Patent number: 10028254Abstract: Aspects of the present disclosure generally relate to managing decoding of system information blocks (SIBs) at a user equipment (UE) and managing SIB transmissions at a base station. For example, the described aspects at the UE may include detecting a trigger event for decoding one or more SIBs received from a cell and determining to avoid decoding of at least one SIB received from the cell in response to the detected trigger event and a mobility pattern of the UE. The described aspect at the UE may further include using a stored version of the at least one SIB for communication with the first cell.Type: GrantFiled: December 13, 2016Date of Patent: July 17, 2018Assignee: QUALCOMM IncorporatedInventors: Sumanth Kumar Kota, Krishna Rekhani, Sivasubramanian Ramalingam, Sathish Krishnamoorthy

Patent number: 9686736Abstract: In various aspects, the disclosure provides user equipment (UE) capable of conducting a public land mobile network (PLMN) search by determining a paging schedule for a serving cell of the UE, the serving cell being associated with a first PLMN and the paging schedule defining one or more paging occasions. The UE may initiate a search for a second PLMN between consecutive paging occasions, and may read information blocks on a broadcast channel of a cell of the second PLMN. The UE may discontinue reading a partially-read information block when the partially-read information block is scheduled for transmission at least partially concurrently with a paging occasion on the serving cell if the partially-read information block does not include information for identifying the second PLMN. The UE may ignore the first paging occasion when the partially-read information block includes the information for identifying the second PLMN.Type: GrantFiled: July 3, 2014Date of Patent: June 20, 2017Assignee: QUALCOMM IncorporatedInventors: Chaitanya Baratam, Sivasubramanian Ramalingam, Vikas Gulati, Girish Valluru, Sathish Krishnamoorthy, Satish Pavan Kumar Nichanametla

Publication number: 20160242072Abstract: Methods, systems, and devices are described for handling over-sized call setup messages are disclosed. A user equipment (UE) may identify the size of a connection setup message (e.g., RRC connection setup complete message) associated with one or more UE capability information. Based on the identified size of the connection setup message, the UE may determine an estimated time required to transmit the connection setup message to a network entity (e.g., base station) over at least one uplink channel and determine whether the estimated time is above or below a threshold. If the UE determines that the estimated time to transmit the connection setup message is greater than the threshold, the UE may remove at least a portion of the connection setup message and transmit a modified connection setup message.Type: ApplicationFiled: August 20, 2015Publication date: August 18, 2016Inventors: Liangchi Hsu, Sitaramanjaneyulu Kanamarlapudi, Sivasubramanian Ramalingam, Yongsheng Shi, Vikas Gulati, Sathish Krishnamoorthy

Patent number: 9210725Abstract: The present disclosure presents a method and apparatus for improving uplink (UL) performance at a user equipment (UE). For example, the method may include identifying a random access channel (RACH) preamble failure when the UE is communicating with a current serving cell of the UE, increasing transmission power of successive RACH preambles based at least on the identifying, comparing signals received on a downlink at the UE via a first path and a second path from the current serving cell of the UE, and determining that a RACH preamble failure problem exists at the UE based at least on the comparing of the signals received on the downlink and identifying of successive RACH preamble failures. As such, improved performance uplink (UL) performance at a UE may be achieved.Type: GrantFiled: May 23, 2014Date of Patent: December 8, 2015Assignee: QUALCOMM IncorporatedInventors: Sitaramanjaneyulu Kanamarlapudi, Sivasubramanian Ramalingam, Liangchi Hsu, Hemanth Kumar Rayapati

Publication number: 20150146627Abstract: The disclosure provides methods and apparatus to improve public land mobile network search time. A user equipment (UE) may determine a subset of channels within a frequency band based on a stored identifier of a channel used by a previously acquired cell, each channel in the subset being spaced from the channel used by the previously acquired cell by a different multiple of a set spacing, the set spacing being greater than a spacing between adjacent channels. The subset of channels may be scanned to determine a signal strength of each channel in the subset. The UE may rank each channel in the subset according to the determined signal strength of the channel and attempt to acquire a cell using a channel in the subset based on the ranking.Type: ApplicationFiled: April 25, 2014Publication date: May 28, 2015Applicant: QUALCOMM IncorporatedInventors: Manjunatha Subbamma ANANDA, Pankaj BANSAL, Siddhant MEHROTRA, Sivasubramanian RAMALINGAM
