Downlink control information response to idle mode requests

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request message to a base station while operating in an idle mode. The base station may generate, in response to the request message, a response message including a random access preamble index corresponding to the received request message. In some cases, the base station may determine a radio network temporary identifier (RNTI) based on the random access preamble index and scramble a cyclic redundancy check (CRC) of the response message with the RNTI. In some examples, the random access preamble index may be included in a payload of the response message. The UE may monitor a physical downlink control channel for the response message to the request message and receive the response message on the physical downlink control channel.
