摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink data communication. The UE may determine a processing time for the downlink data communication based at least in part on at least one of: whether the downlink data communication was scheduled via preconfigured scheduling or via a downlink grant received in a downlink control channel, or whether the downlink data communication is an initial transmission or a retransmission. The UE may transmit acknowledgement or negative acknowledgement (ACK/NACK) feedback, corresponding to the downlink data communication, using a timing indicated by the processing time. Numerous other aspects are provided.

摘要： An encoder outputs a first bit sequence having N bits. A mapper generates a first complex signal s1 and a second complex signal s2 with use of bit sequence having X+Y bits included in an input second bit sequence, where X indicates the number of bits used to generate the first complex signal s1, and Y indicates the number of bits used to generate the second complex signal s2. A bit length adjuster is provided after the encoder, and performs bit length adjustment on the first bit sequence such that the second bit sequence has a bit length that is a multiple of X+Y, and outputs the first bit sequence after the bit length adjustment as the second bit sequence. As a result, a problem between a codeword length of a block code and the number of bits necessary to perform mapping by a set of modulation schemes is solved.

摘要： Aspects of the present disclosure generally relate to wireless communication. For example, aspects of the present disclosure provide techniques for determining one or more modulation orders to be used for the communication of control channels and/or data channels. An exemplary method, performed by a UE, may include receiving downlink control information (DCI) that allocates resources for a communication, the DCI may include a first field that indicates a transport block size (TBS) of the communication and a second field, different from the first field, that indicates a modulation order of the communication, wherein the communication includes a transmission or a reception, and processing the communication according to the indicated modulation order. Numerous other aspects are provided.

摘要： Disclosed is an access point (AP) for a network that includes security features for interacting with devices on the network. The other devices on the network may be other APs, client devices, or a backend configuration server. The access point includes a private key that is used to verify signals to and from (the private key may be different for different functions). In the case of other APs, the private key is used to verify control signals sent between the APs to identify and prevent a hijacked AP from taking control of the network by sending false control signals. In the case of a client device, the client device may use the subject AP's private key to identify that the subject AP is a trusted member of the network that may receive data. In the case of the backend server, the subject AP may verify configuration updates via use of the private key to prevent loading of malicious firmware.

摘要： A base station according to an embodiment is a base station configured to perform transmission to a user terminal by use of an unlicensed band. The base station comprises: a controller configured to start the transmission from a boundary of a subframe, but also to start the data transmission from a second-half slot out of a first-half slot and the second-half slot which configure a subframe. The controller is configured to transmit downlink control information in the second-half slot to start the transmission from the second-half slot. The controller is configured to change a modulation scheme to be applied to the transmission, depending on a start timing of the transmission, while fixing a transport block size applied to the subframe. The downlink control information is a PDCCH or an EPDCCH.
