    Abstract: Technology to support mapping for Hybrid Automatic Retransmission re-Quest (HARQ) for Carrier Aggregation (CA) is disclosed. One method can include a user equipment (UE) identifying, within a radio frame, a type 2 DownLink (DL) sub-frame within a virtual bundling window associated with a Secondary Component Carrier (SCC). The type 2 DL sub-frame can be virtually moved from a Primary Component Carrier (PCC) for HARQ-ACKnowledge (HARQ-ACK) multiplexing of the virtual bundling window. The UE can extract a Component Carrier Element (CCE) number for a first CCE used by a Physical Downlink Control CHannel (PDCCH) transmission corresponding to the type 2 DL sub-frame. The UE can determine a Physical Uplink Control CHannel (PUCCH) resource for carrying a HARQ-ACK multiplexing message based on the CCE number when a PCC window size of the PCC is greater than an SCC window size of the SCC.

    Abstract: A system and method utilizes a selected PRB configuration for a new carrier type for a 3GPP-type wireless network. A downlink signal is received that comprises a demodulation reference signal pattern in at least one predetermined subframe of the downlink signal. The subframe comprises a first predetermined number of the plurality of orthogonal frequency division multiplex (OFDM) symbols comprising synchronization signals for a legacy version of the downlink signal and the demodulation reference signal pattern comprising a second predetermined number of OFDM symbols that are different from the first predetermined number of the plurality of OFDM symbols. After receiving the downlink signal, the demodulation reference signal pattern in the downlink signal is demodulated.

    Abstract: In embodiments, an eNodeB (eNB) may include a sequence generator to identify an initialization parameter for a pseudo-random sequence. The initialization parameter may have a periodicity greater than one radio frame of a radio signal. The sequence generator may then generated a pseudo-random sequence based at least in part on the initialization parameter, and then generate a reference signal based on the pseudo-random sequence. The eNB may further include a transmitter that is coupled with the sequence generator and is to transmit the reference signal in a subframe of the radio signal.
