In some embodiments, the RA-RNTI formula may include one or more frequency domain resources for transmitting a preamble. In some embodiments, the time domain and frequency domain resources may be decoupled / separated to reduce / reduce / minimize / control / limit the scope of the RA-RNTI.

[0021] Method 1: RA-RNTI may indicate / specify / provide one or more time domain resources (e.g., t_id, s_id, and / or other time domain resources) for transmitting a preamble. A random access response (RAR) and / or downlink control information (DCI) may indicate / specify / provide one or more frequency domain resources (e.g., f_id, ul_carrier_id, and / or other frequency domain resources) for transmitting a preamble. The current subcarrier spacing (SCS) may maintain a relationship with the range of t_id. For example, if an SCS of 960kHz is used, the maximum value of t_id corresponds to 640. A wireless communication device (e.g., UE, terminal, or service node) may receive / acquire at least one indication and / or identifier corresponding to / associated with / related to a frequency domain resource. For example, a wireless communication device may receive / acquire f_id and / or ul_carrier_id.

[0022] ·Method 2: RA-RNTI may indicate / specify / provide one or more time domain resources for sending a preamble. RAR and / or DCI may indicate / specify / provide one or more frequency domain resources for sending a preamble. One or more time domain resources may include an index (t_RO_id) of a PRACH opportunity in the time domain. The time domain resources may use / adopt a random access channel (RACH) opportunity (RO) index in a system frame. The wireless communication device may receive / acquire at least one indication and / or identifier corresponding to a frequency domain resource. For example, the wireless communication device may receive / acquire f_id and / or ul_carrier_id. In some embodiments, 4 bits (or other number of bits) may indicate / specify one or more frequency domain resources.

[0023] ·Method 3: RA-RNTI may indicate / specify / provide one or more frequency domain resources for sending a preamble. RAR and / or DCI may indicate one or more time domain resources for sending a preamble. One or more time domain resources may indicate / provide / include the starting position of a symbol and / or the time slot for transmitting a preamble. The starting position of the symbol may include the index (s_id) of the first orthogonal frequency division multiplexing (OFDM) symbol of the physical random access channel (PRACH) opportunity.

[0025] According to certain embodiments of the RA-RNTI formula, the wireless communication device and / or node may calculate the RA-RNTI using the granularity of the time domain symbol in the frame. The value of the time domain symbol may change according to the value of the SCS. For example, the value of the time domain symbol may increase / increase with higher values ​​of the SCS (e.g., 1,920kHz or other frequencies). In certain specifications, each PRACH configuration index (e.g., the PRACH configuration index specified in Table 6.3.3.2-2 to Table 6.3.3.2-4 in Section 6.3.3.2 of TS 38.211) corresponds to a limited number of PRACH opportunities in the time domain.

[0026] In some embodiments, the RA-RNTI formula may remain unchanged / unchanged. The RA-RNTI may indicate / specify at least 80 (or 160) time slots according to a specific specification. In some embodiments, the extended / incremented / increased SCS may have a value that is a multiple of 120kHz. Thus, the extended SCS may result in a number of time slots that is a multiple of 80 or 160 time slots. The wireless communication device may specify / indicate the group of time slots to which the RNTI belongs (e.g., a group of 80 and / or 160 time slots). The wireless communication device may use RAR and / or DCI (or other messages) to specify the group of time slots. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] 1. Mobile communication technology and environment

[0040] Figure 1An example wireless communication network and / or system 100 is shown in which the techniques disclosed herein may be implemented according to an embodiment of the present disclosure. In the following discussion, the wireless communication network 100 may be any wireless network, such as a cellular network or a narrowband Internet of Things (NB-IoT) network, and is referred to herein as "network 100." Such an example network 100 includes a base station 102 (hereinafter referred to as "BS 102," also referred to as a wireless communication node) and a user equipment device 104 (hereinafter referred to as "UE 104," also referred to as a wireless communication device) that may communicate with each other via a communication link 110 (e.g., a wireless communication channel), and a cluster of cells 126, 130, 132, 134, 136, 138, and 140 covering a geographic area 101. In Figure 1 1, BS 102 and UE 104 are contained within respective geographic boundaries of cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating over its allocated bandwidth to provide adequate radio coverage to its intended users.

[0041] For example, BS 102 may operate on an allocated channel transmission bandwidth to provide adequate coverage to UE 104. BS 102 and UE 104 may communicate via downlink radio frames 118 and uplink radio frames 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In the present disclosure, BS 102 and UE 104 are described herein as non-limiting examples of "communication nodes," which may generally practice the methods disclosed herein. According to various embodiments of the present solution, such communication nodes may be capable of wireless and / or wired communications.

[0042] Figure 2 A block diagram of an example wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) according to some embodiments of the present solution is shown. The system 200 may include components and elements configured to support known or conventional operating features that do not require detailed description herein. In one illustrative embodiment, as described above, the system 200 may be used in applications such as Figure 1 The wireless communication environment 100 of the present invention may be used to communicate (eg, send and receive) data symbols in a wireless communication environment such as the wireless communication environment 100 of the present invention.

[0043] The system 200 generally includes a base station 202 (hereinafter referred to as "BS 202") and a user equipment device 204 (hereinafter referred to as "UE 204"). The BS 202 includes a BS (base station) transceiver module 210, a BS antenna 212, a BS processor module 214, a BS memory module 216, and a network communication module 218, each of which is coupled to and interconnected with each other via a data communication bus 220 as needed. The UE 204 includes a UE (user equipment) transceiver module 230, a UE antenna 232, a UE memory module 234, and a UE processor module 236, each of which is coupled to and interconnected with each other via a data communication bus 240 as needed. The BS 202 communicates with the UE 204 via a communication channel 250, which can be any wireless channel or other medium suitable for data transmission as described herein.

[0044] Those skilled in the art will appreciate that the system 200 may further include Figure 2 Any number of modules other than the modules shown. It will be appreciated by those skilled in the art that the various illustrative blocks, modules, circuits, and processing logic described in conjunction with the embodiments disclosed herein can be implemented in hardware, computer-readable software, firmware, or any actual combination thereof. In order to clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, various illustrative components, blocks, modules, circuits, and steps are typically described according to their functionality. Whether this functionality is implemented as hardware, firmware, or software depends on the specific application and the design constraints imposed on the entire system. A technician familiar with the concepts described herein can implement this functionality in an appropriate manner for each specific application, but this implementation decision should not be interpreted as limiting the scope of the present disclosure.

[0045] According to some embodiments, the UE transceiver 230 may be referred to herein as an "uplink" transceiver 230, which includes a radio frequency (RF) transmitter and an RF receiver, each of which includes circuits coupled to an antenna 232. A duplex switch (not shown) may alternatively couple the uplink transmitter or receiver to the uplink antenna in a time division duplex manner. Similarly, according to some embodiments, the BS transceiver 210 may be referred to herein as a "downlink" transceiver 210, which includes an RF transmitter and an RF receiver, each of which includes circuits coupled to an antenna 212. The downlink duplex switch may alternatively couple the downlink transmitter or receiver transmission to the downlink antenna 212 in a time division duplex manner. The operation of the two transceiver modules 210 and 230 may be coordinated in time so that the uplink receiver circuit is coupled to the uplink antenna 232 to receive transmissions over the wireless transmission link 250 while the downlink transmitter is coupled to the downlink antenna 212. Instead, the operation of the two transceivers 210 and 230 may be coordinated in time such that the downlink receiver coupled to the downlink antenna 212 receives transmissions over the wireless transmission link 250 at the same time as the uplink transmitter coupled to the uplink antenna 232. In some embodiments, there is tight time synchronization between changes in duplex direction with only minimal guard times.

[0046] The UE transceiver 230 and the base station transceiver 210 are configured to communicate via a wireless data communication link 250 and cooperate with an appropriately configured RF antenna arrangement 212 / 232 that can support a specific wireless communication protocol and modulation scheme. In some illustrative embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards such as Long Term Evolution (LTE) and emerging 5G standards. However, it should be understood that the present disclosure is not necessarily limited to specific standards and related protocols in application. Instead, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternative or additional wireless data communication protocols, including future standards or variations thereof.

[0047] According to various embodiments, for example, BS 202 may be an evolved Node B (eNB), a serving eNB, a target eNB, a femtocell or a microcell. In some embodiments, UE 204 may be embodied in various types of user equipment, such as a mobile phone, a smart phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, a wearable computing device, etc. Processor modules 214 and 236 may be implemented or realized with a general purpose processor, a content addressable memory, a digital signal processor, an application specific integrated circuit, a field programmable gate array, any suitable programmable logic device, a discrete gate or transistor logic, a discrete hardware component, or any combination thereof, intended to perform the functions described herein. In this manner, the processor may be implemented as a microprocessor, a controller, a microcontroller, a state machine, etc. The processor may also be implemented as a combination of computing devices, such as a combination of a digital signal processor and a microprocessor, a plurality of microprocessors, one or more microprocessors combined with a digital signal processor core, or any other such configuration.

[0048] In addition, the steps of the methods or algorithms described in conjunction with the embodiments disclosed herein may be directly embodied in hardware, firmware, software modules executed by the processor modules 214 and 236, respectively, or any practical combination thereof. The memory modules 216 and 234 may be implemented as RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, removable disk, CD-ROM, or any other form of storage medium known in the art. In this regard, the memory modules 216 and 234 may be coupled to the processor modules 210 and 230, respectively, so that the processor modules 210 and 230 can read information from the memory modules 216 and 234 and write information to the memory modules 216 and 234, respectively. The memory modules 216 and 234 may also be integrated into their respective processor modules 210 and 230. In some embodiments, the memory modules 216 and 234 may each include a cache memory for storing temporary variables or other intermediate information during the execution of instructions to be executed by the processor modules 210 and 230, respectively. Memory modules 216 and 234 may also include non-volatile memory for storing instructions executed by processor modules 210 and 230, respectively.

[0049] The network communication module 218 generally represents the hardware, software, firmware, processing logic and / or other components of the base station 102, which enables bidirectional communication between the base station transceiver 210 and other network components and communication nodes configured to communicate with the base station 202. For example, the network communication module 218 can be configured to support Internet or WiMAX services. In a typical deployment, the network communication module 218 provides an 802.3 Ethernet interface without any limitation, so that the base station transceiver 210 can communicate with a conventional Ethernet-based computer network. In this way, the network communication module 218 may include a physical interface (e.g., a mobile switching center (MSC)) for connecting to a computer network. As used herein with respect to a specified operation or function, the term "configured for", "configured to" and its variations indicate a device, component, circuit, structure, machine, signal, etc. that is physically constructed, programmed, formatted, and / or arranged to perform a specified operation or function.

[0050] The Open Systems Interconnection (OSI) model (referred to herein as the "Open Systems Interconnection Model") is a concept and logical layout that defines network communications used by systems (e.g., wireless communication devices, wireless communication nodes) that disclose interconnection and communication with other systems. The model is divided into seven subcomponents or layers, each of which represents a conceptual set of services provided to its upper and lower layers. The OSI model also defines a logical network and effectively describes computer packet transmission by using different layer protocols. The OSI model may also be referred to as a seven-layer OSI model or a seven-layer model. In some embodiments, the first layer may be a physical layer. In some embodiments, the second layer may be a media access control (MAC) layer. In some embodiments, the third layer may be a radio link control (RLC) layer. In some embodiments, the fourth layer may be a packet data convergence protocol (PDCP) layer. In some embodiments, the fifth layer may be a radio resource control (RRC) layer. In some embodiments, the sixth layer may be a non-access stratum (NAS) layer or an Internet Protocol (IP) layer, and the seventh layer is other layers.

[0052] In a particular specification, a random access radio network temporary identifier (RA-RNTI) may be associated with a physical random access channel (PRACH) opportunity. The PRACH opportunity corresponds to a PRACH opportunity in which a random access preamble is transmitted / sent / broadcasted. A wireless communication device (e.g., UE, terminal, or serving node) and / or a wireless communication node (e.g., ground terminal, base station, gNB, eNB, or serving node) may derive / calculate / determine the RA-RNTI using the following formula:

[0053] RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id

[0054] s_id may correspond to / reference the index of the first orthogonal frequency division multiplexing (OFDM) symbol of the PRACH opportunity. s_id may have a value greater than or equal to 0 and less than 14. t_id may correspond to / reference the index of the first time slot of the PRACH opportunity in the system frame. t_id may have a value greater than or equal to 0 and less than 80. The value of the parameter μ (e.g., specified in Section 5.3.2 of TS 38.211 [8]) may indicate / affect / determine the subcarrier spacing. The subcarrier spacing may determine / indicate / specify the value of t_id. f_id may correspond to / reference the index of the PRACH opportunity in the frequency domain. f_id may have a value greater than or equal to 0 and less than 8. ul_carrier_id may correspond to / reference the uplink (UL) carrier used for random access preamble transmission. For a normal uplink (NUL) carrier, ul_carrier_id may have a value of 0. For a supplementary uplink (SUL) carrier, ul_carrier_id may have a value of 1.

[0055] The value of the subcarrier spacing (SCS) may affect / determine the range of t_id. In the system frame, when the value of SCS is 120kHz, the maximum value of t_id corresponds to 79. As shown in the RA-RNTI formula, the value of RA-RNTI can be a function of t_id. For example, if the value of t_id is 79 (e.g., the value of SCS is 120kHz), the maximum value of RA-RNTI corresponds to 17,920 (e.g., according to the RA-RNTI formula). When the value of SCS is 480kHz, the maximum value of t_id corresponds to 319. Therefore, the maximum value of RA-RNTI (e.g., the value of SCS is 480kHz) corresponds to 71,680 (e.g., the value of t_id is 319). In some embodiments, the range of RNTI may be restricted / limited / defined to a value greater than or equal to 0 and less than or equal to 65,535 (e.g., 0≤RNTI≤65,535). Therefore, if the SCS value is 480 kHz (eg, the t_id value is 319), the maximum value of the RA-RNTI exceeds 65,535 (eg, the upper limit). The systems and methods proposed herein include a new method for determining (or limiting) RNTI values.

[0056] A. Embodiment 1: RNTI represents time domain resources, and DCI or RAR represents frequency domain resources

[0057] In some specifications, the RA-RNTI may be associated / correlated with a PRACH opportunity. The PRACH opportunity corresponds to the PRACH opportunity at which the random access preamble is transmitted. The wireless communication device and / or wireless communication node may deduce / calculate / determine the RA-RNTI using the following formula:

[0058] RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id

[0059] The RA-RNTI formula may include / contain one or more time domain resources (e.g., one or more parameters associated with one or more time domain resources) for sending the preamble (e.g., s_id, t_id, and / or other time domain resource parameters). The RA-RNTI formula may include / contain one or more frequency domain resources (e.g., one or more parameters associated with one or more frequency domain resources) for sending the preamble (e.g., f_id, ul_carrier_id, and / or other frequency domain resource parameters). One or more time domain resources and frequency domain resources may be decoupled / separated to reduce / reduce / minimize the range of RA-RNTI. In some embodiments, the formula for providing / indicating / specifying the value of RA-RNTI may include one or more time domain resources. The formula for providing / indicating / specifying the RA-RNTI value may not include (e.g., not involving / taking into account) one or more frequency domain resources and / or their associated parameters. The wireless communication network may indicate / provide the frequency domain resources (or their associated parameters) to the wireless communication device. The wireless communication network may use DCI and / or RAR (or other types of signaling and / or messages) to indicate parameters associated with frequency domain resources.

[0060] In some embodiments, the RA-RNTI may be a function of parameters associated or corresponding to one or more time domain resources (e.g., s_id, t_id, and / or other parameters associated with the time domain resources) for sending the preamble (e.g., the RA-RNTI may not include parameters associated with the frequency domain resources). Therefore, the wireless communication device and / or the wireless communication node may use the following formula to deduce / calculate / determine the RA-RNTI:

[0061] RA-RNTI = 1 + s_id + 14 × t_id

[0062] According to the previous formula, if the value of SCS is 1,920 kHz, the range of t_id is between 0 and 1,279 (eg, 0≤t_id≤1,279). Therefore, the maximum value of RA-RNTI corresponds to 17,920, and thus does not exceed the upper limit (eg, 65,535).

[0063] A wireless communication node may indicate / provide one or more frequency domain resources (e.g., f_id, ul_carrier_id, and / or other frequency domain resources) for sending a preamble to a wireless communication device. A wireless communication node may use RAR and / or DCI to indicate one or more frequency domain resources. In some specifications, f_id may have a maximum value of 7. Therefore, at least 3 bits (or other number of bits) may indicate f_id. In some embodiments, at least 2 uplink (UL) carriers may be configured for a UL carrier, and therefore, at least 1 bit (or other number of bits) may indicate ul_carrier_id. Therefore, at least 4 bits (e.g., 3 bits of f_id and / or 1 bit of ul_carrier_id) may indicate / specify one or more frequency domain resources.

[0064] For the two-step random access procedure, the message B (MSGB) RNTI (MSGB-RNTI) may be associated with a PRACH opportunity. The PRACH opportunity corresponds to the PRACH opportunity in which the random access preamble is sent. The wireless communication device and / or wireless communication node may deduce / calculate / determine the MSGB-RNTI using the following formula:

[0065] MSGB-RNTI=1+s id +14×t id +14×80×f id +14×80×8×ul_carrier_id+14×80×8×2

[0066] In some embodiments, the MSGB-RNTI may be a function of one or more parameters associated with one or more time domain resources (e.g., s_id, t_id, and / or other time domain resource parameters) for transmitting the preamble (e.g., the MSGB-RNTI may not include frequency domain resource parameters). Therefore, the wireless communication device and / or the wireless communication node may deduce / calculate / determine the MSGB-RNTI using the following formula:

[0067] MSGB-RNTI=1+s_id+14×t_id+14×the maximum value of t-id

[0068] (the maximum value of t_id: the maximum value of t_id)

[0069] The value of SCS may determine / affect the maximum value of t_id. If the value of SCS is 1,920 kHz, the maximum value of MSGB-RNTI corresponds to 35,840 (or other number). At least 4 bits (e.g., 3 bits of f_id and / or 1 bit of ul_carrier_id) may indicate / specify one or more frequency domain resources (e.g., similar to a four-step random access channel (RACH)).

[0070] I. Wireless communication node side

[0071] In some embodiments, at least 1 bit may indicate / specify the ul_carrier_id for receiving / obtaining the preamble. At least 3 bits may indicate / provide the frequency domain resources for receiving the preamble. Thus, the wireless communication node may send / provide / indicate at least 4 bits to the wireless communication device. The wireless communication node may use DCI and / or RAR to provide at least 4 bits.

Multiple conditions may include that the cyclic redundancy check (CRC) of the DCI format is scrambled by the RA-RNTI. The DCI and / or RAR may indicate / specify one or more frequency domain resources and / or UL carriers. Multiple conditions may include that the indicated frequency domain resources correspond to the frequency domain resources on which the wireless communication device sends the PRACH. Multiple conditions may include that the indicated UL carrier corresponds to the UL carrier on which the wireless communication device sends the PRACH. At least one of the plurality of conditions may include / be that the random access preamble identifier in the media access control (MAC) protocol data unit (PDU) corresponds to the transmitted preamble index.

At least one condition in the first set of conditions may be / include that the CRC of the DCI format is scrambled by the MSGB-RNTI. The DCI and / or RAR may indicate / specify one or more frequency domain resources and / or UL carriers.

At least one condition in the first set of conditions may be / include that the indicated UL carrier corresponds to the UL carrier on which the wireless communication device transmits the PRACH. In some embodiments, the MSGB (or MsgB) may include a fallbackRAR MAC sub-PDU (or other data unit or message).

At least one condition in the first set of conditions may be / include that the random access preamble identifier in the MAC PDU corresponds to the transmitted preamble index (e.g., if included in the MAC PDU).

[0077] In some embodiments, when one or more conditions in the second set of conditions are met, the random access response may indicate successful reception. The wireless communication device may detect / determine / identify a DCI format (e.g., DCI format 1_0 or other types and / or formats of DCI). At least one condition in the second set of conditions may be / include that the CRC of the DCI format is scrambled by the MSGB-RNTI. The DCI and / or RAR may indicate / specify one or more frequency domain resources and / or UL carriers. At least one condition in the second set of conditions may be / include that the indicated frequency domain resources correspond to the frequency domain resources on which the wireless communication device sends the PRACH.

[0078] B. Embodiment 2: RNTI represents time domain resources, DCI or RAR represents frequency domain resources, and RO index is used as t_id

[0079] The operations and functions of the RA-RNTI may include any one or more components, operations, and / or features described in the RA-RNTI description of Part A (Example 1). A wireless communication device and / or a wireless communication node may deduce / calculate / determine the RA-RNTI using the following formula:

[0080] RA-RNTI = 1 + s_id + 14×t_id + 14×80×f_id + 14×80×8×ul_carrier_id

[0081] In some embodiments, the RA-RNTI may be a function of one or more parameters associated with one or more time-domain resources (e.g., s_id, t_id, and / or other time-domain resources) for transmitting a preamble (e.g., a preamble). (For example, the RA-RNTI may not include parameters related to frequency-domain resources). The one or more parameters associated with the one or more time-domain resources may include / contain the RACH opportunity (RO) index (RO_index) in the system frame. The RA-RNTI formula may be a function of the RO_index (or other time-domain index). Therefore, a wireless communication device and / or a wireless communication node may deduce / calculate / determine the RA-RNTI using the following formula:

[0082] RA-RNTI = 1 + t_RO_id

[0083] t_RO_id may indicate / provide / specify / correspond to the index of the PRACH opportunity in the domain (e.g., in the system frame). t_RO_id may have a value greater than or equal to 0 and less than t_RO_total (e.g., 0 ≤ t_RO_id ≤ t_RO_total). t_RO_total may indicate / provide / specify / correspond to the total number of PRACH opportunities in the time domain in the system frame. t_RO_total may have a value greater than 0 and less than or equal to 70 (e.g., 0 < t_RO_total ≤ 70). t_RO_id and / or t_RO_total may be determined based on the PRACH configuration index (e.g., specified in Tables 6.3.3.2-2 to 6.3.3.2-4 in Section 6.3.3.2 of TS 38.211).

[0084] A wireless communication node may indicate / provide one or more parameters (e.g., f_id, ul_carrier_id, and / or other frequency domain resource parameters) associated with one or more frequency domain resources for sending a preamble to a wireless communication device. A wireless communication node may use RAR and / or DCI to indicate one or more parameters associated with one or more frequency domain resources. In some specifications, the maximum value of f_id is 7 (or other number). Therefore, at least 3 bits (or other number of bits) may indicate f_id. In some embodiments, at least 2 uplink (UL) carriers may be configured for a UL carrier, and therefore, at least 1 bit (or other number of bits) may indicate ul_carrier_id. Therefore, at least 4 bits (e.g., 3 bits of f_id and / or 1 bit of ul_carrier_id) may indicate / specify one or more frequency domain resources.

[0085] For the two-step random access procedure, the MSGB-RNTI may be associated with a PRACH opportunity. The PRACH opportunity corresponds to the PRACH opportunity at which the random access preamble is transmitted. The wireless communication device and / or wireless communication node may deduce / calculate / determine the MSGB-RNTI using the following formula:

[0086] MSGB-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+14×80×8×2

[0087] In some embodiments, the MSGB-RNTI may be a function of one or more parameters (e.g., s_id, t_id, t_RO_id and / or other time domain resource parameters) associated with one or more time domain resources for transmitting the preamble (e.g., the MSGB-RNTI may not include frequency domain resource parameters). Therefore, the wireless communication device and / or the wireless communication node may use the following formula to deduce / calculate / determine the MSGB-RNTI:

[0088] MSGB-RNTI=1+t_RO_id+t_RO_total

[0089] At least 4 bits (eg, 3 bits of f_id and / or 1 bit of ul_carrier_id) may indicate / specify one or more frequency domain resources.

[0090] In this embodiment (Embodiment 2), the operations and functions of the wireless communication node may be performed by any one or more components and / or operations described in conjunction with subsection I (wireless communication node side) of section A (Embodiment 1). In this embodiment (Embodiment 2), the operations and functions of the wireless communication device may be performed by any one or more components and / or operations described in conjunction with subsection II (wireless communication device side) of section A (Embodiment 1).

[0091] C. Embodiment 3: RNTI represents frequency domain resources, and DCI or RAR represents time domain resources

[0092] In some implementations, the RA-RNTI may be associated / correlated with a PRACH opportunity. The PRACH opportunity corresponds to a PRACH opportunity at which a random access preamble is transmitted. The wireless communication device and / or wireless communication node may deduce / calculate / determine the RA-RNTI using the following formula:

[0093] RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id

[0094] The RA-RNTI formula may include / contain one or more parameters associated with one or more time domain resources for sending the preamble (e.g., s_id, t_id, and / or other time domain resource parameters). The RA-RNTI formula may include / contain one or more parameters associated with one or more frequency domain resources for sending the preamble (e.g., f_id, ul_carrier_id, and / or other frequency domain resource parameters). One or more time domain resources and frequency domain resources (and / or their associated parameters) may be decoupled / separated to reduce / reduce / minimize the range of RA-RNTI. In some embodiments, the formula for providing / indicating / specifying the value of RA-RNTI may include one or more parameters associated with one or more frequency domain resources. The formula for providing / indicating / specifying the RA-RNTI value may not include parameters associated with one or more time domain resources. The wireless communication network may indicate / provide parameters associated with time domain resources to the wireless communication device. The wireless communication network may use DCI and / or RAR (or other types of signaling and / or messages) to indicate parameters associated with time domain resources.

[0095] In some embodiments, the RA-RNTI may be a function of parameters associated with one or more frequency domain resources (e.g., f_id, ul_carrier_id, and / or other frequency domain resources) for transmitting the preamble (e.g., the RA-RNTI may not include parameters related to time domain resources). Therefore, the wireless communication device and / or the wireless communication node may use the following formula to deduce / calculate / determine the RA-RNTI:

[0096] RA-RNTI=1+f_id+8×ul_carrier_id

[0097] The above formula is not related to the value of SCS (eg, the formula does not include t_id). Therefore, the value range of RA-RNTI can be 0 to 15 (or other number).

[0098] In some embodiments, a wireless communication node may indicate / provide / specify parameters associated with one or more time domain resources (e.g., the starting position of a symbol, the time slot in which a preamble is sent, and / or other time domain resources) to a wireless communication device. A wireless communication node may use DCI and / or RAR to indicate parameters associated with one or more time domain resources. At least 4 bits (or other number of bits) may indicate / provide information of a symbol (e.g., the starting position of a symbol). If the value of SCS is 1,920kHz, at least 11 bits (or other number of bits) may indicate information of a time slot (e.g., the time slot in which a preamble is sent). Therefore, if the value of SCS is ,920kHz, at least 15 bits may be used to indicate parameters associated with one or more time domain resources.

[0099] For the two-step random access procedure, the MSGB-RNTI may be associated with a PRACH opportunity. The PRACH opportunity corresponds to the PRACH opportunity at which the random access preamble is transmitted. The wireless communication device and / or wireless communication node may deduce / calculate / determine the MSGB-RNTI using the following formula:

[0100] MSGB-RNTI=1+s-id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+14×80×8×2

[0101] In some embodiments, the MSGB-RNTI may be a parameter (e.g., f_id, ul_carrier_id, and / or other frequency domain resource parameters) of one or more frequency domain resources for sending the preamble or a function of parameters associated with one or more frequency resources for sending the preamble (e.g., f_id, ul_carrier_id, and / or other frequency domain resource parameters) (e.g., the MSGB-RNTI may not include time domain resources). Therefore, the wireless communication device and / or the wireless communication node may use the following formula to deduce / calculate / determine the MSGB-RNTI:

[0102] MSGB-RNTI=1+f_id+8×ul_carrier_id+8×2

[0103] At least 15 bits (e.g., 11 bits of slot information and / or 4 bits of symbol information) may indicate / specify parameters associated with one or more time domain resources (e.g., similar to a four-step random access procedure, provided that the SCS value is 1,920 kHz).

[0104] I. Wireless communication node side

[0105] In some embodiments, the wireless communication node may indicate / provide one or more time domain resources (e.g., the position of the symbol, the time slot in which the preamble has been received, and / or other time domain resources) to the wireless communication node. The wireless communication node may use DCI and / or RAR to indicate parameters associated with the time domain resources. For example, if the value of SCS is 1,920kHz, at least 4 bits may indicate the position of the symbol. In the same example, at least 9 bits may indicate the time slot in which the preamble has been received. Therefore, the wireless communication node may use DCI and / or RAR to provide at least 13 bits to the wireless communication device.

[0106] II. Wireless communication equipment side

[0107] For the four-step random access process

[0108] In some embodiments, when one or more of the multiple conditions are met, the random access response may indicate successful reception.

[0114] RA-RNTI=1+s_id+14×t_id+i4×80×f_id+l4×80×8×ul_carrier_id

[0115] In some embodiments, the RA-RNTI may be a function of parameters associated with one or more frequency domain resources for transmitting the preamble (e.g., f_id, ul_carrier_id, and / or other frequency domain resource parameters) (e.g., the RA-RNTI may not include time domain resource parameters). Therefore, the wireless communication device and / or the wireless communication node may use the following formula to deduce / calculate / determine the RA-RNTI:

[0116] RA-RNTI=1+f_id+8×ul_carrier_id

[0117] The above formula may be unrelated to / independent of the value of SCS (eg, the formula does not include t_id). Therefore, the value range of RA-RNTI may be 0 to 15 (or other number).

[0118] The parameters associated with one or more time domain resources may include / contain t_RO_id.

[0131] E. Embodiment 5: PRACH Occasion Index t_RO_id replaces the time domain symbol index and time slot index

[0132] In some embodiments, the formula for generating / determining / calculating RNTI may be modified / changed to reduce / limit / maintain the range of possible values ​​of RNTI. Modifying the formula may reduce signaling overhead (e.g., signaling overhead for time domain and / or frequency domain indication). The wireless communication device and / or wireless communication node may use the following formula to deduce / calculate / determine RA-RNTI:

[0133] RA-RNTI=1+t_RO_id+t_RO_total×f_id+t_RO_total×8×ul_carrier_id

[0134] The wireless communication device and / or wireless communication node may deduce / calculate / determine the MSGB-RNTI using the following formula:

[0135] MSGB-RNTI=1+t_RO_id+t_RO_total×f_id+t_RO_total×8×ul_carrier_id+t_RO_total×8×2

[0136] The operations and functions of t_RO_id may include any one or more components, operations and / or characteristics described in conjunction with t_RO_id of Part B (Embodiment 2). The operations and functions of t_RO_total may include any one or more components, operations and / or characteristics described in conjunction with t_RO_total of Part B (Embodiment 2). f_id may correspond to / reference the timing index of the PRACH in the frequency domain (e.g., 0≤f_id<8). ul_carrier_id may correspond to / reference the UL carrier used for random access preamble transmission (e.g., 0 for NUL carrier and / or 1 for SUL carrier).

[0137] According to certain configurations (e.g., the PRACH configuration specified in TS 38.211), the maximum value of t_RO_total corresponds to 70. Therefore, the maximum value of RA-RNTI corresponds to 1,120 (e.g., 7×8×2). The maximum value of MSGB-RNTI corresponds to 2,240 (e.g., 7×8×2×2). If the maximum SCS is increased / extended / incremented to 1,920 kHz, the maximum value of RA-RNTI corresponds to 17,920 (e.g., within the RNTI range (0, 65, 535)). If the maximum SCS is increased / extended / incremented to 1,920 kHz, the maximum value of MSGB-RNTI corresponds to 35,840 (e.g., within the RNTI range (0, 65, 535)).

[0138] Now refer to the figure for reference Figure 3, shows a table 300 for random access configuration for frequency range 2 (FR2) and / or unpaired spectrum. In some embodiments, the PRACH configuration index can be configured using table 300. For example, the PRACH configuration index corresponds to a value of 26 (or other number). The wireless communication device can select / identify a PRACH opportunity located in symbols 4-5 within slot 31 in the time domain. According to table 300, there are 7 time slots containing PRACH opportunities before the time slot containing the target PRACH opportunity (e.g., slots 3, 7, 11, 15, 19, 23, and 27). In some embodiments, there are 2 PRACH opportunities before symbol 4 in slot 31. Therefore, t_RO_id can be deduced / calculated as 7×6+2=44. t_RO_id can be the number of time slots before the time slot containing the target PRACH opportunity, the number of time domain PRACH opportunities within the PRACH time slot, or the number of time slots before the time slot containing the target PRACH opportunity. and / or a function of the number of PRACH opportunities preceding the symbol containing the target PRACH opportunity. t_RO_total may be derived / calculated as 10×6=60.

[0139] F. Embodiment 6: DCI or RAR indicates time slot

[0140] In some specifications, the RA-RNTI may be associated / correlated with a PRACH opportunity. The PRACH opportunity corresponds to the PRACH opportunity at which the random access preamble is transmitted. The wireless communication device and / or wireless communication node may deduce / calculate / determine the RA-RNTI using the following formula:

[0141] RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id

[0142] s_id may correspond to / reference the index of the first OFDM symbol of a PRACH opportunity (e.g., 0≤s_id<14). When the subcarrier spacing is less than or equal to 120 kHz (or other frequencies), t_id may correspond to / reference the index of the first time slot of a PRACH opportunity in a system frame (e.g., 0≤t_id<80). In some embodiments, when the subcarrier spacing is greater than 120 kHz (or other frequencies), t_id may correspond to / reference the index of the first time slot of a PRACH opportunity in a group of 80 time slots (or 160 time slots). The value of the parameter μ (e.g., as specified in Section 5.3.2 of TS 38.211 [8]) may indicate / affect / determine the subcarrier spacing. The subcarrier spacing may determine / indicate / specify the value of t_id. f_id may correspond to / reference the index of a PRACH opportunity in the frequency domain (e.g., 0≤f_id<8). ul_carrier_id may correspond / reference the UL carrier used for random access preamble transmission (eg, 0 for NUL carrier and / or 1 for SUL carrier).

[0143] Reference now Figure 4 , a representation 400 of an example system frame for transmitting an RNTI is shown. In some embodiments, the value of SCS corresponds to 120kHz (or other frequency). Under certain standards / specifications, the value 120kHz corresponds to the maximum value of SCS. If the value of SCS is 120kHz, the number of time slots corresponds to 80 (or other number). The number of time slots (e.g., 80 time slots or other number) may indicate / provide / specify the level of granularity of the system frame. The number of time slots corresponds to one cycle / interval in a plurality of cycles / intervals. In some embodiments, the value of SCS may be greater than 120kHz. The value of SCS corresponds to a multiple of 120kHz. For example, the value of SCS corresponds to 240kHz. If the value of SCS is 240kHz (e.g., 120×2), the total number of time slots in the system frame corresponds to 160 time slots (e.g., 80×2). The total number of time slots corresponds to a multiple of 80 time slots. In another example, the value of SCS corresponds to 1,920kHz. If the value of SCS is 1,920 kHz (e.g., 120×16), the total number of time slots in the system frame corresponds to 1,280 time slots (e.g., 80×16). Figure 5 As shown, if the value of SCS is 480kHz (e.g., 120×4), the total number of time slots in the system frame may correspond to 320 time slots (e.g., 80×4). The granularity level of the system frame corresponds to 80 time slots (e.g., the first 80 time slots, the second 80 time slots, the third 80 time slots, and the fourth 80 time slots).

[0144] In some embodiments, the wireless communication device may indicate / specify the time slot group to which the RNTI belongs (e.g., the first 80 time slots, the second 80 time slots, and / or other time slot groups). If the value of the SCS is 480kHz and there are 4 groups of 80 time slots, at least 2 bits (or other number of bits) may indicate the time slot group to which the RNTI belongs. The wireless communication node may use at least 2 bits to indicate the time slot group via DCI and / or RAR. If the value of the SCS is 1,920kHz and there are 16 groups of 80 time slots, at least 4 bits (or other number of bits) may indicate the time slot group to which the RNTI belongs.

[0154] The operations and functions of RA-RNTI may include any one or more components, operations and / or characteristics described in conjunction with Part F (Embodiment 6) RA-RNTI. The wireless communication device and / or wireless communication node may use the following formula to deduce / calculate / determine RA-RNTI:

[0155] RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id

[0156] If the value of SCS is 120kHz, the maximum value of t_id corresponds to 79. If the value of SCS is 120kHz, the maximum value of RA-RNTI corresponds to 17,920. If the value of SCS is 240kHz, the maximum value of t_id corresponds to 159. If the value of SCS is 240kHz, the maximum value of RA-RNTI corresponds to 35840. Therefore, if the value of SCS is 240kHz, the maximum value of RA-RNTI (e.g., 35,840) is within the range of RA-RNTI (e.g., 0≤RA-RNTI<65,535). In some embodiments, t_id can be increased / incremented / extended to a value of 160 (or other number).

[0157] If t_id is extended to 160, the number of time slots in the group corresponds to 160 time slots (e.g., the granularity level corresponds to 160 time slots). For an SCS value of 480 kHz, the total number of time slots corresponds to 320 time slots (e.g., 160×2). In another example, for an SCS value of 1,920 kHz, the total number of time slots corresponds to 1,280 time slots (e.g., 160×8). In this example, at least 3 bits (or other number of bits) may indicate / specify a group of 160 time slots to which the RA-RNTI belongs. The DCI and / or RAR may indicate / specify a group of 160 time slots to which the RA-RNTI belongs.
