Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives an LDCS configuration for a UE relay from a second entity and monitors for an LDCS from the UE relay based on the received LDCS configuration. The second entity may comprise one of an LPN that is not in a dormant state and a Macro cell. The apparatus may receive LDCS configurations for a plurality of LPNs and monitor for a plurality of LPNs based on the received LDCS configurations. When the apparatus determines a need to connect to a LPN, the apparatus may select an LPN among the plurality of LPNs.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus identifies a UE relay and transmits a very low duty cycle signal (LDCS) configuration of the UE relay. The apparatus may comprise, e.g., an LPN that is not in a dormant state or a macrocell. The apparatus may receive LDCS information for the UE relay. The apparatus may determine the LDCS configuration and transmit the LDCS configuration to the UE relay.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus transitions to a dormant state and transmits a very low duty cycle signal (LDCS) while in the dormant state. The apparatus may transmit an LDCS configuration to a second entity, the second entity being one of an LPN that is not in a dormant state and a macro cell. The apparatus may further monitor for a RACH messages at a predetermined RACH delay after transmitting the LDCS. The apparatus may transition to a DRX/DTX mode. The DRX/DTX mode may be matched to at least one connected UE.
Abstract:
Time tracking in current communication systems may be traditionally based on common reference signals (CRS). However, in certain communication systems, CRS-based time tracking may be impossible to implement due to an absence of CRS in certain subframes or carriers. CRS-based time tracking may also be inappropriate to implement in certain communication systems such as a coordinated multipoint (CoMP) system where control and data may arrive from different cells, and therefore, a UE may assume a wrong cell for CRS-based time tracking. Accordingly, methods, apparatuses, and computer program products for wireless communication are provided in which additional UE specific reference signals (UE-RS) and/or channel state information reference signals (CSI-RS) are made available to the UE so that the UE may have improved channel estimation and/or time tracking performance.
Abstract:
A method, a computer program product, and an apparatus for determining retransmission feedback resources are provided. An apparatus receives a downlink resource assignment over a control channel and obtains an offset related to a region for retransmission feedback resources. The offset is determined based on a type of the control channel. The apparatus determines resources for communicating retransmission feedback for communications received over the downlink resource assignment based on an index of a resource related to the downlink resource assignment and the offset. The apparatus transmits retransmission feedback for the communications over the resources.
Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus of a first cell communicates with a second cell in relation to a coordinated multipoint (CoMP) transmission of control information by the second cell and data by the first cell to a user equipment (UE) in a range expanded region of the first cell, determines a desired transmission power level for an uplink transmission to the first cell by the UE, and provides the desired transmission power level for the uplink transmission to the second cell.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a response message associated with a random access message, wherein the response message includes an identifier of the UE; select a format of an uplink channel or an uplink signal for acknowledging successful decoding of the response message; determine a transmit power for hybrid automatic repeat request (HARQ) acknowledgment (ACK) information based at least in part on at least one of: a message type of the response message, a mode of random access associated with the random access message, a power control configuration used by a previous transmission of the random access message, or the format of the uplink channel or the uplink signal; and transmit the HARQ ACK information using a power control procedure based at least in part on the transmit power. Numerous other aspects are provided.
Abstract:
Methods, systems, and devices for wireless communications are described. A network entity may transmit a set of synchronization signal blocks (SSBs) to a user equipment (UE). The set of SSBs may indicate both a first set of random access occasions and a second set of random access occasions that may be different than the first set of random access occasions. The second set of random access occasions may be associated with full-duplex capable wireless devices (e.g., UEs). As such, the network entity may monitor both the first set of random access occasions and the second set of random access occasions. Based on the monitoring, the network entity may receive a random access preamble from a UE during a random access occasion. The UE may transmit the random access preamble during the random access occasion based on the UE being a full-duplex capable wireless device.
Abstract:
Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.
Abstract:
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for DCI content and modified/enhanced codebook Type 3 HARQ PUCCH content for deferred SPS PUCCH ACK/NACK. In aspects, a UE may receive, from a base station, DCI including a request for HARQ-ACK feedback associated with at least one resource that is unavailable. The HARQ-ACK feedback may be based on one or more one-shot HARQ-ACK codebooks including one or more bits. The UE may transmit, to the base station, the HARQ-ACK feedback associated with the at least one resource that is unavailable, where the HARQ-ACK feedback includes the one or more one-shot HARQ-ACK codebooks including the one or more bits.
