Abstract:
Embodiments of an enhanced node B (eNB), user equipment (UE) and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the eNB may transmit signaling to indicate D2D discovery zone configuration to proximity service (ProSe) enabled UEs. The signaling may indicate time and frequency resources and a periodicity of a discovery zone and may indicate operational parameters for the discovery zone. The resources of the D2D discovery zone may be allocated for D2D discovery signal transmission by the ProSe-enabled UEs.
Abstract:
Described herein are processes related to discovering and establishing suitable multi-hop communication paths for (endpoint) user equipments (UEs). A network-initiated discovery and path selection processes may utilize periodically transmitted reference signals along with optional assistance information. A network node, such an eNodeB, and other relaying-capable nodes, such as relay UEs, may transmit periodic reference signals. Based on these transmitted reference signals and optional assistance information, the relay UEs and/or an endpoint node (e.g., the eNodeB or the endpoint UE) may make a selection decision for previous hop paths for communication. The endpoint UE or the eNodeB may make the selection decision for the end-to-end path in order to provide coverage extension for the end UE using multi-hop transmission paths.
Abstract:
A technology is disclosed for a user equipment (UE) that is operable to dynamically change an uplink/downlink (UL/DL) configuration in a communications network. A radio resource control (RRC) connection can be requested with an enhanced node B (eNode B). A UE Capability Information information element (IE) can be communicated to the eNode B to indicate an enhanced interference mitigation and traffic adaptation (eIMTA) capability of the UE to support an eIMTA time duplex domain (TDD) UL/DL reconfiguration functionality. An eIMTA configuration information can be received at the UE information within a RRCConnectionSetup message or a RRCConnectionReconfiguration message.
Abstract:
Embodiments of a system and method for reporting uplink control information (UCI) are generally described herein. In some embodiments, a first and second component carrier (CC) is provided for a user equipment (UE). The first and second CC are configured with transmission mode (TM) 10 and TMs 1-9, respectively. A first channel state information (CSI) report for the first CC with TM 10 and a second CSI report for the second CC with at least one of TMs 1-9 are scheduled for transmission in a subframe. A collision is detected between the first and second CSI reports. Priority is assigned to the first CSI report or the second CSI report based on a prioritization parameter. The prioritized CSI report is transmitted based the prioritization parameter.
Abstract:
Generally, this disclosure provides apparatus and methods for improved indication of cell information in a wireless network. The cell information may include an evolved Node B (eNB) carrier type. The UE device may include a receiver circuit configured to receive a Radio Resource Control (RRC) message from an evolved Node B (eNB) of a serving cell, the RRC message comprising carrier information associated with the serving cell eNB; a processing circuit configured to extract, from the serving cell eNB carrier information: a carrier type, synchronization information and Radio Resource Management (RRM) measurement information; a synchronization circuit configured to synchronize the UE to the serving cell eNB based on the synchronization information associated with the serving cell eNB carrier information; and a signal measurement circuit configured to perform RRM signal measurements on the serving cell eNB based on the RRM measurement information associated with the serving cell eNB carrier information.
Abstract:
Techniques to manage heterogeneous carrier types are described. User equipment may comprise a processor circuit and a network control component for execution on the processor circuit to locate a synchronization signal (SS) and a cell-specific reference signal (CRS) in a physical resource block (PRB) pair of a long term evolution (LTE) system, the PRB pair having a physical signal pattern for a first carrier type, the physical signal pattern for the first carrier type to have a same number of defined positions between the SS and the CRS within the PRB pair as a physical signal pattern for a second carrier type. Other embodiments are described and claimed.
Abstract:
Technology for reporting periodic channel state information (CSI) is disclosed. One method can include determining a reporting period (Npd) of a user equipment (UE) for a serving cell. A Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell of the UE can be identified. A periodic CSI report for the serving cell can be transmitted, from the UE to the eNB, using a physical uplink control channel (PUCCH) on the primary cell according to the reporting period. The reporting period of Npd=1 can be used for the serving cell if the TDD UL-DL configuration of the primary cell is one of 0, 1, 3, 4, or 6 and all UL subframes of the primary cell in a radio frame are used for periodic CSI reporting.
Abstract:
Embodiments of a central processing unit and methods for supporting coordinated multi-point (CoMP) transmissions in a 3GPP LTE network with non-ideal backhaul links are generally described herein. In some embodiments, the CPU may be arranged for scheduling and assigning resources for subordinate enhanced node Bs (eNBs) over the backhaul links for CoMP transmissions. The scheduling may include an additional number of HARQ processes to compensate, at least in part, for backhaul link latency.
Abstract:
Generally, this disclosure provides apparatus and methods for improved control channel monitoring in a New Carrier Type (NCT) wireless network. A User Equipment (UE) device may include a receiver circuit to receive a Multicast/Broadcast over Single Frequency Network (MBSFN) for Physical Multicast Channel (P-MCH) transmission from an evolved Node B (eNB); an MBSFN for P-MCH detection module to detect and extract an enhanced physical downlink control channel (EPDCCH) signal from the MBSFN subframe for P-MCH transmission; and an EPDCCH monitor module to decode and monitor the extracted EPDCCH signal.
Abstract:
An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may receive one or more physical broadcast channel (PBCH) signals, dependent on whether the UE is in a normal coverage mode or in one of the EC modes. The PBCH signal may be combined to form a combined PBCH signal, when the UE is in an EC mode, and decoded to determine one of a plurality of sets of resource regions associated different EC modes for communication with the eNB. The signal may be scrambled using a Radio Network Temporary Identifier (RNTI) dependent on at least one of a signal type of the control signal and the EC mode. Paging and the system information block (SIB) signals in a Physical Downlink Shared Channel (PDSCH) may be decoded without decoding a physical downlink control channel (PDCCH) signal associated with the PDSCH.
