UPLINK SIGNAL TRANSMISSION METHOD, APPARATUS, SYSTEM, COMMUNICATIONS DEVICE, AND STORAGE MEDIUM

China Mobile Communicatio...

1. A method for transmitting an uplink (UL) signal, applied into a terminal side and comprising:determining, by User Equipment (UE), according to a Listen Before Talk (LBT) result, a starting transmission position for transmission of the UL signal from at least one predefined candidate transmission position; and
starting, by the UE, a transmission of the UL signal at the determined starting transmission position,
wherein the determining, by the UE, according to the LBT result, the starting transmission position for transmission of the UL signal from the at least one predefined candidate transmission position comprises:
for a UL subframe, sequentially sensing, by the UE, whether a channel is idle before each candidate transmission position in the UL subframe from a first candidate transmission position of the UL subframe, until sensing a candidate transmission position when the channel is idle before the candidate transmission position; and
determining the candidate transmission position when the channel is idle before the candidate transmission position as the starting transmission position for transmission of the UL signal; and
wherein, for each candidate transmission position, the determination regarding whether the channel is idle before the candidate transmission position is made according to the following method:
starting detection of at least one of a total power level or a predetermined characteristic signal level on the present channel at a predetermined advance prior to the candidate transmission position;
when the total power level is less than a first predetermined threshold and/or the predetermined characteristic signal level is less than a second predetermined threshold within a predefined duration, determining that the channel is idle before the candidate transmission position; or
when the total power level is not less than the first predetermined threshold and the predetermined characteristic signal level is not less than the second predetermined threshold within the predefined duration, determining that the channel is busy before the candidate transmission.

FRONT-HAUL TRANSPORT NETWORK, DATA TRANSMISSION METHOD, APPARATUS AND COMPUTER STORAGE MEDIUM

CHINA MOBILE COMMUNICATIO...

1. A front-haul transport network (FTN), comprising:an access-type front-haul transport node (FTN-ACC), configured to be connected to a remote radio unit (RRU); and
an aggregation-type front-haul transport node (FTN-AGG), having one end connected to the FTN-ACC and the other end connected to a base band unit (BBU) pool;
wherein at least two types of transmission channels with different transmission delays are established between the FTN-ACC and the FTN-AGG; and at least one of the FTN-ACC or the FTN-AGG is configured to select a corresponding transmission channel for transmission according to a delay requirement of data;
wherein the transmission channel comprises at least two of a direct connection channel, a shared channel or a hybrid channel;
the direct connection channel is a direct transmission channel that uses pre-allocated transmission resources for data transmission between a source node and a sink node; when the source node is the FTN-ACC, the sink node is the FTN-AGG; when the source node is the FTN-AGG, the sink node is the FTN-ACC;
the shared channel is a statistical multiplexing channel that uses dynamically allocated transmission resources for transmission between any two adjacent transmission nodes, wherein the shared channel is a transmission path between two FTN-ACCs, or a transmission path between the FTN-ACC and the FTN-AGG;
the hybrid channel comprises a direct connection path and a shared path, wherein the direct connection path is a path that uses predetermined and pre-allocated transmission resources for transmission between transmission nodes; the shared path is a path that uses dynamically allocated transmission resources for transmission between the transmission nodes; and each of the transmission nodes is the FTN-ACC or the FTN-AGG.
