Abstract: Aspects relate to compression of messages in a wireless communication system. For messages, such as ACK/NACK feedback in a communication system, messages having an occurrence above or below a certain number of events (e.g., ACK/NACK events) or a probability of the occurrence may be compressed into a single message. By compressing the messages into a single message, the overhead used to transmit such messages may be reduced.

Abstract: Aspects relate to supporting power control for physical uplink control channel (PUCCH) transmissions on an uplink secondary component carrier (SCC) of a wireless communication system. In some aspects, a user equipment (UE) receives a power control configuration from a base station for use by the UE for a PUCCH transmission on a selected uplink SCC. The UE then transmits, based at least in part on the power control configuration, the PUCCH to the base station on the selected uplink SCC. Closed-loop and open-loop power control examples are provided. In some aspects, common or shared power control configurations are provided by the base station for use with each component carrier of a PUCCH group. In other aspects, carrier-specific power control configurations are provided by the base station.

Abstract: Wireless communications systems and methods related to dynamically triggering aperiodic CSI reporting are disclosed. A UE may determine whether a condition is satisfied for triggering upon receipt of a signal from a BS. The condition may be based on a decoding status of the signal. In some examples, the UE may explicitly request a CSI resource signal (e.g., CSI-RS, CSI-IM, or both) from the BS when the condition is met. The explicit request may be included in a modified ACK/NACK field, regardless of whether an ACK or NACK is transmitted. The BS may respond with a CSI resource signal. In other examples, the BS may wait to respond with a CSI resource signal until a threshold number of requests are received from the UE. In other examples, the BS may track a number of NACKs from the UE instead of relying upon an explicit request.

Radio link failure (RLF) of the link may be determined in a wireless device that then transmits a link recovery request (LRR) communicating the RLF and a request for link recovery to a network in a reserved resource in an uplink channel using a second type of link that does not have as high priority (e.g., not as high reliability or as low-latency) as the first type of link, such as enhanced mobile broadband (eMBB). The wireless device receives a grant of uplink resources from the network responsive to the LRR, where the uplink resources are used by the wireless device to transmit an RLF report to the network and are also of the second type of link.
