摘要： Systems and methods for transmitting uplink control signals in a cellular communications network are disclosed. In one embodiment, a wireless device configured to operate in a cellular communications network includes a radio subsystem and a processing subsystem. The processing subsystem selects a value for at least one parameter for an uplink control channel format based on content to be transmitted in an uplink control channel transmission according to the uplink control channel format. The processing subsystem then transmits, via the radio subsystem, the content in an uplink control channel transmission according to the uplink control channel format and the value for the at least one parameter for the uplink control channel format selected based on the content.

摘要： Systems and method are disclosed for graph-based distributed parameter coordination in a communication network. In general, discrete local parameters to be coordinated among communication nodes in the network and their respective performance metrics, or costs, are modeled using a factor graph. Based on the factor graph, a variant of the sum-product algorithm, namely the min-sum algorithm, is applied in order for the communication nodes, through iterative message passing with their neighboring communication nodes, to decide upon optimal values for the local parameters for the communication nodes that collectively optimize a global performance metric across the communication network. Tn one embodiment, the communication network is a wireless communication network. In one specific embodiment, the wireless communication network is a cellular communication network.

摘要： A system and method to perform Full Duplex, FD, Space Division Duplex, SDD, communication using a Self- Interference Cancelling, SIC, precoder (110) that applies different antenna phase shifts and amplitude scales to the transmitted signals to force them to be in the null space of (he selected receive antennas (83-86). Thus, a wireless communication unit (175, 185) can place nulls at each of its receive antennas digitally at baseband for one or more frequency bands. The SIC precoder (110) may be computed based on the self-interference channel from the transmit chains to the receive chains. Different SIC precoders may be adaptively selected and stored digitally for different frequency bands. Subsequent single or multi-user precode can be applied in concatenation with the SIC precoder to transmit signals to one or more users while receiving signals from one or more users simultaneously over the same frequency band.

摘要： A radio terminal's (10) access to an access network over a radio interface using access resources is controlled to reduce network load. The radio terminal is associated with one of a set of access classes, and the radio terminal's ability to access the access network depends on whether the one access class is permitted to access the access network. The radio terminal receives information from the network about limited access resources and permitted access classes. Radio terminals that are not associated with a permitted access class are prohibited from using the limited access resources. The radio terminal determines a first set of one or more time periods during which one or snore available access resources, permitted for use by the access class of the radio terminal, may be used by the radio terminal to access the radio network. The first set of one or more ti me periods is different from other sets of one or more time periods permitted for use by radio terminal s in other access classes to communicate with the radio network. The radio terminal communicates with the access network using the one or more available access resources during the first set of one or more time periods, thereby reducing a network load.

摘要： A system (10) and method to substantially prevent Denial of Service, DoS, attacks due to Random Access Channel, RACH, overload in cellular wireless networks. Once a mobile handset (12) is identified to cause or contribute significantly to a RACH overload of the cell, the system sends (28) a special System Information Block, SIB, message targeted to that mobile handset and instructing it to redirect its RACH signaling to a separate RACH/PRACH, Physical Random Access Channel, resource or to a small part of the current RACH/PRACH resource. The use of a separate RACH/PRACH resource such as frequency, preamble sequence, and/or radio subframe access slot to "absorb" high volume RACH signaling traffic from a small number of malicious/defective mobile handsets substantially prevents signaling Do S attacks from overloading the regular RACH/PRACH resource in the wireless network (14) and makes it more robust to such attacks.

摘要： A system (50) and method for enhanced support for handling of Closed Subscriber Groups, CSGs, and sharing of Radio Access Network, RAN, for home base stations (56) and other small cells. An enhanced System Information, St, structure (64, 68, 74, 78) indicates multiple CSG IDs and CSG Indications, thereby making it possible to support different CSG IDs and CSG Indications for every Public Land Mobile Network Identity, PLMN-ID, and also to support a PLiVIN-ID with multiple associated CSG IDs and CSG Indications, The enhanced St makes it possible to have different CSG IDs for different operators, to have multiple CSG IDs for one operator, and to selectively use the CSG concept for some PLMNs, but not for all. A network of base stations thus can be effectively shared by multiple operators, leading to better cellular coverage, peak rates, and capacity.
