Abstract
Radio communication systems, devices and methods for enabling variable subband configuration of one or more search spaces. In a first time interval, a UE attempts to decode one or more control channels on downlink or sidelink resources of a first subband configuration. In a second time interval, the UE attempts to decode one or more control channels on downlink or sidelink resources of a second subband configuration. The first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.
Claims39
A method implemented in a user equipment, UE, comprising:
- in a first time interval, attempting to decode one or more control channels on downlink or sidelink resources of a first subband configuration;
- and
- in a second time interval, attempting to decode one or more control channels on downlink or sidelink resources of a second subband configuration,
- wherein the first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.
A user equipment UE comprising a communication interface and processing circuitry configured to cause the UE:
- in a first time interval, to attempt to decode one or more control channels received using the communication interface on downlink or sidelink resources of a first subband configuration;
- and
- in a second time interval, attempt to decode one or more control channels received using the communication interface on downlink or sidelink resources of a second subband configuration,
- wherein the first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.
(canceled)
A method implemented in a network node, comprising:
- in a first time interval, transmitting a control channel on downlink or sidelink resources of a first subband configuration to a user equipment, UE;
- and
- in a second time interval, transmitting a control channel on downlink or sidelink resources of a second subband configuration to the UE,
- wherein the first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.
-43. (canceled)
The method of 28, wherein the first frequency range has a first bandwidth and the second frequency range has a second bandwidth different from the first bandwidth, and
- wherein the second bandwidth is greater than the first bandwidth, the method further comprising:
- in the first time interval, transmitting data in a first frequency range containing the first subband configuration but not the second subband configuration;
- and
- in the second time interval, transmitting data in a second frequency range containing the second subband configuration.

(canceled)
A network node comprising a communication interface and processing circuitry configured to cause the network node:
- in a first time interval, to transmit a control channel on downlink or sidelink resources of a first subband configuration to a UE;
- and
- in a second time interval, to transmit a control channel on downlink or sidelink resources of a second subband configuration to the UE,
- wherein the first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.

A computer program product comprising a computer-readable medium storing a computer program comprising computer-readable instructions for causing a programmable processor to perform a method implemented in a user equipment (UE), the method comprising:
- in a first time interval, attempting to decode one or more control channels on downlink or sidelink resources of a first subband configuration;
- and
- in a second time interval, attempting to decode one or more control channels on downlink or sidelink resources of a second subband configuration,
- wherein the first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.
