## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of International Application No. PCT/CN2012/081438, filed on Sep. 14, 2012, which claims priority to International Application No. PCT/CN2012/072439, filed on Mar. 16, 2012, both of which are hereby incorporated by reference in their entireties.


TECHNICAL FIELD
The present invention relates to the resource configuration technology, and more particularly to, a method for configuring resources, a device and a system, and belongs to the field of communication technology.
BACKGROUND
As smart phones become increasingly popular, some non-traditional services, such as a background service and an instant messaging service featured by a small data packet and a long data packet inter-arrival time are becoming increasingly prevalent.
When such relatively isolated small data packet arrives, a user equipment (0) is usually in a radio resource control protocol (Radio Resource Control, RRC) connection release state (i.e., idle state) or RRC connection setup but out of synchronization state, because there is no data transmission for a long time, and therefore, when there is data to be sent, the UE needs to perform a random access process and complete uplink synchronization first, and then perform data transmission; in order not to repeat the above process every time there is data transmission subsequently, a physical layer radio resource configured by a network side for the UE are usually acquired through an RRC connection setup/reconfiguration process, so as to perform subsequent uplink transmission according to the physical layer radio resource configured by the network side.
It can be seen that, since the physical layer radio resource configured by the network side for the UE to perform uplink transmission are acquired through the RRC connection setup/reconfiguration process, every time the UE performs service data transmission, a long delay is thus caused, and the transmission efficiency is greatly reduced.

DESCRIPTION OF EMBODIMENTS
The technical solutions in the embodiments of the present invention are hereinafter described clearly with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described here are part of the embodiments of the invention and not all of the embodiments. All other embodiments, which can be derived by persons skilled in the art from the embodiments given herein without creative efforts, shall fall within the protection scope of the present invention.
Technical solutions of the embodiments of the present invention can be applied to any network system, and a long term evolution (Long Time Evolution, LTE) network will be described hereinafter as an example to illustrate the embodiments of the present invention.
Embodiment 1
FIG. 1 is a system architectural diagram of a typical LTE network. As shown in FIG. 1, a UE and a network side are included, where the network side includes, for example, an evolved Node B (e-NodeB, eNB for short hereinafter). The method for configuring resources according to Embodiment 1 of the present invention is performed by the network side, such as an eNB.
FIG. 2 is a schematic flowchart of a method for configuring resources according to an embodiment of the present invention. As shown in FIG. 2, the method for configuring resources includes steps as follows:
Step S201, Generating resource configuration information;
Step S202, Carrying the resource configuration information in a media access control (Media Access Control, MAC) protocol data unit (Protocol Data Unit, PDU) or in a physical downlink control channel (PDCCH) signaling and sending to a UE, to enable the UE to perform uplink transmission according to the resource configuration information.
Specifically, in the method for configuring resources according to this embodiment, the eNB can allocate a physical layer radio resource for performing uplink transmission and generate resource configuration information for the UE by an arbitrary rule or manner; and moreover, different physical layer radio resources can be allocated for different uplink information sent by the UE, the embodiment does not limit it.
In the LTE system, the interface between the eNB and the UE is a Uu interface, an MAC layer of the eNB generates an MAC PDU according to the resource configuration information and then sends the MAC PDU to a physical layer, and then the MAC PDU is processed by the physical layer and then sent to the UE through the Uu interface. FIG. 3 is a schematic structural diagram of a typical MAC PDU. As shown in FIG. 3, one MAC PDU includes an MAC header (MAC header) and an MAC payload (MAC payload), where the MAC payload includes an MAC service data unit (Service Data Unit, SDU), an MAC control element (Control Element, CE) and an optional (opt) padding bit (padding). The MAC layer of the eNB can carry resource configuration information in the MAC PDU, for example, by writing the resource configuration information in an MAC CE field. The resource configuration information can be expressed in the MAC CE in an arbitrary manner, for example, following the current manner of expression in the RRC message, and this embodiment is not limited thereto.
After receiving the MAC PDU containing the resource configuration information, the UE acquires the MAC CE from the received MAC PDU, and determines the corresponding physical layer radio resource according to the information carried in the MAC CE.
Carrying the resource configuration information in the MAC PDU is taken as an example for illustration in the above, similarly, the eNB also can carry the resource configuration information in the PDCCH signaling, and the specific carrying format can be set as required, and this embodiment is not limited thereto.
In the method for configuring resources according to this embodiment, the eNB carries the resource configuration information in the MAC PDU or the PDCCH signaling after configuring resources and generating resource configuration information for the UE, and sends the MAC PDU or the PDCCH signaling to the UE, to enable the UE to perform corresponding uplink transmission by processing the MAC PDU or the PDCCH signaling. Since the eNB and the UE can complete the MAC PDU or the PDCCH signaling processing using the MAC layer and the physical layer, or only using the physical layer, there is no need to occupy the RRC signaling, and therefore, signaling consumption is low, processing efficiency is high and delay is short, and the configuration efficiency for the physical layer radio resources is improved greatly.
Further, in the method for configuring resources in the above embodiment, the resource configuration information is scheduling request (Scheduling Request, SR) resource configuration information, uplink pilot signal (SRS) resource configuration information, or channel quality indicator information (CQI) resource configuration information. Illustrations will be made in detail hereinafter with respect to the three kinds of resource configuration information respectively.
I. SR Resource Configuration Information
SR is information sent by a UE in uplink to request an uplink transmission resource. In order to make sure the UE sends the scheduling request on a suitable and available resource, the eNB needs to perform configuration for uplink scheduling request for the UE in advance, so as to allocate a currently available scheduling request resource to the UE for sending the scheduling request, and notify the UE of a configuration result for the scheduling request (i.e., resource configuration information). In this way, when there is a need to perform data transmission, the UE can determine its own scheduling request resource allocated by the eNB, according to the configuration result, so as to send an uplink scheduling request with the allocated scheduling request resource. In the method for configuring resources according to this embodiment, the eNB can allocate a scheduling request resource and generate resource configuration information for the UE by an arbitrary rule or manner, and the embodiments of the present invention are not limited thereto.
More specifically, for example, the resource configuration information carried in the MAC CE can be: a scheduling request resource period, a subframe in the scheduling request resource period allocated for the user equipment, and a physical uplink control channel (PUCCH) resource for bearing the scheduling request. Particularly, the scheduling request resource period is a cycle period available for the UE to transmit the SR, which is determined by the eNB according to service status of UEs within the cell; the subframe in the scheduling request resource period is an uplink subframe available for the UE to transmit the SR within the period, that is, a specific location of the SR in one period; the PUCCH is for the UE to transmit the scheduling request on the uplink, that is, to notify the UE which PUCCH is used to transmit the scheduling request, such as a time, a frequency and a code resource, by configuring for UE the PUCCH resource for bearing the scheduling request.
The resource configuration information can be expressed in the MAC CE, for example, following the current manner of expression in the RRC message, that is:
The SR-ConfigIndex: i.e. periodicity and offset [0_157]:8 bit
SR-PUCCH-ResourceIndex [0-2047]: 11 bit
That is, if there are 158 combinations of the scheduling request resource period and the subframe in the corresponding period in total (for example, period 10 and subframe 0 is one combination), a possible range is [0, 157], a possible range of PUCCH is [0, 2047], then in the MAC CE, 8 bits (bit) can be used to identify the scheduling request resource period and the subframe in the scheduling request resource period allocated for the UE, 11 bits can be used to identify the PUCCH for bearing the scheduling request allocated for the UE.
After the MAC PDU containing the SR resource configuration information is received, the UE acquires the MAC CE from the received MAC PDU, and determines the corresponding SR resource according to the information carried in the MAC CE.
II. SRS Resource Configuration Information
SRS is a sequence transmitted by the UE in uplink, to enable the eNB to detect uplink channel quality by receiving the sequence. Accordingly, in order to realize detection of the uplink channel quality, a network side needs to allocate in advance a physical layer radio resource for the UE to transmit the SRS, i.e., a SRS resource. In this way, the UE can transmit the SRS in uplink according to the SRS resource allocated by the network side, so that the eNB can complete detection of the uplink channel quality, and thus subsequent scheduling can be performed according to the detected uplink channel quality.
More specifically, for example, the resource configuration information carried in the MAC CE can be: an SRS resource period, a subframe in the SRS resource period allocated for the user equipment, and an SRS resource for bearing the SRS, for example, including one or more of a frequency domain position, a bandwidth, an antenna port number, and etc of the SRS. Particularly, the SRS resource period is a cycle period available for the UE to transmit the SRS; the subframe in the SRS resource period is an uplink subframe available for the UE to transmit the SRS within the period, that is, a specific location of the SRS in one period.
The resource configuration information can be expressed in the MAC CE, for example, following the current manner of expression in the RRC message, and no details will be given here.
After receiving the MAC PDU containing the SRS resource configuration information, the UE acquires the MAC CE from the received MAC PDU, and can determine information, such as the SRS resource period, the subframe in the SRS resource period allocated for the user equipment, and the frequency domain position and the bandwidth etc of an SRS channel, according to the information carried in the MAC CE, and the UE can periodically transmit the SRS via the channel and in the designated subframe of the SRS resource period.
III. CQI Resource Configuration Information
CQI is for transmitting downlink channel quality indicator information in uplink after a UE performs detection of downlink channel quality. In order to make the UE be able to effectively report the downlink channel quality, to enable the eNB to successfully acquire the downlink channel quality, the network side needs to allocate in advance a physical layer radio resource for the UE to transmit the CQI in uplink, i.e., a CQI resource. In this way, the UE can transmit the detected downlink channel quality in uplink via the CQI according to the CQI resource allocated by the network side, so that the eNB can the acquire the downlink channel quality by receiving the CQI, and thus perform subsequent scheduling according to the downlink channel quality.
More specifically, for example, the resource configuration information carried in the MAC CE can be: a CQI resource period, a subframe in the CQI resource period allocated for the user equipment, and a PUCCH resource for bearing the CQI. Particularly, the CQI resource period is a cycle period available for the UE to transmit the CQI; the subframe in the CQI resource period is an uplink subframe available for the UE to transmit the CQI within the period, that is, a specific location of the CQI in one period; the PUCCH is for the UE to transmit the CQI in uplink, that is, the UE is notified which PUCCH is used to transmit the CQI, such as a time, a frequency and a code resource, by configuring for the UE the PUCCH resource for bearing the CQI.
The resource configuration information can be expressed in the MAC CE, for example, following the current manner of expression in the RRC message, and no details will be given here.
After receiving the MAC PDU containing the CQI resource configuration information, the UE acquires the MAC CE from the received MAC PDU, and can determine the corresponding CQI resource according to the information carried in the MAC CE.
Carrying the SR resource configuration information/SRS resource configuration information/CQI resource configuration information in the MAC PDU is taken as an example for illustration, similarly, the eNB also can carry the SR resource configuration information/SRS resource configuration information/CQI resource configuration information in the PDCCH signaling, and the specific carrying format can be set as required, and is not limited herein.
FIG. 4 is a schematic flowchart of performing UE service data transmission with a method for configuring resources according to an embodiment of the present invention. The SR resource configuration information is taken as an example of the resource configuration information for illustration in FIG. 4. As shown in FIG. 4, the RRC connection with the eNB has been set up currently but in a out of synchronization state, then a random access process is performed to complete uplink synchronization with the eNB; the UE acquires SR resource configuration information allocated by the network side for the UE through the MAC PDU or PDCCH interaction with the eNB; when the UE has one or more data packets to be transmitted in uplink, but without a uplink resource for uplink data transmission, the UE determines a corresponding SR resource according to the SR resource configuration information to transmit the SR in uplink, so as to acquire the uplink resource for uplink data transmission and complete the uplink data transmission. After completion of the data transmission, the UE also can release the SR resource according to a preset releasing rule.
When the UE performs service data transmission, in addition to the SR resource, the physical layer radio resource required by the UE may also include relevant information such as CQI and/or SRS, and the information either can be configured in an existing arbitrary configuration mode, or can be configured quickly with the method for configuring resources according to the embodiments of the present invention.
In the method for configuring resources according to this embodiment, the eNB carries the resource configuration information in the MAC PDU or the PDCCH signaling after configuring resources and generating resource configuration information for the UE, and sends the MAC PDU or the PDCCH signaling to the UE, so that the UE can acquire the physical layer radio resource by processing the MAC PDU or the PDCCH signaling and then perform corresponding uplink transmission. Since the eNB and the UE can complete the MAC PDU or the PDCCH signaling processing using the MAC layer and the physical layer, or only using the physical layer, there is no need to occupy the RRC signaling, and therefore, signaling consumption is low, processing efficiency is high and delay is short, and the configuration efficiency for the resources is improved greatly.
In addition, when the service data transmission of UE is performed using the method for configuring resources according to this embodiment, since physical layer radio resource configuration can be quickly achieved using the MAC PDU or the PDCCH signaling during the process of service data transmission, compared with the current method for acquiring the physical layer radio resource using an RRC reconfiguration procedure, there is no need to process a packet data convergence protocol (PDCP, Packet data convergence protocol) layer and a radio link control (RLC, Radio link Contro) protocol layer, therefore, the required signaling is significantly reduced, delay is shortened, and transmission efficiency of the service data is improved.
Embodiment 2
On the basis of Embodiment 1, the resource configuration information includes first resource configuration information and second resource configuration information;
correspondingly, before carrying the resource configuration information in the MAC PDU and sending to the user equipment, the method further includes:
before carrying the resource configuration information in the MAC PDU and sending to the user equipment, the method further includes:
sending the first resource configuration information to the user equipment in advance through an RRC message, or presetting the first resource configuration information in the user equipment;
the carrying the resource configuration information in the MAC PDU or the PDCCH signaling and sending to the user equipment specifically includes:
setting the second resource configuration information in the MAC PDU or the PDCCH signaling and sending to the user equipment.
In this embodiment, the first resource configuration information and the second resource configuration information being configuration information of different parameters related to the scheduling request resource is taken as an example for illustration.
Specifically, for example, when the resource configuration information includes configuration information of three parameters of a scheduling request resource period, a subframe in the scheduling request resource period allocated for the user equipment, and a PUCCH resource for bearing the scheduling request, the MAC PDU or the PDCCH signaling carries configuration information of only one or two parameters of the three parameters, while the previously interacted RRC message between the eNB and the UE carries configuration information of the remaining parameters, the previously interacted RRC message is, for example, a RRC connection setup message or the RRC reconfiguration message sent by the eNB to the UE when the UE and the eNB sets up the RRC connection for the first time.
More specifically, for example, when the UE and the eNB set up the RRC connection for the first time, the RRC connection setup message or the RRC reconfiguration message sent by the eNB to the UE carries a scheduling request resource period, the UE acquires the scheduling request resource period from the RRC connection setup message or the RRC reconfiguration message, since the UE fails to acquire the remaining information of the SR resources at this time, and then fails to acquire a SR resource, therefore, the scheduling request resource period is stored in the UE only as a parameter, does not occupy a radio resource actually, and thus the parameter of the scheduling request resource period will not be affected when the RRC resource is released.
When the UE needs to send uplink data and acquire configuration information of parameters related to the SR resource except the scheduling request resource period, that is, such as a subframe in the scheduling request resource period and a PUCCH resource for bearing the scheduling request, the UE can combine configuration information of the parameters related to the SR resource acquired from the MAC PDU or the PDCCH signaling with the previously acquired scheduling request resource period to form integrate SR resource configuration information, so as to determine the SR resource, and then transmit the SR in uplink with the determined SR resource.
Although the above process is described by taking the SR resource as an example, persons skilled in the art should appreciate that, the first resource configuration information and the second resource configuration information also can respectively include configuration information of a part of parameters for the SRS resource, or configuration information of a part of parameters for the CQI resource.
In the method for configuring resources in this embodiment, a part of the resource configuration information is allocated to the UE through the RRC message or preset in the UE, and such can reduce the number of bits occupied by the resource configuration information in the MAC PDU or the PDCCH signaling.
Further, in the above embodiment, it can be pre-agreed in a communication protocol between the UE and the eNB that resource configuration is achieved through the MAC PDU or the PDCCH signaling, so as to further reduce the number of bits occupied by the resource configuration information in the MAC PDU or the PDCCH signaling. Hereinafter, the SR resource is taken as an example for illustration. The same rule is also applicable to SRS and CQI.
Specifically, for example, in terms of 2047 PUCCH resources, it is agreed in the protocol that only 16 PUCCH resources therein can be configured through the MAC PDU or the PDCCH signaling. Therefore, when the eNB performs scheduling resource configuration for the UE using the method according to the embodiments of the present invention, configuration with respect to the PDCCH resource can only select from the 16 agreed PUCCH resources, therefore, only 4 bits in the MAC PDU or the PDCCH signaling need to be occupied for identifying the selected PDCCH resource, and 7 bits are saved compared with the occupied 11 bits when a configurable resource range is not previously agreed.
Further, the above resource range available for configuration can be previously sent to a user equipment through an RRC message, or preset in the user equipment in any other mode, both of which can reduce the number of bits when configuring by the MAC PDU or the PDCCH.
Embodiment 3
On the basis of Embodiment 1, the resource configuration information includes first resource configuration information and second resource configuration information;
correspondingly, before carrying the resource configuration information in the MAC PDU and sending to the user equipment, the method further includes:
sending the first resource configuration information to the user equipment in advance through a radio resource control protocol RRC message, or presetting the first resource configuration information in the user equipment;
Carrying the resource configuration information in the MAC PDU or the PDCCH signaling and sending to the user equipment, specifically includes:
carrying the second resource configuration information in the MAC PDU or the PDCCH signaling and sending to the user equipment.
This embodiment is described by taking the first resource configuration information including parameter information related to an SR resource, and the second resource configuration information including activation or deactivation information for setting availability of the SR resource as an example. The following process is also applicable to the SRS resource and the CQI resource.
Specifically, for example, the first resource configuration information includes configuration information of three parameters of a scheduling request resource period, a subframe in the scheduling request resource period allocated for the user equipment, and a PUCCH resource for bearing the scheduling request, the configuration information is carried in a previously interacted RRC message between the eNB and the UE and sent to the UE, the RRC message sent by the eNB to the UE is, for example, an RRC connection setup message or an RRC reconfiguration message sent by the eNB to the UE when the UE establishes an RRC connection with the eNB for the first time, or it can be preset in the UE according to a communication protocol between the UE and the eNB, and in an initial state, the SR resource configuration acquired by the UE is in an active state or an inactive state. Particularly, the active state is a state in which the SR resource configuration is valid, that is, the UE can acquire an SR resource using the acquired SR resource configuration, the inactive state is a state in which the SR resource configuration is invalid, in this state, the UE cannot acquire the SR resource using the acquired SR resource configuration, and in the inactive state, the acquired SR resource configuration actually does not occupy a physical layer radio resource, and is stored in the UE only as a configuration parameter.
The second resource configuration information is activation or deactivation information for setting the availability of the scheduling request resource, specifically, the activation/deactivation information can be one bit in the MAC PDU or PDCCH, or can be other indication information occupying one MAC CE field. Taking occupying one bit as an example, the bit is the activation information when it is “1”, the UE responds to the activation information and activate the SR resource configuration which is in the inactive state currently, and thus determines the SR resource according to the acquired SR resource configuration; the bit is the deactivation information when it is “0”, the UE responds to the deactivation information and deactivates the SR resource configuration which is in the activated state currently, and releases the SR resource to avoid the waste of network resources.
Besides using the second resource configuration information to modify the state of the acquired SR resource configuration, the UE also can deactivate the SR resource configuration when a time adjustment timer (TAT) expires, and thus release the SR resource. Besides, the activation information and the deactivation information also can be carried in any other signaling, for example, the activation information is carried in a random access response sent by the eNB to the UE, so as to indicate the UE to activate the acquired SR resource configuration according to the activation information, and thus acquire the SR resource.
Embodiment 4
On the basis of any of the above embodiments, the resource configuration information further includes a valid period or a number of valid times for the allocated physical layer radio resource. Specifically, for example, the SR resource configuration information further includes a valid period or a number of valid times for the SR resource; the SRS resource configuration information further includes a valid period or a number of valid times for the SRS resource; the CQI resource configuration information further includes a valid period or a number of valid times for the CQI resource.
Particularly, the valid period is a time parameter, usually an integral multiple of the resource period; the number of valid times is the number the valid resource periods, namely, to indicate the resource configuration information is invalid after how many resource periods.
Specifically, the valid period or the number of valid times can be set according to an actual network communication condition or as required, and it is used for, at the UE side, releasing the corresponding resource configuration by the UE when the valid period or the number of valid times arrives, so as to save network resources.
In addition to release the configured physical layer radio resource using the above manner, the physical layer radio resource also can be released in other manners, specifically, for example, when the TAT expires, the UE releases the SR/SRS/CQI resource configuration; or, a separate timer is configured in the UE, and the timer is for timing a duration in which the UE is in a certain state (for example, a state in which the UE does not send data), when the timer expires, the UE releases the SR/SRS/CQI resource configuration automatically.
Embodiment 5
On the basis of any of the above embodiments, before generating the resource configuration information, the method further includes:
receiving a time information report sent by the user equipment;
determining to generate the resource configuration information according to the time information report.
Specifically, due to the transmission characteristic of the separate data packet, after the UE completes the transmission of an uplink data packet, there may be no uplink data packet to be sent in a relatively long period, therefore, the UE does not need the eNB to configure the SR resource for it, and only performs uplink synchronization through a random access process, acquires relevant uplink transmission resources to complete current data packet transmission and then enters a silent period again. However, since being unable to acquire the traffic characteristics of the UE, the eNB will allocate a subsequent SR/SRS/CQI resource for the UE, or the eNB performs another SR/SRS/CQI resource configuration for the activated UE which has acquired the SR/SRS/CQI resource configuration. It can be seen that, such configuration process is obviously redundant, and wastes system resources.
Therefore, in order to further use the system resource more efficiently, the UE can be enabled to report a time information report in the process of random access or uplink data transmission, so as to provide a reference for whether the eNB should configure a physical layer radio resource. For example, the UE reports a prediction of data arrival, for providing a reference for whether the eNB should configure a SR resource. Specific examples are as follows:
Step 1, A UE in an out of synchronization state in uplink or in an RRC idle state, which needs to perform uplink data transmission, initiates a random access process, and requests to acquire uplink synchronization and an uplink transmission resource. Moreover, the UE acquires an arrival time of a next uplink data packet from its application layer, and reports the time information to the eNB, specifically, the time information report can be carried in an MAC CE of an MAC PDU to be sent; the MAC CE can be an existing MAC CE, by adding a new field to indicate the time information report, or by using a reserved field therein to indicate the time information report; or can be a newly-designed MAC CE for carrying the time information report.
Step 2, When receiving the time information report sent by the UE, the eNB determines whether to configure/activate SR information for the UE with reference to the information. Specifically, if a time value sent by the UE is greater than or equal to a timing advance timer (TA Timer), then there is no need to configure/activate the SR information for the UE; while if the time value sent by the UE is less than the TA timer, then there is a need to configure/activate the SR information for it.
The processing manner for the SRS/CQI resource configuration is similar to the SR resource configuration information, and no details will be given here.
Embodiment 6
The method for configuring resources in this embodiment is performed by the UE.
