Certain aspects of the present disclosure propose techniques for transmission time interval (TTI) bundling for physical downlink shared channel (PDSCH) in long term evolution (LTE). According to certain aspects a method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH) and receiving the data on the PDSCH in the susbset of subframes.

The present implementations relate to codeblock concatenation for improved vulnerable symbol handling. For example, a transmitter user equipment (UE) may, for each of the first codeblock and the second codeblock, a first number of coded bits to be mapped to the first number of resource elements satisfying a vulnerability condition and the second number of resource elements not satisfying a vulnerability condition. The UE further extracts, for each of the first codeblock and the second codeblock, a subset of the first number of coded bits and a subset of the second number of coded bits. The UE further concatenates the subset of the first and second number of coded bits from the first codeblock and the second codeblock, and generates a concatenated codeblock for transmission including the concatenated subset of the first number of coded bits and the concatenated subset of the second number of coded bits.

A communication device, method, and data transmission system are provided. An illustrative method is disclosed to include at least one data port and lossless IPG circuitry that operates on the transmit-side and/or receive-side of the data transmission system. The lossless IPG circuitry may include a lossless IPG insertion circuit and/or a lossless IPG removal circuit that work in cooperation with each other to ensure that data streams do not violate any predefined communication protocols or requirements thereof.

A transceiver associated with a wireline communication system is disclosed. The transceiver comprises one or more processors configured to associate a quality of service (QoS) grade tag to each data packet of a plurality of data packets to be transmitted and assemble a data transfer unit (DTU) comprising one or more or a part of a data packet of the plurality of data packets, wherein the one or more or the part of the data packet are encapsulated into a plurality of DTU frames within the DTU. The one or more processors is further configured to associate a highest DTU tag to the assembled DTU, wherein the highest DTU tag is indicative of a highest QoS grade associated with the DTU frames of the assembled DTU; and determine a schedule for transmission or retransmission of the assembled DTU, based on the highest DTU tag of the assembled DTU.

The described technology is generally directed towards adaptively changing which transmission scheme a user equipment is to use based on a Doppler metric (e.g. Doppler frequency) as evaluated against a threshold Doppler value. A network instructs a user equipment to use a Rank-1 precoder cycling transmission scheme if the Doppler metric of user equipment is above a threshold value, or to use a closed loop MIMO transmission scheme if the user equipment has a Doppler metric below the threshold value. The network can instruct the user equipment via a suitable message, or by switching off TPMI and notifying the user equipment thereof.

Techniques are provided for reduction of processing requirements for portions of a received transmission relative to processing requirements for other portions of the same transmission. Different coding schemes may be employed for portions of a data transmission. In some examples, a tail portion of a data transmission may use a coding scheme that had reduced processing requirements relative to other portions of the data transmission. The reduced processing requirements may allow a receiver to generate an acknowledgment of receipt relatively quickly, which may reduce latency for acknowledging receipt of a transmission.

Disclosed is an electronic device including a speaker, a communication circuit, a processor, and a memory. The processor is configured to receive first data including a first audio frame corresponding to a first interval and a second audio frame corresponding to a second interval subsequent to the first interval, using the communication circuit, to store the second audio frame in the memory in response to reception of the first data, to output a first audio signal generated based on the first audio frame, through the speaker, and to store the third audio frame in the memory and output a second audio signal generated based on the second audio frame of the second data through the speaker when second data including the second audio frame and a third audio frame corresponding to a third interval subsequent to the second interval is received using the communication circuit.

The present invention provides a method of transmitting broadcast signals. The method includes, encoding, by an encoder, PLP (Physical Layer Pipe) data; time interleaving, by a time interleaver, the encoded PLP data; frame mapping, by a framer, the time interleaved PLP data onto at least one signal frames; frequency interleaving, by a frequency interleaver, data in the at least one signal frames; and waveform modulating, by a waveform module, the frequency interleaved data in the at least one signal frame and transmitting, by the waveform module, broadcast signals having the modulated data, wherein the frequency interleaving is conducted according to an interleaving mode, wherein the interleaving mode is determined based on a FFT (Fast Fourier Transform) size.

A method for communication, including, in a Physical Layer (PHY) transceiver, selecting a transmission bitrate from a plurality of transmission bitrates, for transmitting over a media interface bits received from an external device. The received bits are processed by generating, using a framing and encoding scheme that depends on at least the selected transmission bitrate, frames having a common frame length among the framing and encoding schemes. The frames are encoded to produce code words of a predefined Forward Error Correction Code (FEC) code, using a single FEC encoder that accepts a number of bits for encoding equal to the frame length. Sub-units of the code words are mapped into symbols using one of at least two mapping schemes that employ different voltage amplitude levels to define a transmission symbol, the mapping scheme being selected according to the selected transmission bitrate. The symbols are transmitted over the media interface.
