parameter P is different according to an embodiment of the present application are introduced in combination with Table 1. Referring to Table 1, when the value of P is 1, the number of corresponding comb resources is 4, the index of corresponding comb resources is 0, 1, 2, 3, and the index of corresponding subcarriers can be 0, 1, 2, 3. When the value of P is 2, the number of corresponding comb resources is 2, the index of corresponding comb resources is 0, 1, and the index of corresponding subcarriers can be 0, 1. When the value of P is 4, the number of corresponding comb resources is 1, the index of corresponding comb resources is 0, and the index of corresponding subcarriers can be 0.

[0181] Table 1

[0182] Currently, the PDCCH based on blind detection is one of the main reasons for the power consumption of terminal devices. The terminal device receives the DCI through blind detection of the PDCCH, and then receives the DL load (such as PDSCH) according to the scheduling information in the DCI. Even when the network device does not send the DCI for a certain terminal device, this terminal device must periodically perform blind detection on the PDCCH, resulting in excessive power consumption of the terminal device. In the embodiments of the present application, the scheduling of sequence indication information 1 can reduce the power consumption of the terminal device, because the sequence detection used to receive the sequence indication information 1 is a one-time detection that does not require multiple blind detections, and the sequence detection has much lower power consumption than the DCI decoding based on channel coding (also known as forward error correction coding (FEC)).

[0183] On the other hand, the terminal device can not turn on the demodulator and the FEC decoder when receiving the sequence indication information, in order to save power consumption, and only when the sequence configured for itself (i.e., the corresponding sequence) is detected, the demodulator and the FEC decoder are turned on to receive the DL load or send the UL load, thereby avoiding unnecessary turning on of the demodulator and the FEC decoder to demodulate and / or decode the DL load. In addition, it can avoid premature turning on of the modulator and the FEC encoder to modulate and encode the UL load.

[0184] In another aspect, the DL load in the embodiments of the present application can not only transmit downlink control information, but also transmit small-size downlink data (or low-data-rate downlink data), and the UL load can transmit small-size uplink data (or low-data-rate uplink data) or uplink control information. In this way, for services with small data volume, the terminal device can skip the downlink control information and directly receive the downlink data or send the uplink data, thereby saving a large amount of terminal device power.

[0185] However, when multiple users (or terminal devices) share the transmission resources for transmitting the DL payload and the transmission resources for transmitting the HARQ-ACK, the specific resource scheduling information cannot be carried by only one sequence indication information, that is, the transmission resources of the PDSCH and the corresponding HARQ-ACK cannot be scheduled for each user. Therefore, the embodiment of the present application proposes that the terminal device can determine the position of the DL payload of the terminal device in the DL payload transmission resource area (i.e., resource set 1) and / or the position of the HARQ-ACK of the terminal device in the HARQ-ACK transmission resource area (i.e., resource set 2) according to the frequency domain resource position of the corresponding sequence in the sequence indication information. In this way, the terminal device can be helped to determine the transmission resources of the corresponding DL payload and the transmission resources of the HARQ-ACK without increasing the signaling overhead. The following will be further described with reference to FIGS. 10A to 12F, where M = 24 and N = 4.

[0186] It should be noted that, for the convenience of understanding, the following will be described by taking the resource set 1 as the DL payload transmission resource area and the resource set 2 as the HARQ-ACK transmission resource area. Correspondingly, the transmission resource 1 of the terminal device 1 in the DL payload transmission resource area is referred to as the “transmission resource of the DL payload”, and the transmission resource 2 of the terminal device 1 in the HARQ-ACK transmission resource area is referred to as the “transmission resource of the HARQ-ACK”.
