Abstract: Certain aspects of the present disclosure relate to methods and apparatus for cell DTX (Discontinuous Transmission) scheduling. A Base Station (BS) determines an operational schedule for the BS including at least one ON period and at least one OFF period, wherein the BS provides a reduced level of service during the at least one OFF period relative to the at least one ON period. The BS transmits the determined operational schedule. A User Equipment (UE) receives the BS's operational schedule and determines, based on the BS's operational schedule and its own operational schedule also including ON and OFF periods, whether to perform at least one service associated with the BS.

Abstract: Methods and techniques are described for economically supporting a cluster of transmission points (TPs) that serve as positioning only beacons in a wireless network. A TP may broadcast a positioning reference signal (PRS) for positioning of a user equipment (UE) using the 3GPP OTDOA method for LTE wireless access. TPs are controlled by a TP Controller (TPC) that may function as an evolved NodeB (eNB) or Home eNB. A TPC may configure (or retrieve) PRS parameters in (or from) a controlled TP, may provide an accurate time reference to the TP and may be connected to the TP using a LAN or WLAN. A location server such as an E-SMLC may retrieve information for TPs, such as PRS parameters, TP location, and TP identity, from a controlling TPC, e.g. using the LPPa protocol. An E-SMLC may access a TPC via an MME to which the TPC may be connected.
