Abstract: A method selects mobile station candidates for use with virtual multiple-input multiple-output (“V-MIMO”) in a communication system. The communication system includes at least one base station and a plurality of mobile stations. At least one downlink metric is determined for a first mobile station. The at least one downlink metric is used to determine eligibility for uplink V-MIMO candidate list selection. Responsive to determining that the first mobile station is eligible for uplink V-MIMO candidate list selection, the first mobile station is paired with a second mobile station eligible for uplink V-MIMO candidate list selection.

Abstract: 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.

Abstract: A method, apparatus, and computer-readable medium encoded with computer-executable instructions for transmitting delay sensitive packets. A data rate control index is received from a mobile station for use in transmitting the delay sensitive packets to the mobile station. A transmission format is selected using the received data rate control index to form a selected transmission format. The selected transmission format uses a payload size that is smaller than a largest compatible payload size for another transmission format corresponding to the data rate control index and is selected to reduce transmission time of the packets. The delay sensitive packets are transmitted to the mobile station using the selected transmission format.

Abstract: 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.

Abstract: A method, apparatus, and computer usable program code for creating a pseudo user from a plurality of users. Packets from the buffers are combined for the plurality of users into a buffer for the pseudo user. A multi-user packet is formed using packets from the pseudo user buffer, wherein the packets have older expiration times as compared to expiration times of other packets in the pseudo user buffer. The multi-user packet is transmitted to the mobile station.

Abstract: A wireless communication network is able to perform fast reverse link scheduling by providing data to a user terminal to enable it to select parameters that a base station is to use when scheduling a reverse link transmission. The user terminal that is in hand-off and is communicating with a plurality of base stations selects among the received network measured parameters from a plurality of base station transceiver sets to prompt each base station transceiver set to utilize a set of network parameters that will not likely cause excessive interference or drop offs in any of the cells supported by the base station transceiver set with which the user terminal is communicating. Responsive to receiving the user terminal selected network parameters, each BTS determines when to transmit a burst of data, the data rate and a power level for the data for the user terminal 176.

Abstract: During a wireless call, eighth rate gating is dynamically switched off per sector for either all calls in the sector of the base station or per mobile station when a pre-determined forward link loading threshold is exceeded in that sector, and dynamically switched on eighth rate gating for either per mobile station or for all calls in the sector of the base station when the forward link loading in that sector drops below a predetermined forward link threshold.

Abstract: A dynamic distribution of traffic load across multiple carriers in a wireless communication system. The wireless communication system includes a Base Transmittal Station (BTS) and one or more Access Terminals (ATs). An arriving traffic flow is placed on the carrier pair preferably having the most excess capacity. It is determined whether the new traffic flow is symmetric or asymmetric, and whether it is a best effort (BE) or a delay sensitive (DS) flow type. A procedure is then selected and used to calculate a loading metric for each carrier pair, the new traffic flow being assigned to the carrier pair having the lowest metric.

Abstract: A plurality of base station transceiver subsystems determine whether to scale the forward link transmission power level and, if so, by what amount to control forward link transmission power level mismatch. The plurality of base stations transmit reverse link signal-to-noise ratio information and forward link transmission power levels for a specified transmission to the base station controller. The base station controller compares the reverse link signal-to-noise ratio readings received from each of the plurality of base stations to determine and select a dominant base station. The base station controller then transmits the dominant base station's forward link transmission power level for the specified transmission to each of the plurality of base stations that is communicating with the mobile station that is in hand-off. Each base station, accordingly, determines whether to scale its forward link transmission power level.

Abstract: A method and apparatus to dynamically control selectable vocoder rates in a CDMA network to optimally improve forward and reverse link capacity as necessary. To improve capacity, a number of vocoder rates are used, each requiring a different average data rate and providing a different level of voice quality. Vocoder rates are reduced to lower sector average output power thereby improving forward and reverse link capacity. Forward and reverse link loading are compared to established thresholds that, if exceeded, would trigger a forward link and a reverse link vocoder rate adjustment as necessary to improve network capacity. The forward link vocoder rate and reverse link vocoder rate may be set independently or the reverse link vocoder rate may be set as a function of the forward link vocoder rate to maintain a link balance.

Abstract: A mobile communications system includes base stations and mobile units. A power control scheme is provided in which a mobile unit can enter into a discontinuous transmission (DTX) mode. During DTX mode, the mobile unit is not transmitting traffic channels that can be monitored to determine frame errors so that the target ratio of energy per bit to noise spectral density (target Eb/No) can be adjusted. Instead, the base station monitors bit errors of bits in a pilot channel communicated by the mobile unit during DTX mode. Using this technique, the target Eb/No can be adjusted even when the mobile unit is not transmitting traffic channels, so that outer-loop power control can be performed. A number of mechanisms can also be used to detect when a mobile unit has entered DTX mode.

Abstract: A method and apparatus for providing wireless data packet call regulation and call access 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.

Abstract: Provided is a system and method for maximizing the number of communication sessions in a telecommunications network. The network includes multiple protocols that each utilize a certain number of codes and a certain amount of power. Accordingly, the desirability of each protocol may vary depending on the number of codes and the amount of power available. A code usage level and a power usage level for the network are obtained and compared to determine whether the network is using a higher percentage of the available codes or a higher percentage of the available power. If a higher percentage of codes are in use, a new session may be established using a protocol that uses relatively few codes but more power. Likewise, if a higher percentage of power is in use, the new session may be established using a protocol that uses relatively little power but more codes.

Abstract: The present invention provides for a scheduling scheme to be used with respect to a given mobile station. It is determined whether the given mobile station is or is not in soft-handoff. This is performed through examining a reduced active set. The reduced active set is based upon the active set, and the selection of the reduced active set includes considerations such as received reverse link channel signal strength. If the mobile station is in soft hand-off or with reduced active set size of greater than one, congestion control scheduling of reverse link communications from the given mobile station is utilized, using a data rate set by the congestion control of the reverse link channel. If the mobile station is not in soft-handoff or with reduced active set size of one, explicit scheduling of the reverse link communications from the given mobile station is utilized, using a data rate set by the explicit data rate control of the reverse link channel.

Abstract: A system determines an optimal set of base transceiver sets that are to transmit data over supplemental channels to a mobile station. A mobile station transmits periodic signal strength measurement message to rank the pilot signal strengths being received from the plurality of base station transceiver systems. Whenever the number of fundamental channel sectors that are active exceeds the maximum number of active supplemental channel sectors, periodic pilot strength measurement messages are transmitted by the mobile station. To improve resource usage, periodic pilot strength measurement messages are not transmitted as often as required to insure that the active supplemental channel sectors are the ones from which the strongest signals are received by the mobile station. Rather, a combination of periodic pilot strength measurement messages and calculated reverse link signal strength over spectral noise density values are used.

Abstract: Disclosed is an encoder, interleaver and splitter design approach for increasing system capacity. This is accomplished in a dual path embodiment by splitting the data stream into two subsets where one subset contains even number position bits of the original set and the other subset comprises the remaining odd bits. Each of the subsets may then be interleaved in standard fashion. This approach ensures that consecutively occurring bits in the original set are never transmitted from the same antenna and can be used to maximize the distance (and accordingly the time of transmission) between alternately occurring bits. The thought process behind this embodiment of the invention may be used to design a single interleaver as practiced in the prior art to accomplish the equivalent end result. The design process may be modified to include any number of transmission paths.
