Description
(1) technical field
The present invention relates to a kind ofly in wireless communication system, particularly in mobile radio communications system, be used for the method for transmission signals between a base station and user terminal.
(2) background technology
In wireless communication system, signal is by a so-called wave point or air interface and exchange between wireless terminal and base station.In general wireless terminal can be that (be subscriber equipment, UE), and base station (being NB, Node B) is those access stations that link to each other with terrestrial communications network to that move or fixing user terminal.Known wireless communication system for example can be a second generation digital mobile radio communication system, for example a kind of its data transmission rate can reach 100k bit/s, based on the Global Link mobile communication system (GSM) of tdma (TDMA), also can be third generation data mobile communication system, for example a kind of universal mobile telecommunications system (UMTS) that can reach code division multiple access (CDM) technology of 2M bit/s based on data transmission rate.
International Telecommunication Union has issued a plurality of radio interface standards that are used for standard third generation mobile wireless network.Some standards wherein comprise by two standards of 3G (Third Generation) Moblie partner plan (3GPP) called after UTRA-FDD and UTRA-TDD, reach a standard of being planned 2 (3GPP2) called after CDMA2000 by the 3G (Third Generation) Moblie partner.The UTRA-TDD standard is divided into the scheme (LCR) of the low spreading rate of the scheme (HCR) of a high spreading rate of so-called 3.84Mcps and a 1.28Mcps again, and these two schemes all are based on standardized universal mobile communication system (UMTS) network architecture again.The air interface configuration of LCR scheme is close to identical with the TD-SCDMA standard again.Described TD-SCDMA standard is based on GSM (the being also referred to as TSM) network architecture, and is decided to be standard in China by the standardization effort committee of China's Telecommunication (CCSA).
TDD-LCR and TD-SCDMA standard are all based on time division duplex technology (TDD), be each time frame (timeframe, tf) constitute by two class time slots, one class is time slot (TS0, DwPTS TS4......TS6), is used to represent from a base station to the sub-district (C1 that this base station covered, C2, C3) in the downlink transmission mode of one or more user terminals (UE); Another kind of is that (UpPTS TS1......TS3), represents the uplink signal transmissions from described user terminal to described base station to time slot.This two classes time slot as shown in Figure 1.Uplink and downlink timeslot can be disposed by network agile among the TS1......TS6, but has an ascending time slot at least, and has a descending time slot at least.
In TDD-LCR and TD-SCDMA standard, first time slot (TS0) in time frame is used for the General System information of transmitting broadcasting channel (BCCH) by the base station, used through-put power is higher, so that this signal can arrive in the sub-district (C) that described base station covered user terminal farthest.In general, the sub-district of a base station is limited by the scope of corresponding broadcast channel.Behind first time slot succeeded by a descending pilot frequency time slot (DwPTS), protection time slot (GP) and a uplink pilot time slot (UpPTS); the signal that described descending pilot frequency time slot is used for simultaneous user's terminal transmits at this time slot exactly; described protection time slot is represented one first switching point (DL/UL-SP) between downlink transmission direction and uplink direction; described uplink pilot time slot (UpPTS) is also referred to as up access slot (UATS), is used to one first access request representing that user terminal sends to described base station.Succeeded by a plurality of ascending time slots, and at second switching point (UL/DL-SP) a plurality of descending time slots afterwards, be used for data and signal transmission between base station and the user terminal behind the uplink pilot time slot.Fig. 2 shows described time slot map.
In 3GPPLCR and CCSA (standard committee of China's Telecommunication) TSM system, user terminal is carried out described uplink synchronous control (ULSC) and uplink power control (ULPC) order, these two kinds of orders are to extract from the downlink data burst of base station, and described base station is from correspondingly extracting descending power control (DLPC) order the user terminal upstream data burst.
Below, the rise time (a generation time) is defined as time interval between the transmission time that the time of reception of the upstream data burst at place, base station for example and descending ULPC order.To be defined as the time of implementation from receiving above-mentioned physical layer command to carrying out the required time interval of this order.In addition, the round-trip transmission path delay of time (round trip delay) is defined as from for example receiving a upstream data burst to a time interval the ULPC order of carrying out to produce based on this upstream data burst.
Illustrated among Fig. 3 and in the TDD system, how to have formed a described round-trip transmission example in the path delay of time.Here each needs a subframe to handle received data burst, to obtain the measurement result that is used to generate power control and/or uplink synchronous order to suppose user terminal and base station.Supposition generates command word in addition and data burst needs 2.5 time slots.Therefore, in example shown in Figure 3, round-trip transmission path delay of time is 3 subframes, i.e. 15ms.
Stipulate that in the TSM standard user terminal should be carried out these orders when receiving the next one after ULPC and the ULSC order to data burst that the base station sends; And carry out this DLPC order when conversely, the base station should send to the data burst of described user terminal at the next one after receiving DLPC order.Situation below these constraintss of defined for example may cause in the standard takes place, and user terminal can't respond mentioned order and significantly decline of performance in a subframe.If have the ability in the base station and standard allows it to respond described order in faster than the time of a subframe, then can improve systematic function.
Therefore, one object of the present invention is to provide a kind of method, can make base station and/or user terminal carry out above-mentioned work order more neatly under the prerequisite of the performance depreciation that does not make system.This purpose of the present invention is to be realized by method given in the file of the present invention, base station user terminal and wireless communication system

(5) embodiment
The basic structure schematic diagram of a mobile radio communications system (as a system based on TD-SCDMA or TDD-LCR standard) has been shown among Fig. 1.This system is made of a mobile switching centre that is connected with Public Switched Telephone Network (PSTN) (MSC, not shown) and a plurality of other mobile switching centre.A plurality of base station controller BSC 1, BSC2 link to each other with a mobile switching centre, and with other device, the wireless resource allocation that common coordination is provided by base station (BTS1...BTS3, i.e. base station transmitting-receiving station).Base station sub-system BSS1 represents the arrangement of each base station and base station controller.In the example shown in the figure, base station BTS 1 links to each other with one first base station controller BSC 1 with BTS3, base station BTS 2 links to each other with one second base station controller BSC 2 (not shown)s, and two base station controller BSC 1 link to each other with same moving exchanging center MSC again with BSC2.Base station BTS 1...BTS3 sends downstream signal to the user terminal UE that is arranged in its sub-district C1...C3 that covers (being subscriber equipment) respectively, and receives upward signal UL respectively from above-mentioned user terminal UE.Except sending to user terminal and receiving the described signal from user terminal, described base station BTS 1...BTS3 also broadcasts general system information in broadcast channel BCCH1...BCCH3.In Fig. 1, each among the base station BTS 1...BTS3 comprises an aerial array, and described each aerial array is made of a plurality of antenna elements.Each aerial array is also referred to as smart antenna, is used to that the signal that sends to each user terminal is carried out wave beam and forms (beamforming, or title pack), to reduce the interference that parallel those signals transmission that are connected to other user terminal are caused.
The structure chart of the time frame tf of defined in TDD-LCR and the TD-SCDMA standard has been shown among Fig. 2.Long for the time frame tf of 5ms comprise one long be the first time slot TS0 (1 symbol=12.5 μ s=16 chips) of 662.5 μ s, this first time slot TS0 and other time slot together are used at descending BCCH to a plurality of user terminals transmission broadcast messages that are arranged in a sub-district that is covered by this base station by a base station.After the first time slot TS0 succeeded by one long be the so-called descending pilot frequency time slot of 50 μ s, this descending pilot frequency time slot is used for sending a plurality of synchronizing sequences at down direction by the base station, these synchronizing sequences by described these user terminals be used to realize self and base station synchronously.Between first time slot of descending pilot frequency time slot and uplink, have one long be the protection time slot of 75 μ s, as one first switching point DL/UL-SP between descending and up these two transmission directions.Uplink direction first time slot is called as uplink pilot time slot UpPTS or up access slot (UATS), and length is 100 μ s, is used for sending a plurality of sequences that insert for the first time at an access procedure at random to the base station by described those user terminals.Is a plurality of ascending time slot TS1...TS3 and a plurality of descending time slot TS4...TS6 after the uplink pilot time slot, wherein the length of each time slot all is 62.5 μ s, be used to realize with user terminal between normal two-way transmission and receive relevant signal and data.The second switching point UL/DL-SP is the switching point of a so-called position changeable, and its result can change between 6 time slot TS1...TS6, and decide according to the traffic carrying capacity of two transmission directions of current uplink and downlink its position.
In TSM technical standard 05.08 as prior art, the time of carrying out a power control command is to determine like this: " when receiving a ground floor power control command, this receiving element (base station or subscriber equipment) is correspondingly adjusted the rank of (promptly by increase or reduce the decibels (Stepsize-PCdB) of power control step-size or make it to remain unchanged) through-put power in the corresponding time slot of the next frame that carries the power control command frame ".
Correspondingly, the time rule to the execution synch command is as follows in the TSM technical specification 05.10: " subscriber equipment should be carried out the simultaneous bias order that the base station sent of serving it at its following frame that carries the synchronous control command frame ".
The response time of one frame has been improved the complexity of subscriber terminal equipment.Usually, the every 5ms of user terminal (promptly in each subframe) carries out joint-detection one time.From the angle of complexity, when user terminal spent a subframe and handles received all data blocks, complexity at this moment was minimum.When this process needs to carry out more hurry up, receive disposal ability in some period and can be in idle state, make this subscriber equipment load too high, can strengthen the equipment cost of user terminal like this.
For user terminal, the worst situation is to receive at the 6th descending time slot (TS6), and sends at first ascending time slot.In this case, subscriber equipment has to react at an only time slot.For simple user terminal more, solution is to reduce the ability of the physical layer symbols that related detection device base stations detected sent, and does not for example carry out joint-detection.Fig. 4 shows the result that may occur when omitting the joint-detection step.The error rate of power control (PC) that usually, is received and uplink synchronous (ULSC) sign indicating number is about 4%.In the example shown, the error rate can highly arrive even surpass 10%.As a result, need higher transmitted powers (average power will be heightened to eliminate the influence of these error codes in the base station) and/or relatively poor uplink synchronous can take place.
Another kind of situation is to receive downstream signal and send upward signal later at 3 time slots at time slot TS0.Though the user terminal of powerful disposal ability is arranged can react to received signal in the so short time interval, but according to relevant technical standard, must the next logic subframe after receiving control command could carry out information concerning order, this means that subscriber equipment could carry out information concerning order after 5ms.Can occur long, the unnecessary round-trip transmission path delay of time like this, finally influence the performance of control algolithm.
When upward signal early time slot in a certain subframe arrive base station and downstream signal at later time slot when send the base station, same situation also occurs on the base station.This situation also can influence the operational effect of control algolithm, long, unnecessary trip path time delay occurs.
According to the present invention, can signal is transferred to the opposite end to described rise time and/or time of implementation.For example, can the rise time and the time of implementation of base station be broadcasted in the sub-district that the base station covered by broadcast channel BCCH, and also the rise time and the time of implementation of user terminal can be sent to described base station by user terminal in ability information of user terminal.
The importance in round-trip transmission path delay of time
In any control system, learn that how slave mode reacts to relevant order all is very important.Have only and use special model, just may effectively control relevant slave mode.In these important parameters very important one, described exactly slave mode is adjusted the time delay that order is occurred when reacting to relevant.In the time can not definitely learning this length of delay, system can starting oscillation.When system is driven by the improper value of an oscillatory simultaneously, can inspire a vibration frequency, the result is such as using higher transmitting power, perhaps can making the uplink synchronous algorithm can't realize required synchronous regime.
Because their timings are separately known in user terminal and base station, the opposite end also should be as can be known to the response time of physical layer command order.
These unsure states have been shown in the following form.In this example, suppose power control, the path loss constant magnitude, and a controlled step in subframe 0 has an initial error.The size in supposition round-trip transmission path delay of time subframe always in this algorithm.When round-trip transmission was a subframe path delay of time really, waving forward can take place in algorithm, but can not vibrate.
When the round-trip transmission of reality was two subframes the path delay of time, situation became like this: in subframe 0 mistake takes place, and require step-length of power control command downward modulation.In subframe 1, because mentioned order is not also carried out by a relative side, this mistake still exists.As a result, can require power control command to reduce a step-length again.Above-mentioned two orders just have been performed up to subframe 3.But, need the order of a power rise this moment because relevant controller has been carried out the order of power decreasing too much.Like this, oscillatory process can continue always.
If controller is known the opposite end and can not carry out first power control command that then it just can not send second order, because like this after a subframe, mistake will become 0.
To the bigger round-trip transmission path delay of time, result and above-mentioned phenomenon are similar.Difference only is that cycle of oscillation is longer, and oscillation amplitude is bigger.
| Subframe | 0 | ?1 | ?2 | ?3 | ?4 | ?5 | ?6 | ?7 | ?8 |
| Postpone 1 | ?1 | ?0 | ?0 | ?0 | ?0 | ?0 | ?0 | ?0 | ?0 |
| Postpone 2 | ??1 | ??1 | ??0 | ??-1 | ??-1 | ??0 | ??1 | ??1 | ??0 |
| Postpone 3 | ??1 | ??1 | ??1 | ??0 | ??-1 | ??-2 | ??-2 | ??-1 | ??0 |
| Postpone 4 | ??1 | ??1 | ??1 | ??1 | ??0 | ??-1 | ??-2 | ??-3 | ??-3 |
Table 1 when path loss be steady state value and round-trip transmission path delay of time not simultaneously, the unsteadiness that the power departure is occurred is after relevant rise time and time of implementation signal are issued, and those user terminals that disposal ability is strong and/or base station can be faster than those user terminals and/or the base station reaction of the timing scheme that adopts current standard fixed.
Main feature of the present invention is:
Send the signaling of time of implementation: know that there is very important meaning the time of implementation in base station and the user terminal to the operation of guaranteed output control and/or uplink synchronous algorithm.Adopt method of the present invention, both can make the base station know the time of implementation that user terminal is required, also can make user terminal know the time of implementation that the base station is required.
Send the signal of rise time:, also need to adopt and send identical mode of time of implementation and send the rise time for guaranteeing the execution of discontinuous transmission; Could guarantee that in this way user terminal can carry out up-to-date physical layer command conscientiously when discontinuous transmission because have only, and know definitely and when no longer continue to carry out these orders.
Provide the example of implementing the present invention program below.Other implementation of this example and the present invention program can be at 3GPP LCR, and CCSA TSM and controlling mechanism similarly realize in other telecommunication system with it.
The following message unit can be sent with the form of signaling:
The rise time of-uplink power control order
The rise time of-uplink synchronous control command
The time of implementation of-descending power control command
The rise time of-descending power control command
The time of implementation of-uplink power control order
The time of implementation of-uplink synchronous control command
The signaling scope can be from 1 time slot (being next time slot) to for example 16 time slots.Because different user terminals can have different processing speeds, the time slot of above-mentioned size can provide an enough wide dynamic range.The value coding that can will need with the binary code of for example 4 bits to transmit sends.
Described signaling information can transmit in system information or capabilities of user devices information.At receiving terminal, described information parameter is extracted by high level, and is fed to physical layer, and is used for control algolithm.This process can realize by known methods, for example power control step-size information is sent to the implementation of physical layer controlled area.
Described signal message can also continue on in the network, as used for radio network controller or base station controller Resources allocation.Under user terminal performance condition of limited, in a subframe, distribute uplink and downlink timeslot can for this user terminal with optimal time interval.
