A wireless communication network is configured to provide distributed diversity transmissions, wherein different diversity-coded versions of the same information signal are transmitted from each of two or more network sectors. The diversity-coded versions of the information signal are based on space-time or space-frequency codes, and the information signal may comprise a dedicated channel signal targeted to an individual user or a broadcast signa l targeted to one or more users. Thus, spaced-apart network transmitters, whic h may be located at the same cell site, or at different cell sites, are configured to transmit diversity-coded versions of a given information signa l and, in this manner, the advantages of space-time and/or space frequency transmission coding may be applied across multiple sectors of a communicatio n network. Such transmissions may be used to improve soft and softer handoff reception of dedicated channel signals, and to improve reception of Broadcas t- Multicast Services (BCMCS) signals, or the like.
