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.

Abstract: Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

Abstract: Methods, systems, and devices for multiple random access channel (RACH) message 1 (Msg1) transmission for physical downlink control channel (PDCCH) ordered RACH are described. A user equipment (UE) may perform the multiple Msg1 transmission as part of a CFRA or CBRA procedure for access. The UE may perform the multiple Msg1 transmissions in a cyclic consecutive manner during configured RACH occasions or according to explicit time and frequency indications of a random access response (RAR) window. Based on the multiple Msg1 transmission procedure, the UE may reduce latency for random access procedure on the RACH and improve signaling throughput. In some cases, the UE may support beam correspondence and may perform multiple Msg1 transmissions to enhance multi-beam diversity during RACH transmission by performing transmission corresponding to RACH occasions mapped to different synchronization signal blocks (SSBs).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first message indicating a plurality of measurement configurations, each measurement configuration of the plurality of measurement configurations may include different sets of measurement parameters used for measuring a reference signal (RS) of a cell. The UE may also receive, from the base station, a second message indicating that the UE activate a first measurement configuration, deactivate the first measurement configuration, or switch to the first measurement configuration, where the first measurement configuration is from the plurality of measurement configurations. The UE may determine a measurement reporting scheme based at least in part on the indication to activate, deactivate, or switch to the first measurement configuration.

Abstract: Aspects of the present disclosure provide for opportunistic uplink transmissions within a slot. In some examples, after scheduling all regular uplink transmissions within a current slot, a base station (e.g., gNB) may identify a set of unused uplink resources within the current slot and generate and transmit unused resource information identifying the set of unused resources to the user equipment (UE) within the cell served by the base station. If a particular UE is configured to operate in an opportunistic mode, the UE may utilize the unused resource information to generate and transmit an opportunistic uplink transmission within the set of unused uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described herein for managing timers for hybrid automatic repeat request (HARQ) processes associated with multiple configured grants that are active at the same time. Techniques are also described herein for allocating HARQ identifiers (IDs) to HARQ processes associated with multiple configured grants that are active at the same time. A user equipment (UE) may configure timers to be associated with a HARQ ID and a configured grant. A base station or UE may include indicators of the configured grants associated with a HARQ process when exchanging signaling about the HARQ process. A UE may allocate HARQ IDs to multiple configured grants to reduce a likelihood that HARQ processes collide.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for coded-bit allocation for UCI segmentation. An exemplary method that may be performed by a wireless device generally includes generating coded bits of uplink control information (UCI) to be transmitted as one or more segments, applying one or more rules to ensure an integer number of bits are allocated to each of the one or more segments, and transmitting the UCI in the segments according to the assignment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment determine that a physical uplink shared channel (PUSCH) communication, scheduled by an uplink grant, and a physical uplink control channel (PUCCH) communication, corresponding to a physical downlink shared channel (PDSCH) communication scheduled by a downlink grant, are scheduled to overlap in one or more symbols; determine a threshold time based at least in part on an earliest scheduled starting time of the PUSCH communication or the PUCCH communication; selectively multiplex the PUSCH communication and the PUCCH communication based at least in part on whether the uplink grant, the downlink grant, and the PDSCH communication are received before the threshold time; and transmit the PUSCH communication, the PUCCH communication, or both the PUSCH communication and the PUCCH communication based at least in part on the selective multiplexing. Numerous other aspects are provided.

Abstract: According to some examples, a base station may allocate uplink and/or downlink resources (e.g., in the time domain, frequency domain, spatial domain) to user equipment (UEs), or groups of UEs, that may be subsequently reallocated. For example, a base station may determine a reallocation of uplink resources, and may issue a preemption indication (e.g., a cancelation indication) that may correspond to at least a portion of a random access resource. UEs may be configured to monitor for preemption indications and, based on received preemption indications, UEs may determine whether or not to proceed with transmission of a random access message using a random access resource that at least partially overlaps with resources indicated by the preemption indication. For example, a UE may transmit, or preempt transmission of, a random access message based on a preemption configuration of the UE (e.g., configured rules for UE preemption of random access resources).
