Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication party and a device.

Background

For some services, the interval between the two services is longer, and the communication data packet is smaller. In order to achieve the purposes of saving energy and reducing signaling overhead, LTE release-16 decides to standardize a mechanism for transmitting data on predefined resources, that is, communication that does not require dynamic downlink control information (downlink control information, DCI) scheduling, and thus may also be referred to as scheduling-free transmission. The uplink scheduling-free transmission process comprises the following steps: when the terminal equipment has uplink data to be transmitted, the network equipment is not required to dynamically schedule the uplink of the terminal equipment, and the terminal equipment performs uplink transmission on the pre-configured transmission resources according to a pre-defined transmission mode.

After the transmission of the preconfigured uplink resources (preconfigured uplink resource transmission, PUR) is successful or failed, the network device sends a successful receipt Acknowledgement (ACK) or a failed transmission acknowledgement (NACK) or the like to the user. In addition, since the wireless channel environment dynamically changes with time, transmission parameters preconfigured by the network device may not be applicable during PUR transmission, such as Timing Advance (TA), data repetition times, power control information, and the like. The configuration information of PUR also needs to be updated continuously.

Currently, the network device feeds back to the user configuration update information such as a PUR successful transmission acknowledgement or a PUR failed transmission acknowledgement, and TA and repetition number by using user-specific downlink control information (downlink control information, DCI). However, since the number of bits occupied by ACK/NACK and update configuration information is relatively small, there is a certain waste of resources to use the user specific DCI for feedback.

Disclosure of Invention

The embodiment of the application provides a communication method and equipment, which are used for solving the problem that a base station uses user specific DCI to feed back ACK/NACK and updates configuration information in the prior art, so that certain resource waste exists.

Compared with the prior art that the ACK/NACK is fed back and the configuration information is updated through the user specific DCI, in the embodiment of the invention, the first equipment can feed back the first information to the second equipment through the user group control information, so that the first information of a plurality of second equipment can be carried in one message, further network resources can be saved, and the power consumption of the user is reduced.

When the second device adjusts the parameter value of the first parameter to the target amount, the parameter value of the first parameter may be adjusted to a product of the adjustment granularity indicated by M bits and the number indicated by M-M bits; alternatively, when the second device adjusts the parameter value of the first parameter by the adjustment amount based on the current parameter value, the parameter value of the first parameter may be adjusted by the product of the adjustment granularity indicated by the M bits and the number indicated by the M-M bits based on the current parameter value.

For example, the terminal device may also be a personal communication services (personal communication service, PCS) phone, cordless phone, session initiation protocol (session initiation protocol, SIP) phone, wireless local loop (wireless local loop, WLL) station, personal digital assistant (personal digital assistant, PDA), or the like.

For example, the network device may be a base station (base transceiver station, BTS) in a global system for mobile communications (global system for mobile communication, GSM) or code division multiple access (code division multiple access, CDMA), a base station (NodeB) in wideband code division multiple access (wideband code division multiple access, WCDMA), an evolved base station (evolutional Node B, eNB or e-NodeB) in LTE, a new radio controller (new radio controller, NR controller), a gNode B (gNB) in a 5G system, a centralized unit, a new radio base station, a remote radio module, a micro base station, a relay, a distributed unit, a receiving point (transmission reception point, TRP) or a transmission point (transmission point, TP), or any other wireless access device, but the embodiments of the present application are not limited thereto. A network device may cover 1 or more cells.

Referring to fig. 1, a communication system provided in an embodiment of the present application includes a network device and six terminal devices, i.e., UE1 to UE6. In the communication system, UE1 to UE6 may transmit uplink data to a network device, and the network device may receive the uplink data transmitted by UE1 to UE6. In addition, UEs 4 to 6 may constitute one sub-communication system. The network device may send downlink information to UE1, UE2, UE3, UE5, and UE5 may send downlink information to UE4, UE6 based on a device-to-device (D2D) technology. Fig. 1 is merely a schematic diagram, and the type of the communication system, and the number, type, and the like of devices included in the communication system are not particularly limited.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems. For some services, in order to reduce resource overhead, reduce data transmission delay and save energy, as shown in fig. 2, the services may be transmitted on predefined resources, that is, dynamic downlink control information (downlink control information, DCI) scheduling is not required, and the user transmits signals on preconfigured resources. Such transmissions are called configured scheduled transmissions, also known as preconfigured resource transmissions or preconfigured resource non-scheduled transmissions or non-scheduled transmissions. In particular, the pre-configured resources may be pre-configured uplink resources. The uplink scheduling-free transmission or pre-configured uplink resource transmission (preconfigured uplink resource transmission, PUR) process is as follows: when the terminal equipment has uplink data to be transmitted, the network equipment is not required to dynamically schedule the uplink of the terminal equipment, and the terminal equipment performs uplink transmission on the pre-configured transmission resources according to a pre-defined transmission mode.

After the transmission success or failure of the preconfigured uplink resource transmission (preconfigured uplink resource transmission, PUR), the network device may send a successful receipt Acknowledgement (ACK) or a failed transmission acknowledgement (NACK) or the like to the user. In addition, in the pre-configuration transmission process, the user only has uplink signal transmission on the PUR resource, and the PUR configuration information of the user transmission signal is pre-configured by the base station and not dynamically notified by the base station. However, the wireless channel environment dynamically changes with time, so that the transmission parameters preconfigured by the network device may not be applicable during PUR transmission, such as Timing Advance (TA), data repetition times, power control information, etc. The configuration information of PUR also needs to be updated continuously.

Currently, the network device feeds back to the user configuration update information such as a PUR successful transmission acknowledgement or a PUR failed transmission acknowledgement, and TA and repetition number by using user-specific downlink control information (downlink control information, DCI). However, since the user specific DCI generally occupies more than 30 bits, and the number of bits occupied by the ACK/NACK and the update configuration information is relatively small, and generally occupies less than 10 bits, there is a certain waste of resources in using the user specific DCI for feedback.

The embodiment of the application provides a communication method and device, which are used for solving the problem of resource waste when network equipment feeds back a PUR successful transmission response or a PUR failed transmission response and PUR configuration update information to a user in the prior art. The method and the device are based on the same inventive concept, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

The plural references in the embodiments of the present application refer to two or more.

It should be appreciated that in the description herein, the words "first," "second," and the like are used solely for distinguishing between the descriptions and not necessarily for indicating or implying a relative importance or order.

Referring to fig. 3, a flow chart of a communication method is provided. The method can be applied to the communication system shown in fig. 1, and the method comprises the following steps:

s301, the first device determines first information corresponding to at least two second devices, where the first information includes configuration update information (or may also be referred to as parameter update information or may also be referred to as configuration reconfiguration information or may also be referred to as parameter reconfiguration information). Wherein the configuration update information (or parameter update information or configuration reconfiguration information or parameter reconfiguration information) may be configuration update information of the pre-configured resource. The configuration update information includes update information for at least one of the following parameters (or may also be referred to as configuration update information including at least one of the following parameters): TA, number of data channel repetitions, number of control channel repetitions, deactivation information, paging (paging) information, transport block size information, modulation and coding scheme, verification time of TA. In addition, the configuration update information may further include update information of the power control information, or the configuration update information may further include the power control information.

The first device may be a network device, and the second device may be a terminal device. Alternatively, the second device may be a network device, and the first device may be a terminal device. Alternatively, the first device may be a device with transmitting capabilities and the second device may be a device with receiving capabilities.

In a specific implementation, the configuration update information included in the first information may also be other parameters or configuration information of other parameters.

In addition, the first information may further include information indicating a preconfigured resource transmission state including one of: successful transmission, unsuccessful transmission, scheduled retransmission, retransmission in preconfigured resources, transmission of specific sequences, initiation of random access, advanced data transmission (early data transmission, EDT), initiation of non-contention random access. Alternatively, it is also understood that the first information may also indicate a successful or unsuccessful transmission or scheduled retransmission or retransmission in a preconfigured resource or a transmission of a specific sequence or an initiation of random access or EDT or a non-contention random access.

In a specific implementation, the first information may also only include information indicating a transmission state of the preconfigured resource.

As an exemplary illustration, the first information may include only paging information, and the paging message is used to indicate whether the user is paged, or the paging message may be used to indicate whether random access or data advance transmission is initiated. For example, a 1 bit of control information indicates the paging message, the first information indicates that the second device is paged when in a first state (e.g., the 1 bit is a 1 value), and the first information indicates that the second device is not paged when in a second state (e.g., the 1 bit is a 0 value). Of course, the second device may be indicated as being paged when the bit value is 0, and the second device may not be indicated as being paged when the bit value is 1. In addition, the control information may indicate a paging message (e.g., 2 bits, etc.) through a plurality of bits, which is not particularly limited herein. The manner in which the control information indicates the paging message through a plurality of bits is similar to the manner in which the control information indicates the paging message through 1 bit, and the description thereof will not be repeated.

In summary, the first information may include one or more of the following: TA, data channel repetition number, control channel repetition number, deactivation information, paging information, power control information, transport block size (transmission block size, TBS) information, modulation and coding scheme (modulation and coding scheme, MCS), authentication time of TA, information indicating successful transmission, information indicating unsuccessful transmission, information indicating scheduled retransmission, information indicating retransmission in preconfigured resources, information indicating transmission of a specific sequence, information indicating initiation of random access, information indicating EDT, information indicating initiation of non-contention random access.

In this embodiment, TA is timing advance information used when the second device transmits uplink data in the preconfigured resource transmission.

The number of data channel repetitions may be the number of uplink data channel (physical uplink shared channel, PUSCH) repetitions and the number of downlink data channel (physical downlink shared channel, PDSCH) repetitions.

The control channels in the control channel repetition number comprise a physical downlink control channel (physical downlink control channel, PDCCH) or a machine type communication physical downlink control channel (machine type communication physical downlink control channel, MPDCCH) or an enhanced physical downlink control channel (enhanced physical downlink control channel, ePDCCH) or a narrowband physical downlink control channel (narrowband physical downlink control channel, NPDCCH). Other types of control channels are also possible and are not particularly limited herein.

The deactivation information may also be a deactivation information indicating that the second device does not transmit information on the first resource or does not transmit uplink information using the first resource. It is also understood that the first resource is deactivated or indicates that the first resource is in a deactivated or deactivated state. An exemplary first resource is a preconfigured resource.

The power control information may be a target amount or an adjustment amount of power, or may be a size of a power ramp (ramp step). The target amount here means that the second device takes the power information as the transmission power transmission information; the adjustment amount is to determine the transmission power based on the last transmission power and the adjustment amount, that is, to add or subtract the adjustment amount based on the last transmission power (e.g., if the adjustment amount is negative, then the adjustment amount is subtracted based on the last transmission power; if the adjustment amount is positive, then the adjustment amount is added based on the last transmission power); the climbing step refers to the adjustment granularity (or unit) of the power adjustment of the second device each time, and the second device adjusts the current transmission power according to the climbing step and the last transmission power. The step of climbing can also be understood as the amount of each adjustment of the transmission power.

The authentication time of the TA is the time the second device authenticates the TA. For example, the first device may indicate, through the first information, that the second device performs TA verification not earlier than x time units before the first resource start position, or the first device may indicate, through the first information, that the second device has earliest (or farthest, or maximum) verification time, which may be a subframe, a frame, a slot, ms, a symbol, s or us, etc., before the first resource start position by x time units, which is not specifically limited. It may also be understood that the first device indicates, through the first information, a first period of time during which the second device performs TA verification, where the period of time starts x time units before the first resource start time and ends y time units of the first resource, where x > y, where y may be equal to 0 or greater than 0. In a specific implementation, the first device may indicate the authentication time of the TA through other information independent of the first information, that is, the authentication time of the TA may be separately transmitted.

In a specific implementation, the first device may further send first indication information to the first device, where the first indication information is used to indicate a starting position of the user search space. Optionally, the first information activates or deactivates the information. For example, the search space is located at a first location when discontinuous transmission or skip transmission (skip) is enabled, and at a second location when discontinuous transmission or skip transmission (skip) is disabled. Further, when the search space is located at the first position, the control information may include deactivation information of the PUR. The control information may be user-specific control information or control information of a user group. The second device may determine whether to use the first location or the second location in a predefined manner.

The information indicating successful transmission may be a normal receipt acknowledgement ACK (Acknowledgement). The information indicating unsuccessful transmission may be that no reply NACK (Negative Acknowledgement) is normally received.

In some implementations, the first information may include only ACKs, or the first information may include only NACKs.

In other embodiments, the first device may not feed back an ACK to the second device when the second device transmits a particular sequence in the PUR. That is, the first information includes information indicating transmission of the specific sequence, or the first information may not include ACK/NACK when the first information is used to indicate transmission of the specific sequence.

For convenience of description, the embodiments of the present application will be described below taking ACK as information indicating successful transmission and NACK as information indicating unsuccessful transmission as an example.

S302, the first device sends control information, wherein the control information carries first information of at least two second devices. Correspondingly, the second device receives the control information sent by the first device.

S303, the second device determines first information corresponding to the second device based on the control information.

As a possible implementation manner, if the first information includes configuration update information of the pre-configured resource and information indicating a transmission state of the pre-configured resource. The positions of the information 1 and the information 2 of the same second device in the control information may be configured to be the same, for example, as shown in fig. 4, where the control information carries first information of UE1 to UE4, information 1-1, information 1-2, information 1-3, and information 1-4 are configuration update information of preconfigured resources of UE1 to UE4, and information 2-1, information 2-2, information 2-3, and information 2-4 are information indicating transmission states of preconfigured resources of UE1 to UE4, respectively.

Therefore, the configuration update information of the preconfigured resource of the second device and the index indicating the position of the information of the transmission state of the preconfigured resource at the position of the control information may be configured to be the same, for example, the positions of the information 1-1 and the information 2-1 of the UE1 are both the positions with the index of 1, and at this time, the notification can be performed by using one information, so that the signaling resource can be saved.

Or, the configuration update information of the preconfigured resource of the same second device and the information indicating the transmission state of the preconfigured resource may be configured differently at the position of the control information, for example, as shown in fig. 5, where the control information carries the first information of UE1 to UE4, and information 1-1, information 1-2, information 1-3, and information 1-4 are respectively the configuration update information of the preconfigured resource of UE1 to UE4, and are sequentially located at the first 4 positions of the control information. Information 2-1, information 2-2, information 2-3, and information 2-4 are information indicating the transmission state of the preconfigured resource of UE1 to UE4, respectively, and are sequentially located at the last 4 positions of the control information.

Therefore, the configuration update information of the preconfigured resource of the second device and the index indicating the position of the information of the transmission state of the preconfigured resource at the position of the control information may be configured to be different, for example, the position of the information 1-1 of the UE1 is the position with the index of 1, the position of the information 2-1 is the position with the index of 5, and at this time, the position of the information 1-1 and the position of the information 2-1 of the UE1 are respectively indicated by the two information, so that flexibility may be improved.

In a specific implementation, the positions, such as indexes (index) or bit positions, of the first information corresponding to the at least two second devices in the control information may be configured by the first device through higher layer signaling. Specifically, the first device may configure the positions of the first information corresponding to the at least two second devices in the control information in the following manner: for each second device, the first device sends second signaling to the second device, where the second signaling is used to indicate an index of a position of first information corresponding to the second device in the control message. Correspondingly, the second device receives the second signaling sent by the first device, so that the position of the first information corresponding to the second device in the control message is determined according to the second signaling. The second signaling may be a radio resource control (radio resource control, RRC) message or a medium access control element (media access control control element, MAC CE) message, for example. Taking the schematic diagram shown in fig. 4 as an example, the first device may configure the positions of the first information of UE1 to UE4 in the control information by using an RRC message or a MAC CE message to be the positions with indexes 1, 2, 3, and 4, respectively. Alternatively, taking the schematic diagram shown in fig. 5 as an example, the first device may configure, through an RRC message or a MAC CE message, that the positions of the configuration update information of the preconfigured resources of the UE1 in the control information are respectively the positions with the index of 1, and that the positions of the information indicating the transmission state of the preconfigured resources of the UE1 in the control information are respectively the positions with the index of 5.

Alternatively, the positions of the first information, such as index or bit positions, corresponding to the at least two second devices in the control information may be predefined. The second device may thus use the predefined index as an index of the position of the second device in the control information corresponding to the first information. For example, taking the schematic diagram shown in fig. 4 as an example, the index of the position of the first information of UE1 in the control information is 1. Taking the schematic diagram shown in fig. 4 as an example, the index of the position of the configuration update information of the preconfigured resource of UE1 in the control information is 1, and the index of the position of the information indicating the transmission state of the preconfigured resource in the control information is 5.

In some embodiments, when the first device sends the control information, the location index corresponding to the second device may be determined first, the first information corresponding to the second device is carried in the location corresponding to the index in the control information, and then the control information is sent.

Specifically, if the configuration update information of the preconfigured resource of the same second device and the information indicating the transmission state of the preconfigured resource can be configured to be the same in the control information, the first device can indicate the position of the first information of the second device in the control information through a second signaling. If the configuration update information of the preconfigured resource of the same second device and the information indicating the transmission state of the preconfigured resource can be configured to be different in the position of the control information, the first device can respectively indicate the position of the configuration update information of the preconfigured resource of the second device and the position of the information indicating the transmission state of the preconfigured resource in the control information through two second signaling.

Correspondingly, when the second device determines the first information corresponding to the second device based on the control information, a position corresponding to the index can be found in the control information, and then the first information is acquired at the position.

Specifically, if the configuration update information of the preconfigured resource of the same second device and the information indicating the transmission state of the preconfigured resource can be configured to be the same at the position of the control information, the second device may predefine an index, and acquire the first information at the position corresponding to the index after receiving the control information. If the configuration update information of the preconfigured resource of the same second device and the information indicating the transmission state of the preconfigured resource can be configured to be different in the position of the control information, the second device can predefine two indexes, and after receiving the control information, the configuration update information of the preconfigured resource and the information indicating the transmission state of the preconfigured resource are respectively obtained in the corresponding positions of the two indexes.

As a possible implementation manner, for the update information of the first parameter in the configuration update information, the first parameter is one or more of the following parameters: TA, number of data channel repetitions, number of control channel repetitions, power control information, transport block size information, and modulation and coding scheme. The update information of the first parameter may be a target amount of the first parameter or an adjustment amount of the first parameter. The adjustment amount may be positive or negative.

Thus, the second device can adjust the parameter value of the first parameter to the target amount; alternatively, the parameter value of the first parameter may be adjusted by the adjustment amount on the basis of the current parameter value.

In one exemplary illustration, M bits of the control information are used to indicate the update information of the first parameter, wherein M bits of the M bits are used to indicate the adjustment granularity of the update information, M-M bits of the M bits are used to indicate the target amount of the first parameter or the amount of adjustment in units of the adjustment granularity, M, M is an integer greater than 0, and M is less than M. For example, assuming that the adjustment granularity of the update information is 2 and the m-m bit indication value is (or takes on a value of) 5 by using the m-bit indication, the target amount or adjustment amount of the first parameter is 2×5=10.

Further, the second device may adjust the parameter value of the first parameter to a product of the adjustment granularity of the M-bit indication and the number of M-bit indications. Alternatively, the second device may adjust the parameter value of the first parameter by the product of the adjustment granularity of the M-bit indication and the number of M-M bit indications based on the current parameter value.

The first parameter may be, for example, specifically the power control information or the number of data channel repetitions or the number of control channel repetitions or TA.

Taking the first parameter as TA as an example, the control information may indicate the adjustment amount of TA by 3 bits, wherein the upper (or lower) bits are used to indicate the adjustment granularity, e.g. the upper bits having a value of 0 indicates that the adjustment granularity is 2 ^k1 *16Ts, where T _s The high order bit value of 1 means that the adjustment granularity is 2 for =1/(15000×2048) seconds ^k2 *16Ts, wherein k1 and k2 may be positive or negative numbers; the lower two bits are expressed as the number when the granularity is adjusted as a unit; according to the formula: TA (TA) _new ＝TA _old ++ (P-Q) G, wherein TA _new And TA _old The amounts after TA adjustment and before adjustment are respectively defined by P and Q, and G is the adjustment granularity; or the first parameter is indicated, and the TA adjustment amount is determined according to the first parameter and the granularity, for example, according to the formula: TA (TA) _new ＝TA _old ++ (P-Q) G, wherein TA _new And TA _old And respectively determining the quantity after TA adjustment and before adjustment, wherein P is determined according to a first parameter, Q is predefined, and G is the adjustment granularity.

For example, as shown in FIG. 6, 6 bits in the figure represent 6 bits carrying TA adjustment amount in the prior art, and the upper 0 of 3 bits of TA adjustment amount represents the adjustment granularity corresponding to the lower two bits of 6 bits as 16Ts and the lower two bits as 11, so the final TA adjustment amount is TA _new ＝TA _old 16Ts + (3-1). Alternatively, the upper 1 represents the adjustment granularity corresponding to the upper two of the 6 bits of 2 ⁴ *16Ts, the lower two bits are 11, so the final adjustment amount is TA _new ＝TA _old +(3-1)*2 ⁴ *16Ts。

In another exemplary illustration, M bits of the control information are used to indicate the update information of the first parameter, M bits of the M bits are used to indicate the first set, M-M bits of the M bits are used to indicate the update information of the first parameter in the first set, M are integers greater than 0, and M is less than M. Wherein, for example, the first set includes one or more values, and M-M bits in the M bits may indicate the adjustment amount or the target value of the first parameter by an index indicating a value in the first set, e.g., M-M bits indicate 3, and the second device may determine the first set according to the M bits, and then determine a third value in the first set as the adjustment amount or the target value of the first parameter according to the M-M bits.

Further, the first parameter may specifically be TBS or MCS. Wherein M bits of the M bits are used to indicate that the target value or adjustment amount of the TBS or MCS is in the first set, and M-M bits of the M bits are used to indicate the adjustment amount or target value of the TBS (or MCS) in the first set.

In yet another exemplary illustration, M bits of the control information are used to indicate update information of the first parameter, M bits are used to indicate update information of the first parameter in the second set, and M is an integer greater than 0. Wherein the second set may be configured for the first device via higher layer signaling. Specifically, the first device configures the second set by: the first device sends first signaling to the second device, the first signaling indicating the second set. And the second device determines the second set after receiving the first signaling sent by the first device.

Alternatively, the second set may be predefined. Thus, the second device may take the predefined set as the second set.

In this embodiment of the present application, the first signaling and the second signaling may be the same signaling, or may be different signaling, which is not specifically limited herein.

As a possible implementation, the cyclic redundancy check (cyclical redundancy check, CRC) of the control information is scrambled by a first scrambling code, which may be one of the following information: pre-configuring information radio network identification, user group radio network temporary identification, system information radio network temporary identification (system information radio network temporary identifier, SI-RNTI). I.e. the first device may employ a user group radio network temporary identity or SI-RNTI, and the first scrambling code may be a user specific RNTI (e.g. cell-RNTI) and the search space in which the control information is located is a cell common search space (common search space).

It should be noted that, if at least two second devices belong to the same user group, the first scrambling code is a user group wireless network temporary identifier.

Thus, the second device, upon receiving the control information, descrambles the Cyclic Redundancy Check (CRC) code of the control information using the first scrambling code. Wherein the first scrambling code may be that the first device configures the second device.

It should be noted that, in the embodiment of the present application, the preconfigured uplink resource (preconfigured uplink resource, PUR) is merely an exemplary naming, which is essentially that, by configuring the resource, the second device may perform uplink information transmission on the resource without the need of dynamic scheduling or downlink control information scheduling of the first device, and the resource may also be named as another name, for example, a configuration grant resource, and it should be understood that, if the configuration grant resource may also implement a function implemented by the preconfigured uplink resource in the embodiment of the present application, the configuration grant resource may also be understood as the preconfigured uplink resource in the embodiment of the present application.

For convenience of description, this transmission mode is collectively referred to as preconfigured resource transmission in the embodiments of the present application.

The retransmission of the pre-configured resource may refer to retransmission in the pre-configured uplink resource or in a part of the pre-configured uplink resource, i.e. dynamic scheduling information (such as DCI) is not needed for scheduling, but retransmission is performed through the pre-configured uplink resource, but the configuration information of the corresponding pre-configured resource may be reconfigured or updated through the dynamic scheduling information.

Scheduling retransmission refers to that the second device performs retransmission according to the scheduling information of the dynamic scheduling information (such as DCI) of the first device.

For example, the control information may be downlink control information in the LTE eMTC system, downlink control information of the NR system, and the like, which is not specifically limited herein.

For example, the first field may be a Flag field such as Flag format 6-0A/format 6-1A differentiation or a sounding reference signal request field such as sounding reference signal request, (SRS request).

Or, the second field and the third field in the first control information are used to indicate the third information.
