  • Publication number: 20210211928
    Abstract: Provided herein is an apparatus and a method for congestion handling in RAN. The disclosure provides an apparatus for a relay node in a RAN including the relay node and a donor node providing an interface to a core network and a backhaul link to the relay node. The apparatus includes a RF interface to receive and transmit downlink data for one or more UEs or UE bearers; and a processing circuitry coupled with the RF interface. The processing circuitry is to determine a downlink congestion occurs at the relay node; and generate a downlink congestion indication to identify a UE or a UE bearer or a backhaul RLC channel affected by the downlink congestion. The RF interface is to transmit the downlink congestion indication to the donor node. In addition to the downlink congestion handling, the relay node can also be to handle uplink congestion in a similar way.

The set of CSI-RS resources may include a plurality of one-port CSI-RS resources configured according to the CSI-RS configuration. The CSI-RS configuration may specify a quasi co-location (QCL) configuration including a set of QCL parameters, where a demodulation reference signal (DMRS) has a QCL relationship with the RS with respect to the set of QCL parameters. The network controller may signal the one or more CSI-RS configurations to UEs.

  • Patent number: 10980064
    Abstract: An efficient random access procedure is provided for reduced control overhead of connections in random access systems. A base station transmits one or more synchronization signal (SS) blocks. A UE detects and determines a preferred SS block. The UE transmits multiple random access signals (e.g., PRACH signals) in a RACH occasion. Each PRACH signal is transmitted on a different beam and includes a RACH preamble. The base station receives one or more of the PRACH signals. The RACH occasion and optionally the RACH preamble identify the preferred SS block. The base station determines a preferred PRACH signal. The base station sends a RAR to the UE using the transmit beam of the preferred SS block. The RAR indicates the preferred PRACH signal and an uplink resource allocation. The UE receives the RAR and transmits a message using the transmit beam of the preferred PRACH signal and the uplink resource allocation.

  • Publication number: 20200322108
    Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.

  • Patent number: 10542464
    Abstract: It is possible to reduce latency and/or overhead when performing a platoon handover by using the leading vehicle in the platoon to communicate handover requests and/or initial resource requests (e.g., random access transmissions) on behalf of trailing vehicles in the platoon. In one example, a leading vehicle in a platoon communicates a handover request to a source AP to request handover of the entire platoon from the source AP to a target AP. In such an example, the source AP then communicates handover commands to each vehicle in the platoon without receiving separate handover requests from the trailing vehicles, thereby reducing overhead in the access network. The handover commands notify the trailing vehicles of the handover, and may be sequentially communicated to the trailing vehicles based on their order in the platoon.
