Description

A method and device used in a communication node for wireless communication

technical field

The present application relates to a transmission method and device in a wireless communication system, in particular to a mobility transmission method and device.

Background technique

Traditional network controlled (Network Controlled) mobility includes cell level mobility (cell level) and beam level mobility (beam level), where cell level mobility depends on RRC (Radio Resource Control, Radio Resource Control) signaling, beam-level mobility does not involve RRC signaling. Before 3GPP (the 3rd Generation Partnership Project, third-generation partnership project) R16, beam-level mobility was only aimed at beam management (Beam Management) in a single cell. The 3GPPRAN#80 meeting decided to carry out the "Further enhancements on MIMO for NR" work item (Work Iterm, WI), which supports multi-beam (multi-beam) operation (operation), targeting Layer 1 (Layer 1, L1)/Layer 2 (Layer 2, L2)-centric inter-cell mobility (L1/L2-centric inter-cell mobility) and inter-cell multiple TRP (multiple Transmit/Receive Point, mTRP) are enhanced.

Contents of the invention

In order to realize inter-cell L1/L2 mobility or inter-cell mTRP, when UE (User Equipment, user equipment) is in the serving cell, the network configures the wireless parameters of another cell for the UE through RRC messages, and the UE is in the serving cell (Serving cell) ), the TRP of another cell can be used for data transmission, and the other cell and the serving cell have different PCIs (Physical Cell Identifier, physical cell identifier). When the UE uses the TRP of another cell for data transmission in the serving cell, if the current Radio Link Monitoring (Radio Link Monitoring) mechanism is used, it will trigger Radio Link Failure (RLF) prematurely, affecting UE performance. Therefore, it is necessary to enhance the wireless link monitoring mechanism.

Aiming at the above problems, the present application provides a solution. In the description of the above problem, the uu port scenario is used as an example; this application is also applicable to, for example, a sidelink (sidelink) scenario, and achieves a technical effect similar to that of the uu port scenario. In addition, adopting a unified solution for different scenarios can also help reduce hardware complexity and cost.

receiving a first message; the content of the first message depends on whether a first set of conditions is met;

Wherein, the first process includes: the receiver of the first signaling evaluates the second type of radio link quality according to at least part of the RS resources in the second RS resource group, and whenever the evaluated second type When the radio link quality is worse than a second threshold, the receiver of the first signaling reports a second-type indication to a second higher layer of the receiver of the first signaling; as receiving the In response to the second type of indication, the receiver of the first signaling starts or restarts a second timer and increases the first counter by 1; as the first counter after the increase is not less than the second value In response, the recipient of the first signaling triggers a BFR or a random access procedure; in response to expiration of the second timer, the recipient of the first signaling sends the first The counter is set to 0;

The first type of radio link quality is evaluated by the receiver of the first signaling according to at least part of the RS resources in the first RS resource group, whenever the evaluated first type of radio link quality When worse than the first threshold, a first type indication is reported by the recipient of the first signaling to a first higher layer of the recipient of the first signaling; In order for the receiver to continuously receive the response that the number of indications of the first type reaches a first value, a first timer is started; the first timer is determined to be expired; as the first timer is determined In an expired response, a first message is sent; the first set of conditions includes that the first counter is less than the second value, or is triggered by the increment of the first counter being not less than the second value At least one of the at least one BFR is not terminated, or at least one random access procedure triggered by the increment of the first counter being not less than the second value is not successfully completed.
