Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and a device for scheduling request resource allocation.
Background
With the availability of 5G (5-Generation, fifth Generation mobile communication technology) networks and the increase of connected devices and systems, the central terminal rate of the 5G network is high, and the edge terminal experience needs to be improved in order to provide a consistent terminal experience. Especially for high frequency bands, edge coverage needs to be enhanced urgently.
Multi-TRP (multiple Transmission/reception Point) provides services to edge terminals simultaneously by using multiple TRPs (Transmission Reference points), thereby enhancing the coverage of the edge terminals while increasing the rate.
When the terminal has uplink service to transmit, it sends SR (Scheduling Request) on the Scheduling Request Resource configured by the higher layer, the SR frequency domain occupies 1 PRB (Physical Resource Block), the time domain occupies 1 symbol wavelength, and the higher layer configures the SR Resource through the parameter Scheduling Request Resource configuration, including period and offset. Since the position for transmitting the SR is predefined by the base station, the SR itself does not need to carry the terminal device identifier and the base station identifier.
In a Mutli-TRP scenario, when multiple cells are jointly transmitted, SR resources are independently configured between base stations, and SR resources configured by the base stations for the same terminal are different, so that the terminal needs to reserve one SR resource for each cell for joint transmission, which causes a waste of PUCCH (Physical Uplink Control Channel) resources.
In summary, in the existing multi-cell joint transmission process, SR resources configured by each base station for the same terminal are different, and the terminal needs to reserve multiple SR resources, which causes waste of PUCCH resources.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. In the description of the present invention, the term "plurality" means two or more unless otherwise specified.
If the terminal has no uplink data to transmit, the base station does not need to allocate uplink resources for the terminal, otherwise, the resources are wasted. Therefore, the terminal needs to notify the base station whether there is uplink data to be transmitted, so that the base station can decide whether to allocate uplink resources to the terminal. Therefore, an uplink scheduling request mechanism is provided for LTE (Long Term Evolution).
The base station does not determine when the terminal needs to send uplink data, that is, does not determine when the terminal will send the SR, so the terminal notifies the base station whether the uplink resource is needed or not through the SR, the base station needs to detect whether the SR is reported or not on the allocated SR resource, and the terminal can only send the SR on the PUCCH. The base station needs to allocate a dedicated SR resource for each terminal to transmit the SR.
In a Mutli-TRP scene, SR resources are independently configured between base stations during multi-cell joint transmission, and SR resources configured by the base stations for the same terminal are different, so that the terminal needs to reserve one SR resource for each cell for joint transmission, which causes waste of PUCCH resources.
Therefore, in the embodiment of the present invention, the base station performing multipoint joint transmission configures SR resources for the terminal according to the same SR resource configuration information, so that SR resources configured for the terminal by multiple base stations performing multipoint joint transmission are the same, and since the SR resource configuration information received by the base station performing multipoint joint transmission is the same, SR resources configured for the terminal by each base station according to the SR resource configuration information are also the same, and the terminal only needs to reserve one SR resource for different base stations, so that resources of a PUCCH can be saved.
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With respect to the above scenario, the following describes an embodiment of the present invention in further detail with reference to the drawings of the specification.
As shown in fig. 1, a method for scheduling request resource allocation according to an embodiment of the present invention specifically includes the following steps:
step 100: a base station of multipoint joint transmission acquires Scheduling Request (SR) resource configuration information of a terminal;
step 101: and the base station of the multipoint joint transmission configures SR resources for the terminal according to the SR resource configuration information, so that the SR resources configured for the terminal by a plurality of base stations of the multipoint joint transmission are the same.
Through the scheme, the base station in multipoint joint transmission receives the SR resource configuration information of the terminal and configures the same SR resource for the terminal according to the received SR resource configuration information.
Wherein the SR resource configuration information comprises the period and offset of SR resources.
In the embodiment of the present invention, a base station for multipoint joint transmission acquires SR resource configuration information of a terminal, where the base station for multipoint joint transmission is a main serving base station or another base station except the main serving base station, and because the base stations for multipoint joint transmission are different, the situations that the base stations for multipoint joint transmission configure SR resources for the terminal according to the SR resource configuration information are also different, and the following is introduced in detail:
in case one, the base station of the multi-point joint transmission is the main serving base station.
In this embodiment of the present invention, if the base station for coordinated multi-point transmission is a main serving base station, the base station for coordinated multi-point transmission selects one of the predefined SR resource configurations, uses the information of the selected SR resource configuration as SR resource configuration information of the terminal, and then notifies other base stations for coordinated multi-point transmission of the SR resource configuration information.
As shown in fig. 2, the predefined SR resource configuration of terminal a is 4, and the resource configuration is respectively a scheduling request configurable resource 1: SR1 permission, scheduling request configurable resource 2: SR2 capability, scheduling request configurable resource 3: SR3 capability, scheduling request configurable resource 4: and SR4 permission, the base station performing multipoint joint transmission selects one SR resource configuration from the 4 SR resource configurations, and assuming that SR1 permission is selected, SR resource configuration information corresponding to SR1 permission is used as SR resource configuration information of the terminal a, and then the base station performing multipoint joint transmission notifies other base stations of SR resource configuration information.
Optionally, the base station of the multipoint joint transmission notifies the SR resource configuration information to other base stations of the multipoint joint transmission through an X2 signaling and/or a backhaul link.
As shown in fig. 3, the base stations performing the multi-point joint transmission for the terminal a are respectively the base station 1, the base station 2, and the base station 3, and after the base station 1 selects one SR resource configuration from the predefined SR resource configurations as SR resource configuration information of the terminal a, the base station 1 notifies the SR resource configuration information to the base stations 2 and 3 through X2 signaling.
In case two, the base station of the multi-point joint transmission is other base stations except the main service base station.
In the embodiment of the present invention, if the base station of the multipoint joint transmission is another base station except the primary serving base station, the another base station of the multipoint joint transmission acquires the SR resource configuration information of the primary serving base station.
Optionally, the other base stations in the multipoint joint transmission obtain SR resource configuration information of the primary serving base station through an X2 signaling and/or a backhaul link.
As shown in fig. 4, the multiple base stations performing multipoint joint transmission for the terminal B are respectively a base station 1, a base station 2, and a base station 3, and the main serving base station is a base station 0, where the base station 0 notifies the base station 1, the base station 2, and the base station 3 of SR resource configuration information of the base station 0 for the terminal B through a backhaul link, so that the base station 1, the base station 2, and the base station 3 configure the same SR resource for the terminal B.
It should be noted that the method for acquiring the SR resource configuration information by the base station through the multipoint joint transmission recited in the embodiment of the present invention is only an example, and any method for acquiring the SR resource configuration information by the base station through the multipoint joint transmission is applicable to the embodiment of the present invention.
When the terminal has uplink data to transmit, the terminal needs to notify the base station, so that the base station can determine whether to allocate uplink resources to the terminal. The base station does not determine when the terminal needs to transmit uplink data, i.e., does not determine when the terminal will transmit SR information. Therefore, the terminal needs to notify the base station whether uplink resources are needed through the SR resources configured by the base station, and the base station needs to detect whether SR information is reported on the allocated SR resources.
In the embodiment of the present invention, after configuring the same SR resource for the terminal by multiple base stations in multipoint joint transmission, receiving SR information sent by the terminal according to the SR resource configuration information, and after receiving SR information, at least one base station in the multiple base stations in multipoint joint transmission needs to send an uplink scheduling authorization request to the terminal.
There are many ways to select a base station that sends an uplink scheduling grant request to a terminal, and the following are some:
the selection mode is as follows: and selecting the base station with the best SR information receiving performance.
The receiving performance of the SR information refers to a signal-to-noise ratio of the SR information received by the base station and sent by the terminal, and the unit is dB (decibel), and a larger value indicates that the base station has better receiving performance for the SR information.
For example, the number of base stations performing the multipoint joint transmission for the terminal a is 4, which are respectively the base station 1, the base station 2, the base station 3, and the base station 4, where the SR information reception performance of the base station 1 for the terminal a is 0dB, the SR information reception performance of the base station 2 for the terminal a is 10dB, the SR information reception performance of the base station 3 for the terminal a is 20dB, and the SR information reception performance of the base station 4 for the terminal a is-5 dB, and it is known that the base station with the best SR information reception performance among the 4 base stations is the base station 3.
And a second selection mode: the base station with the earliest SR information arrival time is selected.
For example, there are 4 base stations performing multipoint joint transmission for terminal B, which are respectively base station 1, base station 2, base station 3, and base station 4, where the time for SR information sent by terminal B to reach base station 1 is 1ms, the time for SR information to reach base station 2 is 0.1ms, the time for SR information to reach base station 3 is 2ms, and the time for SR information to reach base station 4 is 0.1ms, and the base station with the earliest time for SR information to reach among the 3 base stations is base station 2 and base station 4, at which time at least one base station between base stations 2 and 4 may be selected to send an uplink scheduling grant request to terminal B. For example, the base station 2 and the base station 4 simultaneously transmit the uplink scheduling grant request to the terminal B, or compare the reception performance of the SR information transmitted by the base station 2 and the base station 4 to the terminal B, and select the base station with better reception performance of the SR information, and if the reception performance of the SR information transmitted by the base station 2 to the terminal B is 5dB and the reception performance of the SR information transmitted by the base station 4 to the terminal B is 3dB, select the base station 2 to transmit the uplink scheduling grant request to the terminal B.
It should be noted that the manner of selecting the base station that sends the uplink scheduling grant request to the terminal recited in the embodiment of the present invention is only an example, and any manner of selecting the base station that sends the uplink scheduling grant request to the terminal is applicable to the present invention.
