Signalling for Coordinated Multi-Point Transmission and Reception (CoMP)

In a wireless communications system including a first transmission point and a second transmission point, a wireless communications method implemented in the second transmission point supporting coordinated multi-point transmission and reception (CoMP), the wireless communications method comprising:

• receiving from the first transmission point one or more CoMP hypothesis sets;
• and
• receiving from the first transmission point a benefit metric corresponding to each CoMP hypothesis set,
• wherein the benefit metric can be a negative value.
