Patent number: 9408165Abstract: Techniques to increase capacity in a wireless communications system. In an aspect, systematic non-transmission, or “blanking,” of minimal-rate frames transmitted in a communications system is provided. In an exemplary embodiment, eighth rate frames in a cdma2000 voice communications system are systematically substituted with null-rate frames carrying zero traffic bits.

Patent number: 9408217Abstract: Techniques for determining power relaxation values are disclosed. The power relaxation values may be determined according to an ending resource block (RB) and a number of RBs in a contiguous allocation. In one aspect, the power relaxation values are arranged into regions based, at least in part, on transmission channel bandwidths and the distance from a protected adjacent channel. A user equipment (UE) can determine a power relaxation value for its current allocation using the ending RB index and contiguous RB length and can adjust its transmission power accordingly. Evolved NodeBs may estimate the power relaxation that a particular UE has selected in order to more accurately determine the transmit power available to the UE. Using the more accurate estimate of transmit power, the eNB may schedule the UE for uplink transmissions accordingly.Type: GrantFiled: January 16, 2013Date of Patent: August 2, 2016Assignee: QUALCOMM IncorporatedInventors: Tingfang Ji, Peter Gaal, William R.

Patent number: 9406132Abstract: In general, techniques are described for determining a vision-based quality metric for three-dimensional (3D) video. A device (12, 14) comprising a 3D analysis unit (24, 48) may implement these techniques to compute a 3D objective metric (36, 60). The 3D analysis unit (24, 48) estimates an ideal depth map (62, 70) that would generate a distortion limited image view using DIBR-based 3D video data (34) and then derives one or more distortion metrics (64, 72) based on quantitative comparison of the ideal depth map (62, 70) and a depth map (28, 58) used in the generation of the DIBR-based 3D video data (34). Based on the derived one or more distortion metrics (64, 72), the 3D analysis unit (24, 48) computes the objective metric (36, 60) to quantify visual quality of DIBR-based video data (34). The 3D objective metric (36, 60) may be used to alter or otherwise adjust depth estimation and encoding/decoding parameters to correct for expected visual discomfort.Type: GrantFiled: April 26, 2011Date of Patent: August 2, 2016Assignee: QUALCOMM IncorporatedInventors: Judit Martinez Bauza, Mashhour M.

Patent number: 9408156Abstract: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power “steps” that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.Type: GrantFiled: July 19, 2013Date of Patent: August 2, 2016Assignee: QUALCOMM IncorporatedInventors: Wanshi Chen, Juan Montojo, Arnaud Meylan
