Example embodiments of the present invention may be implemented using various physical layer modulation and transmission mechanisms. Example transmission mechanisms may include, but are not limited to: CDMA, OFDM, TDMA, wavelet techniques, and/or the like.

Fig. 1 is a diagram depicting an example set of OFDM subcarriers in accordance with an aspect of an embodiment of the present disclosure. As illustrated in this example, one or more arrows in the figures may depict subcarriers in a multicarrier OFDM system. The OFDM system may use techniques such as OFDM techniques, DFTS-OFDM, SC-OFDM techniques, and the like. For example,
Fig. 2 is a diagram depicting example transmit and receive times for two carriers, in accordance with aspects of an embodiment of the disclosure. A multi-carrier OFDM communication system may comprise one or more carriers, for example in the range of 1 to 10 carriers. Carrier a204 and carrier B205 may have the same or different timing structures.

Fig. 3 is a diagram depicting OFDM radio resources in accordance with an aspect of an embodiment of the disclosure. The resource grid structure in time 304 and frequency 305 is illustrated in fig. 3. The number of downlink subcarriers or RBs may depend at least in part on the configured downlink transmission bandwidth 306 in the cell. The smallest radio resource unit may be referred to as a resource element (e.g., 301). The resource elements may be grouped into resource blocks (e.g., 302). The resource blocks may be grouped into larger radio resources (e.g., 303) called Resource Block Groups (RBGs). The transmitted signal in
In an example embodiment, multiple base parameters may be supported. In an example, the base parameter may be derived by scaling the base subcarrier spacing by an integer N. In an example, the scalable base parameters may allow for at least a 15kHz to 480kHz subcarrier spacing. A base parameter with 15kHz and a scaled base parameter with the same CP overhead with different subcarrier spacing may be aligned every 1ms at the symbol boundary in the NR carrier.
Fig. 5A, 5B, 5C, and 5D are example diagrams of uplink and downlink signal transmissions in accordance with aspects of embodiments of the present disclosure. Fig. 5A illustrates an example uplink physical channel. The baseband signal representing the physical uplink shared channel may perform the following process. These functional illustrations are examples, and it is contemplated that other mechanisms may be implemented in various embodiments. The functions may include scrambling, modulating the scrambled bits to produce complex-valued symbols, mapping the complex-valued modulation symbols onto one or several transmission layers, transforming the precoding to produce complex-valued symbols, precoding the complex-valued symbols, mapping the precoded complex-valued symbols to resource elements, producing complex-valued time-domain DFTS-OFDM/SC-FDMA signals for antenna ports, and/or the like.
An example modulation and up-conversion of the carrier frequency of the complex-valued DFTS-OFDM/SC-FDMA baseband signal and/or the complex-valued PRACH baseband signal for the antenna ports is shown in fig. 5B. Filtering may be employed prior to transmission.
An example structure for downlink transmission is shown in fig. 5C. The baseband signal representing the downlink physical channel may perform the following process. These functional illustrations are examples, and it is contemplated that other mechanisms may be implemented in various embodiments. The functions include: scrambling decoded bits in a codeword to be transmitted on a physical channel; modulating the scrambled bits to produce complex-valued modulation symbols; mapping the complex-valued modulation symbols onto one or several transmission layers; pre-decoding complex-valued modulation symbols on a layer for transmission on an antenna port; mapping complex-valued modulation symbols for antenna ports to resource elements; generating a complex-valued time-domain OFDM signal for an antenna port; and/or the like.
An example modulation and up-conversion of the carrier frequency of the complex-valued OFDM baseband signal for the antenna port is shown in fig. 5D. Filtering may be employed prior to transmission.

The interface may be a hardware interface, a firmware interface, a software interface, and/or a combination thereof. The hardware interface may include connectors, wires, electronics (e.g., drivers, amplifiers, etc.), and/or the like. The software interface may include code stored in the memory device to implement protocol(s), protocol layers, communication drivers, device drivers, combinations thereof, and the like. The firmware interface may include a combination of embedded hardware and code stored in and/or in communication with the memory device to implement connections, electronic device operations, protocols, protocol layers, communication drivers, device drivers, hardware operations, combinations thereof, and/or the like.
The term "configuration" may mean the capability of a device, whether the device is in an operational state or a non-operational state. "configuration" may also mean a particular setting in a device that affects an operational characteristic of the device, whether the device is in an operational state or a non-operational state. In other words, hardware, software, firmware, registers, memory values, etc. may be "configured" within a device, whether the device is in an operational or non-operational state, to provide particular characteristics to the device. Terms like "control message in a device that causes …" or the like may mean that the control message has parameters that can be used to configure a particular feature in the device, whether the device is in an operational state or a non-operational state.
According to some of the various aspects of the embodiments, a 5G network may include a large number of base stations, providing user plane NR PDCP/NR RLC/NR MAC/NR PHY and control plane (NR RRC) protocol terminals for wireless devices. The base stations may be interconnected with other base stations (e.g., using an Xn interface). The base station may also be connected to the NGC using, for example, an NG interface. Fig. 10A and 10B are example diagrams for an interface between a 5G core network (e.g., NGC) and base stations (e.g., gNB and etlenb) in accordance with aspects of embodiments of the present disclosure. For example, a NG-C interface may be employed to interconnect base stations to an NGC control plane (e.g., NG CP) and an NG-U interface may be employed to interconnect base stations to an NGC user plane (e.g., UPGW). The NG interface may support a many-to-many relationship between the 5G core network and the base station.
A base station may include many sectors, such as: 1. 2, 3, 4 or 6 sectors. A base station may comprise many cells, for example ranging from 1 to 50 cells or more. A cell may be classified as, for example, a primary cell or a secondary cell. One serving cell may provide non-access stratum (NAS) mobility information (e.g., TAI) at RRC connection establishment/re-establishment/handover and one serving cell may provide security input at RRC connection re-establishment/handover. This cell may be referred to as a primary cell (PCell). In the downlink, a carrier corresponding to the PCell may be a downlink primary component carrier (DL PCC), and in the uplink, it may be an uplink primary component carrier (UL PCC). Depending on wireless device capabilities, a secondary cell (SCell) may be configured to form a set of serving cells with a PCell. In downlink, a carrier corresponding to the SCell may be a downlink secondary component carrier (DL SCC), and in uplink, the carrier may be an uplink secondary component carrier (UL SCC). The SCell may or may not have an uplink carrier.
A cell including a downlink carrier and an optional uplink carrier may be assigned a physical cell ID and a cell index. A carrier (downlink or uplink) may belong to only one cell. The cell ID or cell index may also identify the downlink carrier or uplink carrier of the cell (depending on the context in which it is used). In the specification, the cell ID may be equivalently referred to as a carrier ID, and the cell index may be referred to as a carrier index. In an embodiment, a physical cell ID or cell index may be assigned to a cell. The cell ID may be determined using a synchronization signal transmitted on a downlink carrier. The cell index may be determined using RRC messages. For example, when the specification refers to a first physical cell ID for a first downlink carrier, the specification may mean that the first physical cell ID is for a cell that includes the first downlink carrier. The same concept can be applied to e.g. carrier activation. When the specification indicates activation of the first carrier, the specification may likewise mean activation of a cell including the first carrier.
