wherein the first repeated transmission includes at least one of physical uplink shared channel PUSCH repeated transmission and physical uplink control channel PUCCH repeated transmission; the configured frequency hopping includes at least one of inter-time unit frequency hopping (inter-slot FH) and inter-repetition frequency hopping (inter-repetition FH); the time unit comprises X1 time slots or X2 sub time slots, X1 is more than or equal to 1, X2 is more than or equal to 1, and the frequency hopping between repeated transmissions means that frequency hopping is carried out for every X3 repeated transmissions, and X3 is more than or equal to 1; the PUSCH repetition transmission types include a PUSCH repetition transmission type A (PUSCH repetition Type A) and a PUSCH repetition transmission type B (PUSCH repetition Type B), and the PUCCH repetition transmission types include Slot-based PUCCH repetition transmission (Slot-based PUCCH repetition) and Sub-Slot-based PUCCH repetition transmission (Sub-Slot based PUCCH repetition).

the frequency hopping is abandoned, namely, the uplink transmission is executed, but the uplink transmission does not execute the frequency hopping;

the resources of the second hop are not expected to overlap with other resources, which are resources of the network configuration other than the resources of the second hop, i.e. the network ensures that the resources of the second hop do not collide with other resources.

Alternatively, for PUSCH using a discrete fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM) waveform, the first value is equal to 2;

for PUSCH using a cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) waveform, the first value is equal to 1;

for PUCCH, the first value is equal to 2 if the PUCCH format is 1,3 or 4, and is equal to 1 if the PUCCH format is 0 or 2.

The terminal is a reduced capability terminal (Reduced Capability, redCap device/UE, also referred to as reduced capability terminal).

According to the frequency hopping processing method, for PUSCH repeated transmission and/or PUCCH repeated transmission, under the condition that frequency hopping is configured, according to the first condition, a first operation is performed, such as discarding transmission of first frequency hopping and second frequency hopping, discarding transmission of second frequency hopping, discarding frequency hopping or not expecting that resources of second frequency hopping overlap with other resources, so that influence of radio frequency readjustment time on frequency hopping effective information is reduced, and further frequency hopping gain is guaranteed.

In the embodiment of the application, the RedCAP is setWhen uplink transmission is performed on a wide bandwidth part (BWP) such as a bandwidth part (maximum operating bandwidth) of more than 20MHz (maximum operating bandwidth of a terminal), the length of the radio frequency retune time required by uplink transmission at different bandwidths is defined as N _regap Symbols N _regap ≥1。

The radio frequency retune time is related to at least one of:

the capability drops the capability of the terminal;

and transmitting corresponding transmission content in an uplink mode.

As a first alternative implementation manner, in a case where the first retransmission is PUSCH retransmission type a or PUCCH retransmission and the configured frequency hopping is inter-time unit frequency hopping, before the terminal performs the first operation, the method further includes:

The terminal executes a second operation;

the second operation includes at least one of:

determining the position occupied by the radio frequency retuning time in the first hop and/or the second hop under the condition that the time interval between the first hop and the second hop allocated by the network is smaller than the radio frequency retuning time;

wherein the first operation is different from the second operation.

As shown in fig. 3, 4 and 5, for PUSCH retransmission type a or PUCCH retransmission, when the number of retransmission times k=2, the radio frequency retune time is guaranteed by the network (i.e., does not occupy the valid symbols of data or signal transmission).

Further alternatively, in the case where X1 > 1, or X2 > 1, PUSCH or PUCCH on each of the time units can be subjected to joint channel estimation.

Further alternatively, in the case where X1 > 1, or X2 > 1,

If the number of time cells starts from 0, (S) mod 2=0, indicating that the transmission on the time cells numbered even is the first hop, (S) mod 2=1, indicating that the transmission on the time cells numbered odd is the second hop, and S indicates the number of time cells.

In an embodiment of the present application, PUSCH or PUCCH on every X1 slots (or X2 sub-slots) can perform joint channel estimation, and every X1 slots (or X2 sub-slots) is called Slot band (Slot Bundle), which is the time unit described above. When (S) mod 2=0, it indicates that the uplink data, control information, or signal transmitted on the even numbered slot bands have the same frequency domain position, and the start position is configured or indicated by the network, which is called a first hop (first hop). (S) mod2 = 1, representing uplink data, control information or signals transmitted on the odd numbered slot bands, whose frequency domain locations are identical, the starting location being configured or indicated by the network, called the second hop (second hop)

Optionally, determining the position occupied by the radio frequency retuning time in the first hop and/or the second hop includes:

determining the last N of the first hop occupied by the RF retune time _regap A number of symbols;

alternatively, determining that the RF retune time occupies the beginning N of the second hop _regap A number of symbols;

or determining that the radio frequency retune time occupies the last M1 symbols of the first hop and the first M2 symbols of the second hop respectively;

or determining that the radio frequency retune time occupies the last M2 symbols of the first hop and the first M1 symbols of the second hop respectively;

wherein m1=floor/ceil (N _regap /2)，M2＝N _regap –M1，N _regap The number of symbols corresponding to the radio frequency retune time is represented, and M1 represents the last M1 symbols of the first hop occupied by the radio frequency retune time or represents the first M1 symbols of the second hop occupied by the radio frequency retune time.

As shown in fig. 6, 7, and 8, for PUSCH retransmission type a or PUCCH retransmission, N is when the number of retransmission times k=4 _regap The rf retune time occupies the effective symbols of data or signal transmission, and the time unit includes two slots, i.e. once every two slots, each small rectangle in fig. 6, 7 and 8 represents 2 OFDM symbols.

Further optionally, the symbol corresponding to the radio frequency retune time is contained at the beginning N of the second hop _regap In the case of the next symbol, the position of the first DMRS of the second hop is the nth _regap And a symbol.

In this case, optionally, in the case where the transmission length after the second hop excluding the radio frequency retune time is less than or equal to the first symbol interval, then the transmission of the extra DMRS (additional DMRS) is discarded in the second hop;

Wherein the first symbol interval is a symbol interval between the configured first DMRS and an additional DMRS.

Further alternatively, in the case that the symbol corresponding to the radio frequency retune time is included in the last M1 symbol of the first hop and the first M2 symbols of the second hop, the first DMRS of the second hop is located at the M2 th symbol.

In this case, optionally, in the case that the transmission length after the second hop excluding M2 symbols is less than or equal to the first symbol interval, transmitting an additional DMRS is discarded in the second hop;

Further optionally, at least one symbol corresponding to the radio frequency retuning time is included in the second hop, and the symbol corresponding to the radio frequency retuning time included in the second hop and at least one DMRS in the second hop do not overlap with each other, the position of the DMRS on the first symbol in the second hop remains unchanged, and the first symbol is a symbol in the second hop except for the symbol corresponding to the radio frequency retuning time.

As a second alternative implementation manner, in a case where the first retransmission is PUSCH retransmission type B or PUCCH retransmission (PUCCH transmission similar to PUSCH retransmission type B), and the configured hopping is inter-time unit hopping, before the terminal performs the first operation, the method further includes:

The terminal executes a third operation;

the third operation includes at least one of:

a first item: determining a symbol corresponding to the radio frequency retune time as an invalid symbol, and dividing nominal PUSCH repeated transmission or nominal PUCCH repeated transmission into a plurality of actual repeated transmissions according to the invalid symbol;

the second item: determining that a symbol corresponding to the radio frequency retune time is not an invalid symbol, and performing rate matching or punching at the symbol corresponding to the radio frequency retune time when actual transmission is performed;

third item: and determining that a symbol corresponding to the radio frequency retune time is not used as an effective symbol for data transmission, and delaying the transmission of the PUSCH or the PUSCH corresponding to the radio frequency retune time.

The above nominal PUSCH retransmission may be understood as a PUSCH retransmission configured or allocated by a network, and the nominal PUCCH retransmission may be understood as a PUSCH retransmission configured or allocated by a network.

Optionally, in this implementation, if X3 > 1, the PUSCH or PUCCH on every X3 repeated transmissions may be used for joint channel estimation if the configured frequency hopping is inter-repeated transmission frequency hopping.

Optionally, in this implementation, if X3 > 1 and the number of the retransmission groups starts from 0, then (N) mod 2=0 indicates that the transmission on the retransmission group with the number even is the first hop, (N) mod 2=1 indicates that the transmission on the retransmission group with the number odd is the second hop, N indicates the number of the retransmission group, and each X3 retransmission is one retransmission group.

Optionally, for the first item, in a case that the symbol corresponding to the radio frequency retune time is determined to be an invalid symbol, the symbol corresponding to the radio frequency retune time is determined by at least one of the following:

a radio resource control, RRC, configuration, as indicated by an invalid symbol type (invalidity symbol pattern) of the RRC configuration;

an indication of downlink control information DCI, such as an invalid symbol type indication (invalidity symbol indicator) indicated by the DCI.

By the method, the symbol corresponding to the radio frequency retune time can be flexibly indicated.

Further alternatively, the radio frequency retune time occupies the last N of the first hop _regap Symbols, or, occupy the beginning N of the second hop _regap A number of symbols, or the last M1 symbols occupying the first hop and the first M2 symbols occupying the second hop, respectively;

wherein m1=floor/ceil (N _regap /2)，M2＝N _regap –M1，N _regap Representing the radio frequency retune time, M1 represents the last M1 symbols where the radio frequency retune time occupies the first hop or represents the first M1 symbols where the radio frequency retune time occupies the second hop.

Here, the symbol corresponding to the radio frequency retune time is taken as an invalid symbol, and the position of the symbol corresponding to the radio frequency retune time is fixed.

Specifically, when the symbol corresponding to the radio frequency retune time is taken as an invalid symbol, the number of repeated transmissions k=4 is assumed, and the transmission length of one repeated transmission l= 5,N _regap As shown in fig. 9 and 10, the symbol corresponding to the radio frequency retune time may be indicated by RRC configuration or DCI, i.e. location flexible. As shown in fig. 11, 12 and 13, the positions of the symbols corresponding to the radio frequency retune time are fixed, i.e. fixed to the last two symbols of the first hop, the first two symbols of the second hop or the last symbol of the first hop and the first symbol of the second hop.

For the second item described above, as shown in fig. 14, for PUSCH retransmission type B, the number of retransmission times k=4, the transmission length of one retransmission l=5 symbols, N _regap =4, the symbols corresponding to the radio frequency retune time are at the last two symbols of the first hop and the first two symbols of the second hop,and taking the symbol corresponding to the radio frequency retune time as an invalid symbol, and performing rate matching or punching at the symbol corresponding to the radio frequency retune time when actual transmission is performed, wherein 'x' represents punching or rate matching. As can be seen from fig. 14, the third nominal retransmission (nominal repetition) is split into 2 actual retransmissions (actual repetition) encountering the slot boundary, and cannot be used to transmit data according to the protocol convention since the second actual retransmission in slot n+1 is 1 symbol in length.

For the third item described above, as shown in fig. 15, 16 and 17, for the repetition transmission like PUSCH repetition transmission type B, the repetition transmission number k=5, the transmission length l=5 symbols of one repetition transmission, N _regap The symbol corresponding to the radio frequency retune time is not counted as an effective symbol for data/signal transmission, and the transmission of the actual PUSCH affected is deferred. In fig. 17, the actual repetition of the third nominal repetition in the time slot n+1 has a length of 1 symbol, and no data is transmitted at this time, and the data is not transmitted as a valid symbol.

In addition, for the second and third items, fixing the RF-readjusting time to occupy the last N of the first hop _regap Symbols, or, occupy the beginning N of the second hop _regap Or the last M1 symbols of the first hop and the first M2 symbols of the second hop, respectively.

As a third alternative implementation manner, in a case where the configured frequency hopping is frequency hopping between repeated transmissions, before the terminal performs the first operation, the method further includes:

the terminal executes a fourth operation;

the fourth operation includes at least one of:

determining a symbol corresponding to the radio frequency retune time as an invalid symbol, and dividing nominal PUSCH repeated transmission or nominal PUCCH repeated transmission into a plurality of actual repeated transmissions according to the invalid symbol;

Determining that a symbol corresponding to the radio frequency retune time is not an invalid symbol, and performing rate matching or punching at the symbol corresponding to the radio frequency retune time when actual transmission is performed;

determining that a symbol corresponding to the radio frequency retune time is not used as an effective symbol for data transmission, and delaying the transmission of a PUSCH or a PUCCH corresponding to the radio frequency retune time;

in floor (N) _regap In case of/L) < X4, determining that the inter-repetition transmission frequency hopping of PUSCH repetition transmission type A is not supported, L representing a transmission length of repetition transmission groups each including X3 repetition transmissions, N _regap And X4 is a preset value, and represents the number of symbols corresponding to the radio frequency retune time.

Optionally, in this implementation manner, the symbol corresponding to the radio frequency retune time is determined by at least one of the following:

radio resource control, RRC, configuration;

indication of downlink control information DCI.

Optionally, the radio frequency retune time occupies the last N of the first hop _regap Symbols, or, occupy the beginning N of the second hop _regap A number of symbols, or the last M1 symbols occupying the first hop and the first M2 symbols occupying the second hop, respectively;

As shown in fig. 18, for the repetition transmission of PUSCH repetition transmission type B, the repetition transmission number k=5, the transmission length l=5 symbols of one repetition transmission, N _regap =2, the symbol corresponding to the radio frequency retune time is taken as an invalid symbol, and the nominal PUSCH retransmission is divided into a plurality of actual retransmission by the radio frequency retune time. As shown in fig. 19, the symbol corresponding to the radio frequency retune time is not an invalid symbol, and the actual PUSCH repeated transmission is punctured or rate matched at the symbol corresponding to the radio frequency retune time, where "x" indicates rate matching or puncturing. As shown in fig. 20, the symbol corresponding to the radio frequency retune time is not used as the effective symbol for data transmission, and the affected symbol is deferredAnd the PUSCH corresponding to the radio frequency retune time.

In addition, the method of the embodiment of the application may also be applied to the transmission of one Transport Block (TB) in a plurality of time slots, and the network configuration or the indication of the scenario of performing frequency hopping in a time slot may also be applied to the scenario that downlink transmission needs to maintain the single carrier characteristic and needs to obtain the frequency diversity gain.
