Detailed ways

In order to have a more detailed understanding of the characteristics and technical content of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present application.

Before describing in detail the uplink access method provided in the embodiments of the present application, a brief description of the relevant information of the uplink access method in the related technology will be given first.

With people's pursuit of speed, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP International Standards Organization began to develop 5G. The main application scenarios of 5G are: Enhance Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC).

eMBB still aims for users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized, and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of the module.

The New Radio (NR) system can also be deployed independently. In order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, a new Radio Resource Control (RRC) state is defined, namely RRC-Inactive (Deactivated) state. Among them, in the RRC-Idle state, the mobility is cell reselection based on terminal equipment, the paging process is initiated by the Core Network (Core Network, CN), and the paging area is configured by the CN. There is no terminal device context and no RRC connection on the network device side. In the RRC-Inactive state, the mobility is based on the cell reselection of the terminal device, there is a connection between CN-NR, the terminal device context exists on a certain network device, and the paging process is controlled by the Radio Access Network (Radio Access Network, RAN) trigger, the RAN-based paging area is managed by the RAN, and the network equipment can know that the location of the terminal device is based on the RAN-based paging area level. In the RRC-Connected state, there is an RRC connection, and there is a terminal device context between the network device and the terminal device. The network device knows that the location of the terminal device is at the specific cell level; mobility is the mobility controlled by the network device, and the network device Unicast data can be transmitted with terminal equipment.

NR-light equipment is introduced in R17. NR-light equipment can be composed of three scenarios, including:

1. Industrial Wireless Sensors (IWS). Compared with URLLC devices, IWS has relatively low latency and reliability. At the same time, the cost and power consumption of the devices are also lower than those of URLLC devices and eMBB devices.

2. Video surveillance equipment is mainly used for video surveillance in smart cities, industrial factories, and data collection and processing in smart cities to facilitate more effective monitoring and control of urban resources and provide urban residents with more effective service.

3. Wearables. Wearables can at least include smart watches, electronic health equipment, and some medical monitoring equipment. The commonality of wearable devices is the small size of the device.

The common requirements of the above three scenarios are:

1. The equipment cost is low; by reducing the bandwidth and receiving antenna, the cost and complexity of the equipment are reduced.

2. The size of the equipment; it has a smaller equipment size.

3. Coverage rate; it is required to achieve a coverage rate equivalent to R15 or R16; if the coverage loss is caused by reducing the receiving antenna, or reducing the bandwidth, or reducing the power level, or reducing the complexity of the terminal equipment, the coverage loss needs to be compensated.

The non-common requirements of the above three scenarios are:

1. Industrial wireless sensors: The reliability requirement is 99.99%, and the end-to-end delay requirement is 100ms. The bit rate requirement is 2Mbps; the device is stationary; the battery life is several years; for safety-related sensors, the delay requirement is 5-10ms.

2. Video Survaillance: The bit rate requirement is 2-4Mbps, the delay requirement is <500ms, and the reliability requirement is 99%-99.9%. For some high-end video rates, the requirement is 2-4Mbps, and the uplink traffic is relatively large.

3. Wearables: The speed requirement is 150Mbps/50Mbps.

The following briefly describes the bandwidth part (BandWith Part, BWP):

The maximum channel bandwidth supported in the NR system can be up to 400MHZ wideband carrier. If the terminal device keeps working on the broadband carrier, the power consumption of the terminal device is very large. Adjusting the radio frequency (RF) bandwidth of the terminal device according to the actual throughput of the terminal device can optimize the power consumption of the terminal device, and then introduce BWP.

A terminal device in a connected state can only have at most one activated downlink BWP and one activated uplink BWP at a time. The network equipment can configure up to 4 uplink BWPs and up to 4 downlink BWPs for connected terminal devices. For Frequency Division Dual (FDD) systems, there is no association between the uplink BWP and the downlink BWP. relationship. For example, a network device can configure 4 uplink BWPs (indexes are 0, 1, 2, 3) and 4 downlink BWPs (0, 1, 2, 3) for a connected terminal device, and the currently activated uplink BWP index It can be 0, and the index of the currently activated downlink BWP can be 1. If the downlink BWP is switched to another BWP through Downlink Control Information (DCI), for example, switching from the currently activated downlink BWP 1 to the downlink BWP 2, uplink BWP can remain unchanged.

The terminal equipment in the idle state and in the deactivated state obtains the master information block (Master Information Block, MIB) and the system information block (System Information Block, SIB1) information. The SIB1 indicates the relevant configuration information of the initial (initial) BWP used for the initial access of the terminal device, which includes the initial uplink BWP and the initial downlink BWP. In the uplink BWP configuration, the network device configures a random access resource (RACH-ConfigCommon) for the initial access terminal device, and there is a correspondence between the random access resource and the SSB. The network device controls the selection of random access resources for the terminal device by configuring an RSRP threshold (RSRP-Threshold SSB). When the random access process is triggered, the terminal device selects an SSB whose RSRP measurement value meets the above RSRP threshold, and then follows the random access The corresponding relationship between the resource and the SSB selects the corresponding random access resource to send a preamble (preamble), that is, sends Msg1, and receives the random access response message sent by the network device on the selected SSB, that is, receives Msg2.

In order to improve the uplink coverage on the high frequency band of the NR system, a Supplementary Uplink (SUL) frequency is introduced. Because the uplink power of the terminal equipment is limited, and the frequency of the frequency spectrum of the NR system is high, the uplink coverage of the terminal equipment will be limited. In order to improve the uplink coverage of the terminal equipment, the LTE spectrum (relatively low frequency) is used as the uplink spectrum to improve the uplink coverage.

In addition, two uplink carriers and one downlink spectrum belong to the same cell, and there is only one physical uplink shared channel (PUSCH) transmission at the same time. Unless the network device explicitly instructs the terminal device which uplink carrier to use, the terminal device decides the choice of the terminal device according to the measurement threshold. The threshold is broadcast configuration in the system broadcast. The two uplink carriers can be dynamically switched through DCI instructions. A terminal device in an idle state or a deactivated state determines whether to use a normal uplink (Normal Uplink, NUL) carrier or SUL for initial access based on the RSRP size of the serving cell.

This application provides an uplink access method. The uplink access method in the embodiments of this application can be applied to various communication systems, such as: Global System of Mobile Communication (GSM) system, Code Division Multiple Access (Code Division) Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE frequency division Duplex (Frequency Division Duplex, FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) Communication system or 5G system, etc.

An optional processing procedure of the uplink access method applied to terminal equipment provided by the embodiment of the present application, as shown in FIG. 2, includes the following steps:

Step S201: The terminal device determines a target carrier for initial access or data transmission among the normal uplink carrier and the at least one first supplementary uplink carrier according to the first information.

In some embodiments, the first information includes at least one of the following: selection factor information of the NUL carrier, selection factor information of the first SUL carrier, and RSRP gate corresponding to the first SUL carrier. Limit, the RSRP threshold range corresponding to the first SUL carrier, the corresponding relationship between the type of the terminal equipment and the normal uplink carrier, the corresponding relationship between the type of the terminal equipment and the first SUL carrier, and the type of service The corresponding relationship with the normal uplink carrier, the corresponding relationship between the service type and the first SUL carrier, and the first indication information sent by the network device.

The uplink access method provided by the embodiment of the present application may further include:

Step S200: The terminal device receives the first system message sent by the network device, where the first system message is used to indicate the information of the second SUL carrier.

In some embodiments, the first system message may be SIB1; the number of the second SUL carrier is at least one.

In some embodiments, the first system message may also carry first information; that is, the network device sends the first information to the terminal device through the first system message.

Step S200', the terminal device determines the information of the first SUL carrier based on the information of the second SUL carrier.

In some embodiments, the terminal device determines that in the second SUL carrier, the SUL carrier supported by the terminal device is the first SUL carrier. For example, a network device broadcasts X second SUL carriers through SIB1, and among the X second SUL carriers, Y second SUL carriers are carriers that the terminal device can support according to its own wireless capabilities; then the terminal device It is determined that the Y second SUL carriers are the first SUL carriers. If there is at least one carrier that the terminal device can support in the second SUL carrier, the terminal device confirms that the cell is an accessible cell; if there is no carrier that the terminal device can support in the second SUL carrier, the terminal device considers the cell to be Forbid access, give up camping on the cell, and need to initiate a cell reselection process.

The following describes the implementation process of the terminal device determining a target carrier for initial access or data transmission based on different contents included in the first information.

1. For the case where the first information includes the selection factor information of the NUL carrier and the selection factor information of the second SUL carrier, the terminal device may first determine the selection factor information of the first SUL carrier.

If the terminal device determines that the number of the first SUL carrier is the same as the number of the second SUL carrier, the terminal device determines that the selection factor information of the first SUL carrier is the same as the selection factor information of the second SUL carrier.

If the terminal device determines that the number of the first SUL carrier is less than the number of the second SUL carrier, the terminal device may recalculate the selection factor information of the first SUL carrier. For example, the terminal device determines the selection factor information of one NUL carrier and the selection factor information of X second SUL carriers through the first system message, and the selection factor value of one NUL carrier and the selection of X second SUL carriers The sum of the factor values is 1. If the terminal device determines that Y second SUL carriers are the first SUL carrier from the X second SUL carriers, the terminal device can re-determine the selection factor information of one NUL carrier and the Y second SUL carriers. SUL carrier selection factor information. In specific implementation, the selection factor information of the one NUL carrier and the selection factor information of the Y second SUL carriers may be normalized to obtain the selection factor information of the new NUL carrier and the Y first SUL carriers The selection factor information. For example, if the value of X is 2, the value of Y is 1, the selection factor value of one NUL carrier is 0.2, and the value of the selection factor information of two second SUL carriers is 0.3 and 0.5 respectively, then the normalized new The value of the selection factor of the NUL carrier is 0.4, and the value of the selection factor information of a first SUL carrier is 0.6.

In some embodiments, the selection factor information of the NUL carrier is the same as the selection factor information of the first SUL carrier; for example, if there are three first SUL carriers, the selection factor values of the NUL carrier and the SUL carrier are both 0.25 . Alternatively, the selection factor information of each of the first SUL carriers is the same, and the selection factor information of the NUL carrier is the difference between 1 and the sum of the selection factor information of all the first SUL carriers; for example, there are 4 For a SUL carrier, the selection factor information of each SUL carrier is a, and the selection factor information of the NUL carrier is (1-4a). Alternatively, the selection factor information of the NUL carrier and the selection factor information of each of the first SUL carriers are independent of each other; for example, the selection factor information of the NUL carrier and the selection factor information of the three SUL carriers are 0.2, 0.3, 0.4, and respectively. 0.1.

After determining the selection factor information of the first SUL carrier and the selection factor information of the NUL carrier, the terminal device in the Inactive or Idle state can at least determine the target carrier for initial access through the following scheme:

1) The terminal device randomly determines a target carrier for initial access among the NUL carrier and all the first SUL carriers with the same probability. For example, if there is one NUL carrier and four first SUL carriers, the probability of the NUL carrier and each first SUL carrier being determined as the target carrier is both 25%.

2) Based on the selection factor information of the NUL carrier and the selection factor information of the first SUL carrier, the terminal device randomly determines one of the NUL carriers and all the first SUL carriers for initial access Target carrier. For example, if the selection factor value of the NUL carrier is 0.4, the selection factor value of a first SUL carrier is 0.6, and if the random number is 0.8, and 0.8 belongs to the range of 0.6 to 1, the terminal device determines the first SUL carrier Target carrier used for tree pool access.

3) In the case that the RSRP of the serving cell of the terminal device is greater than the RSRP threshold corresponding to the NUL carrier, the terminal device determines that the NUL carrier is the target carrier for initial access; for example, The first information also includes the RSRP threshold value corresponding to the NUL carrier. If the RSRP of the serving cell of the terminal device is greater than the RSRP threshold value corresponding to the NUL carrier, the terminal device determines that the NUL carrier is used for initial connection. Incoming target carrier. In the case that the RSRP of the serving cell of the terminal device is less than or equal to the RSRP threshold corresponding to the NUL carrier, the terminal device randomly determines one of the first supplementary uplink carriers with the same probability. The target carrier for initial access; or, the terminal device randomly determines a target carrier for initial access among all the first supplementary uplink carriers based on the selection factor information of the first supplementary uplink carrier.

4) In the case that the RSRP of the serving cell of the terminal device is not less than the RSRP threshold corresponding to the NUL carrier, the terminal device determines that the NUL carrier is the target carrier for initial access. For example, if the RSRP of the serving cell of the terminal device is not less than the RSRP threshold corresponding to the NUL carrier, the terminal device determines that the NUL carrier is the target carrier for initial access. Wherein, not less than means greater than or equal to; the RSRP of the serving cell of the terminal device is not less than the RSRP threshold corresponding to the NUL carrier, that is, the RSRP of the serving cell of the terminal device is greater than or equal to the NUL carrier The corresponding RSRP threshold. In the case that the RSRP of the serving cell of the terminal device is less than the RSRP threshold corresponding to the normal uplink carrier, the terminal device randomly determines one of all the first supplementary uplink carriers with the same probability to be used for The target carrier for initial access; or, the terminal device randomly determines a target carrier for initial access among all the first supplementary uplink carriers based on the selection factor information of the first supplementary uplink carrier.

In the embodiment of this application, the network device broadcasts the information of multiple SUL carriers to the terminal device through the first system message. The introduction of multiple SUL carriers can increase the uplink capacity of the communication system; the terminal device randomly selects the NUL carrier or the SUL carrier The probability of multiple terminal devices selecting the same SUL carrier or NUL carrier can be reduced, and the problem of limited random access resource capacity can be alleviated.

2. For the case where the first information includes the RSRP threshold value corresponding to the first SUL carrier and/or the RSRP threshold value range corresponding to the first SUL carrier, the terminal device in the Inactive or Idle state can at least pass the following The plan determines the target carrier for initial access:

1) The terminal device determines that the first SUL carrier corresponding to the RSRP threshold range to which the RSRP of the serving cell of the terminal device belongs is a candidate carrier for initial access.

In some embodiments, the RSRP threshold range includes a first RSRP threshold and a second RSRP threshold. The RSRP threshold range to which the RSRP of the serving cell of the terminal device belongs may include any one of the following: the first RSRP threshold <the RSRP of the serving cell <the second RSRP threshold, and the first RSRP threshold ≤ the serving cell The RSRP<the second RSRP threshold, the first RSRP threshold<the RSRP of the serving cell≤the second RSRP threshold, and the first RSRP threshold≤the RSRP of the serving cell≤the second RSRP threshold.

2) The terminal device receives the second indication information sent by the network device, and the terminal device determines the candidate carrier for initial access according to the second indication information.

In some embodiments, the second indication information is used to instruct the terminal device to determine a strategy for the carrier for initial access based on the RSRP threshold; the terminal device determines the strategy for initial access based on the RSRP threshold. The strategy for the initial access carrier includes:

In the case that the RSRP of the serving cell of the terminal device is greater than the RSRP threshold, the first supplementary uplink carrier corresponding to the RSRP threshold is a candidate carrier for initial access.

Or, in the case that the RSRP of the serving cell of the terminal device is not less than the RSRP threshold, the first supplementary uplink carrier corresponding to the RSRP threshold is a candidate carrier for initial access; wherein, no Less than means greater than or equal to; the RSRP of the serving cell of the terminal device is not less than the RSRP threshold, that is, the RSRP of the serving cell of the terminal device is greater than or equal to the RSRP threshold.

Alternatively, in a case where the RSRP of the serving cell of the terminal device is less than the RSRP threshold, the first supplementary uplink carrier corresponding to the RSRP threshold is a candidate carrier for initial access.

Or, in the case that the RSRP of the serving cell of the terminal device is not greater than the RSRP threshold, the first supplementary uplink carrier corresponding to the RSRP threshold is a candidate carrier for initial access; wherein, no Greater than means less than or equal to; the RSRP of the serving cell of the terminal device is not greater than the RSRP threshold, that is, the RSRP of the serving cell of the terminal device is less than or equal to the RSRP threshold.

In some embodiments, the number of candidate carriers determined based on the RSRP threshold value corresponding to the first SUL carrier and/or the RSRP threshold value range corresponding to the first SUL carrier is 1, the candidate carrier is the The target carrier for initial access.

In some embodiments, the number of candidate carriers determined based on the RSRP threshold value corresponding to the first SUL carrier and/or the RSRP threshold value range corresponding to the first SUL carrier is at least two, the terminal device may further Using the above-mentioned solution for the terminal device to determine the target carrier based on the selection factor information of the NUL carrier and the selection factor information of the first SUL carrier, one carrier is selected from the multiple candidate carriers as the target carrier for initial access.

The terminal device further uses the above-mentioned terminal device's solution for determining the target carrier based on the selection factor information of the NUL carrier and the selection factor information of the first SUL carrier, and selects one carrier among the multiple candidate carriers as the target for initial access Before the carrier, the terminal device may first perform normalization processing on the selection factor information of all the candidate carriers to obtain the new selection factor information of the candidate carrier; the new selection factor information and the selection before the normalization processing There are differences in factor information.
