Description
Technical field
The present invention relates to the communications field, more specifically, relate to multiplexing method of a kind of Physical Uplink Control Channel and device.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system, LTE-A (LTE Advanced, the LTE enhancing) system, IMT-Advanced (International Mobile Telecommunication Advanced, senior international mobile communication system) all be with OFDM (Orthogonal Frequency Division Multiplexing, OFDM) technology be the basis.Mainly the data mode of time-frequency bidimensional in ofdm system.As shown in Figure 1, Resource Block in LTE, LTE-A (Resource Block is called for short RB) is defined as the OFDM symbol in continuous 1 time slot (slot) on time-domain, and continuous 12 or 24 subcarriers on frequency domain are so 1 RB comprises
Individual Resource Unit (Resource Element is called for short RE), wherein N
SymbThe number of representing the OFDM symbol in 1 slot,
The number of expression Resource Block continuous subcarrier on frequency domain.RB is mapped in and then is called Physical Resource Block (Physical Resource Block is called for short PRB) on the physical resource.
(the Physical Uplink Control Channel of PUCCH in the present LTE system, Physical Uplink Control Channel) is used for loading ACK/NACK (Acknowledgement/Negative Acknowledgement, confirmed/non-confirmed information), CQI (Channel Quality Indicator, the channel quality indication), SRI information such as (Scheduling Requirement Indicator, dispatch request indications).The PUCCH of different-format is used for sending and comprises: SRI, uplink ACK/NACK, CQI feedback, and perhaps different ascending control information such as CQI feedback+ACK/NACK, as shown in the table, PUCCH has different-format as shown in the table:
Wherein, PUCCH format 1/1a/1b's is multiplexing by frequency domain CDM (Code Division Multiplexing between different user, code division multiple access) code (Zadoff-Chu cyclic shift, the ZC cyclically shifted sequences) and time domain CDM code (orthogonal cover, orthogonal code) determines, promptly the Cyclic Shift by orthogonal code and CAZAC (Constant Amplitude Zero Auto Correlation, constant amplitude zero auto-correlation) sequence distinguishes different users; The multiplexing of PUCCH format 2/2a/2b determines that by frequency domain CDM code (ZC cyclic shift) promptly the Cyclic Shift by the CAZAC sequence distinguishes different users between different user.
As shown in Figure 2, the link that introducing relay (via node) in the LTE-A system has increased between new link: eNode-B (base station) and the relay afterwards is called backhaul link (back haul link or repeated link), relay and UE (User Equipment, subscriber equipment) link between is called access link (access link), and the link between eNode-B and the UE is called direct link (link direct transfers).
As shown in Figure 3, the PUCCH of terminal to base station and via node are to R-PUCCH (the Relay link-Physical Uplink Control Channel of base station, the Physical Uplink Control Channel of repeated link) mode of frequency hopping between the employing time slot, promptly transmit PUCCH or R-PUCCH on the both sides of upstream band, frequency band intermediate conveyor PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) or R-PUSCH.
Fig. 4 shows and uses Normal CP (normal cyclic prefix), and the ZC cyclically shifted sequences is spaced apart the schematic diagram of the interior resource channelizing of Resource Block in 2 o'clock, wherein, CS_index be ZC cyclically shifted sequences index (" 0 ", " 1 ", " 2 " ..., " 11 "), OC_index is orthogonal code sequence index (" 0 ", " 1 ", " 2 ").
During relaying (inband-relay), relay can't receive and dispatch simultaneously, needs 1 " gap " (at interval) to finish the conversion of a transmitting-receiving or a receipts state between transmitting and receiving in adopting band.And the PUCCH of LTE does not have " gap " at present, so cause the PUCCH of terminal to base station and via node to have difference to the design between the R-PUCCH of base station.
At present, research for downlink relay link is a focus, control information of being carried in the Physical Uplink Control Channel as the design of R-PDCCH (Physical Downlink Control Channel of repeated link, Relay link-Physical Downlink Control Channel), repeated link such as the feedback of ACK/NACK are regularly etc.But in the prior art, do not launch research at the Physical Uplink Control Channel of repeated link and the multiplexing method of the Physical Uplink Control Channel of the link that direct transfers.

Described resource multiplex unit is multiplexing on same resource block the time with the Physical Uplink Control Channel of the Physical Uplink Control Channel of repeated link and the link that direct transfers, same Resource Block is distributed to repeated link and the link that direct transfers simultaneously, on this Resource Block, the Physical Uplink Control Channel multiplexing via node of difference of the Physical Uplink Control Channel of repeated link and the link that direct transfers and the ascending control information of terminal.
14. device as claimed in claim 13 is characterized in that,
Described resource multiplex unit is multiplexing on same resource block the time with the Physical Uplink Control Channel of the Physical Uplink Control Channel of repeated link and the link that direct transfers, and its multiplex mode is a resource multiplexing or resource hybrid multiplex fully;
Wherein, multiplexing fully all orthogonal sequence resources, cyclic shift resource or orthogonal sequence resource and the cyclic shift resource that is meant the multiplexing described Resource Block of Physical Uplink Control Channel of the Physical Uplink Control Channel of repeated link and the link that direct transfers of described resource; Described resource hybrid multiplex is meant part orthogonal sequence resource, cyclic shift resource or orthogonal sequence resource and the cyclic shift resource of the multiplexing described Resource Block of Physical Uplink Control Channel of the Physical Uplink Control Channel of repeated link and the link that direct transfers.
15. as claim 11,12,13 or 14 described devices, it is characterized in that,
Described resource multiplex unit is respectively the repeated link Resource Block different with the link assignment that direct transfers in that the Physical Uplink Control Channel of the Physical Uplink Control Channel of repeated link and the link that direct transfers is multiplexing on the different resource piece time;
Wherein, distributing on the Resource Block of repeated link, the Physical Uplink Control Channel of repeated link is the ascending control information of multiplexing via node only; On the Resource Block of distributing to the link that direct transfers, the Physical Uplink Control Channel of the link that direct transfers is the ascending control information of multiplex terminal only.
