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: 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 for resuming the PS/CS call with the network, in response to identifying that the data inactivity was due to the radio link failure.

Abstract: Apparatuses, systems, and methods to avoid contact/identity disclosure when using a multiple subscriber identity module (multi-SIM) wireless electronic device are described. According to one method, if a call to a first party in a first SIM cannot be established using the first SIM, the call is established using a second SIM, but without the device displaying identity/contact information of the first SIM. According to the embodiment, the calling line identification restriction (CLIR) supplementary service may be used, a user-to-user signalling (UUS) service may be invoked, and/or the user may decide to share selected identity/contact information associated with the first SIM while withholding the rest from the device.
