摘要： Briefly, in accordance with one or more embodiments, data transmitted from a transmitter is received in a downlink channel, and channel quality data is fed back to the transmitter in a first uplink channel or in a second uplink channel. Channel quality data is feedback at a lower rate on the first uplink channel and channel quality data is feedback at a higher rate on the second uplink channel in the event there is a higher amount of data to be fed back. Link adaptation may be utilized to select a transmission rate on the second uplink channel, wherein the transmission rate is selected based at least in part on a channel condition or a user location.

摘要： In a wireless communications network, a wireless device may examine the received signal to determine the strength of the received signal, and also determine the level of interference and noise. If a retransmission is needed due to a message being incorrectly received, these factors may then be processed to estimate whether the probable cause of poor reception is interference from a neighboring network. If such interference is the likely cause, the retransmission may be changed to a different time and/or to different frequencies in a subsequent frame, so that the interference from the neighboring network is less likely to reoccur.

摘要： Disclosed is a method for reducing number of bits in a Media Access Protocol (MAP) message. The MAP message comprises a plurality of information elements grouped into one of a first set of information elements and a second set of information elements. The first set of information elements are arranged in a pre-defined order and each of the second set of information elements is inserted into one of a prefix position to the pre-defined order, a suffix position to the pre-defined order and an intermediate position in-between two information elements in the pre-defined order. Each information element of the second set of information elements is then coded based on position of the information element relative to the position of the first set of information elements in the pre-defined order, thereby reducing the number of bits in the MAP message.
