1. A method of enhancing reception of information at a user equipment (UE) from an Active Coordination Set (ACS), the ACS including a plurality of base stations, and the method comprising:
selecting, by the ACS of a wireless network system, a redundancy scheme from a plurality of sequential data payload redundancy schemes corresponding to a plurality of time domain resources;
providing, by the ACS of the wireless network system to the UE via one or more radio interfaces and one or more pilot signals generated by the plurality of base stations, an indication of the redundancy scheme and at least one of:
first information indicative of (i) a first subset of N time domain resources of a plurality of time domain resources allocated for use by a first base station of the ACS to deliver communications between the ACS and the UE, and (ii) a first beam identifier uniquely identifying a first set of spatial domain resources utilized by the ACS; or
second information indicative of (i) a second subset of M time domain resources of the plurality of time domain resources allocated for use by a second base station of the ACS to deliver communications between the ACS and the UE, with M≠N, and (ii) a second beam identifier uniquely identifying a second set of spatial domain resources utilized by the ACS, with the second set of spatial domain resources different from the first set of spatial domain resources;
jointly transmitting, from the ACS to the UE via two or more radio interfaces, a data payload utilizing the first subset of time domain resources and the first set of spatial domain resources and also utilizing the second subset of time domain resources and the second set of spatial domain resources; and
jointly retransmitting, from the ACS to the UE via the two or more radio interfaces in accordance with the redundancy scheme, at least a portion of the data payload using the first set of spatial domain resources and the second set of spatial domain resources.
