According to certain embodiments, a method in a network node (100A) for determining spectrum utilization for a plurality of numerologies transmitted within an allocated bandwidth includes selecting one or more of the plurality of numerologies. For each of the one or more selected numerologies, a spectrum utilization is determined. The spectrum utilization is based on the spectrum utilization that would be achieved if the selected numerology was transmitted across the allocated bandwidth. A physical resource block (PRB) allocation is calculated based on the allocated bandwidth and the spectrum utilization.

A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

Provided is a transmitter which improves the flexibility of SRS resource allocation without increasing the amount of signaling for notifying the cyclic shift amount. In the transmitter, with regard to each basic shift amount candidate group having a basic shift amount from 0 to N−1, a transmission control unit (206) specifies the actual shift amount imparted to a cyclic shift sequence used in scrambling a reference signal transmitted from each antenna port, said specification being performed based on a table in which cyclic shift amount candidates correspond to each antenna port, and based on setting information transmitted from a base station (100). With regard to basic shift amount candidates for shift amount X, the table differentiates between an offset pattern comprising offset values for cyclic shift amount candidates corresponding to each antenna port and an offset pattern corresponding to basic shift amount candidates of X+N/2.

A wireless communication method for use in a user terminal comprises receiving, from a network entity or a first wireless network node, prior channel information related to at least one channel between each of at least one wireless terminal and each of at least one second wireless network node, and determining at least one characteristic of the user terminal based on the prior channel information.

A method and an apparatus for transmitting a random access signal. The method includes receiving configuration information, wherein the configuration information indicates a random access preamble length, a random access signal subcarrier spacing, and a data subcarrier spacing, determining a subcarrier quantity parameter k based on at least one of the random access preamble length, the random access signal subcarrier spacing, or the data subcarrier spacing, generating a random access signal based on the subcarrier quantity parameter k, and sending the random access signal.

A method of processing data includes: receiving, by a Packet Data Convergence Protocol (PDCP) layer, a PDCP Service Data Unit (SDU) from an upper layer; and deleting the PDCP SDU and a PDCP Packet Data Unit (PDU) corresponding to the PDCP SDU upon determining that a discard timer corresponding to the PDCP SDU is not expired and a preset condition is satisfied. The PDCP SDU is mapped to an Unacknowledged Mode (UM) or a Transparent Mode (TM) of a Radio Link Control (RLC) layer. Thus, the PDCP SDU will not reside in a UE cache, thereby reducing cache space occupied by the PDCP SDU.

A base station can select orthogonal frequency-division multiplexing (OFDM) numerologies that define subcarrier spacing values based on attributes associated with one or more services that a user equipment (UE) is using. The base station can use the selected OFDM numerologies for transmission associated with the services. When the UE is using multiple services simultaneously, the base station can select the same or different OFDM numerologies for the multiple services.

Systems and methods for analyzing available networks and transferring data via a two-way radio transmission are described herein. An example method may commence with collecting, by a data collection device, asset data. The method may continue with preprocessing, by the data collection device, the asset data for transmission. The method may further include dynamically analyzing, by the data collection device, networks available for transmission of the asset data determining a mode for the transmission of the asset data. The method may further include transmitting, by at least one of the data collection device and a two-way radio device communicatively coupled to the data collection device, the asset data to a data server. The asset data may be transmitted based on the mode for the transmission via at least one communication channel and at least one intermediate device.

Embodiments are provided herein for improving carrier aggregation for wireless networks. A plurality of bandwidth channels are assigned to a basic service set (BSS) for transmissions. Specifically, the bandwidth channels are divided into multiple channel segments corresponding to multiple primary or alternate primary channels. A channel segment possibly further includes one or more additional secondary channels. The locations of the primary or alternate primary channels that correspond to the channel segments of the BSS are then broadcasted in the network. When a station or AP receives this BSS information, it searches for an available primary or alternate primary channel of the BSS to begin transmission. Upon detecting an available primary channel or alternate primary channel that is not used for another transmission, the station or AP transmits data on the channel segment corresponding to the detected primary or alternate primary channel.

Embodiments of the disclosure provide bandwidth allocation in wireless telecommunications including communication devices that can operate according to different operating bandwidth. The bandwidth allocation can include allocation of subcarrier blocks having specific sizes. The subcarriers blocks can be contiguous within a channel or can be non-contiguous or distributed.
