摘要:
Technology for device discovery using a device-to-device (D2D) sounding reference signal (SRS) and device discovery using D2D SRS in a channel measurement group (CMG) is disclosed. In an example, a user equipment (UE) configured for device discovery via a node using the D2D SRS can include a transceiver module. The transceiver module can send a radio resource control (RRC) device discovery request to a node, scan D2D SRS subframes of proximity UEs using D2D SRS triggering, and send feedback to the node of detected D2D SRS information of the proximity UEs. The proximity UE can be located within a same cell as the UE.

Methods, systems, and devices for transmission and reception of SPS communications are disclosed herein. User equipment (UE) 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 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 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 receives the SPS PDSCH in a second subframe. The UE 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 is configured for transmission mode 10 (TM10).

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.

Technology for mitigating edge effect interference in a Coordinated MultiPoint (CoMP) system having multiple CoMP clusters is disclosed. In an example, a method can include a macro node transmitting a cell range expansion request to user equipments (UEs) within a cell. A CoMP cluster for nodes within the cell that includes UEs operating with the cell range expansion can be generated. Blanked resources between a plurality of macro nodes for the CoMP clusters in the CoMP system can be coordinated using a muting preference including a blanked resource.

This disclosure describes systems, methods, and devices related to a trigger-based null data packet (NDP) for channel sounding system. A device may send a trigger frame to a group of station devices, the group of station devices including a first station device, the trigger frame indicating a high efficiency (HE) long training field (HE-LTF) mode and a guard interval duration. The device may identify a HE trigger-based (TB) null data packet (NDP) received from the first station device, the HE TB NDP including a first packet extension field, wherein the HE TB NDP is associated with the HE-LTF mode and the guard interval duration indicated in the trigger frame. The device may send a downlink NDP including a second packet extension field, a second HE-LTF mode, and a second guard interval duration. The device may determine channel state information based on HE TB NDP received from the first station device.
摘要:
Technology for transmitting a distributed control channel element (CCE) for an enhanced physical downlink control channel (ePDCCH) and a localized CCE in a physical resource block (PRB) pair from a node and technology for physical downlink shared channel (PDSCH) physical resource block (PRB) allocation with at least one enhanced physical downlink control channel (ePDCCH) at a wireless device is disclosed. One method can include a node precoding at least one distributed CCE and at least one localized CCE for the PRB pair. The node can transmit the at least one distributed CCE for transmit diversity using at least two user equipment-specific reference signal (UERS) ports and transmitting the at least one localized CCE in the PRB pair. The at least two UERS ports can be used to transmit two CCEs.

This disclosure describes systems, methods, and devices related to a bidirectional location measurement report (LMR) feedback. A responding device may determine a first location measurement report (LMR) feedback type of an initiating device. The responding device may determine a second LMR feedback type of the responding device. The responding device may determine a common availability window, defined by a common start time and a common end time, for an exchange of a first LMR and a second LMR, wherein the common availability window is based on the first LMR feedback type and on the second LMR feedback type. The responding device may cause to send the first LMR to the initiating device during the common availability window. The responding device may identify the second LMR received from the initiating device during the common availability window.
