Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may transmit, to a user equipment (UE), an indication of a multi-level coding scheme that specifies a first encoding algorithm associated with level 1 coding and a second encoding algorithm associated with level 2 coding based at least in part on power management. The network entity may communicate with the UE based at least in part on the multi-level coding scheme. Numerous other aspects are described.

A base station may make more efficient use of resources by transmitting data in a control region of a slot in addition to a data region. In order to avoid performance loss, the base station may adjust the data transmission in the control region in comparison to a data transmission in a data region and may signal an indication to a UE to assist the UE in receiving the data transmission in the control region. An apparatus for wireless communication at the UE receives the indication from the base station regarding the data transmission in the control region and uses the indication to perform rate matching or demodulation of the data transmission in the control region. The indication may indicate any of a different MCS/rank/TPR, a reduced MCS/rank/TPR, an MCS/rank/TPR delta, a control span for a group of UEs, and a starting symbol for the data transmission. The indication may also indicate that there is no data transmitted on resources in the control region.

Multiplexed unequal error protection for wireless networks is disclosed. A device may determine reliability associated with a first subcarrier of a channel including the first subcarrier and at least one second subcarrier. The reliability of the first subcarrier may be determined based on the position of the first subcarrier relative to each at least one second subcarrier. High priority data may be assigned to the first subcarrier for transmission if the first subcarrier is determined to have a higher reliability than the at least one second subcarrier. For example, the channel may be an orthogonal frequency division multiplexed (OFDM) channel and higher reliability may be associated with a first subcarrier that is in a middle position of the plurality of subcarriers within the OFDM channel. In another example, higher reliability may be associated with a first OFDM subcarrier that is adjacent to an unused OFDM channel bandwidth.

Embodiments of the present invention relate to a data transmission method and apparatus based on unequal error protection and a device. The method includes: segmenting, according to a quantity of symbol bits in a constellation diagram, a code block corresponding to data, to obtain segmented code blocks; performing rate matching on the segmented code blocks obtained by channel encoding, to obtain output code blocks; cascading the output code blocks according to the quantity of symbol bits in the constellation diagram, to obtain cascaded code blocks; and sending the cascaded code blocks to a terminal device.

A system and method for transmitting data over a channel, in which the data are categorized in at least two different categories. For example, the data are categorized according to the effect on perceived degradation on the data when error mitigation is performed on the data. Corrupted data of the first category are replaced using a first replacement method, such as retransmission and forward error correction. The corrupted data of the second category are replaced using a second replacement method different from the first replacement method, e.g., error mitigation or interpolation.

A wireless communication device includes a communication interface and a processor that operate to generate a first transmission stream by processing first information based on first parameter(s) and a second transmission stream by processing second information based on second parameter(s). In some examples, the second at least one parameter is relatively less robust than the first at least one parameter, and the second information augments the first information when combined with the first information. The wireless communication device then transmits the first transmission stream and the second transmission stream to at least one other wireless communication device. Examples of such parameters include forward error correction (FEC) code, error correction code (ECC), modulation coding set (MCS), modulation type including a mapping of constellation points arranged in a constellation, power (e.g., transmit (TX) power), orthogonal frequency division multiplexing (OFDM) configuration, and/or a multiple-input-multiple-output (MIMO) configuration.

A method for modulating and coding a data packet comprising digitally encoded information. The method comprises selecting a hierarchy of modulation and coding schemes to use for modulation and coding of the digitally encoded information. The method also comprises identifying, among the bits in the digitally encoded information and based on the selected hierarchy of modulation and coding schemes, two sets of data, a first set of data and a second set of data, the second set of data being a sub-set of the first set of data and comprising bits different from the most robust bits of the first set of data. The method further comprises performing modulation and coding of the first set of data using a modulation and coding scheme with high order modulation in order to create a first layer of the data packet.

A method of auto-detection of WLAN packets includes selecting a first Golay sequence from a first pair of Golay complementary sequences associated with first packet type, each Golay sequence of the first pair of Golay complementary sequences being zero correlation zone (ZCZ) sequences with each Golay sequence of a second pair of Golay complementary sequences associated with a second packet type, and transmitting a wireless packet carrying a short training field (STF) that includes one or more instances of the first Golay sequence.

A wireless communication device includes a communication interface and a processor that operate to generate a first transmission stream by processing first information based on first parameter(s) and a second transmission stream by processing second information based on second parameter(s). In some examples, the second at least one parameter is relatively less robust than the first at least one parameter, and the second information augments the first information when combined with the first information. The wireless communication device then transmits the first transmission stream and the second transmission stream to at least one other wireless communication device. Examples of such parameters include forward error correction (FEC) code, error correction code (ECC), modulation coding set (MCS), modulation type including a mapping of constellation points arranged in a constellation, power (e.g., transmit (TX) power), orthogonal frequency division multiplexing (OFDM) configuration, and/or a multiple-input-multiple-output (MIMO) configuration.

A radio transmitting device and method enables reduction of an increase of CGI memories for the control channel and an improvement of the throughput of the data channel. When multiplex transmission through the control channel and the data channel is carried out and when adaptive modulation is applied to both channels, an MCS selecting section is provided with one CQI table for the data channel and CQI tables for the control channel, and a table selecting MCS determining section selects one of the tables depending on the transmission bandwidth of the terminal and determines the MCS of the control channel while looking up the selected CQI table.
