User equipment and evolved node-B supporting machine type communication and small data communication

摘要

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.

1. A User Equipment (UE) configured to operate in a 3rd Generation Partnership Project (3GPP) network in accordance with a communication protocol, the UE comprising hardware processing circuitry, the hardware circuitry comprising:
a memory device; and a processor coupled to the memory device, the processor configured to:
receive from an Evolved Node-B (eNB) a message comprising a Boolean Radio Resource Control (RRC) inactivity timer keep connected support value;transmit a UE radio capability message that is receivable by the eNB and that enables the exchanging of data between the UE and the eNB according to the communication protocol;wherein the UE radio capability message includes:
a small data access parameter that specifies a capability of the UE to exchange small blocks of data with the eNB as part of the communication protocol; anda mobile originating data parameter that specifies a capability of the UE to support a mode in which data to be exchanged as part of the communication protocol originates at the UE;determine whether to operate the UE in a keep connected mode in which the UE operates in an RRC connected state and is restricted from operating in other RRC states;determine whether to adjust a current RRC inactivity timer based on the Boolean RRC inactivity timer keep connected support value and, if so, adjust the current RRC inactivity timer to produce an updated RRC inactivity timer; andtransmit the updated RRC inactivity timer to the eNB.
