摘要:
Systems and methods are provided for adaptively transmitting information to a plurality of nodes in a local area of a base station. The base station receives channel quality information from one or more of the nodes within the local area, selects a transmission rate for a downlink transmission corresponding to the lowest channel qualities, and simultaneously transmits a message to the nodes at the selected transmission rate.

Techniques for supporting communication for wireless devices in a wireless network are described. The wireless network may support 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 data on a second physical channel that can be reliably received at a second minimum SNR that is lower than the first minimum SNR. In another aspect, low SNR operation may be supported by transmitting data on both the first and second physical channels. In yet another aspect, low SNR operation may be supported by transmitting data in multiple instances of the first and/or second physical channel. In yet another aspect, low power operation may be supported by transmitting the second physical channel in a portion of the system bandwidth instead of across the entire system bandwidth.
摘要:
Certain aspects of the present disclosure provide methods, apparatus, and computer-program products for the detection of potentially interfering user equipment (UE) in the proximity of a detecting entity. The detecting entity may be a base station or a UE. The detecting entity may take one or more actions in response to the detection in an effort to mitigate interference.
摘要:
Systems, methods and apparatuses are provided that facilitate selecting resources, such as time slots, subframes, etc., for performing bandwidth switching related to activating and/or deactivating one or more carriers. A data portion of one or more subframes can be selected for performing bandwidth switching. In addition, a device can determine whether one or more downlink grants are received in the one or more subframes, and can avoid selecting such subframes. The device can alternatively perform the bandwidth switching and request retransmission of the data portion. Additionally or alternatively, the device can determine a type of the one or more subframes and/or signals transmitted in the one or more subframes to determine whether to perform bandwidth switching in the subframes. The bandwidth switching can include changing a sampling rate, reconfiguring frequency filters, modifying a local oscillator, etc.

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.
