摘要： 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.

A base station simulcast controller module may be coupled with each antenna port, and may be adapted to transmit downlink transmissions over a plurality of remote antenna units, with two or more of the remote antenna units simulcasting downlink transmissions as a simulcasting group. In response to one or more obtained network traffic parameters, the base station simulcast controller module may modify the simulcasting group to include at least one different remote antenna unit. Methods operational on base station may include transmitting downlink transmissions over a plurality of remote antenna units, where two or more of the remote antenna units form a simulcasting group. The simulcasting group can be modified to include at least one different remote antenna unit in response to one or more obtained network traffic parameters.

摘要： A method for interference cancellation in a device that receives transmissions from multiple sources is disclosed. The method includes receiving multiple slots, each including a pilot segment and a traffic segment. A first one of the slots includes information indicating an activity level of a traffic segment of the first one of the slots. The method also includes calculating a value associated with interference among the plurality of slots, utilizing the information indicating the activity level to account for an amount of interference attributable to the first one of the slots. Furthermore, channel conditions are estimated for a second one of the slots using the value associated with the amount of interference. The method also includes processing the second one of the slots according to the estimated channel conditions.
