Abstract: Disclosed are Lactobacillus rhamnosus strain 753 and uses thereof, a silage additive and silage. Lactobacillus rhamnosus strain 753 is deposited in China General Microbiological Culture Collection Center with an accession number of CGMCC 18233. Lactobacillus rhamnosus strain 753 can improve the quality of silage in a high-temperature and high-humidity region, and the silage processed by Lactobacillus rhamnosus strain 753 has good stability and low pH, low aflatoxin B1 content and less dry matter loss. In addition, secondary fermentation can be avoided in the silage processed by Lactobacillus rhamnosus strain 753 when a silo or bale for silage is opened.

Abstract: A method includes allocating channels in a fast-feedback channel region for a plurality of devices, and transmitting to the plurality of devices at least one bitmap defining fast-feedback uplink channel allocations for individual ones of the plurality of devices. In one embodiment a plurality of bitmaps are transmitted, the plurality of bit maps together informing individual ones of the plurality of devices of permission to use none, one or more than one particular fast-feedback channel. In this case each bitmap includes a plurality n of bit positions corresponding to n indices, where each device is identified by an associated one of the n indices, and where a bit at an index value p in a first bitmap and a bit at the same index value p in a second bitmap, when concatenated together, equal a number of fast-feedback uplink channels that are allocated to a particular device associated with the index value p.

Abstract: The present invention provides a method, a mobile terminal device and a system for determining a transmission power factor. During an uplink of data between a mobile terminal device and a base station via a code division multiple access (CDMA) system supported by automatic repeat request (ARQ) first transmission containing original data and re-transmissions of different order containing supplementary information are communicated. The i-th re-transmissions are based on the automatic repeat request (ARQ). The transmission power factor to be determined is operable with an i-th re-transmission. A first and a second error quantity are obtained from an evaluation of status information items received in accordance with the automatic repeat request (ARQ). The first error quantity and the second error quantity allow for deriving an i-th error ratio so as to calculate a transmission power correction factor.

Abstract: The present invention provides a method to enhance the RACH message transmission of a wireless communication systems. Therefore the known RACH procedure for uplink transmission is extended by additional steps in order to allow the usage of adaptive transmission parameters for uplink transmissions, preferably the usage of adaptive modulation and coding (AMC). This is advantageous because studies in high-speed downlink packet access show the possibility to increase the data rate of a downlink shared channel. The method according to the invention introduces a new RACH message preamble and enables the base station to estimate suitable adaptive transmission parameters like an AMC setting according to the current transmission conditions which are used during the RACH message transmission.
