Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method of wireless communication performed by a user equipment (UE) includes receiving, from a base station, a scheduling downlink control information (DCI) message in a physical downlink control channel (PDCCH). The scheduling DCI message indicates a resource allocation for a scheduled DCI message in a subsequent physical downlink shared channel (PDSCH). The method further includes receiving, from the base station, the scheduled DCI message within the subsequent PDSCH. Other aspects and features are also claimed and described.

Abstract: Techniques are described for wireless communication. One method includes detecting a first reference signal received from a user equipment (UE) in a reference scheduled transmission burst including a plurality of contiguous transmission time intervals (TTIs) received over a shared radio frequency spectrum band; identifying a reference TTI in which the first reference signal is received; determining a contention window size usable by the UE to contend for access to the shared radio frequency spectrum band; and transmitting an indication of the determined contention window size to the UE.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

Abstract: Techniques for alternative semi-persistent scheduling (SPS) parameter implementation in association with preemption of use of resources corresponding to other SPS parameters are described. Wireless devices may be implicitly informed with respect to implementing alternative resources corresponding to one or more alternative SPS parameters when use of resources corresponding to first SPS parameters is preempted. A disruption indication (DI), such as used to indicate preemption of downlink transmission on downlink SPS allocated resources and/or a cancellation indication of uplink transmission on uplink SPS allocated resources, may be used to inform (e.g., implicitly) one or more wireless devices to employ alternative resources corresponding to alternative SPS parameters available to the wireless devices. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a user equipment (UE), may include receiving a configuration for reporting feedback associated with beam blocking. The UE may perform a decoding process on one or more downlink transmissions via a set of multiple beams. The UE may determine whether a failure of the decoding process is a result of one or more of the plurality of beams being at least partially blocked during the one or more downlink transmissions according to the configuration. The UE may also transmit a negative acknowledgement (NACK) and link adaptation information, where the NACK acknowledgement is based on the failure of the decoding process and the link adaptation information is based on determining whether the one or more of the set of multiple beams are at least partially blocked.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in a wireless communications system. The UE may receive first control signaling indicating a first radio network temporary identifier (RNTI) and a first feedback process identifier, where the first RNTI indicates scheduling of a unicast downlink transmission. The UE may also receive second control signaling indicating a second RNTI and a second feedback process identifier, where the second RNTI indicates scheduling of a multicast downlink transmission. The UE may manage a hybrid automatic repeat request (HARM) process at the UE associated with the unicast downlink transmission and the multicast downlink transmission based on the first RNTI, the first feedback process identifier, the second RNTI, and the second feedback process identifier. The UE may also simultaneously process multicast downlink transmission and broadcast signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A device such as a user equipment (UE) or a base station may identify a beam switching capability of the UE, the beam switching capability indicating a threshold quantity of beam switches during a transmission time interval, a threshold quantity of symbol periods between beam switching operations, or a combination thereof. The device may determine that the beam switching capability of the UE is satisfied based at least in part on one or more parameters (e.g., one or more symbol period durations, one or more quantities of beam switches during a transmission time interval, one or more adjustment parameters, one or more threshold values associated with the capability of the UE, etc.). The device may perform one or more beam switching operations based on determining that the beam switching capability is satisfied.

Abstract: Various aspects of utilizing narrowband internet of things (NB IOT) communication are still under development. According to an aspect of the disclosure, the apparatus may be a user equipment (UE) for wireless communication via narrowband internet of things (NB IOT) in an unlicensed spectrum using frequency hopping and digital modulation. The UE performs a synchronization with a base station via at least one of a licensed spectrum or the unlicensed spectrum. The UE communicates with the base station based on the synchronization.
