  This paper proposes block-level precoder (BLP) designs for a multi-input
single-output (MISO) system that performs joint sensing and communication
across multiple cells and users. The Cramer-Rao-Bound for estimating a target's
azimuth angle is determined for coordinated beamforming (CBF) and coordinated
multi-point (CoMP) scenarios while considering inter-cell communication and
sensing links. The formulated optimization problems to minimize the CRB and
maximize the minimum-signal-to-interference-plus-noise-ratio (SINR) are
non-convex and are represented in the semidefinite relaxed (SDR) form to solve
using an alternate optimization algorithm. The proposed solutions show improved
performance compared to the baseline scenario that neglects the signal
component from neighboring cells.
