Description

Information notification method and device

Technical Field

The present invention relates to the field of mobile communications, and in particular, to a method and an apparatus for information notification.

Background

In a Long Term Evolution (LTE) system, a terminal device supports simultaneous access to two network devices, and this access manner is called Dual Connectivity (DC), where one network device is a primary network device and the other network device is a secondary network device. In the development and evolution process of a wireless communication system, an operator may simultaneously deploy a 5G New air interface (NR) system and a Long Term Evolution (LTE) system, and a terminal device also supports simultaneous Access to a network device of LTE and a network device of NR, because LTE is also called Evolved Universal Terrestrial Radio Access (E-UTRA), this Access mode is called Evolved Universal Terrestrial Radio Access and New air interface Dual Connectivity (EN-DC). In the EN-DC mode, the network device of the LTE is a primary network device, and the network device of the NR is a secondary network device, and certainly along with the evolution of the system, a new air interface and an evolved universal terrestrial radio access Dual connection (NR E-UTRA Dual Connectivity, NE-DC) may also be supported in the future, that is, the network device of the NR is a primary network device, and the network device of the LTE is a secondary network device.

For a wireless communication system, the Duplex mode may be mainly divided into a Frequency Division Duplex (FDD) mode and a Time Division Duplex (TDD) mode according to the difference of the Duplex mode, wherein for a wireless communication system operating in the TDD mode, the system usually includes only one operating Frequency band, so the Frequency band is also referred to as an unpaired Frequency band. For a system using unpaired frequency bands, in a certain period of time, in an area covered by the same network equipment, the whole working frequency band is only used for downlink communication or only used for uplink communication; for a wireless communication system operating in FDD mode, the system typically comprises two paired frequency bands for communication, one for downlink communication from network device to terminal device and the other for uplink communication from terminal device to network device.

Currently, a typical deployment mode is that NR is deployed in an unpaired frequency band in a TDD mode, such as a frequency band around 3.5GHz, and LTE is deployed in a paired frequency band in an FDD mode, such as a frequency band around 1.8 GHz. In this deployment scenario, a terminal device operating in the EN-DC mode operates in the FDD mode on the LTE side and in the TDD mode on the NR side.

In order to avoid the influence of cross modulation on the performance, and meanwhile, the influence is also limited by the capacity, the transmitting power and other factors of the terminal, for the terminal working under the EN-DC, the terminal only sends an uplink signal on one frequency point in the same time, namely when the terminal sends the uplink signal on NR, the terminal does not send the uplink signal on LTE, and vice versa.

In order to implement that the terminal device only transmits in one uplink of NR and LTE, the network device of LTE configures, for the terminal operating in DC mode, the same reference uplink and downlink configuration as that in the case where TDD-FDD carrier aggregation and TDD carrier is the primary carrier, as shown in table 1 below. The network device may configure the terminal with one of the 7 configurations in table 1, so that the terminal device transmits uplink signals only on a part of the LTE uplink subframe. For example, when the terminal is configured with the reference uplink and downlink configuration 0, the terminal device can only transmit uplink signals on

subframes

2, 3, 4, 7, 8, and 9, where the uplink signals include a PUCCH (Physical-layer uplink control channel), a PUSCH (Physical-layer uplink shared channel), a PRACH (Physical-layer random access channel), or an SRS (Sounding reference signal), and meanwhile, the terminal device cannot transmit any uplink signal on subframes 0, 1, 5, and 6 (i.e., the subframe labeled as "-" in the table). Meanwhile, the network device may also configure an offset value for the terminal, where the offset value ranges from 0 to 9, and is used to adjust the number of the uplink subframe that can be used by the terminal device. For example, when the terminal device configures the reference uplink/downlink configuration 1, the terminal device can only transmit uplink signals on subframes 2, 3, 7, and 8 originally, and if the terminal device is also configured with an offset value, if the offset value is 2, the subframes in which the terminal transmits uplink signals become

subframes

4, 5, 9, and 0.

TABLE 1

In the prior art, once a terminal device is configured with one of the uplink and downlink configurations in the above table, the terminal device can only transmit PUCCH on the uplink subframe corresponding to the uplink and downlink configuration, and for other uplink signals including PUSCH, PRACH, and SRS, the terminal device can only transmit in the uplink subframe for transmitting PUCCH.

According to the configuration in the above table, at least 4 subframes of the 10 subframes cannot be used for uplink transmission on the LTE side of the terminal. For the subframes configured by the LTE side and incapable of transmitting the uplink signal, the terminal does not necessarily transmit the uplink signal in the time period corresponding to the subframes on the NR side, which may cause the uplink resource of the terminal on the LTE side to be wasted and reduce the spectrum utilization rate of the network. As shown in fig. 1, the subframe correspondence relationship between LTE and NR, where "U" represents uplink, "D" represents downlink, and "X" represents a subframe that cannot be used for communication, and the terminal uses a subcarrier interval of 15kHz on the LTE side and a subcarrier interval of 30kHz on the NR side, it can be seen that the NR side performs only downlink reception in a time period corresponding to the LTE subframe included in a square frame, so that LTE should perform uplink transmission in the subframe, but the terminal cannot transmit an uplink signal in the subframe due to the limitation of the uplink and downlink configuration in the prior art, which results in resource waste.

Therefore, for a terminal working in an EN-DC mode, the resource allocation flexibility of uplink information on the LTE side is not sufficient when uplink single transmission is realized by using reference uplink and downlink allocation.

Generally, the conventional Communication system supports a limited number of connections and is easy to implement, however, with the development of Communication technology, the mobile Communication system will support not only conventional Communication but also, for example, Device-to-Device (D2D) Communication, Machine-to-Machine (M2M) Communication, Machine Type Communication (MTC), and Vehicle-to-Vehicle (V2V) Communication.

The embodiments of the present invention are described in conjunction with an access network device and a terminal device, where:

a terminal device may also be referred to as a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. The terminal device may be a Station (ST) in a WLAN, and may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle-mounted device, a wearable device, and a next-generation communication system, such as a terminal device in a fifth-generation communication (5G) Network or a terminal device in a future-evolution Public Land Mobile Network (PLMN) Network, and the like.

By way of example, and not limitation, in embodiments of the present invention, the terminal device may also be a wearable device. Wearable equipment can also be called wearable intelligent equipment, is the general term of applying wearable technique to carry out intelligent design, develop the equipment that can dress to daily wearing, like glasses, gloves, wrist-watch, dress and shoes etc.. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

Further, the access network device may be a network device or the like for communicating with the mobile device, and the access network device may be configured to provide wireless communication functionality for the terminal device. The access network devices may include various forms of macro base stations, micro base stations (also referred to as small stations), relay stations, access points, and the like. The Access network device may be an Access Point (AP) in a WLAN, a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB, NB) in WCDMA, or a gbb in NR system, an evolved Node B (eNB or eNodeB) in LTE, or a relay Station or an Access Point, or a vehicle-mounted device, a wearable device, a network device in a future 5G network, or a network device in a future evolved PLMN network, and the like. For convenience of description, in all embodiments of the present invention, the above-mentioned apparatus for providing a wireless communication function for a terminal device is collectively referred to as an access network device. In this application, a network device and an access network device are equivalent terms unless otherwise specified.

In addition, in this embodiment of the present invention, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a Small cell (Small cell), where the Small cell may include: urban cells (Metro cells), Micro cells (Micro cells), Pico cells (Pico cells), Femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services.

In addition, multiple cells can simultaneously work at the same frequency on a carrier in an LTE system or a 5G system, and under some special scenes, the concepts of the carrier and the cells can also be considered to be equivalent. For example, in a Carrier Aggregation (CA) scenario, when a secondary Carrier is configured for a UE, a Carrier index of the secondary Carrier and a Cell identity (Cell identity) of a secondary Cell operating on the secondary Carrier are carried at the same time, in which case, the Carrier and the Cell may be considered to be equivalent in concept, for example, it is equivalent that the UE accesses one Carrier and one Cell.

In the embodiment of the present invention, the frequency domain resources used by the network device and the terminal device for wireless communication (e.g., uplink transmission or downlink transmission) are frequency domain resources used based on a contention mechanism.

For example, the network device and/or the terminal device may detect whether a frequency domain resource with a certain bandwidth (e.g., 20MHz) is currently in an idle state, or whether the frequency domain resource is used by other devices.

If the frequency domain resource is in an idle state, or the frequency domain resource is not used by other devices, the network device and/or the terminal device may use the frequency domain resource to perform communication, for example, perform uplink transmission or downlink transmission.

If the frequency domain resource is not in an idle state, or the frequency domain resource is already used by other devices, the network device and/or the terminal device cannot use the frequency domain resource.

It should be noted that, in the embodiment of the present invention, the specific method and process of the contention mechanism may be similar to those in the prior art, and a detailed description thereof is omitted here to avoid redundancy.

By way of example and not limitation, in the embodiment of the present invention, the frequency domain resource used by the communication system 100 (or the frequency domain resource used by the network device and the terminal device based on the contention mechanism) may also be a licensed spectrum resource, that is, the communication system 100 of the embodiment of the present invention is a communication system capable of using a licensed frequency band, and each communication device (network device and/or terminal device) in the system 100 may use the frequency domain resource of the licensed frequency band in a contention manner.

In this embodiment of the present invention, a physical channel (physical channel) is specifically used for transmission of data information and/or control information, for example, the physical channel includes one or a combination of the following: PUSCH (Physical uplink Shared Channel), PUCCH (Physical uplink Control Channel), PDCCH (Physical Downlink Control Channel), EPDCCH (Enhanced-Physical Downlink Control Channel), PCFICH (Physical Control Format Indicator Channel), PHICH (Physical hybrid ARQ Indicator Channel), PDSCH (Physical Downlink Shared Channel), etc., or channels that have the same function and are different names, such as a Control Channel or a data Channel introduced in short TTI transmission.

The time unit in the embodiment of the present invention may be a subframe, a slot, a micro slot, a symbol, and the like. It should be noted that L different wireless communication systems have different definitions for subframes and slots, and the time unit here may be a subframe, a slot, a sub-slot (sub-slot), and a symbol of LTE, or a subframe, a slot, a micro-slot, and a symbol of NR system.

It should be understood that, in the embodiment of the present invention, "when …", "if" and "if" all refer to that the terminal device or the access network device performs corresponding processing under a certain objective condition, and are not limited time, and do not require a certain judgment action when the terminal device or the access network device performs, nor do they mean that there are other limitations.

Fig. 2a, 2b, 3a and 3b are schematic diagrams of a wireless communication system according to an embodiment of the present invention. The wireless communication system comprises network equipment and terminal equipment, downlink data transmission and uplink data transmission exist between the network equipment and the terminal equipment, and the network equipment can be communicated with the plurality of terminal equipment. The terminal device works in a dual connection mode of LTE and NR, that is, the terminal device simultaneously accesses to a network device of LTE and a network device of NR. The network devices include network devices of LTE and network devices of NR. As shown in fig. 2a, in one implementation, the network device of LTE and the network device of NR may be deployed on the same site. When the network device of the LTE and the network device of the NR are deployed on the same site, the network device of the LTE and the network device of the NR may share the same hardware device or may use different hardware devices. As shown in fig. 3a, in another implementation, the network device of LTE and the network device of NR may also be deployed on different sites.

As shown in fig. 2b, the network device includes: the network equipment comprises an LTE processor, an NR processor and a transceiver, wherein an area served by the network equipment is a cell. The transceiver may be 1 antenna or multiple antennas. The terminal device includes: an LTE processor, an NR processor, and a transceiver.

As shown in fig. 3b, the network device may include an LTE network device and an NR network device, wherein the LTE network device includes: a processor and a transceiver. The NR network device includes: a processor and a transceiver. The terminal device includes: an LTE processor, an NR processor, and a transceiver.

Network devices transmit information to terminal devices over a forward link (also referred to as the downlink) and receive information from terminal devices over a reverse link (also referred to as the uplink). For example, in a Frequency Division Duplex (FDD) system, the forward link may use a different Frequency band than the reverse link. As another example, in a Time Division Duplex (TDD) system and a Full Duplex (Full Duplex) system, the forward link and the reverse link may use a common frequency band.

At a given time, the network device or the terminal device may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting device may obtain (e.g., generate, receive from other communication devices, or save in memory, etc.) a number of data bits to be transmitted over the channel to the wireless communication receiving device. Such data bits may be included in a transport block (or transport blocks) of data, which may be segmented to produce a plurality of code blocks.

The first time unit may be used for transmitting at least one signal of PUCCH, PUSCH, PRACH, or SRS.

In this embodiment, the time domain unit is a time domain resource unit configured to be used for uplink signal transmission. A time domain unit contains multiple time units. For example, for an FDD system, the time domain resource units configured for uplink transmission may be all uplink subframes on an uplink carrier, or may be part of the uplink subframes; for a TDD system, the time domain resource unit configured for uplink transmission may be a subframe determined to be uplink according to the uplink and downlink configuration information. The time domain unit and the time unit in this embodiment are used for uplink signal transmission, or may also be referred to as an uplink time domain resource and an uplink time unit.

In one embodiment, the terminal device accesses the first network device through a first network access technology and accesses the second network device through a second network access technology. It should be understood that the first network device and the second network device herein are network devices that employ different radio access technologies. For example, the first network device is a network device adopting an LTE access technology, and the second network device is a network device adopting an NR access technology.

S402: the first network device determines second indication information, where the second indication information is used to indicate a second time unit configured for the terminal device by the first network device and used to transmit at least one signal of a PUSCH, a PRACH, or an SRS, and the second time unit includes at least one time unit except the first time unit in the time domain unit.

The terminal device may transmit at least one of a PUSCH, PRACH, or SRS on the second time unit, but may not transmit the PUCCH on time units other than the first time unit in the second time unit.

Optionally, the second time unit indicated by the second indication information is at least one time unit in the time domain units.

Optionally, the second time unit indicated by the second indication information is at least one time unit in the time unit except the first time unit.

FIG. 5 is a diagram of a relationship between time cells, where a time cell includes a plurality of time cells. Referring to fig. 5, the first time unit indicated by the first indication information is a time unit with padding, and the second time unit indicated by the second indication information includes at least one of the time units without padding. Alternatively, the second time unit indicated by the second indication information is at least one of the time units without padding, but the second time unit indicated by the second indication information does not include the time unit in the first time unit. In this way, the second indication information configures a time element, which is not configured to transmit at least one of the PUSCH, the PRACH, or the SRS, in the first indication information, so that the at least one of the PUSCH, the PRACH, or the SRS can be transmitted, but the second time element is not used for transmitting the PUCCH.

The execution sequence of step S401 and step S402 may be arbitrary or may be executed simultaneously.

S403: the first network equipment sends first indication information and second indication information to the terminal equipment, and the terminal equipment receives the first indication information and the second indication information.

The first indication information and the second indication information may be sent in a single message or may be sent in two messages respectively.

Optionally, the first indication information and the second indication information may be carried in configuration information dedicated to the terminal and sent to the terminal device by the first network device.

S404: and the terminal equipment determines a time unit for transmitting at least one signal of PUSCH, PRACH or SRS according to the second indication information.

In one embodiment, the terminal device determines a second time unit according to the second indication information, where the second time unit is a time unit used by the terminal device to transmit at least one of a PUSCH, a PRACH, or an SRS.

Optionally, the terminal device may jointly determine, according to the first indication information and the second indication information, a time unit capable of transmitting at least one of a PUSCH, a PRACH, or an SRS.

In one embodiment, the terminal device jointly determines, according to the first indication information and the second indication information, that a time unit capable of transmitting at least one of a PUSCH, a PRACH, or an SRS is a union of the first time unit and the second time unit. For example, if the first time unit is subframe a, subframe B and subframe C, and the second time unit is subframe C and subframe D, the terminal device determines that at least one signal of PUSCH, PRACH or SRS can be transmitted as subframe a, subframe B, subframe C and subframe D.

S405: and the terminal equipment determines a time unit for transmitting the PUCCH according to the first indication information.

The execution sequence of step S404 and step S405 may be arbitrary or may be executed simultaneously.

In one embodiment, the time domain unit is a frame and the time domain unit is a subframe.

In order to improve the utilization rate of uplink resources of a terminal operating in an EN-DC mode on an LTE side, an embodiment of the present invention adds, on the LTE side, indication information to indicate subframes that can be used for uplink transmission in subframes that are configured by reference uplink and downlink and that cannot be used for uplink transmission, so that the terminal can transmit a PUSCH/PRACH/SRS on the subframes but cannot transmit a PUCCH.

In the embodiment of the invention, the first network equipment is added with the indication information to indicate the time units which can be used for uplink transmission in the time units which are configured by the reference uplink and downlink and cannot be used for uplink transmission, so that the terminal can transmit the PUSCH/PRACH/SRS in the time units but cannot transmit the PUCCH. The terminal equipment working in the EN-DC mode can have more uplink subframes on the first network equipment side, and compared with the prior art, the frequency spectrum efficiency of uplink transmission can be improved.

Further, in the above method, the terminal device cannot transmit uplink signals in time units other than the first time unit and the second time unit in the time domain unit.

The specific form of the second indication information in the above embodiment may be one of the following forms.

In one embodiment, the second indication information comprises a field with N bits, wherein N is a positive integer greater than or equal to 1; each bit corresponds to one time unit, when the bit is in a first state value, the corresponding time unit can transmit at least one signal of PUSCH, PRACH or SRS, and when the bit is in a second state value, the corresponding time unit cannot transmit at least one signal of PUSCH, PRACH or SRS.

In one implementation, N is equal to the number of time units included in the time domain unit, and the fields of N bits correspond to the time units included in the time domain unit one to one.

For example, the first indication information is a field including 10 bits, and each bit of the field corresponds to a subframe in a frame. Optionally, the ith bit corresponds to a subframe numbered as (i-1), where i is a positive integer from 1 to 10. For example, when the ith bit is 0, the subframe (i-1) is indicated as a subframe in which the uplink signal cannot be transmitted, and when the ith bit is 1, the subframe (i-1) is indicated as a subframe in which the uplink signal can be transmitted, which may be the reverse of this.

In this way, the terminal device may determine the time unit capable of transmitting at least one of the PUSCH, PRACH, or SRS directly from the second indication information.

By the configuration of the implementation mode, independent configuration can be carried out on any time unit in the time domain unit, and the flexibility of configuration is guaranteed to the maximum extent.

In another implementation, N is equal to the number of time units included in the time domain unit minus the number of time units included in the first time unit; and the fields of the N bits correspond to the time units except the first time unit in the time domain unit one by one.

For example, for at least one of configurations 0 to 6, the value of N is equal to the number of subframes that cannot be used for transmitting uplink signals in the configuration. Illustratively, when the first indication information indicates configuration 0, the value of N is equal to 4; when the first indication information indicates configuration 1, the value of N is equal to 6; when the first indication information indicates configuration 2, the value of N is equal to 8; when the first indication information indicates configuration 3, the value of N is equal to 7; when the first indication information indicates configuration 4, the value of N is equal to 8; when the first indication information indicates configuration 5, the value of N is equal to 9; when the first indication information indicates configuration 6, the value of N is equal to 5.

In this way, the terminal device may jointly determine a time unit capable of transmitting at least one of the PUSCH, the PRACH, or the SRS according to the first indication information and the second indication information.

By the configuration of the implementation mode, the signaling overhead of the second indication information can be reduced on the premise of ensuring the flexibility of time unit configuration.

In another embodiment, the second indication information is a field capable of indicating M different states, where M is a positive integer greater than or equal to 1; wherein the M is equal to the number of time unit combinations of the time unit except the first time unit in the time domain unit, which can be used for transmitting at least one signal of PUSCH, PRACH or SRS.

One of the M states in this field corresponds to a subframe configuration.

For example, the value of M is 4, and when the first indication information indicates configuration 0, the 4 states indicated by the second indication information respectively correspond to the subframe states shown in fig. 6a to 6f, as shown in fig. 6a, where the subframes denoted by "X" and "Y" are subframes in which the second indication information is configured to be unable to transmit uplink signals, and the subframe denoted by "Y" is a subframe in which the first indication information is configured to be able to transmit uplink signals (including at least one of PUSCH, PRACH, or SRS). In addition, when the network device does not transmit the first indication information to the terminal device, the terminal device determines a subframe capable of transmitting the uplink signal and/or a subframe incapable of transmitting the uplink signal according to the configuration indicated by the second indication information. When the second indication information indicates configuration 1, 2 states among 4 states indicated by the first indication information are available, as shown in fig. 6 b. When the second indication information indicates configuration 2, any one of the 4 states indicated by the first indication information indicates the subframe configuration shown in fig. 6 c. When the first indication information indicates configuration 3, 2 states among the 4 states indicated by the second indication information are available, as shown in fig. 6 d. When the first indication information indicates configuration 4, any one of the 4 states indicated by the second indication information indicates the subframe configuration shown in fig. 6 e. When the first indication information indicates configuration 5, any one of the 4 states indicated by the second indication information indicates the subframe configuration shown in fig. 6 f.

It should be noted that, when the number of the statuses in the second indication information is greater than the number of the available time unit configurations, according to the above method, only a part of the statuses in the second indication information may be used for indicating the time unit configurations, and the remaining statuses are reserved statuses, or multiple statuses in the second indication information may correspond to one time unit configuration, which is not limited in this embodiment.

By configuring in this way, a trade-off can be achieved between flexibility of time cell configuration and overhead of second indication information signaling.

In another embodiment, the first indication information is a field capable of indicating 2 different states.

On the basis of the above embodiment, the second indication information needs to indicate 4 states at most, i.e. 2 bits of indication field are needed for indication. In order to reduce the overhead of the indication field, only state 0 and state 1 in fig. 6a are reserved in this embodiment, and the second indication information only needs to indicate one of state 0 and state 1. For example, specifically, when the first indication information indicates configuration 0, the second indication information indicates the subframe configuration corresponding to state 0 or state 1 in fig. 6 a. When the first indication information indicates configuration 1, the second indication information indicates a subframe configuration corresponding to state 0 or state 1 in fig. 6 b. When the first indication information indicates configuration 2, the second indication information indicates the subframe configuration in fig. 5 c. When the first indication information indicates configuration 2, any one of the 2 states indicated by the second indication information indicates the subframe configuration shown in fig. 6 c. When the first indication information indicates configuration 3, the 2 states of the second indication information correspond to state 0 and state 1 in fig. 6d, respectively. When the first indication information indicates configuration 4, any one of the 2 states indicated by the second indication information indicates the subframe configuration shown in fig. 6 e. When the first indication information indicates configuration 5, any one of the 2 states indicated by the second indication information indicates the subframe configuration shown in fig. 6 f.

By the implementation mode, the signaling overhead of the second indication information can be reduced to the maximum extent.

In another embodiment, the time domain units are K frames, where K is an integer greater than 1; the time unit is one subframe. The number of the frame in the LTE system is from 0 to 1023, so the value of K may be 1024, and of course, other values smaller than 1024 or values larger than 1024 may be also possible. The second indication information in the above embodiment may be in one of the following specific forms.

In one implementation, the second indication information indicates that at least one subframe of K1 frames of the K frames may transmit at least one signal of a PUSCH, a PRACH, or an SRS, where K1 is an integer greater than or equal to 1 and less than or equal to K, e.g., K1 may be equal to K/2, K/3, K/4, K/5, and so on.

Optionally, the second indication information includes at least one of first sub information or second sub information, where the first sub information is used to indicate K1 frames in the K frames, and the K1 sub frames are used to transmit at least one signal of a PUSCH, a PRACH, or an SRS, where K1 is an integer greater than or equal to 1 and less than or equal to K. The second sub-information is used for indicating at least one subframe in one frame, and the at least one subframe is used for transmitting at least one signal in PUSCH, PRACH or SRS.

The second indication information may include the first sub information and the second sub information, and may also include one of the first sub information and the second sub information. And when the second indication information comprises the first sub information and does not comprise the second sub information, indicating that all uplink subframes in K1 frames of the K frames can transmit at least one signal of PUSCH, PRACH or SRS. When the second indication information includes the second sub information and does not include the first sub information, indicating that at least one subframe of the K frames can transmit at least one signal of PUSCH, PRACH, or SRS. When the second indication information includes first sub information indicating K1 frames among the K frames and second sub information indicating at least one sub frame among one frame among the K1 frames.

Optionally, the first sub information may indicate a part of frames among the K frames. For example, the K1 frames indicated by the second indication information may be even numbered frames, odd numbered frames, or frames numbered modulo 4 i (i ═ 0, 1, 2, or 3) of the K frames, and are not limited herein.

Optionally, the second sub information indicates at least one subframe in the one frame, where a specific implementation manner of the second sub information is similar to a specific implementation manner of the second indication information in other embodiments in this application, for example, similar to an implementation manner of the second indication information in the embodiment corresponding to fig. 4.
