Abstract
An example method includes receiving a configuration from the wireless communication node. The configuration indicates at least one of one or more numbers of port groups or one or more levels of coherence. The example method further includes determining a precoder for a transmission according to the configuration. The example method further includes performing the transmission using the precoder. In some embodiments, a total number of ports across the port groups is eight.
Claims18
A method for wireless communication, comprising:
- receiving, at a wireless device from a wireless communication node, a configuration that indicates at least one of one or more numbers of port groups for uplink transmissions from the wireless device, wherein a total number of ports is eight;
- determining, at the wireless device, a precoder for an uplink transmission according to the configuration, wherein the precoder is determined from a set of candidate precoders that is reduced by one or more rules that specify a starting port index and a predefined port index order for each candidate precoder in the set;
- and
- performing, at the wireless device, the uplink transmission using the precoder.
A method for wireless communication, comprising:
- transmitting, to a wireless communication device, a configuration that indicates at least one of one or more numbers of port groups for uplink transmissions from the wireless communications device, wherein a total number of ports is eight;
- and
- indicating, to the wireless communication device, a precoder for a transmission according to the configuration, or an indication of number of port groups, wherein the precoder is determined from a set of candidate precoders that is reduced by one or more rules that specify a starting port index and a predefined port index order for each candidate precoder in the set.
An apparatus for wireless communication, comprising a memory and at least one processor, wherein the at least one processor executes instructions stored on the memory to implement a method comprising:
- receiving, from a wireless communication node, a configuration that indicates at least one of one or more numbers of port groups for uplink transmissions, wherein a total number of ports is eight;
- determining a precoder for an uplink transmission according to the configuration, wherein the precoder is determined from a set of candidate precoders that is reduced by one or more rules that specify a starting port index and a predefined port index order for each candidate precoder in the set;
- and
- performing the uplink transmission using the precoder.
An apparatus for wireless communication, comprising a memory and at least one processor, wherein the at least one processor executes instructions stored on the memory to implement a method comprising:
- transmitting, to a wireless communication device, a configuration that indicates at least one of one or more numbers of port groups for uplink transmissions from the wireless communications device, wherein a total number of ports is eight;
- and
- indicating, to the wireless communication device, a precoder for a transmission according to the configuration, or an indication of number of port groups, wherein the precoder is determined from a set of candidate precoders that is reduced by one or more rules that specify a starting port index and a predefined port index order for each candidate precoder in the set.
