example 1

[0130] The eNB carries parameters related to the R-PUCCH through the SIB2 in the system broadcast message, and the mapping relationship and transmission method of the SIB2 are consistent with the LTE protocol.

[0131] The sending process of eNB and the receiving process of RN are as follows: Figure 5 As shown, the eNB configures R-PUCCH related parameters for the backhaul link, which is included in the R-PUCCH-ConfigIE, and carries the R-PUCCH-ConfigIE in the SIB2 of the system broadcast message for transmission. The RN receives the macro cell system broadcast message, and sends it in The RRC layer parses out the SIB2, and further obtains the R-PUCCH-ConfigIE, so as to obtain the configuration parameters of the eNB for the R-PUCCH. Among them, R-PUCCH-ConfigIE specifically includes the configuration instructions.

[0132] here, Figure 5 The process includes the following steps:

[0133] Step 101, the base station configures R-PUCCH resource related parameters.

[0138] The eNB carries parameters related to R-PUCCH through SIB14 in the system broadcast message. SIB14 is a newly defined SIB, which is specially used to carry parameter indications related to BackhaulLink configuration. SIB14 uses the same transmission method as the existing SIBi.

[0139] The sending process of eNB and the receiving process of RN are as follows: Figure 7 As shown, the eNB configures R-PUCCH-related parameters for the backhaul link, which is included in the R-PUCCH-ConfigIE, and carries the R-PUCCH-ConfigIE in the SIB14 of the system broadcast message for transmission. The RN receives the macro cell system broadcast message. The RRC layer parses out the SIB14, and further obtains the R-PUCCH-ConfigIE, so as to obtain the configuration parameters of the eNB for the R-PUCCH. Among them, R-PUCCH-ConfigIE specifically includes the configuration instructions.

[0146] The eNB carries parameters related to R-PUCCH through SIB14 in the system broadcast message. SIB14 is a newly defined SIB, which is specially used to carry parameter indications related to BackhaulLink configuration. SIB14 is sent on the BackhaulLink downlink subframe, and the specific scheduling information is indicated by the eNB to the RN through the R-PDCCH.

[0147] The sending process of eNB and the receiving process of RN are as follows: Figure 9 As shown, the eNB configures R-PUCCH related parameters for the backhaul link, which is included in the R-PUCCH-ConfigIE, and carries the R-PUCCH-ConfigIE in the SIB14 dedicated to the backhaul link, and in the backhaul link downlink subframe Send, and indicate the specific resource location of RNSIB14 through R-PDCCH, that is, scheduling information, RN receives SIB14 on the corresponding resource according to the configuration instruction, and obtains the R-PUCCH-ConfigIE contained in it at the RRC layer, so as to obt...

Abstract

The present invention discloses a method for indicating resource configuration of a backhaul link uplink control channel. The method includes: the network side configures and indicates to the relay station (RN) the resources related to the backhaul link physical uplink control channel (R-PUCCH) through high-level signaling. Parameters, so that the RN obtains the parameter configuration related to the R-PUCCH on the network side. The present invention also discloses a resource configuration indication system for the uplink control channel of the backhaul link. The system includes: a configuration indication unit, used for the network side to configure and indicate parameters related to R-PUCCH to the RN through high-level signaling, so that the RN can obtain The network side configures parameters related to the R-PUCCH. By adopting the method and system of the present invention, it is possible to realize the parameter configuration indication of the resource of the uplink control channel of the backhaul link.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a resource configuration indication method and system for an uplink control channel of a backhaul link. Background technique [0002] As an emerging technology, relay technology has attracted more and more attention and is regarded as a key technology of B3G / 4G. Since future wireless communication or cellular systems require perfect network coverage and support for higher rate transmission, this poses new challenges to wireless communication technology. At the same time, the cost of system construction and maintenance is more prominent. With the increase of transmission rate and communication distance, the problem of battery energy consumption has become more prominent, and future wireless communication will use higher frequencies, resulting in more serious path loss attenuation. Through the relay technology, the traditional single-hop link can be divided into multip...
