Abstract

This document generally relates to wireless communication schemes that include setting or determining PDCCH detection attempt parameters by setting or determining at least one of: a total DCI monitoring number, a specific DCI monitoring number, a non-overlapped CCE number, an aggregation level number, or a total PDCCH detection attempt number. The PDCCH detection attempt parameters may correspond to a reduced maximum number of PDCCH candidates per slot per serving cell, and/or a maximum number of non-overlapped CCEs per slot per serving cell. User devices, including reduced capability UEs, may utilize the PDCCH detection attempt parameters when detecting or blindly decoding PDCCH candidates.

Claims16

Dependent claims

A method for wireless communication, the method comprising:

identifying, by a wireless access node, a sub-carrier spacing (SCS) configuration from among a plurality of SCS configurations;
selecting, by the wireless access node, a set of individual physical downlink control channel (PDCCH) detection attempt parameters from among a plurality of sets of individual PDCCH detection attempt parameters depending on the identified SCS configuration;
setting, by a wireless access node, PDCCH detection attempt parameters for a user device by:
setting a total PDCCH detection attempt number no larger than a predetermined maximum total PDCCH detection attempt number according to the selected set of individual PDCCH detection attempt numbers;
and
transmitting, by the wireless access node to the user device, at least one of:
the PDCCH detection attempt parameters;
one or more DCIs according to the PDCCH detection attempt parameters;
or
at least one PDCCH according to the PDCCH detection attempt parameters.
