  • Publication number: 20220151012
    Abstract: Some aspects of the present disclosure introduce a new downlink (DL) bandwidth part (BWP) and a new uplink (UL) BWP for communication in the RRC_INACTIVE state. In addition, aspects of the disclosure also provide for configuring generic parameters of the BWP, which include, but not limited to, frequency location, bandwidth, subcarrier spacing (SCS), and cyclic prefix (CP). Some aspects of the present disclosure may support a reinterpretation of generic parameters of a BWP, for example which may be configured for the RRC_CONNECTED state, to be used in the RRC_INACTIVE state. Some aspects of the present disclosure are directed to implicit DL BWP switching in the RRC_INACTIVE state where no BWP identifier (ID) indication is needed as part of the switching mechanism.

  • Patent number: 11284429
    Abstract: Control signaling mechanisms are provided to support data transmissions to or from a user equipment (UE) in an inactive state. In some embodiments, a UE in an inactive state receives DCI including: a cyclic redundancy check (CRC) scrambled by a radio network temporary identifier (RNTI) that is specific to a group of UEs, the group of UEs including the UE; and a resource assignment for a data transmission to the UE. The data transmission is then received on a physical shared channel. In further embodiments, a UE in an inactive state receives DCI including: a CRC scrambled by a paging RNTI; and a resource assignment for a paging message to the UE. A data transmission is received by the UE in the paging message or in a further transmission that is scheduled by the paging message.

    Abstract: Some embodiments of the present disclosure provide control signaling mechanisms to support data transmission by a user equipment (UE) that is in the RRC_INACTIVE state and, more generally, in any inactive state. Beyond simply supporting data transmission by a user equipment that is in the RRC_INACTIVE state, aspects of the present application provide mechanisms for configuring the UE for preamble transmission or sounding reference signal (SRS) transmission and for toggling between such transmissions. Aspects of the present application relate to mechanisms for enabling Timing Advance estimation, which mechanisms are not burdened with high overhead and which allow the UE to remain in the RRC_INACTIVE state.

  • Publication number: 20220029768
    Abstract: Systems and methods for transmitting uplink control information, for example ACK/NACK, while in RRC_inactive state, are provided. Uplink control information is transmitted while in RRC_INACTIVE state by transmitting a sequence from a set of possible sequences to convey the uplink control information, the transmitted sequence associated with a value of the uplink control information. The sequence is asynchronously transmitted. Signalling may be used to configure a transmission resource within which to transmit the sequence, wherein the transmission resource has a time duration that is longer than a time duration to transmit the sequence. This has the effect of introducing a gap following sequence transmission that can ensure the sequence transmission does not interfere with a data transmission.

  • Publication number: 20210367818
    Abstract: The middle subcarrier of the baseband OFDM signal of each numerology may need to be shifted appropriately with respect to other numerologies to comply with a nested grid. These shifts can be signalled to the UE with an associated overhead. Methods and systems are provided to reduce overhead for OFDM communication. Reduced overhead can translate into increased bandwidth for the system, and/or reduced power/battery consumption in the UE. A transmitter generates an OFDM signal associated with a first subcarrier spacing of a first numerology (?), a middle subcarrier frequency of a set of usable resource blocks (RBs) of the first numerology being offset from a carrier frequency by a first offset having a value (k0,x?) in units of subcarriers, the value of the first offset being defined by a specific formula. The transmitter transmits the OFDM signal according to the first subcarrier spacing and the first offset.

  • Patent number: 11133969
    Abstract: Aspects of the present application use a linear transformation of a sparse mapped single carrier transmission at a transmitter, for which a comparable inverse transform of the linear transform applied at the transmitter can be applied at the receiver. The linear transform reduces the sparsity of sparse mapped symbols. The use of the linear transform to reduce the sparsity enables peak-to-average power ratio (PAPR) and/or cubic metric to be reduced as compared to if the linear transform is not used. The linear transforms may be implemented in a block-wise manner, element-wise manner or combination thereof.

  • Patent number: 11109378
    Abstract: A sidelink (SL) configuration for SL communications directly between a communication terminal and another communication terminal is separate from a communication network link configuration for communications with network equipment in some embodiments. An SL configuration, which could be an SL reconfiguration or an SL preconfiguration for use by the communication terminal after the terminal transitions from in coverage to out of coverage, could be transmitted through network/terminal signaling, and detailed examples of such signaling are disclosed herein. An SL configuration could be or include an SL bandwidth part (BWP) configuration and an SL communication resource configuration, such as one or more resource pools, within the SL BWP.

  • Patent number: 11089582
    Abstract: Aspects of the present disclosure provide methods, devices and systems that limit a number of DCI payload sizes in order to limit the complexity of processing needed to perform blind decoding of the DCI payload. Various embodiments are provided that limit the number of DCI payload sizes. A base station determines the payload sizes to be used for a given time slot and once generated, transmits the DCI to one or more UEs. The UE is responsible for receiving the DCI and performing blind decoding to decode the information intended for the UE. In some embodiments, limiting the number of payload sizes may result in some DCI content that is smaller than the allotted DCI payload size being padded with zero bits to fill the allotted DCI payload size.
