Abstract: A wireless device may identify a set of resources reserved for feedback information (e.g., resource elements (REs) reserved for feedback such as acknowledgement (ACK) or negative ACK (NACK) information) within a transmission time interval (TTI). Feedback information may be mapped to the reserved set of resources (e.g., reserved REs). The wireless device may determine a set of unused reserved resources (e.g., a set of unused reserved REs) based on the number of feedback bits. The wireless device may then map other bits (e.g., zeros, known bits, pattern or sequence of bits, random bits, etc.) to the set of unused reserved REs, or boost transmission power of bits mapped around the unused reserved REs. In some cases, the number of reserved REs may be determined based on the number of feedback bits (e.g., the size of the ACK/NACK payload). The wireless device may then transmit the information to a base station.

Abstract: Methods, systems, and devices for wireless communications are described. A device (e.g., a base station or a user equipment (UE)) may identify a sequence length corresponding to a number of resource blocks, and select a modulation scheme based on the sequence length. The device may select, from a set of sequences associated with the modulation scheme, a sequence having the sequence length. In some examples, the set of sequences may include at least one of a set of time domain phase shift keying computer-generated sequences or a set of frequency domain phase shift keying computer-generated sequences. The device may generate a reference signal for a data transmission based on the sequence and transmit the reference signal within the number of resource blocks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify a collision between a first resource for a downlink semi-persistent scheduled communication and a second resource for another downlink signal; and perform an action to mitigate the collision based at least in part on identifying the collision. In some aspects, a user equipment (UE) may identify a collision between a first resource for a downlink semi-persistently scheduled (SPS) communication and a second resource for another downlink signal; and determine an action, to be performed by a base station, to mitigate the collision based at least in part on identifying the collision; and selectively receive the downlink SPS communication or the other downlink signal based at least in part on the determination. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink data transmission scheduled for transmission by the UE in a first transmission time interval overlaps with multiple uplink control transmissions also scheduled for transmission by the UE during corresponding second transmission time intervals that are shorter in duration than the first transmission time interval. The UE may determine that the multiple uplink control transmissions satisfy a scheduling constraint that is based at least in part on an uplink control transmission type of the multiple uplink control transmissions that overlap with the uplink data transmission. The UE may transmit the uplink data transmission and the multiple uplink control transmissions based at least in part on the scheduling constraint being satisfied.

Abstract: Techniques and devices for wireless communications are described to support communication over multiple component carriers using configured resources. A base station may identify a resource configuration for one or more sets of configured resources for communication with a user equipment (UE) and may indicate the resource configuration to the UE. The base station may transmit a downlink control message to the UE that includes a field to indicate one or more sets of resources that are to be activated or deactivated. The UE may receive the downlink control message and, based on the downlink control message, may identify the one or more indicated sets of resources. The UE may determine, based on the downlink control message, whether the one or more sets of resources is activated or deactivated. The UE and the base station may communicate based on the one or more activated or deactivated sets of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a configuration of a radio link monitoring resource for a radio link that transports downlink traffic for a first type of service, the first type of service having a higher reliability specification and a lower latency specification than a second type of service offered by the base station. The UE may receive the configuration, and detect that the radio link satisfies a failure condition for the first type of service based on monitoring the RLM resource. The UE may transmit a radio link failure (RLF) indication for the first type of service to the base station based on detecting that the radio link satisfies the failure condition for the first type of service. The base station may receive the RLF from the UE, and transmit an RLF response to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may identify a capability for downlink control channel monitoring and uplink cancellation indication monitoring. The UE may transmit, to a base station, an indication of the identified uplink cancellation indication monitoring capability. The base station may receive the indication from the UE, and may configure monitoring occasions in a slot based on the received uplink cancellation indication monitoring capability. The base station may transmit via radio resource control signaling, and the UE may receive, a configuration which configures a number of monitoring occasions based on the uplink cancellation indication monitoring capability. The UE may then monitor the configured monitoring occasions according to the identified capability.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure uplink resources within a slot to enable a user equipment (UE) to transmit an acknowledgment (ACK) feedback message for multiple downlink semi-persistent scheduling (SPS) configurations. For example, the base station may transmit an additional configuration to the UE that indicates uplink resources that the UE can use to transmit acknowledgment feedbacks for multiple downlink messages received according to the SPS configurations, where the UE determines which uplink resource to use based on a number of acknowledgment information bits to be transmitted for the acknowledgment feedback message. For example, if the number of acknowledgment information bits is below a threshold value, the UE may use a first uplink resource configured by the base station. Alternatively, if the number of acknowledgment information bits is above the threshold value, the UE may use a second uplink resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a random access preamble to a base station as part of a two-step random access procedure. The UE may generate the preamble by identifying a discrete Fourier transform (DFT) matrix and generating a set of sequences based on the DFT matrix. Each sequence of the set of sequences may be generated by selecting a column of the DFT matrix and performing deterministic sampling of respective entries from the selected column in accordance with a sampling function. The UE may then select a sequence from the set of sequences based on generating the set of sequence. The UE may transmit the selected sequence to a wireless device (e.g., a base station).
