Data communication method, wireless communication system, and base station

摘要

The invention provides a wireless communication system. In one embodiment, the wireless communication system comprises a base station and user equipment. The base station transmits data to user equipment via a plurality of the component carriers comprising a series of data transmission cycles, interleaves starting time of a plurality of active periods of the component carriers in each data transmission cycle in an order, and sends control data to the user equipment via the component carriers during the active periods of the component carriers. The user equipment receives the control data via the component carriers during the active periods of the component carriers.

1. A data communication method for a wireless communication system, wherein the wireless communication system comprises a base station and user equipment, the base station transmits data to the user equipment via a plurality of the component carriers comprising a series of data transmission cycles, and the method comprises:
interleaving starting times of a plurality of active periods of the component carriers in each data transmission cycle, wherein the component carriers with the interleaved starting times of the plurality of active periods are transmitted from the base station to the same one user equipment, wherein the interleaved starting times are non-overlapping through an offset period; sending control data from the base station to the user equipment via the component carriers during the active periods of the component carriers; and sending an activation signal from the base station to the user equipment via an active period of an early activated component carrier to adjust the starting time and the duration of each of the active periods of at least one later-activated component carrier in some of the data transmission cycles, wherein the starting time of the active period of the early activated component carrier is earlier than that of the later-activated component carrier, wherein only one active period is present within each data transmission cycle of the early activated component carrier and within each data transmission cycle of the at least one later-activated component carrier, wherein the early activated component carrier and the at least one later-activated component carrier all have different carrier frequencies.
