Enhanced power savings through mobile initiated dormancy

A method for wireless communication at a network device, comprising:

• establishing a radio resource control (RRC) connection with a user equipment (UE) via one or more common control channel (CCCH) transmissions over a signaling radio bearer 0 (SRB 0), wherein establishing the RRC connection comprises a configuration of a signaling radio bearer 1 (SRB 1) associated with dedicated control channel (DCCH) signaling, and wherein the UE is configured for operation in one of a plurality of RRC states comprising a connected state, an inactive state, and an idle state;
• receiving, from the UE via an uplink DCCH over the SRB 1, a message that comprises a field indicative of a connection suspend request, the connection suspend request indicating a request to transition the UE from the connected state to the inactive state;
• determining whether to allow the UE to transition to the inactive state based at least in part on the connection suspend request and the UE being configured for the operation in one of the plurality of RRC states comprising the connected state, the inactive state, and the idle state;
• transmitting, to the UE via a downlink DCCH over the SRB 1, a response to the connection suspend request, the response comprising, based at least in part on an allowance for the UE to transition to the inactive state, a confirmation of the connection suspend request or a denial of the connection suspend request;
• storing a security context and other connection related parameters based at least in part on allowing the UE to transition from the connected state to the inactive state;
• receiving, from the UE, a connection resume request to transition the UE from the inactive state to the connected state;
• and
• transmitting a response to the connection resume request to the UE confirming the connection resume request.

An apparatus for wireless communication at a user equipment (UE), comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors, the one or more memories storing instructions executable by the one or more processors to cause the apparatus to:
• establish a radio resource control (RRC) connection with a network device via one or more common control channel (CCCH) transmissions over a signaling radio bearer 0 (SRB 0), wherein establishing the RRC connection comprises a configuration of a signaling radio bearer 1 (SRB 1) associated with dedicated control channel (DCCH) signaling, and wherein the UE is configured for operation in one of a plurality of RRC states comprising a connected state, an inactive state, and an idle state;
• transmit, to the network device via an uplink DCCH over the SRB 1, a message that comprises a field indicative of a connection suspend request based at least in part on a determination to transition from the connected state to the inactive state, the connection suspend request indicating a request to transition the UE from the connected state to the inactive state;
• receive, from the network device via a downlink DCCH over the SRB 1, a response to the connection suspend request indicating whether the UE is to transition to the inactive state;
• transition from the connected state to the inactive state based at least in part on the response to the connection suspend request;
• store a security context and other connection related parameters based at least in part on transitioning from the connected state to the inactive state;
• and
• transmit, to the network device, a connection resume request to transition from the inactive state to the connected state based at least in part on a determination, while in the inactive state, to resume communications with the network device.
