Techniques are disclosed relating to spectrum sharing between different radio access technologies. In some embodiments, a broadcast base station is configured to wirelessly broadcast audio and video data to a plurality of broadcast receiver devices using a particular frequency band. In these embodiments, the broadcast base station is configured to discontinue broadcasting in the particular frequency band during a scheduled time interval, to enable one or more cellular base stations to perform cellular packet-switched wireless data communications using the particular frequency band.

Shared spectrum access for broadcast and bi-directional, packet-switched communications

An extensible communication system is described herein. The system includes a first module for receiving a root index value and for generating a constant amplitude zero auto-correlation sequence based on the root value. The system further includes a second module for receiving a seed value and for generating a Pseudo-Noise sequence based on the seed value. The system further includes a third module for modulating the constant amplitude zero auto-correlation sequence by the Pseudo-Noise sequence and for generating a complex sequence. The system further includes a fourth module for translating the complex sequence to a time domain sequence, wherein the fourth module applies a cyclic shift to the time domain sequence to obtain a shifted time domain sequence.

System discovery and signaling

An example method of mapping a plurality of modulation symbols of a plurality of physical layer pipes present in a frame to a resource grid of data cells for the frame is described. The modulation symbols of the plurality of physical layer pipes are represented by a two-dimensional array comprising the modulation symbol values for the plurality of physical layer pipes and the resource grid of data cells is represented by a one-dimensional sequentially indexed array.

Advanced data cell resource mapping

A method performed by user equipment (UE) includes receiving a request to access a service unavailable through a first network cell associated with the UE, and receiving a message from an access device associated with the first network cell, wherein the message identifies a plurality of second network cells providing the service.

Method for accessing a service unavailable through a network cell

A method for operating a transmitting device to communicate with a receiving device is described herein. The method includes the step of the transmitting device selecting a root index value from a set of root index values. The method further includes the step of the transmitting device generating a frequency domain Constant Amplitude Zero Auto-Correlation sequence based on the selected root index value. The method further includes the step of the transmitting device modulating the Constant Amplitude Zero Auto-Correlation sequence by a pseudo-noise sequence. The method further includes the step of the transmitting device generating an Orthogonal Frequency Division Multiplexing symbol, wherein the frequency domain Constant Amplitude Zero Auto-Correlation sequence modulated by the pseudo-noise sequence defines subcarrier values for the Orthogonal Frequency Division Multiplexing symbol. The method further includes the step of the transmitting device transmitting the Orthogonal Frequency Division Multiplexing symbol as an initial Orthogonal Frequency Division Multiplexing symbol of a preamble of a frame to the receiving device.

Dynamic configuration of a flexible orthogonal frequency division multiplexing PHY transport data frame preamble

A base station may generate and transmit a transport stream including a sequence of frames. A frame may include a plurality of partitions, where each partition includes a corresponding set of OFDM symbols. For each partition, the OFDM symbols in that partition may have a corresponding cyclic prefix size and a corresponding FFT size, allowing different partitions to be targeted for different collections of user devices, e.g., user devices having different expected values of maximum delay spread and/or different ranges of mobility. The base station may also dynamically re-configure the sample rate of each frame, allowing further resolution in control of subcarrier spacing. By allowing the cyclic prefixes of different OFDM symbols to have different lengths, it is feasible to construct a frame that confirms to a set payload duration and has arbitrary values of cyclic prefix size per partition and FFT size per partition. The partitions may be multiplexed in time and/or frequency.

Dynamic configuration of a flexible orthogonal frequency division multiplexing PHY transport data frame

Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different target geographic areas. A data frame may include a first partition that includes a physical layer encoding of first data to be transmitted in a first geographic area, where the first geographic area is defined by a first threshold distance from the one or more transmitters. The data frame may include a second that includes a physical layer encoding of second data to be transmitted in a second geographic area, where the second geographic area is defined by a second, greater threshold distance from the one or more transmitters.

Multi-portion radio transmissions

Methods and devices are described for polar encoding and decoding control information that has been modulated based on one or more identifiers of the transmitter and/or receiver. Some embodiments describe scrambling sequence design for multi-mode block discrimination on control information blind detection and decoding. Separate scrambling masks may be applied to disparate bit fields within a coded DCI message, wherein each of the scrambling masks is derived from a user equipment (UE)-specific identifier, a UE group identifier, or a base station identifier. Frozen bits of the polar code may be used to encode and transmit hybrid automatic repeat request (HARQ) acknowledgment messaging for early retransmission of unsuccessful downlink messages. A tiered process of UE identification may be employed to improve a balance between early termination of the decoding process and success of the UE identification process.

Scrambling sequence design for multi-mode block discrimination on DCI blind detection

Techniques are disclosed relating to generating and receiving radio frames with multiple portions that have different encoding schemes. An apparatus may include one or more processing elements configured to receive, via a wireless radio, wireless data that includes a plurality of portions that each include multiple orthogonal frequency-division multiplexing (OFDM) symbols. Different ones of the portions have different frequency transform sizes and different sampling rates. The wireless data may also include control data that indicates the frequency transform sizes and sampling rates for the ones of the portions. The apparatus may select, based on the control data and a determined velocity of the apparatus, one or more but not all of the plurality of portions and may decode the selected one or more portions to determine data represented by the OFDM symbols in the selected one or more portions. Different portions of the wireless data may be adapted for decoding by devices moving at different maximum velocities.
