摘要： A computer-readable storage medium stores instructions for execution by one or more processors of a UE. The instructions configure the UE for small data transmission (SDT) in a 5G NR network and cause the UE to perform operations comprising detecting while in an RRC_Inactive state, a radio link failure during a first SDT of UL data to a base station. A secure key for a second SDT is generated based on the radio link failure. A configuration message including an indication of the second SDT is transmitted to the base station. A response message including a UL grant is received from the base station. The UL data is encoded for the second SDT using the secure key. The second SDT is performed using the UL grant while the UE is in the RRC_Inactive state.

摘要： Apparatuses of user equipment (UEs) for end-to-end coordination of voice over cellular data network communications. An apparatus of a UE includes one or more data storage devices and one or more processors. The one or more data storage devices are configured to store delay budget information pertaining to end-to-end delivery of a real-time transport protocol (RTP) stream sent from a remote UE to the UE. The one or more processors are configured to generate an application layer message including the delay budget information, the application layer message to be transmitted to the remote UE to enable the remote UE to request, from a cellular base station servicing the remote UE, additional air interface delay based on the delay budget information.

摘要： Apparatuses and methods for control of uplink transmission by a user equipment (UE) using machine-type communications (MTC) applications are described herein. The UE may transmit first data on a logical uplink channel. The logical uplink channel may have been assigned for use by machine-type communications (MTC) applications. The UE may receive transmission time restriction information, responsive to the transmitting, that indicates time periods during which the UE is permitted to transmit additional data on the logical uplink channel. The UE may refrain from transmitting additional data in a time period on the logical uplink channel based on the transmission time restriction information.

摘要： Systems and methods are disclosed for communicating enhanced user equipment (UE) assistance information between nodes in wireless communication systems. The UE achieves power savings and latency requirements more effectively by communicating its preferences, constraints and/or requirements to an evolved Node B (eNodeB) in the form of UE assistance information. The UE assistance information may include, for example, an indication of a preferred set of discontinuous reception (DRX) settings, current data traffic conditions, expected data traffic conditions, power or performance preferences, and/or an indication of the UE's mobility between cells.

摘要： Technology for user equipment (UE) and evolved NobeB (eNB) to support enhanced coverage is disclosed. If both the UE and eNodeB provide support for a first and second coverage enhancement (CE) mode, one or more timers of the UE, eNB and a core network (CN) can 5 be configured according to an extended timer range. However, if either the UE or the eNB does not provide support for both the first and second CE modes, the one or more timers of the UE, eNB and CN are configured according to a legacy timer range.

摘要： Embodiments of user equipment (UE) and base stations (eNodeB) and method for reducing power consumption in UE in a wireless network are generally described herein. In some embodiments, characteristics of UE including mobility, communication data load, and communication type are used by base stations, MME or other controlling entities to configure power saving features of the UE. Power saving features can include a new Radio Resource Control (RRC) layer state where circuitry is powered off for extended periods of time, extended Discontinuous Reception (DRX) cycles, reduced workloads in existing RRC, EPC Connection Management (ECM) and/or EPS Mobility Management (EMM) states or combinations thereof.

摘要： The present disclosure is generally related to wireless and cellular communication, communication system implementations, and in particular, to support for mobile terminated small data transmission (MT-SDT) in 5G systems (5GS). A UE initiates a radio resource control (RRC) resume procedure with a resume cause value of “mt-SDT” in an RRC resume request when a mobile terminated small data transmission (MT-SDT) indication for the UE is included in a received paging message and a set of conditions for initiating MT-SDT have been fulfilled. The UE initiates the RRC resume procedure with a resume cause value of “mt-Access” in the RRC resume request message when the set of conditions for initiating MT-SDT have not been fulfilled. Other embodiments may be described and/or claimed.
