TECHNICAL FIELD

Embodiments of the present disclosure relates to the technical field of communication, and in particular, to a method for transmitting information, a terminal device and a network device.

BACKGROUND

In an existing wireless communication system, such as a Long Term Evolution (LTE) system, time-frequency resources taken by downlink control information in a single scheduling unit are fixed. Taking a sub-frame as a scheduling unit for example, the first few symbols in each sub-frame are used to transmit the downlink control information, and the downlink control information spans the entire system bandwidth in the frequency domain.

Future wireless communication systems, such as 5G, are committed to supporting higher system performance and need to support multiple service types, different deployment scenarios, and a wider spectrum range.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present disclosure will be clearly and completely described in the following with reference to the accompanying drawings.

The technical solution of the embodiments of the present disclosure can be applied to various communication systems, for example, a Global System of Mobile communication (“GSM”) system, a Code Division Multiple Access (“CDMA”) system, a Wideband Code Division Multiple Access (“WCDMA”) system, General Packet Radio Service (“GPRS”), a Long Term Evolution (“LTE”) system, LTE Frequency Division Duplex (“FDD”) system, LTE Time Division Duplex (“TDD”), a Universal Mobile Telecommunication System (“UMTS”), a worldwide interoperability for microwave access communication system, a future evolution of the Public Land Mobile Network (PLMN), or a future 5G system.

FIG. 1 is a schematic diagram of a wireless communication system applicable in the embodiments of the present disclosure. The wireless communication system 100 can include at least one network device 110. The network device 100 can be a device in communication with a terminal device. Each network device 100 can provide communication coverage for a particular geographic region and can communicate with terminal devices (e.g., UEs) located within the coverage area. The network device 100 can be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, or can be a base station (NodeB, NB) in a WCDMA system, or can be an evolved base station in an LTE system (Evolutional Node B, eNB or eNodeB), or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device can be a relay station, an access point, an in-vehicle device, a wearable device, or a network side device in a future 5G network or a network device in a future evolved PLMN.

The wireless communication system 100 also includes a plurality of terminal devices 120 located within the coverage of the network device 110. The terminal device 120 can be mobile or fixed. The terminal device 120 can refer to an access terminal, user equipment (User Equipment, UE), a subscriber unit, a subscriber station, a mobile station, a mobile platform, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, and a user agent or a user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to wireless modems, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved PLMN, and the like.

Optionally, the wireless communication system 100 can further include other network entities, such as a network controller, a mobility management entity, and the like, and the embodiment of the present disclosure is not limited thereto.

FIG. 2 is a schematic diagram of a resource area of a conventional sub-frame. As shown in FIG. 2, in the prior art, the resource area for transmitting downlink control information is fixed. The terminal device can detect its own first downlink control information at a fixed location. This method has low flexibility and is not conducive to improving system performance.

For example, a conventional system has a bandwidth of 20 MHz, and the terminal device detects the first downlink control information in the entire system bandwidth of the first three symbols of the sub-frame. In future wireless communication systems (e.g., 5G), the bandwidth of the system can be extended to 80 MHz, 160 MHz or even 320 MHz. If the network device still sends downlink control information according to the full bandwidth, it will cause a large waste of resources. In addition, transmitting downlink control information on a fixed resource area can also cause unnecessary interference of control information between cells.

In view of the above, an embodiment of the present disclosure provides a method for transmitting information, in which the first resource area for transmitting downlink control information is not fixed, and the network device can determine different first resource areas, and the method has a higher flexibility and applicability, which is conducive to improve system performance.

Hereinafter, a method for transmitting information according to an embodiment of the present disclosure will be described in detail with reference to FIG. 3.

It should be understood that FIG. 3 illustrates the detailed communication steps or operations of the method, but these steps or operations are merely examples, and other embodiments of the present application can also perform other operations or variations of the various operations in FIG. 3. Moreover, the various steps in FIG. 3 can be performed in a different order than that shown in FIG. 3, and it is possible to perform only a part of the operations in FIG. 3.

FIG. 3 is a schematic flowchart of a method for transmitting information according to an embodiment of the present disclosure. The method 200 can be applied to the wireless communication system 100 as described in FIG. 1, but the embodiment of the present disclosure is not limited thereto. As shown in FIG. 3, the method 200 includes the following steps.

In S210, the network device sends first indication information to the terminal device according to a first resource area for transmitting downlink control information; correspondingly, and the terminal device receives the first indication information sent by the network device.

It should be understood that the first resource area can be understood as a resource area taken by the network device when transmitting downlink control information. The network device will use the first resource area to transmit downlink control information.

The number of the first resource areas can be one or more. For example, the first resource area can include a first resource area P₁and a first resource area P₂,

The frequency domain resources included in the first resource area can take the entire system bandwidth or can take a part of the system bandwidth. For example, assuming that the system bandwidth is 80 MHz, the frequency domain resources included in the first resource area P₁can be 0-20 MHz.

Optionally, the frequency domain resources in the first resource area can be continuous or discontinuous. For example, assuming that the number of the first resource areas is two, the system bandwidth is 80 MHz, the frequency domain resource in the first resource area P_target1is 0-20 MHz, and the frequency domain resource in the first resource area P_target2is 30-50 MHz. That is, the first resource area includes frequency domain resources of 0-20 MHz and 30-50 MHz.

Optionally, the time domain resources included in the first resource area can be continuous or discontinuous. For example, assuming that the number of the first resource areas is two, the time domain resource in the first resource area P_target1can be a symbol numbered 0. The time domain resource in the first resource area Ptarget2 can be a symbol numbered 2. That is, the time domain resource included in the first resource area are symbols numbered 0 and 2.

The first indication information is used by the terminal device to receive the first downlink control information sent by the network device. The first indication information can be carried in system information or dedicated control signaling (or channel). For example, the first indication information can be carried in Radio Resource Control (RRC) layer signaling, Medium Access Control (MAC) layer signaling, or physical layer signaling.

It should be noted that the related description of the time-frequency resource of the first resource area is applicable to the resource area of the embodiments of the present disclosure. For example, a second resource area or a resource area corresponding to the transmission mode (described later) includes a frequency domain resource that may be part of the system bandwidth.

In S220, the network device sends downlink control information on the first resource area for transmitting downlink control information. Correspondingly, the terminal device receives, according to the first indication information, the first downlink control information sent by the network device.

It should be understood that the first downlink control information is downlink control information for the terminal device. The first indication information can be directed to a certain terminal device, and the first indication information can also be directed to a plurality of terminal devices.

Optionally, the method can further include the following.

In a possible solution, the first indication information can be directed to a certain terminal device. For example, the first indication information can be directed to a terminal device UE₁, and the first indication information can be used to indicate a resource area (for example, the number of the sub-frame, the number of the symbol, and the location of the frequency domain resource) taken by downlink control information I₁(downlink control information I₁is downlink control information for the terminal device UE₁). The terminal device UE₁can determine the time-frequency resource where the downlink control information I₁is located after receiving the first indication information.

In another possible solution, the first indication information can be directed to a plurality of terminal devices (optionally, the plurality of terminal devices can be all terminal devices covered by the network device). For example, the first indication information can be used to indicate the first resource area. Each terminal device of the plurality of terminal devices can detect downlink control information belonging to itself on the first resource area according to the first indication information. For example, the terminal device UE₁can detect the downlink control information I₁on the first resource area according to the first indication information, and a terminal device UE₂can detect downlink control information I₂on the first resource area according to the first indication information.

It should be noted that, if the first indication information is directed to a plurality of terminal devices, the first resource area is a time-frequency resource in one scheduling unit. The scheduling unit can refer to a time domain resource unit for one data transmission of the terminal device scheduled by the network device. For example, one scheduling unit can correspond to one or more sub-frames, slots, or mini-slots and the like in the time domain.

For example, if the scheduling unit is a sub-frame, the time domain resources included in the first resource area are symbols numbered 0, 1, and 2, and the frequency domain resource is 0-20 MHz. The network device can send downlink control information on the first resource area of each scheduling unit of the at least one scheduling unit. For example, the network device sends downlink control information on the first resource area of the sub-frame numbered 1, and downlink control information on the first resource area of the sub-frame numbered 2.

The first resource area in the embodiment of the present disclosure is not fixed, and the network device can determine different first resource areas according to actual conditions. Therefore, the network device sends the first indication information to the terminal device before sending the downlink control information on the first resource area. The terminal device first receives the first indication information, and then receives the first downlink control information sent by the network device according to the first indication information.

Therefore, the first resource area of the embodiment of the present disclosure has high flexibility compared to the prior art in which resource area for transmitting downlink control information is fixed and unchanged. The network device can determine different first resource areas according to actual conditions. The frequency domain resources (broadband) and time domain resources (symbols) included in the first resource area can be flexibly determined according to actual conditions. After determining the first resource area, the network device can send the first indication information and then send the downlink control information, so that the terminal device can receive the first downlink control information according to the first indication information. The method of the embodiment of the present disclosure can better adapt to satisfy the requirement of flexibly configuring the first resource for transmitting downlink control information in a large-bandwidth system, and can improve system efficiency and reduce system interference.

Optionally, the network device can send the first indication information according to the first resource area in various situations.

For example, the network device can, based on a timer timing, periodically send the first indication information to the terminal device according to the first resource area for transmitting the downlink control information.

For another example, when the first resource area changes, the network device sends the first indication information according to the resulted first resource area after the change.

Optionally, the method S200 can include the following steps.

In S201, the network device can determine a first resource area for transmitting downlink control information.

Specifically, if the first resource area currently determined by the network device is different from the first resource area for transmitting the downlink control information previously, the network device determines that the first resource area has changed. In this case, the first indication information can be used to indicate that the first resource area has changed, and can also be used to indicate a change result of the first resource area.

It should be noted that, in the embodiment of the present disclosure, the first resource area for transmitting downlink control information refers to the resulted first resource area after the change. In other words, if the first resource area changes, the network device sends downlink control information on the resulted first resource area after the change.

Hereinafter, the embodiment of the present disclosure will be described by taking a change in the first resource as an example. Unless otherwise specified, the first resource area described below is the resulted first resource area after the change.

The first indication information in the embodiment of the present disclosure is described in detail by taking the first indication information as an example for a plurality of terminal devices. Optionally, the first indication information can include the following situations.

(I) The first indication information is used by the terminal device to determine the first resource area.

That is, optionally, the method 200 can include the following.

In S201, the terminal device determines the first resource area according to the first indication information. Optionally, the first indication information can include the following:

(1) The first indication information is used to indicate the first resource area.

Specifically, after receiving the first indication information, the terminal device can directly learn about the first resource area.

FIG. 4 is a schematic diagram of an example of a method for transmitting information according to an embodiment of the present disclosure. As shown in FIG. 4, it is assumed that the number of the first resource areas is three, and the first resource area includes a first resource area P_target1, a first resource area P_target2, and a first resource area P_target3. The first indication information can be used to indicate the first resource area P_target1, the first resource area P_target2, and the first resource area P_target3.

(2) The first indication information is used by the terminal device to determine a first transmission mode from a plurality of transmission modes, wherein the resource area corresponds to the first transmission mode is the first resource area.

The plurality of transmission modes can be previously agreed between the network device and the terminal device, or can be previously configured, or can be configured by the network device with configuration information. Each of the plurality of transmission modes corresponds to a different resource area. Optionally, the network device can send, to the terminal device, first configuration information, wherein the first configuration information is used to configure the multiple transmission modes.

For example, the plurality of transmission modes includes a transmission mode T₁, a transmission mode T₂, and a transmission mode T₃. The resource area corresponding to the transmission mode T₁includes symbols numbered 0, 1, and 2 on the time domain resource, and includes a bandwidth of 55-75 MHz on the frequency domain resource (corresponding to the symbol numbered 0), a bandwidth of 30-50 MHz on the frequency domain resource (corresponding to the symbol numbered 1), and a bandwidth of 5-25 MHz on the frequency domain resource (corresponding to the symbol numbered 2). The resource area corresponding to the transmission mode T₂includes symbols numbered 0, 1, and 2 on the time domain resource, and includes a bandwidth of 30-50 MHz on the frequency domain resource. The resource area corresponding to the transmission mode T₃includes symbols numbered 0, 1, and 2 on the time domain resource, and includes a bandwidth of 5-25 MHz on the frequency domain resource.

Specifically, the terminal device can determine the first transmission mode from the plurality of transmission modes according to the first indication information, and determine the resource area corresponding to the first transmission mode as the first resource area. The first indication information can include at least the following.

(2a) The first indication information is used to indicate the first transmission mode.

Specifically, after receiving the first indication information, the terminal device can directly learn about the first transmission mode, and determine the resource area corresponding to the first transmission mode as the first resource area. The first indication information can be used to indicate the sequence number of the first transmission mode.

Still referring to the example described above in which the plurality of transmission modes includes the transmission mode T₁, the transmission mode T₂, and the transmission mode T₃, the first indication information can be used to indicate the transmission mode T₁, and the terminal device determines the transmission mode T₁from the plurality of transmission modes after receiving the first indication information, that is, the transmission mode T₁is the first transmission mode.

For example, the first indication information can be used to indicate the sequence number of the first transmission mode.

(2b) The first indication information is used to indicate an initial resource area of the first resource area for transmitting downlink control information. The initial resource area for each of the plurality of transmission modes is different. That is, the initial resource areas corresponding to different transmission modes are different.

Still referring to the example described above in which the plurality of transmission modes includes the transmission mode T₁, the transmission mode T₂, and the transmission mode T₃, the time domain resource included in the initial resource area corresponding to the transmission mode T₁is a symbol numbered 0, and the frequency domain resource is a bandwidth of 55-75 MHz; the time domain resource included in the initial resource area corresponding to the transmission mode T₂is a symbol numbered 0, and the frequency domain resource is a bandwidth of 30-50 MHz; and the time domain resource included in the initial resource area corresponding to the transmission mode T₃is a symbol numbered 0, and the frequency domain resource is a bandwidth of 5-25 MHz. Assuming that the time domain resource included in the initial resource area of the first resource area indicated by the first indication information is a symbol numbered 0, and the frequency domain resource is a bandwidth of 55-75 MHz, the terminal device can determine, according to the first indication information, a transmission mode T₁from the plurality of transmission modes.

Optionally, the initial resource area corresponding to the transmission mode can be specified according to the time domain resource and/or the frequency domain resource. For example, it can be agreed that the resource area where the first symbol is located is the initial resource area.

Optionally, if the first indication information is used to indicate an initial resource area of the first resource area, and the terminal device determines that the initial resource area of the first resource area is not used for transmission of downlink control information by detecting the initial resource area of the first resource area, the terminal device can determine that the scheduling unit does not perform downlink control information transmission. The terminal device can continue to detect the first downlink control information on the subsequent scheduling unit.

FIG. 5 is another schematic diagram of a method for transmitting information according to an embodiment of the present disclosure. As shown in FIG. 5, the first indication information is used to indicate an initial resource area P_target1of the first resource area, and the terminal device can determine the remaining two first resource areas according to the initial resource area of the first resource area. Specifically, the terminal device can determine the first transmission mode from the plurality of transmission modes according to the first indication information, and determine the remaining two first resource areas according to the first transmission mode.

It should be noted that different resource areas can include at least two situations: one is that there is no overlap between resource areas, that is, there is no duplicate time-frequency resources; another is that there is a partial overlap between resource areas, which is not limited in the embodiments of the present disclosure.

Optionally, after receiving the first indication information, and before receiving second indication information, the terminal device can receive the first downlink control information by detecting the first downlink control information on the first resource on each scheduling unit.

Specifically, the second indication information is used to indicate that the first resource area has changed or the second indication information is used to indicate a change result of the first resource area.

For example, the terminal device can determine the first resource area according to the first indication information. The “first resource area determined according to the first indication information” can be referred to as “first resource area A”.

The terminal device can detect the first downlink control information on the first resource area A of each scheduling unit until the terminal device receives the second indication information. In other words, after receiving the first indication information (or determining the first resource area A), and before receiving the second indication information, the terminal device can detect the first downlink control information on the first resource area A of each scheduling unit.

As shown in FIG. 3 to FIG. 5, if the terminal device receives the second indication information, the terminal device can determine the first resource area according to the second indication information. The “first resource area determined according to the second indication information” can be referred to as a “first resource area B”. After receiving the second indication information, the terminal device can detect the first downlink control information on the first resource area B of each scheduling unit until the terminal device receives the next indication information. For the description of the second indication information, reference can be made to the description of the first indication information, which will not be repeated herein.

In (2b), the initial resource areas of each of the plurality of transmission modes are different. At this time, the terminal device can determine the first transmission mode according to the first indication information.

If the initial resource areas corresponding to at least two of the plurality of transmission modes are the same, the terminal device has to determine the first transmission mode through other manner.

For example, assuming that the plurality of transmission modes are K transmission modes, and the initial resource areas corresponding to L transmission modes are the same as the initial resource area of the first resource area indicated by the first indication information. The terminal device can detect the first downlink control information on the second resource area corresponding to the L transmission modes. Further, the terminal device can also determine the second resource area in the first resource area by detecting downlink control information on the second resource area corresponding to the L transmission modes. The terminal device can select, in the L transmission modes, J (1 custom character JL) transmission modes having the second resource area the same as the second first resource area in the first resource area. If J=1, the transmission mode is determined to be the first transmission mode, and the first downlink control information is detected on the resource area corresponding to the first transmission mode. If J custom character 2, the terminal device can continue to select the transmission mode until the first transmission mode is determined.

It should be noted that, in (I), the first indication information can be understood as resource information of the first resource area. The content indicated by the first indication information is related to the first resource area. The first resource area (specific time-frequency resource) used by the network device to transmit downlink control information can be indicated (or configured) through the indication information (for example, first indication information). The terminal device can determine all or part of the first resource area through the first indication information.

(II) The first indication information is used to indicate that the first resource area has changed.

FIG. 6 is a schematic diagram of still another example for transmitting downlink control information according to an embodiment of the present disclosure. As shown in FIG. 6, after receiving the first indication information, the terminal device determines that the first resource area has changed, and it will be wrong if the terminal device still detects the first downlink control information on the previous first resource area. Therefore, the terminal device receives the first downlink control information by detecting the first downlink control information on all or part of the second resource area for transmitting downlink control information according to the first indication information.

The second resource area for transmitting the downlink control information can be agreed between the network device and the terminal device, can be previously configured, or can be configured through configuration information.

For example, the network device and the terminal device can previously configure a second resource area for transmitting downlink control information by using subscription information, factory information, and initialization information.

For another example, the network device can send second configuration information to the terminal device, wherein the second configuration information is used to configure a second resource area for transmitting downlink control information.

It should be noted that the first configuration information and the second configuration information in the embodiment of the present disclosure can be sent through two messages, or can be sent through one message, which is not limited herein.

Alternatively, configuration information (e.g., first configuration information and/or second configuration information) can be carried in system information or in dedicated signaling.

For convenience of explanation, “the second resource area for transmitting downlink control information” can be referred to as a “dedicated resource area”. The dedicated resource area can be used to transmit downlink control information. In the process of actually transmitting downlink information, the network device can transmit downlink control information on all or part of a dedicated resource area. The dedicated resource area used can be the first resource area in the embodiment of the present disclosure.

Optionally, if the first indication information is used to indicate that the first resource area has changed, the terminal device receiving the first downlink control information by detecting the first downlink control information on all or part of the second resource area for transmitting downlink control information according to the first indication information may include the following two implementations.

First Implementation

The terminal device can detect the first downlink control information on the dedicated resource area.

Specifically, assuming that the dedicated resource area includes P₁-P₉, after receiving the first indication information, the terminal device receives the first downlink control information by detecting the first downlink control information on the P₁-P₉.

Further, the terminal device can determine the first resource area by detecting downlink control information on the dedicated resource area.
