An information receiving method, an information sending method and devices are disclosed. The information receiving method includes: in case that the user equipment is configured with multiple SPS PDSCHs and there are overlaps among multiple SPS PDSCHs on time domain positions in a first slot, determining, according to SPS configuration indexes of the SPS PDSCHs and the time domain positions of the SPS PDSCHs, some SPS PDSCHs whose time domain positions do not overlap, from the multiple SPS PDSCHs in the first slot; and, for the multiple SPS PDSCHs in the first slot, decoding, by the user equipment, only the some SPS PDSCHs of the multiple SPS PDSCHs.

A terminal device receives first information from a network device, where the first information indicates transmission direction information and/or service load information. The terminal device receives downlink control information DCI from the network device based on the first information. The network device may configure a DCI transmission mode by using the first information based on a characteristic of a to-be-transmitted service of the terminal device.

Certain aspects of the present disclosure provide techniques for communicating uplink and downlink transmissions when a semi-statically configured scheduling occasion is overwritten by a slot format indicator. A method performed by a user equipment (UE) includes receiving a control message from a base station (BS) activating a semi-static scheduling configuration, wherein the semi-static scheduling configuration indicates a plurality of configured grant (CG) symbols in which the UE is scheduled to transmit at least one uplink transmission to the BS. The method may further include receiving, from the BS, a slot format indicator (SFI) that overwrites a subset of CG symbols of the plurality of CG symbols to be downlink symbols, and taking one or more actions to communicate at least one downlink transmission in the downlink symbols.

An apparatus includes at least one processor; and at least one non-transitory memory including computer program code; wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to: receive from a network a configuration of two or more uplink grants; transmit uplink data to the network during operating in a given time with one of the two or more uplink grants; and operate with a first operation following receiving an indication of triggering the first operation for the apparatus, or following the apparatus autonomously triggering the first operation; wherein operating with the first operation corresponds to at least using the one of the two or more uplink grants for uplink transmission.

A method for transmitting a HARQ-ACK by a UE is provided. The method receives an SPS configuration. The method then receives a DCI format which activates the SPS configuration and also indicates a first offset for transmitting the HARQ-ACK. After receiving an SPS PDSCH associated with the SPS configuration in a first slot, the method identifies a second slot based on the first slot and the first offset for transmitting the HARQ-ACK. The method determines whether a first PUCCH for transmitting the HARQ-ACK is contained within uplink/flexible symbols of the second slot. When the first PUCCH is not contained within the uplink/flexible symbols and also a parameter that is included in the SPS configuration indicates a deferred HARQ transmission, the method identifies a third slot based on the first slot and a second offset and transmits the HARQ-ACK on a second PUCCH in the third slot.

According to one embodiment of the present disclosure, provided is a method by which a first device performs sidelink communication. The method comprises the steps of: receiving a first DCI including information on a resource for LTE sidelink communication of the first device through a PDCCH from an NR base station; transmitting an SCI to a second device through a PSCCH on the basis of the resource; and transmitting data to the second device through a PSSCH related to the PSCCH, wherein the size of the first DCI can be adjusted from the size of a second DCI to the size of the first DCI, on the basis of the size of the first DCI that is obtained by the NR base station through at least one second DCI different from the first DCI.

This disclosure provides a codebook feedback processing method, a device, an apparatus and a medium. The method includes: determining, by a terminal, based on a quantity of repeated transmissions of a repeatedly transmitted semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), whether there is at least one valid transmission in corresponding transmission opportunities; and determining, by the terminal, based on whether there is at least one valid transmission, whether a feedback bit position is reserved for the SPS PDSCH in a feedback codebook. A base station determines, based on whether there is at least one valid transmission, whether a feedback bit position is reserved for the SPS PDSCH in the feedback codebook.

Certain aspects of the present disclosure provide techniques for collision mitigation in sidelink. A method that may be performed by a user equipment (UE) includes measuring channel busy ratio (CBR), estimating a number of UEs using the channel, estimating a congestion level based on the CBR and the estimated number of UEs. A method that may be performed by a sidelink UE includes determining a semi-persistent scheduling (SPS) resource reservation including first subframes, determining second subframes for generated packet transmission, determining to skip transmission in the second subframes, listening during the second subframes for another sidelink UE’s transmission, and determining whether to reselect resources. Another method includes listening during a first subframe for another sidelink UE’s transmission, detecting the transmission collides with a scheduled transmission resource for the sidelink UE based on an amount of frequency resource overlap, and determining to reselect resources.

This disclosure provides systems, methods, and devices for wireless communication that support managing allocation of configured grant (CG) resources for uplink transmissions using a polynomial over Galois field in a wireless communication system. In particular, a user equipment (UE) may be configured (e.g., by a base station) to determine a resource to access, from a resource pool configured for each CG occasion of a CG configuration, based on a polynomial over Galois field configured for the UE. The polynomial over Galois field may include a parameter p, and the UE may be configured with a mapping that maps the absolute time (e.g., a slot index or a symbol index) of a GC occasion to an index between 0 and p−1 that is used as input to the polynomial The result of the polynomial is used to determine the resource to access by the UE at the CG occasion.

A user device, UE, for a wireless communication network, is to transmit or receive at a plurality of configured or preconfigured opportunities, like a plurality or semi-persistent scheduling, SPS, or configured grant, CG, opportunities; and wherein, responsive to one or more criteria, the UE is to skip one or more of the SPS or CG opportunities.
