Description

[Technical Field]

[0001] This invention relates to the field of wireless communication technology, and in particular to a lightweight user equipment type identification method, apparatus, base station, and user equipment. [Background Technology]

[0002] In the 3rd Generation Partnership Project (3GPP), when reduced-capability UEs and non-reduced-capability UEs access the same cell network, the base station (gNodeB, gNB) can identify whether a UE is a reduced-capability or non-reduced-capability UE through Msg1, Msg3, Msg5, or UE capability reporting. One feasible approach to identifying reduced-capability and non-reduced-capability UEs through Msg1 is to use different Random Access Occasion (RO) resources for them. Non-reduced-capability UEs include enhanced mobile broadband (eMBB) and ultra-reliable low-latency communications (URLLC) UEs.

[0003] Currently, 3GPP is also discussing whether to define one type or two types of lightweight user equipment. If two types of lightweight user equipment are defined, the gNB may need to identify which type of lightweight user equipment a lightweight user equipment is during the initial access phase, because the capabilities of the two types of lightweight user equipment are different. For example, one type of lightweight user equipment is a downlink single antenna, while the other type of lightweight user equipment is a downlink two antenna.

[0004] However, there is currently no method in the relevant technologies that can identify the type of lightweight user equipment. [Summary of the Invention]

Detailed Implementation Methods

[0066] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0067] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0068] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0069] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0070] In related technologies, according to the current 3GPP protocol, the gNB configures the time-domain resources of the Remote Access Module (RO) through the Physical Random Access Channel (PRACH) configuration index prach-ConfigurationIndex, and configures the frequency-domain resources of the RO through msg1-FDM and msg1-FrequencyStart. These three parameters—prach-ConfigurationIndex, msg1-FDM, and msg1-FrequencyStart—together determine the time-frequency resources of the RO. Therefore, the most direct method to identify different UE types based on different RO resources is to allocate different RO resources to different UE types, that is, to allocate different RO resources to different UE types by configuring different prach-ConfigurationIndex or msg1-FDM & msg1-FrequencyStart parameters.

[0071] UE types include non-lightweight user equipment and two types of lightweight user equipment, namely, Type I lightweight user equipment and Type II lightweight user equipment. For example... Figure 1 As shown, one RO resource is allocated to each of the non-lightweight user equipment, type 1 lightweight user equipment, and type 2 lightweight user equipment. Since allocating different RO resources to different types of UEs introduces significant signaling overhead, some companies at the 3GPP meeting opposed using Msg1 to identify different UE types.

[0072] Therefore, identifying the type of lightweight user equipment has become an urgent technical problem to be solved.

[0073] To address the aforementioned technical problems, embodiments of the present invention provide a lightweight user equipment type identification method, apparatus, base station, and user equipment. Figure 2 A flowchart illustrating a lightweight user equipment type identification method according to an embodiment of the present invention, applied to a base station, such as... Figure 2 As shown, the method includes:

[0074] Step 101: Broadcast the RACH configuration information of lightweight user equipment in the cell via a broadcast message. The RACH configuration information includes the proportion parameters of RO resources that can be used by different types of lightweight user equipment, so that the lightweight user equipment can send Msg1 to the base station using the RO resources corresponding to the type of lightweight user equipment according to the proportion parameters and the type of lightweight user equipment.

[0075] In this embodiment of the invention, each step is performed by the base station (gNB).

[0076] Specifically, in this step, the gNB broadcasts the Random Access Channel (RACH) configuration information of the lightweight user equipment in the cell via System Information Broadcast (SIB).

[0077] As can be seen from the above, the RACH configuration information includes prach-ConfigurationIndex, msg1-FDM, msg1-FrequencyStart, Synchronization Signal Block (SSB) number, ssb-perRACH-Occasion, and scaling parameters.

[0078] The prach-ConfigurationIndex determines the length of each RO period and the number of ROs in the time domain, with NT representing the number of ROs in the time domain for each RO period.

[0079] The msg1-FDM and prach-ConfigurationIndex together determine the total number of ROs in each PRACH period. The total number of ROs in each PRACH period is: msg1-FDM * NT.

[0080] The SSB number and ssb-perRACH-Occasion together determine the number of ROs required to map all SSBs in one round, i.e., SSB number / ssb-perRACH-Occasion. For example, if SSB number = 4 and ssb-perRACH-Occasion = 1 / 2, at least 8 ROs are needed to map all SSBs in one round. Here, ssb-perRACH-Occasion represents the number of SSBs corresponding to each RO.

[0081] If SSB number / ssb-perRACH-Occasion > msg1-FDM*NT, then the association period contains multiple PRACH periods. For one SSB, one association period corresponds to 1 / ssb-perRACH-Occasion of ROs. For example... Figure 3 As shown, an association period contains two PRACH periods, and SSB1 corresponds to the two ROs, RO1 and RO2.

[0082] If SSB number / ssb-perRACH-Occasion <= msg1-FDM*NT, then one PRACH period is one association period, such as Figure 4 Example in the middle circle.

[0083] In this embodiment of the invention, the lightweight user equipment types include: a first type of lightweight user equipment and a second type of lightweight user equipment.

[0084] like Figure 5As shown in the figure, the gNB allocates a piece of RO resource to a non-lightweight user equipment and a piece of RO resource to two types of lightweight user equipments, and introduces a proportional parameter to indicate the ratio of the RO resources that the first type of lightweight user equipment and the second type of lightweight user equipment can use, which can save the signaling overhead. Among them, the ratio of the RO resources used by the first type of lightweight user equipment is the proportional parameter divided by the number of RO resources corresponding to each SSB; the ratio of the RO resources used by the second type of lightweight user equipment is 1 minus the ratio of the RO resources occupied by the first type of lightweight user equipment.

[0085] For example, the proportional parameter is M, and the number of RO resources corresponding to each SSB in an association period is Q, then the number of RO resources corresponding to each SSB in K association periods is KQ. Among them, (K - 1)Q < M < K*Q, and K and Q are natural numbers. Therefore, the ratio of the RO resources used by the first type of lightweight user equipment is the proportional parameter M divided by the number of RO resources corresponding to each Synchronization Signal Block (SSB), that is, M / KQ; the ratio of the RO resources used by the second type of lightweight user equipment is 1 minus the ratio of the RO resources occupied by the first type of lightweight user equipment M / KQ, that is, (KQ - M) / KQ. Among them, M ≠ nQ, where n is a positive integer. To round up M / Q, that is, if M / Q is an integer, then K = M / Q; otherwise, K is equal to the integer part of M / Q plus 1.

[0086] It should be noted that regardless of which configuration, each SSB corresponds to several ROs in an association period. Assume that each SSB corresponds to Q ROs in an association period. The ROs that different types of lightweight user equipments can use are numbered in the order of frequency domain first and then time domain for the KQ ROs corresponding to each SSB in K association periods. Then the mapping methods include two types:

[0087] The first mapping method is continuous mapping. Taking K association periods as a unit, the first type of lightweight user equipment uses the first M ROs corresponding to each SSB; the second type of lightweight user equipment uses the (M + 1)th to KQth ROs corresponding to each SSB.

[0088] The second mapping method is a discontinuous mapping, using K association periods as units. SSBx#y represents the y-th RO corresponding to the x-th SSB, where y is the index of the RO corresponding to SSBx, y = 0, 1, ..., K*Q-1. The numbers of y are assigned first in the frequency domain and then in the time domain. When M <= Q / 2, the index of the RO corresponding to each SSBx used by the first type of lightweight user equipment satisfies y mod k = 0, where... To round down Q / M, that is, if Q / M is an integer, kQ / M; otherwise, k equals the integer part of Q / M plus 1. When M>Q / 2, the index of the RO corresponding to each SSBx used by the second type of lightweight user equipment satisfies y mod k=0, where To round up K*Q / (K*QM), that is, if K*Q / (K*QM) is an integer, k = K*Q / (K*QM); otherwise, k equals the integer part of K*Q / (K*QM) plus 1.

[0089] For the second mapping method mentioned above, for example: Figure 6 As shown, Q=4, and when M=5, K=2. The second type of lightweight user equipment uses SSB1-4#0, SSB1-4#3, SSB1-4#6 and SSB5-8#0, SSB5-8#3, SSB5-8#6; the first type of lightweight user equipment uses SSB1-4#1, SSB1-4#2, SSB1-4#4, SSB1-4#5, SSB1-4#7 and SSB5-8#1, SSB5-8#2, SSB5-8#4, SSB5-8#5, SSB5-8#7.

[0090] Step 102: Identify the lightweight user equipment type based on the RO resources used by the lightweight user equipment to send Msg1.

[0091] In a technical solution for identifying lightweight user equipment (User Equipment) types provided by this invention, RACH configuration information of lightweight User Equipment within a cell is broadcast via a broadcast message. The RACH configuration information includes a proportion parameter of RO resources available for different lightweight User Equipment types. This allows the lightweight User Equipment to send Msg1 to the base station using RO resources corresponding to its type, based on the proportion parameter and its specific lightweight User Equipment type. The base station then identifies the lightweight User Equipment type based on the RO resources used by the lightweight User Equipment to send Msg1. This invention introduces a proportion parameter to determine the RO resources available for different types of lightweight User Equipment and identifies the lightweight User Equipment type based on the RO resources used.

[0092] Figure 7 This is a flowchart illustrating a lightweight user equipment type identification method according to another embodiment of the present invention, which is applied to lightweight user equipment. Figure 7 As shown, the method includes:

[0093] Step 201: According to the RACH configuration information of the lightweight user equipment in the cell broadcast by the base station, the RACH configuration information includes the proportion parameters of RO resources that can be used for different lightweight user equipment types. The RO resources corresponding to the lightweight user equipment type are used to send Msg1 to the base station so that the base station can identify the lightweight user equipment type of the lightweight user equipment based on the RO resources used by the lightweight user equipment to send Msg1.

[0094] In this embodiment of the invention, the lightweight user equipment types include: a first type of lightweight user equipment and a second type of lightweight user equipment.

[0095] In this embodiment of the invention, the proportion of RO resources used by the first type of lightweight user equipment is the proportion parameter divided by the number of RO resources corresponding to each SSB; the proportion of RO resources used by the second type of lightweight user equipment is 1 minus the proportion of RO resources occupied by the first type of lightweight user equipment.

[0096] In a technical solution for identifying lightweight user equipment (User Equipment) types provided by this invention, the RACH configuration information of lightweight User Equipment (User Equipment) within a cell is broadcast by the base station. The RACH configuration information includes a proportional parameter of the available RO resources for different lightweight User Equipment types. The RO resources corresponding to the lightweight User Equipment type are used to send Msg1 to the base station, so that the base station can identify the lightweight User Equipment type based on the RO resources used by the lightweight User Equipment in sending Msg1. This invention introduces a proportional parameter to determine the available RO resources for different types of lightweight User Equipment and identifies the lightweight User Equipment type based on the RO resources used by the lightweight User Equipment.

[0097] Figure 8 This is a schematic diagram of a lightweight user equipment type identification device according to an embodiment of the present invention. The device is located in a base station, such as... Figure 8 As shown, the device includes: a broadcast module 31 and an identification module 32.

[0098] The broadcast module 31 is used to broadcast the RACH configuration information of lightweight user equipment in the cell through broadcast messages. The RACH configuration information includes the proportion parameters of RO resources that can be used by different types of lightweight user equipment, so that the lightweight user equipment can send Msg1 to the base station using the RO resources corresponding to the type of lightweight user equipment according to the proportion parameters and the type of lightweight user equipment.

[0099] In this embodiment of the invention, the lightweight user equipment types include: a first type of lightweight user equipment and a second type of lightweight user equipment.

[0100] In this embodiment of the invention, the proportion of RO resources used by the first type of lightweight user equipment is the proportion parameter divided by the number of RO resources corresponding to each SSB; the proportion of RO resources used by the second type of lightweight user equipment is 1 minus the proportion of RO resources occupied by the first type of lightweight user equipment.

[0101] The identification module 32 is used to identify the lightweight user equipment type of the lightweight user equipment based on the RO resources used by the lightweight user equipment sending Msg1.

[0103] The lightweight user equipment type identification device may be, for example, a chip, a chip module, or a part of a chip module.

[0104] In a technical solution provided by this invention, a lightweight user equipment type identification device broadcasts RACH configuration information of lightweight user equipment within a cell via a broadcast message. The RACH configuration information includes a proportion parameter of available RO resources for different lightweight user equipment types. This allows the lightweight user equipment to send Msg1 to the base station using RO resources corresponding to its type, based on the proportion parameter and its own type. The base station then identifies the lightweight user equipment type based on the RO resources used by the lightweight user equipment to send Msg1. This invention introduces a proportion parameter to determine the available RO resources for different types of lightweight user equipment and identifies the lightweight user equipment type based on the RO resources used.
