  • Publication number: 20200099489
    Abstract: A method for configuring a reference signal in a wireless communication system includes a base station receiving a plurality of uplink sequences from an uplink channel and performing an optimal combining procedure on the plurality of uplink sequences to output a result of combined uplink sequences. The base station determines channel signature information based on the combined result, and detects a plurality of complex signals at peak positions from the plurality of uplink sequences based on the channel signature information. The base station further estimates a first correlation level based on the plurality of complex signals and coherently accumulates a second correlation level based on the first correlation level. A density of the reference signal and MCS based on the second correlation level is then determined.

  • Patent number: 8057555
    Abstract: An outer casing of a non-aqueous electrolyte battery is capable of being mass-produced as well as thin and resistant to damage. The outer casing 4 comprises a casing body 4a and a cover 4b. After being internally packaged, a non-aqueous electrolyte battery 2, e.g. a lithium-ion polymer secondary battery, is sandwiched between the casing body 4a and the cover 4b, which are then joined together integrally. The cover 4b is formed from a film-shaped sheet material 4c of a synthetic resin to make the outer casing 4 thin. The casing body 4a and the cover 4b have a casing body outer peripheral frame 9 and a cover outer peripheral frame 10, respectively, formed by injection molding. Joint portions of the casing body 4a and the cover 4b have stepped portions 9a and 10a, respectively. The stepped portions ensure the mechanical strength against shock and impact. With this structure, the outer casing 4 is resistant to damage.

  • Publication number: 20070287063
    Abstract: By using a DI molding method or a roll forming method, a casing member made of a thin cylindrical metal pipe is formed and molded so as to almost coincide with a shape of a battery element, thereby forming an outer casing. A power generating element to which a circuit board has been connected is enclosed in the outer casing and opening portions of the outer casing are closed by a front cap and a rear cap formed by, for example, a resin molding, thereby forming a battery pack. The power generating element is used by externally covering the battery element with a laminate film or the battery element is enclosed as it is into the outer casing. To suppress the penetration of the moisture into the battery, it is also possible to mix a moisture trapper for absorbing the moisture into a resin material of the front cap and rear cap and suppress the penetration of the moisture.
