Abstract:
Technology is discussed for supporting the incorporation of a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS) within in a New Carrier Type (NCT) for a Component Carrier (CC). Guidelines for incorporating the PSS and/or the SSS in the NCT are discovered, together with potential collisions with other signals that can be avoided for various scenarios. In some examples, various guidelines and potential collisions discovered herein, for various scenarios, inform approaches to incorporating the PSS and/or the SSS based on the positioning of the PSS and/or the SSS. In other examples, other signals, such as DeModulation Reference Symbols (DMRS) are reconfigured to allow incorporation of the PSS and the SSS.

Technology for determining a common search space (CSS) from a physical resource block (PRB) indication for a stand-alone carrier type is disclosed. In an example, a user equipment (UE) configured for determining a common search space (CSS) from a physical resource block (PRB) indication for a stand-alone carrier type can include a processing module to: Determine a PRB set in the CSS from an enhanced physical hybrid automatic repeat request (ARQ) indicator channel (ePHICH) configuration information in a master information block (MIB); and decode an enhanced physical downlink control channel (ePDCCH) or the ePHICH from PRB region candidates in the PRB set.
Abstract:
Technology for periodic channel state information (CSI) reporting is disclosed. One method can include a user equipment (UE) identifying a configured CSI reporting instance for a secondary cell to report the periodic CSI to a node based on a CSI reporting configuration of the secondary cell. The UE can determine that the configured CSI reporting instance of the secondary cell used to report the periodic CSI does not correspond with an uplink (UL) subframe of a primary cell. The UE can transmit the periodic CSI report for the secondary cell, to the node, using a physical uplink shared channel (PUSCH) on the secondary cell when the periodic CSI reporting instance for the secondary cell does not correspond with the UL subframe of the primary cell and an UL-SCH (Uplink Shared Channel) is available in a subframe that corresponds to the periodic CSI reporting instance of the secondary cell.

Disclosed in some examples is a method for providing a HARQ response in an LTE network for a PUCCH format 1b. The method includes receiving one or more downlink assignments of a bundling window over a wireless downlink control channel; setting a reception status for each sub-frame of a downlink data channel in the bundling window based on whether the sub-frame on the downlink data channel was associated with a particular one of the received downlink assignments and based upon whether the sub-frame was successfully received; setting a reception status of sub-frames of the downlink data channel in the bundling window that did not have a corresponding downlink assignment to a predetermined value; and transmitting a response, the response based upon the reception statuses set by the response module.
Abstract:
In embodiments, an evolved Node B (eNB) of a wireless communication network may configure an enhanced physical downlink control channel (EPDCCH) physical resource block (PRB) set for a user equipment (UE). The EPDCCH-PRB set may include a plurality of PRB-pairs. The EPDCCH-PRB set may further include a plurality of enhanced resource element groups (EREGs) organized into localized enhanced control channel elements (ECCEs) having EREGs of the same PRB-pair and distributed ECCEs having EREGs of different PRB-pairs. In some embodiments, the eNB may determine a set of distributed EPDCCH candidates for the UE from the EPDCCH-PRB set, wherein the individual distributed EPDCCH candidates include one or more of the distributed ECCEs, and wherein the set of distributed EPDCCH candidates includes at least one EREG from each of the plurality of localized ECCEs. Other embodiments may be described and claimed.
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.

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.
