摘要： Systems and methods for reference signal transmission, such as demodulation reference symbol and CSI-RS. The network transmits a reference signal scrambling ID to the UE, and both the network and the UE use this to calculate an initialization sequence for the reference signal. The, one or the other of the network and the UE transmit the reference signal. Optionally, the reference signal is based on a UE-related ID, or a combination of the UE-related ID and one or more other fields.

摘要： In response to receiving a random access channel message from a User Equipment (UE), a network element in a communication network may initiate a random access procedure, for example. The random access channel message includes multiple sequences, such as a first sequence associated with a group of UEs that includes the UE and a second sequence associated with the UE, and may be in any one of multiple different message formats. The random access procedure could include respective search stages for each of the multiple sequences. Power control for random access message transmission is also implemented by the UE in some embodiments.

摘要： User Equipment (UE) mobility in Ultra Dense Networks (UDNs) is based on communication signal layers, which could include respective data streams in an Orthogonal Frequency Division Multiplexing (OFDM) domain, a code domain using respective codebooks, and/or a spatial domain, for example. A UE uses candidate layer decoding parameters in applying layer-based decoding to communication signals that it received from network nodes. Layers could be allocated to UEs and transition between network nodes as UEs move between different network service areas. Layers could instead be allocated to network nodes. Layer-based decoding provides for UE mobility without requiring explicit handover processing every time a UE moves between different service areas.

摘要： Systems and methods are provided for transmit signalling to configure a UE with a UE specific root to use in generating a Zhadoff Chu (ZC) sequence for reference signal transmission. With conventional LTE, a cell specific root is used within each cell. There is a need for a more flexible association between roots and UEs that, for example, allows for multiple roots to be associated with a cell. The provided approach may help with maintaining re-use distance as networks become denser. The method provided in this embodiment improves the capabilities of automatic driving and ADAS of electric vehicles. The method can be applied to vehicle networking, such as V2X, LTE-V, V2X, etc.

摘要： Embodiments of the present disclosure provide mechanisms for the following procedures: network signaling for user equipment (UE) measurements; UE measurements; UE feedback; feedback adjustment at network nodes; scheduling; Acknowledgements/Negative Acknowledgements; and network-wide planning. Some or all of these mechanisms can be used in implementing distributed open-loop multi-user co-operative multi-point (MU-CoMP) technology as well as other non-CoMP, one-tier or centralized wireless transmission technologies. The mechanisms are in line with proposed no-cell technology for 5G communication networks.

摘要： Embodiments are provided to enable distributed open-loop multi-user co-operative multi-point (MU-CoMP) scheduling and transmission. In an embodiment, network nodes schedule data transmissions for UEs among multiple transmission tiers that include a first transmission tier having predetermined modulation and coding and a second transmission tier having adaptive modulation and coding. The first transmission tier and the second transmission tier are in respective time-frequency resources that at least partially overlap. The network nodes transmit the scheduled data transmissions in the transmission tiers according to the scheduling for the UEs. A UE receives CoMP transmissions once it is scheduled for transmission by multiple network nodes.

摘要： Methods and devices for assigning sounding reference signals (SRS) resources to UEs in a wireless communication network are provided. Configuration information is sent to a UE, the configuration information pertaining to a first sequence identifier (ID) to be used by the UE to generate a plurality of SRS sequences to be sent by the UE as at least part of a first SRS. Each SRS sequence of the plurality of SRS sequences is a function of a respective SRS sequence root that is a function of the first sequence ID. The first sequence ID may be a UE-specific sequence ID that is a function of a UE-specific ID associated with the UE, such as a Cell-Radio Network Temporary Identifier (C-RNTI).

摘要： Methods and devices for uplink-based User Equipment (UE) tracking for UEs operating in a connected inactive operating state are provided. A transmit-receive point (TRP) transmits parameters to a UE that allow the UE to uniquely determine a UE-specific tracking sequence and assigned time-frequency (TF) resource that are independent of a TRP identifier associated with the TRP. The UE determines the UE-specific tracking sequence and assigned TF resource based at least in part on the parameters received from the TRP. While in the connected inactive operating state, the UE transmits a tracking signal that includes the UE-specific tracking sequence in accordance with the assigned TF resource. The TRP receives the tracking signal from the UE, detects the UE in accordance with the UE-specific tracking sequence to produce a UE detection status, and transmits a tracking response to the UE in accordance with the UE detection status.

摘要： Antenna beam sweeping according to the present disclosure involves different communication devices that are within an interference range of each other transmitting beam sweeping signals using different communication resources. This allows a receiver to distinguish between beam sweeping signals that are received from different transmitters, and may facilitate antenna beam alignment in multi-connection scenarios. Beam indices could be used to identify antenna beams for antenna beam management, in control signaling between base stations and User Equipment (UE), for example. Beam tracking and other aspects of antenna beam management are also disclosed.
