Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a resource allocation method, a user equipment, and a base station without uplink scheduling grant.
Background
In the case of conventional LTE (long term evolution), uplink and downlink transmissions are based on base station scheduling. Before uplink transmission, User Equipment (UE) needs to send a Scheduling Request (SR) to a base station, and then the base station sends Downlink Control Information (DCI) including an uplink Scheduling (UL grant) to indicate a time-frequency resource, a modulation and coding scheme, a Hybrid Automatic repeat Request (HARQ) timing sequence, and the like of the uplink transmission.
In a New Radio technology (NR), because of a high latency requirement and a small data packet in an Ultra-Reliable and low latency communication (URLLC) service, NR wants to introduce a method of a non-uplink scheduling grant (UL grant free), that is, before uplink transmission, the UE does not need to send an SR to the base station or wait for a resource indication of the UL grant of the base station, but selects a resource for uplink transmission.
If the UE randomly selects resources by itself, it may select resources that have already been allocated to other users, which not only fails its own data transmission, but also affects the data transmission performance of other users served by the base station. To avoid this problem, the 3GPP conference considers that high-layer signaling needs to be introduced to configure the time-frequency resource of the UL grant free. However, if configured by using the RRC dedicated signaling similar to Semi-Persistent scheduling (SPS), the user is required to be in a connected state (connected state), that is, if the user wants to initiate a service in a standby state (idle state), the user needs to enter the connected state first, then receive the RRC dedicated signaling to obtain time-frequency resources, and then perform transmission, which results in an increase of delay.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a resource allocation method for uplink scheduling grant free according to an embodiment of the present invention. The method is used in a 5G NR network system comprising a base station (gNB) and a User Equipment (UE) communicating over a radio link.
As shown in fig. 1, the method comprises the steps of:
step S102, the user equipment obtains resource pool information configured in advance by the base station, wherein the resource pool comprises a plurality of time-frequency domain resources.
The Resource scheduling of the 5G NR system is based on Resource Block (RB), where each RB includes all Orthogonal Frequency Division Multiplexing (OFDM) symbols and subcarriers in one slot or uses a shorter time granularity, such as mini-slot, as a scheduling unit. In this step, the 5G NR base station (gNB) transmits the pre-configured resource pool information (or referred to as time-frequency resource configuration signaling) to the User Equipment (UE) through the System Information (SIB) transmitted by broadcast. Including a plurality of free time and frequency domain resources in the resource pool information, and the resource pool information further includes: modulation and coding mode, uplink sending repetition times, uplink demodulation reference signal parameter configuration, Hybrid Automatic Repeat reQuest (HARQ) timing sequence and the like.
Step S104, before receiving the uplink scheduling permission, the UE selects one or more time-frequency resources from the resource pool to transmit uplink data.
According to the embodiment of the invention, before receiving the uplink scheduling permission, namely before transmitting the first data packet, the UE selects a part of resources from the resource pool for transmitting the first uplink data packet. That is, the UE in the idle state (idle state) already acquires the resource pool information, and immediately after the UE enters the connected state (connected state), the UE can select a resource from the resource pool for uplink transmission. The UE does not need to send a Scheduling Request (SR) to the gNB, and does not need to wait for the resource indication of the UL grant of the gNB, but the UE selects the resource for uplink transmission, so that the time delay can be effectively reduced and the transmission efficiency is improved.
In the embodiment of the present invention, the resource pool information may also be issued through a random access process of the gNB and the UE. According to different service triggering modes, the random access can be divided into contention-based random access and non-contention-based random access, specifically:
contention based random access includes the following four steps (msg1-msg 4):
(1) the user equipment transmitting a random preamble (msg1) to the base station;
(2) the user equipment receives random access feedback information (msg2) sent by the base station;
(3) the user equipment sends competition resolving information (msg3) carrying the user equipment identification to the base station;
(4) and the UE receives contention resolution confirmation information sent by the base station, wherein the contention resolution confirmation information comprises the resource pool information (msg 4).
Non-Contention based random access includes the following two steps (msg1-msg 2):
(1) the user equipment transmitting a random preamble (msg1) to the base station;
(2) and the UE receives random access feedback information sent by the base station, wherein the random access feedback information comprises the resource pool information (msg 2).
In the above embodiment, Msg2 or Msg4 shows a resource pool of time-frequency resources, and the UE selects a part of resources from the resource pool for transmitting its first packet. Therefore, the UE obtains the resource pool information while entering the connected state, namely the UE can select resources from the resource pool for uplink transmission immediately after entering the connected state, so as to reduce the time delay.
According to the above embodiments of the present invention, the delay problem of sending the first data packet is solved by a way of uplink scheduling grant free (UL grant free), and the following method is used for the resource allocation information of the subsequent data packets.
When the UE sends the first data packet, the gNB sends radio resource control indication information (RRCdedicated) to the UE, where the RRCdedicated information is used to indicate semi-persistent scheduling information (SPS) of the URLLC uplink service, and the RRCdedicated information includes, for example: the downlink control information (DCI information) for the UE indicates a cell radio network temporary identity (C-RNTI, hereinafter referred to as a "ULgrantfreeC-RNTI"), a scheduling time resource period, a scheduled process number (processsnumber), and the like to be used.
After the gNB transmits RRC dedicated information to the UE, the gNB transmits DCI information including an uplink scheduling grant (ULgrant) to the UE. The DCI information indicates that the periodical transmission given by RRC dedicated is triggered, and time frequency resources used in each period are given. The subsequent data transmission does not need to transmit DCI information, and the information such as time-frequency resources and the like given by the DCI information can be repeatedly used in each period. Since the resources for periodic transmission all use the resources allocated by the DCI information, the reliability of the DCI information is high, and therefore the DCI information needs to satisfy the following conditions:
(1) scrambling using ULgrantfree C-RNTI;
(2) bits of the special field are set to all 0 or all 1 as an indication identifier of the DCI information.
In an embodiment of the present invention, the time-frequency resource may be released after the user completes transmitting the data packet, or the time-frequency resource may be released after the number of transmission cycles given by the base station is reached, or the base station may further send a DCI message to release the time-frequency resource. It should be noted that, the time-frequency resource allocated by the base station for transmitting the subsequent data packet to the user may be a part of the resource pool, or may not be, and the present invention is not limited thereto.
Fig. 2 is a flowchart of a resource allocation method for uplink scheduling grant free according to another embodiment of the present invention, and the method is used in a 5G NR system. As shown in fig. 2, the method includes:
step S202, a base station configures resource pool information comprising a plurality of time-frequency domain resources;
the Resource scheduling of the 5G NR system is based on Resource Blocks (RBs) each including all OFDM symbols and subcarriers in a slot, or on a shorter time granularity, such as mini-slots. In this step, the base station (gbb) issues the resource pool information (or called time-frequency resource allocation signaling) configured in advance to the User Equipment (UE). Including a plurality of free time and frequency domain resources in the resource pool information, and the resource pool information further includes: modulation and coding mode, uplink transmission repetition times, uplink demodulation reference signal parameter configuration, HARQ time sequence and the like.
Step S204, the base station sends the resource pool information to the user equipment, so that the user equipment selects one or more time-frequency resources from the resource pool to transmit uplink data before receiving the uplink scheduling permission.
In one embodiment, the gbb sends the resource pool information to the UE through System Information (SIB) broadcast, and the UE selects part of resources from the resource pool for transmitting the first uplink data packet before receiving the uplink scheduling grant. That is to say, the UE in idle state has already acquired the resource pool information, and after the UE enters connected state, the UE can select a resource from the resource pool for uplink transmission immediately, and does not need to send an SR to the gNB or wait for a resource indication of an ULgrant of the gNB, thereby effectively reducing the time delay and improving the transmission efficiency.
In the embodiment of the present invention, the resource pool information may also be issued through a random access process of the gNB and the UE. According to different service triggering modes, the random access can be divided into contention-based random access and non-contention-based random access, specifically:
contention based random access includes the following four steps (msg1-msg 4):
(1) the base station receives a random preamble (msg1) transmitted by the user equipment;
(2) the base station transmitting random access feedback information (msg2) to the user equipment;
(3) the base station receives contention resolution information (msg3) which is sent by the user equipment and carries the user equipment identification;
(4) the base station transmits contention resolution acknowledgement information to the user equipment, wherein the contention resolution acknowledgement information includes the resource pool information (msg 4).
Non-Contention based random access includes the following two steps (msg1-msg 2):
(1) the base station receives a random preamble (msg1) transmitted by the user equipment;
(2) the base station sends random access feedback information to the user equipment, wherein the random access feedback information comprises the resource pool information (msg 2).
In the above embodiment, Msg2 or Msg4 shows a resource pool of time-frequency resources, and the UE selects a part of resources from the resource pool for transmitting its first packet. Therefore, the UE obtains the resource pool information while entering the connected state, namely the UE can select the resource from the resource pool for uplink transmission immediately after entering the connected state, and the time delay is reduced.
According to the above embodiments of the present invention, the issue of the transmission delay of the first packet is solved by a manner of uplink scheduling grant free (UL grant free), and the following method is used for the resource allocation information of the subsequent packets.
When the UE sends the first data packet, the gNB sends radio resource control indication information (RRCdedicated) to the UE, where the RRCdedicated information is used to indicate semi-persistent scheduling information (SPS) of the URLLC uplink service, and the RRCdedicated information includes, for example: the DCI information for the UE indicates a cell radio network temporary identifier (C-RNTI, hereinafter referred to as a "ULgrantfree C-RNTI"), a scheduling time resource period, a number of scheduled procedures (process number), and the like to be used.
After the gNB transmits RRC scheduled information to the UE, the gNB transmits Downlink Control Information (DCI) including an uplink scheduling grant (ULgrant) to the UE. The DCI information indicates that the periodical transmission given by RRC dedicated is triggered, and time frequency resources used in each period are given. The subsequent data transmission does not need to transmit DCI information, and the information such as time-frequency resources and the like given by the DCI information can be repeatedly used in each period. Since the resources for periodic transmission all use the resources allocated by the DCI information, the reliability of the DCI information is high, and therefore the DCI information needs to satisfy the following conditions:
(1) scrambling using ULgrantfree C-RNTI;
(2) bits of the special field are set to all 0 or all 1 as an indication identifier of the DCI information.
In an embodiment of the present invention, the time-frequency resource may be released after the user completes transmitting the data packet, or the time-frequency resource may be released after the number of transmission cycles given by the base station is reached, or the base station may further send a DCI message to release the time-frequency resource. It should be noted that, the time-frequency resource allocated by the base station for transmitting the subsequent data packet to the user may be a part of the resource pool, or may not be, and the present invention is not limited thereto.

That is, the UE in the idle state (idle state) selects the resource for uplink data transmission, and immediately after the UE enters the connected state (connected state), the UE can select the resource from the resource pool for uplink transmission. And the UE is not required to send the SR to the gNB, and the UE is not required to wait for the resource indication of the UL grant sent by the gNB, so that the time delay is effectively reduced, and the data transmission efficiency is improved.
In the embodiment of the invention, the resource pool information can be issued through the random access process of the gNB and the UE. According to different service triggering modes, random access can be divided into contention-based random access and non-contention-based random access.
