A method for selecting resources for a transmission between a first UE and a second UE is disclosed. A set of coordination resources is determined at the first UE. The set of coordination resources includes coordination information which may indicate whether the set of coordination resources are preferred resources and/or non-preferred resources. The set of coordination resources is sent to the second UE, and the second UE takes the coordination information into account in the resource selection for its own transmission. For example, the resource selection by the second UE may be based on both the sensing result of the second UE and the received coordination information from the first UE. Alternatively, there source selection by the second UE may be based exclusively or non-exclusively on the received coordination information from the first UE.

Sidelink resource selection based on user equipment coordination

Methods of allocating resources for Channel State Information, CSI, transmission, comprising the steps of receiving, from a transmitter User Equipment, a request for resources for transmission of a Channel State Information Reference Signal, CSI-RS; determining, in response to receiving the request for transmission of a CSI-RS, a first resource allocation for CSI-RS transmission; determining, in response to receiving the request for transmission of a CSI-RS, a second resource allocation for a CSI report transmission; and transmitting, to the transmitter User Equipment, the first resource allocation and the second resource allocation.

Channel state information acquisition

Methods for transmitting CSI and/or position information between nodes in a network. In particular processes and systems for sidelink groupcast transmissions in a cellular network.

Sidelink communications

Various techniques and processes for transmission of sidelink control information transmission, and in particular feedback transmission are disclosed. Methods and processes for dynamic grant and periodic resource allocations are discussed.

Sidelink scheduling in cellular networks

Methods for the transmission of SCI messages in sidelink communications for the reservation of resources. The modulation and coding scheme of a second stage SCI may be indicated in the first stage SCI.

Sidelink control information design

Methods for pre-emption of transmission resources in sidelink communications in a cellular network. A reservation message for resources which collide with previously-reserved resources serves as a pre-emption indicator.

Pre-emption in sidelink communications

There is provided a method of determining PSSCH feedback resources performed at a UE, wherein the PSSCH feedback (PSFCH) resource has a periodicity N defined as a number of slots. The method comprises counting a number of sub-channels, C, of PSSCH in the period N, wherein each sub-channel, c, is associated with a PSFCH resource; counting a number of PSFCH resources, R, in the period N; indexing the sub-channels, c, based on time; and after indexing the sub-channels, c, based on time, indexing the sub-channels, c, based on frequency.

Feedback resource determination from sidelink shared channel

Methods and systems for management of uplink HARQ processes where fewer than a defined number of repetitions of uplink data are transmitted on configured grant resources. The applied HARQ processes may be varied dependent on the number of repetitions transmitted and dependent on the reception status at the base station.

Uplink HARQ in cellular wireless communication networks

Systems and methods to allow multiplexing of uplink transmissions over configured-grant resources. If a base station allocates configured-grant uplink transmission resources to a further UE the base station transmits an indication of the overlap to relevant UEs. The UEs may apply an explicit HARQ feedback process, or other techniques to manage transmissions such as transmitting a scheduling request with the data.

Uplink multiplexing in cellular wireless communication networks

Methods and techniques for slot format configuration in a Time Domain Duplex system to allow flexible assignment of resources between uplink and downlink, while avoiding Cross Link Interference. As standard slot ordering is provided together with rules to limit modification of slot format between slots such than an estimate of safe regions can be made.

Configuration of time domain multiplexing

Sub-sampled DMRS are utilised in repeated mini-slots for PUSCH transmission. Each sub-sampled DMRS may be multiplex with data in the respective symbol.

RS for PUSCH repetitions

Systems and methods to bundle mini-slots in an OFDM based wireless communication system. Mini-slots are bundled to improve the probability of successful reception by Permitting repeated transmission of a given transport block of data. Mini-slots which are contiguous or non-contiguous in time and/or frequency may be bundled, and mini-slots from different slots may also be bundled.

Slot bundling

A method of enabling sharing of a transmission medium by a first node of a wireless communications network and at least one further node of the network, comprising at the first node, acquiring occupancy of a channel of the transmission medium for a chosen Channel Occupancy Time which is less than or equal to a Maximum Channel Occupancy Time, generating first medium information comprising first node identification data, generating second medium sharing information comprising first node channel occupancy expiration time data, transmitting the first medium sharing information, transmitting the second medium sharing information, at the further node, receiving the first medium sharing information, using the information to identify the first node and using the identification of the first node to determine when sharing of the channel with the first node is allowed, receiving the second medium sharing information, using the information to determine the expiration time of the occupancy of the channel by the first node and using the expiration time to determine when transmission on the channel by the further node is possible.

Transmission medium sharing in a wireless communications network

Methods for allocating resources for uplink grant free data transmission from a UE to a base station. Resources are allocated by the base station and an indication transmitted to the UE, wherein the same resources are available to more than one UE. RRC policies define processes for the selection of resources for initial transmissions and re-transmission following collision.

Methods for the transmission of data in a cellular communications network. Resource sets are configured for a user equipment and subsequent indications may be provided that configured resource sets can be utilised for data transmission. Improved transmission of demodulation reference signals is also provided.
