摘要:
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.

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.

Embodiments of apparatus and methods for signaling for resource allocation and scheduling in 5G-NR integrated access and backhaul are generally described herein. In some embodiments, User Equipment configured for reporting a channel quality indicator (CQI) index in a channel state information (CSI) reference resource assumes a physical resource block (PRB) bundling size of two PRBs to derive the CQI index.
摘要:
Technology for supporting dual connectivity is disclosed. A user equipment (UE) may receive a radio resource control (RRC) reconfiguration message from a macro evolved node B (MeNB). The RRC reconfiguration message may indicate that a secondary cell associated with a secondary eNB (SeNB) is to be added for connection to the UE. The UE may complete an RRC reconfiguration procedure to add the secondary cell. The UE may send a preamble to the SeNB indicating that the UE has completed the RRC reconfiguration procedure. The UE may communicate data with the SeNB after sending the preamble to the SeNB, wherein the UE supports dual connectivity to the MeNB and the SeNB.

摘要:
Disclosed herein are methods, apparatuses, and systems for utilizing lightweight communication protocols between different network components. A messaging process is utilized which includes a random access procedure for a user equipment (UE) and an eNodeB, and a messaging sequence comprising a reduced number of messages (compared to a legacy Radio Resource Control (RRC) Connection messaging sequence) exchanged between different nodes of the network to establish a connection. These messages can be generated using any combination of pre-configured or pre-determined data specific to either the UE or to lightweight communication protocols.
摘要:
Methods, systems, and devices for configuration and reporting of proximity detection measurements are disclosed herein. User equipment (UE) is configured to receive and store a PD-RS list from an evolved universal terrestrial radio access network (E-UTRAN) node B (eNB). The PD-RS list includes a radio resource configuration for at least a first proximity discovery reference signal (PD-RS). The UE is configured to measure at least the first PD-RS to determine a signal parameter for the first PD-RS. The UE reports the signal parameter for the first PD-RS to the eNB.

A radio communication device may include a cellular wide area radio communication technology circuit configured to provide a communication according to a cellular wide area radio communication technology; a circuit configured to provide a direct communication device to communication device communication; and a message generator configured to generate a message indicating a request for a handover from an established direct communication device to communication device communication connection with a second radio communication device to a cellular wide area radio communication connection with the second radio communication device.
摘要:
Embodiments of the present disclosure describe systems, devices, and methods for load balancing in a wireless communication network based on user equipment (UE) mobility. In embodiments, a UE may receive a plurality of cell reselection priority configurations designated for different levels of UE mobility. The UE may determine its mobility and select one of the cell reselection priority configurations based on the determined mobility. The UE may establish a radio resource control (RRC) connection, such as an RRC idle mode connection, on a carrier frequency and/or cell based on the selected cell reselection priority configuration. Other embodiments may be described or claimed.
