Abstract
A method of scheduling uplink channel of a mobile station (MS) that is in soft handover in a wireless mobile communication system is disclosed. More specifically, the MS receives a plurality of scheduling commands from a non-serving cell and determines whether a specified condition is satisfied from the received scheduling commands. Thereafter, the MS adjusts a maximum transmission power when the specified condition is satisfied.
Description
Technical field
The present invention relates to field of mobile wireless communication, and more particularly, relate to the method for the uplink channel of scheduled mobile terminals when soft handover.Though the present invention is applicable to wide range of application, it is specially adapted to prevent by the caused reciprocal transition effects of the dispatching command that conflicts between Serving cell and non-service cell.
Background technology
In recent years, in mobile radio system, having the more increase of the needs of large-capacity data with higher speed transmission.In order to adapt to such increase in demand, exist and the increase that is used at the relevant argumentation number of the variety of processes of the transmission of the uplink direction from subscriber equipment (UE) (being also referred to as mobile radio station (MS)) to Node B (being also referred to as base station (BS)) high-speed data packets.
As an example of the variety of processes of just in third generation partner program Wideband Code Division Multiple Access (WCDMA) (3GPP WCDMA), discussing, a kind of up-link (E-DCH) of enhancing has been proposed.E-DCH is the transmission channel corresponding to high-speed downlink shared channel (HS-DSCH).In addition, E-DCH can be in response to the needs to the high-speed down link transmission.In addition, E-DCH can be used for by merging, such as, the scheme of Node B uplink packet scheduling strengthens efficient to the up-link (DCH) of existing 3GPP WCDMA and the mixed automatic retransmission request (HARQ) of physical layer.
At length, the HARQ scheme is included in the more high-rise retransmit operation of execution in the physical layer.In operation, the HARQ scheme combines automatic repetitive requests (ARQ) agreement with forward error correction (FEC) scheme.That is to say, keep (not abandoning) to produce wrong packet, after the packet that is combined in repeating transmission, transmit then.The HARQ scheme can be improved system throughput by the ARQ that enhancing has the error correcting capability of FEC.In the HARQ scheme, use HARQ successfully receiving uplink transfer of data represents by confirming (ACK) signal or non-affirmation (NACK).More particularly, if the packet that transmits is successfully received, MS transmits ack signal and gives Node B.On the contrary, if unsuccessful transmission, MS transmits the NACK signal and gives Node B.
Traditionally, radio network controller (RNC) control noise occurs.But in the scheduling of BS control, BS control noise occurs, rather than RNC, so that improve uplink transmission capacity.The purpose and the basic principle that are used for the scheduling of BS control are that BS can more quickly respond to the noise appearance than RNC.Therefore, can more effectively manage noise and occur, and therefore improve uplink transmission capacity.
When MS was in soft handover, the sub-district in active set can be divided into two types.According to first type, the sub-district is called as Serving cell.This Serving cell has scheduling entity.According to second type, the sub-district is called as non-service cell, and it lacks scheduling entity.
With reference to first type, the BS in Serving cell (being also referred to as serving BS broadcasts) transmits dispatching command and gives MS.This dispatching command can be by two type definitions.First type refers to absolute permission (AG), and it provides maximum transmission power (perhaps speed), and MS can send transmission by this maximum transmission power (or speed).Second type refers to relative grant (RG), and it provides the variation with respect to the power of current through-put power (perhaps speed) (perhaps speed) aspect.
In operation, RG can be transmitted by all serving BSs.But RG can be transmitted selectively or do not transmitted by the state of serving BS based on MS.In more detail, the RG of serving BS broadcasts is by " on/down " order expression.Here, " on " order refers to the amount that improves the through-put power appointment, and the D score order refers to the amount that reduces the through-put power appointment.
During soft handover, can influence the interference level of non-service cell from the signal of MS transmission by MS.Here because MS when soft handover be energetically with all cell communications in active set, occur disturbing.Influence system works if the traffic load in non-service cell increases, non-service cell can when handover, transmit dispatching command (, RG) to MS.In other words, non-service cell can transmit the MS that is used to belong to the serving BS broadcasts sub-district scheduling operation dispatching command (that is, RG).
In addition, non-service cell transmits the RG of two types, that is, and and D score order and discontinuous transmission (DTX) order.As discussed above, the D score order is used to reduce the amount of through-put power appointment.Here, be used to transmit among the pattern of RG if serving BS broadcasts is in, MS reduces the amount of maximum transmission power appointment according to the D score order that receives.But if serving BS broadcasts is among the pattern that can not transmit RG, MS reduces the amount of maximum transmission power appointment from the maximum transmission power that before receives via RG.By means of such order, can control the interference level among the sub-district that is in non-service cell.
The traffic control that is in the MS among the soft handover according to prior art has following problem.Adjust downwards after the maximum transmission power according to the RG (for example, the D score order) from non-service cell at MS, this serving BS broadcasts can transmit its RG (that is, " on " order).Reason to this is that serving BS broadcasts can determine that the transmission power level of adjusting maximum transmission power downwards is lower than the through-put power of being expected by MS.Under these circumstances, as illustrated in fig. 1, non-service cell transmits dispatching command with reduction maximum transmission power speed, and serving BS broadcasts transmits dispatching command to improve maximum transmission power.Therefore, two dispatching commands that form contrast are transmitted to MS and cause reciprocal transition effects.That is to say that from non-service cell with from the order of serving BS broadcasts receiving scheduling, it adjusts maximum transmission power to MS at every turn.Therefore, for MS, keep stable through-put power to be difficult to.
Secondly, when MS is in handover, very high for the error rate from the MS of non-service cell reception RG order.Thereby this communication system efficiency may incur loss.But prior art does not have the solution that above problem is responded.
Summary of the invention
In view of the above, the present invention proposes a kind of in mobile radio communications system the method for scheduling uplink channel during soft handover, it has been eliminated basically because the restriction of prior art and one or more problems that shortcoming causes.

Embodiment
To at length be introduced the preferred embodiments of the present invention now, the accompanying drawing illustrated that its example is being followed.As possible, run through the identical reference number of this accompanying drawing and will be used to relate to identical or similar part.
Fig. 2 is the flow chart that illustrates according to one embodiment of the invention MS example of operation during soft handover, and in Fig. 2, MS receives a plurality of RG orders (S21) that transmit from non-service cell.Then, MS determines whether that the RG that receives orders the condition (S22) that satisfies appointment.If the condition of this appointment is satisfied in the RG order, so, MS adjusts maximum transmission power (S23) according to this RG order.As discussed above, transmission rate can also be used for the operation dispatching operation.
According to prior art, whenever MS when non-service cell receives the RG order, MS adjusts maximum transmission power.Therefore, adjust through-put power according to the order that is included in each RG order.In other words, by means of the different order from serving BS broadcasts and non-service cell, when it receives the RG order, MS will constantly adjust maximum transmission power.
But according to embodiments of the invention, MS receives a plurality of RG orders from non-service cell.With respect to relatively these RG orders of condition of appointment, satisfy the condition of this appointment with the RG order that determines whether to specify number.Here, this RG that specifies number order is at least two RG orders.If the condition of appointment is satisfied in this RG that specifies number order, adjust this maximum transmission power then in view of the above.
To explain the details of the condition of this appointment after a while.
For example can have from the RG order of two types of non-service cell transmission.The RG order of first type is the D score order, and its order MS reduces or reduce maximum transmission power.The RG order of second type is " maintenance " order, and itself or order MS keep current maximum transmission power, perhaps do not transmit any order or signal and give MS.Can adopt the DTX scheme to stop transmission here.Therefore, if receive " maintenance " order, so, keep current maximum transmission power by MS by MS.
As discussed above, MS determines whether that the RG that receives orders the condition that satisfies this appointment.Here, the condition of this appointment can be divided into three types.First type of the condition of this appointment (hereinafter for " condition of first appointment ") refers to and receives the RG order (N1) that specifies number (N1) continuously, its each comprise identical order (for example, D score order).Second type (being " condition of second appointment " hereinafter) refers to and receives the RG that specifies number (N2) time cycle (T1) in appointment in and order, its each comprise identical order.The 3rd type (being " condition of the 3rd appointment " hereinafter) refers to the combination of first type and second type, and can satisfy the 3rd type by any one that satisfies two types.Alternatively, can satisfy the 3rd type by any one that at first satisfies two types.
When the condition of appointment satisfied, MS adjusted maximum transmission power.That is to say, according to the condition of first appointment, when MS receives N1 RG order continuously, each order comprises and reduces maximum transmission power (promptly from non-service cell, the D score order) order, so, MS adjusts downwards or reduces maximum transmission power.For example, when MS received three (3) RG order continuously, MS adjusted (for example, upwards or downwards) maximum transmission power.
According to the condition of second appointment, when MS received N2 RG order during T1 when, each order comprised the identical order that reduces maximum transmission power from non-service cell, and so, MS reduces maximum transmission power.For example, when MS received three (3) RG order during T1 when, MS adjusted (for example, upwards or downwards) maximum transmission power.Need during T1, not receive N2 RG order continuously here.But, can receive N1 RG order continuously.That is to say that before the T1 expiration, when MS received N2 the RG order that comprises identical D score order, preferably, MS adjusted maximum transmission power in view of the above.
Alternatively, order when MS receives N1 RG continuously during T1, when perhaps N2 RG ordered, wherein each RG order comprised the current through-put power of maintenance (promptly, " maintenance " order) identical order, MS need not to carry out any adjustment ground maintenance maximum transmission power so.In above description, the value of N1 and N2 can be same or different.
When adjusting maximum transmission power (perhaps speed) according to RG order, maximum transmission power is perhaps differently given the amount of appointment by with the increment adjustment.In other words and since RG order can only order MS or increase (for example, " and on " order), perhaps reduce (for example, the D score order), perhaps keep (for example, " maintenances " orders) through-put power, maximum transmission power is increased or reduces the amount of appointment.Here, the amount of this appointment can via the signaling of coming automatic network by MS when the call setup, perhaps after call setup, receive.Alternatively, the amount of this appointment can be a predetermined fixed value between MS and network.
Preferably, if there are at least two non-service cells, MS will handle the RG order that is used for each non-service cell independently.That is to say that MS will determine to order from the RG that first non-service cell transmits with respect to the condition of this appointment.Simultaneously, MS will determine the RG order that the condition with respect to the appointment of first non-service cell transmits from second non-service cell independently.
As discussed above, on the contrary, such as, from the D score order of non-service cell and from serving BS broadcasts " on " order of order can cause and reciprocal transition effects occurs.Therefore, owing to the big fluctuation that (RoT) causes appears in the heat on up link, influence system effectiveness unfriendly.
More than the embodiment of Xie Shiing discusses a kind of mode of resisting reciprocal transition effects by execution RG order when satisfying the condition of appointment.What below discuss is additional embodiments, calculates reciprocal transition effects by it.
Fig. 3 is that illustrating of a demonstration do not have the schematic diagram from the signal transmission of non-service cell during the time cycle of appointment.More particularly, after maximum transmission power was reduced, this non-service cell did not transmit any RG order for the time cycle of appointment.The time cycle of this appointment can be marked as T
KeepPerhaps T2.At T
KeepPerhaps after the T2 expiration, can increase maximum transmission power owing to the RG that receives from serving BS broadcasts orders.At T
KeepPerhaps during the T2, MS keeps the maximum transmission power of adjustment.
In order to make MS at T
KeepPerhaps keep maximum transmission power (perhaps speed) during the T2, the RG order that transmits from non-service cell can comprise additional conditions (for example, subcommand).This condition or subcommand can be to be failure to actuate for MS, and the perhaps instruction that keeps maximum transmission power for period (T2) of appointment is as in Fig. 4 illustrated.That is to say that after adjusting maximum transmission power according to the instruction in the RG order, instruct MS is failure to actuate in this instruction, perhaps adjusts the maximum transmission power of this adjustment for the period (T2) of appointment.In Fig. 4, in case satisfy the condition (that is, receiving N1 number purpose RG order continuously) of first appointment, after MS reduces maximum transmission power from non-service cell, do not consider during T2 the order that receives from serving BS broadcasts, the maximum transmission power that MS keeps down and adjusts for T2.After the T2 expiration, MS can carry out the instruction from serving BS broadcasts then, and in this example, this instruction will increase maximum transmission power.
With identical train of thought, in Fig. 5, in case the condition of satisfied second appointment (promptly, during T1, receive N1 number purpose RG order continuously) from non-service cell, after MS reduces maximum transmission power, do not consider during T2 the order that receives from serving BS broadcasts, the maximum transmission power that MS keeps down and adjusts for T2.As in Fig. 4, this RG order comprises condition or the subcommand that keeps the maximum transmission power of adjustment for T2.After the T2 expiration, MS can carry out the instruction from serving BS broadcasts then, and in this example, this instruction will increase maximum transmission power.
In Figure 4 and 5, though serving BS broadcasts transmit during the T2 " on " order, this MS keeps the maximum transmission power adjusted for T2.But, when it is that this situation can change when transmitting the non-service cell of RG order.
In Fig. 6, with reference to figure 4, after MS adjusted maximum transmission power, MS received the D score order that specifies number (N3) from non-service cell continuously during T2, thereby satisfied the condition of first appointment once more.When satisfying the condition of first appointment during T2 when, MS carries out the instruction of RG order, even and not expiration of T2, adjust maximum transmission power in view of the above.After this, the T2 that resets, and restart the T2 timer.If non-service cell continues to transmit the RG order, and satisfy the condition of first appointment, the processing procedure of the maximum transmission power that this is adjusted can be repeated.But if T2 is unbroken by non-service cell, so, after the T2 expiration, MS can restart normal running, such as the order of carrying out the maximum transmission power that increases serving BS broadcasts.
Similarly, in Fig. 7, with reference to figure 5, after MS adjusted maximum transmission power, MS received the D score order that specifies number (N4) from non-service cell during T2, thereby satisfied the condition of second appointment once more.Therefore, when satisfying the condition of second appointment, MS carries out the instruction of RG order, even and not expiration of T2, adjust maximum transmission power in view of the above.After this, the T2 that resets, and restart the T2 timer.But if T2 is not interrupted by non-service cell, so, after the T2 expiration, MS can restart normal running, such as the instruction of carrying out the maximum transmission power that increases serving BS broadcasts.As mentioned above, this MS can use through-put power or transmission rate.
At above number about the RG order, that is, in the example of N1-N4, the value of N1, N2, N3 and N4 can be same or different.That is to say that for example, because Fig. 6 and 7 appears at after the condition that satisfies first and second appointments respectively, N1 can be identical with N3, N2 can be identical with N4.Simultaneously, these values can be different, and with irrelevant each other.
In addition, can realize any combination of above example or embodiment (Fig. 4-7).For example, in case satisfy the condition of first appointment, after reducing maximum transmission power, if MS receives N4 number purpose RG order (for example, the D score order) from non-service cell during T2, this maximum transmission power reduces, and the T2 timer that resets.
Alternatively, at T
KeepThe maximum transmission power that perhaps keeps adjustment during the T2, as described in Figure 3, non-service cell can transmit the RG order in the period of appointment, as shown in Figure 8.Here, this RG order can comprise the instruction that keeps maximum transmission power (that is " maintenance " order).Can change the period of this appointment based on " maintenance " order.In other words, when receiving " maintenance " order, MS can keep maximum transmission power.Therefore,, determine the maintained duration of maximum transmitted from the number of " maintenance " order of non-service cell reception here by MS.
If determine the maximum transmission power of MS according to the method for above argumentation, MS determines that actual through-put power is no more than definite through-put power, wherein transmits packet via the up-link (E-DCH) that strengthens by this actual through-put power in the transmission range that allows.In addition, in the time of among serving BS broadcasts is in RG command transfer pattern or non-transmission mode, MS can be from the order of serving BS broadcasts receiving scheduling.
Apparent for those skilled in the art, do not break away from spirit of the present invention or scope, can carry out various modifications and variations in the present invention.Therefore, this invention is intended to cover it improvement of the present invention and variation that is provided within appended claim and its equivalent scope is provided.
