Abstract: A method is provided for receiving, at a receiving device, a control information message from a transmitting device. An example method includes determining at a user equipment (UE) a status of the UE and monitoring at the UE based on the status either a common search space (CSS) of a cell or a UE-specific search space (USS) of the cell. The cell is a cell of a secondary eNodeB for communicating with the UE. The method may further include monitoring a CSS and a USS of a cell of a master eNodeB (MeNB) simultaneously while monitoring either the CSS or the USS of the cell of the secondary eNodeB. The status may be a status of the UE with respect to a Random Access Channel (RACH) procedure with the cell.

Abstract: At least one example embodiment discloses a method of scheduling communications in a network having a plurality of base stations covering cells, respectively. The method includes obtaining a first coordination matrix, by a first base station, based on channel state information from at least one user equipment (UE), the first coordination matrix indicating scheduling information and first weights associated with subband transmissions for the first base station, transmitting the first coordination matrix to at least another base station of the plurality of base stations, receiving, by the first base station, a second coordination matrix from the at least another base station, the second coordination matrix indicating second weights associated with subband transmissions for the second base station, and transmitting, by the first base station, in subbands where the associated first weights are greater than the associated second weights.

Abstract: Embodiments of the present invention include a system for transmitting a precoding codebook over an air interface. The system includes a first station configured to signal a set of indicators via at least one antenna to a second station from which the precoding codebook is derived at the second station based on the signaled set of indicators. The set of indicators includes less information than the precoding codebook.

Abstract: At least one example embodiment discloses a method of determining uplink resources. The method includes assigning index values for control channel elements. The control channel elements are allocated to at least one of first and second control channel transmission sets. The uplink resources being are based on the index values and an uplink resource for the first control channel transmission is different than an uplink resource for the second control channel transmission.
