Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

Referring to fig. 1, fig. 1 is a schematic flowchart of a transmission configuration method based on pre-scheduling according to an embodiment of the present invention, where the method is applied to a network side device, which may be a base station specifically, and includes the following steps:

step 11: and sending configuration information to a terminal, wherein the configuration information at least comprises information of frequency hopping resources, so that the terminal can determine a transmission parameter corresponding to each frequency hopping resource according to the configuration information, and the transmission parameter comprises at least one of a MAsignature, an MA code word and a DMRS port.

In the embodiment of the present invention, a method for determining transmission parameters based on pre-scheduling is provided, that is, a network side device sends information including at least frequency hopping resources to a terminal side, so that the terminal can determine transmission parameters corresponding to each frequency hopping resource according to the configuration information, where the transmission parameters include at least one of MA signature, MA codeword, and DMRS port. Therefore, the uniformity among all communication base stations is improved, the management is convenient, and the difficulty of switching the terminal among all the base stations is reduced. In addition, compared with the transmission based on pre-scheduling without adopting a frequency hopping mode, the adoption of the frequency hopping mode can reduce the interfered probability of data transmission, improve the transmission effect and improve the confidentiality of data.

The MA signature and the MA codeword are substantially the same parameter, and therefore, only one of the MA signature and the MA codeword needs to be configured.

In addition, in this embodiment of the present invention, the configuration information further includes a frequency hopping period, and the information of the frequency hopping resource may specifically be information of the frequency hopping resource within one frequency hopping period.

The following illustrates the transmission configuration method based on the pre-scheduling.

Specifically, the configuration information further includes a frequency hopping pattern adopted by the transmission based on the pre-scheduling: an intra-slot frequency hopping (intra-slot) mode or an inter-slot frequency hopping (inter-slot) mode. See in particular 3GPP (third generation Partnership project) communication protocols 38.214 and 38.331. The configuration signaling given in protocol 38.331 is as follows:

wherein, mode 1 is frequency hopping in time slot, and mode 2 is frequency hopping between time slots.

In an optional specific embodiment, the frequency hopping resource includes at least two frequency hopping resources, the configuration information further includes the transmission parameter corresponding to each of the frequency hopping resources, and when the frequency domain positions of the frequency hopping resources are different, the corresponding transmission parameters are different. For example, if the transmission parameter includes an MA signature, the MA signature corresponding to each frequency hopping resource may be one or multiple.

When configuring a pre-scheduled NOMA transmission mode, if MAsignature (or MA codeword) or DMRS (Demodulation Reference Signal) ports of two or more users (terminals) are the same, the receiver may not be able to recover data of the users (terminals) due to collision of the MA signature (or MA codeword) or DMRS ports, which affects data reception performance. Therefore, in order to solve the technical problem, in the embodiments of the present invention, it is preferable to make the frequency hopping resources with different frequency domain positions correspond to different transmission parameters.

For example, as shown in fig. 2, when the prescheduled transmission adopts an intra-slot frequency hopping pattern and two frequency hops are shared in one slot, the expression of the frequency domain RB (Resource Block) starting positions of two frequency hopping resources allocated by the base station is as follows:

wherein First hop denotes a First frequency hop, Second hop denotes a Second frequency hop,

frequency domain RB starting position, RB, representing the first hopping resource_offsetIndicating a frequency domain RB offset value between the second hopping resource and the first hopping resource,

representing the size of the hopping bandwidth.

The base station explicitly configures two different MA signatures for the two frequency hopping sequences, that is, the configuration information includes two different MA signatures, such as MA signature1 and MA signature2, where MA signature1 is used for data transmission of a first frequency hopping sequence, and MA signature2 is used for data transmission of a second frequency hopping sequence. Specifically, a field for configuring the two different MA signatures may be added to a pre-scheduled configuration signaling (ConfiguredGrantConfig), for example, the configuration signaling may be:

as shown in fig. 3, when the pre-scheduled transmission adopts an inter-slot frequency hopping pattern and there are four hopping frequencies within one hopping period, the frequency domain RB starting positions of the four hopping resources allocated by the base station are expressed as follows:

wherein,

indicating the slot number, RB_startFrequency domain RB starting position, RB, representing frequency hopping resource with even number of time slots_offsetDenotes a frequency domain RB offset value between adjacent two hopping resources,

representing the size of the hopping bandwidth.

The base station may explicitly configure four different MA signatures for the four hopping frequencies (i.e. four slots), that is, the configuration information includes four different MA signatures, such as MA signature1, MA signature2, MA signature3, and MA signature4, where MA signature1 is used for data transmission of the first hopping frequency (e.g. nth slot), MA signature2 is used for data transmission of the second hopping frequency (e.g. n +1 th slot), MA signature3 is used for data transmission of the third hopping frequency (e.g. n +2 th slot), and MA signature4 is used for data transmission of the fourth hopping frequency (e.g. n +3 th slot).

Further, in the frequency hopping resources, the frequency hopping resources with the same frequency domain position correspond to the same transmission parameters. In the embodiment of the invention, in order to reduce signaling overhead required by configuration and ensure that frequency hopping resources with different frequency domain positions can correspond to different transmission parameters as far as possible, the same transmission parameters can be configured for the frequency hopping resources with the same frequency domain positions when the transmission parameters are explicitly configured.

For example, as shown in fig. 3, when the transmission based on the pre-scheduling adopts an inter-slot frequency hopping pattern and there are four frequency hops in one frequency hopping period, the base station may explicitly configure two different masignatures for the four frequency hops (i.e., four time slots), that is, the configuration information includes two different MA signatures, such as MA signature1 and MAsignature 2. Wherein, since the frequency domain positions of the first frequency hopping (for example, the nth time slot) and the third frequency hopping (for example, the n +2 th time slot) are the same, the MA signature1 is used for data transmission of the first frequency hopping and the third frequency hopping; since the frequency domain locations of the second hopping frequency (e.g., the (n + 1) th time slot) and the fourth hopping frequency (e.g., the (n +3) th time slot) are the same, the signature2 is used for data transmission of the second hopping frequency and the fourth hopping frequency.

In the above embodiment, the configuration information sent by the base station to the terminal for configuring the transmission parameter based on the pre-scheduling explicitly includes all transmission parameters (at least one of MA signature, MA codeword, and DMRS port) used by the terminal, and the configuration manner is simple and direct, but the signaling overhead required for configuration is large.

In order to reduce signaling overhead required for configuring transmission based on pre-scheduling, the present invention further provides an optional embodiment, where the configuration information further includes first information, and the first information enables the terminal to determine, according to the configuration information, a first transmission parameter corresponding to a first frequency hopping resource in the frequency hopping resources; and the transmission parameters corresponding to other frequency hopping resources have a corresponding relation with the first transmission parameter, and the other frequency hopping resources are frequency hopping resources except the first frequency hopping resource in the frequency hopping resources.

The first information comprises at least one of a first MAsignature, a first MA code word and a first DMRS port corresponding to a first frequency hopping resource in the frequency hopping resources.

For example, the configuration information may include only a first MA signature (or MA codeword) corresponding to the first frequency hopping resource, and the MA signatures (or MA codewords) corresponding to the other frequency hopping resources may be determined according to a correspondence between the MA signatures (or MA codewords) corresponding to the other frequency hopping resources and the first MA signature (or first MA codeword). Or, the configuration information includes only the first DMRS port corresponding to the first frequency hopping resource, the terminal may determine the first MA signature (or the first MA codeword) corresponding to the first frequency hopping resource according to the correspondence between the DMRS port and the MA signature (or the MA codeword), the DMRS ports corresponding to other frequency hopping resources may be determined according to the correspondence between the DMRS ports corresponding to other frequency hopping resources and the first DMRS port, and the MA signatures (or the MA codewords) corresponding to other frequency hopping resources may be determined according to the correspondence between the MA signatures (or the MA codewords) corresponding to other frequency hopping resources and the first MA signature (or the first MA codeword).

In another alternative embodiment, the first information may not include any one of the first MA signature, the first MA codeword, and the first DMRS port, but include other information that can be used to determine any one of the first MA signature, the first MA codeword, and the first DMRS port. That is, the configuration information sent by the base station to the terminal does not explicitly include any MA signature, MA codeword, and DMRS port, and the MA signature (or MA codeword) and/or DMRS port corresponding to each frequency hopping resource of the terminal is determined according to the correspondence between other information in the configuration information and the transmission parameters, so that the signaling overhead of configuration can be reduced.

Specifically, when the transmission parameter includes the MA signature or the MA codeword, a correspondence relationship between the MA signature or the MA codeword corresponding to the other frequency hopping resource and the first MA signature or the first MA codeword is:

MA_signature_mth_hop

(MA _ signature _1st _ hop + offset _ MA _ signature) mod SizeOfMASignation, wherein MA _ signature _ mth _ hop represents an identity (which may also be referred to as an indication or an index) of a MA signature or a MA codeword used by an m-th hopping resource other than a first hopping resource corresponding to the first MA signature or the first MA codeword, MA _ signature _1st _ hop represents an identity of the first MA signature or the first MA codeword, which may be used by a first hopping, or may also be used by other hopping frequencies, SizeOfMASignation represents the number of the MA signatures or MA codewords, mod represents a modulo remainder operation, fset _ MA _ signature represents an identity of the MA signature or MA codeword, the offset _ MA _ signature represents an identity of the MA signature or MA codeword, the M _ signature is determined at least by a position of the m-th hopping resource, and only the frequency domain offset value of the second MA signature or MA codeword is determined by the frequency domain offset of the M-th hopping resource, or may be determined by the frequency domain location of the mth hop resource and other parameters, which may be configured by higher layers or calculated according to other functions.

Further, the following functional relationship exists between the identification offset value of the MA signature or the MA codeword and the frequency domain position of the mth frequency hopping resource:

or,

In addition, when the transmission parameters include the DMRS port, a correspondence between the DMRS port corresponding to the other frequency hopping resource and the first DMRS port is:

DMRS_index_mth_hop

＝(DMRS_index_1st_hop+offset_DMRS_index)mod SizeofDMRS；

wherein DMRS _ index _ mth _ hop denotes an identifier of a DMRS port used by an mth hopping resource among the hopping resources except for a first hopping resource corresponding to the first DMRS port, DMRS _ index _1st _ hop denotes the identifier of the first DMRS port, offset _ DMRS _ index denotes an identifier offset value of the DMRS port, the offset _ DMRS _ index is determined at least by a frequency domain position of the mth hopping resource, sizeoffdmrs denotes the number of the DMRS ports, and mod denotes a remainder operation.

or,

or

offset_DMRS_index＝(f1(RB_Offset)×f2(UE_ID)+offset)mod A；

Preferably, after receiving the correspondence, the terminal may store the correspondence locally, so that the base station does not need to send the correspondence again when configuring the transmission parameters next time, thereby reducing signaling overhead required for configuration.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for determining transmission parameters based on pre-scheduling according to a second embodiment of the present invention, where the method is applied to a terminal and includes the following steps:

step 21: receiving configuration information sent by network side equipment, wherein the configuration information at least comprises information of frequency hopping resources;

step 22: and determining a transmission parameter corresponding to each frequency hopping resource according to the configuration information, wherein the transmission parameter comprises at least one of MA signature, MA code word and DMRS port.

In the embodiment of the invention, the terminal can determine the transmission parameter corresponding to each frequency hopping resource according to the configuration information sent by the network side equipment, and the determination mode of the transmission parameter is clear. In addition, compared with the transmission based on pre-scheduling without adopting a frequency hopping mode, the adoption of the frequency hopping mode can reduce the interfered probability of data transmission, improve the transmission effect and improve the confidentiality of data.

Specifically, the configuration information further includes a frequency hopping pattern adopted by the transmission based on the pre-scheduling: an intra-slot hopping pattern or an inter-slot hopping pattern.

In an optional specific embodiment, the frequency hopping resource includes at least two frequency hopping resources, the configuration information further includes the transmission parameter corresponding to each of the frequency hopping resources, and when the frequency domain positions of the frequency hopping resources are different, the corresponding transmission parameters are different.

For example, if there are two frequency hops in a frequency hopping period, the configuration information includes two MA signatures corresponding to the two frequency hops; if there are four hops in a hop period, the configuration information includes four MA signatures corresponding to the four hops respectively.

In addition, when the frequency domain positions of the frequency hopping resources are different, the corresponding transmission parameters are different, and the problem that the uplink data sent by the terminal cannot be recovered due to the collision of the transmission parameters of a plurality of terminals can be avoided.

Further, in the frequency hopping resources, the frequency hopping resources with the same frequency domain position correspond to the same transmission parameters. For example, if there are four hops in a hop period, and the frequency domain resource occupied by the first hop is the same as the frequency domain resource occupied by the third hop, and the frequency domain resource occupied by the second hop is the same as the frequency domain resource occupied by the fourth hop, the configuration information includes two MA signatures (or MA codewords) or two DMRS ports, where one MA signature (or MA codeword) or DMRS port is used by the first hop and the third hop, and the other MA signature (or MA codeword) or DMRS port is used by the second hop and the fourth hop.

In the embodiment of the invention, the frequency hopping resources with the same frequency domain position correspond to the same transmission parameters, so that the signaling overhead required by configuration can be reduced, and the frequency hopping resources with different frequency domain positions can correspond to different transmission parameters as far as possible.

In the above embodiment, the configuration information sent by the base station for configuring the transmission parameters based on the pre-scheduling explicitly includes all the transmission parameters used by the terminal, and the configuration method is simple and direct, but the signaling overhead required for configuration is large.
