Abstract: This disclosure provides systems, methods, and devices for wireless communication that provide a mechanism for managing a sequential order for performing a deferral procedure and at least one other slot index-dependent procedure in a wireless communication system. In particular aspects, a user equipment, UE, may be configured to perform a first slot index-dependent procedure and a deferral procedure of uplink repetitions. The UE may determine a sequential order for performing the deferral procedure and the first slot index-dependent procedure, and may then perform the deferral procedure and the first slot index-dependent procedure in the sequential order. The sequential order may include performing the deferral procedure before the first slot index-dependent procedure, performing the deferral procedure after the first slot index-dependent procedure, or a sequential order that is based on a type of procedure of the first slot index-dependent procedure.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify an angle parameter for encoding uplink messages using a fractional Fourier Transform (FrFFT). A base station may transmit a set of angle parameters or a single angle parameter that the UE is to use for encoding an uplink message. The UE may select an alpha value from the set of alpha values for the encoding. The UE may transmit an indication of a set of proposed angle parameters to the base station, and the base station may determine and indicate one of or a subset of the received set of proposed angle parameters to the UE. The base station may indicate a correspondence between angle parameters and beam configurations, and the UE may identify an alpha parameter value based on a subsequently indicated beam configuration.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for maintaining phase coherency in the event of changes to uplink transmit power. For example, the techniques described herein may help mitigate the impact on phase continuity of uplink transmissions by UEs capable of dual connectivity (DC).

Abstract: Methods, systems, and devices for wireless communication are described for a data channel-referenced resource allocation for a control channel. In an implementation, a user equipment (UE) may identify, for a transmission time interval (TTI), a first uplink resource allocation to the UE of a first channel. The UE may determine, based at least in part on the first uplink resource allocation of the first channel, a second uplink resource allocation of a second channel to the UE. The UE may transmit, during the TTI, the first channel and the second channel.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may provide a feedback message to a base station that includes a feedback report that indicates successful or unsuccessful receipt of multiple downlink transmissions, and also includes an indication of a number of unsuccessful receipts that are due to unsuccessful receipt of data channel communications. The indication of the number of unsuccessful receipts of data channel transmissions may be provided as a binary representation of the total number, or may be provided as a quantized value in which each quantized point is associated with a certain number of unsuccessfully received data channel transmissions.

Abstract: Certain aspects of the present disclosure provide techniques for uplink control information (UCI) transmission for overlapping physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resource assignments with repetition. A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving scheduling to transmit on the PUSCH in a first one or more slots associated with a first number of repetitions and scheduling to transmit on the PUCCH in a second one or more slots associated with a second number of repetitions. The scheduled transmissions overlap in at least one slot. The method includes determining which channel to transmit UCI on and which channel to drop for each of the first and second one or more slots. The method includes transmitting or dropping the UCI in the first and second one or more slots in accordance with the determination.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may separately encode lower priority uplink control information (UCI) and higher priority UCI, and multiplex the encoded lower priority UCI and the encoded higher priority UCI on the same physical uplink channel (e.g., a physical uplink control channel (PUCCH)). The UE may be configured with multiple coding rates, which the UE may select from based on a payload size associated with each of the lower priority UCI and the higher priority UCI. Alternatively, the UE may be configured with a separate set of coding rates for the lower priority UCI and a separate set of coding rates for the higher priority UCI. The UE may multiplex the lower priority UCI and the higher priority UCI by mapping to physical uplink channel resources based on an order (e.g., mapping higher priority UCI followed by mapping lower priority UCI).

Abstract: A method of wireless communication at a transmitting device includes adding parity check bits to a set of information bits. The method also includes generating a non-coherent transmission signal by mapping the parity check bits and the set of information bits into a sequence of complex symbols. Further, the method may include transmitting the non-coherent transmission signal to a receiving device. A method of wireless communication at a receiving device includes receiving, from a transmitting device, a non-coherent signal having at least one segment. Each segment comprises a sequence of complex symbols corresponding to information bits and parity check bits. The method also includes jointly detecting the sequences from each segment of the received non-coherent signal by using the parity check bits.
