摘要： Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may randomly select a private key of the UE. The UE may receive, from the gNB, control signaling that includes a public key of the gNB. The UE may generate a shuffling key based at least partly on a public function of the private key of the UE and the public key of the gNB. The UE may determine a random sequence of bits based on a random number generation operation with the shuffling key as a seed. The UE may determine, based on the random sequence of bits, a shuffling array for shuffling of coded bits. The UE may generate the coded bits, and may shuffle the coded bits in accordance with the shuffling array.

摘要： A 3GPP LTE protocol enhancement realizes the full benefit of discontinuous reception (DRX) in Long Term Evolution networks by coordinating and aligning DRX operations for conserving power and timing overhead. A dual connectivity enabled User Equipment (UE) comprising a processor and transceiver is configured to align DRX configuration between counterpart Evolved Node Bs (eNB)s, wherein counterpart eNBs are a Master eNB (MeNB) and a Secondary eNB (SeNB) simultaneously connected to the UE, communicate system frame timing and system frame number (SFN) information between the counterpart eNBs, align DRX start offset (drxStartOffset) values for the counterpart eNBs according to the communicated system frame timing and SFN information to compensate for offsets in system frame timing, and allow the start of a DRX ON duration at specific frame or sub-frame times determined by the drxStartOffset values, after the expiration of a DRX inactivity timer.

摘要： A method for providing a dual-channel beacon signal to protect a low-power device in a wireless network is provided. The method includes generating a beacon message in a first logical channel and generating a detection signal in a second logical channel. The first logical channel and the second logical channel are mapped into a first physical channel and a second physical channel. The second physical channel is orthogonal to the first physical channel. The dual-channel beacon signal is transmitted by simultaneously transmitting the beacon message and the detection signal in the first physical channel and the second physical channel.

摘要： A method and apparatus for joint unicast using multi-user superposition coding in a wireless relay system are provided. A BS superposition-encodes first and second data messages directed to first and second MSs, respectively, scheduled at a current scheduling instant. The first and second data messages carry first and second information bit streams for the first and second MSs, respectively. The first MS has a relatively good direct link to the BS, and the second MS has a relatively bad direct link to the BS. The superposition-coded data is transmitted to the first MS and an RS connected between the BS and the first and second MSs. The RS receives the superposition-coded data from the BS, extracts the second information bit stream by decoding the superposition-coded data, and transmits a third data message carrying the second information bit stream to the first and second MSs.

摘要： Provided is an apparatus and method for efficiently transmitting packets to MSs in a BWA system using RSs. A BS uses an ESH to combines packets, which are to be transmitted through RSs to MSs, into a larger packet prior to transmission. Alternatively, the BS transmits packets, which are to be transmitted to MSs, to an RS without discrimination therebetween, and the RS determines whether the packets are to be transmitted to the MSs, prior to transmission.
