Abstract: This disclosure provides systems, methods, and devices for wireless communication that support use of common sequence pools for non-coherent transmissions according to one or more aspects. In a first aspect, a method of wireless communication includes converting, by a wireless communication device, an information bit stream to an integer value. The method also includes selecting, by the wireless communication device, a sequence from a common sequence pool based on the integer value. The common sequence pool has a nested structure of sequences which map different length information bit streams with the same most significant bit or bits to the same sequences. The method further includes transmitting, by the wireless communication device, a non-coherent transmission indicating the sequence. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station determines configuration information for a random access procedure, where the configuration information includes a repetition pattern associated with a first message of the random access procedure. A user equipment (UE) receives, from the base station, a configuration message that indicates the configuration information for the random access procedure. The UE determines a repetition pattern associated with a first message of the random access procedure based on the configuration information. The base station receives, from the UE, multiple instances of the first message based on the repetition pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine, based on the downlink configuration, an uplink configuration including a set of resources for transmitting scheduling requests at a set of scheduling request occasions. In some aspects, the set of scheduling request occasions may be arranged according to a non-uniform spacing pattern in the time domain. The UE may transmit, to a base station, one or more scheduling requests based on the uplink configuration.

Abstract: Aspects are provided which allow for multiplexing of higher priority uplink transmissions with lower priority uplink transmissions while maintaining URLLC of the higher priority uplink transmission. A UE receives from a base station information including resources for first and second uplink data, where at least a portion of the resources for the first and second uplink data overlap in time. The first and second uplink data are associated with different priority levels. The UE determines whether to multiplex the uplink data based on a transmission timing difference between a scheduled transmission time and a multiplexed transmission time for the second uplink data on the respective resources. The base station makes a similar determination. If the transmission timing difference fails to meet a delay threshold, multiplexing is performed; otherwise, the lower priority transmission is dropped. Thus, different priority multiplexing may occur in low latency situations, satisfying URLLC.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a dual connectivity configuration for a plurality of communication links, where at least one communication link of the plurality of communication links includes a sidelink. The UE may transmit a report based on an event associated with the sidelink. In some cases, the UE may determine the event associated with the sidelink based on identifying an activation of the at least one additional sidelink carrier, establishing a relay communication link between the UE and a relay network node, measuring a set of path loss values, determining a minimum path loss value of the measured set of path loss values, determining a backoff value for one or more sidelink carriers, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request for sets of neural network weights, each set corresponding to a neural network, to one or more network entities. The one or more network entities may transmit multiple sets of neural network weights to the UE in response to the request. The UE may run a classifier neural network on the sets of neural network weights to select a set of neural network weights corresponding to a neural network. The UE may transmit a neural network identifier to the one or more network entities that transmitted neural network weights.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with a base station using an operating bandwidth part (BWP) that includes a first set of frequency resources. The UE may receive a group-common downlink control information (GC-DCI) message from the base station that includes a resource format indicator (RFI) for the UE (e.g., among multiple RFIs for a set of UEs in the GC-DCI) indicating a second set of frequency resources. The UE may modify the operating BWP based on the second set of frequency resources and communicate with the base station using the modified operating BWP. In some examples, the UE may switch the operating BWP to the second set of frequency resources or may reduce the operating BWP to a set of overlapping frequency resources between the first and second sets of frequency resources.

Abstract: Methods, systems, and devices for wireless communications are described. A base station of a wireless communications system may transmit, to a user equipment (UE), a configuration message that indicates a transmission time interval (TTI) format for a plurality of TTIs. At least one format for the plurality of TTIs includes uplink resources and downlink resources separated in the frequency domain, which may be an example of a subband full duplex (SBFD) slot. Since the pattern may include some transitions between uplink and downlink resources, one or more gap periods (e.g., time gaps) may be positioned between such resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine whether to perform a simplified uplink control information (UCI) multiplexing procedure or select an overlapping uplink channel having the highest priority and drop the remaining overlapping uplink channels. The UE may determine that a first symbol period of the physical uplink scheduled channel (PUSCH) is aligned with a first symbol period of the physical uplink control channel (PUCCH) and the UE may multiplex UCI with an uplink data transmission. The UE may transmit the multiplexed UCI and uplink data on the PUSCH and drop the PUCCH. The UE may perform UCI multiplexing for overlapping PUCCH and PUSCH, located on the same component carrier (CC). The UE may refrain from performing UCI multiplexing if the PUSCH and the PUCCH are located on different CCs, and may simultaneously transmit UCI and uplink data over the different CCs.

Abstract: Methods, systems, and devices for wireless communications are described. A method of wireless communication at a user equipment (UE) is described that may include receiving a data packet transmission over a wireless channel from a base station. The method may further include determining a set of intrinsic log likelihood ratios (LLRs) based at least in part on the data packet transmission and determining an accumulated capacity for the wireless channel based at least in part on the set of intrinsic LLRs. The method may also include determining a channel quality indicator index or a transmission rank for the wireless channel based at least in part on the accumulated capacity and transmitting a feedback message that indicates the channel quality indicator index or the transmission rank for the wireless channel to the base station.
