  • Patent number: 11638286
    Abstract: In some implementations, a method of wireless communications between a wireless communications network and wireless user equipment includes receiving, using a primary Time Division Duplex (TDD) configuration, data on a primary component carrier in a first frequency band. Using a secondary TDD configuration, data on a secondary component carrier is received in a second frequency band different from the first frequency band. A Hybrid Automatic Repeat Request (HARQ) for data received on the secondary component carrier is transmitted using a supplemental TDD configuration. A transmission or retransmission on the secondary component carrier uses a supplemental TDD configuration as well. The supplemental TDD configuration is different from the secondary TDD configuration. Furthermore, an uplink supplemental configuration may be different from a downlink supplemental configuration.

    Abstract: Beamforming measurement techniques based on PSS/SSS are disclosed. An apparatus of a user equipment (UE) can include processing circuitry configured to decode a configuration message from a source serving cell, the configuration message indicating signal selection criteria for cell measurement reporting. A synchronization signal (SS) burst set associated with one or more transmission/reception points (TRPs) within a neighboring cell is decoded, the SS burst set including a plurality of SS blocks. A cell beamforming measurement signal associated with the neighboring cell is generated, based on signal measurements of the SS blocks and the signal selection criteria. A radio resource management (RRM) measurement report message is encoded for transmission to the serving cell, the measurement report message including the cell beamforming measurement signal. A handover command message for initiating a handover to the neighboring cell is decoded, the handover command based on the cell beamforming measurement signal.

  • Publication number: 20230087582
    Abstract: Systems and methods of reducing control plane latency in a 5G IAB network are described. SRs transmitted between nodes indicate that a control plane PDU is to be transmitted. The SRs use periodic resources or OCCs reserved for control plane signaling and are initiated by an RRC message or RACH from the UE. The SRs are initiated if the LCD field in the MAC sub header of the RRC message indicates the CCCH or the DCCH logical channel. If the PDU is available after the original resource, a resource is used that is provided via another grant, which is periodically provided or automatically initiated due to failure to transmit on the original grant. The SR or RRC message can also specify a delayed timeslot for the grant. For contention-based procedures the RACH preamble is randomly selected or selected from among a set of RACH preambles assigned for RRC procedures.

  • Patent number: 11445564
    Abstract: Techniques described herein may be used to enable User Equipment (UE) to switch between Radio Access Technologies (RATs) while transitioning from an inactive state to an active state. For example. a UE may connect to a base station via one type of RAT (e.g., Long-Term Evolution (LTE) RAT), enter an inactive state, and later, while transitioning from the inactive state to an active state, connect to another base station via another type of RAT (e.g., a New Radio (NR) or 5th Generation (5G) RAT). The UE may transition from one RAT to another RAT without increasing signaling between the UE and the network beyond minimal signaling involved in a transition of the UE from the inactive state to an active state. The network may further minimize signaling by determining and communicating minimized connection configuration information to the UE.
