This application provides a communication method and apparatus. The communication method includes: adding a modulation coding scheme whose modulation order is 10 for communication between a network device and a terminal device, to improve communication efficiency of the terminal device in an area with better channel quality, including a central area.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive broadcast information from a base station indicating a numerology or a reference signal (RS) pattern to be used in broadcast or multicast transmissions (e.g., a physical multicast channel (PMCH)). The UE may identify a modulation and coding scheme (MCS) associated with the broadcast or multicast transmission and may determine a transport block size (TBS) based on the MCS and at least one of the numerology or the RS pattern. For instance, a UE may determine TBS for numerologies associated with a single symbol that spans multiple subframes differently from that of other numerologies. Additionally or alternatively, a UE may determine TBS for sparse RS patterns differently from that of other RS patterns. The UE may then perform communication with the base station via the broadcast or multicast transmissions in accordance with the TBS.

A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.

Information indication and determination methods and apparatuses. The information indication method includes: issuing joint indication information based on a mapping relationship between quantity of transmission blocks (TB), and at least one of a resource allocation mode and/or a modulation coding strategy (MCS), in which the joint indication information is configured to indicate quantity of scheduled TBs and at least one of the resource allocation mode and the MCS through indicating the mapping relationship.

Techniques are disclosed relating to improving the reliable of a computing network. A first computing device receives changing states of a data object to send to a second computing device via a network interface. The first computing device sends, to the second computing device, a baseline packet having a complete one of the states of the data object. The first computing device sends, to the second computing device, a sequence of update packets corresponding to the changing states of the data object. An update packet in the sequence includes sufficient information to update a stored state of the data object at the second computing device to a current state of the data object responsive to the stored state being one of two or more previous ones of the states.

A method, a computer-readable medium, and an apparatus are provided for wireless communication comprising repetitions that provide a solution to the problem of identifying and refining a repetition configuration at a transmitter. A transmitter receives repetition configuration information from a receiver and transmits repetitions of a signal to the receiver based on the received repetition configuration information. The repetition configuration information comprises an indication of at least one of a repetition frequency hopping indicator, at least one beam index, a repetition type or whether repetition is enabled.

Methods, systems, and devices for wireless communications are described. One method may include a user equipment (UE) determining whether it is configured to support a modulation scheme such as, a quadrature-amplitude-modulation (QAM). The UE may identify a plurality of transport block size (TBS) values based on whether the UE is configured with the modulation scheme, and identify a scaled TBS value that is based on a length of a transmission time interval (TTI). The UE may map the scaled TBS value to a TBS value of a plurality of TBS values (e.g., a plurality of TBS value options). As such, the UE may communicate, with a base station during the TTI, data on a transport block having a size corresponding to the mapped TBS value.

Techniques for wireless communications are described. A user equipment (UE) may be configured with one or multiple transmission and reception points (TRPs). The UE may support sidelink communications, which may be referred to as vehicle-to-everything (V2X) communications systems, vehicle-to-vehicle (V2V) communications systems, and the like. The UE may provide improvements to resource determination for the sidelink communications by determining whether multiple peer UEs can be space-division multiplexed over time and frequency resources. To mitigate interference between the multiple peer UEs, the UE may transmit a power control request message to one or multiple peer UEs to adjust a transmit power level, and a receive a power control response message from the one or multiple peer UEs accepting or rejecting the transmit power level adjustment. As a result, the UE may experience efficient sidelink operations.

Methods, systems, and devices for wireless communications are described. A network node may identify a set of packets for broadcasting to a set of user equipment (UEs) and may transmit a set of encoded packets based on the set of packets. The network node may receive feedback from one or more of the UEs, and the feedback may indicate a number of successfully received packets of the set of encoded packets at each of the one or more UEs. Based on the feedback, the network node may transmit a second set of encoded packets to the set of UEs if the number of successfully received packets for at least one UE fails to satisfy a decodability threshold. The transmitter may continue to transmit sets of encoded packets until the feedback indicates that each UE has received a number of packets that satisfies the decodability threshold.

A method and apparatus, and a storage medium for data transmission are provided. The method may be applied to a terminal. The terminal may receive a Media Access Control (MAC) signaling sent from a base station. The terminal may receive Downlink Control Information (DCI) sent from a base station. The terminal may search in a preset mapping corresponding to n antenna panels for beam indication information corresponding to a beam indication code word as target beam indication information respectively corresponding to the n antenna panels. The terminal may determine, according to the target beam indication information corresponding to a target antenna panel, a corresponding target beam when data transmission is performed by using the target antenna panel. The terminal may perform data transmission with the base station by using the target beam corresponding to the target antenna panel.
