Patent number: 8793560Abstract: Techniques for efficiently and accurately computing log-likelihood ratio (LLRs) for code bits are described. A set of code bits may be mapped to a modulation symbol in a signal constellation. Different code bits in the set may be associated with different LLR functions. A receiver obtains received symbols for a transmission sent via a communication channel. The receiver derives LLRs for code bits based on the received symbols and piecewise linear approximation of at least one LLR function. The piecewise linear approximation of each LLR function may comprise one or more linear functions for one or more ranges of input values. The receiver may select one of the linear functions for each code bit based on a corresponding received symbol component value. The receiver may then derive an LLR for each code bit based on the linear function selected for that first code bit.Type: GrantFiled: March 13, 2007Date of Patent: July 29, 2014Assignee: Qualcomm IncorporatedInventors: Jonathan Sidi, Rajesh Sundaresan

Patent number: 8634332Abstract: A method for using a joint decoding engine in a wireless device is disclosed. A first symbol stream and a second symbol stream in a received multiple input multiple output (MIMO) signal is determined. A scaled channel estimate for a wireless transmission channel and a scaled noise covariance of the MIMO signal are also determined. The scaled channel estimate and the first symbol stream are whitened. Max log maximum a posteriori (MLM) processing is performed on the whitened first symbol stream to produce a first data stream. The first data stream may be de-rate matched and decoded to produce a decoded first data stream.Type: GrantFiled: April 29, 2010Date of Patent: January 21, 2014Assignee: Qualcomm IncorporatedInventors: Jia Tang, Atul A.

Patent number: 8611941Abstract: Systems and methodologies are described that facilitate efficient power control command management in a wireless communication environment. As described herein, techniques can be utilized by a Node B and/or other network access point to compensate for differences between uplink slot boundaries and a power control command combining period associated with the uplink slot. For example, the timing of Transmitter Power Control (TPC) bit transmission can be altered as described herein such that, if a given cell or cell sector is associated with a radio link set of size 2 or greater and a TPC timing offset of size 2 or less, TPC command information can be buffered and/or otherwise delayed to a slot following the slot in which corresponding channel measurements are obtained in order to prevent efficiency loss associated with combining TPC bits of inverse polarity corresponding to multiple disparate slots.Type: GrantFiled: June 25, 2009Date of Patent: December 17, 2013Assignee: QUALCOMM IncorporatedInventors: Jonathan Sidi, Sharad Deepak Sambhwani

Patent number: 8526319Abstract: Techniques for determining channel quality indicators (CQIs) for a non-linear detector at a user equipment (UE) are described. In one design, the UE may determine at least one parameter (e.g., at least one threshold) based on at least one constellation constrained capacity function. Each threshold may correspond to a maximum number of information bits for one stream when a particular modulation order is used for another stream. The UE may determine CQIs for multiple streams for the non-linear detector based on the at least one parameter. The UE may also select a precoding matrix (e.g., jointly with the CQIs) based on the at least one parameter. The UE may report the selected precoding matrix and the CQIs for the multiple streams. The UE may thereafter receive a transmission of the multiple streams, which may be transmitted based on the selected precoding matrix and the CQIs.Type: GrantFiled: October 22, 2010Date of Patent: September 3, 2013Assignee: QUALCOMM IncorporatedInventors: Yi Su, Jia Tang, Atul A.

Exploiting known rate matching information in blind decoding of downlink wireless data transmissions
Patent number: 8441981Abstract: In the processing of a data transmission received on wireless data channel HS-DSCH during HS-SCCH-less (HSL) operation according to 3GPP TS 25.214 V7.7.0, a situation is identified wherein redundancy version information corresponding to the received data transmission cannot be obtained from wireless control channel HS-SCCH. The redundancy version information is normally indicative of an HSL redundancy version that specifies derate matching for the received data transmission. In response to identification of the situation, derate matching is applied to the received data transmission according to an HSL redundancy version other than the HSL redundancy version that is specified by HSL for derate matching in the situation.Type: GrantFiled: February 14, 2008Date of Patent: May 14, 2013Assignee: QUALCOMM IncorporatedInventors: Jonathan Sidi, Shantanu Khare -
Publication number: 20130072250Abstract: A slot in a frame of n frames is received at user equipment (UE). Valid slots are detected based on a given validity criterion. The valid slots are classified as outage slots if an estimated signal quality does not exceed an outage signal quality. A total valid slot count and a total outage slot count are accumulated over an outer loop duration spanning a plurality of the slots. The total outage slot count is compared to a preset ratio of the total valid slot count. A target signal quality is updated based on the comparison.Type: ApplicationFiled: March 20, 2012Publication date: March 21, 2013Applicant: QUALCOMM IncorporatedInventors: Wei Zhang, Jittra Jootar, Kunal Srivastava, Guang Xie, Feng Lu, Jonathan Sidi

Patent number: 8149964Abstract: Techniques for scaling symbols to account for large abrupt changes in received power at a user equipment (UE) are described. The UE performs AGC on received samples to obtain input samples. The UE processes (e.g., CDMA demodulates) the input samples to obtain first symbols. The UE determines the power of the input samples and derives a symbol gain based on (e.g., inversely related to) the power of the input samples. The UE scales the first symbols with the symbol gain to obtain detected data symbols having approximately constant amplitude, even with large abrupt changes in the power of the input samples. The UE estimates signal amplitude and noise variance based on the detected data symbols, computes LLRs for code bits of the detected data symbols based on the signal amplitude and noise variance, and decodes the LLRs to obtain decoded data.Type: GrantFiled: June 25, 2007Date of Patent: April 3, 2012Assignee: QUALCOMM, IncorporatedInventors: Jonathan Sidi, Ketan N.
