Abstract: Embodiments of the present application provide an electrode piece, a battery cell and a battery, where the electrode piece includes a current collector, a first material layer, and an active material layer; the first material layer and the active material layer are provided on a surface of the current collector, and the first material layer and the active material layer extend along a length direction of the current collector and are alternately arranged in a width direction of the current collector; where the first material layer includes a first material, and the first material includes an amphiphilic polymer and a structural conductive polymer. The infiltration effect of the electrolyte can be improved, the aging time is shortened, and an injection amount of electrolyte is reduced.

Abstract: A method includes acquiring multiple pieces of first received signal quality information at a receiver, where the multiple pieces of first received signal quality information represent qualities of signals received at the receiver, generating first conditional sample statistical values based on the multiple pieces of first received signal quality information and phase shift arrays corresponding to the signals, determining the first phase shift array that meets a communication requirement according to the first conditional sample statistical values, where the first phase shift array includes the phase shift value for at least one reflective element of an IRS, and configuring the IRS based on the first phase shift array.

Abstract: In accordance to embodiments, a base station may transmit to a first user equipment (UE) a downlink control information (DCI) message for uplink (UL) scheduling of a second UE. The DCI message may indicate resources for sending a UL message by the second UE to the base station such that the first UE can at least partially decode the UL message based on the information in the DCI message. The base station may receive the UL message from the second UE. The base station may send a downlink (DL) message to the first UE. The UL message and the DL message may overlap at least partially in time and frequency. If the DL UE cannot successfully decode the UL message, the base station may send a helper message for the UL message to help the DL to decode the UL message.
