Certain aspects of the present disclosure provide techniques for link configuration-specific modulation and coding scheme (MCS). A method that may be performed by a user equipment (UE) includes receiving control information indicating an MCS index corresponding to one or more MCS parameters to be used for a communication link, determining the one or more MCS parameters corresponding to the MCS index, wherein a mapping of the MCS index to the one or more MCS parameters is dependent on a configuration of the communication link, and communicating via the communication link in accordance with the one or more MCS parameters.

Provided are a data communication processing method and device. The method includes: acquiring a modulation order and a target code rate; calculating an intermediate number N.sub.info of information bits at least according to a total number of resource elements, the modulation order and the target code rate; quantizing the intermediate number N.sub.info of the information bits to obtain the quantized intermediate number N′.sub.info; determining a transport block size (TBS) according to the quantized intermediate number N′.sub.info.

Introduced here are approaches to classifying traffic that comprises data packets. For each data packet, a classification engine implemented on a computing device can identify an appropriate class from amongst multiple classes using a lookup table implemented in a memory. The memory could be, for example, static random-access memory (SRAM) as further discussed below. Moreover, the classification engine may associate an identifier with each data packet that specifies the class into which the data packet has been assigned. For example, each data packet could have an identifier appended thereto (e.g., in the form of metadata). Then, the data packets can be placed into queues based on the identifiers. Each queue may be associated with a different identifier (and thus a different class).

A terminal includes a transmission unit configured to transmit control information including an index indicating an MCS (Modulation and Coding Scheme) to another terminal; and a control unit configured to include the index that is reserved, in the control information, in a case of indicating, to said another terminal, information defined in advance.

Provided in some implementations is a sidelink-related operation method of a first user equipment (UE) in a wireless communication system, including the steps in which: a first UE receives, from a second UE, a physical sidelink control channel (PSCCH) including modulation coding scheme (MCS) information; a channel status information reference signal (CSI-RS) and a physical sidelink shared channel (PSSCH) related to the PSCCH are received; CSI is derived on the basis of the CSI-RS; and the first UE transmits, to the second UE, a CSI report including the CSI, wherein the CSI is derived on the basis of the determination of an MCS table.

Methods, systems, and devices for wireless communications are described. A transmitting device such as a base station and a user equipment (UE), may segment a set of bits within a transport block into a first subset of bits including modulation bits and a second subset of bits including index modulation bits. The transmitting device may map the first subset of bits to a first set of subcarriers, the second subset of bits to a second set of subcarriers, and an additional set of bits to a third set of subcarriers. The transmitting device may generate a signal according to a boosting factor based on mapping the first subset of bits, the second subset of bits, and the additional set of bits, and transmit the generated signal to a receiving device.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling that may identify a configuration for channel state information reporting associated with both a first target block error rate and a second target block error rate. The UE may receive one or more reference signals associated with the channel state information reporting. Further, the UE may transmit, to the base station, the channel state information reporting that may include first channel state information for the first target block error rate and second channel state information for the second target block error rate. In some examples, each of the first channel state information and the second channel state information may be based on the received reference signals.

A transmission processing method includes: coding a transmission bit in an available coding scheme; and sending coded information, where the available coding scheme includes at least one of: performing joint source-channel coding at a physical layer; performing channel coding with a code rate greater than one at the physical layer; performing joint source-channel coding with a code rate greater than one at the physical layer; performing channel coding at the physical layer by directly using an input bit as an output bit; performing channel coding at the physical layer, the channel coding including at least the following two parts: a CRC part and a part directly using an input bit as an output bit; and using joint channel-source coding at a non-physical layer.

A method is performed by a wireless communications device of transmitting measurement reports to an infrastructure equipment. The method comprises receiving signals transmitted by the infrastructure equipment, measuring a characteristic associated with the received signals, and selecting an index value from one of a plurality of index values. Each of the index values represents a range of values of the characteristic for which communications parameters of a transmitter in the infrastructure equipment and a receiver in the communication device should have to achieve an acceptable communications performance for values of the characteristic within the range of values of the characteristic. The method further comprises, subject to the selected index value, transmitting the selected index value to the infrastructure equipment.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station and in a first slot, an indication of a signal to noise ratio (SNR) mode, of a plurality of SNR modes, to be used by the UE for one or more downlink communications in one or more slots that occur after the first slot, wherein different SNR modes of the plurality of SNR modes support at least one of different modulation and coding schemes, different ranks, or a combination thereof; and operate using the SNR mode in the one or more slots based at least in part on the indication. Numerous other aspects are provided.
