Specific embodiment
Below by drawings and examples, the technical solution of the disclosure is described in further detail.
The flow chart of one embodiment of the resource multiplexing method of the disclosure is as shown in Figure 1.
In a step 101, base station divides number according to predetermined single channel and individual channel is divided into multiple subbands.Such as, single letter
Road is 100M, and predetermined single channel segmentation number is 5, then channel is divided into 5 subbands, each subband 20M.
In a step 102, determine in each subband whether include PDCCH.As shown in Fig. 2, individual channel is divided into 5 sons
Band, wherein include PDCCH in subband b, the c marked with oblique line.
In step 103, base station sends sub-band information to terminal, include in sub-band information each subband whether include
The information of PDCCH, so that terminal never includes selecting subband for downlink data transmission in the subband of PDCCH.
By such method, individual channel can be divided into multiple subbands, and identify in the subband whether include
PDCCH, so as to terminal as unit of subband never including PDCCH subband in selection subband be used for downlink data transmission, thus
Frequency resource fragmentation caused by avoiding the bandwidth of User support and channel width from mismatching wastes, and improves the utilization of frequency resource
Rate.
It in one embodiment, may include bitmap bitmap information in sub-band information, every 1 bit is one corresponding in bitmap
Subband, identifying corresponding subband by bit value every in bitmap is to include PDCCH or do not include PDCCH, and such as 1 identifies the subband packet
Include PDCCH, 0 to identify the subband do not include PDCCH.In one embodiment, new channel can be defined or use SIB
(System Information Block, system information block), group-common DCI (Downlink Control
Information, Downlink Control Information) or UE specific DCI bitmap is sent to user.
By such method, subband identities can be carried out using the bitmap for being easy to parse, improves terminal analyzing efficiency, subtracts
Few occupancy to terminal resource.
It in one embodiment, can according to the case where each channel and the bandwidth demand of terminal, PDCCH width demand
Different channels to be divided into the subband of different number, to improve the adaptive ability of system.
In one embodiment, predetermined single channel segmentation number can be determined according to PDCCH width and single channel width, it is such as single
Channel width is 100M, and PDCCH width is 20M, it is determined that predetermined single channel segmentation number is 5, to reduce the son including PDCCH
The frequency resource being wasted in band, further increases the utilization rate of downstream frequency resource.
In one embodiment, since the bandwidth of terminal needs is not identical, terminal can be according to sub-band information, frequency band
Occupancy situation and bandwidth demand never include that one or more subbands is selected to carry out downlink data biography in the idle subband of PDCCH
It is defeated.As shown in Figure 2, user 1 supports that bandwidth is 40MHz, and user 2 supports that bandwidth is also 40MHz, then son can be used in user 1
Band a carries out downlink data transmission, carries out downlink control data transmission using subband b, user 2 can be used subband c and carry out downlink
Data transmission carries out downlink control data transmission using subband d, to avoid occurring while making full use of bandwidth resources
Conflict.If in the case that resource is idle in Fig. 2, user 3 supports bandwidth 100MHz, then can be used discontinuous subband a,
C, e carries out downlink data transmission, carries out downlink control data transmission using subband b, d.
By such method, appropriate number of bandwidth can be distributed according to the bandwidth demand of user as unit of subband,
Guarantee the bandwidth demand for meeting user.
In one embodiment, in the case where user needs multiple subbands, different channels can be belonged to for user's distribution
Subband increase the number of users that network can carry to further increase the utilization rate to frequency resource.
The schematic diagram of one embodiment of the resource multiplex system of the disclosure is as shown in Figure 3.It base station 31 can be according to predetermined
Single channel divides number and individual channel is divided into multiple subbands, determines in each subband whether include PDCCH, and send son to terminal
Information, include in sub-band information each subband whether include PDCCH information.321~32n of terminal can be according to sub-band information
Never selection subband is used for downlink data transmission in the subband including PDCCH.
Individual channel can be divided into multiple subbands by such resource multiplex system, and identify in the subband whether include
PDCCH, so as to terminal as unit of subband never including PDCCH subband in selection subband be used for downlink data transmission, thus
Frequency resource fragmentation caused by avoiding the bandwidth of User support and channel width from mismatching wastes, and improves the utilization of frequency resource
Rate.
In one embodiment, whether base station 31 can include PDCCH by bitmap bitmap message identification subband.Bitmap
In the corresponding subband of every 1 bit, every bit value mark corresponding subband is to include PDCCH or do not include PDCCH in bitmap, such as
The 1 mark subband includes PDCCH, and 0 to identify the subband do not include PDCCH.
Such resource multiplex system can carry out subband identities using the bitmap for being easy to parse, and improve terminal parsing effect
Rate reduces the occupancy to terminal resource.
In one embodiment, base station can be according to the case where each channel and bandwidth demand, the PDCCH wide of terminal
Different channels can be divided into the subband of different number by degree demand, to improve the adaptive ability of system.
In one embodiment, base station can determine predetermined single channel segmentation number according to PDCCH width and single channel width,
If single channel width is 100M, PDCCH width is 20M, it is determined that predetermined single channel segmentation number is 5, so that reducing includes PDCCH
Subband in the frequency resource that is wasted, further increase the utilization rate of downstream frequency resource.
In one embodiment, since the bandwidth of terminal needs is not identical, terminal can be according to sub-band information, frequency band
Occupancy situation and bandwidth demand never include that one or more subbands is selected to carry out downlink data biography in the idle subband of PDCCH
It is defeated.As shown in Figure 2, user 1 supports that bandwidth is 40MHz, and user 2 supports that bandwidth is also 40MHz, then son can be used in user 1
Band a carries out downlink data transmission, carries out downlink control data transmission using subband b, user 2 can be used subband c and carry out downlink
Data transmission carries out downlink control data transmission using subband d, to avoid occurring while making full use of bandwidth resources
Conflict.If in the case that resource is idle in Fig. 2, user 3 supports bandwidth 100MHz, then can be used discontinuous subband a,
C, e carries out downlink data transmission, carries out downlink control data transmission using subband b, d.
Such resource multiplex system can distribute appropriate number of band according to the bandwidth demand of user as unit of subband
Width guarantees the bandwidth demand for meeting user.
In one embodiment, in the case where user needs multiple subbands, user, which can be used, belongs to different channels
Subband improves the number of users that network can carry to further increase the utilization rate to frequency resource.
