摘要： Techniques for performing joint detection with a common midamble for downlink transmission are described. In one design, a user equipment (UE) may obtain samples for a burst transmitted by a Node B on the downlink. The burst may include at least one data field and a common midamble. The UE may derive a channel impulse response estimate for each of multiple orthogonal codes based on (i) a channel impulse response estimate derived based on samples for the common midamble and (ii) a traffic-to-pilot ratio (T2P) estimated for that orthogonal code based on the samples for burst. The UE may perform joint detection, for the multiple orthogonal codes, on samples for the at least one data field based on the multiple channel impulse response estimates.

摘要： Systems and methodologies are described that facilitate increasing throughput in a time-division duplexed CDMA wireless communication environment. A set of orthogonal Walsh code sequences can be assigned to a first group of users in a network sector, and a duplicate set of orthogonal Walsh code sequences can be assigned to at least a second group of users in the sector. A number of receive antennas equal or greater than to the number of duplicate code sets being assigned can be deployed to linearly scale sector capacity to meet user demand. Additionally, user devices employing duplicate Walsh code sequence assignments at a base station serving the sector can be distinguished from each other, and timing offsets between such users can be enforced to mitigate any jamming effect at the base station receiver. Still furthermore, user device channel requirements in the sector can be continuously evaluated and an appropriate number of antennas can be dynamically deployed to provide scalable service to all such user devices.

摘要： Managing radio resources across dual networks includes a wireless mobile device connecting to a first wireless network using a first radio access technology. The wireless device may notify the first network of a capability to be temporarily non-responsive to the first network while maintaining a signaling connection to the first network. The wireless device may communicate with a second network. The wireless device may return to communicating with the first network subsequent to communicating with the second network, and in response to communicating with the second network for less than a predetermined amount of time, the wireless device may send a scheduling request to the first network. In response to receiving a grant acknowledgement from the first network, the wireless device may send a buffer status report that includes a value such as zero to indicate that the wireless device has returned to and can communicate with the first network.

摘要： Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use either a single antenna mode or a multiple antenna mode such as a dual antenna mode in monitoring the paging channel. In the single antenna mode, a single active antenna is used to receive paging signals. In the dual antenna mode two antennas are simultaneously used to receive paging signals. The device may choose which antenna mode to use based on signal quality measurements and history information on successfully received paging signals.

摘要： A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.

摘要： A mobile wireless device adapts receive diversity during discontinuous reception based on downlink signal quality, page indicators and page messages. When the downlink signal quality exceeds a pre-determined threshold, the mobile wireless device decodes a page indicator channel through an initial antenna, and otherwise, decodes a paging channel through the initial antenna without decoding the page indicator channel. The mobile wireless device switches to decoding the paging channel through an alternate antenna when a page indicator decodes as an erasure. When a paging message received through a single antenna decodes with an incorrect error checking code, the mobile wireless devices enables receive diversity through multiple antennas for subsequent decoding. The mobile wireless device switches between single antenna reception and multiple antenna reception based on tracking multiple consecutive error checking code failures and successes.

摘要： Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use a selected one of the multiple antennas in monitoring the paging channel. If received signal quality is satisfactory, the device may maintain use of the selected one of the multiple antennas for subsequent wake period monitoring of the paging channel. If received signal quality falls below a threshold or is otherwise indicated to not be satisfactory, the device may switch to use of a different one of the multiple antennas in monitoring the paging channel. Other criteria may also be used in controlling the switching between antennas for paging channel monitoring.

摘要： A method and apparatus for controlling AMC in an OFDM communication system in which an entire frequency band is divided into a plurality of sub-carrier bands. In the AMC controlling method, power and a number of transmission bits are calculated for each of the sub-carriers in a predetermined method for each of coding methods available in the OFDM communication system. A data rate for each of the coding methods is calculated based on the number of transmission bits and the power for each sub-carrier. A coding method having a highest of the calculated data rates is selected and a modulation method is determined according to a number of transmission bits in the determined coding method.
