摘要： Wireless communications using multiple active resources (e.g., bandwidth parts (BWP)) are described. A predetermined rule may be used to determine on which downlink (DL) BWP of multiple active DL BWPs, and/or on which uplink (UL) BWP of multiple active UL BWPs, a message is to be sent. A wireless device and/or a base station may reduce the quantity of active DL BWPs and/or active UL BWPs to monitor for a response.

摘要： A network node, such as a base station, identifies radio resources within an overall bandwidth using a first resource referencing scheme, while a wireless communication device identifies radio resources within an allocated portion of the overall bandwidth using a second resource referencing scheme. Advantageously, the device correctly identifies given radio resources pointed to by a resource identifier expressed according to the first resource referencing scheme, by translating the resource identifier into the second resource referencing scheme according to mapping information that relates the two schemes. Correspondingly, the network node enables the wireless communication device to perform such translations by providing the mapping information either implicitly or explicitly.

摘要： An apparatus and a related method for determining an assignment of Resource Blocks (RBs) from one or more Cell Tower (CTs) to a plurality of User Equipment devices (UEs), the assignment minimizing a total assignment cost is provided. The method includes modifying a system of equations by introducing a plurality of dummy UEs therein. The system of equations is defined using a cost matrix, a RB-Supply vector and a RB-Demand vector. The method also includes modifying the system of equations by introducing one or more dummy CTs therein and resolving the system of equations using a Customized Hungarian method. The method in addition includes reversing the modification made by introducing the dummy CTs and reversing the modification made by introducing the dummy UEs, thereby obtaining the assignment.

摘要： A vehicle may wirelessly communicate with another vehicle via a physical channel (a vehicle-to-vehicle (V2V) channel) that is robust and reliable under high mobility propagation conditions. The physical channel may be created by modifying an existing long-term evolution (LTE) physical channel, such as an LTE sidelink (SL) channel. For instance, the V2V physical channel may be created by increasing, by a particular factor, the subcarrier spacing of legacy LTE channels (e.g., from 15 kilohertz (kHz) to 30 kHz). Additionally, a symbol duration and a fast Fourier transform (FFT) size for the V2V physical channel may each be reduced by the same factor. Doing so may enable the V2V physical channel to be implemented without significant modifications to other aspects of the LTE standard.

摘要： Certain aspects of the present disclosure relate to methods and apparatus mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs) and using the mapping in wireless communications, for example, in new radio (NR) technologies. An exemplary method includes determining a first interleaved mapping that maps a first interleaving unit of N consecutive first virtual resource blocks (VRBs) to N consecutive first physical resource blocks (PRBs), wherein each first PRB comprises a set of frequency resources during a period, transmitting a first grant allocating the first interleaving unit of first VRBs to a first user equipment (UE), and communicating with the first UE via the first PRBs mapped to the first VRBs of the first interleaving unit.
