Allowable Subject Matter
6. Claims 6, 14, 15, is/are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 6 prior art Xin et al. [US 20210160116 A1]discloses in para [0095] [0095] In an implementation of the embodiment of the present application, the insertion unit is further configured to: when the constellation point modulation performed on the first data sequence is π/2-BPSK, insert the third datum y(j) between each pair of the first datum x(i) and the second datum x(i+1) which are adjacent to each other; where a modulus of y(j) is equal to a modulus of a π/2-BPSK modulated datum, the phase of y(j) is within the angle between x(i) and x(i+1), and an angle between y(j) and x(i) and an angle between y(j) and x(i+1) each have a value of π/4.
And in para [0100] i and k are both non-negative integers (i is a non-negative integer from 0, 1, . . . , N−1, k is 0, 1, . . . , 2N−2, or k is a non-negative integer from 0, 1, . . . , 2N−1), N is a positive integer, and θ is a constant.
And in prior art Chappaz . [US 20110122970 A1] teaches in [0058] for an input stream comprising k symbols, the complete phase rotation of the constellation diagram 56 which is applied in .pi./2-offset 2PSK modulation at the transition to the k.sup.th symbol is defined by the following expression:
.pi. / 2 - offset 2 P S K Phase Rotation = 4 .times. k .pi. 8 = k .pi. 2 ##EQU00001##
[0059] In 8PSK modulation, possible symbol values are: 0, 1, 2, 3, 4, 5, 6 and 7, which are located at respective positions: 60, 64, 68, 72, 76, 80, 84 and 88. An equivalent phase rotation expression for 3.pi./8-offset 8PSK modulation, expressed in the same terms as the above .pi./2-offset 2PSK phase rotation expression, is defined as follows: 3 .pi. / 8 - offset 8 P S K Phase Rotation = 3 .times. k .pi. 8 ##EQU00002##
And prior art Chen et al. [CN 107040487 B] discloses in para [0104]transmits uplink signal in NB-IoT system, pi/2BPSK and pi/4QPSK. pi/2BPSK uses respectively constellation diagram of two relative rotation pi/2 to modulate or sign phase correction in different symbol period, he BPSK constellation diagram such as the two relative rotation pi/2 is a different constellation diagram version of the BPSK constellation diagram; two QPSK constellation diagrams/N1, of the relative rotation pi/4 is a different constellation diagram version of the QPSK constellation diagram

For claim 14
wherein the second indication information indicates an identifier of a modulation constellation diagram group to which the first modulation constellation diagram belongs and an index of the first modulation constellation diagram in the modulation constellation diagram group.
Therefore, claim 6 would be allowable if rewritten or amended to overcome the objections set forth in this office action and in independent form including all of the limitations of the base claim and any intervening claims. Dependent claims of claim 18 would also be allowable for the same above reasons.
