In a first aspect, a method of wireless communication includes receiving, by a user equipment (UE) from a first network entity, a multiple component carrier (CC) signaling message including multiple CC scheduling information. The method also includes receiving, by the UE from, a downlink control information transmission indicating a downlink control information indication for multiple CCs, and determining a first downlink control information parameter for a first CC and a second downlink control information parameter for a second CC based on the downlink control information indication and the multiple CC scheduling information. The method further includes receiving, from the first network entity, a first downlink transmission for the first CC based on the first downlink control information parameter, and receiving, from a second network entity, a second downlink transmission for the second CC based on the second downlink control information parameter. In other aspects, uplink transmissions may be sent.

A method by a user equipment (UE) is described. The method includes receiving, from a base station, a first radio resource control (RRC) parameter including a first list of one or more CSI trigger states, a second RRC parameter indicating a first total number of bits N_TS1 for a first CSI request field of a first DCI format, a third RRC parameter including a second list of one or more CSI trigger states, and a fourth RRC parameter indicating a second total number of bits N_TS2 for a second CSI request field of a second DCI format, determining a CSI trigger state in response to a CSI request field of a DCI format, wherein in a first case that a total number of the one or more CSI trigger states within the first list is greater than 2.sup.N_TS11, the processing circuitry is further configured to select one or more of the CSI trigger states out of the first list which are mapped to one or more codepoints of the first CSI request field of the first DCI format, in a second case that a total number of the one or more CSI trigger states within the second list is greater than 2.sup.N_TS2−1, the processing circuitry is further configured to select one or more of the CSI trigger states out of the second list which are mapped to one or more codepoints of the second CSI request field of the second DCI format.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating that demodulation reference signal (DMRS) time domain bundling is enabled. The UE may determine a time domain bundling configuration based at least in part on the information indicating that the DMRS time domain bundling is enabled. Accordingly, in some aspects, the UE may perform channel estimation based at least in part on DMRSs received in different physical downlink control channel monitoring occasions based at least in part on the time domain bundling configuration. Numerous other aspects are provided.

A method for transmitting a power headroom, a terminal device, and a network device are provided. The method includes: sending a power headroom PH value of a serving cell to a network device, where the PH value is a first PH value of a first sounding reference signal SRS and/or a second PH value of a second SRS; and the first PH value is obtained based on first configuration information of the first SRS, the first SRS is an SRS used for positioning, and the second SRS is an SRS used for measurement.

Embodiments relate to the field of wireless communication technologies and provide a method for performing channel sounding, a network-side device, and a terminal. A first terminal sends a resource scheduling request to a network-side device when the first terminal starts a communication connection with a second terminal. The resource scheduling request carrying information about the second terminal requests the network-side device to allocate a transmission resource for channel sounding between the first terminal and the second terminal. The first terminal receives a sounding reference signal sent by the second terminal, and obtains information of a channel for communication between the first terminal and the second terminal. The method enables quick and effective channel sounding between terminals, thereby increasing communication efficiency between the terminals.

A wireless communication method includes receiving, by a terminal device, first information sent by a network device. The first information includes a first offset. The first offset is a difference between a frame number of a first system frame and a frame number of a first direct frame. The first system frame and the first direct frame overlap in a time domain. The wireless communication method also includes determining, by the terminal device, the first direct frame based on at least one of the first offset or the frame number of the first system frame.

A sidelink transmission method and apparatus. The method includes: receiving sidelink control information by a terminal equipment at a physical layer (PHY), the sidelink control information being used to trigger report of sidelink channel state information; generating sidelink channel state information by the terminal equipment at the physical layer; and transmitting the sidelink control information and the sidelink channel state information by the terminal equipment from the physical layer to a media access control (MAC) layer. Hence, a valid CSI measurement result may be transmitted, and waste of sidelink resources may be avoided at the same time.

Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may be configured to transmit two or more consecutive transmissions that may be used for demodulation reference signal (DMRS) bundling. If criteria for DMRS bundling are not satisfied, the UE may generate dummy data to transmit during the skipped configured grant occasion, and may maintain phase continuity across the skipped configured grant occasion and any other PUSCHs in a set of uplink transmissions. In some examples, the UE may deprioritize DMRS bundling for sets of PUSCHs during which a PUSCH is to be skipped. If criteria for DMRS bundling are not satisfied, the UE may not maintain phase continuity across the set of PUSCHs, and may refrain from transmitting any data during the CG-PUSCH occasion.

The present disclosure provides radio-frequency (RF) systems that can detect the presence of RF signals received by the system, as well as determine characteristics such as the operating frequency of RF signals, the type of RF source that transmitted each RF signal, and/or the location of each RF source with high precision and sensitivity while using low cost, scalable electronics that are versatile enough for deployment in a variety of environments. Such systems can employ a network of RF sensors that can coordinate in response to communication with a computer to perform any such detection and/or determination using trained models executed onboard the RF sensors and/or the computer. RF signals may have unique characteristics when received at one or more RF sensors that may be detected using trained models described herein, even in high noise or non-line of sight (LOS) environments and with low cost, low resolution RF receiver hardware.

A network device may receive data for multiple wireless channels. The network device may determine an activity level or score for one or more of the wireless channels based on the received data. The network device may determine, based on the activity level for each wireless channel, a portion of the wireless channels that satisfy an activity level threshold. The network device may generate a ranking of the portion of the wireless channels that satisfy the activity level threshold. The ranking may be based on the activity level or score of each wireless channel. The network device may determine a wireless channel based on the ranking and may send an indication of the wireless channel to a user device.
