BACKGROUND

Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to communicating using multiple transmission points.

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include code-division multiple access (CDMA) systems, time-division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, and orthogonal frequency-division multiple access (OFDMA) systems, and single-carrier frequency division multiple access (SC-FDMA) systems.

These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. For example, a fifth generation (5G) wireless communications technology (which can be referred to as 5G new radio (5G NR)) is envisaged to expand and support diverse usage scenarios and applications with respect to current mobile network generations. In an aspect, 5G communications technology can include: enhanced mobile broadband addressing human-centric use cases for access to multimedia content, services and data; ultra-reliable-low latency communications (URLLC) with certain specifications for latency and reliability; and massive machine type communications, which can allow a very large number of connected devices and transmission of a relatively low volume of non-delay-sensitive information.

SUMMARY

The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.

According to an example, a method of wireless communication is provided. The method includes communicating in a wireless network based on a configured set of one or more transmission points (TRPs), receiving an instruction to modify the set of one or more TRPs, wherein receiving the instruction comprises receiving the instruction to switch a bandwidth part (BWP) used to communicate in the wireless network, wherein the BWP corresponds to modifying the set of one or more TRPs, modifying, based on the instruction to switch the BWP, the set of one or more TRPs to generate a modified set of one or more TRPs, and communicating in the wireless network based on the modified set of one or more TRPs.

In another example, an apparatus for wireless communication is provided including a transceiver, a memory configured to store instructions related to configuring a set of one or more TRPs, and one or more processors communicatively coupled with the transceiver and the memory. The one or more processors are configured to communicate in a wireless network based on a configured set of one or more TRPs, receive an instruction to modify the set of one or more TRPs, wherein receiving the instruction comprises receiving the instruction to switch a BWP used to communicate in the wireless network, wherein the BWP corresponds to modifying the set of one or more TRPs, modify, based on the instruction to switch the BWP, the set of one or more TRPs to generate a modified set of one or more TRPs, and communicate in the wireless network based on the modified set of one or more TRPs.

In another example, an apparatus for wireless communication is provided that includes means for communicating in a wireless network based on a configured set of one or more TRPs, means for receiving an instruction to modify the set of one or more TRPs, wherein receiving the instruction comprises receiving the instruction to switch a BWP used to communicate in the wireless network, wherein the BWP corresponds to modifying the set of one or more TRPs, means for modifying, based on the instruction to switch the BWP, the set of one or more TRPs to generate a modified set of one or more TRPs, and means for communicating in the wireless network based on the modified set of one or more TRPs.

In another example, a computer-readable medium, including code executable by one or more processors for wireless communications is provided. The code includes code for communicating in a wireless network based on a configured set of one or more TRPs, receiving an instruction to modify the set of one or more TRPs, wherein receiving the instruction comprises receiving the instruction to switch a BWP used to communicate in the wireless network, wherein the BWP corresponds to modifying the set of one or more TRPs, modifying, based on the instruction to switch the BWP, the set of one or more TRPs to generate a modified set of one or more TRPs, and communicating in the wireless network based on the modified set of one or more TRPs.

In another example, a method of wireless communication is provided. The method includes configuring a user equipment (UE) with a configured set of one or more TRPs for communicating in a wireless network, and transmitting, to the UE, an instruction to modify the set of one or more TRPs to at least one of activate communications with at least one TRP to the set of one or more TRPs or deactivate communications with at least one TRP from the set of one or more TRPs. Transmitting the instruction includes transmitting the instruction to switch a bandwidth part (BWP) used to communicate in the wireless network, wherein the BWP corresponds to a single TRP or multiple TRPs.

In another example, an apparatus for wireless communication is provided that includes a transceiver, a memory configured to store instructions related to configuring a set of one or more TRPs, and one or more processors communicatively coupled with the transceiver and the memory. The one or more processors are configured to configure a UE with a configured set of one or more TRPs for communicating in a wireless network, and transmit, to the UE, an instruction to modify the set of one or more TRPs to at least one of activate communications with at least one TRP to the set of one or more TRPs or deactivate communications with at least one TRP from the set of one or more TRPs. The one or more processors are configured to transmit the instruction to switch a BWP used to communicate in the wireless network, wherein the BWP corresponds to a single TRP or multiple TRPs.

In another example, an apparatus for wireless communication is provided including means for configuring a UE with a configured set of one or more TRPs for communicating in a wireless network, and means for transmitting, to the UE, an instruction to modify the set of one or more TRPs to at least one of activate communications with at least one TRP to the set of one or more TRPs or deactivate communications with at least one TRP from the set of one or more TRPs. The means for transmitting transmits the instruction to switch a BWP used to communicate in the wireless network, wherein the BWP corresponds to a single TRP or multiple TRPs.

In another example, a computer-readable medium, including code executable by one or more processors for wireless communications is provided. The code includes code for configuring a UE with a configured set of one or more TRPs for communicating in a wireless network, and transmitting, to the UE, an instruction to modify the set of one or more TRPs to at least one of activate communications with at least one TRP to the set of one or more TRPs or deactivate communications with at least one TRP from the set of one or more TRPs. The code for transmitting transmits the instruction to switch a BWP used to communicate in the wireless network, wherein the BWP corresponds to a single TRP or multiple TRPs.

To the accomplishment of the foregoing and related ends, the one or more aspects comprise the features hereinafter fully described and particularly pointed out in the claims. The following description and the annexed drawings set forth in detail certain illustrative features of the one or more aspects. These features are indicative, however, of but a few of the various ways in which the principles of various aspects may be employed, and this description is intended to include all such aspects and their equivalents.
