摘要： The present invention provides an improved RACH access burst arrangement and frame structure. That is, the invention provides methods and apparatus for supporting more than one access burst length in the UMTS access channel structure. Preferably, two access burst lengths are supported, e.g., 5 ms and 10 ms. Such an arrangement is advantageous in applications where it is beneficial to have fast access latency such as, for example, voice or other forms of real-time traffic. Also, the invention provides methods and apparatus for supporting multiple frame sizes. It is to be appreciated that further enhancement to access latency can be obtained by having the UMTS physical layer support multiple frame sizes. The access burst signal transmitted by a remote terminal over the RACH may be an access request or data packets in the case where the RACH is being utilized for UMTS short message services.

摘要： In a Universal Mobile Telecommunications System (UMTS) based wireless system, a channelization code-tree is partitioned into two sets: a permanent set and shared a shared set. Those codes in the permanent set are assigned to low data rate users for the duration of a session, or connection. Those codes in the shared set are assigned to high data rate users on a frame-by-frame basis using a downlink shared (DSCH) channel. The partition boundary between the permanent set and the shared set can be dynamically shifted based on traffic conditions.

In another aspect of the invention, a method for use in a UMTS transmitter of power ramping a signal transmitted by the transmitter and received by a UMTS receiver includes increasing a signal strength of the signal by a first predetermined amount when informed by the receiver that the signal is greater than or equal to a first power threshold value but below an initial detection threshold value, and re-transmitting the signal.

摘要： The present invention provides methods and apparatus for providing access priority in a MAC protocol of a communications system such as, for example, with respect to UMTS RACH. Particularly, the invention introduces several access priority methodologies including: (i) random chip delay access priority (RCDAP); (ii) random backoff based access priority (RBBAP); (iii) variable logical channel based access priority (VLCAP); (iv) UMTS-specific variable logical channel based access priority (VLCAP′); (v) probability based access priority (PBAP); and (vi) retransmission based access priority (REBAP). Each methodology associates some parameter or parameters to access priority classes in order to influence the likelihood of a remote terminal completing a successful access request to a base station.

摘要： Methods and systems are provided for improving frame selection in wireless communications networks. During decoding of a frame, a base station generates an error burst representation associated with error bursts and stores the representation within the frame, thus forming an enhanced frame. The base station then transfers the enhanced frame to a network controller. A frame selection unit (“FSU”) within the network controller thereafter applies frame selection to the enhanced frame. The error burst representation can be analyzed to determine the quality of the enhanced frame. A “combined” frame, generated by combining an “acceptable” portion of the enhanced frame and an acceptable portion of a copy of the enhanced frame, can then be generated to substantially eliminate errors. The present frame selection methods and systems enable superior quality frames to be passed on to higher layers in a network's communications protocol (hereafter collectively referred to as “network”).

摘要： An overload or congestion condition on an access medium (24) of a communication network (22) is indicated by at least one condition that indicates an amount of access attempts on the access medium (24) corresponds to congestion or overload of a capacity of the access medium (24). Example conditions in disclosed embodiments include an occupancy level of the access medium, an average number of access probes associated with successful access attempts, a relationship between received power and interference, an emergency condition and network configuration or maintenance procedures. In a disclosed example, when congestion or overload occurs, at least one technique is implemented to reduce the congestion or overload for stabilizing the access medium. Disclosed example techniques for this include throttling the number of access attempt by reducing the number of users making access attempts or the frequency of user access attempts. Another example technique includes adjusting at least one access medium parameter that will reduce the access attempt traffic.
