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

Each RF chain 310Ra-n of the RFIC 306 may be associated with a corresponding antenna of the antenna array 308 and include corresponding receiver circuitry (i.e., receiver RF chain) and corresponding transmitter circuitry (i.e., transmitter RF chain) for performing corresponding transmit/receive functions across a corresponding CC 220. The transmit circuitry and receive circuitry may be separate circuitry from one another or the corresponding RF chain may include circuitry that combines the transmit/receive functions. The number of transmitter RF chains and receiver RF chains may provide N×M MIMO antenna configurations where N(≥1) is the number of transmitter RF chains and M (≥2) is the number of receiver RF chains. The receiver circuitry and transmitter circuitry of each RF chain 310Ra-n may include, without limitation, low noise amplifiers (LNA), down converters, filters, variable gain amplifiers (VGA), analog-to-digital converters (ADC), digital-to-analog converters (DAC), or power amplifiers (PA). The ADC/DAC outputs/inputs associated with each RF chain 310Ra-n may be processed by a corresponding baseband resource 310Ba-n of the baseband IC 304. Each baseband resource 310Ba-n may be configured to perform MIMO processing, turbo decoding, and/or other digital signal-processing algorithms for signal reception and recovery. In the example shown, the number of baseband resources 310Ba-n is equal to the number of RF chains 310Ra-n. Accordingly, each transceiver resource 310 may collectively refer to a corresponding baseband resource/RF chain pair or may individually refer to either a corresponding baseband resource or a corresponding RF chain.
