    Abstract: A method of interference cancellation is proposed. A serving base station transmits a first configuration information to a UE, the first configuration information is related to a desired signal of a data transmission from a serving cell to the UE. The serving base station determines a second configuration information related to an interference signal of a data transmission from a neighboring cell to the UE. The second configuration information comprises a resource allocation type and a basic resource allocation unit of the interference signal. The serving base station transmits the second configuration information to the UE such that the UE can cancel the data transmission from the neighboring cell.

    Abstract: A method for a receiver to cancel or suppress co-channel interference with network assistance is provided. The method comprises deriving a first set of parameters related to interfering signals in a mobile communication network; receiving a second set of parameters related to the interfering signals from the network; and cancelling the contribution of interfering signals from the received signal based on the combination of the first set and second set of parameters. In one embodiment, the interfering signals comprise intra-cell interfering signals and/or inter-cell interfering signals. While inter-cell interference comes from neighboring cells, intra-cell interference comes from MU-MIMO transmission to other users in the same serving cell as the victim UE. In one example, the serving base station not only signals information to the victim UE for inter-cell interference, but also for intra-cell interference due to MU-MIMO transmission.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE discovers a relay wireless device for local communications on an unlicensed carrier. The UE communicates, after a listen-before-talk (LBT) procedure is successful on the unlicensed carrier, data with the relay wireless device on the unlicensed carrier through the local communications for further communicating the data with a base station.

    Abstract: A wireless device receives a first PDCCH from a base station. The first PDCCH indicates a resource allocation of a first PDSCH transmitted on a first time-frequency resource. The wireless device decodes data carried in the first PDSCH according to the first PDCCH. The wireless device obtains a resource allocation of a second PDSCH based on a mapping rule. The mapping rule maps resources of the first PDSCH to resources of the second PDSCH. The wireless device generates encoded bits for the second PDSCH. The encoded bits are based on the decoded data carried in the first PDSCH and the resource allocation of the second PDSCH. The wireless device generates reference signals associated with the second PDSCH. The wireless device transmits the encoded bits to a user equipment (UE). The encoded bits are transmitted on the resources of the second PDSCH on the second time-frequency resource.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a first wireless device of a group of M wireless devices. The first wireless device receives a first time domain signal from a user equipment (UE) on a first frequency band through each receiving antenna. This first time domain signal occupies a first transmission time interval (TTI1) and includes K first OFDM symbols corresponding to a first subcarrier spacing. Each first OFDM symbol represents a set of N1 modulation symbols on N1 subcarriers using the first subcarrier spacing. The first wireless device generates a second time domain signal that occupies a second transmission time interval (TTI2) and corresponds to the first time domain signal. The first wireless device transmits each second time domain signal to a base station on a second frequency band through a transmitting antenna, respectively.

    Abstract: A group of M wireless devices receive a first time domain signal on a first frequency band through each receiving antenna of each wireless device. The first time domain signal includes K first OFDM symbols corresponding to a first subcarrier spacing. Each first OFDM symbol represents a set of N1 modulation symbols on N1 subcarriers using the first subcarrier spacing. Each wireless device generates a second time domain signal occupying a second interval and corresponding to the first time domain signal. A jth second OFDM symbol of K second OFDM symbols represents a set of N2 modulation symbols on N2 subcarriers using the second subcarrier spacing, derived from the set of N1 modulation symbols represented by a jth first OFDM symbol of the K first OFDM symbols. Each wireless device transmits each second time domain signal on the second frequency band through a transmitting antenna of the each wireless device.

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE monitors a respective down link control channel (DCCH) from each of a plurality of transmission and reception points (TRPs). The UE receives, from a first TRP of the plurality of TRPs, a first trigger for reporting N1 channel state information (CSI) reports within a time duration, N1 being an integer greater than 0. The UE commits to update the N1 CSI reports. The UE determines that P processing units are remaining available for calculation of CSI reports while the UE is calculating the N1 CSI reports. P is a number greater than or equal to zero. Each of the P processing units indicates a predetermined amount of computing power of the UE.
