Abstract: The present invention discloses a method and an apparatus for transmitting and obtaining scheduling information. The method for transmitting scheduling information includes determining UEs performing direct communication and scheduling information required for data transmission for the UEs performing the direct communication. A base station transmits invariable or slowly varying control information in the scheduling information to each of the UEs performing the direct communication statically or semi-statically. If the scheduling information further includes quickly varying control information. A UE serving as a sender in the UEs performing the direct communication transmits the quickly varying control information in the scheduling information dynamically or semi-dynamically to a UE serving as a receiver in the UEs performing the direct communication.

Abstract: The present disclosure relates to information transmission methods and communications devices. In one example method, a first communications device receives control information sent by a second communications device, where the control information is used to schedule a plurality of transport blocks (TBs). The first communications device determines a first value, where the first value is associated with one or more of a frequency hopping configuration parameter, a redundancy version (RV) change parameter, an interleaving gap parameter, and a quantity of transport blocks. The first communications device determines a first start time unit during transmission of a first TB, where the first TB is at least one of the plurality of TBs scheduled by the control information, and an index of the first start time unit is an integer multiple of the first value. The first communications device transmits the first TB based on the determined first start time unit.

Abstract: This application relates to the field of communication technologies, and provides a reference signal resource determining method and an apparatus. In a multi-point transmission mode, uplink sending occurs between reference signals from different transmission points in a CSI measurement process; consequently, phases are discontinuous on the reference signals received by a terminal device from the different transmission points. First, configuration information of a reference signal resource set is obtained to determine K reference signal resources, where K is a positive integer, and slots in which at least two of the K reference signal resources are located are different slots, or there is an uplink symbol in a first interval of at least two of the K reference signal resources.

Abstract: A control information communication method, a base station, and user equipment are provided. A determination is made whether downlink control information (DCI) is used for multicast transmission or for paging. When the DCI is determined to be used for multicast transmission, the DCI is scrambled by using a single cell radio network temporary identifier (SC-RNTI). The DCI includes indication information and scheduling information, the indication information indicating whether a multicast control channel is updated. When the DCI is determined to be used for paging, the DCI is scrambled by using a paging radio network temporary identifier (P-RNTI). The scrambled DCI can be sent to user equipment by using a first downlink control information format.
