A wireless device receives parameters comprising a radio network temporary identifier (RNTI) associated with a multicast and broadcast service (MBS) session; a first scrambling identity associated with the MBS session; and a second scrambling identity associated with unicast transmissions. The wireless device receives, based on the RNTI, a group common downlink control information (DCI) scheduling a transport block (TB) of the MBS session. Based on the group common DCI being received based on the RNTI, the wireless device determines a scrambling identity for the TB being equal to the first scrambling identity, and receives the TB being scrambled with a scrambling sequence initialized by the determined scrambling identity and the RNTI.

A method of wireless communication includes selecting, by a user equipment (UE), a first codepoint from a codebook based on control information to be transmitted to a base station. The codebook is associated with non-coherent transmissions from the UE to the base station. The method further includes generating, based on the first codepoint and a scrambling sequence that is associated with the UE, a second codepoint representing the control information. The method further includes transmitting the second codepoint by the UE to the base station.

Examples described herein include systems and methods which include wireless devices and systems with examples of full duplex compensation with a self-interference noise calculator. The self-interference noise calculator may be coupled to antennas of a wireless device and configured to generate adjusted signals that compensate self-interference. The self-interference noise calculator may include a network of processing elements configured to combine transmission signals into sets of intermediate results. Each set of intermediate results may be summed in the self-interference noise calculator to generate a corresponding adjusted signal. The adjusted signal is received by a corresponding wireless receiver to compensate for the self-interference noise generated by a wireless transmitter transmitting on the same frequency band as the wireless receiver is receiving.

A system and method that scrambles the phase characteristic of a carrier signal are described. The scrambling of the phase characteristic of each carrier signal includes associating a value with each carrier signal and computing a phase shift for each carrier signal based on the value associated with that carrier signal. The value is determined independently of any input bit value carried by that carrier signal. The phase shift computed for each carrier signal is combined with the phase characteristic of that carrier signal so as to substantially scramble the phase characteristic of the carrier signals. Bits of an input signal are modulated onto the carrier signals having the substantially scrambled phase characteristic to produce a transmission signal with a reduced PAR.

This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e., indicate which downlink component carrier(s) is/are to be activated or deactivated. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated.

This application provides a physical broadcast channel sending/receiving method and an apparatus. In the method, after receiving two broadcast channel signals on two corresponding physical broadcast channels at two time-frequency resource locations, the terminal device determines that information other than an offset of a corresponding time-frequency resource location is the same in two pieces of broadcast information carried in the two broadcast channel signals, obtains a time offset difference between the foregoing two time-frequency resource locations, and generates a scrambling sequence based on the time offset difference; and the terminal device separately descrambles the two broadcast channel signals based on the scrambling sequence and a preset scrambling sequence, thereby implementing joint decoding on the two broadcast channel signals, to obtain one piece of broadcast information.

The present disclosure relates to a method for a terminal device to determine demodulation reference signal (DMRS), comprising: obtaining (211) a DMRS configuration and a corresponding signature assigned by a network side node; constructing (212) a DMRS according to the DMRS configuration; mapping (213) the DMRS to a physical channel assigned to the terminal device. The signature indicates a processing configuration for the physical channel. In the embodiments of the present disclosure, the signature, and DMRS configuration may be configured correspondingly, to obtain low-crosstalk DMRS signals for different terminal devices, thus, the number of the supported terminal devices may be improved.

A communication link initialization method includes that a master node sends a first information frame to a slave node. The first information frame includes first synchronization information. The slave node implements synchronization with the master node based on the first synchronization information. The slave node sends a second information frame to the master node. The second information frame includes second synchronization information. The master node implements synchronization with the slave node based on the second synchronization information. The master node sends a third information frame to the slave node. The third information frame is used to indicate a first training information frame. The slave node trains a link between the master node and the slave node based on the third information frame. The slave node sends a fourth information frame to the master node.
