Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The present invention has provided the communication means of wide-band terminal under a kind of discrete spectrum system.Next specific implementation of the present invention is described in detail.
Method of the present invention can be supported the discrete spectrum communication system of multiple technologies: such as orthogonal frequency division multiplexi (OFDM, Orthogonal Frequency Division Multiplexing) communication system, frequency division multiple access (FDMA, Frequency Division Multiple Access) communication system, code division multiple access (CDMA, Code Division Multiple Access) communication system or time division multiple access (TDMA, Time Division Multiple Access) communication system.Following embodiment describes as an example of ofdm communication system example.
Among the present invention, the resident attaching process of the start of broadband UE is identical with the mode of arrowband UE in the prior art, random access procedure is afterwards also finished identical with the random access procedure of arrowband UE, mainly comprise: to the Reference Signal Received Power (RSRP of different bunches broadcast singals, Reference SignalReceiving Power) measures, and the result sorted, select RSRP best bunch carry out resident and random access.Fig. 1 is the frequency range schematic diagram of broadband of the present invention UE working range, as shown in Figure 1, comprise three bunches among this figure, each bunch comprises that arrowband and broadband UE can be resident and the frequency range (such as the nicking part 101,102 and 103 of each bunch) of work, also comprises operable frequency range when only broadband UE carries out service communication (such as the blank parts 104 in each bunch, 105 and 106).Broadband UE can select one bunch to carry out resident and random access according to preceding method, and the frequency range that access this moment is in the arrowband frequency range, i.e. nicking part 101 in each bunch, 102 and 103 described in Fig. 1.
After broadband UE accesses successfully, the process of monitoring schedule information also with present LTE communication system in the monitoring schedule information process of arrowband UE be consistent.
The communication process of aforesaid broadband UE is owing to identical with the communication process of arrowband UE, so this paper is referred to as narrow band mode or list band model.When broadband UE need to carry out business data transmission, then carry out method of the present invention, this paper is referred to as broadband mode or many subbands pattern.
Fig. 2 is a kind of flow chart of the method for the invention.Referring to Fig. 2, this flow process comprises:
In this step, when wide-band terminal need to carry out business data transmission, need initiating business request, set up radio resource control (RRC, Radio Resource Control) connects, broadband UE can report to the base station frequency point information that self supports in this process, after the base station obtains these frequency point information, distributes the broadband resource of frequency range to this broadband UE.
After step 203, wide-band terminal are received described DCI instruction, migrate to the broadband frequency range that described broadband frequency range identification information identifies from self resident frequency range.
Described business procedure specifically comprises up-downgoing scheduling and business data transmission, wherein the up-downgoing scheduling needs the control signal of transmitting-receiving to transmit in an appointment subband of described broadband frequency range separately, conciliates the reference signal of calling at all the other subband service data transmissions of this broadband frequency range.Channel in the appointment subband of described control channel comprises: Physical Control Format Indicator Channel (PCFICH), Physical Downlink Control Channel (PDCCH) and Physical Uplink Control Channel (PUCCH).In the present embodiment, the special-purpose subband of all control signals is first subband of described broadband frequency range, and other subband is exclusively used in service data transmission and conciliates the reference signal of calling.In a further embodiment, the special-purpose subband of all control signals also can be other subband of described broadband frequency range, and the reference signal that described business datum reconciliation is called other subband outside the special-purpose subband of this control signal transmits.
After described business procedure finishes, then the base station can further discharge described broadband frequency range, and stop the transmission that described solution is called reference signal, PCFICH signal, PDCCH signal and PUCCH signal, thereby allow the base station that these broadband frequency allocations are used to other broadbands UE.
In another embodiment of the present invention, in above-mentioned steps 201, after broadband UE sends service request, the base station can further judge whether to support the broadband migration of current broadband UE according to current resource situation, if support then be this broadband UE distribution broadband frequency range, and giving this broadband UE with the identification information of this broadband frequency range by the DCI transmitting signaling downwards, this broadband UE enters many subbands pattern and carries out subsequent step of the present invention; If current resource situation is not supported the broadband migration of current broadband UE, then the base station is not that this broadband UE distributes the broadband frequency range, continues to carry out the arrowband workflow, and namely broadband UE can be operated under the list band model always.
In addition, used said method of the present invention, can in a residential quarter, support simultaneously arrowband UE and broadband UE in the discrete spectrum communication system, in order to make more easily allocate resource of discrete spectrum OFDM and FDMA communication system, in a preferred embodiment of the present invention, the integral multiple that the employed fast Fourier transform of described broadband UE (FFT, Fast Fourier Transformation) is counted and counted for UE used FFT in arrowband in the same communication system.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of making, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
