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.

說明書

Referring to FIG. 5A, the UE 300 at the first location 430a maintains a clear line of site with the eNB 102 and a distance between the UE 300 and the eNB 102 is shorter when the UE 300 is located at the first location 430a than when the UE 300 is located at the second location 430b (FIG. 5B). Here, the CC-KPI log 550 indicates that the expected KPIs 450, 450a at the first location 430a for the both the first and second component carriers CC1, CC2 are high. For instance, the first CC1 includes a RANK and SINR of 3.7 and 33 dB, respectively, and the second CC2 includes a corresponding RANK and SINR of 3.2 and 31 dB, respectively. Assuming for example that the UE 300 has a total of six transceiver resources 310 available, the UE 300 may allocate four resources to the first CC1 to support a 4×4 MIMO configuration to maximize throughput on the high frequency band and allocate two resources to the CC2 to support a 2×2 MIMO configuration on the low frequency band.
