Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for determining a set of communication parameters for receiving data transmissions. In some implementations, a method includes receiving a first data transmission sent according to a first communication parameter scheme that includes at least one of a first modulation or a first coding. A second data transmission is received. A second communication parameter scheme of the second transmission is determined. This determination includes identifying a subset of multiple candidate communication parameter schemes determined based on the first communication parameter scheme, identifying, in the second data transmission, a first identifier that corresponds to the second communication parameter scheme, comparing the first identifier to a respective identifier for each communication parameter scheme in the subset, and determining, as the second communication parameter scheme, a communication parameter scheme in the subset that has an identifier that matches the first identifier.

This application relates to the field of communications technologies, and discloses a method and an apparatus for indicating a number of repetitions, so that a configuration of a number of repetitions of an SRS and/or a PUSCH is more adaptive to a channel change. The method includes: A network device sends DCI to a terminal device, where the DCI includes first indication information, and the first indication information indicates a number of repetitions of an SRS and/or a PUSCH. Because the DCI has a faster update process than RRC signaling, and overheads are smaller than those of the RRC signaling, the network side device may flexibly configure the number of repetitions of the SRS and/or the PUSCH by using the DCI, to better adapt to the channel change, and further improve a channel estimation capability and signal demodulation performance.

A method to operate a transmitting radio device of a radio communications network is provided, wherein the method comprises: transmitting, to a receiving radio device, first data according to a first transmit mode; determining a first transmit mode time period of the first transmit mode so that the first transmit mode time period does not exceed a survival time period of the transmitting radio device; determining a last reception time when an acknowledgment was received from the receiving radio device, wherein the acknowledgement indicates a successful reception of the transmitted first data at the side of the receiving radio device; and transmitting, to the receiving radio device, second data according to a second transmit mode, wherein the second transmit mode is activated upon expiry of the first transmit mode time period since the determined last reception time.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station transmitting a modulation and coding scheme index corresponding to a modulation and coding scheme table to a user equipment (UE). The modulation and coding scheme index may be applied to encoding or decoding a transport block. The modulation and coding scheme may be associated with at least two modulation orders or a differential indication according to a modulation and coding scheme table. To determine which of the modulation orders for processing the transport block, the UE and the base station may use a prior modulation order associated with a prior transmission of the transport block. The UE may process the transport block by encoding or decoding the transport block based at least in part on the determined modulation order.

Methods, a network node, a wireless device, and computer readable storage medium for 16-QAM based communication are disclosed. A method includes: determining a resource allocation for 16-QAM based communication for the wireless device; and indicating, to the wireless device, a TBS and/or a number of allocated time-domain resources that are associated with the determined resource allocation using a TBS index and a time-domain resource index, wherein the TBS index and the time-domain resource index are determined in accordance with a table for allocating transport blocks and/or number of allocated time-domain resources for the 16-QAM based communication.

Device-to-device (D2D) transmissions by a wireless device may interfere with base station reception of other signals. To mitigate this interference, the wireless device estimates the path loss between itself and the base station. The path loss and the current D2D transmission power level are used to estimate the amount of interference the base station is experiencing as a result of the D2D transmissions from the wireless device. Based on the estimated interference experienced by the base station, the wireless device increases the robustness of the MCS being used and decreases the transmission power level by a corresponding amount. By decreasing the D2D transmission power level, less interference will be experienced by the base station. By increasing the robustness of the MCS, the impact of the reduced D2D transmission power level is mitigated.

Methods, systems, and devices for wireless communication are described that support communication of information buts based on reference signal index modulation (RS-IM). A base station and a UE may transmit a number of downlink and uplink information bits (e.g., downlink control bits, uplink control bits) using index modulation schemes applied on references signals. A base station and a UE may transmit reference signal transmissions using reference signal index modulation, in which a set of information bits may be encoded using one or more coding techniques, in conjunction with RS-IM techniques, to enhance reliability of some or all of the information bits. Error detection bits may be added to the information bits, and included when coding is performed. Coding may include channel coding, repetition of reference signals for combining at a receiving device, or any combinations thereof.

Artificial Intelligence (AI) means are disclosed for enabling network operators to optimize 5G and 6G messaging performance, in real-time. AI models, or fieldable algorithms derived therefrom, can select an appropriate modulation scheme according to network conditions. Modulation variables can then be adjusted to optimize performance, such as throughput or failure rates, for low or high traffic densities. Three development phases are described: network data acquisition including faults experienced under various network conditions, AI structure tuning for accurate prediction of performance, and implementation of a fieldable algorithm based on the AI structure. Network operators can use the fieldable algorithm to compare predicted performance metrics in real-time, according to various operating conditions (such as available modulation schemes), and thereby adjust particular modulation parameters (such as amplitude or phase levels).
