  • Publication number: 20170170998
    Abstract: Interference may affect numerous communication systems. Thus, certain wireless communication systems that rely on combining transmitted repetitions of information may benefit from interference removal techniques, such as those that provide pre-combiner interference removal. A method can include receiving, from a transmitter, multiple repetitions of a same information sent from the transmitter over a channel. The method can also include removing interference from the respective repetitions. The method can further include combining the interference-removed repetitions. The method can additionally include performing channel estimation based on the combined interference-removed repetitions. The method can also include retrieving information corresponding to the same information sent in the multiple repetitions based on the channel estimation and combined interference-removed repetitions.

  • Publication number: 20170164281
    Abstract: A method of carrying out dual connectivity with a secondary access node and an apparatus is provided. A mode of operation of a user equipment is determined in dependence on the presence of bearers mapped to the secondary access node. Operating in a first mode occurs when it is determined that one or more bearers are mapped to a secondary access node. Operation in a second mode occurs when it is determined that no bearers are mapped to the secondary no access node. The second mode comprises limiting a listening time to a downlink channel from the secondary access node with respect to the first mode.
