Claim Text:
1. A method, implemented at a computer system that includes one or more processors, for selecting a phase offset vector used in a virtual antenna mapping arrangement in a mobile communications network, the method comprising: identifying an existing phase offset vector that is determined to be in need of an update, wherein the existing phase offset vector is being used by a plurality of radio-frequency branches; identifying a number of possible replacement phase offset vectors; generating a subset of phase offset vectors from among the identified possible replacement phase offset vectors; transmitting a plurality of radio-frequency signals to one or more user devices of the mobile communications network, wherein each transmitted radio-frequency signal was acted upon by at least one phase offset vector included in the subset of phase offset vectors; in response to transmitting the plurality of radio-frequency signals, receiving signal quality information from the one or more user devices; and based at least partially on the received signal quality information, selecting, from among the subset of phase offset vectors, a particular phase offset vector to replace the existing phase offset vector.
