Abstract: The exemplary embodiments provide at least a method for receiving from a serving access node information of communications of at least one other access node, the information comprising interference conditions of at least one distributed enhanced physical downlink control channel set used by the at least one other access node, and the communications comprising transmissions from two or more antenna ports of the at least one other access node, estimating different interference conditions with respect to communications from different antenna ports of the two or more antenna ports based on the information; and using an enhanced receiver based on the estimated at least two different interference conditions. Further, the exemplary embodiments provide at least determining by a serving access node information of interference conditions of at least one distributed enhanced physical downlink control channel set used by at least one other access node; and sending towards user equipment the information.

Abstract: A method and apparatus can be configured to measure channel conditions of a first channel (310). The first channel can correspond to a first frequency. The method can also include predicting whether the channel conditions of a second channel are favorable for offloading communication occurring on the first channel to the second channel based on measurements performed on the first channel (320). The second channel can correspond to a second frequency. The second frequency can be higher than the first frequency. The method can also include determining a rate of occurrence for monitoring the second channel based on the results of the predicting (330).

Abstract: This document discloses a solution for enabling overlapping transmissions in a wireless network. An apparatus may be arranged to detect a response to a frame, the response transmitted from a first device as addressed to a second device different from the apparatus and comprising a first value indicating a received signal strength between the first device and the second device. The apparatus may determine a second value indicating a received signal strength of the response in the apparatus and cause transmission of a frame that overlaps with a transmission between the first device and the second device only if the second value in proportion to the first value is below a determined threshold.

Abstract: Disclosed is a method and an apparatus providing antenna port sharing and a demodulation reference signals (DMRS) based precoding scheme for a distributed enhanced physical downlink control channel (E-PDCCH) using, for example, spatial frequency block codes (SFBC)/frequency selective transmit diversity (FSTD) transmit diversity. The method exhibits the same performance as SFBC/FSTD transmit diversity using un-precoded DMRS while not prohibiting another UEs' localized E-PDCCH to be potentially multiplexed in a same physical resource block (PRB) pair. The SFBC/FSTD transmission is facilitated by mapping a subset of layers to DMRS ports used by other UEs for localized and beamformed transmission, while the precoders for the remaining layers arc selected to be orthogonal to the other UEs precoders thereby providing good performance wide minimizing DMRS port usage. Specifically, no additional DMRS ports are needed for spatial diversity transmission.
