Embodiment Construction

[0036] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0037] Various embodiments provide transmission, reception and signaling methods and systems for adaptive transmission in wireless networks. A network node / carrier / antenna set may be in a reduced activity mode and may only perform limited monitoring activities (eg the node does not perform CRS or CSI-RS transmission). In some embodiments, the reduced active mode may include limited transmission of discovery reference signals (DRS) for the UE to detect small cells. Such a network node / carrier / antenna set may need to switch to data transmission / reception (Tx / Rx) mod...

Abstract

A method for cell adaptation includes receiving, by a user equipment (UE), one or more transmission parameters for a transition reference signal (TRS). One or more cells is transitioned between a reduced activity mode and an active transmission and reception mode in accordance with the TRS. The method further includes the UE determining whether or not to transmit the TRS in accordance with one or more TRS transmission criteria, and the UE transmitting the TRS in accordance with the one or more transmission parameters.

Description

[0001] This application claims U.S. Patent Application Serial No. 14 / 254,691, entitled "Systems and Methods for Adaptive Transmissions in Wireless Networks," filed April 16, 2014, and filed April 17, 2013 Priority claim to U.S. Provisional Patent Application No. 61 / 813,062, entitled "Systems and Methods for Adaptive Transmissions in Wireless Networks," the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to systems and methods for wireless communications and, in particular embodiments, to systems and methods for adaptive transmission in wireless networks. Background technique [0003] Wireless communication systems include Long Term Evolution (LTE), LTE-A, and LTE-Advanced systems. Typically, in modern wireless communication systems, there are multiple NodeBs (NBs) (often also referred to as base stations, communication controllers or eNodeBs (enhanced NBs), etc. network nodes such as High Speed ​​Packet A...
