Abstract
Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method for wireless communication. The method includes determining at least one RS pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein at least a portion of the at least one RS pattern is the same for the uplink channel and the downlink channel. The method further includes transmitting the reference signal using the determined RS pattern.
Claims26
A method for wireless communication, the method comprising:
- determining at least one reference signal (RS) pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein the at least one RS pattern is the same for the uplink channel and the downlink channel;
- determining a reference signal sequence to use to generate the reference signal for a resource block based on a location of the resource block allocated for the reference signal, wherein the reference signal sequence for the resource block is a sub-sequence of a mother sequence occupying a bandwidth comprising a plurality of resources blocks, and wherein the sub-sequence represents a portion of the mother sequence;
- generating the reference signal utilizing the determined reference signal sequence;
- and
- transmitting the reference signal using the determined RS pattern.
An apparatus for wireless communication comprising:
- a memory;
- and
- a processor configured to:
- determine at least one reference signal (RS) pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein the at least one RS pattern is the same for the uplink channel and the downlink channel;
- determining a reference signal sequence to use to generate the reference signal for a resource block based on a location of the resource block allocated for the reference signal, wherein the reference signal sequence for the resource block is a sub-sequence of a mother sequence occupying a bandwidth comprising a plurality of resources blocks, and wherein the sub-sequence represents a portion of the mother sequence;
- generating the reference signal utilizing the determined reference signal sequence;
- and
- transmit the reference signal using the determined RS pattern.
An apparatus for wireless communication comprising:
- means for determining at least one reference signal (RS) pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein the at least one RS pattern is the same for the uplink channel and the downlink channel;
- means for determining a reference signal sequence to use to generate the reference signal for a resource block based on a location of the resource block allocated for the reference signal, wherein the reference signal sequence for the resource block is a sub-sequence of a mother sequence occupying a bandwidth comprising a plurality of resources blocks, and wherein the sub-sequence represents a portion of the mother sequence;
- means for generating the reference signal utilizing the determined reference signal sequence;
- and
- means for transmitting the reference signal using the determined RS pattern.
A non-transitory computer readable medium having instructions stored thereon for causing at least one processor to perform a method, the method comprising:
- determining at least one reference signal (RS) pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein the at least one RS pattern is the same for the uplink channel and the downlink channel;
- determining a reference signal sequence to use to generate the reference signal for a resource block based on a location of the resource block allocated for the reference signal, wherein the reference signal sequence for the resource block is a sub-sequence of a mother sequence occupying a bandwidth comprising a plurality of resources blocks, and wherein the sub-sequence represents a portion of the mother sequence;
- generating the reference signal utilizing the determined reference signal sequence;
- and
- transmitting the reference signal using the determined RS pattern.
