[0003] With the development of communication technology, the number of terminal devices is rapidly increasing, and system capacity is an important indicator for communication system design. The most direct way to improve system capacity is to increase the multiplexing dimension of physical resources. Common resource multiplexing methods include time domain multiplexing, frequency domain multiplexing, and code domain multiplexing. Among them, code domain multiplexing technology can be used to realize data transmission of multiple terminal devices in the same time-frequency resource, wherein the OCC (Orthogonal Cover Code) used by different terminal devices for data transmission is different. For OCC multiplexing, how terminal devices determine OCC information is a problem to be solved by the present application. SUMMARY

It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new service scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0100] The OCC information indication method provided in the present application is described below.

[0101] Please refer to FIG. 2, which is a flowchart of an OCC information indication method provided in an embodiment of the present application. As shown in FIG. 2, the OCC information indication method can include but is not limited to the following steps.

[0102] S201: The network device sends DCI, the DCI is used for scheduling first data, the DCI includes first indication information, the first indication information is used for determining OCC information corresponding to a first OCC scheme group, the first OCC scheme group includes two OCC schemes in intra symbol OCC multiplexing, inter symbol OCC multiplexing and inter slot OCC multiplexing. Correspondingly, the terminal device receives the DCI from the network device.

[0103] The first OCC scheme group can include at least two OCC schemes in intra symbol OCC multiplexing, inter symbol OCC multiplexing and inter slot OCC multiplexing, that is, the first OCC scheme group is obtained by combining at least two OCC schemes in intra symbol OCC multiplexing, inter symbol OCC multiplexing and inter slot OCC multiplexing. The OCC multiplexing in the manner of combining multiple OCC schemes can improve system capacity.

[0104] For example, the OCC scheme group can include: a scheme group obtained by combining two OCC schemes in intra symbol OCC multiplexing and inter symbol OCC multiplexing, a scheme group obtained by combining two OCC schemes in intra symbol OCC multiplexing and time OCC multiplexing, a scheme group obtained by combining two OCC schemes in inter symbol OCC multiplexing and inter slot OCC multiplexing, and a scheme group obtained by combining three OCC schemes in intra symbol OCC multiplexing, inter symbol OCC multiplexing and inter slot OCC multiplexing. The first OCC scheme group can be any one of these scheme groups. The embodiments of the present application take the first OCC scheme group including two OCC schemes in intra symbol OCC multiplexing, inter symbol OCC multiplexing and inter slot OCC multiplexing as an example for description.

[0105] The intra symbol OCC multiplexing scheme refers to that data transmission is in the frequency domain, and each RE or RB is expanded to M REs or RBs for transmission by OCC, and the value of M is equal to the code length of OCC. The inter symbol OCC multiplexing scheme refers to that data transmission is in the time domain, and each symbol is expanded to M symbols for transmission by OCC, and the value of M is equal to the code length of OCC. The inter slot OCC multiplexing scheme refers to that data transmission is in the time domain, and each slot is expanded to M slots for data transmission by OCC, and the value of M is equal to the code length of OCC.

[0106] Optionally, the OCC scheme can also be divided into a time domain OCC scheme and a frequency domain OCC scheme. The time domain OCC scheme refers to spreading data transmission in the time domain by using OCC, that is, spreading data in each time unit in the time domain to M time units by using OCC for transmission. The time unit can be a time slot, a symbol, a subframe, or a time unit of other granularity. The value of M is equal to the code length of the OCC. The time domain OCC scheme can include an inter-symbol OCC multiplexing scheme and an inter-time slot OCC multiplexing scheme. The frequency domain OCC scheme refers to spreading data transmission in the frequency domain by using OCC, that is, spreading data in each frequency domain unit in the frequency domain to M frequency domain units by using OCC for transmission. The frequency domain unit can be a RE, an RB, or a frequency domain unit of other granularity. The value of M is equal to the code length of the OCC. The frequency domain OCC scheme can include an intra-symbol OCC multiplexing scheme.

[0107] Optionally, the first OCC scheme group includes at least one time domain OCC scheme and one frequency domain OCC scheme. Taking the first OCC scheme group including one time domain OCC scheme and one frequency domain OCC scheme as an example, the first OCC scheme group includes two OCC schemes, that is, an intra-symbol OCC multiplexing scheme and an inter-symbol OCC multiplexing scheme. For another example, the first OCC scheme group includes two OCC schemes, that is, an intra-symbol OCC multiplexing scheme and an inter-time slot OCC multiplexing scheme.

[0108] Each OCC scheme in the first OCC scheme group corresponds to respective OCC information. In the embodiments of the present application, taking the first OCC scheme group including two OCC schemes, and the two OCC schemes being a first OCC scheme and a second OCC scheme as an example, that is, the first OCC scheme and the second OCC scheme are different OCC schemes in an intra-symbol OCC multiplexing scheme, an inter-symbol OCC multiplexing scheme, and an inter-time slot OCC multiplexing scheme. The OCC information corresponding to the first OCC scheme group can include first OCC information and second OCC information. The first OCC information is the OCC information corresponding to the first OCC scheme, and the second OCC information is the OCC information corresponding to the second OCC scheme.

[0109] The OCC information can include one or more of the following: an OCC, an index of the OCC, a code length of the OCC, and the like. The OCC can also be referred to as an OCC code or an OCC sequence. For example, taking the code element value of the OCC as +1 or -1 as an example, assuming that the code length of the OCC is 2, the OCC can be [+1, -1], [+1, +1], and the like. Assuming that the code length of the OCC is 4, the OCC can be [+1, -1, -1, -1], [+1, +1, -1, -1], [+1, +1, +1, -1], and the like.

[0110] Taking the first OCC scheme as intra-symbol OCC multiplexing, the second OCC scheme as inter-symbol OCC multiplexing, the OCC information corresponding to the first OCC scheme as OCC1, the code length of OCC1 as 4, and the OCC information corresponding to the second OCC scheme as OCC2, and the code length of OCC2 as 5 as an example, the first OCC scheme group is represented as: the sender transmits data on each RE or RB by expanding the data on each RE or RB to 4 REs or RBs through OCC1 in the frequency domain, and expands the data on each symbol to 5 symbols through OCC2 in the time domain.

[0111] The first data scheduled by the DCI can be uplink data or downlink data.

[0112] It should be noted that the OCC scheme can also be described as an OCC multiplexing scheme, OCC multiplexing, or other names, and other names used to describe the essence of the OCC scheme can be replaced with the OCC scheme. Intra-symbol OCC multiplexing can also be described as intra-symbol OCC or other names, and other names used to describe the essence of intra-symbol OCC multiplexing can be replaced with intra-symbol OCC multiplexing. Inter-symbol OCC multiplexing can also be described as inter-symbol OCC or other names, and other names used to describe the essence of inter-symbol OCC multiplexing can be replaced with inter-symbol OCC multiplexing. Inter-slot OCC multiplexing can also be described as inter-slot OCC or other names, and other names used to describe the essence of inter-slot OCC multiplexing can be replaced with inter-slot OCC multiplexing.

[0113] S202: The terminal device determines OCC information corresponding to the first data based on the first indication information, and the OCC information corresponding to the first data is OCC information corresponding to the first OCC scheme group.

[0114] After receiving the DCI, the terminal device can determine the OCC information corresponding to the first data based on the first indication information, and the OCC information corresponding to the first data is the OCC information corresponding to the first OCC scheme group.

[0115] It can be understood that when the first data is uplink data, the terminal device can expand the uplink data on each resource unit to M resource units through the OCC information corresponding to the first OCC scheme group for transmission. Correspondingly, after receiving the data from the terminal device, the network device can de-expand the data on the M resource units received through the OCC information corresponding to the first OCC scheme group to restore the original uplink data, where M is the code length of the OCC in the OCC information.

[0116] In a case that the first data is downlink data, the network device can spread the downlink data on each resource unit to M resource units through the OCC information corresponding to the first OCC scheme group for transmission. Correspondingly, after receiving the data from the network device, the terminal device can despread the data on the M resource units through the OCC information corresponding to the first OCC scheme group to restore the original downlink data, where M is the code length of the OCC in the OCC information.

[0117] The resource unit can include a time unit and / or a frequency domain unit. For example, in a case that the first OCC scheme group includes at least a time domain OCC scheme, the resource unit includes at least a time unit. In a case that the first OCC scheme group includes at least a frequency domain OCC scheme, the resource unit includes at least a frequency domain unit.

[0118] In the embodiments of the present application, the first indication information in the DCI can be used to determine the OCC information corresponding to the first OCC scheme group, and the OCC information is the OCC information corresponding to the first data scheduled by the DCI. In this way, two OCC schemes can be combined for OCC multiplexing, thereby facilitating the improvement of system capacity.

[0119] Next, the bit field design of the DCI is introduced, so that the first indication information in the DCI can be used to determine the OCC information corresponding to the first OCC scheme group.

[0120] One possible implementation of the bit field design of the DCI (hereinafter referred to as DCI bit field design method 1): taking a case that the first OCC scheme group includes M OCC schemes of intra-symbol OCC multiplexing, inter-symbol OCC multiplexing, and inter-slot OCC multiplexing as an example, the first indication information is carried by M bit fields in the DCI, and one bit field in the M bit fields carries the OCC information or the index of the OCC information corresponding to one of the M OCC schemes. M is an integer greater than 1. In other words, the OCC information or the index of the OCC information corresponding to different OCC schemes in the first OCC scheme group is carried by different bit fields in the DCI. In this way, the OCC information corresponding to different OCC schemes in the first OCC scheme group can be quickly determined.

[0121] Taking a case that M=2 and the two OCC schemes included in the first OCC scheme group are a first OCC scheme and a second OCC scheme as an example, the DCI includes at least a first bit field and a second bit field, and the first indication information is carried by the first bit field and the second bit field. The first bit field carries the first OCC information or the index of the first OCC information, and the second bit field carries the second OCC information or the index of the second OCC information. The first OCC information is the OCC information corresponding to the first OCC scheme, and the second OCC information is the OCC information corresponding to the second OCC scheme.

[0122] DCI bit field design manner 1 can also be understood as: the DCI at least includes an OCC information indication field for carrying the first indication information, and the OCC information indication field includes M bit fields.

[0123] For example, in the case of M=2, a schematic diagram of the OCC information indication field can be as shown in FIG. 3. In FIG. 3, a black box represents a bit field. As shown in FIG. 3, the OCC information indication field includes two bit fields, which are a first bit field and a second bit field respectively, wherein the first bit field carries the first OCC information or the index of the first OCC information, and the second bit field carries the second OCC information or the index of the second OCC information.

[0124] The present embodiment does not limit the number of bits occupied by each bit field in the M bit fields, and the number of bits occupied by different bit fields in the M bit fields can be the same; or the number of bits occupied by part of the bit fields in the M bit fields is the same, and the number of bits occupied by another part of the bit fields is different; or the number of bits occupied by different bit fields in the M bit fields is different.

[0125] Another possible implementation manner of the bit field design of the DCI (hereinafter referred to as DCI bit field design manner 2) is that the first indication information is carried by one bit field (hereinafter referred to as a third bit field) in the DCI, and the bit positions included in the third bit field can be divided into P bit blocks, one bit block in the P bit blocks corresponds to one OCC scheme in the P OCC schemes, and P is an integer greater than 1. In other words, the OCC information or the index thereof corresponding to different OCC schemes in the first OCC scheme group is carried by different bit blocks in the same bit field (i.e., the third bit field) in the DCI. In this way, the OCC information corresponding to different OCC schemes in the first OCC scheme group can be quickly determined.

[0126] Optionally, P can be the total number of OCC schemes in the first OCC scheme group. For example, the first OCC scheme group includes M OCC schemes of intra-symbol OCC multiplexing, inter-symbol OCC multiplexing and inter-slot OCC multiplexing, in this case, P=M, and the bit positions included in the third bit field can be divided into M bit blocks, one bit block in the M bit blocks carries the OCC information corresponding to one OCC scheme in the M OCC schemes or the index of the OCC information.

[0127] Each bit block in the P bit blocks can correspond to at least one bit position, that is, each bit block can include at least one bit position.

[0128] Taking M=2, and the two OCC schemes included in the first OCC scheme group being a first OCC scheme and a second OCC scheme as examples, the bit positions included in the third bit field are divided into two bit blocks, and the two bit blocks are a first bit block and a second bit block, that is, the third bit field includes the first bit block and the second bit block. The first bit block carries the first OCC information or the index of the first OCC information, and the second bit block carries the second OCC information or the index of the second OCC information. That is, the first indication information is carried by the first bit block and the second bit block in the third bit field. Embodiments of the present application take the first bit block corresponding to N1 bit positions and the second bit block corresponding to N2 bit positions as examples, where N1 and N2 are positive integers.

[0129] Alternatively, P can be the total number of OCC schemes that can be supported by the terminal device, that is, the terminal device can support at most P OCC schemes, in which case P is greater than or equal to M, and the P OCC schemes at least include the M OCC schemes. The M bit blocks in the P bit blocks carry the OCC information corresponding to the M OCC schemes or the index of the OCC information corresponding to the M OCC schemes. Optionally, the other bit blocks in the P bit blocks other than the M bit blocks can carry the OCC information corresponding to the OCC schemes or the index thereof, or the other bit blocks in the P bit blocks other than the M bit blocks can not carry information, or the other bit blocks in the P bit blocks other than the M bit blocks can carry invalid information or useless information.

[0130] The DCI bit field design method 2 can also be understood as follows: the DCI at least includes an OCC information indication field for carrying first indication information, the OCC information indication field includes one bit field (that is, a third bit field), and the bit positions included in the OCC information indication field can be divided into P bit blocks, and the P bit blocks at least include two bit blocks, that is, a first bit block and a second bit block.

[0131] For example, in the case of P=M=2, a schematic diagram of the OCC information indication field can be as shown in FIG. 4. In FIG. 4, one black box represents one bit field. As shown in FIG. 4, the OCC information indication field (that is, the third bit field) is composed of a first bit block and a second bit block, where the first bit block carries the first OCC information or the index of the first OCC information, and the second bit block carries the second OCC information or the index of the second OCC information.

[0132] For example, in the case of P=3 and M=2, a schematic diagram of the OCC information indication field can be shown in FIG. 5. In FIG. 5, a black box represents a bit field. As shown in FIG. 5, the OCC information indication field (i.e., the third bit field) includes bit positions that can be divided into three bit blocks, i.e., a first bit block, a second bit block, and a third bit block. The first bit block carries first OCC information or an index of the first OCC information, the second bit block carries second OCC information or an index of the second OCC information, and the third bit block carries OCC information corresponding to other OCC schemes or an index thereof; or the third bit block does not carry information, or carries invalid information or useless information. The first bit block can correspond to N1 bit positions, the second bit block can correspond to N2 bit positions, and the third bit block can correspond to N3 bit positions, where N1, N2, and N3 are positive integers.

[0133] Embodiments of the present application do not limit the number of bit positions corresponding to each bit block in the P bit blocks. The number of bit positions corresponding to different bit blocks in the P bit blocks can be the same; or the number of bit positions corresponding to part of the bit blocks in the P bit blocks is the same, and the number of bit positions corresponding to another part of the bit blocks is the same; or the number of bit positions corresponding to different bit blocks in the P bit blocks is different. It can be understood that the values of N1, N2, and N3 can be the same or different.

[0134] In a possible implementation, the bit positions corresponding to each bit block in the P bit blocks can be agreed by a protocol or indicated by a network device. The number of bit positions corresponding to each bit block in the P bit blocks can be agreed by a protocol or configured by a network device, and embodiments of the present application do not limit this.

[0135] Optionally, the network device can send second indication information, the second indication information indicating the starting bit position of the first bit block and the starting bit position of the second bit block. Correspondingly, the terminal device receives the second indication information from the network device, and determines the bit positions corresponding to the first bit block and the second bit block based on the second indication information. In this way, the network device can indicate the starting bit position of the bit positions occupied by the OCC information corresponding to various OCC schemes in the first OCC scheme group, and the terminal device can quickly determine the bit positions corresponding to the bit blocks occupied by the OCC information corresponding to various OCC schemes based on the starting bit positions of the bit blocks occupied by the OCC information corresponding to various OCC schemes, and further, it is beneficial to quickly determine the OCC information corresponding to various OCC schemes in the first OCC scheme group. For example, in FIG. 4, the first bit block and the second bit block form a third bit field, and in the case that the bit positions occupied by the third bit field, the starting bit position of the first bit block, and the starting bit position of the second bit block are known, the bit positions corresponding to the first bit block and the second bit block can be determined.

[0136] Optionally, the terminal device can also determine the bit positions corresponding to the first bit block based on the starting bit position of the first bit block and the number of bit positions carrying the first OCC information. Similarly, the terminal device can also determine the bit positions corresponding to the second bit block based on the starting bit position of the second bit block and the number of bit positions carrying the second OCC information. For example, in FIG. 5, the first bit block, the second bit block, and the third bit block form a third bit field, and in the case that the bit positions occupied by the third bit field, the starting bit position of the first bit block, the starting bit position of the second bit block, and the starting bit position of the third bit block are known, the number of bit positions carrying the first OCC information and the number of bit positions carrying the second OCC information are obtained, and the bit positions corresponding to the first bit block, the second bit block, and the third bit block can be determined.

[0137] Optionally, the second indication information can be carried in high-layer signaling or physical-layer signaling. The high-layer signaling involved in the embodiments of the present application can include radio resource control (RRC) signaling or other signaling, and the physical-layer signaling involved in the embodiments of the present application can include medium access control (MAC CE) signaling or other signaling, which are not limited by the embodiments of the present application.

[0138] In a possible implementation, the bit positions corresponding to the first bit block and the bit positions corresponding to the second bit block can be determined based on an order between the first OCC scheme and the second OCC scheme, a quantity of bit positions carrying the first OCC information, and a quantity of bit positions carrying the second OCC information. In this way, the terminal device can quickly determine the bit positions corresponding to the first bit block and the bit positions corresponding to the second bit block, and further, facilitate quick determination of the OCC information corresponding to different OCC schemes in the first OCC scheme group.

[0139] The order between the first OCC scheme and the second OCC scheme can refer to an order between the first OCC scheme and the second OCC scheme in the first OCC scheme group. Assuming that the OCC schemes in the first OCC scheme group are arranged in the order from front to back as: the first OCC scheme, the second OCC scheme, the order of the first OCC scheme is before the order of the second OCC scheme. The OCC schemes in the first OCC scheme group are arranged in the order from front to back as: the second OCC scheme, the first OCC scheme, and the order of the first OCC scheme is after the order of the second OCC scheme.

[0140] Alternatively, the order between the first OCC scheme and the second OCC scheme can refer to an order between the first OCC scheme and the second OCC scheme in all OCC schemes supported by the terminal device. For example, all OCC schemes supported by the terminal device include intra-symbol OCC multiplexing, inter-symbol OCC multiplexing, and inter-slot OCC multiplexing, and the OCC schemes are arranged in the order from front to back as: intra-symbol OCC multiplexing, inter-symbol OCC multiplexing, and inter-slot OCC multiplexing. Assuming that the first OCC scheme is inter-symbol OCC multiplexing and the second OCC scheme is intra-symbol OCC multiplexing, the order of the first OCC scheme is the second, and the order of the second OCC scheme is the first. Assuming that the first OCC scheme is inter-slot OCC multiplexing and the second OCC scheme is intra-symbol OCC multiplexing, the order of the first OCC scheme is the third, and the order of the second OCC scheme is the first.

[0141] It can be understood that if the order of the first OCC scheme is before the order of the second OCC scheme, the bit positions corresponding to the first bit block are before the bit positions corresponding to the second bit block. Similarly, if the order of the first OCC scheme is after the order of the second OCC scheme, the bit positions corresponding to the first bit block are after the bit positions corresponding to the second bit block.

[0142] For example, in FIG. 4, the third bit field includes 10 bits in total, assuming that the order of the first OCC scheme is before the order of the second OCC scheme in the first OCC scheme group, and the number of bits carrying the first OCC information is 4 and the number of bits carrying the second OCC information is 6, then the first bit block corresponds to the first 4 bits in the third bit field, and the second bit block corresponds to the last 6 bits in the third bit field. If the number of bits carrying the first OCC information is the same as the number of bits carrying the second OCC information, both of which are 5, then the first bit block corresponds to the first 5 bits in the third bit field, and the second bit block corresponds to the last 5 bits in the third bit field.

[0143] It can be understood that, taking the number of all OCC schemes supported by the terminal device as P, the third bit can include P bit blocks. Assuming that, in all OCC schemes supported by the terminal device, the order of a certain OCC scheme (such as the first OCC scheme) in the first OCC scheme group is i, then the OCC information (i.e., the first OCC information) corresponding to the first OCC scheme or the index of the first OCC information is carried through the i th bit block in the third bit, 1≤i≤P, i is an integer, and P is an integer greater than 1.

[0144] For example, taking P=3 as an example, the third bit field can include 3 bit blocks, wherein the first bit block is used to carry the OCC information or the index of the OCC information of the OCC scheme with the order of the first position, the second bit block is used to carry the OCC information or the index of the OCC information of the OCC scheme with the order of the second position, and the third bit block is used to carry the OCC information or the index of the OCC information of the OCC scheme with the order of the third position. Taking all OCC schemes supported by the terminal device arranged in the order from front to back as: intra-symbol OCC multiplexing, inter-symbol OCC multiplexing, and inter-slot OCC multiplexing as an example, then the first bit block is used to carry the OCC information or the index of the OCC information of the intra-symbol OCC multiplexing scheme, the second bit block is used to carry the OCC information or the index of the OCC information of the inter-symbol OCC multiplexing scheme, and the third bit block is used to carry the OCC information or the index of the OCC information of the inter-slot OCC multiplexing scheme. Assuming that the first OCC scheme is intra-symbol OCC multiplexing, the second OCC scheme is inter-slot OCC multiplexing, and the number of bits carrying the first OCC information is 4 and the number of bits carrying the second OCC information is 6, then the first bit block corresponds to the first 4 bits in the third bit field, and the second bit block corresponds to the last 6 bits in the third bit field.

[0145] In a possible implementation, the number of bit positions carrying the OCC information corresponding to different OCC schemes in the first OCC scheme group can be agreed by a protocol, or can be indicated by the network device, or can be set by the terminal device by default. For example, in FIG. 5, the number of bit positions corresponding to the first bit block, the number of bit positions corresponding to the second bit block, and the number of bit positions corresponding to the third bit block can be agreed by a protocol, or can be indicated by the network device, or can be set by the terminal device by default.

[0146] In a possible implementation, the number of bit positions carrying the OCC information corresponding to different OCC schemes in the first OCC scheme group can be the same or different. For example, in FIG. 5, the number of bit positions corresponding to the first bit block, the number of bit positions corresponding to the second bit block, and the number of bit positions corresponding to the third bit block can be the same or different. It can be understood that the number of bit positions carrying the first OCC information can be the same as or different from the number of bit positions carrying the second OCC information.

[0147] Another possible implementation of the bit field design of the DCI (hereinafter referred to as DCI bit field design method 3) is as follows: the first indication information is carried by one bit field (hereinafter referred to as the fourth bit field) in the DCI. Taking the first OCC scheme group including M OCC schemes of intra-symbol OCC multiplexing, inter-symbol OCC multiplexing, and inter-slot OCC multiplexing as an example, the first indication information is carried by M bit fields in the DCI, and the fourth bit field carries the OCC information corresponding to one OCC scheme in the first OCC scheme group or the index of the OCC information, and the OCC information corresponding to other OCC schemes in the first OCC scheme group is determined based on the information (i.e., the OCC information or the index of the OCC information) carried by the fourth bit field. In this way, the number of bits occupied by the fourth bit field can be saved, and the OCC information corresponding to different OCC schemes in the first OCC scheme group can be determined.

[0148] The DCI bit field design method 3 can also be understood as follows: the DCI at least includes an OCC information indication field for carrying the first indication information, the OCC information indication field includes one bit field (i.e., the fourth bit field), the OCC information indication field explicitly indicates the OCC information of one OCC scheme in the first OCC scheme group or the index of the OCC information, and the OCC information of the remaining OCC schemes in the first OCC scheme group can be determined based on the explicitly indicated OCC information.

[0149] The embodiment of the present application takes the first OCC information corresponding to the first OCC scheme in the first OCC scheme group carried by the fourth bit field as an example, and the second OCC information corresponding to the second OCC scheme in the first OCC scheme group is determined based on the first OCC information.

[0150] For example, the schematic diagram of the OCC information indication field can be shown in FIG. 6. In FIG. 6, one black box represents one bit field. As shown in FIG. 6, the OCC information indication field includes 1 bit field (i.e., the fourth bit field), and the fourth bit field carries the first OCC information or the index of the first OCC information.

[0151] In a possible implementation, the OCC information corresponding to each OCC scheme in the first OCC scheme group is the same. Therefore, the network device indicates the OCC information of one OCC scheme in the first OCC scheme group through the first indication information, and the terminal device can determine the OCC information of all the OCC schemes in the first OCC scheme group based on the first indication information. It can be understood that the second OCC information is the same as the first OCC information. In this way, the number of bits occupied by the fourth bit field can be saved, and the second OCC information can be quickly determined.

[0152] Optionally, the OCC information corresponding to each OCC scheme in the first OCC scheme group is the same, which can be agreed by a protocol or indicated by the network device, and the embodiment of the present application does not limit this.

[0153] In a possible implementation, the OCC information corresponding to different OCC schemes has a corresponding relationship, and the terminal device can determine the OCC information corresponding to all the OCC schemes in the first OCC scheme group based on the corresponding relationship and the OCC information corresponding to one OCC scheme in the first OCC scheme group. In this way, the number of bits occupied by the fourth bit field can be saved, and the second OCC information can be quickly determined.

[0154] It can be understood that if the first indication information indicates the OCC information (i.e., the first OCC information) corresponding to the first OCC scheme in the first OCC scheme group, the OCC information (i.e., the second OCC information) corresponding to the second OCC scheme in the first OCC scheme group is the OCC information having a corresponding relationship with the first OCC information.

[0155] For example, the corresponding relationship can be shown in Table 1.

[0156] Table 1: Corresponding relationship between OCC information corresponding to different OCC schemes

[0157] Taking the first OCC scheme in the first OCC scheme group as intra-symbol OCC multiplexing and the second OCC scheme in the first OCC scheme group as inter-symbol OCC multiplexing as an example, assuming that the first indication information indicates that the first OCC information is [-1, -1, -1, -1], it can be learned based on Table 2 that the second OCC information can be [+1, +1, -1, -1]. Assuming that the first indication information indicates that the first OCC information is [+1, -1], it can be learned based on Table 2 that the second OCC information can be [+1, +1].

[0158] Optionally, the correspondence between the OCC information corresponding to different OCC schemes can be agreed by a protocol, or can be indicated by a network device, and the embodiments of the present application do not limit this.

[0159] In a possible implementation, each OCC scheme can correspond to a respective candidate OCC information set, and the candidate OCC information set corresponding to an OCC scheme can include at least one candidate OCC information corresponding to the OCC scheme. For example, the candidate OCC information set corresponding to the first OCC scheme includes at least one candidate OCC information corresponding to the first OCC scheme, and the at least one candidate OCC information corresponding to the first OCC scheme at least includes the first OCC information. The candidate OCC information set corresponding to the second OCC scheme includes at least one candidate OCC information corresponding to the second OCC scheme, and the at least one candidate OCC information corresponding to the second OCC scheme at least includes the second OCC information.

[0160] The index of the first OCC information can be an index of the first OCC information in the candidate OCC information set corresponding to the first OCC scheme, and the index of the second OCC information can be an index of the second OCC information in the candidate OCC information set corresponding to the second OCC scheme. By indicating, through the DCI, the index of the OCC information corresponding to a certain OCC scheme (such as the first OCC scheme or the second OCC scheme) in the candidate OCC information set corresponding to the OCC scheme, the number of bits occupied by the first indication information can be saved, and resources can be saved.

[0161] Optionally, the candidate OCC information set can be presented in the form of a list or in other manners, and the embodiments of the present application do not limit this. The embodiments of the present application take the candidate OCC information set presented in the form of a list as an example, in which case the candidate OCC information set can also be referred to as a candidate OCC information list, and the candidate OCC information list includes at least one candidate OCC information.

[0162] For example, the candidate OCC information list corresponding to the intra-symbol OCC multiplexing scheme can be shown in Table 2, the candidate OCC information list corresponding to the inter-symbol OCC multiplexing scheme can be shown in Table 3, and the candidate OCC information list corresponding to the inter-slot OCC multiplexing scheme can be shown in Table 4.

[0163] Table 2: Candidate OCC information list corresponding to intra-symbol OCC multiplexing scheme

[0164] Table 3: Candidate OCC information list corresponding to inter-symbol OCC multiplexing scheme

[0165] Table 4: Candidate OCC information list corresponding to inter-slot OCC multiplexing scheme

[0166] For example, assuming that the first OCC scheme is the intra-symbol OCC multiplexing scheme and the index of the first OCC information is 0, the OCC information corresponding to the first OCC scheme (i.e., the first OCC information) is the candidate OCC information corresponding to the index 0 in Table 2, i.e., [-1, -1, -1, -1].

[0167] For example, assuming that the first OCC scheme is the inter-symbol OCC multiplexing scheme and the index of the first OCC information is 2, the OCC information corresponding to the first OCC scheme (i.e., the first OCC information) is the candidate OCC information corresponding to the index 2 in Table 3, i.e., [+1, +1].

[0168] In a possible implementation, the candidate OCC information set corresponding to each OCC scheme can be agreed by a protocol or can be indicated by the network device, and the embodiments of the present application do not limit this. For example, the network device can send third indication information, and the third indication information configures the candidate OCC information set corresponding to at least one of the intra-symbol OCC multiplexing, the inter-symbol OCC multiplexing, and the inter-slot OCC multiplexing. The candidate OCC information set corresponding to one OCC scheme includes at least one candidate OCC information corresponding to the OCC scheme. Correspondingly, the terminal device can receive the third indication information from the network device.

[0169] Optionally, one OCC scheme can correspond to one or more candidate OCC information sets. Taking an example of that the first OCC scheme corresponds to three candidate OCC information sets, assuming that the index of the first OCC information is the index in the first candidate OCC information set, wherein the first candidate OCC information set is one of the three candidate OCC information sets. Optionally, the first candidate OCC information set can be agreed by a protocol, or can be indicated by the network device, and the embodiments of the present application do not make any limitation in this regard. For example, the network device can indicate through high layer signaling which of the three candidate OCC information sets is used to determine the first OCC information.

[0170] Optionally, the third indication information can be carried in high layer signaling or physical layer signaling.

[0171] In a possible implementation, each OCC scheme group can correspond to a respective candidate OCC information set group, one candidate OCC information set group includes at least one candidate OCC information set corresponding to one OCC scheme group, and one candidate OCC information set includes candidate OCC information corresponding to each OCC scheme in one OCC scheme group.

[0172] Optionally, the candidate OCC information set group can be presented in the form of a list or in other forms, and the embodiments of the present application do not make any limitation in this regard. Taking an example of that the candidate OCC information set group is presented in the form of a list, in this case, the candidate OCC information set group can also be referred to as a candidate OCC information set list, and the candidate OCC information set list includes at least one candidate OCC information set.

[0173] For example, the candidate OCC information set list corresponding to the scheme group (hereinafter referred to as OCC scheme group 1) obtained by combining the intra-symbol OCC multiplexing and the inter-symbol OCC multiplexing can be as shown in Table 5. The candidate OCC information set list corresponding to the scheme group (hereinafter referred to as OCC scheme group 2) obtained by combining the intra-symbol OCC multiplexing and the inter-slot OCC multiplexing can be as shown in Table 6. The candidate OCC information set list corresponding to the scheme group (hereinafter referred to as OCC scheme group 3) obtained by combining the intra-symbol OCC multiplexing, the inter-symbol OCC multiplexing and the inter-slot OCC multiplexing can be as shown in Table 7.

[0176] Table 7: OCC scheme group 3 corresponding candidate OCC information group list

[0177] In Table 5, one row represents one candidate OCC information group corresponding to OCC scheme group 1, and one candidate OCC information group includes candidate OCC information corresponding to each OCC scheme in OCC scheme group 1. In Table 6, one row represents one candidate OCC information group corresponding to OCC scheme group 2, and one candidate OCC information group includes candidate OCC information corresponding to each OCC scheme in OCC scheme group 2. In Table 7, one row represents one candidate OCC information group corresponding to OCC scheme group 3, and one candidate OCC information group includes candidate OCC information corresponding to each OCC scheme in OCC scheme group 1.

[0178] Another possible implementation of the bit field design of the DCI (hereinafter referred to as DCI bit field design method 4) regarding the first indication information is carried by one bit field (hereinafter referred to as the fifth bit field) in the DCI, and the fifth bit field carries the index of the OCC information corresponding to the first OCC scheme group, and the OCC information corresponding to the first OCC scheme group is one candidate OCC information group in the first candidate OCC information group set, and the first candidate OCC information group set includes at least one candidate OCC information group corresponding to the first OCC scheme group, and the candidate OCC information group corresponding to the first OCC scheme group includes candidate OCC information corresponding to the first OCC scheme and candidate OCC information corresponding to the second OCC scheme. By indicating the index of the OCC information corresponding to the first OCC scheme group in the first candidate OCC information group set through the fifth bit field, it is beneficial to save the number of bits occupied by the fifth bit field and save resources.

[0179] The DCI bit field design method 4 can also be understood as: the DCI at least includes an OCC information indication field for carrying the first indication information, and the OCC information indication field includes 1 bit field (i.e. the fifth bit field), and the OCC information indication field carries the index of the OCC information corresponding to the first OCC scheme group.

[0180] For example, the schematic diagram of the OCC information indication field can be as shown in FIG. 7. In FIG. 7, a black box represents a bit field. As shown in FIG. 7, the OCC information indication field includes 1 bit field (i.e. the fifth bit field), and the fifth bit field carries the index of the OCC information corresponding to the first OCC scheme group.

[0181] Taking the first OCC scheme group, OCC scheme group 1, as an example, the first candidate OCC information group set can be as shown in Table 3. Assuming that the index of the OCC information corresponding to the first OCC scheme group is 0, the OCC information corresponding to the first OCC scheme group includes the candidate OCC information group corresponding to the index 0 in Table 5. Specifically, the OCC information corresponding to the first OCC scheme group includes the OCC information corresponding to intra-symbol OCC multiplexing and the OCC information corresponding to inter-symbol OCC multiplexing. The OCC information corresponding to intra-symbol OCC multiplexing is the candidate OCC information corresponding to intra-symbol OCC multiplexing with the index 0 in Table 5 (namely [-1, -1, -1, -1]). The OCC information corresponding to inter-symbol OCC multiplexing is the candidate OCC information corresponding to inter-symbol OCC multiplexing with the index 0 in Table 5 (namely [+1, +1, -1, -1]).

[0182] In a possible implementation, the candidate OCC information group set corresponding to each OCC scheme group can be agreed by a protocol or indicated by a network device, and the embodiments of the present application do not limit this.

[0183] For example, the network device can send fourth indication information, and the fourth indication information configures at least one candidate OCC information group set corresponding to at least one OCC scheme group, and the at least one candidate OCC information group set includes at least the first candidate OCC information group set. Correspondingly, the terminal device receives the fourth indication information. It can be understood that the fourth indication information can configure the candidate OCC information group set corresponding to at least one of the OCC scheme groups mentioned in the foregoing.

[0184] Optionally, the fourth indication information can be carried in high-layer signaling or physical layer signaling.

[0185] Optionally, one OCC scheme group can correspond to one or more candidate OCC information group sets. Taking the first OCC scheme group corresponding to four candidate OCC information group sets as an example, the index (namely the index of the OCC information corresponding to the first OCC scheme group) carried in the fifth bit field is an index in the first candidate OCC information group set, and the first candidate OCC information group set is one of the four candidate OCC information group sets. Optionally, the first candidate OCC information group set can be agreed by a protocol or indicated by a network device, and the embodiments of the present application do not limit this.

[0186] For example, the network device sends fifth indication information, and the fifth indication information indicates that the OCC information corresponding to the first OCC scheme group is determined through the first candidate OCC information group set. Correspondingly, the terminal device receives the fifth indication information. In this way, the network device can indicate which candidate OCC information group set in the four candidate OCC information group sets is used to determine the OCC information corresponding to the first OCC scheme group.

[0187] It should be noted that the fifth indication information indicating that the OCC information corresponding to the first OCC scheme group is determined through the first candidate OCC information group set can mean that the OCC scheme group corresponding to the first candidate OCC information group set is activated.

[0188] In the embodiments of the present application, the activation of a certain OCC scheme group can mean that the terminal device needs to determine the OCC information corresponding to each OCC scheme in the OCC scheme group when performing data transmission, and apply the OCC information corresponding to each OCC scheme in the OCC scheme group when performing data transmission, that is, the terminal device applies the OCC information corresponding to each OCC scheme in the OCC scheme group to expand the data transmission.

[0189] In the embodiments of the present application, the activation of a certain OCC scheme group can also mean that the terminal device applies the candidate OCC information group set corresponding to the OCC scheme group. The terminal device applying the candidate OCC information group set corresponding to the OCC scheme group can mean that the terminal device determines the OCC information corresponding to each OCC scheme in the OCC scheme group through the candidate OCC information group set corresponding to the OCC scheme group when performing data transmission, and expands the data transmission through the OCC information corresponding to each OCC scheme in the OCC scheme group. That is, determining which OCC scheme group is activated also determines which candidate OCC information group set is used to determine the OCC information used by the terminal device. The implementation of expanding the data transmission through the OCC information can be referred to the foregoing description, and will not be described here.

[0190] Similarly, in the embodiments of the present application, the activation of a certain OCC scheme can mean that the terminal device needs to determine the OCC information corresponding to the OCC scheme when performing data transmission, and expand the data transmission through the OCC information corresponding to the OCC scheme. The activation of a certain OCC scheme can also mean that the terminal device can apply the candidate OCC information set corresponding to the OCC scheme. The application of the candidate OCC information set corresponding to the OCC scheme by the terminal device means that the terminal device determines the OCC information corresponding to the OCC scheme through the candidate OCC information set corresponding to the OCC scheme when performing data transmission, and expands the data transmission through the OCC information corresponding to the OCC scheme. That is, determining which OCC scheme is activated also determines which candidate OCC information set is used to determine the OCC information adopted by the terminal device.

[0191] Optionally, the fifth indication information can be carried in high-layer signaling or physical layer signaling.

[0192] In a possible implementation, the network device can send sixth indication information, and the sixth indication information indicates the activation of a first OCC scheme group in at least one OCC scheme group. Correspondingly, the terminal device receives the sixth indication information. The at least one OCC scheme group can refer to at least one OCC scheme group supported by the terminal device. Through the sixth indication information, one of the OCC scheme groups supported by the terminal device (i.e., the first OCC scheme group) can be activated.

[0193] Based on the sixth indication information, the terminal device can determine that the OCC information determined by the first indication information is the OCC information corresponding to the first OCC scheme group, or the OCC information indicated by the first indication information is the OCC information corresponding to the activated OCC scheme group, and the terminal device can determine which OCC scheme group is activated based on the sixth indication information.

[0194] Optionally, the sixth indication information can be carried in high-layer signaling or physical layer signaling.

[0195] It should be noted that in the embodiments of the present application, the following descriptions represent the same meaning and can be used alternatively: "activation of an OCC scheme group", "configuration of an OCC scheme group", and "enabling of an OCC scheme group".

[0196] In a possible implementation, the network device can send seventh indication information, and the seventh indication information indicates the activation of a second OCC scheme, or the seventh indication information indicates the deactivation of the second OCC scheme. Correspondingly, the terminal device receives the seventh indication information. The deactivation can be described as disabling.

[0197] Taking the case of the first OCC scheme being activated by default as an example, it is assumed that the seventh indication information received by the terminal device indicates that the second OCC scheme is activated. In this case, the OCC scheme group (i.e., the first OCC scheme group) obtained by combining the first OCC scheme and the second OCC scheme is in an activated state, that is, the terminal device can apply the first OCC scheme group in the activated state. By indicating the activation of the second OCC scheme through the seventh indication information, the terminal device can be switched from applying the first OCC scheme to applying the first OCC scheme group, which is beneficial to improving the flexibility of the terminal device in applying multiplexing technology.

[0198] Taking the case of the first OCC scheme group being in an activated state as an example, it is assumed that the seventh indication information received by the terminal device indicates that the second OCC scheme is disabled. In this case, the first OCC scheme group is switched from the activated state to the disabled state (or the inactivated state), that is, the terminal device can not apply the first OCC scheme group in the disabled state, and the terminal device is switched from applying the first OCC scheme group to applying the first OCC scheme. By indicating the disabling of the second OCC scheme through the seventh indication information, the flexibility of the terminal device in applying multiplexing technology is improved.

[0199] Optionally, the seventh indication information can be carried in high-layer signaling or physical layer signaling.

[0200] In a possible implementation, the terminal device can send eighth indication information, and the eighth indication information can indicate whether the OCC scheme group is supported, that is, the eighth indication information can indicate whether multiple OCC schemes are combined. Correspondingly, the network device receives the eighth indication information, and then learns whether the OCC scheme group is supported by the terminal device.

[0201] In a possible implementation, the terminal device can send the eighth indication information based on its capability information. The capability information of the terminal device can indicate one or more of the following: whether the terminal device supports the OCC scheme group, whether the terminal device supports multiple OCC schemes, whether the terminal device supports the time domain OCC scheme and the frequency domain OCC scheme, and which OCC scheme or OCC schemes are supported by the terminal device.

[0202] Optionally, in response to the terminal device supporting the OCC scheme group, the terminal device can send the eighth indication information to the network device, and correspondingly, the network device receives the eighth indication information and can learn that the terminal device supports the OCC scheme group. It can be understood that, in the case that the terminal device does not support the OCC scheme group, the terminal device can not send the eighth indication information, and correspondingly, in response to not receiving the eighth indication information, the network device can consider that the terminal device does not support the OCC scheme group.

[0203] Optionally, in response to the terminal device supporting multiple OCC schemes, the terminal device can send eighth indication information to the network device, and accordingly, the network device can learn that the terminal device supports a group of OCC schemes in response to receiving the eighth indication information. In response to the terminal device not supporting OCC schemes or supporting only one OCC scheme, the terminal device can not send the eighth indication information, and accordingly, the network device can consider that the terminal device does not support a group of OCC schemes in response to not receiving the eighth indication information.

[0204] Optionally, the eighth indication information indicating support for a group of OCC schemes can indicate support for one or more of the following groups of OCC schemes: a group of schemes obtained by combining intra-symbol OCC multiplexing and inter-symbol OCC multiplexing, a group of schemes obtained by combining intra-symbol OCC multiplexing and inter-slot OCC multiplexing, a group of schemes obtained by combining inter-symbol OCC multiplexing and inter-slot OCC multiplexing, and a group of schemes obtained by combining intra-symbol OCC multiplexing, inter-symbol OCC multiplexing, and inter-slot OCC multiplexing.

[0205] Alternatively, the eighth indication information indicating support for a group of OCC schemes can indicate support for one or more of the following groups of OCC schemes: a group of schemes obtained by combining intra-symbol OCC multiplexing and inter-symbol OCC multiplexing, and a group of schemes obtained by combining intra-symbol OCC multiplexing and inter-slot OCC multiplexing.

[0206] Optionally, the eighth indication information can be carried in high-layer signaling or physical-layer signaling.

[0207] In one possible implementation, the terminal device can send ninth indication information, and the ninth indication information can indicate at least one group of OCC schemes supported by the terminal device, the at least one group of OCC schemes including the first group of OCC schemes. In this way, the terminal device can indicate to the network device which group or groups of OCC schemes are specifically supported, so that the network device can learn in more detail which group or groups of OCC schemes are specifically supported by the terminal device. It can be understood that the network device can select one of the group or groups of OCC schemes as the first group of OCC schemes after learning which group or groups of OCC schemes are specifically supported by the terminal device.

[0208] Optionally, the ninth indication information can include an index of at least one group of OCC schemes supported by the terminal device.

[0209] In one possible implementation, the terminal device can send the ninth indication information based on self-capability information. Details of the capability information of the terminal device can be found in the foregoing description, which will not be repeated here.

[0210] Optionally, the ninth indication information can be carried in high layer signaling or physical layer signaling.

[0211] In a possible implementation, the terminal device can send tenth indication information, which can indicate at least one supported OCC scheme. Correspondingly, the network device receives the tenth indication information and can learn which OCC scheme or schemes the terminal device supports.

[0212] Taking an example of the tenth indication information indicating that the terminal device supports M OCC schemes in intra-symbol OCC multiplexing, inter-symbol OCC multiplexing and inter-slot OCC multiplexing, M is an integer greater than or equal to 2. Assuming that the terminal device supports combination of at least two OCC schemes for OCC multiplexing, in this case, the eighth indication information indicating that the OCC scheme group is supported can mean that the terminal device supports one or more scheme groups obtained by combination of at least two of the M OCC schemes, or that the terminal device supports one or more scheme groups obtained by combination of at least one time-domain OCC scheme and at least one frequency-domain OCC scheme in the M OCC schemes. Assuming that the terminal device supports combination of two OCC schemes for OCC multiplexing, in this case, the eighth indication information indicating that the OCC scheme group is supported can mean that the terminal device supports one or more scheme groups obtained by combination of two of the M OCC schemes, or that the terminal device supports one or more scheme groups obtained by combination of one time-domain OCC scheme and one frequency-domain OCC scheme in the M OCC schemes.

[0213] Taking an example of the tenth indication information indicating that the terminal device supports intra-symbol OCC multiplexing, inter-symbol OCC multiplexing and inter-slot OCC multiplexing, in this case, the eighth indication information can indicate that the terminal device supports one or more of the following OCC scheme groups: a scheme group obtained by combination of intra-symbol OCC multiplexing and inter-symbol OCC multiplexing, a scheme group obtained by combination of intra-symbol OCC multiplexing and inter-slot OCC multiplexing, a scheme group obtained by combination of inter-symbol OCC multiplexing and inter-slot OCC multiplexing, and a scheme group obtained by combination of intra-symbol OCC multiplexing, inter-symbol OCC multiplexing and inter-slot OCC multiplexing.

[0214] Alternatively, the eighth indication information can indicate that the terminal device supports one or more of the following OCC scheme groups: a scheme group obtained by combination of intra-symbol OCC multiplexing and inter-symbol OCC multiplexing, a scheme group obtained by combination of intra-symbol OCC multiplexing and inter-slot OCC multiplexing, and a scheme group obtained by combination of intra-symbol OCC multiplexing, inter-symbol OCC multiplexing and inter-slot OCC multiplexing.

[0215] Optionally, the tenth indication information can be carried in high layer signaling or physical layer signaling.

[0216] It should be noted that the eighth indication information and the tenth indication information can be carried in the same message, in which case the terminal device can indicate the OCC scheme indicated by itself and whether to support combination of multiple OCC schemes to the network device through one message. Alternatively, the eighth indication information and the tenth indication information can be carried in different messages.

The bus is represented by a thick line in FIG. 9, and the connection between other components is only schematically illustrated and is not limited thereto. The bus can be divided into an address bus, a data bus, a control bus, etc. For convenience, only one thick line is used to represent the bus in FIG. 9, but it does not mean that there is only one bus or only one type of bus.
