Abstract: A sidelink (SL) configuration for SL communications directly between a communication terminal and another communication terminal is separate from a communication network link configuration for communications with network equipment in some embodiments. An SL configuration, which could be an SL reconfiguration or an SL preconfiguration for use by the communication terminal after the terminal transitions from in coverage to out of coverage, could be transmitted through network/terminal signaling, and detailed examples of such signaling are disclosed herein. An SL configuration could be or include an SL bandwidth part (BWP) configuration and an SL communication resource configuration, such as one or more resource pools, within the SL BWP. An SL configuration that is determined and transmitted by network equipment to one or more terminals could also or instead involve a common or initial SL configuration to be used for SL communications by multiple communication terminals.

Abstract: A method, system, and device to obtain a basic subcarrier spacing, or a channel bandwidth, or a maximum transmission bandwidth, or a usable subcarrier spacing set via a predefined mapping rule is provided. In an embodiment, a method in a network component to determine a system numerology includes determining, by the network component, one or more subcarrier spacing options from a candidate subcarrier spacing set that is associated with a carrier frequency band. The method also includes transmitting, by the network component, a signal indicating to one or more UEs one or more subcarrier spacing options from the candidate subcarrier spacing set.

Abstract: A method for a multicast service is provided. In this example, the method includes receiving, by a user equipment (UE), a control format including a resource allocation field from a base station (BS), the resource allocation field indicating a starting resource block (RB) index and an RB range, obtaining a set of RBs allocated for a multicast physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) based on a starting RB location and the RB range; wherein the starting RB location is associated with the stating RB index and at least one of a reference RB location or an assigned sub-band; and transmitting or receiving, by the UE, data over at least one RB of the set of RBs allocated for the multicast PDSCH or PUSCH.

Abstract: A method for transmitting data on multiple carriers, a terminal device, and a network device is disclosed. The method includes: receiving, by a terminal device, instruction information sent by a network device, where the instruction information is used to instruct the terminal device to perform cross-carrier time-frequency resource bundling; bundling, by the terminal device, time-frequency resources on a first type of carrier and a second type of carrier according to the instruction information; and sending or receiving, by the terminal device, data on the bundled time-frequency resources. The method for transmitting data on multiple carriers in the embodiments of the disclosure implements inter-carrier soft combination and decoding and increases a success rate of decoding.

Abstract: Examples communication methods and communications apparatus are described. In one example method, a base station sends a first synchronization signal block, where the first synchronization signal (SS) block includes a primary SS, a secondary SS, and information carried on a physical broadcast channel (PBCH). In addition, the base station sends a second SS block, where the second SS block includes a primary SS or includes a primary SS and a secondary SS, and does not include information carried on the PBCH. The first SS block is used by a terminal to access the base station. The second SS block is used to perform time and frequency synchronization after the terminal accesses the base station.

Abstract: A signal scrambling method and apparatus, and a signal descrambling method and apparatus are disclosed. In the signal scrambling method, a communications apparatus scrambles a signal by using a scrambling sequence, and sends the scrambled signal. In the signal descrambling method, a communications apparatus receives a signal, and descrambles the signal by using a scrambling sequence. An initial value of the scrambling sequence is determined based on a time unit number corresponding to a frame structure parameter used for transmitting the signal, so that different scrambling sequences can be used to scramble signals that are transmitted by using different frame structure parameters. Therefore, interference randomization can be implemented for signal scrambling, and this can be applicable to various application scenarios in 5G NR to improve performance.

Abstract: Systems and methods of synchronization channel design for radio access network (RAN) slicing are described. According to embodiments, a user equipment (UE) receives, from a first transmit point in a radio access network (RAN), a first synchronization signal over a first synchronization channel. The first synchronization channel is associated with a first RAN slice of a plurality of RAN slices in the RAN. The plurality of RAN slices comprise a second RAN slice associated with a second synchronization channel. The first synchronization channel and the second synchronization channel are different from a default synchronization channel of the first transmit point.
