Small data transmission in a wireless communications system
First Claim
1. A method for wireless communication, comprising:
- receiving, at a base station from a network node, a paging request associated with a user equipment (UE), wherein the paging request comprises a small data packet, wherein the small data packet comprises user Internet Protocol (IP) data transferred via a serving gateway;
transmitting a page to the UE;
receiving a random access preamble from the UE responsive to the page; and
transmitting the small data packet in a random access response to the UE responsive to the random access preamble, wherein the random access response comprises a first field for a timing advance, a second field for an uplink grant, and/or a third field for a cell radio network temporary identifier (C-RNTI), and wherein the small data packet replaces the first field for the timing advance, the second field for uplink grant, and/or the third field for the C-RNTI in the random access response.

Abstract
Techniques are provided for transmission of small data packets through a paging procedure in a MTC or cellular internet of things system (CIoT). A core network may receive data to be transmitted to a user equipment (UE) and may determine that a small data packet transmission may be initiated for the data. The core network may format the small data packet into a paging request that includes the data and a UE identification, and transmit the paging request to a base station. The base station may receive the paging request, and initiate a page process with the UE. The UE may receive a page message, and initiate an access procedure that may be used for transmission of the small data. The UE may be in idle mode prior to the small data transmission, and in some examples may return to idle mode following the transmission of the small data.

6. A method for wireless communication, comprising:
-
receiving, at a user equipment (UE), a page from a base station; initiating a random access procedure by transmitting a random access preamble to the base station responsive to the page; receiving a small data packet in a random access response from the base station, the random access response responsive to the random access preamble, wherein the small data packet comprises user Internet Protocol (IP) data transferred via a serving gateway, and wherein the random access response comprises a first field for a timing advance, a second field for an uplink grant, and/or a third field for a cell radio network temporary identifier (C-RNTI), and wherein the small data packet replaces the first field for the timing advance, the second field for uplink grant, and/or the third field for the C-RNTI in the random access response; and acknowledging the small data packet. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus for communication, comprising:
-
a processor; memory in electronic communication with the processor; and instructions stored in the memory; wherein the instructions are executable by the processor to; receive, at a base station from a network node, a paging request associated with a user equipment (UE), wherein the paging request comprises a small data packet, wherein the small data packet comprises user Internet Protocol (IP) data transferred via a serving gateway; transmit a page to the UE; receive a random access preamble from the UE responsive to the page; and transmitting the small data packet in a random access response to the UE responsive to the random access preamble, wherein the random access response comprises a first field for a timing advance, a second field for an uplink grant, and/or a third field for a cell radio network temporary identifier (C-RNTI), and wherein the small data packet replaces the first field for the timing advance, the second field for uplink grant, and/or the third field for the C-RNTI in the random access response. - View Dependent Claims (12, 13, 14, 15)
