[0034] The following explains some concepts and / or terms involved in an OCC determination method, apparatus, device, and storage medium provided in an embodiment of the present application.

[0035] 1. Block-wise spreading

[0036] In related protocols, in order to improve the terminal multiplexing capability and thus increase system capacity, an OCC-based block spread spectrum transmission method is introduced in Physical Uplink Control Channel (PUCCH) transmission.

[0037] For PUCCH format 3, block-spread transmission is supported only when interlace mapping is used, and 1 / 2 / 4 user multiplexing is supported only when a single interlace unit is configured.

[0038] For PUCCH format 4, 2 / 4 user multiplexing is supported, which is configured through the higher-layer parameter occ-Length, and the OCC sequence used is also configured through the higher-layer parameter occ-Index.

[0039] For block-based spread spectrum, different terminals are multiplied by different OCC sequences. The Fast Fourier Transform (FFT) transform properties are then used to enable different terminals to occupy different resource elements (REs) during frequency domain mapping after each Discrete Fourier Transform (DFT) transform. For example, terminal 0 occupies odd-numbered REs, and terminal 1 occupies even-numbered REs. This achieves a comb mapping effect and enables multi-user multiplexing.

[0040] 2. Physical Uplink Shared Channel (PUSCH) Demodulation Reference Signal (DMRS) port indication of DFT waveform

[0041] In NR systems, DMRS is used for channel estimation. Data channel DMRS can be categorized by DMRS configuration type 1 and DMRS configuration type 2, with both types supporting single-symbol and dual-symbol structures. For DFT-waveform PUSCH transmission, each user supports a maximum of one PUSCH data stream and only supports DMRS configuration type 1, corresponding to two code division multiplexing (CDM) groups and a maximum of eight ports.

[0042] The OCC determination method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0043] The present invention provides an OCC determination method, and Figure 2 shows a flow chart of the OCC determination method provided by the present invention. As shown in Figure 2, the OCC determination method provided by the present invention may include the following steps 201 and 202.

[0044] Step 201: The terminal obtains first information.

[0045] Step 202: The terminal determines OCC information according to the first information.

[0046] In the embodiment of the present application, the OCC information is associated with the transmission of the first signal. The first information includes at least one of the following:

[0047] DMRS information;

[0048] TDRA information;

[0049] SLIV information;

[0050] a time interval between a first signal and a second signal that schedules the first signal;

[0051] a resource allocation type of the first signal;

[0052] RU information;

[0053] OCC-related parameters indicated by the network-side device.

[0054] The transmission in the embodiments of the present application can be understood as sending or receiving.

[0055] In an embodiment of the present application, the terminal determines the OCC information based on the first information, and can flexibly determine the OCC information used to transmit the first signal, thereby realizing multiplexing based on the OCC information, thereby ensuring the orthogonality of multi-terminal multiplexing and improving the uplink transmission capacity.

[0056] Optionally, in an embodiment of the present application, the above-mentioned first information may be predefined, or agreed upon by a protocol, or preconfigured, or configured by a network-side device.

[0057] Optionally, in an embodiment of the present application, the above-mentioned first signal may include at least one of the following: a control channel, a data channel, a reference signal, etc.

[0058] Optionally, in an embodiment of the present application, the above-mentioned control channel may include at least one of the following: PUCCH, Physical Downlink Control Channel (PDCCH).

[0059] Optionally, in an embodiment of the present application, the above-mentioned data channel may include at least one of the following: PUSCH, Physical Downlink Share Channel (PDSCH).

[0060] Optionally, in an embodiment of the present application, the second signal may include at least one of the following: PDCCH, PDSCH.

[0061] For example, the time interval between the first signal and the second signal that schedules the first signal may be the interval K0 between the PUSCH and the PDCCH that schedules the PUSCH.

[0062] For example, the resource allocation type of the first signal may be a time domain resource allocation type of PUSCH, ie, mapping type A or B; or may be a frequency domain resource allocation type of PUSCH, ie, resource allocation type 0 or 1.

[0063] Optionally, in an embodiment of the present application, the above-mentioned reference signal may include at least one of the following: DMRS, Sounding Reference Signal (Sounding Reference Signal, SRS), Channel-State Information Reference Signal (Channel-State Information Reference Signal, CSI-RS).

[0064] Optionally, in an embodiment of the present application, the OCC information may include at least one of the following: an OCC sequence set, an OCC sequence, an OCC sequence index set, an OCC sequence index, an OCC sequence length set, an OCC sequence length, and OCC enabling information. The OCC enabling information is used to enable whether transmission of the first signal is based on the OCC information.

[0065] Exemplarily, the OCC information includes an OCC sequence, which is used for multiplexing PUSCHs corresponding to multiple terminals. In this case, the OCC sequence can be a time-domain TD-OCC sequence, for example, multiplexing based on repetition in the time domain; or the OCC sequence can be an OCC sequence used for block spread spectrum or similar block spread spectrum multiplexing, for multiplexing resources of different terminals in the frequency domain; or the OCC sequence includes a combination of the two. Of course, the OCC sequence can also be used for other forms of PUSCH multiplexing to achieve multiplexed transmission of PUSCHs of multiple terminals.

[0066] Optionally, in an embodiment of the present application, the above-mentioned DMRS information may be indicated through an antenna ports field in downlink control information (DCI), or configured through higher-layer parameters.

[0067] Optionally, in this embodiment of the present application, the DMRS information includes at least one of the following:

[0068] The indication value in the antenna port field (i.e., the value, or the value corresponding to the antenna port field indication bit);

[0069] DMRS port;

[0070] CDM group corresponding to the DMRS port;

[0071] Number of DMRS leading symbols;

[0072] The number of additional symbols for DMRS;

[0073] The number of occupied symbols of DMRS;

[0074] DMRS scrambling code identifier.

[0075] Optionally, in an embodiment of the present application, the number of additional symbols of the above-mentioned DMRS may be the number of additional symbols of the DMRS corresponding to the dmrs-AdditionalPosition parameter or the number of occupied symbols of the DMRS.

[0076] Optionally, in an embodiment of the present application, the number of occupied symbols of the DMRS may be the number of occupied symbols of the DMRS in a time domain unit (eg, a time slot).

[0077] Optionally, in this embodiment of the present application, the indication value in the antenna port field and the OCC information satisfy at least one of the following correspondences:

[0078] Each indicator value corresponds to an OCC information;

[0079] Each indication value corresponds to multiple OCC information;

[0080] Multiple indication values ​​correspond to the same OCC information;

[0081] Each set of indicator values ​​corresponds to one piece of OCC information.

[0082] Optionally, in an embodiment of the present application, when each indication value corresponds to multiple OCC information, the specific corresponding OCC information can be determined through other signaling, such as Radio Resource Control (RRC) signaling or Media Access Control-Control Element (MAC-CE) signaling or other DCI domains, or default agreed rules, or terminal selection.

[0083] Exemplarily, when multiple indicator values ​​correspond to the same OCC information, assuming there are 8 OCC sequences in total, but the number of terminals allowed for multiplexing is 4, that is, a maximum of 4 OCC sequences are multiplexed, then every 2 indicator values ​​correspond to the same OCC sequence.

[0084] Optionally, in an embodiment of the present application, when each set of indicator values ​​corresponds to one OCC information, different sets of indicator values ​​correspond to different OCC information.

[0085] Exemplarily, when each set of indication values ​​corresponds to an OCC information, when the indicated value value belongs to the first value value set (for example, 0 to 3), it corresponds to an OCC sequence with a length of 4; when the indicated value value belongs to the second value value set (for example, 4-11), it corresponds to an OCC sequence with a length of 8.

[0086] Optionally, in an embodiment of the present application, the above-mentioned TDRA information or SLIV information includes a default time domain resource allocation (default A) mode of the first signal; wherein, in the default time domain resource allocation mode, each TDRA information or each SLIV information corresponds to at least one OCC information.

[0087] Optionally, in an embodiment of the present application, multiple TDRA information or multiple SLIV information corresponds to the same OCC information.

[0088] Optionally, in an embodiment of the present application, the above-mentioned TDRA information or SLIV information is configured with the OCC information through the same high-level parameter, for example, the high-level parameter pusch-ConfigCommon or the high-level parameter pusch-Config.

[0089] Optionally, in an embodiment of the present application, the time domain resource and OCC information of the first signal determined through the TDRA information or the SLIV information meet a first condition; wherein the first condition includes at least one of the following:

[0090] The sum of the product of the number of occupied symbols of the first signal multiplied by the OCC sequence length and the starting symbol index of the first signal does not exceed the number of symbols corresponding to one time slot (for example, corresponding to 14 symbols). This can also be understood as the time domain symbol of the first signal based on the OCC being within one time slot.

[0091] The result of subtracting the number of occupied symbols of the DMRS from the number of occupied symbols of the first signal is an integer multiple of the OCC sequence length;

[0092] The number of occupied symbols of the first signal is an integer multiple of the OCC sequence length.

[0093] Exemplarily, the TDRA information or SLIV information is determined by the newly defined default A method, for example, a column of OCC length information is added to the original default A method, such as the OCC length column in Table 1 and Table 2 below:

[0094] Table 1: Default PUSCH time domain resource allocation A for normal CP

[0095] Table 2: Default PUSCH time domain resource allocation A for extended CP

[0096] When the higher-layer parameter pusch-ConfigCommon does not contain TDRA configuration

[0097] When the pusch-TimeDomainAllocationList or the higher-layer parameter pusch-Config does not include the TDRA configuration pusch-TimeDomainAllocationList, pusch-TimeDomainAllocationListDCI-0-1, or pusch-TimeDomainAllocationListDCI-0-2, the default A method is used to determine the TDRA information.

[0098] Optionally, in the embodiment of the present application, the DMRS port and the OCC information satisfy at least one of the following correspondences:

[0099] Each DMRS port corresponds to an OCC information;

[0100] Each DMRS port corresponds to multiple OCC information;

[0101] Multiple DMRS ports correspond to the same OCC information.

[0102] For example, assume that four terminals perform block-wise spreading multiplexing based on OCC information: the network-side device indicates DMRS ports 0, 1, 2, and 3 to the four terminals respectively, and the network-side device configuration or protocol defaults to the four DMRS ports corresponding to the four OCC sequences in Table 3 below. For example, DMRS port 0 corresponds to the first OCC sequence (n=0), DMRS port 1 corresponds to the second OCC sequence (n=1), DMRS port 2 corresponds to the third OCC sequence (n=2), and DMRS port 3 corresponds to the fourth OCC sequence (n=3). Then, the terminal can determine the OCC sequence used for PUSCH multiplexing through the indicated DMRS port.

[0103] Table 3

[0104] To adjust the OCC sequence used by the terminal, an offset can be introduced in the mapping between DMRS ports and OCC sequences. For example, offset = 1, that is, DMRS port 0 corresponds to the second OCC sequence (n = 1), DMRS port 1 corresponds to the third OCC sequence (n = 2), DMRS port 2 corresponds to the fourth OCC sequence (n = 3), and DMRS port 3 corresponds to the first OCC sequence (n = 0).

[0105] Optionally, in the embodiment of the present application, the CDM group corresponding to the port of the DMRS and the OCC information satisfy at least one of the following correspondences:

[0106] Each CDM group corresponds to one OCC information;

[0107] Each CDM group corresponds to multiple OCC information;

[0108] Multiple CDM groups correspond to the same OCC information.

[0109] Optionally, in the embodiment of the present application, the number of DMRS symbols (the number of DMRS leading symbols, the number of DMRS additional symbols, or the number of DMRS occupied symbols) and the OCC information satisfy at least one of the following corresponding relationships:

[0110] Each symbol number corresponds to an OCC information;

[0111] Each symbol number corresponds to multiple OCC information;

[0112] Multiple symbol numbers correspond to the same OCC information;

[0113] Each set of symbol numbers corresponds to an OCC information.

[0114] Exemplarily, different numbers of symbols correspond to different OCC information. For example, when the number of symbols = 1, it corresponds to an OCC sequence with a length of 4; for example, when the number of symbols = 2, it corresponds to an OCC sequence with a length of 8.

[0115] Optionally, in the embodiment of the present application, the scrambling code identifier of the DMRS and the OCC information satisfy at least one of the following correspondences:

[0116] Each scrambling code identifier corresponds to an OCC information;

[0117] Each scrambling code identifier corresponds to multiple OCC information;

[0118] Multiple scrambling code identifiers correspond to the same OCC information.

[0119] Optionally, in an embodiment of the present application, there is a corresponding relationship between the above-mentioned RU information and OCC information.

[0120] Optionally, in an embodiment of the present application, the above-mentioned correspondence is a default agreement of the protocol; or, the above-mentioned correspondence is configured by a network-side device. For example, a certain value is fixedly corresponding to a certain OCC information; or the correspondence between each value and OCC information is configured or adjusted through RRC signaling or MAC CE signaling. For another example, the correspondence between RU information and OCC information can also be a default agreement of the protocol or configured by a network-side device.

[0121] Optionally, in an embodiment of the present application, the above-mentioned OCC-related parameters may include at least one of the following: OCC sequence set, OCC sequence, OCC sequence index set, OCC sequence index, OCC sequence length set, OCC sequence length, and OCC enabling information.

[0122] Optionally, in the embodiment of the present application, the above OCC-related parameters are indicated by the first DCI. It can also be understood that the terminal determines the OCC-related parameters based on the first DCI.

[0123] Optionally, in an embodiment of the present application, the above-mentioned first DCI includes but is not limited to any one of the following: modulation and coding scheme (MCS) field, redundancy version (RV) field, frequency hopping flag field, antenna port (Antenna ports) field, hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process number field, and other DCI fields. Other DCI fields may be DCI fields other than the above-mentioned MCS field, RV field, frequency hopping flag field, antenna port field, and HARQ process number field.

[0124] It should be noted that the above-mentioned other DCI domains can be understood as a new DCI domain, such as a DCI domain used to specifically indicate OCC information. When the first domain (that is, the DCI domain other than other DCI domains in the above-mentioned first DCI) is default or occupies 0 bits, the first domain can be reinterpreted as being used to indicate OCC information, which is equivalent to introducing a new DCI domain.

[0125] For example, for DCI formats 0_1 and 0_2, a new DCI field can be introduced to indicate OCC information. For example, the new DCI field can be used to indicate at least one of the following:

[0126] OCC enable information: 1 bit, used to indicate whether OCC transmission is enabled;

[0127] OCC length: 1 bit, used to indicate the OCC length. For example, a value of 0 indicates an OCC length of 2, and a value of 1 indicates an OCC length of 1. Other numbers of bits are also possible, such as directly indicating 2 using 2 bits of '01', or 4 using 2 bits of '11';

[0128] OCC sequence index: 2 bits, used to indicate the index in the OCC sequence set to determine the OCC sequence. For example, '00' indicates the use of the first sequence in the following OCC sequence set [+1+1+1+1], and '01' indicates the use of the first sequence in the following OCC sequence set [+1-j-1+j]. Other values ​​or meanings are possible; the above is just an example.

[0129] Exemplarily, at least some bits in the MCS field in the DCI are used to indicate the OCC sequence index. For example, the highest 2 bits are used to indicate the OCC sequence index: '00' indicates OCC sequence index 0; '01' indicates OCC sequence index 1; '10' indicates OCC sequence index 2; and '11' indicates OCC sequence index 3.

[0130] Exemplarily, at least some bits in the RV field in the DCI are used to indicate the OCC sequence index. For example, 2 bits in the RV field are used to indicate the OCC length, where '00' indicates an OCC length of 1; '01' indicates an OCC length of 2; '10' indicates an OCC length of 4; and '11' indicates an OCC length of 8.

[0131] For example, the frequency hopping indication field in the DCI is used to indicate OCC enable information. For example, '0' indicates that OCC transmission is enabled, and '1' indicates that OCC transmission is disabled. Alternatively, '0' indicates that OCC transmission is disabled, and '1' indicates that OCC transmission is enabled.

[0132] Optionally, in the embodiment of the present application, the terminal does not expect OCC transmission and uplink frequency hopping transmission to be enabled or configured at the same time.

[0133] Optionally, in the embodiment of the present application, the above OCC-related parameters are indicated by high-level parameters. For example:

[0134] Another example:

[0135] Optionally, in an embodiment of the present application, when the above-mentioned OCC-related parameters include OCC enabling information, the OCC enabling information can be determined by whether the high-level parameter configuration provides OCC information configuration. For example, if the high-level parameters provide the above-mentioned OCC-config, it is considered that OCC transmission is enabled; if the high-level parameters do not provide the above-mentioned OCC-config, it is considered that OCC transmission is not enabled.

[0136] Optionally, in an embodiment of the present application, the above OCC-related parameters are jointly indicated by the first DCI and higher-layer parameters;

[0137] The high-level parameter configuration is a first set, and the first DCI indicates an element in the first set. The first set includes any one of the following:

[0138] Items in aggregate form in OCC information;

[0139] Multiple non-aggregate items in OCC information;

[0140] Multiple sets of OCC information.

[0141] It should be noted that an element in the first set can be understood as an item in the first set, or a group of OCC information. If the first set of the above-mentioned high-layer parameter configuration contains only one value or a group of configurations, the first DCI indication is not required.

[0142] Optionally, in an embodiment of the present application, the items in the above-mentioned set form may include at least one of the following: an OCC sequence set, an OCC sequence length set, and an OCC sequence index set.

[0143] Optionally, in an embodiment of the present application, the above-mentioned non-aggregate item may include at least one of the following: OCC sequence, OCC sequence index, OCC sequence length, and OCC enabling information.

[0144] For example, a higher-layer parameter configuration specifies a first set (e.g., an OCC sequence length set) of {2, 4, 8}, and uses at least some bits in the MCS field in the DCI to indicate an index in the first set. For example, '00' indicates that the OCC length is the first value in the first set, 2; '01' indicates that the OCC length is the fourth value in the first set, 4; '10' indicates that the OCC length is the third value in the first set, 8; and '11' indicates a reserved value.

[0145] For example, the high-level parameter configuration has a first set, which includes two groups of OCC parameter configurations, as shown below:

[0146] The first group of OCC parameter configuration:

[0147] The second set of OCC parameter configuration:

[0148] The frequency hopping indicator field may be used to indicate an index in the first set. For example, '0' indicates that the first information is the first group of parameter configurations in the first set, and '1' indicates that the first information is the second group of parameter configurations in the first set.

[0149] Exemplarily, a higher-layer parameter configures a first set (e.g., an OCC sequence set) including OCC sequences [+1+1+1+1], [+1-j-1+j], [+1-1+1-1], and [+1+j-1-j]. At least some bits in the RV field may be used to indicate the OCC index. For example, '00' indicates that the determined OCC sequence is the first sequence [+1+1+1+1] in the first set, and '01' indicates that the determined OCC sequence is the second sequence [+1-j-1+j] in the first set.

[0150] Optionally, in the embodiment of the present application, the indication method of the first DCI includes any one of the following:

[0151] Indicating by a first bit number, the first bit number being related to the number of elements in the first set;

[0152] The indication is performed through a second bit number, where the second bit number is related to the maximum number of elements in the first set.

[0153] It should be noted that the number of elements in the first set can be understood as the actual number of elements contained in the first set. Assuming that the first set has only two elements, only 1 bit of DCI is required, such as '0' for the first element and '1' for the second element.

[0154] The maximum number of elements in the first set can be understood as the maximum number of elements supported by the first set. At this time, even if there are only 2 elements in the first set, if the maximum number of elements supported by the first set is 4, then DCI 2 bits are required to indicate it.
