For ease of description, the choosing between pi/2-BPSK modulation and QPSK modulation is explained below in the embodiment of the present application Select principle:

In the case where identical coding mode, in order to guarantee that transmission rate is higher, user equipment can choose Block Error Rate (block error rate, BLER) lower modulation coding scheme.Since pi/2-BPSK modulation code rate is QPSK modulation code rate 2 times, therefore, under the conditions of same signal-to-noise ratio QPSK modulation theory performance better than pi/2-BPSK modulate.

Assuming that pi/2-BPSK modulation and QPSK, which are modulated at receiving end, identical signal-to-noise ratio, i.e. two kinds of modulation systems have phase Same signal-to-noise ratio.As shown in table 3, when it is 1 that TBS index, which is 0 and TBS index, two kinds of modulation system performances are identical, and pi/2- The code rate of BPSK modulation is higher, therefore, selects pi/2-BPSK modulation more excellent；When TBS index is greater than 3, the performance of QPSK modulation It is more excellent.Therefore, when configuring MCS table, TBS index is pi/2-BPSK modulation for 0 and 1 corresponding modulation system, and other The corresponding modulation system of TBS index is QPSK.However, in practical applications, pi/2-BPSK modulation has biggish transmission power, I.e. pi/2-BPSK modulated signal has higher signal-to-noise ratio in receiving end.In conjunction with table 3, it is assumed that used using pi/2-BPSK modulation ratio QPSK is modulated with the transmission power advantage of 1dB, then is 0-3 for TBS index, available preferably using pi/2-BPSK modulation Performance modulates available better performance using QPSK when call number is greater than 3.

It should be noted that on the one hand, the table of above-mentioned form can not use directly, as needed need to determine using preceding It include pi/2-BPSK modulation and QPSK modulation specially any modulation system in C modulation system set.On the other hand, work as volume Code mode indicates that the TBS index in the embodiment of the present application is not incremented by according to MCS call number, TBS index using TBS index It is not continuous call number, the embodiment of the present application is not especially limited this.Illustratively, table 4a is another MCS table Lattice.Table 4a contains MCS index, order of modulation, several information such as code rate and spectrum efficiency, wherein the code rate in table 4a be with Target bit rate is indicated multiplied by 1024 form.The order of modulation of modulation system set including pi/2-BPSK and QPSK can be used One parameter indicates that the value of the parameter is the different values that may be configured to, and different values respectively indicates different modulation methods Formula.Such as table 4a can be indicated with q include the modulation system set of pi/2-BPSK and QPSK order of modulation.Q can be configured to 1 or Person 2, wherein 1 corresponding pi/2-BPSK modulation, 2 corresponding QPSK modulation.The half that target bit rate when q is 2 is q when being 1.Table 4a In, the corresponding order of modulation of MCS index 0 and 1 is q.

Whether the network equipment and user equipment can support pi/2-BPSK to determine the value of q according to user equipment.Such as: When user equipment supports pi/2-BPSK modulation, the network equipment and user equipment can determine that q is 1.It is, if user sets When standby support pi/2-BPSK modulation, the network equipment and user equipment can determine that q is 1；When user equipment does not support pi/2-BPSK When, the network equipment and user equipment can determine that q is 2.It is, if user equipment supports pi/2-BPSK modulation and Xiang Ji Station is reported, then modulation system is pi/2BPSK.Otherwise modulation system is QPSK.In other words, user equipment do not support π/ 2-BPSK or user equipment do not report whether support pi/2-BPSK, then modulation system is QPSK.

If the network equipment determines that user equipment supports pi/2-BPSK modulation, the network equipment determines that target call number is corresponding Modulation system is pi/2-BPSK modulation, for example, the network equipment determines that the corresponding order of modulation of MCS index 0 and 1 is pi/2-BPSK tune System.Alternatively, the network equipment determines target call number pair if the network equipment determines that user equipment does not support pi/2-BPSK to modulate The modulation system answered is QPSK modulation, for example the network equipment determines the corresponding order of modulation of MCS index 0 and 1 for QPSK modulation.Net Network equipment can determine whether user equipment supports pi/2-BPSK by the ability information of the user equipment of user equipment to report Modulation.The ability information of user equipment includes the information whether user equipment supports pi/2-BPSK to modulate.

User equipment reports the ability information of the user equipment to the network equipment.If user equipment supports pi/2-BPSK tune System, user equipment determine the corresponding modulation system of target call number for pi/2-BPSK modulation, for example, the user equipment determines MCS 0 and 1 corresponding order of modulation is indexed as pi/2-BPSK modulation.Alternatively, if user equipment does not support pi/2-BPSK to modulate, the use Family equipment determines that the corresponding modulation system of target call number determines MCS index 0 and 1 pair for QPSK modulation, such as the user equipment The order of modulation answered is QPSK modulation.

If the network equipment does not obtain the information whether user equipment supports pi/2-BPSK to modulate, the network equipment and user Equipment determines that the corresponding modulation system of target call number is preset modulation system, and the preset modulation system is pi/2-BPSK Modulation or QPSK modulation.Alternatively, if user equipment does not report the ability information of the equipment to the network equipment, the network equipment and User equipment determines that the corresponding modulation system of target call number is preset modulation system, and the preset modulation system is pi/2- BPSK modulation or QPSK modulation.

If the network equipment does not obtain the information whether user equipment supports pi/2-BPSK to modulate, alternatively,

Such as in initial access phase, user equipment does not also report the information to the network equipment, then the network equipment and user Equipment can determine the corresponding order of modulation of MCS index and code rate by the rule made an appointment, it may be assumed that corresponding to agreement MCS Order of modulation be modulation system set included in one of which modulation system.For example, it is assumed that table 4a is uplink MCS table Lattice in 3 uplink of message in the random access procedure, can arrange tune corresponding to the MCS index 0 and index 1 in table 4a Order processed is 2, i.e. q=2.The targeted scene of this method is that QPSK modulation is the essential feature of user equipment and pi/2 BPSK modulation is optional feature such case of user equipment.
