Abstract: A method of continuously estimating barometric pressure values for use in an engine control system. The vehicle includes an manifold absolute pressure (MAP) sensor, ambient air temperature sensor and a throttle position sensor. The method comprises the steps of determining the manifold absolute pressure, ambient air temperature, and throttle position. When the throttle position is at wide-open throttle, the method generates a barometric pressure value ({circumflex over (P)}anew) as a function of the manifold absolute pressure value (P) and previously estimated barometric pressure. Otherwise, the method generates a barometric pressure value as a function of the manifold absolute pressure value (P), and an estimated intake manifold pressure ({circumflex over (P)}) and estimated mass airflow (). In a further embodiment, a mass airflow sensor is also used to generate the estimated barometric pressure value when the engine is not operating at wide-open throttle.

Abstract: A method for controlling a spark ignited direct injection internal combustion engine having an air intake with a throttle valve positioned therein and a plurality of cylinders operable in at least a homogeneous operating mode with a homogeneous air/fuel mixture and an associated range of allowable homogeneous air/fuel ratios and a stratified mode with a stratified air/fuel mixture and an associated range of allowable stratified air/fuel ratios, wherein the homogeneous range and stratified range do not overlap, includes determining a desired value for an engine operating parameter based on current engine operating conditions wherein the desired value results in scheduling of an air/fuel ratio between the homogeneous range and stratified range of allowable air/fuel ratios, operating a first portion of the cylinders in the homogenous operating mode, and operating a second portion of the cylinders in the stratified operating mode such that a combined air/fuel ratio associated with the first and second portions of the cylinders approaches the scheduled air/fuel ratio. The invention provides an additional degree of freedom in controlling a DISI engine without additional sensor/actuator cost and provides a hybrid operating mode which closes the gap between stratified and homogeneous operating modes.

Abstract: A method and system for controlling torque disturbances in direct injection stratified charge and lean burn port-fuel injection engines (12) through continuously variable transmission (40). The method and system include using the continuously variable transmission (40) to mitigate the effects of torque disturbances due to a lean NOx trap (22) purge cycle (100). The continuously variable transmission (40) is coordinated with other engine variables, such as throttle (36), fueling rate (Wf), injection timing (&ggr;), and spark timing (&dgr;), to keep the operation near the optimal regime. In periods of trap (22) purge, the engine control variables and the continuously variable transmission (40) are coordinated to maximize purge efficiency for a predetermined period of time. In periods of normal operation (102), the engine control variables and the continuously variable transmission (40) are coordinated to minimize fuel consumption subject to emission constraints.

Abstract: A method of wireless communication, by a user equipment (UE) includes receiving downlink semi-persistent scheduling (SPS) configurations. The method also includes receiving a physical downlink shared channel (PDSCH) transmission for each of the plurality of SPS configurations. Each PDSCH transmission has no associated physical downlink control channel (PDCCH). The method further includes determining whether successful decoding of each of the PDSCH transmissions occurred. The method further includes generating a hybrid automatic repeat request (HARQ) codebook for the PDSCH transmissions based on the determining. The method also includes transmitting the HARQ codebook in a physical uplink control channel (PUCCH) only when at least one ACK is present in the HARQ codebook.

Abstract: Downlink schemes are disclosed for a cooperative user equipment (UE) with joint baseband processing. UEs may establish a cooperative UE unit with one or more neighboring UEs, where one of the UEs operates as the primary UE. The participating UEs of the cooperative UE unit determine a downlink transmission scheme for the cooperative transmissions from a serving base station and receive cooperative transmissions of one or more transport blocks from the serving base station according to the downlink transmission scheme. The secondary UEs of the cooperative UE unit generate and transmit cooperative process data to the primary UE, where the cooperative process data is based on the receipt of the cooperative transmissions by the secondary UEs. The primary UE processes its received cooperative transmission along with the cooperative process data to decode the one or more transport blocks. Other aspects and features are also claimed and described.

Abstract: Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.
