Signaling of frequency domain resource assignment

A method for receiving, by a user equipment (UE) from a network node in a wireless communication network, an assignment of frequency-domain resources of a communication channel shared with one or more further UEs, the method comprising:

• receiving, from the network node, a first indication of an active bandwidth part (BWP) usable for communicating via the shared communication channel, wherein the active BWP comprises NBWP,1size frequency-domain resource blocks (RBs);
• receiving, via a downlink control channel, a second indication of one or more assigned RBs within the active BWP, wherein:
• the second indication is encoded with a plurality of bits,
• the plurality of bits is related to a total number of RBs, NBWP,2size, within a BWP other than the active BWP, and
• the plurality of bits is insufficient to encode all assignable combinations of RBs within the active BWP;
• and
• decoding the second indication to obtain the one or more assigned RBs within the active BWP.

A network node configured to communicate with a plurality of user equipment (UEs) in a wireless communication network, the network node comprising:

• power supply circuitry configured to supply power to the network node;
• transceiver circuitry configured to communicate with the UEs;
• and
• processing circuitry operably coupled to the transceiver circuitry, whereby the processing circuitry and the transceiver circuitry are configured to:
• send, to a particular UE, a first indication of an active bandwidth part (BWP) usable for communicating via a shared communication channel, wherein the active BWP comprises NBWP,1size frequency-domain resource blocks (RBs);
• select one or more RBs, within the active BWP, to be assigned to the UE;
• encode a second indication of the one or more selected RBs using a plurality of available bits, wherein:
• the plurality of available bits is related to a total number of RBs, NBWP,2size, within a BWP other than the active BWP, and
• the plurality of available bits is insufficient to encode all assignable combinations of RBs within the active BWP;
• and
• send the encoded second indication to the UE via a downlink control channel.

A method for assigning, to a user equipment (UE) by a network node in a wireless communication network, frequency-domain resources of a communication channel shared with one or more further UEs, the method comprising:

• sending, to the UE, a first indication of an active carrier bandwidth part, BWP, usable for communicating via the shared communication channel, wherein the active BWP comprises NBWP,1size, frequency-domain resource blocks (RBs);
• selecting one or more RBs, within the active BWP, to be assigned to the UE;
• encoding a second indication of the one or more selected RBs using a plurality of available bits, wherein:
• the plurality of available bits is related to a total number of RBs, NBWP,2size, within a BWP other than the active BWP;
• and
• the plurality of available bits is insufficient to encode all assignable combinations of RBs within the active BWP;
• and
• sending the encoded second indication to the UE via a downlink control channel.
