METHOD AND APPARATUS FOR TRANSMITTING CONTROL INFORMATION VIA UPPER LAYER

摘要

Techniques for supporting communication for wireless devices in a wireless network are described. The wireless network may support transmission of control information on a first physical channel having a first minimum SNR for reliable reception. Some wireless devices may require operation at a lower SNR. In an aspect, low SNR operation may be supported by transmitting control information for a lower layer (e.g., Layer 1 or 2) in a protocol stack via an upper layer (e.g., Layer 3) in the protocol stack. This transmission scheme may allow the control information to be transmitted on a second physical channel instead of the first physical channel normally used to transmit the control information. The second physical channel may have a lower minimum SNR than the first minimum SNR. This transmission scheme may also allow the control information to be transmitted multiple times to improve reliability.
