摘要： According to embodiments of the present invention, multiple frames or sub- frames on an uplink channel may be aggregated into one logical unit for demodulation and decoding to allow one data packet to span over multiple frames. Multi-frame aggregation is enabled by modifying the uplink resource allocation messages transmitted to the user terminals. The multi-frame resource allocation message includes a BEGIN FLAG field indicating whether a corresponding frame is the first frame in a multi-frame allocation and a REMAINING RESOURCES field to indicate the number of units (e.g., slots or frames) remaining in the multi-frame allocation.

摘要： A method and apparatus for decoding turbo encoded data. A first turbo decoding iteration is performed (42) to produce a most likely sequence of symbols, each symbol having an amplitude value and a positive or negative sign. The sequence of symbols is error checked (43), and if an error is detected, the apparatus forms a next most likely sequence by reversing the positive or negative sign of the symbol having the smallest amplitude. If an error is again detected (47), additional sign reversals are performed on symbols with larger amplitudes, and on multiple symbols. Each modification is error checked. If none of the modifications produce an error-free sequence, and a maximum number of modifications are performed (48), the apparatus performs another turbo decoding iteration to produce another sequence of symbols. The process is then repeated until an error-free sequence is produced or a maximum number of iterations are performed (49).

摘要： A method is described herein that enables a Selective-Per-antenna-RateControl (S-PARC) technique to be effectively implemented in a wireless communications network (e.g., HSPDA third generation communications network). In one embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a "full" feedback signal to a base station that analyzes the "full" feedback signal and determines which mode and transmission rates(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device. In another embodiment, the method enables the S-PARC technique to be implemented in the wireless communications network by enabling a mobile terminal device to generate and transmit a "reduced" feedback signal to a base station that analyzes the "reduced" feedback signal and determines which mode and transmission rate(s) are going to be used to transmit data substream(s) from selected transmit antenna(s) to the mobile terminal device.

摘要： A wireless telecommunications network supplies a semi-persistent resource that a wireless station can use for special purposes such as a retransmission of packets for ARQ purposes or a control signal. The semi-persistent resource can be allocated by the system to other terminals if, e.g., a retransmission is not required. Since a retransmission is generally performed in response to a NACK received from a base station, the NACK may itself serve as a token that permits the wireless station to use the semi-persistent allocation. Thus, the technology includes, e.g., a method for resource allocation on a semi-persistent basis and efficient signaling for the usage of such allocation.

摘要： Methods and apparatus for allocating time-frequency resources to mobile terminals in a wireless communications system in which time-frequency resources may be selectively used according to a first multiple-input multiple-output (MIMO) transmission scheme or a second MIMO transmission scheme that differs from the first MIMO transmission scheme. An exemplary method comprises, for at least a first scheduling instance, identifying a first group of mobile terminals corresponding to the first MIMO transmission scheme and a second group of mobile terminals corresponding to the second MIMO transmission scheme, allocating time-frequency resources in a first pre-determined time-frequency zone exclusively to mobile terminals belonging to the first group, and allocating time-frequency resources in one or more additional pre-determined time-frequency zones to one or more mobile terminals belonging to the second group. This method may be implemented in a base station of a WiMAX system, for example.

摘要： Teachings presented herein offer reduced computational complexity for symbol sequence estimation, and also provide for the generation of soft bit values representing the reliability of that estimation. A demodulator is configured to generate these soft bit v allies by identifying a candidate value for each symbol in the sequence which is more likely than at least one other in a defined set of candidate values. Based on the candidate value identified for each symbol, the demodulator forms a reduced set of candidate values for the symbol by selecting as many additional candidate values from the defined set as are needed to have complementary bit values lot each bit value in that identified candidate value The demodulator calculates soft hit values for the symbol sequence based on a sequence estimation process w hose state space for each symbol is constrained to the cot responding reduced set.

摘要： A communications network (10) comprises a base station (28) and a wireless terminal (30) which communicates over an air interface (32) with the base station (28). The base station (28) makes an identification or categorization of the wireless terminal (30) during a ranging procedure. The identification or categorization concerns whether or not the wireless terminal (30) has an enhanced capability. The categorization is made on a basis of a transmission characteristic of the wireless terminal (30). The base station (28) can then communicate with the wireless terminal (30) in a manner to utilize the enhanced capability of the wireless terminal (30).

摘要： The technology provides a frame handler, a controller, and a frame structure design for a new radio communications system that provides backward compatibility with an existing or legacy radio communications system with lower signal bandwidth. Data to be transmitted to the new and legacy radio terminals is processed into a frame using a frame format that is compatible with both the new radio access technology system and the legacy radio access technology system so that both types of radio terminals may receive and extract data from the frame intended for each of those radio terminals. The format allows new and legacy radio terminal communications across the different bandwidths employed by the new and legacy systems.
