Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular, to a method and apparatus for processing random access parameters, and a storage medium. Background Art

[0002] With the continuous development of Internet of Things (IoT) services, such as the popularization of services like video surveillance, smart home, wearable devices, and industrial sensing monitoring, these services usually require a rate of dozens to 100 M, and at the same time, have relatively high requirements for latency. Therefore, the MTC and NB-IoT technologies in LTE are difficult to meet the requirements. Based on this situation, many companies have proposed to design a new type of terminal in 5G NR (New Radio) to cover the requirements of such mid-range IoT devices. In the current 3GPP standardization, the New Radio Lite (NR lite) system has introduced a new type of terminal whose transmission latency, rate requirements, and terminal cost are all between those of narrowband terminals and NR terminals. This new type of terminal is called Redcap UE (Reduced Capability User Equipment) or simply NR-lite.

[0003] In known technical solutions, as long as the PRACH (Physical Random Access Channel) resources used by terminals performing random access have the same time and the same frequency, then the random access responses of these terminals will be in the same PDSCH (Physical Downlink Shared Channel) and be scheduled by the same PDCCH (RAR PDCCH). In the known NR, the search space for carrying the RAR (Random Access Response) scheduling is called the type-1 PDCCH CSS (Common Search Space), and the carried PDCCH is scrambled with CRC by the RA-RNTI (Random Access-Radio Network Temporary Identity). The current RA-RNTI is determined according to the following rule:

[0004] RA-RNTI = 1 + s_id + 14×t_id + 14×80×f_id + 14×80×8×ul_carrier_id,

[0005] Where: s_id is the starting symbol index of the PRACH, 0 ≤ s_id < 14; t_id is the starting time slot index of the PRACH within the system frame, 0 ≤ t_id < 80; f_id is the frequency domain position index of the PRACH, 0 ≤ f_id < 8; and ul_carrier_id is the uplink carrier type for transmitting MSG1 (the message for transmitting the Preamble sequence), where 0 represents the normal uplink NUL carrier and 1 represents the supplementary uplink SUL carrier).

[0006] Low-capability terminals and normal UEs (normal terminals) access the network through the same SSB (Synchronization Signal Block) and share CORESET#0 (Control Resource Set#0). Their RAR PDCCHs may all be transmitted in CORESET#0. This may result in two RAR PDCCHs with the same RA-RNTI in CORESET#0, leading to conflicts. Summary of the Invention

[0147] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0148] The access method provided by an embodiment of the present disclosure can be applied to Figure 1 the wireless communication system shown in Figure 1 As shown, the wireless communication system 100 includes a network device 110 and a terminal 120. Information is transmitted and received between the network device 110 and the terminal 120 via wireless resources.

[0149] It can be understood that Figure 1 the wireless communication system shown in Figure 1 is only for illustrative purposes, and other network devices may also be included in the wireless communication system, such as a core network device, a wireless relay device, and a wireless backhaul device, etc., which are not drawn in

[0150] Furthermore, it can be understood that the wireless communication system of the embodiment of the present disclosure is a network that provides wireless communication functions. The wireless communication system can adopt 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 FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance (CSMA / CA). According to factors such as the capacity, rate, and latency of different networks, the network can be divided into 2G (Generation) network, 3G network, 4G network, or future evolved network, such as 5G network, and 5G network can also be referred to as 5G New Radio. For the convenience of description, the wireless communication network is sometimes simply referred to as the network in the present disclosure.

[0151] Furthermore, the network device involved in the present disclosure may also be referred to as a radio access network device. The radio access network device may be: a base station, an evolved NodeB (eNodeB or 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), or a transmission and reception point (TRP), etc. It may also be a base station (gNodeB or gNB) in an NR system, or it may also be a component or a part of a device that constitutes a base station. It should be understood that in the embodiments of the present disclosure, the specific technologies and specific device forms adopted by the network device are not limited. In the present disclosure, the network device can provide communication coverage for a specific geographical area and can communicate with terminals located within the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device may also be an in-vehicle device.

[0152] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. It is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with wireless connection capabilities, an in-vehicle device, etc. Currently, some examples of terminals are: smartphones, pocket personal computers (PPCs), palmtop computers, personal digital assistants (PDAs), laptop computers, tablet computers, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the terminal.

[0153] The terminal involved in the embodiments of the present disclosure can be understood as a new type of terminal designed in 5G NR: Reduced capability UE, or simply referred to as NR-lite. In the embodiments of the present disclosure, this new terminal is referred to as 5G NR-lite.

[0154] Similar to Internet of Thing (IoT) devices in Long Term Evolution (LTE), 5G NR-lite usually needs to meet the following requirements: low cost, low complexity; a certain degree of coverage enhancement; and power saving.

[0155] Since the current NR system is designed for high-end terminals such as high rate and low latency, the current design cannot meet the above requirements of NR-lite. Therefore, it is necessary to transform the current NR system to meet the requirements of NR-lite. For example, to meet the requirements of low cost and low complexity, the radio frequency (RF) bandwidth of NR-IoT can be restricted, such as restricted to 5 MHz or 10 MHz, or the size of the buffer of NR-lite can be restricted, thereby restricting the size of each received transport block, etc. For power saving, the possible optimization direction is to simplify the communication process and reduce the number of times the NR-lite terminal detects the downlink control channel, etc.

[0156] Since the reception capabilities of low-capability terminals are different from those of normal NR terminals, the network may configure different initial UL BWPs (bandwidth parts) for low-capability terminals and normal terminals. There are various corresponding PRACH configurations on different initial UL BWPs.

[0157] Since the RA-RNTI is only related to the time-frequency number of the PRACH within each BWP, and since low-capability terminals and normal terminals access the network through the same SSB, and at this time they share CORESET#0, then their RAR PDCCHs may both be sent in CORESET#0. When low-capability terminals and normal terminals use the same RO (RACH Occasion, random access occasion) and send using the same numbered PRACH frequency resources in their respective initial UL BWPs, then there may be two RAR PDCCHs with the same RA-RNTI in CORESET#0, resulting in a conflict situation.

[0158] The embodiments of the present disclosure provide a random access parameter processing method, which is applied to a first type of user terminal UE. Figure 2 It is a flowchart of a random access parameter processing method shown according to an exemplary embodiment. Refer to Figure 2 As shown, the random access parameter processing method is applied to a first type of user terminal UE, including the following step S210.

[0159] In step S210, a first parameter for a first type of UE to perform random access is determined. The first parameter for the first type of UE to perform random access is not completely the same as or completely different from a second parameter for a second type of UE to perform random access; where the types of the first type of UE and the second type of UE are different.

[0160] According to the above step S210, the first type of UE determines its corresponding RA-RNTI. The above first parameter corresponds to the RA-RNTI of the first type of UE, and the second parameter corresponds to the RA-RNTI of the second type of UE. For example, the first type of UE is a Redcap UE, and the second type of UE is a normal NR UE.

[0161] In some embodiments of the present disclosure, the UE capability of the first type of UE is lower than the UE capability of the second type of UE. As described above, in the new radio simplified system, the first type of UE may be a Redcap UE, and the second type of UE may be a normal UE. The first type of UE and the second type of UE may be two types of UEs with different UE capabilities. It should be understood that in the embodiments of the present disclosure, the specific types of the first type of UE and the second type of UE are not limited. Hereinafter, taking the first type of UE as a Redcap UE and the second type of UE as a normal NR UE as an example, various exemplary embodiments of the present disclosure will be described.

The initial ULBWP corresponding to the first type of UE is different from the initial UL BWP corresponding to the second type of UE.

[0165] In some embodiments of the present disclosure, when SUL is not configured, the RA-RNTI corresponding to the first type of UE is determined only according to Z (frequency division multiplexing FDM parameter). Specifically, when supplementary uplink SUL is not configured, the method for determining the RA-RNTI includes: determining the RA-RNTI of the Redcap UE through the formula RA-RNTI = 1 + s_id + 14×t_id + 14×80×f_id + 14×80×Z.

[0176] In some embodiments of the present disclosure, determine the RA-RNTI corresponding to the first type of UE according to the SUL and Z. Specifically, the method for determining the RA-RNTI includes: determining the RA-RNTI of the Redcap user equipment through the formula RA-RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × Z + 14 × 80 × 8,

[0177] Wherein:

[0178] s_id is the starting symbol index of the PRACH, 0 ≤ s_id < 14;

[0179] t_id is the starting time slot index of the PRACH within the system frame, 0 ≤ t_id < 80;
