摘要： This disclosure describes methods for periodic resource allocation between a Tx-UE and an Rx-UE. For periodic resource reservation of a Tx UE, it is possible to have contiguous resource collisions with another Tx-UE's periodic resource reservation. This invention provides methods to overcome this collision problem based on reception status of Rx-UE's SL HARQ feedback.

摘要： A method of wireless communication of a UE is provided. The UE determines K1 information bits carrying one or more CSI reports, the one or more reports including a first CSI report, K1 being an integer greater than 0. The UE selects K2 information bits from the K1 information bits, the K2 information bits excluding a part of information bits of the first CSI report, K2 being an integer greater than 0 and smaller than K1. The UE determines that the K2 information bits are in a first predetermined relationship with a threshold. The UE transmits E2 encoded bits derived from the K2 information bits in a physical up-link channel to a base station, E2 being an integer greater than 0.

摘要： Various solutions with respect to codebook-based uplink transmission in wireless communications are described. A user equipment (UE) receives a signal indicating codebook subset restriction (CBSR) from a network node of a wireless network. The UE selects one or more codewords or a codebook from a plurality of different codebooks within a master codebook responsive to receiving the signal. The UE then processes data using the selected codebook and performs an uplink (UL) multiple-input-and-multiple-output (MIMO) transmission of the processed data to the network node.

摘要： A method of modulating and demodulating superposed signals for MUST (MultiUser Superposition Transmission) scheme is proposed. A transmitter takes bit sequences intended for multiple receivers under MUST scheme to go through a "bit sequence to constellation points" mapper before entering the modulators to satisfy the Gray coding rule and to achieve high demodulation performance for the receivers. In a first method, each bit sequence is assigned for each constellation point on the constellation map to satisfy one or more conditions under different power split factors. In a second method, the constellation map is divided into sub-regions according to the clustering of the constellation points for bit sequence assignment. A near-UE may use an ML (Maximum Likelihood) receiver for demodulation and decoding the superposed signal. A far-UE may use an ML receiver or an MMSE (Minimum Mean Square Error) receiver for demodulation and decoding the superposed signal.
摘要翻译：提出了一种用于MUST（MultiUser叠加传输）方案调制和解调叠加信号的方法。发射机采用MUST方案下的多个接收机的比特序列，以便在进入调制器之前通过“位序列到星座点”映射器，以满足格雷编码规则并实现接收机的高解调性能。在第一种方法中，为星座图上的每个星座点分配每个比特序列，以满足不同功率分割因子下的一个或多个条件。在第二种方法中，星座图根据用于比特序列分配的星座点的聚类被划分成子区域。近UE可以使用ML（最大似然）接收机来对叠加信号进行解调和解码。远UE可以使用ML接收机或MMSE（最小均方误差）接收机来对叠加信号进行解调和解码。

摘要： A method of performing downlink multiuser superposition transmission (MUST) when different precoders are applied to superposed signals is proposed. For demodulation reference signal (DM-RS) transmission mode, the near-user can estimate the far-user's channel by means of separate DM-RS symbols. For common reference signal (CRS) transmission mode, the near-user can blindly detect code far-user's precoder that is not signaled to the near-user. As a result, even the downlink control information (DCI) format is designed for the situation using the same precoder for superposed signals, the MUST scheme works and the near-user receiver can separate the superposed signal for the far-user.

摘要： When the codeword level interference cancellation (CW-IC) is used at the receiver in conjunction with the superposition coding scheme at the transmitter, it is helpful if the soft buffer at the receiver is reserved not only for the desired transport blocks (TBs) but also for the interfering TBs handled by the CW-IC. In so doing, the soft channel bits of interfering TBs at multiple (re) transmissions can be combined to enhance the success rate of data decoding. A soft buffer partition method for the soft channel bits of the desired and interfering TBs in the superposition coding scheme is proposed. The proposed method has a full flexibility in adjusting the soft buffer sizes for the desired and interfering TBs.

摘要： Methods for rate matching with soft buffer size setting at the transmitter and soft channel bits storage at the receiver for superposition coding are proposed. In the superposition coding scheme, a transport block intended to one UE needs to be decoded by another UE's receiver. However, the soft buffer sizes per code block of the two receivers may not be the same since the size depends on the UE category. The base station can signal the soft buffer size used at the transmitter for rate matching to the UEs for superposition decoding. A UE stores information bits associated with an interfering signal in its soft buffers in accordance with the soft buffer size used at the transmitter for rate matching. As a result, the UE can decode and subtract the interfering signal from the desired signal for superposition coding.
摘要翻译：提出了在发送器处的软缓冲器大小设置的速率匹配方法和用于叠加编码的接收机处的软信道比特存储的方法。在叠加编码方案中，用于一个UE的传输块需要被另一个UE的接收机解码。然而，两个接收机的每个码块的软缓冲器大小可能不一样，因为这个大小取决于UE类别。基站可以向UE发送用于速率匹配的发送机使用的软缓冲区大小，以进行叠加解码。 UE根据用于速率匹配的发送器使用的软缓冲器大小，将与干扰信号相关联的信息位存储在其软缓冲器中。结果，UE可以从用于叠加编码的期望信号中解码和减去干扰信号。

摘要： A method of interference cancellation is proposed. A UE obtains configuration information of a data transmission from a neighboring cell via an interference channel in a mobile communication network. The UE receives radio signals on a set of data resource elements as determined based on the obtained configuration information. The UE then estimates the interference channel corresponding to the data transmission from the neighboring cell based on the received radio signals on the set of data resource elements. Finally, the UE cancels the data transmission from the neighboring cell based on the estimated interference channel.
