2 is a schematic flowchart of a first embodiment of a data transmission method according to the present invention. The execution entity of this embodiment is a base station, and the method in this embodiment includes:

S201: Receive a protocol frame sent by a radio network controller.

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: Send, in the radio frame indicated by the data transmission indication information, an HS-DSCH protocol data unit including a payload to the UE.

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.

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.

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.

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.

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.

3 is a schematic flowchart of a second embodiment of a data transmission method according to the present invention. The execution entity of this embodiment is a base station, and the method in this embodiment includes:

S301: Receive non-scheduling indication information sent by the RNC.

Specifically, before the RNC sends the protocol frame to the base station, the non-scheduling indication information is sent to the base station, where the non-scheduling indication information is used to indicate that the base station performs unscheduled transmission on the HS-DSCH protocol data unit that includes the payload corresponding to the non-scheduling indication information. The base station receives the foregoing non-scheduling indication information sent by the RNC.

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.

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.

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: Receive a protocol frame sent by the RNC, where the protocol frame carries the payload of the UE and the data transmission indication information.

Specifically, the base station receives the protocol frame sent by the RNC, where the protocol frame carries the payload of the UE and the data transmission indication information, where the data transmission indication information is used to indicate that the base station uses the unscheduled transmission mode according to the data transmission indication information to indicate the wireless The frame transmits an HS-DSCH protocol data unit containing the payload of the UE to the UE. 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. .

S303: Send, in the radio frame, the HS-DSCH protocol data unit that includes the payload corresponding to the non-scheduling indication information in the protocol frame to the UE.

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.

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.

In this embodiment, the base station receives the non-scheduling indication information sent by the RNC before receiving the protocol frame sent by the RNC. 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.

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: 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 protocol data unit.

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.

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.

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 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.

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.

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.

In this embodiment, the protocol frame is constructed by the RNC, and the protocol frame carries the payload and data transmission indication information of the UE, and sends a protocol frame to the base station, so that the base station sends the payload to the UE in the radio frame indicated by the data transmission indication information. The HS-DSCH protocol data unit realizes reducing the size of the header overhead and improving the reliability of data transmission.

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: 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.

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. .

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.

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.

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.

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.

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.

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: Send non-scheduling indication information to the base station.

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.

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.

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: Send a protocol frame to the base station.

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.

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.

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: 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.

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: 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.

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.

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.

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.

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: Receive non-scheduling indication information sent by the RNC.

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: Receive an HS-DSCH protocol data unit sent by the base station.

S803: Determine a connection frame number CFN corresponding to a new transmission of the HS-DSCH protocol data unit.

When the downlink uses HS-DSCH transmission, there are two ways, namely, a high-speed shared control channel.

(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.

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.

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: 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.

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.

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.

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.
