Abstract
Description
[0001] This application is a divisional application of the PCT international patent application PCT / CN2021 / 093173 with an application date of May 11, 2021, which entered the Chinese national phase with Chinese patent application number 202180091930.0 and the invention name being "Information Indication Method, Terminal Device, Network Device, Chip and Storage Medium". Background Art

It also supports other types of services that have different requirements in terms of speed, bandwidth, power consumption, cost, etc., such as sensor networks, video surveillance, wearable devices, etc. The capabilities of terminals supporting these services are reduced compared to those supporting eMBB, such as reduced supported bandwidth, relaxed processing time, reduced number of antennas, and relaxed maximum modulation order. Such terminals can be called reduced capability (RedCap) terminals.
[0004] In order to facilitate network equipment to set the transmission mode of the downlink channel according to different terminal types, in the related technology, the RedCap terminal is allowed to report its terminal type or capability during the random access process, so that the network equipment can identify the access of the RedCap terminal earlier and optimize the transmission capability of the RedCap to improve the transmission efficiency. This reporting method can be called early indication. However, when the terminal makes an early indication during the random access process, the uplink resource set in the random access process will be divided, resulting in a decrease in the utilization rate of the uplink resources. Therefore, it is necessary to consider how to make early indications flexibly. Summary of the invention

[0055] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.
[0056] (1) Random Access Channel (RACH) process:
[0057] like Figure 2 As shown, in the 5G system, the random access process adopts a four-step process similar to LTE:
[0058] Step 1: The UE sends a PRACH (Physical Random Access Channel) to the base station. The PRACH includes a random access preamble (ie, a first message message 1, MSG1).
[0059] Step 2: After the base station detects the access preamble sent by the UE, it sends a random access response (RAR), i.e., the second message (Message 2, Msg 2) to the UE to inform the UE of the physical uplink shared channel (PUSCH) resources that can be used to send the third message (Message 3, Msg 3), allocate a radio network temporary identifier (RNTI) to the UE, and provide the UE with a time advance command (Time Advance Command), etc.
[0060] Step 3: After receiving the random access response RAR, the UE sends a Msg 3 message on the PUSCH resource specified by the random access response message, which carries a UE-specific temporary identification information.
[0061] Step 4: The base station sends a fourth message (Message 4, Msg4) to the UE, which includes a contention resolution message and allocates uplink transmission resources to the UE. When the UE receives Msg4 sent by the base station, it detects whether the UE-specific temporary identifier sent by the UE in Msg 3 is included in the contention resolution message sent by the base station. If it is included, it indicates that the UE random access process is successful, otherwise it is considered that the random process has failed, and the UE needs to initiate the random access process again from the first step.
[0062] (2) Two-step RACH process
[0063] The delay overhead of the four-step RACH process is relatively large, which is not suitable for the low-latency and high-reliability scenarios in 5G. During the standardization process of NR, considering the characteristics of low-latency and high-reliability related services, a two-step RACH process, namely the Type-2 random access process, was introduced in R16. Compared with the four-step RACH process, the access delay can be reduced. Correspondingly, the four-step RACH process is called the Type-1 random access process.
[0064] The two-step RACH process is as follows Figure 3 As shown:
[0065] In the two-step RACH process, to put it simply, it is equivalent to combining the first and third steps of the four-step RACH process into the first step of the two-step RACH process: the UE sends a class A message (Message A, Msg A); and combining the second and fourth steps of the four-step RACH process into the second step of the two-step RACH process: the base station sends a class B message (Message B, MsgB) for response.
[0066] In the first step of two-step RACH, Msg A includes a preamble and a PUSCH part; in the second step of two-step RACH, Msg B includes a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH).
[0067] For Msg A, the UE needs to send preamble and PUSCH, where the RACH position (RACHoccasion, RO) where the Preamble is located is the same as the four-step RACH process. Through network configuration, its RO can be shared with the RO of the four-step RACH or configured separately.
[0068] The time-frequency resource where the physical uplink shared channel PUSCH is located is called the PUSCH occasion (PO). A PO can contain multiple PUSCH resource units (PRUs). A PRU contains PUSCH Resource and a demodulation reference signal (DMRS). DMRS contains a DMRS port and a DMRS sequence (applicable to Orthogonal Frequency Division Multiple Access (OFDMA)). PO is also configured through the network, and its period is the same as RO and is associated with it.
[0069] like Figure 4 As shown, the relative relationship in time-frequency position between the time slot PO slot where the physical uplink shared channel is located and the time slot (PRACH slot) where the associated RO is located is configured by the network, and the relative relationship includes an offset between the two.
[0070] (3) RedCap Terminal
[0071] The NR system is mainly designed to support eMBB services. Its main technology is to meet the needs of high speed, high spectrum efficiency, and large bandwidth. In fact, in addition to eMBB, there are many different types of services, such as sensor networks, video surveillance, wearables, etc. They have different requirements from eMBB services in terms of speed, bandwidth, power consumption, cost, etc.
[0072] The capabilities of terminals supporting these services are reduced compared to those supporting eMBB, such as reduced supported bandwidth, relaxed processing time, reduced number of antennas, and relaxed maximum modulation order. The NR system needs to be optimized for these services and corresponding low-capability terminals. Such terminals can be referred to as reduced capability (RedCap) terminals.
[0073] In LTE technology, there are similar system designs to support terminals with large number of connections, low power consumption and low cost, such as MTC and Narrow Band Internet of Things (NB-IoT). In NR system, it is hoped that similar technologies will be introduced to better support other types of services besides eMBB services using NR technology. For such low-complexity and low-cost terminals, one optimization that needs to be performed is coverage enhancement, which is used to improve the downlink and uplink coverage of such terminals.
[0074] (4) Network identification of RedCap UE
[0075] For the UE that initially accesses, after receiving the system message, it initiates a random access process to establish a Radio Resource Control (RRC) connection with the network. During this process, the network needs to identify the type of UE and obtain the UE-related capability information. The UE can indicate the type of UE to the network device in the following ways:
[0076] Indicated during the sending phase of Msg1, for example, through the initial uplink bandwidth part (BandwidthPart, BWP) where Msg 1 is transmitted, through independent PRACH resources, or by dividing an independent PRACH preamble set;
[0077] Indicated during the transmission phase of Msg3, for example, in the payload of the carried Msg 3PUSCH;
[0078] Indicated after the transmission of Msg4, such as the fifth message (Message5, Msg5) or as a capability report of the UE;
[0079] Indicated during the MsgA transmission phase of the 2-step RACH process.
[0080] For RedCap terminals, the network equipment cannot know their terminal type or capabilities during the initial access phase. Compared with non-RedCap terminals, the reception performance of the downlink channel of RedCap terminals is reduced due to the reduction in the number of receiving antennas. During the random access process, the network sends Msg2 and Msg4 to the terminal through the public channel. Since the type of the terminal is unknown, a conservative approach is that the network sets the transmission mode of the downlink channel according to the number of receiving antennas of the RedCap terminal, such as the scheduling resource size, modulation and coding scheme, etc. This will reduce the downlink spectrum efficiency.
[0081] The method for solving this problem includes that during the random access process, the RedCap terminal reports the type or capability of its terminal, so that the network can adopt the corresponding downlink channel transmission method. In general, the network can optimize the transmission of the RedCap UE earlier and improve the transmission efficiency by identifying the access of the RedCap UE earlier. This reporting method or indication method is hereinafter referred to as early indication. For example, through the indication of Msg1, the network can perform corresponding optimization for the RedCap UE when sending Msg2. However, the indication is made during the sending phase of Msg1, including distinguishing the RedCap terminal from the non-RedCap terminal through the preamble, the initial uplink BWP, and the difference of PRACH resources. This method will divide the resource set of the PRACH, which will cause the utilization rate of the PRACH resources to decrease, and cause the user capacity supported by the PRACH to decrease. When it is necessary to indicate multiple RedCap UE types or capabilities, further dividing the PRACH resources will further aggravate the problem. Based on this, it can be considered to allow the network to configure whether to indicate the type or capability of the RedCap terminal in advance during the random access process through system messages, and how to configure it needs to be considered.
[0082] The solution provided in the embodiments of the present application is mainly used to solve at least one of the above problems.
[0083] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present invention, the implementation of the embodiments of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not intended to limit the embodiments of the present invention.
[0084] Figure 5 is a schematic flow chart of an information indication method according to an embodiment of the present application. The method can optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.
[0085] Step S510, the terminal device receives first indication information from the network device;
[0086] Step S520: The terminal device determines, based on the first indication information, whether to provide an advance indication of the low-capability terminal in the first uplink information of the random access process.
[0087] Corresponding to the above method, the embodiment of the present application also provides an information indication method, specifically referring to Figure 6 , the method comprising:
[0088] Step S610, the network device sends first indication information to the terminal device;
[0089] The first indication information is used to instruct the terminal device to determine whether to make an advance indication of the low-capability terminal in the first uplink information of the random access process.
[0090] Optionally, the first indication information may be carried by a system message.
[0091] Optionally, the advance indication of the low-capability terminal includes indicating in advance the type and / or capability of the RedCap terminal.
[0092] Optionally, the first uplink information includes a first physical random access channel PRACH and / or a first physical uplink shared channel PUSCH.
[0093] Optionally, the first PRACH includes: a PRACH of a four-step random access process.
[0094] That is to say, for the four-step random access process, the terminal device can optionally determine whether to make an advance indication in the PRACH, that is, Msg1, based on the first indication information.
[0095] Optionally, the first PRACH includes: PRACH in Msg A of a two-step random access process.
[0096] That is to say, for the two-step random access process, the terminal device can optionally determine whether to make an advance indication in the PRACH in MsgA based on the first indication information.
[0097] Optionally, the first PUSCH includes: PUSCH in Msg3 of a four-step random access process.
[0098] That is to say, for the four-step random access process, the terminal device can optionally determine whether to make an advance indication in the PUSCH in Msg3 based on the first indication information.
[0099] Optionally, the first PUSCH includes: PUSCH of Msg A of a two-step random access process.
[0100] That is to say, for the two-step random access process, the terminal device can optionally determine whether to make an advance indication in the PUSCH in MsgA based on the first indication information.
[0101] In actual applications, the terminal device may also determine whether to jointly perform advance indication in the first PRACH and the first PUSCH during the random access process based on the first indication information.
[0102] In the embodiment of the present application, the first indication information can be used for different purposes in different scenarios. Several specific examples are provided below:
[0103] Example 1: The first indication information is used to indicate whether to perform advance indication of the RedCap terminal during the random access process.
[0104] For example, in a case where the uplink information configured by the system for advance indication is the above-mentioned first uplink information, the terminal device determines whether to make an advance indication based on the first indication information.
[0105] One implementation is that the first indication information explicitly indicates whether the RedCap terminal can make an advance indication during the random access process. For example, the first indication information is added to the system message, with bit 1 indicating that the terminal device makes an advance indication, and bit 0 indicating that the terminal device does not make an advance indication.
[0106] Another implementation manner is that the first indication information implicitly indicates whether the RedCap terminal can perform advance indication during the random access process.
[0107] Optionally, the first indication information is used to configure a first uplink resource for the terminal device, wherein the first uplink resource is used to send uplink information in a random access process;
[0108] The terminal device determines, according to the first indication information, whether to perform an advance indication of the low-capability terminal in the first uplink information of the random access process, including:
[0109] In a case where the first uplink resource includes an uplink resource of a low-capability terminal, the terminal device determines to perform an advance indication of the low-capability terminal in the first uplink information of the random access process.
[0110] That is, in the case where the first uplink resource includes an uplink resource of a low-capability terminal, the first indication information is further used to instruct the terminal device to determine to perform an advance indication of the low-capability terminal in the first uplink information.
[0111] Optionally, when the first uplink resources do not include uplink resources for low-capability terminals, the terminal device determines not to make an advance indication of the low-capability terminal in the first uplink information of the random access process.
[0112] For example, the network device configures resources for sending PRACH and / or PUSCH for the RedCap terminal through the first indication information, including resources used by non-RedCap terminals, and optionally, resources used by RedCap terminals. When the network configures the resources used by the RedCap terminal, it implicitly configures the terminal device to make an advance indication of the RedCap terminal during the random access process, such as making an advance indication in a pre-specified first uplink information. Exemplarily, when the terminal device sends uplink information using the resources configured by the first indication information, the network device can identify the terminal device as a RedCap terminal.
[0113] Example 2: The first indication information is used to configure uplink information for advance indication of a RedCap terminal.
[0114] For example, when the system has configured or defaulted that the terminal device can make advance indications, the first indication information is used to configure the uplink information used for making advance indications. Based on this, the terminal device determines whether to make advance indications in the first uplink information or other uplink information based on the first indication information.
[0115] For another example, when the network device configures the terminal device to perform advance indication through the second indication information, the terminal device determines whether to perform advance indication in the first uplink information or other uplink information based on the first indication information. Specifically, in the above step S520, the terminal device determines whether to perform advance indication of the low-capability terminal in the first uplink information of the random access process according to the first indication information, including:
[0116] In case of determining to perform advance indication of the RedCap terminal in the random access process according to the received second indication information, the terminal device determines whether to perform advance indication of the RedCap terminal in the first uplink information of the random access process according to the first indication information.
[0117] Correspondingly, in the above step S610, the network device sends the first indication information to the terminal device, including:
[0118] In case of sending the second indication information to the terminal device, the network device sends the first indication information to the terminal device;
[0119] The second indication information is used to instruct the terminal device to determine to make an advance indication of a low-capability terminal during a random access process.
[0120] That is, the network device indicates to the terminal device through the second indication information that it can make an advance indication. On this basis, the terminal device determines whether to make an advance indication in the first uplink information or other uplink information based on the first indication information.
[0121] Exemplarily, the second indication information may be carried by a system message.
[0122] Exemplarily, the second indication information may explicitly indicate that the terminal device can make an advance indication. For example, dedicated information is set in the system message to indicate whether the terminal device can make an advance indication. One example is that when the dedicated information is the second indication information, such as bit 1, the terminal device can make an advance indication; when the dedicated information is other information, such as bit 0, the terminal device does not make an advance indication. Another example is that the dedicated information is the second indication information, and when the second indication information is received, the terminal device can make an advance indication; when the second indication information is not received, the terminal device does not make an advance indication.
[0123] Optionally, the first indication information may be explicitly configured as uplink information for early indication. Specifically, the first indication information is used to indicate third uplink information, and the third uplink information is used to provide early indication to the low-capability terminal;
[0124] The terminal device determines, according to the first indication information, whether to perform an advance indication of the low-capability terminal in the first uplink information of the random access process, including:
[0125] In a case where the third uplink information includes the first uplink information, the terminal device determines to perform advance indication of the low-capability terminal in the first uplink information.
[0126] In other words, in a case where the third uplink information includes the first uplink information, the first indication information is further used to instruct the terminal device to determine to perform an advance indication of the low-capability terminal in the first uplink information.
[0127] Optionally, when the third uplink information does not include the first uplink information, the terminal device determines not to make an advance indication of the low-capability terminal in the first uplink information.
[0128] For example, the candidates for the third uplink information are the first PRACH and the first PUSCH. The first indication information directly indicates that the third uplink information is the first PRACH and / or the first PUSCH. In the case where the third uplink information includes the first PRACH, the terminal device determines to perform an advance indication of the RedCap terminal in the first PRACH; in the case where the third uplink information includes the first PUSCH, the terminal device determines to perform an advance indication of the RedCap terminal in the first PUSCH; in the case where the third uplink information includes the first PRACH and the first PUSCH, the terminal device determines to perform an advance indication of the RedCap terminal jointly in the first PRACH and the first PUSCH.
[0129] Example 3: The first indication information is used to indicate whether to perform advance indication of the RedCap terminal during the random access process, and to configure uplink information used for performing advance indication of the RedCap terminal.
[0130] For example, based on the fact that the first indication information in Example 1 explicitly indicates whether the RedCap terminal can make an advance indication during the random access process, in combination with Example 2, the first indication information may also explicitly configure uplink information for making an advance indication.
[0131] For example, in Example 1, the first indication information implicitly indicates whether the RedCap terminal can make an advance indication during the random access process by configuring the first uplink resource. In combination with Example 2, the first indication information can also explicitly configure the uplink information for making an advance indication.
[0132] For another example, in Example 1, the first indication information implicitly indicates whether the advance indication of the RedCap terminal can be performed during the random access process by configuring the first uplink resource. The first indication information can also implicitly configure the uplink information used for the advance indication. Exemplarily, in the example where the first indication information is used to configure the first uplink resource, the first uplink resource is used to send the first uplink information.
[0133] Specifically, the network device configures the transmission resources of the first PRACH for the RedCap terminal through the first indication information, which includes the transmission resources of the first PRACH used by non-RedCap terminals, and optionally, may also include the transmission resources of the first PRACH used by RedCap terminals. When the network configures the transmission resources of the first PRACH used by the RedCap terminal, the terminal device is implicitly configured to make an advance indication of the RedCap terminal through the first PRACH. When the network does not configure the transmission resources of the first PRACH used by the RedCap terminal, it is implicitly configured not to make an advance indication of the RedCap terminal type or capability through the first PRACH. Therefore, the RedCap terminal can determine whether to make an advance indication of the RedCap terminal type or capability through the first PRACH based on whether the network has configured the transmission resources of the first PRACH used by the RedCap terminal.
[0134] Similarly, the network device configures the resources for sending the above-mentioned first PUSCH for the RedCap terminal through the first indication information, which includes the sending resources of the first PUSCH used by non-RedCap terminals, and optionally, may also include the sending resources of the first PUSCH used by RedCap terminals. When the network configures the sending resources of the first PUSCH used by the RedCap terminal, the terminal device is implicitly configured to make an advance indication of the RedCap terminal through the first PUSCH. When the network does not configure the sending resources of the first PUSCH used by the RedCap terminal, it is implicitly configured not to make an advance indication of the RedCap terminal type or capability through the first PUSCH. Therefore, the RedCap terminal can determine whether to make an advance indication of the RedCap terminal type or capability through the first PUSCH based on whether the network has configured the sending resources of the first PUSCH used by the RedCap terminal.
[0135] Optionally, in the above example, the information indication method may further include:
[0136] In a case where the first uplink resources do not include uplink resources for the low-capability terminal, the terminal device determines to perform an advance indication of the low-capability terminal in the second uplink information of the random access process.
[0137] That is, in a case where the first uplink resource does not include uplink resources for the low-capability terminal, the first indication information is further used to instruct the terminal device to determine to make an advance indication of the low-capability terminal in the second uplink information of the random access process.
[0138] Exemplarily, when the first uplink information includes the first PRACH, the second uplink information includes the first PUSCH.
[0139] Exemplarily, when the first uplink information includes the first PUSCH, the second uplink information includes the first PRACH.
[0140] For example, the network device configures the transmission resources of the first PRACH for the RedCap terminal through the first indication information, which includes the transmission resources of the first PRACH used by non-RedCap terminals, and optionally, may also include the transmission resources of the first PRACH used by RedCap terminals. When the network configures the transmission resources of the first PRACH used by the RedCap terminal, the terminal device is implicitly configured to make an advance indication of the RedCap terminal through the first PRACH. When the network does not configure the transmission resources of the first PRACH used by the RedCap terminal, the advance indication of the RedCap terminal type or capability through the first PUSCH is implicitly configured.
[0141] For another example, the network device configures the transmission resources of the first PUSCH for the RedCap terminal through the first indication information, which includes the transmission resources of the first PUSCH used by non-RedCap terminals, and optionally, may also include the transmission resources of the first PUSCH used by RedCap terminals. When the network configures the transmission resources of the first PUSCH used by the RedCap terminal, it implicitly configures the terminal device to make an advance indication of the RedCap terminal through the first PUSCH. When the network does not configure the transmission resources of the first PUSCH used by the RedCap terminal, it implicitly configures the advance indication of the RedCap terminal type or capability through the first PRACH.
[0142] Optionally, in an embodiment of the present application, the advance indication of the low-capability terminal includes indicating the type and / or capability of the low-capability terminal based on predetermined information, that is, indicating that the device type of the terminal device is a low-capability terminal and / or indicating the capability of the terminal device based on predetermined information.
[0143] Optionally, the predetermined information includes at least one of the following:

[0154] Exemplarily, performing an advance indication of a low-capability terminal in the first PUSCH includes at least one of the following:

[0158] Different PUSCH resource configurations are used to carry the type and / or capability of low-capability terminals;

Using at least one of the above embodiments, the terminal device can determine whether to make an advance indication of the low-capability terminal in the first uplink information of the random access process based on the first indication information sent by the network device. Therefore, by configuring the first indication information, the advance indication and the uplink information used for the advance indication can be flexibly configured, which facilitates the network device to optimize the terminal type while avoiding excessive segmentation of the uplink resources in the random access process, resulting in a decrease in utilization.
