At least one of object, such as A and/or B are met, indicates to include independent A, independent B and A and B have three kinds of situations.
In embodiments of the present invention, " illustrative " or " such as " etc. words for indicate make example, illustration or explanation.
Be described as in the embodiment of the present invention " illustrative " or " such as " any embodiment or design scheme be not necessarily to be construed as
Advantage more preferably or more than other embodiments or design scheme.Specifically, use " illustrative " or " such as " etc. words
It is intended to that related notion is presented in specific ways.
Several technical points are introduced first below:
(1) LTE hybrid automatic repeat-request (Hybrid Automatic Repeat reQuest, HARQ)-ACK weight
It is multiple:
Some UE can be configured to repeat to send in multiple continuous sub-frame of uplink same by base station (such as eNB)
ACK/NACK transmission.Do so the reliable of the ack/nack signal for being beneficial to the UE for the power limited for guaranteeing to be located at cell boarder
Property.This characteristic is known as ACK/NACK and repeats (Repetition) (being known as HARQ-ACK Repetition in agreement).
HARQ-ACK Repetition is configured by the specific parameter ACK/NACK Repetition of UE, packet
It is (duplicate comprising the ACK/NACK transmission including initial ACK/NACK transmission to include repetition factor (repetitionFactor)
Number), parameter n1PUCCH-AN-Rep is (in ACK/NACK repetition, for replying ACK/NACK on antenna port 0
PUCCH resource) etc. parameters.
If UE enables ACK/NACK repetition, UE can repeat to send any ACK/NACK transmission NANrep
Secondary, wherein NANrep is configured by repetitionFactor, which will be including initial ACK/NACK transmission statistic.
If UE is received not with Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH)
Physical Downlink Shared Channel (PDSCH) transmission (downlink semi-persistent scheduling (Semi-Persistent Scheduling, SPS)
The PDSCH that frame is sent), UE, which will use, is allocated to the PUCCH resource of SPS to send corresponding ACK/NACK and feed back NANrep times.
If the PDSCH transmission that UE is received has a corresponding PDCCH, or receives the PDCCH of an instruction SPS release, then just
The PUCCH resource that the ACK/NACK of beginning is used can be based on first (first) CCE (Control Channel of corresponding PDCCH
Element, control channel unit) index (index) is calculated, and subsequent NANrep-1 duplicate ACK/NACK is anti-
Feedback will use n1PUCCH-AN-Rep (respective antenna port 0) and n1PUCCH-AN-RepP1-r10 is (right when 2 antenna transmission
Answer antenna port 1) configuration resource transmission.
In frequency division duplex (Frequency Division Dual, FDD) or time division duplex (Time Division
Duplexing, TDD) under, ACK/NACK repetition is only applicable to UE and is configured with a serving cell (serving
Cell scene), i.e., do not support carrier wave to polymerize.HARQ binding is only applicable to for TDD, ACK/NACK repetition
(bundling)。
ACK/NACK Repetition does not support carrier wave to polymerize.This is because it will affect the performance of downlink, and
Carrier wave polymerization often assumes that the transmission of control signaling can't encounter the problem of transimission power deficiency.
(2) LTE PUCCH frequency hopping (Frequency Hopping, FH)
In order to obtain frequency diversity gain in LTE, PUCCH uses frequency hopping in two time slots (slot) of a subframe
Mode transmitted, i.e. in two slot PUCCH Physical Resource Block (Physical Resource Block, PRB) respectively
Positioned at two edges of system bandwidth.
(3) LTE PUCCH resource indexes the mapping of physical resource
The resource method of determination of PUCCH is in LTE, provides by the first CCE index (index) of PDCCH or ACK/NACK
Source indicator (ARI) or ACK/NACK resource deviant (ARO) obtain PUCCH resource index, such as 1 (format of format
1) it, is expressed asThen pass throughVariable m is calculated, m is the parameter in technical standard, indicates PUCCH used resource
The serial number of block (Resource Block, RB), obtains the Physical Resource Block n of PUCCH finally by mPRB。
Specifically, UE first passes through PDCCH first CCE index or ARI or ARO and obtains PUCCH resource
indexThen it is utilizingWith other associated radio resources control (Radio Resource Control,
RRC) parameter configured obtains variable m, and the calculating of m is unrelated with Slot symbol.Then n is obtained by mPRB, this step calculate in
Time slot in one subframe is related, to support frequency hopping of the PUCCH between two time slots of a subframe.
(4) new wireless (New Radio, NR) short PUCCH
Meet different business demands in NR, introduce the PUCCH of distinct symbols length: short PUCCH is (when continuing
Between for 1 or 2 orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA) symbol
Number) and long PUCCH (duration is 4~14 OFDMA symbols).For the short PUCCH of 1 symbol (1-symbol), due to
Only one OFDM symbol of time domain length, can not support frequency hopping, therefore can not obtain frequency diversity gain.
