Abstract: This disclosure provides methods, components, devices and systems for optimized RACH procedures in NTNs including NB-IoT. A UE performs in an NTN one or more of a first or second procedure in an idle mode, or a third procedure in a connected mode. In the first procedure, the UE considers a number of RAPIDs in msg2, and if the number meets a threshold, the UE applies a backoff to delay sending msg1. In the second procedure, if the UE fails to decode msg2 or msg4 after transmitting msg1, the UE applies a backoff before performing subsequent RACH. In the third procedure, following a failure to receive an uplink grant when monitoring a USS and after transmitting msg1 for a SR, the UE continues monitoring the USS for the grant until the start of a RAR window. If the uplink grant is received during this time, the UE cancels msg2 monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit a data transmission to a receiver. In some examples, the data transmission may be a radio link control (RLC) protocol data unit (PDU) transmission. The UE may store the data transmission in a retransmission buffer, and transmit a feedback request to the receiver in a subsequent data transmission based on a system memory utilization threshold for the retransmission buffer being satisfied due to storage of the data transmission.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced power saving mode (PSM) for an active time duration of a PSM with extended discontinuous reception (eDRX) configuration in a wireless communication system. In one aspect, a user equipment (UE) is configured to enter a deep sleep mode during inactive times of a PSM, and to operate in eDRX mode during the active times of the PSM. Operating in eDRX mode during the active times includes dividing each of the active time durations into at least one eDRX idle period and at least one eDRX paging period. The UE determines whether a set of criteria for implementing a variant of the PSM is met, and when the set of criteria is met, the UE implements the variant of the PSM, which includes powering down the UE to a deep sleep mode at least during eDRX idle periods.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold. The UE may receive, based on transmitting the feedback request message, a feedback response message corresponding to a first previously transmitted uplink packet of the at least one previously transmitted uplink packet.

Numerous other aspects are described.
