Fig. 1 is the flow chart of channel indicating means embodiment one provided in an embodiment of the present invention, and the executive agent of this method embodiment is network side equipment, specifically, can be RNC or NB, but not limited to this, this present invention is not construed as limiting.
As shown in figure 1, this method embodiment, it is rapid that Bao includes Ru Xia Walk：
Walk rapid 101, network side equipment, in the N number of down channel resources for distributing to UE from network side equipment, the one of down channel for determining N number of down channel is the first down channel resources that the UE is intercepted, and wherein N is the positive integer more than or equal to 2.
Wherein, above-mentioned down channel can be DPCCH or F-DPCH, and above-mentioned N number of down channel includes the down channel that at least one shares with other UE, and the UE and other UE intercept shared down channel in different time-gap.Above-mentioned UE can support to strengthen the format detection technology in TDM scheduling, network side can according to can with down channel resources sum, at least two down channels are allocated in advance to each UE, preferably, N number of down channel resources of identical quantity can be pre-configured with to each UE, N can use down channel resources sum no more than network side equipment.
If network side equipment can be 2 with the quantity of down channel resources, each time slot only allows 2 UE to carry out transmitting uplink data, the two down channel resources are identified with dchO and dchl marks respectively, if there are 100 UE under the network side equipment, this 100 UE are given to distribute this 2 down channel resources, i.e., 100 UE share 2 down channel resources, for supporting the UE of format detection, same time slot can have 2 target UE to be activated.After target UE0 is activated, network side equipment can determine that currently is intercepting dchO or dchl with the presence or absence of other UE, the down channel resources that can be intercepted as target UE0 current time slots using the down channel chO or chl for determining not intercepted by other UE, i.e. the first down channel.
Walk rapid 102, network side equipment send channel indicating information to UE, and the channel indicating information determines the first down channel resources for UE, and frame listens the first down channel； Walk rapid 103 or, N number of down channel resources that network side equipment distributes to user equipment (UE) include giving tacit consent to down channel resources, giving tacit consent to down channel resources is used for when network side equipment does not send channel indicating information, and UE directly intercepts acquiescence down channel resources.
In Jin mono- Walk Di , Walk rapid 102, network side equipment sends channel indicating information to UE, including：Network side equipment passes through physical layer signaling Bearer Channel configured information；
Network side equipment sends the physical layer signaling of Bearer Channel configured information to UE.
Wherein, above-mentioned physical layer signaling can be specially one kind in following physical layer signalings： E-AGCH、 E-RGCH、 E-HICH、 HS-SCCH.Above-mentioned physical layer signaling can either index the temporal information that the mode added up or physical layer signaling are sent, to indicate the first down channel resources by way of index directly maps.
Jin mono- Walk, this method embodiment, in addition to：
Network side equipment sends the first signaling to UE, is that UE distributes N number of down channel resources by the first signaling.
Wherein, above-mentioned acquiescence down channel resources are that network side equipment is UE predefined；
Or, above-mentioned acquiescence down channel resources are that network side equipment sends what the second signaling was indicated to UE.Preferably, this method embodiment Walk rapid 102, in addition to：Whether judge the first down channel is acquiescence down channel；If so, it is rapid not perform transmission channel indicating information Walk then.The code resource overhead of channel indicating information is reduced by giving tacit consent to down channel Ke Yi Jin mono- Walk.
Specifically, for specific carriers, network side equipment configures at least two down channel resources to UE in advance, including acquiescence down channel, the down channel resources can be DPCCH or F-DPCH, and other UE can be configured to including at least one down channel resources in the down channel resources configured to current UE, shared down channel resources can be intercepted in different time-gap for the UE and other UE.
Before UE initiates uplink, network side equipment determine UE the first down channel that current time slots can be intercepted in pre-assigned down channel resources, channel indication message is generated according to the first down channel, and send the channel indicating information to UE, so that UE determines the first down channel according to channel indication message, and intercept first down channel.Preferably, however, it is determined that the first down channel for acquiescence down channel, then can not to UE send channel indicating information, now, UE can directly intercept acquiescence down channel resources when not receiving channel indicating information.
Can be dchO and dchl, network side with down channel resources by taking N=2 as an example when implementing The first signaling is sent to UE, wireless heterogeneous networks (Radio Resource Control, abbreviation that first signaling is issued by network side：RRC) signaling bear, it is dchO and dchl to indicate the down channel resources for distributing to UE, it is acquiescence down channel that dchO, which can wherein be predefined, or send the second signaling to UE, RRC signaling that second signaling can be issued by network side or physical layer signaling are carried, and it is acquiescence down channel to indicate dchO.If it is determined that the first down channel is dchl, non-default down channel, network side can be E-AGCH, E-RGCH, E-HICH or HS-SCCH one of bit by physical layer signaling or instruct to carry the channel indicating information that the first down channel is dchl, and send the channel indicating information in corresponding physical channel.
For E-AGCH, typically, by Absolute Grant Scope bits come Bearer Channel configured information, indicate the mode of resource number can directly be mapped using index by the way of or the mode that adds up of index.When by the way of directly being mapped using index, possible implementation is designated Absolute Grant Scopes 1 or Absolute Grant Scope=0 for the determination dchl corresponding physical layer signaling of channel indicating information;When by the way of cumulative using index, it is possible to be achieved in that Absolute Grant Scope=0 means+1 or -1 on current resource number, this present invention is not construed as limiting, so that UE determines that dchl is the first down channel by obtaining the value of Absolute Grant Scope bits when receiving E-AGCH, and intercept dchl.
For E-RGCH and E-HICH, E-RGCH and E-HICH carry 1 bit information, it is similar, can using the value of 1 bit come Bearer Channel configured information, indicate the mode of resource number can directly be mapped using index by the way of or the mode that adds up of index.When by the way of directly being mapped using index, the information that the corresponding physical layer signaling of channel indicating information that possible implementation is determination dchl is designated E-RGCH and E-HICH carryings is 1 or -1;When by the way of cumulative using index, the possible information for being achieved in that E-RGCH and E-HICH carryings means+1 on current resource number for 1, the information of E-RGCH and E-HICH carryings means -1 on current resource number for -1, this present invention is not construed as limiting, so that determining that dchl is the first down channel when UE receives E-RGCH or E-HICH by obtaining the information of carrying, and intercept dchl.
For HS-SCCH, HS-SCCH order Bearer Channel configured informations can be used, either indexed by the way of indicating the mode of resource number and can directly being mapped using index cumulative mode or, can also be using the temporal information of HS-SCCH order transmissions come implicit instruction.By the way of index directly maps, possible implementation is to carry out explicit instruction channel resource to number using HS-SCCH orderl to be 1;By the way of index is cumulative, possible implementation is that HS-SCCH order 1 mean in current resource + 1 or HS-SCCH order2 mean -1 on current resource number in numbering;When the temporal information sent using HS-SCCH order is come implicit instruction, possible implementation is System Frame Number (the System Frame Number, abbreviation included according to the HS-SCCH order corresponding subframe numbers of transmission frame：SFN) and Connection Frame Number (Connection Frame Number, referred to as：CFN) modulus（Mod) dchl is identified, such as HS-SCCH order meet in subframe numbers（SFN+5*CFN) mod 2=0 subframe sends then meaning and uses dchl, so that by being calculated accordingly after obtaining HS-SCCH order or acquisition HS-SCCH order subframe numbers when UE receives HS-SCCH, to determine the first down channel.
It should be noted that, for N=4, or other any values, its channel instruction implementation method is similar, is specifically repeated no more.
UE for supporting format detection, the UE can terminate other UE transmission when transmitting, this will cause the limited amount of the UE simultaneous transmissions of same moment support format detection, typically, the number of format detection E-AGCH in cell can be equal to, this causes different UE to share down channel resources.The E-AGCH of the format detection configured in such as cell number is 3, and support that the UE numbers of format detection are 100, in the prior art, common network side needs relative set at least 100 down channel resources DPCCH or F-DPCH, but same time slot only has 3 UE and can carry out transmitting uplink data, therefore real network side needs the DPCCH/F-DPCH resources of configuration to be 3 altogether, 3 down channel resources can be configured to 100 UE, and before UE sends upstream data, channel indicating information is sent to indicate down channel that UE current time slots can be intercepted, so as to greatly save down channel DPCCH or F-DPCH resource.
It is worth noting that, the down channel resources in the channel indicating means that the present embodiment is provided share the situation that network side can be 1 with the quantity of down channel resources that is also applied for.Now, each time slot only allows 1 UE to carry out transmitting uplink data, the down channel resources are identified with dchO, if there is 100 UE under the network side, this 100 UE are then given to distribute this down channel resources, gp, 100 UE share this down channel resources, for supporting the UE of format detection, same time slot, only 1 target UE is activated, after target UE activation, other 99 UE are deactivated, namely target UE can directly intercept the down channel resources, to adjust E-DCH transmit power according to the down channel resources, realize that high speed data rate is transmitted, can monitors downlink channel resource and to send channel indication message Walk rapid without performing that network side determines.
This method embodiment, multiple down channel resources are distributed by network side equipment to UE, and are sent channel indicating information to UE or given tacit consent to down channel resources for UE distribution, so that UE is according to channel Configured information monitors downlink channel directly intercepts acquiescence down channel resources, so that the down channel resources of network side can be shared between different UE, solve a large amount of UE it is online when, the problem of down channel DPCCH or F-DPCH resource occupation code resource overhead are too high, and by sharing down channel resources, down channel resources expense is saved, the utilization rate of down channel resources is improved.
