Abstract: Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

Abstract: Adaptive pilot signaling is disclosed in which resources allocated to pilot symbols are allowed to vary to more closely match channel conditions. User equipments (UEs) may request different pilot configurations depending on channel conditions. In one embodiment, a method includes receiving a first set of pilot symbols using a first number of resource elements during a first transmission time interval (TTI), and receiving a second set of pilot symbols using a second number of resource elements during a second TTI. In the embodiment, the first TTI and the second TTI include the same number of resource elements, and the first number of resource elements is different than the second number of resource elements.

Abstract: Methods, apparatus, and systems for wireless communication are provided. A method for wireless communication includes configuring a first device for a first mode of communication, receiving wide area network (WAN) scheduling information from downlink signals received from a network entity when a radio air interface of the first device is configured for the first mode of communication, configuring the first device for a second mode of communication, determining a mesh network schedule based on the WAN scheduling information, and communicating wirelessly with a second device in accordance with the mesh network schedule when the radio air interface is configured for the second mode of communication. The first device and the second device may communicate at power levels below a power level threshold selected to cause the network entity to ignore transmissions between the first device and the second device.

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 other base stations); 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 of wireless communication 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 other base stations); 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: Aspects of the present disclosure provide a self-contained subframe structure for time division duplex (TDD) carriers. Information transmitted on a TDD carrier may be grouped into subframes, and each subframe can provide communications in both directions (e.g., uplink and downlink) to enable such communications without needing further information in another subframe. In one aspect of the disclosure, a single subframe may include scheduling information, data transmission corresponding to the scheduling information, and acknowledgment packets corresponding to the data transmission. Furthermore, the subframe may additionally include a header and/or a trailer to provide certain bi-directional communications functions.

Abstract: Systems, methods, apparatuses, and computer-readable storage media for managing power consumption of a mobile device are disclosed. The systems, method, apparatus, and computer-readable storage medium may cause the base station to identify an energy metric associated with a mobile device, and to configure the transmission between the base station and the mobile device based at least in part on the energy metric. The configuration of the transmission may reduce the power consumption of the mobile device for processing the transmission.

Abstract: Systems and method of embodiments herein operate to conserve battery power of user equipment (UE). Embodiments determine whether waking up a UE receiver would be beneficial and based on the determination, the UE either wakes up the receiver or returns to sleep. Embodiments determine whether to wake up the receiver by performing pre-wake up (PWU) operation which either wakes up the receiver in a low power mode or wakes up the UE's wake up receiver. It may be determined whether a wake up (WU) signal is received during a PWU stage. If a WU signal is received during the PWU stage the UE may perform a full wake up of the receiver. If a WU signal is not received the UE may return to idle mode. In embodiments, WU (Wake Up) DRX cycles are supplemented with a Full DRX (Discontinuous Reception) cycle.

Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

Abstract: Aspects of the disclosure provide a slot structure (e.g., the arrangement of channels and pilot signals within a slot) that can relax the processing timeline for a wireless communication device. For example, in the first or initial symbol of a slot, control information may be frequency division multiplexed (FDM) with a demodulation reference signal (DMRS) or with user data. In some cases, delayed-processing data may be sampled, and the samples may be buffered at the receiving device, for processing later, after control information needed to process the data has been received and processed. Further aspects provide for payload pre-tapering. That is, when a device delays the processing of data bits, this can cause a processing bottleneck after that buffering delay. By virtue of various pre-tapering techniques described herein, the processing load needed to process the delayed-processing data can be reduced. Other aspects, embodiments, and features are also claimed and described.
