It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

Release 18 (Release 18, rel 18) SBFD communication problems have been introduced, and a base station configures UL subband on a DownLink (DL) time unit or a flexible (flexible) time unit, and a terminal may transmit uplink information on the UL subband, as shown in fig. 1. The time-frequency domain resources occupied by the UL subband may be determined by a explicit or implicit configuration, which is not limited by the present disclosure.

The time unit may be in units of a slot (slot), an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol (symbol), a subframe, a frame, etc., which is not limited in this disclosure.

For frequency hopping transmission, frequency hopping transmission in time units and across time units is supported, wherein when the time units are in the form of slots or OFDM symbols, the frequency hopping transmission comprises intra-slot (intra-slot) frequency hopping transmission and inter-slot (inter-slot) frequency hopping transmission.

When the terminal performs intra-slot frequency hopping transmission of uplink information, the terminal transmits the uplink information in a slot by taking an OFDM symbol as a unit, and the same uplink information can be divided into two parts for transmission, wherein the two parts respectively occupy different frequency domain resources.

In the present disclosure, the uplink information includes, but is not limited to, at least one of: physical uplink shared channel (PUSCH, physical Uplink Shared Channel), physical uplink control channel (Physical Uplink Control Channel, PUCCH), channel sounding reference signal (Sounding Reference Signal, SRS), and the like.

The PUSCH may be a PUSCH scheduled by a random access response (Random Access Response, RAR) message, or the PUSCH may be a PUSCH indicated by a message 3 (Msg 3), or the PUSCH may be a PUSCH indicated by indication information such as downlink control information (Downlink Control Information, DCI), a medium access control element (Media Access Control Element, MAC CE), a radio resource control (Radio Resource Control, RRC) message, or the like, which is not limited in this disclosure.

The base station may instruct, by using frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA) instruction information, frequency domain resources occupied when the terminal transmits PUSCH, taking PUSCH scheduled by an RAR message as an example, where the base station may instruct in a frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA) domain of the RAR message, including:

at the position ofOr +.>Definition +.>

Specifically, the corresponding FDRA domain may be parsed based on the lowest N bits of the FDRA domain, wherein if PUSCH enables frequency hopping, the first N of the FDRA domain except for the lowest N bits _UL,h o _p The number of bits is used to indicate the corresponding frequency hopping offset (offset);

otherwise, the front N of FDRA domain _UL,h o _p The number of bits indicates the corresponding frequency hopping offset, and when resolving, based on N bits resolving, if N is greater than 14 bits in the non-shared spectrum scene, the terminal is based on the indication information and based on the information of N _UL,h o _p Post-insertion of a number of bits0 preset bits parse. It should be noted that, the preset bits are bits added by the terminal when the terminal parses the indication information, and no corresponding modification is made to the specific indication bits.

Wherein,,equal to the number of Resource Blocks (RBs) comprised by the initial (UL) BWP. The initial uplink BWP may be a BWP frequency domain resource configured by the base station for the terminal and used when uplink transmission is performed for the first time, and may also be configured in a random access process, which is not limited in the present disclosure.

As described above, for PUSCH scheduled by the RAR message or PUSCH used to perform Msg 3 retransmission, the occupied frequency domain resources thereof may be indicated by PUSCH FDRA domain of the RAR message (FDRA domain constantly occupies 14 bits or occupies 12 bits in shared spectrum), where N _UL,h o _p The bit values of (a) are used to indicate the frequency hopping offset, and the specific correspondence is shown in table 1 below:

TABLE 1

For PUSCH resource allocation type 1, the frequency domain resources may be indicated based on a resource indication value (Resource Indication Value, RIV), the RIV being associated with a starting RB index value RB of the frequency domain resources _start And the number of continuous RBs L _RBs The associated determination is as follows:

Otherwise

Wherein L is _RBs Not less than 1 and not more than

Wherein Rb _start The number of RB intervals, L, of the starting RBs, which are frequency domain resources, compared to the BWP starting RBs _RBs The number of RBs occupied by the frequency domain resources. For example, as shown in fig. 2, the initial RB index value RB in the frequency domain resource scheduled by the base station _start Number of continuous RBs L of 7 _RBs 9 due toThen according to->This formula allows the calculation of only one RIV.

Currently PUSCH transmissions are only transmitted on time units configured as UL, whereas in SBFD scenarios, on SBFD time units, a terminal may be configured to transmit PUSCH on UL subband.

The SBFD time unit refers to a downlink time unit configured with UL and/or DL subbands, or the SBFD time unit is a flexible time unit configured with UL and/or DL subbands, as shown in fig. 1, for example. The time unit may be in units of slots, symbols, frames, subframes, which is not limited by the present disclosure.

In this embodiment, the UL subband refers to a frequency domain resource configured by the base station, where the UL subband overlaps with the uplink BWP, and the terminal may be configured to perform uplink transmission on the UL subband. And on the SBFD time unit, the frequency domain resource range occupied by the UL subband is smaller than or equal to the frequency domain resource range occupied by the UL BWP. If the frequency domain resource occupied during PUSCH frequency hopping transmission is determined based on the frequency domain resource range occupied by uplink BWP on the SBFD time unit, it is obviously inaccurate, and it is easy to cause inconsistent understanding between the terminal and the base station.

In order to solve the technical problems, the present disclosure provides the following resource determining and indicating methods and apparatuses, and a storage medium, which can determine the frequency domain resources occupied during the frequency hopping transmission of uplink information in an SBFD scene, ensure that the terminal and the base station understand the frequency domain resources consistently, and improve the feasibility and reliability of communication in the SBFD scene.

The resource determining method provided by the present disclosure is first described from the terminal side.

An embodiment of the present disclosure provides a method for determining resources, referring to fig. 3, and fig. 3 is a flowchart of a method for determining resources, which may be performed by a terminal, and may include the following steps:

in step 301, frequency domain resource indication information transmitted by a base station is received.

In the embodiment of the disclosure, the terminal may receive a first message including an FDRA domain sent by the base station, and the terminal determines the frequency domain resource indication information based on the FDRA domain. The first message may be an RAR message, msg3, DCI, MAC CE, or RRC message, which is not limited in this disclosure.

In step 302, when the uplink information is transmitted in a frequency hopping manner across time units, frequency domain resources occupied when the uplink information is transmitted are determined based on the frequency domain resource indication information.

In the disclosed embodiments, the upstream information includes, but is not limited to PUSCH, PUCCH, SRS and the like.

The terminal can determine the frequency domain resources occupied by transmitting the uplink information based on the frequency domain resource indication information when the terminal performs frequency hopping transmission of the uplink information across time units.

In one possible implementation, the frequency domain resource may be a first frequency domain resource, where the first frequency domain resource is located within a frequency domain resource range occupied by the uplink BWP.

In another possible implementation, the frequency domain resource may be a second frequency domain resource, the second frequency domain resource being located within a frequency domain resource range occupied by the first sub-band. The first sub-band is UL subband, and when the terminal is configured to perform uplink transmission on the first sub-band, the terminal needs to perform uplink transmission based on the second frequency domain resource. Illustratively, the first sub-band is located on an SBFD time unit in time domain, wherein the SBFD time unit is in units of slots (slots), symbols (symbols), frames, subframes, etc., which are not limited by the present disclosure.

When the terminal performs frequency hopping transmission on the uplink information, the terminal may transmit the uplink information on the time units of the first type and the second type at the same time, at this time, the frequency domain resources specifically used by the uplink information on the time units of different types need to be determined, and the manner of determining the corresponding frequency domain resources is described below based on the types of the different time units respectively:

in one possible implementation, the terminal determines that the frequency domain resource occupied when transmitting PUSCH is the first frequency domain resource in response to determining to be located on a time unit of a first type.

In the embodiments of the present disclosure, the first type of time unit may be a non-SBFD time unit, i.e., the first type of time unit is a time unit not belonging to the SBFD type, and illustratively, the first type of time unit may be an UL time unit. The terminal transmits uplink data in the UL BWP range based on scheduling in a first type of time unit, and the base station is not configured with UL and/or DL subbands in the time unit, where UL subbands refers to subbands in which the terminal is configured to perform uplink transmission, and DL subbands refers to subbands in which the terminal is configured to perform downlink reception.

Illustratively, the first type of time units may be uplink time units without UL and/or DL subbands, or the first type of time units may be flexible time units without UL and/or DL subbands.

On a non-SBFD time unit, a terminal can determine that frequency domain resources occupied when uplink information is transmitted are the first frequency domain resources when the uplink information is transmitted in a cross-time unit frequency hopping mode.

In another possible implementation manner, in response to determining that the terminal is located on the second type of time unit, the terminal may determine that the frequency domain resource occupied when transmitting the uplink information is the second frequency domain resource. The second type of time unit is an SBFD time unit, for example, the second type of time unit may be a time unit configured with UL and/or DL subbands.

Illustratively, the second type of time unit may be a downlink time unit configured with the first sub-band (i.e., UL subband) and/or DL subband, or may be a flexible time unit configured with the first sub-band (i.e., UL subband) and/or DL subband. And on the SBFD time unit, the terminal can determine that the frequency domain resource occupied when the uplink information is transmitted is the second frequency domain resource when the uplink information is transmitted in the cross-time unit frequency hopping transmission. The second frequency domain resource is in the UL subband range.

In one possible implementation, the frequency domain resource indication information sent by the base station may be used to directly indicate the first frequency domain resource, i.e. the base station indicates the first frequency domain resource based on the frequency domain resource range occupied by the uplink BWP. Correspondingly, if the terminal is located on the first type of time unit, the terminal directly determines the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. If the terminal is located on the second type of time unit, the terminal cannot directly determine the second frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. The present disclosure also provides a specific way of determining the second frequency domain resource at this time, which will be described in the subsequent embodiments, which will not be described here.

In another possible implementation, the frequency domain resource indication information sent by the base station may be used to directly indicate the second frequency domain resource, i.e. the base station indicates the second frequency domain resource based on the frequency domain resource range occupied by the first sub-band. Correspondingly, if the terminal is located on the second type of time unit, the terminal directly determines second frequency domain resources occupied when transmitting uplink information based on the frequency domain resource indication information. If the terminal is located on the first type of time unit, the terminal cannot directly determine the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. The present disclosure also provides a specific manner of determining the first frequency domain resource by the terminal at this time, which will also be described in the subsequent embodiments, and is not described herein.

In the embodiment, the frequency domain resources occupied when the uplink information is transmitted in a frequency hopping manner by the cross-time unit can be determined in the SBFD scene, so that the understanding of the terminal and the base station on the frequency domain resources is consistent, and the feasibility and the reliability of communication in the SBFD scene are improved.

In some alternative embodiments, frequency domain resource indication information is used to indicate the first frequency domain resource.

In one possible implementation, the frequency domain resource indication information is used to indicate at least one of: first resource indication information; first frequency hopping indication information.

The first resource indication information is used for indicating the first frequency domain resource occupied by the uplink information on a first time unit. It should be noted that the first time unit is a first type of time unit, i.e., a non-SBFD time unit.

The first frequency hopping indication information is used for indicating a first frequency domain offset of one hop on a first type of time unit relative to a previous hop on the first type of time unit when the uplink information is transmitted. For example, slot#0 and slot#1 are time units of a first type, slot#2 and slot#3 are time units of a second type, the terminal hops on the 4 slots to transmit uplink information, and the first offset is a frequency domain offset of one hop of the terminal on slot#1 relative to one hop of the terminal on slot#0.

It should be noted that, the number of bits occupied by the first frequency hopping indication information in the frequency domain resource indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

The terminal may determine n based on table 1, e.g., the number of RBs occupied by uplink BWPAnd if the value of n is greater than or equal to 50, the value of n is 2, namely the first frequency hopping indication information occupies 2 bits in the frequency domain resource indication information. For another example, a + >And if the value of n is smaller than 50, the value of n is 1, and the first frequency hopping indication information occupies 1 bit in the frequency domain resource indication information. In one example, the first time unit may include, but is not limited to, at least one of the following time units: the index value of the uplink information is an even number of time units; and the time unit where the first hop of the uplink information is located.

In one example, the first resource indication information may be used to indicate at least one of: a first starting RB number; a first RB number.

Wherein the first initial RB number is an RB number spaced apart from the initial RB of the first frequency domain resource and the initial RB of the uplink BWP.

The first RB number is the RB number included in the first frequency domain resource, that is, the RB number occupied by the uplink information.

It should be noted that the first resource indication information may be used to indicate the first starting RB number described above, and the first RB number may be determined based on a protocol convention or other predefined manner. Or the first resource indication information may be used to indicate the first number of RBs described above, which may be determined based on a protocol convention or other predefined manner. Alternatively, the first resource indication information may be used to indicate the first number of initial RBs and the first number of RBs.

For example, the first resource indication information is used to indicate uplink information, for example, PUSCH is on time units with index values of 0, 2, 4, 6, … …, and the time units are time units of a first type, the frequency domain resources occupied by the PUSCH are first frequency domain resources, and/or the first resource indication information is used to indicate uplink information, for example, first frequency domain resources occupied on time units where a first hop of the PUSCH is located.

When the terminal is located in a first time unit and the first time unit belongs to a first type of time unit, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the first frequency domain resource, and the mode of determining the first frequency domain resource is as follows:

the first frequency domain resource occupied by the first time unit index value is even number, and the first frequency domain resource is related to the first initial RB number and the first RB number.

The first frequency domain resource occupied by the first time unit with the odd index value of the first time unit is related to the first frequency domain offset indicated by the first frequency hopping indication information in addition to the first initial RB number and the first RB number.

In the present disclosure, it is assumed that Index value for the first time unit, i.e. +.>For the index value of the non-SBFD slot, the terminal may determine the index value of the start RB for transmitting uplink information on the first time unit using the following equation 1>

Wherein,,for the first initial RB number, +.>For a first frequency domain offset indicated by the first frequency hopping indication information,/a first frequency domain offset>The number of RBs occupied for upstream BWP.

It will be appreciated that the number of components,refers to a first time unit with even index value, and the index value of the initial RB of the first frequency domain resource occupied by the terminal when transmitting uplink information is determined to be +.> Refers to a first time unit with an odd index value, and determines that the index value of the initial RB of the first frequency domain resource occupied during uplink information transmission is (RB) _start +RBo _ffset )

L _RB Refers to the first number of RBs, i.e., the number of RBs included in the first frequency domain resource.

Wherein,,and L _RB Based on the range of frequency domain resources occupied by the upstream BWP. Specifically, the terminal may be determined based on the first resource indication information indicated by the frequency domain resource indication information transmitted by the base station.

Wherein,,can be determined based on table 1. For example, the value of n has been determined previously, assuming that n is 2, i.e. the first frequency hopping indication information occupies 2 bits in the frequency domain resource indication information. The bit value corresponding to the first n bits in the frequency domain resource indication information is 01, and based on table 1, the frequency hopping offset corresponding to the bit value "01" can be seen >The terminal determines a first frequency domain offset +.>

The terminal receives the index value from the first time unit with even numberRB start, occupy L _RB Transmitting uplink information from a plurality of RBs, wherein the index value is an odd number of first time unitsRB start, occupy L _RB Uplink information is transmitted by each RB, as shown with reference to fig. 4A.

And when the terminal is positioned on the second type of time unit, the terminal determines that the frequency domain resource occupied when the uplink information is transmitted is the second frequency domain resource, wherein the second frequency domain resource can be determined based on at least one of a second initial RB number, the second RB number and a second frequency domain offset. The specific determination mode is as follows:

the second frequency domain resource occupied by the terminal on the second time unit with even index value is related to a second initial RB number and a second RB number, wherein the second initial RB number is the RB number of the interval between the initial RB of the second frequency domain resource occupied by the uplink information on the second time unit and the initial RB of the first sub-band, and the second RB number is the RB number included in the second frequency domain resource occupied by the uplink information on the second time unit.

In one example, the second starting RB number may be equal to the first starting RB number.

In one example, the second number of RBs may be equal to the first number of RBs.

The second frequency domain resource occupied by the second time unit with the odd index value is related to a second frequency domain offset indicated by the second frequency hopping indication information in addition to the second initial RB number and the second RB number. Wherein the number m of bits occupied by the second frequency hopping indication information is determined based on the number of RBs occupied by the first sub-band.

The present disclosure provides that the values of table 2, m, may be determined based on table 2.

TABLE 2

For example, the number of RBs occupied by the first sub-bandGreater than or equal to 50, the value of m is 2, i.e., the second frequency hopping indication information should occupy 2 bits. For another example, a +>Less than 50, the value of m is 1 and the second frequency hopping indication information should occupy 1 bit.

In general, the number of RBs occupied by the first subband is smaller than or equal to the number of RBs occupied by the uplink BWP, so the values of m and n are the following:

in the first case, the number of RBs occupied by the first subband is equal to the number of RBs occupied by the uplink BWP and is smaller than 50, and the values of m and n are equal and are 1.

In the second case, the number of RBs occupied by the first subband is equal to the number of RBs occupied by the uplink BWP and is greater than or equal to 50, and the values of m and n are equal to each other and are both 2.

In the third case, the number of RBs occupied by the first subband is smaller than the number of RBs occupied by the uplink BWP, and the number of RBs occupied by the first subband is greater than or equal to 50, and the values of m and n are equal and are both 2.

In the fourth case, the number of RBs occupied by the first subband is smaller than the number of RBs occupied by the uplink BWP, and the number of RBs occupied by the uplink BWP is smaller than 50, and the values of m and n are equal and are both 1.

In the fifth case, the number of RBs occupied by the first subband is smaller than the number of RBs occupied by the uplink BWP, and the number of RBs occupied by the uplink BWP is greater than or equal to 50, and the number of RBs occupied by the first subband is smaller than 50, then the values of m and n are unequal, the value of m is 1, and the value of n is 2.

Based on the above, it can be seen that m.ltoreq.n.

Because the frequency domain resource indication information sent by the base station is used for indicating the first frequency domain resource, and the number n of bits occupied by the first frequency hopping indication information is greater than or equal to m, in one example, the terminal may determine the second frequency hopping indication information by using the bit values corresponding to m least significant bits in the first frequency hopping indication information. In another example, the terminal may determine the second frequency hopping indication information by using bit values corresponding to m most significant bits in the first frequency hopping indication information.

For example, if the number of bits occupied by the first frequency hopping indication information is 2, the number of bits occupied by the second frequency hopping indication information is 2, and the bit value of the first frequency hopping indication information in the frequency domain resource indication information is "10", the terminal determines that the bit value corresponding to the second frequency hopping indication information is also "10".

For another example, if the number of bits occupied by the first frequency hopping indication information is 2, the number of bits occupied by the second frequency hopping indication information is 1, and the bit value of the first frequency hopping indication information in the frequency domain resource indication information is "10", the terminal determines that the bit value corresponding to the second frequency hopping indication information is "0" (the bit value corresponding to the m least significant bits) or "1" (the bit value corresponding to the m least significant bits).

After determining the second frequency hopping indication information, the terminal may determine a second frequency domain offset based on table 2For example, slot#0 and slot#1 are time units of a first type, slot#2 and slot#3 are time units of a second type, the terminal hops on the 4 slots to transmit uplink information, and the second offset is a frequency domain offset of one hop of the terminal on slot#3 relative to one hop of the terminal on slot#2.

For example, if the terminal determines that the bit value corresponding to the second frequency hopping indication information is "10", it can be determined based on table 2, (in this disclosure, the frequency domain offset may be offset downward if it is negative). For another example, if the terminal determines that the bit value corresponding to the second frequency hopping indication information is "0", it can be determined based on table 2,

in the present disclosure, it is assumed thatIndex value for the second time unit, i.e. +.>For the index value of the SBFD slot, the terminal may determine the index value +.f of the start RB for transmitting uplink information over the second time unit using the following equation 2>

The terminal receives the index value from the second time unit with even numberRB start, occupancy->Transmitting uplink information from a plurality of RBs, wherein the index value is an odd number of second time unitsRB start, occupancy->Uplink information is transmitted by each RB, as shown with reference to fig. 4B.

In the above embodiment, the frequency domain resource indication information is a first frequency domain resource occupied when the frequency hopping transmission of the uplink information is indicated in the frequency domain resource range occupied by the uplink BWP, and the terminal can determine the frequency domain resource occupied when the frequency hopping transmission of the uplink information is performed across time units on different types of time units, so that the terminal is ensured to be consistent with the understanding of the frequency domain resource by the base station, and the feasibility and reliability of communication in the SBFD scene are improved.

In some alternative embodiments, frequency domain resource indication information is used to indicate the second frequency domain resource.

In one possible implementation, the frequency domain resource indication information is used to indicate at least one of: third resource indication information; and third frequency hopping indication information.

The third resource indication information is used for indicating the second frequency domain resource occupied by the uplink information on a second time unit. It should be noted that the second time unit is a second type of time unit, i.e., an SBFD time unit.

Wherein the third frequency hopping indication information is used for indicating a third frequency domain offset of one hop on the time unit of the second type relative to the previous hop on the time unit of the second type when the uplink information is transmitted. It should be noted that the number of bits occupied by the third frequency hopping indication information m is determined based on the number of RBs occupied by the first sub-band

The terminal may determine m based on Table 2, e.g., the number of RBs occupied by the first sub-bandGreater than or equal to 50, the value of m is 2, i.e., the second frequency hopping indication information should occupy 2 bits. For another example, a +>Less than 50, the value of m is 1 and the second frequency hopping indication information should occupy 1 bit.

In one example, the second time unit may include, but is not limited to, at least one of the following: the index value of the uplink information is an even number of time units; and the time unit where the first hop of the uplink information is located.

In one example, the third resource indication information may be used to indicate at least one of: a third starting RB number; third RB number.

Wherein the third starting RB number is an RB number spaced apart from the starting RB of the second frequency domain resource and the starting RB of the first subband.

Wherein the third RB number is the RB number included in the second frequency domain resource.

It should be noted that the third resource indication information may be used to indicate the third starting RB number described above, and the third RB number may be determined based on a protocol convention or other predefined manner. Or third resource indication information may be used to indicate the third number of RBs described above, and the third starting number of RBs may be determined based on a protocol convention or other predefined manner. Alternatively, the third resource indication information may be used to indicate a third starting RB number and a third RB number.

When the terminal is located on the second type time unit, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the second frequency domain resource, and the manner of determining the second frequency domain resource is as follows:

the second frequency domain resource occupied by the second time unit with even index value is related to the third initial RB number and the third RB number.

The second frequency domain resource occupied by the second time unit with the odd index value is related to a third frequency domain offset indicated by the third frequency hopping indication information in addition to the third initial RB number and the third RB number.

In the present disclosure, it is assumed thatIndex value for the second time unit, i.e. +.>For the index value of the SBFD slot, the terminal may determine the index value +.f of the starting RB for transmitting uplink information over the second time unit using equation 3>

Wherein,,for the third initial RB number, < >>A third frequency domain offset indicated by third frequency hopping indication information,/for>The number of RBs occupied for the first sub-band.

It can be understood that, on the second time unit with even index value, the terminal determines that the index value of the initial RB of the second frequency domain resource occupied when transmitting the uplink information isThe terminal determines that the index value of the initial RB of the second frequency domain resource occupied during the uplink information transmission is the following in the second time unit with the odd index value

Wherein,,and->Based on the range of frequency domain resources occupied by the first sub-band. In the present embodiment of the present invention, in the present embodiment,and->The determination may be based on third resource indication information indicated by the frequency domain resource indication information transmitted by the base station.

Wherein,,can be determined based on table 2. For example, the value of m is 2, that is, the third frequency hopping indication information occupies 2 bits in the frequency domain resource indication information. Ratio corresponding to the first 2 bits in the frequency domain resource indication information With a value of 01, it can be seen from Table 2 that the frequency hopping offset corresponding to the bit value "01->The terminal determines a third frequency domain offset

The terminal receives the index value from the second time unit with even numberRB start, occupancy->Transmitting uplink information from a plurality of RBs, wherein the index value is an odd number of second time unitsRB start, occupancy->The RB transmits uplink information as shown with reference to fig. 4C.

When the terminal is located on a first type of time unit, the terminal determines that the frequency domain resource occupied when transmitting the uplink information is the first frequency domain resource, wherein the first frequency domain resource can be determined based on at least one of a fourth initial RB number, the fourth RB number and a fourth frequency domain offset. The specific determination mode is as follows:

the first frequency domain resource occupied by the terminal on the first time unit with even index value is related to a fourth initial RB number and a fourth RB number, wherein the fourth initial RB number is the RB number of the interval between the initial RB of the first frequency domain resource occupied by the uplink information on the first time unit and the initial RB of the uplink BWP, and the fourth RB number is the RB number included in the first frequency domain resource occupied by the uplink information on the first time unit.

In one example, the fourth starting RB number may be equal to the third starting RB number.

In one example, the fourth number of RBs may be equal to the third number of RBs.

The first frequency domain resource occupied by the terminal on the first time unit with the odd index value is related to the fourth frequency domain offset indicated by the fourth frequency hopping indication information in addition to the fourth initial RB number and the fourth RB number. Wherein the number n of bits occupied by the fourth frequency hopping indication information is determined based on the number of RBs occupied by the uplink BWP.

In the present disclosure, the value of n may be determined based on table 1, and the specific determination manner has been described in the foregoing embodiments, which is not described herein.

It has been described that m.ltoreq.n, since the frequency domain resource indication information transmitted by the base station is used to indicate the second frequency domain resource and the number of bits m occupied by the third frequency hopping indication information is less than or equal to n, the terminal may determine that the fourth frequency hopping indication information is identical to the third frequency hopping indication information when m is equal to n in one example. In another example, when m is smaller than n, the terminal may add P preset bit values at a designated position of the third frequency hopping indication information, to obtain the fourth frequency hopping indication information.

Wherein P may be a non-negative integer.

In one example, P may be 0, at which time the terminal determines fourth frequency hopping indication information based on a correspondence between the predefined third frequency hopping indication information and the fourth frequency hopping indication information.

For example, the correspondence relationship includes: the fourth frequency hopping indication information corresponding to the third frequency hopping indication information being 0 may be 00, the fourth frequency hopping indication information corresponding to the third frequency hopping indication information being 1 may be 01, and the terminal may determine that the corresponding fourth frequency hopping indication information is "00" based on the third frequency hopping indication information "0" and the correspondence relationship.

For another example, the correspondence relationship includes: the fourth frequency hopping indication information corresponding to the third frequency hopping indication information being 0 may be 10, the fourth frequency hopping indication information corresponding to the third frequency hopping indication information being 1 may be 11, and the terminal may determine that the corresponding fourth frequency hopping indication information is "10" based on the third frequency hopping indication information "0" and the correspondence relationship.

The foregoing is merely exemplary, and other ways of determining P and then determining the fourth frequency hopping indication information in practical applications shall fall within the scope of the present disclosure.

In another example, P may be (n-m), and the designated position may be a position before, after, or in the middle of the third frequency hopping indication information, which is not limited by the present disclosure. The preset bit value may be 0 or 1, preferably the preset bit value is 0. It should be noted that, the preset bits are bits added by the terminal when analyzing the indication information, and do not change the specific indication bits of the base station correspondingly.

For example, the third frequency hopping indication information indicated by the base station occupies m bits, m is 1, the corresponding bit value is "0", the value of n is 2, and the terminal may add a preset bit value before or after "0" to obtain fourth frequency hopping indication information, for example, the fourth frequency hopping indication information is "00" or "10".

In another example, when m is smaller than n, the terminal may obtain the fourth frequency hopping indication information based on a predefined relationship between the third frequency hopping indication information and the fourth frequency hopping indication information, for example, a protocol agreed correspondence relationship, and based on the third frequency hopping indication information, where one possible exemplary relationship may be as shown in table 3 or table 4:

Table 4 correspondence between fourth and third frequency hopping indication information when m is less than n

		0	10 or 01
1	11

It should be noted that the predefined relationship of table 3 or table 4 is an exemplary description of one of the corresponding relationships, and other corresponding relationships are also within the scope of the present invention.

After determining the fourth frequency hopping indication information, the terminal may determine a fourth frequency domain offset based on table 1

For example, the bit value corresponding to the fourth frequency hopping indication information is "10", it can be determined based on table 1,(in this disclosure, the frequency domain offset may be offset downward if it is negative).

In the above embodiment, the frequency domain resource indication information is a second frequency domain resource occupied when the frequency hopping transmission of the uplink information is indicated in the frequency domain resource range occupied by the first sub-band, and the terminal can determine the frequency domain resource occupied when the frequency hopping transmission of the uplink information is performed across time units on different types of time units, so that the terminal is ensured to be consistent with the understanding of the frequency domain resource by the base station, and the feasibility and reliability of communication in the SBFD scene are improved.

In some alternative embodiments, when the terminal transmits uplink information across time units, two types of time units may be encountered, and when frequency domain resource indication information is used to indicate the first frequency domain resource, the terminal may determine the corresponding frequency domain resource in the following manner:

The first frequency hopping indication information is used for indicating a third frequency domain offset of one hop on a time unit of a first type relative to a previous hop on the time unit of the first type when the uplink information is transmitted. It should be noted that, the number of bits occupied by the first frequency hopping indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

In one example, the first time unit may include, but is not limited to, at least one of the following time units: the index value of the uplink information is an even number of time units; and the time unit where the first hop of the uplink information is located.

When the terminal is located on a first type of time unit, i.e. on a non-SBFD time unit, the terminal may determine the first frequency domain resources occupied when transmitting the uplink information based on the following mechanism:

in the present disclosure, it is assumed thatFor indicating the hop count index value at the first time unit, the terminal may determine the index value +.f of the starting RB for transmitting uplink information at the first time unit using equation 5>

For example, in fig. 5A, the first time unit includes slot #0 and slot #2, thenFor indicating a first jump on the first time unit slot #0 when 0,/is 0>And 1 for indicating a second hop on the first time unit slot # 2.

In one example, the first resource indication information included in the frequency domain resource indication information transmitted by the base station may be used to indicate at least one of: a first starting RB number; a first RB number.

Assume that uplink information is transmitted in a frequency hopping manner on slots #0 to #3, wherein only slots #0 and #2 are first time units, namely non-SBFD time units, and the first frequency hopping indication information indicates a first frequency domain offset of one hop of the uplink information on slot #2 relative to one hop on slot #0, as shown in fig. 5A.

The number of bits occupied by the first frequency hopping indication information in the frequency domain resource indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

For example, when the number of RBs occupied by the uplink BWP is less than 50, referring to table 1, n is 1, the specific bit value of which can be determined by the terminal based on the bit value of the first n bits in the frequency domain resource indication information, since n is 1, assuming that the bit value of the first 1 bits in the frequency domain resource indication information is 0, according to table 1, the frequency hopping offset (offset) isAt this time the terminal can determine the first hopping offset +.>

For another example, when the number of RBs occupied by the uplink BWP is greater than or equal to 50, referring to table 1, n is 2, the specific bit value of which can be determined by the terminal based on the bit value of the first n bits in the frequency domain resource indication information, since n is 2, assuming that the bit value of the first 2 bits in the frequency domain resource indication information is 01, according to table 1, the frequency hopping offset isAt this time the terminal can determine the first hopping offset +.> The number of RBs occupied for upstream BWP.

The number of bits occupied by the second frequency hopping indication information is m, and m is determined based on the number of RBs occupied by the first sub-band. m is less than or equal to n.

Illustratively, the uplink information adopts a resource allocation type 1 (type), and the first resource indication information may be a first RIV. The terminal determines a starting RB number and a continuous RB number corresponding to the first RIV based on the corresponding relation between different RIVs and different starting RB numbers and continuous RB numbers, determines the determined starting RB number as the first starting RB number, and determines the determined continuous RB number as the first RB number.

Assume that the first initial RB number RB is determined based on the frequency domain resource indication information _start The first RB number is L _RB Referring to fig. 5B, on the uplink BWP (assuming that the initial RB index value of the uplink BWP is 0), the terminal determines the first frequency domain resource occupied by the first hop on slot #0 includes: from RB _start Initially, the number of continuously occupied RBs is L _RB Is not included in the (a) and (b) is not included in the (b).

In addition, the first frequency domain resources occupied by the second hop of the terminal on slot#2 include: from the slaveInitially, the number of continuously occupied RBs is L _RB Is not included in the (a) and (b) is not included in the (b). Wherein (1)>For the first frequency domain offset indicated by the first frequency hopping indication information, reference is also made to fig. 5B. />

Or alternativelyThe first frequency domain resources occupied by the second hop of the terminal on slot #2 may take a negative value include: slave (RB) _start ―RB _offset ) Initially, the number of continuously occupied RBs is L _RB Is not included in the (a) and (b) is not included in the (b). Wherein (1)>A first frequency domain offset (not shown in fig. 5B) indicated for the first frequency hopping indication information.

first, the terminal may determine a second starting RB number, which is the number of RBs spaced apart from the starting RBs of the first subband by the second frequency domain resource.

In one example, the second starting RB number may be equal to the first starting RB number described above.

Of course, the second initial RB number may also have an association relationship with the first initial RB number, for example, offset again based on the first initial RB number, which is not limited in the present disclosure.

The first number of RBs previously determined is illustratively RB _start The terminal determines a second initial RB number

Second, the terminal may determine a second number of RBs, which is the number of RBs included in the second frequency domain resource.

In one example, the second number of RBs may be equal to the first number of RBs described above.

Illustratively, the first RB number previously determined is L _RB The terminal determines a second RB number

Again, the terminal may determine second frequency hopping indication information indicating a second frequency domain offset of one hop on a second type of time unit relative to a previous hop on the second type of time unit when the uplink information is transmitted.

Wherein the number m of bits occupied by the second frequency hopping indication information may be determined based on the number of RBs occupied by the first sub-band.

In the embodiment of the disclosure, the number of RBs occupied by the first sub-bandSecond frequency hopping indication information->The bit values (bit values of m bits) of the corresponding indication of the frequency hopping offset can be referred to as shown in table 2 above.

In one example, since the frequency domain resource indication information is indicated based on the uplink BWP and m is less than or equal to n, after determining the first frequency hopping indication information (the number of occupied bits is n), the terminal may determine the second frequency hopping indication information based on bit values corresponding to m least significant bits in the first frequency hopping indication information.

For example, m and N are equal to 2, and the first frequency hopping indication information N _UL,h o _p The bit value corresponding to the N least significant bits in the sequence is 01, namely the first frequency hopping indication information N _UL，hop The terminal determines the first frequency hopping indication information N if the bit value of (a) is 01 _UL，hop The bit value corresponding to the m least significant bits in the data is also 01, namely the second frequency hopping indication informationThe corresponding bit value is 01, and the second frequency domain offset +.>

For another example, m is smaller than N, and the first frequency hopping indication information N _UL,hop The terminal determines the first frequency hopping indication information N if the bit value corresponding to the N least significant bits in the plurality of bits is 01 _UL，hop The bit value corresponding to the m least significant bits in the data is also 1, namely the second frequency hopping indication informationThe corresponding bit value is 1, based on which table 2 a second frequency domain offset +.>At this time

In another example, since the frequency domain resource indication information is indicated based on the uplink BWP and m is less than or equal to n, after determining the first frequency hopping indication information (the number of occupied bits is n), the terminal may determine the second frequency hopping indication information based on bit values corresponding to m most significant bits in the first frequency hopping indication information.

For example, if m is equal to n and is equal to 2, and the bit value corresponding to the n most significant bits in the first frequency hopping indication information is 01, the terminal determines that the bit value corresponding to the m most significant bits in the first frequency hopping indication information is also 01, and based on table 2, can determine the second frequency domain offset And at this time->

For another example, if m is smaller than n and the bit value corresponding to the n most significant bits in the first frequency hopping indication information is 01, the terminal determines that the bit value corresponding to the m most significant bits in the first frequency hopping indication information is also 0, and based on table 2, the second frequency domain offset can be determinedAt this time->

The present disclosure is not limited to the above-described determination of the second start RB number, the second RB number, and the execution order of the second frequency hopping indication information.

After determining the second start RB number, the second RB number, and the second frequency hopping indication information, the terminal may determine the second frequency domain resource according to the following equation 6 based on at least one of the second start RB number, the second RB number, and the second frequency domain offset:

wherein,,are 0, 1, 2, 3, … … for indicating hop 1, hop 2, hop 3, hop 4, etc., respectively, on the second time unit.

It will be appreciated that the number of components,refers to odd hops, e.g. 1, 3 … … hops, refers to even hops, e.g., hops 2, 4 … …, over a second time unit.

For example, in fig. 5A, the second time unit includes slot #1 and slot #3, thenFor indicating a first hop on the second time unit when 0 and which is located on slot #1,/on slot #1 >And 1 for indicating a second hop on a second time unit, the second hop being located on slot # 3.

For example, as shown in fig. 5C, it is assumed that the first starting RB number RB is determined based on the frequency domain resource indicating information _start The first RB number is L _RB The terminal may determine a second starting RB numberSecond RB numberThe terminal is on the first subband (assuming that the initial RB index value of the first subband is also 0), the terminal determines that the first hop on the second time unit is on slot #1, and the occupied second frequency domain resource includes: from->Initially, the number of RBs occupied continuously is +.>Is not included in the (a) and (b) is not included in the (b).

In addition, the second hop of the terminal on the second time unit is located on slot#3, and the occupied second frequency domain resources include: from the slave Initially, the number of RBs occupied continuously is +.>Is not included in the (a) and (b) is not included in the (b). Wherein (1)>And a second frequency domain offset indicated by the second frequency hopping indication information.

Or alternativelyThe first frequency domain resources occupied by the second hop of the terminal on slot #2 may take a negative value include: from-> Initially, the number of RBs occupied continuously is +.>Is not included in the (a) and (b) is not included in the (b). Wherein (1)>A first frequency domain offset indicated for the first frequency hopping indication information (not shown in fig. 5C).

I.e., the terminal may determine the starting RB of the second frequency domain resource using equation 6 on slot #1 and slot # 3.

In some alternative embodiments, when the terminal transmits uplink information across time units, two types of time units may be encountered, and when frequency domain resource indication information is used to indicate the second frequency domain resource, the terminal may determine the corresponding frequency domain resource in the following manner:

Wherein the third frequency hopping indication information is used for indicating a third frequency domain offset of one hop on the time unit of the second type relative to the previous hop on the time unit of the second type when the uplink information is transmitted. It should be noted that, the number of bits occupied by the third frequency hopping indication information is m, and m is determined based on the number of RBs occupied by the first subband.

For example, the third resource indication information is used to indicate the second frequency domain resources occupied by the uplink information, for example, PUSCH, on the time units with index values of 0, 2, 4, 6, … …, and/or the third resource indication information is used to indicate the second frequency domain resources occupied by the uplink information, for example, PUSCH, on the time units where the first hop is located.

Illustratively, it is assumed that uplink information is transmitted in a frequency hopping manner on slots #0 to #3, wherein only slots #1 and #3 are second time units, that is, SBFD time units, and the third frequency hopping indication information indicates a third frequency domain offset of one hop of the uplink information on slot #3 relative to one hop on slot #1, as shown with reference to fig. 5D.

The number of bits occupied by the third frequency hopping indication information in the frequency domain resource indication information is m, and m is determined based on the number of RBs occupied by the first sub-band.

For example, when the number of RBs occupied by the first sub-band is less than 50, referring to table 2, the value of m is 1, the specific bit value of which can be determined by the terminal based on the bit value of the first m bits in the frequency domain resource indication information, and since m is 1, it is assumed that the bit value of the first 1 bits in the frequency domain resource indication information is 0, i.e., the third frequency domain indication information Has a bit value of 1, and the frequency hopping offset is +.>At this time, the terminal can determine a third frequency hopping offset

For another example, when the number of RBs occupied by the first sub-band is 50 or more, referring to Table 2, m is 2, which is a specific ratioThe value may be determined by the terminal based on the bit value of the first m bits in the frequency domain resource indication information, assuming that the bit value of the first 2 bits in the frequency domain resource indication information is 10, i.e. the third frequency domain indication informationHas a bit value of 10, and the frequency hopping offset is +.> At this time, the terminal can determine a third frequency hopping offset

When the terminal is located on a second type of time unit, i.e. on an SBFD time unit, the terminal may determine the second frequency domain resources occupied when transmitting the uplink information based on the following mechanism:

Wherein,,are 0, 1, 2, 3 … … for indicating hop 1, hop 2, hop 3, hop 4, etc., respectively, on the second time unit.

Illustratively, the uplink information adopts a resource allocation type 1 (type), and the third resource indication information may be a second RIV. The terminal determines a starting RB number and a sustaining RB number corresponding to the second RIV based on correspondence between different RIVs and different starting RB numbers and sustaining RB numbers, and determines the determined starting RB number as a third starting RB number and the determined sustaining RB number as a third RB number.

Assume that the third starting RB number is determined based on the frequency domain resource indication informationThe third RB number is +.>Referring to fig. 5E, on the first subband (assuming that the starting RB index value of the first subband is 0), the terminal determines that the first hop on the second time unit is located on slot #1, and the second frequency domain resources occupied on the first hop include: from- >Initially, the number of RBs occupied continuously is +.>Is not included in the (a) and (b) is not included in the (b).

In addition, the second hop of the terminal on the second time unit is located on slot#3, and the occupied second frequency domain resources include: from the slave Initially, the number of RBs occupied continuously is +.>Is not included in the (a) and (b) is not included in the (b). Wherein (1)>And a third frequency domain offset indicated by the third frequency hopping indication information.

Wherein (1)>A first frequency domain offset indicated for the first frequency hopping indication information (not shown in fig. 5E).

When the terminal is located on the first type of time unit, that is, on the non-SBFD time unit, the terminal may determine first frequency domain resources occupied when transmitting the uplink information based on the fourth number of start RBs, the fourth number of RBs, and fourth frequency hopping indication information:

first, the terminal may determine a fourth start RB number, which is the RB number separated from the start RB of the first frequency domain resource and the start RB of the uplink BWP.

In one example, the fourth starting RB number may be equal to the third starting RB number described above.

Of course, the fourth initial RB number may also have an association relationship with the third initial RB number, for example, offset again based on the third initial RB number, which is not limited in the present disclosure.

The third initial RB number determined previously is illustrativelyThe terminal determines a fourth initial RB number

Second, the terminal may determine a fourth RB number, which is the number of RBs included in the first frequency domain resource.

In one example, the fourth number of RBs may be equal to the third number of RBs described above.

Illustratively, the previously determined third RB number isTerminal determines the fourth RB number +.>

Again, the terminal may determine fourth frequency hopping indication information indicating a fourth frequency domain offset of one hop on the first type of time unit with respect to a previous hop on the first type of time unit when the uplink information is transmitted.

Wherein, the number n of bits occupied by the fourth frequency hopping indication information may be determined based on the number of RBs occupied by the uplink BWP.

As previously analyzed, m.ltoreq.n.

In the embodiment of the present disclosure, the frequency domain resource indication information sent by the base station indicates third frequency hopping indication information with m occupied bits. The frequency resource indication information in the foregoing embodiment indicates first frequency hopping indication information with n occupied bits.

In one example, if the terminal determines that m is equal to n, the terminal may determine that fourth frequency hopping indication information is identical to the third frequency hopping indication information. Correspondingly, the fourth frequency domain offset Offset from the third frequency domain>Equal.

In another example, if the terminal determines that m is less than n, the terminal may add P preset bit values at a designated position of the third frequency hopping indication information, to obtain the fourth frequency hopping indication information. It should be noted that, the preset bits are bits added by the terminal when the terminal parses the indication information, and no corresponding modification is made to the specific indication bits.

Illustratively, the designated position may be a bit before or after the third frequency hopping indication information.

Illustratively, the preset bit value may be 0 or 1. In the present disclosure, preferably, the preset bit value may be 0.

Illustratively, P may be a non-negative integer.

In one example, P may be 0, at which time the terminal determines fourth frequency hopping indication information based on a correspondence between the predefined third frequency hopping indication information and the fourth frequency hopping indication information. The correspondence may be shown in table 3 or table 4, and the scheme of determining the fourth frequency hopping indication information based on table 3 or table 4 has been described in the above embodiment, and will not be described herein.

For example, m is 1, n is 2, p is 0, the bit value corresponding to the third hopping indication information is 1, and it can be determined that the fourth hopping indication information is 01 based on table 3.

In another example, P may be (n-m).

For example, m is 1, n is 2, the bit value corresponding to the third frequency hopping indication information is 0, the preset position is the bit before the third frequency hopping indication information, the preset bit value is 0, and the terminal obtains the fourth frequency hopping indication information as 00.

Further, the terminal may determine a fourth frequency domain offset indicated by the fourth frequency hopping indication information based on table 1

For example, the fourth frequency hopping indication information is 10, and the fourth frequency domain offset can be determined based on table 2

The present disclosure is not limited to the above-described determination of the fourth number of start RBs, the fourth number of RBs, and the fourth frequency hopping indication information.

Determination on uplink BWP or uplink sub-bandThe manner of the above has been described in the foregoing embodiments, and will not be described in detail here.

In the above embodiment, whether the frequency domain resource indication information is a first frequency domain resource occupied when the frequency hopping transmission of the uplink information is indicated in the frequency domain resource range occupied by the uplink BWP or a second frequency domain resource occupied when the frequency hopping transmission of the uplink information is indicated in the frequency domain resource range occupied by the uplink sub-band, the terminal can determine the frequency domain resource occupied when the frequency hopping transmission of the uplink information is performed across time units on different types of time units, so as to ensure that the understanding of the frequency domain resource by the terminal and the base station is consistent, and improve the feasibility and reliability of communication in the SBFD scene. The resource indication method provided by the present disclosure is introduced from the base station side.

An embodiment of the present disclosure provides a resource indication method, referring to fig. 6, and fig. 6 is a flowchart of a resource indication method, which may be performed by a base station, according to an embodiment, and the method may include the following steps:

in step 601, frequency domain resource indication information is sent to a terminal in response to scheduling cross-time unit frequency hopping transmission of uplink information for the terminal.

In the embodiment of the present disclosure, the frequency domain resource indication information is used for determining, by the terminal, a frequency domain resource occupied when transmitting the uplink information, where the frequency domain resource is a first frequency domain resource located in a frequency domain resource range occupied by the uplink partial bandwidth BWP or a second frequency domain resource located in a frequency domain resource range occupied by the first subband.

In one possible implementation, the base station sends a first message including the FDRA domain to the terminal, where the first message may be a RAR message, which is not limited by the present disclosure. And sending the frequency domain resource indication information to the terminal through the FDRA domain.

In one possible implementation, the upstream information includes, but is not limited to PUSCH, PUCCH, SRS, etc.

After receiving the frequency domain resource indication information, the terminal determines frequency domain resources occupied when transmitting the uplink information based on the frequency domain resource indication information when performing frequency hopping transmission of the uplink information across time units.

In another possible implementation, the frequency domain resource may be a second frequency domain resource, the second frequency domain resource being located within a frequency domain resource range occupied by the first sub-band. The first sub-band is UL subband, and when the terminal is configured to perform uplink transmission on the first sub-band, the terminal needs to perform uplink transmission based on the second frequency domain resource. Illustratively, the first sub-band is located on an SBFD time unit in time domain, wherein the SBFD time unit is in units of slots (slots), symbols (symbols), frames, subframes, etc., which are not limited by the present disclosure. In one possible implementation, the base station determines that the frequency domain resource occupied by the terminal when transmitting PUSCH is the first frequency domain resource in response to determining that the terminal is located on a first type of time unit.

In an embodiment of the present disclosure, the first type of time units is non-SBFD time units, i.e. the first type of time units are time units not belonging to the SBFD type.

In another possible implementation manner, in response to determining that the terminal is located on the second type of time unit, the base station may determine that the frequency domain resource occupied by the terminal when transmitting the uplink information is the second frequency domain resource. Wherein the second type of time unit is an SBFD time unit.

The meanings of the non-SBFD time units and SBFD time units have been described on the terminal side and will not be repeated here.

In one possible implementation, the frequency domain resource indication information sent by the base station may be used to directly indicate the first frequency domain resource, i.e. the base station indicates the first frequency domain resource based on the frequency domain resource range occupied by the uplink BWP. Correspondingly, if the terminal is located on the first type of time unit, the terminal directly determines the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information. If the terminal is located on the second type of time unit, the terminal cannot directly determine the second frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information.

In another possible implementation, the frequency domain resource indication information sent by the base station may be used to directly indicate the second frequency domain resource, i.e. the base station indicates the second frequency domain resource based on the frequency domain resource range occupied by the first sub-band. Correspondingly, if the terminal is located on the second type of time unit, the terminal directly determines second frequency domain resources occupied when transmitting uplink information based on the frequency domain resource indication information. If the terminal is located on the first type of time unit, the terminal cannot directly determine the first frequency domain resource occupied when transmitting the uplink information based on the frequency domain resource indication information.

In some alternative embodiments, the frequency domain resource indication information sent by the base station is used to indicate the first frequency domain resource.

The first frequency hopping indication information is used for indicating a first frequency domain offset of one hop on a first type of time unit relative to a previous hop on the first type of time unit when the uplink information is transmitted. It should be noted that, the number of bits occupied by the first frequency hopping indication information in the frequency domain resource indication information is n, and n is determined based on the number of RBs occupied by the uplink BWP.

Illustratively, the uplink information adopts a resource allocation type 1 (type), and the first resource indication information may be a first RIV. The base station determines a first RIV based on the corresponding relation between different RIVs, different initial RB numbers and different continuous RB numbers, and then sends the first RIV as first resource indication information to the terminal.

When the base station determines that the terminal is located on the first type of time unit, that is, on the non-SBFD time unit, the base station may determine the first frequency domain resource occupied when the terminal transmits the uplink information, and a specific determination manner is similar to a manner that the terminal side determines the first frequency domain resource based on the frequency domain resource indication information, which is not described herein again.

When the terminal is determined to be located on the second type of time unit, that is, on the SBFD time unit, the base station may determine the second frequency domain resource occupied when the terminal transmits the uplink information, and the specific determination manner is similar to that of the terminal determining the second frequency domain resource, which is not described herein.

In the above embodiment, the frequency domain resource indication information is a first frequency domain resource occupied when indicating the frequency hopping transmission of the uplink information in the frequency domain resource range occupied by the uplink BWP, and the base station may determine that the terminal is located on a time unit of a different type, and the frequency domain resource occupied when transmitting the uplink information across the time unit, so as to ensure that the understanding of the terminal and the base station on the frequency domain resource is consistent, and improve the feasibility and reliability of communication in the SBFD scenario.

In some alternative embodiments, the frequency domain resource indication information sent by the base station is used to indicate the second frequency domain resource.

Wherein the third starting RB number is an RB number spaced apart from the starting RB of the first subband by the second frequency domain resource.

For example, if the uplink information adopts the resource allocation type 1 (type), the base station determines the second RIV and then sends the second RIV to the terminal as the third resource indication information.

When the base station determines that the terminal is located on the second type of time unit, that is, on the SBFD time unit, the base station determines the second frequency domain resource occupied when the terminal transmits the uplink information, and the specific determination manner is similar to that of the terminal determining the second frequency domain resource based on the frequency domain resource indication information, which is not described herein.

When the base station determines that the terminal is located on the first type of time unit, that is, on the non-SBFD time unit, the base station determines the first frequency domain resource occupied when transmitting the uplink information, and the specific determination manner is similar to that of the terminal side for determining the first frequency domain resource, which is not described herein again.

In the above embodiment, the frequency domain resource indication information is a second frequency domain resource occupied when the frequency hopping transmission of the uplink information is indicated in the frequency domain resource range occupied by the first sub-band, and the base station can determine that the terminal is located on different types of time units, and frequency domain resources occupied when the uplink information is transmitted in a frequency hopping manner across the time units, so that the understanding of the terminal and the base station on the frequency domain resources is consistent, and the feasibility and reliability of communication in the SBFD scene are improved.

For ease of understanding, the following will describe specific embodiments of the present invention from a terminal perspective:

In embodiment 1, assume that the terminal is Rel18 and the subsequent version terminals, and the terminal is a terminal supporting SBFD characteristics, and the terminal transmits uplink information on the first subband in the DL time unit or the flexible time unit based on the base station configuration.

As described above, the embodiment of the present invention will be described taking the PUSCH as an example. The PUSCH may be a PUSCH scheduled by the RAR message, and/or a PUSCH indicated by other indication signaling such as Msg3, DCI, MAC CE, RRC, etc., which will not be described in detail herein.

In this embodiment, the terminal determines the FDRA domain indicated in the signaling such as RAR based on the configuration UL BWP on the basis of considering that the Msg3 is based on inter-slot or intra-slot frequency hopping, thereby determining the frequency domain resource indication information. If the terminal is located on the SBFD time unit, the terminal performs uplink information transmission in a frequency domain resource range occupied by a first sub-band, where the first sub-band is UL subband, and UL subband is a frequency domain resource range formed by an intersection of a sub-band configured to perform uplink transmission and UL BWP in a frequency domain range, that is, the frequency domain resource range occupied by the first sub-band in which the terminal performs uplink information transmission is smaller than or equal to the frequency domain resource range occupied by UL BWP.

If the terminal is on the slot (or symbol) where the first type of time unit, i.e. the non-SBFD, is located, the terminal determines the frequency domain resource occupied by PUSCH transmission based on UL BWP and the FDRA domain of the indication signaling. For example, the first RB number L is directly determined based on the frequency domain resource indication information _RB And a first initial RB number RB _start . Wherein L is _RB Number of RBs included for PUSCH transmission, RBs _start The number of RBs spaced between the initial RBs of the first frequency domain resource and the initial RBs of the uplink BWP corresponds to the first frequency domain offsetCan be determined based on table 1.

Wherein N is _UL,h o _p The corresponding bit values are indicated by the FDRA domain corresponding bits.

The first frequency domain resource occupied by the terminal transmitting PUSCH is determined based on equation 1.

The terminal determines a second frequency domain resource occupied by PUSCH transmission on a second type of time unit, that is, on a slot (or symbol) where the SBFD is located, based on the following method:

second initial RB numberWherein the second initial RB number +.>The number of RBs spaced from the PUSCH transmission start location (i.e., the starting RBs of the second frequency domain resource) relative to the starting RBs of the first sub-band;

The second frequency domain resource occupied on the SBFD slot is determined based on equation 2.

Based on the above analysis, the scheme of the invention is specifically described as follows:

In this embodiment, the terminal determines the FDRA domain indicated in the signaling such as RAR based on the first subband in the configured UL BWP range on the basis of considering that Msg 3 is based on inter-slot or intra-slot frequency hopping, thereby determining the frequency domain resource indication information. If the terminal is in the SBFD time unit, the terminal performs uplink information transmission in a frequency domain resource range occupied by a first sub-band, where the first sub-band is UL subband, and UL subband is a frequency domain resource range formed by an intersection of a sub-band configured to perform uplink transmission and UL BWP in a frequency domain range, that is, the frequency domain resource range occupied by the first sub-band in which the terminal performs uplink information transmission is smaller than or equal to the frequency domain resource range occupied by UL BWP.

If the terminal is on a second type time unit, that is, on a slot (or symbol) where the SBFD is located, the terminal determines, based on the first subband and the FDRA domain of the indication signaling, a frequency domain resource occupied by PUSCH transmission. For example, the third RB number is directly determined based on the frequency domain resource indication informationAnd third starting RB number->Wherein (1)>Number of RBs included for PUSCH transmission, +.>The number of RBs spaced between the starting RBs of the second frequency domain resource and the starting RBs of the first sub-band corresponds to a third frequency domain offset +. >The determination may be based on table 2:

the second frequency domain location resource occupied on the SBFD slot is based on equation 3.

The terminal determines a first frequency domain resource occupied by PUSCH transmission on a first type of time unit, namely on the slot where the non-SBFD is located, based on the following method:

fourth number of initial RBsWherein RB is _start ' is the number of RBs spaced from the PUSCH transmission start location (i.e., the start RB of the first frequency domain resource) with respect to the start RB of the UL BWP.

Fourth RB numberWherein L is _RB ' is the number of RBs included in PUSCH transmission, i.e., the number of RBs included in the first frequency domain resource.
