Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may enable selection of a modulation order (Qm) parameter, a transport block size (TBS) parameter, a quantity of subframes in a transport block (NSF) parameter, and/or the like. For example, based at least in part on receiving a downlink control information or another factor, a user equipment may select, for example, a table of Qm, TBS, and NSF values and may select a particular set of a Qm value, a TBS value, and an NSF value from the table. In this way, the UE may use a higher order modulation and coding scheme in, for example, a narrowband Internet of Things deployment.
Claims28
A method of wireless communication, comprising:
- receiving, by a user equipment (UE), control information identifying a set of parameters associated with a first narrowband downlink shared channel modulated with at least 16-quadrature amplitude modulation (16-QAM);
- and
- determining, by the UE, a resource allocation configuration for the first narrowband downlink shared channel based at least in part on the control information and based at least in part on an overhead associated with resources available for a 16 QAM transmission on the first narrowband downlink shared channel,
- wherein the resource allocation configuration indicates:
- a quantity of one or more subframes for the first narrowband downlink shared channel, and
- a quantity of repetitions, of a subframe of the one or more subframes, for the 16-QAM transmission, and
- wherein the overhead is based at least in part on a value of a starting orthogonal frequency division multiplexing (OFDM) symbol index in the subframe.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive control information identifying a set of parameters associated with a first narrowband downlink shared channel modulated with at least 16-quadrature amplitude modulation (16-QAM);
- and
- determine a resource allocation configuration for the first narrowband downlink shared channel based at least in part on the control information and based at least in part on an overhead associated with resources available for a 16-QAM transmission on the first narrowband downlink shared channel,
- wherein the resource allocation configuration indicates:
- a quantity of one or more subframes in the first narrowband downlink shared channel, and
- a quantity of repetitions, of a subframe of the one or more subframes, for the 16-QAM transmission, and
- wherein the overhead is based at least in part on a value of a starting orthogonal frequency division multiplexing (OFDM) symbol index in the subframe.
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
- receive control information identifying a set of parameters associated with a first narrowband downlink shared channel modulated with at least 16-quadrature amplitude modulation (16-QAM);
- and
- determine a resource allocation configuration for the first narrowband downlink shared channel based at least in part on the control information and based at least in part on an overhead associated with resources available for a 16-QAM transmission on the first narrowband downlink shared channel,
- wherein the resource allocation configuration indicates:
- a quantity of one or more subframes in the first narrowband downlink shared channel, and
- a quantity of repetitions, of a subframe of the one or more subframes, for the 16-QAM transmission, and
- wherein the overhead is based at least in part on a value of a starting orthogonal frequency division multiplexing (OFDM) symbol index in the subframe.
An apparatus for wireless communication, comprising:
- means for receiving control information identifying a set of parameters associated with a first narrowband downlink shared channel modulated with at least 16-quadrature amplitude modulation (16-QAM);
- and
- means for determining a resource allocation configuration for the first narrowband downlink shared channel based at least in part on the control information and based at least in part on an overhead associated with resources available for a 16-QAM transmission,
- wherein the resource allocation configuration indicates:
- a quantity of one or more subframes in the first narrowband downlink shared channel, and
- a quantity of repetitions, of a subframe of the one or more subframes, for the 16-QAM transmission, and
- wherein the overhead is based at least in part on a value of a starting orthogonal frequency division multiplexing (OFDM) symbol index in the subframe.
