Soft Combining is an error correction technique in which the bad packets are not discarded but stored in a buffer. The basic idea is that 2 or more packets received with insufficient information can be combined together in such a way that total signal can be decoded. HARQ procedure is as fo...

Effect of RACH Procedure on the Performance of LTE- based M2M Communication In this paper, the parameters of the Random Access Channel (RACH) of LTE/ LTE-A based M2M communication under congestion situation are investigated. These parameters include the effect of the Backoff Indicator (BI), Hyb...
the RRC field may have a single value which, if the RRC field is present, indicates the NcellsDLparameter in the Type-3 CB construction procedure is equal to the number of all activated DL cells. Otherwise, the NcellsDLparameter in the Type-3 CB construction procedure is equal to the numb...

The processing circuitry is configured to: send and receive data through the at least one antenna, in response to failing to decode a transport block transmitted by a first downlink carrier, transmit a negative acknowledgement message to the base station, and receive a re-transmission of the ...
Shown in some examples is a procedure to provide a HARQ response in an LTE network for a PUCCH format lb. The procedure includes receiving one or more sub-link assignments for a sub-loop window via a wireless sub-loop control channel, set a reception status for each sub-area of a sub-...
