Description
Technical field
The present invention relates to communication technical field, determine the method and the base station of UE (User Equipment, subscriber equipment) downlink member carrier monitored in the particularly a kind of asymmetric polymerization LTE system.
Background technology
In the Long Term Evolution wide-band mobile communication system, LTE-Advanced system for example, higher peak rate need be provided by bigger transmission bandwidth, satisfy user's demand, that is inclined in the current research provides more that the method for large transmission bandwidth is that a plurality of continuous or discrete existing frequency ranges are carried out polymerization.Carrier aggregation (CA, Carrier Aggregation) technology is meant in the LTE-A system in order to support wideer transmission bandwidth, the uplink and downlink bandwidth can comprise a plurality of member carriers in a sub-district, each member carrier can frequency domain continuously also can be discontinuous, for the discontinuous CA of frequency domain.For with the LTE compatibility, the maximum bandwidth of each member carrier is that maximum bandwidth is 20MHz, corresponding 110 RB (Resource Block: the granularity of carrying out resource allocation for network).
In mobile communication system, carry out transmitting uplink data and need satisfy a kind of distinctive transmission conditions, i.e. uplink synchronous.Its objective is that the upward signal that makes from the different terminals of different distance can arrive base station/relaying synchronously.Uplink synchronous can be brought a lot of benefits to system: as reducing the interference of signal between adjacent time-slots, improve systematic function, simplify the design of base station/link receiver etc.Therefore, be in the asynchronous regime terminal, before sending upstream data, needs use random access procedure is set up the uplink synchronous with network, could carry out subsequent transmission then under the method for synchronization.As shown in Figure 1, the flow chart for inserting at random in the prior art may further comprise the steps:
Step S101, terminal is selected one at random in all available Preamble (Random Access Preamble, random access leader sequence), and goes up transmission at RACH (Random Access Channel, Random Access Channel).
Step S102, the base station is detected the RACH channel, if monitor Preamble, then calculates the TA (Timing Alignment, regularly adjustment amount) of this Preamble correspondence.
Step S103, the base station sends the accidental access response to detected Preamble, comprises following information in the accidental access response: the identification information of the Preamble that is received, as numbering, transmitting time etc.; The TA of the Preamble correspondence of being received; The information of the channel resource that distributes for follow-up transmitting uplink data, when comprising resource-position frequently, MCS (modulation coding mode) etc.; The interim ID (C-RNTI) that the base station is distributed for the user.
Step S104, terminal according to the identification information of wherein Preamble, determines whether the target terminal of this accidental access response information is oneself after receiving accidental access response.If, adjust the transmission Timing Advance of upward signal according to TA information wherein.
Step S105, terminal sends upstream data, and its used ascending resource is that the base station is the resource of its distribution in step S103.At least should comprise in the upstream data that terminal sends: the identification information of terminal, as C-RNTI.
Step S106, whether the identification information of the terminal that the base station sense terminals sends in step S105 is legal, and notifies terminal by competition solution message with testing result.
After the Overall Steps of having finished above-mentioned random access procedure, transmitting uplink data just can have been carried out in terminal and base station.
But in the system that adopts asymmetric CA technology (for example: the downlink member carrier number is more than the uplink member carrier number), may there be the situation of the corresponding upstream band of a plurality of downstream bands.As shown in Figure 2, be asymmetric CA system up-downgoing member carrier corresponding relation schematic diagram in the prior art, wherein uplink member carrier f1 corresponds respectively to downlink member carrier f2 and f3.Therefore in this configuration, downlink member carrier f2 and f3 can broadcast the random access resource information that is positioned on the uplink member carrier f1.That is to say that the UE that monitors f2 or f3 might initiate to insert at random on f1, and when network was received the Preamble of UE transmission, it can't judge UE institute downlink member carrier monitored.Network is received its response to Preamble in order to ensure UE, needs to send on downlink member carrier simultaneously accidental access response, promptly simultaneously sends accidental access response on downlink member carrier f2 and f3.And before network was judged the UE downlink member carrier monitored, it all must send on two downlink member carriers to the message that UE sends simultaneously, and this will inevitably cause the wasting of resources.
The shortcoming that prior art exists is, for asymmetric CA system, before the UE downlink member carrier monitored was judged in the base station, the base station all must send on a plurality of downlink member carriers of correspondence to the message that UE sends the while, has caused the serious waste of resource.Therefore how to make the base station can determine as early as possible that the UE downlink member carrier monitored becomes the key factor that solves wasting of resources problem.

In order clearer understanding to be arranged, below will above-mentioned thought be introduced in the mode of specific embodiment to the present invention.
Embodiment one,
As shown in Figure 3, method flow diagram for definite UE downlink member carrier monitored of the embodiment of the invention one, the base station is all different for the resource block location of the ascending resource of each downlink member carrier distribution in this embodiment, and the UE downlink member carrier monitored just can be determined according to the shared resource block location of UE upstream data in the base station like this.This embodiment may further comprise the steps:
Step S301, terminal is selected one at random in all available Preamble, and sends to the base station.
Step S302, the base station is calculated the TA of this Preamble correspondence according to the Preamble that receives and is that UE distributes ascending resource according to Preamble, and send to UE by each downlink member carrier of uplink member carrier correspondence, wherein, the resource block location of the ascending resource that each downlink member carrier is indicated is all inequality, and has at least at least a portion Resource Block of the indicated ascending resource of two downlink member carriers overlapped.Concrete, carry different resource block location information in the accidental access response that the base station sends on each downlink member carrier, the resource block location information that wherein has at least the accidental access response that sends on two downlink member carriers to carry is overlapped to reduce the waste of ascending resource.For example, for the situation of corresponding two downlink member carriers of member carrier (being called first downlink member carrier and second downlink member carrier) up and down, and suppose that the upstream data that UE sends need account for 2 Resource Block, the upstream data of 3 ascending resource pieces (being respectively Resource Block 1-3) in order to carrying UE transmission distributed for UE in the base station after receiving the Preamble that UE sends like this.On first downlink member carrier, send accidental access response afterwards, this accidental access response indication UE sends upstream data on Resource Block 1-2, simultaneously send accidental access response on second downlink member carrier, this accidental access response indication UE sends upstream data on Resource Block 2-3.Need to prove in the above-mentioned example that being is that example describes with two downlink member carriers, but the foregoing description can be applicable to the downlink member carrier of greater number, and the many more utilances for ascending resource of the quantity of downlink member carrier are just high more.But, also need to prove if the quantity of downlink member carrier is more, for example 5, but the Resource Block that is not these 5 downlink member carrier correspondences must be all interconnected, only need the interconnected purpose of saving ascending resource that just can reach of Resource Block of at least two downlink member carriers, be preferably all interconnected certainly.
Step S303, UE sends upstream data according to the indication (being the resource block location of accidental access response indication) of the resource allocation message of the carrying on the descending carrier of being monitored on the Resource Block of correspondence.For example, if the UE monitoring is first downlink member carrier, then UE will send upstream data according to indication on Resource Block 1-2, if be second downlink member carrier, then UE will send upstream data according to indication on Resource Block 2-3.
Step S304 determines the UE downlink member carrier monitored according to the resource block location of upstream data correspondence.For example, if the Resource Block of upstream data correspondence is Resource Block 1-2, determine that then the UE downlink member carrier monitored is first downlink member carrier; If the Resource Block of upstream data correspondence is Resource Block 2-3, determine that then the UE downlink member carrier monitored is second downlink member carrier.
Embodiment two,
As shown in Figure 4, be the method flow diagram of definite UE downlink member carrier monitored of the embodiment of the invention two.What be different from embodiment one is that this embodiment adopts the MCS form as distinguishing condition, can make the resource block location of indicating in the accidental access response that sends in each downlink member carrier all identical, further reduces the waste to ascending resource.Certain this embodiment does not limit the resource block location of indicating in the accidental access response that sends in each downlink member carrier yet must be identical, reach this embodiment and also can be used in combination, promptly by different MCS and resource block location the descending carrier that UE monitors is distinguished simultaneously with embodiment one.Particularly, this embodiment comprises:
Step S401, terminal is selected one at random in all available Preamble, and sends to the base station.
Step S402, the base station is calculated the TA of this Preamble correspondence according to the Preamble that receives and is that UE distributes ascending resource according to Preamble, and send to UE by each downlink member carrier of uplink member carrier correspondence, wherein, the indicated MCS of each downlink member carrier is all inequality, and has at least at least a portion Resource Block of the indicated ascending resource of two downlink member carriers overlapped or this is all overlapping to reduce wastes of ascending resource.For the situation of corresponding two downlink member carriers of member carrier (being called first downlink member carrier and second downlink member carrier) up and down, the base station is when carrying out resource allocation, for each downlink member carrier distributes identical HARQ such as TBS (HybridAutomatic Repeat Request, mix automatically and retransmit), but difference is to be that each downlink member carrier specifies different MCS, different MCS in requisition for Resource Block quantity may be different.For example, 2 kinds of suitable MCS are chosen in the base station after receiving the Preamble that UE sends, if the downlink member carrier number can be chosen more MCS at most certainly.These 2 kinds of MCS quantity of corresponding resource requirement piece respectively are m and n, suppose m＞=n.Send accidental access response afterwards on first downlink member carrier, it is MCS1 that this accidental access response indication UE adjusts coded system, and the Resource Block of distribution is 1-m; Simultaneously send accidental access response on second downlink member carrier, it is MCS2 that this accidental access response indication UE adjusts coded system, and the Resource Block of distribution is 1-n.
Step S403, UE adopt corresponding MCS to send upstream data on the Resource Block of correspondence according to the indication of the resource allocation message of the carrying on the descending carrier of being monitored.For example, if what UE monitored is first downlink member carrier, then UE will the mode with MCS1 send upstream data according to indication on Resource Block 1-m, if be second downlink member carrier, then UE will the mode with MCS2 send upstream data according to indication on Resource Block 1-n.
Step S404, the UE downlink member carrier monitored is determined according to the MCS of upstream data correspondence in the base station.For example, if the MCS of upstream data correspondence is Resource Block MCS1, determine that then the UE downlink member carrier monitored is first downlink member carrier; If the MCS of upstream data correspondence is Resource Block MCS2, determine that then the UE downlink member carrier monitored is second downlink member carrier.
Embodiment three,

Step S501, terminal is selected one at random in all available Preamble, and sends to the base station.
Step S502, the base station is calculated the TA of this Preamble correspondence according to the Preamble that receives and is that UE distributes ascending resource according to Preamble, and send to UE by each downlink member carrier of uplink member carrier correspondence, different downlink member carriers distributes different physical layer ID, the HARQ message of each downlink member carrier accidental access response is identical, and the upstream data that is UE distributes identical ascending resource.Particularly, different physical layer ID for each downlink member carrier distributes identical ascending resource, but is distributed in the base station when carrying out resource allocation.
Step S503, the indicated ascending resource of the accidental access response that UE sends according to the base station sends upstream data, but can adopt different scramblers based on different physical layer ID when the UE physical layer sends upstream data.
Step S504, the scrambler that is adopted when the base station sends upstream data according to the UE physical layer is determined the UE downlink member carrier monitored.
