Abstract
Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.
Claims14
A method for wireless communication at a user equipment, comprising:
- determining a resource block allocation for a single-carrier waveform associated with time domain processing, wherein the resource block allocation is determined based on one of:
- (a) a semi-static assignment of resource blocks via radio resource control (RRC) signaling and varies based on a predetermined pattern received via a network entity indication, or
- (b) receiving a media access control (MAC) control element (CE),
- transmitting an acknowledgment to the network entity in response to receiving the MAC CE;
- and
- utilizing the resource block allocation a period of time after transmission of the acknowledgment to the network entity, or
- (c) receiving an assignment to one or more distinct resource block allocations via downlink control information (DCI), wherein the DCI includes a first stage cross-slot DCI controlling the resource block allocation and a second stage DCI indicating scheduling parameters other than the resource block allocation;
- configuring data for transmission or reception according to the single-carrier waveform and based on the determined resource block allocation;
- and
- transmitting or receiving the data according to the single-carrier waveform and the determined resource block allocation to a network entity.

A method for wireless communication at a network entity, comprising:
- determining, for a user equipment (UE), a resource block allocation for a single-carrier waveform associated with a time domain processing;
- and
- transmitting an indication including the resource block allocation to the UE, wherein the indication corresponds to a downlink control information (DCI) that includes a first stage cross-slot DCI controlling the resource block allocation and a second stage DCI indicating scheduling parameters other than the resource block allocation.
An apparatus for wireless communication, comprising:
- a transceiver;
- a memory configured to store instructions;
- and
- at least one processor communicatively coupled with the transceiver and the memory, wherein the at least one processor is configured to:
- determine a resource block allocation for a single-carrier waveform associated with time domain processing, wherein the resource block allocation is determined based on one of:
- (a) a semi-static assignment of resource blocks via radio resource control (RRC) signaling and varies based on a predetermined pattern received via a network entity indication, or
- (b) receiving a media access control (MAC) control element (CE),
- transmitting an acknowledgment to the network entity in response to receiving the MAC CE;
- and
- utilizing the resource block allocation a period of time after transmission of the acknowledgment to the network entity, or
- (c) receiving an assignment to one or more distinct resource block allocations via downlink control information (DCI), wherein the DCI includes a first stage cross-slot DCI controlling the resource block allocation and a second stage DCI indicating scheduling parameters other than the resource block allocation;
- configure data for transmission or reception according to the single-carrier waveform and based on the determined resource block allocation;
- and
- transmit or receiving the data according to the single-carrier waveform and the determined resource block allocation to a network entity.
