摘要： The technology disclosed provides the ability for a subframe to be configured as a "flexible" subframe. As a result, at least three different types of sub frames in a TDD system may be configured: a downlink ("DL") subframe, an uplink ("UL") subframe, and a "flexible" subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

摘要： A communication device has a first transceiver (Bluetooth) that operates in a first communication system in the presence of or collocated with a second transceiver (e.g. LTE, WIMAX) that operates in a second communication system that is unrelated to the first communication system. A scheduler of packets for transmission by the first transceiver uses information about when the second communication system will be transmitting a signal that will interfere with reception by the first transceiver, and schedules data for which re-transmission is not essential in those time slots in which an implicit NACK is expected due to the second transceiver's operation. The first transceiver support a first type of link having a QoS requirement requiring retransmission and a second type of link having a QoS requirement which permits but does not require retransmission.

摘要： A wireless communication node (10) dynamically estimates passive intermodulation (PIM) interference coupled into the node's receive path from the transmission of a composite signal through the node's transmit path. The node (10) then cancels the estimated PIM interference in the receive path. In some embodiments, the node dynamically estimates the PIM interference as a function of the composite signal that models PIM interference generation and coupling in the node (10) according to one or more coefficients (30). The coefficients (30) may be determined by transmitting a test signal (34) during a test stage, when the node (10) is not scheduled to receive any signal. Later, when the composite signal (18) is transmitted, the node (10) uses the coefficients (10) to dynamically estimate and cancel the resulting PIM interference.

摘要： A method of demodulating voice or data and control information in systems that support multiple modulation schemes modulates voice or data using a first linear modulation scheme, such as 16QAM modulation scheme, and modulates control information using a second linear modulation scheme, for example, QPSK modulation scheme, that has the same symbol rate as that of the first modulation scheme. The first linear modulation scheme has a higher modulation level than the second linear modulation scheme. Information modulated using the second linear modulation scheme, which uses a reduced signal set of the first linear modulation scheme, are demodulated using the same demodulator that is used for demodulating information modulated using the first linear modulation scheme. Also, in-band signalling information within a traffic channel, such as stealing flags, are modulated using the second modulation scheme.

摘要： A method of communicating control information in systems that support multiple modulation schemes for communicating voice or data and control information. To provide backward compatibility dedicated control channels use the modulation scheme used in current systems, for example GMSK modulation scheme. Traffic channels and associated control channels use linear modulation schemes that have the same symbol rate. The modulation scheme of the associated control channel uses a reduced signal set of the modulation scheme used for traffic channels. Also, an in-band signalling procedure is used to indicate to a receiving station the modulation type, channel coding and speech coding used for a transmitted burst.

摘要： A bit rate indicator for use in the mobile station of a radiotelephone system which provides an indication to the user of the maximal bit rate available in the current cell and the predicted bit rate the user can expect to achieve if a session were initiated in his present location. In calculating the maximal bit rate, the mobile station receives a message from the base station indicating the base station's capabilities, such as support for multi-slot operations and coding/modulation schemes. The mobile station then uses the base station's capabilities along with its own capabilities to determine the maximal bit rate. In calculating predicted bit rate, the mobile station measures the link quality of at least one channel and based on, at least one of, the measured link quality and mobile's capabilities, determines a predicted bit rate the user would achieve in his present location. Both the maximal and predicted bit rates can be outputted on the mobile station for comparison by the user. This information can be used to effectively direct the user to the location in a cell with the best link quality. The present invention may be especially useful when using a mobile station to interface with the Internet.

摘要： Apparatus (92), and an associated method (200), for estimating an interfering-signal component portion of a receive signal received at a receiver (76). The training sequence associated with the interfering-signal component portion is determined (94), even without prior knowledge of the training sequence associated with such interfering-signal component portion. Once the training sequence of the interfering-signal component portion is determined, the receive signal is selectively (108, 136), jointly detected utilizing a joint detector (118), the interfering-signal component portion of the receive signal is better able thereby to be canceled or otherwise suppressed.
