Abstract: Techniques are provided for reducing delay during streaming transmissions. For example, a method may include receiving a stream of data segments. The method may include establishing a first group of segments based on the data segments, and generating a first table of information. The method may include transmitting the first table and the first group of segments, and establishing a second group of segments based on the data segments, the second group of segments including a partial overlap of data segments included in the first group of segments. The method may include generating a second table of information, and transmitting the second table and a collection of segments that includes data segments from the second group that were not part of the first group.

Abstract: A method for cell reselection by a wireless communication device is described. The method includes camping on a serving cell in idle mode. A neighbor cell is detected. A serving cell rank is computed for the serving cell. A neighbor cell rank is computed for the neighbor cell based on multimedia broadcast multicast service metrics. Cell reselection is determined based on the serving cell rank and the neighbor cell rank.

Abstract: This application relates to systems and methods for recovering data in multimedia file segments. A communication device may receive a multimedia file segment that includes damaged data. The communication device may replace the damaged data with dummy data to reconstruct the multimedia file segment. The communication device may then play the reconstructed multimedia file segment. Thus, by replacing the damaged data with dummy data, the communication device may play a multimedia file segment even when part of the segment may be damaged.
