Problems solved by technology

For the new carrier technology, if the base station only maintains the synchronous transmission of the new carrier and the backward compatible carrier, once the PSS / SSS is not configured in the new carrier, then the new carrier and the backward compatible carrier may not be guaranteed on the UE side. Synchronization, for example, the new carrier and the backward compatible carrier have not been transmitted by the same node, or the new carrier and the backward compatible carrier do not belong to the same band (bandwidth), and the carrier frequency is very different, so it cannot be synchronized

Embodiment 1

[0116] There are two carriers in a certain system. It is assumed that one is a carrier with backward compatibility and the other is the new carrier. In this embodiment, it is assumed that no independent PSS / SSS is configured on the new carrier.

[0117] First, the base station pairs the backward compatible carrier with the new carrier, and sends the pairing information to the UE in the backward compatible carrier. Since the new carrier does not support direct access by UEs, all UEs access the system from backward compatible carriers, and then the base station configures and schedules the carriers for the UEs. For example, a new carrier is configured for some UEs.

[0118] Specifically, the base station sends information about the pairing of the backward compatible carrier and the new carrier to the UE, so that the UE knows which new carrier the backward compatible carrier is paired with. The base station sends some common channels and important system information in the new c...

Embodiment 2

[0125] This embodiment is basically the same as Embodiment 1. The difference is that if the UE judges that the new carrier is not synchronized with the backward compatible carrier through the CSI-RS of the new carrier, the UE needs to perform further calculations based on the CSI-RS , to determine the specific time difference between the new carrier and the backward compatible carrier.

[0126] There are two carriers in a certain system. It is assumed that one is a carrier with backward compatibility and the other is the new carrier. In this embodiment, it is assumed that no independent PSS / SSS is configured on the new carrier.

[0127] First, the base station pairs the backward compatible carrier with the new carrier, and sends the pairing information to the UE in the backward compatible carrier. Since the new carrier does not support direct access by UEs, all UEs access the system from backward compatible carriers, and then the base station configures and schedules the carri...

Embodiment 3

[0136] This embodiment is different from Embodiments 1 and 2. In Embodiment 3, the process of configuring and sending the necessary information of the new carrier is focused on, so that the UE can obtain the information in time.

[0137] There are two carriers in a certain system, and it is assumed that one is a carrier with backward compatibility and the other is the new carrier. In this embodiment, it is assumed that no independent PSS / SSS is configured on the new carrier.

[0138] For a UE that accesses a backward compatible carrier, the base station may configure a new carrier for it. According to the present invention, if the base station plans to configure a backward compatible carrier for a certain UE, then the base station needs to send the necessary information of the new carrier to the UE. At this time, the base station includes the information unit structure of the new carrier in the RRCConnectionReconfiguration message, and gives the information in the structure Th...

Abstract

The present invention discloses an information transmission and configuration method and device, comprising: a base station configures a carrier in a long-term evolution (LTE), and sends configuration information of the carrier to a user equipment (UE), and the configuration information of the carrier includes One or more of carrier bandwidth, cell identity (ID), cyclic prefix (CP) type, channel state information measurement pilot (CSI-RS) configuration information and downlink transmission mode. In the present invention, for the new carrier in LTE, the carrier configuration information is sent to the user equipment, so that the user equipment can use the new carrier according to the carrier configuration information when the base station configures the user equipment to use the new carrier.

Description

technical field [0001] The invention relates to the field of mobile wireless communication, in particular to an information transmission and configuration method and device. Background technique [0002] With the development of the mobile communication industry and the increasing demand for mobile data services, people have higher and higher requirements for the speed and quality of service of mobile communication. Therefore, before the third generation of mobile communication (3G) has not been commercialized on a large scale, The research and development of the next-generation mobile communication system has already started, and the typical one is the long-term evolution (LTE) project launched by the third generation partnership project (3GPP). The highest spectrum bandwidth that the LTE system can provide is 20MHz ( megahertz). With the further evolution of the network, LTE-A (Evolved LTE), as an evolution system of LTE, can provide up to 100MHz of spectrum bandwidth and ...
