Abstract: Wireless communications systems and methods related to dynamically triggering aperiodic CSI reporting are disclosed. A UE may determine whether a condition is satisfied for triggering upon receipt of a signal from a BS. The condition may be based on a decoding status of the signal. In some examples, the UE may explicitly request a CSI resource signal (e.g., CSI-RS, CSI-IM, or both) from the BS when the condition is met. The explicit request may be included in a modified ACK/NACK field, regardless of whether an ACK or NACK is transmitted. The BS may respond with a CSI resource signal. In other examples, the BS may wait to respond with a CSI resource signal until a threshold number of requests are received from the UE. In other examples, the BS may track a number of NACKs from the UE instead of relying upon an explicit request.

Abstract: Systems, methods, computer-readable medium, and apparatus are disclosed that allow for control information to be provided in an efficient manner during short burst transmission. For example, an apparatus may be configured to receive downlink control information (DCI) that indicates an allocated resource from a base station. The apparatus may also receive data from the base station. The apparatus may generate a cyclically shifted sequence that corresponds to a sequence that is cyclically shifted based on at least one of an ACK or NACK for the received data and a SR. The apparatus may then transmit the cyclically shifted sequence in the allocated resource within one symbol period of a slot of a subframe to the base station. Thus, by transmitting the SR and the ACK/NACK in one symbol, control information for short burst transmissions can be provided in a more temporally efficient manner without adding excessive complexity to the UE.

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. A base station may select, for a user equipment (UE), one or more reuse exception rules to be applied by the UE when reusing one or more resource sets for data communication. The base station may signal the one or more reuse exception rules to the UE. The base station may communicate with the UE in accordance with the one or more reuse exception rules.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that may be configured to receive a downlink control message, to determine a beta offset value for transmitting UCI based at least in part on the downlink control message, and to transmit the UCI on an uplink shared channel interleaved with data based on the determined beta offset value. The apparatus may identify the beta offset from a set of values based on the downlink control message. An apparatus may identify resources allocated for PUSCH and may map UCI to the identified resources for PUSCH in a frequency interleaved manner over a bandwidth of the identified resources. The apparatus may map data to the identified resources in a time-first or frequency-first manner, and may transmit a signal comprising UCI and data on the identified resources of the PUSCH in accordance with the mapping.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select at least one of a primary carrier associated with a physical uplink control channel group or a secondary carrier associated with a physical uplink control channel group for transmitting a physical uplink control channel message to a base station. The UE may transmit, based on selecting at least one of the primary carrier or the secondary carrier, the physical uplink control channel message using at least one of the primary carrier or the secondary carrier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a UE capability associated with reference signal reporting by the UE. The UE may receive, from the base station, a data packet and an indication of a mode for hybrid automatic repeat request (HARQ) feedback reporting based on the UE capability. The UE may determine that a slot includes first resources for transmitting a sounding reference signal (SRS) and second resources for transmitting HARQ feedback for the data packet. The UE may transmit, to the base station during the slot and based on the indication of the mode for HARQ feedback reporting, the HARQ feedback and one or more of the SRS or CSI associated with the HARQ feedback.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a base station or a UE. In an aspect, the apparatus may determine locations for a number of DM-RS symbols to be transmitted in a scheduling unit of a channel configured in a slot/mini-slot, where a last DM-RS symbol maybe positioned one symbol prior to a last symbol carrying scheduled data. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a selection between a first set of predetermined DM-RS positions and a second set of predetermined DM-RS positions. In another aspect, the apparatus may determine the locations for the DM-RS symbols based on a set number of symbols, wherein the determined locations are spaced apart according to the set number of symbols. The apparatus may transmit the DM-RS symbols based on the determined locations.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may identify multiple demodulation reference signal (DMRS) symbols corresponding to multiple DMRS ports of a multiple input multiple output configuration. The transmitting device may generate multiple phase-rotated and precoded DMRS symbols by applying an orthogonal cover code, a phase rotation scheme, and a precoding matrix to the identified DMRS symbols. The transmitting device may map the phase-rotated and precoded DMRS symbols to time-frequency resources corresponding to multiple antenna ports, and transmit a DMRS based on the mapped phase-rotated and precoded DMRS symbols. The transmitting device may transmit the DMRS using multiple antennas that correspond to the antenna ports.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an uplink payload in a wireless communications system. The UE may identify a set of sequences configured for conveying a payload including a set of bits, where each sequence of the set of sequences is orthogonal to each other sequence of the set of sequences. The UE may select a first sequence from the set of sequences based on a mapping between the set of sequences and payload values corresponding to the set of bits. The UE may transmit the payload including the set of bits using the first sequence.
