Abstract
A wireless communication device receives an indication of timing alignment of a discontinuous reception (DRX) duration, determines a timing alignment for a reception/transmission (RX/TX) switching pattern of the wireless communication device based on the timing alignment of the DRX duration, and performs half-duplex (HD) communication with a radio access node according to the RX/TX switching pattern having the determined timing alignment.
Claims16
A method of operating a wireless communication device, the method comprising:
- receiving an indication of timing alignment of a discontinuous reception (DRX) duration from a network to which the wireless communication device is connected;
- determining a timing alignment for a reception/transmission (RX/TX) switching pattern of the wireless communication device based on the timing alignment of the DRX duration, wherein the DRX duration is a DRX ON duration, and wherein a start time of an RX state of the RX/TX switching pattern is aligned with respect to a fixed time offset from a start time of the DRX ON duration;
- performing half-duplex (HD) communication with a radio access node in the network according to the RX/TX switching pattern having the determined timing alignment;
- and
- receiving, from the network, an indication during an RX window of the RX/TX switching pattern to extend the RX window, wherein the indication received during the RX window is included in a medium access control (MAC) control element (CE) indicating a number of subframes by which the RX window is to be extended.

A method of operating a radio access node, the method comprising:
- transmitting an indication of timing alignment of a discontinuous reception (DRX) duration in a network that comprises the radio access node;
- transmitting an indication of a DRX offset that, in combination with the timing alignment of the DRX duration, defines a timing alignment for a reception/transmission (RX/TX) switching pattern of a wireless communication device connected to the network, wherein the DRX duration is a DRX ON duration, and wherein a start time of an RX state of the RX/TX switching pattern is aligned with respect to a fixed time offset from a start time of the DRX ON duration;
- performing half-duplex (HD) communication with the wireless communication device according to the RX/TX switching pattern having the defined timing alignment;
- and
- transmitting an indication during an RX window of the RX/TX switching pattern to extend the RX window, wherein the indication transmitted during the RX window is included in a medium access control (MAC) control element (CE) indicating a number of subframes by which the RX window is to be extended.
