Data indicator for persistently allocated packets in a communications system

摘要

An apparatus 310 employable in a communication system configured to determine a value for a new data indicator for semi-persistently allocated or scheduled resources. In one embodiment, the apparatus 310 includes a processor 320 configured to receive a cell radio network temporary identifier indicating a semi-persistent scheduling. The processor 320 is also configured to treat a reception of data with a new data indicator flag in accordance with the semi-persistent scheduling as one of a persistent initial transmission if a value of the new data indicator flag is equal to a first predefined value, and a retransmission of semi-persistent scheduling data if the value of the new data indicator flag is equal to a second predefined value.

1. An apparatus, comprising:
a data buffer for storing received data; at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following: receiving a cell radio network temporary identifier indicating a semi-persistent scheduling; and processing a reception of data with a new data indicator flag in accordance with said semi-persistent scheduling as: a semi-persistent initial transmission that initializes one or more semi-persistent transmissions when a value of said new data indicator flag is equal to a first predefined value, and storing parameters when said new data indicator flag is equal to said first predefined value, wherein the one or more semi-persistent transmissions are received without physical downlink control channel according to the stored parameters and wherein the new data indicator flag does not toggle every time new data is received, and a retransmission of semi-persistent scheduling data when said value of said new data indicator flag is equal to a second predefined value, wherein said second predefined value is different than said first predefined value; and modifying said stored data in the data buffer depending on said value of said new data indicator flag.
