Description

Scheduling information transmission method and user terminal in enhanced dedicated channel

This application claims the priority of the Chinese patent application filed on May 26, 2006, the Chinese Patent Office, the application number is 200610082394.5, and the invention name is "enhanced dedicated channel scheduling information transmission method and user terminal". The citations are incorporated herein by reference.

Technical field

The present invention relates to the field of mobile communications, and in particular to an Enhanced Dedicated Channel ("E-DCH") technology.

Background technique

In the third generation mobile communication (The Third Generation, "3G") technology, the bearers of uplink and downlink services are based on dedicated channels. With the development of mobile communication technology, 3G technology is also evolving. High Speed Downlink Packet Access (HSDPA) and High Speed Uplink Packet Access (HSUPA) are important evolutions of 3G technology, packets in HSDPA and HSUPA. The scheduling and retransmission and the like are controlled by a base station node (Node B).

Among them, HSUPA is also called E-DCH, which is used as a high-speed uplink packet access technology.

2 milliseconds (ms) Transmission Time Interval (" ΤΤΓ") and shorter frame length for fast adaptive control, Hybrid Auto Repeat reQuest ("HARQ") and Node-based B's fast uplink scheduling technology improves the uplink frequency efficiency, and also has obvious advantages such as fast uplink transmission rate and small transmission delay, thus providing applications for packet data services such as real-time game services, file uploading, and broadband multimedia services. More efficient support. HARQ technology combines forward error correction code and retransmission for fast retransmission of E-DCH physical layer, and improves physical layer decoding through soft combining between initial transmission and retransmission. Performance.

For user equipment (User Equipment, referred to as "UE") (also commonly referred to as user terminal) for efficient transmission of uplink data, E-DCH newly adds two uplink physical channels and three downlink physical channels, which are respectively used for An E-DCH Dedicated Physical Data Channel (E-DCH Dedicated Physical Data Channel, referred to as "E-DPDCH") for carrying user data, for transmitting uplink data accompanying signaling for E-DPDCH demodulation The E-DCH Dedicated Physical Control Channel (E-DPCCH) is used to control the uplink transmission of the UE. The E-DCH Absolute Grant Channel (E-DCH Absolute Grant Channel) and the E-DCH Relative Grant Channel (E-RGCH), and the E-DCH Relative Grant Channel (E-RGCH) An E-DCH HARQ Indicator Channel (E-HCH), which is an acknowledgment/non-acknowledgement information (ACK/NACK) that carries the correct uplink data transmission.

The medium access control ("MAC") protocol layer of the E-DCH includes two MAC sublayers, MAC-e and MAC-es. The MAC-e entity on the UMTS Terrestrial Radio Access Network (UTRAN) side is in the Node B, and the MAC-es entity is in the Serving Radio Network Controller (Serving Radio Network Controller, In the abbreviation "SRNC", the MAC-e entity and the MAC-es entity on the UE side are in the same functional unit.

The payload portion of the MAC-e protocol data unit ("PDU") in the MAC-e entity includes a plurality of multiplexed MAC-es PDUs, optionally for uplink fast packet scheduling. The 18-bit Scheduling Information ("SI"), and the possible padding field used to make the length of the MAC-e PDU equal to the specified E-DCH transport block length.

The uplink fast packet scheduling of the E-DCH is implemented based on the Node B controlled Serving Grant ("SG") parameter. In order to simplify the control of the E-DCH uplink fast packet scheduling, one UE maintains one SG parameter, and the uplink packet transmission of all HARQ processes of the UE is controlled by the single SG parameter. The SG parameters maintained by the UE are controlled by an Absolute Grant ("AG") command carried in the E-AGCH and a Relative Grant ("RG") command carried in the E-RGCH.

The uplink fast packet scheduling of the E-DCH supports an independent scheduling mode based on a single UE and a group scheduling mode based on a UE group. In the independent scheduling mode based on a single UE, in the 2ms TTI mode, the Node B may not allow the UE to send schedulable data transmissions by configuring certain HARQ processes; the Node B may also allow the UE to be in an inactive state through the AG command. Or all HARQ processes send schedulable data transmissions; or the Node B stops some or all of the HARQ processes of the UE by the AG command to send schedulable data transmissions.

SI transmission has a very high priority, even if the current service authorization SG parameter is "Zero- Grant" (Zero authorization),,, or for the HARQ process in the inactive state, or for the HARQ process that is not allowed to send the schedulable data transmission, the SI is allowed to be transmitted, that is, all HARQ processes are allowed to transmit the SI report.

The SI is the measurement information that the E-DCH relies on for the Node B-based uplink fast packet scheduling, except that the UE reports the SI report based on the periodic trigger and the event-based trigger, when the number of free bits of the MAC-e PDU is equal to or greater than 18 bits. It will also be reported to SI. Among them, SI based on cycle trigger and event trigger based is called triggered SI (Triggered SI ).

SI is always transmitted on the E-DPDCH. There are two transmission modes: one is transmitted by the MAC-e PDU separately, that is, the entire MAC-e PDU is composed of 18 bits of SI; the other is that the SI is together with the data. Transmission, placing the SI behind the MAC-es PDUs that are multiplexed together in the MAC-e PDU.

The processing of the HARQ process in the E-DCH adopts a synchronous manner, that is, the initial transmission and retransmission of a HARQ process always occur at a fixed time. For the 2ms TTI mode, there are a total of 8 parallel HARQ processes; for the lOms TTI mode, there are a total of 4 parallel HARQ processes. Among them, each HARQ process has a corresponding maximum number of transmissions. In the case of SI transmission alone, the maximum number of retransmissions is fixed at 8 times; for the case where SI is transmitted together with data in the MAC-e PDU, the maximum number of retransmissions is determined by the E-DCH of the data portion of the MAC-e PDU. The HARQ configuration parameter of the MAC-d flow is determined by an information element ("Information", referred to as "IE") of the Radio Resource Control ("RRC"). "E-DCH MAC-d flow maximum number of Retransmission (E-DCH MAC-d flow maximum retransmission times) "Definition, its value range is 0 ~ 15.

Each UE has an E-DCH corresponding HARQ entity. At each TTI, the HARQ entity determines whether a buffer is generated according to whether the buffer of each HARQ process is empty, and determines that a new transmission is generated in the corresponding HARQ process. New data), or retransmission (that is, retransmit old data in the HARQ buffer). In the prior art, the HARQ processing process on the UE side is as shown in FIG. 1.

In step 101, first, it is determined whether the HARQ process satisfies the following three conditions simultaneously: al. The transmission of the HARQ process includes only the triggered SI, but does not include high-level data; a2. The current number of transmissions (by the variable CUR ENT_TX- NB save) less than the maximum number of transmissions;

A3. The radio link set (RLS) containing the serving cell is not received. ACK.

If the three conditions al, a2, and a3 are satisfied at the same time, the process proceeds to step 102; if not, the process proceeds to step 103.

In step 102, the HARQ process will continue with the retransmission and proceeds to step 103.

In step 103, it is further determined whether one or more of the following three conditions are satisfied:

M. Receive an ACK containing the RLS of the serving cell;

B2. Receive any ACK of RLS, and the transmission of the HARQ process contains high-level data; b3. The current number of transmissions (CURRENT-TX-B) is equal to or greater than the maximum number of transmissions. If at least one of the three conditions is satisfied, then go to step 104; otherwise, the process ends. In step 104, the buffer of the HARQ process is cleared, and then proceeds to step 105.

In step 105, it is judged whether the transmission of the HARQ process (still referring to the HARQ process mentioned in step 101) is satisfied: the SI containing the trigger, and the ACK containing the RLS of the serving cell is not received. If yes, go to step 106; otherwise, end the process.

In step 106, the SI reporting function is notified that the HARQ process failed to successfully transmit the triggered SI to the RLS containing the serving cell.

The processing after notifying the SI reporting function of the SI transmission failure message by step 106 is as shown in FIG.

In step 201, it is further determined whether the SI triggered by the transmission failure of the HARQ process is not multiplexed with the higher layer data in the same MAC-e PDU, that is, whether the transmission is a separate transmission of the SI, and if so, If no further operations are performed, the process ends; otherwise, the process proceeds to step 202.

In step 202, since the transmission of the HARQ process is a case where the triggered SI and the high layer data are multiplexed and transmitted in the same MAC-e PDU, a new primary SI report is triggered and the triggered new SI is transmitted to the Node B. .

In carrying out the invention, the inventors have found that the above solution has the following problems: The transmission of SI in E-DCH wastes radio resources.

The main reason for this situation is that since the SI is transmitted on the E-DPDCH, it is affected by the retransmission of the HARQ process. As shown in Figure 3, the MAC-e of the old SI is included in a HARQ process. During the period in which the PDU has not been successfully received by the ode B for retransmission, a MAC-e PDU transmission including a new SI may occur on other HARQ processes. Furthermore, if the MAC-e PDU containing the new SI has been successfully transmitted before the MAC-e PDU containing the old SI is successfully received by the Node B, that is, the new SI is successfully received by the Node B, then in this case: In the case of separate SI transmission, the UE side will continue to retransmit the MAC-e PDU containing the old SI but not the upper layer data. When the successful transmission of the MAC-e PDU containing the old SI is completed, if the Node B uses the old SI information for E-DCH packet scheduling, it will inevitably seriously affect the performance of the E-DCH packet scheduling. Therefore, the Node B needs to be old and new. The SI performs processing to discard the old SI to perform E-DCH packet scheduling using the new SI. It can be seen that this old SI is no longer useful. The retransmission of the MAC-e PDU containing the old SI wastes radio resources and increases the complexity of processing the new and old SI by the Node B.

For the case where the MAC-e PDU contains both the triggered SI and the upper layer data, it is possible to trigger a new primary SI report and transmit through the SI reporting function, but since the RLS including the serving cell has successfully received the new SI in other HARQ processes Information, so a new SI report triggered and transmitted by the SI reporting function is also unnecessary and also wastes wireless resources.

Summary of the invention

The embodiment of the invention provides a method for transmitting scheduling information in an enhanced dedicated channel and a user terminal, which reduces waste of radio resources of the SI transmission in the HARQ process of the E-DCH.

An embodiment of the present invention provides a method for transmitting scheduling information in an enhanced dedicated channel, including: when a hybrid transmission retransmission request HARQ process on a user side includes scheduling information, a first transmission includes a radio link set of a serving cell When the RLS is successfully received, if the second transmission on the other HARQ process includes scheduling information but does not include the high layer data, and the first transmission time of the second transmission is earlier than the first transmission time of the first transmission, the termination is performed. The second transmission on the HARQ process.

The embodiment of the present invention further provides an enhanced scheduling method for scheduling information in a dedicated channel, including: when a third transmission including scheduling information on any HARQ process of the user side is successfully received by an RLS including a serving cell, if another HARQ process The fourth transmission includes the triggered scheduling information and the high layer data, and the first transmission of the fourth transmission is earlier than the first transmission; the under transmission time is prohibited because the fourth transmission is not included The RLS of the serving cell successfully receives and triggers a new scheduling information report. The embodiment of the present invention further provides a user terminal, including a HARQ function entity, where at least two HARQ processes exist in the HARQ function entity, and further includes: a first determining module, configured to determine whether the first and second conditions are met simultaneously The first condition is that the first transmission that includes scheduling information on any HARQ process has been successfully received by the RLS that includes the serving cell; the second condition is that the second transmission that is ongoing on the other HARQ process includes scheduling information but Not including high layer data, and the first transmission time of the second transmission is earlier than the first transmission time of the first transmission; the HARQ function entity is instructed to terminate the HARQ process when the first and second conditions are simultaneously satisfied The second transmission on.

The embodiment of the present invention further provides a user terminal, including a HARQ function entity, where the HARQ function entity has at least two HARQ processes and a scheduling information reporting function entity, and further includes: a second determining module, configured to determine whether Satisfying the third condition that the third transmission containing the scheduling information on any HARQ process has been successfully received by the RLS including the serving cell; the fourth condition being ongoing on other HARQ processes The fourth transmission includes triggered scheduling information and high layer data, and the first transmission time of the fourth transmission is earlier than the first transmission time of the third transmission; and is prohibited if the third and fourth conditions are simultaneously satisfied The scheduling information reporting function entity triggers a new scheduling information report because the fourth transmission is not successfully received by the RLS including the serving cell.

As can be seen from the technical solution of the foregoing embodiments of the present invention, in an embodiment of the present invention, when the PDU containing the SI in any HARQ process is successfully received by the RLS including the serving cell, the other HARQ processes are terminated for the initial transmission time. Separate transmission of early SI. After a successful SI transmission, the older SI can not benefit the NodeB even if the transmission is successful. Stopping these unnecessary transmissions in time can effectively reduce the waste of wireless resources. Because the NodeB receives less SI, especially the amount of judgment on whether the SI is outdated, the processing load of the Node B on the SI is reduced. By timely terminating the transmission of outdated SI, the performance impact on E-DCH packet scheduling due to outdated SI can be reduced.

In another embodiment of the present invention, when the PDU including the triggered SI and the higher layer data is not successfully received by the RLS including the serving cell, if the PDU containing the newer SI in the other HARQ process has been included in the serving cell If the RLS is successfully received, the new SI report will no longer be triggered. Since the newer SI has been sent successfully, there is no need to re-trigger new for the sending failure of the older SI. One obituary, thereby reducing unnecessary retransmissions, effectively reducing the waste of radio resources, and correspondingly reducing the processing load of the Node B on the SI.

detailed description

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

In the embodiment of the present invention, when the transmission including the new SI on the user side of any HARQ process is successfully received by the radio link set RLS including the monthly service cell, if the transmission on the other HARQ process includes the old SI but does not include the upper layer data, Then the retransmission of the old SI on the HARQ process is terminated.

When the transmission of the new SI on the user side of any HARQ process is successfully received by the RLS including the serving cell, if the transmission on the other HARQ process includes the old triggered SI and the upper layer data, then the old triggered SI is included. When the transmission of the high-level data is not successfully received by the RLS containing the serving cell, it is prohibited to trigger a new SI report because of the event.

The SI transmission method in the E-DCH according to the first embodiment of the present invention is as shown in FIG. 4. When the transmission on the user side HARQ process is first transmitted, the time of the first transmission is recorded, for example, as CFN (Connection)

Frame Number, connection frame number) and sub-frame number representation. Those skilled in the art will readily appreciate that the specific means of recording the first transmission time include, but is not limited to, the manner of the CFN and the subframe number.

In step 401, it is determined whether the HARQ process satisfies the following three conditions simultaneously:

Al. The transmission of the HARQ process only contains the triggered SI, but does not contain high-level data; a2. The current number of transmissions (stored by the variable CURRENT-TX-NB) is less than the maximum transmission Number of times

A3. The ACK containing the RLS of the serving cell was not received.

If the three conditions of a1, a2, and a3 are satisfied at the same time, that is, the transmission on the HARQ process includes only the triggered SI but does not include the high layer data, and the transmission needs to be retransmitted, the process proceeds to step 402; if not, Then, the process proceeds to step 404.

In step 402, it is determined whether the following conditions are met:

Cl. The new SI transmitted by any other HARQ process has been successfully received by the LS containing the serving cell.

If the condition is satisfied, then go to step 404; otherwise, go to step 403.

The new transmission of the SI transmitted by each HARQ process is judged according to the recorded first transmission time on the HARQ process indicated by the CFN and the subframe number.

Step 403 is similar to step 102: the HARQ process will be retransmitted, and will not be described again, and then proceeds to step 404.

In step 404, it is further determined whether one or more of the following four conditions are satisfied:

Bl. Receive an ACK containing the RLS of the serving cell;

B2. Receive any ACK of LS, and the transmission of the HARQ process contains high-level data; b3. The current number of transmissions (CURRENT-TX-B) is equal to or greater than the maximum number of transmissions; b4. The transmission only contains the triggered SI, not The high-level data is included, and the new SI transmitted by any other HARQ process has been successfully received by the RLS containing the serving cell (ie, condition cl).

If at least one of the four conditions is satisfied, then go to step 405; otherwise, the flow ends. Steps 405 through 407 are also similar to steps 104 through 106, respectively, and will not be further described herein.

In the above embodiment, when the PDU containing the SI in any HARQ process is successfully received by the RLS including the serving cell, the other HARQ process terminates the separate transmission of the SI earlier than the initial transmission time. After an SI transmission succeeds, the older SI can not have a beneficial effect on the Node B even if the transmission is successful. Therefore, stopping the unnecessary SI transmission in time can effectively reduce the waste of the wireless resources. In addition, since the Node B receives less SI, in particular, it reduces the workload of judging whether the SI is outdated, so the processing load of the Node B on the SI is reduced. By terminating the outdated SI in time (ie old The SI transmission method in the E-DCH according to the second embodiment of the present invention is as shown in FIG. 5. When the transmission data on the HARQ process in the user terminal (ie, the user side) is first transmitted, the time of the first transmission is also recorded, with the CFN and the subframe number. Said.

Step 501 is similar to step 101, and details are not described herein again.

In step 502, it is determined whether the new SI transmitted by any other HARQ process has been successfully received by the RLS including the serving cell, and if so, proceeds to step 503; otherwise, proceeds to step 504. Among them, the newness of the SI transmitted by each HARQ process is also judged based on the recorded CFN and the subframe number.

In step 503, the buffer of the HARQ process is cleared, and the process ends.

Steps 504 through 508 are similar to steps 102 through 106, respectively, and are not again referred to herein.

Comparing the second embodiment of the present invention shown in FIG. 5 with the first embodiment of the present invention shown in FIG. 4, the difference between the two is mainly: in the case of triggered SI transmission alone, when transmitted due to other HARQ processes. When the new SI has been successfully received by the RLS including the serving cell (ie, the UE receives the ACK including the RLS of the serving cell) and does not retransmit the old SI, the HARQ process flow shown in FIG. 4 will notify the SI reporting function of the HARQ. The process fails to successfully send the triggered old SI to the RLS containing the serving cell; and the HARQ process flow shown in Figure 5 will not notify the SI reporting function that the HARQ process fails to successfully send the triggered SI to the RLS containing the serving cell. . It can be seen that, whether it is the first embodiment shown in FIG. 4 or the second embodiment shown in FIG. 5, as long as the new SI transmitted on other HARQ processes has been successfully received by the RLS including the serving cell, the old SI is not Will be retransmitted, therefore, these two specific implementations to some extent to avoid the waste of wireless resources.

The SI transmission method in the E-DCH according to the third embodiment of the present invention is as shown in FIG. 6. In the user terminal, if the SI transmission triggered by the HARQ process fails, that is, the HARQ process fails to successfully send the triggered SI to the RLS including the serving cell, the following process is performed. Those skilled in the art can understand that the HARQ process occurring in the user terminal can also be referred to as the HARQ process on the user side.

Step 601 is similar to step 201 and will not be described here.

In step 602, when the SI and the high layer data triggered by the HARQ process transmission failure are included When performing retransmission, the MAC-e PDU determines whether the new SI of any other HARQ process has been successfully received by the RLS including the serving cell, and if so, prohibits triggering a new SI report due to the event, and ends the process; Otherwise, the process proceeds to step 603. Wherein, the old and new SI transmitted by each HARQ process are also judged according to the recorded CFN and the subframe number.

Since the newer SI has been successfully transmitted, there is no need to re-trigger the new SI report for the older SI transmission failure. Therefore, in this case, it is forbidden to trigger a new SI report, which can reduce unnecessary SI transmission and effectively reduce The waste of radio resources also reduces the processing load of the Node B on the SI.

Step 603 is similar to step 202, and is not repeated here. When the first embodiment, the second embodiment or the third embodiment is used alone, the transmission of the outdated SI can be reduced to a certain extent, thereby improving the utilization of the radio resources. Furthermore, the first and third embodiments, or the second and third embodiments, are more effective when used in combination, and are capable of better suppressing the transmission of outdated SI. In addition, from the perspective of the NodeB, since the received SI is small, the workload for judging whether the SI is outdated is reduced, and the processing load of the Node B on the SI is reduced.

A person skilled in the art may understand that all or part of the steps in implementing the above method may be completed by a program instructing related hardware, and the program may be stored in a computer readable storage medium, the storage Media, such as: ROM/RAM, disk, CD, etc.

The present invention also discloses a user terminal embodiment. Referring to FIG. 7, which is a schematic structural diagram of a first embodiment of a user terminal according to the present invention, the user terminal in this embodiment includes a HARQ function entity 71, and further includes a first determining module. 72. In the following, in conjunction with the working principle of the user terminal of this embodiment, the internal structure is further disclosed.

There are at least two HARQ processes in the HARQ functional entity 71.

The first determining module 72 is configured to determine whether the following conditions (the first condition and the second condition) are simultaneously satisfied:

First condition: the first transmission containing SI on any HARQ procedure has been included in the serving cell

RLS successfully received;

Second condition: the second transmission being performed on other HARQ processes only contains the triggered SI but does not contain the upper layer data; and the first transmission of the second transmission is earlier than the first transmission of the first transmission Between.

If the above conditions are met at the same time, the first judging module instructs the HARQ function entity to terminate the second transmission on the HARQ process.

Further, the first determining module 72 specifically includes a first condition determining sub-module 721, a second condition determining sub-module 722, and a first control sub-module 723. Specifically, the user terminal determines, by the first condition determining sub-module 721, whether the first transmission containing the scheduling information on any of the HARQ processes has been successfully received by the RLS including the serving cell; the second condition determining sub-module 722 determines whether there is another The second transmission being performed on the HARQ process includes scheduling information but does not include higher layer data, and the first transmission time of the second transmission is earlier than the first transmission time of the first transmission. The first condition judging sub-module 721 and the second condition judging sub-module 722 inform the first control sub-module 723 of the respective judgment results (which may be positive or negative). Of course, the two judging sub-modules may also only When the result of the determination is a positive result, it is notified to the first control sub-module 723 that it is not necessary to notify the first control sub-module 723 if it is determined to be a negative result.

Further, the first control sub-module 723 instructs the HARQ function entity 71 to terminate the second transmission on the HARQ process when the determination result of the first condition determination sub-module 721 and the determination result of the second condition determination sub-module 722 are both positive results. .

In addition, the user terminal may further include a timing module, configured to record the time of the first transmission when the transmission on the HARQ process is first transmitted, and notify the time, and the object to be notified includes at least the first determining module 72. Those skilled in the art can understand that the specific implementation of the timing module can be implemented in various ways, such as recording the connection frame number and the subframe number sent for the first time.

The present invention also discloses an embodiment of a user terminal. Referring to FIG. 8, which is a schematic structural diagram of a second embodiment of a user terminal according to the present invention, the user terminal in this embodiment also includes a HARQ functional entity 71, and further includes a The second judging module 82 and the SI reporting function entity 83. The internal structure of the user terminal is further disclosed below in conjunction with the working principle of the user terminal of the embodiment.

Similarly, there are at least two HARQ processes in the HARQ function entity 71 in this embodiment.

The SI reporting function entity 83 is configured to trigger a new scheduling information report when the scheduling information including the triggering of the HARQ process and the transmission of the higher layer data are not successfully received by the RLS including the serving cell.

The second determining module 82 is configured to determine whether the following conditions are met simultaneously (third condition and fourth item) Pieces):

The third condition: the third transmission including the SI on any HARQ process has been successfully received by the RLS including the serving cell;

The fourth condition: the fourth transmission being performed on the other HARQ process includes the triggered SI and the upper layer data, and the first transmission time of the fourth transmission is earlier than the first transmission time of the third transmission;

If the above two conditions are met at the same time, the second determining module 82 controls the SI reporting function entity 83, that is, the SI reporting function entity 83 is notified that the fourth transmission is not included in the notification received by the HARQ function entity 71. When the RLS of the cell successfully receives this event indication, a new SI report is triggered because of the event. That is, in the case where the third and fourth conditions are simultaneously satisfied, the second judging module 82 prohibits the SI reporting function entity 83 from triggering a new obituary because the fourth transmission is not successfully received by the RLS containing the serving cell.

Specifically, the second determining module 82 specifically includes a third condition determining sub-module 821, a fourth condition determining sub-module 822, and a second control sub-module 823. The user terminal determines, by the third condition judging sub-module 821, whether the third transmission containing the scheduling information on any of the HARQ processes has been successfully received by the RLS including the serving cell; and determining whether there are other HARQ processes by using the fourth condition judging sub-module 822 The fourth transmission in progress includes scheduling information but does not include higher layer data, and the first transmission time of the fourth transmission is earlier than the first transmission time of the third transmission. The third condition judging sub-module 821 and the fourth condition judging sub-module 822 inform the second control sub-module 823 of the respective judgment results (which may be positive or negative). Of course, the two judging sub-modules may also only When the result of the determination is a positive result, the second control sub-module 823 is notified that it is not necessary to notify the second control sub-module 823 if it is determined to be a negative result.

Further, when the determination result of the third condition determination sub-module 821 and the determination result of the fourth condition determination sub-module 822 are both positive results, the second control sub-module 823 prohibits the SI "function function entity 83 because the fourth transmission is not A new SI report is triggered by the successful reception of the RLS containing the serving cell.

In addition, the user terminal may further include a timing module, configured to record the time of the first transmission when the transmission on the HARQ process is sent for the first time, and notify the time, and the object to be notified includes at least the second determining module 82.

It can be seen from the two embodiments of the above user terminal that no matter which specific embodiment is adopted, The transmission of outdated SI can be reduced, so that the problem of waste of wireless resources is solved to some extent, and the utilization of wireless resources is improved. In addition, from the perspective of the NodeB, since the received SI is small, the judgment workload for whether the SI is outdated is also reduced correspondingly, that is, the processing load of the Node B on the SI is reduced. In addition, the foregoing two user terminal embodiments can also be used in combination to achieve better radio resource utilization effects. When the foregoing two embodiments are used in combination, the user terminal includes a HARQ function entity 71, a first determining module 72, a second determining module 82, and an SI reporting function entity 83.
