Description
Technical field
The present invention relates to moving communicating field, particularly, the present invention relates to a kind of computational methods and device of measuring opportunity.
Background technology
Move the developing direction that becomes modern communication technology with the broadband, 3GPP (3rd GenerationPartnership Project, third generation partner program) is devoted to LTE (Long TermEvolution, Long Term Evolution) system is as the evolution of 3G system, and target is that development 3GPP wireless access technology is towards high data rate, the low delay and the evolution of optimization packet data application direction.
In the 3GPP system, LCR TDD (Low Chip Rate Time Duplexing Division, low spreading rate time division duplex) introduced DRX mechanism under the quick access channel CELL-FACH state of enhancing sub-district, make UE pass through discontinuous reception to down channel, can periodically close receiver, reach the purpose of UE economize on electricity, the up-downgoing data that strengthen UE under the CELL-FACH state all adopt the mode of scheduling to transmit, what therefore DRX mechanism was primarily aimed at is the discontinuous reception of UE to down control channel, DRX is meant down control channel is carried out discontinuous reception that RX is meant down control channel is received continuously.
Strengthen in the DRX mechanism of CELL-FACH, defined fixing DRX Pattern, be interpreted as which UE carry out RX constantly, which carries out DRX constantly at, DRX Pattern is expressed as repetition period and repeat length, be presented as parameters such as DRX Cycle, RX Burst, as shown in Figure 1, be DRX Pattern and the diagram of measuring Pattern.
UE receives the duration that continues to down control channel RX in a DRX cycle DRX Cycle be Rx Burst, Rx Burst can be one or more radio frames, UE in DRX Cycle except that Rx Burst other time do not monitor down control channel, be that DRX receives, this situation is to repeat in the cycle with DRX Cycle, and DRX Pattern and SFN (System Frame Number, system frame number) is associated, UE calculates DRX Pattern according to identical SFN with NodeB, reach the both sides cognitive consonance and determine corresponding radio frames, computational methods are as follows:
(SFN-H-RNTI)mod(DRX_cycle)＜Rx_burst (1)
Wherein, it is the specific Offset of UE that H-RNTI can be used as, H-RNTI is RNTI (the Radio Network Temporary Identifier of UE special use, Radio Network Temporary Identifier), DRX_cycle is DRX (Discontinuous Reception, discontinuous reception) in cycle, Rx_burst is the time period of continuous transmission information in the DRX.
Strengthen the configuration of DRX parameter under the CELL-FACH state, RNC notifies NodeB by NBAP message with the DRX parameter, UE learns the DRX parameter by the system broadcasts that reads the sub-district, both use identical DRX parameter in the computational process of follow-up DRX Pattern, the value of Rx Burst is 1,2,4,8,16, the value of DRX Cycle is 4,8,16,32, and unit is radio frames (10ms), and the configuration of DRX Cycle all is 2 integral number power as can be seen.
In addition,, strengthen CELL-FACH state UE down and will carry out measurement according to existing protocol, similar with DRX Pattern, measure Pattern and can be understood as UE and need carry out constantly at which and measure action, about being calculated as follows of the SFN of UE measurement correspondence on opportunity:
SFN＝H-RNTI?mod(M_REP)+n*M_REP (2)
UE need carry out measurement in a represented radio frames of the SFN that satisfies following formula, as shown in Figure 1, wherein, the H-RNTI that adopts in H-RNTI and the DRX Pattern computational process is identical, M_REP is measurement Cycle Length on opportunity (Measurement Occasion cycle length), M_REP=2k, k is that FACH measures Cycle Length coefficient on opportunity (FACH Measurement occasion cyclelength coefficient), UE learns parameter k by reading cell system broadcasting, n=0,1,2..., the configuration of M_REP also is 2 integral number power as can be seen.
Yet, in present agreement, because the value that strengthens parameter DRX Cycle, M_REP under the CELL-FACH all is 2 integral number power, H-RNTI is identical, the Rx Burst that utilizes above-mentioned formula to calculate might coincide together with measurement constantly opportunity, as when Rx Bust=1 and the DRXCycle=M_REP, DRX Pattern overlaps fully with measuring Pattern, as shown in Figure 2.Simultaneously, strengthen CELL-FACH for LCR TDD, the scheduling process of transmitting uplink data need rely on the reported result of SNPL, and UE calculates SNPL according to the measurement result with the frequency alien frequencies, so when TS0 configurating downlink control channel, RX bumps with measurement constantly opportunity, UE can not both carry out descending continuous reception simultaneously, carry out different-frequency measure again, have influence on the result of calculation of measurement performance and the SNPL of UE.Therefore, be necessary to propose a kind of technical scheme, solve the problem that RX bumps with measurement constantly opportunity.

In order to realize the present invention's purpose, embodiments of the invention have proposed a kind of computational methods of measuring opportunity, may further comprise the steps: the parameter that user equipment (UE) is measured Pattern according to the discontinuous reception modes DRX Pattern and the measurement pattern of network equipment configuration, calculate the radio frames that receives burst Rx Burst and measurement place on opportunity, wherein, receive burst Rx Burst and occur in different radio frames opportunity with measurement; Described UE receives information transmitted by network-side equipment, and described UE receives information in the radio frames at the Rx Burst place that described DRXPattern determines, and measures opportunity in the measurement that described measurement Pattern determines.
As shown in Figure 1, measure the computational methods flow chart on opportunity, may further comprise the steps for the embodiment of the invention:
S101:UE calculates the radio frames at Rx Burst and place on the opportunity of measurement, and wherein, Rx Burst occurs in different radio frames opportunity with measurement.
In step S101, the parameter that user equipment (UE) is measured Pattern according to the discontinuous reception modes DRX Pattern and the measurement pattern of network equipment configuration, calculate the radio frames that receives burst Rx Burst and measurement place on opportunity, wherein, receive burst Rx Burst and occur in different radio frames opportunity with measurement.
For example, the parameter of network equipment configuration discontinuous reception modes DRX Pattern and measurement pattern measurement Pattern may further comprise the steps:
The reception burst Rx Burst that DRX Pattern determines is the radio frames that sends information to UE, and corresponding system frame number SFN is eligible: (SFN-H-RNTI) mod (DRX_cycle)＜Rx_burst, and wherein, H-RNTI is the specific deviant Offset of UE;
Measuring the definite radio frames of Pattern is the measurement opportunity of described UE, and the system frame number SFN of described measurement correspondence on opportunity is eligible:
SFN+Offset_M＝H-RNTI?mod(M_REP)+n*M_REP (3)
Wherein, H-RNTI is the specific deviant Offset of UE, the time offset of deviant Offset_M for increasing.
Formula (3) increases time migration Offset_M on the basis of formula (2), Offset_M is the plus or minus integer, and other parameters are according to the definition of existing protocol.The value of Offset_M can be notified UE and/or NodeB by the mode of predefine or high-level signaling, described predefined mode, get certain fixed value as prior agreement Offset_M, the mode of described high-level signaling notice, as the value of Offset_M is broadcasted in system message, perhaps in the RRC signaling, additionally increase information unit IE indicates value from described Offset_M to UE, and/or by additionally increasing information unit IE indicates value from described Offset_M to NodeB in NBAP (NodeB ApplicationProtocol, the NodeB application protocol) signaling.
Be that the network equipment notifies described UE and/or base station node B to comprise by high-level signaling: the value of Offset_M is broadcasted in system message, perhaps in the RRC signaling, additionally increase the value that information unit IE indicates described Offset_M to UE, and/or by additionally increasing information unit IE indicates value from described Offset_M to NodeB in the NBAP signaling.
Calculate according to above-mentioned formula (3) when measuring Pattern, and when DRX Pattern calculates according to original formula (1), if Offset_M＞0, be equivalent to shift to an earlier date the time of Offset_M on the original basis with measuring Pattern, if Offset_M＜0, be equivalent to lag behind on the original basis (time Offset_M) with measuring Pattern, so reached the purpose that the opportunity of will measuring and RX stagger constantly, wherein, a kind of embodiment that optimizes is, get Offset_M=1, as shown in Figure 4, and then measurement is exactly Rx Burst after opportunity.
In addition, the parameter of network equipment configuration discontinuous reception modes DRX Pattern and measurement pattern measurement Pattern can also may further comprise the steps:
The reception burst Rx Burst that DRX Pattern determines is the radio frames that sends information to UE, and corresponding system frame number SFN is eligible:
(SFN-H-RNTI+Offset_DRX)mod(DRX_cycle)＜Rx_burst(4)
Wherein, H-RNTI is the specific deviant Offset of UE, the time offset of deviant Offset_DRX for increasing;
Measuring the definite radio frames of Pattern is the measurement opportunity of described UE, and the system frame number SFN of described measurement correspondence on opportunity is eligible: SFN=H-RNTI mod (M_REP)+n*M_REP, wherein, H-RNTI is the specific deviant Offset of UE.

Therefore, aforementioned calculation formula (4) increases time migration Offset_DRX on the basis of formula (1), and Offset_DRX is the plus or minus integer, and other parameters are with the definition of preamble.The possible configuration mode of Offset_DRX is similar to the situation of Offset_M.
Similarly, when DRX Pattern calculates according to formula (4), and when measurement is calculated according to original formula (1) opportunity, if Offset_DRX＞0, be equivalent to DRX Pattern has been shifted to an earlier date on the original basis the time of Offset_DRX, if Offset_DRX＜0, being equivalent to DRX Pattern has been lagged behind on the original basis, (time Offset_DRX) is so reached the purpose that the opportunity of will measuring and RX stagger constantly.Wherein, if get Offset_DRX=-1, effect is identical with situation shown in Figure 4, and and then be exactly Rx Burst afterwards the opportunity of promptly measuring.
As embodiments of the invention, the parameter that network equipment configuration discontinuous reception modes DRX Pattern and measurement pattern are measured Pattern can also may further comprise the steps:

Wherein, deviant Delta_M or Delta_Cycle are that the agreement predefine value or the described network equipment are notified described UE and/or base station node B by high-level signaling.
Because DRX Cycle and measurement Cycle Length on opportunity all are 2 integral number powers in the existing system, the relation that has integer between the two, DRX Pattern and the generation of measuring the Pattern collision have been caused, so this scheme changes the value of DRX Cycle and/or measurement Cycle Length on opportunity, make the relation that does not have integral multiple between the two, the probability that elimination or reduction Pattern bump.
As suppose M_REP=2
k+ Delta_M, or DRX Cylce become Cycle_Length+Delta_Cycle, wherein, parameter k, Cycle_Length are measurement and the DRX parameters that the mode by former protocols having regulation disposes, the implication of parameter is constant, and Delta_M, Delta_Cycle are the plus or minus integers.Be exemplified below, DRX Cycle value does not make an amendment, DRX Cycle=4, and M_REP=2
k+ 1=9 (when k=3), because the value of DRX Cycle configuration still is 2 integral number power, with 4 is to repeat in the cycle, and M_REP has become non-2 integral number power, with 9 is to repeat in the cycle, calculate as can be known, the probability that the Pattern collision takes place reduces greatly, reaches the purpose that measurement opportunity and RX are staggered constantly.
