    摘要： A method and apparatus are provided for performing information-theoretically secure cryptography using joint randomness not shared by others. Two valid communicating entities independently generate samples of a shared source that is not available to an illegitimate entity. The shared source may be a satellite signal, and each legitimate entity may generate uniformly distributed samples from a binary phase-shift keying signal received on an independent channel. Alternatively, the shared source may be a channel between the two legitimate entities, such that each legitimate entity generates samples of unknown distribution based on the channel impulse response of the channel. One legitimate entity generates an encryption key, a quantization error, and a syndrome from its samples. The quantization error and the syndrome are reported to the other legitimate entity. The other legitimate entity generates a matching encryption key using its samples, the quantization error, and the syndrome.

    摘要： A method and apparatus for use in a wireless transmit receive unit (WTRU) for receiving system information. A WTRU receives a broadcast signal from a gNB, wherein the broadcast signal includes system information. The WTRU determines configuration information associated with the received system information and the WTRU transmits a signal to the gNB using the determined configuration information associated with the received system information. The configuration information includes an indication regarding whether the WTRU is able to include any one or a combination of a request signal or a feedback signal in the signal transmitted to the gNB. The transmitted signal to the gNB may include a preamble that indicates system information block (SIB) request information. The transmitted signal to the gNB may include a control field that indicates additional SIB request information. The transmitted signal may provide feedback for the received system information. The WTRU then receives system information from the gNB in response to the transmitted signal. The received system information in response to the transmitted signal is one or more SIBs.

    摘要： A method, implemented in a first WTRU comprises a step of transmitting, to a network node, a first message comprising first information indicating a scheduling request for sidelink transmission resources. The method comprises a step of receiving, from the network node, a second message comprising second information indicating the sidelink transmission resources based on the first message. The method comprises a step of transmitting, to a second WTRU, sidelink data, based on the received sidelink transmission resources. The method comprises a step of receiving, from the network node, a third message comprising third information indicating sidelink retransmission resources for the sidelink data transmission; and a step of transmitting, to the second WTRU, the sidelink data based on the received retransmission resources.

    摘要： Systems and methods for dynamic white space management are described. First, local handling of channel queries, in which a channel query by a white space device (WSD) is handled by a local dynamic spectrum management(DSM) server, if the DSM server has all the information necessary for providing a response to the channel query. Second, a search extension, in which a WSDB passes part of a search for available channels to a local DSM server. Third, assisting of an available channel calculation, in which a DSM server provides spectrum sensing information to WSDBs to improve the available channel calculation within the WSDBs. And fourth, dynamic bandwidth management to meet the coexistence requirements. In addition, the content of the messages and procedures that enable the above value-adding functions and interactions with the WSDB systems are described.
