First Claim
1. A method to facilitate communications by an evolved Node B (eNB), the method comprising:
- determining an angle of arrival associated with individual user equipments (UEs) of a plurality of UEs in a connected mode with the eNB;
determining a timing advance associated with the individual UEs;
estimating a UE location of the individual UEs within a coverage area of the eNB based on the respective angle of arrival and timing advance;
assigning the individual UEs to one of a plurality of bins, individual bins of the plurality of bins corresponding to a range of values for the angle of arrival and a range of values for the timing advance;
averaging reference signal received power (RSRP) measurements or reference signal received quality (RSRQ) measurements received from a plurality of the individual UEs assigned to a same individual bin to obtain an average RSRP measurement or an average RSRQ measurement for the respective individual bin; and
adjusting, in accordance with a capacity and coverage optimization (CCO) function, one or more parameters for communications by the eNB based on the average RSRP measurements or average RSRQ measurements for respective individual bins of the plurality of bins.

Abstract
Methods, apparatuses, and systems are described related to generating and using a user equipment (UE) location distribution in a wireless communication network. In embodiments, an evolved Node B (eNB) may determine an angle of arrival (AoA) and a timing advance (Tadv) for individual UEs of a plurality of UEs that are in a connected mode with the eNB. The eNB may assign the individual UEs to one of a plurality of bins to generate a UE location distribution. Individual bins of the plurality of bins may correspond to a range of values for the AoA and a range of values for the Tadv to indicate a physical location of the corresponding UEs. The eNB may transmit the UE location distribution to a network management entity, which may adjust one or more parameters of the eNB, based on the UE location distribution, using a capacity and coverage optimization (CCO) function.
