This invention relates to novel partially dehydrated amorphous calcium sodium pyrophosphate and to the production of such compounds. Also this invention relates to the process for the use of these compounds to gel aqueous solutions of some polyols and to the gels obtained therefrom.
摘要:
In a mobile wireless network system including a plurality of nodes communicating with each other, a node attempting to transmit data finds useable resources through performing carrier sensing on packet data unit (PDU) slots and transmits data through the found resources. A node attempting to receive data finds useable resource through performing carrier sensing on acknowledge (ACK) slots and receives data through the found resources.

Provided is a frame structure designed for distributed access control and OFDMA transmission in a wireless mesh network. Also, a communication method and a network node based on the frame structure are provided. Mesh nodes included in the wireless mesh network may use the frame structure and thus, may have a high prospect of transmitting a network configuration information message and scheduling information for obtaining a resource. Also, a scheduling process of the mesh nodes may be completed within a short period based on the frame structure.

A mobile terminal and a method of displaying a menu thereof are provided. The method includes displaying a list of upper-level menus in an order on a display screen, displaying a first upper-level menu at an upper end of the display panel, a second upper-level menu that is next to the first upper-level menu in the order at a lower end of the display screen, and lower-level menus of the first upper-level menu in a list between the first upper-level menu and the second upper-level menu in response to selection of the first upper-level menu from the list of upper-level menus, and executing a selected lower-level menu in response to selection of one of the lower-level menus.
摘要:
The present invention provides a method for resource allocation in a wireless communication system. In the method for resource allocation, a scheduler of a base station decides on a modulation scheme and an encoding scheme according to channel quality information (CQI), and decides on a number of allocated resource blocks according to transmission data size referring to a table of resource block allocation. The table of resource block allocation presents a number of allocated resource blocks and a number of transmission bits according to the number of allocated resource blocks.
