A User Equipment (UE) device operates to directly determine a target small cell for access or handover with the assistance of a macro cell network. The UE directly generates the connection and selects which small cell to access from among a subset of small cells chosen of a set of candidate small cells. The UE is provided dedicated assistance information from the evolved node B (eNB) or macro network device. The dedicated assistance information enables the UE to measure data from the candidate small cells within a heterogeneous network environment. The UE shares the measured data and connects directly to the selected small cell for an access or handover operation.

Described is a fallback mechanism to detect Enhanced Coverage (EC) usage. A User Equipment (UE) may include an antenna, a measuring circuitry, and a decoding circuitry. The fallback mechanism may be triggered by receipt of a message from an Evolved Node-B (eNB), or determination that a Cell Selection criteria has been satisfied, or successful decode of a predetermined number of predetermined messages. Upon a triggering event, and when an EC level reliability indicator is asserted, the measuring circuitry may measure a parameter of a Cell-Specific Reference Signal (CRS) received by the antenna, such as an RSRP or an RSRQ. Otherwise, upon the triggering event, and when the EC level reliability indicator is de-asserted, the decoding circuitry may monitor for successful decode of a transmission received by the antenna, or for successful decode of a predetermined number of transmissions received by the antenna.

A network device (e.g., an evolved Node B (eNB) or user equipment (UE)) can process or generate a measurement gap pattern to enable network measurements of carriers or bands during measurement gaps on a per component carrier (CC) basis. The transmitting or receiving of the measurement objects (e.g., carriers or band) communicatively coupled on the network and the measurement gap pattern can be communicated via one or more radio resource control (RRC) signals, and re-configured according to a supporting CC data set identifying one or more criteria related to each CC such as UE capabilities, associations of the UE capabilities to measurement gap configurations, types of measurement gap period / gap offsets, different measurement gap patterns, an absence of a measurement gap, or other criteria related to CCs, respectively. In response to the supporting CC data set, measurement gap patterns can be dynamically re-configured per CC.

A network device (e.g., an evolved Node B (eNB) or user equipment (UE)) can identify a measurement object identifier and a measurement gap pattern to enable network measurements of carriers or bands during measurement gaps. The measurement object identifiers can be increased for release 13 or beyond. Measurement gap patterns can be communicated in order to reduce the measurement delay as well as increase data efficiency in the downlink.

Embodiments of the present disclosure describe methods, systems, and devices for facilitating transfer of user equipment (UE) handover in multi-cell networks. A source evolved node B (eNB) may transmit an autonomous handover grant to a UE along with an indication of a target eNB. The source eNB may also make a handover request to the target eNB and provide a UE context to the target eNB. Upon transmission of a handover command, the UE may perform a random access channel procedure to connect to the target eNB. Because the eNB may have the UE context (or may be able to fetch the context), the handover time may be lessened. Other embodiments may be described and/or claimed.

Described herein are processes related to discovering and establishing suitable multihop 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.

Systems and methods for signaling in an increased carrier monitoring wireless communication environment are disclosed herein. In some embodiments, a user equipment (UE) may include control circuitry to configure the UE for increased carrier monitoring; determine, based on a first signal received from a network apparatus, whether a reduced performance group carrier is configured; determine, based on a second signal received from the network apparatus, whether a scaling factor is configured; and in response to a determination that no reduced performance group carrier is configured and a determination that no scaling factor is configured, allow the UE to monitor fewer carriers than required by increased carrier monitoring. Other embodiments may be disclosed and/or claimed.
