Abstract:
Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.
Abstract:
Certain aspects of the present disclosure relate generally to wireless communications systems, and more particularly, to improving efficiency of bandwidth part (BWP) switching.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. Numerous other aspects are provided.
Abstract:
Certain aspects of the present disclosure relate to communication systems, and more particularly, to efficient data scheduling in systems having a supplemental uplink carrier (SUL) configured. In some aspects, a method for wireless communications by a user equipment (UE) is provided. The UE receives signaling configuring the UE for uplink control channel transmission on a primary uplink carrier (PUL) or a SUL. The SUL is an uplink carrier not paired to a downlink carrier. The UE monitors in at least one search space for downlink control information (DCI) scheduling the UE for uplink data transmission to a cell on the PUL or the SUL. The UE sends one or more uplink data transmissions to the cell on the primary uplink carrier or the supplemental uplink carrier based on the DCI.
Abstract:
Certain aspects of the present disclosure relate to communication systems, and more particularly, to random access channel (RACH) procedures in deployments where a RACH transmission may be sent on different UL carriers, which may include supplemental UL (SUL) carriers.
Abstract:
Aspects and techniques relate to scheduling resources for uplink transmissions in wireless communication systems. In some examples, an allocation of resources for uplink may be based on a common reference resource (e.g., a reference physical resource block, PRB) also used for allocation of resources for downlink In other examples, allocation of resources for uplink may be based on a different reference resource. A scheduler may further provide an indication whether the same, common reference resource is used, or a different reference resource. A scheduler may further indicate a different reference resource as needed. Other aspects, embodiments, and features are also claimed and described.
Abstract:
Some techniques and apparatuses, described herein, provide for resource allocation to achieve frequency diversity, time diversity, and/or spatial diversity for wakeup signals destined to two or more UE groups by transmitting the wakeup signals according to respective resource patterns associated with the two or more UE groups. Additionally, some techniques and apparatuses described herein provide for resource allocation to achieve spatial diversity for wakeup signals for a single UE group by transmitting the wakeup signals using two or more antenna ports according to respective resource patterns associated with the two or more antenna ports. Furthermore, some techniques and apparatuses described herein provide configurations for wakeup signals based at least in part on delays or gaps, repetitious communications, synchronization in accordance with a power level of the wakeup signal, and the like.
Abstract:
Various aspects described herein relate to hybrid automatic repeat/request (HARQ) communications in a wireless network. A first instance of a HARQ communication is transmitted or received over a first set of one or more links. Based on the transmitting or receiving the first instance of the HARQ communication, a scheduling grant can be received for a second instance of the HARQ communication over a second set of one or more links different from the first set of one or more links. The second instance of the HARQ communication can accordingly be transmitted or received over the second set of one or more links based at least in part on the scheduling grant.
Abstract:
Disclosed are techniques for wireless positioning. In an aspect, a reduced- capability user equipment (UE) receives, from each of one or more premium UEs, one or more parameters indicating a quality of a location estimate of the premium UE, selects at least one premium UE based on the quality of the location estimate of the at least one premium UE, and derives a location estimate of the reduced-capability UE based on the location estimate of the at least one premium UE. In another aspect, a reduced-capability UE transmits, to at least one premium UE, a request to perform one or more positioning measurements of one or more downlink reference signals, receives, from the at least one premium UE, a measurement report comprising the one or more positioning measurements, and determines a location estimate of the reduced-capability UE based on the one or more positioning measurements in the measurement report.
Abstract:
A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE receives downlink control information (DCI) indicating for the UE to skip physical downlink control channel (PDCCH) monitoring or to extend a connected discontinuous reception (CDRX) active time. The DCI includes one or more of a skip indication, scheduling for a retransmission of a successfully decoded physical downlink shared channel (PDSCH), a non-zero downlink assignment with a downlink retransmission transport block (TB) size that is different than an initial downlink transmission TB size, or a non-zero uplink assignment with an uplink retransmission TB size that is different than an initial uplink transmission TB size. The UE further skips transmission of hybrid automatic repeat request (HARQ) feedback for the DCI.
