20110029848 | ERROR CHECKING WITH DATA PRESENCE DETECTION - The present invention relates to an apparatus and a method for detecting presence of data, wherein input data is decoded using a decoder metric to obtain decoded data, and an error check is performed for the decoded data. Furthermore, a threshold value is determined based on an obtained maximum value that the de coder metric can assume for the input data, and the threshold value is compared with an actual value of the decoder metric. Presence of the input data is then decided based on results of the error check and the comparison. | 02-03-2011 |

20100290408 | Method, apparatus and computer program for user equipment access channel procedures - Access to a wireless network is attempted by sending on a random access channel RACH at a first transmit power a first preamble comprising a signature sequence that is randomly selected from a set of signature sequences. After the access attempt from sending the first preamble is determined unsuccessful, access to the wireless network is re-attempted by sending on the RACH at a second transmit power a second preamble comprising a signature sequence, in which the second transmit power is no greater than the first transmit power. Embodiments variously combine different options: the signature sequences of the first and second preambles are each randomly selected separately, or the signature sequence of the first preamble is re-used in the second preamble; the first and second transmit powers are each equal to an initial transmit power, or the second transmit power is the initial power and less than the first transmit power. | 11-18-2010 |
