Embodiment Construction

[0056] figure 1 The main components of the wireless telecommunications network 10 are shown schematically. In the illustrated UMTS network architecture, user equipment 50 roams through the wireless telecommunication system. A base station 20 is provided for supporting an electrical coverage area 30 . A plurality of such base stations 20 are provided and geographically distributed so as to provide wide area coverage to user equipment 50 .

[0057] When the user equipment is in the area 30 served by the base station, communication can be established between the user equipment and the base station over an associated radio link. Typically, each base station supports multiple sectors within geographic service area 30 .

[0058] Typically, a different antenna within a base station supports each associated sector. Each base station 20 has multiple antennas. It is important to understand that figure 1 Shown is a small set out of the total number of user equipment and base statio...

Abstract

Method, computer program product, and user equipment operable to perform the method for transmitting an uplink buffer status indication of a user equipment in a wireless communication network, in which the user equipment is configured to use dual The connectivity technology communicates with one or more base stations. The method includes: receiving an indication of a dual connectivity configuration to be used by the user equipment for uplink transmission; according to the received indication of the dual connectivity configuration, constructing an uplink buffer status report by the user equipment to be used by the user equipment according to the indication The one or more schedulers employed by the user equipment group the uplink buffer status; and transmit the constructed uplink buffer status report to the one or more base stations. Various aspects and embodiments provide methods for providing buffer status reporting in a network providing dual connectivity functionality according to which user equipment is served by a plurality of independent schedulers that are accessible via Non-ideal backhaul link connection.

Description

technical field [0001] The present invention relates to a method of transmitting an indication of a user equipment uplink buffer status in a wireless communication network, a computer program product and a user equipment operable to perform the method, in which the user equipment is configured to use dual connectivity technology to communicate with one or more base stations; Background technique [0002] Wireless telecommunication systems are well known. In these systems, a mobile communication device (eg, a mobile phone) is operable to communicate with a base station provided by a network provider. [0003] In known wireless telecommunication systems, radio coverage is provided for network-connectable devices, such as mobile phones, or wireless devices such as iPads or other tablets, in areas called cells. Typically, network-connectable devices in each cell are operable to receive information and data from and transmit information and data to the base station. [0004] T...
