具体地 , 无线网络控制器（ Radio Network Controller , 以下简称： RNC ) 向基站发送协议帧，协议帧中携带用户设备 ( User Equipment, 以下简称： UE )的有效载荷和数据传输指示信息，本发明对数据传输指示信息的具体格式不做限定，数据传输指示信息用于指示基站根据该数据传输指示信息釆用非调度的传输方式在指示的无线帧向 UE 发送包含 UE 的有效载荷的 HS-DSCH协议数据单元。传输方式一般分为调度传输方式和非调度传输方式，调度方式即根据基站的调度策略确定 HS-DSCH协议数据单元的传输时间，例如，在连接帧号（Connection Frame Number, 以下简称： CFN ) =1时收到协议帧，根据基站的调度策略可能在 CFN=3时或者在 CFN=5时传输包含协议帧中 UE的有效载荷的 HS-DSCH协议数据单元，这样就存在调度时延，即 2个 CFN时间间隔或者 4个的 CFN时间间隔，釆用调度传输方式，基站收到 HS-DSCH协议数据单元的时延。非调度方式即基站在指定的时间传输包含协议帧中 UE的有效载荷的 HS-DSCH协议数据单元，因此，不存在调度时延。 Specifically, the radio network controller (Radio Network Controller, hereinafter referred to as RNC) sends a protocol frame to the base station, where the protocol frame carries the payload and data transmission indication information of the user equipment (User Equipment, hereinafter referred to as UE). The specific format of the data transmission indication information is not limited. The data transmission indication information is used to indicate that the base station sends the HS-DSCH protocol including the payload of the UE to the UE in the indicated radio frame according to the data transmission indication information and the unscheduled transmission mode. Data unit. The transmission mode is generally divided into a scheduling transmission mode and a non-scheduled transmission mode. The scheduling mode determines the transmission time of the HS-DSCH protocol data unit according to the scheduling policy of the base station, for example, a Connection Frame Number (hereinafter referred to as CFN). 1 o'clock Receiving the protocol frame, according to the scheduling policy of the base station, the HS-DSCH protocol data unit including the payload of the UE in the protocol frame may be transmitted when CFN=3 or when CFN=5, so there is a scheduling delay, that is, 2 CFNs. The time interval or four CFN time intervals, using the scheduled transmission mode, the base station receives the delay of the HS-DSCH protocol data unit. The non-scheduled mode means that the base station transmits the HS-DSCH protocol data unit containing the payload of the UE in the protocol frame at a specified time, and therefore, there is no scheduling delay.

S202: 在数据传输指示信息所指示的无线帧，向 UE发送包含有效载荷的 HS-DSCH协议数据单元。 S202: Send, in the radio frame indicated by the data transmission indication information, an HS-DSCH protocol data unit including a payload to the UE.

具体地， RNC向基站发送的协议帧中携带 UE的有效载荷和数据传输指示信息，数据传输指示信息中指示数据传输的无线帧，基站接收到 RNC发送的协议帧之后，将协议帧中的 UE的有效载荷封装成 HS-DSCH协议数据单元，在数据传输指示信息所指示的无线帧，向 UE发送 HS-DSCH协议数据单元，以使 UE在上述无线帧接收 HS-DSCH协议数据单元。 Specifically, the protocol frame sent by the RNC to the base station carries the payload and data transmission indication information of the UE, and the radio frame indicating the data transmission in the data transmission indication information, and after receiving the protocol frame sent by the RNC, the base station sends the UE in the protocol frame. The payload is encapsulated into an HS-DSCH protocol data unit, and the HS-DSCH protocol data unit is transmitted to the UE in the radio frame indicated by the data transmission indication information, so that the UE receives the HS-DSCH protocol data unit in the radio frame.

作为一种可行的实现方式，数据传输指示信息为 CFN, 即基站接收到的协议帧中携带 CFN,则在该 CFN向 UE发送包含 UE的有效载荷的 HS-DSCH 协议数据单元。相当于 CFN既指示了数据传输方式为非调度传输方式，又指示了基站在该 CFN向 UE发送包含 UE的有效载荷的 HS-DSCH协议数据单元。 As a possible implementation, the data transmission indication information is a CFN, that is, the protocol frame received by the base station carries the CFN, and the CFN sends the HS-DSCH protocol data unit including the payload of the UE to the UE. The CFN indicates that the data transmission mode is the unscheduled transmission mode, and indicates that the base station sends the HS-DSCH protocol data unit including the payload of the UE to the UE in the CFN.

作为另一种可行的实现方式，当***帧号（ System Frame Number, 以下简称： SFN )编号为 0〜4095, —个无线帧内包含 5个子帧，子帧编号为 0〜4 时，上述数据传输指示信息还可以为 SFN 和子帧号，比如传输指示信息为 SFN=2和子帧号为 0, 即指示基站在 SFN=2, 子帧号为 0的时刻调度 UE的有效载荷；当子帧编号为 0〜4096*5-1 , 上述数据传输指示信息还可以为子帧号，比如传输指示信息为子帧号 8, 则表示基站在子帧号为 8的时刻调度所述有效载荷。 SFN与子帧号所起的作用与 CFN相同，此处不再赘述。 As another feasible implementation manner, when the system frame number (hereinafter referred to as: SFN) is 0 to 4095, and the number of subframes is 0 to 4, and the subframe number is 0 to 4, the foregoing data is used. The transmission indication information may also be an SFN and a subframe number, for example, the transmission indication information is SFN=2 and the subframe number is 0, that is, the base station is instructed to schedule the UE payload at the time when the SFN=2 and the subframe number is 0; The data transmission indication information may be a subframe number. For example, if the transmission indication information is the subframe number 8, the base station schedules the payload at the time when the subframe number is 8. The role of the SFN and the subframe number is the same as that of the CFN, and will not be described here.

由于本实施例中， RNC向基站发送的协议帧中携带 UE的有效载荷和数据传输指示信息，数据传输指示信息用于指示基站根据该数据传输指示信息釆用非调度的传输方式在指示无线帧，向 UE发送包含 UE 的有效载荷的 HS-DSCH协议数据单元。由于基站釆用非调度的方式向 UE发送 HS-DSCH 协议数据单元，不会产生调度时延，因此，在 PDCP层可釆用不包含任何头开销的 PDPC-PDU格式，并且，由于釆用非调度的传输方式可在介质访问控制（ Media Access Control-d, 以下简称： MAC-d ) 层进行加密，所以，在无线链路控制（ Radio Link Control , 以下简称： RLC )层的 RLC-PDU可以釆用透传模式（ Transparent Mode , 以下简称： ΤΜ )进行传输，即在 RLC层也可以釆用没有头开销的 RLC-PDU格式，由于在 PDCP层或 RLC层均可釆用没有头开销的 PDU格式，因此，减小了头开销的大小。 In this embodiment, the protocol frame sent by the RNC to the base station carries the payload and data transmission indication information of the UE, and the data transmission indication information is used to indicate that the base station uses the unscheduled transmission mode to indicate the radio frame according to the data transmission indication information. And transmitting, to the UE, an HS-DSCH protocol data unit including a payload of the UE. Since the base station transmits the HS-DSCH to the UE in a non-scheduled manner The protocol data unit does not generate scheduling delay. Therefore, the PDCP-PDU format that does not contain any header overhead can be used in the PDCP layer, and the media access control can be used in the medium access control (using the unscheduled transmission method). d, hereinafter referred to as: MAC-d) The layer is encrypted. Therefore, the RLC-PDU in the Radio Link Control (RLC) layer can adopt the transparent mode (hereinafter referred to as: ΤΜ). For the transmission, the RLC-PDU format without head overhead can also be used in the RLC layer. Since the PDU format without header overhead can be used in both the PDCP layer and the RLC layer, the header overhead is reduced.

本实施例，通过接收 RNC发送的协议帧，协议帧中携带 UE的有效载荷和数据传输指示信息；在数据传输指示信息所指示的无线帧，向 UE发送包含有效载荷的 HS-DSCH协议数据单元，以使 UE在上述无线帧接收 HS-DSCH 协议数据单元，实现了减小头开销的大小，增大了覆盖范围，提高了数据传输的可靠性。 In this embodiment, the protocol frame sent by the RNC is received, and the protocol frame carries the payload and data transmission indication information of the UE. In the radio frame indicated by the data transmission indication information, the HS-DSCH protocol data unit including the payload is sent to the UE. In order to enable the UE to receive the HS-DSCH protocol data unit in the foregoing radio frame, the size of the header overhead is reduced, the coverage is increased, and the reliability of data transmission is improved.

The base station receives the foregoing non-scheduling indication information sent by the RNC.

可选地，非调度指示信息为 RNC根据 MAC-d流（ flow )标识、逻辑信道标识或 MAC队列配置的指示信息；即当基站收到上述 MAC-d flow标识、逻辑信道标识或 MAC 队列对应的有效载荷时，釆用非调度传输方式进行传输，一般选择时延要求比较高的业务数据对应地 MAC-d flow标识、逻辑信道标识或 MAC队列配置非调度指示信息，例如语音业务。 Optionally, the non-scheduling indication information is indication information that is configured by the RNC according to the MAC-d flow (flow) identifier, the logical channel identifier, or the MAC queue; that is, when the base station receives the MAC-d flow identifier, the logical channel identifier, or the MAC queue corresponding to the MAC address. For the payload, the non-scheduled transmission mode is used for transmission. Generally, the MAC-d flow identifier, the logical channel identifier, or the MAC queue configuration non-scheduled indication information, such as voice service, corresponding to the service data with higher delay is required.

可选地，非调度指示信息为无线链路建立请求消息或者无线链路重配置消息或无线链路增加请求消息，即 RNC在无线链路建立请求消息或者无线链路重配置消息或者无线链路增加请求消息中携带非调度指示信息发送给基站， RNC也可将非调度指示信息单独发送给基站。 Optionally, the non-scheduling indication information is a radio link setup request message or a radio link reconfiguration message or a radio link add request message, that is, the RNC is in a radio link setup request message or a radio link reconfiguration message or a radio link. The non-scheduled indication information is sent to the base station, and the RNC may separately send the non-scheduling indication information to the base station.

可选地，非调度指示信息还可以通过 TM RLC 承载在高速分组接入层 HSPA上表示。即如果 TM RLC承载在 HSPA上，则相当于指示基站釆用非调度传输。 Optionally, the non-scheduling indication information may also be represented by the TM RLC bearer on the high speed packet access layer HSPA. That is, if the TM RLC is carried on the HSPA, it is equivalent to indicating that the base station is not using the non- Schedule transmission.

S302: 接收 RNC发送的协议帧，协议帧中携带 UE的有效载荷和数据传输指示信息。 S302: Receive a protocol frame sent by the RNC, where the protocol frame carries the payload of the UE and the data transmission indication information.

If the protocol frame sent by the RNC is received, the non-scheduling indication information sent by the RNC is also received. And the data transmission indication information is used to indicate that the base station sends, according to the data transmission indication information, an HS-DSCH protocol data unit that includes a payload corresponding to the non-scheduling indication information, and uses the unscheduled transmission mode to send the protocol frame in the indicated radio frame. .

具体地，非调度指示信息为根据 MAC-d flow标识、逻辑信道标识或 MAC 队列配置的指示信息，因此，基站在无线帧向 UE发送包含 MAC-d flow标识、逻辑信道标识或 MAC队列对应的有效载荷的 HS-DSCH协议数据单元。 Specifically, the non-scheduling indication information is indication information according to the MAC-d flow identifier, the logical channel identifier, or the MAC queue configuration. Therefore, the base station sends, in the radio frame, the MAC-d flow identifier, the logical channel identifier, or the MAC queue corresponding to the UE. The payload of the HS-DSCH protocol data unit.

由于基站釆用非调度的方式发送包含协议帧中与非调度指示信息对应有效载荷的 HS-DSCH协议数据单元，不会产生调度时延，因此，包含与非调度指示信息对应的有效载荷的 HS-DSCH协议数据单元，在 PDCP层可釆用不包含任何头开销的 PDPC-PDU格式，并且，由于釆用非调度的传输方式可在 MAC-d层进行加密，所以 , 在 RLC层的 RLC-PDU可以釆用 TM进行传输，即在 RLC层也可以釆用没有头开销的 RLC-PDU格式。由于在 PDCP层或 RLC层均可釆用没有头开销的 PDU格式，因此，减小了头开销的大小。 Since the base station transmits the HS-DSCH protocol data unit including the payload corresponding to the non-scheduling indication information in the protocol frame in a non-scheduled manner, no scheduling delay occurs, and therefore, the HS including the payload corresponding to the non-scheduling indication information -DSCH protocol data unit, PDPC-PDU format without any header overhead can be used in the PDCP layer, and since the non-scheduled transmission mode can be used for encryption at the MAC-d layer, RLC- at the RLC layer The PDU can be transmitted using the TM, that is, the RLC-PDU format without header overhead can also be used at the RLC layer. Since the PDU format without header overhead can be used in either the PDCP layer or the RLC layer, the overhead overhead is reduced.

The HS-DSCH protocol data unit containing the payload corresponding to the non-scheduled indication information in the protocol frame is transmitted to the UE in the indicated radio frame. Implementing a non-scheduled transmission for the received HS-DSCH protocol data unit including the payload corresponding to the non-scheduling indication information, and reducing the size of the HS-DSCH protocol data unit including the payload corresponding to the non-scheduling indication information, The reliability of the HS-DSCH protocol data unit transmission including the payload corresponding to the non-scheduling indication information is improved.

图 4为本发明数据传输方法实施例三的流程示意图，图 4的执行主体是 RNC, 本实施例的方法包括： 4 is a schematic flowchart of Embodiment 3 of a data transmission method according to the present invention, where the execution body of FIG. 4 is RNC, the method of this embodiment includes:

S401 : 构建协议帧，协议帧中携带 UE的有效载荷和数据传输指示信息；具体地， RNC构建协议帧，在 PDCP层釆用不包含任何头开销，只包含数据的 PDCP-PDU格式，在 RLC层的 RLC-PDU可以釆用 TM进行传输，即在 RLC层也可以釆用没有头开销的 RLC-PDU格式。在 MAC-d层釆用 Count-c 进行加密， Coimt-c由超帧号（Hyper Frame Number, 以下简称： HFN)和 CFN 组成， CFN的值为 RNC指示基站向 UE发送协议帧的 CFN值，即 UE在接收到 HS-DSCH协议数据单元之后，釆用相同的 CFN值对 HS-DSCH协议数据单元中的有效载荷进行解密，才能正确解析出上述有效载荷，协议帧中携带数据传输指示信息，数据传输指示信息用于指示基站根据该数据传输指示信息釆用非调度的传输方式在指示的无线帧向 UE 发送包含有效载荷的 S401: Build a protocol frame, where the protocol frame carries the payload and data transmission indication information of the UE; specifically, the RNC constructs a protocol frame, and uses a PDCP-PDU format that does not include any header overhead and only contains data in the PDCP layer, in the RLC The RLC-PDU of the layer can be transmitted by using the TM, that is, the RLC-PDU format without header overhead can also be used at the RLC layer. The MAC-d layer is encrypted by Count-c. The Coimt-c is composed of a Hyper Frame Number (HFN) and a CFN. The value of the CFN indicates that the base station sends the CFN value of the protocol frame to the UE. That is, after receiving the HS-DSCH protocol data unit, the UE decrypts the payload in the HS-DSCH protocol data unit by using the same CFN value, so that the payload can be correctly parsed, and the protocol frame carries the data transmission indication information. The data transmission indication information is used to indicate that the base station sends the payload including the payload to the UE in the indicated radio frame according to the data transmission indication information and the unscheduled transmission mode.

HS-DSCH协议数据单元。 HS-DSCH protocol data unit.

S402: 向基站发送协议帧，以使基站在数据传输指示信息所指示的无线帧向 UE发送包含有效载荷的 HS-DSCH协议数据单元。 S402: Send a protocol frame to the base station, so that the base station sends the HS-DSCH protocol data unit including the payload to the UE in the radio frame indicated by the data transmission indication information.

具体地， RNC向基站发送构建的协议帧，以使基站在数据传输指示信息所指示的无线帧向 UE发送包含有效载荷的 HS-DSCH协议数据单元。 Specifically, the RNC sends the constructed protocol frame to the base station, so that the base station sends the HS-DSCH protocol data unit including the payload to the UE in the radio frame indicated by the data transmission indication information.

作为一种可行的实现方式，数据传输指示信息为 CFN, 即 RNC向基站发送的协议帧中携带 CFN, 则指示基站在 CFN向 UE发送包含有效载荷的 As a possible implementation, the data transmission indication information is a CFN, that is, the protocol frame sent by the RNC to the base station carries the CFN, and the base station is instructed by the base station to send the payload including the payload to the UE.

HS-DSCH协议数据单元。相当于 CFN既指示了数据传输方式为非调度传输方式，又指示了基站在该 CFN向 UE发送包含有效载荷的 HS-DSCH协议数据单元。 HS-DSCH protocol data unit. The CFN indicates that the data transmission mode is a non-scheduled transmission mode, and indicates that the base station transmits the HS-DSCH protocol data unit including the payload to the UE in the CFN.

作为另一种可行的实现方式，当 SFN编号为 0〜4095,—个无线帧内包含 5个子帧，子帧编号为 0〜4时，上述数据传输指示信息还可以为 SFN和子帧号，比如传输指示信息为 SFN=2和子帧号为 0, 即指示基站在 SFN=2, 子帧号为 0的时刻调度 UE的有效载荷；当子帧编号为 0〜4096*5-1 , 上述数据传输指示信息还可以为子帧号，比如传输指示信息为子帧号 8, 则表示基站在子帧号为 8的时刻调度所述有效载荷， SFN与子帧号所起的作用与 CFN相同，此处不再赘述。 As another possible implementation manner, when the SFN number is 0 to 4095, the number of the radio frame includes 5 subframes, and the subframe number is 0 to 4, the data transmission indication information may also be an SFN and a subframe number, for example, The transmission indication information is SFN=2 and the subframe number is 0, that is, the base station is instructed to schedule the payload of the UE when the SFN=2 and the subframe number is 0; when the subframe number is 0 to 4096*5-1, the above data transmission The indication information may also be a subframe number. For example, if the transmission indication information is the subframe number 8, the base station schedules the payload at a time when the subframe number is 8. The SFN and the subframe number play the same role as the CFN. I won't go into details here.

由于本实施例中， RNC向基站发送的协议帧中携带 UE的有效载荷和数据传输指示信息，数据传输指示信息用于指示基站根据该数据传输指示信息釆用非调度的传输方式在指示的无线帧向 UE发送包含有效载荷的 HS-DSCH 协议数据单元。由于 RNC指示基站釆用非调度的方式在指示的无线帧向 UE 发送包含有效载荷的 HS-DSCH协议数据单元，因而不会产生调度时延，因此，在 PDCP层可釆用不包含任何头开销的 PDPC-PDU格式，并且，由于釆用非调度的传输方式可在 MAC-d层进行加密，所以，在 RLC层的 RLC-PDU 可以釆用 TM进行传输，即在 RLC层也可以釆用没有头开销的 RLC-PDU格式。由于在 PDCP层或 RLC层均可釆用没有头开销的 PDU格式，因此，减小了头开销的大小。 In this embodiment, the protocol frame sent by the RNC to the base station carries the payload and data transmission indication information of the UE, and the data transmission indication information is used to indicate that the base station transmits the indication information according to the data. The HS-DSCH protocol data unit containing the payload is transmitted to the UE in the indicated radio frame by using a non-scheduled transmission mode. Since the RNC instructs the base station to send the HS-DSCH protocol data unit containing the payload to the UE in the indicated radio frame in a non-scheduled manner, no scheduling delay is generated, and therefore, the PDCP layer can be used without any header overhead. The PDPC-PDU format, and because the non-scheduled transmission method can be used for encryption at the MAC-d layer, the RLC-PDU at the RLC layer can be transmitted using the TM, that is, the RLC layer can also be used without Header RLC-PDU format. Since the PDU format without header overhead can be used in either the PDCP layer or the RLC layer, the size of the header overhead is reduced.

The HS-DSCH protocol data unit realizes reducing the size of the header overhead and improving the reliability of data transmission.

图 5为本发明数据传输方法实施例四的流程示意图，图 5 的执行主体是 RNC, 本实施例的方法包括： FIG. 5 is a schematic flowchart of the fourth embodiment of the data transmission method of the present invention. The execution entity of FIG. 5 is an RNC, and the method in this embodiment includes:

S501 :向 UE发送非调度指示信息，以使 UE的 MAC-d层执行解密操作。具体地， UE 在接收到非调度指示信息后，根据非调度指示信息记录 HS-DSCH协议数据单元新传的 CFN, 以在 MAC-d层使用上述 CFN进行解密。 S501: Send non-scheduling indication information to the UE, so that the MAC-d layer of the UE performs a decryption operation. Specifically, after receiving the non-scheduling indication information, the UE records the newly transmitted CFN of the HS-DSCH protocol data unit according to the non-scheduling indication information, and uses the CFN to perform decryption at the MAC-d layer.

可选地，非调度指示信息为根据 MAC-d flow标识、逻辑信道标识或 MAC 队列配置的指示信息；即当 UE接收到上述 MAC-d flow标识、逻辑信道标识或 MAC 队列对应的有效载荷时，釆用去时延抖动机制向非接入层递交有效载荷，一般选择时延要求比较高的业务数据对应地 MAC-d flow标识、逻辑信道标识或 MAC队列配置非调度指示信息，例如语音业务。 Optionally, the non-scheduling indication information is indication information that is configured according to the MAC-d flow identifier, the logical channel identifier, or the MAC queue; that is, when the UE receives the MAC-d flow identifier, the logical channel identifier, or the payload corresponding to the MAC queue. And using the de-delay jitter mechanism to deliver the payload to the non-access stratum, generally selecting a MAC-d flow identifier, a logical channel identifier, or a MAC queue configuration non-scheduled indication information, such as a voice service, corresponding to a service data having a relatively high delay. .

作为一种可行的实现方式， UE的 RLC层或 PDCP层接收到非调度指示信息对应的有效载荷时，立即向非接入层递交有效载荷，具体地， UE接收到非调度指示信息后，则在 RLC层或 PDCP层接收到非调度指示信息对应的有效载荷时立即向非接入层递交有效载荷，以保证非接入层接收到有效载荷的基站侧限定必须在预设时间内传输完成一个 HS-DSCH协议数据单元，否则 , 丟弃该 HS-DSCH协议数据单元，以确保 UE接收到 HS-DSCH协议数据单元的连续性。 As a feasible implementation manner, when the RLC layer or the PDCP layer of the UE receives the payload corresponding to the non-scheduling indication information, the UE immediately delivers the payload to the non-access stratum, specifically, after receiving the non-scheduling indication information, the UE When the RLC layer or the PDCP layer receives the payload corresponding to the non-scheduling indication information, the payload is immediately delivered to the non-access stratum, so that the base station side limitation that the non-access stratum receives the payload must be completed within a preset time. HS-DSCH protocol data unit, otherwise, the HS-DSCH protocol data unit is discarded to ensure that the UE receives the HS-DSCH protocol data unit Continuity.

例如，语音业务对时延要求比较高，要求接入层每隔 20ms向非接入层递交一个数据包，因此，在基站侧限定在 20ms内传完成一个数据包， 20ms内传输不成功则丟弃该数据包，传输下一个数据包，以确保 UE每隔 20ms接收到一个数据包，并将数据包立即递交给非接入层，保证接入层每隔 20ms向非接入层递交一个数据包。 For example, the voice service requires a relatively high delay, and the access layer is required to submit a data packet to the non-access stratum every 20 ms. Therefore, the base station side is limited to complete one data packet within 20 ms, and the transmission is unsuccessful within 20 ms. Discard the data packet and transmit the next data packet to ensure that the UE receives a data packet every 20ms and immediately delivers the data packet to the non-access stratum, ensuring that the access layer submits a data to the non-access stratum every 20ms. package.

作为另一种可行的实现方式， UE的 RLC层或 PDCP层在接收到非调度指示信息对应的有效载荷时，最大拖延到达最大时延间隔后向非接入层递交有效载荷。 As another feasible implementation manner, when the RLC layer or the PDCP layer of the UE receives the payload corresponding to the non-scheduled indication information, the maximum delay reaches the maximum delay interval and delivers the payload to the non-access layer.

具体地，最大时延间隔为预定义的或可配置的。最大拖延时间与***的重传机制有关，假设针对语音业务， ***最大时延为 80ms, 即一个语音数据包的传输时延超过 80ms还未传输成功，则丟弃该语音数据包，传输下一语音数据包， UE可能在传输时延为 10ms、 20ms, 30ms, 40ms, 50ms等小于 80ms 的时间接收到语音数据包， UE 在接入层接收到语音数据包之后则拖延到 80ms再向非接入层递交该语音数据包，由于 UE接收到的数据包都是在拖延到达最大时延 80ms之后递交给非接入层，因此，保证了 UE每隔 20ms向非接入层递交一个语音数据包，保证了非接入层接收数据包的连续性。可选地，在***性能比较好的情况下，也可拖延到达小于最大拖延时间的时间递交数据包，例如，拖延到达 60ms之后递交接收到的语音数据包。 Specifically, the maximum delay interval is predefined or configurable. The maximum delay time is related to the retransmission mechanism of the system. Assume that the maximum delay of the system is 80ms for voice services. That is, if the transmission delay of a voice data packet exceeds 80ms and the transmission is successful, the voice data packet is discarded. For the voice data packet, the UE may receive the voice data packet when the transmission delay is 10ms, 20ms, 30ms, 40ms, 50ms, etc., less than 80ms, and the UE delays to 80ms after receiving the voice data packet at the access layer. The inbound layer submits the voice data packet. Since the data packets received by the UE are delivered to the non-access stratum 80 ms after the delay reaches the maximum delay, the UE is guaranteed to submit a voice data packet to the non-access stratum every 20 ms. Ensure that the non-access layer receives the continuity of the data packet. Optionally, in the case that the system performance is good, the data packet that arrives less than the maximum delay time may also be delayed, for example, delaying the delivery of the received voice data packet after 60 ms.

图 6为本发明数据传输方法实施例四去时延抖动机制示意图。如图 6所示，分别有四个数据包，传输序号（ Transmission Sequence Number,以下简称： TSN ) 分别为 TSN=1、 TSN=2、 TSN=3、 TSN=4。假设数据包的最大时延为 80ms, 每个 CFN=10ms, 则最大时延相当于 8个 CFN的时间间隔， TSN=1的数据包在 CFN=0传输，由于釆用重传机制， UE在 CFN=4正确接收， TSN=2的数据包在 CFN=2传输，由于釆用重传机制， UE在 CFN=7正确接收， TSN=3的数据包在 CFN=4传输， UE在 CFN=4正确接收， TSN=4的数据包在 CFN=6传输，由于釆用重传机制， UE在 CFN=12正确接收； UE在 CFN=4正确接收到 TSN=1的数据包时，其传输时延为 40ms, 则再等待 40ms向非接入层递交数据包，即在 CFN=8时向非接入层递交数据包，UE在 CFN=7正确接收到 TSN=2 的数据包时，其传输时延为 50ms, 则再等待 30ms向非接入层递交数据包，即在 CFN=10时向非接入层递交数据包，同理， UE在 CFN=4正确接收到 TSN=3 的数据包时，其传输时延为 0ms, 则再等待 80ms向非接入层递交数据包，即在 CFN=12时向非接入层递交数据包， UE在 CFN=12正确接收到 TSN=4的数据包时，其传输时延为 60ms, 则再等待 20ms向非接入层递交数据包，即在 CFN=14 时向非接入层递交数据包，即 UE在 CFN=8, CFN=10, CFN=12, CFN=14向非接入层递交数据包 ,从而保证 UE每隔 2个 CFN时间间隔 ,也就是每隔 20ms向非接入层递交数据包，保证了非接入层接收到数据包的连续性。 FIG. 6 is a schematic diagram of a four-delay jitter mechanism according to Embodiment 4 of the data transmission method of the present invention. As shown in FIG. 6, there are four data packets respectively, and the transmission sequence number (hereinafter referred to as TSN) is TSN=1, TSN=2, TSN=3, and TSN=4, respectively. Assume that the maximum delay of the data packet is 80ms, and each CFN=10ms, the maximum delay is equivalent to the time interval of 8 CFNs, and the data packet with TSN=1 is transmitted at CFN=0. Due to the retransmission mechanism, the UE is CFN=4 is correctly received, and the packet with TSN=2 is transmitted in CFN=2. Due to the retransmission mechanism, the UE receives correctly at CFN=7, the packet with TSN=3 is transmitted at CFN=4, and the UE at CFN=4. Correctly received, the data packet with TSN=4 is transmitted in CFN=6, because the UE uses the retransmission mechanism, the UE receives correctly at CFN=12; when the UE correctly receives the data packet with TSN=1 at CFN=4, its transmission delay If it is 40ms, then wait for 40ms to submit the data packet to the non-access stratum, that is, when the CFN=8, the data packet is delivered to the non-access stratum, and when the UE correctly receives the data packet of TSN=2 when CFN=7, the transmission time is After the delay is 50ms, wait for 30ms to submit the data packet to the non-access stratum, that is, When CFN=10, the data packet is delivered to the non-access stratum. Similarly, when the UE correctly receives the TSN=3 data packet with CFN=4, the transmission delay is 0ms, and then waits for 80ms to submit to the non-access stratum. The data packet, that is, when the CFN=12, the data packet is delivered to the non-access stratum, and when the UE correctly receives the data packet with TSN=4 when CFN=12, the transmission delay is 60ms, and then waits for 20ms to the non-access stratum. The data packet is delivered, that is, when the CFN=14, the data packet is delivered to the non-access stratum, that is, the UE submits the data packet to the non-access stratum at CFN=8, CFN=10, CFN=12, and CFN=14, thereby ensuring that the UE The packet is delivered to the non-access stratum at intervals of 2 CFN intervals, that is, every 20 ms, ensuring the continuity of the data packets received by the non-access stratum.

可选地，非调度指示信息包括无线链路建立请求消息或者无线链路重配置请求消息或者无线链路增加请求消息。即 RNC可通过在无线链路建立请求消息或者无线链路重配置消息或者无线链路增加请求消息中携带非调度指示信息发送给基站。 Optionally, the non-scheduled indication information includes a radio link setup request message or a radio link reconfiguration request message or a radio link increase request message. That is, the RNC may send the non-scheduled indication information to the base station in the radio link setup request message or the radio link reconfiguration message or the radio link increase request message.

S502: 向基站发送非调度指示信息。 S502: Send non-scheduling indication information to the base station.

具体地，向基站发送非调度指示信息，以使基站在接收到协议帧之后在数据传输指示信息所指示的无线帧向 UE发送包含协议帧中与非调度指示信息对应的有效载荷的 HS-DSCH协议数据单元。 Specifically, the non-scheduling indication information is sent to the base station, so that the base station sends the HS-DSCH including the payload corresponding to the non-scheduling indication information in the protocol frame to the UE in the radio frame indicated by the data transmission indication information after receiving the protocol frame. Protocol data unit.

可选地，非调度指示信息为根据 MAC-d flow标识、逻辑信道标识或 MAC 队列配置的指示信息。即当基站收到上述 MAC-d flow标识、逻辑信道标识或 MAC队列对应的有效载荷时，釆用非调度传输方式进行传输，一般选择时延要求比较高的业务数据对应地 MAC-d flow标识、逻辑信道标识或 MAC队列配置非调度指示信息，例如语音业务。 Optionally, the non-scheduling indication information is indication information according to the MAC-d flow identifier, the logical channel identifier, or the MAC queue configuration. That is, when the base station receives the MAC-d flow identifier, the logical channel identifier, or the payload corresponding to the MAC queue, the base station uses the unscheduled transmission mode to perform the transmission, and generally selects the MAC-d flow identifier corresponding to the service data with a relatively high delay. The logical channel identifier or the MAC queue configures non-scheduling indication information, such as voice service.

可选地，非调度指示信息为无线链路建立请求消息或者无线链路重配置消息或者无线链路增加请求消息。即 RNC在无线链路建立请求消息或者无线链路重配置消息或者无线链路增加请求消息中携带非调度指示信息发送给基站，基站通过接收无线链路建立请求消息或者无线链路重配置消息或者无线链路增加请求消息接收非调度指示信息。 RNC也可将非调度指示信息单独发送给基站。 Optionally, the non-scheduling indication information is a radio link setup request message or a radio link reconfiguration message or a radio link addition request message. That is, the RNC carries the non-scheduling indication information in the radio link setup request message or the radio link reconfiguration message or the radio link increase request message, and the base station sends the radio link setup request message or the radio link reconfiguration message or The radio link addition request message receives non-scheduling indication information. The RNC can also send non-scheduled indication information to the base station separately.

S503: 向基站发送协议帧。 S503: Send a protocol frame to the base station.

具体地， RNC向基站发送构建的协议帧，基站在接收到协议帧之后在数据传输指示信息所指示的无线帧向 UE发送包含协议帧中与非调度指示信息对应的有效载荷的 HS-DSCH协议数据单元。由于本实施例中， RNC向基站发送的协议帧中携带数据传输指示信息，数据传输指示信息用于指示基站根据该数据传输指示信息釆用非调度的传输方式在指示的无线帧向 UE发送协议帧。由于 RNC指示基站釆用非调度的方式在指示的无线帧向 UE发送协议帧，因而不会产生调度时延，因此，在 PDCP 层可釆用不包含任何头开销的 PDPC-PDU格式，并且，由于釆用非调度传输方式可在 MAC-d层进行加密，所以，在 RLC层的 RLC-PDU可以釆用 TM 进行传输，即在 RLC层也可以釆用没有头开销的 RLC-PDU格式，因此，减小了头开销的大小。 Specifically, the RNC sends the constructed protocol frame to the base station, and after receiving the protocol frame, the base station sends the HS-DSCH protocol including the payload corresponding to the non-scheduling indication information in the protocol frame to the UE in the radio frame indicated by the data transmission indication information. Data unit. In this embodiment, the protocol frame sent by the RNC to the base station carries the data transmission indication information, where the data transmission indication information is used to instruct the base station to send the protocol to the UE in the indicated radio frame according to the data transmission indication information and the unscheduled transmission mode. frame. Since the RNC instructs the base station to send the protocol frame to the UE in the indicated radio frame in a non-scheduled manner, the scheduling delay is not generated. Therefore, the PDCP layer can use the PDPC-PDU format without any header overhead, and Since the non-scheduled transmission mode can be used for encryption at the MAC-d layer, the RLC-PDU at the RLC layer can be transmitted by using the TM, that is, the RLC-PDU format without head overhead can also be used at the RLC layer, , reducing the size of the head overhead.

本实施例中，通过 RNC向 UE发送非调度指示信息，以使 UE的 RLC层或 PDCP层接收到非调度指示信息对应的有效载荷时，釆用去去时延抖动机制向非接入层递交有效载荷，保证了非接入层接收到数据的连续性。通过向基站发送非调度指示信息，以使基站在接收到协议帧之后在数据传输指示信息所指示的无线帧向 UE 发送包含与非调度指示信息对应的有效载荷的 HS-DSCH 协议数据单元，减小包含与非调度指示信息对应的有效载荷的 HS-DSCH协议数据单元的大小，提高了包含与非调度指示信息对应的有效载荷的 HS-DSCH协议数据单元传输的可靠性。 In this embodiment, when the non-scheduling indication information is sent to the UE by the RNC, so that the RLC layer or the PDCP layer of the UE receives the payload corresponding to the non-scheduling indication information, the delay jitter mechanism is used to deliver the non-access layer to the non-access layer. The payload guarantees the continuity of the data received by the non-access stratum. Sending the non-scheduling indication information to the base station, so that the base station sends the HS-DSCH protocol data unit including the payload corresponding to the non-scheduling indication information to the UE in the radio frame indicated by the data transmission indication information after receiving the protocol frame, minus The size of the HS-DSCH protocol data unit that contains the payload corresponding to the non-scheduling indication information is small, and the reliability of the HS-DSCH protocol data unit transmission including the payload corresponding to the non-scheduling indication information is improved.

图 Ί为本发明数据传输方法实施例五的流程示意图，如图 Ί所示，本实施例的执行主体是 UE, 本实施例的方法包括： Figure Ί is a schematic flowchart of the fifth embodiment of the data transmission method of the present invention. As shown in Figure ,, the execution subject of the embodiment is a UE, and the method in this embodiment includes:

S701 : 接收基站在数据传输指示信息所指示的无线帧发送的 HS-DSCH 协议数据单元。 S701: Receive an HS-DSCH protocol data unit that is sent by the base station in the radio frame indicated by the data transmission indication information.

可选地，基站在数据传输指示信息所指示的无线帧发送 HS-DSCH协议数据单元，相应地， UE在上述无线帧处接收上述 HS-DSCH协议数据单元。 Optionally, the base station sends the HS-DSCH protocol data unit in the radio frame indicated by the data transmission indication information, and accordingly, the UE receives the HS-DSCH protocol data unit at the radio frame.

S702:确定 HS-DSCH协议数据单元对应的 HS-DSCH协议数据单元新传的 CFN,将 HS-DSCH协议数据单元中的有效载荷和 CFN递交给 MAC-d层，以在 MAC-d层根据 CFN对有效载荷进行解密。 S702: Determine a CFN newly transmitted by the HS-DSCH protocol data unit corresponding to the HS-DSCH protocol data unit, and submit the payload and the CFN in the HS-DSCH protocol data unit to the MAC-d layer to be based on the CFN at the MAC-d layer. Decrypt the payload.

具体地，由于现在的网络***多釆用重传机制，因此， UE接收到的协议数据单元可能为第一次传递的新的协议数据单元，也可能为重传的协议数据单元，将第一次传递的新的协议数据单元称为协议数据单元新传。 RNC构建协议帧时釆用 CFN在 MAC-d层对协议帧进行了加密，因此，相应地，在 UE 接收到协议帧后，获取 HS-DSCH 协议数据单元新传所对应的 CFN , 将 HS-DSCH协议数据单元中的有效载荷和 CFN递交给 MAC-d层，然后釆用相同的 CFN在 MAC-d层进行解密，才能对有效载荷正确解密。 Specifically, since the current network system uses a retransmission mechanism, the protocol data unit received by the UE may be a new protocol data unit that is delivered for the first time, or may be a retransmitted protocol data unit, which will be the first The new protocol data unit passed in the second pass is called the protocol data unit new pass. When the RNC constructs the protocol frame, the CFN encrypts the protocol frame at the MAC-d layer. Therefore, after receiving the protocol frame, the UE acquires the CFN corresponding to the new transmission of the HS-DSCH protocol data unit. The payload and CFN in the HS-DSCH protocol data unit are handed over to the MAC-d layer, and then decrypted with the same CFN at the MAC-d layer to correctly decrypt the payload.

由于基站在数据传输指示信息所指示的无线帧发送 HS-DSCH协议数据单元，即釆用非调度的方式发送协议帧，因而不会产生调度时延，因此，在 PDCP层可釆用不包含任何头开销的 PDPC-PDU格式，并且，由于釆用非调度的传输方式可在 MAC-d层进行加密，所以，在 RLC层的 RLC-PDU可以釆用 TM进行传输，即在 RLC层也可以釆用没有头开销的 RLC-PDU格式，因此，减小了头开销的大小。 Since the base station transmits the HS-DSCH protocol data unit in the radio frame indicated by the data transmission indication information, that is, the protocol frame is sent in a non-scheduled manner, no scheduling delay occurs, and therefore, the PDCP layer can be used without any inclusion. The PDPC-PDU format of the overhead overhead, and because the non-scheduled transmission mode can be used for encryption at the MAC-d layer, the RLC-PDU at the RLC layer can be transmitted by using the TM, that is, the RLC layer can also be used. The RLC-PDU format without head overhead is used, thus reducing the size of the overhead overhead.

本实施例中，通过 UE接收基站发送的 HS-DSCH协议数据单元，获取 HS-DSCH协议数据单元新传所对应的 CFN,将 HS-DSCH协议数据单元中的有效载荷和 CFN递交给 MAC-d层，以在 MAC-d层根据 CFN对有效载荷进行解密，实现了减小头开销的大小，提高了数据传输的可靠性。 In this embodiment, the UE receives the HS-DSCH protocol data unit sent by the base station, acquires the CFN corresponding to the new transmission of the HS-DSCH protocol data unit, and delivers the payload and the CFN in the HS-DSCH protocol data unit to the MAC-d. The layer is used to decrypt the payload according to the CFN at the MAC-d layer, thereby reducing the size of the header overhead and improving the reliability of data transmission.

图 8是本发明数据传输方法实施例六的流程示意图，如图 8所示，本实施例的执行主体是 UE, 本实施例的方法包括： FIG. 8 is a schematic flowchart of Embodiment 6 of the data transmission method of the present invention. As shown in FIG. 8, the execution entity of this embodiment is a UE, and the method in this embodiment includes:

S801 : 接收 RNC发送的非调度指示信息。 S801: Receive non-scheduling indication information sent by the RNC.

可选地，非调度指示信息可以为一独立的指示信息，也可以通过 TM RLC 承载在 HSPA上作为非调度指示信息。 Optionally, the non-scheduling indication information may be an independent indication information, or may be carried by the TM RLC on the HSPA as non-scheduling indication information.

S802: 接收基站发送的 HS-DSCH协议数据单元。 S802: Receive an HS-DSCH protocol data unit sent by the base station.

S803：确定 HS-DSCH协议数据单元新传所对应的连接帧号 CFN。 S803: Determine a connection frame number CFN corresponding to a new transmission of the HS-DSCH protocol data unit.

当下行釆用 HS-DSCH传输时，包括两种方式，分别为高速共享控制信道 When the downlink uses HS-DSCH transmission, there are two ways, namely, a high-speed shared control channel.

( High Speed Shared Control Channel, 以下简称： HS-SCCH )伴随方式和 HS-SCCH非伴随方式，其中， HS-SCCH伴随方式是指 HS-SCCH用来发送物理层控制信息，高速物理下行共享信道 ( High Speed Physical Downlink Shared Channel, 以下简称： HS-PDSCH )用来传输数据； HS-SCCH中的新传指示域 ( New data indicator )用于指示伴随的 HS-PDSCH数据是新传数据还是重传数据， UE需要记录接收到包含新传指示域的 HS-SCCH时的 CFN。 HS-SCCH非伴随方式下，新传数据不发送 HS-SCCH, 只发送 HS-PDSCH, 重传数据才会发送 HS-SCCH和 HS-PDSCH,其中 HS-SCCH中的指向前一传输指示域（ Pointer to the previous transmission )用 S表示， 6+S表示这次传输巨离新传的子帧个数，即需要根据 S推断 HS-PDSCH该重传对应的新传数据发送时的 CFN。当釆用伴随方式时， UE 可根据 HS-SCCH 中的新传指示域，确定 HS-DSCH协议数据单元的新传对应的 CFN,将 HS-DSCH协议数据单元中的有效载荷和新传对应的 CFN传递给 MAC-d层，以使 MAC-d层根据 CFN对有效载荷正确解密。 (High Speed Shared Control Channel, hereinafter referred to as: HS-SCCH) accompanying mode and HS-SCCH non-adjoint mode, where HS-SCCH adjoint mode means that HS-SCCH is used to transmit physical layer control information, high-speed physical downlink shared channel ( The High Speed Physical Downlink Shared Channel, hereinafter referred to as: HS-PDSCH, is used to transmit data; the New Data Indicator in the HS-SCCH is used to indicate whether the accompanying HS-PDSCH data is new or retransmitted. The UE needs to record the CFN when receiving the HS-SCCH including the new transmission indication field. In the HS-SCCH non-adjoint mode, the newly transmitted data is not sent to the HS-SCCH, only the HS-PDSCH is transmitted, and the retransmission data is sent to the HS-SCCH and the HS-PDSCH, where the HS-SCCH points to the previous transmission indication field ( Pointer to the previous transmission ) is represented by S, and 6+S indicates the number of subframes in which the transmission is newly transmitted, that is, the CFN at the time of transmission of the new transmission data corresponding to the HS-PDSCH retransmission needs to be inferred from S. When the adjoint mode is used, the UE may determine, according to the new transmission indication field in the HS-SCCH, the CFN corresponding to the new transmission of the HS-DSCH protocol data unit, and the payload corresponding to the new transmission in the HS-DSCH protocol data unit. The CFN is passed to the MAC-d layer so that the MAC-d layer correctly decrypts the payload according to the CFN.

当釆用非伴随方式时，分为两种情况，第一种情况，新传 HS-DSCH协议数据单元解析成功，确定正确接收 HS-DSCH协议数据单元的 CFN, 将上述 CFN作为 HS-DSCH协议数据单元对应的 HS-DSCH协议数据单元新传的 CFN,将 HS-DSCH协议数据单元中的有效载荷和 HS-DSCH协议数据单元对应的 HS-DSCH协议数据单元新传的 CFN传递给 MAC-d层，以使 MAC-d层根据 CFN对有效载荷正确解密。 When the non-adjoint mode is used, it is divided into two cases. In the first case, the newly transmitted HS-DSCH protocol data unit is successfully parsed, and the CFN that correctly receives the HS-DSCH protocol data unit is determined, and the CFN is used as the HS-DSCH protocol. The newly transmitted CFN of the HS-DSCH protocol data unit corresponding to the data unit transmits the payload in the HS-DSCH protocol data unit and the newly transmitted CFN of the HS-DSCH protocol data unit corresponding to the HS-DSCH protocol data unit to the MAC-d. Layer, so that the MAC-d layer correctly decrypts the payload according to the CFN.

第二种情况，当新传 HS-DSCH协议数据单元没有解析成功， UE接收到重传数据，则根据 HS-SCCH中的指向前一传输指示域，确定 HS-DSCH协议数据单元对应的 HS-DSCH协议数据单元新传的 CFN。具体地，根据 HS-SCCH 的物理层控制信息的指向前一传输指示域，推断出重传的是哪个新传 CFN的数据，确定 HS-DSCH协议数据单元对应的 HS-DSCH协议数据单元新传的 CFN,将 HS-DSCH协议数据单元中的有效载荷和 HS-DSCH协议数据单元对应的 HS-DSCH协议数据单元新传的 CFN传递给 MAC-d层，以使 MAC-d层根据 CFN对有效载荷正确解密。 In the second case, when the newly transmitted HS-DSCH protocol data unit is not successfully parsed, the UE receives the retransmission data, and determines the HS corresponding to the HS-DSCH protocol data unit according to the previous transmission indication field in the HS-SCCH. The newly transmitted CFN of the DSCH protocol data unit. Specifically, according to the previous transmission indication field of the physical layer control information of the HS-SCCH, it is inferred which retransmission CFN data is retransmitted, and the HS-DSCH protocol data unit corresponding to the HS-DSCH protocol data unit is determined to be newly transmitted. The CFN transmits the payload in the HS-DSCH protocol data unit and the newly transmitted CFN of the HS-DSCH protocol data unit corresponding to the HS-DSCH protocol data unit to the MAC-d layer, so that the MAC-d layer is valid according to the CFN pair. The payload is decrypted correctly.

S804: RLC层或 PDCP层在接收到非调度指示信息对应的有效载荷时，釆用去时延抖动机制，向非接入层递交有效载荷。 S804: When receiving the payload corresponding to the non-scheduling indication information, the RLC layer or the PDCP layer uses the de-delay jitter mechanism to deliver the payload to the non-access stratum.

可选地，非调度指示信息为 RNC根据 MAC-d flow标识、逻辑信道标识或 MAC队列配置的指示信息；即当 UE接收到上述 MAC-d flow标识、逻辑信道标识或 MAC 队列对应的有效载荷时，釆用去时延抖动机制向非接入层递交有效载荷，一般选择时延要求比较高的业务数据对应地 MAC-d flow标识、逻辑信道标识或 MAC队列配置非调度指示信息，例如语音业务。 Optionally, the non-scheduling indication information is indication information that is configured by the RNC according to the MAC-d flow identifier, the logical channel identifier, or the MAC queue; that is, when the UE receives the MAC-d flow identifier, the logical channel identifier, or the MAC queue corresponding to the payload. When the delay jitter mechanism is used to deliver the payload to the non-access stratum, the MAC-d flow identifier, the logical channel identifier, or the MAC queue configuration non-scheduled indication information, such as voice, is generally selected for the service data with higher delay. business.

作为一种可行的实现方式， UE的 RLC层或 PDCP层接收到非调度指示信息对应的有效载荷时，立即向非接入层递交有效载荷，具体地， UE接收到非调度指示信息后，则在 RLC层或 PDCP层接收到非调度指示信息对应的有效载荷时立即向非接入层递交有效载荷，以保证非接入层接收到有效载荷的基站侧限定必须在预设时间内传输完成一个 HS-DSCH协议数据单元，否则，丟弃该 HS-DSCH协议数据单元，以确保 UE接收到 HS-DSCH协议数据单元的连续性。 As a feasible implementation manner, when the RLC layer or the PDCP layer of the UE receives the payload corresponding to the non-scheduling indication information, the UE immediately delivers the payload to the non-access stratum, specifically, after receiving the non-scheduling indication information, the UE When the RLC layer or the PDCP layer receives the payload corresponding to the non-scheduling indication information, the payload is immediately delivered to the non-access stratum to ensure that the non-access stratum receives the payload. The base station side defines that one HS-DSCH protocol data unit must be transmitted within a preset time. Otherwise, the HS-DSCH protocol data unit is discarded to ensure that the UE receives the continuity of the HS-DSCH protocol data unit.

本实施例中，通过 UE接收 RNC发送的非调度传输指示信息，接收基站发送的 HS-DSCH协议数据单元，确定 HS-DSCH协议数据单元新传所对应的连接帧号 CFN, 将 HS-DSCH协议数据单元中的有效载荷和新传对应的 CFN 传递给 MAC-d层，以使 MAC-d层根据 CFN对有效载荷正确解密，实现了减小头开销的大小，提高了数据传输的可靠性。 In this embodiment, the UE receives the unscheduled transmission indication information sent by the RNC, receives the HS-DSCH protocol data unit sent by the base station, determines the connection frame number CFN corresponding to the new transmission of the HS-DSCH protocol data unit, and uses the HS-DSCH protocol. The payload in the data unit and the CFN corresponding to the new transmission are passed to the MAC-d layer, so that the MAC-d layer correctly decrypts the payload according to the CFN, thereby reducing the size of the header overhead and improving the reliability of data transmission.
