Abstract: Methods, systems, and devices related to the management of bandwidth parts (BWPs) by a user equipment (UE) or a base station are disclosed. In one exemplary aspect, a method for wireless communication includes establishing, at a mobile device, a network connection with a first cell; receiving, at a mobile device, a message indicating an activation of a second cell and a first bandwidth part to be used by the mobile device upon the activation of the second cell, wherein a bandwidth part represents a logical grouping of frequency bandwidth of a cell; performing, based on the message, a random access process with the second cell using the first bandwidth part; and switching to a second bandwidth part of the second cell when the random access process fails.

Abstract: The embodiments of the present document propose a method and apparatus for reporting and receiving a buffer status. The method includes: when a terminal judges that there is a split bearer or receives a notification transmitted by a base station that an additional buffer report is required to be reported, the terminal transmitting a Buffer Status Report (BSR) of the radio bearer to the base station; herein the BSR carries size information about buffer data and size information about additional buffer data of the radio bearer. The embodiments of the present document realize the reporting of a buffer status when there is a split bearer.

Abstract: The disclosure discloses a reporting method, device and system for a Power Headroom Report (PHR) in dual connectivity. A first Evolved Node B (eNB) and a second eNB establish split Data Radio Bearers (DRBs) with a User Equipment (UE), and transmit an indication for indicating change in uplink transmission to the UE; the UE determines the change in the uplink transmission of the split DRBs, and triggers and reports the PHR to the first eNB and/or the second eNB according to the change in the uplink transmission respectively; and the first eNB and/or the second eNB receive/receives the PHR reported by the UE respectively. The disclosure also discloses the reporting device and system for the PHR in the dual connectivity.
