Description

信道指示方法、装置与系统技术领域 Channel indication method, device and system

本发明实施例涉及通信技术，尤其涉及一种信道指示方法、装置与系统。背景技术 The embodiments of the present invention relate to communication technologies, and in particular, to a channel indication method, apparatus, and system. Background technique

增强的时分复用 (Time Division Multiplexing, 简称： TDM)调度，是第三代合作伙伴计划 (The 3rd Generation Partnership Project, 简称： 3GPP)的最新标准 R12正在研究的上行增强 (Enhanced Uplink, 简称： EUL)进一歩增强特性 (Further EUL Enhancement)中的一个关键技术。增强的 TDM调度技术的一个主要目的是调度高速用户设备 (User Equipment, 简称： UE)，基于 TDM调度方法，为发送数据的 UE调度较高的底噪抬升 (Rise over Thermal noise, 简称： RoT)，从而使得 UE可以低时延、高速率的发送上行数据。 Enhanced Time Division Multiplexing (TDM) scheduling, is the latest standard of the 3rd Generation Partnership Project (3GPP), R12 is researching the uplink enhancement (Enhanced Uplink, referred to as: EUL) A key technology in the FUer EUL Enhancement. A main purpose of the enhanced TDM scheduling technology is to schedule a high-speed user equipment (User Equipment, referred to as UE). Based on the TDM scheduling method, a higher RISE over Thermal noise (RoT) is scheduled for the UE transmitting data. Therefore, the UE can send uplink data with low latency and high rate.

增强 TDM调度，通过格式检测 (grant detection)方案， SP UE检测网络侧设备基站（NodeB , 简称： NB)下发的增强专用信道 (Enhanced Dedicated Channel,简称： E-DCH)的绝对授权信道 (Absolute Grant Channel,简称： AGCH) (E-DCH AGCH, 简称： E-AGCH), 如果 UE检测到网络下发了 E-AGCH, 且该 E-AGCH是发给该 UE的，即便用该用户的 RNTI解扰通过，则 UE根据该 E-AGCH发送数据，如果 UE检测到网络下发了 E-AGCH且该 E-AGCH 不是发给该 UE的，即便用该用户的 RNTI解扰通过，则 UE停止发送上行数据。格式检测方案通过 E-AGCH既起到了激活目标 UE，同时起到了去激活其它 UE的目的，节省了上行码资源信令，可支持大量的在线 UE。 Enhanced TDM scheduling, the SP UE detects the absolute authorized channel of the Enhanced Dedicated Channel (E-DCH) delivered by the network-side device base station (NodeB, NB for short) through the grant detection scheme (Absolute) Grant Channel (referred to as: AGCH) (E-DCH AGCH, E-AGCH for short), if the UE detects that the E-AGCH is sent by the network, and the E-AGCH is sent to the UE, even if the RNTI of the user is used. After the descrambling is passed, the UE sends data according to the E-AGCH. If the UE detects that the E-AGCH is sent by the network and the E-AGCH is not sent to the UE, the UE stops even if the RNTI of the user is descrambled. Send upstream data. The format detection scheme not only activates the target UE through E-AGCH, but also deactivates other UEs, saves uplink code resource signaling, and supports a large number of online UEs.

通常地，网络侧设备，如无线网络控制器 (Radio Network Controller, 简称： RNC)或基站，为每个在线 UE配置一个下行物理信道资源，如专用物理控制信道 (Dedicated Physical Control Channel，简称： DPCCH)或者部分专用物理信道 (Fractional-Dedicated Physical Channel, 简称： F-DPCH), 使得 UE在收到上行授权后，根据监听到的下行 DPCCH或者 F-DPCH来调整上行信道的发送功率。然而上述增强 TDM 调度技术，使得网络侧设备需要为大量的在线 UE分配下行 DPCCH或者 F-DPCH资源，容易导致 DPCCH或者 F-DPCH 资源占用码资源开销过高的问题。发明内容 Generally, a network-side device, such as a radio network controller (RNC) or a base station, configures one downlink physical channel resource for each online UE, such as a dedicated physical control channel (DPCCH). The Fractal-Dedicated Physical Channel (F-DPCH) is used to adjust the transmit power of the uplink channel according to the monitored downlink DPCCH or F-DPCH after receiving the uplink grant. However, the enhanced TDM scheduling technology described above requires the network side device to allocate downlink DPCCH or F-DPCH resources for a large number of online UEs, which may easily lead to DPCCH or F-DPCH. The resource occupancy code resource overhead is too high. Summary of the invention

图 1为本发明实施例提供的信道指示方法实施例一的流程图，该方法实施例的执行主体为网络侧设备，具体的，可以为 RNC或者 NB，但不限于此，对此本发明不作限定。 FIG. 1 is a flowchart of Embodiment 1 of a channel indication method according to an embodiment of the present invention. The implementation body of the method embodiment is a network side device, and specifically, may be an RNC or an NB, but is not limited thereto, and the present invention does not limited.

如图 1所示，本方法实施例，包括如下歩骤： As shown in FIG. 1 , the method embodiment includes the following steps:

歩骤 101、网络侧设备，从网络侧设备分配给 UE的 N个下行信道资源中，确定该 N个下行信道的其中一个下行信道为该 UE侦听的第一下行信道资源，其中 N为大于等于 2的正整数。 Step 101: The network side device determines, according to the N downlink channel resources allocated to the UE by the network side device, that one of the downlink channels of the N downlink channels is the first downlink channel resource that the UE listens, where N is A positive integer greater than or equal to 2.

其中，上述下行信道可以是 DPCCH或者 F-DPCH, 并且上述 N个下行信道包括至少一个与其他 UE共享的下行信道，该 UE与其他 UE在不同时隙侦听共享的下行信道。上述 UE可支持增强 TDM调度中的格式检测技术，网络侧可以根据可用下行信道资源总数，给每个 UE预先分配至少两个下行信道，优选地，可以给每个 UE均预先配置相同数量的 N个下行信道资源， N 不超过网络侧设备可用下行信道资源总数。 The downlink channel may be a DPCCH or an F-DPCH, and the N downlink channels include at least one downlink channel shared with other UEs, and the UE and other UEs listen to the shared downlink channel in different time slots. The foregoing UE may support the format detection technology in the enhanced TDM scheduling, and the network side may pre-allocate at least two downlink channels to each UE according to the total number of available downlink channel resources. Preferably, each UE may be pre-configured with the same number of Ns. The downlink channel resources, N does not exceed the total number of downlink channel resources available to the network side device.

若网络侧设备可用下行信道资源的数量为 2，每个时隙仅允许 2个 UE进行上行数据传输，以 dchO和 dchl标识分别标识这两个下行信道资源，若该网络侧设备下有 100个 UE,给这 100个 UE均分配这 2个下行信道资源，即， 100个 UE共享 2个下行信道资源，对于支持格式检测的 UE来说，同一时隙，可有 2个目标 UE被激活。目标 UE0被激活后，网络侧设备可确定当前是否存在其他 UE在侦听 dchO或 dchl，以确定未被其他 UE侦听的下行信道 chO 或 chl为目标 UE0当前时隙可侦听的下行信道资源，即第一下行信道。 If the number of downlink channel resources available on the network side device is 2, only two UEs are allowed to perform uplink data transmission in each time slot, and the two downlink channel resources are respectively identified by the dchO and dchl identifiers, if there are 100 downlink network devices. The UE allocates the two downlink channel resources to the 100 UEs, that is, 100 UEs share two downlink channel resources. For the UE supporting the format detection, two target UEs may be activated in the same time slot. After the target UE0 is activated, the network side device may determine whether other UEs are currently listening to dchO or dchl to determine that the downlink channel chO or chl that is not intercepted by other UEs is the downlink channel resource that the target UE0 can listen to in the current time slot. , that is, the first downlink channel.

歩骤 102、网络侧设备向 UE发送信道指示信息，该信道指示信息用于 UE确定第一下行信道资源，并帧听第一下行信道；歩骤 103、或者，网络侧设备分配给用户设备 UE的 N个下行信道资源中包括默认下行信道资源，默认下行信道资源用于在网络侧设备不发送信道指示信息时， UE直接侦听默认下行信道资源。 Step 102: The network side device sends, to the UE, channel indication information, where the channel indication information is used by the UE to determine the first downlink channel resource, and the frame listens to the first downlink channel. Step 103: Or, the N downlink channel resources allocated by the network side device to the user equipment UE include a default downlink channel resource, where the default downlink channel resource is used to directly listen to the default downlink when the network side device does not send the channel indication information. Channel resources.

进一歩地，歩骤 102中，网络侧设备向 UE发送信道指示信息，包括：网络侧设备通过物理层信令承载信道指示信息； Further, in step 102, the network side device sends the channel indication information to the UE, where the network side device carries the channel indication information through the physical layer signaling;

网络侧设备向 UE发送承载信道指示信息的物理层信令。 The network side device sends physical layer signaling carrying the channel indication information to the UE.

其中，上述物理层信令可以具体为下述物理层信令中的一种： E-AGCH、 E-RGCH、 E-HICH、 HS-SCCH。上述物理层信令可通过索引直接映射的方式，或者索引累加的方式，或者物理层信令发送的时间信息，来指示第一下行信道资源。 The physical layer signaling may be specifically one of the following physical layer signaling: E-AGCH, E-RGCH, E-HICH, HS-SCCH. The foregoing physical layer signaling may indicate the first downlink channel resource by using an index direct mapping manner, or an index accumulation manner, or time information sent by the physical layer signaling.

进一歩地，该方法实施例，还包括： Further, the method embodiment further includes:

网络侧设备向 UE发送第一信令，通过第一信令为 UE分配 N个下行信道资源。 The network side device sends the first signaling to the UE, and allocates N downlink channel resources to the UE by using the first signaling.

其中，上述默认下行信道资源为网络侧设备为 UE预定义的； The default downlink channel resource is predefined by the network side device for the UE;

或者，上述默认下行信道资源为网络侧设备向 UE发送第二信令指示的。优选地，该方法实施例在歩骤 102，还包括：判断第一下行信道是否为默认下行信道；若是，则不执行发送信道指示信息的歩骤。通过默认下行信道可以进一歩减少信道指示信息的码资源开销。 Alternatively, the foregoing default downlink channel resource is that the network side device sends the second signaling indication to the UE. Preferably, the method embodiment, in step 102, further includes: determining whether the first downlink channel is a default downlink channel; if yes, performing a step of transmitting channel indication information. The code resource overhead of the channel indication information can be further reduced by the default downlink channel.

具体来说，对于特定载波，网络侧设备预先给 UE配置至少两个下行信道资源，其中包括默认下行信道，该下行信道资源可以为 DPCCH 或者 F-DPCH, 并且给当前 UE配置的下行信道资源中可以包括至少一个下行信道资源被配置给其他 UE，对于该 UE和其他 UE可在不同时隙侦听共享的下行信道资源。 Specifically, for a specific carrier, the network side device allocates at least two downlink channel resources to the UE in advance, including a default downlink channel, where the downlink channel resource may be a DPCCH or an F-DPCH, and is configured in a downlink channel resource configured by the current UE. At least one downlink channel resource may be configured to be allocated to other UEs, and the shared downlink channel resources may be listened to in different time slots for the UE and other UEs.

在 UE发起上行传输之前，网络侧设备确定 UE所预先分配的下行信道资源中当前时隙可侦听的第一下行信道，根据第一下行信道生成信道指示消息，并向 UE发送该信道指示信息，以使 UE根据信道指示消息确定第一下行信道，并侦听该第一下行信道。优选地，若确定的第一下行信道为默认下行信道，则可以不向 UE发送信道指示信息，此时， UE在未接收到信道指示信息时，可以直接侦听默认下行信道资源。 Before the UE initiates the uplink transmission, the network side device determines a first downlink channel that can be intercepted by the current time slot in the downlink channel resource allocated by the UE, generates a channel indication message according to the first downlink channel, and sends the channel to the UE. And indicating information, so that the UE determines the first downlink channel according to the channel indication message, and listens to the first downlink channel. Preferably, if the determined first downlink channel is the default downlink channel, the channel indication information may not be sent to the UE. At this time, the UE may directly listen to the default downlink channel resource when the channel indication information is not received.

具体实现时，以 N=2为例，可用下行信道资源为 dchO和 dchl , 网络侧向 UE 发送第一信令，所述第一信令由网络侧下发的无线资源控制 (Radio Resource Control, 简称： RRC)信令承载，指示分配给 UE的下行信道资源为 dchO和 dchl ,其中可预定义 dchO为默认下行信道，或者向 UE发送第二信令，所述第二信令可由网络侧下发的 RRC信令或者物理层信令来承载，指示 dchO 为默认下行信道。若确定第一下行信道为 dchl , 非默认下行信道，网络侧可通过物理层信令为 E-AGCH、 E-RGCH、 E-HICH、或者 HS-SCCH的其中一个比特或者指令来承载第一下行信道为 dchl的信道指示信息，并在相应的物理信道发送该信道指示信息。 For specific implementation, take N=2 as an example, and the available downlink channel resources are dchO and dchl, and the network side Transmitting the first signaling to the UE, where the first signaling is carried by a radio resource control (Radio Resource Control, RRC) signaling, which is sent by the network, and indicates that the downlink channel resources allocated to the UE are dchO and dchl, where The dchO may be a default downlink channel, or the second signaling may be sent to the UE, where the second signaling may be carried by RRC signaling or physical layer signaling delivered by the network, indicating that dchO is the default downlink channel. If it is determined that the first downlink channel is dchl, the non-default downlink channel, the network side may carry the first one of the E-AGCH, the E-RGCH, the E-HICH, or the HS-SCCH by using physical layer signaling. The downlink channel is channel indication information of dchl, and the channel indication information is sent on the corresponding physical channel.

对于 E-AGCH, 典型地，通过 Absolute Grant Scope比特来承载信道指示信息，指示资源编号的方式可以采用索引直接映射的方式或者索引累加的方式。当采用索引直接映射的方式时，可能的实现方式为确定 dchl的信道指示信息对应的物理层信令标识为 Absolute Grant Scopes 1 或者 Absolute Grant Scope=0; 当采用索引累加的方式时，可能的实现方式是 Absolute Grant Scope = 0意味着在当前的资源编号上 +1或 -1，对此本发明不作限定，使得 UE接收 E-AGCH时通过获取 Absolute Grant Scope比特的值来确定 dchl为第一下行信道，并侦听 dchl。 For the E-AGCH, the channel indication information is typically carried by the Absolute Grant Scope bit, and the manner of indicating the resource number may be an index direct mapping manner or an index accumulation manner. When the index direct mapping mode is adopted, the possible implementation manner is to determine the physical layer signaling identifier corresponding to the channel indication information of dchl as Absolute Grant Scopes 1 or Absolute Grant Scope=0; when the index accumulation method is adopted, the possible implementation is implemented. The method is that Absolute Grant Scope = 0 means +1 or -1 on the current resource number. The present invention is not limited, so that when the UE receives the E-AGCH, the value of the Absolute Grant Scope bit is obtained to determine that dchl is the first one. Line channel, and listen to dchl.

对于 E-RGCH和 E-HICH, E-RGCH和 E-HICH均承载 1个比特信息，类似的，可以采用该 1个比特的值来承载信道指示信息，指示资源编号的方式可以采用索引直接映射的方式或者索引累加的方式。当采用索引直接映射的方式时，可能的实现方式为确定 dchl的信道指示信息对应的物理层信令标识为 E-RGCH和 E-HICH承载的信息为 1或者 -1 ; 当采用索引累加的方式时，可能的实现方式是 E-RGCH和 E-HICH承载的信息为 1意味着在当前的资源编号上 +1， E-RGCH和 E-HICH承载的信息为 -1意味着在当前的资源编号上 -1，对此本发明不作限定，使得 UE接收 E-RGCH或 E-HICH时通过获取承载的信息来确定 dchl为第一下行信道，并侦听 dchl。 For E-RGCH and E-HICH, both E-RGCH and E-HICH carry 1 bit information. Similarly, the value of the 1 bit can be used to carry channel indication information, and the manner of indicating the resource number can be directly mapped by index. The way or the way the index is accumulated. When the index direct mapping mode is adopted, the possible implementation manner is to determine that the physical layer signaling identifier corresponding to the channel indication information of dchl is E-RGCH and the information carried by the E-HICH is 1 or -1; The possible implementation manner is that the information carried by the E-RGCH and the E-HICH is 1 means that the current resource number is +1, and the information carried by the E-RGCH and the E-HICH is -1 means the current resource number. The above-mentioned invention is not limited. When the UE receives the E-RGCH or the E-HICH, the UE determines that dchl is the first downlink channel and listens to dchl by acquiring the information of the bearer.

对于 HS-SCCH, 可采用 HS-SCCH order承载信道指示信息，指示资源编号的方式可以采用索引直接映射的方式或者索引累加的方式，或者，还可以采用 HS-SCCH order发送的时间信息来隐式指示。采用索引直接映射的方式，可能的实现方式为使用 HS-SCCH orderl来显式指示信道资源编号为 1 ; 采用索引累加的方式，可能的实现方式为 HS-SCCH order 1意味着在当前的资源编号上 +1或者 HS-SCCH order2意味着在当前的资源编号上 -1 ;采用 HS-SCCH order发送的时间信息来隐式指示时，可能的实现方式为根据 HS-SCCH order 的发送帧对应的子帧号包括的系统帧号 (System Frame Number, 简称： SFN) 和连接帧号 (Connection Frame Number, 简称： CFN)取模（mod)来标识 dchl，如 HS-SCCH order在子帧号满足（SFN+5*CFN) mod 2 =0的子帧发送则意味使用 dchl , 使得 UE接收 HS-SCCH时通过获取 HS-SCCH order或者获取 HS-SCCH order子帧号后进行相应的计算，来确定第一下行信道。 For the HS-SCCH, the HS-SCCH order bearer channel indication information may be used, and the manner of indicating the resource number may be an index direct mapping manner or an index accumulation manner, or may be implicitly using the time information sent by the HS-SCCH order. Instructions. The direct mapping method is adopted. The possible implementation method is to use HS-SCCH order1 to explicitly indicate the channel resource number is 1; the index accumulation method is adopted, and the possible implementation mode is HS-SCCH order 1 means the current resource. The number above +1 or HS-SCCH order2 means that the current resource number is -1; when the time information transmitted by the HS-SCCH order is implicitly indicated, the possible implementation is corresponding to the transmission frame according to the HS-SCCH order. The system frame number (System Design Number: SFN) and the Connection Frame Number (CFN) modulo (mod) of the subframe number are used to identify dchl, such as the HS-SCCH order is satisfied in the subframe number ( SFN+5*CFN) mod 2 =0 subframe transmission means that dchl is used, so that when the UE receives the HS-SCCH, it acquires the HS-SCCH order or obtains the HS-SCCH order subframe number and then performs corresponding calculation to determine the first A downlink channel.

需说明的是，对于 N=4，或者任意其他取值，其信道指示实现方法是类似的，具体不再赘述。 It should be noted that, for N=4, or any other value, the channel indication implementation method is similar, and details are not described herein.

对于支持格式检测的 UE，该 UE传输时会终止其它 UE的传输，这将导致同一个时刻支持格式检测的 UE 同时传输的数量有限，典型地，可以等于小区内格式检测 E-AGCH的数目，这使得不同 UE可共享下行信道资源。比如小区中配置的格式检测的 E-AGCH的数目为 3，而支持格式检测的 UE数目为 100，现有技术中，通常的网络侧需要相应设置至少 100个下行信道资源 DPCCH或者 F-DPCH, 然而同一时隙仅有 3个 UE可进行上行数据传输，因此实际网络侧总共需要配置的 DPCCH/F-DPCH资源为 3个，可给 100个 UE均配置 3个下行信道资源，并在 UE发送上行数据之前，发送信道指示信息以指示 UE 当前时隙可侦听的下行信道，从而可以大大节省下行信道 DPCCH或 F-DPCH资源。 For a UE that supports format detection, the UE will terminate the transmission of other UEs when transmitting, which will result in a limited number of simultaneous transmissions of the UE supporting the format detection at the same time. Typically, the number of E-AGCHs can be detected in the intra-cell format. This allows different UEs to share downlink channel resources. For example, the number of E-AGCHs in the format detected by the cell is 3, and the number of UEs supporting the format detection is 100. In the prior art, the network side needs to set at least 100 downlink channel resources DPCCH or F-DPCH. However, only three UEs in the same time slot can perform uplink data transmission. Therefore, the total number of DPCCH/F-DPCH resources to be configured on the actual network side is three, and three downlink channel resources can be configured for 100 UEs, and are sent in the UE. Before the uplink data, the channel indication information is sent to indicate the downlink channel that the UE can listen to in the current time slot, so that the downlink channel DPCCH or F-DPCH resources can be greatly saved.

值得注意的是，本实施例提供的信道指示方法中的下行信道资源共享也适用于网络侧可用下行信道资源的数量为 1 的情况。此时，每个时隙仅允许 1个 UE进行上行数据传输，以 dchO标识该下行信道资源，若该网络侧下有 100个 UE，则给这 100个 UE均分配这个下行信道资源， gp， 100个 UE共享这一个下行信道资源，对于支持格式检测的 UE来说，同一时隙，只有 1 个目标 UE被激活，目标 UE激活后，其他 99个 UE被去激活，也即目标 UE 可直接侦听该下行信道资源，以根据该下行信道资源调整 E-DCH 的发送功率，实现高速数据率传输，而不需要执行网络侧确定可侦听下行信道资源以及发送信道指示消息的歩骤。 It should be noted that the downlink channel resource sharing in the channel indication method provided by this embodiment is also applicable to the case where the number of available downlink channel resources on the network side is 1. At this time, only one UE is allowed to perform uplink data transmission in each time slot, and the downlink channel resource is identified by dchO. If there are 100 UEs on the network side, the downlink channel resources, gp, are allocated to the 100 UEs. 100 UEs share this one downlink channel resource. For a UE supporting format detection, only one target UE is activated in the same time slot. After the target UE is activated, the other 99 UEs are deactivated, that is, the target UE can directly The downlink channel resource is monitored to adjust the transmit power of the E-DCH according to the downlink channel resource to implement high-speed data rate transmission, and the network side does not need to perform the step of determining that the downlink channel resource can be intercepted and the channel indication message is sent.

该方法实施例，通过网络侧设备给 UE分配多个下行信道资源，并且向 UE发送信道指示信息或者为 UE分配默认下行信道资源，以使 UE根据信道指示信息侦听下行信道或者直接侦听默认下行信道资源，使得网络侧的下行信道资源可在不同 UE之间共享，解决了大量 UE在线时，下行信道 DPCCH 或者 F-DPCH资源占用码资源开销过高的问题，并且通过共享下行信道资源，节省了下行信道资源开销，提高了下行信道资源的利用率。 In this embodiment, the UE allocates multiple downlink channel resources to the UE by using the network side device, and sends channel indication information to the UE or allocates a default downlink channel resource to the UE, so that the UE according to the channel The indication information intercepts the downlink channel or directly listens to the default downlink channel resource, so that the downlink channel resource of the network side can be shared between different UEs. When a large number of UEs are online, the downlink channel DPCCH or the F-DPCH resource occupation code resource overhead is over The problem is high, and by sharing the downlink channel resources, the downlink channel resource overhead is saved, and the utilization of the downlink channel resources is improved.

图 2为本发明实施例提供的信道指示方法实施例二的流程图，该方法实施例的执行主体为 UE，与图 1所示方法实施例对应，如图 2所示，该方法实施例包括如下歩骤： FIG. 2 is a flowchart of Embodiment 2 of a channel indication method according to an embodiment of the present invention. The implementation body of the method embodiment is a UE, which corresponds to the method embodiment shown in FIG. 1. As shown in FIG. 2, the method embodiment includes The following steps:

歩骤 201、 UE接收网络侧设备发送的信道指示信息，该信道指示信息用于 UE确定第一下行信道资源，并帧听第一下行信道； Step 201: The UE receives channel indication information sent by the network side device, where the channel indication information is used by the UE to determine the first downlink channel resource, and the frame listens to the first downlink channel.

歩骤 202、 UE根据接收到的信道指示信息，从网络侧设备分配给 UE的 Step 202: The UE allocates to the UE from the network side device according to the received channel indication information.

N个下行信道资源中，确定上述 N个下行信道的其中一个下行信道为第一下行信道，其中 N为大于等于 2的正整数，并侦听确定的第一下行信道； And determining, by the N downlink channel resources, one of the downlink channels of the N downlink channels is a first downlink channel, where N is a positive integer greater than or equal to 2, and listening to the determined first downlink channel;

歩骤 203、或者，网络侧设备分配给 UE的 N个下行信道资源中包括默认下行信道资源，若 UE未接收到信道指示信息， UE侦听该默认下行信道资源。 Step 203: The N downlink channel resources allocated by the network side device to the UE include the default downlink channel resource. If the UE does not receive the channel indication information, the UE listens to the default downlink channel resource.

进一歩地，上述信道指示信息是网络侧设备通过物理层信令承载的；相应地，歩骤 201， UE接收网络侧设备发送的信道指示信息，包括： UE接收网络侧设备发送的承载信道指示信息的物理层信令； Further, the channel indication information is carried by the network side device by using the physical layer signaling. Correspondingly, the UE receives the channel indication information sent by the network side device, where the UE includes: receiving, by the UE, the bearer channel indication sent by the network side device.

The foregoing physical layer signaling may indicate the first downlink channel resource by using an index direct mapping manner, or an index accumulation manner, or time information sent by the physical layer signaling.

UE接收网络侧设备发送的第一信令； Receiving, by the UE, the first signaling sent by the network side device;

UE根据第一信令，确定网络侧设备为 UE分配的 N个下行信道资源。其中，默认下行信道资源为网络侧设备为 UE预定义的；或者，默认下行信道资源为 UE根据网络侧设备发送的第二信令确定的。 The UE determines, according to the first signaling, N downlink channel resources allocated by the network side device to the UE. The default downlink channel resource is predefined by the network side device for the UE; or, the default downlink channel resource is determined by the UE according to the second signaling sent by the network side device.

具体来说， UE被预先分配至少两个下行信道资源，该下行信道资源可以为 DPCCH或者 F-DPCH资源，其中同一网络侧设备下的不同 UE可共享下行信道资源，并在不同时隙侦听共享的下行信道资源。 UE在上行传输前，接收网络侧设备发送的信道指示信息，根据信道指示信息确定当前时隙可侦听的第一下行信道。或者优选地，该 UE被分配的至少两个下行信道资源，包括默认下行信道，在 UE未接收到信道指示信息时，直接侦听默认下行信道。 UE在确定当前时隙侦听的下行信道资源后，侦听该确定的下行信道，并据此调整上行 E-DCH的发送功率，以进行上行传输。 Specifically, the UE is pre-allocated with at least two downlink channel resources, and the downlink channel resource may be a DPCCH or an F-DPCH resource, where different UEs under the same network side device may share Line channel resources, and listen to shared downlink channel resources in different time slots. Before receiving the uplink transmission, the UE receives the channel indication information sent by the network side device, and determines, according to the channel indication information, the first downlink channel that the current time slot can listen to. Or preferably, the UE is allocated at least two downlink channel resources, including a default downlink channel, and directly listens to the default downlink channel when the UE does not receive the channel indication information. After determining the downlink channel resource that the current time slot is listening to, the UE listens to the determined downlink channel, and adjusts the transmit power of the uplink E-DCH according to the uplink transmission.

具体实现时， UE从接收的物理层信令中获取信道指示信息，该信道指示信息可以为第一下行信道对应的物理层信令标识， UE根据该物理层信令标识来确定第一下行信道，其中该物理层信令包括但不限于图 1所示实施例中所述的 Absolute Grant Scope, E-RGCH包括的比特信息、 E-HICH包括的比特信息， HS-SCCH order, HS-SCCH order发送的时间信息也即 HS-SCCH order发送帧的子帧号来确定第一下行信道，其实现方法与图 1所示实施例中的方法对应，详细描述可以参见图 1对应的实施例的相关内容，此处不再赘述。 In a specific implementation, the UE obtains the channel indication information from the received physical layer signaling, where the channel indication information may be a physical layer signaling identifier corresponding to the first downlink channel, and the UE determines the first downlink according to the physical layer signaling identifier. a channel, where the physical layer signaling includes, but is not limited to, the Absolute Grant Scope described in the embodiment shown in FIG. 1, the bit information included in the E-RGCH, the bit information included in the E-HICH, HS-SCCH order, HS- The time information sent by the SCCH order, that is, the subframe number of the HS-SCCH order transmission frame, determines the first downlink channel, and the implementation method thereof corresponds to the method in the embodiment shown in FIG. 1.
