摘要： A multi-pilot frame handler (36) of a radio access network node (28) is arranged to prepare a block of a frame of information to include a first pilot signal of a pilot signal first type and a first pilot signal of a pilot signal second type. The pilot signal of the pilot signal first type is expressed as a first Costas array base pattern of resource elements of the block; the pilot signal of the second type is expressed as a second Costas array base pattern of resource elements of the block. The multi-pilot frame handler (36) is arranged to prepare the block so that any pilot signal of the pilot signal first type is carried by at least some subcarriers of a first set of subcarriers of the block and any pilot signal of the pilot signal second type is carried by at least some subcarriers of a second set of subcarriers of the block.

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： Methods and apparatus by which receiving stations or other communication network nodes can receive quick paging code words assigned by transmitting stations to the receiving stations. A receiving station can estimate the characteristics of the channel to the transmitting station based on a downlink-frame's preamble and use correlation to detect the presence of an assigned code word. The receiving station can suppress interference from other transmitting stations in the correlation operation based on the nature of the interference signal. When the receiving station knows an interfering signal from another transmitting station, the receiving station can subtract the interfering signal before carrying out the correlation operation.

摘要： A system and method of selectively utilizing a feature with an email message. The method includes processing, by a mail client within a user's computer, a single email message for a plurality of recipients. The mail client receives a designated first set of recipients of the plurality of recipients for receiving the email message with a specific feature and a designated second set of recipients of the plurality of recipients for receiving the email message without the specific feature. In addition, a copy of the email message is generated without the specific feature. The email message is then sent with the specified feature to the first set of recipients and a copy of the email message without the specified feature is sent to the second set of recipients. The specific feature may be an attachment, an encryption of the message, or any other feature associated with the email message. In another embodiment, an extension header may be applied to the header of the email message to distinguish the first set of recipients from the second set of recipients. The message may then be sent to an email server which reformats the message into two messages according to the header extensions.

摘要： In a communication system, whether different transmitting stations use the same method or different methods of assigning quick paging code words to receiving stations, the receiving stations in a paging area assume that the same quick paging code words are used by all base stations in the paging area. To enable such operation by the receiving stations in a paging area covered by several base stations, those several base stations share information about the quick paging code words assigned to the various receiving stations known to the base stations.

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： A mobile terminal in a wireless communication network detects congestion and lowers its vocoder source rate in response, to help alleviate the congestion. The mobile terminal may detect the congestion in a variety of ways. The mobile terminal may monitor bandwidth allocation in the network, such as by inspecting the UL-MAP and DL-MAP of an IEEE 802.16 OFDM Physical Layer Frame header, for symmetric allocations. Congestion may be defined by the number of symmetric allocations exceeding a threshold. The congestion threshold may be programmed into the mobile terminal, or may be transmitted by the network. The mobile terminal may infer congestion by being repeatedly granted less bandwidth than requested. The network my explicitly indicate congestion, in a MAC message or by setting a congestion flag in one or more voice data frames. The congestion flag may comprise a reserved encoding of the AMR header Frame Type field.
