In this way, the LTE base station can utilize the unlicensed spectrum cell and the UE for data communication. However, due to possible competition and collisions on unlicensed spectrum cells, unlicensed spectrum cells are sometimes available and sometimes unavailable.

FIG. 1 is a schematic structural diagram of Embodiment 1 of a user equipment according to the present invention. As shown in FIG. 1, the user equipment includes: a transceiver 10 and a processor 11. The transceiver 10 is configured to receive a notification message sent by the base station, where the notification message is used to notify the UE that the unlicensed spectrum cell is available, and the processor 11 is configured to determine the unlicensed spectrum according to the foregoing notification message and the pre-agreed reference cell. a reference timing that is available to the cell; wherein the reference cell is a time reference for the processor 11 to determine that the unlicensed spectrum cell is available, and the reference cell is an authorized spectrum cell; and determining, according to the reference timing, a system frame number on the unlicensed spectrum cell ( a system frame number (hereinafter referred to as SFN) and a subframe number; and determining, according to the SFN, the subframe number, and a preset periodic resource parameter, a location of a periodic resource on the unlicensed spectrum cell; the transceiver 10, And transmitting, by the base station, a periodic resource, where the periodic resource is located, where the location of the periodic resource is a specific resource transmission time.

Specifically, the transceiver 10 receives the notification message sent by the base station, which may be from the perspective of the licensed spectrum cell, that is, the UE determines the time when the notification message is received by using the authorized spectrum cell as a reference, The transceiver 10 receives the notification message at the time of the TO, and the TO time actually corresponds to the start time corresponding to a certain subframe on a certain radio frame on the licensed spectrum cell. The foregoing notification message may be a Radio Resource Control (RRC) message, or may be a Media Access Control (MAC) layer message, or may be a physical layer (Physical, hereinafter referred to as PHY).

The form of the notification message is not limited in the embodiment of the present invention.

It should be noted that, when the time when the transceiver 10 receives the notification message corresponds to a different cell, the corresponding radio frame and the subframe are different. Therefore, the transceiver 10 passes the processor 11 before receiving the notification message. It is agreed in advance with the base station which cell is the time reference, that is, the reference cell is previously agreed with the base station. And the base station and the UE agree to the reference cell in advance, and the corresponding configuration message is transmitted between the base station and the UE, and the reference cell is mutually agreed by the configuration message; or the reference cell is specified in the protocol, and the base station and the UE are all specified according to the protocol. The reference cell determines the reference timing.

Taking FIG. 2 as an example, it is assumed that the transceiver 10 receives the notification message sent by the base station on the SFN=0 of the reference cell and the subframe number=2 (ie, the third subframe of the first radio frame), and the processor 11 The start time corresponding to the third subframe (assumed to be the above T0 time) is determined as the reference timing available to the unlicensed spectrum cell.

After the processor 11 determines the T0 time as the reference timing, the T0 time is corresponding to the unlicensed spectrum cell, that is, the SFN and the subframe number on the unlicensed spectrum cell corresponding to the reference timing are determined, as shown in FIG. 2, SFN=0 on the unlicensed spectrum cell corresponding to the reference timing, and the subframe number=0 (ie, the first subframe of the first radio frame).

The base station sends the configured periodic resource parameter to the UE in advance, and the periodic resource parameter is used to determine the location of the periodic resource transmitted between the base station and the UE. Optionally, the periodic resource may be a downlink reference signal CRS, and/or an uplink reference signal SRS, and/or an uplink SR, and/or an uplink CQI reporting resource, where the periodic resource parameter includes a periodic resource. The period of occurrence (that is, how many ms each appears), the offset (along with the period, used to determine which subframe the periodic resource appears on), the location of the frequency resource, and so on. The processor 11 determines, according to the SFN, the subframe number, and the periodic resource parameter on the unlicensed spectrum cell, the location of the periodic resource on the unlicensed spectrum cell, where the location is specifically a specific moment of periodic resource transmission; The UE transmits the corresponding period on the periodic resource location by the transceiver 10 and the base station. The resources, so that the UE and the base station only perform data transmission, decoding, and the like at the time of periodic resource transmission. The unlicensed spectrum cell is available at the time of the periodic resource transmission determined by the embodiment of the present invention, so that the problem that the UE and the base station still use the periodic resource for decoding and transmitting data when the unlicensed spectrum cell is unavailable is avoided. Improve the quality of communication.

In addition, the reference timing determined by the processor 11 may also be used for scheduling timing, Hybrid Automatic Repeat Request (HARQ) timing, random access procedure timing, and discontinuous reception (Di scontinuous Reception, below). The calculation of the semi-peristent Scheduling (hereinafter referred to as SPS) resource, etc., is not described herein.

Specifically, if the notification message does not include the start time available to the unlicensed spectrum cell, the notification message sent by the base station to the UE is actually notifying the UE that the current unlicensed spectrum cell is currently available, and the processor 11 may receive the notification. The time of the message is determined as the reference timing; if the notification message includes the start time available to the unlicensed spectrum cell, the base station sends a notification message to the UE, which may be to inform the UE that the time when the notification message is received by the processor 11 is determined as the reference timing. And further informing when the unlicensed spectrum cell starts to be available; or notifying the UE of the start time available to the unlicensed spectrum cell by the processor 11 as the reference timing, the reference timing and the available starting time of the unlicensed spectrum cell actually The above is the same.

Specifically, the reference cell in this embodiment may be previously agreed by the base station and the UE, or may be specified by the protocol, that is, the cell where the UE receives the notification message is used as the reference cell, and the cell may be the primary cell, or may be Other auxiliary cells. If the transceiver 10 receives the notification message sent by the base station at the first time of the reference cell, the first time may be a start time corresponding to a certain subframe of the reference cell, and may also be a certain radio frame of the reference cell. The starting time corresponding to a certain subframe. Here are two simple examples. The reference cells in both examples are primary cells, that is, the transceiver 10 receives the notification message in the primary cell:

Example 1: When the transceiver 10 receives the notification message that informs the UE that the unlicensed spectrum cell is available when the subframe number of the primary cell is 2 (see the example of FIG. 2), the processor 11 determines the primary cell subframe number = The start time corresponding to the subframe of 2 is the start of the timing available for the unlicensed spectrum cell, that is, as the reference timing available to the unlicensed spectrum cell, the processor 11 corresponds the reference timing to the unlicensed spectrum cell, The SFN and the subframe number corresponding to the reference timing are determined on the authorized spectrum cell (the corresponding SFN=0 in FIG. 2, the subframe number=0), that is, the available start time of the unlicensed spectrum cell is its own SFN=0, Subframe with frame number = 0. Finally, the processor 11 determines the location of the periodic resource according to the SFN, the subframe number, and the preset periodic resource parameter, and transmits the periodic resource to the base station at the location of the periodic resource, for example, may be periodic. The receiving measurement CRS may also be a periodic channel state information reference signal (CSI-RS), or may be sent on a periodic CQI resource and sent on a periodic SRS resource. The SRS uses a periodic SR resource to send an SR or the like. Optionally, the base station may further notify the UE of the duplex mode of the unlicensed spectrum cell, such as Frequency Division Duplexing (French Division Duplexing), Time Division Duplexing (hereinafter referred to as TDD). In the case of FDD, FDD DL Only or FDD UL Only may also be notified. In the case of TDD, the uplink and downlink ratio of TDD may also be included, so that the processor 11 can better determine. The location of the periodic resource.

Example 2: When the transceiver 10 receives the notification message that the unlicensed spectrum cell is available when the primary cell SFN=0 and the subframe number=1, the UE determines that the primary cell SFN=0, the subframe number=1 corresponds to The start time is used as the start of the timing of the unlicensed spectrum, that is, as the reference timing available to the unlicensed spectrum cell, the processor 11 associates the reference timing to the unlicensed spectrum cell, and determines the reference on the unlicensed spectrum cell. The SFN and subframe number corresponding to the timing (where the SFN continues to use SFN=0 in the reference cell). That is, if the processor 11 determines the SFN number on the reference cell when receiving the notification message, the processor 11 can directly use the SFN number on the reference cell when determining the SFN number on the corresponding unlicensed spectrum cell.

The user equipment provided by the embodiment of the present invention receives, by using a transceiver, a notification message sent by the base station to notify the UE that the unlicensed spectrum cell is available, at the first moment of the reference cell, and the processor determines that the first time is available as an unlicensed spectrum cell. Referring to the timing, and determining the SFN and the subframe number on the unlicensed spectrum cell according to the reference timing, and finally determining the periodic resources on the unlicensed spectrum cell according to the determined SFN, the subframe number, and the preset periodic resource parameter. Position, and transmit periodic resources to the base station at the location through the transceiver. The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The quality of user communication.

On the basis of the foregoing embodiment, as a second feasible implementation manner of the embodiment of the present invention, the embodiment relates to that the transceiver 10 receives the notification message sent by the base station at the second moment in the non-reference cell, and the processor 11 Determine the specific process of reference timing. Further, the transceiver 10 is specifically configured to receive the notification message sent by the base station at a second moment in the non-reference cell; the processor 11 is specifically configured to use the second moment and the reference Corresponding to the first moment in the cell; and using the first moment as a reference timing available to the unlicensed spectrum cell.

Specifically, the reference cell in this embodiment may be previously agreed by the base station and the UE, or may be specified by the protocol, that is, the cell that receives the notification message by the UE may also be a non-reference cell. For example, the UE receives the notification message sent by the base station in the cell one (non-reference cell), but the reference cell agreed by the base station and the UE is the primary cell. It should be noted that the non-reference cell here is also a licensed spectrum cell.

If the transceiver 10 receives the notification message sent by the base station at the second time of the non-reference cell, the second time may be a start time corresponding to a certain subframe of the non-reference cell, and may also be the non-parameter The start time corresponding to a certain subframe on a certain radio frame of the cell. At this time, the processor 11 will correspond to the second time when the notification message is received to the reference cell (the same time corresponds to a different cell, and the corresponding subframe or radio frame is different), the second time and the reference Corresponding to the first moment in the cell, the processor 11 determines the first moment of the reference cell as the reference timing of the unlicensed spectrum cell. Afterwards, the processor 11 corresponds the reference timing to the unlicensed spectrum cell, and determines the SFN and the subframe number corresponding to the reference timing on the unlicensed spectrum cell, and according to the SFN, the subframe number, and the preset periodic resource. The parameter determines the location of the periodic resource, and transmits the periodic resource to the base station at the location of the periodic resource, for example, may be a periodic receiving measurement CRS, or may be a periodic receiving CSI-RS, or may be The CQI is sent on the periodic CQI resource, the SRS is sent on the periodic SRS resource, and the SR is sent by using the periodic SR resource. Optionally, the base station may further notify the UE of the duplex mode of the unlicensed spectrum cell, such as FDD and TDD. In the case of FDD, the FDD DL Only or FDD UL Only may also be notified, where the TDD may also include the TDD. The uplink and downlink ratios are used to enable the processor 11 to better determine the location of the periodic resources.

In addition, whether it is the first feasible implementation manner of the embodiment of the present invention or the second feasible implementation manner, the content of the notification message received by the transceiver 10 may still be an unlicensed spectrum cell available, an unlicensed spectrum cell. At least one of an available start time, an end time available for the unlicensed spectrum cell, and a time length available for the unlicensed spectrum cell, except that the base station and the UE agree to receive the reception time of the notification message to the reference. In the cell, the time corresponding to the reference cell is used as the reference timing available for the unlicensed spectrum cell.

The user equipment provided by the embodiment of the present invention receives, by the transceiver, a notification message sent by the base station to notify the UE that the unlicensed spectrum cell is available, and the processor corresponds the second time to the reference cell. Determining, by the first moment, a reference timing that is available to the unlicensed spectrum cell, and determining, according to the reference timing, the SFN and the subframe number on the unlicensed spectrum cell, and finally determining the SFN, the subframe number, and the pre-determination according to the determined The periodic resource parameter is determined to not authorize the location of the periodic resource on the spectrum cell, and the periodic resource is transmitted to the base station by the transceiver at the location. The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The quality of user communication.

On the basis of the foregoing embodiment, as a third feasible implementation manner of the embodiment of the present invention, this embodiment relates to the start time of the processor 11 to use the unlicensed spectrum cell in the notification message. The specific process of engraving the reference timing available as an unlicensed spectrum cell. Further, the above processor

And determining, according to the reference cell, a start time that is available to the unlicensed spectrum cell in the notification message as a reference timing that is available to the unlicensed spectrum cell.

Specifically, in the content of the notification message received by the transceiver 10 in this embodiment, the start time of the unlicensed spectrum cell needs to be included, optionally, except that the start time of the unlicensed spectrum cell is available. And may further include at least one of an unlicensed spectrum cell available, an end time available for the unlicensed spectrum cell, and a time length available for the unlicensed spectrum cell, except that the base station and the UE agree to use the unlicensed spectrum cell in the notification message. The start time is used as the reference timing available for the unlicensed spectrum cell. Therefore, before the base station, the base station specifies, according to the reference cell that is previously agreed with the UE, that the start time corresponding to a certain subframe in the reference cell is a start time available for the unlicensed spectrum cell, and the unlicensed spectrum cell is used. The available start time is carried in the notification message and sent to the UE. It should be noted that the transceiver 10 receiving the notification message at this time may be received in the non-reference cell, or may be received in the reference cell, as long as the finally determined reference timing is available in the unlicensed spectrum cell in the notification message. The starting time is correct.

a notification message that is available to the unlicensed spectrum cell of the UE, the processor determines a start time available for the unlicensed spectrum cell in the notification message as a reference timing available to the unlicensed spectrum cell, and determines, according to the reference timing, the unlicensed spectrum cell SFN and the subframe number, and finally determining the location of the periodic resource on the unlicensed spectrum cell according to the determined SFN, the subframe number, and the preset periodic resource parameter, and transmitting the periodic resource to the base station by using the transceiver at the location . The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The quality of user communication.

On the basis of the foregoing embodiments, the fourth feasible embodiment of the present invention is an implementation manner. The embodiment relates to a specific process for determining, by the processor 11, the SFN and the subframe number on the unlicensed spectrum cell according to the reference timing. . Further, the transceiver 10 is further configured to: before receiving the notification message sent by the base station, receive a timing reference indication sent by the base station; where the processor 11 is specifically configured to determine, according to the timing reference indication, on the unlicensed spectrum cell. The SFN and subframe number corresponding to the reference timing.

Specifically, the transceiver 10 notifies the processor when receiving the timing reference indication sent by the base station. 11. The processor 11 determines, according to the timing reference indication and the previously determined reference timing, the SFN and the subframe number corresponding to the reference timing on the unlicensed spectrum cell. The timing reference indication is used to indicate to the UE which SFN and subframe number the processor 11 should convert the determined reference timing to, because the processor 11 determines the non-authorization based on the same reference timing, depending on the timing reference indication. The SFN and subframe number on the spectrum cell can be different. The example shown in FIG. 2 above is a way for the processor 11 to determine the SFN and the subframe number of the unlicensed spectrum cell according to the reference timing (the determined SFN=0, the subframe number=0), and there may be other The method is to determine the SFN and the subframe number of the unlicensed spectrum cell, that is, FIG. 2 and FIG. 3 determine different SFN and subframe numbers with the same reference timing.

Referring to FIG. 3, the reference cell is a primary cell. When the transceiver 10 receives a notification message indicating that the unlicensed spectrum cell is available when the primary cell subframe number=2, the processor 11 determines that the primary cell subframe number=0 corresponds. The start time is the start of the timing available for the unlicensed spectrum cell, that is, the reference timing available as the unlicensed spectrum cell; the processor 11 corresponds the reference timing to the SFN=0 on the unlicensed spectrum cell, and the subframe number=2 The unlicensed spectrum cell corresponding to the subframe with the subframe number=0 and the subframe number=1 cannot be used, and the subframe from the subframe number=1 is used, the unlicensed spectrum cell can be used; that is, the processor 1 1 Determining the start time corresponding to SFN=0 and subframe number=2 on the reference cell as the reference timing available to the unlicensed spectrum cell, and using SFN=0 and subframe number=2 on the unlicensed spectrum cell, BP The timing of the unlicensed spectrum cell is completely synchronized with the timing of the reference cell, including the SFN and the subframe number, and the unlicensed spectrum cell can be used only when the spectrum resource of the unlicensed spectrum cell is notified.

It should be noted that the processor 11 determines the SFN and the subframe number according to the same reference timing, that is, the timing reference indication is specifically configured, and may be configured by the base station for the UE, or the base station and the UE agree.

Further, after the processor 11 determines the SFN and the subframe number of the unlicensed spectrum cell (regardless of which SFN and subframe number is determined), the processor 11 may further determine the SFN, the subframe number, and the preset. The DRX parameter determines the activation or shutdown timing of the DRX of the UE on the unlicensed spectrum cell to save the power consumption of the UE. Optionally, the DRX parameter may be a DRX cycle, such as: a long DRX cycle, a short DRX cycle, a routine duration (On duration) timer, a routine activation time start offset, or a non-active The timer may be a parameter such as a retransmission timer. The DRX parameter is not limited in the embodiment of the present invention, as long as it can be combined with the SFN and the subframe number of the unlicensed spectrum cell determined by the processor 11 to determine the DRX of the UE. Activate or turn off the moment. The user equipment provided by the embodiment of the present invention receives, by the transceiver, a notification sent by the base station for notification.

a notification message that is available to the unlicensed spectrum cell of the UE, the processor determines a start time available for the unlicensed spectrum cell in the notification message as a reference timing that is available to the unlicensed spectrum cell, and combines the timing of the base station configuration with the UE according to the reference timing. Determining, by using the indication, the SFN and the subframe number on the unlicensed spectrum cell, and finally determining the location of the periodic resource on the unlicensed spectrum cell according to the determined SFN, the subframe number, and the preset periodic resource parameter, and passing the transceiver Periodic resources are transmitted with the base station at this location. The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The user communication quality is determined; and the DRX activation or shutdown time of the UE is determined by the determined SFN and subframe number on the unlicensed spectrum cell and the preset DRX parameter, thereby saving power consumption of the UE.

FIG. 4 is a schematic structural diagram of Embodiment 1 of a base station according to the present invention. As shown in FIG. 4, the base station includes: a processor 20 and a transmitter 21. The transmitter 21 is configured to send a periodic resource parameter to the UE, where the processor 20 is configured to allocate a reference cell with the UE, where the reference cell determines, for the UE, the available time of the unlicensed spectrum cell. The reference cell is a licensed spectrum cell, and the transmitter 21 is further configured to send a notification message to the UE, where the notification message is used to notify the UE that the unlicensed spectrum cell is available, so that the UE is used. Determining a reference timing of the unlicensed spectrum cell according to the notification message and the reference cell, and determining a location of the periodic resource according to the reference timing and the periodic resource parameter, where the periodic resource A periodic resource is transmitted with the base station at a location.

Specifically, the transmitter 21 sends a periodic resource parameter to the UE, where the periodic resource parameter is used to determine the location of the periodic resource transmitted between the base station and the UE. Optionally, the periodic resource may be a downlink reference signal CRS, and/or an uplink reference signal SRS, etc., where the periodic resource parameter includes a period in which periodic resources occur (ie, how many ms each subframe appears on) ), offset, frequency resource location, etc. In addition, the processor 20 pre-associates a reference cell with the UE, and the reference cell determines, for the UE, a time reference available to the unlicensed spectrum cell, where the reference cell is an authorized spectrum cell. Moreover, the processor 20 and the UE agree in advance that the reference cell may be a base station and The corresponding configuration message is transmitted between the UEs, and the reference cell is mutually agreed by the configuration message, and the reference cell may be specified in the protocol.

The transmitter 21 sends a notification message to the UE, which is used to notify the UE that the unlicensed spectrum is small. The UE is configured to receive the notification message, and the UE may receive the notification message from the perspective of the authorized spectrum cell, that is, the UE uses the authorized spectrum cell as a reference (ie, one of the authorized spectrum cells as the reference cell) to determine that the notification message is received. Moment. It is assumed that the UE receives the notification message at the time of the TO, and the TO time actually corresponds to the start time corresponding to a certain subframe on a certain radio frame on the reference cell. The foregoing notification message may be an RRC message, may also be a MAC layer message, may also be a PHY message, may also be a dedicated message for notifying a specific UE, or may be a multicast message or a broadcast message for notifying a group of UEs or all UEs. The embodiment of the present invention does not limit the form of the notification message.

It should be noted that, if the time when the UE receives the notification message corresponds to a different cell, the corresponding radio frame and the subframe are different. Therefore, the processor 20 and the UE pre-agreed the purpose of the reference cell in order to enable The UE corresponds to the time when the notification message is received to a fixed reference cell.

Taking FIG. 2 as an example, it is assumed that the UE receives the notification message sent by the transmitter 21 on the SFN=0 of the reference cell and the subframe number=2 (ie, the third subframe of the first radio frame), the UE will The start time corresponding to the third subframe (assumed to be the TO time) is determined as the reference timing available to the unlicensed spectrum cell, and the TO time is corresponding to the unlicensed spectrum cell, that is, the unlicensed spectrum corresponding to the reference timing is determined. The SFN and the subframe number on the cell, as shown in FIG. 2, the SFN=0 on the unlicensed spectrum cell corresponding to the reference timing, and the subframe number=0 (ie, the first subframe of the first radio frame).

Determining, by the UE, the location of the periodic resource on the unlicensed spectrum cell according to the SFN, the subframe number, and the periodic resource parameter on the unlicensed spectrum cell, where the location is specifically a specific moment of periodic resource transmission; The base station transmits corresponding periodic resources on the periodic resource location, so that the UE and the base station perform data transmission, decoding, and the like only at the time of periodic resource transmission. The unlicensed spectrum cell is available at the time of the periodic resource transmission determined by the embodiment of the present invention, so that the problem that the UE and the base station still use the periodic resource for decoding and transmitting data when the unlicensed spectrum cell is unavailable is avoided. Improve the quality of communication.

In addition, the reference timing determined by the UE may be used for the calculation of the scheduling timing, the HARQ timing, the random access procedure timing, the DRX timing, the SPS resource, and the like, which are not described herein again.

The base station provided by the embodiment of the present invention allocates a reference cell to the UE by using the processor, and sends a notification message and a periodic resource parameter for notifying the unlicensed spectrum cell of the UE to the UE by using the transmitter. And determining, by the UE, the reference timing of the unlicensed spectrum cell according to the notification message and the reference cell, and determining the location of the periodic resource according to the reference timing and the periodic resource parameter, where the periodic resource is transmitted with the UE. The base station provided by the embodiment of the present invention enables the UE to improve the accuracy of the data when the unlicensed spectrum cell is available, and the data is decoded and transmitted according to the periodic resource at the time of the determined periodic resource transmission. Improve the quality of user communication.

Specifically, if the notification message sent by the transmitter 21 to the UE does not include the start time available to the unlicensed spectrum cell, the notification message sent by the transmitter 21 to the UE actually informs the UE that the current unlicensed spectrum cell is currently available. The UE may determine the time when the notification message is received as the reference timing. If the notification message includes the start time available to the unlicensed spectrum cell, the sender 21 sends a notification message to the UE, which may be to inform the UE that the notification message will be received. The time is determined as the reference timing, and further informs the unlicensed spectrum cell when it is available. It may also be that the UE is informed of the available start time of the unlicensed spectrum cell as the reference timing, and the reference timing and the available start time of the unlicensed spectrum cell are available. It's actually the same. As for the case where the notification message includes the start time available to the unlicensed spectrum cell, whether the UE uses the time when the notification message is received as the reference timing or the available time of the unlicensed spectrum cell as the reference timing can be passed through the processor. 20 is implemented with the UE's convention of reference timing. Specifically, there are three implementation methods:

The first implementation manner is as follows: The cell that receives the notification message by the UE is the reference cell.

The reference cell here may be previously agreed by the processor 20 and the UE, or may be specified by the protocol, that is, the cell where the UE receives the notification message is used as the reference cell, and the cell may be the primary cell or other auxiliary cells. . If the UE receives the notification message sent by the base station at the first time of the reference cell, the first time may be a start time corresponding to a certain subframe of the reference cell, and may also be a certain radio frame of the reference cell. The starting time corresponding to one subframe. Here are two simple examples. The reference cells in both examples are the primary cells, that is, the UE receives the notification message in the primary cell:

Example 1: When the UE receives the transmitter in the subframe number of the primary cell = 2 (see the example in Figure 2)

The notification message that is sent by the UE to the unlicensed spectrum cell is notified, and the start time corresponding to the subframe of the subframe number=2 of the primary cell is determined as the start of the available timing of the unlicensed spectrum cell. That is, as the reference timing available to the unlicensed spectrum cell, and the reference timing is mapped to the unlicensed spectrum cell, and the SFN and the subframe number corresponding to the reference timing are determined on the unlicensed spectrum cell (the corresponding SFN=0 in FIG. 2) , subframe number = 0), that is, the start time available for the unlicensed spectrum cell is a subframe whose own SFN=0 and subframe number=0. Finally, the UE determines the location of the periodic resource according to the SFN, the subframe number, and the preset periodic resource parameter, and transmits the periodic resource to the base station at the location of the periodic resource, for example, may be a periodic receiving measurement. The CRS may also be a periodic CSI-RS, or may send a CQI on a periodic CQI resource, send an SRS on a periodic SRS resource, and send an SR using a periodic SR resource. Optionally, the base station may further notify the UE of the duplex mode of the unlicensed spectrum cell, such as FDD and TDD. In the case of FDD, the FDD DL Only or the FDD UL Only may also be notified; wherein the TDD may also include the TDD. The uplink and downlink ratios are used to enable the UE to better determine the location of the periodic resources.

Example 2: When the UE receives the notification message sent by the transmitter 21 to notify the unlicensed spectrum cell that the primary cell is SFN=0 and the subframe number=1, the UE determines that the primary cell SFN=0, the subframe number= Corresponding start time is used as the start of the timing of the unlicensed spectrum, that is, as a reference timing available to the unlicensed spectrum cell, and the reference timing is corresponding to the unlicensed spectrum cell, and is determined on the unlicensed spectrum cell. The SFN and subframe number corresponding to the reference timing (where the SFN continues to use SFN=0 in the reference cell). That is, if the UE determines the SFN number on the reference cell when receiving the notification message, the SFN number on the reference cell can be directly used when determining the SFN number on the corresponding unlicensed spectrum cell.

The second implementation manner is as follows: The cell that receives the notification message by the UE is a non-reference cell.

The reference cell may be previously agreed by the base station and the UE, or may be specified by the protocol, but the cell that receives the notification message by the UE may also be a non-reference cell. For example, the UE receives the notification message sent by the base station in the cell one (non-reference cell), but the reference cell agreed by the base station and the UE is the primary cell. It should be noted that the non-reference cell here is also a licensed spectrum cell.

If the UE receives the notification message sent by the transmitter 21 at the second time of the non-reference cell, the second time may be a start time corresponding to a certain subframe of the non-reference cell, and may also be a certain non-reference cell. The starting moment corresponding to a certain subframe on a radio frame. The UE then corresponds to the second time when the notification message is received to the reference cell (the same time corresponds to a different cell, and the corresponding subframe or radio frame is different), and the second time is in the reference cell. The first moment corresponds to, and determines the first moment of the reference cell as the reference timing of the unlicensed spectrum cell. After that, the UE will The reference timing corresponds to the unlicensed spectrum cell, and the SFN and the subframe number corresponding to the reference timing are determined on the unlicensed spectrum cell, and the periodic resource is determined according to the SFN, the subframe number, and the preset periodic resource parameter. Location, and transmitting periodic resources with the base station at the location of the periodic resource.

In addition, whether in the foregoing first implementation manner or the second manner, the content in the notification message received by the UE may still be an unlicensed spectrum cell available, an initial time available for the unlicensed spectrum cell, and an unlicensed spectrum cell available. At least one of the ending time and the length of time available for the unlicensed spectrum cell, except that the processor 20 and the UE agree that the receiving moment of receiving the notification message may be corresponding to the reference cell, and corresponding to the reference cell. The time is used as the reference timing available to the unlicensed spectrum cell.

The third implementation manner is as follows: The cell in which the UE receives the notification message may be a reference cell or a non-reference cell. However, the received notification message needs to include the available start time of the unlicensed spectrum cell.

Optionally, the notification message may include, in addition to the start time available for the unlicensed spectrum cell, an unlicensed spectrum cell available, an end time available for the unlicensed spectrum cell, and at least one of the available lengths of the unlicensed spectrum cell. For example, only the start time that the processor 20 and the UE agree to use the unlicensed spectrum cell in the notification message is used as the reference timing available for the unlicensed spectrum cell. Therefore, before the processor 20 specifies the starting time corresponding to a certain subframe in the reference cell as the starting time available for the unlicensed spectrum cell according to the reference cell that is previously agreed with the UE, and the non-authorized The available start time of the spectrum cell is carried in the notification message and sent to the UE by the transmitter 21.

The base station provided by the embodiment of the present invention sends a notification message and a periodic resource parameter for notifying the unlicensed spectrum cell of the UE to the UE through the processor and the agreed reference cell, so that the UE according to the notification message and the reference cell Determining a reference timing available to the unlicensed spectrum cell, and determining a location of the periodic resource according to the reference timing and the periodic resource parameter, where the periodic resource is transmitted with the UE. The base station provided by the embodiment of the present invention enables the UE to improve the accuracy of the data when the unlicensed spectrum cell is available, and the data is decoded and transmitted according to the periodic resource at the time of the determined periodic resource transmission. Improve the quality of user communication.

On the basis of the foregoing embodiment, further, the embodiment is that the transmitter 21 sends a timing reference indication to the UE before sending the notification message to the UE, so that the UE determines, according to the timing reference indication, that the unlicensed spectrum cell is available. The specific process of SFN and subframe number. Specifically, after receiving the timing reference indication sent by the transmitter 21, the UE determines the SFN and the subframe number corresponding to the reference timing on the unlicensed spectrum cell according to the timing reference indication and the reference timing determined by the previous UE. The timing reference indication is used to indicate to the UE how the SFN and the subframe number should be converted into the determined reference timing, because the SFN and the child on the unlicensed spectrum cell determined by the UE according to the same reference timing are different according to the timing reference indication. The frame number can be different. The example shown in FIG. 2 above is one way for the UE to determine the SFN and the subframe number of the unlicensed spectrum cell according to the reference timing (the determined SFN=0, the subframe number=0), and there may be other manners. The SFN and the subframe number of the unlicensed spectrum cell are determined, that is, FIG. 2 and FIG. 3 determine different SFN and subframe numbers with the same reference timing.

Referring to FIG. 3, the reference cell is a primary cell, and when the UE receives the transmitter in the primary cell subframe number=2,

After the notification message sent by the unlicensed spectrum cell is notified, the UE determines the start time corresponding to the primary cell subframe number=0 as the start of the available timing of the unlicensed spectrum cell, that is, as the unlicensed spectrum cell is available. Referring to the timing, the reference timing is corresponding to the SFN=0 on the unlicensed spectrum cell, the subframe number is 2, and the unlicensed spectrum cell corresponding to the subframe with the subframe number=0 and the subframe number=1 cannot be used. For a sub-frame number = 1 or later, the unlicensed spectrum cell can be used; that is, the UE determines the start time corresponding to SFN=0 and subframe number=2 on the reference cell as a reference for the unlicensed spectrum cell. Timing, and SFN=0, subframe number=2 is applied to the unlicensed spectrum cell, that is, the timing of the unlicensed spectrum cell is completely synchronized with the timing of the reference cell, including the SFN and the subframe number, only to notify the unlicensed spectrum cell. Unlicensed spectrum cells can be used when spectrum resources are available.

It should be noted that the UE determines the SFN and the subframe number according to the same reference timing, that is, the timing reference indication is specifically configured, and may be configured by the processor 20 for the UE, or the base station and the UE agree.

Further, before the transmitter 21 sends the notification message to the UE, the processor 20 may further send the DRX parameter to the UE, so that the UE determines the SFN and the subframe number of the unlicensed spectrum cell (whether it is determined which SFN and the child are determined). The frame number is determined according to the SFN, the subframe number, and the preset DRX parameter, and the activation or shutdown timing of the DRX of the UE is determined on the unlicensed spectrum cell to save the power consumption of the UE. Optionally, the DRX parameter may be a DRX cycle, such as: a long DRX cycle, a short DRX cycle, a routine activation time (On durat ion) timer, a routine activation time start offset, or a non- The activation timer is also a parameter such as a retransmission timer. The DRX parameter is not limited in the embodiment of the present invention, as long as the SFN and the sub-defined spectrum cell are determined by the UE. The frame numbers are combined to determine the DRX activation or shutdown timing of the UE.

The base station provided by the embodiment of the present invention allocates a reference cell to the UE by using the processor, and sends a notification message and a periodic resource parameter for notifying the unlicensed spectrum cell of the UE to the UE by using the transmitter, so that the UE according to the notification message and the reference The cell determines a reference timing that is available to the unlicensed spectrum cell, and determines an SFN and a subframe number on the unlicensed spectrum cell according to the reference timing and a timing reference indication sent by the transmitter to the UE, and finally according to the determined SFN, the subframe number, and And the periodic resource parameter determines the location of the periodic resource, where the periodic resource is transmitted with the UE. The base station provided by the embodiment of the present invention enables the UE to improve the accuracy of the data when the unlicensed spectrum cell is available, and the data is decoded and transmitted according to the periodic resource at the time of the determined periodic resource transmission. The user communication quality is improved; and the DRX parameter is sent to the UE by the transmitter, so that the UE determines the DRX activation or shutdown time of the UE according to the determined SFN and the subframe number and the DRX parameter on the unlicensed spectrum cell, thereby saving the UE's consumption. Electricity. FIG. 5 is a schematic structural diagram of Embodiment 2 of a user equipment according to the present invention. As shown in FIG. 5, the user equipment includes: a transceiver module 30, a first determining module 31, and a second determining module 32. The transceiver module 30 is configured to receive a notification message sent by the base station, where the notification message is used to notify the UE that the unlicensed spectrum cell is available. The first determining module 31 is configured to determine the non-predetermined reference cell according to the foregoing notification message. a reference timing that is available to the licensed spectrum cell; wherein the reference cell is a time reference for the UE to determine the available spectrum of the unlicensed spectrum cell, the reference cell is the authorized spectrum cell; and the second determining module 32 is configured to determine the unlicensed spectrum according to the reference timing. The SFN and the subframe number on the cell; and determining the location of the periodic resource on the unlicensed spectrum cell according to the SFN, the subframe number, and the preset periodic resource parameter; the transceiver module 30 is further used in the A periodic resource is transmitted to the base station at a location of the periodic resource, where the location of the periodic resource is a specific resource transmission time.

Specifically, the transceiver module 30 receives the notification message sent by the base station, which may be from the perspective of the authorized spectrum cell, that is, the UE determines the time when the notification message is received by using the authorized spectrum cell as a reference, and the transceiver module 30 receives the notification at the TO time. The message, the TO time actually corresponds to the start time corresponding to a certain subframe on a certain radio frame on the licensed spectrum cell. The foregoing notification message may be a Radio Resource Control (RRC) message, or may be a Media Access Control (MAC) layer message. It may be a physical layer (Physical, hereinafter referred to as PHY) message, and may also be a dedicated message for notifying a specific UE, or may be a multicast message or a broadcast message for notifying a group of UEs or all UEs. The form is not limited.

It should be noted that, when the time when the transceiver module 30 receives the notification message corresponds to a different cell, the corresponding radio frame and the subframe are different. Therefore, the transceiver module 30 passes the first determination before receiving the notification message. The module 31 and the base station agree in advance which cell is a time reference, that is, the reference cell is previously agreed with the base station. And the base station and the UE agree to the reference cell in advance, and the corresponding configuration message is transmitted between the base station and the UE, and the reference cell is mutually agreed by the configuration message; or the reference cell is specified in the protocol, and the base station and the UE are all specified according to the protocol. The reference cell determines the reference timing.

Taking FIG. 2 as an example, it is assumed that the transceiver module 30 receives the notification message sent by the base station on the SFN=0 of the reference cell and the subframe number=2 (ie, the third subframe of the first radio frame), then the first determination is performed. The module 31 determines the start time corresponding to the third subframe (assumed to be the TO time described above) as the reference timing available to the unlicensed spectrum cell.

After the first determining module 31 determines the TO time as the reference timing, the second determining module 32 corresponds the TO time to the unlicensed spectrum cell, that is, determines the SFN and the subframe number on the unlicensed spectrum cell corresponding to the reference timing, According to FIG. 2, the SFN=0 on the unlicensed spectrum cell corresponding to the reference timing, and the subframe number=0 (ie, the first subframe of the first radio frame).

The base station sends the configured periodic resource parameter to the UE in advance, and the periodic resource parameter is used to determine the location of the periodic resource transmitted between the base station and the UE. Optionally, the periodic resource may be a downlink reference signal CRS, and/or an uplink reference signal SRS, and/or an uplink SR, and/or an uplink CQI reporting resource, where the periodic resource parameter includes a periodic resource. The period of occurrence (that is, how many ms each appears), the offset (along with the period, used to determine which subframe the periodic resource appears on), the location of the frequency resource, and so on. The second determining module 32 determines, according to the determined SFN, the subframe number, and the periodic resource parameter on the unlicensed spectrum cell, the location of the periodic resource on the unlicensed spectrum cell, where the location is specific to the periodic resource transmission. The UE transmits the corresponding periodic resource to the base station at the periodic resource location by the transceiver module 30, so that the UE and the base station only perform data transmission, decoding, and the like at the time of periodic resource transmission. The unlicensed spectrum cell is available at the time of the periodic resource transmission determined by the embodiment of the present invention, so that the UE and the base station are prevented from being unavailable in the unlicensed spectrum cell. At the same time, the problem of decoding and transmitting data by using periodic resources is still adopted, and the communication quality is improved. In addition, the reference timing determined by the foregoing first determining module 31 may also be used for the calculation of the scheduling timing, the HARQ timing, the random access procedure timing, the DRX timing, the semi-static scheduling SPS resources, and the like, which are not described herein again.

The user equipment provided by the embodiment of the present invention receives, by the transceiver module, a notification sent by the base station for notification.

The first determining module determines, according to the notification message and the pre-agreed reference cell, a reference timing that is available to the unlicensed spectrum cell, and the second determining module determines, according to the reference timing, the unlicensed spectrum cell. SFN and the subframe number, and finally determining the location of the periodic resource on the unlicensed spectrum cell according to the determined SFN, the subframe number, and the preset periodic resource parameter, and transmitting the periodic resource to the base station at the location by the transceiver module . The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The quality of user communication.

Specifically, if the notification message does not include the start time available to the unlicensed spectrum cell, the notification message sent by the base station to the UE is actually notifying the UE that the current unlicensed spectrum cell is currently available, and the first determining module 31 may receive the message. The time to the notification message is determined as the reference timing; if the notification message includes the start time available to the unlicensed spectrum cell, the base station sends a notification message to the UE, which may be a moment to inform the UE that the notification message will be received by the first determining module 31. Determining as reference timing, and further informing when the unlicensed spectrum cell starts to be available; or instructing the UE to use the start time of the unlicensed spectrum cell by the first determining module 31 as the reference timing, the reference timing and the unlicensed spectrum cell The available starting moments are actually the same. As for the case where the notification message includes the start time available to the unlicensed spectrum cell, the first determining module 31 uses the time when the notification message is received as the reference timing or the start time of the unlicensed spectrum cell as the reference timing. It can be implemented by a rule that the base station and the UE agree on the reference timing.

On the basis of the foregoing embodiment, as a first feasible implementation manner of the embodiment of the present invention, the embodiment relates to that the transceiver module 30 receives the notification message sent by the base station at the first moment in the reference cell, and the first determination is performed. Module 31 determines the specific process of reference timing. further, The transceiver module 30 is configured to receive the notification message sent by the base station at the first time in the reference cell. The first determining module 31 is specifically configured to use the first time as the reference timing of the unlicensed spectrum cell. .

Specifically, the reference cell in this embodiment may be previously agreed by the base station and the UE, or may be specified by the protocol, that is, the cell where the UE receives the notification message is used as the reference cell, and the cell may be the primary cell, or may be Other auxiliary cells. If the transceiver module 30 receives the notification message sent by the base station at the first time of the reference cell, the first time may be a start time corresponding to a certain subframe of the reference cell, and may also be a certain radio frame of the reference cell. The starting time corresponding to a certain subframe. Here are two simple examples. The reference cells in both examples are the primary cells, that is, the transceiver module 30 receives the notification message in the primary cell:

Example 1: When the transceiver module 30 receives the notification message that informs the UE that the unlicensed spectrum cell is available when the subframe number of the primary cell is 2 (see FIG. 2 for example), the first determining module 31 determines the primary cell subframe. The start time corresponding to the subframe of number=2 is the start of the timing available for the unlicensed spectrum cell, that is, as the reference timing available to the unlicensed spectrum cell, and the second determining module 32 corresponds the reference timing to the unlicensed spectrum cell. The SFN and the subframe number corresponding to the reference timing are determined on the unlicensed spectrum cell (the corresponding SFN=0 in FIG. 2, the subframe number=0), that is, the available start time of the unlicensed spectrum cell is the self SFN. =0, subframe with subframe number=0. Finally, the second determining module 32 determines the location of the periodic resource according to the SFN, the subframe number, and the preset periodic resource parameter, and transmits the periodic resource to the base station at the location of the periodic resource by the transceiver module 30, for example, And may be a periodic receiving measurement CRS, or may be a periodic receiving CSI-RS, or may send a CQI on a periodic CQI resource, send an SRS on a periodic SRS resource, and send a SR by using a periodic SR resource. Wait. Optionally, the base station may further notify the UE of the duplex mode of the unlicensed spectrum cell, such as FDD, TDD, where FDD may also notify FDD DL Only or FDD UL Only, where TDD may also include TDD. The uplink and downlink ratios are used to enable the second determining module 32 to better determine the location of the periodic resources.

Example 2: When the transceiver module 30 receives the notification message that the unlicensed spectrum cell is available when the primary cell SFN=0 and the subframe number=1, the UE determines that the primary cell SFN=0, the subframe number=1 corresponds to The start time is used as the start of the timing of the unlicensed spectrum, that is, as the reference timing available to the unlicensed spectrum cell, and the second determining module 32 associates the reference timing to the unlicensed spectrum cell, and determines the unlicensed spectrum cell. The SFN and the subframe number corresponding to the reference timing (where the SFN continues to use the parameters) SFN=0 in the test cell. That is, if the second determining module 32 determines the SFN number on the reference cell when receiving the notification message, the second determining module 32 can directly use the reference cell when determining the SFN number on the corresponding unlicensed spectrum cell. SFN number.

The user equipment provided by the embodiment of the present invention receives, by the transceiver module, a notification message sent by the base station to notify the UE that the unlicensed spectrum cell is available, at the first moment of the reference cell, and the first determining module determines the first moment as the unlicensed spectrum cell. The available reference timing, the second determining module determines the SFN and the subframe number on the unlicensed spectrum cell according to the reference timing, and finally determines the unlicensed spectrum cell according to the determined SFN, the subframe number, and the preset periodic resource parameter. The location of the periodic resource, and the periodic resource is transmitted to the base station by the transceiver module at the location. The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available.

On the basis of the foregoing embodiment, as a second feasible implementation manner of the embodiment of the present invention, the embodiment relates to that the transceiver module 30 receives the notification message sent by the base station at the second moment in the non-reference cell, first. The determination module 31 determines the specific process of the reference timing. Further, the transceiver module 30 is configured to receive the notification message sent by the base station at a second time in the non-reference cell. The first determining module 31 is specifically configured to use the second moment Corresponding to the first moment in the reference cell; and using the first moment as a reference timing available to the unlicensed spectrum cell.

If the transceiver module 30 receives the notification message sent by the base station at the second time of the non-reference cell, the second time may be a start time corresponding to a certain subframe of the non-reference cell, and may also be a certain non-reference cell. The starting moment corresponding to a certain subframe on a radio frame. The first determining module 31 corresponds to the second time when the notification message is received to the reference cell (the same time corresponds to a different cell, and the corresponding subframe or radio frame is different), the second moment Corresponding to the first moment in the reference cell, the first determining module 31 determines that the first moment of the reference cell is unlicensed Reference timing of the weight spectrum cell. Afterwards, the second determining module 32 corresponds the reference timing to the unlicensed spectrum cell, and determines the SFN and the subframe number corresponding to the reference timing on the unlicensed spectrum cell, and according to the SFN, the subframe number, and the preset period. The resource parameter determines the location of the periodic resource, and transmits the periodic resource to the base station at the location of the periodic resource by the transceiver module 30, for example, may be a periodic receiving measurement CRS, or may be a periodic receiving CSI- The RS may also send the CQI on the periodic CQI resource, send the SRS on the periodic SRS resource, and send the SR by using the periodic SR resource. Optionally, the base station may further notify the UE of the duplex mode of the unlicensed spectrum cell, such as FDD and TDD. In the case of FDD, the FDD DL Only or FDD UL Only may also be notified, where the TDD may also include the TDD. The uplink and downlink ratios are used to enable the second determining module 32 to better determine the location of the periodic resources.

In addition, whether it is the first feasible implementation manner of the embodiment of the present invention or the second feasible implementation manner, the content of the notification message received by the transceiver module 30 may still be an unlicensed spectrum cell available, an unlicensed spectrum cell. At least one of an available start time, an available end time of the unlicensed spectrum cell, and an available time length of the unlicensed spectrum cell, except that the base station and the UE agree that the receiving moment of receiving the notification message is corresponding to the reference cell. And the time corresponding to the reference cell is used as the reference timing available for the unlicensed spectrum cell.

The user equipment provided by the embodiment of the present invention receives, by the transceiver module, a notification message sent by the base station to notify the UE that the unlicensed spectrum cell is available, at the second moment of the non-reference cell, and the first determining module corresponds the second time to the reference cell. And determining, by the first moment, a reference timing that is available to the unlicensed spectrum cell, the second determining module determines, according to the reference timing, the SFN and the subframe number on the unlicensed spectrum cell, and finally, according to the determined SFN, The subframe number and the preset periodic resource parameter determine the location of the periodic resource on the unlicensed spectrum cell, and transmit the periodic resource to the base station at the location by the transceiver module. The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The quality of user communication.

On the basis of the foregoing embodiment, as a third feasible implementation manner of the embodiment of the present invention, the embodiment relates to the first determining module 31 as the non-authorized start time of the unlicensed spectrum cell in the notification message. The specific process of reference timing available to the spectrum cell. Further, the foregoing first determining module 31 is specifically configured to use, according to the reference cell, a start time that is available to the unlicensed spectrum cell in the notification message as a reference timing that is available to the unlicensed spectrum cell. Specifically, in the content of the notification message received by the transceiver module 30 in this embodiment, the start time of the unlicensed spectrum cell needs to be included, optionally, except that the start time of the unlicensed spectrum cell is available. And may further include at least one of an unlicensed spectrum cell available, an end time available for the unlicensed spectrum cell, and an available length of the unlicensed spectrum cell, but only the base station and the UE agree to use the unlicensed spectrum cell in the notification message. The start time is used as the reference timing available for the unlicensed spectrum cell. Therefore, the base station may specify, according to the reference cell that is previously agreed with the UE, a start time corresponding to a certain subframe in the reference cell as a start time available for the unlicensed spectrum cell, and the unlicensed spectrum cell is used. The available start time is carried in the notification message and sent to the UE. It should be noted that the receiving and receiving module 30 may receive the notification message in the non-reference cell at this time, or may receive in the reference cell, as long as the finally determined reference timing is available in the unlicensed spectrum cell in the notification message. The starting time is correct.

The first determining module determines the start time available for the unlicensed spectrum cell in the notification message as the reference timing available to the unlicensed spectrum cell, and the second determining module determines the non-determination according to the reference timing. Authorizing the SFN and the subframe number on the spectrum cell, and finally determining the location of the periodic resource on the unlicensed spectrum cell according to the determined SFN, the subframe number, and the preset periodic resource parameter, and using the transceiver module at the location The base station transmits periodic resources. The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The quality of user communication.

On the basis of the above-mentioned embodiments, the fourth feasible embodiment of the present invention is an implementation manner. The embodiment relates to the second determining module 32 determining the SFN and the subframe number on the unlicensed spectrum cell according to the reference timing. Specific process. Further, the transceiver module 30 is further configured to: before receiving the notification message sent by the base station, receive a timing reference indication sent by the base station; and the second determining module 32 is specifically configured to: in the unlicensed spectrum cell according to the timing reference indication The SFN and the subframe number corresponding to the reference timing are determined.

Specifically, the transceiver module 30 notifies the second determining module 32 when receiving the timing reference indication sent by the base station, and the second determining module 32 performs the unlicensed spectrum according to the timing reference indication and the reference timing determined by the previous first determining module 31. The SFN and the subframe number corresponding to the reference timing are determined on the cell. The timing reference indication is used to indicate to the UE that the second determining module 32 should set the determined reference The SFN and the subframe number are converted to, because the SFN and the subframe number on the unlicensed spectrum cell determined by the second determining module 32 according to the same reference timing may be different according to the timing reference indication. The example shown in FIG. 2 above is a manner in which the second determining module 32 determines the SFN and the subframe number of the unlicensed spectrum cell according to the reference timing (the determined SFN=0, the subframe number=0), and may also have Other ways to determine the SFN and subframe number of the unlicensed spectrum cell, that is, Figures 2 and 3 determine different SFN and subframe numbers with the same reference timing.

Referring to FIG. 3, the reference cell is a primary cell. When the transceiver module 30 receives a notification message indicating that the unlicensed spectrum cell is available when the primary cell subframe number=2, the first determining module 31 determines that the primary cell subframe number=0 corresponds. The start time is the start of the timing available for the unlicensed spectrum cell, that is, the reference timing available as the unlicensed spectrum cell; the second determining module 32 corresponds the reference timing to the SFN=0 on the unlicensed spectrum cell, The frame number=2, and the unlicensed spectrum cell corresponding to the subframe with the subframe number=0 and the subframe number=1 cannot be used. From the subframe after the subframe number=1, the unlicensed spectrum cell can be used; that is, The first determining module 31 determines the start time corresponding to the SFN=0 and the subframe number=2 on the reference cell as the reference timing available to the unlicensed spectrum cell, and uses SFN=0 and the subframe number=2 to be unauthorized. On the spectrum cell, the SFN=0, the subframe number=2, BP determined by the second determining module 32, the timing of the unlicensed spectrum cell is completely synchronized with the timing of the reference cell, including the SFN and the subframe number, only from When the cell is known unlicensed spectrum spectrum resources available, in order to use unlicensed spectrum cell.

It should be noted that the second determining module 32 determines, according to the same reference timing, what SFN and subframe number, that is, the timing reference indication is specific, and may be configured by the base station for the UE, or the base station and the UE agree.

Further, the second determining module 32, after determining the SFN and the subframe number of the unlicensed spectrum cell (whether determining which SFN and subframe number are determined), the second determining module 32 may further according to the SFN, the subframe number, and The preset DRX parameter determines the activation or shutdown timing of the DRX of the UE on the unlicensed spectrum cell to save the power consumption of the UE. Optionally, the DRX parameter may be a DRX cycle, such as: a long DRX cycle, a short DRX cycle, a routine activation time (On durat ion) timer, a routine activation time start offset, or a non- The activation timer is also a parameter such as a retransmission timer. The DRX parameter is not limited in the embodiment of the present invention, as long as it can be combined with the SFN and the subframe number of the unlicensed spectrum cell determined by the second determining module 32. The UE's DRX activation or shutdown time is sufficient. The user equipment provided by the embodiment of the present invention receives, by the transceiver module, a notification sent by the base station for notification.

The first determining module determines a start time available for the unlicensed spectrum cell in the notification message as a reference timing that is available to the unlicensed spectrum cell, and the second determining module combines the base station according to the reference timing. Configuring a timing reference indication to the UE, determining an SFN and a subframe number on the unlicensed spectrum cell, and finally determining a location of the periodic resource on the unlicensed spectrum cell according to the determined SFN, the subframe number, and the preset periodic resource parameter. And transmitting periodic resources to the base station at the location through the transceiver module. The user equipment provided by the embodiment of the present invention improves the data correctness rate and improves the data at the time of the determined periodic resource transmission, and performs decoding and transmission of data according to the periodic resource, only when the unlicensed spectrum cell is available. The user communication quality is determined; and the DRX activation or shutdown time of the UE is determined by the determined SFN and subframe number on the unlicensed spectrum cell and the preset DRX parameter, thereby saving power consumption of the UE.

FIG. 6 is a schematic structural diagram of Embodiment 2 of a base station according to the present invention. As shown in FIG. 6, the base station includes: a transmitting module 40 and an appointment module 41. The sending module 40 is configured to send a periodic resource parameter to the UE, and the confusing module 41 is configured to allocate a reference cell with the UE, where the reference cell determines, for the UE, the available time of the unlicensed spectrum cell. The reference cell is a licensed spectrum cell, and the sending module 40 is further configured to send a notification message to the UE, where the notification message is used to notify the UE that the unlicensed spectrum cell is available, so that the UE is used. Determining a reference timing of the unlicensed spectrum cell according to the notification message and the reference cell, and determining a location of the periodic resource according to the reference timing and the periodic resource parameter, where the periodic resource A periodic resource is transmitted with the base station at a location.

Specifically, the sending module 40 sends a periodic resource parameter to the UE, where the periodic resource parameter is used to determine the location of the periodic resource transmitted between the base station and the UE. Optionally, the periodic resource may be a downlink reference signal CRS, and/or an uplink reference signal SRS, etc., where the periodic resource parameter includes a period in which periodic resources occur (ie, how many ms each subframe appears on) ), offset, frequency resource location, etc. In addition, the confession module 41 pre-associates a reference cell with the UE, and the reference cell determines, for the UE, a time reference available to the unlicensed spectrum cell, where the reference cell is an authorized spectrum cell; and, the appointing module 41 and the UE agree in advance that the reference cell may be a base station and The corresponding configuration message is transmitted between the UEs, and the reference cell is mutually agreed by the configuration message, and the reference cell may be specified in the protocol.

The sending module 40 sends a notification message to the UE, where the notification message is used to notify the UE of the unlicensed spectrum. The cell is available; the UE receives the notification message, and the UE receives the notification message, which may be from the perspective of the licensed spectrum cell, that is, the UE uses the authorized spectrum cell as a reference (ie, one of the authorized spectrum cells as the reference cell) to determine that the notification message is received. Moment. It is assumed that the UE receives the notification message at the time of the TO, and the TO time actually corresponds to the start time corresponding to a certain subframe on a certain radio frame on the reference cell. The foregoing notification message may be an RRC message, may also be a MAC layer message, may also be a PHY message, may also be a dedicated message for notifying a specific UE, or may be a multicast message or a broadcast message for notifying a group of UEs or all UEs. The embodiment of the present invention does not limit the form of the notification message.

It should be noted that, if the time when the UE receives the notification message corresponds to a different cell, the corresponding radio frame and the subframe are different. Therefore, the agreement module 41 and the UE agree in advance to refer to the purpose of the cell, in order to enable The UE corresponds to the time when the notification message is received to a fixed reference cell.

As shown in FIG. 2, it is assumed that the UE receives the notification message sent by the sending module 40 when the SFN=0 of the reference cell and the subframe number=2 (ie, the third subframe of the first radio frame), the UE will The start time corresponding to the third subframe (assumed to be the TO time) is determined as the reference timing available to the unlicensed spectrum cell, and the TO time is corresponding to the unlicensed spectrum cell, that is, the unlicensed spectrum corresponding to the reference timing is determined. The SFN and the subframe number on the cell, as shown in FIG. 2, the SFN=0 on the unlicensed spectrum cell corresponding to the reference timing, and the subframe number=0 (ie, the first subframe of the first radio frame).

The base station provided by the embodiment of the present invention allocates a reference cell to the UE through the contracting module, and sends a notification message and a periodic resource for notifying the unlicensed spectrum cell of the UE to the UE through the sending module. And determining, by the UE, a reference timing that is available to the unlicensed spectrum cell according to the notification message and the reference cell, and determining a location of the periodic resource according to the reference timing and the periodic resource parameter, where the periodic resource is transmitted with the UE. . The base station provided by the embodiment of the present invention enables the UE to improve the accuracy of the data when the unlicensed spectrum cell is available, and the data is decoded and transmitted according to the periodic resource at the time of the determined periodic resource transmission. Further, the user communication quality is improved. Further, based on the foregoing embodiment, the notification message may include an unlicensed spectrum cell available, a start time available for the unlicensed spectrum cell, an end time available for the unlicensed spectrum cell, and an unlicensed spectrum cell. At least one of the length of time available.

Specifically, if the notification message sent by the sending module 40 to the UE does not include the start time available to the unlicensed spectrum cell, the notification message sent by the sending module 40 to the UE actually informs the UE that the current unlicensed spectrum cell is currently available. The UE may determine the time when the notification message is received as the reference timing. If the notification message includes the start time available to the unlicensed spectrum cell, the sending module 40 sends a notification message to the UE, which may be to inform the UE that the notification message will be received. The time is determined as the reference timing, and further informs the unlicensed spectrum cell when it is available. It may also be that the UE is informed of the available start time of the unlicensed spectrum cell as the reference timing, and the reference timing and the available start time of the unlicensed spectrum cell are available. It's actually the same. As for the case where the notification message includes the start time available to the unlicensed spectrum cell, whether the UE uses the time when the notification message is received as the reference timing or the start time of the unlicensed spectrum cell as the reference timing can be adopted by the appointment module. 41 is implemented with the UE's convention of reference timing. Specifically, there are three implementation methods:

The reference cell here may be previously agreed by the agreement module 41 and the UE, or may be specified by the protocol, that is, the cell in which the UE receives the notification message is used as the reference cell, and the cell may be the primary cell or other auxiliary cells. . If the UE receives the notification message sent by the base station at the first time of the reference cell, the first time may be a start time corresponding to a certain subframe of the reference cell, and may also be a certain radio frame of the reference cell. The starting time corresponding to one subframe. Here are two simple examples. The reference cells in both examples are the primary cells, that is, the UE receives the notification message in the primary cell:

Example 1: When the UE receives the notification message sent by the sending module 40 to notify the UE that the unlicensed spectrum cell is available when the subframe number of the primary cell is 2 (see the example of FIG. 2), the UE determines the child of the primary cell. The start time corresponding to the subframe of the frame number=2 is used as the start of the available timing of the unlicensed spectrum cell, that is, as the reference timing available to the unlicensed spectrum cell, and the reference timing is corresponding to the unlicensed spectrum cell. The SFN and the subframe number corresponding to the reference timing are determined on the unlicensed spectrum cell (the corresponding SFN=0 in FIG. 2, the subframe number=0), that is, the available start time of the unlicensed spectrum cell is its own SFN=0, Subframe with subframe number = 0. Finally, the UE determines the location of the periodic resource according to the SFN, the subframe number, and the preset periodic resource parameter, and transmits the periodic resource to the base station at the location of the periodic resource, for example, may be a periodic receiving measurement. The CRS may also be a periodic CSI-RS, or may send a CQI on a periodic CQI resource, send an SRS on a periodic SRS resource, and send an SR using a periodic SR resource. Optionally, the base station may further notify the UE of the duplex mode of the unlicensed spectrum cell, such as FDD, TDD. In the case of FDD, the FDD DL Only or the FDD UL Only may also be notified; where the TDD may also include the TDD. The uplink and downlink ratios are used to enable the UE to better determine the location of the periodic resources.

Example 2: When the UE receives the notification message sent by the sending module 40 to notify the unlicensed spectrum cell that the primary cell SFN=0 and the subframe number=1, the UE determines that the primary cell SFN=0, the subframe number= Corresponding start time is used as the start of the timing of the unlicensed spectrum, that is, as a reference timing available to the unlicensed spectrum cell, and the reference timing is corresponding to the unlicensed spectrum cell, and is determined on the unlicensed spectrum cell. The SFN and the subframe number corresponding to the reference timing (where the SFN continues to use SFN=0 in the reference cell). That is, if the UE determines the SFN number on the reference cell when receiving the notification message, the SFN number on the reference cell can be directly used when determining the SFN number on the corresponding unlicensed spectrum cell.

If the UE receives the notification message sent by the sending module 40 at the second time of the non-reference cell, the second time may be a start time corresponding to a certain subframe of the non-reference cell, and may also be a certain non-reference cell. The starting moment corresponding to a certain subframe on a radio frame. The UE then corresponds to the second time when the notification message is received to the reference cell (the same time corresponds to a different cell, and the corresponding subframe or radio frame is different), and the second time is in the reference cell. First moment And determining, by the first moment of the reference cell, a reference timing of the unlicensed spectrum cell. after that,

The UE determines the reference timing to the unlicensed spectrum cell, determines the SFN and the subframe number corresponding to the reference timing on the unlicensed spectrum cell, and determines the periodicity according to the SFN, the subframe number, and the preset periodic resource parameter. The location of the resource, and the periodic resources are transmitted with the base station at the location of the periodic resource.

In addition, whether in the foregoing first implementation manner or the second manner, the content in the notification message received by the UE may still be an unlicensed spectrum cell available, an initial time available for the unlicensed spectrum cell, and an unlicensed spectrum cell available. At least one of the ending time and the length of time that the unlicensed spectrum cell is available, only the appointment module 41 and the UE agree that the receiving moment of receiving the notification message may be corresponding to the reference cell, and corresponding to the reference cell. The time is used as the reference timing available to the unlicensed spectrum cell.

Optionally, the notification message may include, in addition to the start time available for the unlicensed spectrum cell, an unlicensed spectrum cell available, an end time available for the unlicensed spectrum cell, and at least one of the available lengths of the unlicensed spectrum cell. For example, only the initial time that the agreement module 41 and the UE agree to use the unlicensed spectrum cell in the notification message is used as the reference timing available for the unlicensed spectrum cell. Therefore, before the appointment module 41, the start time corresponding to a certain subframe in the reference cell is specified as the initial time available for the unlicensed spectrum cell according to the reference cell agreed with the UE in advance, and The start time available to the unlicensed spectrum cell is carried in the notification message and sent to the UE by the sending module 40.

The base station provided by the embodiment of the present invention sends a notification message and a periodic resource parameter for notifying the unlicensed spectrum cell of the UE to the UE through the prancing module and the agreed reference cell, and the UE sends the notification message and the periodic resource parameter to the UE according to the notification message and the reference cell. Determining a reference timing available to the unlicensed spectrum cell, and determining a location of the periodic resource according to the reference timing and the periodic resource parameter, where the periodic resource is transmitted with the UE. The base station provided by the embodiment of the present invention enables the UE to improve the accuracy of the data when the unlicensed spectrum cell is available, and the data is decoded and transmitted according to the periodic resource at the time of the determined periodic resource transmission. Improve the quality of user communication.

Based on the foregoing embodiment, further, the embodiment relates to the sending module 40. Before transmitting the notification message to the UE, sending a timing reference indication to the UE, so that the UE determines a specific process of the SFN and the subframe number available to the unlicensed spectrum cell according to the timing reference indication.

Specifically, after receiving the timing reference indication sent by the sending module 40, the UE determines the SFN and the subframe number corresponding to the reference timing on the unlicensed spectrum cell according to the timing reference indication and the reference timing determined by the previous UE. The timing reference indication is used to indicate to the UE how the SFN and the subframe number should be converted into the determined reference timing, because the SFN and the child on the unlicensed spectrum cell determined by the UE according to the same reference timing are different according to the timing reference indication. The frame number can be different. The example shown in FIG. 2 above is one way for the UE to determine the SFN and the subframe number of the unlicensed spectrum cell according to the reference timing (the determined SFN=0, the subframe number=0), and there may be other manners. The SFN and the subframe number of the unlicensed spectrum cell are determined, that is, FIG. 2 and FIG. 3 determine different SFN and subframe numbers with the same reference timing.

Referring to FIG. 3, the reference cell is a primary cell. When the UE receives the notification message sent by the sending module 40 to notify the unlicensed spectrum cell that the UE sends the primary cell subframe number=2, the UE corresponds to the primary cell subframe number=0. The start time is determined as the start of the available timing of the unlicensed spectrum cell, that is, the reference timing available as the unlicensed spectrum cell, and the reference timing is corresponding to SFN=0 on the unlicensed spectrum cell, and the subframe number=2 The unlicensed spectrum cell corresponding to the subframe with the subframe number=0 and the subframe number=1 cannot be used, and the subframe from the subframe number=1 can be used by the unlicensed spectrum cell; that is, the UE will refer to the cell. The start time corresponding to the SFN=0 and the subframe number=2 is determined as the reference timing available to the unlicensed spectrum cell, and the SFN=0 and the subframe number=2 are applied to the unlicensed spectrum cell, that is, the unauthorized The timing of the spectrum cell is completely synchronized with the timing of the reference cell, including the SFN and the subframe number, and the unlicensed spectrum cell can be used only when the spectrum resource of the unlicensed spectrum cell is notified.

It should be noted that the UE determines the SFN and the subframe number according to the same reference timing, that is, the timing reference indication is specifically configured, and may be configured by the appointment module 41 for the UE, or the base station and the UE agree.

Further, before the sending module 40 sends the notification message to the UE, the agreement module 41 may further send the DRX parameter to the UE, so that the UE determines the SFN and the subframe number of the unlicensed spectrum cell (whether it is determined which SFN and the child are determined). The frame number is determined according to the SFN, the subframe number, and the preset DRX parameter, and the activation or shutdown timing of the DRX of the UE is determined on the unlicensed spectrum cell to save the power consumption of the UE. Optionally, the DRX parameter may be a DRX cycle, such as: a long DRX cycle, a short DRX cycle, a routine activation time (On durat ion) timer, or a routine activation time start bias. The shifting amount may also be an inactive timer, and may also be a parameter such as a retransmission timer. The DRX parameter is not limited in the embodiment of the present invention, as long as it can be combined with the SFN and the subframe number of the unlicensed spectrum cell determined by the UE. It is sufficient to determine the DRX activation or shutdown time of the UE.

The base station provided by the embodiment of the present invention allocates a reference cell to the UE through the contracting module, and sends a notification message and a periodic resource parameter for notifying the unlicensed spectrum cell of the UE to the UE by using the sending module, so that the UE according to the notification message and the reference The cell determines a reference timing that is available to the unlicensed spectrum cell, and determines an SFN and a subframe number on the unlicensed spectrum cell according to the reference timing and a timing reference indication sent by the sending module to the UE, and finally according to the determined SFN, the subframe number, and And the periodic resource parameter determines the location of the periodic resource, where the periodic resource is transmitted with the UE. The base station provided by the embodiment of the present invention enables the UE to improve the accuracy of the data when the unlicensed spectrum cell is available, and the data is decoded and transmitted according to the periodic resource at the time of the determined periodic resource transmission. The user communication quality is improved; and the DRX parameter is sent to the UE by the sending module, so that the UE determines the DRX activation or shutdown time of the UE according to the determined SFN and the subframe number and the DRX parameter on the unlicensed spectrum cell, thereby saving the UE's consumption.
