Abstract
Certain aspects of the present disclosure propose techniques for utilizing synchronization shift (SS) bits in Time Division Synchronous Code Division Multiple Access (TD-SCDMA) based uplink communications. The SS bits can be used for various purposes different from indicating timing of transmissions from a Node B to a user equipment.
Claims32
A method of wireless communication, comprising:
- receiving, in at least one downlink time slot of a subframe, at least one uplink timing adjustment element indicating timing of uplink transmission;
- generating, in at least one uplink time slot of the subframe, at least a downlink timing adjustment element, a power control element, and data, the downlink timing adjustment element comprising an indication for adjusting power for downlink transmission such that the downlink timing adjustment element does not indicate timing of a downlink transmission;
- and
- transmitting at least the downlink timing adjustment element, the power control element, and the data.
