    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: Systems and methods provide solutions for PCell interruption for SCell activation and deactivation. A user equipment (UE) may select the delay of PCell interruption based on the transmission time interval (TTI) and the processing time (e.g., the hybrid automatic repeat request (HARD) processing time). A UE may be configured to process a physical downlink shared channel (PDSCH) comprising an activation command or a deactivation command in a first subframe for an SCell. In response to the activation or deactivation command, based on a TTI length corresponding to the PDSCH, the UE determines the delay for PCell interruption. The delay corresponds to a selected second subframe after the first subframe, wherein a first delay for a first TTI length is longer than a second delay for a second TTI length, and wherein the second TTI length is a shortened TTI (sTTI) compared to the first TTI length.
