  • Patent number: 8442155
    Abstract: A procedure for compensating the DC component inherent in any radio frequency chain making it possible from a single measurement, generally located in the digital stage, to determine a set of multiple compensation values that must be applied to multiple compensation points of the analogue chain. The compensation values are calculated by an iterative process converging towards a cancellation of the DC component and avoid saturating amplification components and components of the analogue digital converter.

  • Patent number: 8442473
    Abstract: Data transmitted via a combination of radio frequency RF signals using carrier aggregation CA is received, each RF signal occupying a respective RF band, the bands being arranged in two groups separated in frequency by a first frequency region, the first of the two groups occupying a wider frequency region than the second group. Inphase and quadrature components of the RF signals are filtered using a first bandpass filter bandwidth to give first bandpass filtered components and filtered using a second bandpass filter bandwidth, different from the first bandpass filter bandwidth, to give second bandpass filtered components. A reconfigurable receiver is configurable to a first mode to receive the combination of RF signals, and is also configurable to at least a second mode. A filter is configured, in different modes, to use a first or a lowpass bandpass filter bandwidth.

  • Publication number: 20130114401
    Abstract: A method, apparatus and computer program product are provided in order to allow for reselection of a TTI resource, such as in an instance in which a mobile terminal has moved to a different portion of the coverage area and/or in an instance in which the TTI resource was initially incorrectly selected, such as based upon an inaccurate measurement. In the context of a method, a first TTI resource is selected in conjunction with an uplink. The method also detects a failure condition associated with the uplink and selects a second TTI resource, different than the first TTI resource, in response to detection of the failure condition.

  • Patent number: 8437754
    Abstract: A user equipment UE receives (302) from a serving cell indications of frequency bands supported by neighbor cells/frequencies, at least one individual neighbor cell/frequency supporting a plurality of frequency bands. The neighbor cells/frequencies are filtered (304) to retain only those that are indicated to support a frequency band or frequency bands which are also supported by the UE. Examples are given of various system information blocks for sending the frequency band indications to the UE. In one embodiment (310), they are arranged in an information element IE having an entry for each of the neighbor cells/frequencies and a list of frequency bands for each entry. In another (312), the IE has an index and an associated frequency band(s) where a value of the index indicates that one or more of the neighbor cells/frequencies referred to by the index belongs to the associated frequency band(s).

  • Patent number: 8433321
    Abstract: A method, apparatus and computer program product are provided for supplying information regarding a neighbor cell following cell reselection in a manner that reduces the signaling load on the network and conserves battery consumption by a mobile terminal. In this regard, the method, apparatus and computer program product do not blindly provide information regarding a neighbor cell that the current cell has already collected, but, instead, first determines if the neighbor information regarding a prior cell is different than and therefore will add to the information regarding neighbor cells that is already maintained by the current cell. Only after making such a determination may a mobile terminal signal the current cell as to the availability of neighbor information regarding a prior cell.
