1. A method for enabling small data transmissions in a user equipment (UE) configured for machine type communication (MTC), the method comprising:
- receiving, by the UE from an evolved node (eNB), a system information block (SIB), the SIB including system information related to small data transmissions for MTC;
reading a small data transmission indicator in the system information included in the SIB;
executing, by the UE, a fast radio resource connection (RRC) with the eNB in response to the small data transmission indicator received from the eNB, wherein the fast RRC connection is executed without the establishment of bearers between the UE and the eNB; and
performing the small data transmission, from the UE to the eNB, based on the system information included in the SIB.

Abstract
Technology for enabling small data transmissions in a user equipment (UE) configured for machine type communication (MTC) is disclosed. One method comprises receiving, by the UE from an evolved node (eNB), a system information block (SIB). The SIB can include system information relating to small data transmissions for MTC. The system information included in the SIB is read by the UE. The small data transmission is performed, from the UE to the eNB, based on the system information included in the SIB.

8. A user equipment (UE) configured for machine type communication (MTC), the UE comprising:
-
a multicast information transfer message module configured to receive a multicast information transfer message, at a user equipment (UE) from an evolved node (eNB), wherein the multicast information transfer message notifies the UE of updated system information in a system information block (SIB) related to small data transmissions by the UE, wherein the multicast information transfer message module is implemented in a first hardware circuit or is comprised of code that is stored in one or more digital memory devices to be executed by one or more processors; a system information block (SIB) module configured to read the updated system information in the SIB when notified of the change in the SIB by the multicast information transfer message from the eNB, wherein the updated system information in the SIB comprises a small data transmission indicator, wherein the system information block (SIB) module is implemented in a second hardware circuit or is comprised of code that is stored in the one or more digital memory devices to be executed by the one or more processors; and a small data transmission module configured to communicate the small data transmission to the eNB by executing a fast radio resource connection (RRC), in response to the small data transmission indicator received from the eNB, wherein executing the fast RRC connection comprises executing a RRC connection setup phase, without an establishment of bearers, between the UE and the eNB and wherein the small data transmission module is implemented in a third hardware circuit or is comprised of code that is stored in the one or more digital memory devices to be executed by the one or more processors. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An evolved node (eNB) comprising:
-
a first hardware circuit configured to receive a multicast information transfer message from a Mobility Management Entity (MME); a second hardware circuit configured to determine a Multicast Radio Network Temporary Identifier (MC-RNTI) used for transmitting the multicast information transfer message to a user equipment (UE), wherein the MC-RNTI is one of a fixed value or a variable value that is derived at the eNB using an International Mobile Subscriber Identity (IMSI) received from the MME; and a third hardware circuit configured to transmit the multicast information transfer message, from the eNB to the UE, based on the MC-RNTI of the UE. - View Dependent Claims (16, 17, 18)

19. At least one non-transitory computer readable medium storing instructions which, when executed by a processor, perform the following operations for enabling small data transmissions in a user equipment (UE) configured for machine type communication (MTC), the operations comprising:
-
receiving, by the UE from an evolved node (eNB), a system information block (SIB) including system information related to small data transmissions for MTC; reading, by the UE, the SIB including a small data transmission indicator in the system information related to the small data transmissions; executing, by the UE, a fast radio resource connection (RRC) with the eNB in response to the small data transmission indicator received from the eNB, wherein the fast RRC connection is executed without the establishment of bearers between the UE and the eNB; and performing the small data transmissions transmission, from the UE to the eNB, based on the system information read by the UE. - View Dependent Claims (20, 21)
