Abstract: Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

Abstract: This disclosure describes systems, methods, and devices related to adaptation of secure sounding signal. A device may determine a negotiated bandwidth to be used when communicating with a first station device. The device may determine a first bit stream used to generate a cyclic shift diversity (CSD) value based on the negotiated bandwidth, wherein a first number of bits is used for the first bit stream when a first negotiated bandwidth is used, and wherein a second number of bits is used for the first bit stream when a second negotiated bandwidth is used. The device may determine a second bit stream used to generate a random phase. The device may determine a secure a long training field (LTF) based on a combination of the first bit stream and the second bit stream. The device may cause to send a frame to the first station device, wherein the frame comprises the secure LTF.

Abstract: This disclosure describes systems, methods, and devices related to dynamic channel bonding and multi-band aggregation. A device may determine a plurality of aggregated medium access control (MAC) protocol data unit (A-MPDU) subframes to send to a station device including a first A-MPDU subframe and a second A-MPDU subframe. The device may determine a quiet period between the first A-MPDU subframe and the second A-MPDU subframe. The device may cause to send the plurality of A-MPDU subframes to the station device on a first channel. The device may determine a status of a second channel during the quiet period. The device may cause to send the second A-MPDU subframe to the station device using a multi-band transmission on the first channel and the second channel.
