[0139] In some embodiments, for time-domain resource allocation, the time-domain resources occupied by NPUSCH transmission include the following parameters: the number of Resource Units (RUs), the number of repetitions, and the number of slots and symbols occupied by one RU.

[0140] Resource quantity (N) RU A row in Table 1 is indicated by the resource assignment field in the Downlink Control Information (DCI) format N0.

[0141] Table 1 Number of RUs in NPUSCH

[0142] Number of retransmissions (N) Rep The repetition number field carried in DCI format N0 indicates a row in Table 2.

[0143] Table 2 Number of repetitions of NPUSCH

[0144] The number of time slots and symbols occupied by an RU is determined by the terminal by looking up the RU table based on the number of allocated subcarriers for multi-tone transmission; for single-tone transmission, the number of time slots of an RU is fixed at 16.

[0145] In some embodiments, for frequency domain resource allocation, the sub-carrier space (SCS), number of time slots, and number of symbols corresponding to one RU of single-tone transmission can be as shown in Table 3.

[0146] Table 3

[0147] For 3.75kHz SCS:I SC =0…47, occupying one subcarrier in the frequency domain; for 5kHz SCS: Isc=0…11, occupying one subcarrier in the frequency domain.

[0148] In some embodiments, for frequency domain resource allocation, the SCS, number of time slots, and number of symbols corresponding to one RU of multi-tone transmission can be as shown in Table 4.

[0149] Table 4

[0150] As shown in Table 5, rows 12-18 are used for multi-tone frequency domain resource allocation.

[0151] Table 5 shows the subcarriers allocated for 15kHz NPUSCH.

[0152] For 15kHz, I SC =0-11 indicates the case of single-carrier transmission, with subcarrier positions corresponding one-to-one from 0 to 11; I SC =12-15, corresponding to multi-carrier transmission with 3 subcarriers, with a total of 4 positions; and so on, I SC =18, corresponding to a multi-carrier transmission with 12 subcarriers, and a total of 1 position; I SC =19-63, the position is reserved.

[0153] In some embodiments, for single-carrier transmission, the modulation and coding scheme (MCS) can be determined in the following manner; MCS The MCS sub-segment is carried by the MCS field in the DCI and mapped to the values ​​shown in Table 6.

[0154] Table 6

[0155] As shown in Table 6, when the modulation order supported by NPUSCH format 1 for single-carrier transmission is 1 or 2, the corresponding modulation methods are Pi / 2-BPSK and Pi / 4-QPSK, respectively.

[0156] For multi-carrier transmission, the MCS is determined in the following way: I MCS The modulation and coding field in the DCI is used to carry the signal. The base station (eNB) uses this field to enable the terminal to determine the TBS; the modulation scheme for multi-carrier transmission is fixed as QPSK.

[0157] In some embodiments, TBS is based on parameter (I) TBS I RU And determine by looking up the table, where I RU This is indicated through the resource unit field. For single-carrier transmission, I TBS By using I MCS According to the table, for multi-carrier transmission, I TBS =I MCS .

[0158] Table 7. TBS Table of NPUSCH

[0159] In some embodiments, the redundancy version (RV) of NPUSCH is determined as follows: 1 bit, determined by the redundancy version field in DCI; Rv(j) = 2*mod(rv_DCI+j,2), where j = 0,1,…,Nrep / L-1; where, for single-carrier transmission, L = 1, and for multi-carrier transmission, L = min(4,ceil(Nrep / 2)).

[0160] The resource mapping method is as follows: mapping is performed in the order of frequency domain first, then time domain. The modulated symbols are mapped to N. Slot After one time slot, this N Slot Each time slot continues to repeat M_NPUSCH_identical-1 times. Then, the mapping continues for the next N. Slot This process is repeated for each slot until all slots (Mrep×Nru×N_UL_slot) are mapped. and N slot The possible values ​​are as follows:

[0161] For a 3.75kHz SCS in single-carrier transmission, assuming a transport block (TB) is mapped to one RU, each RU occupies 16 time slots, and is repeated 6 times, with rv_DCI = "0", then the mapping method is as shown in Figure 1B.

[0162] For a 15kHz SCS in multi-carrier transmission, assuming one TB is mapped to three RUs, each RU occupies four time slots, and the process is repeated four times, with rv_DCI = "0", then the mapping method is as shown in Figure 1C.

[0163] After 256 milliseconds (ms) of continuous NPUSCH transmission, a 40ms uplink interval (UL gap) is inserted before NPUSCH transmission continues.

[0164] In some embodiments, the demodulation reference signal (DMRS) sequence for single-carrier transmission is generated based on a pseudo-random sequence, as shown in Figure 1D. As shown.

[0165] In some embodiments, multi-carrier DMRS can be transmitted via a low-PAPR sequence, as shown in Figure 1E. u (n)=e jαn e jφ(n)π / 4 ,0≤n≤N RUAs shown in the formula in Figure 1E, for multi-carrier transmission, each subcarrier contains DMRS.

[0166] Optionally, the cyclic shift alpha(α) is determined as shown in Table 8. It should be noted that the cyclic shift parameter is a cell-specific parameter.

[0167] Table 8 Definition of α

[0168] Optionally, the phase of the base sequence can be as shown in Table 9.

[0169] Table 9

[0170] Furthermore, DMRS base sequence generation also supports group hopping and sequence hopping. Unlike NR PUSCH, NPUSCH DMRS group-sequence hopping requires both enabling and disabling. The specific calculation formula is shown below: in, The definition is shown in Table 10.

[0171] Table 10

[0172] Optionally, the group hop pattern parameter fgh(n') is related to the slot index. For multi-carrier transmission, the DMRS sequence is distributed in the frequency domain, and the value of n' is the value of the current slot. For single-carrier transmission, the DMRS sequence is distributed in the time domain; therefore, the value of n' is the value of the first slot among multiple RUs. Specifically, the formula for calculating fgh(n') is as follows:

[0173] Optionally, the parameter fss is generated by the following formula, where Δ ss ∈{0,1,...,29} is given by the cell-specific higher-layer parameter groupAssignmentNPUSCH. If not configured, the value is 0.

[0174] In some embodiments, the temporal resource location of the DMRS is determined by Table 11.

[0175] Table 11

[0176] As shown in Figure 1F, for 3.75kHz SCS NPUSCH format 1, the DMRS is located on symbol 4; for 15kHz SCS NPUSCH format 1, the DMRS is located on symbol 3 (one slot in NPUSCH occupies 7 symbols). Furthermore, for multi-carrier transmission, the DMRS is distributed across each subcarrier.

[0177] Figure 2 is an interactive schematic diagram illustrating an information processing method according to an embodiment of the present disclosure. As shown in Figure 2, the present disclosure relates to an information processing method used in an information processing system 100, the method comprising:

[0178] Step S2101: The network device sends the first information to the terminal.

[0179] In some embodiments, the terminal receives first information sent by the network device.

[0180] In some embodiments, the first information is used by the terminal to determine DMRS.

[0181] In some embodiments, the first information carries an index; the index is used to indicate the corresponding DMRS port and / or DMRS sequence.

[0182] Optionally, the index can be any string or number, etc.

[0183] Optionally, the index can be an OCC sequence index; the OCC sequence index can be used to indicate the OCC sequence value. For example, the DMRS sequence is the same as the OCC sequence, or the DMRS port corresponds to the OCC sequence. For example, different OCC sequence indices correspond to different DMRS sequences and / or DMRS ports. After receiving the first information, the terminal can determine the DMRS port and / or DMRS sequence based on the OCC sequence index carried in the first information.

[0184] In some embodiments, the first information may be used to indicate the DMRS port and / or DMRS sequence, or the first information may be used to configure the DMRS port and / or DMRS sequence.

[0185] For example, the first information includes a port number or code indicating the DMRS port, and / or a DMRS sequence, and / or a DRMS ​​sequence value, etc.

[0186] In some embodiments, the first information may be used to indicate the DMRS port and / or DMRS sequence used by the terminal; or, the first information may be used by the terminal to determine the DMRS port and / or DMRS sequence used.

[0187] In some embodiments, the first information is used to display the DMRS sequence and / or DMRS port used by the terminal; or, the first information is used to indicate the OCC sequence index of the NPUSCH used by the terminal.

[0188] In some embodiments, the network device sends first information to the first terminal, including: the network device sends first signaling to the first terminal, the first signaling including the first information.

[0189] Optionally, the first signaling may include: UE-dedicated semi-static signaling, or DCI. Optionally, the DCI may be DCI format N0.

[0190] Optionally, UE-specific semi-static signaling is used to configure the DMRS port and / or DMRS sequence used by the terminal; DCI format N0 is used to indicate the DMRS port and / or DMRS sequence used by the terminal.

[0191] Optionally, a new field is added to DCI format N0 to indicate the DMRS sequence and / or DMRS port used by the terminal. Alternatively, a pre-defined field in DCI format N0 can be used to indicate the DMRS sequence and / or DMRS port used by the terminal; this pre-defined field can be a reserved field in DCI format N0, a newly added field, or any field.

[0192] Optionally, a portion of the bits in the Encoding and Modulation (MCS) field of DCI format N0 is used to indicate the DMRS sequence and / or DMRS port used by the terminal. For example, the portion of the bits in the MCS field may be a high-order bit; for instance, the MCS field includes a first bit and a second bit, with the first bit being a high-order bit relative to the second bit; the first bit of the MCS field can be used to indicate the DMRS sequence and / or DMRS port used by the terminal.

[0193] Optionally, a portion of the bits in the Repetition number field of DCI format N0 is used to indicate the DMRS sequence and / or DMRS port used by the terminal. This portion of the bits in the Repetition number field can be any one or more bits from the Repetition number field.

[0194] Optionally, a portion of the bits in the Resource Assignment field of DCI format N0 is used to indicate the DMRS sequence and / or DMRS port used by the terminal. This portion of the bits in the Resource Assignment field can be any one or more bits of the Resource Assignment field.

[0195] Optionally, a portion of the bits in the Subcarrier indication field of DCI format N0 is used to indicate the DMRS sequence and / or DMRS port used by the terminal. This portion of the bits in the subcarrier indication field can be any one or more bits of the subcarrier indication field.

[0196] In some embodiments, the network device indicates the DMRS sequence and DMRS port used by the terminal through different first information. Optionally, the DMRS sequence and DMRS port used by the terminal are indicated through different first information.

[0197] For example, in the first signaling, the first field carries first information and the second field carries first information; the first information carried in the first field is used to indicate the DMRS sequence used by the terminal; the second information carried in the second field is used to indicate the DMRS port used by the terminal.

[0198] For example, UE-specific semi-static signaling is used to indicate the DMRS sequence used by the terminal, and DCI format N0 is used to indicate the DMRS port used by the terminal; or, DCI format N0 is used to indicate the DMRS sequence used by the terminal, and UE-specific semi-static signaling is used to indicate the DMRS port used by the terminal.

[0199] In some embodiments, the DMRS sequence and DMRS port used by the terminal are jointly indicated by the same first information in the first signaling.

[0200] For example, the first signaling may carry first information or a field that may simultaneously indicate the DMRS sequence and / or DMRS port used by the terminal.

[0201] In some embodiments, the first information used by the terminal to determine the DMRS and the first information used by the terminal to determine the DMRS sequence and / or DMRS port can be performed at different stages; wherein the first information used by the terminal to determine the DMRS can refer to the terminal determining multiple orthogonal DMRS ports and / or multiple orthogonal DMRS sequences; when the first information is used by the terminal to determine the DMRS sequence and / or DMRS port, it can refer to the terminal determining the DMRS sequence and / or DMRS port to be used. Of course, in other embodiments, the first information is divided into first sub-information and second sub-information according to its function at different stages; the first sub-information is used by the terminal to determine the orthogonal DMRS ports and / or DMRS sequences, and the second sub-information is used by the terminal to determine the DMRS port and / or DMRS sequence to be used.

[0202] In some embodiments, the name of the first information is not limited, and it may be, for example, a DMRS indication, a DMRS port indication, or a DRS sequence indication.

[0203] In some alternative embodiments, the communication device determines the OCC sequence. This communication device may be a terminal or a network device.

[0204] Optionally, the OCC sequence can be the OCC sequence corresponding to the NPUSCH of a terminal. For example, different terminals may have different OCC sequences for their NPUSCH, which can be used to enable multiple terminals (or multiple users) to multiplex their NPUSCH transmission on the same time-frequency resource. For instance, when different terminals transmit their NPUSCH, they can use the OCC sequence corresponding to their NPUSCH to weight their NPUSCH, and each terminal can transmit its weighted NPUSCH to the network device on the same time-frequency resource. Furthermore, when the network device receives the weighted NPUSCH transmitted by each terminal on the same time-frequency resource, it can determine the NPUSCH of each terminal based on the OCC sequence corresponding to each terminal's NPUSCH, thereby enabling multiple terminals to multiplex their NPUSCH transmission on the same time-frequency resource.

[0205] In some embodiments, the terminal determines the OCC sequence corresponding to the NPUSCH by at least one of the following: determining the OCC sequence based on a protocol preset table; determining the OCC sequence based on the configuration of the network device; determining the OCC sequence based on an instruction from the network device; and determining the OCC sequence based on a protocol preset sequence generation method. Optionally, the sequence length of the determined OCC sequence is a second length.

[0206] Optionally, the default table in the protocol can be an existing table in the protocol or a newly added table; there can be one or more tables.

[0207] For example, a protocol preset table may be shown in Table 12.

[0208] Table 12 shows that the OCC length or the number of reused UEs is 2.

[0209] For example, a protocol preset table may be shown in Table 13.

[0210] Table 13 shows that the OCC length or the number of reused UEs is 4.

[0211] For example, a protocol preset table may be shown in Table 14.

[0212] Table 14 shows that the OCC length or the number of reused UEs is 8.

[0213] For example, the terminal can preset tables such as Table 12, Table 13, or Table 14 above to map different OCC sequence values ​​for symbols used in NPUSCH transmission.

[0214] For example, the terminal determines the OCC sequence for NPUSCH transmission based on the protocol preset table and OCC sequence index. For example, as shown in Table 12, if the OCC sequence index is "0", the OCC sequence value can be [1,1], or if the OCC sequence index is "1", the OCC sequence value can be [1,-1].

[0215] For example, the terminal can determine the OCC sequence for NPUSCH transmission based on the instructions or configuration of the network device. For instance, the terminal receives first information sent by the network device, which indicates the OCC sequence index; the terminal determines the corresponding OCC sequence based on the OCC sequence index included in the first information and a protocol preset table. For example, the sequence value in the OCC sequence can be represented by W(j), j = 0, ..., L-1; where L can be used to represent the OCC length. As shown in Table 12, the sequence index corresponding to OCC sequence [1,1] is "0", and the sequence index corresponding to OCC sequence [1,-1] is "1".

[0216] Alternatively, the OCC sequence can be one of the following: Walsh sequence, Hamdard sequence, PN sequence, gold sequence, cyclic shift sequence, Zadoff-Chu sequence, etc.

[0217] For example, we will use the OCC sequence as a cyclic shift sequence. When the OCC sequence is a cyclic shift sequence, we can first determine one of the OCC sequences as the base sequence, and then perform cyclic shifting based on the base sequence to obtain M-1 sequences, wherein the M OCC sequences are mutually orthogonal to each other.

[0218] For example, suppose the OCC sequence corresponding to one of the terminals is determined as sequence#0 = [s(0), s(1), s(2), ..., s(k)], k = 0, ..., L-1; where L can be used to represent the sequence length of sequence#0, and s(k) = exp(j * 2pi * k / L). Furthermore, by performing a cyclic shift based on sequence#0, the OCC sequences corresponding to other terminals can be obtained as sequence#i, where i represents the OCC sequence corresponding to the i-th terminal. For the k-th value of sequence#i, we have: s(k) = s((k+i) mod L), where mod is the modulo function. Here, j is a complex number identifier, and pi is π.

[0219] In some embodiments, the OCC sequences corresponding to different terminals on the same resource are orthogonal.

[0220] In some embodiments, the cross-correlation between OCC sequences corresponding to different terminals on the same resource is less than or equal to a first threshold. Here, the cross-correlation between OCC sequences corresponding to different terminals is relatively low.

[0221] In some embodiments, the OCC sequences corresponding to different DMRS ports on the same resource are orthogonal; and / or the cross-correlation between the OCC sequences corresponding to different DMRS ports on the same resource is less than or equal to a first threshold.

[0222] In some embodiments, for the orthogonality of DMRS, different subcarriers employ different OCC sequence generation methods.

[0223] In some embodiments, for the generation of different DMRS sequences, different terminals multiplexed on the same time-frequency resource use different cyclic shift values.

[0224] Step S2102: The terminal determines DMRS.

[0225] In some embodiments, determining the DMRS by the terminal includes determining the DMRS port and / or the DMRS sequence. Optionally, the terminal determines a plurality of DMRS ports and / or a plurality of DMRS sequences for orthogonality.

[0226] In some embodiments, the DMRS corresponding to a terminal and other terminals in the same OCC multiplexing user group are orthogonal, and terminals in the same OCC multiplexing user group use the same time-frequency domain resources. Optionally, the same OCC multiplexing user group includes multiple terminals.

[0227] In some embodiments, the terminal determines DMRS based on first information.

[0228] Optionally, the first information includes the OCC sequence index used by the user in the same OCC multiplexing user group; based on the first information, determining the demodulation reference signal DMRS of the terminal includes: based on the OCC sequence index included in the first information, determining that the sequence value covered by the DMRS symbol is the same as the OCC sequence value used when the data symbol is multiplexed using orthogonal overlay code OCC.

[0229] Optionally, the terminal determines that the DMRS symbol uses the same OCC sequence value as the data symbol when performing OCC multiplexing; the first information is the OCC sequence index used by the terminal. For example, the terminal determines the OCC sequence value corresponding to the OCC sequence index based on the OCC sequence index carried in the first information; this DMRS symbol uses the same OCC sequence value as the data symbol. That is, the DMRS sequence can be the same as the OCC sequence.

[0230] For example, within an OCC multiplexing block, the terminal determines that the DMRS symbol overwrites the same OCC sequence value as when the data symbol is OCC multiplexed.

[0231] For example, within a time slot, the terminal determines that the DMRS symbol overlays the same OCC sequence value as the data symbol corresponding to the time slot where the DMRS symbol is located when performing OCC multiplexing.

[0232] For example, within an OCC multiplexing block, it is determined that the sequence value overlaid by the DMRS symbol is the same as the OCC sequence value when the data symbol is OCC multiplexed.

[0233] For example, within a time slot, it is determined that the sequence value covered by the DMRS symbol is the same as the OCC sequence value when the data symbol corresponding to the time slot where the DMRS symbol is located is OCC multiplexed. Here, it is determined that the sequence value covered by the DMRS symbol is the same as the OCC sequence value when the first data symbol is OCC multiplexed; the first data symbol is the data symbol corresponding to the time slot where the DMRS symbol is located.

[0234] Optionally, the sequence value covered by the DMRS symbol can be an OCC sequence value or a DMRS sequence value.

[0235] Optionally, the terminal determines the DMRS port based on the first information and the mapping information. This mapping information indicates the mapping relationship between different OCC sequence indices and different DMRS ports.

[0236] For example, if the first information carries at least one OCC sequence index, the terminal can determine the DMRS port corresponding to the at least one OCC sequence index based on the at least one OCC sequence index and the mapping information.

[0237] Optionally, the terminal determines the DMRS sequence based on the first information and the mapping information. This mapping information indicates the mapping relationship between different OCC sequence indices and different DMRS sequences.

[0238] For example, if the first information carries at least one OCC sequence index, the terminal can determine the DMRS sequence corresponding to the at least one OCC sequence index based on the at least one OCC sequence index and the mapping information.

[0239] Optionally, the terminal determines the DMRS port and / or sequence based on the first information and the mapping information. The mapping information indicates the mapping relationship between different OCC sequence indices and different DMRS ports and different DRMS ​​sequences.

[0240] For example, if the first information carries at least one OCC sequence index, the terminal can determine the DMRS port and / or DMRS sequence corresponding to the at least one OCC sequence index based on the at least one OCC sequence index and the mapping information.

[0241] Alternatively, different DMRS ports can be orthogonal, and different terminals in the same multiplexed user group can use different DMRS ports.

[0242] Optionally, the terminal can determine at least one DMRS port and / or at least one DMRS sequence through the first information and mapping information; the different DMRS ports can be orthogonal, or the different DMRS sequences can also be orthogonal.

[0243] Optionally, the mapping information may also indicate the mapping relationship between the DMRS port and the OCC sequence index and / or the frequency domain resource index of the FDM. The OCC sequence index includes a time-domain OCC index and a frequency-domain OCC index.

[0244] In some alternative embodiments, the mapping information is agreed upon by the protocol or preset by the protocol. For example, the protocol presets the mapping relationship between the first information and the DMRS sequence and / or the DMRS port; or, the protocol presets the relationship between an index and the DMRS sequence and / or the DMRS port, which may be an OCC sequence index.

[0245] In some optional embodiments, the process may further include, prior to step S2102: the terminal determining first information based on an instruction or configuration from the network device. Optionally, the terminal receives first signaling from the network device and determines the first information based on the first signaling.

[0246] In some alternative embodiments, before step S2102, the method may further include: the terminal determining first information based on a protocol agreement.

[0247] In some embodiments, the terminal determines orthogonal DMRS ports based on frequency domain OCC.

[0248] Optionally, the terminal determining the orthogonal DMRS port based on frequency domain OCC may include: the terminal determining a first length based on frequency domain OCC, wherein the first length is the sequence length of the DMRS performing frequency domain OCC; and determining the DMRS port based on the first length.

[0249] For example, when the number of subcarriers corresponding to the frequency domain OCC is a first value, the terminal determines the first length to be a first value. For instance, when the first value is 3, the number of subcarriers corresponding to the frequency domain OCC is 3, and the first length (i.e., OCC length) is 3.

[0250] For example, when the number of subcarriers corresponding to the frequency domain OCC is a second value, the first length is determined based on at least one of the following: protocol agreement, network device configuration, and network device indication. For example, the second value is 6 or 12; the number of subcarriers corresponding to the frequency domain OCC is 6 or 12, and the first length can be based on the protocol agreement or the network device indication; for example, according to the protocol agreement, the first length is 2.

[0251] For example, the terminal determines orthogonal DMRS ports based on frequency domain OCC, which may include: determining that the OCC sequence value j corresponding to the subcarrier x occupied by the DMRS satisfies a first condition; wherein, the first condition is j = x mod L, the mod function is a modulo function, and L is a first length; different DMRS ports correspond to different OCC sequences, and different OCC sequences are orthogonal to each other.

[0252] For example, up to four users can perform OCC multiplexing. For the use of frequency domain DMRS OCC sequences, different users use different OCC sequence values. The OCC sequence value used by user m for NPUSCH transmission is Wm(j), where j = i mod L.

[0253] In some embodiments, the terminal determines orthogonal DMRS ports based on frequency division multiplexing (FDM) resources.

[0254] Optionally, the terminal determines orthogonal DMRS ports based on Frequency Division Multiplexing (FDM) resources, which may include: determining the number of first frequency domain resources used for DMRS transmission; determining the locations of first frequency domain resources based on the number of first frequency domain resources; wherein the first frequency domain resource locations include at least two, and the at least two first frequency domain resource locations are FDM-enabled; and designating DMRS ports using at least two first frequency domain resources as orthogonal DMRS ports. These at least two first frequency domain resources are used by different DMRS ports, and these different DMRS ports are orthogonal DMRS ports.

[0255] For example, at least two adjacent first frequency domain resource locations have the same offset. For instance, 0, 2, 4, 6, 8 are the frequency domain resources of port 1, and 1, 3, 5, 7, 9 are the frequency domain resources of port 2; the frequency domain resources of port 1 and port 2 are FDM; in this case, the offset between frequency domain resources 1 and 2 is the same, and the offset between frequency domain resources 2 and 3 is the same; however, the offset between frequency domain resources 1 and 3 is different.

[0256] Optionally, the terminal determines the number of first frequency domain resources used for DMRS transmission, including: in the case of OCC multiplexing for NPUSCH transmission, determining the number of first frequency domain resources for DMRS, wherein the number of first frequency domain resources is less than the number of second frequency domain resources, and the number of second frequency domain resources is the number of frequency domain resources occupied by DMRS without OCC multiplexing.

[0257] Optionally, the terminal determines the number of first frequency domain resources used for DMRS transmission by at least one of the following: determining the number of first frequency domain resources for DMRS based on protocol agreement; determining the number of first frequency domain resources for DMRS based on network device configuration; and determining the number of first frequency domain resources for DMRS based on network device indication.

[0258] Optionally, the terminal determines the number of first frequency domain resources of DMRS based on the protocol agreement, including one of the following: the number of first frequency domain resources is a predetermined value as agreed in the protocol; or the number of first frequency domain resources is determined based on the number of OCC multiplexing users, the first length, the maximum number of OCC multiplexing users, or the sequence length of the OCC sequence as agreed in the protocol.

[0259] For example, the number of first frequency domain resources is the ratio of the number of subcarriers used for multi-carrier NPUSCH channel transmission to the first length; for example, the number of first frequency domain resources is: number of subcarriers / L; or, the number of first frequency domain resources is: subcarriers / L / M; where M can be 1, or M is the number of orthogonal ports determined by other DMRS orthogonal port methods; L is the OCC length.

[0260] In some embodiments, the terminal determines orthogonal DMRS ports based on time-domain OCC.

[0261] Optionally, the terminal determines the orthogonal DMRS port based on the time-domain OCC, which may include: determining the DMRS as a dual-symbol DMRS based on the protocol agreement; wherein different values ​​in the OCC sequence are mapped to different symbols in the dual-symbol DMRS; different OCC sequences are orthogonal to each other; and determining the orthogonal DMRS port based on the different OCC sequences corresponding to different DMRS ports.

[0262] For example, when a terminal determines the DMRS port based on timing OCC, it can extend the time domain by one symbol, such as using the adjacent symbol of the current symbol as the OCC symbol to generate a dual-symbol DMRS.

[0263] For example, the time-domain location of a dual-symbol DMRS is determined by at least one of the following: based on protocol conventions; based on network device configuration; and based on network device indication.

[0264] In some embodiments, the terminal determines the number of orthogonal DMRS ports supporting orthogonal multiplexed users that is less than or equal to a third value, based on different DMRS ports and different DMRS sequences. The third value is the product of a fourth value and a fifth value, where the fourth value is the number of orthogonal DMRS ports and the fifth value is the number of orthogonal DMRS sequences. Here, if the terminal supports the fourth value for the number of orthogonal DMRS ports and the terminal supports the fifth value for the number of orthogonal DMRS sequences, then the terminal can support a maximum of the third value (i.e., the product of the fourth and fifth values) of orthogonal multiplexed users with orthogonal DMRS ports. Of course, in other embodiments, the fourth value can be all the DMRS ports supported by the terminal; the fifth value can be all the DMRS sequences supported by the terminal.

[0265] In some alternative embodiments, the network device sends second information to the terminal, wherein the second information indicates at least one of the following: a first length, a first number of frequency domain resources, a two-symbol DMRS time-domain location, and an OCC sequence. Thus, after receiving the second information sent by the network device, the terminal can know the first length, the first number of frequency domain resources, the two-symbol DMRS time-domain location, and / or the OCC sequence corresponding to the NPUSCH, etc., based on the second information.

[0266] Optionally, the first length, the number of first frequency domain resources, the time domain position of the dual-symbol DMRS, and the OCC sequence mentioned above can be indicated by different second information, or by different fields or bits in the second information, etc.

[0267] Step S2103: The network device determines DMRS.

[0268] In some embodiments, the method by which the network device determines DMRS is similar to the method by which the terminal determines DMRS. The method by which the network device determines DMRS can be found in the above-described method by which the terminal determines DMRS, and will not be repeated here.

[0269] In step S2104, the terminal determines the DMRS port and / or DMRS sequence to be used.

[0270] In some embodiments, the terminal may determine the DMRS port and DMRS sequence used by the terminal from the orthogonal DMRS ports and / or DMRS sequences determined in step S2102.

[0271] In some embodiments, the terminal determines the DMRS port and / or DMRS sequence used by the terminal based on the first information.

[0272] Optionally, the terminal determines first information based on the first signaling sent by the network device; and determines the DMRS sequence and / or DMRS port used by the terminal based on the first information.

[0273] For example, the terminal can determine the DMRS port and / or DMRS sequence used by the terminal based on the content indicated by the aforementioned UE-specific semi-static signaling or DCI format N0.

[0274] For example, the terminal may determine the DMRS sequence and / or DMRS port based on the first information and the mapping information; wherein the mapping information is used to indicate the mapping relationship between the first information and the DMRS sequence and / or DMRS port.

[0275] Optionally, the terminal determines the DMRS sequence and / or DMRS port used by the terminal based on the protocol agreement.

[0277] In some embodiments, the method by which the network device determines the DMRS port and / or DMRS sequence used by the terminal is similar to the method by which the terminal determines the DMRS port and / or DMRS sequence used by the terminal. The method by which the network device determines the DMRS port and / or DMRS sequence used by the terminal is similar to the method by which the terminal determines the DMRS port and / or DMRS sequence used by the terminal, and will not be repeated here.

[0279] Optionally, the network device determines the DMRS sequence and / or DMRS port used by the terminal based on protocol agreements.

[0280] In step S2106, the terminal sends an NPUSCH based on OCC multi-user multiplexing to the network device based on DMRS.

[0397] This disclosure relates to an information processing method, executed by a communication device, which includes a terminal or a network device; the method includes:

[0398] In some embodiments, for DMRS orthogonal designs under OCC multiplexing in NPUSCH format 1 with single-tone or multi-tone transmission, the following approach is considered: DMRS symbols cover the same OCC sequence value as the data symbols.

[0399] Optionally, the OCC sequence value can be a transport block containing DMRS symbols, or the DMRS sequence corresponding to a time slot containing DMRS symbols. For example, as shown in Figure 5A, the DMRS for 3.75kHz SCS NPUSCH format 1 is located on symbol 4.

[0400] In some embodiments, for multi-tone transmission, orthogonality between DMRS of different UEs can be achieved in at least one of the following ways: orthogonality between DMRS of different UEs based on different DMRS ports; or orthogonality between DMRS of different UEs based on different DMRS sequences. Optionally, the UE can be a terminal.

[0401] The first method: Implement DMRS orthogonality based on different DMRS ports.

[0402] Optionally, multiple DMRS ports may be determined in at least one of the following ways:

[0403] Method 1: Determine the DMRS port based on frequency domain OCC.

[0404] For example, if the number of subcarriers is 3, the OCC length is determined to be 3.

[0405] For example, for cases with 6 and 12 subcarriers, the OCC length can be determined by a protocol-defined method, or configured or indicated by the base station (e.g., gNB). For instance, the protocol may default to an OCC length of 2; or the protocol may stipulate that the OCC length for frequency-domain OCC in DMRS is determined based on the number of OCC multiplexed users / maximum number of OCC multiplexed users / OCC length / number of OCC sequences. For example, as shown in Figure 5B, the DMRS for 15kHz SCS NPUSCH format 1 is located on symbol 3.

[0406] For example, the OCC length can be the first length in the previous embodiment.

[0407] For example, assuming the DMRS OCC length is 4 (i.e., the number of multiplexed users is 4), one possible determination of the orthogonal DMRS ports is shown in Figure 5C below: A maximum of 4 users perform OCC multiplexing. For the use of the frequency domain DMRS OCC sequence, different users use different orthogonal codes. The OCC sequence value used by user m for NPUSCH transmission on subcarrier i (where i is the relative position among the S allocated subcarriers) is Wm(j), where j = i mod L; the mod function is the modulo function, and L is the OCC length.

[0408] Method 2: Determine the DMRS port based on FDM resources.

[0409] Optionally, when the communication device performs OCC multiplexing for NPUSCH transmission, it determines the number of first frequency domain resources of DMRS, which is less than the number of second frequency domain resources; wherein, the number of second frequency domain resources is the number of resources occupied by the DMRS of users who do not perform OCC multiplexing.

[0410] Optionally, the communication device determines the number of first frequency domain resources of DMRS, and the method includes at least one of the following: determining the number of first frequency domain resources based on protocol agreement; determining the number of first frequency domain resources based on gNB configuration; and determining the number of first frequency domain resources based on gNB indication.

[0411] Optionally, the communication equipment determines the number of first frequency domain resources based on the protocol agreement, including: the number of first frequency domain resources is a preset value of the protocol; or, the number of first frequency domain resources is determined based on the number of OCC multiplexing users / OCC length / maximum number of OCC multiplexing users / number of OCC sequences (i.e., L).

[0412] For example, the number of first frequency domain resources = the number of subcarriers used for multi-carrier NPUSCH channel transmission / L / M, or the number of first frequency domain resources = the number of subcarriers used for multi-carrier NPUSCH channel transmission / L; where M can be 1, or the number of orthogonal ports determined by other DMRS orthogonal port methods; L is the OCC length.

[0413] Optionally, the communication device determines the location of a first frequency domain resource based on the number of first frequency domain resources; the first frequency domain resource location includes multiple locations, and the multiple frequency domain resource locations are spaced by the same frequency domain offset. Multiple different first DMRS frequency domain resource locations are used as multiple DMRS ports. For example, as shown in Figure 5D, port #1 and port #2 are orthogonal.

[0414] Optionally, this method is applicable to methods with 6 or 12 subcarriers; or, it is also applicable to other methods with multiple subcarriers.

[0415] Method 3: Determine the DMRS port based on time-domain OCC.

[0416] Optionally, the communication equipment introduces a dual-symbol DMRS for NPUSCH format 1, wherein the newly added DMRS can be located on symbol 2 or symbol 4, and the time domain location of the newly added DMRS can be determined by the protocol agreement or configured by the gNB.

[0417] Note: At least two of the above orthogonal methods (method 1, method 2, and method 3) can be used in combination.

[0418] Optionally, the protocol pre-sets a DMRS port indication table, as shown in Table 15, which illustrates the DMRS design of PUSCH DMRS.

[0419] Table 15 Configuration Type 1 of PUSCH DMRS Parameters

[0420] Alternatively, the OCC sequence can be determined based on at least one of the following methods:

[0421] Optionally, if only frequency-domain OCC multiplexing is used, DMRS can use the same OCC sequence as the data symbols for OCC multiplexing. Here, the same OCC sequence can mean that the OCC sequence values ​​are the same, the OCC length is the same, and / or the OCC sequence index is the same.

[0422] Optionally, for DMRS time-domain OCC and / or frequency-domain OCC, the OCC code is generated using one of the following methods: based on a protocol preset table OCC sequence table and / or base station (e.g., gNB) configuration or indication determination; the protocol preset table can be an existing table or a newly added table, and there can be one or more tables. A possible protocol preset table is shown below:

[0423] For example, one possible protocol preset table is shown in Table 12 above.

[0424] For example, one possible protocol preset table is shown in Table 13 above.

[0425] For example, one possible protocol preset table is shown in Table 14 above.

[0426] Here, the number of reused UEs can refer to the number of reused users.

[0427] Optionally, the OCC sequence is determined based on the protocol preset sequence generation method and / or the base station (e.g., eNB) configuration or indication; the protocol preset sequence may be at least one of the following: Walsh sequence, Hamdard sequence, PN sequence, gold sequence, cyclic shift sequence, and Zadoff-Chu sequence, etc.

[0428] For example, a possible cyclic shift sequence is as follows: sequence#0 = [s(0), s(1), s(2), ..., s(k)], where k = 0, ..., M-1, s(k) = exp(j*2pi*k / M); where M is the code length; for the k-th value of sequence#i, we have: s(k) = s((k+i)modM). That is, first determine one sequence (e.g., sequence#0, sequence length M), the remaining M-1 sequences can be obtained based on the cyclic shift of sequence#0, thus constructing orthogonal sequences.

[0429] Optionally, any two OCC sequences used by a UE that reuses the same time-frequency resources satisfy at least one of the following constraints: different OCC sequences are orthogonal; different OCC sequences have very low cross-correlation (e.g., less than a first threshold).

[0430] Optionally, for frequency domain DMRS OCC, different OCC sequence generation methods can be used for different numbers of subcarriers.

[0431] Alternatively, different DMRS ports may have the following characteristics: different DMRS ports are orthogonal to each other.

[0432] The second approach is to achieve DMRS orthogonality based on different DMRS sequences.

[0433] Optionally, for the generation of DMRS, different UEs multiplexed on the same time-frequency resource block can use different cyclic shifts (alpha). This method is applicable to at least one of the following numbers of subcarriers: 3, 6, or 12 subcarriers.

[0434] Alternatively, in this approach, the terminal no longer expects the base station (eNB) to configure cell-specific parameters, such as cyclic shifts of three or six subcarriers (three-Tone-CyclicShift and / or six-Tone-CyclicShift).

[0435] In some embodiments, the DMRS sequence and / or DMRS port of different UEs are determined by at least one of the following methods: by direct configuration or indication of parameters related to the DMRS sequence and / or DMRS port by the base station (e.g., eNB). For example, it may be configured by UE-dedicated semi-static signaling or indicated by DCI format N0.

[0436] Optionally, the protocol predefines the mapping relationship between the cyclic shift of DMRS ports and / or DMRS sequences and the indicator index. For example, the protocol predefines a mapping table between the indicator index and the DMRS ports and / or DMRS sequences; this index can be an OCC sequence abbreviated form, etc. Optionally, different numbers of subcarriers can have independent mapping relationships / mapping tables.

[0437] Optionally, for the orthogonal DMRS sequence, the terminal implicitly determines the DMRS sequence and / or DMRS port using the OCC sequence index, depending on the number of carriers. Different values ​​of the OCC sequence index are associated with the DMRS sequence and / or DMRS port; this association can be configured by the eNB through semi-static signaling or system messages; alternatively, this association can be preset by the protocol, such as through a pre-defined association table. Optionally, the OCC sequence index can be determined by the eNB's configuration or instruction.

[0438] In some embodiments, for schemes indicated via DCI format N0, at least one of the following design approaches may be considered:

[0439] Option 1: Introduce a new field to indicate the DMRS sequence and / or DMRS port.

[0440] Option 2: Reuse at least one of the following fields to indicate the DMRS sequence and / or DMRS port:

[0441] Case 1: Generate relevant parameters and / or DMRS port indications by using the high N bits of the MCS to generate the OCC sequence.

[0442] Scenario 2: Indication of the OCC sequence and / or DMRS port is made using a portion of the repetition number. In this method, the actual repetition number can be determined as follows: Actual repetition number = Repetition number indicated by gNB * OCC length;

[0443] Scenario 3: Indication of OCC sequence and / or DMRS port is made through partial bits of the Resource Assignment field. The actual number of RUs occupied by transmission is determined in the same way as above.

[0444] Case 4: Indication of OCC sequence and / or DMRS port via partial bits of the Subcarrier indication field.

[0445] Optionally, for the terminal to determine the DCI fields, when the terminal supports and reports support for OCC multiplexing, the terminal always uses at least one of the above methods to interpret the DCI fields; or, when the network side enables OCC multiplexing (based on explicit indication or implicit indication. Explicit indication, for example, indicating a 1-bit enable field in the RRC or system message; implicit indication, for example, configuring OCC multiplexing related parameters, such as OCC length, in the RRC or system message), the terminal interprets the DCI fields based on at least one of the above methods; otherwise, the traditional method is still used to interpret each DCI field. That is, for option 1, there is no newly introduced DMRS port and / or DMRS sequence indication field; for option 2, each field is still defined in the traditional way.

[0446] In some embodiments, a combination of DMRS ports and DMRS sequences can be considered to achieve orthogonal DMRS. Optionally, based on this method, a maximum of M*N orthogonal multiplexing users can be supported, where M is the total number of DMRS ports and N is the total number of orthogonal DMRS sequences.

[0447] Optionally, the indication methods for DMRS sequences and DMRS ports can be different. For example, the terminal determines the DMRS sequence and generates relevant cyclic shift information through RRC semi-static signaling; and determines the DMRS port information through DCI. Alternatively, the DMRS port and DMRS sequence cyclic shift configuration can also exist in the same table, using an index to jointly indicate the DMRS port and DMRS sequence.

[0448] In this embodiment of the disclosure, some or all of the steps and their optional implementations can be arbitrarily combined with some or all of the steps in other embodiments, or arbitrarily combined with the optional implementations in other embodiments.

[0449] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0450] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an Application-Specific Integrated Circuit (ASIC), and the functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), which can include a large number of logic gates.

In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an Application-Specific Integrated Circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be hardware circuits designed for artificial intelligence, which can be understood as ASICs, such as Neural Network Processing Units (NPUs), Tensor Processing Units (TPUs), and Deep Learning Processing Units (DPUs).
