Detailed ways

The implementation of the present invention provides a scheduling information reporting method, device and system, which provides a solution for the dual-carrier scheduling information reporting method, and can schedule resources of user equipment on each carrier of the dual-carrier, improving the flexibility of resource scheduling sex.

The scheduling information reporting method, device, and system provided by the embodiments of the present invention will be described in detail in various embodiments below with reference to the accompanying drawings.

Referring to FIG. 1 , it is a schematic flowchart of an embodiment of a method for reporting scheduling information in the present invention.

The method of this embodiment includes:

Step 100, obtaining status information of the data cache of the user equipment;

Step 101, obtain the user equipment power headroom of the first carrier and the user equipment power headroom of the second carrier of the user equipment; it should be noted that the user equipment power headroom of the first carrier is the total power of the user equipment and the dual carrier The relationship value of the power of the dedicated physical control channel of the first carrier, the power headroom of the user equipment of the second carrier is the relationship value between the total power of the user equipment and the power of the dedicated physical control channel of the second carrier in the dual carrier;

Step 102, reporting the status information of the data cache and the user equipment power headroom of the first carrier and the user equipment power headroom of the second carrier;

Optionally, the status information of the data cache, the user equipment power headroom of the first carrier, and the user equipment power headroom of the second carrier are sent in a MAC PDU (Medium Access Control Protocol Date Unit, medium access control protocol data unit) to the physical layer, and then to the NodeB (Node Base, base station node).

An embodiment of the present invention provides a dual-carrier scheduling information reporting method, by obtaining the status information of the data cache of the user equipment, and obtaining the UPH information of the first carrier and the UPH information of the second carrier of the user equipment respectively, and sending them Reporting to the network side improves the flexibility of dual-carrier reporting scheduling information.

The scheduling information refers to status information and UPH information of the data cache of the user equipment. In the embodiment of the present invention, the scheduling information reported by each carrier may be the status information of the data cache of the user equipment and the UPH information of the carrier, or it may only report the UPH information of the carrier, or it may be the data cache of the user equipment status information and UPH information of the two carriers.

A complete scheduling information (that is, scheduling information in the case of a single carrier) consists of the following four parts:

User equipment power headroom UPH(5bit) E-DCH total buffer status TEBS(5bit) Highest priority logical channel buffer status HLBS (4bit) Highest priority logical channel identifier HLID (4bit)

Wherein, the calculation method of UPH is UPH=P _max,tx /PDPCCH, wherein P _max,tx =min{Maximum allowed UL TX Power, P _max }, and P _max is the normalized maximum output power of UE. P _DPCCH is the power of the DPCCH code.

The status information of the data cache of the user equipment includes:

TEBS (Total E-DCH Buffer Status, the total buffer status of E-DCH): TEBS determines the total available data volume of all logical channels requested by RRC (Radio Resource Control, radio resource control), and also indicates RLC ( Radio Link Control, the amount of data available for transmission/retransmission.

HLBS (Highest priority Logical channel Buffer Status, the highest priority logical channel buffer status), HLBS indicates that the highest priority logical channel occupies the buffer.

HLID (Highest priority Logical channel ID, highest priority logical channel ID): When there are multiple highest priority logical channels at the same time, the reporting buffer occupies the highest channel.

It should be noted that, when two carriers in the dual carrier are triggered to report scheduling information, on the carrier that is triggered to report the scheduling information, the status information of the data cache of the user equipment and the UPH information of the carrier are reported.

Since the UPH information is related to the transmit code power of the carrier's DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel), when dual carriers are used in the uplink, the interference suffered by the two carriers is different, so the used DPCCH transmit code power is different, and the reported UPH information is also different. In the MAC (Medium Access Control, Media Access Control) entity, for example: in the MAC-e/MAC-i entity, two carriers share a buffer, and the TEBS, HLBS and HLID reported by the two carriers represent the same Therefore, when reporting dual-carrier SI, TEBS, HLBS, and HLID can be reported only once, but UPH information needs to be reported separately, otherwise the network side cannot calculate the maximum transmission E-DPCH (E-DCH Dedicated Physical Channel, E-DCH dedicated physical channel) power.

The method for reporting the scheduling information of the dual-carrier provided by the embodiment of the present invention specifically includes: by reporting the state information of the data cache of the user equipment and the UPH information of the first carrier on the first carrier, the information of the data cache of the user equipment is reported. The status information and the UPH information of the second carrier are reported on the second carrier; or the status information of the data cache of the user equipment and the UPH information of the carrier are reported on one carrier in the dual carrier, and only the carrier is reported on the other carrier or report the status information of the data cache of the user equipment, the UPH information of the first carrier, and the UPH information of the second carrier on the first carrier or the second carrier.

Referring to FIG. 2 , it is a schematic flowchart of another embodiment of the method for reporting scheduling information in the present invention.

In this embodiment, it is mainly explained that when the first carrier and the second carrier in the dual carrier are triggered to report the scheduling information at the same time, the data cache information of the user equipment in the dual carrier scheduling information and the UPH information (UPH1) of the first carrier are placed in the first Report in the MAC PDU sent by the carrier; report the UPH information (UPH2) of the second carrier in the MAC PDU sent by the second carrier.

Specifically, when two carriers report SI at the same time, the content is defined as follows:

Step 200, report complete 18-bit SI information on the first carrier, the SI information includes: UPH (5 bits), TEBS (5 bits), HLBS (4 bits), HLID (4 bits) of the first carrier.

Step 201, change the SI information of another carrier to 5bit, and only report the UPH information of this carrier in this carrier; specifically, only report the UPH (5bit) information of this carrier on the second carrier, and the data cached by the user equipment Status information (TEBS, HLBS, HLID) is no longer reported on the second carrier.

Specifically, if there is data transmission on each carrier of the dual carrier at this time, a carrier is randomly selected to report the status information of the data cache and the UPH information of the carrier, and only the UPH information of the carrier is reported on the other carrier ; When there is data transmission on only one carrier of the dual carrier, select the carrier with data transmission to report its UPH information, and report the data buffer status information and its UPH information on the carrier without data transmission. Of course, when triggering at the same time, if there is no data to send on the two carriers, the data buffer status information and the respective UPH information are reported on the two carriers.

It should be noted that the reporting of dual-carrier scheduling information may also adopt a reporting manner of always reporting data buffer status information and its UPH information on both carriers.

In this embodiment, for the case of MAC-e/MAC-i PDU (Protocol Data Unit, protocol data unit) filling and reporting SI, each carrier of the dual carrier also separately reports data status cache information and respective UPH information. Specifically, if Datasize+Header<=TBsize-24 selected by E-TFCI, then add DDI (Data Description Indicator) [111111] in the MAC-eHeader part, and add user equipment data after the MAC-e PDU Buffer status information and UPH information; if Datasize+Header<=TBsize-18 selected by E-TFCI, add user equipment data buffer status information and UPH information after the MAC-e/MAC-i PDU.

The scheduling information reporting method provided by the embodiment of the present invention simultaneously triggers the two carriers of the dual carrier to report the scheduling information, and reports the status information of the data cache and the UPH information of the carrier on one carrier; only reports the other carrier on the other carrier The UPH information improves the reporting efficiency of the dual-carrier scheduling information, and according to the reported dual-carrier scheduling information, the resource of the user equipment can be scheduled on each carrier of the dual-carrier, improving the flexibility of resource scheduling.

Referring to FIG. 3 , it is a schematic flowchart of another embodiment of the method for reporting scheduling information in the present invention.

The difference between this embodiment and the embodiment shown in FIG. 2 is that the status information of the data cache of the user equipment and the UPH information of the two carriers are reported on one carrier, so that the network side only needs to receive the scheduling information from one carrier. After obtaining all the scheduling information of the two carriers, the network side can calculate the request rate of the carrier according to the UPH of each carrier, so that the corresponding RG and AG scheduling authorization processing can be performed on each carrier.

In step 300, 5 bits are added to a complete 18-bit SI information to identify UPH information of another carrier, that is, to extend the scheduling information reported on a carrier, and the format becomes:

UPH1(5bit) UPH2(5bit) TEBS(5bit) HLBS(4bit) HLID(4bit)

Where UPH1 represents the UPH of the carrier carrying the extended SI information, and UPH2 represents the UPH information of another carrier.

But if the SGs of the two carriers cannot support the transmission of service data (for the fixed PDU size mode, the SG cannot send an RLC PDU, and for the variable PDU size mode, the SG cannot support the data transmission with E-TFCI greater than 0), then due to The minimum E-TFCI corresponding to the sending data is 18bit. At this time, the extended SI information cannot be transmitted. Therefore, in this case, two 18bit SI information are reported at the same time. The format of the SI information is the same as the original (including the data cache status information and the UPH for that carrier.).

Optionally, for the case where two carriers report an extended SI information, the two carriers can only use a set of timers T_SIG and T_SING, namely:

In step 301, a group of timers T_SIG and T_SING are used to simultaneously trigger the reporting of SI information of dual carriers; it should be noted that the timing periods of the timers T_SIG and T_SING are configured by the network side.

For using a set of timers to simultaneously trigger two carriers for SI reporting, the specific description is as follows:

Case 1 (Case 1):

Carrier 1: SG = "Zero_Grant" or all processes are inactive

Carrier 2: SG = "Zero_Grant" or all processes are inactive

If the TEBS becomes a value greater than 0, the reporting of dual-carrier SI information is triggered.

The arrival of higher priority data in the transmission buffer triggers the dual carrier to report SI information.

Configure an SI information cycle trigger timer T_SING, and start the timer T_SING when both carrier 1 and carrier 2 satisfy SG="Zero_Grant" or all processes are in an inactive state. When the timer T_SING expires, the reporting of dual-carrier SI information is triggered. The timer T_SING is restarted after the reporting of the dual-carrier SI information is triggered. During the timing period, if the state of Case 2 (Case2) or Case 3 (Case3) is entered due to a carrier SG or process state change, stop the T_SING timer and start the timer T_SIG at the same time. The timer T_SING needs to be restarted when SI is triggered to report during the timing period.

Case 2 (Case 2):

Carrier 1: SG <> "Zero_Grant" and at least one process is active

Carrier 2: SG <> "Zero_Grant" and at least one process is active

If TEBS>0 and the SG of a certain carrier becomes too small to transmit a PDU of any MAC-d flow, or the current SG of both carriers is too small to transmit a PDU of any MAC-d flow, TEBS becomes a value greater than 0, triggering the reporting of dual-carrier SI information.

If the E-DCH serving cell of a certain carrier changes, and the new serving cell does not belong to the original serving E-DCH RLS, trigger reporting of dual-carrier SI information.

When at least one carrier satisfies SG<>"Zero_Grant" and at least one process is active, start the timer T_SIG. When the timer T_SIG expires, the reporting of the SI information of the dual carrier is triggered. After the reporting of the SI information of the dual carriers is triggered, the timer T_SIG is restarted. During the timing period, if the state of Case1 is entered due to the change of the state of the two carrier SGs or processes, trigger SI, stop the T_SIG timer, and restart the timer T_SING at the same time, if TEBS>0 at this time, trigger to report SI; 3 (Case3), T_SIG restarts. If the SI information is triggered to be reported during the timing period, the timer T_SIG is restarted.

Case 3 (Case 3):

Carrier 1: SG="Zero_Grant" or all processes are inactive

Carrier 2: SG <> "Zero_Grant" and at least one process is active

TEBS becomes greater than 0 if TEBS > 0 and the SG of carrier 2 becomes too small to transmit a PDU of any MAC-d flow or the current SG of carrier 2 is too small to transmit a PDU of any MAC-d flow value, triggering the reporting of dual-carrier SI information;

If the E-DCH serving cell of carrier 2 changes, and the new serving cell does not belong to the original serving E-DCH RLS, trigger reporting of SI information of dual carriers.

When at least one carrier satisfies SG<>"Zero_Grant" and at least one process is active, start the timer T_SIG. When the timer T_SIG expires, the reporting of the SI information of the dual carrier is triggered. After the reporting of the SI information of the dual carriers is triggered, the timer T_SIG is restarted. During the timing period, if the carrier SG or process state changes and enters the Case1 state, stop the T_SIG timer and restart the timer T_SING at the same time, if TEBS>0 at this time, trigger the reporting of the SI information of the dual carrier; if it enters the Case2 state, the timing The T_SIG restarts. During the timing period, when the SI information of the dual carrier is triggered to be reported, the timer T_SIG is restarted.

It should be noted that in Case3, one carrier SG="Zero_Grant" or all processes are inactive, while another carrier SG<>"Zero_Grant" and at least one process is active, the timer T_SING can also be used .

Of course, the event triggering unit 5001 may also trigger dual carriers to report scheduling information at the same time, or report scheduling information separately, for example, when HARQ transmission fails, it also triggers reporting of SI information of dual carriers, specifically:

If the SI information is reported by the two carriers separately, wait for the periodic trigger of the timer, and report 18-bit SI information respectively.

Otherwise, two carriers report a 23-bit SI information.

Since the extended scheduling information is 23 bits, corresponding modifications should be made to the reporting of SI for MAC-e/MAC-i PDU filling: if Datasize+Header<=TBsize-29 selected by E-TFCI, then in MAC- Add DDI[111111] to the e Header part, add 23bit extended SI information after the MAC-e PDU; if Datasize+Header<=TBsize-23 selected by E-TFCI, add 23bit after the MAC-e/MAC-i PDU Extended SI information.

Regardless of whether it is event-triggered or periodic-triggered, if there is no data transmission on the two carriers, the buffer status information and the UPH of the corresponding carrier will be reported on the two carriers respectively; Report extended SI information (UPH1, UPH2, TEBS, HLBS, HLID); if data is sent on both carriers, then a carrier can be randomly selected to send extended SI information (UPH1, UPH2, TEBS, HLBS, HLID) , it is also possible to select a carrier to transmit extended SI information (UPH1, UPH2, TEBS, HLBS, HLID) according to the principle of minimum filling redundant bits when E-TFCI is selected.

It should be noted that, when adopting the reporting method of always independently reporting the buffer state information and the UPH information of the corresponding carrier on the two carriers, a group of timers provided in the embodiment of the present invention may also be used. When reporting scheduling information triggered by a timer period or an event, complete scheduling information (UPH1, TEBS, HLBS, HLID) is reported on the first carrier, and complete scheduling information (UPH2, TEBS, HLBS, HLID) is reported on the second carrier.

Optionally, in this embodiment, when triggering the reporting of dual-carrier scheduling information, UPH1, UPH2, TEBS, HLBS, and HLID may be reported on the first carrier, and UPH2, UPH1, TEBS, HLBS, and HLID may be reported on the second carrier at the same time. That is, the extended scheduling information is reported on both carriers at the same time

The scheduling information reporting method provided by the embodiment of the present invention reports extended scheduling information (UPH1, UPH2, TEBS, HLBS, HLID) on one carrier when dual carriers are triggered to report scheduling information, which improves the efficiency of dual carrier scheduling information reporting , and according to the reported dual-carrier scheduling information, the resource of the user equipment can be scheduled on each carrier of the dual-carrier, thereby improving the flexibility of resource scheduling.

Referring to FIG. 4 , it is a schematic structural diagram of an embodiment of a system for reporting scheduling information in the present invention.

The system provided in this embodiment includes:

The scheduling information reporting means 400 is configured to report the status information of the data cache of the user equipment and the user equipment power headroom of the first carrier of the user equipment and the user equipment power headroom of the second carrier to the scheduling authorization means 401; The user equipment power headroom of the first carrier is the relationship value between the total power of the user equipment and the power of the dedicated physical control channel of the first carrier in the dual carrier, and the user equipment power headroom of the second carrier is the user equipment The relationship value between the total power of the dual carrier and the power of the dedicated physical control channel of the second carrier in the dual carrier;

The authorization information receiving unit 401 is configured to receive the information related to the information sent by the scheduling authorization unit according to the status information of the data cache, the user equipment power headroom of the first carrier, and the user equipment power headroom of the second carrier. Scheduling grant information corresponding to the first carrier and the second carrier.

The device for reporting scheduling information in this embodiment may be a UE (User Equipment, user equipment) or other devices that need to report scheduling information during specific implementation. The device for receiving authorization information in this embodiment may also be the same physical entity as the device for reporting scheduling information during specific implementation, that is, it may be a UE or other devices that need to report scheduling information and receive scheduling authorization information.

During specific implementation, the scheduling authorization device may be a base station, or an eNB (evolved NodeBase), or other devices capable of authenticating and authorizing scheduling information.

The scheduling information reporting system provided by the embodiment of the present invention obtains the status information of the data cache of the user equipment, obtains the UPH information of the first carrier and the UPH information of the second carrier respectively, and reports them to the network side, thereby improving the dual-carrier reporting. Flexibility of scheduling information.

Referring to FIG. 5 , it is a schematic structural diagram of an embodiment of an apparatus for reporting scheduling information in the present invention.

When the dispatching information reporting device is specifically implemented, it includes:

A state information obtaining module 501, configured to obtain state information of the data cache to be sent by the user equipment;

The power headroom obtaining module 502 is configured to obtain the power headroom of the user equipment of the first carrier according to the relationship value between the total power of the user equipment and the power of the dedicated physical control channel of the first carrier in the dual carrier; according to the total power of the user equipment The relationship value with the power of the dedicated physical control channel of the second carrier in the dual carrier to obtain the power headroom of the user equipment of the second carrier;

The scheduling information reporting module 503 is configured to report the status information of the data cache, the power headroom of the user equipment of the first carrier, and the power headroom of the user equipment of the second carrier.

Specifically, the scheduling information reporting module 503 may report the status information of the data buffer of the user equipment and the UPH information of the first carrier on the first carrier, and report the status information of the data buffer of the user equipment and the UPH information of the second carrier on the first carrier. report on the second carrier;

Or the scheduling information reporting module 503 reports the status information of the data cache of the user equipment and the UPH information of the carrier on one carrier of the dual carrier, and reports only the UPH information of the carrier on the other carrier;

Alternatively, the scheduling information reporting module 502 reports the status information of the data cache of the user equipment, the UPH information of the first carrier, and the UPH information of the second carrier on the first carrier or the second carrier.

Optionally, the scheduling information reporting device also includes:

The triggering module 500 is configured to simultaneously trigger the first carrier and the second carrier to report scheduling information, or trigger the first carrier and the second carrier to report scheduling information respectively.

The scheduling information reporting device provided by the embodiment of the present invention, when two carriers of the dual carrier are respectively triggered to report the scheduling information, the status information of the data cache of the user equipment and the UPH information of the carrier are reported on the carrier that is triggered to report the scheduling information; When the two carriers of the dual carrier are triggered to report scheduling information at the same time, the status information of the user equipment's data cache and the UPH information of the carrier are reported on one carrier, and only the UPH information of the carrier is reported on the other carrier; or on one carrier The status information of the data cache of the user equipment and the UPH information of the two carriers are reported. The device for reporting scheduling information provides a complete solution for reporting dual-carrier scheduling information, improves the efficiency of reporting dual-carrier scheduling information, and according to the reported dual-carrier scheduling information, can be on each carrier of the dual-carrier. Resources are scheduled to improve the flexibility of resource scheduling.

Referring to FIG. 6 , it is a schematic structural diagram of another embodiment of an apparatus for reporting scheduling information in the present invention.

Firstly, it is explained that, in the embodiment of the present invention, the format of the scheduling information is as follows: it includes the status information of the data cache of the user equipment and the UPH information of each carrier.

User equipment power headroom UPH(5bit) E-DCH total buffer status TEBS(5bit) Highest priority logical channel buffer status HLBS (4bit) Highest priority logical channel identifier HLID (4bit)

Wherein, TEBS, HLBS, and HLLD collectively refer to the status information of the data cache of the user equipment.

The structures and functions of the triggering module 500, the state information obtaining module 501, and the power headroom obtaining module 502 of the scheduling information reporting device provided in this embodiment are the same as those in the previous embodiment, and will not be repeated here. This implementation will focus on the structure and functions of the scheduling information reporting module 503, which specifically includes:

The first reporting unit 5030 is configured to store the status information (TEBS, HLBS, HLID) of the data cache and the user equipment of the first carrier when the triggering module 500 simultaneously triggers the first carrier and the second carrier to report scheduling information The power headroom (UPH1) is reported on the first carrier in the dual carrier, and the user equipment power headroom (UPH2) of the second carrier is reported on the second carrier.

Specifically, if only one of the dual carriers has data transmission at this time, the carrier with no data transmission is preferentially selected, and the first reporting unit 5030 reports complete SI information on the carrier, and reports the SI information corresponding to the carrier on the other carrier. UPH information: when data is sent on both the first carrier and the second carrier, a carrier is randomly selected, and the first reporting unit 5030 reports complete SI information (TEBS, HLBS, HLID, UPH) on the randomly selected carrier, in Another carrier reports UPH information corresponding to another carrier.

The scheduling information reporting module 503 also includes:

The second reporting unit 5031, when the triggering module 500 triggers the first carrier and the second carrier to report the scheduling information at the same time, is used to store the status information of the data buffer and the user equipment power headroom of the first carrier and the user power headroom of the second carrier. The quantity value is reported on the first carrier or the second carrier.

Specifically, firstly, the scheduling information reported on a carrier is extended, and the format becomes:

UPH1(5bit) UPH2(5bit) TEBS(5bit) HLBS(4bit) HLID(4bit)

Where UPH1 represents the UPH of the carrier carrying the extended SI information, and UPH2 represents the UPH information of another carrier.

Regardless of whether the trigger module 500 is an event trigger or a periodic trigger, when there is only one carrier for data transmission, the second reporting unit 5031 reports extended SI information (UPH1, UPH2, TEBS, HLBS, HLID) on the carrier with data transmission; if There is data transmission on both carriers, then the second reporting unit 5031 can randomly select a carrier to send extended SI information (UPH1, UPH2, TEBS, HLBS, HLID), or fill the redundant bits with the minimum The principle to select a carrier to send extended SI information (UPH1, UPH2, TEBS, HLBS, HLID).

Optionally, in this embodiment, even when the trigger module 500 simultaneously triggers to report dual-carrier scheduling information, UPH1, UPH2, TEBS, HLBS, HLID may be reported on the first carrier, and UPH2, UPH1, TEBS may be reported on the second carrier , HLBS, HLID. That is, the extended scheduling information is reported on both carriers at the same time.

The scheduling information reporting module 503 also includes:

The third reporting unit 5032 is configured to report the status information of the data buffer and the user equipment power headroom of the first carrier on the first carrier when the triggering module 500 simultaneously triggers the first carrier and the second carrier to report scheduling information, The status information of the data cache and the user power headroom value of the second carrier are reported on the second carrier.

Specifically, when both carriers have no data to send, even if the two carriers are triggered to report scheduling information at the same time, both carriers report 18-bit scheduling information.

It should be noted that, when the dual carriers report the scheduling information, each carrier may always report separately. The third reporting unit 5032 reports 18-bit scheduling information for each carrier separately.

The scheduling information reporting module 503 also includes:

In the fourth reporting unit 5033, the triggering module 500 respectively triggers the first carrier and the second carrier to report the scheduling information, specifically, when the triggering module 500 triggers the first carrier to report the scheduling information, the status information of the data cache and the user of the first carrier The device power headroom is reported on the first carrier; when the second carrier is triggered to report the scheduling information, the status information of the data buffer and the user equipment power headroom of the second carrier are reported on the second carrier.

In this embodiment, when the SI is filled and reported for the MAC-e/MAC-i PDU, each carrier of the dual carrier also separately reports the complete SI information. Specifically, if Datasize+Header<=TB size-24 selected by E-TFCI, add DDI (Data Description Indicator) [111111] in the MAC-e Header part, and add an 18bit after the MAC-e PDU SI information; if Datasize+Header<=TBsize-18 selected by E-TFCI, add 18bit SI information after MAC-e/MAC-i PDU.

In the scheduling information reporting device provided by the embodiment of the present invention, when the two carriers of the dual carrier are respectively triggered to report the scheduling information, the carrier that is triggered to report the scheduling information reports the 18-bit scheduling information (TEBS, HLBS, HLID, UPH); simultaneously triggers the dual carrier Report the scheduling information on the two carriers, report the status information of the data buffer and the UPH information of the carrier on one carrier; report only the corresponding UPH information of the carrier on the other carrier; or report the status information of the data buffer and the UPH information of the two carriers All UPH information is reported in one carrier; or 18-bit scheduling information is reported on two carriers at the same time, which improves the efficiency of dual-carrier scheduling information reporting, and according to the reported dual-carrier scheduling information, can be used on each of the dual-carrier The resources of the user equipment are scheduled on the carrier to improve the flexibility of resource scheduling.

Referring to FIG. 7 , it is a schematic structural diagram of another embodiment of an apparatus for reporting scheduling information in the present invention.

The scheduling information reporting device in this embodiment is different from that in Figure 5 in that the triggering module 500 is specifically a timer cycle triggering unit 5000 and an event triggering unit 5001, and the functions and functions of other modules are the same, and this embodiment focuses on the triggering module The functions and functions of 500 include:

The timer period triggering unit 5000 includes at least one set of timers, which uses a set of timer periods to simultaneously trigger the first carrier and the second carrier to report scheduling information; or uses a set of timer periods to trigger the first carrier to report Scheduling information, using another set of timers to periodically trigger the second carrier to report scheduling information;

The event triggering unit 5001 is configured to event trigger the first carrier and the second carrier to report scheduling information respectively or simultaneously.

The timer period trigger unit 5000 includes at least one set of timers, specifically timers (T_SIG) and timers (T_SING). The timing periods of T_SIG and T_SING are configured by the network side to trigger the first carrier in the dual carrier The scheduling information is reported simultaneously with the second carrier.

Of course, two sets of timers can also be used to trigger each carrier separately for dual carriers. When two sets of timers trigger two carriers to report SI information at the same time, it can also be considered as simultaneous triggering of dual carriers to report SI information.

When the first carrier and the second carrier in the dual carrier report scheduling information respectively, the first carrier and the second carrier are respectively configured with a set of timers, and the two sets of timers work independently without affecting each other.

For using a set of timers to simultaneously trigger two carriers for SI reporting, the specific description is as follows:

Case 1 (Case 1):

Carrier 1: SG = "Zero_Grant" or all processes are inactive

Carrier 2: SG = "Zero_Grant" or all processes are inactive

If the TEBS becomes a value greater than 0, the reporting of dual-carrier SI information is triggered.

The arrival of higher priority data in the transmission buffer triggers the dual carrier to report SI information.

Configure an SI information cycle trigger timer T_SING, and start the timer T_SING5001 when both carrier 1 and carrier 2 satisfy SG="Zero_Grant" or all processes are in an inactive state. When the timer expires, the reporting of dual-carrier SI information is triggered. The timer is restarted after the reporting of dual-carrier SI information is triggered. During the timing period, if the state of Case 2 (Case2) or Case 3 (Case3) is entered due to a carrier SG or process state change, stop the T_SING timer and start the timer T_SIG at the same time. The timer needs to be restarted when SI is triggered and reported during the timing period.

Case 2 (Case 2)

Carrier 1: SG <> "Zero_Grant" and at least one process is active

Carrier 2: SG <> "Zero_Grant" and at least one process is active

If TEBS>0 and the SG of a certain carrier becomes too small to transmit a PDU of any MAC-d flow, or the current SG of both carriers is too small to transmit a PDU of any MAC-d flow, TEBS becomes a value greater than 0, triggering the reporting of dual-carrier SI information.

If the E-DCH serving cell of a certain carrier changes, and the new serving cell does not belong to the original serving E-DCH RLS, trigger reporting of dual-carrier SI information.

When at least one carrier satisfies SG<>"Zero_Grant" and at least one process is active, start the timer. When the timer expires, the reporting of the SI information of the dual carrier is triggered. After the reporting of the SI information of the dual carriers is triggered, the timer restarts. During the timing period, if the state of Case1 is entered due to the change of the state of the two carrier SGs or processes, trigger SI, stop the T_SIG timer, and restart the timer T_SING at the same time, if TEBS>0 at this time, trigger to report SI; 3 (Case3), T_SIG restarts. If the SI information is triggered to be reported during the timing period, restart the timer.

Case 3 (Case 3)

Carrier 1: SG="Zero_Grant" or all processes are inactive

Carrier 2: SG <> "Zero_Grant" and at least one process is active

TEBS becomes greater than 0 if TEBS > 0 and the SG of carrier 2 becomes too small to transmit a PDU of any MAC-d flow or the current SG of carrier 2 is too small to transmit a PDU of any MAC-d flow value, triggering the reporting of dual-carrier SI information;

If the E-DCH serving cell of carrier 2 changes, and the new serving cell does not belong to the original serving E-DCH RLS, trigger reporting of SI information of dual carriers.

When at least one carrier satisfies SG<>"Zero_Grant" and at least one process is active, start the timer T_SIG. When the timer expires, the reporting of the SI information of the dual carrier is triggered. After the reporting of the SI information of the dual carriers is triggered, the timer restarts. During the timing period, if the carrier SG or process state changes and enters the Case1 state, stop the T_SIG timer and restart the timer T_SING5001 at the same time. If TEBS>0 at this time, trigger the reporting of the SI information of the dual carrier; if it enters the Case2 state, the timing The T_SIG restarts. During the timing period, when the SI information of the dual carrier is triggered to be reported, the timer is restarted.

It should be noted that in case3, one carrier SG="Zero_Grant" or all processes are inactive, while another carrier SG<>"Zero_Grant" and at least one process is active, the timer T_SING can also be used .

Certainly, the event triggering unit 5001 may also trigger the dual carriers to report the scheduling information at the same time, or report the scheduling information separately, for example, when the HARQ transmission fails, it also triggers the reporting of the SI information of the dual carriers, specifically:

If the SI information is reported by the two carriers separately, wait for the periodic trigger of the timer, and report 18-bit SI information respectively.

Otherwise, two carriers report a 23-bit SI information.
