Patent number: 11979760Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.Type: GrantFiled: August 4, 2020Date of Patent: May 7, 2024Assignee: Apple Inc.Inventors: Weidong Yang, Amir Farajidana, Chunhai Yao, Chunxuan Ye, Dawei Zhang, Haitong Sun, Hong He, Jie Cui, Keith W.

Publication number: 20240107439Abstract: A system is configured for reconfiguration of a Synchronization Signal Block (SSB) pattern. The system is configured for obtaining data including a configuration for a Synchronization Signal Block (SSB) transmission carrying a physical broadcast channel (PBCH), the configuration specifying, for an SSB of the configuration, resource elements (REs) allocated for transmitting a primary synchronization signal (PSS) to a user equipment (UE) and REs allocated for transmitting a secondary synchronization signal (SSS) to the UE. The system is configured for selecting a set of REs that are unused in the configuration for the SSB transmission, specifying a filling sequence for extending a synchronization signal or an SSB to the set of REs that are unused in the configuration of the SSB transmission, generating data including an enhanced configuration for the SSB transmission that includes the extended synchronization signal or the extended SSBs, and transmitting the SSB transmission using the enhanced configuration.Type: ApplicationFiled: September 22, 2023Publication date: March 28, 2024Inventors: Yihong Qi, Amir Aminzadeh Gohari, Amir Farajidana, Dan Zhang, Herbert R.

Patent number: 8774816Abstract: A dynamic shared forward link channel (or “data” channel) is used to send multicast data to a group of wireless devices, e.g., using a common long code mask for the data channel. Reference power control (PC) bits are also sent on the data channel and used for signal quality estimation. A shared forward link control channel is used to send user-specific signaling to individual wireless devices, e.g., using time division multiplexing (TDM) and a unique long code mask for each wireless device. A shared forward link indicator channel is used to send reverse link (RL) PC bits to the wireless devices, e.g., using TDM. The data channel is jointly power controlled by all wireless devices receiving the data channel. The control and indicator channels are individually power controlled by each wireless device such that the signaling and RL PC bits sent on these channels for the wireless device are reliably received.Type: GrantFiled: June 4, 2010Date of Patent: July 8, 2014Assignee: QUALCOMM IncorporatedInventors: Tao Chen, Baaziz Achour, Brian K.

Patent number: 8085840Abstract: An apparatus for reducing interference of a signal over a plurality of stages includes a processor configured to determine at least two equalizer taps based on at least one of a covariance and a channel impulse response of the signal. The processor is further configured to estimate at least one additional equalizer tap based on the at least two equalizer taps. In addition, the processor is configured to reduce, for each of the plurality of stages, the interference of the signal for that stage using an equalizer tap from either the at least two equalizer taps or the at least one additional equalizer tap, so that the signal for the next stage in the plurality of stages has the reduced interference. A method is also provided for reducing interference of a signal over a plurality of stages.Type: GrantFiled: October 1, 2008Date of Patent: December 27, 2011Assignee: Qualcomm IncorporatedInventors: Keith W.

Publication number: 20100323747Abstract: A forward link power control mechanism measures the reverse link power control bits which are transmitted on the forward traffic channel. At the remote station, the reverse link power control bits from multiples base stations or multiple signal paths are measured, combined, and filtered to yield an improved measurement of the forward link signal quality. The reverse link power control bits which are deemed unreliable are omitted from use in the power control loop. The remote station generates a set of forward link power control bit in accordance with the measurements and transmits these bits to all base stations in communication with the remote station. Each base station adjusts its gain of the forward traffic channel in accordance to its measurement of the forward link power control bit.Type: ApplicationFiled: August 26, 2010Publication date: December 23, 2010Applicant: QUALCOMM IncorporatedInventors: Edward G.
