摘要

Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for configuring, transmitting, and receiving configured grant uplink transmissions. Other embodiments may be described and claimed.

說明書

A UE reception may be established by and via the one or more antenna panels 175, RFFE 165, RF circuitry 155, receive circuitry 145, digital baseband circuitry 125, and protocol processing circuitry 115. The one or more antenna panels 175 may receive a transmission from the AN 110 by receive-beamforming signals received by a plurality of antennas/antenna elements of the one or more antenna panels 175. Further details regarding the UE 105 architecture are illustrated in FIGS. 2 and 7-8. The transmission from the AN 110 may be transmit-beamformed by antennas of the AN 110. In some embodiments, the baseband circuitry 125 may contain both the transmit circuitry 135 and the receive circuitry 145. In other embodiments, the baseband circuitry 125 may be implemented in separate chips or modules, for example, one chip including the transmit circuitry 135 and another chip including the receive circuitry 145.

Similar to the UE 105, the AN 110 may include mmWave/sub-mmWave communication circuitry grouped according to functions. The AN 110 may include protocol processing circuitry 120, digital baseband circuitry 130 (or simply, “baseband circuitry 130”), transmit circuitry 140, receive circuitry 150, RF circuitry 160, RFFE 170, and one or more antenna panels 180.

A UL and/or DL transmission may be established by and via the protocol processing circuitry 120, digital baseband circuitry 130, transmit circuitry 140, RF circuitry 160, RFFE 170, and one or more antenna panels 180. The one or more antenna panels 180 may transmit a signal by forming a transmit beam and or receive a signal by forming a receiving beam.
