Problems solved by technology

However, at this time, only the PUCCH is used for receiving / receiving error transmission, but the UE has no PUCCH resource, thus causing the UE to fail in receiving / receiving an error report, Seriously affect downlink data reception
[0016] In addition, when the UE loses uplink synchronization as described above, the allocated sounding reference symbols cannot be used, and the base station cannot use the sounding reference symbols transmitted by the UE and used for frequency-based scheduling, so Affects uplink transmission performance

Embodiment Construction

[0039] Please refer to image 3 , image 3 is a schematic diagram of the wireless communication system 10 . The wireless communication system 10 is a Long Term Evolution (LTE) system or other wireless communication systems, which is briefly composed of a network terminal and multiple user terminals. exist image 3 In , the network end and the user end are used to illustrate the architecture of the wireless communication system 10 . The wireless communication system 10 may be a long-term evolution wireless access network (evolved-UTAN, EUTRAN), which may include a plurality of evolved base stations (eNBs) according to actual needs, and the user end may be a mobile phone, a computer system, etc. device. In addition, according to the transmission direction, the network end and the user end can be regarded as a transmitter and a receiver. For example, for uplink (UL) transmission, the UE is the transmitter and the network is the receiver; for downlink (DL) transmission, the n...

Abstract

The invention provides a method of improving uplink signaling transmission for a user equipment of a wireless communication system. The method includes performing a random access procedure, and applying resources of a physical uplink control channel and an uplink symbol used for channel quality determination when a message of the random access procedure received from a network of the wireless communication system is performed successfully.

Description

technical field [0001] The present invention refers to a method for a wireless communication system, especially a method for improving uplink signaling transmission in a wireless communication system and related devices. Background technique [0002] The Long Term Evolution (LTE) wireless communication system formulated by the 3rd Generation Partnership Project (3GPP) is currently considered to provide high data transmission rate, low latency, and packet optimization. And a new wireless interface and wireless network architecture to improve system capacity and coverage. The physical layer of the LTE wireless communication system adopts the Orthogonal Frequency Division Multiple Access (OFDMA) technology with a cyclic prefix in the downlink transmission, while the uplink transmission uses A single carrier frequency division multiple access (SC-FDMA) with a cyclic preamble is adopted. In the LTE wireless communication system, the Evolved Universal Terrestrial Radio Access Ne...
