[0004] Currently, the information indicated by DCI is limited, and the dimensions of the information indicated by DCI need to be expanded. Summary of the Invention

[0058] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0059] The technical solutions provided in this application can be applied to communication systems, which can be second-generation (2G) communication systems, third-generation (3G) communication systems, LTE systems, fifth-generation (5G) communication systems, LTE and 5G hybrid architectures, 5G new radio (5G NR) systems, and new communication systems that will emerge in the future development of communication, etc. This application does not specifically limit these.

[0060] The communication system includes a first device and a second device. The first device can be a network-side device used to provide network communication functions; in some cases, it is also called a network device or network element. The network device can typically be a base station (including functional units of a base station, or a combination of functional units of base stations) or a core network unit. The core network unit can be a functional unit within the core network, including but not limited to access and mobility management function (AMF) units or session management function (SMF) units. The second device can be a device accessing the network, typically a terminal. An example of a communication system is shown in Figure 1, which includes a base station 100 and a terminal 200.

[0061] In this embodiment, base station 100 can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB, eNB, or e-NodeB) in Long Term Evolution (LTE), base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in New Radio (NR), base stations in subsequent 3GPP evolutions, access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. Base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, or balloon stations, etc. Base stations can include one or more co-located or non-co-located transmission reception points (TRPs). Base stations can also be radio controllers, centralized units (CUs), and / or distributed units (DUs) in cloud radio access network (CRAN) scenarios. Base stations can communicate with terminal 200, or communicate with terminal 200 through relay stations. Terminal 200 can communicate with multiple base stations using different technologies. For example, the terminal can communicate with base stations that support LTE networks, base stations that support 5G networks, and can also establish dual connections with both LTE and 5G base stations.

[0062] In the embodiments of this application, the terminal 200 can be in various forms, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, vehicle-mounted terminal device, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, wearable terminal device, etc. The terminal may also be referred to as terminal equipment, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, wireless communication equipment, UE agent, or UE device, etc. The terminal can also be a fixed terminal or a mobile terminal.

[0063] In the field of wireless communication, downlink control information (DCI) is key information sent by network devices to terminals, used to indicate resource allocation, scheduling information, power control commands, etc.

[0064] Taking DCI 1-0 scrambled with paging-radio network tempory identity (P-RNTI) as an example, DCI 1-0 includes multiple fields, such as a short messages indicator and other fields, which can be used for information indication. Table 1 below shows the information indicated by DCI 1-0 represented by different values ​​of the short messages indicator.

[0065] Table 1. Short Message Indicators for DCI 1-0

[0066] As shown in Table 1, when the value of the short message indicator in DCI1_0 is 00, the fields of DCI1_0 are reserved. This means that paging scheduling information, tracking reference signal (TRS) availability, and short messages are not indicated in DCI1_0.

[0067] When the short message indicator value in DCI1_0 is 01, DCI1_0 is used to indicate the availability of TRS and paging scheduling information. Specifically, DCI1_0 includes field 1 and field 2. Field 1 includes indication information of TRS availability, and field 2 includes indication information of paging scheduling. Furthermore, DCI1_0 also includes a reserved field, which is not used for message indication and includes a first number of bits.

[0068] When the short message indicator value in DCI1_0 is 10, DCI1_0 is used to indicate the availability of TRS and short messages. DCI1_0 includes fields 1 and 3. Field 1 includes information indicating the availability of TRS, and field 3 includes information indicating short messages. Additionally, DCI1_0 also includes a reserved field, which is not used for message indication and includes a second number of bits.

[0069] When the short message indicator value in DCI1_0 is 11, DCI1_0 is used to indicate TRS availability, paging scheduling information, and short messages. DCI1_0 includes fields 1, 2, and 3. Field 1 includes TRS availability indication information, field 2 includes paging scheduling information indication information, and field 3 includes short message indication information. Furthermore, DCI1_0 also includes a reserved field, which is not used for information indication. The reserved field includes a third number of bits; this third number is less than the first and second numbers.

[0070] This shows that the value of the short message indicator in DCI1_0 is 00, all fields of DCI1_0 are reserved and do not indicate any information, the values ​​of the short message indicator in DCI1_0 are 01, 10 and 11, and DCI1_0 also includes reserved fields that do not indicate any information.

[0071] Based on this, the information indication method provided in this application embodiment can utilize the reserved fields in DC1_0 for information indication, thereby expanding the indication dimension of DCI. Of course, the information indication method provided in this application embodiment can also apply other DCI formats; DC1_0 will be used as an example for description below.

[0072] As shown in Figure 2, the information indication method provided in this embodiment includes:

[0073] S201. The network device sends DCI, and the corresponding terminal receives DCI.

[0074] Understandable: DCI sent by network devices is used to indicate information.

[0075] The DCI includes a short message indicator and a first field. The first field includes reserved bits in the DCI, and the short message indicator is a first value used to indicate that the first field includes indicator information. In some embodiments, the short message indicator is usually located at the beginning of the DCI, and the first field is located after the short message indicator, but this does not constitute a restriction on the order of information in the DCI.

[0076] In some embodiments, the DCI format is DCI 1-0 scrambled with P-RNTI.

[0077] The information indicated by the DCI 1-0 sent by the network device includes at least one of the following: TRS availability indication information, paging scheduling information indication information, and short message indication information, and also includes indication information included in the first field.

[0078] It is understood that DCI 1-0 includes other fields, which include at least one of the following: TRS availability indication information, paging scheduling information indication information, and short message indication information. The indication information included in the first field is distinct from the TRS availability indication information, paging scheduling information indication information, and short message indication information. In some embodiments, the other fields may be located between the short message indicator and the first field, but this does not constitute a restriction on the order of information in the DCI.

[0079] In some embodiments, the first field may include indication information associated with a first function, a first message, and / or a first public channel.

[0080] The first function can refer to: functions related to full-duplex communication, functions related to non-terrestrial network (NTN) communication, and / or functions related to AI, etc.

[0081] The first message can refer to: the synchronization signal block (SS / PBCH block, SSB) and / or the system information block (SIB), etc.

[0082] The first common channel can refer to the physical random access channel (PRACH), etc.

[0083] Based on this, the indication information included in the first field may include one or more of the following indication information:

[0084] Instructions for functions related to full-duplex.

[0085] Indication information for functions related to communication with non-terrestrial networks (NTN).

[0086] Instructions for AI-related functions.

[0087] Indication information for functions associated with the synchronization signal block (SS / PBCH block, SSB), such as indication information for SSB activation or deactivation. SSB activation can be understood as activating the network device to send the SSB, and SSB deactivation can be understood as the network device canceling the sending of the SSB. Another example is the indication information for the time domain resources of the SSB, which is used to indicate different activation times of the SSB.

[0088] Indication information for functions associated with the system information block (SIB), such as indication information for SIB activation or deactivation. SIB activation can be understood as activating the network device to send the SIB, and SIB deactivation can be understood as the network device canceling the sending of the SIB. Another example is the indication information for the time domain resources of the SIB, which is used to indicate different activation times of the SIB.

[0089] Indication information of resources for one or more common channels, wherein the resources of the common channels include at least one of time-domain resources, frequency-domain resources, spatial-domain resources, and code-domain resources.

[0090] It should be noted that the indication information included in the first field is not limited to the types mentioned above; the first field can also indicate other information. For example, the first field can also indicate the indication information of the paging time domain resources, used to indicate different activation times of paging.

[0091] In one application scenario, PRACH resources (such as time-domain and frequency-domain resources) are configured by network devices via SIBs. Therefore, the PRACH resource adjustment cycle is too long and inflexible. Furthermore, the increase in the number of terminals joining the network is a gradual process; as the number of terminals increases, frequent adjustments to PRACH resources may be necessary. Configuring PRACH resources solely through SIBs is insufficient for handling such frequent adjustments.

[0092] In view of this, one implementation method is to indicate the adjustment method of PRACH resources through DCI, that is, to indicate the availability of PRACH resources through the indication information included in the first field of DCI. The availability of resources may include: resources are unavailable, resources are available, some resources (one or more sub-resources) are available, some resources (one or more sub-resources) are unavailable, etc. In this way, dynamic adjustment of PRACH resources is realized, and the adjustment method is flexible and convenient.

[0093] The resources of PRACH include at least one of the following: time-domain resources, frequency-domain resources, spatial-domain resources, and code-domain resources. Taking time-domain resources as an example, the availability of time-domain resources includes: time-domain resources are unavailable, time-domain resources are available, one or more subsets of time-domain resources are available, or one or more subsets of time-domain resources are unavailable.

[0094] As shown in Table 1, the short message indicator in DCI 1-0 typically includes two digits with values ​​of 00, 01, 10, and 11. Specifically, the first value can be 00, 01, 10, or 11; where 00 is a reserved value, and 01, 10, and 11 are non-reserved values. This can be understood as follows: a reserved first value indicates that all fields in DCI 1-0 are reserved and not used for information indication; a non-reserved first value indicates that some or all fields in DCI 1-0 are used to indicate information.

[0095] The way DCI 1-0 indicates information differs depending on the value of the short message indicator in DCI 1-0. The following text will explain the way DCI 1-0 indicates information for different values ​​of the short message indicator in DCI 1-0.

[0096] In one implementation, the short message indicator in DCI 1-0 is the first value, which is a reserved value, such as 00.

[0097] The short message indicator in DCI1_0 has a value of 00. Paging scheduling information, TRS availability indicators, and short messages are not indicated in DCI1_0.

[0098] In some embodiments, as shown in Figure 3(a), all bits of DCI1_0 except for the short message indicator are reserved bits, and the first field includes reserved bits, which can be used for information indication. This achieves the use of sufficient bits for information indication, thereby improving the reliability of information transmission. It is understood that the indication information included in the first field is N bits, where N is greater than or equal to 1, and does not necessarily occupy all the reserved bits of DCI1_0.

[0099] In other embodiments, as shown in Figure 3(b), some reserved bits of DCI1_0 are used as a first field for information indication, and some reserved bits are used as a second field for indicating at least one of TRS availability, paging scheduling information, and short message. That is, DCI1_0 includes: a short message indicator, a first field, and a second field. Both the first and second fields are reserved bits of DCI1_0. The first field includes the indication information mentioned above, occupying N bits, where N is greater than or equal to 1. The second field includes at least one of TRS availability indication information, paging scheduling information indication information, and short message indication information. The short message indication information can occupy 8 bits, the paging scheduling information indication information can occupy 2 bits, and the TRS availability indication information occupies M bits, where M is 1, 2, 3, 4, 5, or 6 bits.

[0100] This embodiment utilizes the reserved bits of DCI1_0 to indicate the availability of TRS, paging scheduling information, short messages, and other information, thereby expanding the indication dimensions of DCI1_0.

[0101] In some embodiments, the fields in DCI1_0 are ordered as follows: short message indicator, second field, and first field. Similarly, this does not constitute a limitation.

[0102] The method by which DCI1_0 indicates the availability of TRS can be found in the relevant protocol content, and will not be repeated here.

[0103] Based on the foregoing, the first field includes: a first function, an indication of a first message and / or a first common channel. The network device is configured to include this indication information in the first field as follows:

[0104] Method 1, as shown in Figure 4, includes a first bit and a second bit. The first bit is used to indicate a first function, a first message and / or a first common channel, and the second bit is used to indicate the indication information associated with the first function indicated by the first bit, the first message and / or the first common channel.

[0105] The value of the first bit indicates the first function, the first message, and / or the first common channel. The first bit may include one or more bits, and different values ​​of one or more bits can indicate the first function, the first message, and / or the first common channel. Based on this, the terminal can determine which function, message, or common channel the first field indicates based on the value of the first bit.

[0106] The value of the second bit is used to indicate the first function, first message, and / or indication information associated with the first common channel indicated by the first bit. The first bit may include one or more bits, and different values ​​of one or more bits may indicate the first function, first message, and / or indication information associated with the first common channel indicated by the first bit. Based on this, the terminal can determine the content of the indication information included in the first field based on the value of the second bit.

[0107] It is understandable that, depending on the object indicated by the first bit, the number of bits included in the second bit may be the same or different. For example, if the value of the first bit indicates a first function, the second bit may include 2 bits to indicate the association information of the first function; or if the value of the first bit indicates a first common channel, the second bit may include 3 bits to indicate the indication information associated with the first common channel.

[0108] Furthermore, for different objects of the same type indicated by the first bit, the number of bits included in the second bit can be the same or different. For example, the value of the first bit indicates a first function, and the second bit includes 2 bits to indicate the association information of the first function; the value of the first bit indicates another first function, and the second bit includes 3 bits to indicate the association information of the first function.

[0109] For example, the first field includes indications of the availability of PRACH time-domain resources, indications of SIB activation or deactivation, and indications of paging time-domain resources.

[0110] The first bit consists of 2 bits. When the value of the 2 bits is 00, the first field is used to indicate the availability of time-domain resources for PRACH; when the value of the 2 bits is 01, the first field is used to indicate the time-domain resources for SSB; when the value of the 2 bits is 10, the first field is used to indicate the time-domain resources for paging.

[0111] For the time-domain resource indicated by the first bit as PRACH, the second bit consists of 3 bits: one bit with a value of 0 indicates that the time-domain resource is unavailable; and one bit with a value of 1 indicates that the time-domain resource is available. Assume that the time-domain resource of PRACH includes 3 subsets.

[0112] When 3 bits are 000, the first field indicates that the time-domain resource of PRACH is unavailable; when 3 bits are 001, the first field indicates that subset 1 of the time-domain resource of PRACH is available; when 3 bits are 010, the first field indicates that subset 2 of the time-domain resource of PRACH is available; when 3 bits are 100, the first field indicates that subset 3 of the time-domain resource of PRACH is available; when 3 bits are 011, the first field indicates that subsets 1 and 2 of the time-domain resource of PRACH are available, and so on; when 3 bits are 111, the first field indicates that the time-domain resource of PRACH is available.

[0113] The first bit indicates whether the SIB is activated or deactivated. The second bit consists of 1 bit, where a value of 0 indicates that the SIB is deactivated, and a value of 1 indicates that the SIB is activated.

[0114] For the first bit indicating the time-domain resource of paging, the second bit consists of 2 bits: one bit with a value of 0 indicates paging deactivated; the other bit with a value of 1 indicates paging activated. Assume paging has two activation opportunities. If the 2 bits are 00, the first field indicates paging deactivated; if the 2 bits are 01, the first field indicates paging activated at opportunity 1; if the 2 bits are 10, the first field indicates paging activated at opportunity 2; and if the 2 bits are 11, the first field indicates paging activated at both opportunity 1 and opportunity 2.

[0115] In one example, taking the arrangement of fields in DCI 1-0 as short message indicator first followed by the first field, the network device sends DCI 1-0 as 0000100. The terminal receives this DCI 1-0 and parses the bit values ​​in it. It can be determined that: the first two bits (i.e., short message indicator) are 00, indicating that DCI 1-0 is reserved to indicate other information (not the availability of TRS, paging scheduling information, or short message information); the third and fourth bits are 00, indicating that this DCI 1-0 is used to indicate the time domain resources of PRACH; and the last three bits are 100, indicating that subset 3 of the time domain resources of PRACH is available, while other subsets are unavailable.

[0116] Method 2, as shown in Figure 5, includes one or more fields in the first field. The position of each field in the DCI indicates a first function, a first message, and / or a first common channel. The value of each field indicates the indication information associated with the first function, the first message, and / or the first common channel. Each field may include one or more bits. The first field may include multiple fields, and the number of bits included in each field may be the same or different.

[0117] For example, the first field includes indications of the availability of PRACH time-domain resources, indications of SIB activation or deactivation, and indications of paging time-domain resources. Based on this, the first field comprises three fields: the first field includes indications of the availability of PRACH time-domain resources, the second field includes indications of SIB activation or deactivation, and the third field includes indications of paging time-domain resources.

[0118] The first field consists of 3 bits: a value of 0 indicates that the time-domain resource is unavailable, and a value of 1 indicates that the time-domain resource is available. Assume that the PRACH time-domain resource consists of 3 subsets.

[0119] When 3 bits are 000, the first field indicates that the time-domain resource of PRACH is unavailable; when 3 bits are 001, the first field indicates that subset 1 of the time-domain resource of PRACH is available; when 3 bits are 010, the first field indicates that subset 2 of the time-domain resource of PRACH is available; when 3 bits are 100, the first field indicates that subset 3 of the time-domain resource of PRACH is available; when 3 bits are 011, the first field indicates that subsets 1 and 2 of the time-domain resource of PRACH are available, and so on; when 3 bits are 111, the first field indicates that the time-domain resource of PRACH is available.

[0120] The second field includes 1 bit. A value of 0 indicates that the SIB is deactivated, and a value of 1 indicates that the SIB is activated.

[0121] The third field consists of 2 bits. One bit is 0, indicating paging is deactivated; the other bit is 1, indicating paging is activated. Assume paging has two activation opportunities. If the 2 bits are 00, the first field indicates paging is deactivated; if the 2 bits are 01, the first field indicates paging is activated at opportunity 1; if the 2 bits are 10, the first field indicates paging is activated at opportunity 2; and if the 2 bits are 11, the first field indicates paging is activated at both opportunity 1 and opportunity 2.

[0122] In another example, taking the arrangement of fields in DCI 1-0 as short message indicator first followed by the first field, the network device sends DCI 1-0 as 00001000. The terminal receives this DCI 1-0 and parses the bit values ​​in it. It can be determined that: the first two bits (i.e., short message indicator) are 00, indicating that DCI 1-0 is reserved to indicate other information (not the availability of TRS, paging scheduling information, or short message information); the third to fifth bits are 001, indicating that DCI 1-0 is used to indicate that the time domain resource of PRACH is unavailable; the sixth bit is 0, indicating that DCI 1-0 is used to indicate SIB deactivation; and the last two bits are 00, indicating that DCI 1-0 is used to indicate paging deactivation.

[0123] In another implementation, the short message indicator in DCI 1-0 is the first value, which is a non-reserved value, such as 01.

[0124] The short message indicator in DCI1_0 has a value of 01. Paging scheduling information and TRS availability indicators are indicated in DCI1_0, but short messages are not indicated in DCI1_0. The bits used to indicate short messages and the remaining bits in DCI1_0 are reserved bits.

[0125] In some embodiments, the remaining bits of DCI1_0 are used as a first field for information indication. Bits used to indicate paging scheduling information and TRS availability are designated as a third field. Based on this, DCI1_0 includes: a short message indicator, a first field, and a third field. The first field consists of reserved bits for DCI1_0, including the indication information described above. The third field includes indication information for paging scheduling and TRS availability, thus enabling the use of reserved bits in DCI1_0 to indicate other information and expand the indication dimension of DCI1_0.

[0126] The indication information for DCI1_0, which indicates the scheduling information for paging, and the availability of TRS can be found in the relevant protocol content, and will not be repeated here.

[0127] The method by which the first field of the network device configuration includes the aforementioned indication information can be as described in the previous implementation, and will not be repeated here.

[0128] It should be noted that the value of the short message indicator in DCI1_0 is 01. Since short messages are not indicated in DCI1_0, the first field can also indicate short messages, that is, it includes the indication information of short messages. The way the first field indicates short messages can also adopt the way that DCI1_0 indicates short messages as proposed by relevant protocols, which will not be elaborated here.

[0129] In another implementation, the short message indicator in DCI 1-0 is the first value, which is a non-reserved value, such as 10.

[0130] As shown in Figure 7, the value of the short message indicator in DCI1_0 is 10. The availability of short messages and TRS is indicated in DCI1_0, but the paging scheduling information is not indicated in DCI1_0. The bits used to indicate the paging scheduling information and the remaining bits in DCI1_0 are reserved bits.

[0131] In some embodiments, the remaining bits of DCI1_0 are used as the first field for information indication, and the bits used to indicate the availability of short messages and TRS are called the third field. Based on this, DCI1_0 includes: a short message indicator, a first field, and a third field. The first field occupies N bits of the reserved bits in DCI1_0, where N is greater than or equal to 1. Of course, the first field does not necessarily occupy all the reserved bits. The first field includes the indication information described above, and the third field includes the short message indication information and the TRS availability indication information, thus enabling the use of the reserved bits of DCI1_0 to indicate other information, thereby expanding the indication dimension of DCI1_0.

[0132] The method by which DCI1_0 indicates the indication information of short messages and the availability of TRS can be found in the relevant protocol content, and will not be repeated here.

[0133] The method by which the first field of the network device configuration includes the aforementioned indication information can be as described in the previous implementation, and will not be repeated here.

[0134] It should be noted that the value of the short message indicator in DCI1_0 is 01. Since paging scheduling information is not indicated in DCI1_0, the first field can also indicate paging scheduling information, i.e., it includes indication information of paging scheduling information. The way the first field indicates paging scheduling information can also adopt the method of indicating paging scheduling information in DCI1_0 proposed by relevant protocols, which will not be elaborated here.

[0135] In another implementation, the short message indicator in DCI 1-0 is the first value, which is a non-reserved value, such as 11.

[0136] As shown in Figure 8, the value of the short message indicator in DCI1_0 is 11. Paging scheduling information, TRS availability indication, and short messages are all indicated in DCI1_0. The remaining bits in DCI1_0 are reserved bits.

[0137] In some embodiments, the remaining bits of DCI1_0 are used as the first field for information indication. The bits used to indicate paging scheduling information, TRS availability indication, and short message information are the third field. Based on this, DCI1_0 includes: a short message indicator, a first field, and a third field. The first field consists of reserved bits for DCI1_0, occupying N bits (N is greater than or equal to 1), and does not necessarily occupy all reserved bits. The first field includes the indication information described above. The third field includes indication information for paging scheduling information, TRS availability indication information, and short message indication information. This allows the reserved bits of DCI1_0 to be used to indicate other information, thus expanding the indication dimension of DCI1_0.

[0138] DCI1_0 indicates paging scheduling information. The availability of TRS and the method of short messages can be found in the relevant protocol content, which will not be repeated here.

[0139] The method by which the first field of the network device configuration includes the aforementioned indication information can be as described in the previous implementation, and will not be repeated here.

[0140] When the value of the short message indicator in DCI1_0 is 11, since DCI1_0 is used to indicate paging scheduling information, TRS availability indication and short messages, DCI1_0 only has 8-M or 6-M reserved bits, where M refers to the number of bits occupied by the TRS availability indication information.

[0141] When the reserved bits of DCI1_0 are sufficient for information indication, DCI1_0 includes a first field that includes indication information. In some embodiments, the number of reserved bits of DCI1_0 is greater than or equal to a third value, which is the number of bits required for the information indication function.

[0142] When the reserved bits of DCI1_0 are insufficient for information indication, the first field can include indication information in the following two ways.

[0143] Method 1: The network device restricts the value of M so that the reserved bits meet the requirements of the information indication function. In some embodiments, the network device restricts M to be less than or equal to a second value so that the reserved bits of DCI1_0 are sufficient for information indication.

[0144] According to relevant protocols, the availability indication information of TRS can occupy 1, 2, 3, 4, 5, or 6 bits. Network devices support the use of reserved bits for information indication. Since the reserved bits include at least 1 bit, when DCI1_0 has 8-M reserved bits, the availability indication information of TRS, i.e., M, should be less than or equal to 6. When DCI1_0 has 6-M reserved bits, the availability indication information of TRS, i.e., M, should be less than or equal to 5.

[0145] Method 2: The network device reduces the amount of indication information included in the first field.

[0146] When the reserved bits of DCI1_0 are sufficient for information indication, the first field may include indication information associated with the first function, the first message, and / or the first common channel. If the reserved bits of DCI1_0 are insufficient for information indication, the first field may include a portion of the indication information associated with the first function, the first message, and / or the first common channel.

[0147] In one implementation, the number of objects indicated by the first field is reduced. For example, the first field may only include indication information associated with the first function, or the first field may only include indication information associated with the first message, or the first field may include indication information associated with only the first common channel, or the first field may include one or a combination of one or a few indication information associated with functions, one or a few indication information associated with messages, and one or a few indication information associated with common channels.

[0148] In another implementation, the number of objects indicated by the first field is not reduced, but the associated indication information of the objects indicated by the first field is reduced. For example, when the reserved bits of DCI1_0 are sufficient for information indication, the indication information associated with a common channel included in the first field is item X. When the reserved bits of DCI1_0 are insufficient for indicating item X, the first field indicates item Y of item X, where Y is less than X. Of course, the reserved bits of DCI1_0 are sufficient to indicate item Y.

[0149] In another implementation, the number of objects indicated by the first field and the associated indication information of the objects indicated by the first field are both reduced. Since the reserved bits in DCI1_0 are very few, including only 1 bit, 2 bits, etc., the amount of indication information included in the first field can be further reduced.

[0150] It should be noted that when the reserved bits of DCI1_0 are insufficient for information indication, that is, when the number of reserved bits of DCI is less than the third value, the indication information included in the first field can also be used to indicate that the indication function of the first field is invalid, or that the indication function of the first field is unavailable, and the indication function of the first field is deactivated.

[0151] For example, the reserved bits of DCI1_0 include 1 bit, and the first field includes 1 bit. If the value of 1 bit is 0, the indication function of the first field in DCI1_0 is invalid; if the value of 1 bit is 1, it can be used to indicate that the indication information associated with the first function, the first message and / or the first common channel is valid.

[0152] In summary, after expanding the indication dimensions of DCI 1-0 information, the different values ​​of the DCI 1-0 short message indicator represent the information indicated by DCI 1-0 as shown in Table 2.

[0153] Table 2 DCI 1-0 Short Message Indicators

[0154] It is understandable that the implementation of DCI by network devices can be found in the relevant protocol content, and will not be repeated here.

[0155] S202. The terminal parses the short message indicator and parses the first field based on the short message indicator.

[0156] After receiving the DCI, the terminal can parse the value of the short message indicator in the DCI, and further parse the first field based on the value of the short message indicator to obtain the information indicated by the first field.

[0157] Taking DCI 1-0 as an example, unlike the original DCI 1-0 where the short message indicator is 00, DCI 1-0 is reserved and not used to indicate other information. In the technical solution where the terminal receives DCI 1-0, parses its short message indicator as 00, and then discards the DCI 1-0 without further parsing, in the technical solution of this application, after the terminal receives DCI 1-0 and parses its short message indicator as 00, it can further parse the content of the first field in DCI 1-0 to determine the information indicated by the first field.

[0158] In this embodiment of the application, the reserved fields of DCI are used to include indication information, which expands the dimensions of DCI indication information and realizes the function of fully and efficiently utilizing DCI to indicate information.

[0159] Figure 9 illustrates an example of the composition of a communication device provided in an embodiment of this application. This communication device can be a terminal, including but not limited to mobile phones, smart wearable devices (such as smartwatches), and other electronic devices.

[0167] In addition, an operating system runs on top of the aforementioned components. Examples include iOS, Android, and Windows. Applications can be installed and run on this operating system.

[0168] Figure 10 illustrates another example of the composition of a communication device provided in an embodiment of this application. This communication device can be a network device, such as a satellite. Figure 10 shows a simplified schematic diagram of a network device. The network device includes: at least one processor 210, at least one memory 220, at least one transceiver 230, at least one network interface 240, and one or more antennas 250.

The antenna 250 is connected to the transceiver 230. The network interface 240 is used to enable a network element to connect to other communication devices through a communication link. For example, the network interface 240 may include a network interface between a network element and network elements in the core network, such as an S1 interface.

The ASIC with the integrated processor may be packaged separately or together with other circuits. In addition to the cores for executing software instructions to perform calculations or processing, the processor may further include necessary hardware accelerators, such as field-programmable gate arrays (FPGAs), programmable logic devices (PLDs), or logic circuits that implement dedicated logic operations.

In addition, the transmitter Tx in transceiver 230 is also used to receive modulated digital baseband signals or IF signals from processor 210, convert the modulated digital baseband signals or IF signals into RF signals, and transmit the RF signals through one or more antennas 250. Specifically, the receiver Rx can selectively perform one or more stages of downmixing and analog-to-digital conversion on the radio frequency signal to obtain a digital baseband signal or a digital intermediate frequency (IF) signal.
