TDD operation in wireless communication systems |
| 摘要 |
A method provides a wireless frame protocol. The method includes communicating a transmission interval that facilitates switching between a downlink portion and an uplink portion of a wireless communications channel. The method employs one or more guard periods during the transmission interval to mitigate overlap of transmitting frequencies between the downlink and uplink portions of the wireless communications channel. |

1. A method to provide a wireless protocol, comprising:
communicating a transmission interval that facilitates switching between a downlink portion and an uplink portion of a wireless communications channel; and employing one or more guard periods during the transmission interval to mitigate overlap of transmitting frequencies between the downlink and uplink portions of the wireless communications channel, wherein the one or more guard periods include at least one downlink pilot transmission structure (DwPTS), wherein the at least one DwPTS includes a control portion, and wherein the control portion is followed by a first synchronization signal and preceded by a second synchronization signal. |
