Transmission method and apparatus for uplink control signaling in time division OFDMA system
First Claim
1. A method for uplink control signaling transmission in a TDD OFDMA system, which is used for individually transmitting non-data associated control signaling in a LTE TDD system, wherein the method comprises the following steps:
- A. based on the total amount of the uplink control signaling and available uplink time slots, frequency resource being reserved for uplink control channel transmission, which is within the system bandwidth and adjacent to the upper limit and lower limit of the system bandwidth so as to form a reserved uplink control channel;
B. the uplink control signaling, which is transmitted on the reserved frequency resource for uplink control channel transmission, being transmitted by an intra-subframe frequency hopping way on the reserved uplink control channel, and a frequency-hop sequence corresponding to the signaling of each terminal UE or a group of UEs;
wherein, in the step B, transmitting on the reserved uplink control sub-channel by an intra-subframe frequency hopping way includes;
dividing the sub-frame in time domain, each of the reserved uplink control sub-channels corresponding to a time-successive frequency-hop sequence, wherein the frequency-hop sequence continuously occupying the entire sub-frame in time domain, each frequency-hop sequence being assigned on two segments of frequency resource having a distance as far as possible in frequency domain.

Abstract
A method and an apparatus for an uplink control signaling transmission in a time division duplex OFDMA system are provided for the long term evolution time division duplex (LTE TDD). A signaling processing unit reserves frequency resource for an uplink control channel according to the total amount of the uplink control signaling, and the reserved frequency resource are assigned on both sides of the frequency domain used by uplink time slots, so that the uplink control signaling of a terminal UE is transmitted on the position and the bandwidth of the reserved frequency resource. The transmitted uplink control signaling is transmitted on respective reserved uplink control sub-channels by an intra-subframe hopping way, each terminal UE or a group of UEs corresponding to a frequency-hop sequence. The present invention is simple to realizes and capable of utilizing resource repeatedly and utilizing the time domain and frequency domain diversity simultaneously.
