Abstract: A method and an apparatus are provided for receiving resource allocation information by a user equipment (UE) in a wireless communication system. Channel state information (CSI) is transmitted to a first base station. The resource allocation information indicating resources for a first zone to the UE is received from the first base station, when the UE enters the first zone among a plurality of zones within a cell coverage of the first base station. Additional resource allocation information indicating additional resources for a second zone are received from a second base station, if it is estimated that the UE might enter the second zone among the plurality of zones based on a status of the second zone and a moving direction of the UE. The additional resources are received in response to a message, transmitted from the first base station, to the second base station, requesting the additional resources.

Abstract: Systems and methods are described for positioning a Low Altitude Platform Station (LAPS) based drone cells for supporting communication in a 3GPP network. The methods may include receiving at least one feedback parameter from a UE pertaining to a current network traffic flow and mobility with respect of the UE. The UE is selected for an aerial network through a drone base station (DBS) cell based on service requirement determined from the feedback parameter. Further, a position for at least one DBS-cell is determined with respect to the at least one selected UE based on the at least one parameter to serve the selected UE. An aerial-communication link is established between the selected UE and the DBS cell by deploying one or more LAPS as a drone base station (DBS) in accordance with the determined position of DBS-cell to thereby augment a network connectivity of the selected UE.

Abstract: Embodiments herein provide a method for handling communication with a wireless network by a user equipment (UE). The method includes determining that a data inactivity timer has expired during a PS/CS call recovery procedure with a network. The method identifies whether data inactivity that caused the data inactivity timer to expire is due to a radio link failure with the network. A radio link is recovered through the recovery procedure tor resuming the PS/CS call with the network, in response to identifying that the data inactivity was due to the radio link failure.

Abstract: A method for managing an extended Discontinuous Reception (eDRX) in a User Equipment (UE) including determining, by the UE, as to whether an eDRX enablement avoidance criterion is met, and causing, by the UE, to stop sending a request message, which is configured to enable the eDRX, to a network entity when the eDRX enablement avoidance criterion is met. The eDRX enablement avoidance criterion may include one of a data transmission pattern, a historic eDRX usage pattern, whether a configurable retry timer is deactivated, whether a number attempts made to enable the eDRX exceeds a threshold, whether a number of attempts made to enable and disable the eDRX exceeds a threshold, whether a request accept message including an indication that eDRX is not supported, is received from the network entity, or whether an indication of no eDRX support is received from the network entity may be provided.

Abstract: Methods and apparatuses are provided for preserving a Radio Resource Control (RRC) state of a User Equipment (UE). The UE receives, from a radio network controller, a physical channel reconfiguration message for transitioning the RRC state of the UE. ACircuit Switching (CS) event is detected at the UE. A physical channel reconfiguration failure message associated with a failure cause to preserve the RRC state of the UE, is transmitted from the UE to the radio network controller.

Abstract: A method of optimizing connection mode procedures for a dual subscriber identity module (SIM) mobile communication device is provided. The method includes receiving, by a base station, a paging message for a first SIM in an idle mode from a core network; determining, by the base station, if a radio resource control (RRC) connection linked with the first SIM is available or not; triggering, by the base station, a second paging type message for the first SIM with a normal cause through the RRC connection linked with the first SIM if the RRC connection of the first SIM is available; determining, by the base station, if a RRC connection linked with a second SIM is available or not if the RRC connection of the first SIM is not available; triggering, by the base station, a second paging type message for the first SIM with a mapped new cause through the RRC connection linked with the second SIM if the second SIM is available; and triggering, by the base station, a first paging type message with a temporary identity and a cause received in the paging message from the core network through a paging channel if the RRC connection linked with the second SIM is not available.
