This application relates to the intelligent cockpit field and provides a communication method and apparatus, to reduce communication interference between devices. In this application, if priorities of one or more second devices are lower than a priority of a first device, the first device sends second information to the one or more second devices, where the second information includes a communication resource allocated by the first device to the one or more second devices and the priority of the first device. When the priorities of the one or more second devices are lower than the priority of the first device, the first device may allocate the communication resource to the one or more second devices. This can avoid communication interference between different communication domains that is caused by a conflict between communication resources, and improve communication performance of the devices.

Embodiments of this application provide a device-to-device based resource determining method and device, which may be applied to a D2D system (for example, a system such as an internet of vehicles, V2X, or V2V). The method includes: receiving first information sent by a first terminal device, where the first information indicates a second terminal device to send assistance information; and sending the assistance information to the first terminal device, where the assistance information is used to assist the first terminal device in selecting a resource for data transmission. The second terminal device assists the first terminal device in determining the resource for data transmission, instead of completely determining, by a terminal device that sends data, the resource for data transmission.

A downlink reception triggering method, a terminal, and a network-side device are provided. A method on a terminal side includes transmitting a first uplink signal, where the first uplink signal is used to trigger a first downlink reception.

This application provides a physical downlink control channel monitoring method and an apparatus. The method includes: determining that a first monitoring capability of a terminal device is used to monitor a physical downlink control channels of a cell set of the terminal device, determining N non-overlapping time units of the cell set in one slot, where a start location of each of the N time units is based on a span of a cell in the cell set, and allocating the first monitoring capability in the cell set based on the N time units to separately monitor a physical downlink control channel of each cell in the cell set, so that in a carrier aggregation (CA) scenario, the terminal can monitor a physical downlink control channel at a granularity of a span.

The method includes: adjusting timing of a first link state based on first signaling, where the first link state is a link state of a first relay device or a terminal; and the first signaling is provided by a parent node of the first relay device, or a parent node of the terminal, or a first network-side device, where the parent node is a last-hop device of the first relay device or the terminal.

The present disclosure relates to the technical field of communications, and disclosed are a resource reservation method and apparatus, a device and a storage medium. The method comprises: once LBT is successful, sending sidelink control information, wherein the sidelink control information is used to indicate N transmission resources reserved for a first transmission block, and the upper limit value of N is an integer greater than 3. Provided in the embodiments of the present application is a method for indicating transmission resources reserved by a terminal device when performing sidelink transmission on the basis of an unlicensed spectrum. Moreover, the sidelink control information sent by the terminal device may indicate more than three transmission resources, so that the reserved transmission resources may be indicated as much as possible in the sidelink control information.

Power control methods, user equipments, base stations and computer-readable storage media are provided. The method includes: a user equipment determines RSRP corresponding to each of carriers, and determines one or more carriers meeting a first preset condition based on the RSRP corresponding to each of the carriers, where the one or more carriers meeting the first preset condition refer to a carrier generating image interference. Then, the UE reports indication information corresponding to the one or more carriers meeting the first preset condition to a base station to make the base station adjust transmission power of the one or more carriers meeting the first preset condition, so as to alleviate large power difference of each carrier, thus, impact of demodulation performance of some carriers may be reduced, and decline of overall communication performance of carrier aggregation may be alleviated.

Disclosure provides a method and a device in a UE and a base station for wireless communication. A first node receives a first signaling and a second signaling, and transmits K signals in K air interface resource blocks respectively. The first signaling is used for determining a first air interface resource block and a first bit block, and the second signaling is used for determining K air interface resource blocks; the first air interface resource block and the K air interface resource blocks are overlapping in time domain; the K signals all carry a second bit block; a first signal subset among the K signals is spatially correlated to a first reference signal, and a second signal subset is spatially correlated to a second reference signal. The above method improves the reliability of transmission of uplink control information transmitted on the uplink physical layer data channel.

A terminal according to one embodiment of the present invention determines and reports a specific codebook-based HARQ-ACK on the basis of the result of receiving a plurality of PDSCHs, and, on the basis of a first-type codebook-based HARQ-ACK having been set for scheduling of the plurality of PDSCHs, the terminal can perform first start symbol and length indicator value (SLIV) pruning on the basis of a set of the SLIVs of PDSCHs, which can be potentially scheduled on each slot of a bundling window determined on the basis of a plurality of candidate PDSCH-to-HARQ feedback timing values, and perform second SLIV pruning on the basis of a set of the SLIVs of PDSCHs, which can be potentially scheduled even on at least one slot that does not belong to the bundling window.

Disclosed are techniques for wireless communication. In an aspect, a relative location anchor group (RLAG) may facilitate a position estimation procedure in an environment where absolute position estimation accuracy is below a threshold. An absolute position estimate derived via the RLAG may optionally be transformed to a true (or more accurate) position estimate via transformation information. In some cases, new anchors may be added to the RLAG after performing a position estimation procedure with the RLAG. In other designs, a local coordinate system (LCS) may be used for position estimation in lieu of a global coordinate system (GCS), such as WGS 84.
