Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for sending uplink data, a user equipment, and a base station.
Background
Semi-Persistent Scheduling (SPS) and dynamic Scheduling are two of the most mature uplink data access methods in the prior art.
SPS allows semi-static configuration of radio resources and periodic allocation of the resources to a particular user equipment. As shown in fig. 1, in brief, a Physical Downlink Control Channel (PDCCH) scrambled by a base station using an SPS cell radio network temporary identity (C-RNTI) in a certain subframe specifies a radio resource (referred to as SPS resource herein) used by a user equipment, and the SPS resource is used by the user equipment to transmit or receive data every one period. The SPS has the characteristics of one-time distribution and multiple use, and digital copyright unique identifiers (DCI) including uplink or downlink DCI do not need to be issued for the user equipment in each subframe, so that the corresponding PDCCH overhead is reduced.
Unlike SPS, dynamic scheduling only occurs when the user equipment has uplink data to transmit. As shown in fig. 2, the ue tells the base station whether uplink resources are needed for uplink data transmission through a Scheduling Request (SR), but does not tell the base station how much uplink data needs to be sent. After receiving the SR, the base station allocates how many uplink resources to the user equipment depends on the implementation of the base station, and a common practice is to allocate at least enough resources for the user equipment to send a Buffer Status Report (BSR). If the user equipment does not have uplink data to transmit, the base station does not allocate uplink resources for the user equipment, thereby avoiding the waste of resources.
In order to reduce the access delay, a method of reducing an SPS period, an SR period, or allocating a UL Grant (PDCCH) to the user equipment when the user equipment has no uplink resource request may be employed. However, shortening the SR period can only reduce a small part of uplink scheduling delay in most cases, and the method of allocating UL Grant (PDCCH) to the user equipment when the user equipment has no uplink resource request not only causes uplink resource waste, but also causes PDCCH overhead to be increased seriously. Although the uplink access delay can be significantly reduced by reducing the SPS period without a serious PDCCH overhead problem, the allocated resources cannot be used by other user equipments, and thus uplink resources are seriously wasted.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First embodiment
According to an aspect of the embodiments of the present invention, there is provided a method for transmitting uplink data, which is applied to a first user equipment, as shown in fig. 3, the method includes:
step S31, sending a first indication for indicating that the first user equipment uses the shared resource to at least one second user equipment through the first dedicated resource configured by the base station.
The first user equipment and at least one second user equipment belong to the same user equipment group, and the shared resource is the shared resource of the user equipment group. The first dedicated resource is configured by the base station for the first user equipment, and the first dedicated resource is used for the first user equipment to send the willingness to use the shared resource, that is, when the first user equipment needs to send uplink data, a first indication for indicating that the first user equipment uses the shared resource may be sent on the first dedicated resource. Of course, it can be understood that, when the first user equipment does not need to transmit uplink data, an indication indicating that the first user equipment does not need to use the shared resource may be transmitted on the first dedicated resource, so that other user equipments in the same user equipment group as the first user equipment may know the usage requirement of the first user equipment for the shared resource.
When the first user equipment needs to send uplink data, all 1-bit of 1 byte can be sent on the first dedicated resource, and when the first user equipment does not need to send uplink data, all 0-bit can be sent on the first dedicated resource, and the sent data can be scrambled by the Group RNTI. Of course, it is understood that the specific transmission form of the indication indicating whether the first user equipment needs to use the shared resource is not limited thereto.
Step S33, determining, according to the first indication, a first shared resource block that can be used by the first user equipment in the shared resource.
Because the first dedicated resource has a frequency band position where the first dedicated resource is located, and the frequency band positions where the dedicated resources of different user equipment are located are different, the specific position of the shared resource used by each user equipment for sending uplink data can be conveniently determined according to the frequency band position where the respective dedicated resource is located. For example, if the dedicated resource of a certain ue is in the low frequency band, the ue may use the low frequency part of the shared resource to transmit uplink data.
Step S37, sending uplink data of the first user equipment to the base station through the first shared resource block according to the priority order of the shared resources used by the first user equipment and the at least one second user equipment.
Before the user equipment sends uplink data, the base station configures shared resources for the scheduled user equipment and configures corresponding priority. In the uplink data transmission method according to the embodiment of the present invention, the base station may further configure, for the ue, a dedicated resource for transmitting a usage requirement of the ue for the shared resource. Wherein, the priority of the user equipment configured with the proprietary resource is higher than that of the user equipment not configured with the proprietary resource, because the user equipment configured with the proprietary resource has the highest usage right of the shared resource.
Since the first user equipment is configured with the first dedicated resource, when the first user equipment sends the first indication for indicating that the first user equipment uses the shared resource on the first dedicated resource, the first user equipment sends uplink data by using the shared resource in preference to the user equipment which is not configured with the dedicated resource.
In this embodiment, when the second user equipment does not configure the dedicated resource, the priority of the first user equipment is higher than that of the second user equipment, and as long as the first user equipment needs to send uplink data, the first user equipment may preempt the shared resource to send the uplink data in preference to the second user equipment.
If the first user equipment is the only user equipment configured with the exclusive resource in the user equipment group where the first user equipment is located, the priority of the first user equipment is the highest, and the first user equipment may not have the willingness to monitor the shared resources of other user equipment. However, if the first ue is not the only ue configured with the dedicated resource in the ue group where the first ue is located, the first ue must monitor the willingness of the other ues to use the shared resource, that is, must receive an indication whether the other ues configured with the dedicated resource use the shared resource or not.
Of course, for a ue group, which ues need to configure the dedicated resource and which ues do not need to configure the dedicated resource may be determined according to the latency requirement of the ues. For example, a UE group includes a UE with low latency requirements and one or more UEs with no latency sensitivity, the UE with low latency requirements is configured with dedicated resources, and the UE with no latency sensitivity is not configured with dedicated resources. Then, the UE with low latency need only indicate its own requirement for shared resources on the dedicated resources, and does not need to monitor the requirement information of other UEs; the UE insensitive to time delay only needs to monitor the requirement information received on the special resource and does not need to send the requirement information of the UE. As shown in fig. 4, when the UE with low latency requirement indicates on the dedicated resource that it needs to use the shared resource, the shared resource is its own share; when the UE with low latency requirements indicates on the dedicated resources that it does not need to use the shared resource, the shared resource is used by the (or one) latency insensitive UEs. Wherein, as shown in fig. 5, when a plurality of delay insensitive UEs exist, the UEs use the shared resources according to the priority order configured by the base station, for example, in a polling manner.
Therefore, the method for sending uplink data according to the embodiment of the present invention enables the ue with the highest usage right of the shared resource to send the usage requirement of the shared resource on the dedicated resource of the ue, and preferentially seizes the shared resource when the shared resource needs to be used, thereby meeting the requirement of the low-latency user, enabling the resource allocated by the base station to be used by other ues, and avoiding resource waste.
Second embodiment
According to another aspect of the embodiments of the present invention, there is provided a method for transmitting uplink data, which is applied to a first user equipment, as shown in fig. 6, the method includes:
step S31, sending a first indication for indicating that the first user equipment uses the shared resource to at least one second user equipment through the first dedicated resource configured by the base station.
The first user equipment and at least one second user equipment belong to the same user equipment group, and the shared resource is the shared resource of the user equipment group. The first dedicated resource is configured by the base station for the first user equipment, and the first dedicated resource is used for the first user equipment to send the willingness to use the shared resource, that is, when the first user equipment needs to send uplink data, a first indication for indicating that the first user equipment uses the shared resource may be sent on the first dedicated resource. Of course, it can be understood that, when the first user equipment does not need to transmit uplink data, an indication that the first user equipment does not need to use the shared resource may be transmitted on the first dedicated resource, so that other user equipments in the same user equipment group as the first user equipment may know the usage requirement of the first user equipment for the shared resource.
Step S33, determining, according to the first indication, a first shared resource block that can be used by the first user equipment in the shared resource.
Because the first dedicated resource has a frequency band position where the first dedicated resource is located, and the frequency band positions where the dedicated resources of different user equipment are located are different, the specific position of the shared resource used by each user equipment for sending uplink data can be conveniently determined according to the frequency band position where the respective dedicated resource is located. For example, if the dedicated resource of a certain ue is in the low frequency band, the ue may use the low frequency part of the shared resource to transmit uplink data.
Step S35, the first ue receives a second indication, sent by at least one second ue through a second dedicated resource configured by the base station, for indicating that the second ue uses the shared resource.
In the uplink data transmission method according to the embodiment of the present invention, the second user equipment is configured with the second dedicated resource. Therefore, when the second user equipment needs to transmit uplink data, the second user equipment may also transmit a second indication on the second dedicated resource, the second indication indicating that the second user equipment uses the shared resource. Since the first user equipment and the second user equipment are in the same user equipment group, the first user equipment needs to monitor the use requirement of the other user equipment configured with the dedicated resource in the same group for the dedicated resource.
Therefore, the second indication sent by the second user equipment on the second dedicated resource will be received by the first user equipment. Of course, the first indication sent by the first user equipment on the first dedicated resource will also be received by the second user equipment.
In this case, the first user equipment and the second user equipment each send their own usage requirements for the shared resource via the corresponding dedicated resource. However, how to transmit the respective uplink data is for the first user equipment and the second user equipment. In the uplink data transmission method according to the embodiment of the present invention, the uplink data is transmitted using the shared resource according to the priority order of the first user equipment and the second user equipment. Specifically, as in step S371 to step S373.
Step S371, obtaining the priority of the first user equipment using the shared resource from the first indication.
Step S372, obtaining the priority of the second user equipment using the shared resource from the second indication.
Step S373, when the priority of the shared resource used by the first user equipment is greater than the priority of the shared resource used by at least one second user equipment, sending uplink data of the first user equipment to the base station through the first shared resource block.
However, when the priority of the first user equipment using the shared resource is lower than the priority of at least one second user equipment using the shared resource, the first user equipment transmits uplink data of the first user equipment to the base station through a first shared resource block after at least one second user equipment transmits the uplink data to the base station through a second shared resource block;
wherein the second shared resource block is a shared resource block that can be used by the second user equipment and is determined in the shared resource by the second user equipment according to the second indication. And the second shared resource block may be a frequency band determined in the shared resource according to a frequency band in which the second dedicated resource is located.
Of course, it can be understood that, for the same user equipment group, when a plurality of user equipments configured with dedicated resources all have data transmission requirements, the manner in which the plurality of user equipments transmit uplink data using shared resources is not limited thereto. For example, the user equipments may transmit uplink data using the shared resource at the same time.
Specifically, for example, a UE1, a UE2, a UE3, and a UE4 included in a certain UE group are all UEs under a certain traffic type, have the same quality of service (QoS) requirement, and all of the UEs 1 to 4 are configured with dedicated resources, as shown in fig. 7. Then, when any one of the user equipments UE1 to UE4 has a data transmission request, an instruction to use the shared resource may be transmitted on the corresponding shared resource. Here, the shared resources of the group of user equipments may be commonly used by the UEs 1-4, and the number of used resources is equal.
When UE2 and UE4 indicate that the shared resource needs to be used, and UE1 and UE3 indicate that the shared resource does not need to be used, since the dedicated resource of UE2 is in the low frequency band and the dedicated resource of UE4 handles the high frequency band, UE2 may use the low frequency part of the shared resource to transmit uplink data and UE4 may use the high frequency part of the shared resource to transmit uplink data, as shown in fig. 8, thereby implementing simultaneous use of the shared resource by the UE.
In addition, in order to enable the shared resource to be used by the UE with the highest priority and having the data transmission requirement, preferably, after a certain UE uses the shared resource this time, the priority of the user equipment may be adjusted by itself, that is, the priority of the UE is reduced to the lowest.
For example, if three UEs, i.e., UE1, UE2, and UE3, are included in a UE group and all the three UEs are configured with dedicated resources in the order of priority that UE1 is lower than UE2 and UE2 is lower than UE3, as shown in fig. 9, after UE2 uses the shared resources to transmit uplink data, the priority of UE2 can be minimized, and specifically, the location of the dedicated resources of UE2 can be adjusted.
In addition, in some cases, the user equipment transmits more data, and further needs more shared resources. At this time, the ue may report Buffer Status Report (BSR) to the base station, and since the BSR includes the data amount in the ue buffer, the base station may deduce how much data the ue has to send and how much resources the ue needs through the BSR and the channel status reported by the ue. Therefore, after the base station receives the BSR sent by the ue, it determines that the shared resource allocated before cannot meet the uplink data sending requirement, and the base station may dynamically adjust the size of the shared resource, as shown in fig. 10.
In summary, the uplink data sending method according to the embodiment of the present invention achieves dynamic resource sharing while reducing uplink access delay, and effectively avoids resource waste.
Third embodiment
According to another aspect of the embodiments of the present invention, there is provided a method for transmitting uplink data, which is applied to a base station, as shown in fig. 11, the method includes:
step S111, configuring a proprietary resource for at least one user equipment in a user equipment group.
In the uplink data transmission method of the embodiment of the present invention, the base station needs to schedule a user equipment group, and the user equipment group includes a plurality of user equipments. For a plurality of user equipments in the user equipment group, the base station may configure corresponding dedicated resources for one or more or all user equipments in the group according to actual requirements.
When the base station schedules the user equipment group, one PDCCH only allocates one dedicated resource and one shared resource for the user equipment group, and if the base station wants to schedule the user equipment group again, the PDCCH needs to be retransmitted (the dedicated resource and the shared resource are indicated). Of course, the scheduling of the group of user equipments by the base station may also be similar to SPS scheduling, and a PDCCH allocates periodically existing resources (including dedicated resources and shared resources) for the group of users.
In addition, the base station may schedule the user equipment by transmitting a scheduling message to the user equipment. Wherein, the scheduling message can carry the usage priority of the user equipment to the shared resource. For a group of ues scheduled by the base station, the priority of the ues in the group that are not configured with the dedicated resource needs to be explicitly indicated in the scheduling message by the base station, but for the priority of the ues configured with the dedicated resource, the priority may be explicitly indicated in the scheduling message by the base station and may be determined by the location of the dedicated resource, for example, the ue in the lower frequency location is specified to have a higher priority. Of course, the base station is not limited to the frequency location of the dedicated resource according to the configured priority of the user equipment.
Step S113, when the ue configured with the dedicated resource sends, on the dedicated resource, an indication indicating that the ue configured with the dedicated resource uses a shared resource, receiving uplink data sent by the ue configured with the dedicated resource through the shared resource, where the shared resource is a shared resource of the ue group.
In the uplink data transmission method according to the embodiment of the present invention, in a user equipment group scheduled by a base station, there may be user equipments not configured with dedicated resources, and for the part of user equipments, since the priority level configured by the base station for the part of user equipments is lower than the priority level of the user equipments configured with dedicated resources, the part of user equipments need to use shared resources to transmit data when it is monitored that the user equipments configured with dedicated resources do not need to use shared resources.
For the user equipments which are not configured with the dedicated resources, the shared resources are used sequentially in a polling manner according to the respective priority order. However, in the polling process, if it is monitored that the other user equipment has transmitted the instruction to use the shared resource on the corresponding dedicated resource, the user equipment transmitting the instruction to use the shared resource can preferentially preempt the shared resource and transmit the uplink data.
Preferably, in order to make the shared resource available to the user equipment with the highest priority required for data transmission alone, the method further comprises:
and sending a priority reduction instruction to the user equipment which is configured with the special resource and sends the uplink data, so that the priority of the user equipment which is configured with the special resource and sends the uplink data is lower than the priority of the user equipment which is configured with the special resource and does not send the uplink data.
Preferably, the method further comprises:
