摘要： System and method for optimally updating a neighbor set for use by a mobile unit during soft handoff of the mobile unit in a CDMA cellular telephone environment is disclosed. A two-step process is used to ensure that the individual neighbor sets of active set members are combined in a manner such that only pilots representing the more important sectors are included in the updated neighbor set and pilots representing the less important sectors are excluded therefrom. In the first step, active set members whose RTD is more than twice as great as an OWD threshold are eliminated from consideration. In the second step, the neighbor set of the mobile unit is updated using the sectors included in the individual neighbor sets of the active set members that were not excluded by the first step, wherein those sectors are included in the updated neighbor set according to the number of individual sets in which they are found and their priority within those sets. In an alternative embodiment, a combined carrier-to-interference ratio for each of the individual neighbor set members is also used in updating the neighbor set. In an alternative embodiment, the individual neighbor set of the active set member having the shortest RTD is used as the updated neighbor set.
摘要翻译：公开了用于在CDMA蜂窝电话环境中的移动单元的软切换期间最佳地更新由移动单元使用的邻居集合的系统和方法。使用两步过程来确保主动集合成员的各个相邻集合的组合方式使得只有代表更重要的扇区的导频被包括在更新的邻居集中，并且排除代表较不重要的扇区的导频。在第一步中，考虑到RTD是OWD阈值的两倍以上的活动集成员。在第二步骤中，使用未被第一步骤排除的活动集成员的各个相邻集合中包括的扇区来更新移动单元的邻居集合，其中，根据找到他们的个人集合的数量及其在这些集合中的优先级。在替代实施例中，用于每个单独的相邻集合成员的组合的载波干扰比也用于更新邻居集合。在替代实施例中，具有最短RTD的活动集合成员的个体邻居集合被用作更新的邻居集合。

摘要： The present invention supports a scheduling protocol on a wireless communication network to transmit data packets stored in a queue from a user. Two performance metrics are generated and summed to provide a priority. The performance metrics are based on the delay for the data packets stored in the queue and the rate that the data packets can be transmitted on the network. The user with the higher calculated priority for the current time slot has its-data packets transmitted.

摘要： A method increases spectral efficiency in a communication system. The communication system includes at least one mobile station and is capable of transmitting messages encoded according to a plurality of available modulation coding schemes ("MCSs"). Each available MCS includes a modulation scheme and an effective coding rate. The MCSs are indexed according to increasing complexity. A signal-to-interference ratio ("SINR") is determined which is sufficient to satisfy a predetermined frame error rate ("FER"). A first MCS and a corresponding amount of transmissions needed to satisfy the predetermined FER at the SINR using the first MCS are determined. The first MCS has a higher effective coding rate than a second MCS. The second MCS sufficiently satisfies the predetermined FER at the SINR in a single transmission. A message encoded according to the first MCS is transmitted through the communication system using hybrid automatic repeat request ("HARQ")

摘要： A method and apparatus for providing wireless data packet call regulation and call admission control for wireless Voice over Internet Protocol (VoIP) communications in a wireless network. A first and second time stamp is generated upon the reception and successful transmission of a data packet. A packet delay is determined based upon the first and second time stamps. At least one average delay metric is used to determine whether to provide new call access based on the at least one average delay metric. Another aspect of the present invention is to block a class of users based, in part, on the average sector delay for each user subscriber class. If the average sector delay is greater than that allowed for a class of users, users of that class are denied access. A delay quality of service (QoS) block metric is used to determine if an individual user should be force dropped.
