Apple patents phone antenna tech to send data on two beams at once
Apple has filed a patent for a method that allows a device to use two different antenna panels simultaneously for uplink transmissions. The system receives specific instructions to apply distinct beam configurations to each panel, enabling the device to send data using two separate directional signals at the same time.
In the filing’s own words
Disclosed are methods, systems, and computer-readable medium to perform operations including: receiving downlink control information (DCI) scheduling a first physical uplink shared channel (PUSCH) transmission to be transmitted by a first antenna panel of the UE, and a second PUSCH transmission to be transmitted by a second antenna panel of the UE, receiving data indicative of at least two transmission configuration indicator (TCI) states, the at least two TCI states including a first TCI state indicating a beam of the first antenna panel for transmission of the first PUSCH transmission, and a second TCI state indicating a beam of the second antenna panel for transmission of the second PUSCH transmission, and transmitting the first PUSCH transmission using the beam of the first antenna panel and the second PUSCH transmission using the beam of the second antenna panel.
What exactly they claim (claim 1)
1. An apparatus comprising one or more baseband processors configured to perform operations comprising: receiving data indicating a first transmission configuration indicator (TCI) state and a second TCI state; receiving downlink control information (DCI) scheduling at least one physical uplink shared channel (PUSCH) transmission, wherein the DCI comprises a sounding reference signal (SRS) resource set indicator field, and wherein a value of the SRS resource set indicator field indicates that the first TCI state is to be applied to one or more antenna ports associated with a first SRS resource set, and the second TCI state is to be applied to one or more antenna ports associated with a second SRS resource set; and transmitting, in accordance with the SRS resource set indicator field, the at least one PUSCH transmission.
