NEW RADIO (NR) MULTI-INPUT MULTI-OUTPUT (MIMO) CHANNEL STATE INFORMATION (CSI) DESIGN FOR SMALL BANDWIDTH PART (BWP)

Some aspects of this disclosure relate to apparatuses and methods for implementing capability signaling design for 3rd Generation Partnership Project (3GPP) release 15 (Rel-15) and/or release 16 (Rel-16) multi-input multi-output (MIMO) enhancement. For example, systems and methods are provided implementing designs for New Radio (NR) MIMO channel state information (CSI) for a small bandwidth part (BWP) and/or a small number of subbands. For example, some aspects relate to a user equipment (UE) including a transceiver configured to communicate with a base station and a processor communicatively coupled to the transceiver. The processor receives, from the base station, a CSI reporting configuration message. The processor determines, using the CSI reporting configuration message, that a number of physical resource blocks (PRBs) of a BWP associated with the CSI reporting configuration message is less than a threshold number. The processor also generates and transmits a CSI report for the BWP.

20230039220 · 2023-02-09 ·

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to switch a beam used by the UE, wherein the indication triggers at least one of a reference signal for a beam measurement or a transmission of a measurement report, based at least in part on an association of the beam with the reference signal or the measurement report. The UE may receive the reference signal associated with the beam measurement based at least in part on receiving the indication to switch the beam. The UE may transmit, using one or more transmission parameters, the measurement report indicating a measurement of the reference signal, wherein the one or more transmission parameters are based at least in part on receiving the indication to switch the beam. Numerous other aspects are described.

Non-orthogonal design for channel state information reference signals for a 5G air interface or other next generation network interfaces

Channel state information reference signal transmission can be used to estimate channel state information. Although resources needed for channel state information reference signals can be small, when multiple bandwidths are deployed within the same orthogonal frequency division multiplexing bandwidth, estimating the channel state information can comprise a channel state information reference signal resource grid for every bandwidth. Therefore, time-frequency resources for channel state information reference signals can be high and occupy a lot of bandwidth, thereby reducing the number of resources for data transmission. Therefore, a non-orthogonal design for channel state information reference signals for a 5G air interface can mitigate bandwidth loss in a 5G network.

Enhancements to channel state information reporting

Certain aspects of the present disclosure provide techniques for enhancements to channel state information (CSI) reporting. A method that may be performed by a user equipment (UE) includes obtaining, from a network entity, a CSI reporting configuration for reporting CSI for a channel. The method further includes generating a model of an interference pattern for the channel, and predicting one or more candidate interference levels for one or more upcoming slots using the model. The method further includes reporting information regarding the candidate interference levels to the network entity.
