Abstract:
Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.
