Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of transmission method and equipment of power control command.
Background technology
Technology of Internet of things is in the ascendant, 3-G (Generation Three mobile communication system) with and long evolving system (Long Term Evolution, LTE) in need to support machine type communication (Machine Type Communications, MTC) function.
Machinery compartment (M2M, Machine-to-machine) communication is as a kind of novel communication theory, its objective is the communication technology of number of different types is organically combined, as: machine is to machine communication, apparatus control communication, man-machine interaction communication, mobile interconnected communication, thus the development of promotion social production and life style.The business of future Human To Human communication may only account for 1/3 of whole terminal market, and the communication of larger quantity is machinery compartment (little bandwidth system) communication service.
Current mobile communications network designs for interpersonal communication, as determining of: network capacity etc.If wished, utilize mobile communications network to support the wide system communication of small band just need to the mechanism of mobile communication system, be optimized according to the feature of the wide system communication of small band, to can in the situation that traditional person to person communication is not subject to or is subject to less impact, realize better the wide system communication of small band.
Some characteristics that the current MTC recognizing may exist have: MTC terminal has Hypomobility; The time that MTC terminal and network side carry out transfer of data is controlled, and MTC terminal can only access within the time period of network appointment; The transfer of data that MTC terminal and network side carry out is not high to requirement of real-time to transfer of data, has time tolerance that is:; MTC terminal energy constraint, requires extremely low power consumption; Between MTC terminal and network side, only carry out the communication of small data quantity; MTC terminal can Yi Zuwei unit manage; Etc..
An actual MTC terminal can have above-mentioned one or more characteristics.
In order to support a large amount of MTC terminals to carry out transfer of data simultaneously, a kind of scheme is the data field in LTE system works bandwidth, configures a plurality of small band wideband points, configures respectively a part of MTC terminal and carries out transfer of data, as shown in Figure 1 in each small band wideband point.
In LTE system, main by the DCI with Downlink Control Information (DCI) form 3 and 3A on Physical Downlink Control Channel (PDCCH), indicate Physical Uplink Control Channel (the Physical Uplink Control Channel of one group of terminal (UE), PUCCH) or Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) power is controlled (Transmission Power Control, TPC) order, the power that wherein corresponding relation of UE and TPC order is configured by high level is controlled sign (TPC-Index) indication, the main distinction of DCI form 3 and 3A is that the bit number of TPC order is different, in DCI form 3, the bit number of each TPC order is 2 bits, in DCI form 3, the bit number of each TPC order is 1 bit, its circulation cyclic redundancy check (CRC) code (CRC) is to control Radio Network Temporary Identifier (Radio Network Temporary Identifier by power, TPC-RNTI) scrambling.DCI form 3, for transmitting the TPC order of PUCCH and PUSCH, is used dibit to carry out power adjustment.
In DCI form 3, its information field structure is as follows:
TPC order 1, TPC order 2 ..., TPC order N;
Wherein,
and L
format 0the size of the information bit of DCI form 0, comprising the filling bit in DCI form 0.If
in DCI form 3, fill 1 bit.
In DCI form 3A, its information field structure is as follows:
TPC order 1, TPC order 2 ..., TPC order M;
Wherein, M=L
format 0, and L
format 0the size of the information bit of DCI form 0, comprising the filling bit in DCI form 0.
To sum up, in existing LTE standard, the power control command of multicast is DCI form 3 by PDCCH or 3A transmission.Because the LTE UE in existing standard has the data receiver ability that is not less than system works bandwidth, so, PDCCH any position terminal in system bandwidth no matter, all there is not the difficulty of reception in existing terminal, and the in the situation that of a plurality of small band wideband point configuration, the semi-persistent scheduling service of great amount of terminals may transmit on some frequencies, also can on a plurality of frequencies, transmit, for the semi-persistent scheduling service of the terminal on a plurality of small band wideband points, in standard, also do not stipulate how the power control command of multicast in above-mentioned situation transmits at present.If without relevant regulations, may cause little bandwidth terminals cannot know how the power control command of its multicast form transmits, and then normal received power control command.

When definite network side transmission is specific frequency to the frequency at the power control command place of the multicast of this terminal, if the transfer of data frequency of this terminal is not specific frequency, relative power control command delivery time shifts to an earlier date the T time and jumps back to the power control command of specific frequency receiving group.
33. terminals as claimed in claim 32, is characterized in that, described power control commands receiving element also for:
On specific frequency, receive before the power control command of the multicast of this terminal, receive the time span T that network side sends by high-level signaling.
34. as the terminal as described in arbitrary in claim 28-33, it is characterized in that, described frequency determining unit is used for:
According to the agreement with network side, determine the frequency of network side transmission to the power control command place of the multicast of this terminal; Or,
The information of the frequency that the power control command of the transport multicast that reception network side sends by signaling is used, determines the frequency of network side transmission to the power control command place of the multicast of this terminal according to this information.
