摘要

A method for allocating available transceiver resources across different component carriers (CC) includes obtaining a carrier aggregation capability that includes a list of available CCs supported by the UE at a current location for simultaneous communication with a carrier aggregation capable network. The method also includes, for each of the available CCs, obtaining an expected key performance indicator (KPI) associated with the corresponding available CC at the current location. The method also includes allocating the available transceiver resources across the available CCs based on the expected KPIs at the current location.

說(shuō)明書(shū)

In some examples, the available transceiver resources includes a total number of radio frequency (RF) chains of a RF front end of the UE. In this example, the total number of RF chains may include six RF chains. Additionally or alternatively, the available transceiver resources may include available baseband resources associated with multiple-input multiple-output (MIMO) processing and turbo decoding. In some configurations, the current location of the UE includes a physical location of the UE provided by global positioning system (GPS) coordinates and/or global navigation satellite system (GNSS) coordinates.

In some examples, after allocating the available transceiver resources to the available CCs, the method includes transmitting an allocation message from the UE to at least one base station of the carrier aggregation capable network. In these examples, the allocation message indicates the allocation of the available transceiver resources to the available CCs. After transmitting the allocation message to the at least one base station, the method may further include operating, by the data processing hardware, the UE in a carrier aggregation-mode by connecting the UE to each of the available CCs for simultaneous communication with the carrier aggregation capable network via the at least one base station. The UE may support a multiple-input multiple-output (MIMO) antenna configuration on at least one of the CCs. The MIMO antenna configuration supported by the UE on the corresponding CC may include a 2×2 MIMO antenna configuration or a 4×4 MIMO antenna configuration based on the number of transceiver resources allocated to the corresponding CC.
