Title: Reduced power consumption by obtaining time domain resource allocation patterns in advance via additional signaling
Inventor: TANG JIA
IPC: H04W72/04
Filed: 2019-10-30
Abstract: According to the present invention, a device can acquire a time domain wireless resource allocation (TWRA) pattern corresponding to a transmission time interval (TTI) in the future, which is allocated to the device by a network and has not decoded control information corresponding to the device yet, through wireless signaling from the network. Accordingly, the device can use resources allocated by the acquired TWRA pattern to perform wireless communications during the TTI without decoding the control information for identifying the TWRA pattern in advance. The device can acquire the TWRA pattern by acquiring, from the network, an indication that the TWRA pattern remains while being associated with the future wireless communication of the device, until being differently indicated by the network, transmitting indications of desirable parameters associated with the future wireless communications and the TWRA pattern to the network, and/or transmitting a request for changing the network from a different TWRA pattern to the corresponding TWRA pattern to the network.
