Abstract: Methods, systems, and devices for wireless communication are described. Wireless devices may operate in an extended connected discontinuous reception (eDRX) mode to increase energy efficiency and extend battery life. Control signaling may be used to initiate or support the extended sleep cycles associated with eDRX operation. In some cases, a system frame number (SFN) extension may be implemented to record frame cycles and differentiate SFNs that occur in a first frame cycle from SFNs that occur in a second frame cycle. Control techniques to support eDRX operation and maintain network synchronicity and compatibility may also be employed. In some examples, a wireless system may broadcast extended or dedicated system information updates to an eDRX capable device or devices. In some cases, devices may adjust the rate at which radio link monitoring (RLM) measurements are taken to timely determine radio link failures (RLFs) in conjunction with eDRX operation.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may receive a control signal from a base station on resources of a first narrowband region. The UE may then identify a second narrowband region based on the control signal. In some cases a broadband carrier may be divided into an indexed set of narrowband regions, and the UE may identify an index using information contained in (implicitly or explicitly) in the control signal. The UE may communicate with the base station on resources of the second narrowband region. For example, a UE may receive a system information block (SIB) or a paging message, and perform a random access procedure using narrowband resources selected based on the SIB or paging message.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may directly send small data to a disaggregated base station without performing a random access procedure. The CU-CP may provide a list of routing identifiers and corresponding data resource bearers (DRBs) to a distributed unit (DU) and the DU may transmit a connection release message to the UE. The connection release message may include the list of routing identifiers and the list of DRB identifiers. The connection release message may also include a downlink monitoring timer. The UE may identify data for an uplink transmission and a DRB associated with that data. The UE may transmit a packet with the data and the routing identifiers to a DU, which may derive downlink address information from the routing identifiers and forward the data to a CU-UP of the aggregated base station.

Abstract: Methods, systems, and devices for wireless communications are described. A multicast architecture may support flexible change between unicast and multicast operations and may support additional traffic types (e.g., Internet Protocol and Ethernet traffic). For example, the multicast architecture may include transmitting data over a shared multicast radio bearer (MRB) and/or specific data radio bearers (DRBs), a multicast user plane function (UPF) for supplying the multicast data to a base station, multicast data from different radio access networks (RANs), protecting the multicast data through creating a group key, ciphering the multicast data sent on the MRB using the group key, and transitioning the multicast data from a source RAN to a target RAN.

Abstract: Methods, systems, and devices for wireless communications are described. A first base station may identify that the first base station is a secondary node for a user equipment (UE) operating in a dual connectivity deployment, where the UE is in a radio resource control (RRC) inactive state. The first base station may receive, from the UE, a request to resume communications with the first base station and a second base station that is a master node in the dual connectivity deployment. The first base station may verify the UE using an access stratum context associated with the UE, and resume communications with the UE based at least in part on the request and the access stratum context. The first base station may resume communications as a secondary node or as a master node. In some cases, the UE may resume communications without entering an RRC idle state.
