Aspects of the disclosure relate to repeater controlled by a base station. The repeater receives control signaling including control information in association with traffic relayed through the repeater, between a first wireless communication device and a second wireless communication device, the repeater obtains a time division duplex state from the control information, obtains a fronthaul-link transmission control indicator (TCI) state index from the control information, obtains an access-link TCI state index from the control information, obtains a time domain resource allocation from the control information, and configures a relay unit of the repeater to communicate the traffic between the first wireless communication device and the second wireless communication device based the control information comprising at least one of: the time division duplex state, the fronthaul-link TCI state index, the access-link TCI state index, and the time domain resource allocation. The base station sends the control signaling to control the repeater.

Example channel state information (CSI) transmitting methods and apparatus are described. The CSI is a part of uplink control information (UCI) and it includes a first quantity of bits. One example method includes determining a threshold code rate according to a modulation and coding scheme (MCS) index when the CSI is to be transmitted on a physical uplink shared channel (PUSCH) without uplink data. A second quantity of bits is determined according to the threshold code rate and the first quantity of bits, where the second quantity of bits is less than or equal to the first quantity of bits. The second quantity of bits of the CSI is transmitted on the PUSCH.

Aspects relate to wireless communication using multiple active bandwidth parts (BWPs). For example, a base station may configure a user equipment (UE) with two or more active BWPs. In some examples, the base station may send scheduling information to the UE on one active BWP, where the scheduling information schedules a communication on one or more active BWPs.

A method of wireless communication may include monitoring, by a first device, a medium for frames in response to preparing to transmit a first frame to a second device. The method may also include while monitoring the medium and before transmitting the first frame, obtaining a second frame transmitted by a third device in the medium and adjusting a transmission of the first frame to the second device in the medium based on obtaining the second frame.

This application discloses a method for sending a demodulation reference signal, a method for receiving a demodulation reference signal, and a communication apparatus. The method for sending a demodulation reference signal includes: A network device generates a first signal and sends the first signal on a first time-frequency resource, where the first signal is formed by superimposing M DMRS port signals, and delay segmentation locations corresponding to at least two of the M DMRS port signals are different. Because the first signal is formed by superposing the M DMRS port signals, that is, the network device sends a plurality of DMRS port signals on a same time-frequency resource, reference signal overheads can be reduced. The network device sends more DMRS port signals on the same time-frequency resource. In this way, the network device can send more streams without increasing pilot overheads.

A base station can prevent deterioration of data channel application control accuracy due to influence of transmission power control to a control channel. In the base station, each encoding section performs encoding processing to an SCCH (Shared Control Channel) of each mobile station, each modulating section performs modulation processing to the encoded SCCH, an arranging section arranges the SCCH to each mobile station to one of a plurality of subcarriers which configure an OFDM symbol, and transmission power control section controls transmission power of the SCCH based on reception quality information reported from each mobile station. The arranging section arranges a plurality of the SCCH to be under transmission power control to one of the subcarriers so that combinations at resource blocks are the same.
