Patent number: 11589385Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request message to a base station while operating in an idle mode. The base station may generate, in response to the request message, a response message including a random access preamble index corresponding to the received request message. In some cases, the base station may determine a radio network temporary identifier (RNTI) based on the random access preamble index and scramble a cyclic redundancy check (CRC) of the response message with the RNTI. In some examples, the random access preamble index may be included in a payload of the response message. The UE may monitor a physical downlink control channel for the response message to the request message and receive the response message on the physical downlink control channel.Type: GrantFiled: November 12, 2021Date of Patent: February 21, 2023Assignee: QUALCOMM IncorporatedInventors: Sony Akkarakaran, Tao Luo, Keiichi Kubota

Patent number: 11582823Abstract: Methods, systems, and devices for wireless communications are described. One example method for wireless communications at a user equipment (UE) includes detecting a radio link failure (RLF) condition for a connection between the UE and a network over a first cell group and determining, in response to detecting the RLF condition, whether an air interface resource allocation is available for a signaling radio bearer (SRB) between the UE and the network over another cell group. The method also includes selecting, based at least in part on the determination, one of a plurality of RLF procedures. In some examples, the UE may select a first RLF procedure that fully releases radio resources when no SRB is available and a different, second RLF procedure that partially when an SRB is available between the UE and the network over a second cell group.Type: GrantFiled: April 13, 2020Date of Patent: February 14, 2023Assignee: QUALCOMM IncorporatedInventors: Yu-Ting Yu, Keiichi Kubota, Gavin Bernard Horn, Karthika Paladugu

Patent number: 11516142Abstract: A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.Type: GrantFiled: August 9, 2018Date of Patent: November 29, 2022Assignee: QUALCOMM IncorporatedInventors: Ruiming Zheng, Yu-Ting Yu, Keiichi Kubota, Gavin Bernard Horn

Patent number: 11477783Abstract: Systems and methods for enabling and providing uplink based mobility procedures are disclosed. Embodiments provide uplink based mobility procedures in which one or more physical channel typically used to facilitate uplink based mobility is not utilized. For example, an uplink based mobility process of embodiments utilizes a UL-based mobility specific ID and/or synchronization signals to provide information for decoding signals avoiding the use of physical cell identifier channel (PCICH). Embodiments of an uplink based mobility process utilize a physical channel, such as a physical slot format indication channel (PSFICH) or a physical downlink control channel (PDCCH), to provide uplink mobility signal acknowledgements and paging indications avoiding the use of a physical keep alive channel (PKACH).Type: GrantFiled: March 17, 2017Date of Patent: October 18, 2022Assignee: QUALCOMM IncorporatedInventors: Hung Ly, Heechoon Lee, Keiichi Kubota, Tingfang Ji

Patent number: 11476999Abstract: Techniques and apparatus for a control plane design for bandwidth part (BWP) in new radio (NR) are provided. One technique includes sending information with an indication of a BWP capability of a user equipment (UE) to a base station (BS). A configuration from the BS indicating a set of BWPs available to use for communication is received in response to the indication. Communications are performed on at least one of the set of BWPs. Another technique includes receiving information having an indication of a BWP capability of the UE. A configuration indicating a set of BWPs available for the UE to use for communication is determined. The configuration is sent to the UE.Type: GrantFiled: November 16, 2018Date of Patent: October 18, 2022Assignee: QUALCOMM IncorporatedInventors: Peng Cheng, Keiichi Kubota, Peter Pui Lok Ang, Linhai He

Publication number: 20220272595Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.Type: ApplicationFiled: March 7, 2022Publication date: August 25, 2022Inventors: Aleksandar Damnjanovic, Keiichi Kubota, Linhai He, Gavin Bernard Horn, Peng Cheng
