[0058] I. Wireless communication system

[0059] As shown in FIG. 2, in a wireless communication system, the basic workflow can include the following steps. At the transmitting end, the transmitter performs channel coding and modulation on the source bit stream to obtain modulation symbols; pilot symbols are inserted into the modulated symbols for channel estimation and symbol detection at the receiving end; finally, the transmitting signal is formed and transmitted to the receiving end through the channel (noise can be added). At the receiving end, the receiver first performs channel estimation on the received signal using the pilot, and feeds back the channel state information (CSI) to the transmitting end through the feedback link for the transmitter to adjust the channel coding, modulation, precoding, etc.; finally, the receiver obtains the final recovered bit stream through symbol detection, demodulation, and channel decoding, etc.

[0060] The above process is a simple illustration, and there are other modules not listed in the traditional communication system, such as resource mapping, precoding, interference cancellation, CSI measurement, etc. These modules can be designed and implemented independently, and then integrated into a complete wireless communication system.

[0061] II. PDCCH resource configuration of 5G system

[0062] 5G NR PDCCH is transmitted periodically in the time domain, and each PDCCH can contain the downlink control information (DCI) of multiple terminals in the cell. Therefore, the terminal needs to perform blind detection on the PDCCH that may contain DCI related to itself at the time domain position configured by the base station, so as to find the DCI related to itself. Even if the base station does not transmit the DCI related to the terminal in a certain PDCCH, the terminal must perform blind detection on this PDCCH. Although this PDCCH detection method realizes the high multiplexing of the DCI of all terminals in the cell, it causes high power consumption of the terminal due to the need to perform a large number of unnecessary blind detections.

[0063] The basic unit of 5G NR PDCCH is a resource element group (REG), as shown in FIG. 3, which is composed of 1 symbol in the time domain and 12 subcarriers in the frequency domain, and contains 12 REs (resource elements), including 3 reference signal (RS) REs and 9 data REs.

[0064] Six REGs constitute a control channel element (CCE), as shown in FIG. 4. An example of the possible structure of REG is as follows:

[0065] For a control resource set (CORESET) of 3 orthogonal frequency division multiplexing (OFDM) symbol length, 6 REGs include 3 rows in time domain x 2 columns in frequency domain.

[0066] For a CORESET of 2 OFDM symbol length, 6 REGs include 2 rows in time domain x 3 columns in frequency domain.

[0067] For a CORESET of 1 OFDM symbol length, 6 REGs include 1 row in time domain x 6 columns in frequency domain.

[0068] One NR PDCCH is composed of N (N = 1, 2, 4, 8 or 16) same CCEs arranged in frequency domain. Taking a CORESET of 3 symbol length as an example, the structure of the PDCCH is shown in FIG. 5. N is called aggregation level. The larger N is, the more CCEs are repeated, and the better the PDCCH transmission performance is, but the more time-frequency resources are consumed.

[0069] The control channel (such as PDCCH and PUCCH) of the 5G system adopts polar encoding, and the data channel (such as PDSCH and PUSCH) adopts low density parity check (LDPC) encoding.

[0070] III. Example of PUCCH resource allocation of 5G system

[0071] 5G can indicate PUCCH resource through 3 bits in DCI. The high layer signaling can configure up to 32 PUCCH resources. When the number of PUCCH resources is not greater than 8, the PUCCH resource is determined directly according to the indication in DCI. When the number of PUCCH resources is greater than 8, a PUCCH resource is determined according to the CCE index and the 3-bit indication information in DCI. For examples of specific methods, see the following formula:

[0072] Wherein, r PUCCH is the PUCCH resource index number, N CCE，p is the number of CCEs in COREST, n CCE,p is the first CCE index number occupied by DCI, Δ PRI is the value indicated by the 3-bit indication information in DCI.

[0073] In the 5G system, the PDCCH channel is only used to transmit DCI, and the downlink data is transmitted through the PDSCH, and the time-frequency resources used by the PDSCH are scheduled by the DCI. This scheduling method can multiplex a large amount of terminal scheduling information 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 on the PDCCH. Even if the base station does not send the DCI of a certain terminal, the terminal also needs to periodically search for the DCI in the PDCCH, thereby consuming a large amount of terminal power.

[0074] In some examples, a scheduling method based on sequence detection can be used. The terminal first detects a sequence indication information, if the sequence belonging to itself is detected, it is explicitly known that there is scheduled data after the sequence indication information, and the PDSCH located after the sequence indication information can be directly received. This method can avoid the complexity of PDCCH blind detection and waste of terminal power consumption, and can efficiently transmit small size data packets and transmit DCI for scheduling large size PDSCH data packets.

[0075] However, only through one sequence indication information, the resources of PDSCH, PUCCH (such as HARQ-ACK) and other channels cannot be scheduled.

[0076] FIG. 6 is a schematic flowchart of a communication method 600 according to an embodiment of the present application. The method can be optionally applied to the system shown in FIG. 1, but is not limited thereto. The method includes at least part of the following contents.

[0077] S610, the first communication device receives sequence indication information;

[0078] S620, in a case where the first communication device detects an indication sequence corresponding to the first communication device from the sequence indication information, the first communication device determines the resource position of the transmission information in the transmission resource area based on the resource position of the indication sequence in the sequence indication information.

[0079] In the embodiments of the present application, the first communication device can receive the sequence indication information (Sequence-based indicator) sent by the second communication device. In some examples, the first communication device can be a terminal device, and the second communication device can be a network device. If the first communication device detects an indication sequence (i.e. the indication sequence corresponding to the first communication device, which can be referred to as a sequence) belonging to itself from the sequence indication information, the first communication device can first determine the position of the transmission resource area based on the resource position of the sequence indication information. Then, based on the resource position of the indication sequence in the sequence indication information, the resource position of the transmission information in the transmission resource area is determined.

[0080] Since the sequence detection is a one-time detection, multiple blind detections are not required, and the sequence detection is much lower in energy consumption than information decoding based on channel coding. When the terminal detects the sequence configured for itself, the resource position of the transmission information in the transmission resource area is determined, and the transmission resource can be determined without increasing signaling overhead. Therefore, the embodiments of the present application can save the energy consumption of the first communication device and improve the data transmission efficiency.

[0081] FIG. 7 is a schematic flowchart of a communication method 700 according to another embodiment of the present application. The method can include one or more features of the above-described methods. In an implementation, the method further includes: S710, determining, by the first communication device, the position of the downlink payload transmission resource area and / or the position of the HARQ-ACK transmission resource area based on the resource position of the sequence indicator information.

[0082] In an implementation, S610 of the method further includes: S720, determining, by the first communication device, the resource position of the downlink payload in the downlink payload transmission resource area and / or the resource position of the HARQ-ACK in the HARQ-ACK transmission resource area based on the resource position of the indicator sequence in the sequence indicator information.

[0083] In the embodiments of the present application, the communication method can include a sequence-based downlink data scheduling and HARQ-ACK resource determination method. Taking a terminal as the first communication device for example, the terminal first receives sequence indicator information. If the terminal detects an indicator sequence belonging to itself from the sequence indicator information, the terminal can determine the specific resource position of the downlink payload of the terminal and the transmission resource position of the HARQ-ACK of the terminal according to the resource position of the sequence of the terminal in the sequence indicator information.

[0084] For example, the terminal first determines the position of the downlink payload transmission resource area (which can be referred to as the downlink payload area) and / or the position of the HARQ-ACK transmission resource area (which can be referred to as the HARQ-ACK area) according to the resource position of the sequence indicator information. Then, the terminal determines the position of the downlink payload of the terminal in the downlink payload transmission resource area and / or the position of the HARQ-ACK of the terminal in the HARQ-ACK transmission resource area according to the resource position of the indicator sequence of the terminal in the sequence indicator information.

[0085] In an implementation, the number of the resource position of the indicator sequence in the sequence indicator information corresponds to the number of the resource position of the downlink payload in the downlink payload transmission resource area and / or the number of the resource position of the HARQ-ACK in the HARQ-ACK transmission resource area.

[0086] In the embodiments of the present application, the number of the resource position can also be a relative value, an intermediate parameter, a relative position, etc. of the resource position. The mapping relationship between the position of the indication sequence in the transmission region of the sequence indication information and the downlink load in the downlink load transmission region and / or the transmission region of the HARQ-ACK in the HARQ-ACK transmission resource region. In some examples, the mapping relationship can be the same, for example, one or more of the number, the relative value, the intermediate parameter, the relative position, etc. are the same. For example, the number of the resource position of the indication sequence in the sequence indication information is the same as the number of the resource position of the downlink load in the downlink load transmission resource region. For another example, the relative position of the resource position of the indication sequence in the sequence indication information is the same as the relative position of the resource position of the downlink load in the downlink load transmission resource region.

[0087] For example, the number of the resource position of the indication sequence in the sequence indication information can be calculated according to the subcarrier number of the detected indication sequence, for example, the calculation result is n. The number of the resource position of the downlink load in the downlink load transmission resource region can be calculated according to the N downlink load transmission parts divided by the downlink load transmission resource region, for example, the calculation result is n. The number of the resource position of the HARQ-ACK in the HARQ-ACK transmission resource region can be calculated according to the N HARQ-ACK transmission parts divided by the HARQ-ACK transmission resource region, for example, the calculation result is n.

[0088] In an embodiment, the resource in the sequence indication information is a Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM) or Code Division Multiplexing (CDM) resource, the resource of the downlink load in the downlink load transmission resource region is a TDM, FDM or CDM resource, and the resource of the HARQ-ACK in the HARQ-ACK transmission resource region is a TDM, FDM or CDM resource. Wherein, TDM is a time domain division manner, FDM is a frequency domain division manner, and CDM is a code domain division manner.

[0089] For example, in the case that the resource in the sequence indication information is a TDM resource, the sequence indication information includes N indication sequences of TDM. In the case that the resource in the sequence indication information is a FDM resource, the sequence indication information includes N indication sequences of FDM. In the case that the resource in the sequence indication information is a CDM resource, the sequence indication information includes N indication sequences of CDM.

[0090] In an embodiment, the downlink payload transmission resource region comprises N downlink payload transmission parts in TDM or N downlink payload transmission parts in FDM; where N is a positive integer. For example, in the case that the resources of the downlink payload in the downlink payload transmission resource region are resources in TDM, the downlink payload transmission resource region comprises N downlink payload transmission parts in TDM. In the case that the resources of the downlink payload in the downlink payload transmission resource region are resources in FDM, the downlink payload transmission resource region comprises N downlink payload transmission parts in FDM.

[0091] In an embodiment, the HARQ-ACK transmission resource region comprises N HARQ-ACK transmission parts in TDM, N HARQ-ACK transmission parts in FDM or N HARQ-ACK transmission sequences in CDM; where N is a positive integer. For example, in the case that the resources of the HARQ-ACK in the HARQ-ACK transmission resource region are resources in TDM, the HARQ-ACK transmission resource region comprises N HARQ-ACK transmission parts in TDM. In the case that the resources of the HARQ-ACK in the HARQ-ACK transmission resource region are resources in FDM, the HARQ-ACK transmission resource region comprises N HARQ-ACK transmission parts in FDM. In the case that the resources of the HARQ-ACK in the HARQ-ACK transmission resource region are resources in CDM, the HARQ-ACK transmission resource region comprises N HARQ-ACK transmission sequences in CDM.

[0092] In an embodiment, N indication sequences in TDM, FDM or CDM can be multiplexed in the sequence indication information. For example, the sequence indication information is used to transmit N indication sequences in TDM, N indication sequences in FDM or N indication sequences in CDM; where N is a positive integer.

[0093] In an embodiment, the downlink payload corresponding to the i-th indication sequence is located in the i-th downlink payload transmission part in the downlink payload transmission resource region, i∈{0, 1,..., N-1}.

[0094] In an embodiment, the HARQ-ACK corresponding to the i-th indication sequence is located in the i-th HARQ-ACK transmission part in the HARQ-ACK transmission resource region, i∈{0, 1,..., N-1}.

[0095] In an embodiment, the sequence indication information is FDMed. For example, the sequence indication information is used to transmit N indication sequences in FDM, where a frequency domain resource region of the sequence indication information includes M subcarriers, and the M subcarriers in the frequency domain resource region of the sequence indication information are divided into N comb subcarrier groups; where M is a positive integer. If one comb subcarrier group can be used to transmit an indication sequence of one UE, then N comb subcarrier groups can be used to transmit indication sequences of N UEs.

[0096] In an embodiment, the number of the resource position of the indication sequence within the sequence indication information is determined based on the subcarrier number at which the indication sequence is detected, the number of comb subcarrier groups, and the repetition number of the resource position.

[0097] In an embodiment, the number of the resource position of the indication sequence within the sequence indication information includes the number of the comb subcarrier group in which the indication sequence is located, the number of the comb subcarrier group is n, the subcarrier number at which the indication sequence is detected is m, the number of comb subcarrier groups is N, and the repetition number of the resource position is P; where n∈{0, 1,..., N / P-1}, m∈{0, 1,..., M}, and Mod(m, N / P) = n. Where Mod() represents the modulo operation.

[0098] Assuming N = 4 and P = 1, then n∈{0, 1, 2, 3}, where when m = 0, n = 0; when m = 1, n = 1; when m = 2, n = 2; and when m = 3, n = 3. Assuming N = 4 and P = 2, then n∈{0, 1}, where when m = 0, n = 0; when m = 1, n = 1; when m = 2, n = 0; and when m = 3, n = 1.

[0099] In an embodiment, the sequence indication information is used to transmit N indication sequences in TDM, where a time domain resource region of the sequence indication information includes N symbols. In one case, one indication sequence can be transmitted on each symbol. For example, if the time domain resource region of the sequence indication information includes 4 symbols, 1 indication sequence is transmitted on each symbol.

[0100] In an embodiment, one indication sequence in TDM corresponds to one downlink load transmission part of the downlink load transmission resource region division and / or one HARQ-ACK transmission part of the HARQ-ACK transmission resource region division.

[0101] In an embodiment, the sequence indication information is used to transmit N indication sequences in CDM, where a code domain resource region of the sequence indication information includes the N indication sequences in CDM.

[0102] In an embodiment, one indication sequence of the CDM of the sequence indication information corresponds to one downlink payload transmission part of the downlink payload transmission resource region division and / or one HARQ-ACK transmission part of the HARQ-ACK transmission resource region division.

[0103] In an embodiment, the number of the resource position of the downlink payload within the downlink payload transmission resource region is determined based on the number of the downlink payload transmission part of the downlink payload transmission resource region division, the number of the downlink payload transmission parts of the downlink payload transmission resource region division, and the repetition number of the resource position.

[0104] In an embodiment, the number of the resource position of the downlink payload within the downlink payload transmission resource region is n, the number of the downlink payload transmission part of the downlink payload transmission resource region division is n DL , the number of the downlink payload transmission parts of the downlink payload transmission resource region division is N, and the repetition number of the resource position is P; wherein n∈{0, 1,..., N / P-1}, n DL ∈{0, 1,..., N-1}, and Mod(n DL , N / P) = n.

[0105] Supposing N = 4 and P = 1, n∈{0, 1, 2, 3}, n DL ∈{0, 1,..., 3}. Wherein n DL = 0, n = 0; n = 1, n = 1; n DL = 2, n = 2; n DL = 3, n = 3. Supposing N = 4 and P = 2, n∈{0, 1}, n DL ∈{0, 1,..., 3}. Wherein n DL = 0, n = 0; n DL = 1, n = 1; n DL = 2, n = 0; n DL = 3, n = 1.

[0106] In an embodiment, the number of the resource position of the HARQ-ACK within the HARQ-ACK transmission resource region is determined based on the number of the HARQ-ACK transmission part of the HARQ-ACK transmission resource region division, the number of the HARQ-ACK transmission parts of the HARQ-ACK transmission resource region division, and the repetition number of the resource position.

[0107] In an embodiment, the number of the resource position of the HARQ-ACK within the HARQ-ACK transmission resource region is n, the number of the HARQ-ACK transmission part of the HARQ-ACK transmission resource region division is nACK , the number of HARQ-ACK transmission parts of the HARQ-ACK transmission resource region division is N, and the number of repetitions of the resource location is P; wherein n e {0, 1,..., N / P-1}, n ACK e {0, 1,..., N-1}, and Mod(n ACK , N / P) = n.

[0108] Suppose N = 4, P = 1, then n e {0, 1, 2, 3}, n ACK e {0, 1,..., 3}. Wherein n ACK = 0, n = 0; n = 1, n = 1; n ACK = 2, n = 2; n ACK = 3, n = 3. Suppose N = 4, P = 2, then n e {0, 1}, n ACK e {0, 1,..., 3}. Wherein n ACK = 0, n = 0; n ACK = 1, n = 1; n ACK = 2, n = 0; n ACK = 3, n = 1.

[0109] In some examples, the frequency domain resource region of the sequence indication information contains M subcarriers, and the subcarrier number is {0, 1,..., M-1}. The downlink load transmission resource region and / or the HARQ-ACK transmission resource region is divided into N parts (N is a power of 2). If the terminal detects its own indication sequence in the subcarrier number Mod(m, N / P =) n of the sequence indication information (P = 2 K , K e {0, 1,..., log2N}), then the downlink load of this terminal is located in those downlink load transmission parts Mod(n DL , N / P) = n of the downlink load transmission resource region (n DL e {0, 1,..., N-1}); the HARQ-ACK of this terminal is located in those HARQ-ACK transmission parts Mod(n ACK , N / P) = n of the HARQ-ACK transmission resource region (n ACK e {0, 1,..., N-1}).

[0110] In an implementation, the location of the downlink load transmission resource region is determined based on the time domain location of the sequence indication information and a first time domain offset, the first time domain offset including a number of time domain resources offset after the time domain location of the sequence indication information. For example, the terminal determines the location of the downlink load transmission resource region according to the time domain location of the sequence indication information and the first time domain offset. The first time domain offset can be predefined or configured by RRC signaling and / or system information.

[0111] In an embodiment, the starting position of the time domain of the downlink payload transmission resource region is located after the sequence indication information and is connected with the sequence indication information. For example, the sequence indication information is located at the first symbol of a time slot, and the starting position of the time domain of the downlink payload transmission resource region is located at the second symbol of the time slot.

[0112] In an embodiment, the first symbol where the downlink payload is located is the S1th symbol after the symbol where the sequence indication information is located, and the first time domain offset is the S1th symbol after the sequence indication information. For example, the sequence indication information is located at the first symbol of a time slot, and the starting position of the time domain of the downlink payload transmission resource region, i.e., the first symbol where the downlink payload is located, is the S1th symbol after the first symbol of the time slot.

For example, the first communication device can determine the position of the HARQ-ACK transmission resource region according to the time domain position of the sequence indication information and the second time domain offset. The second time domain offset is predefined or configured through RRC signaling and / or system information.

[0115] In an embodiment (Method 1), the time slot where the HARQ-ACK is located is the Kth time slot after the time slot where the sequence indication information and / or the downlink payload is located. For example, the sequence indication information is located at time slot K1, and the first communication device can send the HARQ-ACK at the Kth time slot after the time slot K1. For another example, the downlink payload is located at time slot K2, and the first communication device can send the HARQ-ACK at the Kth time slot after the time slot K2.

[0116] In an embodiment, the method further comprises: the first communication device receiving second configuration information, the second configuration information comprising information of the K and information of a symbol number S2 of a first symbol where the HARQ-ACK is located in a slot where the HARQ-ACK is located. In the embodiment, the first communication device can receive the second configuration information sent by the second communication device. For example, the second configuration information can indicate that the first symbol where the HARQ-ACK is located is a symbol S2 of a Kth slot after a slot K1 where the sequence indication information is located. The first communication device can send the HARQ-ACK at the symbol S2 of the Kth slot after the slot K1.

[0117] In an embodiment (Method 2), the first symbol where the HARQ-ACK is located is an S3th symbol after a symbol where the sequence indication information and / or the downlink payload is located.

[0118] In an embodiment, the first communication device receives third configuration information, the third configuration information comprising information of the S3. In the embodiment, the first communication device can receive the third configuration information sent by the second communication device. For example, the third configuration information can indicate that the first symbol where the HARQ-ACK is located is an S3th symbol after a symbol where the sequence indication information is located. The first communication device can start sending the HARQ-ACK from the S3th symbol after the symbol where the sequence indication information is located. For another example, the third configuration information can indicate that the first symbol where the HARQ-ACK is located is an S3th symbol after a symbol where the downlink payload is located. The first communication device can start sending the HARQ-ACK from the S3th symbol after the symbol where the downlink payload is located.

[0119] In an embodiment, the second configuration information and / or the third configuration information further comprises a time domain resource length of the HARQ-ACK. For example, a number L of symbols contained by the HARQ-ACK.

[0120] In the embodiment, one or more of the first configuration information, the second configuration information, and the third configuration information can be transmitted in a same signaling or in different signaling.

[0121] In the embodiment, one or more of the first configuration information, the second configuration information, and the third configuration information can be transmitted in a same RRC configuration signaling or in different RRC configuration signaling. One or more of the first configuration information, the second configuration information, and the third configuration information can be transmitted in a system signaling or in different systems. For example, the first configuration information is transmitted in a first RRC configuration signaling, and the third configuration information is transmitted in a second RRC configuration signaling.

[0122] In an embodiment, the configuration information is common or dedicated to each bandwidth part (BWP) or cell. In the embodiments of the present application, one or more of the first configuration information, the second configuration information, and the third configuration information can be common or dedicated to each bandwidth part (BWP) or cell. For example, the first configuration information corresponds to BWP1, and the second configuration information corresponds to BWP2. For another example, the first configuration information is common, the second configuration information corresponds to BWP3, and the third configuration information corresponds to cell 1.

[0123] In an embodiment, the method further includes: in a case where the first communication device does not detect the indication sequence corresponding to the first communication device from the sequence indication information, the first communication device does not receive the downlink payload and does not send the HARQ-ACK.

[0124] In the embodiments of the present application, after the first communication device receives the sequence indication information sent by the second communication device, if the first communication device does not detect the indication sequence belonging to itself from the sequence indication information, the first communication device can not receive the downlink payload and can not send the HARQ-ACK. In one case, the first communication device does not detect the indication sequence belonging to itself from the sequence indication information, and then stops receiving information after the sequence indication information. In another case, the first communication device does not detect the indication sequence belonging to itself from the sequence indication information, and then stops decoding or demodulating information received after the sequence indication information. In this way, unnecessary energy consumption of the first communication device can be reduced, and transmission efficiency can be improved.

[0152] In an implementation, the method further includes: in a case where there is no indication sequence corresponding to the first communication device in the sequence indication information, the first communication device does not send downlink payload and does not receive HARQ-ACK.

[0153] The specific examples of the method 800 executed by the second communication device of the embodiment can refer to the relevant descriptions of the second communication device in the methods 600 and 700 described above. For brevity, the details are not described herein again.

[0154] The communication method of the embodiment can include a sequence-based downlink data and HARQ-ACK scheduling method. The downlink payload (DL Payload) can not only transmit downlink control information, but also transmit small-size downlink data. In this way, for services with small data volume, the terminal can skip the downlink control information and directly receive low-data-rate downlink data or send low-data-rate uplink data, thereby saving a large amount of terminal power.

[0155] However, when multiple users share the DL Payload and HARQ-ACK resources, only one sequence indication information cannot carry specific resource scheduling information, and cannot schedule the transmission resources of the PDSCH and the corresponding HARQ-ACK. Especially when one sequence indication information corresponds to multiple terminals, it cannot indicate the specific resource position of a terminal in the PDSCH and the HARQ-ACK of multiple terminals. In the embodiment, the terminal determines the position of the DL Payload of the terminal in the DL Payload transmission resource area and / or the position of the HARQ-ACK of the terminal in the HARQ-ACK transmission resource area according to the frequency domain resource position of the sequence of the terminal in the sequence indication information. Thus, the transmission resources of the DL Payload and the HARQ-ACK can be determined without increasing the signaling overhead, and multiple terminals can be supported to be scheduled in one DL Payload area and to transmit the HARQ-ACK in one HARQ-ACK area.

[0156] Embodiment one: the terminal determines the resource positions of the DL Payload and the HARQ-ACK according to the frequency domain position of the detected sequence.

[0157] In this embodiment, the terminal determines its DL Payload resource location in the DL Payload region and / or its HARQ-ACK resource location in the HARQ-ACK region according to the frequency domain location of the sequence (i.e. the indication sequence) that the terminal detects in the sequence-based indicator information. FIG. 9 is a flow diagram illustrating how the terminal determines the resource location of the DL Payload and the HARQ-ACK according to the frequency domain location of the sequence that the terminal detects. As shown in FIG. 9, the terminal, e.g. a UE, first receives the sequence-based indicator information (Receive the sequence-based indicator), and checks whether a sequence configured to the UE is detected in the sequence-based indicator information (Check if a sequence configured to the UE is detected in the sequence-based indicator). If the terminal does not detect a sequence corresponding to the terminal from the sequence-based indicator information, the terminal neither receives the DL Payload in the specific downlink resource nor transmits the HARQ-ACK in the specific uplink resource (Not receive the DL Payload or transmit HARQ-ACK.), and the terminal can go to sleep (UE goes to sleep.). If the terminal detects a sequence belonging to the terminal from the sequence-based indicator information, the terminal determines the location of the DL Payload of the terminal in the DL Payload transmission resource region and / or the location of the HARQ-ACK of the terminal in the HARQ-ACK transmission resource region according to the frequency domain resource location of the sequence of the terminal in the sequence-based indicator information.

[0158] A specific method example includes: assuming that the sequence-based indicator information contains M subcarriers, the subcarrier number m e {0, 1,..., M-1}. The DL Payload transmission resource region and / or the HARQ-ACK transmission resource region is divided into N parts (N is a power of 2). Meanwhile, the M subcarriers in the sequence-based indicator information can also be divided into N comb groups of staggered FDM, the number of the comb is n (n e {0, 1,..., N / P-1}), P = 2 K , K e {0, 1,..., log2N}) in which the terminal detects a sequence belonging to the terminal (i.e. detects a sequence belonging to the terminal in the comb n), the DL Payload of the terminal is located in the Mod(n DL, N / P) = n (n DL The HARQ-ACK of this UE is in part n ACK , N / P) = n (n ACK The HARQ-ACK of this UE is in part n

[0159] UE detected its sequence in subcarriers m with Mod(m, N / P) = n. UE receives its DL Payload in parts n DL , N / P) = n (n DL UE receives its DL Payload in parts n DL with Mod(n DL , N / P) = n in the DL Payload zone. UE transmits its HARQ-ACK in parts n ACK , N / P) = n (n ACK UE transmits its HARQ-ACK in parts n ACK with Mod(n ACK , N / P) = n in the HARQ-ACK zone.

[0160] As an example shown in Figure 10, DL Payload and HARQ-ACK are divided into 4 parts (N = 4) respectively, multiplexed in DL Payload zone and HARQ-ACK zone in TDM manner, and Sequence-based indicator contains 24 subcarriers (M = 24). Then 24 subcarriers can be divided into N / P comb groups distributed in staggered manner, possible value of P is P = 2 K (K e {0, 1,..., log2N}), i.e. K = 0, 1 or 2, P = 1, 2 or 4, 24 subcarriers can be divided into 4, 2 or 1 comb, which can carry sequence of 4, 2 or 1 UE respectively.

[0161] Figure 10 is an example of subcarrier comb multiplexing of sequence-based indicator. Where N=4. If P=1, the subcarriers of sequence-based indicator (or called subcarriers of frequency domain resource region of sequence-based indicator, subcarriers occupied by sequence-based indicator, etc.) are grouped into 4 staggered comb groups, conveying 4 UEs’ sequences. If P=2, the subcarriers of sequence-based indicator are grouped into 2 staggered comb groups, conveying 2 UEs’ sequences. If P=4, the subcarriers of sequence-based indicator are conveying 1 UE’s sequence.

[0162] The terminal detects the sequence-based indicator. For example, for P=1, it detects the 4 possible combs respectively, to see if it can detect its own sequence; for P=2, it detects the 2 possible combs respectively, to see if it can detect its own sequence; for P=4, it detects all the subcarriers of sequence-based indicator, to see if it can detect its own sequence. Then according to the comb where its own sequence is detected, the values of P and n are determined. As shown in the example of Figure 10, according to the values of n corresponding to different combs as shown in Table 1.

[0163] Table 1: Combs contained in sequence-based indicator under different P values (take N=4 as an example)

[0164] The blind detection based PDCCH is one of the main reasons for the terminal power consumption. The terminal receives DCI (Downlink Control Information) by blind detection of PDCCH, and then receives the downlink data channel (such as PDSCH) according to the scheduling information in the DCI. Even if the base station does not send DCI for a certain terminal, the terminal must periodically perform blind detection on PDCCH, causing high energy consumption on the terminal side. The scheduling of sequence indication information in the embodiment can reduce the energy consumption of the terminal. Sequence detection is a one-time detection that does not require multiple blind detections, and sequence detection is much lower in energy consumption than DCI decoding based on channel coding (FEC). Only when the terminal detects the sequence configured for itself, will the DL Payload be received or the UL Payload be transmitted, thereby avoiding unnecessary opening of the demodulator and FEC decoder, demodulating and decoding the DL Payload, and avoiding premature opening of the modulator and FEC encoder, modulating and encoding the UL Payload.

[0165] The DL Payload in the embodiment can not only transmit downlink control information, but also transmit small size downlink data, and the UL Payload can transmit small size uplink data or uplink control information. In this way, for services with small data volume, the terminal can skip the downlink control information and directly receive low data rate downlink data or transmit low data rate uplink data, thereby saving a large amount of terminal power.

[0166] However, when multiple users share the DL Payload and HARQ-ACK resources, only one sequence indication information cannot carry specific resource scheduling information, and cannot schedule the transmission resources of PDSCH and corresponding HARQ-ACK. Especially when one sequence indication information corresponds to multiple terminals, it cannot indicate the specific resource position of a terminal in the PDSCH and HARQ-ACK of multiple terminals. In the embodiment, the terminal determines the position of the DL Payload of the terminal in the DL Payload transmission resource area and / or the position of the HARQ-ACK in the HARQ-ACK transmission resource area according to the frequency domain resource position of the sequence of the terminal in the sequence indication information. Thus, the transmission resources of the DL Payload and the HARQ-ACK can be determined without increasing the signaling overhead, and multiple terminals can be supported in one DL Payload area to schedule the DL Payload of multiple terminals, and in one HARQ-ACK area to transmit the HARQ-ACK of multiple terminals.

[0167] Embodiment 2: An example of determining the resource location of DL Payload and HARQ-ACK by terminal according to the frequency domain location of detected sequence. In this example, each terminal has the same P, and P = 1.

[0168] First of all, it should be noted that "the terminal determines the location of its DL Payload in the DL Payload transmission resource area according to the comb location of the sequence belonging to itself" and "the terminal determines the location of its HARQ-ACK in the HARQ-ACK transmission resource area according to the comb location of the sequence belonging to itself" can be two independent schemes, and do not require both schemes to be used at the same time, and only one can be used.

[0169] As shown in FIG. 11, the DL Payload of each UE in the DL Payload transmission resource area is TDM multiplexed, and the HARQ-ACK of each UE in the HARQ-ACK transmission resource area is also TDM multiplexed. Each part in the DL Payload transmission resource area is TDM multiplexed (DL Payload zone (Different parts are TDM)), and each part in the HARQ-ACK transmission resource area is also TDM multiplexed (HARQ-ACK zone (Different parts are TDM)). In the example, P = 1, and the subcarriers of the sequence-based indicator contain N / P = 4 combs (i.e., the Comb of the Sequence-based indicator, or the Comb of the frequency domain resource area of the Sequence-based indicator, the Comb occupied by the Sequence-based indicator, etc.), which can carry the sequences of 4 UEs. The terminal determines the Mod(n DL , 4) = n part (n DL ∈{0, 1, 2, 3}) of the HARQ-ACK transmission resource area according to the comb location (the value of n, n∈{0, 1,..., N / P-1} i.e., n∈{0, 1, 2, 3}) of the sequence belonging to itself, and the HARQ-ACK of this terminal is located in the Mod(n ACK , 4) = n part (n ACK ∈{0, 1, 2, 3}) of the HARQ-ACK transmission resource area.

[0170] For example, if the terminal detects its sequence in Comb 0 of the Sequence-based indicator, its DL Payload is transmitted in Part 0 of the DL Payload transmission resource region, and / or its HARQ-ACK is transmitted in Part 0 of the HARQ-ACK transmission resource region. If the terminal detects its sequence in Comb 1 of the Sequence-based indicator, its DL Payload is transmitted in Part 1 of the DL Payload transmission resource region, and / or its HARQ-ACK is transmitted in Part 1 of the HARQ-ACK transmission resource region. If the terminal detects its sequence in Comb 2 of the Sequence-based indicator, its DL Payload is transmitted in Part 2 of the DL Payload transmission resource region, and / or its HARQ-ACK is transmitted in Part 2 of the HARQ-ACK transmission resource region. If the terminal detects its sequence in Comb 3 of the Sequence-based indicator, its DL Payload is transmitted in Part 3 of the DL Payload transmission resource region, and / or its HARQ-ACK is transmitted in Part 3 of the HARQ-ACK transmission resource region.

[0171] Figure 11 is an example of determining resource locations of DL Payload and HARQ-ACK by a terminal according to detected frequency domain locations of sequences. Where TDM multiplexing, N=4, P=1. In sequence indication information, the sequences of 4 UEs are staggered FDM. The sequences for UE 1, 2, 3, 4 are placed on Comb 0, 1, 2, 3 respectively (In Sequence-based indicator, the sequences of 4 UEs are staggered FDM. The sequences for UE 1, 2, 3, 4 are placed on Comb 0, 1, 2, 3 respectively.). Since the subcarriers of UE3's sequence is on the Comb 2, the UE's DL Payload is transmitted in Part 2 of DL Payload zone (Since the subcarriers of UE3's sequence is on the Comb 2, the UE's DL Payload is transmitted in Part 2 of DL Payload zone.). Since the subcarriers of UE3's sequence is on the Comb 2, the UE's HARQ-ACK is transmitted in Part 2 of HARQ-ACK zone (Since the subcarriers of UE3's sequence is on the Comb 2, the UE's HARQ-ACK is transmitted in Part 2 of HARQ-ACK zone.).

[0172] Figure 12: An example of determining resource locations of DL Payload and HARQ-ACK by a terminal according to detected frequency domain locations of sequences. Where FDM multiplexing, N=4, P=1. The example shown in Figure 12 is similar to the example shown in Figure 11, except that the multiplexing manner is FDM multiplexing. That is, each part within DL Payload transmission resource zone is FDM multiplexed (DL Payload zone (Different parts are FDM)), and each part within HARQ-ACK transmission resource zone is also FDM multiplexed (HARQ-ACK zone (Different parts are FDM)).

[0173] It should be noted that FIG. 11 and FIG. 12 are examples in which the DL Payload transmission resource region and the HARQ-ACK transmission resource region adopt the same multiplexing mode. However, the DL Payload transmission resource region and the HARQ-ACK transmission resource region can also adopt different multiplexing modes, such as “the DL Payload transmission resource region adopts the TDM multiplexing mode, and the HARQ-ACK transmission resource region adopts the FDM multiplexing mode”, or “the DL Payload transmission resource region adopts the FDM multiplexing mode, and the HARQ-ACK transmission resource region adopts the TDM multiplexing mode”, which are not limited here. These two cases are shown in FIG. 13 and FIG. 14. FIG. 13 is an example in which the terminal determines the resource positions of the DL Payload and the HARQ-ACK according to the frequency domain position of the detected sequence. In this case, the DL Payload is TDM multiplexing, the HARQ-ACK is FDM multiplexing, N = 4, and P = 1. FIG. 14 is an example in which the terminal determines the resource positions of the DL Payload and the HARQ-ACK according to the frequency domain position of the detected sequence. In this case, the DL Payload is FDM multiplexing, the HARQ-ACK is TDM multiplexing, N = 4, and P = 1.

[0174] Figure 15: An example of determining the resource location of DL Payload and HARQ-ACK by the terminal according to the frequency domain location of the detected sequence. In this example, the DL Payload is FDM multiplexed, the HARQ-ACK is CDM multiplexed, N=4, P=1. The example shown in Figure 15 is similar to the examples shown in Figures 11 to 14, the multiplexing manner of the DL Payload transmission resource zone is TDM multiplexing, but the multiplexing manner of the HARQ-ACK transmission resource zone is CDM multiplexing (i.e. code division multiplexing). That is, each part within the DL Payload transmission resource zone is TDM multiplexed, each sequence (i.e. HARQ-ACK transmission sequence) within the HARQ-ACK transmission resource zone is CDM multiplexed (HARQ-ACK zone (Different sequences are CDM)). For example, if the terminal detects the sequence belonging to it in Comb 0 of the Sequence-based indicator, its HARQ-ACK is transmitted in Sequence 0 of the HARQ-ACK transmission resource zone; if the terminal detects the sequence belonging to it in Comb 1 of the Sequence-based indicator, its HARQ-ACK is transmitted in Sequence 1 of the HARQ-ACK transmission resource zone; if the terminal detects the sequence belonging to it in Comb 2 of the Sequence-based indicator, its HARQ-ACK is transmitted in Sequence 2 of the HARQ-ACK transmission resource zone; if the terminal detects the sequence belonging to it in Comb 3 of the Sequence-based indicator, its HARQ-ACK is transmitted in Sequence 3 of the HARQ-ACK transmission resource zone. As shown in Figure 15, since the subcarriers of UE3's sequence are on Comb 2, the UE3's DL Payload is transmitted in Part 2 of the DL Payload zone (Since the subcarriers of UE3's sequence is on the Comb 2, the UE's DL Payload is transmitted in Part 2 of DL Payload zone.). Since the subcarriers of UE3's sequence are on Comb 2, the UE3's HARQ-ACK is transmitted in Sequence 2 of the HARQ-ACK zone.(Since the subcarriers of UE3′s sequence is on the Comb 2,the UE′s HARQ-ACK is transmitted with Sequence 2 in HARQ-ACK zone.)。

[0175] The network can configure a set of sequences to the terminal in advance, which can be used in the HARQ-ACK transmission resource region. Then the terminal determines which sequence is used to transmit the HARQ-ACK of the terminal in the HARQ-ACK transmission resource region from the set of sequences according to the comb number (i.e. the value of n) of the sequence detected as belonging to the terminal.

[0176] Figure 16 is an example of determining the resource position of the DL Payload and the HARQ-ACK according to the frequency domain position of the detected sequence. In this example, the DL Payload is TDM multiplexed, the HARQ-ACK is CDM multiplexed, N=4, and P=1. The example shown in Figure 16 is similar to the example shown in Figure 15, but the multiplexing manner of the DL Payload transmission resource region is FDM multiplexing, and the multiplexing manner of the HARQ-ACK transmission resource region is CDM multiplexing (i.e. code division multiplexing).

[0177] In this embodiment, the terminal determines the position of the DL Payload of the terminal in the DL Payload transmission resource region and / or the position of the HARQ-ACK of the terminal in the HARQ-ACK transmission resource region according to the frequency domain resource position of the sequence of the terminal in the sequence indication information. Thus, the transmission resource of the DL Payload and the HARQ-ACK can be determined without increasing the signaling overhead, and multiple terminals can be scheduled in one DL Payload region and the HARQ-ACK of multiple terminals can be transmitted in one HARQ-ACK region.

[0178] Embodiment Three: An example of determining the resource position of the DL Payload and the HARQ-ACK according to the frequency domain position of the detected sequence - each terminal has the same P, and P=2.

[0179] Compared with Embodiment Two, the scenario of this embodiment is that the number of terminals that need to be scheduled is less than the number N of parts contained in the DL Payload and the HARQ-ACK.

[0180] In the example of this embodiment, N=4, P=2, there are N / P=2 combs in the Sequence-based indicator, which can carry the sequences of 2 UEs. The terminal determines its Mod(n DL ,2) = n (n DL ∈{0,1,2,3}) according to the comb position (the value of n, n∈{0,1,...,N / P-1}, i.e., n∈{0,1}) of the sequence belonging to itself that it detects, and determines the Mod(n ACK ,2) = n (n ACK ∈{0,1,2,3}) of the HARQ-ACK transmission resource area of this terminal.

[0181] For example, if the terminal detects the sequence belonging to itself in Comb 0 of the Sequence-based indicator, its DL Payload is transmitted in the 0th and 2nd parts of the DL Payload transmission resource area, and / or its HARQ-ACK is transmitted in the 0th and 2nd parts of the HARQ-ACK transmission resource area; if the terminal detects the sequence belonging to itself in Comb 1 of the Sequence-based indicator, its DL Payload is transmitted in the 1st and 3rd parts of the DL Payload transmission resource area, and / or its HARQ-ACK is transmitted in the 1st and 3rd parts of the HARQ-ACK transmission resource area;

[0182] Figure 17 is an example of determining the resource locations of DL Payload and HARQ-ACK by the terminal according to the detected frequency domain locations of the sequences. Specifically, the example shown in Figure 17 is an example of TDM multiplexing, N=4, P=2. In the sequence indication information, the sequences of 2 UEs are staggered FDM. The sequences for UE 1, 2 are placed on the Comb 0, 1 respectively (In Sequence-based indicator, the sequences of 2 UEs are staggered FDM. The sequences for UE 1, 2 are placed on the Comb 0, 1 respectively.). Since the subcarriers of UE1's sequence is on the Comb 0, the UE's DL Payload is transmitted in Part 0 and 2 of DL Payload zone (Since the subcarriers of UE1's sequence is on the Comb 0, the UE's DL Payload is transmitted in Part 0 and 2 of DL Payload zone.). Since the subcarriers of UE1's sequence is on the Comb 0, the UE's HARQ-ACK is transmitted in Part 0 and 2 of HARQ-ACK zone (Since the subcarriers of UE1's sequence is on the Comb 0, the UE's HARQ-ACK is transmitted in Part 0 and 2 of HARQ-ACK zone.).

[0183] Figure 18 is an example of determining the resource locations of DL Payload and HARQ-ACK by the terminal according to the detected frequency domain locations of the sequences. Wherein, N=4, P=2. The example shown in Figure 18 is similar to the example shown in Figure 17, except that the multiplexing mode is FDM multiplexing. That is, each part within the DL Payload transmission resource region is FDM multiplexed, and each part within the HARQ-ACK transmission resource region is also FDM multiplexed.

[0184] Figure 19 is "DL Payload transmission resource region adopts TDM multiplexing mode, HARQ-ACK transmission resource region adopts FDM multiplexing mode". In Figure 19, the DL Payload is TDM multiplexed, the HARQ-ACK is FDM multiplexed, N=4, P=2.

[0185] Figure 20 is a "DL Payload transmission resource region with FDM multiplexing mode, HARQ-ACK transmission resource region with TDM multiplexing mode". In Figure 20, DL Payload is FDM multiplexed, HARQ-ACK is TDM multiplexed, N=4, P=2.

[0186] In Figure 21, the multiplexing mode of the DL Payload transmission resource region is FDM multiplexing, but the multiplexing mode of the HARQ-ACK transmission resource region is CDM multiplexing (i.e. code division multiplexing). In Figure 22, the multiplexing mode of the DL Payload transmission resource region is TDM multiplexing, but the multiplexing mode of the HARQ-ACK transmission resource region is CDM multiplexing. In which, N=4, P=2.

[0187] For example, if the terminal detects its sequence in Comb 0 of Sequence-based indicator, its HARQ-ACK is transmitted with Sequence 0 in HARQ-ACK transmission resource zone; if the terminal detects its sequence in Comb 1 of Sequence-based indicator, its HARQ-ACK is transmitted with Sequence 1 in HARQ-ACK transmission resource zone; if the terminal detects its sequence in Comb 2 of Sequence-based indicator, its HARQ-ACK is transmitted with Sequence 2 in HARQ-ACK transmission resource zone; if the terminal detects its sequence in Comb 3 of Sequence-based indicator, its HARQ-ACK is transmitted with Sequence 3 in HARQ-ACK transmission resource zone. As shown in Figure 15, since the subcarriers of UE1's sequence is on the Comb 0, the UE1's DL Payload is transmitted in Part 0 and Part 2 of DL Payload zone. (Since the subcarriers of UE1's sequence is on the Comb 0, the UE's DL Payload is transmitted in Part 0 and Part 2 of DL Payload zone.) Since the subcarriers of UE1's sequence is on the Comb 0, the UE1's HARQ-ACK is transmitted with Sequence 0 and Sequence 2 in HARQ-ACK zone. (Since the subcarriers of UE3's sequence is on the Comb 2, the UE's HARQ-ACK is transmitted with Sequence 0 and Sequence 2 in HARQ-ACK zone.)

[0188] The network can configure a set of sequences to the terminal in advance, which the terminal can use in the HARQ-ACK transmission resource zone, and then the terminal determines which sequence to use in the HARQ-ACK transmission resource zone according to the comb number (i.e. the value of n) of the sequence it detects.

[0189] When the number of terminals to be scheduled is small, more DL resources can be allocated to the terminal for downlink data transmission, and more UL resources can be allocated to the terminal for HARQ-ACK transmission, so that the link adaptation of the terminal can be realized, a larger amount of data can be transmitted, or the reliability and coverage distance of transmission can be improved.

[0190] Embodiment Four: An example of determining the resource positions of DL Payload and HARQ-ACK by a terminal according to the frequency domain positions of the detected sequences—different P values for different terminals.

[0191] In this embodiment, the terminals to be scheduled can have different P values.

[0192] FIG. 23 is an example of a TDM multiplexing mode. Here, N = 4, P of UE1 = 2, P of UE2 = 1, and P of UE3 = 1. UE1 detects a sequence belonging to it in Comb 0 with P = 2, so the DL Payload of this terminal is located in those parts (n DL ∈ {0, 1, 2, 3}) of the DL Payload transmission resource area with Mod(n DL , 2) = 0, i.e., Part 0 and Part 2 of the DL Payload transmission resource area; the HARQ-ACK of this terminal is located in those parts (n ACK ∈ {0, 1, 2, 3}) of the HARQ-ACK transmission resource area with Mod(n ACK , 2) = 0, i.e., Part 0 and Part 2 of the HARQ-ACK transmission resource area. UE2 detects a sequence belonging to it in Comb 1 with P = 1, so the DL Payload of this terminal is located in those parts (n DL ∈ {0, 1, 2, 3}) of the DL Payload transmission resource area with Mod(n DL , 4) = 1, i.e., Part 1 of the DL Payload transmission resource area; the HARQ-ACK of this terminal is located in those parts (n ACK ∈ {0, 1, 2, 3}) of the HARQ-ACK transmission resource area with Mod(n ACK , 4) = 1, i.e., Part 1 of the HARQ-ACK transmission resource area. UE3 detects a sequence belonging to it in Comb 3 with P = 1, so the DL Payload of this terminal is located in those parts (n DL ∈ {0, 1, 2, 3}) of the DL Payload transmission resource area with Mod(n DLPart 3 of DL Payload transmission resource region; HARQ-ACK of this terminal is located in Part 3 of HARQ-ACK transmission resource region. ACK Part 3 of DL Payload transmission resource region; HARQ-ACK of this terminal is located in Part 3 of HARQ-ACK transmission resource region. ACK Part 3 of DL Payload transmission resource region; HARQ-ACK of this terminal is located in Part 3 of HARQ-ACK transmission resource region.

[0193] In Figure 23, in the sequence indicator information, P of UE1 is 2, the sequence of UE1 is on Comb 0; P of UE2 and UE3 is 1, the sequences of UE 2 and UE 3 are placed on two Comb 1 and Comb 3. (In Sequence-based indicator, the sequences of UE1 is on Comb 0 with P=2. Sequences for UE 2, 3 are placed on two Comb 1, 3 with P=1.) HARQ-ACK of UE1 is transmitted in Part 0 and Part 2 of HARQ-ACK zone. HARQ-ACK of UE2 is transmitted in Part 1 of HARQ-ACK zone. HARQ-ACK of UE3 is transmitted in Part 3 of HARQ-ACK zone.

[0194] The example shown in Figure 24 is similar to the example shown in Figure 23, except that the multiplexing manner is FDM multiplexing. That is, each part in the DL Payload transmission resource region is FDM multiplexed, and the HARQ-ACK of each UE in the HARQ-ACK transmission resource region is also FDM multiplexed (that is, each part corresponding to the Sequence-based indicator is also FDM multiplexed. Wherein, N=4, P of UE1 is 2, P of UE2 is 1, P of UE3 is 1.

[0195] Figure 25 is "DL Payload transmission resource region with TDM multiplexing mode, HARQ-ACK transmission resource region with FDM multiplexing mode". In which, DL Payload is TDM multiplexing, HARQ-ACK is FDM multiplexing, N=4, P=2 for UE1, P=1 for UE2, P=1 for UE3. Figure 26 is "DL Payload transmission resource region with FDM multiplexing mode, HARQ-ACK transmission resource region with TDM multiplexing mode". In which, DL Payload is FDM multiplexing, HARQ-ACK is TDM multiplexing, N=4, P=2 for UE1, P=1 for UE2, P=1 for UE3.

[0196] In Figure 27, the multiplexing mode of DL Payload transmission resource region is FDM multiplexing, but the multiplexing mode of HARQ-ACK transmission resource region is CDM multiplexing (i.e. code division multiplexing). In which, DL Payload is TDM multiplexing, HARQ-ACK is CDM multiplexing, N=4, P=2 for UE1, P=1 for UE2, P=1 for UE3. In Figure 28, the multiplexing mode of DL Payload transmission resource region is TDM multiplexing, but the multiplexing mode of HARQ-ACK transmission resource region is CDM multiplexing. In which, DL Payload is FDM multiplexing, HARQ-ACK is CDM multiplexing, N=4, P=2 for UE1, P=1 for UE2, P=1 for UE3.

[0197] For example, UE1 detects its sequence in Comb 0 with P=2, then its HARQ-ACK is transmitted with Sequence 0 and Sequence 2 in HARQ-ACK zone. UE2 detects its sequence in Comb 1 with P=1, then its HARQ-ACK is transmitted with Sequence 1 in HARQ-ACK zone. UE3 detects its sequence in Comb 3 with P=1, then its HARQ-ACK is transmitted with Sequence 3 in HARQ-ACK zone.

[0198] The terminal can be configured by the network in advance with a set of sequences that the terminal can use in the HARQ-ACK transmission resource region, and then the terminal determines which sequence to use for the transmission of its HARQ-ACK in the HARQ-ACK transmission resource region from the set of sequences according to the comb number (i.e., the value of n) of the sequence detected as belonging to the terminal.

[0199] Compared with Embodiment Two and Embodiment Three, this embodiment can support scheduling different sizes of DL Payload or different HARQ-ACK resources for multiple terminals. For example, a terminal located in the center of the cell can be scheduled with less DL Payload or HARQ-ACK resources, and a terminal located at the edge of the cell can be scheduled with less DL Payload or HARQ-ACK resources, so as to realize link adaptation of different terminals, and realize higher spectral efficiency while ensuring the reliability and coverage distance of transmission.

[0200] Embodiment Five: An example of determining the resource position of DL Payload and HARQ-ACK according to the number of detected sequences by the terminal

[0201] In this embodiment, in the sequence-based indicator, the sequences of different terminals are multiplexed in a CDM manner, i.e., share the same time-frequency resources.

[0202] FIGS. 29 and 30 are examples of TDM and FDM of DL Payload and HARQ-ACK, respectively. If the terminal detects a sequence (Sequence n) belonging to itself in the sequence-based indicator, it receives its own DL Payload in the nth part of the DL Payload transmission resource region, and / or sends its own HARQ-ACK in the nth part of the HARQ-ACK transmission resource region.

[0203] In FIG. 29, DL Payload and HARQ-ACK are TDM multiplexed. In the sequence indication information, the sequences of 4 UEs are CDM. The sequences for UE 1, 2, 3, 4 are Sequence 0, 1, 2, 3 respectively (In Sequence-based indicator, the sequences of 4 UEs are CDM. The sequences for UE 1, 2, 3, 4 are Sequence 0, 1, 2, 3 respectively.). Since UE3's sequence is Sequence 2, the UE's DL Payload is transmitted in Part 2 of DL Payload zone (Since UE3's sequence is Sequence 2, the UE's DL Payload is transmitted in Part 2 of DL Payload zone.). Since UE3's sequence is Sequence 2, the UE's HARQ-ACK is transmitted in Part 2 of HARQ-ACK zone (Since UE3's sequence is Sequence 2, the UE's HARQ-ACK is transmitted in Part 2 of HARQ-ACK zone.).

[0204] In FIG. 30, DL Payload and HARQ-ACK are FDM multiplexed. In FIG. 31, the multiplexing manner of HARQ-ACK is CDM. In the sequence indication information, the sequences of 4 UEs are CDM. The sequences for UE 1, 2, 3, 4 are Sequence 0, 1, 2, 3 respectively (In Sequence-based indicator, the sequences of 4 UEs are CDM. The sequences for UE 1, 2, 3, 4 are Sequence 0, 1, 2, 3 respectively.). If the terminal detects the sequence (Sequence n) belonging to itself in the sequence-based indicator, it sends its HARQ-ACK in the HARQ-ACK transmission resource area by using sequence n.

[0205] It should be noted that in the embodiment, DL Payload and HARQ-ACK can respectively select various multiplexing manners such as FDM, TDM, CDM, and various multiplexing manner combinations are not enumerated one by one, but are not limited.

[0206] The embodiment of the present application provides a sequence-based downlink data and HARQ-ACK scheduling method. The DL Payload can not only transmit downlink control information, but also transmit small-size downlink data. In this way, for a service with small data volume, a terminal can skip the downlink control information and directly receive low-data-rate downlink data or transmit low-data-rate uplink data, thereby saving a large amount of terminal power.

[0207] However, when multiple users share the DL Payload and the HARQ-ACK resource, the specific resource scheduling information cannot be carried by only one sequence indication information, the transmission resource of the PDSCH and the corresponding HARQ-ACK cannot be scheduled, especially when one sequence indication information corresponds to multiple terminals, the specific resource position of a terminal in the PDSCH and the HARQ-ACK of multiple terminals cannot be indicated. In the embodiment, the terminal determines the position of the DL Payload of the terminal in the DL Payload transmission resource area and / or the position of the HARQ-ACK in the HARQ-ACK transmission resource area according to the frequency domain resource position of the sequence of the terminal in the sequence indication information. Therefore, the transmission resource of the DL Payload and the HARQ-ACK can be determined without increasing the signaling overhead, and the DL Payload of multiple terminals can be scheduled in one DL Payload area and the HARQ-ACK of multiple terminals can be transmitted in one HARQ-ACK area.
