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, 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.

Abstract: A method of multiplexing scaled numerology OFDM waveforms in an orthogonal frequency division multiplexing is presented. A first data can be encoded into a first numerology at a first set of tones and a second data can be encoded into a second numerology at second set of tones. A third data can be encoded into a guard band in such a way that the third data can be interpreted under either the first numerology or the second numerology.

Abstract: Coding for bursty interference is discussed in which a base station receives data bits for transmission. The base station may generate code blocks including information bits and parity bits. The base station may also generate parity check code blocks including information bits corresponding to information bits of the generated code blocks. The base station may transmit the code blocks and the parity check code blocks to a mobile device to improve decoding. When errors are detected, the mobile device may decode the received code blocks using hard or soft parity checks and the parity check code blocks.

Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a wireless system may use a staggered uplink/downlink (UL/DL) format in which the symbol periods of the downlink are offset from the symbol periods of the uplink. Thus, if a user equipment (UE) receives a transmission in a first symbol period, it may decode the transmission and transmit a response in a staggered symbol period (e.g., in a UL control channel symbol period beginning one half of a symbol period after the first symbol period). A base station may then receive the response and, if it is a negative acknowledgement (NACK), retransmit during the third symbol period following the first symbol period. In another example, thin control channels may be used to reduce the round trip time between receiving a transmission and a retransmission.

Abstract translation: 描述了用于无线通信的方法，系统和设备。 在一些示例中，无线系统可以使用交错的上行链路/下行链路（UL / DL）格式，其中下行链路的符号周期从上行链路的符号周期偏移。 因此，如果用户设备（UE）在第一符号周期中接收到传输，则它可以对传输进行解码并以交错的符号周期（例如，在UL控制信道符号周期内的符号周期后的一半开始发送响应 第一个符号期）。 然后，基站可以接收响应，并且如果它是否定确认（NACK），则在第一符号周期之后的第三符号周期期间重发。 在另一示例中，可以使用薄控制信道来减少接收传输和重传之间的往返时间。

Abstract: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. Frame formats are disclosed in which control signals are transmitted at different bandwidths than data signals. Receiver architectures for receiving the signaling formats are disclosed. A receiver can receive a relatively narrowband control signal while consuming a relatively low power and then dynamically adjust characteristics of various components to receive a data signal at a higher bandwidth while consuming a relatively higher power.

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.
