为了满足日益增长的对高速分组数据接入服务的需求, 3GPP ( 3rd Generation Partnership Project,第三代移动通信标准化组织)引入了 HSDPA(高 速下行分组接入, High Speed Downlink Packages Access )技术, 下行数据通 过 HSDPA 技术中的 HS-PDSCH ( High Speed Physical Downlink Shared Channel, 高速下行物理共享信道)可获得较高的用户峰值速率和小区数据吞 吐率并减少数据传输时延。 In order to meet the growing demand for high-speed packet data access services, 3GPP (3rd Generation Partnership Project) introduced HSDPA (High Speed Downlink Packages Access) technology, downlink data. The HS-PDSCH (High Speed Physical Downlink Shared Channel) in HSDPA technology can achieve higher user peak rate and cell data throughput rate and reduce data transmission delay.
在 HSDPA技术中, HS-SCCH ( Shared Control Channel for HS-DSCH, HS-DSCH的共享控制信道)是 HSDPA技术的下行调度控制信道, 用于指示 用户终端具体哪些时隙上配置了 HS-PDSCH。 In the HSDPA technology, the HS-SCCH (Shared Control Channel for HS-DSCH) is a downlink scheduling control channel of the HSDPA technology, and is used to indicate which time slots of the user equipment are configured with the HS-PDSCH.
目前, 小区中的公共信道是配置在主载波的子帧中的 TS0时隙上, 并且 要求辅载波的子帧中的 TS0时隙不能配置 HS-PDSCH. Currently, the common channel in the cell is configured on the TS0 slot in the subframe of the primary carrier, and the TS0 slot in the subframe requiring the secondary carrier cannot be configured with the HS-PDSCH.
随着技术的发展, 为了让系统能够支持更高的传输速率, 从而增加了小 区中的栽波数量。 由于栽波数量的增加, 辅载波的数量逐渐增大, 而每个辅 载波的子帧中的 TS0时隙都是空闲的, 从而浪费了大量的资源。 As technology evolves, the number of carriers in the cell is increased in order to allow the system to support higher transmission rates. As the number of carriers increases, the number of secondary carriers increases gradually, and the TS0 slots in the subframes of each secondary carrier are idle, thus wasting a lot of resources.
比如 9个载波配置情况, 其中, 为了保证主载波公共信道的小区覆盖满 足要求, 假设主载波的公共信道占用 3个栽波的功率资源, 剩余 6个辅载波
的子帧中的 TSO时隙就等价于一个栽波的所有资源。 也就是说, 9个栽波配 置情况下, 至少会浪费掉一个栽波的资源. For example, in the case of 9 carrier configurations, in order to ensure that the cell coverage of the common channel of the primary carrier satisfies the requirements, it is assumed that the common channel of the primary carrier occupies three power resources of the carrier, and the remaining six secondary carriers The TSO slot in the subframe is equivalent to all resources of a carrier. In other words, in the case of 9 carrier configurations, at least one resource will be wasted.
为了充分利用载波的资源, 可以在辅载波的子帧中的 TS0 时隙上配置 HS-PDSCH. In order to make full use of the resources of the carrier, HS-PDSCH can be configured on the TS0 slot in the subframe of the secondary carrier.
但是目前的 HS-SCCH只能指示 HS-PDSCH配置在 TS2时隙 ~ TS6时隙 的情况。 对于 HS-PDSCH配置在子帧中的 TS0时隙的情况, HS-SCCH没有 多余的比特进行指示, 所以现在还很难将 HS-PDSCH配置在子帧中的 TS0时 隙上。 However, the current HS-SCCH can only indicate that the HS-PDSCH is configured in the TS2 time slot to the TS6 time slot. In the case where the HS-PDSCH is configured in the TS0 slot in the subframe, the HS-SCCH has no redundant bits for indication, so it is now difficult to configure the HS-PDSCH on the TS0 slot in the subframe.
综上所述, 由于 HS-SCCH中没有多余的比特指示 HS-PDSCH配置在子 帧中的 TS0时隙的情况,所以目前很难将 HS-PDSCH配置到子帧中的 TS0时 隙上。 发明内容 In summary, since there are no redundant bits in the HS-SCCH indicating that the HS-PDSCH is configured in the TS0 slot in the subframe, it is currently difficult to configure the HS-PDSCH to the TS0 slot in the subframe.

本发明实施例 4艮据预先设定的时隙标识和时隙的对应关系, 确定没有配 置 HS-PDSCH的时隙对应的时隙标识, 并将确定的时隙标识向基站和用户终 端发送, 利用没有配置 HS-PDSCH的时隙对应的 HS-SCCH承栽的指示信息,
作为子帧中第一个时隙的指示信息.由于能够根据 HS-SCCH指示 HS-PDSCH 配置到子帧中的 TS0时隙的情况, 使得 HS-PDSCH可以配置到子帧中的 TS0 时隙上, 从而节省了载波的资源, 提高了资源利用率。 In the fourth embodiment of the present invention, the time slot identifier corresponding to the time slot in which the HS-PDSCH is not configured is determined according to the preset relationship between the time slot identifier and the time slot, and the determined time slot identifier is sent to the base station and the user terminal. Using the indication information of the HS-SCCH bearer corresponding to the time slot in which the HS-PDSCH is not configured, As the indication information of the first slot in the subframe. The HS-PDSCH can be configured to the TS0 slot in the subframe because the HS-PDCH can be configured to indicate the case of the TS0 slot in the subframe according to the HS-SCCH. , thereby saving carrier resources and improving resource utilization.
如图 1所示, 本发明实施例资源指示的系统包括: 高层设备 10、 基站 20 和用户终端 30。 As shown in FIG. 1, the system for resource indication in the embodiment of the present invention includes: a high-level device 10, a base station 20, and a user terminal 30.
高层设备 10, 用于从子帧中的第一个上行时隙之后的时隙中, 确定没有 配置 HS-PDSCH的时隙, 才艮据预先设定的时隙标识和时隙的对应关系, 确定 没有配置 HS-PDSCH的时隙对应的时隙标识, 发送确定的时隙标识。 The high-level device 10 is configured to determine, from the time slot after the first uplink time slot in the subframe, the time slot in which the HS-PDSCH is not configured, according to the preset relationship between the time slot identifier and the time slot. The time slot identifier corresponding to the time slot in which the HS-PDSCH is not configured is determined, and the determined time slot identifier is sent.
基站 20, 用于在收到来自高层设备 10的时隙标识后, 将 HS-SCCH承载 的该时隙标识对应的时隙的指示信息, 作为子帧中第一个时隙的指示信息。 The base station 20 is configured to: after receiving the time slot identifier from the upper layer device 10, the indication information of the time slot corresponding to the time slot identifier carried by the HS-SCCH as the indication information of the first time slot in the subframe.
用户终端 30,用于在收到来自高层设备 10的时隙标识后,根据 HS-SCCH 承栽的该时隙标识对应的时隙的指示信息, 确定子帧中第一个时隙是否配置 HS-PDSCH。 The user terminal 30 is configured to determine, according to the indication information of the time slot corresponding to the time slot identifier carried by the HS-SCCH, after receiving the time slot identifier from the high-layer device 10, whether the HS is configured in the first time slot in the subframe. -PDSCH.
其中, 子帧中的第一个上行时隙是子帧中的 TS1 时隙, 之后的时隙是子 帧中的 TS2时隙 ~ TS6时隙, 子帧中的第一个时咪是子帧中的 TS0时隙。 The first uplink time slot in the subframe is the TS1 time slot in the subframe, and the subsequent time slot is the TS2 time slot to the TS6 time slot in the subframe, and the first time slot in the subframe is a subframe. The TS0 slot in the middle.
如图 2所示, 本发明实施例高层设备的结构示意图: 时隙确定模块 100、 As shown in FIG. 2, a schematic structural diagram of a high-level device according to an embodiment of the present invention: a time slot determining module 100,
J J
标识确定模块 110和标识发送模块 120。 3 时隙确定模块 100, 用于从子帧中的第一个上行时隙之后的时隙中,确定 没有配置 HS-PDSCH的时隙。 The identification determining module 110 and the identification transmitting module 120. The three- slot determining module 100 is configured to determine, from the time slot after the first uplink time slot in the subframe, a time slot in which the HS-PDSCH is not configured.
在具体进行时隙配置时,需要在子帧中的第一个上行时隙之后的时隙(即 TS2时隙 ~ TS6时隙) 中, 为 HS-SCCH分配一个下行时隙, 这样就至少有一 个时隙是不会配置 HS-PDSCH的, 本实施例可以用这个时隙的指示信息来指 示子帧中的第一个时隙。 In the specific time slot configuration, it is necessary to allocate a downlink time slot for the HS-SCCH in the time slot after the first uplink time slot in the subframe (ie, TS2 time slot to TS6 time slot), so that at least A time slot is not configured with the HS-PDSCH. In this embodiment, the indication information of the time slot can be used to indicate the first time slot in the subframe.
当然, 在具体实施过程中, 还有可能出现 TS2时隙 ~ TS6时隙中, 有多 个时隙都没有配置 HS-PDSCH, 比如在 TS2时隙 ~ TS6时隙中配置了多个上 行时隙, 则上行时隙中是不能配置 HS-PDSCH的, 这时可以确定所有没有配 置的 HS-PDSCH 的时隙, 也可以只选择其中一部分或一个没有配置的
HS-PDSCH的时隙。 Of course, in the specific implementation process, there may be a TS2-slot to a TS6 time slot, and no HS-PDSCH is configured in multiple time slots, for example, multiple uplink time slots are configured in the TS2 time slot to the TS6 time slot. The HS-PDSCH cannot be configured in the uplink time slot. In this case, all the time slots of the HS-PDSCH that are not configured can be determined, or only some of them or one of the unconfigured ones can be selected. The time slot of the HS-PDSCH.
如果只是选择其中的一部分或一个时隙, 则选择的方式包括但不限于下 列方式中的一种: If only a part of it or a time slot is selected, the manner of selection includes but is not limited to one of the following modes:
随机选择、 按照时隙的顺序轮流选择、 按照时隙的顺序从前到后选择或 从后到前选择等。 Randomly selected, rotated in the order of time slots, selected from front to back in the order of time slots, or selected from back to front.
标识确定模块 110, 用于根据预先设定的时隙标识和时隙的对应关系, 确 定时隙确定模块 100确定的时隙对应的时咪标识。 The identifier determining module 110 is configured to determine a time-of-middle identifier corresponding to the time slot determined by the time slot determining module 100 according to a preset relationship between the time slot identifier and the time slot.
其中, 时咪标识和时隙的对应关系可以根据需要进行设定, 时隙标识可 以是数字, 字母或其他能够区分的信息。 The correspondence between the time meter identifier and the time slot may be set according to requirements, and the time slot identifier may be a number, a letter or other distinguishable information.
比如, 时隙标识和时隙的对应关系可以参见表 1 : For example, the correspondence between time slot identifiers and time slots can be seen in Table 1:
较佳的方式是在表 1中在设置一个特殊标识, 标识 TS0不可用, 这样在 子帧中的第一个时隙 (即 TS0 )不能使用或者 TS2时隙 ~ TS6时隙中都配置 了 HS-PDSCH, 时隙确定模块 100就不会确定对应的时隙, 而标识确定模块 110 就可以确定特殊标识, 相应的基站和用户终端收到特殊标识后, 就知道 TS0上不会配置 HS-PDSCH, 具体可以参见表 2: The preferred way is to set a special identifier in Table 1, and identify that TS0 is not available, so that the first time slot (ie, TS0) in the subframe cannot be used or the HS2 time slot ~ TS6 time slot are configured with HS. - The PDSCH, the time slot determining module 100 does not determine the corresponding time slot, and the identity determining module 110 can determine the special identifier. After receiving the special identifier, the corresponding base station and the user terminal know that the HS-PDSCH is not configured on the TS0. For details, see Table 2:
表 2 Table 2
在具体实施过程中, 时隙标识和时隙的对应关系可以存储到本实施例的 高层设备中; 也可以存储到其他设备中, 供高层设^吏用。 In a specific implementation process, the corresponding relationship between the time slot identifier and the time slot may be stored in the high-level device of the embodiment; or may be stored in other devices for high-level configuration.
需要说明的是, 在实施过程中, 需要保证高层设备使用的时隙标识和时 隙的对应关系, 与用户终端和基站使用的时隙标识和时隙的对应关系相同。
标识发送模块 120,用于将标识确定模块 110确定的时隙标识发送给基站 和用户终端, 指示基站将 HS-SCCH承栽的该时隙标识对应的时隙的指示信 息,作为子帧中第一个时隙的指示信息, 以及指示用户终端根据 HS-SCCH承 载的该时隙标识对应的时隙的指示信息, 确定子帧中第一个时隙是否配置 HS-PDSCH。 It should be noted that, in the implementation process, the correspondence between the slot identifier and the slot used by the high-level device needs to be ensured, and the correspondence between the slot identifier and the slot used by the user terminal and the base station is the same. The identifier sending module 120 is configured to send the slot identifier determined by the identifier determining module 110 to the base station and the user terminal, and instruct the base station to use the indication information of the time slot corresponding to the slot identifier carried by the HS-SCCH as the subframe. The indication information of one time slot, and the indication information indicating that the user terminal according to the time slot corresponding to the time slot identifier carried by the HS-SCCH determines whether the first time slot in the subframe is configured with the HS-PDSCH.
其中, 标识发送模块 120可以先将时隙标识发送给用户终端, 也可以先 将时隙标识发送给基站, 还可以将时隙标识同时发给基站和用户终端。 The identifier sending module 120 may first send the slot identifier to the user terminal, or may first send the slot identifier to the base station, and may also send the slot identifier to the base station and the user terminal simultaneously.
在具体实施过程中, 标识发送模块 120可以通过高层信令向基站和用户 终端发送标识确定模块 110确定的时隙标识。 In a specific implementation process, the identifier sending module 120 may send the slot identifier determined by the identifier determining module 110 to the base station and the user terminal by using the high layer signaling.
发送给基站的时隙标识可以通过小区级配置或用户级配置实现。 具体的, 小区级配置是在物理共享信道的有关消息中携带时隙标识发送, 比如物 理共享信道重配置资源。 The slot identifier sent to the base station can be implemented by cell level configuration or user level configuration. Specifically, the cell-level configuration carries a slot identifier transmission, such as a physical shared channel reconfiguration resource, in a related message of the physical shared channel.
用户级配置是在高层设备配置物理共享信道资源之后, 在每个用户终端 的有关配置消息中携带时隙标识来通知基站, 比如无线链路建立的相关信息、 无线链路重配准备的相关信息、 无线链路重配的相关信息、 无线链路添加的 相关信息等。 The user-level configuration is to notify the base station, for example, the information about the establishment of the radio link and the information about the reconfiguration of the radio link, in the configuration message of each user terminal, after the physical device shares the physical shared channel resource. Information related to radio link reconfiguration, information about radio link addition, etc.
发送给用户终端的时隙标识同样有两种方式。 具体的, There are also two ways to send the time slot identifier to the user terminal. specific,
第一种: 在用户终端的有关配置消息中携带时隙标识, 比如 RB ( Radio Bearer, 无线承载)建立、 RB重配、 物理信道重配、 传输信道重配等; The first type: carries the time slot identifier in the configuration message of the user terminal, such as RB (Radio Bearer) establishment, RB reconfiguration, physical channel reconfiguration, and transmission channel reconfiguration.
第二种: 可以在广播消息中携带时咪标识, 比如在增强业务中通过广播 消息携带时隙标识。 The second type: The time code identifier can be carried in the broadcast message, for example, the time slot identifier is carried by the broadcast message in the enhanced service.
具体采用什么消息携带时隙标识可以根据需要进行设定, 然后通过协议 配置到高层设备、 基站和用户终端, 或者由高层设备告知基站和用户终端, 这样基站和用户终端就知道具体什么消息携带时隙标识了。 What kind of message carrying time slot identifier can be set as needed, and then configured to the high-level device, the base station, and the user terminal through a protocol, or the high-level device informs the base station and the user terminal, so that the base station and the user terminal know what specific message is carried. The gap is identified.
本实施例中的高层设备可以是 RNC ( Radio Network Controller,无线网络 控制器) 。 The high-level device in this embodiment may be an RNC (Radio Network Controller).
如图 3所示, 本发明实施例的基站包括: 第一标识接收模块 200和第一

其中, 第一处理模块 210根据预先设定的时咪标识和时隙的对应关系, 确定第一标识接收模块 200收到的时隙标识对应的时隙,将 HS-SCCH承载的 该时隙标识对应的时隙的指示信息, 作为子帧中第一个时隙的指示信息。 The first processing module 210 determines, according to the preset correspondence between the time-of-time identifier and the time slot, the time slot corresponding to the time slot identifier received by the first identity receiving module 200, and the time slot identifier carried by the HS-SCCH. The indication information of the corresponding time slot is used as the indication information of the first time slot in the subframe.
其中, 第一个时隙的指示信息是根据第一个时隙是否配置 HS-PDSCH确 定的。 The indication information of the first time slot is determined according to whether the first time slot is configured with the HS-PDSCH.
比如时隙标识对应的时隙是 TS2 时隙, 则如果第一个时隙配置 HS-PDSCH, 将 HS-SCCH承载的 TS2时隙对应的指示信息设置为 1; 如果第 一个时隙没有配置 HS-PDSCH, 将 HS-SCCH承栽的 TS2时隙对应的指示信 息设置为 0。 For example, if the time slot corresponding to the time slot identifier is a TS2 time slot, if the first time slot is configured with the HS-PDSCH, the indication information corresponding to the TS2 time slot carried by the HS-SCCH is set to 1; if the first time slot is not configured HS-PDSCH sets the indication information corresponding to the TS2 slot of the HS-SCCH to 0.
1和 0也可以由其他信息替代,但是需要事先让用户终端知道每个信息分 别代表什么含义。 1 and 0 can also be replaced by other information, but it is necessary to let the user terminal know in advance what each message represents.
在具体实施过程中, 时隙标识和时隙的对应关系可以存储到本实施例的 基站中; 也可以存储到其他设备中, 供基站使用。 In a specific implementation process, the correspondence between the time slot identifier and the time slot may be stored in the base station in this embodiment; or may be stored in other devices for use by the base station.
如图 4所示, 本发明实施例的用户终端包括: 第二标识接收模块 300和 第二处理模块 310。 As shown in FIG. 4, the user terminal of the embodiment of the present invention includes: a second identifier receiving module 300 and a second processing module 310.
第二标识接收模块 300, 用于接收来自高层设备的时隙标识。 The second identifier receiving module 300 is configured to receive a slot identifier from a high-level device.

其中, 第二处理模块 310根据预先设定的时隙标识和时隙的对应关系, 确定笫二标识接收模块 300收到的时隙标识对应的时隙,根据 HS-SCCH承载 的该时隙标识对应的时隙的指示信息, 确定子帧中第一个时隙是否配置 HS-PDSCH. The second processing module 310 determines, according to the preset relationship between the time slot identifier and the time slot, the time slot corresponding to the time slot identifier received by the second identifier receiving module 300, according to the time slot identifier carried by the HS-SCCH. The indication information of the corresponding time slot determines whether the first time slot in the subframe is configured with HS-PDSCH.
比如: 时隙标识对应的时隙是 TS2时隙, 如果 HS-SCCH承载的 TS2时
隙对应的指示信息为 1, 则确定子帧中第一个时隙配置 HS-PDSCH; 如果 HS-SCCH承载的 TS2时隙对应的指示信息为 0, 则确定子帧中第一个时隙没 有配置 HS-PDSCH。 For example, the time slot corresponding to the time slot identifier is the TS2 time slot, if the TS-SCCH carries the TS2 time. If the indication information corresponding to the slot is 1, the first time slot in the subframe is configured to configure the HS-PDSCH; if the indication information corresponding to the TS2 time slot carried by the HS-SCCH is 0, it is determined that the first time slot in the subframe does not exist. Configure HS-PDSCH.
在具体实施过程中, 时咪标识和时隙的对应关系可以存储到本实施例的 用户终端中; 也可以存储到其他设备中, 供用户终端使用。 In a specific implementation process, the correspondence between the time zone identifier and the time slot may be stored in the user terminal in this embodiment; or may be stored in other devices for use by the user terminal.
如图 5所示, 本发明实施例资源指示的方法包括下列步骤: As shown in FIG. 5, the method for resource indication in the embodiment of the present invention includes the following steps:
其中, 子帧中的第一个上行时隙是子帧中的 TS1 时隙, 之后的时隙是子 帧中的 TS2时隙 ~ TS6时隙, 子帧中的第一个时咪是子帧中的 TS0时隙。 The first uplink time slot in the subframe is the TS1 time slot in the subframe, and the subsequent time slot is the TS2 time slot to the TS6 time slot in the subframe, and the first time slot in the subframe is a subframe. The TS0 slot in the middle.
步骤 500、 高层设备从子帧中的第一个上行时隙之后的时隙中,确定没有 配置 HS-PDSCH的时隙。 Step 500: The high-level device determines, from the time slot after the first uplink time slot in the subframe, the time slot in which the HS-PDSCH is not configured.
在具体进行时隙配置时,需要在子帧中的第一个上行时咪之后的时隙(即 TS2时隙 ~ TS6时隙) 中, 为 HS-SCCH分配一个下行时隙, 这样就至少有一 个时隙是不会配置 HS-PDSCH, 本实施例可以用这个时隙的指示信息来指示 子帧中的第一个时隙。 In the specific time slot configuration, it is necessary to allocate a downlink time slot for the HS-SCCH in the time slot after the first uplink time in the subframe (ie, TS2 time slot to TS6 time slot), so that at least One slot is not configured with the HS-PDSCH. In this embodiment, the indication information of this slot can be used to indicate the first slot in the subframe.
当然, 在具体实施过程中, 还有可能出现 TS2时隙 ~ TS6时隙中, 有多 个时隙都没有配置 HS-PDSCH, 比如在 TS2时隙 ~ TS6时咪中配置了多个上 行时隙, 则上行时隙中是不能配置 HS-PDSCH的, 这时可以确定所有没有配 置的 HS-PDSCH 的时隙, 也可以只选择其中一部分或一个没有配置的 HS-PDSCH的时隙。 Of course, in the specific implementation process, there may be a TS2-slot to a TS6 time slot, and no HS-PDSCH is configured in multiple time slots. For example, multiple uplink time slots are configured in the TS2 time slot to the TS6 time slot. If the HS-PDSCH is not configured in the uplink time slot, all the time slots of the HS-PDSCH that are not configured may be determined, or only one of the slots of the HS-PDSCH that is not configured may be selected.
如果只是选择其中的一部分或一个时咪, 则选择的方式包括但不限于下 列方式中的一种: If you just select a part or a time, then the choices include but are not limited to one of the following:
随机选择、 按照时隙的顺序轮流选择、 按照时隙的顺序从前到后选择或 从后到前选择等。 Randomly selected, rotated in the order of time slots, selected from front to back in the order of time slots, or selected from back to front.
步骤 501、 高层设备才 据预先设定的时隙标识和时隙的对应关系,确定没 有配置 HS-PDSCH的时隙对应的时隙标识。 Step 501: The high-level device determines the slot identifier corresponding to the time slot in which the HS-PDSCH is not configured according to the preset relationship between the slot identifier and the slot.
其中, 时隙标识和时隙的对应关系可以根据需要进行设定, 时隙标识可 以是数字, 字母或其他能够区分的信息。
时隙标识和时隙的对应关系可以参见表 1。 The correspondence between the time slot identifier and the time slot may be set according to requirements, and the time slot identifier may be a number, a letter or other distinguishable information. For the correspondence between the slot identifier and the slot, refer to Table 1.
较佳的方式是在表 1 中在设置一个特殊标识, 标识 TS0不可用, 这样在 子帧中的第一个时隙 (即 TS0 )不能使用或者 TS2时隙 ~ TS6时隙中都配置 了 HS-PDSCH, 则步骤 500中就不会确定对应的时隙, 而步骤 501中就可以 确定特殊标识, 相应的基站和用户终端收到特殊标识后, 就知道 TS0上不会 配置 HS-PDSCH, 具体可以参见表 2„ The preferred way is to set a special identifier in Table 1, and identify that TS0 is not available, so that the first time slot (ie, TS0) in the subframe cannot be used or the HS2 time slot ~ TS6 time slot are configured with HS. -PDSCH, the corresponding time slot will not be determined in step 500, and the special identifier can be determined in step 501. After receiving the special identifier, the corresponding base station and user terminal know that HS-PDSCH is not configured on TS0. See Table 2
在具体实施过程中, 时咪标识和时咪的对应关系可以存储到本实施例的 高层设备中; 也可以存储到其他设备中, 供高层设^吏用。 In a specific implementation process, the correspondence between the time meter identifier and the time microphone can be stored in the high-level device of the embodiment; or can be stored in other devices for high-level configuration.
需要说明的是, 在实施过程中, 需要保证高层设备使用的时隙标识和时 隙的对应关系, 与用户终端和基站使用的时隙标识和时隙的对应关系相同。 It should be noted that, in the implementation process, the correspondence between the time slot identifier and the time slot used by the high-level device needs to be ensured, which is the same as the corresponding relationship between the time slot identifier and the time slot used by the user terminal and the base station.
步骤 502、 高层设备将确定的时隙标识发送给基站和用户终端, 指示基站 将 HS-SCCH承载的该时隙标识对应的时隙的指示信息,作为子帧中第一个时 隙的指示信息,以及指示用户终端根据 HS-SCCH承载的该时隙标识对应的时 隙的指示信息, 确定子帧中第一个时隙是否配置 HS-PDSCH。 Step 502: The high-level device sends the determined time slot identifier to the base station and the user terminal, and indicates that the base station uses the indication information of the time slot corresponding to the time slot identifier carried by the HS-SCCH as the indication information of the first time slot in the subframe. And indicating that the user equipment determines, according to the indication information of the time slot corresponding to the time slot identifier carried by the HS-SCCH, whether the first time slot in the subframe is configured with the HS-PDSCH.
其中, 高层设备可以先将时隙标识发送给用户终端, 也可以先将时隙标 识发送给基站, 还可以将时隙标识同时发给基站和用户终端。 The high-level device may first send the time slot identifier to the user terminal, or may first send the time slot identifier to the base station, and may also send the time slot identifier to the base station and the user terminal.
在具体实施过程中, 高层设备可以通过高层信令向基站和用户终端发送 确定的时隙标识。 In a specific implementation process, the high-level device may send the determined time slot identifier to the base station and the user terminal through high-level signaling.
发送给基站的时隙标识可以通过小区级配置或用户级配置实现。 具体的, 小区级配置是在物理共享信道的有关消息中携带时隙标识发送, 比如物 理共享信道重配置; The slot identifier sent to the base station can be implemented by cell level configuration or user level configuration. Specifically, the cell-level configuration carries a slot identifier transmission in a related message of the physical shared channel, for example, physical shared channel reconfiguration;
用户级配置是在高层设备配置物理共享信道资源之后, 在每个用户终端 的有关配置消息中携带时咪标识来通知基站, 比如无线链路建立的相关信息、 无线链路重配准备的相关信息、 无线链路重配的相关信息、 无线链路添加的 相关信息等。 The user-level configuration is to notify the base station, such as the information about the establishment of the wireless link and the information about the reconfiguration of the wireless link, in the configuration message of each user terminal after the physical device shares the physical shared channel resource. Information related to radio link reconfiguration, information about radio link addition, etc.
发送给用户终端的时隙标识同样有两种方式, 具体的, There are also two ways to send the time slot identifier to the user terminal. Specifically,
第一种: 在用户终端的有关配置消息中携带时咪标识, 比如 RB 建立、
RB重配、 物理信道重配、 传输信道重配等; The first type: carries the time identifier in the configuration message of the user terminal, such as RB establishment, RB reconfiguration, physical channel reconfiguration, transmission channel reconfiguration, etc.;
第二种: 可以在广播消息中携带时咪标识, 比如在增强业务中通过广播 消息携带时隙标识。 The second type: The time code identifier can be carried in the broadcast message, for example, the time slot identifier is carried by the broadcast message in the enhanced service.
具体采用什么消息携带时隙标识可以根据需要进行设定, 然后通过协议 配置到高层设备、 基站和用户终端, 或者由高层设备告知基站和用户终端, 这样基站和用户终端就知道具体什么消息携带时隙标识了。 What kind of message carrying time slot identifier can be set as needed, and then configured to the high-level device, the base station, and the user terminal through a protocol, or the high-level device informs the base station and the user terminal, so that the base station and the user terminal know what specific message is carried. The gap is identified.
本实施例中的高层设备可以是 R C. The high-level device in this embodiment may be R C.
其中, 步骤 502之后还可以进一步包括: The step 502 may further include:
步骤 503、基站 据时隙标识和时隙的对应关系,确定收到的来自高层设 备的时隙标识对应的时咪,将 HS-SCCH承栽的该时隙标识对应的时隙的指示 信息, 作为子帧中第一个时隙的指示信息。 Step 503: The base station determines, according to the correspondence between the time slot identifier and the time slot, the received time slot corresponding to the time slot identifier of the received high-level device, and the indication information of the time slot corresponding to the time slot identifier of the HS-SCCH. As indication information of the first time slot in the subframe.
其中, 第一个时隙的指示信息是根据第一个时隙是否配置 HS-PDSCH确 定的。 The indication information of the first time slot is determined according to whether the first time slot is configured with the HS-PDSCH.
比如时隙标识对应的时隙是 TS2 时隙, 则如果第一个时隙配置 HS-PDSCH, 将 HS-SCCH承载的 TS2时咪对应的指示信息设置为 1; 如果第 一个时隙没有配置 HS-PDSCH, 将 HS-SCCH承栽的 TS2时隙对应的指示信 息设置为 0。 For example, if the time slot corresponding to the time slot identifier is a TS2 time slot, if the first time slot is configured with the HS-PDSCH, the indication information corresponding to the TS2 time of the HS-SCCH is set to 1; if the first time slot is not configured HS-PDSCH sets the indication information corresponding to the TS2 slot of the HS-SCCH to 0.
1和 0也可以由其他信息替代,但是需要事先让用户终端知道每个信息分 别代表什么含义。 1 and 0 can also be replaced by other information, but it is necessary to let the user terminal know in advance what each message represents.
在具体实施过程中, 时隙标识和时 Rji的对应关系可以存储到本实施例的 基站中; 也可以存储到其他设备中, 供基站使用。 In a specific implementation process, the correspondence between the time slot identifier and the time Rji may be stored in the base station in this embodiment; or may be stored in other devices for use by the base station.
步骤 504、用户终端才艮据时隙标识和时隙的对应关系,确定收到的来自高 层设备的时隙标识对应的时隙,根据 HS-SCCH承载的该时隙标识对应的时隙 的指示信息, 确定子帧中第一个时隙是否配置 HS-PDSCH。 Step 504: The user terminal determines, according to the correspondence between the time slot identifier and the time slot, the received time slot corresponding to the time slot identifier of the high-layer device, according to the indication of the time slot corresponding to the time slot identifier carried by the HS-SCCH. Information, determine whether the first time slot in the subframe is configured with HS-PDSCH.
比如: 时隙标识对应的时隙是 TS2时隙, 如果 HS-SCCH承栽的 TS2时 隙对应的指示信息为 1 , 则确定子帧中第一个时隙配置 HS-PDSCH; 如果 HS-SCCH承载的 TS2时隙对应的指示信息为 0, 则确定子帧中第一个时隙没
有配置 HS-PDSCH, For example, if the time slot corresponding to the time slot identifier is a TS2 time slot, if the indication information corresponding to the TS2 time slot of the HS-SCCH is 1, the first time slot in the subframe is determined to be configured with the HS-PDSCH; if the HS-SCCH If the indication information corresponding to the bearer TS2 slot is 0, it is determined that the first slot in the subframe is not Have configured HS-PDSCH,
在具体实施过程中, 时隙标识和时隙的对应关系可以存储到本实施例的 用户终端中; 也可以存储到其他设备中, 供用户终端使用。 In a specific implementation process, the correspondence between the time slot identifier and the time slot may be stored in the user terminal in this embodiment; or may be stored in other devices for use by the user terminal.
需要说明的是, 步骤 503和步骤 504之间没有先后顺序, 具体取决于用 户终端和基站收到的时隙标识的时间。 如果用户终端先收到时隙标识, 则先 执行步骤 504; 如果基站先收到时隙标识, 则先执行步骤 503; 如果基站和用 户终端同时收到时隙标识, 则同时执行步骤 503和步骤 504. It should be noted that there is no sequence between step 503 and step 504, depending on the time slot identifiers received by the user terminal and the base station. If the user terminal first receives the time slot identifier, step 504 is performed first; if the base station receives the time slot identifier first, step 503 is performed first; if the base station and the user terminal receive the time slot identifier at the same time, step 503 and steps are simultaneously performed. 504.
