Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and particularly relates to an access resource determination method, an access resource determination device and a storage medium. BACKGROUND

[0002] In a wireless communication system, for the low rate and high latency scenarios of Internet of Things (IoT) services, Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT) technologies are proposed. Due to the development of IoT services, MTC and NB-IoT technologies cannot meet the current demand of IoT services for rate and latency. Therefore, a new terminal, Reduced capability (Redcap) terminal, or simply referred to as NR-lite, is designed to cover the service requirements of IoT.

[0003] In the related art, when the initial (Initial) bandwidth part (BWP) configured by the system to a terminal with normal transceiving capability is relatively large, a separate Initial BWP needs to be configured for a Redcap terminal with limited transceiving bandwidth. In order to enable the network to identify the coverage enhanced terminal in advance, the physical random access channel (PRACH) resources in the BWP need to be divided. Therefore, the PRACH resources need to be divided for different BWPs, which causes problems such as unreasonable PRACH resource reservation and PRACH resource waste. SUMMARY

[0178] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is with reference to the drawings, in which like numerals indicate like elements, unless otherwise described in detail. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples in accordance with some aspects of the present disclosure as detailed in the appended claims.

[0179] Figure 1 is a block diagram of a network device and terminal communication system architecture according to an exemplary embodiment. The communication method provided by the present disclosure can be applied to Figure 1 the communication system architecture shown. As shown in Figure 1 , the network side device can send signaling based on Figure 1 the architecture shown.

[0180] It can be understood that Figure 1 the network device and terminal communication system shown is only illustrative, and other network devices can also be included in the wireless communication system, such as core network devices, wireless relay devices, and wireless backhaul devices, etc., which are not shown in Figure 1 . The number of network devices and the number of terminals included in the wireless communication system are not limited by the embodiments of the present disclosure.

[0181] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance (CSMA / CA), and the like. Depending on the capacity, rate, latency, and the like of different networks, the networks can be classified into 2G (English: generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. The 5G network can also be referred to as a new radio network (NR). For the convenience of description, the wireless communication network can be referred to as a network in the present disclosure.

[0182] Further, the network device involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission and reception point (TRP), and the like. It can also be a gNB in an NR system, or it can also be a component or a part of a device that constitutes a base station, and the like. When it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form of the network device are not limited in the embodiments of the present disclosure.

[0183] Further, the terminal involved in the present disclosure, which can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., is a device that provides voice and / or data connectivity to a user, for example, the terminal can be a handheld device having wireless connection function, a vehicle-mounted device, etc. At present, some examples of the terminal are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the present disclosure embodiments do not limit the specific technology and specific device form adopted by the terminal.

[0184] In a communication system such as a Long Term Evolution (LTE) 4G (fourth generation mobile communication technology) system, two major technologies, MTC (Machine Type Communication) and NB-IoT (Narrow Band Internet of Things), are proposed to support Internet of Things services. These two technologies are mainly aimed at low-rate and high-latency scenarios, such as meter reading and environmental monitoring scenarios. Among them, the maximum transmission rate supported by the NB-IoT technology is several hundred kbps (kilobits per second), and the maximum transmission rate supported by the MTC technology is several Mbps (megabits per second). However, with the continuous development of Internet of Things services, such as the popularity of video monitoring, smart home, wearable devices, and industrial sensing and monitoring services, these services usually require transmission rates of tens of Mbps to 100 Mbps, and the above services also have relatively high requirements for latency. Therefore, the MTC technology and the NB-IoT technology in LTE are difficult to meet the requirements of the above services. Based on this situation, a new type of user equipment is proposed in 5G NR to cover the requirements of such mid-end Internet of Things devices. In the current 3GPP (3rd Generation Partnership Project) standardization, this new terminal type is called Reduced capability (Redcap) terminal or simply NR-lite (New Radio-Lite). The bandwidth configured for the Redcap terminal is relatively small. Therefore, for the Redcap terminal, due to the reduction in bandwidth size, the antenna radiation efficiency may be reduced, resulting in a loss of coverage, and therefore coverage enhancement is needed.

[0185] When there are both normal terminals (such as normal 5G terminals) and Redcap terminals in a communication system, if the Initial UL BWP configured by the communication network system for the normal terminals is greater than 20 MHz, a separate Initial UL BWP needs to be configured for the Redcap terminals.

[0186] For the case of small size bandwidth Redcap terminal, the antenna efficiency of its transceiver will have 3db loss, so in some cases, the information 3 (Msg.3), physical uplink shared channel (PUSCH) and other channels need to be covered. At the same time, in order for the network device to make targeted configuration for Redcap terminal, early indication is needed for Redcap terminal, for example, the division of PRACH resources can be used for early indication.

[0187] For the case of normal terminal, in the related art, all normal terminals share an Initial UL BWP. However, a part of normal terminals also need to be covered. Therefore, in order for the network device to identify the terminal in advance, similar to the terminal that needs to be covered, the PRACH resource also needs to be divided.

[0188] Based on the above situation, Figure 2 is a schematic diagram of the division of PRACH resources shown by an exemplary embodiment of the present disclosure. The Initial UL BWP corresponding to the Redcap terminal needs to be divided according to different coverage enhancement levels, and the Initial UL BWP corresponding to the normal terminal also needs to be divided according to different coverage enhancement levels. As shown in Figure 2 For the Initial UL BWP corresponding to the normal terminal, according to different coverage enhancement levels, for example, coverage enhancement level 1, coverage enhancement level 2, coverage enhancement level 3. Of course, coverage enhancement level 1 can also be understood as transmitting once, or not using coverage enhancement. Therefore, the PRACH resources are divided into PRACH resources corresponding to the normal terminal with coverage enhancement level 1, PRACH resources corresponding to the normal terminal with coverage enhancement level 2, and PRACH resources corresponding to the normal terminal with coverage enhancement level 3. For the Initial UL BWP corresponding to the Redcap terminal, according to different coverage enhancement levels, for example, coverage enhancement level 1, coverage enhancement level 2, coverage enhancement level 3. Of course, coverage enhancement level 1 can also be understood as transmitting once, or not using coverage enhancement. Therefore, the PRACH resources are divided into PRACH resources corresponding to the Redcap terminal with coverage enhancement level 1, PRACH resources corresponding to the Redcap terminal with coverage enhancement level 2, and PRACH resources corresponding to the Redcap terminal with coverage enhancement level 3.

[0189] Therefore, the PRACH resource reservation is unreasonable, and PRACH resources are wasted. Therefore, the present disclosure proposes an access resource determination method. By sharing the corresponding PRACH resource corresponding to the Initial UL BWP of the Redcap terminal when the normal terminal is covered, the effect of reducing the division of the PRACH resource is achieved.

[0190] Figure 3 is a flowchart of an access resource allocation method according to an exemplary embodiment. As shown in Figure 3 , the access resource allocation method is used in a network device, comprising the following steps.

[0191] In step S11, a first BWP is determined.

[0192] In an embodiment of the present disclosure, the first BWP includes at least a physical random access channel PRACH resource for a first type of terminal that needs to be covered, and / or a PRACH resource for a second type of terminal.

[0232] In step S51, the first indication message is received.

[0233] In the embodiments of the present disclosure, the first indication message comprises the transceiving capability information associated with the second type terminal. The second type terminal needs to report its own transceiving capability information. The network device determines the access resource of the second type terminal according to the received transceiving capability information of the second type terminal.

[0234] In an example embodiment of the present disclosure, the network device can receive the first indication message based on the access message. For example, in the access process, the network device receives the first indication message sent by the terminal through the message Msg.3.

[0235] In an example embodiment of the present disclosure, the network device can receive the first indication message based on the radio resource control (RRC) signaling. For example, after the terminal completes the access, the network device receives the first indication message based on the RRC signaling.

[0236] Based on the same / similar concept, the embodiments of the present disclosure also provide an access resource determination method.

[0237] Figure 9 is a flowchart of an access resource allocation method according to an example embodiment. As shown in Figure 9 The access resource allocation method is used in a terminal, comprising the following steps.

[0238] In step S61, the first BWP is determined.

[0239] In the embodiments of the present disclosure, the terminal is a first type terminal which needs to perform coverage enhancement, or the terminal is a second type terminal. The first BWP at least comprises PRACH resources for the first type terminal which needs to perform coverage enhancement, and / or PRACH resources for the second type terminal. The capability of the first type terminal is greater than the capability of the second type terminal.

[0240] In an example embodiment of the present disclosure, the terminal determines its terminal type. If the terminal is a first type terminal which needs to perform coverage enhancement, the terminal determines the first BWP, and then determines the PRACH resources corresponding to the coverage enhancement level in the first BWP according to the coverage enhancement level which needs to perform coverage enhancement.

[0241] In yet another example embodiment of the present disclosure, a terminal determines a terminal type of the terminal, determines a first BWP if the terminal is a second type terminal, and determines whether the second type terminal needs to be coverage enhanced. In one approach, in response to the second type terminal not needing to be coverage enhanced, a PRACH resource corresponding to the second type terminal not needing to be coverage enhanced is determined in the first BWP. In one approach, in response to the second type terminal needing to be coverage enhanced, a coverage enhancement level needed for the second type terminal to be coverage enhanced is determined, and a PRACH resource corresponding to the coverage enhancement level is determined in the first BWP based on the coverage enhancement level.

[0242] In the access resource determination method provided by the present disclosure, the first terminal type and the second terminal type needing to be coverage enhanced share one BWP, thereby reducing the configuration of different PRACH resources for the first terminal type needing to be coverage enhanced. Thus, the effects of reducing resource fragmentation and reducing resource waste are achieved.

[0243] In one implementation, the first BWP includes a plurality of PRACH resources for the first type terminal needing to be coverage enhanced, and the plurality of PRACH resources are determined based on a plurality of coverage enhancement levels. The plurality of coverage enhancement levels are a plurality of coverage enhancement levels for the first type terminal needing to be coverage enhanced.

[0244] The terminal type includes a first type terminal and a second type terminal. The first type terminal and the second type terminal are distinguished based on the capability of the terminal, and the capability of the first type terminal is greater than the capability of the second type terminal. The capability can be the transceiving capability of the terminal. The first type terminal can be a normal terminal, and the transceiving capability of the first type terminal is relatively good. The second type terminal can be a capability-reduced terminal, and the transceiving capability of the second type terminal is relatively poor.

[0245] In one implementation, the second type terminal is a terminal needing to be coverage enhanced. The first BWP includes a plurality of PRACH resources for the second type terminal needing to be coverage enhanced, and the plurality of PRACH resources are determined based on a plurality of coverage enhancement levels. The plurality of coverage enhancement levels are a plurality of coverage enhancement levels for the second type terminal needing to be coverage enhanced.

[0246] The plurality of PRACH resources and the plurality of coverage enhancement levels are in a one-to-one mapping relationship.

[0247] The above two implementations can be implemented separately or together.

[0248] In the access resource determination method provided in the present disclosure, the network device determines a plurality of coverage enhancement levels, and determines a plurality of PRACH resources based on the plurality of coverage enhancement levels. A one-to-one mapping relationship between the plurality of PRACH resources and the plurality of coverage enhancement levels is determined. Thus, the terminal can determine the accessed BWP according to the type of the terminal and the coverage enhancement level.

[0249] Figure 10 is a flowchart of an access resource allocation method according to an exemplary embodiment. As shown in Figure 10 , the access resource allocation method is applied to a terminal, and further includes the following steps.

The first BWP can also include PRACH resources for the first type terminal that does not need to be subjected to coverage enhancement. That is, the PRACH resources for the first type terminal that does not need to be subjected to coverage enhancement, the PRACH resources for the first type terminal that needs to be subjected to coverage enhancement, and the PRACH resources for the second type terminal are configured in the same BWP. The terminal determines the corresponding PRACH resources in the first BWP according to the type of the terminal or the coverage enhancement level that needs to be subjected to coverage enhancement.
