Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that a cell associated with the base station does not support reduced capability UEs, wherein the UE is capable of operating in a first mode that is associated with reduced capability UEs and a second mode that is not associated with reduced capability UEs. The UE may communicate, in the second mode, with the base station to establish a connection with the cell based at least in part on at least one of: the UE supporting one or more capabilities associated with connecting with the cell, or no cells that support reduced capability UEs being available. Numerous other aspects are described.

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 user equipment (UE) may establish a wireless connection between the UE and a base station. The UE may identify, in an inactive state for the UE for the wireless connection, data to transmit to the base station. The UE may transmit, in the inactive state, a medium access control protocol data unit, the medium access control protocol data unit comprising both a data packet for the identified data and a request to resume an active state for the wireless connection.

Abstract: The method of wireless communication may include a UE, a base station, and a core network including an AMF. The UE may initiate an update of the paging subgroup ID assigned to the UE by transmitting paging assistance information to the AMF. The paging assistance information may include an expected paging probability of the UE. The base station may initiate an update of the paging subgroup ID assigned to the UE based on the change of RRC connection between the UE and the base station. The core network including the AMF may transmit an updated paging subgroup ID to the UE. The core network including the AMF may configure a set of candidate subgroups associated with the UE, and the base station may update the paging subgroup ID of the UE based on releasing the RRC connection to the RRC inactive state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive radio resource control (RRC) signaling indicating a duration for a timer to be used during a random access channel (RACH) procedure in which the UE transmits mobile-originated uplink data. While in an inactive mode, the UE may transmit the mobile-originated uplink data in a first message of the RACH procedure and the UE may start the timer based at least in part on transmitting the uplink data. The UE may monitor, while in the inactive mode and for the duration of the timer indicated in the RRC signaling, to detect a second message of the RACH procedure including mobile-terminated downlink data in response to the mobile-originated uplink data. Numerous other aspects are provided.

Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

Abstract: Aspects of the disclosure relate to a UE transmitting a request for a discontinuous reception (DRX) cycle of a first duration; receiving an indication that a DRX cycle having a second duration has been assigned to the UE by a core network component; receiving a system information block (SIB) from a base station, the SIB comprising: a default paging cycle, and an indication that override of the default is supported; entering an inactive state in which a transceiver of the UE is in a low power state; and causing, while the UE is in the inactive state, the transceiver to periodically enter a higher power state to monitor its paging channel at a periodicity based on the second duration. Other aspects, embodiments, and features are also claimed and described.

Abstract: Systems, apparatuses, and methods for configurations for small data transmission by which a user equipment transmits, to a base station, user data within a random access message in a radio resource control inactive state. The user equipment may receive, via broadcast system information and/or unicast messages from the base station, a configuration on support capability or parameters for small data transmission. Based on the received configuration, the user equipment may transmit user data to the base station. The user equipment may transmit a random access preamble on a resource separately reserved for small data transmission.

Abstract: Enabling Ethernet Header Compression (EHC) for use with data sent within a Non-Access Stratum (NAS) control plane of a wireless communication network. In one aspect, a wireless communication device sends a signal to a wireless communication network indicating the device supports EHC for data transfer over a control plane. The device obtains a response from the wireless communication network indicating the wireless communication network supports EHC for data transfer over the control plane. The device then sends an Ethernet packet compressed using EHC to the wireless communication network over the control plane. The wireless communication device may be configured to send a request to the wireless communication network to use EHC before sending the Ethernet packet compressed using EHC. The device then sends the compressed Ethernet packet only if the request is granted. In another aspects, complementary EHC features are provided within a network component of the wireless communication network.
