Abstract: Embodiments allow selection of a Discovery signal (DS) used to identify an eNB to a UE receiving the DS. The DS allows the UE to ascertain the existence and/or cell identifier of the eNB. DS comprise a plurality of other signals such as a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Cell Specific Reference Signal (CRS) and/or a Channel State Information Reference Signal (CSI-RS). A DS occasion comprises a number of subframes where the selected signals that comprise the DS are transmitted. The signals selected for the DS, their characteristics and properties allow a UE to decode the cell identifier. The DS occasion occurs with a designated periodicity.

Abstract: A user equipment, UE, (400) includes a transmission mode component (402), a selection component (406), and a transmission component (408). The transmission mode component (408) is configured to selectively allocate resources for device-to device communication according to a plurality of transmission modes. The plurality of transmission modes include a first transmission mode in which the resources used by the UE (400) are specifically allocated by one of a base station or relay node and a second transmission mode in which the UE (400) selects the resources from a pool of available resources. The selection component (406) is configured to select a selected transmission mode. The transmission component (408) is configured to transmit signals in frequency resources selected according to the selected transmission mode. Figure 1

Abstract: Methods, systems (100), and devices for transmission and reception of SPS communications are disclosed herein. User equipment, UE, (102) is configured to receive, in a first subframe, a physical downlink control channel or enhanced physical downlink control channel, PDCCH/EPDCCH, corresponding to semi-persistent scheduling, SPS, activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE (102) configures, based on the SPS activation, a downlink, DL, assignment in a second subframe for receiving an SPS physical downlink shared channel, PDSCH, without a corresponding PDCCH/EPDCCH. The UE (102) determines a reference signal sequence corresponding to the SPS PDSCH using nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE (102) receives the SPS PDSCH in a second subframe. The UE (102) processes the SPS PDSCH based on the reference signal sequence for the SPS PDSCH in the second subframe using the nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE (102) is configured for transmission mode 10, TM10.

Abstract: Technology for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH) is disclosed. In an example, a user equipment (UE) can include a processor configured to: Recursively attempt to decode the DCI from enhanced control channel elements (ECCE) of the EPDCCH from physical resource block (PRB) region candidates in a PRB set using a selected set of enhanced resource element group (EREG) index maps for the ECCE until the DCI is successfully decoded; and decode the DCI with an EREG index map associated with a same aggregation level used to encode the DCI. Each EREG index map can be configured for a different aggregation level (AL).

Abstract: Technology for performing indexing on localized enhanced control channel elements (eCCEs) and distributed eCCEs for ePDCCH in a radio frame is disclosed. One method comprises indexing localized eCCEs and distributed eCCEs independently based an aggregation level for an enhanced physical downlink control channel (ePDCCH) transmission. For example, physical indexes of the localized eCCEs may be indexed in frequency increasing order while the indexing is aggregation level specifically mapped to physical indexes. For distributed eCCEs, the logical indexing may further take inter-cell interference (ICIC) coordinate region into consideration. The eCCE indexes belonging to the search space for a given aggregation level (AGGL) may distribute across different ICIC coordinate regions. Further, an AGGL specific global logical indexing may be applied to localized eCCEs and distributed eCCEs with the logical indexes for localized eCCEs and distributed eCCEs interleaved with each other. The ICIC region may also be considered in the global indexing. The AGGL specific eCCE indexing can be used for ePDCCH assignment and blind decoding and/or resource allocation for ePDCCH. The physical eCCE indexes can be used for implicit index derivation for a physical uplink control channel (PUCCH).
