摘要： Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for search space configuration for multicast traffic. According to embodiments of the present disclosure, a first device determines, from a group of search space sets configured to the first device, at least one search space set for monitoring multicast traffic from a second device, based on at least one of a priority of the multicast traffic and respective types of the search space sets. The first device monitors the multicast traffic from the second device in the at least one search space set. The solution enables multicast traffic to be monitored in a common search space set, a user-specific search space set or a multicast search space set in different scenarios.

摘要： Embodiments of the present disclosure relate to downlink control and data channel configuration. A method comprises: determining, at a first device, a transmission scheme of control information for a second device based on at least one multicast and broadcast service related criterion, the control information related to scheduling multicast service traffic to the second device; transmitting, to the second device, configuration information for causing the second device to obtain the control information; and transmitting, to the second device and based on the determined transmission scheme, the control information on a control channel between the first device and the second device. In this way, the correlation between the scheduling mechanism of multicast traffic on the downlink data channel and the transmission mechanism of control information on the downlink control channel can be decoupled, resulting in a flexible and dynamic downlink channel configuration and an increased radio resource efficiency.

摘要： This document discloses a solution for performing spectrum allocations. According to an aspect, there is provided a method comprising: performing, by a spectrum sharing adaptation system, allocation and transmission authorization of a shared spectrum resource to a network element of a communication network, wherein the shared spectrum resource is on frequencies not exclusively licensed to the communication network, and wherein the spectrum sharing adaptation system allocates the shared spectrum resource to the network element by using a first spectrum sharing protocol; acquiring, by the spectrum sharing adaptation system, allocation and transmission authorization of the shared spectrum resource from a spectrum resource manager managing utilization of spectrum resources, wherein the spectrum sharing adaptation system acquires the allocation of the shared spectrum resource by using a second spectrum sharing protocol different from the first spectrum sharing protocol; and performing, by the spectrum sharing adaptation system, adaptation between the first spectrum sharing protocol and the second spectrum sharing protocol.

摘要： A system comprising: a plurality of base stations forming a multicast broadcast single frequency network operating using unlicensed frequency resources; and a network element configured to allocate a transmission period to each of the plurality of base stations, wherein each base station is configured to independently determine whether the unlicensed frequency resources are available for transmission, and transmit a data packet using the unlicensed frequency resources during the allocated transmission period only if the unlicensed frequency resources are determined to be available.

摘要： Example embodiments of the present disclosure relate to polling a device for multicast broadcast service interest indication. A first device receives, from a second device, a physical downlink control channel (PDCCH) order addressed by a paging radio network temporary identifier for the first device. The PDCCH order comprises a request for an indication that at least one multicast broadcast service is to be received by the first device. The first device transmits, to the second device, a random access preamble associated with the at least one multicast broadcast service as a response to the request. Through this solution, the first device that monitors the single PDCCH order may have less power consumption.
