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.

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:
In embodiments, apparatuses, methods, and storage media may be described for identifying subframes in a radio frame on which a UE may receive a Physical Downlink Control Channel (PDCCH) or enhanced PDCCH (ePDCCH) transmission. Specifically, the UE may receive multiple indications of uplink/downlink (UL/DL) subframe configurations and identify one or more subframes in which the UE may receive the PDCCH or ePDCCH transmission. The UE may then monitor one or more of the identified subframes and base discontinuous reception (DRX) timer functionality on one or more of the identified subframes.

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for multiplexing channel state information and hybrid automatic repeat request-acknowledgement information. Other embodiments may be described and claimed.
摘要:
Examples are disclosed for timers associated with powering receiver circuitry at a wireless device or user equipment. The examples include separately defining one or more timers based on different time division duplex (TDD) configurations. The different TDD configurations may be used for communications between user equipment and serving cells supported by one or more base stations such as evolved node Bs (eNBs) in a Long Term Evolution (LTE) wireless network. The defined timers may be used by the user equipment to selectively power receiver circuitry. Other examples are described and claimed.
摘要:
Embodiments of a system and method for reporting channel state information (CSI) in a wireless network are generally described herein. In some embodiments, an apparatus of a User Equipment (UE) can include physical layer circuitry to receive, in a first subframe, a first aperiodic CSI request from a first cell group, and a second aperiodic CSI request from a second cell group. The UE can include processing circuitry to determine a number of requested CSI processes corresponding to the first aperiodic CSI request and the second aperiodic CSI request. Additionally, the processing circuitry can select a subset of the requested CSI processes when the determined number of requested CSI processes is more than five. Furthermore, the processing circuitry can calculate CSI for the selected CSI processes.
