Systems and techniques or transmitting and receiving a sounding reference signal (SRS) in a wireless communication system. In some implementations, a method for transmitting, by a terminal, an SRS in a wireless communication system includes: receiving configuration information for transmission of the SRS from a base station; and transmitting the SRS to the base station by using one or more SRS resources for transmission of the SRS, the configuration information including the one or more SRS resources and information relating to usage of the one or more SRS resources, wherein a guard period relating to the one or more SRS resources is configured, and when the transmissions of the guard period and a particular uplink channel configured for the terminal overlap each other, the priority between the guard period and the particular uplink channel is configured to be the same as that between the SRS and the particular uplink channel.

The channel and signal transmission method applied to a communication device at a sending end includes: when transmitting at least two data transmission resources, send the data transmission resources, according to at least one of QCL information of the data transmission resources and a preset rule, where a data transmission resource includes at least one of a signal and a channel.

Apparatuses, methods, and systems are disclosed for multiple resource allocation mode configurations. One method includes receiving information indicating a plurality of resource allocation mode configurations. Each resource allocation mode configuration corresponds to a logical channel of a plurality of logical channels. The method includes determining a plurality of data transmission scheduling modes for the plurality of logical channels. Each data transmission scheduling mode corresponds to a logical channel of the plurality of logical channels based a resource allocation mode configuration of the logical channel, and each data transmission scheduling mode comprises: a first scheduling mode; a second scheduling mode different from the first scheduling mode; or a third scheduling mode comprising the first scheduling mode and the second scheduling mode. The method includes transmitting a buffer status report based on the plurality of the data transmission scheduling modes.

Methods, systems, and devices for wireless communications are described that provide multiplexing of one or more control or shared channel communications on one or more uplink component carriers (CCs). Uplink control channel communications may be multiplexed within each CC that is configured for uplink control channel transmissions and, after multiplexing the control channel communications within each CC, multiplexing with shared channel communications may be performed. Multiplexed or un-multiplexed control channel communications may be multiplexed with a shared channel communication on a same or a different CC, where the multiplexing on the same CC or on the different CC is based at least in part on a configuration associated with concurrent shared channel and control channel communications. Further a priority associated with one or more of the shared channel communications or the control channel communications may be used to determine channels to multiplex together on a CC.

A wireless entity, such as a user equipment (UE) or transmission reception point (TRP), receives and processes aggregated positioning reference signals (PRS) to increase the effective PRS bandwidth, thereby increasing positioning accuracy, such as time of arrival measurements. An aggregated PRS includes one or more PRS components that are transmitted from a same transmitting entity. Each PRS component may be, e.g., a separate PRS resource associated with a contiguous frequency-domain bandwidth or may be, e.g., a plurality of frequency-domain bandwidths spanned by a single PRS resource. PRS components of an aggregated PRS that are unpunctured, e.g., do not collide with higher priority signals, are aligned in time domain, and are configured with common constraints are processed jointly assuming that the PRS components are transmitted from a same antenna port, thereby increasing the effective PRS bandwidth.

A scheduling request (SR) configuration method and sending method, and a corresponding apparatus are provided, to resolve a prior-art problem of a scheduling request configuration method and sending method, and a corresponding apparatus. The scheduling request configuration method includes: receiving, by a user equipment (UE), control signaling sent by a network device, where the control signaling is used to configure, for the UE, an SR configuration associated with at least one logical channel and at least two SR resource configurations associated with the SR configuration, and the SR resource configurations indicate physical resources used to signal an SR associated with the at least one logical channel; and signaling, by the UE based on a physical resource indicated by one of the at least two SR resource configurations, an SR associated with one of the at least one logical channel.

The present application discloses a method for transmitting an uplink signal and a terminal device, including: receiving, by a terminal device, uplink grant information transmitted by a network device, where the uplink grant information is used to instruct the terminal device to transmit a first uplink channel in a first sub-slot and to transmit a second uplink channel in a second sub-slot, where the first uplink channel comprises first uplink data and does not comprise a reference signal, the second uplink channel comprises the first reference signal, the first sub-slot and the second sub-slot are adjacent sub-slot on a first carrier, the first sub-slot is located previous to the second sub-slot, and the first reference signal is used to demodulate the first uplink data; determining, by the terminal device, whether to transmit the first uplink channel in the first sub-slot according to a priority of an uplink channel.

Embodiments of this application provide a conflict resolving method and a terminal device. When uplink transmission conflicts with sidelink transmission in time, the terminal device can resolve the data transmission conflict based on a ProSe per-packet priority (PPPP) of data on a sidelink and a limit, thereby satisfying data transmission requirements in Release 15 and subsequent Releases. The method is applied to terminal-to-terminal communication. A terminal device needs to transmit sidelink data on M first-type carriers and transmit uplink data on N second-type carriers, and M and N are positive integers. The method includes: determining, by the terminal device based on a PPPP of the sidelink data transmitted on the M first-type carriers and a first limit, to preferentially transmit the sidelink data on some or all of the M first-type carriers, or to preferentially transmit the uplink data on some or all of the N second-type carriers.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive multiple uplink grants that schedule uplink transmissions for two different radio access technologies (RATs) during overlapping time resources. The UE may adjust the power for one of the uplink transmissions based on the temporal proximity of the second received uplink grant relative to the first uplink transmission. The UE may adjust the power of the uplink transmission by partially or completely reducing its power.

Embodiments are presented herein for adjusting the conduct of routine communications of safety messages in V2X networks in order to conserve resources in participating power-limited devices while satisfying V2X system latency demands. Scheduling (e.g., timing and/or frequency) of safety message communications performed by certain UE devices participating in a V2X network may be dynamically adjusted according to various criteria, such as factors relating to the DRX cycle schedule, motion or mobility, traffic environment, and/or battery or power capabilities of the UE devices, which may conserve UE resources and power consumption. Certain UE devices may efficiently transmit safety messages to the V2X network using one of several proposed RACH-based procedures. In some embodiments, the size of safety message communications may be reduced through various compression techniques, and/or by reducing the amount of contained information, e.g., by omitting certain parameters, which may reduce the resources consumed by performing safety message communications.
