The embodiment of the present invention further provides a communication system, including the base station 500 described above, and the network side device 600.

A user equipment, a base station, a network side device, and a communication system according to an embodiment of the present invention are described in detail above with reference to FIG. 2 to FIG. 7. A method for data transmission according to an embodiment of the present invention will be described below with reference to FIG. 8 to FIG. .

FIG. 8 shows a schematic flow chart of a method 700 of data transmission in accordance with an embodiment of the present invention. The method 700 is performed by the UE, including: S701, the user equipment UE sends the first uplink data on the common enhanced dedicated channel common E-DCH resource. S702. When the first uplink data is sent and the common E-DCH resource is not released, the UE stops sending the DPCCH.

Therefore, the UE in the embodiment of the present invention sends the DPCCH and the uplink data to the common E-DCH resource allocated by the base station. When the uplink data is sent, the UE stops transmitting the DPCCH, which can reduce interference to other users in the cell, and can improve System capacity.

The method 700 may be applied to other states relative to the CELL_DCH state, for example, may include a CELL_FACH state, a Cell Paging Channel (CELL_PCH) state, and a UTRAN Registration Area Paging Channel (UTRAN Registration Area Paging Channel, The URA_PCH state, the idle ID state, and the like are described in the embodiment of the present invention by taking the CELL_FACH state as an example.

Specifically, when the UE needs to send uplink data, the UE applies for a common E-DCH resource to the base station, and the base station allocates a common E-DCH resource to the UE. The common E-DCH resource is used for the UE to perform uplink data transmission, and is reserved by the UE for a period of time. The length of time for retaining the common E-DCH resource is usually determined according to the data transmission time of the UE. During the period in which the common E-DCH resource is reserved, the UE may intermittently transmit data, that is, the UE may not have uplink data to be transmitted in one or more intervals of the time.

It should be understood that sending uplink data herein may be understood as that the UE sends uplink control information to the base station through an E-DCH Dedicated Physical Control Channel (E-DPCCH), or through E-DCH dedicated physical data. The E-DCH Dedicated Physical Data Channel (E-DPDCH) transmits uplink data to the base station or through the HS-DSCH dedicated physical control (uplink) channel (HS-DPCCH). Send upstream feedback of downlink data. The E-DCH is an Enhanced Dedicated Transport Channel, and the HS-DSCH is a High-Speed Downlink Shared Channel.

Specifically, the completion of the uplink data transmission in the present invention means that the UE does not perform any data transmission to the base station side, and may include that no data needs to be sent or retransmitted in the HARQ buffer of the UE, and may also include the UE on the HS-DPCCH. There is no uplink feedback that needs to be sent to the base station. Correspondingly, the sending of the first uplink data includes: the radio link control layer (RLC) of the UE and/or the media access control layer (MAC) cache is empty, and the hybrid automatic weight No uplink data needs to be transmitted or retransmitted in the Hybrid Automatic Repeat Request (HARQ) process, and the UE does not have a high-speed downlink shared channel HS-DSCH dedicated physical control channel HS-DPCCH to be transmitted; or there is no uplink data required in the HARQ process. Transmission or retransmission, and the UE does not need to transmit HS-DPCCH.

After acquiring the common E-DCH resource, the UE first sends the DPCCH on the common E-DCH resource. Then, the UE starts to send uplink data on the common E-DCH resource. When the uplink data transmission is completed, the UE stops transmitting the DPCCH. At the same time, when the UE retains the common E-DCH resource (ie, when the common E-DCH resource is not released), the base station reserves the common E-DCH resource for the UE even if the base station does not receive the DPCCH sent by the UE, that is, The base station does not release the common E-DCH resource reserved by the UE, that is, the base station still allows the UE to occupy the common E-DCH resource.

The stopping of the sending of the DPCCH by the UE may be performed according to the pre-established criteria of the UE and the base station, or may be stopped according to the indication of the network-side device, which is not limited in this embodiment of the present invention. Here, the UE and the base station agree to stop transmission in advance, and also includes a criterion that the network side device (for example, the RNC) separately informs the UE and the base station to stop the DPCCH transmission.

Therefore, the UE in the embodiment of the present invention obtains the common E-DCH resource from the base station, and sends the DPCCH and the uplink data on the common E-DCH resource. When the uplink data is sent, the UE stops transmitting the DPCCH, which can reduce other users in the cell. Interference can improve system capacity the amount.

Optionally, as an embodiment, the method 700 further includes: the UE receiving the indication information sent by the network side device, where the indication information is used to indicate that the UE sends the uplink data during the period of retaining the common E-DCH resource. Stop sending DPCCH. S702: When the first uplink data is sent and the common E-DCH resource is not released, the UE stops sending the DPCCH, and the UE sends, according to the indication information, that the first uplink data is sent and the common E-DCH resource is not When released, stop sending DPCCH.

Specifically, the UE may receive the indication information sent by the network side device, before the acquiring the common E-DCH resource, to indicate that the UE is in the period of retaining the common E-DCH resource, that is, when the common E-DCH resource is not released. When the first uplink data is sent, the transmission of the DPCCH is stopped. Specifically, the indication information is used to indicate that the UE can stop sending the DPCCH when the common E-DCH resource is reserved, and no uplink data needs to be sent, or is used to indicate that the UE starts the implicit resource release timer and mixes the automatic retransmission. When the request (Hybrid Automatic Repeat Request, HARQ) process has no data transmission, the DPCCH transmission is stopped. The UE stops transmitting control information on the DPCCH when the condition is met according to the indication information sent by the network side device. The control information includes a power control signal, a pilot signal, and the like, but the embodiment of the present invention is not limited thereto. In other words, after the UE completes the uplink data transmission, the UE stops transmitting the control information on the DPCCH during the period in which the UE continues to have the common E-DCH resource.

It should be noted that, after the UE uplink data is sent and the common E-DCH resource is not released, the UE does not satisfy the implicit resource release or the explicit resource release. That is, when the UE does not reach the condition of resource release, but the uplink data does not need to be sent, the UE stops transmitting the DPCCH. The implicit resource release here means that after the UE's buffer is empty for a period of time, the UE sends a release indication to the network side. The explicit resource release means that the base station or the RNC instructs the UE to release the current common E-DCH resource.

The UE receives the indication information sent by the network side device, and may receive the indication information that is sent by the network side device through the system broadcast, or may be the indication information that is sent by the network side device by using the Radio Resource Control (RRC) dedicated signaling. The RRC dedicated signaling may be signaling such as an RRC connection setup, a cell update confirm, a UTRAN registration area update (URA Update confirm), and the like. Not limited to this.

Preferably, as an embodiment, the UE receives the indication information sent by the network side device, and the packet The UE receives the indication information sent by the network side device through the system broadcast. In a specific example, the indication information can be carried in a system broadcast message. For example, the indication information may be carried by one bit of the system broadcast message. On the bit, “1” indicates that the indication information is carried, and “0” indicates that the indication information is not carried. The above is only one specific implementation of the embodiments of the present invention, and is not intended to limit the present invention.

Specifically, the UE may determine, according to the indication information on the network side, whether to stop transmitting the DPCCH when the uplink data is not to be sent. The indication information may be sent by the network side device in a system broadcast message. The UE receives the indication information, and during the period of retaining the common E-DCH resource, and when the uplink data transmission is completed, the DPCCH may be stopped according to the indication information.

Therefore, after ending the uplink data transmission on the common E-DCH resource, the UE in the embodiment of the present invention receives the indication information sent by the network side device, thereby stopping the transmission of the control information on the DPCCH, thereby reducing interference to other users in the cell. Can increase system capacity.

Optionally, as an embodiment, after the UE stops transmitting the DPCCH in S702, the method 700 further includes: determining, by the UE, second uplink data to be sent; before transmitting the second uplink data, the UE is in the common E- The transmission is restarted on the DCH resource; the UE transmits the second uplink data when the preset time after restarting the transmission of the DPCCH expires or within a certain time after the expiration.

Specifically, when the UE needs to perform uplink data transmission again, first determining the second uplink data to be sent (the data waiting to be sent in the buffer that the UE submits to the UE after stopping the DPCCH transmission may be different from the UE stopping sending. Another upstream data before DPCCH). Then, before transmitting the second uplink data, the UE restarts transmitting the DPCCH on the common E-DCH resource, that is, the UE sends control information such as a power control signal or a pilot signal on the DPCCH. After the time when the DPCCH preset is restarted, that is, the preset time after the control information is transmitted on the DPCCH expires or a certain period of time after the expiration, the second uplink data transmission is started. The preset time may be determined by the UE and the network side device, or may be a preset fixed value, for example, 2 time slots or 0 time slots, which is not limited in this embodiment of the present invention.

Optionally, the preset time may be different according to a time when the UE stops transmitting the DPCCH. For example, if the UE stops the DPCCH transmission for 20 ms before transmitting the second uplink data, the UE selects a shorter preset time; if the DPCCH transmission is stopped for 100 ms, the UE selects a longer preset time. The value of the preset time and the selected criterion that the UE can select may be set in the UE in advance, or may be sent to the UE by the network side, which is not used by the embodiment of the present invention. limited.

Optionally, in another embodiment, the method 700 further includes: the UE receiving a discontinuous transmission period and a discontinuous transmission offset sent by the network side device; the UE sending the resource discontinuously according to the discontinuous transmission period Offset, calculate the time when the DPCCH is restarted to be transmitted; the UE restarts transmitting the DPCCH at the time of the calculated retransmission of the DPCCH.

Specifically, the UE can obtain the time when the DPCCH is restarted when there is no uplink data transmission according to the following manner. When there is no uplink data transmission, the UE uses the following formula (1) to calculate a series of times (ie, the pattern pattern sent by the DPCCH) that needs to transmit the DPCCH:

((5*CFN–DTX_Offset+S)MOD DTX_cycle)=0 (1)

The DTX_cycle and the DTX_offset are respectively a discontinuous transmission period and a discontinuous transmission offset sent by the network side to the UE, and the MOD is a modulo operation. A series of CFN and S can be calculated by the above formula, where CFN is a Connection Frame Number and S is a subframe number in a connected frame. A series of CFNs and Ss form a series of transmission instants to form the transmit pattern of the DPCCH.

Therefore, the UE in the embodiment of the present invention obtains the common E-DCH resource from the base station, and sends the DPCCH and the uplink data on the common E-DCH resource. When the uplink data is sent, the UE stops transmitting the DPCCH, which can reduce interference to other users. Can increase system capacity.

The data transmission method of the embodiment of the present invention is described in detail from the perspective of the UE, and the data transmission method of the embodiment of the present invention is described in detail below from the perspective of the base station.

FIG. 9 shows a schematic flow diagram of a method 800 of data transmission in accordance with an embodiment of the present invention. The method 800 is performed by a base station, including: S801, the base station allocates a common enhanced dedicated channel common E-DCH resource to the UE; S802, the base station receives uplink data sent by the UE on the common E-DCH resource; S803, when detecting the When the UE stops transmitting the dedicated physical control channel DPCCH when the UE transmits the uplink data and the common E-DCH resource is not released, the base station reserves the common E-DCH resource for the UE.

Specifically, when the UE needs to send uplink data, the UE applies for a common E-DCH resource to the base station, and the base station allocates a common E-DCH resource to the UE according to the application of the UE. The common E-DCH The resource is used for the UE to perform uplink data transmission, and is reserved by the UE for a period of time. The length of time for retaining the common E-DCH resource is usually determined by the base station according to the data transmission time of the UE. During the period in which the common E-DCH resource is reserved, the UE may intermittently transmit data, that is, the UE may not have uplink data to be transmitted in one or more intervals of the time.

The base station receives the uplink data sent by the UE on the common E-DCH resource. Since the uplink data sent by the UE during the period of retaining the common E-DCH resource may be intermittent, when the base station detects that the UE sends the uplink data and the common E-DCH resource is not released, the base station reserves the DPCCH for the UE. The common E-DCH resource. That is, the base station does not release the common E-DCH resource reserved by the UE even if the base station does not receive the DPCCH sent by the UE, that is, the base station still allows the UE to occupy the common E-DCH resource.

Therefore, after the base station of the embodiment of the present invention allocates the common E-DCH resource to the UE, it receives the uplink data sent by the UE on the common E-DCH resource, and stops detecting the transmission of the uplink data when the UE stops transmitting the DPCCH. The base station still reserves the common E-DCH resource for the UE, and does not affect the use effect of the UE in the connected state while improving the cell capacity.

Optionally, as an embodiment, the method 800 further includes: the base station receiving the indication information sent by the network side device, where the indication information is used to notify the base station that the UE sends the uplink data during the period of retaining the common E-DCH resource. When the DPCCH is stopped when the UE sends the uplink data and the common E-DCH resource is not released, the base station reserves the common E-DCH resource for the UE, including: the base station according to the base station The indication information, when detecting that the UE sends the uplink data and the common E-DCH resource is not released, stops the sending of the DPCCH, and reserves the common E-DCH resource for the UE. Specifically, the network side device may send the indication information to the base station, and notify the UE of the information that stops transmitting the DPCCH when the uplink data is transmitted while the UE is transmitting the common E-DCH resource. In order to inform the base station UE that DPCCH transmission is not performed during the period of retaining the common E-DCH resource. After receiving the above information, the base station may not perform detection, or may not release the resources on the side when the control information is not detected on the DPCCH.

Preferably, the base station receives the indication information sent by the network side device, including: the base station receiving network The indication information sent by the network side device through the high speed downlink shared channel frame type two HS-DSCH Frame Type 2.

Specifically, after the UE obtains the common E-DCH resource allocated by the base station, the network side device may send the indication information to the base station by using a frame protocol. For example, the above indication information is carried in the HS-DSCH Frame Type 2 for transmission. In a specific example, the indication information may be carried by one bit in the HS-DSCH Frame Type 2. For example, the indication information may be carried by one bit of the HS-DSCH Frame Type 2, where "1" indicates that the indication information is carried, and "0" indicates that the indication information is not carried. The above is only one specific implementation of the embodiments of the present invention, and is not intended to limit the present invention. Alternatively, before the UE obtains the common E-DCH resource allocated by the base station, the network side device may send the foregoing indication information to the base station by means of signaling, which is not limited in this embodiment of the present invention.

The data transmission method of the embodiment of the present invention is described in detail below from the perspective of the network side device in conjunction with FIG. FIG. 10 shows a schematic flow diagram of a method 900 of data transmission in accordance with an embodiment of the present invention. The method 900 includes: S901, the network side device sends first indication information to the user equipment UE, where the first indication information is used to indicate that the UE stops transmitting when the uplink data is sent during the period of retaining the common enhanced dedicated channel common E-DCH resource. Dedicated physical control channel DPCCH; S902, the network side device sends second indication information to the base station, where the second indication information is used to notify the base station to stop when the UE sends the uplink data during the period of retaining the common E-DCH resource When the DPCCH is sent, the common E-DCH resource is reserved for the UE.

The network side device may send indication information to the UE and the base station respectively before the UE acquires the common E-DCH resource from the base station. The network side device sends the indication information to the UE, to indicate that the UE stops transmitting the DPCCH when the uplink data is sent during the period of retaining the common E-DCH resource. Optionally, the network side device sends the indication information to the UE, and may send the message to the UE by using a system broadcast message.

The network side device sends the indication information to the base station, to notify the base station UE to stop sending the DPCCH when the uplink data is sent during the period of retaining the common E-DCH resource. Optionally, the network side device may send the indication information to the base station by using the signaling manner to notify the base station that the UE is in the period of retaining the common E-DCH resource, before the UE obtains the common E-DCH resource allocated by the base station. When the uplink data is sent, you can stop sending the DPCCH. The network side device sends the indication information to the base station, and may be sent by the high speed downlink shared channel frame HS-DSCH Frame Type 2 after the UE obtains the common E-DCH resource allocated by the base station. That is, the network side device notifies the UE to the base station by means of a frame protocol when the UE transmits the uplink data while maintaining the common E-DCH resource. In order to notify the base station UE that during the period of retaining the common E-DCH resource, the DPCCH transmission is not performed when the uplink data is transmitted. After receiving the above information, the base station may not perform detection, or may not release the resources on the side when the control information is not detected on the DPCCH.

Optionally, as an embodiment, the method 900 further includes: the network side device sending a discontinuous transmission period and a discontinuous transmission offset to the UE, so that the UE according to the discontinuous transmission period and the discontinuous transmission bias Set, calculate the time when the DPCCH is restarted. The specific implementations are described in the foregoing, and are not described herein again.

The method for data transmission in the embodiment of the present invention will be described below with a specific example.

Figure 11 shows a schematic flow diagram of a method 1000 of data transmission in accordance with one embodiment of the present invention. Method 1000 includes the following steps.

S1001: The network side device sends the indication information to the UE by using a system broadcast. The indication information is used to indicate that the UE stops transmitting the DPCCH when the uplink data is sent during the period of retaining the common E-DCH resource.

S1002: The UE acquires a common E-DCH resource from the base station.

S1003: The network side device sends a protocol frame HS-DSCH Frame Type2 to the base station, where The HS-DSCH Frame Type 2 notifies the base station that the UE stops transmitting the DPCCH when the uplink data is transmitted while the UE is transmitting the common E-DCH resource.

S1004: The UE sends a DPCCH on the common E-DCH resource.

S1005: The UE sends uplink data on the common E-DCH resource.

S1006: The UE stops transmitting the DPCCH when the uplink data transmission is completed.

S1007: When the base station detects that the UE stops transmitting the DPCCH after transmitting the uplink data, the UE reserves the common E-DCH resource for the UE.

S1008: When the UE needs to perform uplink data transmission on the common E-DCH resource again, the UE determines other uplink data to be sent.

S1009: The UE restarts sending the DPCCH on the common E-DCH resource before transmitting other uplink data.

S1010: After restarting sending the DPCCH for a preset period of time, the UE performs uplink data transmission again.

Therefore, the UE in the embodiment of the present invention obtains the common E-DCH resource from the base station, and sends the DPCCH and the uplink data on the common E-DCH resource. When the uplink data is sent, the UE stops transmitting the DPCCH, which can reduce the other users of the cell. Interference can increase system capacity. And the network side device notifies the base station UE to stop sending the DPCCH when the uplink data is transmitted during the period of retaining the common E-DCH resource, so that the base station may not perform detection after receiving the foregoing notification, or does not detect the control information on the DPCCH. The resources on this side will be released.
