[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 (RU), the number of repetitions, and the number of time slots and symbols occupied by one RU.

[0140] Number of resources (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 RU number of NPUSCH

[0142] Number of retransmissions (N Rep ), a row in Table 2 is indicated by the repetition number field (Repetition Number field) carried in DCI format N0.

[0143] Table 2 NPUSCH repetition times

[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 occupied by 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 an RU of single-tone transmission may 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 may be as shown in Table 4.

[0149] Table 4

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

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

[0152] For 15kHz, I SC =0-11, indicating the case of single-carrier transmission, where the subcarrier positions are 0-11 in one-to-one correspondence; I SC =12-15, corresponding to the multi-carrier transmission with 3 subcarriers, and a total of 4 positions; and so on, I SC =18, the corresponding subcarrier is 12 multi-carrier transmission, and there is 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) may be determined in the following manner: MCS Carried by the MCS field in the DCI, the MCS sub-segment is mapped as shown in Table 6.

[0154] Table 6

[0155] According to Table 6, when the modulation order supported by NPUSCH format 1 of single-carrier transmission is 1 or 2, the corresponding modulation modes are Pi / 2-BPSK and Pi / 4-QPSK respectively.

[0156] For multi-carrier transmission, the MCS is determined as follows: MCS The modulation and coding field in the DCI is used to carry the TBS. The base station (eNB) indicates this field to allow the terminal to determine the TBS. The modulation mode of multi-carrier transmission is fixed to QPSK.

[0157] In some embodiments, TBS is based on the parameters (I TBS , I RU ) and determine by table lookup, where I RU Indicated by the resource unit field. For single carrier transmission, I TBS By using I MCS Look up the table to determine that for multi-carrier transmission, I TBS =I MCS .

[0158] Table 7 NPUSCH TBS table

[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 L = 1 for single carrier transmission and L = min(4, ceil(Nrep / 2)) for multi-carrier transmission.

[0160] The resource mapping method is as follows: mapping is performed in the order of frequency domain first and time domain second. The modulated symbols are mapped to N Slot After time slots, this N Slot The time slots are repeated M_NPUSCH_identical-1 times. Then the next N Slot Slots, and then continue to repeat until Mrep×Nru×N_UL_slot time slots are mapped. and N slot The values ​​are as follows:

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

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

[0163] After NPUSCH is continuously transmitted for 256 milliseconds (ms), a 40ms uplink gap (UL gap) is inserted, and then NPUSCH transmission continues.

[0164] In some embodiments, the demodulation reference signal (DMRS) sequence of a single carrier transmission is generated based on a pseudo-random sequence, which can be as shown in FIG1D. shown.

[0165] In some embodiments, the DMRS of multi-carrier transmission is transmitted through a low-PAPR sequence (Low-PAPR Sequence), which can be as shown in FIG. 1E. u (n) = e jαn e jφ(n)π / 4 ,0≤n≤N RUBased on the formula in FIG. 1E , it can be seen that for multi-carrier transmission, each subcarrier includes a 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 may be as shown in Table 9.

[0169] Table 9

[0170] In addition, DMRS base sequence generation also supports group hopping and sequence hopping. Unlike NR PUSCH, NPUSCH DMRS group-sequence hopping needs to be enabled or disabled at the same time. The specific calculation formula is as follows: in, The definitions of are shown in Table 10.

[0171] Table 10

[0172] Optionally, the value of the group hopping type (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, so 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, it takes the value 0;

[0174] In some embodiments, the time domain 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). In addition, for multi-carrier transmission, the DMRS is distributed on each subcarrier.

[0177] FIG2 is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information processing method for an information processing system 100, and the method includes:

[0178] Step S2101: The network device sends 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 the DMRS.

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

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

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

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

[0185] Exemplarily, the first information includes a port number or code indicating a 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 a DMRS port and / or DMRS sequence used by the terminal; or, the first information may be used by the terminal to determine a DMRS port and / or DMRS sequence used.

[0187] In some embodiments, the first information is used to display, indicate and / or configure 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 the first information to the first terminal, including: the network device sends a first signaling to the first terminal, where the first signaling includes the first information.

[0189] Optionally, the first signaling includes: 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 a DMRS port and / or DMRS sequence used by the terminal; and DCI format N0 is used to indicate a 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 predetermined field in DCI format N0 may be used to indicate the DMRS sequence and / or DMRS port used by the terminal; the predetermined field may be a reserved field, a newly added field, or any field in DCI format N0.

[0192] Optionally, some bits of the coding and scaling (MCS) field in DCI format N0 are used to indicate the DMRS sequence and / or DMRS port used by the terminal. Exemplarily, some bits of the MCS field may be some high-order bits; for example, the MCS field includes a first bit and a second bit, the first bit being a high-order bit relative to the second bit; and the DMRS sequence and / or DMRS port used by the terminal may be indicated based on the first bit of the MCS field.

[0193] Optionally, some bits of the repetition number field in DCI format N0 are used to indicate the DMRS sequence and / or DMRS port used by the terminal. The some bits of the repetition number field may be any one or more bits of the repetition number field.

[0194] Optionally, some bits of the resource assignment field in DCI format N0 are used to indicate the DMRS sequence and / or DMRS port used by the terminal. The some bits of the resource assignment field may be any one or more bits of the resource assignment field.

[0195] Optionally, some bits of the subcarrier indication field in DCI format N0 are used to indicate the DMRS sequence and / or DMRS port used by the terminal. The some bits of the subcarrier indication field may 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] Exemplarily, the first field in the first signaling carries first information and the second field carries first information; the first information carried by the first field is used to indicate the DMRS sequence used by the terminal; the second information carried by the second field is used to indicate the DMRS port used by the terminal.

[0198] Exemplarily, 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 the DMRS port used by the terminal are jointly indicated by the same first information in the first signaling. The DMRS sequence and the DMRS port used by the terminal are jointly indicated by the same first information in the first signaling.

[0200] Exemplarily, the first signaling carries the first information or a certain field, which 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 a DMRS can be performed at different stages than the first information used by the terminal to determine a DMRS sequence and / or DMRS port. The first information used by the terminal to determine a DMRS can refer to the information used to determine multiple orthogonal DMRS ports and / or multiple orthogonal DMRS sequences. The first information used for the terminal's rooftop DMRS sequence and / or DMRS port can refer to the information used to determine 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 based on its function at different stages. The first sub-information is used by the terminal to determine the DMRS port and / or DMRS sequence to be used for orthogonality, while 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 can be, for example, a DMRS indication, a DMRS port indication, or a DRS sequence indication.

[0203] In some optional embodiments, a communication device determines an OCC sequence. The communication device may be a terminal or a network device.

[0204] Optionally, the OCC sequence may be the OCC sequence corresponding to the NPUSCH of the terminal. Exemplarily, the NPUSCH of different terminals corresponds to different OCC sequences, and the OCC sequence can be used to implement multiplexing and sending of NPUSCH by multiple terminals (or multiple users) on the same time-frequency resources. For example, when different terminals send NPUSCH, the NPUSCH of the terminal can be weighted using the OCC sequence corresponding to the NPUSCH of the terminal, and each terminal can send its own weighted NPUSCH to the network device on the same time-frequency resources. In addition, when the network device receives the weighted NPUSCH sent by each terminal on the same time-frequency resource, it can determine the NPUSCH of each terminal based on the OCC sequence corresponding to the NPUSCH of each terminal, so as to implement multiplexing and sending of NPUSCH by multiple terminals on the same time-frequency resources.

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

[0206] Optionally, the protocol preset form may be an existing form in the protocol or a newly added form; the form may be one or more.

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

[0208] Table 12 OCC length or the number of multiplexed UEs is 2

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

[0210] Table 13 OCC length or the number of multiplexed UEs is 4

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

[0212] Table 14 OCC length or the number of multiplexed UEs is 8

[0213] Exemplarily, the terminal may map different OCC sequence values ​​for symbols used for NPUSCH transmission based on the protocol preset tables such as Table 12, Table 13, or Table 14.

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

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

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

[0217] For example, the OCC sequence is a cyclically shifted sequence. When the OCC sequence is a cyclically shifted sequence, one of the OCC sequences can be first determined as a base sequence, and then cyclically shifted based on the base sequence to obtain M-1 sequences, where the M OCC sequences are mutually orthogonal.

[0218] For example, assume that the OCC sequence corresponding to one of the terminals is determined to be 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).

Exemplarily, the terminal determines the OCC sequence value corresponding to the OCC sequence index based on the OCC sequence index carried in the first information; the DMRS symbol coverage uses the same OCC sequence value as the data symbol. That is, the DMRS sequence can be the same as the OCC sequence.

[0231] Exemplarily, within a time slot, the terminal determines that the DMRS symbol covers the same OCC sequence value as that of the data symbol corresponding to the time slot where the DMRS symbol is located when OCC multiplexing is performed.

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

[0236] Exemplarily, the first information carries at least one OCC sequence index, and the terminal may determine a 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 a DMRS sequence based on the first information and mapping information, where the mapping information is used to indicate a mapping relationship between different OCC sequence indices and different DMRS sequences.

[0239] Optionally, the terminal determines a DMRS port and / or sequence based on the first information and mapping information. The mapping information is used to indicate a mapping relationship between different OCC sequence indices, different DMRS ports, and different DMRS sequences.

[0240] Exemplarily, the first information carries at least one OCC sequence index, and the terminal may determine a 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.

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

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

[0245] In some optional embodiments, before step S2102, the terminal may further include: determining the first information based on an instruction or configuration of the network device. Optionally, the terminal receives a first signaling sent by the network device, and determines the first information based on the first signaling.

[0246] In some optional embodiments, before step S2102, the following step may be included: the terminal determines the 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 determines the orthogonal DMRS port based on the frequency domain OCC, which may include: the terminal determines a first length based on the frequency domain OCC, wherein the first length is the sequence length of the DMRS for frequency domain OCC; and determines the DMRS port based on the first length.

[0249] Exemplarily, 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 example, 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] Exemplarily, 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 a protocol agreement, a network device configuration, and a network device indication. For example, when the second value is 6 or 12, and the number of subcarriers corresponding to the frequency-domain OCC is 6 or 12, the first length may be based on a protocol agreement or a network device indication; for example, the first length is 2 according to the protocol agreement.

[0251] Exemplarily, the terminal determines the orthogonal DMRS ports based on the frequency domain OCC, which may include: determining that the OCC sequence value j corresponding to the subcarrier x occupied by the DMRS meets the first condition; wherein the first condition is j = x mod L, the mod function is a remainder function, and L is the 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 are OCC multiplexed. Different users use different OCC sequence values ​​for the frequency-domain DMRS OCC sequence. The OCC sequence value used by user m for NPUSCH transmission, subcarrier i (i is the relative position among the S allocated subcarriers), 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.

The at least two first frequency domain resources are used by different DMRS ports, and the different DMRS ports are orthogonal DMRS ports.

[0255] Exemplarily, the same offset value is used between two adjacent first frequency domain resource positions in at least two first frequency domain resource positions. For example, 0, 2, 4, 6, and 8 are used as frequency domain resources for port 1, and 1, 3, 5, 7, and 9 are used as frequency domain resources for port 2. The frequency domain resources of port 1 and port 2 are FDM. In this case, the offset value between frequency domain resources 1 and 2 is the same, and the offset value between frequency domain resources 2 and 3 is the same; however, the offset value between frequency domain resources 1 and 3 is different.

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

[0259] Exemplarily, 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; wherein M can be 1, or M is the number of orthogonal ports determined by other DMRS orthogonal port methods; L is the OCC length.

[0262] Exemplarily, when the terminal determines the DMRS port based on the timing OCC, it may extend a symbol in the time domain, for example, using the adjacent symbol of the current symbol as the OCC symbol to generate a dual-symbol DMRS.

[0263] Exemplarily, the time domain position of the dual-symbol DMRS is determined by at least one of the following: based on protocol agreement; based on network device configuration; and based on network device indication.

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

In this way, after receiving the second information sent by the network device, the terminal can know the first length, the number of first frequency domain resources, the time domain position of the two-symbol DMRS, and / or the OCC sequence corresponding to the NPUSCH based on the second information.

[0397] The present disclosure relates to an information processing method, which is executed by a communication device, which includes a terminal or a network device. The method includes:

[0398] In some embodiments, for DMRS orthogonal design under OCC multiplexing under NPUSCH format 1 of 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 may be a transport block containing a DMRS symbol, or a DMRS sequence corresponding to a time slot containing a DMRS symbol. For example, as shown in FIG5A , the DMRS of 3.75 kHz SCS NPUSCH format 1 is located on symbol 4.

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

[0401] The first method is to achieve DMRS orthogonality based on different DMRS ports.

[0402] Optionally, the multiple DMRS ports are determined by at least one of the following methods:

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

[0404] Exemplarily, when the number of subcarriers is 3, the OCC length is determined to be 3.

[0405] For example, for cases where the number of subcarriers is 6 or 12, the OCC length can be determined by protocol agreement, or configured or indicated by a base station (e.g., gNB). For example, the protocol presets the OCC length to 2; or the protocol stipulates that the OCC length for DMRS frequency-domain OCC is determined based on the number of OCC multiplexed users / the maximum number of OCC multiplexed users / the OCC length / the 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 may be the first length in the previous embodiment.

[0407] For example, assuming that the DMRS OCC length is 4 (i.e., the number of multiplexed users is 4), a possible determination of the orthogonal DMRS port is shown in Figure 5C below: There are up to 4 users for OCC multiplexing, and different users use different orthogonal codes for the use of frequency-domain DMRS OCC sequences. The OCC sequence value used by subcarrier i (i is the relative position among the allocated S subcarriers) used by user m for NPUSCH transmission is Wm(j), where j = i mod L; the mod function is the remainder function, and L is the OCC length.

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

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

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

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

[0412] Exemplarily, 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; wherein, 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 a first frequency domain resource location based on the number of the first frequency domain resources; the first frequency domain resource locations include a plurality of first frequency domain resource locations, and the plurality of frequency domain resource locations are separated by the same frequency domain offset. The plurality of different first DMRS frequency domain resource locations are used as a plurality of DMRS ports. For example, as shown in FIG5D , port #1 and port #2 are orthogonal.

[0414] Optionally, this method is applicable to a method with 6 or 12 subcarrier numbers; or, it is also applicable to a method with other multi-carrier numbers.

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

[0416] Optionally, the communication device introduces dual-symbol DMRS for NPUSCH format 1, where the newly added DMRS can be located on symbol 2 or symbol 4. The time domain position of the newly added DMRS can be determined by protocol agreement or configured by the gNB.

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

[0418] Optionally, the protocol presets a DMRS port indication table, as shown in the DMRS design method of PUSCH DMRS in Table 15.

[0419] Table 15 PUSCH DMRS parameter configuration type 1

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

[0421] Optionally, if only frequency domain OCC multiplexing is used, DMRS may use the same OCC sequence as data symbols for OCC multiplexing. Here, the same OCC sequence may refer to the same OCC sequence value, the same OCC length, and / or the same OCC sequence index.

[0422] Optionally, for DMRS time domain OCC and / or frequency domain OCC, the OCC code is generated in one of the following ways: based on a protocol preset table OCC sequence table and / or base station (e.g., gNB) configuration or instruction; the protocol preset table may be an existing table or a newly added table, and the table may be one or more. A possible protocol preset table is as follows:

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

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

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

[0426] Here, the number of multiplexed UEs may refer to the number of multiplexed users.

[0427] Optionally, the OCC sequence is determined based on a protocol preset sequence generation method and / or a 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, and s(k) = exp(j*2pi*k / M); where M is the code length; and for the kth value of sequence#i, s(k) = s((k+i)modM). That is, first determine one of the sequences (e.g., sequence#0, with a sequence length of M). The remaining M-1 sequences can be derived based on cyclic shifts of sequence#0, thereby constructing an orthogonal sequence.

[0429] Optionally, any two OCC sequences used by UEs that reuse the same time-frequency resource satisfy at least one of the following constraints: different OCC sequences are orthogonal; and the mutual correlation between different OCC sequences is very low (for example, less than a first threshold).

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

[0431] Optionally, different DMRS ports meet the following characteristics: different DMRS ports are orthogonal to each other.

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

[0433] Optionally, for the generation of DMRS, different UEs multiplexed on the same block of time-frequency resources may 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] Optionally, in this manner, the terminal no longer expects the base station (eg, eNB) to configure cell-specific parameters; for example, three-subcarrier or six-subcarrier cyclic shifts (threeTone-CyclicShift and / or sixTone-CyclicShift).

[0435] In some embodiments, the DMRS sequence and / or DMRS port of different UEs is determined by at least one of the following methods: a base station (e.g., an eNB) directly configures or indicates parameters related to the DMRS sequence and / or DMRS port. For example, the configuration may be performed by UE-dedicated semi-static signaling or indicated via DCI format N0.

[0436] Optionally, the protocol predefines a mapping relationship between the cyclic shift of a DMRS port and / or DMRS sequence and an indication index. For example, the protocol predefines a mapping table between the indication index and the DMRS port and / or DMRS sequence; the index may be, for example, an OCC sequence miniature. Optionally, different numbers of subcarriers may have separate mapping relationships / mapping tables.

[0437] Optionally, for orthogonal DMRS sequences, the terminal implicitly determines the DMRS sequence and / or DMRS port using the OCC sequence index, based 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, or can be preset by a protocol, such as a protocol-preset association table. Optionally, the OCC sequence index can be determined by configuration or instruction from the eNB.

[0438] In some embodiments, for the solution of indicating through DCI format N0, at least one of the following design methods 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: The high-order N bits of the MCS are used to indicate the OCC sequence generation related parameters and / or DMRS ports.

[0442] Case 2: The OCC sequence and / or DMRS port are indicated by a portion of the repetition number. In this case, the actual number of repetitions can be determined as follows: Actual number of repetitions = number of repetitions indicated by the gNB * OCC length;

[0443] Case 3: The OCC sequence and / or DMRS port are indicated by using some bits of the resource assignment field. The number of RUs occupied by actual transmission in this method is determined in the same way as above.

[0444] Case 4: The OCC sequence and / or DMRS port are indicated through some bits of the subcarrier indication field.

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

[0446] In some embodiments, a combination of DMRS ports and DMRS sequences can be considered to achieve DMRS orthogonality. Optionally, based on this approach, up to M*N orthogonally multiplexed 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 DMRS sequence and DMRS port can be indicated differently. For example, the terminal can determine the cyclic shift information related to DMRS sequence generation through RRC semi-static signaling and determine the DMRS port information through DCI. Alternatively, the DMRS port and DMRS sequence cyclic shift configuration can be present in the same table, with a single index jointly indicating the DMRS port and DMRS sequence.
