摘要： Updating an uplink contention window size in a listen before talk process in a wireless communication system such as LTE may be done by the eNB if transport blocks contained in the starting subframe of a reference scheduled burst transmitted by a User Equipment are successfully decoded at the eNB. Otherwise, the User equipment adjusts the contention window size depending on information supplied by the eNB. This information identifies the first subframe in the burst whose transport block the base station was able to successfully decode. Depending on whether the User Equipment was first transmitting before or on the identified subframe, the User Equipment can either increase or reset the contention window size.

摘要： A multi-hop ad hoc communications network may allow optical communications between underwater nodes. Each node may be fitted with environmental sensors. Each node may collect data from the sensors and transmit the data to other nodes in the network according to a time division multiple access (TDMA) scheme. The data may propagate through a series of child and parent nodes to reach a master node. The master node may have a wired connection for power and data transfer.
