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.

Abstract: Methods, systems, and devices for wireless communications are described in which multiple access (MA) signatures may be used in non-orthogonal multiple access (NOMA) transmissions to provide differentiation between multiple concurrent NOMA transmission that use common time, frequency, and spatial resources. Systematic extension of the pool size of MA signatures can be obtained by the grouping of UE-specific spreading codes and the application of group-specific scrambling code, where the generation of scrambling code can depend at least on a cell ID and UE group ID. The MA signature may be based at least in part on a UE specific spreading code and a group level scrambling code. The UE-specific spreading code may be one of a set of codes associated with a particular scrambling code. The scrambling code may be one of a number of orthogonal or non-orthogonal scrambling codes that are associated with one or more UE parameters.

Abstract: A wireless network may provide system information by either a fixed periodic broadcast or broad-beam transmission or in response to a request by a user equipment (UE). The wireless network may broadcast (or broad-beam transmit) a signal that indicates to the UEs within a cell or zone coverage area that system information is to be transmitted on a fixed periodic schedule or in response to a request sent by one or more UEs.

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: Techniques are described for wireless communication. A first method includes transmitting a first signal to indicate accessing a first channel in a radio frequency spectrum band, and transmitting information with the first signal in the radio frequency spectrum band. A second method includes winning contention to access a radio frequency spectrum band, and after the winning contention to access the radio frequency spectrum band, transmitting a first signal to align a starting point of a second signal with a reference boundary associated with the radio frequency spectrum band. A third method includes winning contention to access a radio frequency spectrum band during a first frame period, the first frame selected from a plurality of different frame periods, and transmitting a signal at a periodicity during one or more subframes of the first frame period for each of the plurality of different frame periods.

Abstract: Methods, systems, and devices are described for low latency communications within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system and may send triggers to initiate communications using a dedicated resource in a wireless communications network that supports transmissions having a first subframe type and a second subframe type, the first subframe type comprising symbols of a first duration and the second subframe type comprising symbols of a second duration that is shorter than the first duration. Communications may be initiated by transmitting a trigger from the UE or eNB using the dedicated resource, and initiating communications following the trigger. The duration of time between the trigger and initiating communications can be significantly shorter than the time to initiate communications using legacy LTE communications.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive configuration information that signals a first set of resources and a second set of resources. The configuration information may indicate that the first set of resources is associated with high priority transmissions and the second set of resources is associated with low priority transmissions. The UE may select, based at least in part on the configuration information and a priority of a transmission, either the first set of resources or the second set of resources for transmitting the transmission. The selecting of the first set of resources or the second set of resources may be based on latency requirements or reliability requirements of transmissions to be transmitted by the UE. The UE may transmit the transmission using the selected set of resources. Other aspects are provided.

Abstract: Techniques for determining resources to use for peer-to-peer (P2P) communication are disclosed. In an aspect, a network entity may receive feedback information (e.g., resource usage information and/or channel state information) from P2P devices and may perform resource partitioning based on the feedback information to allocate some of the available resources for P2P communication. The allocated resources may observe little or no interference from devices engaged in wide area network (WAN) communication. In another aspect, P2P groups may perform resource negotiation via a WAN connection (e.g., with little or no involvement by the WAN) to assign the allocated resources to different P2P groups. In yet another aspect, a device may autonomously determine whether to communicate with another device directly or via a WAN, e.g., whether to initiate P2P communication with another device and whether to terminate P2P communication. In yet another aspect, a network entity may participate in resource negotiation by P2P devices.

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: Methods, systems, and devices for wireless communications are described that provide for concurrent reference signal transmissions using common resources, such as demodulation reference signal (DMRS) transmissions, from a number of non-orthogonal multiple access (NOMA) transmitters. Different transmitters may use different sequences for reference signal transmissions, which may allow a receiver, such as a wireless base station, to decode the reference signal transmissions for each NOMA transmitter and perform channel estimation for each NOMA transmitter. The reference signal transmissions may be asynchronous with a bounded timing offset or quasi-synchronous, and the reference signal sequence selection may provide for relatively reliable channel estimation and coherent demodulation.
