Abstract:
Methods, apparatuses, and computer-readable mediums for wireless communication include re-coding a first coded packet into a second coded packet, wherein the second coded packet includes less coded bits and has a higher modulation order than the first packet, generating one or more redundant versions of the second packet, and transmitting the second packet and the one or more redundant versions of the second packet at different times to a receiving user equipment.
Abstract:
Methods, apparatuses, and computer-readable mediums for wireless communication by a user equipment (UE) includes transmitting a packet on a first resource, determining one or more repetition resources on which to send one or more redundancy versions of the packet, wherein the one or more repetition resources are at a time subsequent to the first resource, transmitting repetition resource information identifying the one or more repetition resources to one or more neighboring UEs, and transmitting the one or more redundancy versions of the packet on respective ones of the one or more repetition resources.
Abstract:
One or more scheduling grants may be received from a Node B related to a plurality of uplink MIMO streams. A determination may be made as to a primary transport power and a primary transport block size for a primary stream. A secondary transmit power and a secondary transport block size for a secondary stream may also be determined. An enhanced relative grant channel from the Node B, as well as another E-RGC from a non-serving Node B may be received for each of the plurality of uplink MIMO streams.
Abstract:
Methods, systems, and devices for wireless communications are described in which a transmitting user equipment (UE) may determine a data packet to transmit to another UE and determine a set of candidate resources for transmission of the data packet based on a set of time-frequency resources that are allocated for UE-to-UE communications. A resource reservation signal (RRS) may be transmitted to indicate to other UEs that the set of candidate resources have been reserved by a UE. The RRS may be transmitted such that the RRS may be differentiated from other regular transmissions based at least in part on information provided by a control channel associated with the RRS or a payload of a transmission that includes the RRS. The RRS may indicate one or more of a size of an allocation of the resources and multiple locations of the resources within a time-frequency resource pool.
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The apparatus may receive from a second device a first data packet in one or more receiving slots of a time division duplex frame that includes a plurality of slots. The apparatus may determine whether the first data packet is received incorrectly. The apparatus may wait until the end of the one or more receiving slots and may transmit to the second device a first NACK in a NACK feedback symbol in a configured slot after the end of the one or more receiving slots in response to determining that the first data packet was not received correctly.
Abstract:
Aspects of the disclosure relate to methods for wireless communication. A transmitting device transmits a first portion of a control message to a receiving device. The first portion includes information for decoding a second portion of the control message and for decoding data. The transmitting device then transmits the second portion to the receiving device, the second portion including additional information for decoding the data. Thereafter, the first device transmits the data to the receiving device. The receiving device receives the first portion and the second portion, and decodes the received second portion based on the information included in the first portion. The receiving device then receives the data from the second device if the received second portion is able to be decoded. The receiving device decodes the received data based on the information included in the first portion and the additional information included in the second portion.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more sidelink communications on a sidelink between the UE and another UE. The UE may transmit one or more hybrid automatic repeat request (HARQ) feedback communications, associated with the one or more sidelink communications, on the sidelink and in a HARQ feedback resource included in a multi-slot feedback reporting period. The HARQ feedback resource may include a set of negative acknowledgement (NACK) resources or the set of NACK resources and a set of acknowledgement (ACK) resources. Numerous other aspects are provided.
Abstract:
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the apparatus is configured to determine a target receiver power level for uplink transmissions received at the apparatus, to determine uplink power control information based on the determined target receiver power level for UL MU-MIMO transmission or UL OFDMA transmission, and to transmit a frame that includes the determined uplink power control information to a station scheduled by the apparatus for uplink transmission.
Abstract:
Aspects of the present disclosure provide a method for wireless communications by a peer device. The method generates control information to schedule peer-to-peer communication. The control information includes a first portion with a first set of data and a second portion with a second set of data. The method then transmits the first portion of the control information in a first stage using first time and frequency resources. The first portion indicates a control information format of the second portion. The method further transmits the second portion of the control information in a second stage using second time and frequency resources and the indicated control information format.
Abstract:
An improved manner of transmitting and receiving messages in sidelink communication is presented in which a wireless device receives sidelink control information (SCI) that indicates a zone ID associated with a sidelink message. The wireless device determines a location of the wireless device and determines whether to send feedback for the sidelink message based, at least in part, on the zone ID associated with the sidelink message and the location of the wireless device. The feedback may include hybrid automatic repeat request (HARQ) feedback, and the sidelink message may include a groupcast message. The wireless device may further receive an indication of an intended range in the SCI and may determine whether to send the feedback based on a combination of the zone ID and the intended range for the sidelink message.
