  Development of 5G Traffic control features in Ericsson Projects Project 4: DCI Based BWP Switch Search Space Adaptation Enhancement This project supports new TDD pattern 4DL+3UL+2DL+1UL. This pattern has more available UL slots and thereby more BWP switching behavior. Hence it gives improved performance of UE power saving. Project 3: NR FR1 BWP Preparation for Commercial This project provides functionality to support multiple BWP in a cell for FDD cells configured with either 30 or 40 MHz bandwidths. In addition to full BWP 30/40 MHz, the cell is configured with a second BWP of 20 MHz which can be used for UEs with only 20 MHz capability Project 2: DCI Based BWP Switch Search Space Adaptation This project is to support DCI based BWP switching for search space adaption for the purpose of UE power saving for TDD FR1. Multiple BWPs are configured. DCI based BWP switching is used to change the search space configurations in BWPs by configuring different slot/symbol monitoring pattern in different BWPs and switching BWP based on data/scheduling activities Project 1: A-MPR For CBRS in NR This project introduces support for A-MPR, which is mandatory for Citizen Broadband Radio Service (CBRS) deployments to meet specific regulatory emission requirements. A-MPR is enabled by indicating a frequency band specific NS-value to the UE, in either SIB1 or in RRC-configuration. The UE will then apply additional max-power back-off in uplink accordingly, and the maximum allowed back-off will be specific for each individual uplink transmission. Show less

  Worked in Cisco Projects LTE MME Project 3: Development and Sustenance of Ducon NSA To provide solution to customer found issues, feature enhancements and handling queries. • Worked on design and development of E-RAB Modification Indication collision scenarios • Worked on bug fixing for issues reported in Ducon NSA by customers • Supported customer queries / cases on day-to-day basis Project 2: Development and Sustenance of MME (EPC) To provide solution to customer found issues, feature enhancements and handling queries. • Worked on design and development of SRVCC collision scenarios • Worked on bug fixing for issues reported in SRVCC, Handover Cancel and collision scenarios. • Supported customer queries / cases on day-to-day basis Project 1: GTP Error Indication Error Indication is a tunnel management message to handle error scenarios. If eNB receives a GTP packet for an invalid TEID, then eNB must initiate Error Indication to the originating node. Similarly, if SGW sends Error Indication to eNB, it has to handle Error Indication by releasing the bearer associated with the tunnel id received in Error Indication message. This development is done with respect to eNB. Show less

  Worked in LTE domain, in L2- L3 layer, FAPI. Project 4: LTE to provide FAPI in eNB stack for TDD Development of eNB FAPI for TDD, with the existing MAC PHY interface. FAPI is an interface between MAC and PHY for communication. The physical interface used for communication between MAC and PHY is Giga bit Ethernet. The chosen configuration was Configuration 1 and Special Subframe configuration was 3 for TDD. Handled both downlink and uplink messages Project 3: Sustenance of eNB Stack To provide solution to customer found issues, feature enhancements and handling queries. Project 2: LTE S1AP to initiate and handle error scenarios Development of initiation of Error indication procedure and handling of Error indication at eNB S1AP module. Three types of errors are detected. They are Abstract Syntax Error, Logical Error and APID Error. At present handling Logical and APID error. Logical errors are detected when received message is not compatible with the receiver state or has semantic error. APID errors are detected when remote APID present in the received message is unknown or duplicated.

  Worked in LTE domain. Project: LTE GERAN to provide GSM stack for LTE network. This project supports CS fallback. The CS Fallback function uses the SGs interface to transfer the mobile terminating call requests from the CS domain to LTE. It also provides combined mobility management between GERAN and LTE.
