Abstract: A method and apparatus for jointly decoding a first and second message is disclosed. The signaling scenario illustrated by FIG. 1 and using the codeword properties defined herein, the various embodiments may combine multiple messages under the hypothesis that the value of a message portion corresponding any subsequent observed transmission is different. Accordingly a first buffer may store the first observed message frame (509) and a second buffer may sum the LLR's of subsequent observed frames (513). In the embodiments disclosed, two decoding hypotheses are required only; a first where the two buffers are combined directly (513) and a second where the difference codeword bit LLR's of the first buffer (509) are inverted before combining with those of the second buffer (519). A maximum of N transmissions is allowed by the receiver (523), after which a decoding failure is declared.

Abstract: A mobile station (129) will have the capability to detect an impending cell change and Routing Area Update (RAU) and will send a “Request Deny” message to the network via the serving cell prior to handing over. The PTT server (131) will use the Request Deny message as an indication that an inter-SGSN RAU may be occurring. The PTT server (131) will wait for the mobile station to reappear, after handover, on a new cell. If the mobile does not reappear, an inter-SGSN RAU may be assumed and the PTT server (131) will release the floor and deny the floor to all mobile stations. This action forces all mobile stations back into idle mode and prevents them from seizing the floor. The PTT server (131) will then wait for the mobile station (129) performing the RAU to reappear on a new cell before opening the floor to all mobile stations.

Abstract: A wireless communication device employs a method for receiving a message stream on a control channel. According to one embodiment, the wireless communication device receives a message on the control channel. The wireless communication devices attempts to decode the message and, if the message is successfully decoded, adds bits of the successfully decoded message to a message attributes list. Some time thereafter, the wireless communication device attempts to decode a subsequent message received on the control channel and, if an error is detected during decoding of the subsequent message, replaces bits in the subsequent message with bits from the message attributes list to produce a modified message. The wireless device then attempts to decode the modified message.

Abstract: Various embodiments are described to address the need to lower backhaul costs for EGPRS operators while maintaining the low and constant delay characteristics they require. 20 msec TRAU frames (221-226) are still used for backhaul to maintain the low and constant delay. However, to eliminate the restriction of mapping TRAU timeslots to air timeslots (211-218) one-to-one, the TRAU slots are collectively treated as a one large 20 msec TRAU frame for a group of air timeslots. The data for the air timeslots can be packed efficiently into this giant TRAU frame, ignoring backhaul timeslot boundaries. In this way, the appropriate amount of backhaul for the carrier can be allocated and the data for the air interface timeslots more efficiently packed into the backhaul.

Abstract: A wireless communication infrastructure entity 200 and methods therein including assigning a first wireless communication terminal to one or more resources, and sending non-scheduling information to the first wireless communication terminal on an RRBP field in a downlink block based on whether information is received from the first wireless communication terminal on the assigned resource.

Abstract: A method (400) and apparatus (501) facilitate a session handover between a first site and a second site. A wireless communication unit such as a mobile station (102), user equipment (202, 302) can move from one site to another site whereupon new identifiers can be setup for the new site. If a serving node associated with the new site is also new, identifiers can be set up for the new site and the new serving node.

Abstract: A communication system assigns a combination of values of multiple combinations of values to a first control channel parameter and a second control channel parameter. Based on the values assigned to the first and/or second control channel parameters, repeat periods corresponding to each of a first, second, and third control messages are determined. New combinations of values of the multiple combinations of values are then assigned to the first and second control channel parameters and new repeat periods corresponding to each of the first, second, and third control messages are determined in association with each new combination. Optimal repeat periods corresponding to each of the first, second, and third control messages are then selected from among the repeat periods determined with respect to each combination of values. Based on the selected repeat periods, an optimal combination of values is selected for each of the first and second control channel parameters.

Abstract: To address the need for a communication infrastructure and method to speed uplink data setup, the present invention provides for the assignment of uplink packet data resources by basestation transceiver systems (BTSs) without the need to communicate with any packet control unit (PCUs) first. The present invention accomplishes this by reserving packet data resources before they are needed or requested and providing them to BTSs for assignment. Thus, BTS-PCU communication occurs in the period before an uplink connection is needed and after uplink data is established, effectively eliminating the BTS-PCU delay from uplink data setup. Moreover, the present invention provides for the transmission of transmit allowance messages before an uplink request is made by the communication unit, further reducing uplink data setup time.

Abstract: During data transmission to a remote unit (113) utilizing a supplemental, high-speed data channel (105), data transmission stops due to all data being communicated to the remote unit (113) or because a time period for transmission has expired. In the situation where all data has been transmitted to the remote unit (113) the remote unit (113) will delay dropping the data channel (105) for a predetermined period of time. In the situation where a time period for transmission has expired, the remote unit (113) will continue transmitting into a frame assigned to another remote unit.

Abstract: A radio communication system (100) employs a method (300) and apparatus (103) for providing chronological information to a communication unit (103). A base site (101) of the radio communication system (100) determines (303) the chronological information (e.g., time and date). The base site (101) transmits (305) the chronological information in a portion of a system control signal (107) to the communication unit (103). The communication unit (103) receives (311) the chronological information and maintains (313) the chronological information for use (315, 317) by a user of the communication unit (103).

Abstract: The present invention provides a fair and efficient method (1000), device/microprocessor (500, 600) and computer software for utilizing the downlink channel in a TDMA packet-switched communication system supporting both single slot subscriber units and multiple slot subscriber units which both use the same air-interface protocol.

Abstract: The present invention provides a method (400, 500, 600, 700, 800, 900, 1000) and device (1100, 1200, 1300) for contention for channel access to single-slot subscriber units that are capable of transmitting and receiving data on one time slot per TDMA frame, allowing contention for channel access on any one of the available packet time slots and transmission on the time slot where contention is won. Thus, the present invention eliminates a requirement for a subscriber unit to be assigned to a particular time slot for contention, thereby eliminating the problem of performing load balancing on the time slots.

Abstract: A novel scheme efficiently indicates to a plurality of users which user has been granted access to a multi-access packet channel. Transmission and reception of a predetermined limited number of echo bits per timeslot reduces bandwidth usage, and over the duration of a packet, these bits are equivalent to a variable length random identification number which is used for identifying which user has been granted access.
