UTRA and E-UTRA technologies are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE-Advanced (LTE) -A) is a newer version of UMTS using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). UMB is described in documents from an organization called "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used for the wireless networks and wireless access technologies mentioned above, as well as other wireless networks and wireless access technologies. For clarity, certain aspects of the technology are described below for LTE or LTE-A (or collectively referred to as "LTE/-A"), and such LTE/-A terminology is used in many of the descriptions below.

It should be noted that the wireless communication network may include multiple base stations capable of supporting communication of multiple user equipments. The user equipment can communicate with the base station over the downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the user equipment, and the uplink (or reverse link) refers to the communication link from the user equipment to the base station.

A user device (eg, a cell phone or smart phone) can utilize a wireless communication system to transmit and receive data for two-way communication. The user equipment may include a transmitter for data transmission and a receiver for data reception. For data transmission, the transmitter can modulate the transmit Local Oscillator (LO) signal with data to obtain a modulated Radio Frequency (RF) signal, and amplify the modulated RF signal to obtain proper transmission. The RF signal is output at the power level and the output RF signal is transmitted to the base station via the antenna. For data reception, the receiver can obtain the received RF signal via an antenna, amplify and downconvert the received RF signal with the received LO signal, and process the downconverted signal to recover the data transmitted by the base station.

The user equipment can support communication with multiple wireless systems of different Radio Access Technology (RAT) (eg, LTE/TE-A and NR). Each wireless system may have certain characteristics and requirements to efficiently support simultaneous communication of wireless systems utilizing different RATs. User equipment may include mobile stations, terminals, access terminals, subscriber units, stations, and the like. The user equipment can also be a cellular phone, a smart phone, a tablet computer, a wireless modem, a personal digital assistant (PDA), a handheld device, a laptop computer, a smartbook, a netbook, a cordless phone, a wireless local loop (wireless Local loop, WLL) site, Bluetooth device, and more. The user equipment may be capable of communicating with the wireless system, and may also be capable of receiving signals from a broadcast station, one or more satellites in a Global Navigation Satellite System (GNSS), or the like. The user equipment may support one or more RATs for wireless communication, such as GSM, WCDMA, cdma2000, LTE/LTE-A, 802.11, and the like. The terms "radio access technology", "RAT", "radio technology", "air interface" and "standard" are often used interchangeably.

User equipment can support carrier aggregation, and carrier aggregation is operation on multiple carriers. Carrier aggregation can also be referred to as multi-carrier operation. A carrier can refer to a range of frequencies that are used for communication and can be associated with certain characteristics. For example, a carrier may be associated with system information and/or control information describing operations on the carrier. A carrier may also be referred to as a component carrier (CC), a frequency channel, a cell, and the like. A frequency band can include one or more carriers. Illustratively, each carrier can cover up to 20 MHz. The user equipment can be configured with up to 5 carriers in one or two frequency bands. The user equipment may include multiple receivers to simultaneously receive multiple downlink signals at different frequencies. These multiple downlink signals may be transmitted by one or more base stations on multiple carriers at different frequencies for carrier aggregation. Each receiver may receive one or more downlink signals transmitted to the user equipment on one or more carriers. A UE operating in a carrier aggregation scenario is configured to aggregate certain functions of multiple carriers, such as control and feedback functions, on the same carrier, which may be referred to as a primary carrier or a primary component carrier (PCC). ). The remaining carriers supported by the primary carrier are referred to as associated secondary carriers or secondary component carriers (SCCs). The primary carrier is sent by the primary cell. The secondary carrier is sent by the secondary cell. In some embodiments, there may be multiple primary carriers. In addition, the secondary carrier can be added or removed without affecting the basic operation of the UE. In carrier aggregation, control functions may be aggregated from at least two carriers onto one carrier to form a primary carrier and one or more associated secondary carriers. A communication link can be established for the primary carrier and each secondary carrier. The communication can then be controlled based on the primary carrier. In carrier aggregation, the user equipment may also send a UE capability information message indicating the supported frequency band and carrier aggregation bandwidth class to the serving base station. Depending on the UE capabilities, the serving base station can configure the UE using an RRC connection reconfiguration procedure. The RRC connection reconfiguration procedure allows the serving base station to add and remove secondary cells (currently up to four secondary cells) of the serving base station transmitting on the secondary carrier, and to modify the primary cell of the serving base station transmitting on the primary carrier. During handover, the serving base station may use the RRC Connection Reconfiguration procedure to add and remove secondary cells at the target primary cell. The serving base station can activate or deactivate the data transmission of the secondary cell using the Activate/Deactivate MAC Control element. Currently, the UE monitors the Master Information Block (MIB) and the System Information Block SIB from the primary cell. The primary cell is responsible for transmitting the MIB of the secondary cell and some SIBs to the UE. The primary cell sends a secondary cell MIB and some SIBs by using a radio resource configuration common secondary cell (RadioResourceConfigCommonSCell) information element and a radio resource dedicated secondary cell (RadioResourceDedicatedSCell) information element. In some embodiments of the present invention, the primary carrier or the primary component carrier may be configured as a first spectrum, and the first spectrum may be a licensed spectrum; the associated secondary carrier or secondary component carrier may be configured as a second spectrum, The second spectrum is an unlicensed spectrum.

It should be noted that in the LTE/LTE-A system, the uplink/downlink carriers adopt Single-Carrier Frequency-Division Multiple Access (SC-FDMA)/OFDM and Cyclic Prefix (CP) respectively. ). In the 5G standard, for example, the uplink and downlink carriers can be unified, that is, both uplink and downlink adopt OFDM and CP. In another example, the RB in the 5G may be configured as follows, one resource block includes 12 subcarriers, the subcarrier spacing is based on 15 kHz, and the subcarrier spacing may be N (N=2^n) times of 15 kHz, or It can be fixed to a subcarrier spacing of 75 kHz. Specifically, the bandwidth of the traditional LTE cell working in the frequency band is composed of RBs, and the RBs have fixed subcarrier spacing and symbol length respectively. For example, under normal CP, the size in the frequency domain is 180 kHz (ie, 12 15 kHz subcarriers). Interval), including 7 symbols in the time domain, the length of one symbol is approximately equal to 71.5us. In the next generation of 5G mobile communication technologies (for example, in the NR system), different subcarriers may no longer have a fixed subcarrier spacing and a fixed symbol length (which may be dynamically changed) based on the traffic type. To distinguish it from the RB concept in the traditional LTE system, the NR system newly defines the concept of "numerology" (reference value), which mainly includes subcarrier spacing, CP length and TTI length. Currently, the NR system defines three service types, namely eMBB, URLLC, and mMTC. The "numerology" types of different service types may also be different, meaning that different types of subcarrier spacing, CP length, or TTI length may be different. Illustratively, it can be defined that next generation mobile communications will support a single carrier bandwidth of up to 100 MHz. The size of one resource block RB in the frequency domain becomes 900 KHz (ie, 12 75 KHz subcarrier intervals), and 0.1 ms is supported in the time domain. The length of one radio frame is 10 ms, but consists of 50 subframes, each of which has a length of 0.2 ms. It should be noted that the signal type applicable to the NR service described in this document may refer to a configuration including at least one of related parameters such as a carrier interval, a CP length, and a TTI length.

The embodiments of the present invention can be applied to an LAA system that uses unlicensed spectrum resources (such as a spectrum of 5 GHz) with the aid of the spectrum of a Long Term Evolution (LTE) system. It should be noted that the description of a specific network architecture in the following embodiments of the present invention is only an example (for example, LTE/LTE-A), and should not be construed as limiting. The method and apparatus disclosed by the present invention are equally applicable to a network architecture of a subsequent evolution (e.g., next generation 5G).

Figure 1 shows the system architecture diagram of the LTE system. The description of each network element and interface is as follows:

Mobility Management Entity (MME) / Serving Gateway (Serving) GateWay, S-GW): The MME is a key control node in the LTE of the 3rd Generation Partnership Project (3GPP). It belongs to the core network element and is mainly responsible for the signaling processing part, that is, the control plane function, including the connection. Incoming control, mobility management, attach and detach, session management functions, and gateway selection. The S-GW is an important network element of the core network in the 3GPP LTE. It is mainly responsible for the user plane function of user data forwarding, that is, routing and forwarding of data packets under the control of the MME. eNB: An eNodeB (eNB) may be a station that communicates with a user equipment UE, and may also be referred to as a base station, a Node B, an access point, and the like. Each eNB can provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to such a particular geographic coverage area of an eNB and/or such a particular geographic coverage area of an eNB subsystem serving the coverage area, depending on the context in which the term is used. The eNB is mainly responsible for radio resource management, quality of service (QoS) management, data compression, and encryption on the air interface side. To the core network side, the eNB is mainly responsible for forwarding control plane signaling to the MME and forwarding user plane service data to the S-GW. The eNB may provide communication coverage for macro cells, pico cells, femto cells, and/or other types of cells. A macro cell typically covers a relatively large geographic area (e.g., a range of several kilometers in radius) and may allow unrestricted access by UEs having subscriptions to services of the network provider. A pico cell typically covers a relatively small geographic area and may allow unrestricted access by UEs having subscriptions to services of the network provider. A femto cell typically also covers a relatively small geographic area (eg, a home) and may provide restricted access (eg, a closed user group) with UEs associated with the femto cell in addition to unrestricted access. (UE in the Closed Subscriber Group, CSG), UE of the user in the home, etc.). The eNB of the macro cell may be referred to as a macro eNB. An eNB of a pico cell may be referred to as a pico eNB. And, the eNB of the femto cell may be referred to as a femto eNB or a home eNB.

UE: The UE is a device that accesses the network side through the eNB in LTE, and may be, for example, a handheld terminal, a notebook computer, or other device that can access the network. When the UE needs to transmit uplink data on a specific channel (for example, physical uplink shared channel, English: Physical Uplink Shared Channel, PUSCH for short), the UE needs to inform the eNB that the uplink data needs to be transmitted, and the eNB knows that the UE needs to transmit. After the upper and lower data, uplink data scheduling is performed for the UE.

S1 interface: is a standard interface between the eNB and the core network. The eNB is connected to the MME through the S1-MME interface, and is used for control signaling transmission; the eNB is connected to the S-GW through the S1-U interface, and is used for transmission of user data. The S1-MME interface and the S1-U interface are collectively referred to as an S1 interface.

The X2 interface is a standard interface between the eNB and the eNB, and is used to implement interworking between the base stations.

Uu interface: The Uu interface is a radio interface between the UE and the base station eNB, and the UE accesses the LTE network through the Uu interface.

The uplink resource scheduling method in the embodiment of the present invention is mainly applied to the information exchanged between the UE and the Uu interface of the base station eNB, and the UE reports the channel state indication information to the eNB, where the channel state indication information is used to indicate that the current uplink channel of the UE is idle/ In the non-idle state, the eNB may schedule uplink resources allocated to the first user equipment according to the channel state indication information. It should be noted that the uplink resource may include a time-frequency resource location, a duration of occupying resources, and the like.

FIG. 2 is a flowchart of an uplink resource scheduling method according to an embodiment of the present disclosure, where the uplink resource scheduling method includes:

Step S201: Allocate an uplink resource to the first user equipment.

Specifically, the base station may allocate the uplink resource to the first user equipment in advance, or allocate the uplink resource to the first user equipment when the first user equipment requests the uplink scheduling from the base station, which is not specifically limited herein. The uplink resource is a physical resource used by the first user equipment to perform uplink data transmission, for example, an uplink subframe or a resource block in an uplink subframe.

Step S202: Receive channel state indication information reported by the first user equipment.

Specifically, the channel status indication information is indication information used to indicate that the uplink channel of the user equipment is currently in an idle/non-idle state. In a specific implementation, the channel state indication information may be multiplexed with the existing uplink control information (UCI, Uplink Control Information) for transmission, or may be carried in a preset new uplink control information format for transmission, which is not specifically limited herein. .

The channel state indication information is specifically generated by the first user equipment monitoring the corresponding uplink channel to obtain the state of the uplink channel.

Step S203: Perform scheduling on an uplink resource that is allocated in advance to the first user equipment according to the channel state indication information.

Specifically, the channel state indication information includes two types of indication information. The first type is indication information indicating that the channel state of the uplink channel corresponding to the first user equipment is an idle state, that is, the first user equipment has a channel for performing uplink data transmission, and when the base station receives the channel state indication information, The uplink resource allocated to the first user equipment may be scheduled to the first user equipment, so that the first user equipment uses the uplink resource to perform uplink data transmission.

The second type is a finger indicating that the channel state of the uplink channel corresponding to the first user equipment is not idle. The information indicating that the first user equipment does not have the channel for performing the uplink data transmission, the base station may re-allocate the uplink resource allocated to the first user equipment to the requesting uplink resource scheduling when receiving the channel state indication information. Second user device. That is, the base station allocates the uplink resource to other user equipments that request the uplink resource scheduling and the uplink channel state to be in an idle state when the first user equipment is unable to use the pre-allocated uplink resource for uplink data transmission, so that the Uplink resources can be fully utilized.

It should be noted that after the LAA system introduces the mechanism of listening and speaking, the uplink and downlink transmissions are respectively performed by the user equipment and the base station. The downlink transmission is performed by the base station after the first listening and then speaking process, that is, after the base station monitors, if the downlink channel is in an idle state, downlink data transmission may be performed on the scheduled downlink subframe. The uplink transmission is performed by the user equipment after the user listens, that is, after the user equipment monitors, if the uplink channel is in an idle state, uplink data transmission may be performed on the scheduled uplink subframe. However, the resources of the uplink and downlink data transmission are all scheduled by the base station, and after the first listening and speaking mechanism is introduced, in the downlink data transmission, the base station can learn the downlink resource scheduling result and the monitoring result of the channel state of the base station, and in the uplink data transmission, although the base station transmits Only the uplink resource scheduling result can be known but the monitoring result of the user equipment's channel state of use of the channel is not known. In this way, when the user equipment obtains the uplink channel in the non-idle state after the channel state is monitored, the base station does not know that the uplink channel of the user equipment is in the non-idle state, so that the uplink resource is still scheduled to the user equipment, so that the scheduled The uplink resource cannot be used by the user equipment, and cannot be used by other user equipments in which the uplink channel is in an idle state. Therefore, in the actual process, the uplink resources that have been scheduled are not effectively utilized, thereby causing waste of uplink resources.

In the embodiment of the present invention, the base station receives the channel state indication information reported by the first user equipment, and performs scheduling on the uplink resource allocated to the first user equipment according to the channel state indication information, and the base station may pass the first user. The channel state indication information reported by the device is used to learn the channel state of the uplink channel of the first user equipment, so that when the channel state of the uplink channel of the first user equipment is not idle, the uplink resource originally scheduled for the first user equipment It is allocated to other user equipments to avoid waste of uplink resources and improve utilization of uplink resources.

FIG. 3 is a flowchart of another uplink resource scheduling method according to an embodiment of the present disclosure, where the method includes:

Step S301: Receive uplink scheduling request information sent by the first user equipment and the third user equipment.

Specifically, the uplink scheduling request (SR) may be information that the user equipment requests the uplink resource scheduling from the base station when the uplink data transmission needs to be performed. In the scenario of the embodiment, the first user equipment and the third user equipment are user equipments that need to perform uplink data transmission, and therefore send uplink scheduling request information to the base station. It should be noted that the uplink resource herein may refer to at least one resource block in an uplink subframe or an uplink subframe. In addition, the number of the third user equipments in the embodiment of the present invention may include multiple.

Step S302: Allocating an uplink resource to the first user equipment and the at least one third user equipment, where the uplink resource allocated to the at least one third user equipment is the same as the uplink resource allocated to the first user equipment.

Specifically, after receiving the uplink scheduling request information sent by the first user equipment and the third user equipment, the base station may allocate uplink resources to the first user equipment and the third user equipment. In the embodiment of the present invention, the base station allocates the same uplink resource to the first user equipment and the third user equipment, so that the first user equipment and the third user equipment serve as candidate user equipments that use the same uplink resource that is scheduled.

In step S303, the uplink scheduling grant information is sent to the first user equipment and the third user equipment, where the uplink scheduling grant information is used to indicate that the first user equipment and the third user equipment are pre-assigned. The identifier of the same uplink resource.

Specifically, the base station may send, by using the uplink scheduling grant information (UL grant), the identifiers of the uplink resources allocated to the first user equipment and the third user equipment to the first user equipment and the third user equipment, respectively. In the embodiment of the present invention, the uplink scheduling grant information sent to the first user equipment and the third user equipment includes the foregoing in advance, because the base station allocates the same uplink resource to the first user equipment and the third user equipment that request the uplink resource scheduling. An identifier of the same uplink resource assigned to the first user equipment and the third user equipment.

Further, the uplink scheduling grant information may be further used to indicate that the first user equipment and the third user equipment are in the channel state indication information after listening to the channel status of the respective uplink channel.

Step S304: Acquire uplink transmission characteristic parameters of the first user equipment and the third user equipment, respectively.

Specifically, the uplink transmission characteristic parameter may refer to a related feature parameter such as channel quality, transmission data amount, and the like when the user equipment performs uplink transmission. In a specific implementation, the uplink transmission feature parameter may be pre-stored or obtained by the base station, or may be that the uplink scheduling request information sent by the first user equipment and the third user equipment carries the uplink transmission feature parameter in the step S301, so that the base station acquires Yes, here No specific limitation.

Step S305, determining, according to the uplink transmission characteristic parameter of the first user equipment and the third user equipment, that the user equipment with the scheduling priority being the first scheduling priority is the first user equipment, and the scheduling priority is The user equipment of the second scheduling priority is the third user equipment.

Specifically, the base station sorts the scheduling priorities of the first user equipment and the third user equipment according to the uplink transmission characteristic parameter and the preset scheduling algorithm, and the user equipment ranked in the first position is the first scheduling priority, and the ranking is in the first A subsequent user equipment can be considered as the second scheduling priority. In the implementation of the present invention, the base station may determine the user equipment of the first scheduling priority as the first user equipment, and determine the user equipment of the second scheduling priority as the third user equipment. That is, the user equipment that schedules the first priority is the first user equipment, and the other user equipments are the third user equipment.

Step S306: Send downlink control information to the first user equipment and the third user equipment, where the downlink control information includes first control information for indicating a scheduling priority corresponding to the user equipment.

Specifically, after determining the scheduling priority of the first user equipment and the third user equipment, the base station sends downlink control information (DCI, Downlink Control Information) to the first user equipment and the third user equipment, where the downlink control information is used. The first control information is used to indicate the scheduling priority corresponding to the user equipment, that is, the first control information in the downlink control information sent to the first user equipment indicates the first scheduling priority, and the third The first control information in the downlink control information sent by the user equipment indicates the second scheduling priority. For example, the first control information may be 1 bit of character information. When the first control information position is 1, the user equipment may be instructed to be the user equipment of the first scheduling priority; when the first control information position is 0, the indication may be indicated. The user equipment is a second scheduling priority user equipment.

The first control information is used to indicate that the first user equipment whose scheduling priority is the first scheduling priority directly uses the pre-allocated uplink resource to perform uplink data transmission when the channel state of the uplink channel is idle; indicating the scheduling priority The third user equipment of the second scheduling priority temporarily does not perform uplink data transmission. That is, when the first control information in the downlink control information received by the first user equipment is the first scheduling priority, the first user equipment may directly use step S303 when the channel state of the uplink channel is the idle state. The uplink resource corresponding to the identifier of the received uplink resource performs uplink data transmission. When the first control information of the downlink control information received by the third user equipment is the second scheduling priority, the third user equipment may not use the uplink resource corresponding to the identifier of the uplink resource received in step S303 for uplink data. transmission.

It should be noted that the first control information may be one type of information added in the downlink control information or one type of information carried by redundant bits in the downlink control information. The so-called redundant bits may be values that are not defined in the original system (such as reserved values); or are not used in some specific scenarios, but are occupied by the system in other specific scenarios.

Step S307: Receive channel state indication information reported by the first user equipment.

Specifically, the first user equipment can monitor the channel state of the uplink channel in real time, and when receiving the uplink scheduling grant information or the downlink control information, report the channel state indication information to the base station; the first user equipment may also receive the uplink scheduling grant information. After the downlink control information is sent, the channel state of the uplink channel is triggered, and the channel state indication information is reported to the base station, which is not specifically limited.

Step S308, when the channel state of the uplink channel of the first user equipment indicated by the channel state indication information is a non-idle state, searching for at least one third user equipment that allocates the same uplink resource as the first user equipment.

Specifically, if the channel state indication information reported by the first user equipment received by the base station in step S307 indicates that the channel state of the uplink channel of the first user equipment is not idle, the base station searches for the same uplink resource as the first user equipment. At least one third user device. The at least one third user equipment means that the third user equipment may be one or multiple.

Step S309: Obtain channel state indication information reported by the third user equipment.

Specifically, the channel state indication information of the third user equipment may be reported by the third user equipment to the base station when receiving the uplink scheduling grant information or the downlink control information, where the base station determines that the channel status of the uplink channel of the first user equipment is non- In the idle state, the channel state indication information reported by the third user equipment is further obtained.

Step S310: Determine, according to the channel state indication information reported by the third user equipment, a third user equipment whose channel state of the uplink channel in the at least one third user equipment is in an idle state, as the second user equipment.

Specifically, the base station may determine, according to the channel state indication information reported by the third user equipment, a third user equipment that is in an idle state in the at least one third user equipment, and uses the third user equipment as the second User equipment.

Step S311: Send supplementary scheduling information to the second user equipment, where the supplementary scheduling information is used to instruct the second user equipment to perform uplink data transmission by using the uplink resource that is allocated in advance.

Specifically, the supplementary scheduling information may be used to indicate that the user equipment uses the pre-allocated uplink resource to perform Line data transfer. In the embodiment of the present invention, the base station sends the supplementary scheduling information to the second user equipment, and after receiving the supplementary scheduling information, the second user equipment may use the uplink resource corresponding to the identifier of the uplink resource received in step S303 to perform uplink. data transmission. Optionally, the supplementary scheduling information may be carried by the downlink control information. Further, the supplementary scheduling information may further carry information such as a time point at which the second user equipment is required to perform uplink data transmission, so that the second user equipment performs uplink data transmission according to the information.

In the embodiment of the present invention, the base station, in advance, the user equipment (ie, the first user equipment and the third user equipment) that requests the uplink scheduling is used as the candidate user equipment, allocates the same uplink resource, and sends the uplink scheduling grant information to the candidate user. The device determines the scheduling priority of the candidate user equipment and sends the downlink user control information to the candidate user equipment, so that the first user equipment in the candidate user equipment with the scheduling priority of the first scheduling priority may be in the uplink channel state. When idle, the uplink data transmission is directly used by using the pre-allocated uplink resources, which saves the signaling overhead of the base station. On the other hand, when the uplink channel state of the first user equipment with the priority of the first scheduling priority is scheduled to be non-idle in the candidate user equipment, the base station may make the priority the second scheduling priority by supplementing the scheduling information. A third user equipment in the three-user equipment with the channel state of the uplink channel in the idle state uses the pre-allocated uplink resources to perform uplink data transmission, thereby avoiding waste of uplink resources and improving utilization of uplink resources.
