Patent number: 11671202Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.Type: GrantFiled: December 1, 2020Date of Patent: June 6, 2023Assignee: QUALCOMM IncorporatedInventors: Ahmed Omar Desouky Ali, Brian Clarke Banister, Supratik Bhattacharjee, Udayan Murli Bhawnani, Jittra Jootar, Timothy Paul Pals, Rebecca Wen-Ling Yuan, Arvind Vardarajan Santhanam, Zhibin Dang, Omesh Kumar Handa, Sibasish Das, Chetan Jagdeesh Bharadwaj, Gautham Hariharan, Min Wang, Farrukh Rashid, Nan Zhang, Sumanth Kumar Kota

Patent number: 11394433Abstract: Certain aspects of the present disclosure provide techniques for reducing a quantity of data sent carrier aggregation (CA) related capability reporting by a UE operating in a cell using full dimension multiple-input multiple-output (FD-MIMO) techniques. In an exemplary method, a base station obtains a relative weight of baseband processing for a component carrier (CC) configured for full-dimension multiple-input multiple-output (FD-MIMO) communications for a user equipment (UE); determines, based on the relative weight, to enable FD-MIMO downlink (DL) transmissions to the UE via the CC; and transmits an FD-MIMO transmission via the CC to the UE.Type: GrantFiled: March 16, 2020Date of Patent: July 19, 2022Assignee: QUALCOMM IncorporatedInventors: Timothy Paul Pals, Alberto Rico Alvarino, Amir Farajidana, Honey Kakkar, Parastoo Kheirkhah, Nitin Pant, Umesh Phuyal, Wenshu Zhang, Manish Jain

Patent number: 11374677Abstract: Methods, systems, and devices for wireless communications are described. More specifically, the methods, systems, and devices support extending capability signaling to support higher modulation order baseband capability, such as higher order quadrature amplitude modulation (QAM), for example, 1024QAM. By way of example, a user equipment (UE) may transmit UE capability information to a base station (e.g., eNodeB (eNB), next-generation NodeB ((gNB)) in a connection establishment procedure. The UE capability information may include a UE category identifier and a baseband capability parameter. The baseband capability parameter may indicate a scaling factor for a first modulation order of a plurality of available modulation orders. The UE may communicate with the base station over multiple layers using corresponding modulation orders for the multiple layers.Type: GrantFiled: March 31, 2020Date of Patent: June 28, 2022Assignee: QUALCOMM IncorporatedInventors: Wenshu Zhang, Amir Farajidana, Timothy Paul Pals, Alberto Rico Alvarino, Honey Kakkar, Parastoo Kheirkhah, Nitin Pant, Umesh Phuyal, Venkata Naga Aishwarya Reddy Kasa, Shashank Maiya

Patent number: 11297490Abstract: Aspects are provided which allow an apparatus to efficiently indicate downgraded band combinations associated with carrier aggregation (CA) to a base station, in which one or more UE capabilities such as the DL MIMO of certain supported band combinations may be downgraded in exchange for other UE capabilities such as FD-MIMO and 256/1024QAM. The apparatus, which may be a UE, receives a request from a base station for information associated with downgraded band combinations and for information corresponding to at least one UE capability associated with each of the downgraded band combinations. After receiving the request, the UE sends, to the base station, information indicating the downgraded band combinations and the at least one UE capability. The UE may thus report downgraded band combinations for a subset of supported band combinations as requested by the base station, thereby minimizing capability reporting of the UE.Type: GrantFiled: February 21, 2020Date of Patent: April 5, 2022Assignee: QUALCOMM IncorporatedInventors: Timothy Paul Pals, Alberto Rico Alvarino, Amir Farajidana, Honey Kakkar, Parastoo Kheirkhah, Nitin Pant, Umesh Phuyal, Wenshu Zhang

Patent number: 10044478Abstract: The present disclosure relates to pseudo-randomization of unused resources at a medium access control layer (MAC) of a user equipment (UE). For example, the disclosure presents a method and an apparatus for determining that an uplink (UL) resource grant, associated with a first radio access technology (RAT), for the UE results in unused resources where there are a greater number of resources than available data for transmission at the UE, wherein the UE is configured to receive information associated with a second RAT, and wherein the first RAT is different from the second RAT, populating the unused resources, at a medium access control (MAC) layer, with pseudo-randomized bits, and transmitting at least a portion of the available data and the populated unused resources using the UL resource grant associated with the first RAT. As such, pseudo-randomization of unused resources at a medium access control layer (MAC) of a UE may be achieved.Type: GrantFiled: July 9, 2015Date of Patent: August 7, 2018Assignee: QUALCOMM IncorporatedInventors: Amit Gopilal Jain, Emilija Milorad Simic, Bao Vinh Nguyen, Dominic Gerard Farmer, Arif Ehsan, Dinesh Subramani, Duong Anh Hoang, Timothy Paul Pals

Patent number: 9304209Abstract: Methods and systems for evaluating Global Navigation Satellite System (GNSS) signals are provided. Each of a first GNSS signal received by a GNSS receiver and a second GNSS signal received by the GNSS receiver is accessed. The second GNSS signal can have temporal fluctuations weaker than temporal fluctuations in the first GNSS signal. A delay between a sequence in the first GNSS signal and a corresponding sequence signal in the second GNSS signal is estimated and compared to a threshold. Upon determining that the delay exceeds the threshold, a location is estimated using both the first GNSS signal and the second GNSS signal.Type: GrantFiled: March 13, 2013Date of Patent: April 5, 2016Assignee: QUALCOMM IncorporatedInventors: Duong Anh Hoang, Emilija Milorad Simic, Timothy Paul Pals
