Abstract
A radio communication apparatus receives or generates a base address seed, and generates data-channel access addresses from the seed. Each access address corresponds to a respective data-channel identifier, and is generated by setting a bit at a common first bit position to the value of a bit at a first common predetermined bit position in the base address seed or in the respective data-channel identifier; by setting a bit at a common second bit position to the bitwise complement of this value; and by setting one or more remaining bit positions in dependence on values at one or more bit positions in the base address seed and one or more bit positions in the respective data-channel identifier that are not the first common predetermined bit position. The apparatus can send or receive a radio data packet comprising an access address from the generated set.
