Abstract: Techniques are described for wireless communication. A first method includes measuring, by a first device, a condition of a wireless channel; and generating at least one channel side information feedback message based on the measured condition of the wireless channel. The at least one channel side information feedback message provides information on a relationship of a set of parameters, including a data rate parameter, an error probability parameter, and at least one of a deadline parameter or a transmission link parameter. A second method includes measuring, by a first device, interference on a wireless channel; identifying an interfering device for the wireless channel based on the measurement; and generating a channel side information feedback message based on the measured interference on the wireless channel. The channel side information feedback message indicates the interfering device for the wireless channel and a correlation of interference from the interfering device with time or frequency.

Abstract: Aspects of the present disclosure provide an apparatus and techniques for managing interference across operators. A base station identifies a first region of a first frequency spectrum assigned to a first operator, wherein uplink and downlink subframe configurations for Time Division Duplex (TDD) communications using the first region and a first region of a second frequency spectrum assigned to a second operator are synchronized between the first and second operator. The base station further identifies a second region of the first frequency spectrum, wherein uplink and downlink subframe configurations for TDD communications using the second region and a second region of the second frequency spectrum are not synchronized between the first and second operator. The base station communicates with one or more user equipments using the first and second region of the first frequency spectrum.

Abstract: Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes identifying a transmission timing of a control reference signal transmitted over a radio frequency spectrum band during an OFF duration of the UE with respect to the radio frequency spectrum band, in which the identified transmission timing is relative to a transition from the OFF duration to an ON duration of the UE with respect to the radio frequency spectrum band; receiving the control reference signal at the identified transmission timing; and performing a warm-up procedure, before the ON duration, based at least in part on the identified transmission timing of the control reference signal. A method for wireless communication at a wireless network includes indicating, to the UE, the transmission timing of the control reference signal; and transmitting the control reference signal at the indicated transmission timing. The OFF duration and the ON duration are coordinated with a wireless network.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The method may be performed by a scheduling entity. The scheduling entity transmits control information in a control portion of the subframe, the control information corresponding to data information within the subframe, transmits the data information in a data portion of the subframe, receives a pilot signal from the set of subordinate entities in a pilot portion of the subframe, and receives an ACK/NACK signal from the set of subordinate entities in an ACK portion of the subframe. The ACK portion is subsequent to the pilot portion of the subframe. The ACK/NACK signal includes acknowledgment information corresponding to the data information. The control portion, the data portion, the pilot portion, and the ACK portion are contained in the same subframe.

Abstract: Aspects of the present disclosure provide a scheduling entity in communication with a set of scheduled entities within a wireless communication network. The scheduling entity groups a plurality of tones into uplink clusters, where each uplink cluster includes one or more adjacent tones. In addition, the scheduling entity maps a first set of uplink clusters to a first virtual cluster group (VCG) for an uplink control channel, assigns the first VCG to a first scheduled entity of the set of one or more scheduled entities, provides a first VCG index identifying the first VCG to the first scheduled entity and receives uplink control information from the first scheduled entity on the first VCG over the uplink control channel.

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: Aspects of the present disclosure provide various wireless communication numerology designs that can maintain symbol boundary alignment while multiplexing different numerologies in wireless communication. The symbols may be scaled for different tone or subcarrier spacings while maintaining the symbol boundary alignment between different numerologies. Maintaining the symbol-boundary alignment between different numerologies enables symbol-level numerology multiplexing. The disclosed numerology designs enable low latency communication and improved interference management, and provide non-ambiguous symbol boundary timing reference for multiplexing different numerologies.

Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for enabling a single media access control (MAC) layer to control a variety of physical (PHY) layers or entities for multiplexing signals corresponding to each of the PHY layers over an air interface. Here, the MAC layer may include a resource manager configured to determine a time-frequency resource allocation within the air interface for communication with one or more subordinate entities utilizing each of the PHY layers. In this way, The MAC entity may provide dynamic control over the allocation of time-frequency resources within a given resource group, which may include transmission time intervals (TTIs) having multiple time scales.
