    Abstract: Some techniques and apparatuses described herein provide generation of a set of orthogonal sequences for transmission of a signal including a payload using an orthogonal base sequence in a time domain. In one example, the orthogonal base sequence in the time domain may be a pi over 2 (pi/2) binary phase shift keying (BPSK) sequence in the time domain, such as prior to transform precoding for transmission. Some techniques and apparatuses described herein provide for the set of orthogonal sequences to be generated such that the set of orthogonal sequences are orthogonal within a symbol (e.g., an orthogonal frequency division multiplexing symbol) by applying an intra-symbol orthogonal cover code (OCC). Applying the intra-symbol OCC provides intra-symbol orthogonality. Thus, a peak to average power ratio of a user equipment is reduced for uplink transmissions and intra-symbol orthogonality is preserved.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a first downlink control information (DCI) message from a base station on a first downlink control channel. The first DCI message may indicate a first set of transmission parameters. The UE may transmit a first uplink control information (UCI) message to the base station on an uplink control channel based on the first DCI message. The first UCI message may include feedback and a channel state information (CSI) report. The UE may receive a second DCI message from the base station on a second downlink channel based on the first UCI message. The second DCI message may indicate a second set of transmission parameters that are different than the first set of transmission parameters. The UE may communicate with the base station using the second set of transmission parameters indicated by the second DCI message.

    Abstract: Methods, systems, and devices for wireless communications are described. A device may include an energy harvesting circuit configured to convert radio frequency energy associated with signals detected by the device to direct current (DC) energy for storage at the device. The device may additionally include a signal decoding circuit configured to decode the signals detected by the device to identify transmissions from other devices in the wireless communications system. The device may rely on power splitting or time switching to direct radio frequency energy to both the energy harvesting circuit and signal decoding circuit of the device. The device may employ various methods for channel estimation, channel reporting, and communications with another device based on utilizing power splitting or time switching to both perform energy harvesting and signal decoding.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support CSI age reporting. In a first aspect, a method of wireless communication includes receiving, by a wireless communication device, a message indicating channel state information (CSI) age reporting; transmitting, by the wireless communication device, a CSI report associated with a first window length and a second window length and indicating at least the second window length, wherein the first window length is associated with computing CSI before an uplink slot of the CSI report, and wherein the second window length is associated with a period of time for which the CSI report is valid. Other aspects and features are also claimed and described.

    Abstract: Techniques described provide dependent procedure operation configured for avoiding or mitigating one or more aspect of the impact on the dependent procedure of cancelling an uplink transmission. One or more attributes (e.g., a transmission indication attribute) associated with a cancelled uplink transmission may be designated for dependent procedure operation, such as for indicating whether the cancelled uplink transmission is considered either as having been transmitted or not having been transmitted. The one or more attributes associated with a cancelled uplink transmission designated for dependent procedure operation may be based upon whether the cancelling the first uplink transmission is a fast cancellation or is a slow cancellation. The designation of a transmission indication attribute for dependent procedure operation may correspond to the dependent procedure and/or its operation. Other aspects and features are also claimed and described.

    Abstract: A base station may configure a new demodulation reference signal (DM-RS) to indicate a skipped semi-persistent scheduled (SPS) physical downlink shared channel (PDSCH) occasion to a user equipment (UE), and the UE may detect a discontinuous transmission (DTX) in the skipped SPS PDSCH occasion based on receiving the new DM-RS within the corresponding PDSCH occasion. The UE may detect that the corresponding PDSCH occasion is a skipped SPS PDSCH occasion by measuring the energy of the PDSCH signal symbols to detect that the PDSCH signal symbols do not include data signal. The UE may measure the DM-RS energy or detect the configuration of the DM-RS to determine that the second PDSCH does not include a PDSCH signal.
