Description
Technical Field
The invention relates to a scheduling measurement technology, in particular to a method and a system for realizing scheduling measurement in a time slot 0 based on High Speed Downlink Packet Access (HSDPA) resource allocation.
Background
To meet the increasing demand of users for high speed packet data access services, 3GPP Rel5 introduced HSDPA technology. Wherein Adaptive Modulation Coding (AMC) or HARQ technology is employed for implementing high order modulation; and a medium access control layer HSDPA (MAC-hs) entity is added on the base station side for realizing the fast scheduling of data. By adopting HSDPA key technologies such as AMC/HARQ and MAC-hs, the method not only can obtain higher user peak rate and cell data throughput rate, but also reduces data transmission delay.
After introducing HSDPA technology, the channels introduced accordingly include: a High Speed Downlink Shared Channel (HS-DSCH); a High Speed Physical Downlink Shared Channel (HS-PDSCH); a Shared Control Channel for HS-DSCH (HS-SCCH); shared Information Channel (HS-SICH).
The HS-DSCH is used as a transmission channel of the HSDPA, is used for bearing downlink HSDPA data, completes the transmission of high-speed downlink data, and is mapped to the HS-PDSCH. A plurality of terminals (UEs) share the HS-DSCH through time division multiplexing and code division multiplexing. The HS-DSCH employs link adaptation techniques and is always accompanied by a Dedicated Physical Channel (DPCH) and one or more HS-SCCHs. The other channels, except the HS-DSCH, are physical channels. The uplink HS-SICH and the downlink HS-SCCH are shared control channels of two physical layers related to the HS-DSCH, and closed-loop control of data transmission is completed through the cooperation of the two control channels. Here, HS-SICH may also be referred to as HSDPA uplink feedback channel. The HS-SCCH may also be referred to as an HSDPA downlink scheduling control channel.
The HS-SCCH is a downlink control channel of HSDPA, occupies two code channels with a downlink Spreading Factor (SF) of 16, adopts a fixed Quadrature Phase Shift Keying (QPSK) modulation mode and is used for bearing control information of the HS-DSCH. For each Transmission Time Interval (TTI) of the HS-DSCH, the HS-SCCH is used for carrying HS-DSCH related downlink control information carried by the UE.
Table 1 below shows information carried by the HS-SCCH channel, and as shown in table 1, the control information carried by the HS-SCCH channel includes Transport Format Resource Indication (TFRI) information, HARQ information, H-RNTI information, and uplink synchronization control word (SS) information/uplink power control word (TPC) information. Wherein, the TFRI information is used to indicate the following transport format of the HS-DSCH, including the slot code channel allocation information, modulation scheme, and Transport Block Size (TBS) information of the HS-DSCH. The HARQ information includes a HARQ process identification number, an incremental redundancy version number, a new data indication, and a HCSN sequence for HS-SCCH channel quality estimation. Here, different incremental redundancy version numbers determine different rate matching schemes, and different 16-QAM bit reordering schemes. The H-RNTI information is used to distinguish different UEs on the shared channel.
TABLE 1
The HS-SICH is an uplink control channel of HSDPA, occupies a code channel with uplink SF of 16, adopts a fixed QPSK modulation mode, and is used for responding to a data block on the received HS-DSCH by an ACK/NACK message and feeding back quality information of a downlink, namely HS-DSCH Channel Quality Indication (CQI) so as to better help a base station Node B to carry out scheduling. In addition, the HS-SICH also carries uplink power control word (TPC) information of a downlink.
And the timing relation of the HSDPA shared channel and the control process of the HS-SCCH are specifically as follows: after the downlink data arrives, the Node B schedules and firstly sends downlink control information on the HS-SCCH; after receiving the HS-SCCH, the UE reserves time to decode the control information on the control channel; then, monitoring a data channel according to the control information, and correctly receiving downlink HSDPA data mapped on an HS-PDSCH by an HS-DSCH; and finally, feeding back the ACK/NACK message to the NodeB by using a corresponding HS-SICH channel.
Fig. 1 is a schematic diagram illustrating a typical resource allocation manner in a conventional Time Division Duplex (TDD) system after HSDPA technology and High Speed Uplink Packet Access (HSUPA) technology are introduced successively in the TDD system. In fig. 1, the abscissa represents time, the time slots 0 to 6 are respectively represented by TS0 to TS1, and the ordinate represents code channels occupied by resources.
Wherein, the configuration on the time slot 0 is as follows: two main common control physical channels (P-CCPCH) fixedly occupy a code channel 1 and a code channel 2 of a time slot 0, wherein the SF is 16; a Fast Physical Access Channel (FPACH) occupies a code channel resource with SF 16; the Paging Indicator Channel (PICH) and the secondary common control channel (S-CCPCH) are time division multiplexed with a plurality of code channels with SF 16.
In addition to slot 0, the configuration on the other slots is: configuring an uplink control channel, such as a Physical Random Access Channel (PRACH) and a plurality of HS-SICHs, in the time slot 1; configuring an uplink enhanced physical channel (E-PUCH) in the time slot 2; configuring HS-DSCH from time slot 3 to time slot 5; the time slot 6 configures downlink control channels such as an HS-SCCH, a resource grant channel (E-AGCH), and a hybrid automatic repeat request feedback channel (E-HICH). Here, the E-AGCH is also referred to as HSUPA scheduling control channel and the E-HICH is also referred to as HSUPA feedback channel.
Here, it should be noted that, according to the configuration mode of typical resources in the existing TDD system shown in fig. 1, it can be known by analyzing the relationship between the resource configuration of the timeslot 0 and the measurement: if the UE is in a radio resource control (CELL-FACH) state of continuously monitoring a forward access channel, the UE needs to continuously receive an S-CCPCH, which inevitably affects inter-frequency and inter-system measurements performed on the UE. That is, when the terminal continuously monitors the S-CCPCH, the terminal cannot simultaneously change its receiver frequency, measure neighboring cell signals of other frequencies or neighboring cell signals of other systems, and thus cannot perform inter-frequency and inter-system measurements. At present, the corresponding solutions are: the PICH and the S-CCPCH are made to time-division multiplex the same physical resource, and the different frequency and different system measurement is executed at the time of configuring the PICH resource.
In addition, in the existing TDD system, the conventional downlink common channel generally refers to a Forward Access Channel (FACH) and a Paging Channel (PCH), and the FACH and the PCH are multiplexed on the S-CCPCH together. Because the existing TDD system is a code channel limited system, the system can not configure too many resources for the S-CCPCH, so that the transmission data rate on the FACH and the PCH is low and the time delay is large. In order to solve the problem, in an enhanced level system of HSDPA and HSUPA, such as an HSPA + system, data mapped to FACH and PCH are mapped to HSDPA channels for transmission, that is, FACH and PCH channels of the existing TDD system are enhanced by techniques such as high-order modulation applied to the HSDPA channels.
However, although the data rate on the conventional downlink common channel is increased by transmitting the data on the conventional downlink common channel through the HSDPA channel, the problem of load imbalance between channels is also caused. In order to achieve load balance between the enhanced channels, resources of the conventional downlink common channel need to be transferred to HSDPA resources. Because the conventional downlink common channel is generally configured in the time slot 0, the HSDPA resource needs to be configured in the time slot 0, so that the load balance between the enhanced channels can be achieved.
The prior art has the following defects: the HSDPA resources are configured to slot 0, and then the HSDPA channels configured to slot 0 may be HS-SCCH and HS-PDSCH. For HS-SCCH, since the UE needs to continuously monitor and receive HS-SCCH and decode it, the HS-SCCH is configured at time slot 0, and at the time of receiving HS-SCCH, the UE cannot simultaneously change its own receiver frequency, measure the neighboring cell signals of other frequencies or the neighboring cell signals of other systems, and thus cannot perform inter-frequency and inter-system measurements. For HS-PDSCH, the HS-PDSCH is configured in a time slot 0, after a scheduling command on the HS-SCCH is received, the HS-PDSCH channel of the time slot 0 needs to be monitored continuously, and UE cannot perform pilot frequency and inter-system measurement. Briefly, the prior art has the following disadvantages: after the HSDPA resource is configured to the timeslot 0, there is a problem that the UE cannot perform inter-frequency and inter-system measurement, and at present, no effective solution is provided for the problem.

Detailed Description
The core idea of the invention is as follows: according to different configuration conditions of the current HSDPA resources, corresponding configuration information is sent through a high-level signaling process, and scheduling measurement is executed by adopting a corresponding scheduling measurement mode, so that the problem that different frequency and different system measurement cannot be executed under the condition that the HSDPA resources are configured in a time slot 0 is solved. The adopted scheduling measurement mode is a mode of configuring measurement opportunity for high-level signaling, a mode of configuring HSDPA resources in time division of the high-level signaling and a scheduling measurement mode of a base station scheduler.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings by way of examples.
A method of performing scheduling measurements, the method comprising the steps of: and according to the configuration condition of the current HSDPA resource, sending corresponding configuration information through a high-level signaling process, and executing scheduling measurement by adopting a corresponding scheduling measurement mode.
Here, according to different configuration situations of the current HSDPA resource, correspondingly, different scheduling measurement modes are adopted according to different configuration information to achieve scheduling measurement.
The first embodiment is as follows: the current HSDPA resource configuration situation is: continuously configuring an HSDPA downlink scheduling control channel (HS-SCCH) and an HS-PDSCH (high speed physical downlink shared channel) in a time slot 0, wherein the configuration information comprises a measurement period and a measurement duration correspondingly; the scheduling measurement mode is a mode of configuring a measurement opportunity for a high-level signaling.
As shown in fig. 3, the method flow of this embodiment includes the following steps:
Here, the measurement period and the measurement duration are parameters for calculating the measurement opportunity. Since the number of neighboring cells to be measured by UEs in the same cell is approximately the same as the number of frequency points, the measurement periods of different UEs in the same cell can be set to be the same. In addition, only a certain measurement offset value offset needs to be set between different UE measurement occasions, so that the problem of HSDPA resource waste on the time slot 0 due to overlapping of multiple UE measurement occasions can be avoided. The configuration relationship between the measurement period and the measurement occasion can be intuitively obtained from fig. 2, where M represents the measurement period of UE1 and UE2, N1 represents the measurement occasion of UE1, N2 represents the measurement occasion of UE2, and offset represents the measurement offset value between UE1 and UE 2.
Here, the synchronization of the measurement occasion between the Node B and the UE is ensured through a higher layer signaling procedure, and the adopted way is to associate the measurement period and the measurement duration with the system subframe number.
Here, the measurement timing is calculated by: { (sub-SFN mod M) + offset, (sub-SFNmod M) + offset + N }, where N ═ M.
Wherein M is a measurement period; n is the duration of the measurement; offset is the measured offset value; the sub-SFN is the system subframe number. And (sub-SFN mod M) + offset is used to calculate the starting point of the measurement occasion; (sub-SFN mod M) + offset + N is used to calculate the end point of the measurement occasion.
The second embodiment is as follows: the current HSDPA resource configuration situation is: discontinuously configuring HS-SCCH and HS-PDSCH on the time slot 0, wherein the configuration information is the configuration proportion of HSDPA resources on the time slot 0 correspondingly; the scheduling measurement mode is a mode of allocating HSDPA resources in time division by high-level signaling.
Here, referring to an implementation scheme of UE measurement in a CELL-FACH state in an existing TDD system, since the PICH and the S-CCPCH are time-division multiplexed on the same physical resource, the UE can perform inter-frequency and inter-system measurement at the time of resource configuration of the PICH. Then, after the HSDPA resource is configured in the timeslot 0, the measurement problem may be solved by configuring the HSDPA resource in a time division manner.
As shown in fig. 4, the method flow of this embodiment includes the following steps:
Here, the information required by the measurement frequency may be the number of measurement samples reported in a required unit time.
Here, the time-division configured HSDPA resource may time-division multiplex the same code channel resource for the PICH and the HSDPA resource.
The third embodiment is as follows: the current HSDPA resource configuration situation is: configuring HS-PDSCH in time slot 0, wherein the configuration information comprises a measurement period and a measurement duration correspondingly; the scheduling measurement mode is a base station scheduler scheduling measurement mode.
As shown in fig. 5, the method flow of this embodiment includes the following steps:
Here, the measurement period may be set to M, and the measurement duration may be set to N, so that within the measurement period M, the base station scheduler schedules the UE to perform N measurements, where N also represents the number of measurements.
Here, the timer or counter is a timer/counter in which HSDPA resources on slot 0 are continuously scheduled. Taking the base station scheduler timer as an example, it is determined whether the UE measurement opportunity arrives, that is, whether the time currently set by the timer is greater than or equal to the measurement interval.
Wherein the measurement interval is a measurement interval of a base station scheduler. The calculation method of the measurement interval can be obtained by adopting a method that N times of measurement are uniformly distributed in the measurement period M. Specifically, the adopted calculation method is as follows:
wherein M is a measurement period; n is the duration of the measurement, which is also understood to be the number of measurements.
Here, the measurement time is the measurement time at which the measurement opportunity of the UE satisfying the measurement opportunity exists. The NodeB is at the measurement instant of the UE.
And step 306, the base station scheduler sends the HS-SCCH, and carries the scheduling measurement information through the HS-SCCH.
And 307, the UE decodes the received HS-SCCH and acquires scheduling measurement information.
The scheduling measurement information in step 306 is expressed in the following ways.
The first scheme is a scheme in which scheduling control information using HS-SCCH does not include information on scheduling of HSDPA resources in the UE slot 0. This approach is an implicit approach.
Then, the UE decodes the received HS-SCCH, and does not decode the scheduling measurement information belonging to the UE, or decodes that the scheduling measurement information belonging to the UE does not include the HSDPA resource on slot 0, and then the UE may perform measurement at the next slot 0. That is, it is equivalent to notifying the UE of the measurement occasion by means of such implicit signaling.
In the second mode, the mode of using a special form of information bits in the HS-SCCH scheduling control information represents the scheduling measurement information.
As shown in table 1, as can be known from information carried by the HS-SCCH in the current HS-SCCH channel structure, the Code channel resource occupied by the HSDPA resource is generally indicated by the 4-bit Stop Code and 4-bit Start Code resource indication information. Normally, the Stop Code needs to be equal to or greater than the Start Code. In particular, for Stop Code 0000 and Start Code 1111, SF 1 is indicated; while the remaining special forms of Start Code being greater than Stop Code are not defined. Therefore, the invention proposes to use a special form of the HS-SCCH that the Start Code is greater than or equal to the Stop Code to represent the scheduling measurement information.
For example, Stop Code 0000 and Start Code 0000 may be used to indicate that the measurement is performed at the next consecutive time slot 0; using Stop Code 0000 and StartCode 0001 indicates that the measurement is performed at the next two consecutive time slot 0 times.
And in the third mode, the scheduling measurement information is expressed by using a mode of expanding the HS-SCCH scheduling control information.
For example, the scheduling measurement information may be represented by adding n bits to the HS-SCCH scheduling control information. Where n is equal to or greater than 0. In short, only 1 bit of information may be added to the scheduling control information for representing the scheduling measurement information. Here, the bit information position of 1 indicates that the measurement is performed in the next slot 0, and the bit information position of 0 indicates that the normal scheduling process is performed in the next slot 0.
And a fourth mode, configuring and determining a mode for scheduling the measurement information by high-level signaling.
For example, when a radio link is established, a binding relationship between scheduling measurement information and an HS-SCCH is configured through a high-level signaling process, and when the UE receives scheduling control information belonging to the UE from the HS-SCCH in the binding relationship, the UE determines that a measurement time at which a measurement opportunity is located arrives, and then the UE performs measurement at the next time slot 0.
A system for implementing scheduling measurements, the system comprising: the system comprises a network side configuration unit, a network side sending unit, a base station side scheduling measurement unit and a terminal side scheduling measurement unit.
The network side configuration unit is used for setting corresponding configuration information according to the configuration condition of the current HSDPA resource and sending the configuration information to the network side sending unit. And the network side sending unit is used for receiving and sending the configuration information. And the base station side scheduling measurement unit is used for receiving the configuration information and executing scheduling measurement by adopting a corresponding scheduling measurement mode. And the terminal side scheduling measurement unit is used for receiving the configuration information and executing scheduling measurement by adopting a corresponding scheduling measurement mode.
Here, the system of the present invention has three implementation schemes, and the first implementation scheme is: in the system, the network side configuration unit is further configured to set configuration information including a measurement period and a measurement duration and a method for calculating a measurement timing according to information required for measurement frequency, and send the configuration information to the base station side scheduling measurement unit and the terminal side scheduling measurement unit via the network side transmission unit.
The system further comprises a judging unit for judging whether the measurement opportunity of the UE arrives. After the judgment unit learns that the measurement opportunity arrives, the base station side scheduling measurement unit is further used for scheduling other UEs by using the HSDPA resources on the time slot 0 at the measurement moment of the measurement opportunity of the UE; and the terminal side scheduling measurement unit is used for executing measurement at the measurement time of the UE measurement opportunity.
The second implementation scheme is as follows: in the system, the network side configuration unit is further configured to set configuration information as a configuration proportion of HSDPA resources according to information required for measurement frequency and information required for resources by channel capacity, and send the configuration information to the base station side scheduling measurement unit and the terminal side scheduling measurement unit via the network side transmission unit.
The system also comprises a judging unit used for judging whether the non-HSDPA resource time arrives. After the judging unit learns that the non-HSDPA resource time arrives, the base station side scheduling measuring unit is further used for sending data on other channels at the non-HSDPA resource time; the terminal side scheduling measurement unit is further configured to perform measurement at the non-HSDPA resource time.

And the network side configuration unit is further used for setting configuration information including a measurement period and a measurement duration according to the information of the measurement frequency requirement, and transmitting the configuration information to the base station scheduler through the network side transmitting unit.
