Description

Method, device and system for reporting scheduling information based on multi-carrier HSUPA The present application claims to be submitted to the Chinese Patent Office on March 30, 2010, the application number is 201010137806.7, and the invention is entitled "Multi-carrier HSUPA-based scheduling information reporting method, device and system" The priority of the Chinese Patent Application, the entire contents of which is incorporated herein by reference.

Technical field

The present invention relates to the field of communications, and in particular, to a method, device, and system for reporting scheduling information. Background technique

Currently, in the 3GPP Release 7 specification, the N-frequency feature is introduced in High Speed Uplink Packet Access (HSUPA), that is, a cell can have multiple working frequency points, and one of the working frequency points is mainly The frequency point, the other working frequency is the secondary frequency point, and the mobile station (UE) is the single carrier working mode; the working frequency point can be at the primary frequency point of the cell or at the secondary frequency point of the cell. The introduction of the N-frequency concept greatly enhances the user capacity of the system. At the same time, the N-frequency feature also lays the foundation for the introduction of multi-carrier characteristics in HSUPA.

Referring to Table 1, in the prior art, the configuration of the single-carrier HSUPA Scheduling Information (SI) is as follows:

Table 1

The total E-DCH Buffer Status (TEBS) indicates the cache amount, the HLBS (Highest ptriority Logical channel Buffer Status) indicates the cache ratio of the highest priority logical channel, and the HLID (Highest priority Logical Channel) indicates the ID of the highest priority logical channel. These three parts are generally referred to as buffer status information. UPH (UE Power Headroom) indicates the power headroom of the terminal, which is related to the carrier where the UE is located. SNPL (Serving and Neighbour Cell Pathloss) indicates the service area and neighboring path loss. The network deployment of the UE is related to the network frequency. Currently, the CELL-DCH shape under Radio Resource Control (RRC) The manner of triggering single-carrier SI reporting may be any of the following:

(1) When the UE buffer changes from 0 to greater than 0, the SI is reported to the network side;

(2) when the UE is in the handover and the buffer is not empty, report the SI to the network side;

(3) The authorization obtained by the UE times out, and the UE buffer is not empty. At this time, the timer T-WAIT is started. During the running of the T-WAIT, the UE stops and resets the T-WAIT when it receives the authorization again. After the authorization expires, After starting the T-WAIT, after the T-WAIT timeout expires, if there is no scheduling information authorization in the estimation window, the Enhanced Dedicated Channel Random Access Uplink Control Channel (E-RUCCH), also called E-DCH, is triggered. Random access to the uplink control channel, and sending the SI to the network side;

The E-RUCCH is a new uplink physical channel, and transmits related information (ie, SI) of the secondary base station scheduling sent by the user. When the UE does not have the authorized resource, the SI is transmitted on the E-RUCCH, and the UE has the authorized resource. The SI is carried in the transport block formed by the MAC layer and mapped to the E-DCH Physical Uplink Channel (E-PUCH).

(4) After the SI sends the media access control e-type protocol data unit (MAC-e PDU) or the medium access control i-type protocol data unit (MAC-i PDU), the timer T-SI is started, and the T-SI times out. Triggering the UE to send the SI through the E-PUCH; each time the SI is sent through the MAC-e PDU or the MAC-i PDU, the T-SI is restarted;

(5) If the transport block (TBS) selected by the UE using the E-DCH Transport Format Combination (E-TFC), in addition to carrying the data of the logical channel, there is still space remaining to fill the SI, then The corresponding MAC-e PDU or MAC-i PDU will carry one SI to the network side;

(6) When the UE receives higher priority logical channel data, it will trigger the transmission of SI in the MAC-e PDU or MAC-i PDU.

In the above six types of SI reporting methods, modes (1) and (2) are triggers of grant (grant request), modes (3) and (4) are timer triggers, and mode (3) is to avoid UEs in the working carrier. The method (4) is to avoid excessive time interval for the UE to report scheduling information on the carrier; the mode (5) is padding triggering; the mode (6) is high priority data. of Trigger.

With the development of technology, multi-carrier HSUPA is introduced into the system. The introduction of multi-carrier HSUPA can improve the uplink peak rate of users, so that its uplink rate can be combined with multi-carrier high-speed downlink packet access (HSDPA). ), so that the uplink and downlink rate symmetry can be achieved. In addition, the UE in the multi-carrier HSUPA system can use the carrier more flexibly with respect to the N-frequency characteristics.

However, compared with the single-carrier HSUPA at the N-frequency, the introduction of multi-carrier HSUPA brings many carrier-related technical problems, and the triggering of the SI reporting process under multi-carrier HSUPA is one of them. Since the multi-carrier characteristic is different from the single carrier, the triggering method of the SI reporting procedure under the single-carrier HSUPA is not applicable to the multi-carrier. However, the SI reporting trigger mechanism of the HSUPA system in the existing standard is based on single carrier research, and there is no research related to the multi-carrier SI reporting trigger mechanism, and the single carrier algorithm is not fully applicable to multi-carrier, therefore, multi-carrier resources The scheduling algorithm needs to be redesigned. Summary of the invention

In order to improve the timeliness and flexibility of the system resource scheduling in the multi-carrier HSUPA, the time division-synchronous code division multiple access (TD-Time Division) is used in the embodiment of the present invention. In the TD-SCDMA system, the user terminal starts to monitor each trigger condition corresponding to multiple carriers configured by the network side, where each trigger condition corresponds to a specified at least one carrier, where At least one carrier refers to at least one of carriers configured by the network side for the terminal; As a result, when it is determined that a certain trigger condition is satisfied, the scheduling information of all or part of the carriers obtained by the user terminal is sent to the network side by using at least one carrier corresponding to the trigger condition.

Specifically, the user terminal may set a trigger condition for the multiple carriers configured for the network side, and each trigger condition corresponds to the specified at least one carrier, and the user terminal monitors the set trigger conditions, and determines according to the monitoring result. When a certain trigger condition is met, the scheduling information of all or part of the carriers obtained by the user terminal is sent to the network side by using at least one carrier corresponding to the trigger condition.

Of course, the user terminal can also obtain the trigger conditions corresponding to the multiple carriers configured by the network side, and start to detect the trigger conditions, where the network side corresponds to multiple carriers configured for the network. Each trigger condition is obtained by the user terminal according to the configuration information of the carrier and the trigger condition saved by the user terminal, or each trigger condition corresponding to the multiple carriers configured by the network side is received from the network side.

Here, the trigger condition information corresponding to each carrier may be pre-configured on the terminal side, or the trigger condition information corresponding to the carrier group composed of multiple carriers may be configured. The trigger condition information may be negotiated by the user terminal and the network side, and the setting may be performed. When the trigger condition is used, the trigger condition information is directly used to determine the trigger conditions corresponding to the multiple carriers configured for the terminal on the network side, and the trigger conditions corresponding to multiple carriers configured for the terminal on the network side are started. Monitoring. The terminal may also receive the trigger condition information corresponding to the multi-carrier configured by the network side to determine the trigger condition corresponding to the multi-carrier configured by the network side, and start to monitor the trigger condition.

The user terminal sets a trigger condition for the multiple carriers configured for the network side, and each trigger condition corresponds to the specified at least one carrier, including: the user terminal divides the multiple carriers configured by the network side into at least one carrier group. And setting a corresponding trigger condition for each carrier group; or, the user terminal respectively sets a corresponding trigger condition for each of the multiple carriers configured by the network side; that is, the user terminal can use the carrier The scheduling information is reported in the group form, and the scheduling information can also be used in the carrier independent form.

On the other hand, each trigger condition corresponds to the specified at least one carrier, which means that the carriers corresponding to different trigger conditions are different, and one trigger condition may correspond to one carrier, or may correspond to a part of carriers, and may also correspond to all carriers. Example of setting the trigger condition as a timer: To avoid long time counts The specified carrier corresponding to the timer (T-SI) that is not provided with the scheduling information may be a part or all of the carriers allocated by the network side to the UE, where the data refers to a data packet carried by the E-PUCH or a MAC. -i PDU; The designated carrier corresponding to the timer (T-WAIT) set to avoid the UE having data to be transmitted but not receiving the network side scheduling authorization for a long time may be all carriers allocated by the network side for the UE.

In the actual application, the user terminal may report the scheduling information in the form of a carrier group or a carrier independent manner according to the high-level signaling indication on the network side or the execution mode pre-agreed by the network side and the terminal side. Further, the user terminal may further determine, according to the high-level signaling indication of the network side, or the execution mode pre-agreed by the network side and the terminal side, respectively, to set corresponding trigger conditions for each carrier group, or for each configured for the network side. The carrier sets the corresponding trigger condition separately. Further, the user terminal may classify all the obtained carriers into one carrier group according to an execution mode pre-agreed by the network side and the terminal side.

Preferably, the network side indicates to the UE by using specific identifier information. For example, the flag bit is “TRUE”, indicating that the UE needs to report scheduling information in the form of a carrier group, and the flag bit “FALSE” indicates that the UE needs to be carrier independent. The form separately reports the scheduling information; further, the network side may implicitly instruct the UE to perform scheduling information in the form of a carrier group or a carrier independently through a mutual relationship between certain signalings. On the other hand, the high layer signaling may be carried by the measurement control message, or may be carried by other dedicated signaling, or may be notified to the UE in a broadcast manner. In this way, after receiving the high-level signaling indication on the network side, the UE can determine whether to report the scheduling information in a carrier group or carrier-independent manner.

Based on the above principle, when the network side notifies the UE to report the scheduling information in the form of a carrier group, the UE may further notify the UE of the division manner of the carrier group. Preferably, the UE divides the multiple carriers configured by the network side into at least one carrier group according to the carrier group information configured by the received high layer signaling, or the UE performs the network according to the neighboring area information configured by the high layer signaling. The multiple carriers configured for the side are divided into at least one carrier group, or the UE divides all the obtained carriers into one carrier group according to a pre-agreed execution mode of the network side and the user terminal side.

For example, the network side notifies the carrier group information through the high layer signaling, and the purpose of all indication modes is to establish a mapping relationship between the carrier and its associated carrier group. Here are some examples of the specific instructions (but not limited to these implementations): (1) Clearly indicate the carrier included in each carrier group, as shown in Table 2,

Table 2

(2) Simplified indication, that is, the configuration information of the carriers belonging to the same group when the network side configures the carrier for the UE is set in consecutive positions in the signaling, that is, the configuration messages of these carriers are adjacent in the signaling. Specifically, as shown in Table 3:

table 3

The basic principle of the above indication manner is to continuously configure the configuration information of the carriers belonging to one carrier when carried in the signaling, and then use the bit string to indicate the mapping relationship. (3) Display indication, that is, when the network side configures a carrier for the UE, the carrier group number to which the carrier belongs is added in the configuration information. Specifically, as shown in Table 4:

Table 4

The indication signaling may be carried in the measurement control message, may also be carried by other dedicated signaling, or may be notified to the UE in a broadcast form.

In addition, the manner in which the UE divides the multiple carriers configured by the network side into at least one carrier group according to the neighboring area information configured by the high layer signaling includes: the UE analyzes all the carriers obtained by the UE one by one, and determines to calculate the carrier. Which cells are included in the SNPL, and when certain carriers (including only one carrier) use the same or similar neighbors when calculating the SNPL, the UE divides these carriers into the same carrier group.

In addition, the UE may further divide all the obtained carriers into one carrier group according to an execution mode pre-agreed by the network side and the terminal side, and one of the applications of the mode may be used for reporting extended scheduling information.

Preferably, when the network side needs the UE to report the scheduling information according to the carrier group, the radio network controller (RNC) notifies the base station of the carrier group information of all the carriers, so that the base station receives the scheduling information of the carrier group. The scheduling information of other carriers in the carrier group may be derived according to the scheduling information received on one carrier in the carrier group, and the manner is applicable to the extended scheduling information and the non-extended scheduling information, and the indication manner is It can be similar to the several indications exemplified above, and will not be described here. Further, the manner in which the RNC notifies the base station carrier group information may be: Or reconfiguration process, radio link (RL) setup or reconfiguration procedure, physical shared channel setup or reconfiguration procedure, common transport channel setup or reconfiguration procedure, carrier group information carried over Frame Protocol (FP) frames Wait. Preferably, the RNC may also notify the base station that the UE reports the scheduling information in a carrier group manner or reports the scheduling information in a carrier independent manner.

In the embodiment of the present invention, when reporting the scheduling information, the UE includes, but is not limited to, the following two methods: 1. Extending the content of the scheduling information under the single carrier based on the status of multiple carriers allocated by the network side, and expanding the content of the scheduling information The scheduling information is sent to the network side.

Among the parameters included in the scheduling information, the SNPL and the UPH are related to the working carrier of the UE. Therefore, as shown in Table 5, when the content of the scheduling information is extended based on the state of the multi-carrier, the UE needs to be used in multiple carriers for its own use. Each carrier is set with the corresponding SNPL and UPH. However, since the SNPL can be the same for some carriers, the UPH can be derived from some carriers. Therefore, the number of SNPL and UPH in the extended scheduling information is not fixed, that is, m is equal to n or m is not equal. n, and both m and n may be 1, while TEBS, HLBS, and HLID may be shared between different carriers.

Table 5 above is only an example of the extended scheduling information. The scheduling information may be extended in other multiple manners. The basic principle of the extension is to share the buffer status information between the carriers, and in the scheduling information. List the SNPL of each carrier or carrier group, and list the UPHs that fix one carrier or list the UPHs of the carriers carrying the scheduling information or list the UPHs of each carrier.

The extension of the scheduling information may enable the network-side base station to obtain scheduling information of all working carriers used by the UE at one time after receiving the scheduling information, thereby saving operation flow.

2. The length of the scheduling information is kept unchanged based on the single carrier system. That is, the content of the scheduling information is still set in the manner shown in Table 1, and the scheduling information of the multi-carrier is sent to the network side through multiple transmissions.

The preferred embodiments of the present application are described in detail below with reference to the accompanying drawings.

Based on the foregoing embodiment, referring to FIG. 1 , in the embodiment of the present invention, a TD-CDMA system inner packet includes a plurality of base stations and user terminals (ie, UEs), and the base station and the RNC interact through the Iub interface (when the network is flat During the evolution, the RNC is implemented in the same entity as the base station, and the Iub interface can be reserved or replaced by an internal communication interface. The RNC can have multiple base stations, and the base station can have multiple cells. The UE of each cell transmits data to the base station in a single carrier mode or a multi-carrier mode. In the process of transmitting data, the UE listens to the control channel carrying the scheduling grant information and the network. The side reports the scheduling information in time. The channel for reporting the scheduling information may be an E-RUCCH or an E-PUCH, and the channel carrying the scheduling grant information is an E-DCH Absolute Grant Channel (E-AGCH), and the channel that the base station feeds back to the E-PUCH. It is an E-DCH Hybrid ARQ Indicator Channel (E-HICH). among them,

The UE is configured to start, by using, triggering, for each trigger condition corresponding to multiple carriers configured by the network side, where each trigger condition corresponds to the specified at least one carrier; and determining that a trigger condition is satisfied according to the monitoring result. And transmitting, by using at least one carrier corresponding to the trigger condition, scheduling information of all or part of carriers obtained by the user terminal to the network side;

The user terminal is configured to set a trigger condition for the multiple carriers configured for the network side, where each trigger condition corresponds to the specified at least one carrier; the user terminal monitors the set trigger conditions; or

The user terminal is configured to obtain each trigger condition corresponding to the multiple carriers configured by the network side, and start to detect the trigger conditions, where the network side corresponds to multiple carriers configured for the network side. Each trigger condition is obtained by the user terminal according to the configuration information of the carrier and the trigger condition saved by the user terminal, or each trigger condition corresponding to the multiple carriers configured by the network side is received from the network side.

As shown in FIG. 2, in the embodiment of the present invention, the UE includes a control unit 13 and a reporting unit 12, and the control unit 13 is configured to start monitoring, for each trigger condition corresponding to multiple carriers configured by the network side, where Each trigger condition corresponds to the specified at least one carrier;

The reporting unit 12 is configured to: when determining that a certain trigger condition is met according to the monitoring result, send, by using at least one carrier corresponding to the trigger condition, scheduling information of all or part of carriers obtained by the user terminal to Network side.

The control unit may include: a setting unit 10 and a detecting unit 11. The setting unit 10 is configured to set a trigger condition for the multiple carriers configured for the user terminal on the network side, where each trigger condition corresponds to the specified at least one carrier, and the detecting unit 11 is configured to monitor the set trigger conditions;

In addition, the control unit may include: an obtaining unit and a detecting unit, not shown in the figure, the acquiring unit, configured to obtain each triggering condition corresponding to the multiple carriers configured by the network side, where the network side is The triggering conditions corresponding to the multiple carriers configured by the user terminal are obtained according to the configuration information of the carrier and the triggering condition saved by the user terminal, or the triggering conditions corresponding to the multiple carriers configured by the network side are The network side receives; the detecting unit is used to start monitoring each trigger condition.

The setting unit may be configured to divide the plurality of carriers configured by the network side into at least one carrier group for the plurality of carriers configured by the network side, and set respective corresponding groups for each carrier group. Trigger condition; or, for each carrier of the multiple carriers configured for the network side, respectively set corresponding trigger conditions.

When the setting unit divides the plurality of carriers configured by the network side into at least one carrier group, the plurality of carriers configured by the network side are divided into at least one carrier group according to the carrier group information configured by the received high layer signaling, Or, according to the neighbor information configured by the high-level signaling, the multiple carriers configured by the network side are divided into at least one carrier group; or, according to the execution mode pre-agreed by the network side and the user terminal side, all the obtained carriers are divided into A carrier group.

The reporting unit may determine, according to the detection result, that the triggering condition corresponding to any one of the at least one carrier group that is divided by the setting unit is satisfied, and send the scheduling information on the carrier that first receives the scheduling authorization in the carrier group. Or transmitting a scheduling information on a certain carrier that is fixed in the carrier group. When the trigger condition corresponding to any one of the carriers included in the wave is satisfied, the scheduling information is transmitted on any one of the carriers.

When the reporting unit sends the scheduling information, the content of the scheduling information of the single carrier may be extended by referring to the status of all or part of the carriers, and the extended scheduling information is sent to the network side; or The scheduling information of the multiple carriers is sent to the network side by multiple transmissions.

When the reporting unit sends extended or non-extended scheduling information, the enhanced physical uplink channel

In the data packet transmitted by the E-PUCH, the space carrying the scheduling information is reserved first, and then the data packet is filled.

When the reporting unit sends the extended or non-extended scheduling information, it first detects the remaining space of the currently formed data packet on the enhanced physical uplink channel E-PUCH, and determines that the remaining space is sufficient to carry the extended scheduling information, and then expands The scheduling information is carried in the data packet and sent to the network side. When the remaining space is insufficient to carry the extended scheduling information, the extended partial scheduling information or the non-extended scheduling information is carried in the data packet and sent to the network side. .

Based on the foregoing system architecture, referring to FIG. 3, in the embodiment of the present invention, the detailed process of reporting scheduling information (SI) by the UE to the network side is as follows:

Step 300: The UE sets a trigger condition for multiple carriers configured for the network side, and each trigger condition corresponds to the specified at least one carrier.

In this embodiment, the UE may divide the obtained multiple carriers into carrier groups, report the scheduling information in the form of a carrier group, or perform scheduling information on the carrier independent form on the obtained multiple carriers. The UE may be configured to divide the multiple carriers configured by the network side into at least one carrier group according to the carrier group information configured by the received high-level signaling, where the carrier group information is the carrier and the carrier group to which the carrier belongs. Or the mapping between the multiple carriers configured by the network side according to the neighboring area information configured by the high-level signaling into at least one carrier group; or, the UE pre-agreed according to the network side and the user terminal side. The execution mode divides all the obtained carriers into one carrier group.

For example, the UE derives the carrier group according to the cell list configured by the network side, for example, determines the SNPL of each carrier for multiple carriers allocated to the UE by the network side, and sets the SNPLs equal or similar (ie, the difference is in the set range. The carriers are internal to the same carrier group. For another example, the UE searches for the neighboring cells required for calculating the SNPL for each carrier for multiple carriers configured on the network side. If the neighboring regions required by some carriers are identical, the UEs are assigned to the same carrier group.

For example, when the network side high layer signaling indicates that the UE divides the carrier group, the carrier group can be grouped by means of a bit string. For example, when the frequency point is configured for the base station, the frequency points belonging to the same group are continuously configured, and then The special string is displayed in the form of "0" and "1", and the adjacent and identical bits represent the same frequency group, such as: "00010011" means: the first to third carriers of the configuration are a group, The four carriers are a single group, the fifth and sixth carriers are a group, and the seventh and eighth carriers are a group. Of course, the bit string indication manner has other forms, but only the coding methods are different, different The encoding method represents the same mapping relationship. The multiple carriers that are configured for the base station on the network side can be regarded as a complete set, and each carrier group maintained by the UE is a subset of the multiple carriers, and each carrier group maintained by the base station is also corresponding to the UE side maintenance. The complete set of carrier groups.

Step 310: The UE monitors each set trigger condition.

Step 320: The UE sends the scheduling information of all or part of the carriers obtained by the UE to the network side by using at least one carrier corresponding to the triggering condition, according to the monitoring result. The scheduling information of all or part of the carrier includes: scheduling information of the carrier that sends the scheduling information, or scheduling information of a fixed carrier agreed by the network side and the terminal side, or extension of all or part of the carrier obtained by the UE. Scheduling information.

In this embodiment, the UE determines, according to the monitoring result, that the trigger condition corresponding to any one of the carrier groups in each carrier group is satisfied, and sends the scheduling information on the carrier that first receives the scheduling authorization in the carrier group, or Preferably, the carrier that is scheduled to receive the scheduling grant refers to the carrier that first receives the scheduling grant in the next time from the timer timeout; Preferably, the UE performs scheduling information transmission on the carrier when the trigger condition corresponding to any one of the plurality of carriers obtained by the UE is determined according to the monitoring result.

In the above embodiment, the trigger conditions set by the UE in step 300 include but are not limited to the following:

1. Timer T-SI times out. That is, when the timer T-SI times out, the UE sends scheduling information of all or part of the carriers obtained by the UE to the network side. The T-SI is configured to prevent the UE from carrying the scheduling information in the data transmitted on the at least one carrier corresponding to the T-SI within the T-SI limited duration.

Taking the carrier group as an example, the maintenance method of the T-SI of a carrier group is: when the UE obtains scheduling authorization on any carrier in the carrier group, the timer starts; when the scheduling information is in any one of the carrier groups The T-SI is carried and transmitted in the data of the carrier's traffic channel (E-PUCH or MAC-I PDU) Restart now. The length of the T-SI is configured by the network side. Each carrier group can be configured with an independent T-SI duration or a uniform T-SI duration.

Taking carrier independence as an example, the T-SI maintenance method of a carrier is: when the UE obtains scheduling grant on the carrier, the timer starts; when the scheduling information is in the traffic channel data of the carrier (E-PUCH or MAC- When the I PDU is carried and transmitted, the T-SI restarts immediately. The duration of the T-SI is configured by the network side. Each carrier can be configured with an independent T-SI duration or a uniform T-SI duration.

For example, the T-SI maintenance of the extended scheduling information is as follows. The maintenance method of the T-SI is as follows: When the UE obtains scheduling authorization on any carrier, the timer starts; when the scheduling information is in the traffic channel data of any carrier (E- When carried and transmitted in PUCH or MAC-I PDU), the T-SI restarts immediately. The duration of the T-SI is configured by the network side.

2. The timer T-WAIT is used to prevent the user terminal from having data to be sent. The network side scheduling authorization is not obtained on all carriers within the T-WAIT limit duration. The T-WAIT timer expires and the UE buffer is greater than 0. The UE will send the scheduling information of all or part of the obtained carriers to the network side through the designated channel (for example, the E-DCH random access uplink control channel). When the UE sends the scheduling information through the E-DCH random access uplink control channel, the scheduling information includes the scheduling information of the carrier to which the E-DCH random access uplink control channel belongs, or the scheduling information of the specified carrier that the network side and the terminal side agree to report. Or extended scheduling information.

In this embodiment, the method for the UE to maintain the T-WAIT is as follows: After the scheduling information is carried and transmitted from the E-DCH random access uplink control channel, the T-WAIT will stop and reset; when all the working carriers of the UE in one TTI are When the scheduling authorization is not available, and the buffer is greater than zero, the T-WAIT is started; when at least one carrier of the UE in a TTI is scheduled to be authorized, the T-WAIT will stop and reset.

Preferably, the network side configures the E-DCH random access uplink control channel for the UE on one carrier or multiple carriers, and the network side configures the E-DCH random access uplink control channel for the UE only on one carrier. . The network side can be configured with only one E-DCH random access uplink control channel for the UE, and the E-DCH random access uplink control channel configured for different UEs is distributed on different carriers, so as to prevent different UEs from selecting the E-DCH randomly. When the uplink control channel is transmitted to transmit scheduling information, a collision occurs due to selection of the same carrier. Of course, the network side can still configure a set of E-DCH random access for the UE. The control channel is selected. When the UE transmits the scheduling information, the E-DCH random access uplink control channel (which may belong to different carriers) is selected. The selection principle may be that the interference size is selected, or the subframe number is modulo, or randomly selected. .

In the foregoing embodiment, when the UE determines that the trigger condition is satisfied in step 320, the UE may use the following at least one carrier corresponding to the trigger condition to send the obtained scheduling information of all or part of the carrier to the network side. Any method (taking the carrier group as an example):

1) In the current carrier group, the UE selects the carrier reporting scheduling information that first receives the scheduling grant, and carries the scheduling information by using the E-PUCH or MAC-I PDU of the carrier.

2) The scheduling information is reported by a certain carrier in the fixed selection carrier group, and the scheduling information is carried by the E-PUCH or MAC-I PDU of the carrier.

Preferably, the first receiving the scheduling grant may refer to the carrier that first receives the scheduling grant after the timer expires.

Preferably, after determining the carrier carrying the scheduling information, the UPH included in the scheduling information may be the UPH of the carrier group, or may be the UPH of the specified carrier; and the SNPL included in the scheduling information may be the carrier. The SNPL of the group can also be the SNPL of a given carrier.

Similarly, when reporting scheduling information in a carrier-independent manner, the UE may also set a timer T-SI for each of the obtained multiple carriers, and use the T-SI timeout as a precondition for triggering the scheduling information. condition.

Preferably, the UE maintains a single T-SI for each carrier to prevent the UE from carrying the scheduling information for a long time when transmitting data on the corresponding carrier. The duration of the T-SI is configured by the network side, and can be configured for each carrier. The independent T-SI duration can also be configured with a uniform T-SI duration for multiple carriers.

Preferably, the method for maintaining the T-SI of each carrier is: when the UE obtains the scheduling grant of a certain carrier, the T-SI of the carrier is started, and the data of the UE in the traffic channel of the carrier (E-PUCH or When the MAC-I PDU carries the scheduling information of the carrier and transmits, the corresponding T-SI restarts immediately.

Similarly, when the extended scheduling information is reported, the UE may set a timer T-SI for all the obtained carriers, and use the T-SI timeout as a precondition for triggering the reporting of the scheduling information.

Preferably, the UE maintains one T-SI for all carriers to prevent the UE from transmitting data for a long time. The scheduling information is not carried in between; the duration of the T-SI is configured by the network side.

Preferably, the method for maintaining the T-SI when the extended scheduling information is reported is: when the UE obtains the scheduling grant of any carrier, the T-SI starts, and the data of the service channel of the UE in any one carrier (E- When the PUCH or MAC-I PDU carries the scheduling information and transmits, the corresponding T-SI restarts immediately.

Based on the foregoing embodiment, when the UE sends the scheduling information to the network side, the space for carrying the scheduling information is reserved in the data packet transmitted by the E-PUCH, and then the data packet is filled. The UE may carry extended or non-extended scheduling information through the E-PUCH data packet; the UE may carry scheduling information on the latest data transmitted on the carrier or carry scheduling information on a fixed carrier.

In an actual application, in the process of reporting the extended scheduling information, when the transport block size TBS selected by the UE using the E-DCH transport format combination (E-TFC) is insufficient to carry the extended scheduling information, the following may be used. Two solutions:

(1) The UE may carry only non-extended scheduling information in the E-PUCH data packet. Preferably, the scheduling information may be scheduling information of a fixed carrier, or scheduling information of a carrier carrying the non-extended scheduling information.

When the network side receives the uplink data, when the transport block size can carry the extended scheduling information, the base station determines whether there is scheduling information according to the header information of the data packet. When the transport block size cannot carry the extended scheduling information, the base station according to the TBS size. Determining that the scheduling information is non-extended scheduling information, and determining a carrier attribute of the scheduling information according to the same manner as the UE;

Preferably, the timer T-SI maintained by the user terminal for all carriers may not be restarted, so that the extended scheduling information may continue to be carried in the next data transmission, or may be restarted to avoid when the channel conditions are poor. Continuously triggers extended scheduling information, thereby reducing data transmission efficiency.

(2) Limiting the sub-small data block size (TBS=116) in the transport block table or a larger TBS is the TBS that E-TFC always supports, in order to avoid the situation that the extended scheduling information cannot be carried. The method includes: when the UE is scheduled to be authorized, the UE determines that the extended scheduling information needs to be carried in the data, and the UE adjusts the minimum supported TBS that is always supported by the E-TFC. Preferably, the method for adjusting the minimum supported TBS is To: set all TBSs in the TBS table that are less than or equal to the minimum TBS that can carry the extended scheduling information to the E-TFC that is always supported; or, the UE uses the E-TFC to select The TBS carries the extended scheduling information, and agrees on the value of the smallest TBS that is always supported (for example, TBS== TBS=116); or, adjusts the minimum TBS value in the TBS table in advance (for example, TBS=23 The index is modified to the extended scheduling information length. When the UE is scheduled to be authorized and the UE determines that the extended scheduling information needs to be carried in the data, the UE uses the TBS selected by the E-TFC to carry the extended scheduling information in the E-PUCH.

The following describes the Transport Block Size TBS selected by E-TFC as an example. The process of forming a data packet is as follows:

Step 1: Select the appropriate TBS according to the E-TFC, assuming that TBS=1000, indicating that the information bits and the header information and the number of padding bits that the E-PUCH can carry are 1000 in total.

Step 2: According to the TBS group data packet, the data and the header information are filled in the order of priority from high to low. If the timer triggers the scheduling information, the data is filled with the highest priority, if it is for padding. The scheduling information has the lowest priority. The scheduling information with the highest priority should reserve a space for scheduling information in the data packet. If there is remaining space in the data, a low-priority scheduling information is carried in the piggybacking. The scheduling information is space-free, depending on whether the data block has space. If there is any remaining, it can be filled with redundant bits.

For the extended scheduling information, the E-TFC selection process needs to be modified in the above manner, so that the selected TBS can load the next extended scheduling information when the extended scheduling information needs to be installed.

For the extended scheduling information, when the scheduling information is piggybacked, it will encounter the problem that the remaining space can be loaded with the extended scheduling information. In this case, how much extended scheduling information can be carried with the extended scheduling information.

When the scheduling information is preferentially loaded in the group package, the placement information of the scheduling information is at the end of the data packet.

In the above step 1, the principle for E-TFC selection is:

Step 1: The UE receives resources authorized by the network, including power resources (PRRI), code channel resources (CRRI), and time slot resources (TRRI).

Step 2: The UE determines the gain factor according to the code channel resources configured on the network side. _e . The maximum value of the power offset (PO) of the MAC stream selected by the UE for the network is selected as the E-TFC. Power offset, based on the maximum and minimum code rates of the network configuration as the maximum and minimum code rate for limiting E-TFC selection;

Step 3: Determine the status of all TBSs; support or not support; judgment conditions are:

The code rate corresponding to the TBS value corresponds to 3⁄4, _e + PO <= PRRI, and 3⁄4, _e + PO + L + « _e < Pmax, and meets the maximum and minimum code rate limits and modulation mode requirements; the smallest TBS is TBS = 23 is forever supported.

Where Pmax is the maximum value of the uplink transmit power.

Step 4: Select all the largest TBSs in the supported state as the TBS selected by the E-TFC. Different from the foregoing manner of reserving the free space on the E-PUCH, in another case, when the UE sends the scheduling information to the network side, the UE may also carry the extended or non-padding manner through the E-PUCH data packet. The extended scheduling information includes: detecting the remaining space of the currently formed data packet on the E-PUCH, and determining that the remaining space is sufficient to carry the extended scheduling information, and carrying the extended scheduling information in the data packet and sending the data to the network side When it is determined that the remaining space is insufficient to carry the extended scheduling information, the extended partial scheduling information or the non-extended scheduling information is carried in the data packet and sent to the network side.

Preferably, the operation of the UE may be specifically performed in the following operations (only the example may describe that the extended scheduling information or the non-extended scheduling information may be carried when the free space is insufficient, or the scheduling information is not carried, and the operation may be further subdivided. ):

If the E-PUCH has a free space, the extended scheduling information may be carried, and the extended scheduling information is carried. If the free space of the E-PUCH cannot carry the extended scheduling information, but the non-extended scheduling information may be carried, the non-extended scheduling information is filled. The scheduling information is the scheduling information of the carrier in which the carrier is located. The specific mode may be selected by the high layer signaling or may be pre-agreed by the network side and the terminal side.

If the free space of the E-PUCH is insufficient to carry the non-extended scheduling information, the information fields of the TEBS, the HLBS, and the HLID are preferentially carried; or the free space does not carry the scheduling information.

When the base station receives the uplink data, when the TBS can carry the extended scheduling information, the base station determines whether there is scheduling information according to the header information of the data packet. When the TBS cannot carry the extended scheduling information, the base station determines the scheduling information according to the TBS size. Extended scheduling information, and the carrier attributes of the scheduling information are determined in the same manner as the agreed UE. In summary, in the embodiment of the present application, the triggering and carrying method of the scheduling information reporting based on the multi-carrier feature is introduced in the HSUPA system, and the scheduling information of the multi-carrier can be reported to the network side in time and accurately, thereby improving system resource utilization. Flexibility in efficiency and resource scheduling. Specifically:

Reporting the scheduling information by the carrier group and reporting the extended scheduling information can reduce the reporting of redundant information, improve resource utilization, and uniformly trigger the timer through all carriers to avoid that all carriers of the user terminal cannot get the network within the timer duration. The scheduling of the side can reduce the transmission probability of the E-RUCCH, and limit the E-RUCCH of any one UE to be transmitted on only one carrier, and configure the E-RUCCHs of different UEs on different carriers, which can reduce different UEs. When the E-RUCCH is selected to transmit to the same carrier, interference and collision can be avoided, and the working mode can be indicated by means of high-level signaling indication, which can bring flexibility to the network working and implementation of each vendor. Therefore, scheduling by the present invention The information reporting method can also improve resource utilization efficiency and flexibility when scheduling information is reported.

Further, the technical solution provided by the embodiment of the present application also has good backward and forward compatibility, for example, compatible with both the HSPA subsequent evolution system and the single carrier HSUPA system. The spirit and scope of the Ming. Thus, it is intended that the present invention cover the modifications and variations of the inventions
