Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify a set of power configurations for a plurality of communications with at least one target device. The set of power configurations may be based at least in part on a type of signal, a type of channel, a parameter of the wireless device, a parameter of the target device, or a combination thereof. The wireless device may then determine a duplexing mode for the plurality of communications based at least in part on the set of power configurations. The duplexing mode may be, for example, a full duplex mode or a half-duplex mode. The wireless device may then transmit the plurality of communications to and/or receive the plurality of communications from the at least one target device according to the set of power configurations and the selected duplexing mode.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, radio signals may reach a receiving antenna at a user equipment by two or more paths, which can cause interference (e.g., destructive multipath interference, constructive multipath interference, etc.). To reduce the interference, the user equipment may perform interference suppression, shaping, or both based on choosing radar waveform patterns that are varied across chirps. In one aspect, the user equipment (e.g., a vehicle) may identify waveform patterns selected by nearby vehicles based on side channel or centralized signaling and may suppress or shape interference by selecting waveform parameters based on this information. In one aspect, the pattern of waveform parameters is chosen from a codebook of patterns. The selected pattern can be broadcasted to the other vehicles using a side-communication channel.

Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.

Abstract: A method and apparatus for selecting frequency modulated continuous wave waveform parameters for multiple radar coexistence by a user equipment is described. The user equipment may transmit a radar waveform consisting of a number of chirps, with each chirp having a same duration. The user equipment may vary waveform parameters of the radar waveform for at least a subset of the number of chirp, where the waveform parameters may be chosen from a codebook comprising at least one codeword of parameters. Reflected radar waveforms are received and processed where the processing includes applying a fast time discrete Fourier transform to reflected radar waveforms to produce a one dimension peak in a time delay dimension for each reflected waveform; and applying a slow time discrete Fourier transform to the reflected radar waveforms, where peaks for the reflected waveforms are added.

Abstract: Methods, systems, and devices for wireless communications are described that provide for signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). A threshold value may be determined, which corresponds to an amount of time for a UE to receive and decode control information, and apply a different BPL than a current BPL that that is in use. The UE may maintain a BPL for data, which is used during data transmission time intervals (TTIs) until an indication is received to change the BPL for data. The UE and the base station may determine to change between BPLs based at least in part on the threshold value and a scheduling offset between a control channel transmission that allocates resources for a data TTI and a start of the data TTI.

Abstract: Methods and apparatuses for wireless communication are provided. A transmitting apparatus receives an indication to use multiple subframes to send uplink control information, codes the uplink control information over the multiple subframes based on the indication, and sends the coded uplink control information via the multiple subframes. Sending the coded uplink control information includes transmitting acknowledgement information (ACK) of a current downlink-centric self-contained subframe in an uplink acknowledgement portion of the current downlink-centric self-contained subframe, bundling ACK bits of multiple downlink-centric self-contained subframes and encoding the bundled ACK bits to generate parity acknowledgement bits associated with systematic acknowledgement bits, transmitting the systematic acknowledgement bits in each uplink acknowledgement portion of the multiple downlink-centric self-contained subframes, and transmitting the parity acknowledgement bits associated with the acknowledgement information bits of the multiple downlink-centric self-contained subframes in an uplink-centric self-contained subframe that is sequentially subsequent to the multiple downlink-centric self-contained subframes.
