Methods, apparatuses, and computer-readable mediums for wireless communication are disclosed by the present disclosure. In an aspect, an application layer in a user equipment (UE) receives, from an access layer in the UE, a quality of service (QoS) indication comprising a metric that represents a quality of one or more radio bearers used for a vehicular communication with one or more other UEs. The application layer performs a transmission control over the vehicular communication based on the QoS indication.

This disclosure provides a method for transmitting data on a physical uplink shared channel, a data transmission method, a terminal, a network device, and a chip system. A terminal receives indication information delivered by a plurality of network devices. The indication information is used to indicate a plurality of precoders (precoders). The terminal determines the plurality of precoders based on the indication information, and repeatedly sends a physical uplink shared channel PUSCH by using the plurality of precoders. Different precoders are used for at least two of the PUSCHs. In this disclosure, the PUSCH is repeatedly sent by using different precoders. This disclosure is applicable to 5G and future wireless networks.

This application relates to a measurement method, an apparatus, and a system. The method includes: A terminal device performs, based on a first measurement requirement, measurement for radio link connection quality monitoring; and if a trigger condition is met, the terminal device performs, based on a second measurement requirement, the measurement for radio link connection quality monitoring, where the second measurement requirement is obtained through relaxing based on the first measurement requirement. In this solution, the terminal device may determine whether the trigger condition is met. If the trigger condition is met, it indicates that a communication condition or a network environment of the terminal device is stable, or the terminal device has a low requirement for current communication quality. In this case, frequent measurement for radio link connection quality monitoring is equivalent to an unnecessary measurement process, and power consumption is high.

A transmitter in a frequency domain duplexing (FDD) network system is configured to receive spectral information from neighbor receiver nodes. For each of the neighbor receiver nodes, the transmitter computes an SNR at each of the plurality of frequencies, forming an SNR curve. For each of the transmit frequencies, the transmitter identifies minimum SNR values among the SNR values on the SNR curves. The minimum SNR values form a composite minimum curve. Based on the composite minimum curve, the transmitter determines whether an SNR of a current transmit frequency is above (1) a first threshold associated with an operating SNR, or (2) a second threshold associated with a maximum of the composite minimum curve. Based on the determination, the transmitter determines whether a new transmit frequency is selected to replace the current transmit frequency.

Described embodiments provide systems and methods for adjusting an operating mode for a wireless device's communications with a network. The wireless device may determine a communication profile of an application of the wireless device with the network. The wireless device may determine a type of motion of the wireless device. The wireless device may determine an operating mode for the wireless device's communications with the network, according to the communication profile and the type of motion. The wireless device may transmit a message to the network to cause the operating mode to be configured for the wireless device's communications with the network.

Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a base station may transmit, to a user equipment (UE), an indication of a dynamic switch between slot formats. The base station and the UE may communicate first data in one or more first slots according to a first slot format. The first slot format may be a first cyclic prefix-based or guard interval-based slot format. The base station may transmit control signaling to the UE to indicate a second slot format different from the first slot format. The second slot format may be a second cyclic prefix-based or guard interval-based slot format. The UE and the base station may switch to communicating second data in one or more second slots in accordance with the second slot format based on the control signaling.

Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include sensing an interference level of at least one frequency, selecting, based on the interference level, a frequency, and communicating sidelink control information (SCI) in the selected frequency.

A method implemented by a Wireless Transmit/Receive Unit (WTRU) includes receiving a DeModulation Interference Measurement (DM-IM) resource, determining an interference measurement based on the DM-IM resource, and demodulating a received signal based on the interference measurement. An interference is suppressed based on the interference measurement. At least one DM-IM resource is located in a Physical Resource Block (PRB). The DM-IM resource is located in a PRB allocated for the WTRU. The DM-IM resource is a plurality of DM-IM resources which form a DM-IM pattern, and the DM-IM pattern is located on a Physical Downlink Shared Channel (PDSCH) and/or an enhanced Physical Downlink Shared Channel (E-PDSCH) of at least one Long Term Evolution (LTE) subframe. The DM-IM resources are different for different Physical Resource Blocks (PRB) in the LTE subframe. The DM-IM is located in a Long Term Evolution (LTE) Resource Block (RB), and the DM-IM pattern is adjusted.

A method in a node is disclosed. The method comprises generating a tag for an associated data packet at a first layer, the generated tag indicating one or more parameters related to transmission of the associated data packet. The method comprises signaling the tag from the first layer to another layer. The method comprises mapping, at the another layer, the associated data packet to a logical channel based on the one or more parameters indicated by the tag, and selecting one or more resources for transmission of the associated data packet based on the mapping of the associated data packet to the logical channel.

A user equipment, UE, performs measurements based on a plurality of RLM sources received in beam-formed downlink signals, where the measurements indicate a quality of a given cell or beam. The plurality of sources comprises two or more of: first reference signals (RSs), second RSs of a different type than the first RSs, and one or more physical channel quality indicators obtained from non-reference-signal data in the beam-formed downlink signals. For each of the plurality of sources used to perform measurements, the UE determines whether a measurement for the respective source indicates an out-of-sync event in response to the measurement being below a first threshold. The UE then performs an RLM action based on determined occurrences of out-of-sync events.
