In a non-terrestrial network (NTN) scenario, a cell is composed of multiple beams (beams), as shown in fig. 2. In the NTN, the satellite operates on a specific orbit, and its motion is regular, so that the propagation delay variation caused by the satellite motion is regular and predictable. Due to the fast movement of the satellite, user Equipment (UE) needs to perform beam switching frequently. At present, terrestrial network protocols, such as narrowband Band Internet of Things (NB-IOT) and enhanced machine communication (LTE enhanced MTO, eMTC), do not support a beam management mechanism, and therefore a set of beam management mechanism is required for future devices to access through a satellite network.

In the current protocol, in order to ensure the coverage, NB-IOT and eMTC employ a repeat transmission technique, where the maximum number of repetitions is 2048 for downlink transmission and 128 for uplink transmission. Due to the repeated transmission, one data scheduling needs to last for a long time.

In this case, due to the fast movement of the beam in the NTN scenario, the UE may receive the beam for DCI, the beam for PDSCH, and the beam for transmitting HARQ-ACK on different transmission resources. Therefore, how to determine the transmission resources of the uplink and downlink data by the UE in the data scheduling process is a technical problem to be solved urgently at present.

In order to solve the above problem, the present application provides a transmission resource indication method, which indicates a transmission resource for uplink and downlink data transmission of a terminal device by sending an indication message to the terminal device, so as to solve the problem that the uplink and downlink transmission resources of the terminal device are different in a data scheduling process.

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

In this application, the network device may determine, through the location of the terminal device, the beam distribution condition in the cell, and the ephemeris information, a plurality of candidate downlink transmission resources and a plurality of candidate uplink transmission resources associated with each downlink transmission resource in the cell or each downlink transmission resource in a part of the cell. The network device indicates the candidate downlink transmission resources and the candidate uplink transmission resources which can be used by the network device to the terminal device, so that the resource scheduling of the data transmission of the terminal device can be realized.

For example, the network device may determine, through the location of the terminal device, the beam distribution condition in the cell, and the ephemeris information, a plurality of candidate beams associated with each beam in the cell or each beam in beams in the cell, and a candidate uplink transmission resource and a candidate downlink transmission resource associated with each candidate beam.

In some embodiments, the ephemeris information may include information about the satellite's motion trajectory, such as satellite orbit, satellite coordinates, satellite velocity, and the like. For example, the ephemeris information may be described using Kepler six parameters including semi-major axis, eccentricity, orbital inclination, ascension/descent at ascension point, amplitude angle at sunrise point, mean and apoint angle for a specified epoch. The semimajor axis is half of the major axis of the elliptical orbit and can be sometimes regarded as the average orbit radius, the eccentricity is the ratio of the distance between two focuses of the elliptical orbit and the length of the major axis, and is a measure of the flatness of the elliptical orbit, the inclination angle of the orbit is the inclination angle of the plane of the planetary orbit and the plane of the ecliptic, the right ascension/yellow ascension of the rising intersection point is the longitude of the rising intersection point of the planetary orbit, the argument of the near-day point is the angle from the rising intersection point to the near-day point along the counterclockwise moving orbit, the angle of the mean-near point of the designated epoch is the moving angle of the object on the orbit relative to the central point on the auxiliary circle in the orbital mechanics, and the relationship between the mean-near point angle and the time is linear.

In the application, the network device determines, according to the user location, the beam distribution condition in the cell, and the ephemeris information, the transmission resources for the terminal device to receive the DCI beam, receive the PDSCH beam, and send the HARQ-ACK, and instructs the device to configure the uplink and downlink transmission resource indexes for data transmission between the terminal device and the satellite, thereby solving the problem of different uplink and downlink transmission resources in the data scheduling process.

Optionally, each candidate downlink transmission resource is associated with an uplink transmission resource.

In some embodiments, the network device may further determine, according to the location of the terminal device, the beam distribution condition in the cell, and the ephemeris information, one uplink transmission resource associated with each candidate downlink transmission resource. The network device can enable the terminal device to determine the uplink transmission resource for HARQ-ACK transmission according to the uplink transmission resource associated with the candidate downlink transmission resource by indicating the candidate downlink transmission resource of the terminal device.

Optionally, the method further includes: the network device sends a second message to the terminal device, where the second message includes the candidate downlink transmission resources and the candidate uplink transmission resources associated with each transmission resource in the first transmission resource set.

In some embodiments, the second message is an RRC message or a system broadcast message.

Specifically, the network device configures, to the terminal device, multiple candidate downlink transmission resources associated with each downlink transmission Resource in a cell or each downlink transmission Resource in the downlink transmission resources in the cell and multiple candidate uplink transmission Resource information through RRC signaling or system broadcast message, or the network device may also configure, to the terminal device, multiple candidate beam information associated with each beam in the cell or each beam in the beams in the cell through Radio Resource Control (RRC) signaling.

For example, the network device configures, through system broadcast information, multiple candidate downlink transmission resources and multiple candidate uplink transmission resource information associated with each downlink transmission resource in the cell to the terminal device, or the network device configures, through system broadcast information, multiple candidate beam information associated with each beam in the cell to the terminal device.

In the application, the network device can flexibly configure the candidate transmission resources of the terminal device by sending the transmission resource information determined according to the position of the terminal device, the beam distribution condition in the cell and the ephemeris information to the terminal device, thereby realizing flexible scheduling of the downlink transmission resources.

In an example, the second message further includes an uplink transmission resource associated with each of the candidate downlink transmission resources. And sending one uplink transmission resource associated with each candidate downlink transmission resource to the terminal equipment, so that the terminal equipment can determine the uplink transmission resource for HARQ-ACK transmission according to the uplink transmission resource associated with the candidate downlink transmission resource.

And S320, the terminal equipment receives the first indication message and transmits data according to the transmission resource index.

In some embodiments, after receiving the first indication message, the terminal device receives downlink data in the downlink transmission resource indicated in the first indication message (i.e. PDSCH reception), and transmits uplink data in the uplink transmission resource indicated in the first indication message (PUSCH, PUCCH, or HARQ-ACK transmission).

Optionally, the method further includes: the terminal device receives a second message, where the second message includes multiple candidate downlink transmission resources and multiple candidate uplink transmission resources associated with each transmission resource in a first transmission resource set, the first transmission resource set is a set of all or part of downlink transmission resources in a target cell, and the target cell is a current serving cell of the terminal device.

Specifically, the terminal device receives candidate transmission resource information configured by the network device. When the first indication message indicates the candidate uplink transmission resource index and the candidate downlink transmission resource index, the terminal device may determine, according to the candidate transmission resource information and the first indication message, a candidate downlink transmission resource for the terminal device to perform downlink data reception and a candidate uplink transmission resource for performing uplink data transmission this time.

For example, the second message further includes one uplink transmission resource associated with each of the candidate downlink transmission resources.

In some embodiments, when the first indication information only indicates a candidate downlink transmission resource index, the terminal device may perform downlink data reception on the candidate downlink transmission resource and perform uplink data transmission in an uplink transmission resource associated with the candidate downlink transmission resource.

It can be seen that, the present application provides a transmission resource indication method, in which a terminal device receives a first indication message sent by a network device, where the first indication message is used to indicate a transmission resource index of data transmission, and the data transmission is data transmission between the terminal device and a satellite; the terminal equipment transmits data according to the transmission resource index, and the problem that the uplink and downlink transmission resources of the terminal equipment are different in the data scheduling process can be solved by sending the indication message to the terminal equipment to indicate the uplink and downlink transmission resources of the terminal equipment.

Referring to fig. 4, fig. 4 is a flowchart illustrating another method for indicating transmission resources according to an embodiment of the present application, which is applied to the wireless communication system shown in fig. 1. As shown in fig. 4, the method includes the following steps.

S410, the network equipment sends a first indication message to the terminal equipment, wherein the first indication message is used for indicating a transmission resource index of data transmission, the data transmission is data transmission between the terminal equipment and a satellite, the first indication message comprises transmission resource indication information and an uplink or downlink transmission resource index, and the transmission resource indication information is used for indicating that the first indication message comprises the uplink or downlink transmission resource index.

The terminal equipment needs to receive DCI before receiving downlink data (PDSCH receiving) sent by the network equipment, determines the receiving position of the PDSCH according to the indication in the DCI, and determines the resource position fed back by the HARQ-ACK according to the HARQ-ACK related indication information in the DCI. Therefore, the method and the device can solve the problem of different uplink and downlink transmission resources in the data scheduling process and save resource overhead by directly indicating the transmission resource index of the data transmission of the terminal equipment in the DCI.

Optionally, the transmission resource is any one of the following: carrier, fractional bandwidth BWP, narrowband.

In some embodiments, a cell is composed of multiple beams, different beams may correspond to different carriers, partial Bandwidths (BWPs) or narrowbands, and the network device performs beam switching by switching carriers, BWPs or narrowbands when the terminal device needs to perform beam switching frequently by indicating the indexes of the carriers, BWPs or narrowbands corresponding to data transmission by the terminal device.

Specifically, the network device configures, to the terminal device, multiple candidate downlink transmission resources associated with each downlink transmission resource in a cell or each downlink transmission resource in a part of downlink transmission resources in the cell and multiple candidate uplink transmission resource information through RRC signaling or a system broadcast message, or the network device may also configure, to the terminal device, multiple candidate beam information associated with each beam in a cell or each beam in a part of beams in the cell through RRC signaling.

Optionally, the first indication message includes a first bit field and a second bit field, where the first bit field is used to indicate the uplink or downlink transmission resource index, and the second bit field is used to indicate the transmission resource indication information.

In the embodiment of the present application, two bit fields, namely, a first bit field and a second bit field, are introduced into a downlink scheduling DCI message, where the first bit field is used to indicate the uplink or downlink transmission resource index, and the second bit field is used to indicate whether the first bit field indicates the downlink transmission resource index or the uplink transmission resource index.

In some embodiments, the number of bits of the second bit field may be 1, and the first value and the second value may be 1 or 0; when the second value is 0, the first value is 1.

Specifically, if the value of the second bit field is 1, the first bit field is used to indicate the downlink transmission resource index, and if the value of the second bit field is 0, the first bit field is used to indicate the uplink transmission resource index. Or if the second bit field value is 0, the first bit field is used for indicating the downlink transmission resource index, and if the second bit field value is 1, the first bit field is used for indicating the uplink transmission resource index.

Optionally, the method further includes: the network device determines the bit number of the first bit field according to the number of the candidate downlink transmission resources or the candidate uplink transmission resources associated with each transmission resource in the first transmission resource set.

In this embodiment, the network device may determine the number of bits in the first bit field according to the number of multiple candidate downlink transmission resources associated with each downlink carrier in each downlink transmission resource or part of downlink transmission resources in the cell and the number of multiple candidate uplink transmission resources, or the network device determines the number of bits in the first bit field in the scheduling DCI according to the number of candidate beams associated with each beam in the cell or part of beams in the cell.

In some embodiments, the first bit field is used to indicate an uplink or downlink transmission resource index, and therefore, when the first bit field indicates a downlink transmission resource index, the network device may determine the number of bits of the first bit field according to the number of the candidate downlink transmission resources associated with each transmission resource in the first transmission resource set configured in the second message; when the first bit field indicates the uplink transmission resource index, the network device may determine the bit number of the first bit field according to the number of the multiple candidate uplink transmission resources associated with each transmission resource in the first transmission resource set configured in the second message.

For example, the first bit field may be represented by M bit code words, that is, the number of bits of the first bit field is M, and M is a positive integer greater than 1. The M bit code words are in one-to-one correspondence with the candidate downlink transmission resources or the candidate uplink transmission resources, that is, each bit code word represents one candidate downlink transmission resource or one candidate uplink transmission resource. If the bit code word is 1, it indicates that the candidate downlink transmission resource or the candidate uplink transmission resource corresponding to the bit code word is an available resource, or if the bit code word is 0, it indicates that the candidate downlink transmission resource or the candidate uplink transmission resource corresponding to the bit code word is an available resource. For example, assuming that the current serving cell includes 3 candidate uplink transmission resources (RE _ up1, RE _ up2, RE _ up 3) and 4 candidate downlink transmission resources (RE _ down1, RE _ down 2, RE _ down 3, RE _ down 4), when the second bit field value is 1, it indicates that the first bit field indicates a downlink transmission resource index, the first bit field is 4 bits, each bit corresponds to one candidate downlink transmission resource, if the first bit field value is 0100, it indicates that RE _ down 3 is a downlink available resource, and if the first bit field value is 1000, it indicates that RE _ down 4 is a downlink available resource; if the first bit field value is 0001, it indicates that RE _ down1 is a downlink available resource. When the value of the second bit field is 0 and the first bit field indicates that the first bit field indicates the uplink transmission resource index, the first bit field is 3 bits, each bit corresponds to a candidate uplink transmission resource, and if the value of the first bit field is 100, the RE _ up3 is an uplink available resource; if the first bit field value is 010, it indicates that RE _ up2 is an uplink available resource; if the first bit field value is 001, it indicates that RE _ up1 is an uplink available resource.

For example, to save bit overhead, the first bit field may be represented by K bit code words, i.e. the number of bits of the first bit field is K, K is a positive integer,

indicating rounding up, when M is 3 or 4, K is 2, when M is 5 to 8, K is 3, when M is 9 to 16, K is 4, and the like, M is a candidate downlink transmission resource or a candidate uplink transmission resourceThe amount of resources to be transferred. For example, assuming that the current serving cell includes 3 candidate uplink transmission resources (RE _ up1, RE _ up2, RE _ up 3) and 5 candidate downlink transmission resources (RE _ down1, RE _ down 2, RE _ down 3, RE _ down 4, RE _ down 5), when the second bit field value is 1, it indicates that the first bit field indicates a downlink transmission resource index, the first bit field is 3 bits, and if the first bit field value is 010, it indicates that RE _ down 3 is a downlink available resource; if the first bit field value is 000, the RE _ down1 is the downlink available resource; if the first bit field value is 001, the RE _ down 2 is the downlink available resource; if the first bit field value is 011, the RE _ down 4 is a downlink available resource; if the first bit field value is 100, it indicates that RE _ down 5 is a downlink available resource. When the value of the second bit field is 0, the first bit field indicates that the first bit field indicates the uplink transmission resource index, the first bit field is 2 bits, and if the value of the first bit field is 10, the RE _ up3 is the uplink available resource; if the first bit field value is 00, the RE _ up1 is the uplink available resource; if the first bit field value is 01, it indicates that RE _ up2 is an uplink available resource.

It should be noted that other ways of determining the bit number of the first bit field according to the number of the candidate uplink transmission resources or the candidate downlink transmission resources may also be applicable to the present application, and the embodiment of the present application is not limited thereto.

S420, the terminal equipment receives the first indication message and transmits data according to the transmission resource index.

Specifically, the terminal device receives candidate transmission resource information configured by the network device. When the first indication message indicates the candidate uplink transmission resource index and the candidate downlink transmission resource index, the terminal device may determine, according to the candidate transmission resource information and the first indication message, the candidate downlink transmission resource for the terminal device to perform downlink data reception and the candidate uplink transmission resource for performing uplink data transmission this time.

In an example, the second message further includes an uplink transmission resource associated with each of the candidate downlink transmission resources.

Optionally, the method further includes: the terminal device determines the bit number of the first bit field according to the number of the candidate downlink transmission resources or the candidate uplink transmission resources associated with each transmission resource in the first transmission resource set.

In this embodiment, after receiving the first indication message, the terminal device determines whether the first bit field indicates a downlink transmission resource index or an uplink transmission resource index according to a value of the second bit field. And when the first bit field indicates the downlink transmission resource index, the terminal equipment determines the bit number of the first bit field according to the number of the candidate downlink transmission resources in the second message, and further determines the target downlink transmission resource according to the value of the first bit field. And when the first bit field indicates the uplink transmission resource index, the terminal equipment determines the bit number of the first bit field according to the number of the candidate uplink transmission resources in the second message, and further determines the target uplink transmission resource according to the value of the first bit field.

Optionally, the method further includes: and the terminal equipment determines a target downlink transmission resource and a target uplink transmission resource according to the first bit field value and the second bit field value.

In this embodiment, the terminal device determines, according to a value of a second bit field in the DCI, whether the first bit field indicates the uplink transmission resource index or is used to indicate the downlink transmission resource index. For example, when the value of the second bit field is 1, it indicates that the first bit field is used to indicate one downlink transmission resource (i.e. PDSCH receiving carrier) in the multiple downlink candidate transmission resources as the target downlink transmission resource, and otherwise, the first bit field is used to indicate one uplink transmission resource in the multiple candidate uplink transmission resources as the target uplink transmission resource.

In some embodiments, the determining, by the terminal device, a target downlink transmission resource and a target uplink transmission resource according to the values of the first bit field and the second bit field includes: when the second bit field value is the first value, the terminal device determines the candidate downlink transmission resource corresponding to the first bit field value as the target downlink transmission resource, and determines the uplink transmission resource associated with the target downlink transmission resource as the target uplink transmission resource; and when the second bit field value is the second value, the terminal device determines the candidate uplink transmission resource corresponding to the first bit field value as the target uplink transmission resource, and determines a first transmission resource as the target downlink transmission resource, where the first transmission resource is a transmission resource for bearing the first indication message.

Specifically, in the data scheduling process, the terminal device determines, according to a value of a second bit field in the DCI, whether the first bit field indicates the uplink transmission resource index or the downlink transmission resource index. The method specifically comprises the following steps: when the second bit field value is 1, which indicates that the first bit field is used to indicate the candidate downlink transmission resource index, the terminal device takes the downlink candidate transmission resource corresponding to the first bit field value as a target downlink transmission resource (i.e., PDSCH receiving resource), and determines the uplink transmission resource associated with the downlink candidate transmission resource corresponding to the first bit field value as a target uplink transmission resource (i.e., PUSCH, PUCCH, or HARQ-ACK transmitting resource). As shown in FIG. 4a, the PDSCU receive beam and the HARQ-ACK transmit beam are both beam1 or beam2.

The first bit field is used for indicating one uplink carrier in the plurality of candidate uplink carriers as a target uplink carrier. When the value of the second bit field is 0, which indicates that the first bit field is used to indicate the candidate uplink transmission resource index, the terminal device takes the uplink candidate transmission resource corresponding to the value of the first bit field as a target uplink transmission resource (i.e. a PUSCH, PUCCH or HARQ-ACK transmission resource), and takes the downlink transmission resource receiving the DCI message as a target downlink transmission resource (i.e. a PDSCH receiving resource), i.e. receives the PDSCH on the resource receiving the DCI. As shown in fig. 4b, the PDSCH receiving beam and the DCI receiving beam are beam1, and the HARQ-ACK transmitting beam is beam2.

It can be seen that, the present application provides a transmission resource indication method, where a terminal device receives a first indication message sent by a network device, and indicates, through a second bit field, whether a first bit field indicates an uplink transmission resource index or an indication or a downlink transmission resource index, so as to solve the problem that uplink and downlink transmission resources of the terminal device are different in a data scheduling process, and save bit overhead.

Referring to fig. 5, fig. 5 is a flowchart illustrating another method for indicating transmission resources according to an embodiment of the present application, which is applied to the wireless communication system shown in fig. 1. As shown in fig. 5, the method includes the following steps.

S510, a network device sends a first indication message to a terminal device, wherein the first indication message is used for indicating a transmission resource index of data transmission, the data transmission is data transmission between the terminal device and a satellite, and the first indication message comprises an uplink transmission resource index and a downlink transmission resource index.

In some embodiments, the first indication message is downlink control information DCI. The terminal equipment needs to receive DCI before receiving downlink data (PDSCH receiving) sent by the network equipment, determines the receiving position of the PDSCH according to the indication in the DCI, and determines the resource position fed back by the HARQ-ACK according to the HARQ-ACK related indication information in the DCI. Therefore, the method and the device can solve the problem of different uplink and downlink transmission resources in the data scheduling process and save the resource overhead by directly indicating the transmission resource index of the data transmission of the terminal equipment in the DCI.

In some embodiments, a cell is composed of multiple beams, different beams may correspond to different carriers, partial Bandwidths (BWPs) or narrowbands, and the network device performs beam switching by switching carriers, BWPs or narrowbands when the terminal device needs to perform beam switching frequently by indicating the indexes of the carriers, BWPs or narrowbands for data transmission of the terminal device.

Optionally, the method further includes: the network device determines, according to first information, a first transmission resource set, and a plurality of candidate downlink transmission resources and a plurality of candidate uplink transmission resources associated with each transmission resource in the first transmission resource set, where the first transmission resource set is a set of all or part of downlink transmission resources in a target cell, the target cell is a current serving cell of the terminal device, and the first information includes at least one of: ephemeris information, beam distribution of the target cell, and a location of the terminal device.

In the application, the network device determines, through the position of the terminal device, the beam distribution condition in the cell, and the ephemeris information, that the terminal device receives the DCI and the PDSCH and transmits the HARQ-ACK transmission resource index, and configures the uplink and downlink transmission resource indexes for data transmission between the terminal device and the satellite for the terminal device, thereby solving the problem of different uplink and downlink transmission resources in the data scheduling process.

Optionally, the method further includes: and the network equipment sends a second message to the terminal equipment, wherein the second message comprises the candidate downlink transmission resources and the candidate uplink transmission resources associated with each transmission resource in the first transmission resource set.

Optionally, the first indication message includes a third bit field and a fourth bit field, where the third bit field is used to indicate the downlink transmission resource index, and the fourth bit field is used to indicate the uplink transmission resource index.

In the implementation of the present application, two bit fields, namely a third bit field and a fourth bit field, are introduced into a downlink scheduling DCI, where the third bit field is used to indicate a downlink transmission resource index, and the fourth bit field is used to indicate an uplink transmission resource index. The network device can flexibly configure uplink and downlink transmission resources of the terminal device by setting values of the third bit field and the fourth bit field.

Optionally, the method further includes: the network device determines the bit number of the third bit field according to the number of the candidate downlink transmission resources associated with each transmission resource in the first transmission resource set, and determines the bit number of the fourth bit field according to the number of the candidate uplink transmission resources associated with each transmission resource in the first transmission resource set.

In this embodiment, the network device may determine the number of bits associated with the third bit field and the fourth bit field respectively according to the number of multiple candidate downlink transmission resources associated with each downlink carrier in each downlink transmission resource or part of downlink transmission resources in the cell and the number of multiple candidate uplink transmission resources, or the network device determines the number of bits of the third bit field and the fourth bit field in the scheduling DCI according to the number of candidate beams associated with each beam in each beam or part of beams in the cell.

In some embodiments, the third bit field is used to indicate a downlink transmission resource index, and the fourth bit field is used to indicate an uplink transmission resource index. Therefore, the network device may determine the bit number of the third bit field according to the number of the candidate downlink transmission resources configured in the second message, and determine the bit number of the fourth bit field according to the number of the candidate uplink transmission resources configured in the second message.

Illustratively, the third bit field may be represented by M bit code words, i.e. the number of bits of the third bit field is M; the fourth bit field can be represented by N bit code words, i.e. the number of bits of the fourth bit field is N, and both N and M are positive integers greater than 1. The M bit code words correspond to candidate downlink transmission resources one to one, and the N bit code words correspond to candidate uplink transmission resources one to one. If the bit code word is 1, it indicates that the candidate downlink transmission resource or the candidate uplink transmission resource corresponding to the bit code word is an available resource, or if the bit code word is 0, it indicates that the candidate downlink transmission resource or the candidate uplink transmission resource corresponding to the bit code word is an available resource. For example, if the current serving cell includes 3 candidate uplink transmission resources (RE _ up1, RE _ up2, RE _ up 3) and 4 candidate downlink transmission resources (RE _ down1, RE _ down 2, RE _ down 3, RE _ down 4), the third bit field is 4 bits, each bit corresponds to one candidate downlink transmission resource, and if the first bit field is 0100, RE _ down 3 is indicated as a downlink available resource; if the first bit field value is 0010, the RE _ down 2 is a downlink available resource; if the first bit field value is 1000, it indicates that RE _ down 4 is a downlink available resource. The fourth bit field is 3 bits, each bit corresponds to a candidate uplink transmission resource, and if the value of the first bit field is 010, the RE _ up2 is an uplink available resource; if the first bit field value is 001, the RE _ up1 is the uplink available resource; if the first bit field value is 100, it indicates that RE _ up3 is an uplink available resource.

To save bit overhead, the third bit field may be represented by a K-bit code word, i.e. the number of bits of the third bit field is K,

the fourth bit field can be represented by an L-bit code word, i.e. the third bit field has a number of bits L,

wherein L and K are both positive integers,

and the number of the candidate downlink transmission resources is represented by rounding up, M is the number of the candidate downlink transmission resources, and N is the number of the candidate uplink transmission resources. For example, if the current serving cell includes 3 candidate uplink transmission resources (RE _ up1, RE _ up2, RE _ up 3) and 5 candidate downlink transmission resources (RE _ down1, RE _ down 2, RE _ down 3, RE _ down 4, RE _ down 5), the first bit field is 3 bits, and if the value of the first bit field is 010, it indicates that RE _ down 3 is a downlink available resource; if the first bit field value is 000, the RE _ down1 is a downlink available resource; if the first bit field value is 001, the RE _ down 2 is the downlink available resource; if the first bit field value is 011, the RE _ down 4 is a downlink available resource; if the first bit field value is 100, it indicates that RE _ down 5 is a downlink available resource. The fourth bit field is 2 bits, if the value of the fourth bit field is 10, the RE _ up3 is the uplink available resource; if the value of the fourth bit field is 01, the RE _ up2 is the uplink available resource; if the value of the fourth bit field is 00, it indicates that RE _ up1 is an uplink available resource.

It should be noted that other manners of determining the bit number of the fourth bit field according to the candidate uplink transmission resources and determining the bit number of the third bit field according to the number of the candidate downlink transmission resources may also be applicable to the present application, and the comparison in the embodiment of the present application is not limited.

S520, the terminal equipment receives the first indication message and transmits data according to the transmission resource index.

In some embodiments, after receiving the first indication message, the terminal device performs downlink data reception (i.e. PDSCH reception) in the downlink transmission resources indicated in the first indication message, and performs uplink data transmission (PUSCH, PUCCH, or HARQ-ACK transmission) in the uplink transmission resources indicated in the first indication message.

Optionally, the method further includes: the terminal device determines the bit number of the third bit field according to the number of the candidate downlink transmission resources associated with each transmission resource in the first transmission resource set, and determines the bit number of the fourth bit field according to the number of the candidate uplink transmission resources associated with each transmission resource in the first transmission resource set.

In the embodiment of the application, after the terminal device receives the first indication message, the terminal device determines the bit number of a third bit field according to the number of the candidate downlink transmission resources in the second message, and further determines the target downlink transmission resources according to the value of the third bit field; and the terminal equipment determines the bit number of a fourth bit field according to the number of the candidate uplink transmission resources in the second message, and further determines the target uplink transmission resources according to the value of the fourth bit field.

Optionally, the terminal device determines the candidate downlink transmission resource corresponding to the third bit field value as a target downlink transmission resource; and the terminal equipment determines the candidate uplink transmission resource corresponding to the fourth bit field value as a target uplink transmission resource.

Specifically, the terminal device determines the downlink transmission resource or beam where the PDSCH is located according to the value of the third bit field in the DCI, and determines the uplink transmission resource or beam where the PUSCH, PUCCH, or HARQ-ACK is sent according to the value of the fourth bit field in the DCI.

It can be seen that, in the method for indicating transmission resources provided by the present application, the terminal device receives a first indication message sent by the network device, and indicates, through a third bit field in the first indication message, a downlink transmission resource index for data transmission and indicates, through a fourth bit field in the first indication message, an uplink transmission resource index for data transmission, thereby solving the problem that uplink and downlink transmission resources of the terminal device are different in a data scheduling process.
