US 2018/0324769 A1 · TECHNIQUES AND APPARATUSES FOR DOWNLINK CHANNEL MONITORING

Abstract

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a plurality of resource blocks of a short channel mapped using a short resource element group (sREG) to short control channel element (sCCE) mapping. The short channel may be a short physical downlink control channel (sPDCCH) or a short physical downlink shared channel (sPDSCH). The wireless communication device may process the short channel using the plurality of resource blocks. The plurality of resource blocks may be bundled into a set of resource block bundles based at least in part on the sREG-to-sCCE mapping.

Dependent claims

A wireless communication device, comprising:

a memory;
and
one or more processors coupled to the memory, the one or more processors configured to:
determine, when transmit diversity is enabled for a short channel and when using a short transmission time interval (sTTI) with the short channel, a monitoring period for receiving the short channel,
wherein the sTTI is associated with a duration that is shorter than a duration of a transmission time interval (TTI) used with another channel;
and
receive, during the monitoring period, the short channel based at least in part on determining the monitoring period for receiving the short channel,
wherein the short channel is a short physical downlink control channel (sPDCCH) or a short physical downlink shared channel (sPDSCH) and the monitoring period is determined based at least in part on a number of useable tones of the short channel being an integer multiple of 2.

A method of wireless communication performed by a wireless communication device, comprising:

determining, when transmit diversity is enabled for a short channel and when using a short transmission time interval (sTTI) with the short channel, a monitoring period for receiving the short channel,
wherein the sTTI is associated with a duration that is shorter than a duration of a transmission time interval (TTI) used with another channel;
and
receiving, during the monitoring period, the short channel based at least in part on determining the monitoring period for receiving the short channel,
wherein the short channel is a short physical downlink control channel (sPDCCH) or a short physical downlink shared channel (sPDSCH) and the monitoring period is determined based at least in part on a number of useable tones of the short channel being an integer multiple of 2.
