Background
A 5G (5 th Generation Mobile Communication Technology, fifth Generation Mobile Communication Technology) terminal UE transmits a resource configuration message to a base station through a PUCCH (Physical Uplink Control Channel).
Due to channel environment change or same-frequency signal interference, the reliability of PUCCH channel transmission is poor, and the reliability and timeliness of terminal UE feedback are affected. In the practical application process, the method of repeatedly sending the resource configuration message is generally adopted to improve the transmission reliability.
In the process of realizing the prior art, the inventor finds that:

Therefore, the problem of time delay caused by the repeated transmission of the PUCCH in the prior art can be seen, and the timeliness of the feedback of the terminal UE is still influenced by the existence of a large amount of time delay.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and 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 application.
Referring to fig. 1, the present application provides a method for transmitting a resource allocation message, including the following steps:
s110: the terminal UE takes a plurality of continuous time slots as elements from a first time to construct a first time slot set.
S120: the terminal UE distributes the first resource configuration message over the first set of time slots and sends it to the base station in the first set of time slots.
It can be understood that the resource configuration message described herein refers to a general name of a series of messages sent by the terminal UE to the base station through a Physical Uplink Control Channel (PUCCH). Generally, the resource configuration message may be characterized as a decoding result (Hybrid Automatic reQuest-ACK, HARQ-ACK), a Scheduling ReQuest (SR), or Channel State Information (CSI).
The first set of time slots includes a number of consecutive time slots starting from a first time instant. The time slot may be simply understood as a time region. Several consecutive slots will constitute the transmission time region of the PUCCH channel. In other words, the first set of slots may define a PUCCH channel.
In order to improve the reliability of the PUCCH channel transmission, the terminal UE repeatedly transmits the first resource configuration message to the base station in the time interval of the first time slot set. Specifically, the Slot mode is adopted, the first resource configuration message is distributed on the first time Slot set, and is sent to the base station in the first time Slot set until the base station receives the first resource configuration message. In other words, the first resource configuration message transmitted on any timeslot in the first set of timeslots is the same.
Further, in a specific implementation manner provided in the present application, the method for transmitting a resource configuration message further includes:
when the base station receives a first resource configuration message at any time slot in the first time slot set, the base station sends a first resource configuration message delivery message to the terminal UE;
and the terminal UE receives the first resource configuration message delivery message and stops sending the first resource configuration message to the base station.
It is to be understood that the base station receiving the first resource configuration message in any timeslot of the first timeslot set may be regarded as successfully receiving by the base station. And the base station which successfully receives the first resource configuration message sends a first resource configuration message delivery message to the terminal UE so as to call out the PUCCH to continue transmitting the first resource configuration message.
Specifically, according to the commonly used ratio of the 5G uplink Slot to the downlink Slot, a persistent uplink Slot is difficult to occur in the transmission process of the PUCCH channel. A plurality of downlink slots are often inserted between the uplink slots of N times, and if the downlink slots have scheduling information for the terminal UE, the base station may indicate, in a MAC CE (Control Element) or a dci (downlink Control indicator) of the scheduling information, that the first resource configuration message currently in progress of the terminal UE has been successfully received by using 1bit information.
When receiving a first resource configuration message delivery message, the terminal UE determines whether other resource configuration messages need to be sent currently;
if not, stopping sending the first resource configuration message to the base station so as to save transmission resources;
and if other resource configuration messages need to be sent, the terminal UE sends other resource configuration messages to the base station by using the second time slot set until the terminal UE receives the other resource configuration message delivery messages.
S130: and the terminal UE starts from a second time later than the first time, and constructs a second time slot set by taking a plurality of continuous time slots as elements.
S140: and the terminal UE distributes the second resource configuration message on the second time slot set and sends the second resource configuration message to the base station in the second time slot set.
It should be noted that the terminal UE may send the resource configuration message to the base station on multiple PUCCH channels. For the sake of brevity, only the first resource allocation message is transmitted on the PUCCH a channel and the second resource allocation message is transmitted on the PUCCH B channel, which should not be construed as a limitation to the scope of the invention.
It will be appreciated that the first resource configuration message is transmitted on the PUCCH a channel in the form of the terminal UE distributing the first resource configuration message over a first set of timeslots and transmitting to the base station in the first set of timeslots.
And the second resource configuration message is transmitted in a PUCCH B channel, and is expressed in that the terminal UE distributes the second resource configuration message on a second time slot set and sends the second resource configuration message to the base station in the second time slot set.
Wherein the second resource configuration message may be one of HARQ-ACK, SR, or CSI. The second set of time slots includes a number of consecutive time slots starting from a second time instant later than the first time instant.
S150: and when the first time slot set and the second time slot set have intersection time slots, determining the service types of the first resource allocation message and the second resource allocation message.
It is noted that the starting time slot of the second set of time slots is later than the starting time slot of the first set of time slots, which results in a possible intersection of elements between the first set of time slots and the second set of time slots. In other words, there may be an intersection time slot between the first set of time slots and the second set of time slots.
For example, if the base station has not received the first resource configuration message in the first timeslot set, or the terminal UE has not received the first resource configuration message delivery message sent by the base station, the first timeslot set is extended, and the first resource configuration message is repeatedly sent on the time slot in the extended first timeslot set. The extended first set of timeslots may have intersecting timeslots with the second set of timeslots.
The intersection time slot refers to that the terminal UE needs to send both the first resource allocation message and the second resource allocation message in the same time slot. And the slot is used as a basic unit of the PUCCH channel, and the terminal UE can only send one resource configuration message of the first resource configuration message or the second resource configuration message in the same slot, but cannot send the two resource configuration messages in the same slot.
In the prior art, if a plurality of resource configuration messages to be sent exist in the same time slot, terminal UE performs priority ordering according to the type of information data; then the terminal UE sends the information data with the highest priority in the time slot; the information data with lower priority is delayed by the terminal UE, or the terminal UE directly cancels the sending of the information data with lower priority. Specifically, the priority ordering rule in the prior art is HARQ-ACK > SR > CSI. Therefore, the transmission mode in the prior art brings the problem of time delay, and the existence of a large amount of time delay reduces the timeliness of the feedback of the terminal UE.
In the method, the service type of the resource configuration message is expanded in consideration of the time delay requirement of the resource configuration message and is divided into five types, namely low-delay decoding result HARQ-ACK, low-delay uplink scheduling request SR, high-delay decoding result HARQ-ACK, high-delay uplink scheduling request SR and channel state information CSI.
Specifically, in a specific implementation manner provided by the present application, the resource configuration message transmission method further includes:
establishing a mapping relation between the first resource configuration message and the service type in a preset service type registration table, and establishing a mapping relation between the second resource configuration message and the service type in the preset service type registration table;
the preset service type registry comprises a low-delay decoding result HARQ-ACK, a low-delay uplink scheduling request SR, a high-delay decoding result HARQ-ACK, a high-delay uplink scheduling request SR and channel state information CSI.
Further, when there is an intersection timeslot between the first timeslot set and the second timeslot set, determining the service type of the first resource allocation message and the service type of the second resource allocation message may be represented as:
determining the service type of the first resource configuration message according to the mapping relation between the first resource configuration message and the service type in a preset service type registration table;
and determining the service type of the second resource configuration message according to the mapping relation between the second resource configuration message and the service type in a preset service type registration table.
It should be noted that, by expanding the service type of the resource allocation message, the manner of allocating the resource allocation message on the intersection time slot can be more flexible, and the delay requirement can be more satisfied.
S160: and when the service types of the first resource allocation message and the second resource allocation message are different, the first resource allocation message is sent to the base station by a first transmission strategy in the intersection time slot.
It can be understood that, after determining the service types of the first resource allocation message and the second resource allocation message, it can be visually compared whether the service types of the first resource allocation message and the second resource allocation message are the same. And when the service types of the first resource allocation message and the second resource allocation message are different, the first resource allocation message is sent to the base station by using the first transmission strategy in the intersection time slot.
Wherein the first transmission strategy is represented by:
determining the service priority level of the first resource configuration message and the service priority level of the second resource configuration message;
and comparing the service priority level of the first resource allocation message with the service priority level of the second resource allocation message, and sending the resource allocation message with the highest service priority level to the base station in the intersection time slot.
The service priority levels are arranged in sequence from high to low as follows: low-delay decoding result HARQ-ACK, low-delay uplink scheduling request SR, high-delay decoding result HARQ-ACK, high-delay uplink scheduling request SR and channel state information CSI.
Of course, the service priority level has a mapping relation with the service type of the resource configuration message. The mapping relationship between the service priority level and the service type of the resource configuration message may be recorded in a preset service type registration table, so that determining the service priority level of the first resource configuration message and the service priority level of the second resource configuration message may be represented as:
determining the service priority level of the first resource configuration message according to the mapping relation between the first resource configuration message and the service type in the preset service type registration table and the mapping relation between the service priority level and the service type in the preset service type registration table;
and determining the service priority level of the second resource configuration message according to the mapping relation between the second resource configuration message and the service type in the preset service type registration table and the mapping relation between the service priority level and the service type in the preset service type registration table.
S170: and when the service types of the first resource allocation message and the second resource allocation message are the same, sending the first resource allocation message to the base station by using a second transmission strategy in the intersection time slot.
After the service types of the first resource configuration message and the second resource configuration message are determined, whether the service types of the first resource configuration message and the second resource configuration message are the same or not can be visually compared. And when the service types of the first resource allocation message and the second resource allocation message are the same, sending the first resource allocation message to the base station by using a second transmission strategy in the intersection time slot.
Wherein the second transmission policy is embodied as:
determining the time delay grade of the first resource configuration message and the time delay grade of the second resource configuration message;
when the time delay grades of the first resource allocation message and the second resource allocation message are the first time delay grade, the first resource allocation message with the earliest transmission moment is sent to the base station at the intersection time slot;
and when the time delay grades of the first resource allocation message and the second resource allocation message are the second time delay grade, alternately sending the first resource allocation message and the second resource allocation message to the base station in the intersection time slot.
Of course, the delay level has a mapping relationship with the service type of the resource configuration message. The mapping relationship between the delay level and the service type of the resource configuration message may be recorded in a preset service type registry, so that determining the delay level of the first resource configuration message and the delay level of the second resource configuration message may be represented as:
determining the time delay grade of the first resource configuration message according to the mapping relation between the first resource configuration message and the service type in the preset service type registration table and the mapping relation between the time delay grade and the service type in the preset service type registration table;
and determining the time delay grade of the second resource configuration message according to the mapping relation between the second resource configuration message and the service type in the preset service type registration table and the mapping relation between the time delay grade and the service type in the preset service type registration table.
Furthermore, according to the service delay requirement, the delay grades of the high-delay decoding result HARQ-ACK, the high-delay uplink scheduling request SR and the channel state information CSI are preset to be a first delay grade; and presetting the delay grades of the low-delay decoding result HARQ-ACK and the low-delay uplink scheduling request SR as a second delay grade.
When the delay levels of the first resource allocation message and the second resource allocation message are the first delay level, the first resource allocation message with the earliest transmission time is sent to the base station at the intersection time slot, which can be simply understood as a first-come and later-come transmission strategy.
When the delay levels of the first resource allocation message and the second resource allocation message are the second delay level, the first resource allocation message and the second resource allocation message are alternately sent to the base station at the intersection time slot, which may be simply exemplified as:
in the case of several intersection slots, several intersection slots may be used as elements to form an intersection slot set. And then sequencing a plurality of intersection time slots in the intersection time slot set by using the time stamps, sending a first resource allocation message on the intersection time slot of the odd-numbered sequence, and sending a second resource allocation message on the intersection time slot of the even-numbered sequence, so that the first resource allocation message and the second resource allocation message are alternately sent.
The following describes a specific implementation process of the resource allocation message transmission method provided by the present application:
the terminal UE takes a plurality of continuous time slots as elements from a first time to construct a first time slot set. The terminal UE distributes the first resource configuration message on the first time slot set and repeatedly sends the first resource configuration message to the base station through PUCCH A in the first time slot set.
If the base station does not receive the first resource allocation message in the first time slot set all the time, or the terminal UE does not receive the first resource allocation message delivery message sent by the base station all the time, the terminal UE prolongs the first time slot set and repeatedly sends the first resource allocation message to the base station on the time slot in the prolonged first time slot set.
And if the base station receives the first resource configuration message in the first time slot set or any time slot in the extended first time slot set, the base station sends a first resource configuration message delivery message to the terminal UE.
When the terminal UE receives the first resource configuration message delivery message, whether a second resource configuration message needs to be sent currently is determined. If not, the first resource configuration message is stopped from being sent to the base station so as to save transmission resources. And if the second resource configuration message needs to be sent, the terminal UE sends other resource configuration messages to the base station by using the second time slot set until the terminal UE receives the second resource configuration message delivery message.
If the terminal UE has a second resource allocation message to send in the first timeslot set or the extended first timeslot set, the terminal UE will be involved in sending the first resource allocation message or the second resource allocation message on the intersection timeslot.
Specifically, a mapping relationship between the first resource configuration message and the service type in a preset service type registration table, a mapping relationship between the second resource configuration message and the service type in the preset service type registration table, a mapping relationship between the service priority level and the service type in the preset service type registration table, and a mapping relationship between the delay level and the service type in the preset service type registration table are established.
And when the first time slot set and the second time slot set have intersection time slots, the terminal UE determines whether a first resource allocation message sending message sent by the base station is received.

In summary, the resource allocation message transmission method provided by the present application enables the allocation of the resource allocation message to be more flexible by expanding the service type of the resource allocation message; by comparing the service types of the first resource configuration message and the second resource configuration message, the terminal UE can execute two transmission strategies which are more intelligent and meet the time delay requirement better.
It should be further emphasized that the single-carrier scenario is a mainstream networking manner at present, and no other carrier is provided for auxiliary transmission in the single-carrier scenario. The resource allocation message transmission method provided by the application is used for transmitting and allocating the resource allocation messages on the intersection time slots, and still adopts the main carrier for transmission. Therefore, the resource allocation message transmission method is suitable for a single carrier scene or a multi-carrier scene, the first resource allocation message and the second resource allocation message are alternately sent to the base station at the intersection time slot, the problem of a large amount of time delay caused by the PUCCH under the time slot conflict can be solved, and the timeliness of the feedback of the terminal UE is improved.
Referring to fig. 2, in order to support the resource allocation message transmission method, the present application further provides a resource allocation message transmission system 100, which includes:
a terminal UE11, configured to start from a first time, and construct a first time slot set by using a plurality of consecutive time slots as elements; the base station further comprises means for distributing the first resource configuration message over a first set of time slots and transmitting to the base station in the first set of time slots; the time slot aggregation module is also used for constructing a second time slot aggregation by taking a plurality of continuous time slots as elements from a second time later than the first time; the base station is also used for distributing the second resource configuration message on the second time slot set and sending the second resource configuration message to the base station in the second time slot set;
the allocation module 12 is configured to determine the service types of the first resource allocation message and the second resource allocation message when an intersection timeslot exists between the first timeslot set and the second timeslot set; the base station is also used for sending the first resource configuration message to the base station by a first transmission strategy in the intersection time slot when the service types of the first resource configuration message and the second resource configuration message are different; and the base station is further configured to send the first resource allocation message to the base station with the second transmission policy at the intersection time slot when the first resource allocation message and the second resource allocation message have the same service type.
It can be understood that the resource configuration message described herein refers to a general term of a series of messages sent by terminal UE11 to the base station through a Physical Uplink Control Channel (PUCCH). Generally, the resource configuration message may be characterized as a decoding result (Hybrid Automatic reQuest-ACK, HARQ-ACK), a Scheduling ReQuest (SR), or Channel State Information (CSI).
The first set of time slots includes a number of consecutive time slots starting from a first time instant. The time slot may be simply understood as a time region. Several consecutive slots will constitute the transmission time region of the PUCCH channel. In other words, the first set of slots may define a PUCCH channel.
To improve the reliability of the PUCCH channel transmission, terminal UE11 repeatedly sends the first resource configuration message to the base station in the time interval of the first set of time slots. Specifically, the terminal UE11 distributes the first resource allocation message on the first time Slot set in a Slot manner, and sends the first resource allocation message to the base station in the first time Slot set until the base station receives the first resource allocation message. In other words, the first resource configuration message transmitted on any slot in the first set of slots is the same.
Further, in a specific embodiment provided in the present application, the resource configuration message transmission system 100 further includes:
the base station 13 is configured to receive the first resource allocation message in any time slot of the first set of time slots, and send a first resource allocation message delivery message to the terminal UE 11.
The terminal UE11 is further configured to receive the first resource allocation message delivery message, and stop sending the first resource allocation message to the base station 13.
It is to be understood that the base station 13 receiving the first resource configuration message in any time slot of the first set of time slots may be regarded as the base station 13 successfully receiving. The base station 13 that successfully receives the first resource configuration message will send a first resource configuration message delivery message to the terminal UE11 to terminate the PUCCH channel to continue transmitting the first resource configuration message.
Specifically, according to the commonly used ratio of the 5G uplink Slot to the downlink Slot, a persistent uplink Slot is difficult to occur in the transmission process of the PUCCH channel. A plurality of downlink slots are often inserted between the N uplink slots, and if the downlink slots have scheduling information issued for the terminal UE11, the base station 13 may use 1-bit information in a MAC CE (Control Element) or a dci (downlink Control indicator) of the scheduling information to indicate that the first resource configuration message currently being received by the terminal UE11 is successfully received.
When the terminal UE11 receives the first resource allocation message delivery message, it is determined whether there are other resource allocation messages to be sent currently by the terminal UE 11;
if not, stopping sending the first resource allocation message to the base station 13 to save transmission resources;
if there are other resource allocation messages to send, terminal UE11 sends other resource allocation messages to base station 13 in the second set of timeslots until terminal UE11 receives the other resource allocation message delivery message.
It is noted that terminal UE11 may send a resource configuration message to base station 13 on multiple PUCCH channels. For the sake of brevity, only the first resource allocation message is transmitted on the PUCCH a channel and the second resource allocation message is transmitted on the PUCCH B channel, which should not be construed as a limitation to the scope of the invention.
It will be appreciated that the first resource configuration message is transmitted on the PUCCH a channel in the form of the terminal UE11 distributing the first resource configuration message over a first set of time slots and transmitting to the base station 13 in the first set of time slots.
The second resource configuration message is transmitted on the PUCCH B channel as terminal UE11 distributes the second resource configuration message over the second set of slots and sends to base station 13 in the second set of slots.
Wherein the second resource configuration message may be one of HARQ-ACK, SR, or CSI. The second set of time slots includes a number of consecutive time slots starting from a second time instant later than the first time instant.
It is further noted that the starting time slot of the second set of time slots is later than the starting time slot of the first set of time slots, which results in a possible intersection of elements between the first set of time slots and the second set of time slots. In other words, there may be an intersection time slot between the first set of time slots and the second set of time slots.
For example, if the base station 13 has not received the first resource allocation message in the first time slot set, or the terminal UE11 has not received the first resource allocation message delivery message sent by the base station 13, the first time slot set is extended, and the first resource allocation message is repeatedly sent on the time slot in the extended first time slot set. The extended first set of timeslots may have intersecting timeslots with the second set of timeslots.
The intersection time slot refers to that, in the same time slot, the terminal UE11 needs to send both the first resource allocation message and the second resource allocation message. And the slot is a basic unit of the PUCCH channel, and the terminal UE11 can only transmit one resource configuration message of the first resource configuration message or the second resource configuration message in the same slot, but cannot transmit the two resource configuration messages in the same slot.
In the prior art, if a plurality of resource configuration messages to be sent exist in the same time slot, terminal UE performs priority ordering according to the type of information data; then the terminal UE sends the information data with the highest priority in the time slot; the information data with lower priority is delayed by the terminal UE, or the terminal UE directly cancels the sending of the information data with lower priority. Specifically, the priority ordering rule in the prior art is HARQ-ACK > SR > CSI. Therefore, the transmission mode in the prior art brings the problem of time delay, and the existence of a large amount of time delay reduces the timeliness of the feedback of the terminal UE.
In the method, the service type of the resource configuration message is expanded in consideration of the time delay requirement of the resource configuration message, and the service type of the resource configuration message is divided into five types, namely low-time-delay decoding result HARQ-ACK, low-time-delay uplink scheduling request SR, high-time-delay decoding result HARQ-ACK, high-time-delay uplink scheduling request SR and channel state information CSI.
Specifically, in an embodiment provided in the present application, the allocating module 12 is further configured to:
establishing a mapping relation between the first resource configuration message and the service type in a preset service type registration table and a mapping relation between the second resource configuration message and the service type in the preset service type registration table;
the preset service type registration table comprises a low-delay decoding result HARQ-ACK, a low-delay uplink scheduling request SR, a high-delay decoding result HARQ-ACK, a high-delay uplink scheduling request SR and channel state information CSI.
Further, when there is an intersection timeslot between the first timeslot set and the second timeslot set, the allocating module 12 determines the service type of the first resource configuration message and the second resource configuration message, which may be represented as:
the allocation module 12 determines the service type of the first resource allocation message according to the mapping relationship between the first resource allocation message and the service type in the preset service type registration table;
the allocation module 12 determines the service type of the second resource allocation message according to the mapping relationship between the second resource allocation message and the service type in the preset service type registration table.
It should be noted that, by expanding the service type of the resource allocation message, the manner of allocating the resource allocation message on the intersection time slot can be more flexible, and the delay requirement can be more satisfied.
Further, after the allocation module 12 determines the service types of the first resource allocation message and the second resource allocation message, it may be visually compared whether the service types of the first resource allocation message and the second resource allocation message are the same. When the service types of the first resource allocation message and the second resource allocation message are different, the allocating module 12 sends the first resource allocation message to the base station 13 in the intersection time slot by using the first transmission policy.
Wherein the first transmission strategy is represented by:
determining the service priority level of the first resource configuration message and the service priority level of the second resource configuration message;
and comparing the service priority level of the first resource allocation message with the service priority level of the second resource allocation message, and sending the resource allocation message with the highest service priority level to the base station 13 in the intersection time slot.
The service priority levels are arranged in sequence from high to low as follows: low-delay decoding result HARQ-ACK, low-delay uplink scheduling request SR, high-delay decoding result HARQ-ACK, high-delay uplink scheduling request SR and channel state information CSI.
Of course, the service priority level has a mapping relation with the service type of the resource configuration message. The allocation module 12 may record a mapping relationship between the service priority level and the service type of the resource allocation message in a preset service type registration table, so that determining the service priority level of the first resource allocation message and the service priority level of the second resource allocation message may be represented as:
determining the service priority level of the first resource configuration message according to the mapping relation between the first resource configuration message and the service type in the preset service type registration table and the mapping relation between the service priority level and the service type in the preset service type registration table;
and determining the service priority level of the second resource configuration message according to the mapping relation between the second resource configuration message and the service type in the preset service type registration table and the mapping relation between the service priority level and the service type in the preset service type registration table.
Further, after the allocation module 12 determines the service types of the first resource allocation message and the second resource allocation message, it may be visually compared whether the service types of the first resource allocation message and the second resource allocation message are the same. When the service types of the first resource allocation message and the second resource allocation message are the same, the allocating module 12 sends the first resource allocation message to the base station 13 in the intersection time slot by using the second transmission policy.
Wherein the second transmission policy is embodied as:
determining the time delay grade of the first resource configuration message and the time delay grade of the second resource configuration message;
when the delay levels of the first resource allocation message and the second resource allocation message are the first delay level, the first resource allocation message with the earliest transmission time is sent to the base station 13 at the intersection time slot;
and when the delay levels of the first resource allocation message and the second resource allocation message are the second delay level, alternately sending the first resource allocation message and the second resource allocation message to the base station 13 at the intersection time slot.
Of course, the delay level has a mapping relationship with the service type of the resource configuration message. The allocation module 12 may record a mapping relationship between the delay level and the service type of the resource configuration message in a preset service type registry, so that determining the delay level of the first resource configuration message and the delay level of the second resource configuration message may be represented as:
determining the time delay grade of the first resource configuration message according to the mapping relation between the first resource configuration message and the service type in a preset service type registration table and the mapping relation between the time delay grade and the service type in the preset service type registration table;
and determining the time delay grade of the second resource configuration message according to the mapping relation between the second resource configuration message and the service type in the preset service type registration table and the mapping relation between the time delay grade and the service type in the preset service type registration table.
Furthermore, according to the service delay requirement, the delay grades of the high-delay decoding result HARQ-ACK, the high-delay uplink scheduling request SR and the channel state information CSI are preset to be a first delay grade; and presetting the delay grades of the low-delay decoding result HARQ-ACK and the low-delay uplink scheduling request SR as a second delay grade.
When the delay levels of the first resource allocation message and the second resource allocation message are the first delay level, the first resource allocation message with the earliest transmission time is sent to the base station 13 at the intersection time slot, which can be simply understood as a first-come and last-come transmission strategy.
When the delay levels of the first resource allocation message and the second resource allocation message are the second delay level, the first resource allocation message and the second resource allocation message are alternately sent to the base station 13 at the intersection time slot, which may be simply exemplified as:
in the case of several intersection slots, several intersection slots may be used as elements to form an intersection slot set. And then sequencing a plurality of intersection time slots in the intersection time slot set by using the time stamps, sending a first resource allocation message on the intersection time slot of the odd-numbered sequence, and sending a second resource allocation message on the intersection time slot of the even-numbered sequence, so that the first resource allocation message and the second resource allocation message are alternately sent.
The following describes a specific implementation process of the resource allocation message transmission system 100 provided in the present application:
the terminal UE11 constructs a first set of time slots starting from a first time instant with consecutive time slots as elements. Terminal UE11 distributes the first resource configuration message over the first set of time slots and repeatedly sends the first resource configuration message to base station 13 over PUCCH a in the first set of time slots.
If the base station 13 has not received the first resource allocation message in the first timeslot set, or the terminal UE11 has not received the first resource allocation message delivery message sent by the base station 13, the terminal UE11 extends the first timeslot set, and repeatedly sends the first resource allocation message to the base station 13 on the timeslot in the extended first timeslot set.
If the base station 13 receives the first resource allocation message in any time slot of the first time slot set or the extended first time slot set, the base station 13 sends a first resource allocation message delivery message to the terminal UE 11.
When terminal UE11 receives the first resource configuration message, it is determined whether terminal UE11 currently has a second resource configuration message to send. If not, the first resource allocation message is stopped from being sent to the base station 13, so as to save transmission resources. If there is a second resource allocation message to send, terminal UE11 sends other resource allocation messages to base station 13 in the second set of timeslots until terminal UE11 receives the second resource allocation message delivery message.
If the terminal UE11 has a second resource allocation message to send in the first timeslot set or the extended first timeslot set, the allocation module 12 will be involved in sending the first resource allocation message or the second resource allocation message on the intersection timeslot.
Specifically, the allocation module 12 establishes a mapping relationship between the first resource allocation message and the service type in the preset service type registration table, a mapping relationship between the second resource allocation message and the service type in the preset service type registration table, a mapping relationship between the service priority level and the service type in the preset service type registration table, and a mapping relationship between the delay level and the service type in the preset service type registration table.
When there is an intersection time slot between the first time slot set and the second time slot set, the terminal UE11 determines whether the first resource allocation message delivery message sent by the base station 13 is received.
If the terminal UE11 does not receive the first resource allocation message delivery message, the allocation module 12 determines the service type of the first resource allocation message according to the mapping relationship between the first resource allocation message and the service type in the preset service type registry. The allocation module 12 determines the service type of the second resource allocation message according to the mapping relationship between the second resource allocation message and the service type in the preset service type registration table.
When the service types of the first resource allocation message and the second resource allocation message are different, the allocation module 12 determines the service priority level of the first resource allocation message according to the mapping relationship between the first resource allocation message and the service type in the preset service type registry and the mapping relationship between the service priority level and the service type in the preset service type registry. The allocation module 12 determines the service priority level of the second resource allocation message according to the mapping relationship between the second resource allocation message and the service type in the preset service type registration table, and the mapping relationship between the service priority level and the service type in the preset service type registration table. Then, the allocation module 12 compares the service priority level of the first resource allocation message and the service priority level of the second resource allocation message according to the priority level sequence of "low-delay decoding result HARQ-ACK > low-delay uplink scheduling request SR > high-delay uplink scheduling request SR > channel state information CSI", and sends the resource allocation message with the highest service priority level to the base station 13 at the intersection time slot.
When the service types of the first resource allocation message and the second resource allocation message are the same, the allocation module 12 determines the delay level of the first resource allocation message according to the mapping relationship between the first resource allocation message and the service type in the preset service type registry and the mapping relationship between the delay level and the service type in the preset service type registry. The allocation module 12 determines the delay level of the second resource allocation message according to the mapping relationship between the second resource allocation message and the service type in the preset service type registration table and the mapping relationship between the delay level and the service type in the preset service type registration table. When the delay levels of the first resource allocation message and the second resource allocation message are the first delay level, the allocating module 12 sends the first resource allocation message with the earliest transmission time to the base station 13 at the intersection time slot. When the delay levels of the first resource allocation message and the second resource allocation message are the second delay level, the allocation module 12 alternately sends the first resource allocation message and the second resource allocation message to the base station 13 at the intersection time slot.
When the first time slot set and the second time slot set have an intersection time slot, the terminal UE11 determines that the first resource allocation message delivery message sent by the base station 13 is received, and sends the second resource allocation message to the base station 13 at the intersection time slot.
To sum up, the resource allocation message transmission system 100 provided in the present application expands the service type of the resource allocation message, so that the allocation of the resource allocation message is more flexible; by comparing the service types of the first resource allocation message and the second resource allocation message, the terminal UE11 can execute two more intelligent transmission strategies that meet the delay requirement better.
It should be further emphasized that the single-carrier scenario is a mainstream networking manner at present, and no other carrier is provided for auxiliary transmission in the single-carrier scenario. The resource allocation message transmission system 100 provided by the present application performs transmission allocation on resource allocation messages on intersecting time slots, and still uses a main carrier for transmission. Therefore, the resource allocation message transmission system 100 provided by the present application is suitable for a single carrier scenario or a multi-carrier scenario, and the first resource allocation message and the second resource allocation message are alternately sent to the base station 13 at an intersection time slot, so that a large amount of delay problems caused by PUCCH channel under time slot collision can be reduced, and timeliness of feedback of the terminal UE11 is improved.
