    Abstract: The present invention provides a use of canagliflozin in preparation of an antitumor drug, especially in preparation of a drug for treating solid tumors. It has been proven through researches that canagliflozin has a significant down-regulation effect on immune checkpoint protein PD-L1 in various tumor cells and can effectively enhance the killing effect of T cells on tumor cells in a co-incubation model of T cells and tumor cells, thereby broadening a clinical application scope of the chemical drug canagliflozin in tumor immunotherapy. The present invention provides a new medical use of canagliflozin, and also provides new approaches and potential targets for the development of small molecular drugs based on PD-L1.

  • Publication number: 20220022068
    Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for configuring sidelink beam failure detection reference signals for determining beam failures on a sidelink between a first sidelink user equipment (UE) and a second sidelink UE. The first UE may determine a first set of sidelink beam failure detection reference signals to transmit to the second UE and a second set of sidelink beam failure detection reference signals to receive from the second UE. The first UE may transmit the first set to the second UE using a set of sidelink transmit beams. The first UE may further monitor for the determined second set using a set of sidelink receive beams. Based on the first and second set of sidelink beam failure detection reference signals, the first and second UE may communicate over the sidelink.

  • Publication number: 20220006688
    Abstract: A method of wireless communication by a first sidelink user equipment (UE) transmits a sidelink (SL) beam failure recovery (BFR) message to a communications node, indicating a new candidate beam and an identifier (ID) of a second sidelink UE. The method also receives an acknowledgment of the SL BFR message. A communications node receives a sidelink beam failure recovery message from a first sidelink user equipment, indicating a new candidate beam and an ID of a second sidelink UE. The method also transmits information identifying the new candidate beam and the ID to the second sidelink UE. Another method by a first sidelink user equipment receives a sidelink beam failure recovery message from a base station, indicating a new candidate beam and an ID of a second sidelink UE. The method changes a beam used to communicate with the second sidelink UE in response to receiving the BFR message.

  • Publication number: 20220007448
    Abstract: A method of wireless communication, by a first sidelink user equipment (UE), includes periodically receiving a set of sidelink beam failure detection reference signals (RSs) from a second sidelink UE. The method includes incrementing a beam failure detection (BFD) counter in response to one or more reference signals of the set of sidelink beam failure detection RSs having a received signal strength below a threshold. The first sidelink UE starts a beam failure detection timer in response to the reference signal(s) of the set of sidelink beam failure detection reference signals having the received signal strength below the threshold. Another method by a sidelink UE may periodically transmit a set of sidelink BFD RSs to another sidelink UE. The set of sidelink BFD RSs comprise one or more sidelink receive RSs. The sidelink UE configures the other sidelink UE with the sidelink receive BFD RSs.

  • Publication number: 20210321343
    Abstract: Methods, systems, and devices for wireless communications are described. Sidelink UEs may be configured with a synchronization reference signal that may be used by the UEs to synchronize time and frequency resources. A first and second UE may perform a beam sweeping procedure to identify transmit and receive beams to use for communications between the UEs. A synchronization reference signal procedure may be initiated and the first UE may receive a sidelink synchronization reference signal from the second UE using the established receive beam. The UEs may align time and frequency resources for communications between the UEs and the UEs may communicate via the sidelink channel based on the time synchronization, frequency synchronization, or both, determined using the sidelink synchronization signal. In some cases, a sidelink UE may receive multiple synchronization reference signals from multiple sidelink UEs simultaneously, where each synchronization reference signal may include a UE identifier.

  • Publication number: 20210307049
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for using different configurations for downlink or uplink transmissions associated with different transmission configuration indication (TCI) states (e.g., transmitted on different beams). In one example, a base station may use different configurations for downlink transmissions to a user equipment (UE), and the base station may indicate the different configurations to the UE. For instance, the base station may transmit downlink control information (DCI) indicating a baseline configuration and other configurations as a delta of the baseline configuration. In another example, a base station may dynamically indicate a timing advance to a UE (e.g., in DCI or flow control feedback) for an uplink transmission from the UE associated with a TCI state, and the UE may use the dynamically indicated timing advance for uplink transmissions associated with the TCI state.
