Methods and apparatus for managing control and data transmissions for low cost user equipments

摘要

Certain aspects of the present disclosure relate to methods and apparatus for managing control and data transmissions for low cost UEs. In certain aspects, multiplexing of a control channel and data channel may be allowed in a Physical Resource Block (PRB) pair of a subframe. An indication may be provided to the UE regarding whether a portion of resources of the PRB pair not used to transmit the control channel is available for transmitting the data channel. In alternative aspects, control and data may be scheduled in different subframes, such that there is no need to multiplex them in a subframe or a PRB pair in a same subframe.

主权项

1. A method of wireless communication by a base station (BS), comprising:
transmitting on a control channel using a first portion of resources of at least one Physical Resource Block (PRB) pair of a subframe; providing an indication regarding whether a second portion of resources of the at least one PRB pair not used to transmit on the control channel is available for transmitting on a Physical Downlink Shared Channel (PDSCH); allocating PDSCH resources of PRB pairs that are available for transmitting on a control channel using a first resource allocation granularity that comprises an integer number of one or more enhanced Control Channel Elements (eCCEs); and allocating PDSCH resources of PRB pairs that are not available for transmitting on a control channel using a second resource allocation granularity that is different from the first resource allocation granularity.
