Abstract
The invention discloses an coding method of high-level signaling, relates to the field of communication and aims at using a new coding method for saving the cost of the high-level signaling and reducing the implementation complexity of a system. The specific scheme is as follows: carrying out joint coding on the interval between two adjacent cyclic shifts of format 1, format 1a or format 1b of a physical uplink control channel (PUCCH) when the orthogonal sequence indications are the same and the number of the cyclic shift occupied by the format 1, format 1a or the format 1b in mixed resource blocks; and using the high-level signaling for configuring parameters and the joint coding state of the parameters, wherein the values of the parameters are integral multiples of parameter values in the joint coding state. The coding method is used for the transmission of the uplink control signaling on the physical uplink control channel.
Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of coding method and device of high-level signaling.
Background technology
In order to keep the competitiveness of 3-G (Generation Three mobile communication system) in following 10 years, its performance, function etc. are promoted comprehensively, the 3GPP tissue has started 3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, LTE) standardization effort of system.
In the LTE system, upstream control signaling comprises: ACK (Acknowledge, confirm)/NACK (Negative Acknowledge, non-affirmation), CQI (Channel Quality Indicator, channel quality is indicated) and SRI (Scheduling Request Indicator, dispatch request indication) etc.In general, upstream control signaling is gone up transmission at PUCCH (Physical Uplink Control Channel, ascending physical signal control channel).PUCCH has six kinds of forms: form 1, form 1a, form 1b, form 2, form 2a and form 2b.Wherein, SRI adopts form 1 transmission; 1 bit ACK/NACK adopts form 1a transmission; 2 bit ACK/NACK adopts form 1b transmission; CQI adopts form 2 transmission; For short CP (CyclicPrefix, Cyclic Prefix), adopt form 2a transmission when 1 bit ACK/NACK and CQI are multiplexing, adopt form 2b transmission when 2 bit ACK/NACK and CQI are multiplexing; For long CP, adopt form 2 transmission when ACK/NACK and CQI are multiplexing.
In the LTE system, whole uplink time can be divided into several RB (Resource Block, Resource Block), and a RB is by (the Single Carrier-FrequencyDivision Multiple Access of a plurality of SC-FDMA on the time domain, single carrier-frequency division multiple access) a plurality of subcarriers on symbol and the frequency domain constitute, and are minimum scheduling unit.PUCCH is in whole uplink time, and the RB in the outside is as form 2/2a/2b transmission; Middle RB is called and mixes RB (mix RB and have at the most), mixes the existing form 1/1a/1b transmission of RB, and form 2/2a/2b transmission is arranged again; Inboard RB is as form 1/1a/1b transmission.In same RB, distinguish by orthogonal sequence indication (Orthogonal Sequence Index) and cyclic shift (Cyclic Shift) when different user adopts form 1/1a/1b transmission, distinguish by cyclic shift when different user adopts form 2/2a/2b transmission.
For PUCCH form 1/1a/1b, when orthogonal sequence indication of calculating the user and cyclic shift, need the parameter of following two high-level signalings configuration:
Presentation format 1/1a/1b under the identical situation of orthogonal sequence indication, the spacing between two adjacent cyclic shifted, span be 1,2,3}, dispose configuration mode such as table 1 with 2 bit high-level signalings:
Table 1
Expression mixes the number of the shared cyclic shift of form 1/1a/1b among the RB, span be 0,1,2 ..., 7} disposes with 3 bit high-level signalings.Wherein,
Do not exist among the expression PUCCH and mix RB.Configuration mode such as table 2:
Table 2
Therefore,
With
Need the configuration of 5 bit high-level signalings altogether.
