Dual-connectivity for the User Equipment (UE) in a cellular network is performed by monitoring a plurality of cells. During dual-connectivity, the UE may be simultaneously connected to one serving cell for the Control Plane (C-plane) and to another serving cell, controlled by a different eNodeB, for the User Plane (U-plane). In another embodiment, the dual-connected UE monitors a Physical Downlink Control Channel (PDCCH) from the first eNB and monitors an EPDCCH from the second eNB.

Methods and apparatus for dual connectivity operation in a wireless communication network

Briefly, in accordance with one or more embodiments, apparatus of an evolved NodeB (eNB) comprises circuitry to configure one or more parameters for a 5G master information block (xMIB). The xMIB contains at least one of the following parameters: downlink system bandwidth, system frame number (SFN), or configuration for other physical channels, or a combination thereof. The apparatus of the eNB comprises circuitry to transmit the xMIB via a 5G physical broadcast channel (xPBCH) on a predefined resource, the xPBCH comprising a xPBCH. The xPBCH may use a DM-RS based transmission mode, and a beamformed xPBCH may be used for mid band and high band.

Physical broadcast channel design

Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.

Channel state information (CSI) feedback in a wireless communication system is disclosed. User equipment transmits a CSI feedback signal via a Physical Uplink Control CHannel (PUCCH). If the UE is configured in a first feedback mode, the CSI comprises a first report jointly coding a Rank Indicator (RI) and a first precoding matrix indicator (PMI1), and a second report coding Channel Quality Indicator (CQI) and a second precoding matrix indicator (PMI2). If the UE is configured in a second feedback mode, the CSI comprises a first report coding RI, and a second report coding CQI, PMI1 and PMI2. The jointly coded RI and PMI1 employs codebook sub-sampling, and the jointly coding PMI1, PMI2 and CQI employs codebook sub-sampling.

A user equipment device obtains a first measurement using a first CSI-RS sub-resource and a second measurement using a second CSI-RS sub-resource. The user device derives a single CSI-process based on the first and the second measurements and reports the CSI-process to a base station. The user device receives a message from the base station configuring the first and second CSI-RS sub-resources corresponding to the single CSI-process to be reported by the user device. The message from the base station comprises a configuration of the first CSI-RS sub-resource and a separate configuration of the second CSI-RS sub-resource. The configuration of each CSI-RS sub-resource comprises, for the corresponding CSI-RS sub-resource, at least a CSI-RS sub-resource index, a periodicity, and an offset. The user device may alternatively obtain measurements using any number of CSI-RS sub-resources and then derive and report a single CSI-process based on the plurality of measurements.

Reference signal for 3D MIMO in wireless communication systems

The described technology is generally directed towards operating a user equipment node as a scheduler user equipment (e.g., which can be a local manager of other nodes in a group). The scheduler user equipment receives a scheduling request for the scheduling of the resources for transmission of data by a transmitter user equipment, and based on the traffic type requested, schedules the transmitter user equipment and receiver user equipment(s) with scheduling data/allocated radio resources. The transmitter user equipment can directly transmit to the receiver user equipment(s) on the allocated radio resources, e.g., without further involvement of the scheduler user equipment/local manager. For cellular data, the scheduler user equipment can schedule the transmitter user equipment to transmit to the scheduler user equipment as a receiver node.

Wireless communication framework for multiple user equipment

Aspects of the technology described herein are directed towards using generic control information in a three-party wireless communication system to schedule a data transmission and reception of the data transmission. A scheduler node transmits the generic control information, comprising identification information that identifies a user equipment device as a transmitter node, and scheduling information that schedules a data transmission. For unicast data transmissions, the generic control information further identifies a receiver node, and can schedule transmission of an ACK/NACK from the receiver node corresponding to receiving the data transmission. A control procedure can be configured in a user equipment device by linking a channel configuration dataset to a resource configuration dataset, which in turn is linked to a channel transmit and receive configuration dataset. Reconfiguration is achieved by changing the linking(s) between one or more different available datasets.

Mobile broadband and machine type communication network coexistence

Various embodiments disclosed herein provide for a power control system in a multi-hop integrated access and backhaul network. In the multi-hop integrated access and backhaul network, a donor node can communicate with user equipment devices and relay nodes that have varying power levels; and to avoid receiving uplink transmissions with varying power levels which can impact automatic gain control systems and lower overall throughput, the power control system can manage the power levels of the relay node in order to reduce the difference in power levels. The power control system can schedule relay node devices to transmit uplink transmissions alongside user equipment devices that have a high signal strength; schedule relay nodes and user equipment devices to separate symbols within a time slot; and/or perform closed loop power control management at the relay node to reduce the power level for an uplink transmission.

The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.
