摘要： RF communications received by a wireless terminal from a servicing base station are used to determine the channel quality such as reported bit error probability (BEP). The RF communications may be in the form of RF bursts that are part of a data frame. An estimated BEP may be determined from the signal to noise ratio (SNR) of the RF bursts and or a sequence of soft decisions extracted from the RF bursts, and their historical performance. The SNR maps to an estimated BEP based upon the modulation format of the RF bursts. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). The reported BEP may be based upon the estimated BEP, RBER, and/or RBER threshold. The RBER threshold may be adaptively incremented or decremented depending upon whether or not the RF communications were properly decoded. The size of the increment or decrement may be based on the channel quality.

摘要： RF communications received by a wireless terminal from a servicing base station are used to determine the BEP. These RF communications may be in the form of RF bursts that are part of a data frame. The signal to noise ratio (SNR) of the RF burst is determined and a sequence of soft decisions from the RF burst are extracted. The SNR maps to an estimated BEP based upon the modulation format and coding scheme of the RF burst. The soft decisions decode to produce a data block. When the soft decisions decoded favorably, the re-encoded data block produces a sequence of re-encoded decisions. Comparing the re-encoded decisions to the soft decisions yields a re-encoded bit error (RBER). When the decoding is unsuccessful, the BEP is estimated only upon the estimated BEP derived from the SNR. Otherwise, both the estimated BEP and RBER may be used to determine the BEP.

摘要： Idle mode power consumption reduction in wireless communications. Within a wireless communication device that is operative to communicate with any one of a number of servicing cells, paging broadcasts from more than one of these servicing cells are received and undergo only a limited amount of processing before being stored for use in subsequent processing that may be performed later. This partitioned processing allows the turning off of certain components that are not needed and/or no longer needed for determining the system frame numbers associated with various servicing cells to effectuate timing synchronization. Certain modules within such a wireless communication device may perform processing using the full capabilities of the wireless communication device to generate initially processed signal, and then after such signals are stored, then only partial processing capability of the wireless communication device may be employed, even though perhaps being slower, to complete the processing.

摘要： The invention provides a method and apparatus for end-users to allocate a communication medium locally without requiring a central arbitration device while guaranteeing access to the end-users. The end-users bid for control of an upstream data channel by concurrently transmitting auction data and address data on a first upstream signaling channel and a second upstream signaling channel. An end-user gains control of the upstream data channel when data received from the first and second downstream signaling channels match the auction and address bits. When it is determined that the end-user lost the bid, the end-user backs off from the first and second upstream signaling channels and refrains from bidding until the first and second upstream signaling channels become quiet.

摘要： The invention provides a traffic regulation technique for media that functions within access protocols by making a percentage of total communication capacity of the media unavailable to end-users as reserve capacity. This reserve capacity is released when appropriate to regulate network traffic. Thus, the traffic regulation technique regulates the traffic by adjusting the percentage of reserve capacity. The reserve capacity may be targeted to a specific type of traffic. In this way, the traffic of the communication system 10 may be regulated so that desired quality of service may be provided for specific end users.

摘要： An on-demand message system includes a profile proxy server and a plurality of message servers coupled to a wireless network for sending messages to mobile users under conditions specified by the users and sellers. Users provide profile information specifying categories and conditions for which they will receive messages. Sellers also provide profile information specifying conditions under which they want messages to be sent. A multicast message is sent and processed by target users in response to a predetermined event, e.g., location update, conveying information related to a seller for which the target users have expressed an interest in receiving.

摘要： A method to adapt channel quality indicator (CQI) reports from user equipment (UE) is provided. This involves first determining the presence of a high-speed shared control channel (HS-SCCH) signal. An estimated signal to noise ratio (SNR) is also determined. Next an SNR correction based on the presence or lack thereof of the HS-SCCH signal and the CRC checks for HS-SCCH and HS-DSCH signals are determined and applied to the estimated SNR. The CQI report is then generated based on the corrected estimated SNR. This CQI report which takes into account a corrected estimated SNR may then be used to adjust the HS-SCCH signal in an HSDPA telephony system.

摘要： This invention provides interference predictions, suitable for least interference dynamic channel assignment use or other frequency hopping uses by de-coupling the time slot assignment and the frequency hopping pattern assignment. In particular, a least interfered time slot is selected based on an aggregate interference measurement performed across an entire transmission band or a pre-specified range of frequencies in the transmission band. A user is assigned a least interfered time slot and provided an appropriate frequency hopping pattern.
