Description

Data transmission method, user equipment, base station, network side equipment and system

Technical Field

The embodiments of the present invention relate to the field of wireless communication, and in particular, to a method, a user equipment, a base station, a network side device, and a system for data transmission.

Background

With the third generation partnership project (the 3)^rdGeneration Partnership Project, 3GPP) applies a continuous enhancement to a Cell Forward Access Channel (Cell _ FACH) state in a standard, and a part of packet services originally required to be carried in a Cell Dedicated Channel (Cell _ DCH) state can also be carried in a Cell _ FACH state. The introduced common Enhanced Dedicated Channel (common E-DCH) characteristic enhances the uplink packet data transmission performance in the CELL _ FACH state, so that the uplink packet data transmission performance in the CELL _ FACH state obtains smaller packet transmission delay and higher transmission rate.

However, at present, data transmission of a packet service in the CELL _ FACH state is performed discontinuously, and data discontinuous transmission may be performed many times in one interactive process, and the user equipment UE maintains the same connection state and occupies the same resources regardless of whether data transmission exists. When the UE occupies resources and there is no data transmission, the Dedicated Physical Control Channel (DPCCH) for uplink continues to send Control information such as power Control and pilot signal, which may cause uplink interference to other users, so that the number of users in a connected state in the cell is limited, and thus the capacity of the cell is limited.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the invention can be applied to various communication systems, such as: global System for Mobile communications (GSM), Code Division Multiple Access (CDMA) System, Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (Long Term Evolution), and the like.

User Equipment (UE), which may also be referred to as a Mobile Terminal (Mobile Terminal), a Mobile User Equipment (ms), etc., may communicate with one or more core networks via a Radio Access Network (RAN, for example), and may be a Mobile Terminal, such as a Mobile phone (or a "cellular" phone) and a computer having a Mobile Terminal, such as a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile device, which exchange languages and/or data with the RAN, which is not limited by the present invention.

The Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, an evolved Node B (eNB or e-NodeB) in LTE, and the like, which is not limited in the present invention.

The Network side device may be a Radio Network Controller (RNC) in UMTS, or a combination of an RNC and a Base Station, or an eNB in LTE, or a Base Station Controller (BSC) in GSM, and the present invention is not limited thereto.

In current communication systems, data transmission of some services is performed intermittently, and intermittent transmission of data may be performed multiple times in a service processing procedure. For the UE in the CELL _ FACH state, when the UE sends uplink data, the UE transmits the uplink data through the obtained common E-DCH resource. After the UE acquires the common E-DCH resource, the UE retains the common E-DCH resource even if the UE does not perform transmission of uplink data for a period of time. Accordingly, while the UE retains the common E-DCH resource, the UE needs to transmit control information through a Dedicated Physical Control Channel (DPCCH), i.e., the UE needs to transmit DPCCH. Even if the UE does not transmit uplink data for a certain period of time, the UE continues to transmit control information such as a power control signal and a pilot signal on the DPCCH.

Specifically, as shown in fig. 1, at time t1, the UE acquires a common E-DCH resource, and releases the common E-DCH resource at time t2, that is, the time of the UE's holding of the common E-DCH resource is t2-t 1. The UE starts to transmit uplink data at time t3, and finishes transmitting uplink data at time t 4. the interval t4-t3 is within the time t2-t1, that is, the UE has a period of time for not performing uplink data transmission during the period of time (time t2-t 1) for holding the common E-DCH resource. However, the UE always occupies the DPCCH to send the control information, namely the UE always sends the DPCCH during the period of keeping the common E-DCH resource.

Here, sending uplink Data may be understood as UE sending uplink Control information to the base station through an E-DCH Dedicated Physical Control Channel (E-DPCCH), or sending uplink Data to the base station through an E-DCH Dedicated Physical Data Channel (E-DPDCH), or sending uplink feedback of downlink Data through a HS-DSCH Dedicated Physical Control (uplink) Channel (Dedicated Physical Control Channel (uplink) for HS-DSCH, HS-DPCCH). Wherein, the E-DCH is an Enhanced Dedicated Transport Channel (Enhanced Dedicated Transport Channel), and the HS-DSCH is a High-Speed Downlink Shared Channel (High-Speed Downlink Shared Channel).

In view of the above situation, the embodiment of the present invention performs the following improvements on the UE.

Optionally, as an embodiment, the user equipment 100 further includes: the determining module is used for determining second uplink data to be sent; a second sending module, configured to restart sending the DPCCH on the common E-DCH resource before sending the second uplink data; and a third sending module, configured to send the second uplink data when a preset time expires or within a certain time after the preset time expires after the DPCCH is restarted to be sent.

It should be understood that the network-side device 600 according to the embodiment of the present invention may correspond to a main body for executing the method in the embodiment of the present invention, and may also correspond to the network-side device 300 according to the embodiment of the present invention, and the above and other operations and/or functions of each module in the network-side device 600 are for implementing a corresponding flow of the method for data transmission described below, and are not described herein again for brevity.

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

The user equipment, the base station, the network side device and the communication system according to the embodiment of the present invention are described in detail above with reference to fig. 2 to 7, and a method of data transmission according to the embodiment of the present invention is described below with reference to fig. 8 to 12.

Fig. 8 shows a schematic flow chart of a method 700 of data transmission of one embodiment of the present invention. The method 700 is performed by a UE, comprising: s701, the UE sends first uplink data on a common enhanced dedicated channel (E-DCH) resource. S702, when the first uplink data transmission is completed and the common E-DCH resource is not released, the UE stops transmitting the DPCCH.

Therefore, the UE of the embodiment of the invention transmits the DPCCH and the uplink data on the common E-DCH resource allocated by the base station, and when the uplink data transmission is finished, the UE stops transmitting the DPCCH, so that the interference to other users in the cell can be reduced, and the system capacity can be improved.

The method 700 may be applied to other states relative to the CELL _ DCH state, for example, the other states may include a CELL _ FACH state, a CELL Paging Channel (CELL _ PCH) state, a UTRAN Registration Area Paging Channel (URA _ PCH) state, an idle state, and the like.

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

It should be understood that sending uplink Data in this context may be understood as UE sending uplink Control information to the base station through an E-DCH Dedicated Physical Control Channel (E-DPCCH), or sending uplink Data to the base station through an E-DCH Dedicated Physical Data Channel (E-DPDCH), or sending uplink feedback of downlink Data through a HS-DSCH Dedicated Physical Control (uplink) Channel (HS-DSCH) for HS-DSCH, HS-DPCCH. Wherein, the E-DCH is an Enhanced Dedicated Transport Channel (Enhanced Dedicated Transport Channel), and the HS-DSCH is a High-Speed Downlink Shared Channel (High-Speed Downlink Shared Channel).

Specifically, the ending of uplink data transmission herein means that the UE does not perform any data transmission to the base station side, where the data transmission may include that no data needs to be transmitted or retransmitted in the HARQ buffer of the UE, and the uplink feedback that the UE does not need to transmit to the base station on the HS-DPCCH may also be included. Correspondingly, the first uplink data transmission completion comprises the following steps: the buffer of a Radio Link Control (RLC) layer and/or a Media Access Control (MAC) layer of the UE is empty, and there is no uplink data to be transmitted or retransmitted in a Hybrid Automatic Repeat Request (HARQ) process, and the UE has no dedicated physical Control channel HS-DPCCH for a high-speed downlink shared channel HS-DSCH to be transmitted; or no uplink data needs to be transmitted or retransmitted in the HARQ process, and the UE does not have HS-DPCCH to send.

After acquiring the common E-DCH resource, the UE firstly transmits DPCCH on the common E-DCH resource. Then, the UE starts to transmit uplink data on the common E-DCH resource. And when the uplink data transmission is finished, the UE stops transmitting the DPCCH. Meanwhile, during the period that the UE keeps the common E-DCH resource (namely, 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 cannot receive the DPCCH transmitted by the UE, namely, the base station does not release the common E-DCH resource kept by the UE, namely, the base station still allows the UE to occupy the common E-DCH resource.

The UE may stop transmitting the DPCCH according to a predetermined rule, or may stop transmitting the DPCCH according to an instruction of the network side device, which is not limited in the embodiment of the present invention. Here, the UE and the base station stop transmitting in advance includes a criterion that the network side device (e.g., RNC) informs the UE and the base station to stop DPCCH transmission, respectively.

Therefore, the UE of the embodiment of the invention acquires the common E-DCH resource from the base station, transmits the DPCCH and the uplink data on the common E-DCH resource, and stops transmitting the DPCCH when the uplink data is transmitted, thereby reducing the interference to other users in the cell and improving the system capacity.

Optionally, as an embodiment, the method 700 further includes: and the UE receives indication information sent by the network side equipment, wherein the indication information is used for indicating that the UE stops sending the DPCCH when sending the uplink data in the period of keeping the common E-DCH resource. S702 when the first uplink data transmission is completed and the common E-DCH resource is not released, the UE stops transmitting the DPCCH, including: and the UE stops transmitting the DPCCH when the first uplink data is transmitted and common E-DCH resources are not released according to the indication information.

Specifically, the UE may receive, before acquiring the common E-DCH resource, indication information sent by the network side device, where the indication information is used to indicate that the UE stops sending the DPCCH when the UE finishes sending the first uplink data during the period of holding the common E-DCH resource (that is, when the common E-DCH resource is not released). Specifically, the indication information is used for indicating that the UE can stop DPCCH transmission when common E-DCH resources are reserved and no uplink data needs to be transmitted; or the UE is configured to instruct the UE to stop transmitting the DPCCH when the implicit resource release timer is started and no data is transmitted in a Hybrid Automatic Repeat Request (HARQ) process. And the UE stops sending the control information on the DPCCH when the condition is met according to the indication information sent by the network side equipment. 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 uplink data transmission is completed, the UE stops transmitting the control information on the DPCCH while continuing to maintain the common E-DCH resource.

It should be noted that, in this document, that the UE finishes sending uplink data and common E-DCH resource is not released includes a case that the UE does not satisfy implicit resource release or explicit resource release at this time. Namely: and when the UE does not reach the condition of resource release but does not have uplink data to be transmitted, the UE stops transmitting the DPCCH. Implicit resource release here refers to: and after the buffer memory of the UE is empty for a period of time, the UE sends a release instruction to the network side. Explicit resource release refers to: the base station or RNC instructs the UE to release the current common E-DCH resource.

The UE receives the indication information sent by the network side equipment, and the indication information sent by the network side equipment through system broadcasting can be received; the indication information may also be received, where the indication information is sent by a network side device through Radio Resource Control (RRC) dedicated signaling. The RRC dedicated signaling may be signaling for RRC connection setup (RRC connection setup), Cell Update confirm (Cell Update confirm), UTRAN Registration Area Update (UTRAN Registration Area Update, URA Update confirm), and the like, and the embodiments of the present invention are not limited thereto.

Preferably, as an embodiment, the receiving, by the UE, the indication information sent by the network side device includes: and the UE receives the indication information sent by the network side equipment through system broadcasting. In one particular example, the indication information may be carried in a system broadcast message. For example, the indication information may be carried by a bit of the system broadcast message, where "1" indicates that the indication information is carried and "0" indicates that the indication information is not carried. It should be understood that 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 whether it is necessary to stop transmitting the DPCCH when uplink data is not transmitted according to the indication information of the network side. The indication information may be sent by the network side device in a system broadcast message. The UE receives the indication information, and stops transmitting the DPCCH according to the indication information when the uplink data transmission is completed while the common E-DCH resource is reserved.

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 sending the control information on the DPCCH, reducing interference to other users in the cell, and improving system capacity.

Optionally, as an embodiment, after the UE stops transmitting the DPCCH S702, the method 700 further includes: the UE determines second uplink data to be sent; the UE restarts transmitting on the common E-DCH resource before transmitting the second uplink data; and the UE sends the second uplink data when the preset time after restarting sending the DPCCH expires or within a certain time after the preset time expires.

Specifically, when the UE needs to perform uplink data transmission again, the second uplink data to be transmitted is first determined (after the UE stops DPCCH transmission, the data waiting for transmission, which is delivered to the buffer of the UE again by the UE, may be different from another uplink data before the UE stops DPCCH transmission). Then, before sending the second uplink data, the UE restarts sending the DPCCH on the common E-DCH resource, namely, the UE sends control information such as a power control signal or a pilot signal on the DPCCH. And after the preset time for restarting transmitting the DPCCH, namely when the preset time after transmitting the control information on the DPCCH expires or within a certain time after the preset time expires, starting to transmit the second uplink data. The preset time may be determined by negotiation between the UE and the network side device, or may be a preset fixed value, for example, 2 time slots or 0 time slot, which is not limited in the embodiment of the present invention.

Alternatively, the preset time may be different according to the time when the UE stops DPCCH transmission. For example: if the UE stops DPCCH transmission for 20ms before transmitting the second uplink data, the UE selects a shorter preset time; if the DPCCH transmission is stopped for 100ms, the UE selects a longer preset time. The preset time value and the selection 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.

Optionally, as another embodiment, the method 700 further includes: the UE receives a discontinuous transmission period and a discontinuous transmission offset transmitted by the network side equipment; the UE calculates the time for restarting transmitting the DPCCH according to the discontinuous transmission period and the resource discontinuous transmission offset; and the UE restarts transmitting the DPCCH at the calculated time when the DPCCH transmission is restarted.

Specifically, the UE can obtain the time to restart transmitting the DPCCH when there is no uplink data transmission, as follows. When no uplink data is transmitted, the UE calculates a series of time points (i.e. a pattern transmitted by the DPCCH) at which the DPCCH needs to be transmitted by using the following formula (1):

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

wherein, DTX _ cycle and DTX _ offset are discontinuous transmission cycle and discontinuous transmission offset respectively sent to the UE by the network side, and MOD is a modulus operation. Through the above formula, a series of CFNs and S can be calculated, where CFN is a Connection Frame Number (Connection Frame Number) and S is a subframe Number in one Connection Frame. The series of CFNs and ss constitute a series of transmission instants, thus constituting a transmission pattern for the DPCCH.

Therefore, the UE of the embodiment of the invention acquires the common E-DCH resource from the base station, transmits the DPCCH and the uplink data on the common E-DCH resource, and stops transmitting the DPCCH when the uplink data is transmitted, thereby reducing the interference to other users and improving the system capacity.

The data transmission method according to the embodiment of the present invention is described in detail from the perspective of the UE in conjunction with fig. 8, and the data transmission method according to the embodiment of the present invention is described in detail from the perspective of the base station.

Fig. 9 shows a schematic flow chart of a method 800 of data transmission of one embodiment of the present invention. The method 800 is performed by a base station, comprising: s801, a base station allocates common E-DCH resources of a common enhanced dedicated channel to UE; s802, the base station receives the uplink data sent by the UE on the common E-DCH resource; and S803, when the UE is detected to finish sending the uplink data and the common E-DCH resource is not released, the base station stops sending the dedicated physical control channel DPCCH, and reserves the common E-DCH resource for the UE.

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

And the base station receives the uplink data sent by the UE on the common E-DCH resource. Since the UE may be discontinuous in transmitting uplink data during the time when the common E-DCH resource is reserved, the base station reserves the common E-DCH resource for the UE when the base station detects that the UE has finished transmitting the uplink data and stops transmitting the DPCCH when the common E-DCH resource is not released. That is, even if the base station does not receive the DPCCH transmitted by the UE, the base station does not release the common E-DCH resource held by the UE, i.e., the base station allows the UE to occupy the common E-DCH resource.

Therefore, after allocating the common E-DCH resource to the UE, the base station of the embodiment of the present invention receives the uplink data sent by the UE on the common E-DCH resource, and when stopping sending the DPCCH when detecting that the UE has finished sending the uplink data, the base station still reserves the common E-DCH resource for the UE, and does not affect the usage effect of the UE in the connected state while increasing the cell capacity.

Optionally, as an embodiment, the method 800 further includes: the base station receives indication information sent by the network side equipment, wherein the indication information is used for informing the base station that the UE stops sending DPCCH when sending uplink data in the period of keeping the common E-DCH resource; s803 when it is detected that the UE has finished sending the uplink data and the common E-DCH resource is not released, the base station stops sending the DPCCH, and reserves the common E-DCH resource for the UE, including: and the base station reserves the common E-DCH resource for the UE when stopping transmitting the DPCCH when detecting that the UE finishes transmitting the uplink data and the common E-DCH resource is not released according to the indication information. Specifically, the network side device may notify the base station of information that the UE stops transmitting the DPCCH after transmitting the uplink data while maintaining the common E-DCH resource by transmitting the indication information to the base station. In order to inform the base station UE not to make DPCCH transmission during the reserved common E-DCH resource. The base station can not do detection after receiving the information, or can not release the resources of the side when the control information can not be detected on the DPCCH.

Preferably, the receiving, by the base station, the indication information sent by the network side device includes: the base station receives the indication information sent by the network side equipment 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 in a frame protocol manner. For example, the indication information is carried in HS-DSCH Frame Type2 and transmitted. In a specific example, the indication information may be carried in one bit in the HS-DSCH Frame Type 2. For example, the indication information may be carried by using a bit of HS-DSCH Frame Type2, where "1" indicates that the indication information is carried and "0" indicates that the indication information is not carried. It should be understood that the above is only one specific implementation of the embodiments of the present invention, and is not intended to limit the present invention. Or, before 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 in a signaling manner, which is not limited in the embodiment of the present invention.

The data transmission method according to the embodiment of the present invention is described in detail below from the perspective of the network side device with reference to fig. 10. Fig. 10 shows a schematic flow chart of a method 900 of data transmission according to an embodiment of the invention. The method 900 includes: s901, a network side device sends first indication information to a user equipment UE, wherein the first indication information is used for indicating that the UE stops sending a dedicated physical control channel DPCCH when sending uplink data in the period of keeping a common E-DCH resource of a common enhanced dedicated channel; and S902, the network side device sends second indication information to the base station, wherein the second indication information is used for informing the base station to reserve the common E-DCH resource for the UE when stopping sending DPCCH when the UE finishes sending uplink data during the period that the common E-DCH resource is reserved by the UE.

The network side device may send the indication information to the UE and the base station, respectively, before the UE acquires the common E-DCH resource from the base station. And the network side equipment sends indication information to the UE to indicate the UE to stop sending the DPCCH when the UE finishes sending the uplink data in the period of keeping the common E-DCH resource. Optionally, the network side device sends the indication information to the UE, and may send the indication information to the UE through a system broadcast message.

And the network side equipment sends indication information to the base station to inform the base station UE of stopping sending the DPCCH when sending the uplink data in the period of keeping the common E-DCH resource. Optionally, the network side device may send, by way of signaling, the indication information to the base station before the UE obtains the common E-DCH resource allocated by the base station for the UE, so as to notify the base station that the UE may stop sending the DPCCH when sending the uplink data while the UE holds the common E-DCH resource. The network side device sends the indication information to the base station, which may be sent through a high speed downlink shared channel Frame HS-DSCH Frame Type2 after the UE obtains the common E-DCH resource allocated by the base station. That is, the network side device notifies the base station of information that DPCCH transmission is not performed when the UE finishes transmitting uplink data while maintaining the common E-DCH resource in a frame protocol manner. So as to inform the base station UE not to transmit DPCCH when finishing transmitting the uplink data during the period of keeping the common E-DCH resource. The base station can not do detection after receiving the information, or can not release the resources of the side when the control information can not be detected on the DPCCH.

Optionally, as an embodiment, the method 900 further includes: the network side equipment sends the discontinuous transmission period and the discontinuous transmission offset to the UE, so that the UE calculates the time for restarting sending the DPCCH according to the discontinuous transmission period and the discontinuous transmission offset. The detailed description is not repeated herein, but rather the detailed description is provided in the foregoing specification.

The following describes a data transmission method according to an embodiment of the present invention with a specific example.

Fig. 11 shows a schematic flow chart of a method 1000 of data transmission of one embodiment of the present invention. The method 1000 includes the following steps.

S1001, the network side equipment sends indication information to the UE through system broadcasting. The indication information is used for indicating the UE to stop transmitting the DPCCH when the UE finishes transmitting the uplink data during the period of keeping the common E-DCH resource.

S1002, the UE acquires common E-DCH resources from the base station.

S1003, the network side equipment sends a protocol Frame HS-DSCH Frame Type2 to the base station, and informs the base station of the following contents in HS-DSCH Frame Type 2: and when the UE finishes transmitting the uplink data in the period of keeping the common E-DCH resource, the UE stops transmitting the DPCCH.

S1004, the UE transmits the DPCCH on the common E-DCH resource.

S1005, the UE transmits uplink data on the common E-DCH resource.

S1006, when the UE finishes transmitting the uplink data, the UE stops transmitting the DPCCH.

S1007, when the base station detects that the UE has finished sending the uplink data, it stops sending DPCCH, and reserves common E-DCH resource for the UE.

S1008, when the UE needs to transmit uplink data on the common E-DCH resource again, the UE determines other uplink data to be transmitted.

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

S1010, after restarting transmitting the DPCCH for a preset time, the UE performs uplink data transmission again.

Therefore, the UE of the embodiment of the invention acquires the common E-DCH resource from the base station, transmits the DPCCH and the uplink data on the common E-DCH resource, and stops transmitting the DPCCH when the uplink data is transmitted, thereby reducing the interference to other users in the cell and improving the system capacity. And the network side equipment informs the base station UE to stop sending the DPCCH when the uplink data is sent out in the period of keeping the common E-DCH resource, so that the base station can not detect after receiving the notification, or can not release the resource of the side when the control information is not detected on the DPCCH.

It should be understood that, in various embodiments of the present invention, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

At time t1, the UE acquires the common E-DCH resource and releases the common E-DCH resource at time t2, namely the time of the UE's holding the common E-DCH resource is t2-t 1. The UE starts to transmit uplink data at time t3, and finishes transmitting the uplink data at time t 4. the interval t4-t3 is within the time t2-t1, that is, the UE does not transmit uplink data for a while during the period of keeping the common E-DCH resource (time t2-t 1). After the UE of the embodiment of the present invention finishes transmitting the uplink data at time t4, the UE stops transmitting the DPCCH.
