Patent ID: 8503337

Claim:
A method for transmitting a physical uplink control signal in a time division duplex system, wherein the uplink control signal is more than 2 bits, comprising the following steps of: a base station NodeB distributing a plurality of uplink channel code resources of a physical uplink control channel (PUCCH) for a user equipment (UE), and making an agreement with the UE about different contents represented by the usage of different uplink channel code resources to transmit the uplink control signal; the UE selecting one or more uplink channel code resources from the distributed uplink channel code resources according to the content of the uplink control signal to be transmitted and the agreement, and transmitting the uplink control signal on the PUCCH; when transmitting the uplink control signal, the UE selecting one or more uplink channel code resources from the plurality of uplink channel code resources distributed by the NodeB for the UE according to the content of the uplink control signal to be transmitted, wherein the selected uplink channel code resources indicate the part of the content of the uplink control signal that cannot be carried on the PUCCH, and the UE performing the time-frequency spreading using the selected uplink channel code resources and transmitting the remaining content of the uplink control signal on the PUCCH.
