Latest Patents

Carrier Aggregation Method, Apparatus, and System. This invention describes how a terminal device handles activated serving cells configured across at least two frequency bands. The terminal identifies a reference cell in each band and determines transmission directions for the activated cells, with the reference cell and other cells in the same band sharing the same transmission direction.

Communication Method and Communication Apparatus. This invention concerns determining a candidate physical downlink shared channel (PDSCH) reception occasion from a time-frequency resource and forming a hybrid automatic repeat request acknowledgment (HARQ-ACK) codebook. The terminal sends the codebook to a network device. The method accounts for a resource spanning consecutive, non-overlapping subbands where symbols may have different categories across those subbands.
