1. A method for a user equipment (UE) to receive a downlink data, the method comprising:
- receiving, by the UE, a first downlink assignment including a first new data indicator (NDI) from a base station;
comparing, by the UE, the first NDI to a second NDI;
based on a result of the comparing, determining, by the UE, whether the first NDI has been toggled;
receiving, by the UE, the downlink data based on the first downlink assignment; and
processing, by the UE, the received downlink data based on whether the first NDI has been determined to be toggled,wherein the second NDI is included in a second downlink assignment that was previously received from the base station, andwherein the second downlink assignment was identified by an identifier except for a temporary cell identifier.

Abstract
A method for a user equipment (UE) to receive a downlink signal. The UE receives a first downlink assignment including a first new data indicator (NDI) from a base station. The UE compares the first NDI to a second NDI and, based on a result of the comparison, determines whether the first NDI has been toggled. The UE receives the downlink signal and processes the received downlink signal based on whether the first NDI has been determined to be toggled. Furthermore, the second NDI is included in a second downlink assignment that was previously received from the base station and was not identified by a temporary cell identifier.

8. A user equipment (UE), comprising:
-
a receiver configured to receive a first downlink assignment including a first new data indicator (NDI) from a base station, wherein the receiver is further configured to receive a downlink data based on the first downlink assignment; and a processor operably coupled to the receiver and configured to; perform a comparison of the first NDI to a second NDI, make a determination as to whether the first NDI has been toggled based on a result of the comparison, and process the received downlink data based on whether the first NDI has been determined to be toggled, wherein the second NDI is included in a second downlink assignment that was previously received from the base station, and wherein the second downlink assignment was identified by an identifier except for a temporary cell identifier. - View Dependent Claims (9, 10, 11, 12, 13, 14)
