Abstract: Various aspects of the disclosure relate to encoding information and decoding information. In some aspects, the disclosure relates to an encoder and a decoder for Polar codes with HARQ. If a first transmission of the encoder fails, information bits associated with a lower quality channel may be retransmitted. At the decoder, the resulting decoded retransmitted bits may be used to decode the first transmission by substituting the retransmitted bits for the original corresponding (low quality channel) bits. In some aspects, to decode the first transmission, soft-combining is applied to the decoded retransmitted bits and the original corresponding (low quality channel) bits. In some aspects, CRC bits for a first transmission may be split between a first subset of bits and a second subset of bits. In this case, the second subset of bits and the associated CRC bits may be used for a second transmission (e.g., a retransmission).

Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive a capability indicator from a user equipment (UE) that indicates a capability of the UE to decode downlink control information (DCI) on a physical downlink shared channel (PDSCH). In some aspects, the base station may transmit, to the UE, the DCI on the PDSCH based at least in part on the capability indicator indicating that the UE can decode the DCI on the PDSCH. Numerous other aspects are provided.

Abstract: Disclosed are techniques for utilizing synchronization signal blocks for positioning operations. In an aspect, a transmission point configures a set of synchronization signal blocks to be used as positioning measurement signals, each of the plurality of synchronization signal blocks comprising a primary synchronization signal, a secondary synchronization signal, and one or more physical broadcast channel signals, and transmits the set of synchronization signal blocks on a wireless downlink channel to enable a user device to perform a positioning measurement of at least one of the set of synchronization signal blocks. In an aspect, the user device receives, from the transmission point, the plurality of synchronization signal blocks on the wireless downlink channel, receives, from the transmission point, an indication of the set of synchronization signal blocks to be used as positioning measurement signals, and performs a positioning measurement of at least one of the set of synchronization signal blocks.

Abstract: The present disclosure relates to methods and devices for communicating based on improved signaling. A base station can transmit an indication of resources in time and frequency to a UE allocated for NOMA communication with the UE. The indication of resources can comprise a set of NA-RUs. The UE can then transmit uplink NOMA communication to the base station based on the indication of resources received from the base station. Also, the base station can transmit a compact UL resource grant via DCI, or signal the semi-static transport format configuration via RRC, to the UEs allocated for NOMA communication. The DCI or the payload of RRC signaling can be scrambled with a NOMA group RNTI, as well as comprise NOMA transmission parameters indicated by a MCS table. The UE can then transmit uplink NOMA communication to the base station based on the DCI or the RRC signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that multiple uplink channels are to be transmitted contemporaneously via different antennas on a component carrier. The user equipment may determine a respective transmit power for multiple uplink communications associated with the multiple uplink channels based at least in part on a set of priority rules that identifies a respective priority for the multiple uplink communications. The user equipment may transmit the multiple uplink communications using the respective transmit power. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.
