Abstract

A user equipment (UE) is configured to receive a measurement configuration from a serving cell, wherein the measurement configuration comprises event configuration associated with radio resource management (RRM) relaxation, perform measurements of the serving cell, transmit a measurement report to the serving cell and receive an indication from the serving cell that RRM relaxation for radio resource control (RRC) connected mode is enabled at the UE.

Claims (32)

1 . A processor of a user equipment (UE) configured to perform operations comprising:

receiving a measurement configuration from a serving cell, wherein the measurement configuration comprises event configuration associated with radio resource management (RRM) relaxation;

performing measurements of the serving cell;

transmitting a measurement report to the serving cell; and

receiving an indication from the serving cell that RRM relaxation for radio resource control (RRC) connected mode is enabled at the UE, wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to one or more of a primary synchronization signal (PSS)/secondary synchronization signal (SSS) detection time configuration, a synchronization signal block (SSB) measurement time configuration or a time index detection configuration and wherein, during RRM relaxation for RRC connected mode, discontinuous reception (DRX) is configured at the UE and measurement gaps are not used at the UE.

2 . The processor of claim 1 , wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to a discontinuous reception (DRX) cycle periodicity.

3 . The processor of claim 1 , wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to a measurement gap repetition period (MGRP).

4 . The processor of claim 1 , wherein RRM relaxation for RRC connected mode comprises implementing a fixed detection time.

5 . The processor of claim 1 , wherein RRM relaxation for RRC connected mode comprises implementing a fixed measurement time.

6 . A user equipment (UE), comprising:

a transceiver configured to communicate with a serving cell; and

a processor communicatively coupled with the transceiver and configured to perform operations comprising:

receiving a measurement configuration from the serving cell, wherein the measurement configuration comprises event configuration associated with radio resource management (RRM) relaxation;

performing measurements of the serving cell;

transmitting a measurement report to the serving cell; and

receiving an indication from the serving cell that RRM relaxation for radio resource control (RRC) connected mode is enabled at the UE, wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to one or more of a primary synchronization signal (PSS)/secondary synchronization signal (SSS) detection time configuration, a synchronization signal block (SSB) measurement time configuration or a time index detection configuration and wherein, during RRM relaxation for RRC connected mode, discontinuous reception (DRX) is configured at the UE and measurement gaps are not used at the UE.

7 . The UE of claim 6 , wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to a discontinuous reception (DRX) cycle periodicity.

8 . The UE of claim 6 , wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to a measurement gap repetition period (MGRP).

9 . The UE of claim 6 , wherein RRM relaxation for RRC connected mode comprises implementing a fixed detection time.

10 . The UE of claim 6 , wherein RRM relaxation for RRC connected mode comprises implementing a fixed measurement time.

11 . A method, comprising:

transmitting a measurement configuration to a reduced capability (redcap) user equipment (UE), wherein the measurement configuration comprises event configuration associated with radio resource management (RRM) relaxation for radio resource control (RRC) connected mode;

receiving one or more RRC messages from the redcap UE, the one or more RRC messages comprising a measurement report and an explicit indication that RRM relaxation criterion has been fulfilled, wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to a discontinuous reception (DRX) cycle periodicity; and

transmitting an indication to the redcap UE that the RRM relaxation for RRC connected mode is enabled at the redcap UE.

12 . The method of claim 11 , wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to a measurement gap repetition period (MGRP).

13 . The method of claim 11 , wherein RRM relaxation for RRC connected mode comprises implementing a fixed detection time.

14 . The method of claim 11 , wherein RRM relaxation for RRC connected mode comprises implementing a fixed measurement time.

15 . The method of claim 11 , wherein RRM relaxation for RRC connected mode comprises applying a scaling factor to one or more of a primary synchronization signal (PSS)/secondary synchronization signal (SSS) detection time configuration, a synchronization signal block (SSB) measurement time configuration or a time index detection configuration.

16 . The method of claim 15 , wherein, during RRM relaxation for RRC connected mode, discontinuous reception (DRX) is not configured and measurement gaps are not used by the redcap UE.

17 . The method of claim 15 , wherein, during RRM relaxation for RRC connected mode, discontinuous reception (DRX) is configured at the UE and measurement gaps are not used at the redcap UE.

18 . The method of claim 15 , wherein, during RRM relaxation for RRC connected mode, discontinuous reception (DRX) is not configured at the UE and measurement gaps are used at the redcap UE.

19 . The method of claim 15 , wherein, during RRM relaxation for RRC connected mode, discontinuous reception (DRX) is configured at the UE and measurement gaps are configured at the redcap UE.
