Abstract: Techniques for scrambling sequence generation may provide scrambling for a reference signal, a control signal, or a data signal that is independent of a center frequency of a wireless system bandwidth. Generated scrambling sequences may allow for demodulation of signals in which a synchronization channel does not share a same center frequency as the wireless system bandwidth.

Abstract: Aspects for balancing power output on the plurality of antennas for the transmission of a transport block are disclosed. In accordance with the present disclosure, a transmitter may balance the power output on a plurality of transmit antennas in a multiple-input multiple-output (MIMO) system by having a precoded data block bypass a virtual antenna mapping of the overhead channels (e.g., control channels). Additionally or alternatively, the transmitter may balance the power output on the plurality of transmit antennas by applying an inverse mapping parameter during the precoding process to the transport block to generate a plurality of inverse mapped precoded data blocks. In some examples, the inverse mapping parameter may be an inverse of the mapping parameter. Thus, in accordance with the present disclosure, precoding a transport block may include selecting a precoding weight for each of the plurality of antennas from an unrestricted precoding weight set.
Abstract translation: 公开了用于平衡用于传输块的传输的多个天线上的功率输出的方面。 根据本公开，发射机可以通过使预编码数据块绕过架空信道的虚拟天线映射来平衡多输入多输出（MIMO）系统中的多个发射天线上的功率输出（例如， 控制通道）。 附加地或替代地，发射机可以通过在预编码处理期间向传输块应用反映射参数来平衡多个发射天线上的功率输出，以生成多个逆映射预编码数据块。 在一些示例中，反映射参数可以是映射参数的逆。 因此，根据本公开，传输块的预编码可以包括从无限制的预编码权重集合中选择多个天线中的每一个的预编码权重。

Abstract: Disclosed are techniques for enabling a user equipment (UE) operating in carrier aggregation mode to use different connected mode discontinuous reception (CDRX) configurations for different sets of component carriers associated with different sets of numerologies. For example, in Frequency 1 (FR1) plus Frequency 2 (FR2) carrier aggregation (i.e., one or more FR1 component carriers and one or more FR2 component carriers), a different CDRX can be configured for FR1 than for FR2. In inter-band carrier aggregation (i.e., one or more component carriers in one frequency band and one or more component carriers in another frequency band), CDRX can be configured per band. For mixed numerologies carrier aggregation (i.e., one or more component carriers with a first numerology and one or more component carriers with a different numerology), CDRX can be configured per cell group, where each cell group contains a single numerology or mixed numerologies.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may employ joint paging techniques. Multiple base stations may coordinate to determine joint paging parameters for a joint paging area. Each base station in the joint paging area may use the same paging parameters to generate the same joint paging message. The base stations in the joint paging area may communicate over backhaul links, such as an Xn interface. A user equipment (UE) in the joint paging area may be provided the joint paging parameters and monitor for paging messages based on the joint paging configuration. In some cases, the UE may be provided the joint paging parameters in a resource release message. Additionally, or alternatively, a base station of the joint paging area may broadcast the joint paging parameters.

Abstract: Techniques are described herein for signaling procedures that use a hierarchical mobility, which may be applied when a user equipment (UE) is operating in a radio resource control (RRC) inactive state or the RRC idle state. A wireless communication system may be configured with a plurality of areas in which one or more networks are established for communicating certain types of signals. Examples of the areas associated with networks may include a tracking area (TA), a radio access network area code (RAN-AC), a radio access network based notification area (RNA). A synchronization signal or a paging signal may be transmitted using a first set of communication resources in a first area, while the synchronization signal or the paging signal may be transmitted using a second set of communication resources in a second area different than the first set of communication resources.
