摘要： An access node is configured to adapt uplink power control procedures based on the device attributes of a wireless device. The device attributes may, for example be the mobility, energy profile, or characteristic traffic pattern of the wireless device. The adaptive uplink power control procedure may be used to minimize or reduce power consumption, to improve resource utilization efficiency, or to reduce interference levels.

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： At least some reference symbols dedicated to a particular communication device are transmitted in resource blocks allocated to other devices. This way, reference symbol assignments are not unduly restricted by other constraints placed on the boundary elements of a resource block. According to an embodiment, data and reference signals are transmitted by transmitting a resource block allocated to a first communication device. The resource block includes a plurality of resource elements, each resource element corresponding to a modulation symbol. At least one reference symbol associated with the resource block and dedicated to the first communication device is transmitted in a resource block allocated to a second communication device. On the receive side, the communication device can perform channel estimation based on reference symbols dedicated to the device that are transmitted in resource blocks allocated to the device and in resource block(s) allocated to other communication device(s).

摘要： Transmitted signals are modified to facilitate the emulation of circular convolution in non-contiguous transmission environments. These modified signals may be derived from well-known signature sequences. In an exemplary method, a tail portion of a final segment of a base signal is prefixed to an initial segment of the base signal, to form a first transmit segment. One or more additional transmit segments are formed by prefixing, to each of the one or more segments of the base signal other than the initial segment, a tail portion of the immediately preceding segment of the base signal. The transmit segments so formed are transmitted in respective ones of the plurality of non-contiguous transmit-time intervals. Corresponding methods for receiving the transmitted segments and reconstructing the base signal are also described, as are corresponding transmitting and receiving apparatuses.

摘要： In an orthogonal frequency division multiple access communication system, a base station transmits a quick paging signal simultaneously with a synchronization signal during the same transmission symbol time period. Even though these different signals are transmitted during the same transmission symbol time period, a periodicity of the synchronization signal is maintained to facilitate rapid and cost-effective synchronization by subscriber stations with the base station. The quick paging signal alerts subscriber stations about whether to stay awake for a subsequent page or to go into a power saving sleep mode.

摘要： Frames of information are communicated between a base station (28) of a radio access network (RAN) and plural types of wireless terminals (30). Frame handlers of the base station and of certain types of wireless terminals (30-2) process differing portions of the frame according to respective differing multiple access technologies.

摘要： The iterative decoding of blocks may be continued or terminated based on CRC checks. In an example embodiment, one iteration of an iterative decoding process is performed on a block whose information bits are covered by a CRC. The iterative decoding process is stopped if the CRC checks for a predetermined number of consecutive iterations. In another example embodiment, a decoding iteration is performed on a particular sub-block of multiple sub-blocks of a transport block, which includes a single CRC over an entirety of the transport block. The CRC is checked using decoded bits obtained from the decoding iteration on the particular sub-block and decoded bits obtained from previous decoding iterations on other sub-blocks of the multiple sub-blocks. The decoding iteration is then performed on a different sub-block if the CRC does not check. Also, the decoding iterations for the sub-blocks may be terminated if the CRC checks.

摘要： According to methods and apparatus taught herein, an Orthogonal Frequency Division Multiplexed (OFDM) transmitter increases pilot density in the edge regions of an OFDM signal, such as by using additional pilot sub carriers in the edge regions. For example, the OFDM signal includes first pilot sub carriers uniformly distributed across the frequency band of the OFDM signal, and second pilot sub carriers distributed within the edge regions. A corresponding OFDM receiver circuit uses the increased pilot density to improve channel estimation. For example, the receiver circuit uses the first pilot sub carriers in a Maximum Likelihood (ML) estimation process to obtain first channel estimates, and uses the results of ML estimation along with the second pilot sub carriers in a Minimum Mean Square Error (MMSE) estimation process to obtain second channel estimates. The receiver forms the improved channel estimates using the first and second channel estimates.

摘要： Code words are assigned to subscriber stations or groups of subscriber stations in a communication network for a quick paging mechanism in which the assigned code words are transmitted as quick paging signals over unused frequency resources to signal the subscriber stations. Subsets of multiple code words from a set of code words can be assigned to respective paging groups, and overlapping subsets can be assigned to multiple paging groups. This enables a single code word to be used to address either a single paging group or multiple paging groups.

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.
