Abstract: The disclosure relates in some aspects to scheduling data transmissions based on an end-to-end delay bound. In some aspects, timing information is transmitted in conjunction with data over a given hop, where the timing information is based on an end-to-end delay bound for the data transmission (e.g., according to a latency requirement). For example, the timing information may indicate the time remaining for transmission of a response to the data or the deadline for completing the response. A scheduler that receives the timing information may schedule another transmission (e.g., a response) based on the timing information.

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.

Abstract: Various aspects provide for receiving signaling including information configured to indicate whether to adjust a structure of a time-division duplex (TDD) subframe. Such adjusting may include adjusting a time or subcarrier allocated for a control channel, data, and/or a reference signal, such as a user equipment (UE)-specific reference signal (UERS). The UERS may be time-aligned with a demodulation reference signal (DMRS) of another TDD subframe. The UERS may be utilized for inter-link multi-user multiple-input multiple-output (MU-MIMO) when the UERS is orthogonal to the DMRS. Various other aspects provide for communicating one or more pilot or null tones in a data portion of a first TDD subframe. The one or more pilot or null tones may be used to capture interference from a second TDD subframe communicated by another apparatus. The first TDD subframe may be communicated at least partially concurrent with the second TDD subframe.

Abstract: A method, an apparatus, and a processor-readable storage medium for wireless communication are provided. In an aspect, the apparatus is a subordinate entity that receives an indication of a resource allocated for an uplink transmission. The subordinate entity also receives a condition associated with the resource. The subordinate entity evaluates whether the condition is satisfied and determines whether to transmit a packet using the resource based on the condition being satisfied. In another aspect, the apparatus is a scheduling entity that generates an indication of a resource allocated for an uplink transmission. The resource is associated with a condition that limits access to the resource. The scheduling entity transmits the indication and the condition to a subordinate entity and receives a packet from the subordinate entity via the resource based on the condition being satisfied.

Abstract: Aspects of the disclosure relate to a configurable subframe structure for use in next generation (e.g., fifth generation or 5G) wireless networks utilizing a time division duplex (TDD) carrier that minimizes interference with adjacent legacy wireless networks. The configurable subframe structure may be configured to produce next generation subframes, each including at least one of a downlink portion or an uplink portion, to substantially align downlink portions with corresponding legacy downlink subframes and/or uplink portions with corresponding legacy uplink subframes.

Abstract: Aspects of the present disclosure provide network assistance for distriuted unscheduled transmissions. A scheduling entity may provide unscheduled assistance information to a subordinate entity indicating a respective probability for use in selecting each resource from a subset of available resources for an unscheduled uplink transmissions. The subordinate entity may select at least one resource from the available resources for the unscheduled uplink transmission based on the unscheduled assistance information.

Abstract: Systems and methods for providing mixed interference management are disclosed. Implementations providing mixed interference management may provide operation to receive reported mixed interference information from at least one of one or more user equipments (UEs) served by the base station or from one or more other base stations operable in a same communication system, wherein the mixed interference information comprises information regarding at least one of downlink-to-uplink or uplink-to-downlink interference experienced by a respective reporting one of the one or more UEs and one or more other base stations, and to provide mixed interference management using the reported mixed interference information. The mixed interference information may be used to generate jamming graphs, wherein the jamming graphs provide a mixed interference profile for base stations, and wherein the jamming graphs may be used to determine whether to implement a switch of uplink/downlink subframes based on the interference mitigated mixed interference profile.

Abstract: Methods, systems, and devices are described for determining a quality estimation of a wireless network that may be used to determine whether a particular wireless network meets one or more criteria for association with a station. The quality estimation may be based on a load quality of a basic service set (BSS) of an available wireless network and/or one or more wide area network (WAN) metrics associated with the wireless network. A station may evaluate such load quality and WAN metrics prior to association, and/or after association with a wireless network.

Abstract: Methods, apparatus, and computer-readable media for wireless communication may involve techniques for throughput estimation. An expected air time parameter may be used as a parameter for estimating throughput. The expected air time parameter may be indicative of an estimated air time fraction obtainable for communications using an access point (AP), for example, between a wireless station (STA) and the AP. Either the expected air time parameter or an estimated air time fraction determined (e.g., calculated) from the expected air time parameter may be transmitted from the AP to the STA (or other communication device) to allow the STA (or other communication device) to determine an estimated throughput for communications using the AP.
