This Application is a National Stage of International Application No PCT/CN2020/071135, filed on Jan. 9, 2020, which claims priority to Chinese Application No. 201910028755.5, filed on Jan. 11, 2019, both of which are incorporated by reference herein.
The present disclosure relates to the field of communication technology, and in particular to an uplink transmission resource selection method, a terminal, and a storage medium.
As communication technology is developing continuously, wireless communication has evolved from 2G voice interaction to 5G New Radio (NR) dual connectivity communication mode. In Time Sensitive Networking (TSN), data packets in transmission have a fixed latency and transmission period. NR technology can be used to support network services in which data packets are transmitted in deterministic periods. The RAN1#95 meeting pointed out that Bandwidth Part (BWP) resources of a serving cell may be used to configure and activate a plurality of resource configuration information for supporting a plurality of different services or communication types, and can also enhance data transmission reliability and reduce data transmission latency.
However, uplink resources corresponding to the configuration information may overlap or partially overlap in a time domain, which causes some data to fail to be transmitted in a current slot, thereby increasing data transmission latency. For some services with higher latency requirements, such as a ultra-reliable low-latency communication (URLLC) service, such a problem of failing to meet a demand for service transmission may occur.
In view of the above, the present disclosure provides a selection method for uplink transmission resources, terminal, and storage medium, which can meet the service demand with higher latency requirements.
According to one aspect of the present disclosure, there is provided a method for selecting uplink resources, comprising:
receiving at least one piece of uplink scheduling information;
determining, based on the uplink scheduling information, transmission priorities of the uplink resources indicated by the uplink scheduling information; and
selecting, based on the transmission priorities of the uplink resources, an uplink resource for data transmission.
According to another aspect of the present disclosure, there is provided a terminal, comprising a processor; and a memory configured to store instructions executable by the processor, wherein the processor is configured to execute the methods described above.
According to another aspect of the present disclosure, there is provided a non-transitory computer-readable medium storing computer program instructions, wherein the computer program instructions, when executed by a processor, implement the methods described above.
The drawings, which are incorporated in and constitute part of the specification, together with the description, illustrate exemplary embodiments, features and aspects of the present disclosure and serve to explain the principles of the present disclosure.
Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail with reference to the drawings. The same reference numerals in the drawings represent parts having the same or similar functions. Although various aspects of the embodiments are shown in the drawings, it is unnecessary to proportionally draw the drawings unless otherwise specified.
Herein the term “exemplary” means “used as an instance or example, or explanatory.” An “exemplary” embodiment given herein is not necessarily construed as being superior to or better than other embodiments.
Numerous details are given in the following embodiments for the purpose of better explaining the present disclosure. It should be understood by a person skilled in the art that the present disclosure can still be realized even without some of those details. In some of the embodiments, methods, means, units and circuits that are known to a person skilled in the art are not described in detail so that the principle of the present disclosure become apparent.
In embodiments of the present disclosure, the terminal can receive at least one piece of uplink scheduling information, determine, based on the uplink scheduling information, transmission priorities of the uplink resources indicated by the uplink scheduling information, and select, based on the transmission priorities of the uplink resources, an uplink resource for data transmission. As a result, the terminal may select an uplink resource from the uplink resources indicated in the uplink scheduling information for data transmission, and transmit corresponding data using the selected uplink resource. If uplink resources overlap or partially overlap in a time domain, the terminal can select an uplink resource for current transmission based on the transmission priorities, thereby meeting the service data transmission demand with higher latency requirements
Other features and aspects of the present disclosure will become clear from the following detailed description of exemplary embodiments with reference to the accompanying drawings
In embodiments of the present disclosure, the terminal receives at least one piece of uplink scheduling information, and determines, based on the uplink scheduling information, transmission priorities of uplink resources indicated by the uplink scheduling information. Thus, the terminal may select, based on the transmission priorities of the uplink resources, an uplink resource for data transmission. Even when uplink resources corresponding to configuration information overlap or partially overlap in a time domain, the terminal can preferentially transmit data having a higher priority to meet a service data transmission demand with higher latency requirements. Herein uplink scheduling information may include semi-persistent scheduling information and dynamic scheduling information. The semi-persistent scheduling information can be used to support service in which data is transmitted in a determined period. Embodiments of the present disclosure can use semi-persistent scheduling information to schedule data transmission of service having determined periods.
In the related art, when uplink resources corresponding to semi-persistent scheduling information overlap or partially overlap with uplink resources corresponding to dynamic scheduling information in a time domain, the latter will be cover the former. If the uplink resources corresponding to dynamic scheduling information are used to transmit dserviceata in service data having a lower priority, such as enhanced Mobile Broadband (eMBB) service data, and the uplink resources corresponding to the semi-persistent scheduling information are used to transmit service data having a higher priority, such as URLLC service data, then the eMBB service data is transmitted in a current slot, which cannot timely transmit the URLLC service data. However, the URLLC service data generally requires a higher latency requirement. If the URLLC service cannot be transmitted timely, such a problem of failing to meet a demand for service transmission may exist. The scheme for selecting uplink transmission resources provided by the present disclosure can avoid the problem of failing to meet a demand for service transmission due to a delayed transmission.
The selection scheme for uplink transmission resources provided by the present disclosure will be described in detail with reference to the drawings.
The method includes receiving at least one uplink grant in 101.
A terminal may receive uplink scheduling information transmitted from the base station after establishing a communication connection with a base station. There is at least one piece of the uplink scheduling information herein, where one piece of the uplink scheduling information may indicate one of the uplink resources. The terminal may acquire the uplink scheduling information in Downlink Control Information (DCI) that is transmitted from the base station by an uplink dynamic scheduling mechanism. The uplink scheduling information may be used to indicate a resource configuration of uplink transmission on a physical uplink shared channel (PUSCH), so the terminal may configure an uplink resource based on the uplink scheduling information. The uplink scheduling information acquired via DCI may be referred to as dynamic scheduling information. Also, the terminal may acquire an uplink scheduling information in radio resource control (RRC) information, and the uplink scheduling information acquired via the RRC information is referred to as semi-persistent scheduling information. The semi-persistent scheduling information may be used to support a service in which data is transmitted in a determined period. The semi-persistent scheduling information may include type-1 semi-persistent scheduling information and type-2 semi -persistent scheduling information. The type-1 semi-persistent scheduling information may be acquired in the RRC information, and the type-2 semi-persistent scheduling information may be acquired in the RRC information and/or the DCI.
The method for selecting uplink transmission resources includes determining, based on the uplink scheduling information, transmission priorities of the uplink resources indicated by the uplink scheduling information in 102.
After acquiring at least one piece of uplink scheduling information, the terminal may determine, based on resource allocation information included in each piece of the uplink scheduling information, an uplink resource corresponding to the piece of the uplink scheduling information, and then determine, based on the piece of the uplink scheduling information, transmission priorities of the uplink resources. In response to receiving a plurality of uplink scheduling information, the terminal may determine multiple uplink resources based on the plurality of uplink scheduling information, with one piece of the uplink scheduling information indicates one of the uplink resources. Since the terminal corresponds to one uplink resource in one time domain, the terminal can select an uplink resource for current data transmission from the multiple uplink resources, thereby implementing an optimal allocation of the uplink resources.
The method for selecting uplink transmission resources includes selecting, based on the transmission priorities of the uplink resources, an uplink resource for data transmission in 103.
After determining the transmission priorities of the uplink resources indicated by the uplink scheduling information, the terminal may select an uplink resource for data transmission based on the transmission priorities. It should be noted that the terminal may select one or more uplink resources for data transmission in selecting an uplink resource for data transmission. When one uplink resource for data transmission is selected, the terminal may select an uplink resource having a highest transmission priority for data transmission. Selecting an uplink resource for data transmission may be interpreted as using a selected uplink resource to transmit data without using an unselected uplink resource to transmit the data. Alternatively, selecting an uplink resource for data transmission may be interpreted as using a selected uplink resource to transmit data while using an unselected uplink resource to perform other service. Particular implementation is not limited thereto.
With the method for selecting uplink resources provided in the foregoing embodiment, the terminal can determine transmission priorities of uplink resources indicated by uplink scheduling information. Thus, when uplink resources overlap or partially overlap in a time domain, the terminal can preferentially transmit data having a higher priority, thereby meeting a service data transmission demand with higher latency requirements.
Based on the method described above, embodiments of the present disclosure also provide a process for determining transmission priorities of uplink resources.
determining a target logical channel having the highest priority, among logical channels where data to be transmitted currently exists in 201;
determining, based on a transmission-format configuration parameter of the target logical channel and the uplink scheduling information, an uplink resource among uplink resources indicated by the uplink scheduling information that matches the transmission-format configuration parameter in 202; and
determining, based on a preset resource selection condition, a transmission priority of the uplink resource that matches the transmission-format configuration parameter in 203.
There may be one or more Logical Channels (LCH) where data to be transmitted currently exists herein. If there are multiple logical channels where data to be transmitted exists, the terminal may select a logical channel among the multiple logical channels that has a highest priority as the target logical channel. A logical channel has a corresponding transmission-format configuration parameter that may include, but is not limited to, subcarrier spacing (SCS) and physical uplink shared channel duration (PUSCH-Duration). There may be multiple transmission -format configuration parameters of each logical channel. For example, each logical channel may have a corresponding SCS list and a maximum PUSCH-Duration, therein any transmission-format configuration parameter is eligible for a requirement of the logical channel. The terminal may match a transmission-format configuration parameter of the target logical channel with at least one piece of the uplink scheduling information. For example, the terminal determines one or more uplink resources among uplink resources indicated by the uplink scheduling information that match a transmission-format configuration parameter of the target logical channel by comparing SCS and PUSCH-Duration of the target logical channel with SCS and PUSCH-Duration in each piece of the uplink scheduling information.
The preset resource selection condition may include at least one of transmission latency of an uplink resource or transmission reliability of an uplink resource. Optionally, the transmission latency of an uplink resource may be characterized by the PUSCH-Duration or end time of the uplink resource. The transmission reliability of an uplink resource may be characterized by an MCS index value or a type of Radio Network Temporary Identifiers (RNTI).
For instance, in response to an uplink resource having shorter transmission latency, the terminal may set a higher transmission priority of the uplink resource. For example, the highest transmission priority may be set for an uplink resource that has the shortest PUSCH-Duration or earlier end time of an uplink resource. In response to an uplink resource having higher transmission reliability, the terminal may set a higher transmission priority of the uplink resource. For example, the highest transmission priority may be set for an uplink resource that has the smallest MCS index value, or an uplink resource indicated by an uplink scheduling information that is scrambled by a Modulation and Coding Scheme-Radio Network Temporary Identifier (MCS-RNTI) or Configured Scheduling-Radio Network Temporary Identifier (CS-RNTI).
In response to the unlink scheduling information being dynamic scheduling information, determining transmission priorities of uplink resources includes:
determining, based on indication information carried by the uplink scheduling information, a target logical channel indicated by the indication information in 301; and
determining, based on a priority of the target logical channel, the transmission priorities of uplink resources indicated by the uplink scheduling information in 302.
Herein, the terminal may receive a plurality of uplink scheduling information transmitted from the base station, with each piece of the uplink scheduling information indicating one of the uplink resources, and the plurality of uplink scheduling information corresponding to multiple uplink resources. When any one piece of the uplink scheduling information is dynamic scheduling information, the terminal may determine, based on indication information carried in the uplink scheduling information, one or more target logical channels indicated by the indication information. The indication information may be indication information that is added to the uplink scheduling information transmitted from the base station to the terminal for indicating a logical channel prioritized for data transmission. Embodiments of the present disclosure do not limit the number of bits of the indication information. The number of bits of the indication information may be proportional to accuracy at which the indication information is capable of the indication—that is, the higher the accuracy of the indication, the more the number of bits of the indication information may be. For example, if each terminal may configure N logical channels, and the N logical channels may be divided into M categories based on a descending order of the priority, then the number of bits of the indication information may be a result of rounding log2M+1. N and M are each a positive integer and N is a multiple of M.
In determining the transmission priorities of uplink resources indicated by uplink scheduling information, the terminal may use priorities of the target logical channels as the transmission priorities of the uplink resources indicated by the uplink scheduling information.
In response to the uplink scheduling information being semi-persistent scheduling information, determining the transmission priorities of the uplink resources includes:
determining, based on transmission-format configuration parameters of logical channels and the uplink scheduling information, first logical channels among the logical channels the transmission-format configuration parameters of which match the uplink scheduling information in 311;
determining, based on the uplink scheduling information and service transmission modes of the first logical channels, a target logical channel among the first logical channels the service transmission mode of which matches the scheduling information in 312; and
determining, based on a priority of the target logical channel, the transmission priorities of the uplink resources indicated by the uplink scheduling information in 313.
Optionally, in response to the uplink scheduling information being type-1 semi-persistent scheduling information in determining the first logical channels among the logical channels the transmission-format configuration parameters of which match the uplink scheduling information, the terminal may acquire the transmission-format configuration parameters of the uplink resources indicated by the uplink scheduling information in Radio Resource Control (RRC) configuration information transmitted from the base station, and then determine, based on the transmission-format configuration parameters of the logical channels and the transmission-format configuration parameters of the uplink resources, the first logical channels among the logical channels the transmission-format configuration parameters of which match the transmission-format configuration parameters of the uplink resources.
Optionally, in response to the uplink scheduling information being type-2 semi-persistent scheduling information in determining the first logical channels among the logical channels the transmission-format configuration parameters of which match the uplink scheduling information, the terminal may acquire the transmission-format configuration parameters of the uplink resources in Radio Resource Control (RRC) configuration scheduling information and Downlink Control Information (DCI) activation signaling transmitted from the base station, or acquire the transmission-format configuration parameters of the uplink resources in the DCI activation signaling transmitted from the base station, and then determine, based on the transmission-format configuration parameters of the logical channels and the transmission-format configuration parameters of the uplink resources, the first logical channels among the logical channels the transmission-format configuration parameters of which match the transmission-format configuration parameters of the uplink resources.
Herein the terminal may determine first logical channel among the logical channels a transmission-format configuration parameter of which matches the uplink scheduling information by matching the transmission-format configuration parameter of the logical channels with a transmission-format configuration parameter in the uplink scheduling information. A transmission -format configuration parameter may include SCS and PUSCH-Duration. The logical channel may also have a service transmission mode. The service transmission mode may include a fixed offset of service data, a period of service data, and a packet size of service data. The packet size may be interpreted as the amount of data in which the packet arrives at the terminal in each period or at one time. Accordingly, the uplink scheduling information may include a transmission mode of the uplink resources, and the transmission mode may include a fixed offset, a period, and a packet size. The terminal may determine one or more target logical channels among the first logical channels a service transmission mode of which matches a transmission mode in the uplink scheduling information by matching the transmission mode in the uplink scheduling information with the service transmission mode of the first logical channels, and then determine priorities of the target logical channels as the transmission priorities of the uplink resources.
Optionally, in selecting an uplink resource for data transmission based on the transmission priorities of the uplink resources, the terminal may select, from uplink resources where data to be transmitted exists in the target logical channel, an uplink resource having a highest transmission priority, for data transmission. In a case where a plurality of uplink scheduling information include semi-persistent scheduling information and/or dynamic scheduling information, the terminal may use priorities of target logical channels where data to be transmitted exists as the transmission priorities of the uplink resources corresponding to the target logical channels, and then select, from those uplink resources, an uplink resource having a highest transmission priority, for data transmission.
determining, based on the uplink scheduling information, transmission priority information of the uplink resources in 401; and
determining, based on the transmission priority information, transmission priorities of uplink resources indicated by the uplink scheduling information in 402.
Herein the terminal may acquire transmission priority information in the uplink scheduling information. The transmission priority information may be transmission priority information that is added to the uplink scheduling information transmitted from the base station to the terminal for indicating the uplink resources indicated by the uplink scheduling information. The terminal may determine transmission priorities of the uplink resources based on the transmission priority information. Embodiments of the present disclosure do not limit the number of bits of the transmission priority information. The number of bits of the transmission priority information may be proportional to accuracy at which the transmission priority information is capable of indicating a transmission priority—that is, the higher the accuracy, the more the number of bits of the transmission priority information may be. For example, if the number of indicated transmission priorities is N, then the number of bits of the transmission priority information may be a result of rounding log2N+1. N is a positive integer.
Optionally, in response to the uplink scheduling information being dynamic scheduling information, the terminal may acquire transmission priority information of the uplink resources in Downlink Control Information (DCI) activation signaling transmitted from the base station.
Optionally, in response to the uplink scheduling information being type-1 semi-persistent scheduling information, the terminal may acquire transmission priority information of the uplink resources in Radio Resource Control (RRC) configuration scheduling information transmitted from the base station. In response to the uplink scheduling information being type-2 semi-persistent scheduling information, the terminal may acquire transmission priority information of the uplink resources in Radio Resource Control (RRC) configuration scheduling information transmitted from the base station, or in Downlink Control Information (DCI) activation signaling transmitted from the base station.
acquiring a Radio Network Temporary Identifier (RNTI) with which the uplink scheduling information is scrambled in 501; and
determining, based on the type of the RNTI, the transmission priorities of the uplink resources indicated by the uplink scheduling information in 502.
Herein a RNTI may include a Cell-Radio Network Temporary Identifier (C-RNTI), a Configured Scheduling-Radio Network Temporary Identifier (CS-RNTI), and a Modulation and Coding Scheme-Radio Network Temporary Identifier (MCS-RNTI). Correspondingly, the transmission priorities indicated by the RNTI are arranged in a descending order of MCS-RNTI, CS -RNTI, and C-RNTI. Different types of RNTIs may indicate different levels of reliability of data transmission. An uplink resource having higher reliability may transmit service data having a higher transmission reliability requirement. Thus, the terminal may determine, based on the type of the RNTI, transmission priorities of uplink resources indicated by the uplink scheduling information, and select, for data transmission, an uplink resource having a highest priority.
With the scheme for selecting uplink resources described above, the terminal can select an uplink resource prioritized for data transmission based on transmission priorities of uplink resources. Even when uplink resources corresponding to uplink scheduling information overlap or partially overlap in a time domain, the terminal can still preferentially transmit data having a higher priority to meet a service data transmission demand with higher latency requirements.
Based on the inventive concept same as the uplink resource selection method described above, embodiments of the present disclosure further provide a terminal.
