Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, at a central unit of the receiving device, information from which the central unit is able to identify a hash calculated based at least in part on a data portion of a message received by a distributed unit of the receiving device. The receiving device may confirm, at the central unit and based at least in part on the hash, an integrity of the data portion of the message. Additionally or alternatively, a distributed unit of the receiving device may confirm the integrity of the data portion of the message. The receiving device may authorize, based at least in part on the integrity confirmation, one or more user plane tunnels with the distributed unit to forward the data portion of the message from the distributed unit to the central unit after processing at the distributed unit.

Abstract: Various features presented herein facilitate early data transmission (EDT) in eMTC and NB-IoT. In certain aspects, a UE (e.g., an eMTC and/or NB-IoT type device), may receive an indication in a SIB from a base station that may enable EDT by the UE. The UE may transmit a random access request based on the SIB. The UE may further receive an MCS index in an RAR, and transmit a connection request (e.g., Msg3) to the base station based on the MCS index and the indication in the SIB. Some aspects described herein relate to an improved rate matching technique. In certain aspects, a UE may be configured to transmit a connection request message to a base station based on at least one of an increased number of RVs than a number of RVs for other transmissions from the UE or rate matching performed across more than one subframe.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a connection release message, the connection release message including a resource indicator indicating that a set of resources are to be used for grant-free uplink transmissions by the UE while operating in a disconnected state. The UE may transition from a connected state to a disconnected state based at least in part on the connection release message. The UE may perform, while operating in the disconnected state, the grant-free uplink transmissions using the set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an autonomous uplink (AUL) transmission to a base station using a configured resource set, the AUL transmission comprising reference signals and data signals. The UE may determine whether a response signal was received from the base station in response to the AUL transmission. The UE may determine whether the response signal indicates that the base station received the reference signals, or the reference signals and the data signals. The UE may select an uplink transmission scheme to use for subsequent transmissions to the base station, the selected uplink transmission scheme based at least in part on the determination of whether the response signal was received from the base station and whether the response signal indicates that the base station received the reference signals or the reference signals and the data signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may measure a physical channel such as a narrowband physical broadcast channel (NPBCH) to supplement (e.g., or as an alternative to) reference signal measurements when determining a received signal measurement, such as a received signal strength or received signal quality of a cell. A base station may transmit an indication to a UE that identifies the frequency at which a portion of NPBCH transmissions (e.g., reserved fields of a master information block (MIB)) is expected to change from one NPBCH transmission to another. The UE may adjust its utilization of NPBCH for determining the received signal measurement based on the indication. Further, the UE may communicate with the cell based on the determination of the received signal measurement, which are based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify first set of metrics associated with a radio link monitoring procedure on a radio link and identify a second set metrics associated with a procedure for monitoring whether communications of a first service type or having a first quality of service requirement are supportable. The UE may monitor the radio link based on the first set of metrics to assess for radio link failure and monitor at least a portion of the radio link based on the second set of metrics. The UE may determine that a component of the radio link fails to satisfy the second set of metrics, and the UE may transmit an indication of the determination to the base station. The UE and the base station may update the radio link without declaring radio link failure.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE) from a base station, a trigger for aperiodic sounding reference signal (SRS) transmission for a group of component carriers (CCs), and selecting for transmission, by the UE and in response to the trigger, one or more SRS resource sets for each CC of the group of one or more CCs. At least one CC has multiple SRS resource sets configured. The UE transmits, to the base station, an SRS on each CC of the group of CCs based on the selecting. Another method of wireless communication includes transmitting, by a base station to a UE, a trigger for aperiodic SRS transmission for a group of CCs. At least one CC has multiple SRS resource sets configured for the UE. The base station receives, from the UE, one or more SRS on each CC of the group of CCs.
