12. A wc-disposable ostomy bag comprising: a flexible pouch having a forward wall and a rear wall facing a patient, said rear wall having an opening therein through which waste material from the patient can enter the pouch; a first disc with a skin-compatible adhesive rear surface and an opening therethrough; a second disc with an adhesive rear surface and an opening therethrough, said second disc being attached around its opening permanently around the opening in the rear wall of the pouch and being unattached with the pouch around its outer edge, said first disc being secured with said second disc during use by means the adhesive rear surface of the second disc forming a removable bond such that the first disc can be peeled off the second disc after the bag has been removed from the patient and such that the pouch and second disc can be disposed of in a wc and the first disc can be disposed of separately.
13. A method of collecting and disposing of body waste material, comprising the steps of: securing a bag by means of an adhesive flange to a patient around a body waste opening; allowing body waste material to enter the bag; peeling the flange off the patient so as to remove the bag; removing at least a major part of the flange from the bag; disposing of the removed part of the flange; and placing the remaining part of the bag and its contents in a wc pan and flushing it away.
14. A method according to claim 13, wherein the major part of the flange is removed from the bag by separating an adhesive bond.
15. A method according to claim 13 including the step of adding an alkali to the wc pan before flushing.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A precoding weight generation method used for a plurality of base station apparatuses in coordinating and transmitting data to a plurality of mobile station apparatuses by Joint Transmission, comprising:
generating a channel matrix having, in matrix elements, channel state information transmitted as feedback from a plurality of mobile station apparatuses undergoing spatial multiplexing for each cell that each of the base station apparatuses manages; and
generating precoding weights based on the channel matrix successively starting from a cell having the highest number of mobile station apparatuses that transmit the channel state information as feedback, wherein when data transmission is targeted for a first mobile station apparatus that transmits the channel state information as feedback as well as a weight generation target cell that is a target for generation of precoding weights, precoding weights are generated so as not to suppress interference on a second mobile station apparatus that transmits the channel state information as feedback as well as the weight generation target cell, while suppressing interference on a third mobile station apparatus that does not transmit the channel state information as feedback except the weight generation target cell.
2. The precoding weight generation method according to claim 1, wherein precoding weights are generated using the channel matrix from which a matrix element associated with the second mobile station is deleted.
3. The precoding weight generation method according to claim 1, in a cell in which precoding weights are generated subsequently, the precoding weights are generated to reduce an effect of interference due to a precoding weight for the second mobile station apparatus that is previously generated.

generating a channel matrix including, in matrix elements, channel state information transmitted as feedback from a plurality of mobile station apparatuses undergoing spatial multiplexing in a cell managed by each base station apparatus and each cell, while having a zero element in a matrix element associated with channel state information between a mobile station apparatus that does not perform feedback and the base station apparatus; and
