  • Publication number: 20200412513
    Abstract: Example methods and apparatuses provide for the advantageous use of “first” and “second” indicators for cell state control with respect to a wireless communication device. When sent singularly, the first indicator indicates activated/deactivated state transitions according to corresponding sequential state transition logic implemented in the device, and the second indicator indicates activated/dormant state transitions according to corresponding sequential state transition logic implemented in the device. When sent Jointly for a given serving cell of the device, the first and second indicators operate as a combinational pair that indicates what the operational state of the cell shall be for the device, irrespective of the current cell state.

    Abstract: A method for generating a probability map for a cell served by a network node is provided. The method includes generating a first probability map (P1) indicating a likelihood of primary beam directions (step 602). Generating the first probability map includes recording a first direction of a first user equipment (UE), the first direction indicating a direction of a first beam (e.g., a first set of antenna weights (a.k.a., precoding vector)) associated with the first UE when the first UE appears in the cell served by the network node. The method further includes generating a second probability map (P2) indicating a joint likelihood of primary and secondary beam directions (step 604). Generating the second probability map includes recording a second direction of a second beam associated with the first UE when the first UE switches from the first beam to the second beam, the second direction being recorded in association with the first direction.

  • Publication number: 20200187196
    Abstract: A wireless device (e.g., UE) and a method implemented by the wireless device are described herein where the wireless device is configured with resources for both Physical Uplink Control Channel (PUCCH) and short PUCCH (sPUCCH), and determines whether or not the sPUCCH performance is equal to the PUCCH performance, and based on a result of the determination applies a strategy for determining when to trigger a fallback where the strategy is based on a number of failed Scheduling Request (SR) transmissions to a wireless access node (e.g., eNB, eNodeB, ng-eNB, gNB). A wireless access node and method implemented by the wireless access node are also described herein.

  • Publication number: 20200163109
    Abstract: According to the present disclosure, behaviors of User Equipment (UE) and base station (BS) pertinent to Scheduling Request (SR) and/or Buffer Status Report (BSR) as well as resource management in short Transmission Time Interval (sTTI) relevant scenarios are discussed. UE may firstly determine if the SR is triggered by a buffer status change of a delay-critical data which needs a sTTI. If so, UE will send the SR to BS on a first type of uplink control channel designed for sTTI. Otherwise, UE will send the SR to the base station on a second type of uplink control channel designed for legacy TTI.
