Embodiment 1

[0155] In this embodiment, the UE performs processing based on the DL PRS type and the first indication information.

[0156] UE side:

[0157] 1. The UE obtains information such as the DL PRS type, SSB, content carried by the PDCCH or PDSCH, first indication information, and the like according to predefined criteria in the protocol or signaling configuration. Wherein, the DL PRS type includes aperiodic PRS and semi-persistent PRS; the first indication information is used to indicate positioning QoS requirements, for example: at least one item of low latency requirements, high precision requirements and high reliability requirements.

[0158] The foregoing first indication information may be notified to the UE through various signaling. These signalings may be LPP positioning signaling, RRC signaling, MAC-CE signaling or DCI signaling, and the MAC-CE or DCI signaling may further update the configuration of the previous LPP positioning signaling or RRC signaling.

Embodiment 2

[0175] In this embodiment, the UE performs processing based on the DL PRS type and the second indication information.

[0176] UE side:

[0177] 1. The UE obtains information such as DL PRS type, SSB, content carried by the PDCCH or PDSCH, second indication information, and the like according to predefined criteria in the protocol or signaling configuration. Among them, the DL PRS type includes aperiodic PRS and semi-persistent PRS; the second indication information refers to the information used to indicate the downlink signal / channel priority; the third indication information refers to the information used to indicate the first indication information and the second indication information priority information.

[0178] The signaling of the above three indication information can be LPP positioning signaling, RRC signaling, MAC-CE signaling or DCI signaling, and the MAC-CE or DCI signaling can further update the previous LPP positioning signaling or RRC signaling configuratio...

example 1

[0186] The first predefined priority list is as follows (the basic idea is that the broadcast signal / channel has the highest priority):

[0187] First priority: Downlink broadcast signal / channel type 1——SSB (the SSB here includes the SSB of the current cell and the SSB of the adjacent cell notified in the positioning configuration message);

[0188] The second priority: downlink broadcast signal / channel type 2 - periodic PRS, CORESET#0 (ie RMSI), SI-RNTI and P-RNTI scrambled PDCCH scheduled PDSCH;

[0189] The third priority: downlink unicast signal / channel type 1 - aperiodic PRS;

[0190] Fourth priority: downlink unicast signal / channel type 2 - semi-persistent PRS;

[0191] Fifth priority: Downlink unicast signal / channel type 3——except CORESET#0, other CORESETs, RA-RNTI scrambled PDCCH scheduled PDSCH, C-RNTI scrambled PDCCH scheduled PDSCH, CSI-RS and PT-RS etc.

[0192] The collision handling schemes according to the above priorities are shown in Table 1 and Table 2.

Abstract

The invention discloses a collision processing and indicating method, equipment, a device, and a medium. The method comprises the steps: user equipment obtains the type of a downlink positioning reference signal and collision judgment information, wherein the collision judgment information is one or a combination of the following information: content carried by a downlink signal or a channel, first indication information, second indication information and third indication information, the type of the downlink positioning reference signal is an aperiodic positioning reference signal or a semi-continuous positioning reference signal, the first indication information is used for indicating a positioning time delay demand, the second indication information is used for indicating the priority of the downlink signal or the channel, and the third indication information is used for indicating priorities of the first indication information and the second indication information; according to the downlink positioning reference signal type and the collision judgment information, determining that the downlink positioning reference signal or other downlink signals or channels are selected to be discarded on the collided orthogonal frequency division multiplexing symbols. The invention can improve the positioning precision and reduce the positioning time delay.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a collision processing and indication method, equipment, device and medium. Background technique [0002] 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) NR (New Radio, New Radio) defines the periodic DL PRS (downlink positioning reference signal; DL: downlink, Down Link; PRS: positioning reference signal, Positioning Reference Signal) and the SSB (synchronization signal / physical broadcast channel signal block (or synchronization signal block), Synchronization Signal and PBCH block, SS / PBCH) of this cell / neighboring cell The processing scheme when a collision occurs, the scheme is mainly as follows : [0003] For the serving TRP (transmission and reception node, Transmission and Reception Point), UE (user equipment, User Equipment) assumes that the DL PRS is not mapped to any OFDM (Orthogonal Frequency Division Multiplexing) s...
