摘要： In a communcations system, communications resources are allocated in a dynamic, 'as needed' fashion. No explicit signaling is needed to exchange information pertaining specifically to an allocated communications resource. Instead, resources are implicitly allocated by using one or more parameters known to both the radio access network and mobile station that are more or less unique to the mobile station. Such parameters are used to generate or address a communications resource for use by the mobile station. The parameters might, for example, be information readily acquired or communicated as a result of a synchronization procedure, a mobile station registration procedure, a mobile station access procedure, a paging procedure, etc. Example parameters may include a system frame number, a system identification, a radio access network identification, a base station identification, a cell identification, a mobile station-associated signature, an access reference number corresponding to the mobile station, a time instant when an acknowledgment message is received, etc.

摘要： The present invention discloses a method for transmitting a plurality of information streams (10) having variable data rates. A plurality of information streams (10) are multiplexed together into a common information frame (25). The information is channel encoded and multiplexed with a number of overhead bits (67) including encoding information on the multiplexed frame (65). The multiplexed frame is then demultiplexed into at least one channel frames (75) that are each transmitted over a separate code channel such that the first code channel always includes the overhead bit data.

摘要： A method and system are disclosed for facilitating the timing (e.g., the known relative timing differences) of base stations (Bss) (BS1, BS2, and BS3) in asynchronous CDMA mobile communications systems (200). A plurality of mobile stations (MSs) (MS1, MS2, and MS3) measure the relative time differences between various pairs of BSs, and these measurements are stored by the BSs. A source BS sends (106) to an MS, in a neighbor list message, estimates of the relative time difference between the source BS and each of the BSs on the neighboring cell list. Each BS on the list can maintain a relative time difference estimate table, which can be updated continuously from the reports received from MSs. Subsequently, the BSs can send entries from this table to the MS in the neighbor list message. Using this novel technique, the BSs have known relative timing differences. Consequently, when the MS initiates a cell-search for a candidate BS, the MS already has an estimate of the timing of that BS as compared to its source BS. As such, the resulting cell-search procedure has a lower level of complexity and thus can be accomplished much quicker than with prior procedures. In addition, the relative time difference estimates can be compared with corresponding time differences that are measured by a second mobile station. Based on this comparison, the propagation delays of signals between the second MS and various BSs can be calculated to determine the position of the second MS.

摘要： A method is disclosed for processing mobile-originated random access requests (RA1, RA2, RA3) in a mobile telecommunications system (10) that randomly selects new signatures (102) for re-transmissions in the event that collisions have occurred. As such, the random access re-transmissions (RA1, RA2, RA3) are randomized over the signature domain instead of just over the time domain. Consequently, the disclosed invention significantly shortens random access delays caused by collisions or erroneous arrivals at base station receivers (14), and also significantly reduces the interval between random access re-transmissions (Td).
