Problems solved by technology

[0004] In different scenarios, the central processor needs to determine which mode the combined cell should use to send downlink data for the UE. In the prior art, when performing mode switching, resource reconfiguration needs to be completed through high-level signaling, and signaling interaction during the switching process Many, the switching delay is large

Abstract

Embodiments of the present invention provide a transmission mode switching method and device. The method includes: a user equipment UE monitors pilot signals sent by at least two nodes; wherein, the pilot signals sent by different nodes are different, and the pilot signals are used to distinguish the at least two nodes; if the UE According to the monitored pilot signals, it is determined that the measurement results of the pilot signals of the at least two nodes meet a preset trigger condition, and a physical layer measurement result report is sent to the base station NodeB, so that the NodeB performs a downlink transmission mode switch. Therefore, the time delay when switching the downlink transmission mode is reduced.

Description

technical field [0001] Embodiments of the present invention relate to a communication technology, and in particular to a transmission mode switching method and device. Background technique [0002] In the Universal Mobile Telecommunications System (UMTS for short), a combined cell means cells corresponding to multiple coverage areas belong to one logical cell. When a user equipment (User Equipment, UE for short) moves in different coverage areas, it does not There will be high-level signaling interaction, and each transceiver node under the combined cell uses the same scrambling code to send the main common pilot channel. [0003] A combined cell is generally composed of a High Power Node (HPN for short) and a Low Power Node (LPN for short), and the nodes are connected to the central processor of the node through a low-latency link. Depending on the location, there are three transmission modes in the combined cell: Mode 1 is node selection, Mode 2 is wave velocity formation...
