Description	L'invention concerne des systèmes et des procédés de communication sans fil associés à des dispositifs d'équipement utilisateur (UE) de desserte utilisant des techniques de points de réception/multi-transmission (TRP) avec des groupes de TRP à variation dynamique. Un dispositif de communication sans fil reçoit, d'un premier groupe d'un ou plusieurs TRP, un premier signal pendant une première période de temps. Le dispositif de communication sans fil reçoit, d'un second groupe d'un ou plusieurs TRP, un second signal pendant une seconde période de temps, au moins un TRP dans le second groupe n'étant pas dans le premier groupe. Le premier signal peut comprendre un premier bloc de transport (TB) et le second signal peut comprendre un second TB différent du premier TB. En variante, le premier signal peut comprendre une première partie d'un TB et le second signal comprend une seconde partie de la TB différente de la première partie.
Abstract	Wireless communications systems and methods related to serving user equipment devices (UEs) using multi-transmission/reception point (TRP) techniques with dynamic varying TRP clusters are provided. A wireless communication device receives, from a first group of one or more TRPs, a first signal during a first time period. The wireless communication device receives, from a second group of one or more TRPs, a second signal during a second time period, wherein at least one TRP in the second group is not in the first group. The first signal may include a first transport block (TB) and the second signal may include a second TB different from the first TB. Alternatively, the first signal may include a first portion of a TB and the second signal includes a second portion of the TB different from the first portion.

The method of claim 1, wherein the first group includes a different number of TRPs than the second group. The method of claim 1, wherein the first group and the second group include a same number of TRPs. The method of claim 1, wherein the first time period and the second time period are different time periods. The method of claim 4, wherein the first signal includes a first transport block (TB), and wherein the second signal includes a second TB different from the first TB. The method of claim 4, wherein the first signal includes a first portion of a transport block (TB), and wherein the second signal includes a second portion of the TB different from the first portion. The method of claim 6, further comprising: receiving, by the wireless communication device from at least one TRP in the first group, a scheduling grant indicating at least one of: a first modulation and coding scheme (MCS) for the first portion of the TB and a second MCS for the second portion of the TB; a duration of the first time period and a duration of the second time period; a reference signal in the first signal and a reference signal in the second signal; or whether a channel parameter of the reference signal in the first signal is associated with a channel parameter of the reference signal in the second signa The method of claim 6, wherein the first portion of the TB is associated with a first code block group (CBG), wherein the second portion of the TB is associated with a second CBG different from the first CBG, and wherein the method further comprises: transmitting, by the wireless communication device, a feedback for the first CBG; and transmitting, by the wireless communication device, a feedback for the second CBG. determining, by a network unit, a first time period for a first group of one or more transmission/reception points (TRPs) to transmit a first signal to a wireless communication device; determining, by the network unit, a second time period for a second group of one or more TRPs to transmit a second signal to the wireless communication device, wherein at least one TRP in the second group is not in the first group; and transmitting, by the network unit to the wireless communication device via at least a first TRP associated with the network unit in the first group, the first signal during the first time period. The method of claim 9, wherein the first group includes a different number of TRPs than the second group. The method of claim 9, wherein the first group and the second group include a same number of TRPs. The method of claim 9, wherein the first time period and the second time period are different time periods. The method of claim 12, wherein the first signal includes a first transport block (TB), and wherein the second signal includes a second TB different from the first TB. The method of claim 9, wherein the first signal includes a first portion of a transport block (TB), and wherein the second signal includes a second portion of the TB different from the first portion. The method of claim 14, further comprising: transmitting, by the network unit to the wireless communication device via at least the first TRP, a scheduling grant indicating: timing information associated with the first time period and the second time period; a reference signal in the first signal and a reference signal in the second signal; or whether a channel parameter of the reference signal in the first signal is associated with a channel parameter of the reference signal in the second signa The method of claim 14, wherein the first portion of the TB is associated with a first code block group (CBG), wherein the second portion of the TB is associated with a second CBG different from the first CBG, and wherein the method further comprises receiving, by the network unit, a feedback for the first CBG; and receiving, by the network unit, a feedback for the second CBG.
