(1. Mobile Communication Technology and Environment)

[0031] FIG. 1 illustrates an example wireless communication network and / or system 100 in which techniques disclosed herein according to embodiments of the present disclosure may be implemented. 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 (NE-IoT) network, and is referred to herein as "network 100." Such an example network 100 includes a base station 102 (hereinafter also referred to as "BS 102," wireless communication node), user equipment devices 104 (hereinafter also referred to as "UE 104," wireless communication device), which may communicate with each other via communication links 110 (e.g., wireless communication channels), and clusters of cells 126, 130, 132, 134, 136, 138, and 140 overlaying a geographic area 101. In FIG. 1, the BS 102 and the UE 104 are included within the respective geographic boundaries of the cell 126. Each of the other cells 130, 132, 134, 136, 138, and 140 may include at least one base station operating in its allocated bandwidth to provide adequate wireless coverage to its intended users.

[0032] For example, the BS 102 may operate with an allocated channel transmission bandwidth to provide an adequate coverage area to the UE 104. The BS 102 and the UE 104 may communicate by a downlink radio frame 118 and an uplink radio frame 124, respectively. Each radio frame 118 / 124 may be further divided into subframes 120 / 127, which may include data symbols 122 / 128. In this disclosure, the BS 102 and the UE 104 are generally described herein as non-limiting examples of "communication nodes" that may practice the methods disclosed herein. Such communication nodes may be capable of wireless and / or wired communication according to various embodiments of the present solution.

[0033] 2 illustrates a block diagram of an exemplary wireless communication system 200 for transmitting and receiving wireless communication signals (e.g., OFDM / OFDMA signals) in accordance with some embodiments of the present solution. System 200 may include components and elements configured to support known or conventional operational features that need not be described in detail herein. In one illustrative embodiment, system 200 may be used to communicate (e.g., transmit and receive) data symbols in a wireless communication environment, such as wireless communication environment 100 of FIG. 1, as described above.

[0034] The system 200 generally includes a base station 202 (hereinafter "BS 202") and a user equipment device 204 (hereinafter "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 and interconnected with each other, as needed, via a data communication bus 220. 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 and interconnected with each other, as needed, via a data communication bus 240. The BS 202 communicates with the UE 204 via a communication channel 250, which may be any wireless channel or other medium suitable for the transmission of data as described herein.

[0035] As would be understood by a person skilled in the art, the system 200 may further include any number of modules other than those shown in FIG. 2. Those skilled in the art will appreciate that the various illustrative blocks, modules, circuits, and processing logic described in connection with the embodiments disclosed herein may be implemented in hardware, computer readable software, firmware, or any practical combination thereof. To clearly illustrate this interchangeability and compatibility of hardware, firmware, and software, the various illustrative components, blocks, modules, circuits, and steps are generally described in terms of their functionality. Whether such functionality is implemented as hardware, firmware, or software may depend on the particular application and design constraints imposed on the overall system. Those familiar with the concepts described herein may implement such functionality in a suitable manner for each particular application, but such implementation decisions should not be interpreted as limiting the scope of the present disclosure.

[0036] 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 with circuitry each 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-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 with circuitry each coupled to an antenna 212. A downlink duplex switch may alternatively couple the downlink transmitter or receiver to the downlink antenna 212 in a time-duplex manner. The operation of the two transceiver modules 210 and 230 is coordinated in time such that the downlink transmitter is coupled to the downlink antenna 212 at the same time that the uplink receiver circuitry is coupled to the uplink antenna 232 for reception of transmissions over the wireless transmission link 250. Conversely, the operation of the two transceivers 210 and 230 may be coordinated in time such that the uplink transmitter is coupled to the uplink antenna 232 at the same time that the downlink receiver is coupled to the downlink antenna 212 for reception of transmissions over the wireless transmission link 250. In some embodiments, there is close time synchronization with minimal guard time between changes in duplex direction.

[0037] The UE transceiver 230 and the base station transceiver 210 are configured to communicate over a wireless data communications link 250 and cooperate with a suitably configured RF antenna arrangement 212 / 232 that may support a particular wireless communications protocol and modulation scheme. In some demonstrative embodiments, the UE transceiver 210 and the base station transceiver 210 are configured to support industry standards, such as Long Term Evolution (LTE) and the emerging 5G standard. However, it should be understood that the present disclosure is not necessarily limited in application to a particular standard and associated protocol. Rather, the UE transceiver 230 and the base station transceiver 210 may be configured to support alternative or additional wireless data communications protocols, including future standards or variants thereof.

[0038] According to various embodiments, the BS 202 may be, for example, an evolved Node B (eNB), a serving eNB, a target eNB, a femto station, or a pico station. In some embodiments, the UE 204 may be embodied in various types of user devices, such as a mobile phone, a smartphone, a personal digital assistant (PDA), a tablet, a laptop computer, a wearable computing device, etc. The 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, discrete gate or transistor logic, discrete hardware components, or any combination thereof, designed to perform the functions described herein. Thus, the processor may be realized 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 digital signal processor and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a digital signal processor core, or any other such configuration.

[0039] Furthermore, the steps of the methods or algorithms described in connection with the embodiments disclosed herein may be embodied in hardware, firmware, software modules, or any practical combination thereof, executed directly by the processor modules 214 and 236, respectively. The memory modules 216 and 234 may be realized 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, such that the processor modules 210 and 230 may read information from and write information to the memory modules 216 and 234, respectively. The memory modules 216 and 234 may be integrated within their respective processor modules 210 and 230. In some embodiments, each of the memory modules 216 and 234 may include a cache memory for storing temporary variables or other intermediate information during execution of instructions executed by the processor modules 210 and 230, respectively. Each of the memory modules 216 and 234 may also include non-volatile memory for storing instructions for execution by the processor modules 210 and 230, respectively.

[0040] The network communications module 218 generally represents hardware, software, firmware, processing logic, and / or other components of the base station 202 that enable bidirectional communications 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 communications module 218 may be configured to support Internet or WiMAX traffic. In a typical deployment, without limitation, the network communications module 218 provides an 802.3 Ethernet interface so that the base station transceiver 210 may communicate with conventional Ethernet-based computer networks. As such, the network communications module 218 may include a physical interface for connection to a computer network (e.g., a Mobile Switching Center (MSC)). The terms “configured for,” “configured to,” and conjugations thereof, with respect to a specified operation or function, as used herein, refer to a device, component, circuit, structure, machine, signal, etc. that is physically constructed, programmed, formatted, and / or arranged to perform the specified operation or function.

[0041] The Open Systems Interconnection (OSI) model (referred to herein as the "Open Systems Interconnection Model") is a conceptual and logical layout that defines the network communications used by open systems (e.g., wireless communication devices, wireless communication nodes) to interconnect and communicate with other systems. The model is divided into seven subcomponents or layers, each of which represents a conceptual collection of services provided to the layers above and below it. The OSI model also defines logical networks, effectively describing computer packet transfers by using different layer protocols. The OSI model may also be referred to as the seven-layer OSI model or seven-layer model. In some embodiments, the first layer may be the physical layer. In some embodiments, the second layer may be the medium access control (MAC) layer. In some embodiments, the third layer may be the radio link control (RLC) layer. In some embodiments, the fourth layer may be the packet data convergence protocol (PDCP) layer. In some embodiments, the fifth layer may be the 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 may be another layer. 2. Systems and Methods for Combining PUSCH and PRACH Subcarrier Spacing

[0042] For high frequency communication, the channel bandwidth is usually wider than that in the fifth generation (5G) new radio (NR). Therefore, new subcarrier spacing may be introduced. For example, the 3GPP® RAN86 specification defines a new item of “NR above 52.6 GHz”. The main scope of this item is channel access for numerology, RAN1 and RAN2, which may lead to introducing new subcarrier spacing. The introduction of new subcarrier spacing brings about the problem of how to establish or confirm a combination of physical uplink shared channel (PUSCH) subcarrier spacing and physical random access channel (PRACH) subcarrier spacing. For example, when a new PRACH subcarrier spacing is introduced, the present disclosure describes a new rule, i.e., a rule for establishing or confirming a combination of PUSCH subcarrier spacing and PRACH subcarrier spacing. The new rule allows a combination of PUSCH subcarrier spacing and PRACH subcarrier spacing, and those spacings are not capped by 120KHz. Either or both the PUSCH subcarrier spacing or the PRACH subcarrier spacing may exceed 120 KHz according to the new rules described herein.

The method 300 includes a step of the wireless communication device 104 or 204 determining the number of resource blocks to be occupied by a random access (RA) preamble.
