Abstract
A device, system and method for determining when to initiate certain operations associated with received data. The method is performed at a device connected to a network. The method includes estimating a first number of repetitions of a subframe which is associated with a likelihood that the device will successfully perform an operation based on the subframe. The method further includes delaying initiating the operation for the subframe until a received number of repetitions of the subframe is greater than or equal to the first number of repetitions.
Claims27
A method, comprising:
- at a user equipment (UE):
- estimating a first number of repetitions (Ns) of a subframe which is associated with a likelihood that the UE will successfully perform an operation based on the subframe;
- and
- delaying initiating the operation for the subframe until a received number of repetitions of the subframe (Nr) is greater than or equal to the first number of repetitions (Ns).
A user equipment (UE), comprising:
- a transceiver configured to establish a connection with a cell;
- a baseband processor connected to the transceiver and configured to perform operations comprising:
- estimating a first number of repetitions (Ns) of a subframe which is associated with a likelihood that the UE will successfully perform an operation based on the subframe;
- and
- delaying initiating the operation for the subframe until a received number of repetitions of the subframe (Nr) is greater than or equal to the first number of repetitions (Ns).
A method comprising:
- at a user equipment (UE):
- determining a number of repetitions of a subframe to be received by the UE, wherein each of the repetitions of the subframe includes a plurality of OFDM symbols;
- when the number of repetitions is equal to one, determining whether to initiate an operation based on receiving all the OFDM symbols of the subframe or a portion of the OFDM symbols of the subframe, wherein the operation is one of a channel estimation or a demodulation;
- and
- when the number of repetitions is greater than one, determining whether to initiate the operation based on receiving all the OFDM symbols of the number of repetitions of the subframe or less than all of the OFDM symbols of the number of repetitions of the subframe.
A user equipment (UE), comprising:
- a transceiver configured to establish a connection with a cell;
- a baseband processor connected to the transceiver and configured to perform operations comprising:
- determining a number of repetitions of a subframe to be received by the UE;
- and,
- wherein each of the repetitions of the subframe includes a plurality of OFDM symbols;
- when the number of repetitions is equal to one, determining whether to initiate an operation based on receiving all the OFDM symbols of the subframe or a portion of the OFDM symbols of the subframe;
- and
- when the number of repetitions is greater than one, determining whether to initiate the operation based on receiving all the OFDM symbols of the number of repetitions of the subframe or less than all of the OFDM symbols of the number of repetitions of the subframe.
