Abstract: Wireless communications systems and methods related to transmitting sidelink channel state information (CSI) from one user equipment (UE) to another UE using a L1 signal. A first UE requests a CSI report from a second UE. The first UE sends a reference signal which the second UE measures to determine channel characteristics. The second UE forms a CSI report which includes a rank indicator, a channel quality indicator, and potentially a precoding matrix index indicator. The second UE forms the CSI report at the PHY level. The CSI report is included in reserved field(s) of a second stage sidelink control information (SCI-2). The first UE receives and processes the CSI report at a PHY level.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives a first control message indicating a codeblock group (CBG) scheduling configuration for scheduling CBG-based uplink communications, where the CBG scheduling configuration includes a first mapping configuration associated with uplink communications including a single codeword and a second mapping configuration associated with uplink communications including multiple codewords. The UE receives a second control message scheduling an uplink message including a set of CBGs, where the uplink message is associated with a first codeword, a second codeword, or both. The UE then transmits the uplink message in accordance with the CBG scheduling configuration, where the set of CBGs are mapped to one of the first or second codeword in accordance with the first mapping configuration, or where the set of CBGs are mapped to the first and second codewords in accordance with the second mapping configuration.

Abstract: A UE may multiplex first UCI of a first priority with second UCI of a second priority. The first UCI may include at least one of a first modulation order or a first number of MIMO layers, and the second UCI may include at least one of a second modulation order or a second number of MIMO layers. The first modulation order of the first UCI may be greater than or equal to the second modulation order of the second UCI, and the first number of MIMO layers of the first UCI may be greater than or equal to the second number of MIMO layers of the second UCI. The UE may transmit, to a base station, an UL transmission including the first UCI of the first priority multiplexed with the second UCI of the second priority, where the second priority corresponds to a higher priority than the first priority.

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: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

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: Wireless communication devices, systems, and methods related to mechanisms to implement improved interference tracking over time. A BS may transmit information to a UE that allows the UE to quantize channel measurements into interference states. The UE may transmit an interference change report as triggered by an event, such as an interference metric exceeding a threshold after quantizing into the interference states. This enables the system to capture and respond to abrupt changes. Further, the interference change report may include historic interference information. The UE may include statistics based on the historic interference information. The UE may further be triggered to transmit an interference change report in response to a BS requesting it, or in response to a configured period of time elapsing. The UE may further include MCS information predicted for one or more future time periods based on historic information, which the BS may use in scheduling.
