Abstract
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for DMRS design for DFT-s-OFDM with increased subcarrier spacing. A UE may receive an assignment to transmit on a set of RBs. The set of RBs may be contiguous within a carrier that includes greater than 110 RBs. The UE may transmit DMRS on each RE of one or more adjacent symbols of the set of RBs.
Claims26
A method of wireless communication of a user equipment (UE), comprising:
- receiving an assignment to transmit on a set of resource blocks (RB s), the set of RB s being contiguous within a carrier including greater than 110 RBs;
- and
- transmitting demodulation reference signals (DMRS) on each resource element (RE) of one or more adjacent symbols of the set of RBs;
- wherein the set of RBs includes x RBs, and a length of a DMRS sequence of the transmitted DMRS is equal to x.
An apparatus for wireless communication of a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive an assignment to transmit on a set of resource blocks (RBs), the set of RBs being contiguous within a carrier including greater than 110 RBs;
- transmit first demodulation reference signals (DMRS) on each resource element (RE) of one or more adjacent symbols of the set of RBs, the first DMRS having a first cyclic shift associated with a first port;
- and
- transmit second DMRS on each RE of the one or more adjacent symbols of the set of RBs, the second DMRS having a second cyclic shift associated with a second port, the second cyclic shift being different than the first cyclic shift, the second port being different than the first port.
An apparatus for wireless communication of a user equipment (UE), comprising:
- means for receiving an assignment to transmit on a set of resource blocks (RBs), the set of RBs being contiguous within a carrier including greater than 110 RBs;
- and
- means for transmitting demodulation reference signals (DMRS) on each resource element (RE) of one or more adjacent symbols of the set of RBs;
- wherein the set of RBs includes x RBs, and a length of a DMRS sequence of the transmitted DMRS is equal to x.
A non-transitory computer-readable medium storing computer executable code, the code when executed by at least one processor causes the at least one processor to:
- receive an assignment to transmit on a set of resource blocks (RBs), the set of RBs being contiguous within a carrier including greater than 110 RBs;
- transmit first demodulation reference signals (DMRS) on each resource element (RE) within a first symbol of one or more adjacent symbols of the set of RBs, the first DMRS being associated with a first DMRS sequence associated with a first port;
- and
- transmit second DMRS on each RE within a second symbol of the one or more adjacent symbols of the set of RBs, the second DMRS being associated with a second DMRS sequence associated with a second port, the second DMRS sequence being different than the first DMRS sequence, the second port being different than the first port.
