A diversity mode indicator is set to one diversity mode indicator value of a plurality of diversity mode indicator values. Each diversity indicator value is associated with a respective combination of one or more diversity domains for data repetition. Following that, transmitting or receiving a plurality of repetitions is performed based on the one diversity mode indicator value. For at least one of the diversity mode indicator values, the respective combination of one or more diversity domains for repetition comprises space.

Abstract: A user equipment (UE) may determine that a transmission resource includes a first orthogonal frequency-division multiplexing (OFDM) symbol that is configured as a downlink symbol or as flexible, where the transmission resource is allocated for uplink (UL) transmissions during a time duration, and includes K transmission occasions (TOs). The UE may transmit a first UL transmission in the transmission resource omitting the first OFDM symbol. The first UL transmission includes K repetitions to be transmitted in the respective K TOs, and the K repetitions includes an initial transmission and at least one retransmission of the initial transmission.

Abstract: For coordinated operation of UEs, operation of a UE is to be coordinated with an other UE for communicating with a network device in a wireless communication network. Signaling that indicates a limited-operation configuration is transmitted to and received by the UE, and the UE communicates according to the limited-operation configuration. The limited-operation configuration is for limited communication operations of the UE with the network device, and the limited communication operations are limited relative to a full-operation configuration of the other UE for communications with the network device.

Abstract: A data feedback method is described. The method includes a second terminal sending first feedback information to a first terminal based on a sidelink. The first terminal determines, based on a receiving result of the first terminal for first data and a receiving result that is of the second terminal and that is indicated by the first feedback information, second feedback information that is sent to a network device. In this way, an energy saving requirement of the second terminal is met. Moreover, the described method ensures the network device can also determine receiving results of the first terminal and the second terminal based on the second feedback information, thereby reducing unnecessary operations performed by the network device.

Abstract: Embodiments of the present application pertain to control information for scheduling a transmission resource for downlink and uplink communications between one or more TRP and one or more UE. One Physical Downlink Control Channel (PDCCH) for DL control information transmission is assumed to carry at least one assignment or scheduling information block for at least one Physical Downlink Shared Channel (PDSCH) for DL data transmission or for at least one Physical Uplink Shared Channel (PUSCH) for UL data transmission. Embodiments of the present application provide methods of providing configuration information that can be used by a user equipment (UE) to determine transmission mode for the PDSCH and PUSCH as well as information to determine where to monitor for the PDSCH, PUSCH and PUCCH information.

Abstract: This application provides a UCI sending and receiving method and a communications apparatus. In the method, an association relationship between a PUCCH and a PUSCH is established, so that when resources of the PUSCH and the PUCCH overlap, a terminal device can determine UCI on which PUCCHs can be transmitted by multiplexing the resource of the PUSCH. A network device may receive the UCI on the PUSCH. Because the network device may know in advance which PUCCHs and PUSCHs are sent to the network device, the network device can demodulate and decode a signal on the received PUSCHs, to successfully obtain UCI. The network device can make a proper decision based on the UCI.
