Uplink Transmit Switch Scheduling for Carrier Aggregation

The patent implements dynamic RF chain allocation where the system can switch between different allocation modes: one RF chain per frequency band for inter-band carrier aggregation, or both RF chains to a single frequency band for intra-band carrier aggregation with multiple component carriers. This dynamic switching capability allows the system to adapt to different bandwidth requirements and frequency band conditions, optimizing productivity without permanently increasing device complexity.

The patent extends the uplink transmit switching preparation time to allow the device to perform blind decoding and identify multiple component carriers within a frequency band before making switching decisions. This preliminary action ensures that when switching is required, the device has already gathered necessary information about available component carriers, thereby improving bandwidth allocation efficiency while managing the switching time through advance preparation.

The patent implements dynamic RF chain allocation that allows switching between one RF chain per frequency band and both RF chains to a single frequency band based on current bandwidth requirements and thermal conditions. This dynamic approach enables the system to achieve high data rates when needed by concentrating both RF chains on a single band with multiple component carriers, while returning to the more energy-efficient one-RF-chain-per-band configuration when maximum data rates are not required, thus managing power consumption and thermal limitations.
