Description

Carrier determining method and device, user equipment, network equipment and storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a carrier determining method and apparatus, a user equipment, a system information broadcasting method and apparatus, a network device, and a storage medium.
Background
The random access process of the current terrestrial internet of things protocol, such as narrowband internet of things NB-IoT or eMTC, is shown in fig. 1 and comprises four steps of Msg1, Msg2, Msg3 and Msg 4. Msg1, that is, user equipment UE sends a random access preamble to network equipment, the number of repetitions of Msg1 sending is at most 128 at present, and before sending Msg1, the UE obtains current cell Signal quality, for example, RSRP (Reference Signal Receiving Power) through a narrowband Reference Signal NRS, and then compares the measured Signal quality with a relevant threshold configured by the network to determine the current coverage level. Different coverage grades correspond to different PRACH (Physical Random Access Channel) resources (including the number of repetitions of Msg 1), the UE determines the number of repetitions of transmitting Msg1 according to the coverage grade determined by the UE, and randomly determines an uplink carrier transmitting Msg1 configured with the corresponding PRACH resource. If the first Msg1 transmission fails, the UE will upgrade the coverage level (i.e. increase the number of repetitions of Msg 1) and try again until it successfully receives Msg2 or tries the number of repetitions of Msg1 corresponding to the coverage level.
After the network device receives the Msg1, the network device instructs the UE to send Msg3 resources and related parameters (including subcarrier indication, Msg3 repetition number, MCS (Modulation and Coding Scheme) indication, etc.) through a random access response message Msg 2-RAR. The random access response message Msg2-RAR is scheduled by DCI (Downlink Control Information), and the UE first receives Downlink Control Information (i.e. DCI scrambled by RA-RNTI and used for indicating transmission parameters of Msg2-RAR, including a received resource position, a subcarrier indication, Msg3 repetition times, MCS indication, and the like), and then receives Msg2-RAR according to the Downlink Control Information.
And the UE sends the Msg3 according to the relevant scheduling information of the Msg3 indicated by the Msg2-RAR, monitors the PDCCH by using the unique identifier carried in the Msg3 after the UE sends the Msg3, and receives corresponding Msg4 according to the DCI information carried by the PDCCH after the PDCCH is successfully decoded.
In the current internet of things protocol of land networks, a carrier determination mechanism for sending Msg1 is as follows: and the UE randomly determines an uplink carrier for sending the Msg1 from a plurality of uplink carriers configured with PRACH resources and configured in the resident cell. However, in an NTN (Non Terrestrial Networks) scenario, one cell is composed of multiple beams, and different beams correspond to different uplink carrier groups. With the rapid movement of the satellite, the UE needs to perform beam switching frequently, and the existing carrier determination mechanism for sending Msg1 is obviously not adaptable to the satellite internet of things scenario.
In addition, in the existing protocol for determining to receive Paging carriers, the network device issues configuration information about Paging through system information, which includes parameters such as a Paging cycle, PDCCH repetition times corresponding to POs (Paging Occasion), N and Ns (where each DRX cycle includes N Paging frames PF and each PF includes Ns POs), and also configures a Paging weight of each Paging carrier. These parameters are cell level, i.e. the Paging parameter configuration is the same for all carriers within a cell. When the UE is in the Idle state, it can determine which carrier of the camped cell the Paging listening is performed on according to the UE _ ID, the parameter N, the parameter Ns, and the Paging weight of each Paging carrier.
Similarly, in a satellite internet of things scenario, with the rapid movement of the satellite, the UE needs to perform beam switching frequently, and it is obvious that the existing protocol for determining to receive the Paging carrier cannot adapt to the satellite internet of things scenario.

Example 1
Fig. 3 is a flowchart of a carrier determining method provided in this embodiment, where the method may be executed by a carrier determining apparatus, and the apparatus may be implemented by software and/or hardware, and the apparatus may include part or all of user equipment and network equipment. The carrier determination method is described below as an execution subject in conjunction with user equipment and network equipment.
As shown in fig. 3, the carrier determination method provided in this embodiment includes the following steps S101 to S104:
step S101, the network equipment broadcasts system information. The system information includes index configuration information of a downlink carrier wave which is used for transmitting the narrowband reference signal and corresponds to each beam in a cell where the user equipment is located, and index configuration information of a carrier wave which is associated with the downlink carrier wave which is used for transmitting the narrowband reference signal.
In step S101, the network device configures, for each beam in a cell where the user equipment is located, a downlink carrier used for sending a Narrowband Reference Signal (NRS) and a related carrier for the downlink carrier sending the NRS, respectively, and issues index configuration information of the downlink carrier sending the NRS and the related carrier in a manner of broadcasting a system message.
Step S102, the user equipment measures the signal quality of the downlink carrier wave which sends the narrow-band reference signal, and determines the target downlink carrier wave according to the measured signal quality. In a specific implementation, the ue receives system information broadcast by the network device, determines a downlink carrier for transmitting NRS according to the system information, and measures signal quality of the downlink carrier, thereby determining a target downlink carrier.
Wherein the signal quality of the downlink carrier transmitting the NRS may include at least one of: reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Received Signal Strength Indicator (RSSI).
In an optional implementation manner of step S102, the system information broadcast by the network device further includes a reference threshold of signal quality. In this embodiment, step S102 specifically includes: and if the signal quality of the downlink carrier wave for sending the narrowband reference signal is greater than the reference threshold value, taking the downlink carrier wave as a target downlink carrier wave.
In a specific implementation, if there are a plurality of downlink carriers transmitting the narrowband reference signal with signal quality greater than the reference threshold, a downlink carrier with the best signal quality is determined as a target downlink carrier from the plurality of downlink carriers.
In a specific implementation, if there is no downlink carrier for transmitting the narrowband reference signal with a signal quality greater than the reference threshold, the ue does not need to determine the target downlink carrier.
Step S103, the user equipment determines a carrier used for transmitting the target message according to the carrier associated with the target downlink carrier.
And step S104, the user equipment transmits the target message to the network equipment through the determined carrier.
It can be understood that a data transmission bandwidth between the user equipment and the network equipment in the NB-IoT internet of things protocol is one Physical Resource Block (PRB), and one Physical Resource Block is also called one carrier, but a transmission bandwidth between the user equipment and the network equipment in the eMTC internet of things protocol is one narrowband. It should be noted that, if the internet of things protocol is eMTC, the carrier in the embodiment of the present invention is equivalent to a narrowband.
In an optional embodiment, the carriers associated with the downlink carrier for sending the narrowband reference signal are all uplink carriers configured with physical random access channel resources, that is, PRACH resources, and the target message is a random access message. The step S103 specifically includes: and randomly determining an uplink carrier for sending a random access message in the uplink carriers which are associated with the target downlink carrier and are configured with the physical random access channel resources.
In this embodiment, the user equipment may send a random access message to the network device through the uplink carrier randomly determined in step S103 in a random access process, where the random access message may include a random preamble Msg 1. The network equipment configures a plurality of associated uplink carriers for the downlink carrier which is used for sending NRS and corresponds to each wave beam in a cell where the user equipment is located, and configures physical random access channel resources for the uplink carriers, so that the requirement that the user equipment frequently switches the wave beams in a satellite Internet of things scene can be met, specifically, along with the change of the wave beam where the user equipment is located, the user equipment can determine a target downlink carrier according to the signal quality of the downlink carrier which is used for sending the NRS and determine the uplink carrier which is used for sending the random access message in the uplink carrier which is associated with the target downlink carrier, and the stability of satellite communication is improved.
In the example shown in fig. 4, the network device configures one downlink carrier (D11/D12/D13) for transmitting NRS for three beams of the cell where the user equipment is located, and configures two associated uplink carriers for each downlink carrier for transmitting NRS, where the associated uplink carriers have been configured with PRACH resources. Specifically, the downlink carrier D11 associates the uplink carriers U1 and U2, the downlink carrier D12 associates the uplink carriers U3 and U4, and the downlink carrier D13 associates the uplink carriers U5 and U6. The ue measures the signal quality of the downlink carriers D11, D12, and D13, respectively, and compares the measurement result with a reference threshold a, where the reference threshold a is included in the system information broadcast by the network device. The comparison result is: the signal quality of the downlink carrier D11 is greater than a reference threshold A, the signal quality of the downlink carriers D12 and D13 is less than the reference threshold A, the user equipment determines the downlink carrier D11 as a target downlink carrier, and randomly determines one uplink carrier from uplink carriers U1 and U2 associated with the downlink carrier D11, and the uplink carrier is used for sending a random access preamble Msg 1.
In another optional implementation manner, carriers associated with downlink carriers for transmitting narrowband reference signals are downlink paging carriers, the target message is a paging message, and the system information further includes paging weight of the downlink paging carrier associated with the downlink carrier for transmitting narrowband reference signals corresponding to each beam in a cell in which the user equipment is located, and configuration information such as paging parameters corresponding to each beam. The step S103 specifically includes: determining a downlink paging carrier for receiving a paging message in the downlink paging carriers associated with the target downlink carrier according to the identification information of the user equipment, the paging parameter corresponding to the target beam and the paging weight of the downlink paging carrier associated with the target downlink carrier; wherein the target beam is a beam corresponding to the target downlink carrier.
In another optional implementation manner, carriers associated with downlink carriers for sending narrowband reference signals are downlink paging carriers, the target message is a paging message, and the system information further includes a paging weight of the downlink carrier for sending narrowband reference signals corresponding to each beam in a cell where the user equipment is located, a paging weight of the downlink paging carrier associated with the downlink carrier for sending narrowband reference signals, and a paging parameter corresponding to each beam; the step S103 specifically includes: determining a downlink paging carrier for receiving a paging message in the target downlink carrier and the downlink paging carrier associated with the target downlink carrier according to the identification information of the user equipment, the paging parameter corresponding to the target beam, the paging weight of the target downlink carrier and the paging weight of the downlink paging carrier associated with the target downlink carrier; wherein the target beam is a beam corresponding to the target downlink carrier.
It can be understood that the target downlink carrier may also be used for receiving the paging message, and in this embodiment, one carrier for receiving the paging message is determined from the target downlink carrier and its associated downlink paging carrier.
The paging parameters may include the number of paging frames PF in each DRX cycle and the number of paging occasions PO in each paging frame PF.
In a specific example, the identification information of the UE is UE _ ID, and the value is IMSI mod 1024. The IMSI (International Mobile Subscriber Identity) of each Subscriber is unique. The IMSI is represented by a sequence consisting of numbers 0-9 and is stored in the SIM/USIM card. It should be noted that if the user equipment does not have a SIM/USIM card inserted, there is no IMSI, and the UE _ ID is fixed to take 0.
In one example of the specific implementation, the carrier used for receiving the paging message is determined from the target downlink carrier and the downlink paging carrier associated with the target downlink carrier according to the following formula:
(floor(UE_ID/(N*Ns))mod W)<(W(0)+W(1)+…+W(n))；
wherein, floor is a down-rounding function, mod is a remainder function, W (i) is a paging weight of a carrier with a carrier index i in a target downlink carrier and downlink paging carriers related to the target downlink carrier, where i is 0,1,2, … …, N, N is less than or equal to the sum of the number of the target downlink carrier and downlink paging carriers related to the target downlink carrier, W is the sum of the paging weights of the target downlink carrier and all downlink paging carriers related to the target downlink carrier, N and Ns are paging parameters corresponding to a target beam, where the target beam is a beam corresponding to the target downlink carrier, N is the number of paging frames PF in each DRX cycle, and Ns is the number of paging occasions PO in each paging frame PF.
It should be noted that, the carrier indexes are sequentially increased from 0 until the above formula is satisfied for the first time, that is, the left side of the formula is smaller than the right side of the formula, the carrier index X at this time is recorded, and then the carrier with the carrier index X is determined to receive the paging message.
In this embodiment, the network device configures a paging weight and a paging parameter for each beam in a cell in which the user equipment is located, so that a requirement that the user equipment frequently switches beams in a scene of a satellite internet of things can be met, and specifically, as the beam in which the user equipment is located changes, the user equipment can determine a target downlink carrier according to the signal quality of a downlink carrier for transmitting NRS measured in real time, and determine a carrier for receiving a paging message according to the beam corresponding to the target downlink carrier, thereby improving the stability of satellite communication.
In the example shown in fig. 5, the network device configures one downlink carrier (D21/D22/D23) for transmitting NRS for each of three beams of the cell where the user equipment is located, and configures two associated downlink paging carriers for each downlink carrier for transmitting NRS. Specifically, downlink carrier D21 is associated with downlink paging carriers D1 and D2, downlink carrier D22 is associated with downlink paging carriers D3 and D4, and downlink carrier D23 is associated with downlink paging carriers D5 and D6. The ue measures the signal quality of the downlink carriers D21, D22, and D23, respectively, and compares the measurement result with a reference threshold B, where the reference threshold B is included in the system information broadcast by the network device. The comparison result is: the signal quality of the downlink carrier D22 is less than the reference threshold B, the signal qualities of the downlink carriers D21 and D23 are both greater than the reference threshold B, and the signal quality of the downlink carrier D21 is greater than the signal quality of the downlink carrier D23, the user equipment determines the downlink carrier D21 with the best signal quality as a target downlink carrier, and determines one carrier from the downlink carrier D21 and the associated downlink paging carriers D1 and D2 for receiving a paging message. Specifically, the carrier for receiving the paging message is determined according to the identification information UE _ ID of the user equipment, the paging weight of the downlink carrier D21, the paging weights of the downlink paging carriers D1 and D2, and the paging parameter configured for the target beam by the network equipment. The target beam in this example is a beam corresponding to downlink carrier D21.
