    Abstract: System and method embodiments are provided for signaling reference signals and Channel State Information (CSI) feedback for wireless communications. An embodiment method implemented by a user equipment (UE) for wireless communications measurements and CSI feedback includes receiving, from a network, at least one of a first index that indicates a corresponding non-zero-power CSI reference signal (CSI-RS) resource, a second index that indicates a corresponding zero-power CSI-RS resource, a third index that indicates a corresponding CSI-RS resource for interference measurement, and a fourth index that indicates a corresponding channel quality indicator (CQI) report configuration. The method also includes receiving, from the network, at least one of a fifth index that indicates a corresponding periodic CQI report in accordance with the CQI report configuration indicated by the fourth index, and a sixth index that indicates a corresponding aperiodic CQI report in accordance with the CQI report configuration indicated by the fourth index.

    Abstract: System and method embodiments are provided for network adaption and utilization of a discovery signal (DS). In an embodiment, a method in a UE for communicating in a wireless network includes receiving a parameter(s) from a network controller, wherein the parameter provides the UE with an activation time frame within which the UE can expect to receive a common reference signal (CRS) from a network component, a deactivation time frame within which the UE is not to expect to receive the CRS, and information for receiving and processing a DS from the network component; receiving the DS from the network component, wherein a structure and format of the DS conforms to the parameter received by the UE; refraining from attempting to perform CRS based procedures when the CRS is not received; and performing one of synchronization, cell identification, and DS based radio resource management (RRM) measurements according to the DS.

    Abstract: Communications in a wireless network for carrier Selection and switching are provided. A terminal in the wireless network is simultaneously receiving data on at most m carriers. A base station in the wireless network sends an activation command associated with more than m carriers to the terminal. The terminal activates the more than m carriers. Then the base station selects a first subset from the activated carriers, and sends a first monitoring command associated with the first subset via a first physical-layer signaling to the terminal. When load and/or interference situations are changed, the base station selects a second subset from the activated carriers, and sends a second monitoring command associated with the second subset via a second physical-layer signaling to the terminal, wherein the first subset is different from the second subset.
