Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may identify a reference signal sequence (e.g., a demodulation reference signal (DMRS) sequence) based on a cyclic shift associated with a control channel for communications with a second wireless device. For example, the first wireless device may identify the cyclic shift associated with transmitting a message to the second wireless device via the control channel. In another example, the first wireless device may estimate the cyclic shift associated with receiving a message from the second wireless device via the control channel. The first wireless device may then communicate with the second wireless device based on the reference signal sequence. For example, the first wireless device may transmit or receive (e.g., via a shared channel) the reference signal sequence to or from the second wireless device.

Abstract: Methods related to wireless communication systems and the transmission of code blocks on such systems are provided. A wireless communication device interleaves a plurality of code block segments in time and frequency. The segments are interleaved by mapping a first code block segment of the plurality of code block segments to a first resource located at a first time and a first frequency, wherein the first code block segment is associated with a first code block, and mapping a second code block segment of the plurality of code block segments to a second resource based on at least one of the first time or the first frequency of the first resource and a code block proximity parameter, wherein the second code block segment is associated with a second code block different from the first code block. The device then transmits the plurality of interleaved code block segments. Other features are also claimed and described.

Abstract: A device generates an estimated size of encoded versions of one or more pictures of video data prior to generating the encoded versions of the one or more pictures. A physical layer of a radio system of the device is configured to send a message to a wireless base station. The message indicates a size value based on the estimated size of the encoded versions of the one or more pictures. The physical layer of the radio system receives an uplink grant notification in response to the message. Based on the uplink grant notification, the physical layer of the radio system sends packets to the wireless base station containing the encoded versions of the one or more pictures.

Abstract: Methods, systems, and devices for wireless communications are described. Beam management procedures may increase communications quality and reliability in wireless networks that support narrow directional beams and high frequencies. Some such beam management procedures utilize continuous beam measurements and adaptive beam switching to maintain a threshold link level between devices. A user equipment (UE) may transmit an indication of a capability to perform a first beam refinement procedure in response to a data transmission and using multiple receive beams. The UE may select a communication beam using a first instance of a second beam refinement procedure, and may receive a data transmission from a base station using the selected beam. Based on receiving the data transmission, the UE may perform the first beam refinement procedure and may skip a second instance of the second beam refinement procedure.

Abstract: Method and apparatus are provided for power saving by detecting empty symbols. In accordance with some implementation, a UE may determine that a data channel is not allocated to it by determining that there is no beam directed to it and there was no prior resource allocation to it. The UE upon such determination may enter sleep mode until the start of the next scheduling unit. This may result in reduction in power consumption compared to entering sleep mode after demodulating and decoding the control channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may synchronize a beam switch of the base station with transmission of a reference signal for channel state feedback, and schedule a channel state feedback report to be transmitted after the transmission of the reference signal for channel state feedback. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A non-coherent modulation configuration may be selected for a transmission of a set of data based on a radio frequency spectrum band used for the transmission. After selecting the non-coherent modulation configuration, the set of data may be modulated using a differential phase shift keying modulation technique. After selecting the non-coherent modulation configuration, a set of frequency-domain symbols may be generated from the set of modulated symbols using a discrete Fourier transform. The set of frequency-domain symbols may be mapped to a set of subcarriers, and a time-domain waveform may be generated from the mapped set of frequency-domain symbols, yielding a time-domain waveform. The time-domain waveform may be transmitted over the radio frequency band.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, to improve throughput via more intentional tone reservation, a receiving device (e.g., a user equipment (UE)), may identify one or more tones that have poor signal quality. The receiving device may transmit an indication of the one or more tones having poor signal quality to a transmitting device. The transmitting device may reserve one or more of the identified tones for use in a tone reservation scheme, such as to carry peak-to-average power ratio (PAPR) reduction signals, and may transmit data signals over tones that have higher signal quality.

Abstract: Methods, systems, and devices for wireless communications are described. A link quality characteristic may be determined for a channel having a set of channel characteristics. The determined link quality characteristic may be used to estimate the equivalent link quality characteristic for different demodulation reference signal configurations given the side information of the set of channel characteristics. A mapping defined per set of channel characteristics may be used to determine the estimated equivalent link quality characteristics from the determined link quality characteristic. A demodulation reference signal configuration may be selected based on the estimated equivalent link quality characteristics and a communication efficiency metric. The demodulation reference signal configuration that maximizes the communication efficiency metric may be selected. The selected demodulation reference signal may be signaled to a device that transmits demodulation reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device such as a base station and a user equipment (UE), may segment a set of bits within a transport block into a first subset of bits including modulation bits and a second subset of bits including index modulation bits. The transmitting device may map the first subset of bits to a first set of subcarriers, the second subset of bits to a second set of subcarriers, and an additional set of bits to a third set of subcarriers. The transmitting device may generate a signal according to a boosting factor based on mapping the first subset of bits, the second subset of bits, and the additional set of bits, and transmit the generated signal to a receiving device.
