  • 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.

  • Publication number: 20170223589
    Abstract: Various embodiments include multi-subscription multi-standby (MSMS) communication devices and methods for managing reception of data using a first subscription following a tune-away by a radio frequency (RF) resource chain from the first subscription to a second subscription. In various embodiments the MSMS communication device may receive data over the first subscription during a warm-up period of the RF resource chain following completion of the tune-away. In some embodiments, the device processor may receive the data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined before the tune-away. In some embodiments, the device processor may receive data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined initially during the warm-up period.

  • 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: 20150382362
    Abstract: Methods, systems, and devices are described for identifying and mitigating in-device coexistence interference for multicarrier systems implementing soft combining decoding techniques. In some aspects, the described techniques include identifying time-frequency resources of a received signal subject to coexistence interference at a transceiver of a wireless device. The time-frequency resources may include, for example, symbols, slots, code-blocks, sub-frames, subcarriers, etc. Resource-specific mitigation may then be applied to the identified resources, for example, including skipping or nulling the interfered resources in the time domain, frequency domain, or both. In some aspects, the resource-specific mitigation may be performed at the soft-combining stage of the decoding process, such as by skipping or nulling one or more log likelihood ratio (LLR) instances that correspond to the interfered resource(s).

  • Publication number: 20150139015
    Abstract: Various embodiments enable a multi-active mobile communication device to mitigate (manage) interference by a frequency band used by a first subscription with the frequency band used by a second subscription. The device processor may generate modified power measurements for one or more frequency bands of a first subscription and use the modified power measurement(s) to cause the first subscription to switch from the frequency band that interferes with the frequency band of the second subscription. The modified power measurement may be a decreased power measurement of the first frequency band and/or an increased power measurement of a second frequency band that does not interfere with the frequency band of the second subscription. As a result, various embodiments may mitigate or otherwise manage the impact of coexistence interference between the first and second subscriptions of a multi-active mobile communication device without limiting capabilities of the device or changes to the network.

  • Patent number: 6735216
    Abstract: In a code division multiple access communication system, a method and apparatus provide for an efficient testing of operating behavior of a quality indicator bit. The method and the accompanying apparatus include configuring a receiver to expect to receive a communication channel at a full data rate, and transmitting a signal from a transmitter to the receiver. The signal is carrying the communication channel at a data rate other than said full data rate, and at a power level for receiving at the full data rate. Consequently, the receiver fails to receive the communication channel at the full data rate. A received signal to noise ratio of the received signal at the receiver is determined. A value of the quality indicator bit is determined based on the determined signal to noise ratio. The determined value of the quality indicator bit is communicated to the transmitter.

  • Patent number: 6678320
    Abstract: A finite impulse response filter including a first circuit for providing plural delayed signals in response to an input signal. A second circuit is included for multiplying respective ones of the delayed signals by a corresponding coefficient and providing a respective intermediate signal in response thereto. A third circuit selectively changes the sign of respective ones of a first set of the intermediate output signals to provide a set of component in-phase signals. A fourth circuit selectively changes the sign of respective ones of a second set of the intermediate output signals to provide a set of component quadrature signals. The component in-phase signals are combined to provide an in-phase output signal and the component quadrature signals are combined to provide a quadrature output signal. In the illustrative implementation, the coefficients are generated in accordance with an industry standard via a storage device such as a register bank.

  • Patent number: 6286994
    Abstract: A system, method and computer program product that uses an expected output power level to compensate for slowly changing unintentional power fluctuations in a signal transmission system such that the actual transmitted power matches a calculated desired transmit power. Digital expected power data is sampled and filtered to generate an expected output power level. Actual output data is sampled and filtered to generate an actual output power level. A comparator periodically compares the expected output power level to the actual output power level. Preferably, the comparator first removes a correction value from the actual output power level that was added to the transmit signal to correct for unintentional power fluctuations. The resultant ratio or difference is sent to a correction module which generates a correction value therefrom. The correction value is converted to a dB quantity and added to existing correction values.
