摘要:
Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.

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.

A user equipment (UE) for communication in a wireless network supporting inter-EUTRAN Node B (eNB) carrier aggregation has a receiver to communicate with a first eNB corresponding to a primary cell (PCell) in the wireless network and a second eNB corresponding to a secondary cell (SCell) in the wireless network. The receiver is configured to receive downlink data through a physical downlink shared channel (PDSCH) in the SCell. The UE has a processor configured to, in response to receiving the downlink data, generate a hybrid automatic repeat request acknowledgement (HARQ-ACK) for the SCell. A transmitter of the UE is configured to transmit, through a first physical uplink control channel (PUCCH) in the PCell, uplink control information (UCI) including the HARQ-ACK for the SCell.

A technology that is operable to communicate buffer status report (BSR) information to an evolved node B (eNode B) is disclosed. In one embodiment, a user equipment is configured with circuitry configured to buffer data at the UE for communication to at least one of a master eNode B (MeNode B) or a secondary eNode B (SeNode B). BSR information is determined based on the buffered data at the UE. An uplink split configuration of the UE is determined for the MeNode B and the SeNode B. The MeNode B or the SeNode B is identified based on the uplink split configuration to send selected BSR information. The selected BSR information is communicated to the identified MeNode B or the selected SeNode B.
摘要:
Technology is discussed for self-optimization approaches within wireless networks to optimize networks for energy efficiency, load capacity, and/or mobility, together with new, supporting channel state measurements and handover techniques. New, Channel State Information-Reference Signals (CSI-RSs) for yet-to-be-configured Cell-IDentifications (Cell-IDs) can be used to determine whether adjacent transmission cells can provide coverage for transmission cells that can be switched off for energy efficiency during formation of a Single Frequency Network (SFN). New approaches are also discussed to facilitate mobility within such a network. The new CSI-RSs and mobility approaches can also be used to split up such a SFN when changing load demands so require. Additionally, such new approaches can be used to create a SFN with a common Cell-ID where high mobility is required, such as near a roadway, and to break it up where high capacity is required, such as during a period of traffic congestion.

In some embodiments, a UE is configured to be served by multiple serving cells.

In these embodiments, DRX operations may be performed independently in multiple serving cells belonging to the different eNBs. Other embodiments for enhanced DRX operations are also described.

The security key information may be used to cipher information communicated at the first eNB. A small eNB may be identified at the macro eNB to generate the security key information associated with the macro eNB for ciphering information communicated at the second eNB. The security key information may be communicated, from the macro eNB, to the small eNB for inter-Evolved Universal Terrestrial Radio Access (EUTRA) evolved node B (eNB) carrier aggregation.
