Description
Technical field
The present invention relates to wireless communication field, particularly relate to transmission method and the equipment of a kind of power control command.
Background technology
Technology of Internet of things is in the ascendant, needs to support machine-type communication (MachineTypeCommunications, MTC) function in 3-G (Generation Three mobile communication system) and its long evolving system (LongTermEvolution, LTE).
Machinery compartment (M2M, Machine-to-machine) communication is as a kind of novel communication theory, its objective is to organically combine the communication technology of number of different types, as: machine-to-machine communication, apparatus control communication, man-machine interaction communication, mobile interchange communication, thus promote the development of social production and life style.The business of anticipated following Human To Human's communication may only account for the 1/3 of whole terminal market, and greater amount of communication is machinery compartment (little bandwidth system) communication service.
Current mobile communications network is for interpersonal communication scheme, such as: the determination etc. of network capacity.The mechanism of mobile communication system is optimized by the feature being it desired to utilize mobile communications network to be accomplished by according to little bandwidth system communicates to support little bandwidth system communication, so as in the case of traditional person to person's communication is not subject to or is subject to less impact, little bandwidth system communication is better achieved.
The MTC characteristics more that may be present being currently recognized that have: MTC terminal has Hypomobility；The time that MTC terminal and network side carry out data transmission is controlled, i.e. MTC terminal can only access within the time period that network is specified；The data transmission that MTC terminal and network side are carried out is the highest to requirement of real-time to data transmission, it may be assumed that have time tolerance；MTC terminal energy constraint, it is desirable to extremely low power consumption；The information transmission of small data quantity is only carried out between MTC terminal and network side；MTC terminal can be managed in units of group；Etc..
One actual MTC terminal can have above-mentioned one or more characteristics.
In order to support that a large amount of MTC terminal carries out data transmission simultaneously, a kind of scheme is the data field at LTE system bandwidth of operation, configures multiple little wide frequency point, is respectively configured a part of MTC terminal and carries out data transmission, as shown in Figure 1 in each little wide frequency point.
nullIn LTE system，Main by the DCI with Downlink Control Information (DCI) form 3 and 3A on Physical Downlink Control Channel (PDCCH)，Indicate the Physical Uplink Control Channel (PhysicalUplinkControlChannel of one group of terminal (UE)，Or Physical Uplink Shared Channel (PhysicalUplinkSharedChannel PUCCH)，PUSCH) power controls (TransmissionPowerControl，TPC) order，The power that wherein corresponding relation of UE and TPC command is configured by high level controls mark (TPC-Index) instruction，DCI format 3 and the main distinction of 3A are that the bit number of TPC command is different，In DCI format 3, the bit number of each TPC command is 2 bits，In DCI format 3, the bit number of each TPC command is 1 bit，Its circulation CRC (CRC) is to control Radio Network Temporary Identifier (RadioNetworkTemporaryIdentifier by power，TPC-RNTI) scramble.DCI format 3, for transmitting the TPC command of PUCCH and PUSCH, uses dibit to carry out power adjustment.
In DCI format 3, its information field structure is as follows:
TPC command 1, TPC command 2 ..., TPC command N；
Wherein,And Lformat0It is the size of the information bit of DCI format 0, including the filling bit in DCI format 0.If1 bit is filled in DCI format 3.
In DCI format 3A, its information field structure is as follows:
TPC command 1, TPC command 2 ..., TPC command M；
Wherein, M=Lformat0, and Lformat0It is the size of the information bit of DCI format 0, including the filling bit in DCI format 0.
To sum up, in existing LTE standard, the power control command of multicast is to be transmitted by the DCI format 3 or 3A of PDCCH.Owing to the LTEUE in existing standard has the data reception capabilities not less than system bandwidth of operation, so, no matter PDCCH any position terminal in system bandwidth, the most there is not the difficulty of reception in existing terminal, and in the case of multiple little wide frequency points configure, the semi-persistent scheduling service of great amount of terminals may transmit on some frequency, can also transmit on multiple frequencies, for the semi-persistent scheduling service of the terminal on multiple little wide frequency points, current standard is also not specified by above-mentioned in the case of the power control command of multicast how to be transmitted.If without relevant regulations, then little bandwidth terminals may be caused cannot to know how the power control command of its multicast form is transmitted, and then power control command cannot be normally received.

See Fig. 2, the transmission method of the power control command for network side that the embodiment of the present invention provides, comprise the following steps:
Step 20: network side determines the terminal needing to receive the power control command of multicast；
Step 21: network side transmits the power control command of the multicast to terminal on one or more frequencies.
In step 21, network side transmits the power control command of the multicast to terminal on specific frequency, or, the data transmission frequency in terminal uploads the power control command of the defeated multicast to this terminal.
Concrete, network side can transmit the power control command of the multicast to terminal according to the time cycle set on specific frequency.
Further, before network side transmits the power control command of the multicast of terminal on specific frequency, by high-level signaling, the information of this time cycle and/or the time location of the power control command sending multicast within the time cycle is sent to terminal, to enable the terminals to know the time resource at reception power control command place according to this information.It is of course also possible to be network side and terminal is made an appointment this time cycle and/or send the time location of power control command of multicast within the time cycle.
Further, before network side transmits the power control command of the multicast of terminal on specific frequency, if the data transmission frequency of this terminal is not specific frequency, then by high-level signaling, time span T is sent to this terminal, so that this terminal relative power control command delivery time T time in advance jumps back to specific frequency and receives the power control command of multicast.It is of course also possible to be that network side and terminal are made an appointment the size of T.

Further, when the transmission of network side that terminal determines is specific frequency to the frequency at the power control command place of the multicast of this terminal, if the data transmission frequency of this terminal is not specific frequency, then needs relative power control command delivery time T time in advance to jump back to specific frequency and receive the power control command of multicast.
Concrete, before terminal receives the power control command of the multicast of this terminal on specific frequency, time span T that network side is sent can be received by high-level signaling.It is of course also possible to be that terminal and network side are made an appointment the size of T.
