Abstract: Embodiments of the present disclosure disclose a precoding configuration method, device, and system. The precoding configuration method includes: generating precoding configuration information, where the precoding configuration information is used to configure a width of a frequency band for same precoding; and sending the precoding configuration information. The embodiments of the present disclosure further provide a transmit end device, a receive end device, and the precoding configuration system. In the precoding configuration method provided in the embodiments of the present disclosure, the precoding configuration information is generated and sent, so that a receive end can determine, based on the precoding configuration information, the width of the frequency band for same precoding. In the prior art, the width of the frequency band for same precoding is determined based on only system bandwidth, while the width of the frequency band for same precoding can be flexibly determined in the technical solutions provided in the embodiments of the present disclosure, so that requirements of a wireless communications system can be met in diversified scenarios, and system performance can be effectively optimized in different scenarios.

Abstract: It is possible to reduce the processing intensity of blind detection by configuring user equipments (UEs) to search for fewer than all possible DCI formats defined for a physical downlink control channel (PDCCH), as this reduces the number of searches performed by the corresponding UE during blind detection. The UE may select the subset of DCI formats to search for during blind detection based on various criteria, such as an air interface configuration assigned to the UE, a UE group to which the UE belongs, a transmission mode used by the UE, a re-transmission scheme assigned to the UE, a characteristic (e.g., size, location) of the UE's search space, or a combination thereof.

Abstract: The present disclosure provide a data transmission method, including: receiving, by a central processing node, downlink user data from a first gateway GW; sending, by the central processing node, the downlink user data to a corresponding base station; and when it is determined that an interface between the central processing node and the first GW is congested, sending, by the central processing node, a first bearer switching request message to the first GW, where the first bearer switching request message is used to instruct the first GW to bypass the central processing node when transmitting data. In the embodiments of the present invention, when determining that an interface between a central processing node and a first GW is congested, the central processing node sends a first bearer switching request message to the first GW, so that the first GW transmits downlink user data with the central processing node bypassed.

Abstract: Signal processing complexity in fifth generation (5G) networks can be reduced by communicating wireless signals over self-contained partitions of a carrier such that the wireless transmission communicated over each self-contained partition of the carrier includes all physical control channel signaling required to decode data carried in a physical data channel of the partition. The control signaling may include resource assignment within the partition, modulation and coding scheme indication, reference signal configuration and retransmission information. In some embodiments, an anchor partition of a carrier is used to communicate initial access information for self-contained partitions of the carrier. The initial access information may include center-frequencies, bandwidths, and/or air interface configurations of the self-contained partitions. The anchor partition may also carry load indications associated with the self-contained partitions.
