Abstract: Methods and Apparatus are provided for downlink retransmission of Code Block Groups (CBGs) when CBG level ACK and NACK feedback is unreliable. A User Equipment (UE) transmits to a Base Station (BS) feedback indicating an Acknowledgement (ACK) or a Negative Acknowledgement (NACK) corresponding to each of received set of CBGs transmitted by the BS to the UE. The BS receives and decodes the feedback and transmits back to the UE information regarding a result of the decoding. The UE, based on the received information, determines whether the BS correctly received and decoded the ACK/NACK feedback, and in some cases, ACKs and NACKs corresponding to which CBGs were incorrectly decoded by the BS. The UE processes retransmitted CBGs received from the BS based on this determination.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may receive an indication of a traffic type, wherein the indication is received via a first radiofrequency (RF) band. The apparatus may configure the apparatus to switch from a first antenna subarray operation that uses a first set of antenna subarrays to a second antenna subarray operation that uses a second set of antenna subarrays based at least in part on receiving the indication of the traffic type, wherein the second antenna subarray operation uses a second RF band for a communication. The apparatus may transmit the communication using the second antenna subarray operation.

Abstract: The present disclosure may enable a buffer to accommodate HARQ processes for transmissions with different TTIs when the UE is configured for legacy communications and ULL communications. The apparatus may allocate a first number of HARQ IDs to a first portion of a buffer, the first number of HARQ IDs being associated with a first transmission TTI HARQ process. In addition, the apparatus may allocate a second number of HARQ IDs to a second portion of the buffer. In an aspect, the second number of HARQ IDs may be associated with a second TTI HARQ process. In addition, the first portion and second portion may not change a total buffer size. The apparatus may also receive a HARQ response associated with a HARQ ID allocated to the first portion or the second portion.

Abstract: Wireless networks support MU-MIMO transmission in which a base station transmits multiple spatial layers or spatial streams over a shared downlink resource to multiple UEs. However, UEs participating in the MU-MIMO transmission may need to manage interference associated with spatial streams intended for other users. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to provide an MU-MIMO transmission to a plurality of user UEs over a same set of resource blocks. The apparatus may be configured to generate a DCI message for each UE. The DCI message may indicate a DL grant to each UE and include an MU-MIMO assistance information field that provides each UE with interference information to better decode the spatial layers.

Abstract: Techniques for overlapping cluster architecture for coordinated multipoint (CoMP) are provided. According to certain aspects, a method of wireless communication by a transmission point is provided. The method generally includes receiving, from a first base station, a first signal for a first user equipment (UE) to transmit over the air, receiving, from a second base station, a second signal for a second UE to transmit over the air, and combining the first and the second signals from the first and second base stations and transmitting the combined signal to the first and second UE.

Abstract: The present disclosure enables a base station to group UEs based on similar PMIs for a combined transmission. The apparatus may receive a plurality of PMIs from a plurality of UEs. In one aspect, each PMI in the plurality of PMIs may be received from a different UE. The apparatus may also assign each UE of the plurality of UEs to a UE group. In another aspect, each UE group may be associated with a different PMI set in a plurality of PMI sets. The apparatus may further assign a transmission scheme to each UE group. In one configuration, the apparatus may determine one or more preferred spatial layers for each UE (e.g., based on the PMIs) assigned to a UE group, and schedule a combined transmission for the UE group based on the determined one or more spatial layers.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. An eNB transmits pre-grant(s) to a UE(s) for a target resource on a contention-based carrier. In response, the UE(s) perform a CCA/eCCA and, when successful, transmit a preamble to the eNB based on the pre-grant. The eNB detects the preamble(s) and transmits grant confirmation(s) to the UE(s) for which a preamble was detected. The grant confirmation(s) may modify the pre-grant(s). The eNB may overschedule a target resource and based on the received preambles may transmit grant confirmation(s) that instruct a portion of the UEs for which a preamble was received to transmit data on a target resource and may instruct the remaining portion of the UEs for which a preamble was received to cease or modify data transmission.

Abstract: PDCCH/PDSCH multiplexing with PDSCH data rate control is described. An apparatus is configured to receive, from a network node, DL signaling that indicates a MCS update, for a future time period, of a MCS associated with a PDSCH transmission that is multiplexed with a PDCCH transmission that includes information to schedule the PDSCH transmission. The apparatus is configured to demodulate data from the PDSCH transmission, after beginning the future time period, based on the MCS update. Another apparatus is configured to provide, for a UE, DL signaling that indicates a MCS update, for a future time period, of a MCS associated with a PDSCH transmission that is multiplexed with a PDCCH transmission that includes information to schedule the PDSCH transmission. The apparatus is configured to provide, for the UE, modulated data associated with the PDSCH transmission, after beginning the future time period, based on the MCS update.
