Base station employing shared resources among antenna units

摘要

A base station includes a base unit and a plurality of remote antenna units (RAUs). Each of the RAUs includes a physical layer circuit (PHY). The PHYs are configured to each use the same physical layer identifier, but each PHY includes its own hardware for supporting users in the coverage area of that PHY. The base unit controls resource allocation for the RAUs to increase the capacity of the base station and/or reduce interference between PHYs.

主权项

1. An apparatus, comprising:
at least one base unit configured to dynamically allocate physical layer resources for the apparatus; and a plurality of antenna units communicatively coupled to the at least one base unit, wherein: the antenna units are physically separated, at least two of the antenna units are configured to use a common physical layer identifier on a common carrier frequency, the dynamic allocation of the physical layer resources comprises dividing the physical layer resources among the at least two antenna units to mitigate, within a geographical area, potential interference associated with signals from the at least two antenna units, and wherein each of the at least two antenna units is configured to provide mobility management for access terminals operating within coverage of the apparatus, wherein the dynamic allocation of the physical layer resources comprises changing at least one of a first set of uplink scrambling codes used by a first one of the at least two antenna units and changing at least one of a second set of uplink scrambling codes used by a second one of the at least two antenna units in response to determining that a first one of the access terminals has moved from coverage of the first one of the antenna units to the second one of the antenna units.
