Abstract
Methods related to wireless communication systems and scheduling channel state information operations and transmissions. A user equipment (UE) receives, from a base station (BS), a channel state information (CSI) computation request. The UE then identifies a first CSI measurement resource based on the CSI computation request. The UE determines CSI based on the first CSI measurement resource, and receives, from the BS, a CSI report transmission request associated with the first CSI measurement resource. The UE optionally transmits to the BS a CSI report based on the first CSI measurement resource or a different CSI measurement resource. Other features are also claimed and described.
Claims34
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a network entity, a channel state information (CSI) computation request that indicates a first CSI measurement resource;
- determining, based on the first CSI measurement resource, CSI;
- starting, after a first duration has elapsed from an end time of the first CSI measurement resource, a timer, wherein the timer is configured to define a window during which the UE expects to receive a CSI report transmission request and to determine whether to transmit the CSI based on whether the CSI report transmission request is received within the window;
- and
- receiving, from the network entity after the CSI computation request, the CSI report transmission request that requests transmission of the CSI determined using the first CSI measurement resource.

A method of wireless communication performed by a network entity, comprising:
- transmitting, to a user equipment (UE), a channel state information (CSI) computation request that indicates a first CSI measurement resource;
- transmitting, to the UE, a CSI report transmission request that requests transmission of CSI determined using the first CSI measurement resource, wherein the CSI report transmission request is associated with a window during which the UE expects to receive the CSI report transmission request and determine whether to transmit the CSI based on whether the CSI report transmission request is received within the window, and wherein the window is defined by a timer started after a first duration has elapsed from an end time of the first CSI measurement resource;
- and
- receiving, from the UE and based on the CSI report transmission request being received during the window, a CSI report including the CSI determined using the first CSI measurement resource.
1 more element
A user equipment (UE), comprising:
- one or more transceivers configured, individually or collectively, to:
- receive, from a network entity, a channel state information (CSI) computation request that indicates a first CSI measurement resource;
- and
- one or more processors configured, individually or collectively, to:
- determine, based on the first CSI measurement resource, CSI;
- and
- start, after a first duration has elapsed from an end time of the first CSI measurement resource, a timer, wherein the timer is configured to define a window during which the UE expects to receive a CSI report transmission request and to determine whether to transmit the CSI based on whether the CSI report transmission request is received within the window, wherein the one or more transceivers are further configured, individually or collectively, to:
- receive, from the network entity after the CSI computation request, the CSI report transmission request that requests transmission of the CSI determined using the first CSI measurement resource.
5 more elements
A network entity, comprising:
- one or more processors;
- and
- one or more transceivers, coupled to the one or more processors, configured, individually or collectively, to:
- transmit, to a user equipment (UE), a channel state information (CSI) computation request that indicates a first CSI measurement resource;
- transmit, to the UE after the CSI computation request, a CSI report transmission request that requests transmission of CSI determined using the first CSI measurement resource, wherein the CSI report transmission request is associated with a window during which the UE expects to receive the CSI report transmission request and determine whether to transmit the CSI based on whether the CSI report transmission request is received within the window, and wherein the window is defined by a timer started after a first duration has elapsed from an end time of the first CSI measurement resource;
- and
- receive, from the UE and based on the CSI report transmission request being received during the window, a CSI report including the CSI.
4 more elements
A user equipment (UE), comprising:
- means for receiving, from a network entity, a channel state information (CSI) computation request that indicates a first CSI measurement resource;
- means for determining, based on the first CSI measurement resource, CSI;

- and
- means for receiving, from the network entity after the CSI computation request, the CSI report transmission request that requests transmission of the CSI determined using the first CSI measurement resource.
