Embodiment 1

[0055] In this embodiment, a method for sending control signaling is provided, figure 1 is a flowchart of a method for sending control signaling according to an embodiment of the present invention, such as figure 1 As shown, the process includes the following steps:

[0056] Step S102, determining second information according to the first information; wherein, the second information includes at least one of the following: the number of bits N used to notify the first transmission parameter in the first control signaling, the number of bits N used in the first control signaling, the first The corresponding mapping table between the index value referred to by the transmission parameter and the value of the first transmission parameter, the type of the first transmission parameter notified in the predetermined indication field in the first control signaling, the first transmission parameter notified in the first control signaling Bit position information used by a transmission p...

Embodiment 2

[0110] In this embodiment, according to the relationship between the physical layer dynamic control signaling and the transmission interval of the first signal and the predetermined threshold, at least one of the following information is determined: the transmission indicated by the specific indication field of the physical layer dynamic control signaling Parameter type, indicating whether the physical layer dynamic control signaling includes indication information indicating a specific transmission parameter type.

[0111] Further when the relationship is relationship one, the specific indication field of the physical layer dynamic control signaling is used to indicate the first type of transmission parameter;

[0112] When the relationship is relationship two, the specific indication field of the physical layer dynamic control signaling is used to indicate the second type of transmission parameter;

[0113] Further, when the relationship is relationship one, the physical lay...

Embodiment 3

[0121] In the above optional embodiment 1 and optional embodiment 2, the number of candidate parameter values ​​included in the value set of the first transmission parameter will change according to the first relationship, for example, when the interval between DCI and PDSCH is less than K When , the value set of the first transmission parameter includes X1 values, and when the value between DCI and PDSCH is greater than K, the value set of the first transmission parameter includes X2 values. Or when the interval between DCI and PDSCH is less than K, the corresponding mapping table between the index value referred to by the index value of the first transmission parameter in the DCI and the first transmission value is Table 1 (for example, as shown in Table 3) shown), when the distance between DCI and PDSCH is greater than K, the corresponding mapping table between the index value referred to by the index value of the first transmission parameter in the DCI and the first transmi...

Abstract

The invention provides a sending and receiving method and apparatus of control signaling, and an information determining method and apparatus. The method comprises the following steps: determining second information according to first information, wherein the second information comprises at least one of: the number of bits used in first control signaling to notify a first transmission parameter, an index value referred by the first transmission parameter in the first control signaling, a corresponding mapping table between the values of the first transmission parameter, the type of the first transmission parameter notified in a predetermined indication domain in the first control signaling, and location information of the bit used for notifying the first transmission parameter in the firstcontrol signaling; the first information comprises a transmission time interval between the first control signaling and a first signal and a relationship between predetermined thresholds K, and N andK are non-negative integers; and sending the first control signaling. Therefore, the problem of low resource utilization rate because the bit domains of the notification beams in the physical layer dynamic control signaling are not fully utilized in related art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for sending and receiving control signaling and determining information. Background technique [0002] As one of the core technologies of 5G, high-frequency communication provides strong support for high-speed and large-bandwidth communication in the future. However, a core problem of high-frequency communication is that the path loss is relatively large. At the same time, considering the relatively small size of the antenna, it can be formed by using multiple antennas. Beam, resistant to path loss. [0003] In order to improve system efficiency, resist beam blocking scenarios, and fast link recovery, the beam of the downlink signal can be notified through the dynamic control signaling of the physical layer. When the interval between the control signaling and the downlink signal is less than a predetermined threshold, the terminal cannot pass through the phys...
