  • Patent number: 10244426
    Abstract: Aspects of frequency error detection with Physical Broadcast CHannel (PBCH) frequency hypothesis are described. For example, a method and apparatus are disclosed for frequency tracking in a user equipment (UE) may include detecting a change in frequency that exceeds a pull-in range of a frequency tracking loop (FTL) of the UE. The method and apparatus may also include identifying a tracking recovery frequency in response to the change in frequency being detected, wherein the tracking recover frequency is identified from a set of frequency hypotheses and based on decoding of the PBCH received by the UE. The method and apparatus may further include updating the FTL with the tracking recovery frequency.

  • Patent number: 9930657
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first starting index for transmitting first control information in a first search space, determines a second starting index for transmitting second control information in a second search space, and transmits the second control information in the second search space at the second starting index when the first starting index and the second starting index are not the same value. The apparatus further transmits to a user equipment (UE) control information in a first search space, receives information from the UE corresponding to the transmitted control information, and decodes the received information based on the UE parsing the control information according to the first search space and based on the UE incorrectly parsing the control information according to a second search space.

    Abstract: Disclosed are implementations that include a method, generally performed at a mobile device, including receiving one or more wireless signals transmitted from a wireless node, with the wireless node being configured to operate in at least a first mode of operation to transmit wireless transmissions comprising one or more subframes configured according to a pre-determined first pattern of cell-specific reference signals (CRS) for the wireless node. The method also includes deriving, based on the received one or more wireless signals, at least one resultant signal attribute indicative of an actual CRS pattern for the received one or more wireless signals, and determining whether the at least one resultant signal attribute derived based on the received one or more wireless signals deviates from a corresponding expected at least one signal attribute associated with wireless signals including cell-specific reference signals produced according to the pre-determined first pattern of CRS.

  • Patent number: 9635659
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first decoding candidate in a first search space and a second decoding candidate in a second search space, where the first decoding candidate and the second decoding candidate have a same size but different definitions of information fields, identifies a difference in the information fields, and determines one of the first decoding candidate and the second decoding candidate as a valid candidate based on the identified difference. The apparatus further generates first control information for transmitting in a first search space, codes the first control information, wherein the code applied to the first control information is specific to the first search space and different from code applied to second control information in a second search space, and transmits the coded first control information in the first search space.

  • Publication number: 20170094545
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) utilizing enhanced carrier aggregation (eCA) may identify a limit to the number of channel state feedback (CSF) processes it is capable of supporting. The UE may transmit an indication of this limit to a base station, which may configure the UE for channel state reporting, and send channel state reporting triggers according to the indicated limit. The UE's determination of the limit to the number of CSF processes may be based on various transmit or receive antenna configurations. A single trigger may correspond to reports covering multiple subframes and/or component carriers. The base station may also arrange the channel state reporting configuration to reduce the peak number of channel state reports that the UE processes during each subframe. The UE may also determine that a number of channel state processes needed to support channel state reporting in a subframe exceeds its capacity.

  • Patent number: 9451652
    Abstract: In wireless communication networks using carrier aggregation, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of the communication link with the secondary cell. When a failure event is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in order to save power and resources.

  • Patent number: 9338668
    Abstract: In a wireless communication system, carrier aggregation may be used to provide desired amounts of bandwidth, where a primary carrier and one or more secondary carriers are aggregated. At the receive side of a system in which the aggregated carriers are in a single frequency band, an amplifier may be used to apply a common gain to the aggregated carriers in the single frequency band, and the common gain may be determined as a function of indications of received signal quality associated with groups of aggregated carriers containing one or more of the aggregated carriers, where one group contains the primary carrier and possible one or more secondary carriers and another group contains only secondary carriers.

  • Patent number: 9226248
    Abstract: In a first configuration, an apparatus determines subframes, in a radio frame, used by one or more neighboring BSs for providing services, and sends information to a UE indicating the determined subframes. In a second configuration, an apparatus determines subframes, in a radio frame, used by one or more neighboring BSs for providing services, transmits with a first power in remaining subframes other than the determined subframes in the radio frame, determines a second power based on the first power such that a difference between the second power and the first power is less than a threshold, and transmits with the second power in a subset of symbols in the determined subframes. In a third configuration, an apparatus receives information from a BS indicating subframes, in a radio frame, used by one or more neighboring BSs for providing services, and adjusts an AGC gain based on the indicated subframes.

  • Publication number: 20150063259
    Abstract: Systems and methods which provide partial bandwidth support of secondary cells for Carrier Aggregation (referred to as Partial Bandwidth Carrier Aggregation) are disclosed. Partial Bandwidth Carrier Aggregation according to embodiments implements wireless links using a plurality of cells with a user equipment (UE), as a means to improve the UE throughput, by using of a portion of the secondary cell bandwidth to accommodate bandwidth limitations of the UE and thereby facilitates the aggregation of component carriers (or portions thereof) when Carrier Aggregation would not otherwise be possible.
