In some embodiments, the network device may configure the downlink sub-band for the terminal in a second type of time slot, wherein the second type of time slot includes at least one of: uplink time slot and flexible time slot.

The frequency domain resource corresponding to the uplink time slot is an uplink frequency domain resource, and a downlink sub-band is configured for the terminal in the uplink time slot, and the frequency domain resource corresponding to the downlink sub-band in the frequency domain resource of the uplink time slot can be used for downlink communication, so that the network device can perform downlink communication in the downlink sub-band corresponding to the uplink time slot and perform uplink communication in the frequency domain resource outside the downlink sub-band, thereby realizing full duplex communication.

The frequency domain resources corresponding to the flexible time slots can be configured or scheduled as uplink frequency domain resources, downlink sub-bands are configured for the terminal in the flexible time slots, and the frequency domain resources corresponding to the downlink sub-bands in the frequency domain resources of the flexible time slots can be used for downlink communication, so that the network equipment can perform downlink communication in the downlink sub-bands corresponding to the flexible time slots and perform uplink communication in the frequency domain resources outside the downlink sub-bands, thereby realizing full duplex communication.

In some embodiments, the communication that the terminal may engage in with the network device in the time domain unit includes at least one of: data communication, non-data communication (e.g., signaling communication).

In the case where a terminal performs data communication in time domain units (e.g., the terminal transmits a Transport Block (TB) to a network device or receives a Transport Block transmitted by the network device), in some scenarios, data communication may be performed in multiple time domain units, e.g., a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) may be repeatedly received (repeated) in multiple time domain units. For data communication in multiple time domain units, one modulation coding strategy (Modulation and Coding Scheme, MCS) may be configured.

However, when the plurality of time-domain units includes an SBFD time-domain unit and a non-SBFD time-domain unit (i.e., a time-domain unit not configured with a subband), since there is both uplink and downlink communication on the SBFD time-domain unit, and only uplink or downlink communication is present on the non-SBFD time-domain unit, interference on the SBFD time-domain unit may be relatively large with respect to interference on the non-SBFD time-domain unit. The interference may include, among other things, interference to the network device and/or interference to the terminal.

If the same modulation and coding strategy is adopted for communication on a plurality of time domain units, the modulation and coding strategy is difficult to be simultaneously and well applied to the SBFD time domain units and the non-SBFD time domain units, and the communication quality of the SBFD time domain units is easy to be influenced.

In a first aspect, embodiments of the present disclosure provide a modulation and coding strategy determination method. Fig. 3 is a schematic flow chart diagram illustrating a modulation coding strategy determination method according to an embodiment of the present disclosure. The modulation and coding strategy determination method shown in this embodiment may be performed by a terminal.

As shown in fig. 3, the modulation and coding strategy determining method may include the steps of:

in step S301, a modulation coding strategy for data communication over at least one of a plurality of time domain units is determined based on the first information, wherein the plurality of time domain units comprises a first type of time domain unit configured with subbands and a second type of time domain unit not configured with subbands.

In some embodiments, the first information includes at least one of: rules agreed by the protocol; signaling of the network device, e.g., radio resource control (Radio Resource Control, RRC) signaling.

In some embodiments, a terminal may communicate data with a network device in a plurality of time domain units, where the plurality of time domain units includes a first type of time domain unit (e.g., SBFD time domain unit) and a second type of time domain unit (e.g., non-SBFD time domain unit), the terminal may determine a modulation coding strategy for the data communication on at least one time domain unit based on the first information, where the modulation coding strategy for the data communication on the first type of time domain unit and the second type of time domain unit may be different.

In some embodiments, the data communication is not limited to the physical downlink shared channel in which the terminal receives repeated transmissions, but may also include other types of data communication, for example, the data communication includes at least one of:

a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) repeatedly transmitted on the plurality of time domain units;

a physical uplink shared channel (physical uplink shared channel) sent on the plurality of time domain units based on a Configuration Grant (CG) mode;

In some embodiments, the repeatedly transmitted physical uplink shared channel (PUSCH repetition) includes at least one of: PUSCH repetition Type A, PUSCH repetition Type B.

In some embodiments, the physical uplink shared channel transmitted based on the configuration grant includes at least one of: type-1CG PUSCH, type-2CG PUSCH.

In some embodiments, the physical downlink shared channel received based on the triggering manner includes, but is not limited to, a Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) physical downlink shared channel, wherein the Semi-persistent scheduling physical downlink shared channel may be triggered by downlink control information (Downlink Control Information, DCI).

In some embodiments, the time domain unit comprises at least one of: a frame, a subframe, a slot, a symbol (symbol), wherein the symbol may be an OFDM (Orthogonal Frequency Division Multiplexing ) symbol, for example.

As shown in fig. 4, for example, the network device configures an uplink subband in a downlink slot as a terminal, for example, a frequency domain resource corresponding to the downlink slot includes at least one BandWidth Part (BWP).

As in case a of fig. 4, the network device may perform uplink communication with the terminal in an uplink sub-band in a downlink timeslot, or may perform downlink communication with the terminal in a frequency domain resource other than the uplink sub-band, and the uplink resource for uplink communication and the downlink resource for downlink communication may not overlap. The terminal performing the uplink communication and the terminal performing the downlink communication in the same slot may be different terminals.

As in case b of fig. 4, the network device may perform uplink communication with the terminal in an uplink sub-band in a downlink timeslot, or may perform downlink communication with the terminal in the uplink sub-band, and the uplink resource for uplink communication and the downlink resource for downlink communication may completely overlap.

As in case c of fig. 4, the network device may perform uplink communication with the terminal in an uplink sub-band in a downlink timeslot, or may perform downlink communication with the terminal in an uplink sub-band and a frequency domain resource other than the uplink sub-band, where an uplink resource for uplink communication and a downlink resource for downlink communication may partially overlap.

In one embodiment, the SBFD time slots may correspond to a time division duplex (Time Division Duplexing, TDD) frequency band in which the network device may configure the uplink and downlink bandwidth portions for the terminal. As shown in fig. 5, the network device may align the center frequency point of the uplink bandwidth portion with the center frequency point of the downlink bandwidth portion, and then configure the uplink bandwidth portion and the downlink bandwidth portion after the center frequency point is aligned to the terminal.

The frequency domain ranges of the downlink bandwidth portion and the uplink bandwidth portion may be the same or different, which is not a limitation of the present disclosure.

For example, a time slot structure configured by the network device for the terminal through time division duplex uplink and downlink configuration (TDD UL-DL configuration) is DDDDDDSUUU, where D represents a downlink time slot, U represents an uplink time slot, S represents a flexible time slot, that is, among 10 time slots, slot #0 to slot #5 are downlink time slots, slot #6 is a flexible time slot, and slot #7 to slot #9 are uplink time slots.

The frequency domain resource corresponding to the downlink time slot may include a downlink bandwidth portion, and the frequency domain resource corresponding to the uplink time slot may include an uplink bandwidth portion.

In one embodiment, the operation of aligning the center frequency point of the upstream bandwidth portion and the center frequency point of the downstream bandwidth portion may be applicable to a scenario based on asymmetric spectrum (unpaired spectrum) communication, or may be applicable to a scenario based on symmetric spectrum (symmetric spectrum) communication.

In some embodiments, an association relationship between an index (index) and a modulation coding policy may be stored in the terminal, where the association relationship may be, for example, a table of relationships between the modulation coding policy and the index.

The network device may send first indication information to the terminal, where the first indication information may include a first index. The terminal may determine a first modulation coding strategy corresponding to the first index in the association relationship, and may determine a second coding strategy based on the first index and the first offset according to the indication of the first information. And further, data communication can be performed on the first type of time domain unit according to one of the first modulation coding strategy and the second modulation coding strategy, and data communication can be performed on the second type of time domain unit according to the other of the first modulation coding strategy and the second modulation coding strategy.

According to the method, different modulation and coding strategies can be determined for the first time domain unit and the second time domain unit, so that the data communication on the first time domain unit and the second time domain unit can be conveniently applied by adopting the different modulation and coding strategies, the influence of interference on the data communication in the first time domain unit can be relieved, and the communication quality of the data communication in the first time domain unit is further guaranteed.

In the case where the first information is transmitted from the network device to the terminal, the first instruction information may be included in the first information, or the first instruction information may be included in addition to the first information.

In some embodiments, the first offset is determined based on a protocol convention or indicated by the network device. For example, the first offset may be a positive integer or a negative integer.

For example, in the case where the network device indicates the first offset, the network device may carry the first offset and the first index through the first indication information. Alternatively, the network device may indicate the first offset to the terminal in advance before sending the first indication information, for example, the network device may send the first offset or an index of the first offset to the terminal through RRC signaling (may also be referred to as an RRC message) before the first indication information.

For example, in the case where the first offset is determined based on a protocol convention, the network device may not need to indicate the first offset to the terminal, e.g., the first indication information may carry only the first index and not the first offset. The terminal may determine the first offset according to a protocol convention.

In addition, for example, when the first offset is determined based on the protocol convention, the terminal may determine a plurality of first offsets based on the protocol convention, and may determine an association relationship between the first offset and the first index based on the protocol convention, and further the terminal may determine the first offset corresponding to the first index indicated by the network device according to the association relationship between the first offset and the first index. Accordingly, the first offset amount is flexibly determined.

In some embodiments, the determining a modulation coding strategy for data communication over at least one of a plurality of time domain units based on the first information comprises:

determining that the modulation coding strategy of the data communication on the first type of time domain unit is a first modulation coding strategy corresponding to the first index, and determining that the modulation coding strategy of the data communication on the second type of time domain unit is a second modulation coding strategy corresponding to a second index, wherein the second index is determined according to the first index and the first offset; or,

And determining that the modulation coding strategy of the data communication on the second type of time domain unit is a first modulation coding strategy corresponding to the first index, and determining that the modulation coding strategy of the data communication on the first type of time domain unit is a second modulation coding strategy corresponding to the second index, wherein the second index is determined according to the first index and the first offset.

In some embodiments, the network device may send first indication information to the terminal, where the first indication information may include a first index, and since one index corresponds to one modulation coding strategy, to determine the first modulation coding strategy and the second modulation coding strategy, the terminal may determine the second index according to the first index and the first offset, so that the first index and the second index may respectively correspond to the modulation coding strategy, for example, the first index corresponds to the first modulation coding strategy, and the second index corresponds to the second modulation coding strategy.

The first index may be used as a reference index, and in order to determine the second modulation coding strategy, the terminal may add (or subtract) the first offset to the reference index to obtain the second index, so as to determine the modulation coding strategy corresponding to the second index as the second modulation coding strategy.

When the terminal determines that the modulation coding strategy of the data communication on the first type time domain unit is the first modulation coding strategy corresponding to the first index, the second index can be determined according to the first index and the first offset, and the second modulation coding strategy corresponding to the second index is determined, then the second modulation coding strategy can be used as the modulation coding strategy of the data communication on the second type time domain unit.

When the terminal determines that the modulation coding strategy of the data communication on the second type time domain unit is the first modulation coding strategy corresponding to the first index, the second index can be determined according to the first index and the first offset, and the second modulation coding strategy corresponding to the second index is determined, then the second modulation coding strategy can be used as the modulation coding strategy of the data communication on the first type time domain unit.

In some embodiments, the modulation coding strategy determination method further comprises:

determining a modulation and coding strategy of data communication on the first type time domain unit as a first modulation and coding strategy corresponding to the first index according to the indication of the network equipment; or,

and determining the modulation coding strategy of the data communication on the second type time domain unit as a first modulation coding strategy corresponding to the first index according to the indication of the network equipment.

In some embodiments, the network device may send first indication information to the terminal, where the first indication information may include a first index, and since one index corresponds to one modulation coding strategy, the terminal needs to determine whether the first modulation coding strategy corresponding to the first index is a modulation coding strategy for data communication on the first type of time domain unit or a modulation coding strategy for data communication on the second type of time domain unit.

In this case, the network device may indicate whether the first modulation coding strategy corresponding to the first index is a modulation coding strategy for data communication on the first type of time domain unit or a modulation coding strategy for data communication on the second type of time domain unit.

For example, when the network device indicates that the first modulation and coding strategy corresponding to the first index is the modulation and coding strategy of data communication on the first type time domain unit, the terminal may determine, according to the indication of the network device, that the modulation and coding strategy of data communication on the first type time domain unit is the first modulation and coding strategy corresponding to the first index.

For example, when the network device indicates that the first modulation coding strategy corresponding to the first index is the modulation coding strategy of the data communication on the second type time domain unit, the terminal may determine, according to the indication of the network device, that the modulation coding strategy of the data communication on the second type time domain unit is the first modulation coding strategy corresponding to the first index.

determining a modulation and coding strategy of data communication on the first type time domain unit as a first modulation and coding strategy corresponding to the first index according to protocol convention; or,

and determining the modulation coding strategy of the data communication on the second type time domain unit as a first modulation coding strategy corresponding to the first index according to protocol convention.

In this case, the protocol convention may determine whether the first modulation and coding scheme corresponding to the first index is a modulation and coding scheme for data communication on the first type of time domain unit or a modulation and coding scheme for data communication on the second type of time domain unit.

For example, when the protocol convention determines that the first modulation coding strategy corresponding to the first index is the modulation coding strategy of the data communication on the first type time domain unit, the terminal may determine, according to the protocol convention, that the modulation coding strategy of the data communication on the first type time domain unit is the first modulation coding strategy corresponding to the first index.

For example, when the protocol convention determines that the first modulation coding strategy corresponding to the first index is the modulation coding strategy of the data communication on the second type time domain unit, the terminal may determine, according to the protocol convention, that the modulation coding strategy of the data communication on the second type time domain unit is the first modulation coding strategy corresponding to the first index.

Taking the example that the sub-band comprises an uplink sub-band, the time domain unit comprises a time slot, and the network equipment configures the uplink sub-band for the terminal in the downlink time slot. As shown in fig. 6, the slot structure determined by the terminal according to the TDD UL-DL configuration is ddddsuuu, one TDD UL-DL period (periodicity) includes 10 slots, slot #0 to slot #9, and the network device configures uplink subbands in slot #0 to slot # 3.

As shown in fig. 7, for example, data communication by the terminal over a plurality of slots includes PUSCH repetition, PUSCH of 4 times of repetition transmission of PUSCH is located in slot #8 and slot #9 in TDD UL-DL period #1, and slot #0 and slot #1 in TDD UL-DL period # 2.

Since uplink subbands are configured on slot #0 and slot #1, the network device may not only receive PUSCH repetition on the uplink subbands, but also perform downlink communication on frequency domain resources other than the uplink subbands on slot #0 and slot #1 of period #2, for example, the downlink communication may cause interference to a process of receiving PUSCH repetition. In contrast, only PUSCH is received in slot #8 and slot #9 of period #1, and no downlink communication is performed, so that there is no interference of the downlink communication to the PUSCH reception process. It can be seen that the interference on slot #0 and slot #1 of period #2 is stronger than the interference on slot #8 and slot #9 of period # 1.

If the modulation and coding strategy is determined by considering only the interference conditions on slot #8 and slot #9 in period #1 and is applied to slot #0 and slot #1 in period #2, because the interference on slot #0 and slot #1 in period #2 is relatively strong, when the modulation and coding strategy is adopted, the interference on slot #0 and slot #1 in period #2 is difficult to be relieved, and the communication quality of the network device for receiving PUSCH repetition on slot #0 and slot #1 in period #2 is easy to be affected.

In an embodiment of the disclosure, the terminal may determine the first index, and further the terminal may determine the second index according to the first index and the first offset. For example, the terminal determines, according to an indication of the network device or a protocol convention, that the first modulation and coding strategy corresponding to the first index is a modulation and coding strategy of data communication on the first type time domain unit.

Taking the first index #1 as 13 and the first offset as 2 as an example, the terminal may determine the second index # 2=index # 1+offset=15. Further, in the table of the relationship between the index and the modulation and coding scheme, it may be determined that the modulation and coding scheme corresponding to the index 13 (for example, the modulation and coding scheme level is 13) is the modulation and coding scheme for transmitting PUSCH repetition on the slot #0 and the slot #1 in the period #2, and that the modulation and coding scheme corresponding to the index 15 (for example, the modulation and coding scheme level is 15) is the modulation and coding scheme for transmitting PUSCH repetition on the slot #8 and the slot #9 in the period # 1.

Because the modulation and coding strategy corresponding to the index 13 is better in favor of guaranteeing the communication quality of data communication under the condition of relatively strong interference compared with the modulation and coding strategy corresponding to the index 15, the PUSCH repetition communication is carried out on the slot #0 and the slot #1 in the period #2 with strong interference by adopting the modulation and coding strategy corresponding to the index 13, which is beneficial to guaranteeing good communication quality.

As shown in fig. 8, for example, data communication performed by the terminal on a plurality of slots includes CG PUSCH (e.g., type-1CG PUSCH), and the transmission period of CG PUSCH is 5 slots. Three CG PUSCH transmissions are shown in fig. 8, slot #8 in TDD UL-DL period #1, and slot #3 and slot #8 in TDD UL-DL period #2, respectively.

Since the uplink sub-band is configured on slot #3, the network device not only can receive CG PUSCH on the uplink sub-band, but also can perform downlink communication on frequency domain resources outside the uplink sub-band on slot #3 of period #2, for example, the downlink communication can cause interference to the process of receiving CG PUSCH. In contrast, only PUSCH is received in slot #8 of period #1 and period #2, and no downlink communication is performed, so that there is no interference of downlink communication to the CG PUSCH reception process. It can be seen that the interference on slot #3 of period #2 is stronger than the interference on slot #8 of periods #1 and # 2.

If the modulation and coding scheme is determined considering only the interference situation on slot #8 in period #1 and period #2 and applied to slot #3 in period #2, since the interference on slot #3 in period #2 is relatively strong, it is difficult to alleviate the interference on slot #3 in period #2 when the modulation and coding scheme is adopted, and the communication quality of receiving CG PUSCH on slot #3 in period #2 is easily affected.

Taking the first index #1 as 13 and the first offset as 2 as an example, the terminal may determine the second index # 2=index # 1+offset=15. Further, in the table of the relationship between the index and the modulation and coding scheme, it may be determined that the modulation and coding scheme corresponding to the index 13 (for example, the modulation and coding scheme level is 13) is the modulation and coding scheme for transmitting CG PUSCH on slot #3 in period #2, and that the modulation and coding scheme corresponding to the index 15 (for example, the modulation and coding scheme level is 15) is the modulation and coding scheme for transmitting CG PUSCH on slot #8 in period #1 and period # 2.

Because the modulation and coding strategy corresponding to the index 13 is better in favor of guaranteeing the communication quality of data communication under the condition of relatively strong interference compared with the modulation and coding strategy corresponding to the index 15, CG PUSCH communication is carried out on slot #3 in a period #2 with strong interference by adopting the modulation and coding strategy corresponding to the index 13, and good communication quality is guaranteed.

In some embodiments, the first index may be indicated by the network device, but the first offset is agreed upon, and the first modulation and coding strategy corresponding to the first index is a modulation and coding strategy for data communication in the first type of time domain unit, or a modulation and coding strategy for data communication in the second type of time domain unit, which is also agreed upon by the protocol.

For example, the terminal determines, according to the protocol convention, that the first modulation coding strategy corresponding to the first index is a modulation coding strategy of data communication on the second type of time domain unit, and the first offset is-6. When the terminal receives the information sent by the network device, it determines that the first index #1 is binary 10000, that is, 16 decimal, and may determine that the second index # 2=index # 1+offse=10. Further, it may be determined that the modulation and coding strategy corresponding to the index 16 is a modulation and coding strategy for data communication on the second type of time domain unit (non-SBFD slot), and the modulation and coding strategy corresponding to the index 10 is a modulation and coding strategy for data communication on the first type of time domain unit (SBFD slot).

In some embodiments, the first information is used to instruct the terminal to determine a modulation coding strategy for data communication on at least one time domain unit of the plurality of time domain units according to a first index corresponding to the modulation coding strategy indicated by the network device and a plurality of modulation coding strategy tables (MCS tables).

For example, the plurality of modulation coding policy tables may be protocol-agreed, or may be pre-configured to the terminal by the network device (e.g., before indicating the first index), and the modulation coding policy tables may characterize an association between the modulation coding policies and the index. In the multiple modulation and coding strategy tables, each modulation and coding strategy table may be different, that is, the association relationship between the modulation and coding strategies and the indexes may be different, and then the terminal may determine different modulation and coding strategies in each modulation and coding strategy table according to one first index. Accordingly, the terminal can determine the modulation coding strategy of the data communication on at least one time domain unit and ensure that the modulation coding strategy of the data communication on the first type of time domain unit is different from that of the data communication on the second type of time domain unit.

In some embodiments, the modulation coding strategy table may be determined according to a protocol convention or may be indicated by the network device, e.g., the network device may indicate multiple modulation coding strategy tables to the terminal through RRC signaling (also referred to as RRC messages).

For example, two modulation and coding policy tables are stored in the terminal in advance, and the terminal may determine a first index #1 according to the first indication information. For example, the two modulation coding strategy tables are MCS table #1 and MCS table #2. The terminal may further determine the modulation and coding scheme corresponding to index #1 in MCS table #1, for example, MCS level 13, and determine the modulation and coding scheme corresponding to index #1 in MCS table #2, for example, MCS level 15.

For example, the association between two modulation coding strategy tables and the first type of time domain unit and the second type of time domain unit includes: MCS table #1 is associated with a first type of time domain unit and MCS table #2 is associated with a second type of time domain unit. The modulation and coding scheme determined by the terminal in MCS table #1 according to the first index may be used as a modulation and coding scheme used for data communication in the first type time domain unit, and the modulation and coding scheme determined by the terminal in MCS table #2 according to the first index may be used as a modulation and coding scheme used for data communication in the second type time domain unit.

The above embodiments mainly exemplarily describe the case where the terminal determines one first index from the first information. The case where the terminal determines a plurality of first indexes from the first information is exemplarily described below by several embodiments.

The network device may indicate a plurality of first indexes to the terminal through the first indication information, where one first index may correspond to one modulation coding strategy, and then the terminal may determine the plurality of modulation coding strategies according to the plurality of first indexes, and further may determine, among the plurality of modulation coding strategies, a modulation coding strategy used for data communication in a first type of time domain unit, and a modulation coding strategy used for data communication in a second type of time domain unit, so as to determine a modulation coding strategy for data communication on at least one time domain unit.

In some embodiments, the plurality of first indexes are two first indexes, wherein one first index corresponds to a modulation coding strategy for data communication on the first type of time domain unit, and the other first index corresponds to a modulation coding strategy for data communication on the second type of time domain unit.

For example, the data communication includes PUSCH repetition, and the network device may carry two modulation coding policy indication information (MCS indication), for example, the first indexes of the two modulation coding policies, i.e., index #1 and index #2, respectively, in an uplink grant (UL grant) for scheduling PUSCH.

The terminal can determine the modulation coding strategy mcs#1 corresponding to the index#1 and determine the modulation coding strategy mcs#2 corresponding to the index#2, and since the mcs#1 and the mcs#2 can be different, the terminal can determine the modulation coding strategy of the data communication on the first type time domain unit and the second type time domain unit according to the modulation coding strategy, and ensure that the modulation coding strategy of the data communication on the first type time domain unit and the second type time domain unit is different.

For example, the association of the two first indexes with the first type of time domain unit and the second type of time domain unit may include at least one of: respectively associating a first type time domain unit and a second type time domain unit according to the indexes from small to large; and respectively associating the first type time domain unit and the second type time domain unit according to the index from large to small.

Taking the example of respectively associating the first type time domain unit and the second type time domain unit from small to large according to indexes, index#1 can be associated with the first type time domain unit, and then modulation coding strategy MCS#1 corresponding to index#1 can be used as modulation coding strategy for carrying out data communication in the first type time domain unit; index #2 may be associated with a second type of time domain unit, and then the modulation and coding scheme MCS #2 corresponding to index #2 may be used as a modulation and coding scheme for data communication in the second type of time domain unit.

It should be noted that, the modulation and coding strategy used for data communication on the first type time domain unit determined by the terminal and the modulation and coding strategy used for data communication on the first type time domain unit determined by the network device are the same, so that the terminal and the network device can use the same modulation and coding strategy for data communication on the first type time domain unit. The modulation and coding strategy used by the terminal for data communication on the second type of time domain unit is the same as the modulation and coding strategy used by the network device for data communication on the second type of time domain unit, and accordingly, the same modulation and coding strategy can be adopted by the terminal and the network device for data communication on the second type of time domain unit.

The manner in which the network device determines the modulation and coding scheme for data communication over at least one of the plurality of time-domain units may correspond to the manner in which the terminal determines the modulation and coding scheme for data communication over at least one of the plurality of time-domain units. For example, the terminal determines a modulation and coding strategy used for data communication on the first type of time domain unit and a modulation and coding strategy used for data communication on the second type of time domain unit according to the first index and the first offset indicated by the network device, and the network device may also determine a modulation and coding strategy used for data communication on the first type of time domain unit and a modulation and coding strategy used for data communication on the second type of time domain unit according to the first index and the first offset indicated to the terminal; for example, the terminal may determine, according to the plurality of first indexes indicated by the network device, a modulation coding scheme used for data communication on the first type of time domain unit and a modulation coding scheme used for data communication on the second type of time domain unit, and the network device may also determine, according to the plurality of first indexes and the first offset indicated to the terminal, a modulation coding scheme used for data communication on the first type of time domain unit and a modulation coding scheme used for data communication on the second type of time domain unit. Reference may be made to the foregoing embodiments for details, and details are not repeated here.

In a second aspect, embodiments of the present disclosure provide a modulation coding strategy determination method. Fig. 9 is a schematic flow chart diagram illustrating a modulation coding strategy determination method according to an embodiment of the present disclosure. The modulation and coding strategy determination method shown in this embodiment may be performed by a network device.

As shown in fig. 9, the modulation coding strategy determination method may include the steps of:

in step S901, first information is sent to a terminal, where the first information is used to determine a modulation coding strategy for data communication on at least one of a plurality of time domain units, the plurality of time domain units including a first type of time domain unit configured with subbands and a second type of time domain unit not configured with subbands.

In some embodiments, the network device may send the first information to the terminal through RRC signaling (may also be referred to as an RRC message).

In some embodiments, where the terminal is in data communication with the network device in a plurality of time domain units, and the plurality of time domain units includes a first type of time domain unit (e.g., SBFD time domain unit) and a second type of time domain unit (e.g., non-SBFD time domain unit), the network device may send first information to the terminal so that the terminal may determine a modulation coding strategy for data communication on at least one time domain unit based on the first information, where the modulation coding strategies for data communication on the first type of time domain unit and the second type of time domain unit may be different.

repeatedly receiving physical downlink shared channels on a plurality of time domain units;

a Physical Uplink Shared Channel (PUSCH) repeatedly transmitted on a plurality of time domain units;

a physical uplink shared channel transmitted on a plurality of time domain units based on a Configuration Grant (CG) mode;

and the physical downlink shared channel is received on a plurality of time domain units based on a triggering mode.

In some embodiments, the physical downlink shared channel received based on the triggering manner includes, but is not limited to, a semi-persistent scheduling (SPS) physical downlink shared channel, wherein the semi-persistent scheduling physical downlink shared channel may be triggered by Downlink Control Information (DCI).

In some embodiments, the time domain unit comprises at least one of: a frame, a subframe, a slot, a symbol (symbol), wherein the symbol may be an OFDM symbol, for example.

In some embodiments, the first information is used to instruct the terminal to determine a first modulation coding strategy for data communication on the first type of time domain unit and a second modulation coding strategy for data communication on the second type of time domain unit according to a first offset and a first index corresponding to the one modulation coding strategy indicated by the network device.

In some embodiments, the method further comprises:

the method comprises the steps that an indication terminal determines a modulation coding strategy of data communication on a first type of time domain unit to be a first modulation coding strategy corresponding to a first index; or,

the terminal is instructed to determine a modulation and coding strategy for data communication on the second type of time domain unit as a first modulation and coding strategy corresponding to the first index.

The network device may indicate whether the first modulation and coding scheme corresponding to the first index is a modulation and coding scheme for data communication on the first type of time domain unit or a modulation and coding scheme for data communication on the second type of time domain unit.

Since uplink subbands are configured on slot #0 and slot #1, the network device may not only receive PUSCH repetition on the uplink subbands, but also perform downlink communication on frequency domain resources other than the uplink subbands on slot #0 and slot #1 of period #2, for example, the downlink communication may cause interference to a process of receiving PUSCH repetition. In contrast, only PUSCH is received in slot #8 and slot #9 of period #1, and no downlink communication is performed, so that there is no interference of the downlink communication to the PUSCH reception process. It can be seen that the interference on slot #0 and slot #1 of period #2 is stronger than the interference on slot #8 and slot #9 of period #1.

Correspondingly, the network device may also determine the modulation and coding strategy according to the above manner, so as to determine the modulation and coding strategy corresponding to the index 13 (for example, the modulation and coding strategy level is 13) as the modulation and coding strategy for receiving PUSCH repetition on the slot #0 and the slot #1 in the period #2, and determine the modulation and coding strategy corresponding to the index 15 (for example, the modulation and coding strategy level is 15) as the modulation and coding strategy for receiving PUSCH repetition on the slot #8 and the slot #9 in the period # 1.

As shown in fig. 8, for example, data communication by the terminal over a plurality of slots includes CG PUSCH having a transmission cycle of 5 slots. Three CG PUSCH transmissions are shown in fig. 8, slot #8 in TDD UL-DL period #1, and slot #3 and slot #8 in TDD UL-DL period #2, respectively.

If the modulation and coding strategy is determined by considering only the interference conditions on slot #8 in period #1 and period #2 and is applied to slot #3 in period #2, because the interference on slot #3 in period #2 is relatively strong, when the modulation and coding strategy is adopted, the interference on slot #3 in period #2 is difficult to be relieved, and the communication quality of the network device receiving CG PUSCH on slot #3 in period #2 is easily affected.

Correspondingly, the network device may also determine the modulation and coding scheme in the above manner, so as to determine the modulation and coding scheme corresponding to the index 13 (for example, the modulation and coding scheme level is 13) as the modulation and coding scheme for receiving the CG PUSCH on the slot #3 in the period #2, and determine the modulation and coding scheme corresponding to the index 15 (for example, the modulation and coding scheme level is 15) as the modulation and coding scheme for receiving the CG PUSCH on the slot #8 in the period #1 and the period # 2.

In some embodiments, the first information is used to instruct the terminal to determine a modulation coding strategy for data communication on at least one of the plurality of time domain units according to a first index corresponding to the one modulation coding strategy indicated by the network device and the plurality of modulation coding strategy tables.

For example, the plurality of modulation coding policy tables may be protocol-agreed, or may be pre-configured to the terminal by the network device (e.g., before indicating the first index), and the modulation coding policy tables may characterize an association between the modulation coding policies and the index. The network device may determine the different modulation coding strategies in each modulation coding strategy table according to a first index by indicating the first index to the terminal. Accordingly, the terminal can determine the modulation coding strategy of the data communication on at least one time domain unit and ensure that the modulation coding strategy of the data communication on the first type of time domain unit is different from that of the data communication on the second type of time domain unit.

In some embodiments, the plurality of modulation coding policy tables is two modulation coding policy tables, wherein a first index corresponds to a modulation coding policy in one modulation coding policy table for data communication over a first type of time domain unit and a first index corresponds to a modulation coding policy in another modulation coding policy table for data communication over a second type of time domain unit.

For example, two modulation and coding policy tables are stored in the terminal in advance, and the network device may indicate a first index #1 to the terminal through the first indication information. For example, the two modulation coding strategy tables are MCS table #1 and MCS table #2. The terminal may further determine the modulation and coding scheme corresponding to index #1 in MCS table #1, for example, MCS level 13, and determine the modulation and coding scheme corresponding to index #1 in MCS table #2, for example, MCS level 15.
