The original protocol process does not allow the UE to independently select the carrier, and the UE can only report the SNPL value of the working carrier configured by the network
Moreover, after receiving the same-frequency / different-frequency list of working frequency points, the UE always reports the default value before completing SNPL measurement for all adjacent primary carriers, which affects the power control performance of initial access.
[0004] It can be seen that with the existing UE uplink access method, the UE cannot select the carrier where the E-RUCCH for uplink access is located, and cannot report the accurate SNPL measurement value during access. Therefore, it is not suitable for multiple Uplink access of carrier UE

Embodiment Construction
[0012] The core idea of the present invention is: when a multi-carrier UE needs to access, the network side uses the system message block to notify the UE of the carrier information configured with E-RUCCH so that the UE can select the carrier for uplink access accordingly. The network side informs the UE of the same frequency / different frequency list of each carrier of the primary cell where the UE is located or the information used to construct the same frequency and different frequency list. In this way, the UE can determine its location based on the above information sent by the network side The same frequency / different frequency list of the cell, and then perform SNPL measurement according to the same frequency / different frequency list and select the carrier that needs to report SNPL according to the measurement result, and then the UE can select a carrier from the carriers configured with E-RUCCH and use this The carrier reports the SNPL measurement result to the base st...

The invention discloses an uplink access method in a high-speed uplink packet access (HSUPA). The uplink access method comprises the following steps of: informing user equipment (UE) of configuration information of an enhanced random-access uplink control channel (E-RUCCH) by a network side through utilizing a system message block when multi-carrier UE is required to be accessed and informing theUE of an identical-frequency or pilot-frequency list of a main cell in which the UE is located or information used for building the identical-frequency or pilot-frequency list, wherein the configuration information includes the serial number of carrier waves in which the E-RUCCH is located; determining the identical-frequency or pilot-frequency list of each carrier wave by the UE according to theinform of the network side; measuring the serving and neighbor cell pathloss (SNPL) of each carrier wave according to the identical-frequency or pilot-frequency list; determining the carrier wave of which SNPL measurement results are required to be reported according to the measurement results; selecting the carrier wave used for uplink access from the carrier waves in which the E-RUCCH is located by the UE according to the configuration information of the E-RUCCH; reporting to a base station by utilizing the carrier wave of which the SNPL measurement results are required to be reported and the SNPL measurement results. The uplink access method is suitable for the uplink access of the multi-carrier UE.
Description
Technical field [0001] The present invention relates to an access technology in a mobile communication system, in particular to an uplink access method in a multi-carrier high-speed uplink packet access (HSUPA) system. Background technique [0002] In order to support the application of high-speed packet services, the current TD-SCDMA system has introduced multi-carrier technology so that the UE can simultaneously use multiple carriers for data transmission and reception. In this way, through carrier bundling and minimal changes, the peak rate of a single user of packet services can be increased, and the flexibility of scheduling can be reflected through the expansion of resources, which can better support packet services and meet the requirements of operators for high-speed packet data services. Demand. [0003] When the system introduces the multi-carrier HSUPA technology, since a user equipment (UE) can transmit data on multiple carriers at the same time, when the UE has an upl...
