Patent number: 9510356Abstract: 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.Type: GrantFiled: September 28, 2012Date of Patent: November 29, 2016Assignee: BROADCOM CORPORATIONInventors: Jari Isokangas, Wei Hong, Haiming Wang, Na Wei, Antti Oskari Immonen, Jouni Kristian Kaukovuori

Patent number: 9509416Abstract: 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.Type: GrantFiled: September 20, 2013Date of Patent: November 29, 2016Assignee: BROADCOM CORPORATIONInventors: Bruce J. Currivan, Thomas J. Kolze

Patent number: 9504059Abstract: A device with concurrent long-term evolution (LTE) and WLAN uplink transmission includes a WLAN transceiver coupled to an LTE transceiver via an interface. The LTE transceiver includes an LTE Layer-1 module that determines whether an LTE data downlink activity is scheduled for an LTE downlink sub-frame of an LTE time frame, based on information in a first portion of the LTE downlink sub-frame.

Patent number: 9503114Abstract: A multi-lane analog to digital converter (ADC) samples an analog input according to multiple phases of a sampling clock. Ideally, the multiple phases of the sampling clock are non-overlapping. The multi-lane ADC includes one or more reset switches to remove any residual samples that can remain after their conversion from an analog signal domain to a digital signal domain. As a result of this removal, the multiple phases of the sampling clock need not to ideally coincide with one other. Rather, some overlap between the multiple phases of the sampling clock can exist while having digital output samples still accurately represent the analog input.Type: GrantFiled: September 15, 2015Date of Patent: November 22, 2016Assignee: Broadcom CorporationInventors: Tamer Ali, Ramy Mohamed Yousry Ahmed Elsayed Awad, Jun Cao

Patent number: 9503303Abstract: The present disclosure presents symbol mapping for any desired error correction code (ECC) and/or uncoded modulation. A cross-shaped constellation is employed to perform symbol mapping. The cross-shaped constellation is generated from a rectangle-shaped constellation.
