Abstract: Aspects of virtual field buffer based decoding are described. In one embodiment, a current picture field is read from a coded picture buffer comprising coded pictures of video, for example. The current picture may be associated with a top or bottom field polarity. According to decoding and picture output orders, the current picture field is assigned to an available field entry of a virtual field buffer, and an available frame index of a virtual frame map is assigned to the current picture field. The assignment of the available frame index to the current picture field is indicated to a decoder that decodes the current picture field with reference to the assigned frame index. According to aspects of the embodiments described herein, rather than determining complimentary picture fields after decoding, the assignment of complimentary picture fields to virtual frame indexes before decoding provides certain efficiencies.

Abstract: There is proposed a mechanism for controlling communications conducted in multiple frequency bands, in particular for controlling interference caused by intermodulation distortion. When the UE obtains information that an interference caused by an intermodulation distortion produced by a set of first communications performed on at least a first and a second frequency and a second communication performed on a third frequency is present, an indication to the eNB for indicating that an interference situation caused by intermodulation distortion exists. The eNB receiving this indication is enabled to acquire parameters related to the interference situation caused by the intermodulation distortion, and to control, on the basis of the acquired parameters, a communication with the UE by changing communication properties for reducing the interference caused by intermodulation distortion.

Abstract: Many communication systems operate based on orthogonal frequency division multiplexing (OFDM) signaling and/or orthogonal frequency division multiple access (OFDMA) signaling. Within such systems, narrowband interference, which may alternatively be referred to as narrowband ingress, narrowband ingress interference, narrowband noise, etc., may adversely affect one or more subcarriers or tones causing a reduction in performance or even link failure. Such narrowband interference may affect only one or a relatively few tones employed within such communications. When the narrowband interference is identified, a transmission may then be made including one or more information-free tones. A device that receives such a transmission then uses those information-free tones to reduce or cancel the narrowband interference. Such processing may be performed in the frequency-domain, the time domain, or both.

Abstract: Systems and techniques for managing channel reservation in a full-duplex wireless network. A transmitting node sends a media access control frame to a receiving node, including an integrity check field in a header of the frame. Upon performing an integrity check and determining that the media access control frame is addressed to itself, the receiving node sends a transmission so as to reserve the channel. If the receiving node has no data to send, the transmission may be an acknowledgement field, and if the receiving node has data to send, the transmission may be a media access control frame including an integrity check field in a header of the frame.
