  • Publication number: 20190253108
    Abstract: A radio network sends downlink signaling to a user equipment (UE) that triggers an enhanced uplink beam selection protocol, based on quality of the UE's uplink signaling the network receives according to a basic uplink beam selection protocol. In response the UE transmits pre-defined signaling such as uplink beam references signals (U-BRS) with uplink beams according to the downlink signaling. The network measures and selects one or more of those uplink beams for the UE to use for sending uplink data, and notifies this selection to the UE. In various embodiments the basic uplink beam selection protocol is based on uplink-downlink reciprocity, the downlink triggering signaling is dynamic and further selects a subset of uplink beams, and multiple UEs can be triggered in common signaling where blind decoding by the UEs is enabled via a scrambling ID for this enhanced uplink beam selection protocol purpose.

  • Patent number: 9847860
    Abstract: There is provided a mechanism for conducting a communication between at least one communication network control element such as an eNB and at least one communication element such as a UE wherein a DM RS based communication mode is used. DMRS (scrambling) sequences are generated wherein each DMRS sequence includes a set of calculation parameters being specific for the respective DMRS sequence, wherein the set of calculation parameters is configurable by the eNB during communication. For initializing each of the at least one scrambling sequence before receiving the configuration information, i.e. in an initial phase of the communication, a predetermined default value based on e.g. an UE_ID and being selectable from a set of predetermined default values is used for the set of calculation parameters in each DMRS sequence.
