摘要： A method and apparatus for physically secure communication over machine-to-machine (M2M) networks is claimed, through the use of frequency-hop and random access spread spectrum modulation formats employing using truly random spreading codes and time/frequency hopping and receiver selection strategies at the transmitters in the M2M network, blind signal detection and linear signal separation techniques at the receivers in the M2M network, completely eliminating the ability for an adversary to predict and override M2M transmissions. Additional physical security protocols are also introduced that allow the network to easily detect and identify spoofing transmissions on uplinks and downlinks, and to automatically excise those transmissions as part of the despreading procedure, even if those transmissions are received at a much higher power level than the intended transmissions. Extensions to weakly and strongly macrodiverse networks are also described, which provide additional efficiency and security improvements by exploiting the route diversity of the network.

摘要： A method and apparatus may include receiving, by a machine type communication user equipment, parameters for frequency hopping in downlink or uplink. The parameters comprise an “X,” ‘Y,” and “Z” parameters, “X” corresponds to a duration for which the same physical resource blocks are used for transmission. ‘Y” corresponds to a frequency hopping period, and “Z” corresponds to a frequency hopping pattern indication. The method may also include performing frequency hopping in accordance with the parameters.

摘要： Apparatus and methods for time division multiplexing of radio frequency channels in unlicensed radio frequency bands by a wireless device in communication with a cellular wireless network are disclosed. The wireless device obtains, from an eNodeB, a configuration for carrier aggregation using a primary component carrier (PCC) in a licensed radio frequency band and at least one secondary component carrier (SCC) in an unlicensed radio frequency band. The configuration information specifies an “on” time period and an “off” time period for a repetitive time division cycle to use the at least one SCC in the unlicensed radio frequency band. During an “on” time period, the wireless device can transmit or receive using the PCC and the at least one SCC, as scheduled by the eNodeB. During an “off” time period, the wireless device can transmit or receive using the PCC and not using the at least one SCC.

摘要： Methods and apparatuses are provided for transmitting data in a subframe including two slots in a communication system. Resource allocation information is received at a UE. The UE determines a resource for data transmission based on the resource allocation information, whether hopping is enabled, whether mirroring is enabled, and whether hopping is intra-subframe and inter-subframe hopping or inter-subframe hopping. Data is transmitted via the determined resource from the UE to a Node B.

摘要： A semiconductor integrated circuit for a radio communication terminal sequentially uses a plurality of frequency channels by instructions from a hopping frequency decision unit to receive packet data by a reception unit. When the integrated circuit cannot detect the head of the packet data in reception operations, the integrated circuit cannot receive packet data should be received originally then assumes that the received packet data is a packet error. And the integrated circuit calculates packet error rates for each frequency channel on the basis of the number of times of reception operations performed for each frequency channel and of the number of times of packet errors to estimate channel qualities by using the packet error rates.
