摘要： Techniques for scheduling logical channels for data transmission are described. In one design, a user equipment (UE) is configured with a plurality of logical channels for sending data on the uplink. Each logical channel is associated with a priority and a data buffer size. The UE maintains a token bucket for each logical channel. In each scheduling interval or when an uplink grant is received, the UE determines a bucket level (which may be a positive value or a non-positive value) for each of the plurality of logical channels. The UE ascertains logical channels with bucket levels of the same polarity and then identifies logical channels of the same priority among all logical channels with the same bucket level polarity. The UE selects at least one identified logical channel for scheduling based on the data buffer size and/or the bucket level for each identified logical channel.

摘要： Methods and apparatuses are provided that facilitate avoiding one or more wireless communication systems based at least in part on determining a level of unreliability of a reverse link channel related to a system. This can be based at least in part on determining whether the system can be accessed over the reverse link channel. If not, the wireless communication system can be avoided to conserve power utilized to perform such access attempts. Where the unreliability is temporary, however, some access attempts can be performed for systems of higher priority than a current system during the period of avoidance of one or more higher priority systems.

摘要： An operational mode of a terminal is dynamically configured to allow the terminal to receive services of interest to the terminal while potentially conserving battery power. The terminal operates in a first mode (e.g., an HRPD-only mode) and monitors only a first radio network (e.g., an HRPD network) for pages from a first data network (e.g., and IMS network) if all services from a second data network (e.g., an ANSI-41 network) of interest to the terminal is obtainable via the first radio network. The terminal operates in a second mode (e.g., an 1X-HRDP mode) and monitors the first radio network and a second radio network (e.g., a 1X network) for pages from the first and second data networks, respectively, if at least one service from the second data network of interest to the terminal is not obtainable via the first radio network. The terminal may dynamically select the first or second mode.

摘要： A wireless network planning tool simulates wireless network operation, including subscriber admission processing, based on sophisticated reverse and forward link analyses that include data fall back procedures. Subscribers are associated with an application type, where each application type preferably has maximum and minimum data rates and one or more fall back rates. During simulation, the tool may use fall back when evaluating forward and reverse communication links between subscribers and their associated sectors (base stations). A subscriber unable to close a reverse link to a given sector at a given data rate, may be re-evaluated at a lower rate under fallback procedures. Forward link analysis incorporates similar fallback procedures in forward link call admission. Fallback procedures include appropriate supplemental channel adjustments, and corresponding forward and reverse link power adjustments reflecting adjusted data rates. Forward and reverse link fallback procedures are independent and allow for different data rates for each link.

摘要： A wireless network planning tool simulates wireless network operation, including subscriber admission processing based resource reservation procedures. Simulated subscribers are associated with an application type. Application types are broadly categorized as either voice type or data type applications. Subscribers of both types are simultaneously simulated. During subscriber admission processing, the CDMA planner attempts to admit simulated subscribers to individual sectors or base stations. At each sector, a percentage of the total forward power capacity is reserved for voice users, and a second or remaining percentage may be reserved for data users. When admitting a voice user to a sector with insufficient remaining power in its voice bucket, the CDMA planner may borrow from the power bucket reserved for data users. Setting aside a power bucket for voice users at each sector insures that one or a few high data rate users do not consume all available resources in a sector.

摘要： A method for introducing hysteresis into a hard handoff decision in code division multiple access (CDMA) communications following an initial hard handoff is provided. The method introduces hysteresis when it is determined that the communicating mobile station system clock is slewing. The slewing determination follows from a calculation of the rate of change in the round trip delay (RTD) in communications with the mobile station. A calculated RTD rate of change is compared with a RTD slewing threshold, where the RTD threshold is the assumed slew rate of the mobile station. Hard handoffs are suspended as long as the calculated RTD rate of change exceeds the RTD slewing threshold. A system and apparatus to implement the above-described method are also provided.
