Abstract: A transmitter may initiate multiple-input multiple-output (MIMO) communications with a receiver in which a number of codewords used in MIMO transmissions may be selected to provide enhanced communications for a particular service that is associated with the MIMO transmission. In cases where a lower-latency service is identified, a MIMO transmission may be configured with one codeword transmitted over multiple spatial layers, which may provide lower processing latency at a receiver relative to processing of multiple codewords. In cases where a mobile broadband service is identified, a MIMO transmission configured with two (or more) codewords may be transmitted over multiple spatial layers, which may provide increased data throughput relative to a single codeword MIMO transmission. A codeblock size for a transmission also may be selected based at least in part on a service associated with the transmission.

Abstract: Aspects of the present disclosure provide a self-contained subframe structure for time division duplex (TDD) carriers. Information transmitted on a TDD carrier may be grouped into subframes, and each subframe can provide communications in both directions (e.g., uplink and downlink) to enable such communications without needing further information in another subframe. In one aspect of the disclosure, a single subframe may include scheduling information, data transmission corresponding to the scheduling information, and acknowledgment packets corresponding to the data transmission. Furthermore, the subframe may additionally include a header and/or a trailer to provide certain bi-directional communications functions.

Abstract: Aspects of the disclosure relate to a coexistence of a first radio access technology (RAT), such as a fifth generation (5G) new radio (NR) technology with a second RAT, such as a narrow-band internet-of-things (NB-IOT) technology. In a first aspect, a 5G NR resource block size and an NB-IOT resource block size are defined, and a compatible alignment of an NB-IOT resource block and a 5G NR resource block is identified. An offset associated with the compatible alignment is then determined in which the offset is within a threshold offset and facilitates an identification of a valid NB-IOT resource block. In a second aspect, an offset associated with a compatible alignment of a 5G NR resource block and an NB-IOT resource block is ascertained, and a channel raster is shifted according to the offset associated with the compatible alignment.

Abstract: Methods, systems, and devices for wireless communication are described. One method includes identifying a plurality of intermediate precoders corresponding to a plurality of tone subsets. The plurality of intermediate precoders define a plurality of vectors across the plurality of tone subsets. The method further includes selecting, for each vector of the plurality of vectors, a subset of non-frequency domain components of the vector, such as time-domain components; modifying the plurality of intermediate precoders to a plurality of smoothed precoders based at least in part on the selected subset of non-frequency domain components for each vector; and precoding a plurality of transmit streams using the plurality of smoothed precoders. The plurality of smoothed precoders is smoothed in a frequency domain compared to the plurality of intermediate precoders. Smoothing precoders may enable application of wideband channel estimation techniques using user equipment (UE)-specific reference signals.

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: Techniques for transmission of Ultra-Reliable Low-Latency Communications (URLLC) data over Time Division Duplex (TDD) using a URLLC configuration for a TDD subframe are disclosed. The techniques include determining that data scheduled for transmission using a TDD band over a TDD subframe includes Ultra-Reliable Low-Latency Communications (URLLC) data, and in response, utilizing a URLLC subframe configuration for the TDD subframe. The URLLC subframe configuration includes downlink intervals and uplink intervals.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitter, such as a user equipment and/or a base station, may perform polar coding to encode bits. The polar coding may be associated with a plurality of component channels associated with a polar code length. The transmitter may interleave the encoded bits. The transmitter may map the interleaved encoded bits to a modulation symbol. The interleaving and mapping of each encoded bit may be based on an asymmetry of a polar code construction. The transmitter may transmit the interleaved encoded bits based on the mapping.

Abstract: A combined symbol constellation may be selected from a uniform symbol constellation that is supported by a de-mapper to provide additional power split options while reducing modifications to the de-mapper. In some examples, a signal may be constructed according to a combined symbol constellation selected from a larger uniform symbol constellation based on a desired power-ratio. The signal may include a base-layer, used to communicate a first set of data, and an enhancement-layer, used to communicate a second set of data, in accordance with the selected combined symbol constellation. The signal may be received and de-mapped according to the combined symbol constellation at a de-mapper that supports a uniform symbol constellation that is larger than the combined symbol constellation.

Abstract: The disclosure relates in some aspects to multiplexing different types of traffic. Techniques are disclosed to facilitate puncturing one type of traffic with another type of traffic (e.g., traffic having more stringent latency and/or reliability requirements). In some aspects, these techniques mitigate potential loss of control information for the punctured traffic. In some aspects, the disclosed techniques are applicable to mobile broadband traffic and mission critical traffic.
