摘要： A base station of a code division, multiple access (CDMA) telecommunications system employs scheduling of data transmission signals to corresponding user transceivers in down-link channels of a data network. One or more user transceivers may be in communication with a base station within a cell, and each user may have a minimum data rate requirement. In accordance with the present invention, the scheduling of user data transmission follows the constraints that 1) each base station transmits to user transceivers one at a time, and 2) the base station uses full available power for the down-link channel when transmitting (for data networks only). Given a data network of users, the method of scheduling and data rates may be modeled in accordance with a linear programming problem optimized according to a predefined criterion. In addition, the present method may be employed in a hybrid CDMA/time-share system to reduce power of data channels in communication with user transceivers near the base station. A continuum of rates may be achieved based on the system signal to interference ratio (S/I). The error rate requirement of a user's down-link channel may be met provided the S/I of the channel is greater than a predetermined threshold value.

摘要： Techniques and systems for planning of wireless networks are described. A system according to an aspect of the present invention receives inputs describing traffic statistics for a wireless network and computes network specifications. The system uses the traffic statistics and network specifications as inputs to a computationally tractable model used to compute parameters for the user level performance of the wireless network. The model may suitably be a processor sharing queuing model. The model employed by the planning system allows analytical solution for the desired user level parameters, given the characteristics and conditions entered as inputs and the intended network layout characteristics. Once a set of user level performance parameters has been computed, the values of the parameters are examined to determine if they meet predetermined requirements, in an iterative process continuing until a set of specifications has been developed that produces parameters meeting the requirements.

摘要： An advantageous scheduling template slot ordering for use in establishing a scheduling order of events such as transmitting communication signals in a communication network is determined by assigning at least two initial slot positions to a particular signal class and then determining a regularity measure based on a lower bound for the regularity measure of such assignments and the remaining unassigned slot positions. This lower bound for the regularity measure of the unassigned slots is advantageously based on a hypothetical assignment of fractions of the slot positions to different signal classes instead of limiting the assignment of a slot to a single signal class. This fractional slot assignment produces a regularity measure that is better than or equal to a corresponding regularity measure based on assigning a whole slot to a particular signal class. The lower bound of the regularity measure is then compared with a threshold regularity measure, such as from a known reference scheduling template. If the threshold regularity measure is lower than the determined lower bound, then it is known that the reference template would provide a more desirable regularity of events than any template having the assigned slot positions to that particular signal class. As a consequence, other slot assignments can be compared to the reference template to rapidly identify scheduling templates with enhanced regularity characteristics.

摘要翻译： 通过将至少两个初始时隙位置分配给特定信号类，然后基于下限确定规则性度量来确定用于建立诸如在通信网络中发送通信信号的事件的调度顺序的有利的调度模板时隙排序 对于这种分配的规则性度量和剩余的未分配的位置。 对于未分配时隙的规则度量的这个下限有利地基于对不同信号类别的时隙位置的分数的假设分配，而不是将时隙的分配限制到单个信号类。 该分数时隙分配产生基于将整个时隙分配给特定信号类而优于或等于对应规则度量的规则度量。 然后将规则度量的下限与阈值规则度量进行比较，例如从已知的参考调度模板。 如果阈值规则度量低于确定的下限，则已知参考模板将提供比具有指定的时隙位置到该特定信号类别的任何模板更理想的事件规则性。 因此，可以将其他插槽分配与参考模板进行比较，以快速识别具有增强的规律性特征的调度模板。

摘要： A handover method is provided, in which a measure of signal strength is obtained between a user terminal and each of one or more candidate cells, relative to signal strength between the user terminal and a source cell. For candidate cells, a threshold is set that depends on a measure of loading of the source cell and a measure of loading of the candidate cell. For the target cell, a particular candidate cell is identified for which the measure of signal strength exceeds the threshold set for that particular cell. The user terminal is connected to the target cell. In specific embodiments, the threshold for each candidate cell depends on a load differential between the source cell and the candidate cell.

摘要： Disclosed is a method for improving call quality and capacity by integrating a dynamic channel allocation technique into an intelligent antenna system. The intelligent antenna systems includes beams which are grouped into sets, wherein each set has associated a long list and a primary short list, and each beam has associated a secondary short list. In one embodiment, long term interference levels are measured on each beam in a set of beams for a plurality of communication channels to produce the long list; short term interference levels are measured on each beam in the set of beams for a portion of the plurality of communication channels to produce a plurality of secondary short lists and the primary short list; and communication channels are assigned to a mobile-station from the portion of the plurality of communication channels based on the measured short term interference levels on each beam in the set of beams. The long list and the primary short list are based upon highest measured long and short term interference levels, respectively, for each of the plurality of communication channels across each beam in the set of beams.

摘要： A method and an apparatus for adaptively allocating available bandwidth for network users. The method is particularly beneficial in improving a viewing experience for mobile devices accessing the network, while also maximizing the number of supported users within the network. An adaptively adjusted control parameter is used in conjunction with a utility function to assign a provisional rate for users entering the network. Based on the assigned provisional rate, the method then admits prospective new network users, if enough free capacity exists to service the new user at the provisional rate.

摘要： A multiple-input, multiple-output (MIMO) communication system is configured to perform user scheduling with reduced channel station information. The system includes multiple terminals and at least one base station configured to communicate with the terminals. The base station is operative to obtain channel vector magnitudes for respective ones of the terminals, to identify a subset of the terminals based on the channel vector magnitudes, to obtain channel vector phase information for the identified subset of terminals, and to utilize the channel vector phase information to control transmission to the identified subset of terminals. The system may be, for example, a multi-user MIMO system in which the multiple terminals comprise autonomous single-antenna terminals.

摘要： The alternate destination redirection (ADR) feature (102) of telephone switching systems (101) or an equivalent is used to implement a “post-route” routing architecture having the benefits of a “pre-route” routing architecture in a network ACD (FIG. 1). The ADR feature is administered in the network (100) for individual ACD systems and individual call types at each ACD system to identify another ACD system as an alternative destination for calls of the individual call type rejected by the individual ACD system. The network distributes (302) calls to the plurality of ACD systems (110-112) on a basis (e.g., fixed percentage, round-robin) that does not require the network to know the status of the individual ACD systems. Upon having a call of an individual type routed thereto, an individual ACD system checks (304) the status of the ACD system that is administered as the alternative destination for its rejected calls of the individual type. If it determines that it can provide the better service, the individual ACD system services (314) the call. If it determines that the alternative destination ACD system can provide the better service, the individual ACD system rejects (308) the call, whereupon the network, operating under influence of the ADR feature, releases (310) the connection of the call to the individual ACD system and reroutes (312) the call to the alternative destination ACD system.
