The restricted isometry constants (RICs) play an important role in exact recovery theory of sparse signals via l_q(0
=4/3 to guarantee the exact recovery of k sparse signals through the l_1 minimization. This paper aims to establish new RICs bounds via l_q(0
1, (ii)several sufficient conditions can be derived, such as for any 0
=2, for any 1/2
=1, (iii) the bound on \delta_k is given as well for any 0
=2) is even or \delta_k<0.3203 when k(>=3) is odd.
