摘要:
Briefly, in accordance with one or more embodiments, if two or more deices belong to a multicast group, a media access control (MAC) message may be transmitted to the multicast group as a multicast message to provide parameters and/or instructions to the devices. If the devices are in an idle mode, the MAC message may be transmitted during a paging listening interval. A group message may be transmitted as a multicast message to one or more devices in one or more groups in order to assign, reassign, or update the group identifier or multiple devices. If an acknowledgment message was not received by one or more the devices, the group message may be transmitted as a unicast message to the one or devices from which no acknowledgment message was received.

A machine type communication interworking function (MTC-IWF) is configured to receive from a service capability exposure function (SCEF), services capability server (SCS), or a third-party application server (AS), application communication pattern information defined by an MTC application and representing characteristics of machine-to-machine (M2M) communications expected from a user equipment (UE) machine type communication (MTC) device. The MTC-IWF being configured to communicate the information to a mobility management entity (MME) that thereby provides core network (CN) originated assistance to an evolved universal terrestrial radio access network node B (eNB). Disclosed are embodiments for providing the information in the form of Diameter-based messages communicated through Tsp, T5, and other interfaces, or through an application programming interface (API) exposed by the SCEF, SCS, or MTC-IWF.

Embodiments of an eNodeB and method for small data transfer in a Wireless Network are generally described herein. A method performed by circuitry of a User Equipment (UE) can include determining, by the UE, whether the UE is configured to be used for Machine Type Communication (MTC). The method can include determining whether the UE has small data (SD) to transfer. The method can include configuring the UE to use a small data signaling radio bearer (SDSRB) to send the SD, in response to determining that the UE is configured to be used for MTC and the UE has SD to transfer. An evolved Node B can determine whether the UE is configured to be used for MTC, determine whether there is SD to transfer to the UE, wherein SD comprises data that has delay tolerance, and configure the UE to use a signaling bearer to send the SD.

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.

Embodiments of a User Equipment (UE) and method for selecting a Radio Resource Control (RRC) inactivity timer for a service operating in a wireless network are generally described herein. In some embodiments, the UE may be configured to operate in a 3GPP network in accordance with a Radio Resource Control (RRC) inactivity timer that controls RRC state transitions of the UE, and further in accordance with a Machine Type Communication (MTC) mode of operation. The UE may receive, from an Evolved Node-B (eNB), one or more messages that may include an RRC inactivity timer keep connected support value that indicates support of a keep connected mode. In some embodiments, when the UE operates in keep connected mode, the UE operates in an RRC connected state and is restricted from operating in other RRC states.

In Machine Type Communication (MTC) with a 3GPP Long Term Evolution (LTE) Network, there is often a need to transmit and receive small data payloads. New information elements (IEs) have been defined to ease the transmission and receipt of small data payloads. Methods and systems can use the new IEs to more efficiently transmit and receive data. The new IEs include a Small Data ACK IE and a Small Data Container IE. Other new messages include an RAC Release indicator and an RRC Connection Release.

Generally, this disclosure provides apparatus and methods for improved signaling of User Equipment (UE) assistance information in a wireless network. The UE device may include a processing circuit configured to generate an assistance information message including a power preference indicator (PPI) and mobility state information (MSI), the PPI and the MSI associated with the UE; a signal generation module configured to generate a Medium Access Control (MAC) layer Control Element (CE) signal, the MAC CE signal including the assistance information message; and a transmitter circuit configured to transmit the MAC CE signal to an evolved Node B (eNB) of a wireless network associated with the UE, the MAC CE signal transmitted on an uplink shared channel (UL-SCH). The assistance information message may also be generated as a Radio Resource Control (RRC) message and transmitted on an uplink dedicated control channel (UL-DCCH).
摘要:
In accordance with some embodiments, a user equipment or mobile station may provide assistance to the eNB or base station so that eNB or base station can more effectively provide settings to the user equipment. Because the user equipment may have more in depth knowledge about the conditions that exist at the user equipment, efficiencies may be achieved by providing information to the eNB from which the eNB can better set various settings on the user equipment, including those related to power saving and latency.

Systems and methods for cell selection and/or reselection based on prioritize nodes are disclosed herein. User equipment (UE) may be configured to determine whether to select and/or reselect an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The eNB may be a dedicated eNB and/or may be communicatively coupled to a dedicated core network (CN). The dedicated eNB and/or the dedicated CN may be configured to optimize performance for UEs sharing particular characteristics. Accordingly, the selection and/or reselection criteria may be biased to encourage the UE to select and/or reselect towards a dedicated eNB and/or an eNB coupled to a dedicated CN. The eNB and/or CN may be dedicated to supporting particular types of UEs, types of nodes, types of traffic, types of subscriptions, UE mobilities, applications/services, other predetermined categories, and/or the like.
摘要:
Devices and methods of enhanced coverage (EC) paging are generally described. An evolved Node-B (eNB) may transmit multiple EC paging messages to user equipment (UE) over at least one paging cycle. Each EC paging message may contain the same paging information. The UE may combine the individual EC paging messages to achieve a predetermined link budget and subsequently may decode the EC combined paging message to determine whether the combined paging message is directed to the UE. The EC paging messages may contain information for more than one UE and a legacy P-RNTI or a specific P-RNTI for EC mode UEs. The EC paging messages may be transmitted in legacy occasions over several paging cycles or non-legacy paging occasions over one or more paging cycles. The EC paging messages may be transmitted in continuous or non-continuous subframes in a particular paging cycle.
