Abstract: Techniques are described for wireless communication. One method includes identifying a set of punctured bit locations in a received codeword. The received codeword is encoded using a polar code. The method also includes identifying a set of information bit locations of the polar code, with the set of information bit locations being determined based at least in part on polarization weights per polarized bit-channel of a polar code decoder that are a function of nulled repetition operations per polarization stage of the polar code identified based at least in part on the set of punctured bit locations. The method further includes processing the received codeword using the polar code decoder to obtain an information bit vector at the set of information bit locations.

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: A method, an apparatus, and a processor-readable storage medium for wireless communication are provided. A transmitter transmits data packets to a receiver, encodes the data packets to generate parity packets, stores the parity packets in a retransmission buffer, receives information from the receiver indicating that a data packet was not correctly decoded, and transmits to the receiver the parity packets stored in the retransmission buffer for recovering the data packet not correctly decoded without retransmitting the data packet not correctly decoded. The transmitter may further retransmit to the receiver the parity packets. The transmitted data packets may be encoded at a medium access control (MAC) layer of the transmitter. The retransmission buffer may be located at a radio link control (RLC) layer or a packet data convergence protocol (PDCP) layer of the transmitter. A reordering buffer at the receiver may be located at the RLC layer or PDCP layer.

Abstract: Techniques are described for wireless communication. One method for wireless communication includes transmitting, to a user equipment (UE), an indication of a control channel subcarrier spacing to be used by the UE; and transmitting a control message having a subcarrier spacing in accordance with the indication. Another method for wireless communication includes transmitting, to a UE, an indicator channel identifying at least a subcarrier spacing to be used in one or more subsequent control channels. One or more subsequent control channels are then transmitted in accordance with the subcarrier spacing indicated by the indicator channel.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for managing the cyclic prefix (CP) type of a transmission as a function of one or more parameters, such as the transmission type (e.g., the type of channel or signal), the resources utilized for the transmission, or the tone spacing of the transmission. In some examples, at least a portion of the downlink and/or uplink control channels or signals utilize a CP having one duration, while other control channels or signals and/or traffic channels may utilize either the same CP or a different CP having a different duration. The CP type or duration for a given transmission may be indicated in various manners.

Abstract: Methods, systems, and devices are described for fountain hybrid automatic repeat request (HARD) for reliable low latency communication. A wireless device may transmit a data block based on a low latency operational mode. The device may then transmit a number of redundancy versions of the data block prior to determining whether an acknowledgement (ACK) has been received. In some examples the ACK may be an augmented ACK, which may be based on the number of redundancy versions received prior to successfully decoding the data block, and which may include an additional resource request. In some examples, the device may select an updated modulation and coding scheme (MCS) based on the augmented ACK. In some examples, the device may increase a number of frequency resources (e.g., component carriers) used for transmission based on the augmented ACK.

Abstract: Various aspects described herein relate to dynamic uplink antenna port management. A user equipment (UE) may receive reference signal configuration information from a base station. The UE may configure one or more uplink antenna ports based on the received reference signal configuration information and transmit one or more reference signals to the base station on the one or more uplink antenna port. The UE may receive uplink configuration information for one or more data channels and/or one or more control channels. The UE may configure one or more uplinks antenna ports based on the uplink configuration information and may transmit one or more uplink signals on the one or more data channels and/or one or more control channels. The uplink configuration information may be based at least one the one or more reference signals transmitted to the base station.

Abstract: Some wireless communications systems may support mobile broadband (MBB) communications and low latency communications. To facilitate low latency communications, a base station may assign resources allocated for an MBB transmission for a low latency transmission. As described herein, to limit interference between an MBB transmission and a low latency transmission while maximizing the chances that the MBB transmission is received, an MBB user equipment (UE) may be configured to adjust a transmit power for the MBB transmission to limit the impact on a low latency transmission without preempting the MBB transmission. However, if the MBB UE is unable to adjust the transmit power for the MBB transmission prior to the MBB transmission, the MBB UE may determine whether to drop a portion of the MBB transmission on the resources assigned for the low latency transmission (e.g., based on whether a received power of the MBB transmission exceeds a threshold).

Abstract: Methods, systems, and devices for wireless communication provide for split symbol control by varying tone spacing and symbol duration for control channels in a subframe. The control symbols may be transmitted at various locations within the subframe and may be transmitted to different mobile devices. In some examples, multiple control symbols may be transmitted in a subframe to multiple mobile devices depending on the capabilities of each of the multiple mobile devices.

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.
