Abstract: Embodiments of this application provide a downlink control information transmission method in which after receiving one piece of downlink control information (DCI), the terminal device learns whether blind detection of DCI needs to be continued. The method includes: A terminal device receives first DCI, where the first DCI includes first indication information, and the first indication information is used to indicate a first antenna port. The terminal device determines, based on the first antenna port and antenna port configuration information, whether second DCI exists. The configuration information may include an index of a CDM group to which each of a plurality of antenna ports belongs and a maximum quantity of CDM groups that is supported by the terminal device. Alternatively the configuration information may include one or more antenna port groups, and each of the one or more antenna port groups includes one or more antenna ports.

Abstract: Methods, systems, and apparatuses to fuse a first dataset with a second dataset, and determine head pose estimation(s) based on the fused first dataset and second dataset. The first dataset may be associated with sensor data generated by a set of sensors of a first device, while the second dataset may be associated with sensor data generated by a first sensor of an apparatus. For example, an apparatus may obtain the first dataset and the second dataset. Additionally, the apparatus may generate a fused dataset based on the first dataset and the second dataset, and determine a head pose estimation of a head of the user based on the fused dataset. Further, the apparatus may output the third head pose estimation.

Abstract: A method for configuring a service and a method and apparatus for rate matching in a TD-SCDMA system, this method for configuring the service includes: taking that a check bit puncturing ratio should be more than 7i+a or less than 7i?a as a newly added constraint condition, and the check bit puncturing ratios of each configured service being outside a range of [7i+a, 7i?a], the method for rate matching includes: when puncturing each path of check bits of the current data block, if a difference between a position Pk of kth reserved check bit calculated according to a method defined by the service and a previously determined position NPk?1 of k?1th reserved check bit is a positive integral multiple of 7, determining a position NPk of kth reserved check bit as Pk plus 1 or Pk minus 1, and Pk plus 1 and Pk minus 1 requiring carrying out alternately.
