Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Systems, devices, and methods associated with interference aware sounding reference signals are provided. A method for wireless communication includes receiving, at a wireless communication device in communication with a first base station, an interfering signal from a second base station (or others); determining, at the wireless communication device, a spatial direction of the interfering signal; and transmitting, with the wireless communication device, a signal to the first base station based on the spatial direction of the interfering signal. Another method includes receiving, at a first base station, a signal from a wireless communication device, the signal based on a spatial direction of an interfering signal received by the wireless communication device from a second base station (or others); transmitting, with the first base station, a downlink communication to the wireless communication device, the downlink communication beamformed in the spatial direction based on the signal received from the wireless communication device.

Abstract: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. A mobile device receives a control signal having a first bandwidth. The mobile device receives a data signal having a second bandwidth different from the first bandwidth. The control signal and the data signal are received over a single carrier frequency. The data signal is transmitted after the control signal such that the data signal and control signal are separated by a time interval. The time interval is based on a switching latency of the mobile device.

Abstract: Aspects of the present disclosure provide a configurable bi-directional time division duplex (TDD) subframe structure. The configurable subframe structure includes a downlink control portion, an uplink control portion, an uplink data portion and a downlink data portion. A current subframe for communication between a scheduling entity and a set of one or more subordinate entities is produced by determining a desired ratio of uplink information to downlink information for the current subframe and configuring the configurable subframe structure with the desired ratio.

Abstract: Techniques are described for signaling a downlink bandwidth part (BWP) switching event and an aperiodic channel state information (A-CSI) request in a paired spectrum environment. The base station may transmit uplink scheduling downlink control information (DCI) to a user equipment (UE) that includes the A-CSI request and an identifier for the downlink BWP of the downlink BWP switching event. After receiving the A-CSI request and the downlink BWP, the UE may perform one or more CSI measurements using the downlink BWP. The UE may use physical uplink shared channel (PUSCH) resources associated with the uplink scheduling DCI to transmit the CSI report to the base station. Using these techniques, the base station may be configured to indicate that a downlink BWP switching event is to occur and allocate PUSCH resources to the UE to be used to transmit the CSI report associated with the downlink BWP switching event.

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract: Wireless communications systems and methods related to the reduction in a probability of collision for grant-less transmissions from internet of everything (IOE) devices while not increasing search complexity at a base station are disclosed. An IOE device randomly selects a first access resource from a common pool that the base station searches to initiate a transmission. If a metric associated with the data transmission is predicted to exceed a threshold, the IOE device also requests a second access resource from a reserved access pool from the base station, that the base station does not search. The IOE includes the request in the data transmission. The base station and the IOE device switch to the second access resource after the base station identifies an available resource from the reserved access pool and the IOE device completes the data transmission using the second access resource.

Abstract: One or more selectively activated features needed at a device to use a network service may be identified. Authorization information and feature activation key(s) associated with features that the device has been authorized to activate may be obtained at the device. The feature activation key(s) may be used to activate and/or maintain activation of the authorized features that match the selectively activated feature(s) needed to use the network service. An authorization server may obtain a request to activate one or more selectively activated features of a device. The authorization server may verify that the selectively activated feature(s) are authorized to be used at the device based on an authorization agreement obtained at the authorization server. The authorization server may send proof that the device is authorized to use the selectively activated feature(s) and may send feature activation key(s) based on the authorization agreement in response to the request.

Abstract: Systems and methods are disclosed for minimizing latency between receipt of a NACK at a base station from a user equipment (UE) and retransmission of data to the UE. Time constraints for processing the ACK/NACK are relaxed so the base station can decode the ACK/NACK to determine whether a NACK has been received and then prepare for transmission of the appropriate data to the UE in the immediately following transmission time interval (TTI). These constraints are relaxed by separating download data indicator (DDI) from the PDCCH control data and delaying transmission of the DDI until decoding of the ACK/NACK.
