SYSTEMS AND METHODS FOR IMPROVING UPLINK TRANSMISSION PROPERTIES IN A COMMUNICATION NETWORK

摘要

Embodiments are directed to improving uplink transmission properties in a communication network. In one aspect a method for improving uplink transmission properties is disclosed that includes: obtaining information indicating an operating scenario of a UE, wherein the UE includes a plurality of antennas and the UE is configured to transmit UL signals using the plurality of antennas; selecting a precoder that is optimized for UL multiple antenna transmission based on at least the indicated operating scenario; and communicating the precoder to the UE. The information indicating an operating scenario comprises information indicating one or more of: i) a deployment characteristic on which the UE operates, ii) a cell change scenario, iii) a radio transmission characteristic of the UE, iv) a number of links that are involved in UL transmissions from the UE, and v) a type of service used by the UE.
