A method of communication in a vehicle network is provided. An example method includes transmitting a network allocation map in a TDMA cycle, indicating reservation of time slots in the TDMA cycle. The method further includes transmitting a synchronization signal in the TDMA cycle, to synchronize the timing of nodes in the vehicle network. Each of the reserved time slots is identified by at least a network ID of a transmitting node in the vehicle network, and a slot type comprising one of a low latency traffic slot, and a bulk traffic slot. Further, the low latency traffic slots are repeated in the TDMA cycle at least as frequently as a guaranteed QoS latency parameter. Further, the bulk traffic slots are at least as long as a guaranteed QoS throughput parameter.

On-demand allocation of communication capacity in a Mobile ad hoc Network (MANET) involves initiating in a first node of the MANET, a request for network communication capacity. The request is initiated by wirelessly transmitting an access request in a first epoch, during an access request time slot of a TDMA waveform. The access request is directed to one-hop neighbor nodes with which the first node can communicate directly. The first node determines whether the access request has been granted based on one or more responses received from the one-hop neighbor nodes. These responses include an indication by each of the one-hop neighbor nodes regarding their availability to accommodate the access request. The first node subsequently uses network communication capacity granted to it for communicating data.

Methods, systems, and devices are described for low latency communications within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system and may send triggers to initiate communications using a dedicated resource in a wireless communications network that supports transmissions having a first subframe type and a second subframe type, the first subframe type comprising symbols of a first duration and the second subframe type comprising symbols of a second duration that is shorter than the first duration. Communications may be initiated by transmitting a trigger from the UE or eNB using the dedicated resource, and initiating communications following the trigger. The duration of time between the trigger and initiating communications can be significantly shorter than the time to initiate communications using legacy LTE communications.

A system comprises a computer having a processor and a memory, the memory storing instructions executable by the processor to identify data to be communicated to a satellite gateway via a satellite, the data including first data and second data, determine to communicate the data to the satellite gateway in a time-division multiplexing (TDM) and time-division multiple access (TDMA) (TDM/TDMA) concurrent transmission mode, and responsive to the determination to communicate the data to the satellite gateway in the TDM/TDMA concurrent transmission mode, transmit the first data to the satellite according to a TDM channel access scheme and transmit the second data to the satellite according to a TDMA channel access scheme that differs from the TDM channel access scheme.

The present disclosure provides a downlink data transmission method, including: using a time-division multiplexing transmission mode in one transmission time interval; sending, by using a wide beam, a control signal to a user served in the current transmission time interval; and grouping users and sending data signals to different user groups by using different narrow beams. In one transmission time interval, time-division multiplexing is used, and a wide beam and a narrow beam are respectively used to transmit a control signal and a data signal. This can avoid a throughput bottleneck resulting from use of a transmission scheme that is based on frequency-division multiplexing only.

A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.
