Enhancements for transmission over multiple carriers

摘要

Data is selectively transmitted over one or more carriers of a set of carriers. According to some aspects of the disclosure, a decision may be made to forgo the transmission of a preamble via one of the carriers (e.g., channels). For example, in a multi-carrier system, transmission of a preamble via one carrier may be inhibited if all of the data can be transmitted via another carrier. According to some aspects of the disclosure, a decision may be made to transmit different types of data on a single carrier rather than on multiple carriers. For example, a single carrier may be used to transmit schedule data and non-scheduled data if all of the data can be transmitted on one of the carriers (e.g., during a single transmission time interval). In this case, transmission of a preamble on another one of the carriers may therefore be inhibited.

主权项

1. A method of wireless communication by a user equipment, comprising:
determining, by the user equipment, a first quantity of data to be transmitted via at least one of a first carrier or a second carrier; determining, by the user equipment, a second quantity of data allowed to be transmitted via the second carrier; determining, by the user equipment, whether the first quantity exceeds the second quantity; when the first quantity exceeds the second quantity, transmitting, by the user equipment, a preamble via the first carrier; and when the first quantity is less than the second quantity, forgoing transmission of the preamble via the first carrier by the user equipment.
