摘要： An air time management method for multi-access channel networks is provided, suitable for use when the terminal stations (SS1...SSn) operate with adaptive modulation. A specific modulation (default modulation) is defined for each terminal station (SS1...SSn) in a planning phase. During operation, when bandwidth is to be allotted to an uplink or downlink communication (101), the base station (BS) checks (102) whether the concerned terminal station (SS1...SSn) is operating with a modulation more robust (i. e. less efficient) than the default one. In the affirmative, the base station allots to the communication a time slot whose duration is as needed for transmitting all data with the default modulation (105). In the negative, the base station (BS) allots the communication a time slot whose duration is as needed for transmitting all data with the current modulation (103).

摘要： External packets entering a transmitting entity (SS1...SSn, BS) of a broadband wireless access system are forwarded to a receiving entity onto MAC layer connections (CID1...CID3) at the air interface between such entities in a manner depending on the result of a packet classification (103, 106) performed by using a set of classification rules identified by a rule index and associated with a priority index determining the order of application of different rules to packets relating to a same service. The classification rules (100) include both classification rules specific for data communication protocols and containing one or more protocol-specific parameters to be matched by corresponding fields in a packet being classified, and a pass-through classification rule only containing a priority index and a rule index, but no protocol-specific matching parameter, said pass through classification rule being applied to packet having matched no protocol-specific classification rule.

摘要： Multiple channel response is estimated in MIMO fashion by the radio receivers used in a broadband cellular wireless network, e.g. according to the fixed or mobile WiMAX standardized as IEEE 802.16-2004/e. The transmitted signal includes sequential OFDM modulated symbols carrying data and pilot sequences transmitted on pilot subcarriers diversely allocated in known positions of sequential OFDM symbols. Due to the uncoordinated access, the channel is affected by abrupt variations of the cochannel interference. The channel matrix gathering all unknown elements of the channel response for all K pilot subcarriers on the N R x N T links between the N T transmitting antennas and the N R receiving antennas, is Least Squares (full-rank) estimated at first. The interference covariance matrix is also estimated from the residual. The correlation of the interference covariance matrix is computed at each new symbol and compared with a threshold in order to decide whether the interference is significantly changed or not, to the aim of either re-initialize the interference covariance matrix, in the first event, otherwise updating a running average of the interference covariance matrix with the actual value. Both the update/re-initialized interference covariance matrix and the autocorrelation matrix of the transmitted pilot sequences (stored in the receiver) are used for whitening the estimated channel matrix before submitting it to a modal filtering for the rank reduction. The original spatial and/or temporal correlation's are reintroduced in the reduced-rank channel matrix by inverse whitening. The channel matrix is firstly estimated in the discrete-time domain and then submitted to a DFT for the conversion in the whole frequency band, this allows to be correctly used by the receiver.

摘要： The spacing between adjacent receiving antennas of an ULA located in a base station of a cellular communication system is optimized to both the channel and the interference space-time multipath. The spacing is lager than the canonical λ/2 for introducing a certain degree of angular equivocation aimed to see the interferers (all or a certain number depending on the degree of freedom of the directivity function) as they were grouped together along an unique direction. In an ideal case of fixed interferers with null angular power spread, a given cellular planning and known aperture of the array, the optimal spacing Δ opt between adjacent antennas is directly calculable in closed mathematical form in function of the equal angular separation Δ θ between the DOAs of the interferers. When the restrictive hypotheses are neglected, the optimal spacing Δ opt is calculable as the spacing that minimizes the spread between the N I wave numbers associated to the barycentric DOAs of the N I interfering cells. Moreover closed form solution can be dealt with on condition that N I interfering cells (with one broadside interfering cell) are considered; said angular separation between the interferers is assumed as being the average Δ θ B among adjacent angular separations between barycentric DOAs weighted by the respective barycentric received power. Assuming a multipath channel with an arbitrary number of paths N p , the i th barycentric DOA is calculated by executing a weighted average extended to the N p x S directions of arrival of the N p paths by the S points of a grid indicative of the positions spanned by the i th interfering station inside its cell, weighting each DOA by the power received on that path. In a SIMO scenario with square cell planning according to the fixed or mobile WiMAX IEEE 802.16d802.16-2004/e, the value A opt = 1.8λ is found as an optimum trade-off between beamforming and diversity (fig.5).

摘要： In a packet communication network, a stream of packets is transmissible between two nodes (M, N) over a transmission path therebetween selected out of two transmission paths (A, B) based on a switching decision taken by the receiving node (N) which acts as a decision making node. The decision is taken as a function of one or more quality parameter (BER. throughput, latency). The quality parameter is measured either locally at the decision making node (N) or at another measuring node located in one of the alternative transmission paths (A, B). In this latter case, the quality parameter is transmitted from the measuring node (A1, A2, A3, A4) to the decision node N) thus making it available for the switching decision.

摘要： In a packet communication network, a same stream of packets is transmissible between two nodes (M, N) over a transmission path therebetween including one or more intermediate nodes (A1, A2, B1, B2). In a channel diversity or hot stand-by protection scheme, the transmission path is selected out of different transmission paths (A, B) based on a switching decision taken at a decision node. The transmission path is configured for providing a hop-by-hop check message of the continuity of the transmission path itself. The switching decision is thus taken as a result of one of: an explicit switching command issued by one intermediate node (A1, A2, B1, B2) in the transmission path, and - an implicit switching command implied by the loss of the hop-by-hop continuity check message.
