Method and apparatus for unlicensed band operation

摘要

A method, apparatus and computer program product are provided in order to enable operation of both cellular and WLAN on a shared unlicensed band. In this regard, a method is provided that includes causing a primary transmission mode period of operation, a secondary transmission mode period of operation, and an idle mode period of operation on an unlicensed frequency band to be transmitted to a mobile terminal. The method further includes receiving an interfered ratio report from the mobile terminal. The method also includes causing the mobile terminal to be classified as at least one of a primary user or a secondary user based on the interfered ratio report. The method also includes causing the classification to be transmitted to the mobile terminal.

1. A method for operating a mobile terminal comprising:
receiving by the mobile terminal an operation mode indication from a network, wherein the operation mode indication comprises an indication of a primary transmission mode period of operation during which the mobile terminal operates without need for interference coordination, by the network with other users operating under the network, on an unlicensed frequency band, a secondary transmission mode period of operation during which the mobile terminal operates on predefined resources on the unlicensed frequency band, and an idle transmission mode period of operation during which the mobile terminal is not allowed to conduct any transmissions on the unlicensed frequency band; causing an interfered ratio report to be transmitted to the network, wherein the interfered ratio report is calculated as a total number of interfered symbols over a sensing period; determining whether to operate the mobile terminal as a primary user or a secondary user based on the interfered ratio report, wherein the primary user is configured to operate during the primary transmission mode period of operation and/or during the secondary transmission mode period of operation, and the secondary user is configured to operate during the secondary transmission mode period of operation only; and determining whether to operate the mobile terminal during the primary transmission mode period of operation, the secondary transmission mode period of operation, or the idle transmission mode period of operation.
