The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The terms "first," "second," and the like in this application are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in this application means at least one of the connected objects, such as a and/or B and/or C, is meant to encompass the 7 cases of a alone, B alone, C alone, and both a and B, both B and C, both a and C, and both A, B and C.
For ease of understanding, some of the following descriptions are directed to embodiments of the present invention:
1. configured uplink Grant (CG).
In the fifth generation (5 th Generation, 5G) mobile communication system, the network side configures a periodic uplink resource for UE data transmission, where the periodic uplink resource may be referred to as CG. The transmission channel of the periodic uplink resource is a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH). The periodic uplink resources can be divided into the following 2 types:
uplink configuration grant type 1 (UL configured grant Type 1): the resource allocation period and the resource specific allocation information of each period are configured through radio resource control (Radio Resource Control, RRC) signaling;
uplink configuration grant type 2 (UL configured grant Type 2): the resource allocation period is configured through the RRC signaling, and then the network side designates the specific resource allocation information of each period through the downlink control information (Downlink Control Information, DCI).
The specific resource allocation information of each period may include: the location and number of physical resource blocks (Physical Resource Block, PRBs); modulation coding scheme (Modulation and Coding Scheme, MCS).
When a terminal (also referred to as a User Equipment (UE)) is in an Uplink Non-synchronized state (Uplink Non-synchronized), the UE cannot transmit an Uplink signal, and thus cannot use CG. If the UE arrives at this time, the UE needs to trigger a random access procedure, and after acquiring a Timing Advance (TA) of an uplink signal through the random access procedure, the UE can send the uplink signal in an uplink synchronization state and use CG.
2. Random access procedure.
The random access procedure may be triggered by the following events:
initial access in RRC IDLE state (IDLE);
RRC connection reestablishment procedure;
downlink or uplink data of the RRC connection state arrives, and the uplink synchronization state is out-of-synchronization;
the physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources, which have arrived and are not configured by RRC-connected uplink data, are used as scheduling requests (Scheduling Request, SR);
SR transmission fails;
synchronous reconfiguration (e.g., handover) of RRC requests;
state transitions (e.g., transitions to RRC connected state) of RRC INACTIVE state (INACTIVE);
establishing uplink timing of a Secondary Cell (SCell);
requesting system information;
beam failure recovery.
3. Two Step random access procedure (2-Step RACH).
As shown in fig. 1, the two-step random access procedure may include the steps of:
The configuration information of the two-step random access may include: and sending resource information corresponding to the messages (Message, msg) A and MsgB.
The UE triggers a 2-step RACH procedure and sends request information (MsgA) to the network side, e.g. MsgA via PUSCH. Meanwhile, the UE may also send PRACH information to the network side device.
As shown in fig. 1, the MsgA may carry Data (Data) and a UE identification (UE-ID).
After transmitting the MsgA, the UE listens for reception of the MsgB for a period of time, i.e. a random access response (Random Access Response, RAR) Window (Window).
If the UE fails to receive the MsgB, the UE resends the MsgA.
In case of successful random access, as shown in fig. 1, the UE-ID and the positive acknowledgement Indication (ACK Indication) may be carried in the MsgB.
For a two-step random access procedure, the UE may send a physical random access channel (Physical Random Access Channel, PRACH) and a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) in Msg a in an out-of-sync state. If one MsgA transmission is unsuccessful, the UE may retransmit the MsgA with increased transmission power of the MsgA.
The resource using method according to the embodiment of the present invention is described below.
Referring to fig. 2, fig. 2 is a flowchart of a resource usage method according to an embodiment of the present invention. The resource using method of the embodiment of the invention is applied to the communication equipment. In particular, the communication device may be a terminal or a network-side device. In practical applications, the terminal may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (webable Device), or a vehicle-mounted Device. The network side device may be a base station, a relay or an access point.
As shown in fig. 2, the resource usage method may include the steps of:
It should be understood that, in the case where the communication device is a terminal, the transmitting data using the uplink transmission resource in the target process may be specifically expressed as: and transmitting data by using the uplink transmission resource in the target process. In the case that the communication device is a network side device, the transmitting data using the uplink transmission resource in the target process may be specifically expressed as: and receiving data by using the uplink transmission resource in the target process.
In particular, the periodic uplink transmission resource can be used in a random access process and an uplink data transmission process, and can be configured or agreed by the network side equipment. That is, the application range of the periodic uplink transmission resource may be agreed by the network side device or the protocol.
In this embodiment, for the random access procedure, the terminal can only use one uplink transmission resource of the periodic uplink transmission resources to transmit data in one random access procedure. The random access procedure of the present embodiment may be specifically expressed as a two-step random access procedure.
For the uplink data transmission process, the terminal may continuously transmit data using the periodic uplink transmission resource. Therefore, the uplink data transmission procedure of the present embodiment may also be referred to as a continuous uplink data transmission procedure.
For ease of understanding, the following is illustrated in connection with fig. 3:
in fig. 3, uplink transmission resources including 3 periods are respectively in the following order according to time: uplink transmission resource 1, uplink transmission resource 2, and uplink transmission resource 3.
For the uplink data transmission process, the terminal may continuously transmit data using the uplink transmission resource 1, the uplink transmission resource 2, and the uplink transmission resource 3.
For the random access procedure, after the terminal transmits the MsgA using the uplink transmission resource 1, it needs to monitor for a period of time for receiving the MsgB. The terminal cannot use the periodic uplink transmission resource during the reception time of the listening MsgB. If the usage time of the uplink transmission resource 2 in fig. 3 is within the reception time of the listening MsB, the terminal cannot use the uplink transmission resource 2.
In this embodiment, optionally, the uplink transmission resource may include a first channel resource and a second channel resource.
In a specific implementation, the first channel may be a control channel, and the second channel may be a data channel, that is, the uplink transmission resource may include a control channel resource and a data channel resource.
Further, the control channel may be PRACH and the data channel may be PUSCH. In this case, each uplink transmission resource may include 1 PRACH resource and 1 PUSCH resource, and the terminal needs to simultaneously transmit PUSCH and PRACH when transmitting data.
For ease of understanding, please refer to fig. 4. In fig. 4, uplink transmission resources 1 include PRACH resources 1 and PUSCH resources 1; the uplink transmission resource 2 comprises a PRACH resource 2 and a PUSCH resource 2; the uplink transmission resource 3 includes PRACH resource 3 and PUSCH resource 3.
The resource usage method of the present embodiment may be used for a random access procedure, and the periodic uplink transmission resource may be used for an uplink data transmission procedure, and the communication device may select to transmit data using the uplink transmission resource in a target procedure, where the target procedure includes at least one of the random access procedure and the uplink data transmission procedure. In this way, the embodiment of the invention not only expands the application range of the periodic uplink transmission resource, but also reasonably selects the random access process and the uplink data transmission process, so that the uplink transmission resource is used for transmitting data in the target process, and the reliability of the resource use can be improved.
In this embodiment, the target rule may be determined by the terminal and the network side device according to the target rule. Optionally, the target rule is configured by the network side device or agreed by a protocol.
And in the case that the target rule is configured by the network side equipment, the target rule is determined by the network side equipment and configured to the terminal. In specific implementation, the network side device may send configuration information, where the configuration information is used to configure the target rule.
In the case that the target rule is predetermined by the protocol, in order to ensure that the target processes determined by the terminal and the network side device are the same, the terminal and the network side device need to determine the target processes through the same rule.
Optionally, before the target process uses the uplink transmission resource to transmit data, the method further includes:
determining the target process according to a target rule;
wherein the target rule includes any one of the following:
a first rule for: determining the target process according to the size of the uplink data to be transmitted and the size of the uplink data which can be transmitted by the uplink transmission resource;
a second rule for: determining the target process according to the trigger event of the random access process;
a third rule for: and determining the random access procedure and the uplink data transmission procedure as the target procedure.
The concrete explanation is as follows:
in case one, the target rule includes the first rule.
Optionally, the determining the target process according to a target rule includes at least one of:
determining the uplink data transmission process as the target process under the condition that the size of uplink data to be transmitted is larger than the size of uplink data which can be transmitted by the uplink transmission resource;
and determining the random access process as the target process under the condition that the size of the uplink data to be transmitted is smaller than or equal to the size of the uplink data which can be transmitted by the uplink transmission resource.
And under the condition that the size of the uplink data to be transmitted is larger than the size of the uplink data which can be transmitted by the uplink transmission resource, the fact that the transmission of the uplink data to be transmitted cannot be completed through 1 uplink transmission resource is indicated, namely the uplink data to be transmitted needs to be transmitted through at least two uplink transmission resources. Therefore, the periodic uplink transmission resource can be used for transmitting the uplink data to be transmitted in the uplink data transmission process, so that the transmission time delay of the uplink data to be transmitted can be shortened.
When the size of the uplink data to be sent is smaller than or equal to the size of the uplink data which can be sent by the uplink sending resource, the fact that the uplink data to be sent can be sent through 1 uplink sending resource is indicated, namely, the uplink data to be sent can be transmitted through only 1 uplink sending resource. Therefore, the periodic uplink transmission resource can be used for transmitting the uplink data to be transmitted in the random access process, so that the transmission of the uplink data to be transmitted can be completed in the random access process, and the power consumption of the communication equipment is reduced.
In a scenario that each uplink transmission resource includes 1 PUSCH resource and 1 PRACH resource, the size of the uplink data that can be transmitted by the uplink transmission resource may be specifically expressed as: 1 PUSCH resource may transmit the size of uplink data.
Illustratively, assume that the transport block size (Transport Block Size, TBS) of the Uplink Grant (Uplink Grant) of PUSCH resources is 40 bits (bits).
If the size of the media access control (Medium Access Control, MAC) protocol data unit (Protocol Data Unit, PDU) corresponding to the data to be transmitted is 80 bits, the communication device may select the uplink data transmission procedure as the target procedure.
If the size of the MAC PDU corresponding to the data to be transmitted is 20 bits, the communication device may select the random access procedure as the target procedure.
In case two, the target rule includes the second rule.
Optionally, the determining the target process according to the target rule includes:
and in the case that the triggering event of the random access procedure comprises beam failure recovery, determining the random access procedure as the target procedure.
In this embodiment, in the case where the trigger event of the random access procedure includes beam failure recovery, the terminal preferentially performs beam failure recovery, and thus, determines the random access procedure as the target procedure.
Illustratively, a beam failure occurs in a Primary Cell (PCell), a Primary Cell (Primary Secondary Cell, PSCell) of a secondary Cell group, or SCell of the terminal, and the terminal triggers a random access procedure for beam failure recovery. Assuming that the TBS of Uplink Grant of PUSCH resource is 40 bits and the size of MAC PDU corresponding to data to be sent by the terminal is 80 bits, the terminal preferentially triggers the random access process for beam failure recovery, thereby selecting the random access process as the target process.
In case three, the target rule includes the third rule.
Optionally, the determining the target process according to the target rule includes:
and determining the random access procedure and the uplink data transmission procedure as the target procedure.
In this embodiment, the terminal may transmit data using the periodic uplink transmission resource in the random access procedure and the uplink data transmission procedure. Therefore, after triggering the random access procedure, if there is data to be transmitted, the terminal can transmit in the uplink data transmission procedure.
Please refer to fig. 3 again. It is assumed that the UE triggers a random access procedure and transmits MsgA using uplink transmission resources in the random access procedure. After the MsgA is sent, the UE has uplink data to send, and the uplink transmission resource 2 is within the reception time window of the MsgB. At this time, the UE may continue to transmit uplink data using the uplink transmission resource 2 in the uplink data transmission process.
In this way, compared with the uplink data transmission process or the random access process, the present embodiment can improve the utilization rate of the resource usage, thereby improving the reliability of the resource usage.
And in the fourth case, the target rule comprises the fourth rule.
Optionally, the determining the target process according to a target rule includes at least one of:
determining the uplink data transmission process as the target process under the condition that the priority of the uplink data to be transmitted is greater than or equal to a first threshold value;
and determining the random access process as the target process under the condition that the priority of the uplink data to be sent is smaller than the first threshold value.
In particular implementation, the first threshold value may be configured by the network side device or agreed upon by a protocol.
In this embodiment, when the priority of the uplink data to be transmitted is high, the uplink data transmission process is used to transmit the data, so that the transmission delay of the uplink data to be transmitted can be reduced.
And under the condition that the priority of the uplink data to be sent is lower, adopting a random access process to transmit the data, so that the transmission of the uplink data to be sent can be completed in the random access process, and the power consumption of the communication equipment can be reduced.
In specific implementation, the priority of the uplink data to be sent may be determined by at least one of the following manners:
determining the priority of the uplink data to be sent according to the priority of the logic channel of the uplink data to be sent;
determining the priority of the uplink data to be sent according to the type of the channel for transmitting the uplink data to be sent;
and determining the priority of the uplink data to be sent according to the priority of a Control Element (CE) of a media access Control (Medium Access Control, MAC) Control unit for transmitting the uplink data to be sent.
For mode one, the priority of the uplink data to be transmitted is positively correlated with the priority of the logical channel of the uplink data to be transmitted. That is, the higher the priority of the logical channel of the uplink data to be transmitted, the higher the priority of the uplink data to be transmitted.
For mode two, the channel types may include control channels and data channels. Further, the priority of the uplink data to be transmitted, which is transmitted through the control channel, is higher than the priority of the uplink data to be transmitted, which is transmitted through the data channel. Illustratively, data from the signaling radio bearer (Signaling Radio Bearer, SRB) has a higher data priority than the data radio bearer (Data Radio Bearer, DRB).
For mode three, the MAC CEs may include buffer status report (Buffer Status Report, BSR) MAC CEs, power headroom report (Power Headroom Report, PHR) MAC CEs, dedicated data channel (Dedicated Traffic Channel, DTCH) MAC CEs, and the like. Further, the data priority of the BSR/PHR MAC CE is higher than the data priority of the DTCH).
In case five, the target rule includes the fifth rule.
Optionally, the determining the target process according to a target rule includes at least one of:
determining the uplink data sending process as the target process under the condition that the delay requirement of the uplink data to be sent is greater than or equal to a second threshold value;
and determining the random access process as the target process under the condition that the delay requirement of the uplink data to be sent is smaller than the second threshold value.
In particular implementations, the second threshold may be configured by the network side device or agreed upon by the protocol.
In this embodiment, when the delay requirement of the uplink data to be sent is high, the uplink data sending process is adopted to transmit the data, so that the sending delay of the uplink data to be sent can be reduced.
Under the condition that the time delay requirement of the uplink data to be sent is low, the data is transmitted by adopting a random access process, so that the random access can be realized under the condition that the time delay requirement of the uplink data to be sent is met, and the power consumption of the communication equipment can be reduced.
In particular, the higher the delay requirement, the smaller the corresponding time value of the delay requirement. For ease of understanding, examples are illustrated below:
assuming that the delay requirement for the upstream data to be transmitted is 1 millisecond (ms), the second threshold is 2ms. It can be seen that the delay requirement of the uplink data to be transmitted is higher than the second threshold value, so that the uplink data transmission process can be used to transmit the data.
In other implementations of this embodiment, the target rule may be determined by the network device and then indicated to the terminal. In this way, the operational burden on the terminal may be reduced compared to embodiments in which the target rule is determined by the terminal according to the target rule.
The resource usage method of the present embodiment may be applicable to a terminal uplink out-of-step scenario, but is not limited thereto.
It should be noted that, the various alternative embodiments described in the embodiments of the present invention may be implemented in combination with each other, or may be implemented separately, which is not limited to the embodiments of the present invention.
For ease of understanding, examples are illustrated below:
the resource usage method may include the steps of:
step one, network side equipment configures the position of periodic uplink transmission resources, wherein each uplink transmission resource simultaneously comprises control channel resources and data channel resources.
For example, the period of the uplink transmission resource configured by the network side device is 1 millisecond (ms), and each uplink transmission resource includes 1 PRACH resource and 1 PUSCH resource, so that when the UE transmits uplink data, PUSCH and PRACH need to be transmitted simultaneously.
Further, the network side device configures or agrees with the protocol, and the uplink transmission resource can be used for both the "random access procedure" and the "continuous uplink transmission procedure".
As shown in fig. 4, for the "persistent uplink data transmission procedure", the UE may continuously use (prach1+pusch 1) and (prach2+pusch 2).
For the "random access procedure", the UE needs to listen for a period of time for receiving the MsgB after transmitting the MsgA using (prach1+pusch 1). The UE cannot use the periodic uplink transmission resource during the reception time of the listening MsgB. As shown above (prach2+pusch 2), the UE cannot use (prach2+pusch 2) during the reception time of the listening MsgB.
And step two, for the periodic uplink transmission resource, the network side equipment configures or agrees with rules of the UE selecting a random access process and a continuous uplink data transmission process so that the UE selects a target process according to the rules and uses the periodic uplink transmission resource to transmit data in the target process.
Wherein the rule may include any one of:
rule 1: when the size of uplink data to be transmitted by the UE is larger than the uplink data size that can be transmitted by 1 PUSCH resource, the UE selects a "persistent uplink data transmission procedure".
For example, the TBS of the Uplink Grant of the PUSCH resource is 40 bits, and the size of the MAC PDU corresponding to the data to be transmitted by the UE is 80, and the UE selects a "continuous Uplink data transmission procedure".
Rule 2: when the size of uplink data to be transmitted by the UE is smaller than or equal to the uplink data size that can be transmitted by 1 PUSCH resource, the UE selects a "random access procedure".
Rule 3: when the UE triggers a random access procedure for beam failure recovery, a "random access procedure" is preferentially employed.
For example, the TBS of Uplink Grant of PUSCH resources is 40 bits. The PCell/PSCell/SCell of the UE has beam failure, and the UE triggers a random access procedure for beam failure recovery. Meanwhile, if the size of the MAC PDU corresponding to the data to be sent by the UE is 80, the UE preferentially triggers the random access process.
Rule 4: the UE may use the periodic resources using both a "random access procedure" and a "persistent uplink data transmission procedure".
As shown in fig. 4, the UE triggers the random access procedure to transmit MsgA using (prach1+pusch 1). After the transmission of the MsgA, the UE has further uplink data transmission, and (prach2+pusch 2) is within the reception time window of the MsgB. At this time, the UE may continue to transmit uplink data using (prach2+pusch 2).
By adopting the resource using method of the embodiment of the invention, when the network side equipment configures the periodic PRACH+PUSCH resource to be used for the continuous uplink data transmission process and the random access process at the same time, the UE can reasonably select between the continuous uplink data transmission process and the random access process through the rules agreed by the network configuration or the protocol, such as reducing the data transmission delay through continuous data transmission or recovering the beam failure through initiating the random access process.
Referring to fig. 5, fig. 5 is one of the block diagrams of the communication device according to the embodiment of the present invention. As shown in fig. 5, the communication device 500 includes:
a transmission module 501, configured to transmit data using the uplink transmission resource in a target procedure when a periodic uplink transmission resource is available for a random access procedure and an uplink data transmission procedure;
wherein the target procedure includes at least one of the random access procedure and the uplink data transmission procedure.
Optionally, the communication device 500 further includes:
the first determining module is used for determining the target process according to a target rule before the target process uses the uplink transmission resource to transmit data;
wherein the target rule includes any one of the following:
a first rule for: determining the target process according to the size of the uplink data to be transmitted and the size of the uplink data which can be transmitted by the uplink transmission resource;
a second rule for: determining the target process according to the trigger event of the random access process;
a third rule for: determining the random access procedure and the uplink data transmission procedure as the target procedure;
a fourth rule for: determining the target process according to the priority of the uplink data to be sent;
a fifth rule for: and determining the target process according to the delay requirement of the uplink data to be sent.
Optionally, in the case that the target rule includes the first rule, the first determining module is specifically configured to at least one of:
determining the uplink data transmission process as the target process under the condition that the size of uplink data to be transmitted is larger than the size of uplink data which can be transmitted by the uplink transmission resource;
and determining the random access process as the target process under the condition that the size of the uplink data to be transmitted is smaller than or equal to the size of the uplink data which can be transmitted by the uplink transmission resource.
Optionally, in the case that the target rule includes the second rule, the first determining module is specifically configured to:
and in the case that the triggering event of the random access procedure comprises beam failure recovery, determining the random access procedure as the target procedure.
