Techniques and apparatuses for synchronization, scheduling, bandwidth allocation, and reference signal transmission in a 5th generation network

A method for wireless communication, comprising:

• receiving, by a network device and from a first user equipment (UE), first information identifying a first radio frequency (RF) chain capability of the first UE;
• receiving, by the network device and from a second UE, second information identifying a second RF chain capability of the second UE,
• wherein the first UE and the second UE do not support a bandwidth at a frequency center of a channel associated with the first UE and the second UE, and
• wherein the second RF chain capability is different from the first RF chain capability;
• and
• scheduling, by the network device, communications with regards to the first UE and the second UE based at least in part on the first RF chain capability and the second RF chain capability.

A wireless communication device comprising:

• a memory;
• and
• at least one processor operatively coupled to the memory, the at least one processor configured to:
• transmit, to a base station, radio frequency (RF) chain information identifying a first RF chain capability of the wireless communication device and at least one parameter related to the first RF chain capability;
• receive, from the base station, scheduling information identifying a particular sub-channel of a channel,
• wherein the channel supports communications with the wireless communication device and a different wireless communication device based at least in part on the first RF chain capability and a second RF chain capability of the different wireless communication device,
• wherein the wireless communication device and the different wireless communication device do not support a bandwidth at a frequency center of the channel, and
• wherein the second RF chain capability is different from the first RF chain capability;
• and
• communicate on the particular sub-channel based at least in part on the scheduling information,
• wherein the wireless communication device, when communicating on the particular sub-channel, is to perform a switch from a first bandwidth to a second bandwidth based at least in part on one or more of:
• signaling that indicates that the wireless communication device is to perform the switch to the second bandwidth,
• signaling that indicates that the wireless communication device is to perform the switch at a particular time, or
• receiving, by the wireless communication device, an allocation of the second bandwidth when the wireless communication device is capable of dynamically reconfiguring bandwidth of the wireless communication device.

A network device comprising:

• a memory;
• and
• at least one processor operatively coupled to the memory, the at least one processor configured to:
• identify a channel that supports communications with a plurality of user equipment (UEs),
• wherein at least two UEs, of the plurality of UEs, support different bandwidths on the channel;
• transmit at least two synchronization signals,
• wherein the at least two UEs do not support a bandwidth at a frequency center of the channel, and
• wherein at least one synchronization signal, of the at least two synchronization signals, is transmitted in one or more sub-channels of the channel that are not located at the frequency center of the channel to permit the at least two UEs to receive the at least one synchronization signal;
• receive, from the at least two UEs and based at least in part on transmitting the at least two synchronization signals, first information identifying a first radio frequency (RF) chain capability of a first UE of the at least two UEs, and second information identifying a second RF chain capability of a second UE of the at least two UEs;
• and
• schedule communications with regard to the first UE and the second UE based at least in part on the first RF chain capability and the second RF chain capability,
• wherein the second RF chain capability is different from the first RF chain capability.
