Abstract:
Methods and apparatuses for wireless communication are described. One of the methods comprises transmitting, by a first wireless communication device, a signal in a control channel that indicates a selection of a mapping configuration from different mapping configurations that map at least one resource block to a plurality of different resource block groups, each of the resource block group comprises a set of resource blocks, the different resources groups comprising different symbols, and the signal further indicates a size of the resource block group and a size of contiguously allocated resource blocks in the resource block group and the selection of the mapping configuration is further based on the size of the resource block group and the size of the contiguously allocated resource blocks, wherein the at least one resource block carries data to be transmitted to a second wireless communication device and transmitting data, from the first wireless communication device to the second wireless communication device, using the at least one resource block mapped to a particular resource block group of the plurality of resource block groups using the selected mapping configuration.
Abstract:
In aspects, an initial access procedure may include a random access channel (RACH) procedure. Thereby, a user equipment (UE) may transmit, to a base station, a random access channel preamble over a first bandwidth of a system bandwidth that is less than the system bandwidth, receive, from the base station after transmitting the random access channel preamble, a random access channel response over the first bandwidth, receive, from the base station after transmitting the random access channel preamble, one or more reference signals over one or more portions of a second bandwidth of the system bandwidth, the second bandwidth being wider than the first bandwidth, the one or more portions of the second bandwidth being different than the first bandwidth, the one or more reference signals being usable for determining a beam to be used for data communication over the second bandwidth, and receive, from the base station, a physical downlink shared channel (PDSCH) over the second bandwidth via the beam based on the one or more reference signals.
Abstract:
The apparatus and methods described herein are used to provide a communication quality feedback of an end-to-end communication path between an application transmitter and an application receiver. One method includes transmitting data from the application transmitter to the application receiver via the end-to-end communication path, the end-to-end communication path having at least one wireless link with a wireless transmitter and a wireless receiver, generating, at the wireless transmitter, a first communication quality feedback message, and transmitting the first communication quality feedback message from the wireless transmitter to the application transmitter in a standardized format.
Abstract:
Apparatus and methods for updating symbol information in a communication device with hardware such as a microcontroller are disclosed. The disclosed apparatus and methods employ waiting for the beginning of a symbol in a sample stream at a predetermined time. One or more programmed instructions are read at the beginning of the symbol, and then symbol information is updated based on the one or more programmable instructions and setting a time for a beginning of a next symbol. The programmed instructions consist of instruction code words that are executed by a dedicated microcontroller or similar hardware, which affords flexibility for updating symbol information, particularly for multimode communication devices operable across multiple communication technologies.
