US 2023/0145892 A1 · METHOD FOR ENHANCED SCHEDULING OF NETWORK RESOURCES FOR REDUCED CAPABILITY USER EQUIPMENTS

Abstract

Provided is a method to operate a base station that is part of a cellular network. The base station is configured to ascertain capability information from said reduced-capability user equipment indicating a capable uplink frequency bandwidth and a capable downlink frequency bandwidth. The method includes transmitting at least one first downlink signal for user equipment considering the received capability information, said first downlink signal indicating an assignment to a scheduled uplink frequency band, and scheduling information in the scheduled downlink frequency band for synchronously transmission in a predetermined nominal spacing to said scheduled uplink frequency band based on the center of the scheduled uplink frequency band and the scheduled downlink frequency band.

A method to operate a base station (BS) that is part of a cellular network (CN), the base station serving a plurality of user equipments (UE), the base station (BS) operating at least in one supported frequency band in uplink direction and one in downlink direction (SUFB, SDFB), wherein the plurality of user equipments comprises at least one which is qualified as reduced-capability user equipment, wherein the base station (BS) is configured to ascertain capability information from said reduced-capability user equipment indicating a capable uplink frequency bandwidth and a capable downlink frequency bandwidth (CBW),

wherein for scheduling the at least one reduced-capability user equipment (UE) the method comprises the steps for the base station (BS) of:
transmitting at least one first downlink signal for said user equipment (UE) considering the received capability information, said first downlink signal indicating an assignment (UA) to a scheduled uplink frequency band (SUB),
scheduling information in the scheduled downlink frequency band (SDB) for synchronously transmission in a predetermined nominal spacing (NMS) to said scheduled uplink frequency band (SUB) based on the center of the scheduled uplink frequency band (SUB) and the scheduled downlink frequency band (SDB).

A Base station (BS) that is part of a cellular network, the base station (BS) is configured to serve a plurality of user equipments, the base station (BS) operating at least in one supported frequency band in uplink direction and one in downlink direction, wherein the plurality of user equipments comprises at least one which is qualified as reduced-capability user equipment, wherein the base station (BS) is configured to ascertain capability information from said reduced-capability user equipment (UE) indicating a capable uplink frequency bandwidth and a capable downlink frequency bandwidth (CBW),

wherein for scheduling the at least one reduced-capability user equipment (UE) the base station (BS) is configured to:
transmit at least one first downlink signal for said user equipment (UE) considering the received capability information indicating an assignment (UA) to a scheduled uplink frequency band (SUB),
schedule information in the scheduled downlink frequency band (SDB) for synchronously transmission in a predetermined nominal spacing (NMS) to said scheduled uplink frequency band (SUB) based on the center of the scheduled uplink frequency band (SUB) and the scheduled downlink frequency band (SDB).

A method for a user equipment (UE) capable of operating with one of a plurality of base station (BS) of a cellular network (CN), hereinafter the serving base station, said user equipment (UE) is qualified as reduced-capability user equipment, said user equipment (UE) maintaining a capable uplink frequency bandwidth and a capable downlink frequency bandwidth (CBW),

the method comprising the steps of:
submitting capability information to the serving base station (BS),
receiving at least one first downlink signal from the serving base station (BS),
deriving from the first downlink signal the assignment (UA) to a scheduled uplink frequency band (SUB),
determining the scheduled downlink frequency band (SDB) by considering a predetermined nominal spacing (NMS) to the center of the scheduled uplink frequency band (SUB) and the scheduled downlink frequency band (SDB),
synchronously monitoring the scheduled downlink frequency band (SDB) for signals from the base station (BS) and transmitting at least one signal to the base station (BS) using the scheduled uplink frequency band (SUB).
