  • Patent number: 11963146
    Abstract: A method and a device for detecting slot format indication, and a method and a device for configuring slot format indication are provided. The method for detecting slot format indication is applied to a terminal and includes: obtaining a bit length of SFI index information of a target cell or a target carrier and a slot format configuration set corresponding to the bit length; detecting the SFI index information of the target cell or the target carrier; and determining a slot format configuration corresponding to the detected SFI index information based on the detected SFI index information and the slot format configuration set corresponding to the bit length of the detected SFI index information.

  • Publication number: 20240073922
    Abstract: A DCI size alignment method includes determining, by a communication device, whether a number of DCI sizes of a plurality of DCI formats meets a DCI size budget; and in a case that the DCI size budget is not met, performing a DCI size alignment operation on the plurality of DCI formats according to a DCI size alignment rule until the DCI size budget is met. The DCI size alignment rule includes at least one of: aligning a first DCI format with DCI 0_0 and/or DCI 1_0 in a CSS; aligning the first DCI format with DCI 1_1 and/or DCI 0_1 in a USS; aligning the first DCI format with DCI 1_2 and/or DCI 0_2 in the USS; aligning DCI 1_2 and/or DCI 0_2 in the USS with DCI 1_1 and/or DCI 0_1; or aligning the first DCI format with a group common DCI format in the CSS.

  • Patent number: 9720666
    Abstract: The disclosed embodiments provide a system for densely storing strings within the memory of a software program. During operation, the system receives a set of characters to be stored in a string, wherein each character is encoded using a multi-byte public encoding. The system then stores the set of characters in the string at least in part by performing the following steps. The system determines whether every character of the set can be encoded using a first private encoding that consumes less space per character than the multi-byte public encoding. Responsive to determining that every character of the set can be encoded using the first private encoding, the system stores a particular value associated with the first private encoding in a particular field of the string. The system then stores the set of characters in the string in the first private encoding.

  • Patent number: 6683983
    Abstract: A document-inclination detector having a marginal distribution extraction section which extracts a horizontal marginal distribution and a vertical marginal distribution for the document image, a line-direction detection section which recognizes the line direction of each character string of the document image, a marginal distribution correction section which performs a threshold detection on the marginal distribution projected in the line direction, and an inclination detection section which detects the inclination of the line direction of the document image.
