Abstract: Techniques are described for wireless communication. A first method may include classifying feedback received for a first downlink transmission over a shared radio frequency spectrum band; identifying an interference parameter for a subsequent downlink transmission; and scheduling the subsequent downlink transmission based at least in part on feedback classified in a feedback category associated with the identified interference parameter for the subsequent downlink transmission. The feedback may be classified in one of a plurality of feedback categories, and the classifying may be based at least in part on an interference parameter for the first downlink transmission. A second method may include identifying an interference parameter for a first downlink transmission received over a shared radio frequency spectrum band; generating feedback for the first downlink transmission; and sending, to a base station, the feedback along with an indication of the interference parameter.

Abstract: Pitting corrosion of stainless steel occurs in solutions of organic acid, such as tartaric acid, in an electrolyte solution with methanol. However, methanolic solutions containing at least one organic halide and at least one organic hydroxyl-acid and some water provide reduced pitting corrosion of stainless steel. The organic hydroxyacid may be a hydroxy acid containing 2 to 10 carbon atoms with at least one hydroxyl group and at least one carboxylic acid group, in a non-limiting example, glycolic acid. The pH of the methanolic solution may range from about 3.5 to about 8.

Abstract: Transfer of Multimedia Broadcast/Multicast Services (MBMS) over a Single Frequency Network (MBSFN) service and idle mode unicast service for a mobile entity from a source base station to a target base station may be managed by a base station or mobile entity of a cellular wireless communications system (WCS). Operations related to the transfer may include obtaining an MBMS status of the mobile entity, and/or obtaining MBMS support information for the base station. A network entity may facilitate MBMS discovery by a mobile entity, by transmitting a data element to the mobile entity including service identifiers mapped to corresponding cell identifiers to indicate respective MBMS services to be broadcast in an WCS area on adjacent cells identified by respective ones of the cell identifiers. The MBMS services may be broadcast within the WCS area using the adjacent cells previously indicated in the data element.

Abstract: Additional improvements to the design of enhanced physical random access channel (ePRACH) procedures are disclosed for communications systems having contention-based shared spectrum including unlicensed frequency bands. The additional improvements address the uncertainty of transmission in listen before talk (LBT)-based communications and cooperation with other radio access technologies competing for the same frequency spectrum.
