Abstract: Shared spectrum operation is disclosed for sharing spectrum among multiple wireless deployments. Coordination procedures between and among 2nd and 3rd Tier deployments include the use of beacons transmitted by the 2nd Tier for clearing access to spectrum occupied by 3rd Tier users and multiple 3rd Tier deployments sharing resources using a group-listen before talk (LBT) protocol, rather than a per-node LBT protocol. The 2nd Tier beacon signals are transmitted to alert 3rd Tier users of their presence, which, upon detection, will leave the particular spectrum within a predetermined time. For the shared LBT protocol, the 3rd Tier deployments share the channel with each other through an LBT with random backoff, in which the start time of clear channel assessment (CCA) procedure and the random backoff values are synchronized among nodes of the same deployment.

Abstract: Control information may be identified and provided to a user equipment (UE) that is formatted into a codeword that is transmitted in a first symbol of a downlink transmission to the UE. The control information may include an allocation of downlink or uplink resources for the UE and data processing parameters. The control information may be partitioned into first control information transmitted in a first codeword and second control information that may be formatted into a second codeword. The second control information may be determined based at least in part on the data acknowledgment from the UE. Such partitioned control information may allow a base station to perform some processing related to transmissions for a transmission time interval (TTI) prior to the start of the TTI, and allow the base station to perform some processing for the TTI after the start of the TTI.

Abstract: Various aspects of the disclosure provide for apparatus, methods, and software for implementing a time division duplex (TDD) wireless communication system that can utilize configurable delays to relax data processing timelines when needed. By implementing these configurable delays, very high data rates may be accommodated at the same time as lower data rates for devices that may have reduced or lesser processing capabilities.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. A base station may select a hybrid pilot configuration including a relatively sparse periodic pilot and a dense pilot embedded in one or more symbols of a low latency burst. A user equipment (UE) may generate a long term statistical average channel estimate based on the periodic pilot and an instantaneous channel estimate (e.g., for demodulation) based on the dense pilot embedded in the low latency burst. The UE may refine the instantaneous channel estimate by converting a control channel embedded with the burst. In some instances, the base station may embed the dense pilots in the first symbol of a burst and transmit subsequent low latency symbols with a reduced density pilot (or without pilot tones).

Abstract: Methods, systems, devices, and apparatuses are described for phase noise estimation. A transmitting device identifies a phase noise metric associated with a receiving device. The phase noise metric provides an indication of the expected phase noise for the receiving device. The transmitting device selects a plurality of pilot tones adjacent to each other and a plurality of null tones for a transmission to the receiving device based on the phase noise metric. The plurality of null tones may be adjacent to and on both sides of the pilot tones in the frequency domain. The transmitting device identifies its own phase noise metric and select the pilot tones adjacent to each other and plurality of null tones in further consideration of its own phase noise metric. The receiving device may use the pilot tones and plurality of adjacent null tones to determine a phase noise estimation for the transmission.

Abstract: Described herein are methods, systems, and apparatus for jointly estimating channel and phase noise in a control symbol. In one example, a method for wireless communication is described that includes inserting a control tone at a first periodicity in a first subcarrier of a control symbol and inserting a pilot tone at a second periodicity in a second subcarrier of the control symbol, the pilot tone being offset from the control tone in the control symbol. The method also includes transmitting the control symbol. In another example, a method for wireless communication is described that includes receiving a control symbol comprising a control tone at a first periodicity, and a pilot tone at a second periodicity, the pilot tone being offset from the control tone in the control symbol. The method also includes performing a phase noise estimation and a channel estimation from the pilot tone.

Abstract: Methods, systems, and devices are described for wireless communication. A first device, such as a user equipment (UE) may be configured with a peak data rate that corresponds to the radio frequency (RF) capacity of a modem and a sustained data rate that corresponds to the baseband capacity. The first device may receive a set of data blocks during a transmission burst from a second device. The quantity of data blocks in the burst may be based on the peak data rate. The first device may store time domain samples or frequency tones for the data and then power down the RF components for an interval based on how long it will take to process the data. The first device may then process the data at the sustained data rate. After the rest interval, the first device may power up the RF components and receive another burst of data.

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 subordinate entity. The subordinate entity receives a transmission from the scheduling entity in a data portion of the subframe. The subordinate entity processes, in the subframe, at least a part of the transmission. The subordinate entity then determines whether to send an acknowledgment (ACK) signal for the transmission, the ACK signal to be transmitted in an ACK portion of the subframe before a remaining part of the transmission is processed, and sends the ACK signal to the scheduling entity in the ACK portion of the subframe based on the determination. The data portion and the ACK portion are contained in the subframe.

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.
