  • Patent number: 11832267
    Abstract: Technology for a low mobility user equipment (UE) operable to perform uplink (UL) transmissions using configured grant (CG) physical uplink shared channel (PUSCH) resources is disclosed. The UE can decode a CG PUSCH resource configuration from an eNodeB while the low mobility UE is in a radio resource control (RRC) connected state. The CG PUSCH resource configuration can indicate CG PUSCH resources for the low mobility UE after the low mobility UE transitions from the RRC connected state to an RRC idle state. The UE can transition from the RRC connected state to the RRC idle state. The UE can encode data packets for transmission over a PUSCH to the eNodeB using the CG PUSCH resources while the low mobility UE is in the RRC idle state.

  • Patent number: 11671844
    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may transmit a message to a base station (e.g., a NodeB, an eNodeB (eNB), a next-generation NodeB or a giga-NodeB (either of which may be referred to as a gNB)) in wireless communications with the UE. The message may include a UE capability to append a preamble waveform to an uplink transmission to the base station. In some examples, a preamble waveform may include a Wi-Fi preamble or a new radio unlicensed (NR-U) preamble. Based on the UE capability, the base station may determine and transmit a preamble configuration to the UE, which the UE may use to generate and append a preamble waveform to another message for an uplink transmission to the base station.
