Problems solved by technology

In this way, when the downlink uses high-speed data packet access, the uplink usually uses uplink high-speed data packet access, and the two are scheduled separately for the same user, resulting in a waste of air interface resources; With the multiple-input multiple-output (MIMO) antenna technology, the number of users supported by the base station cell will also increase, which may exceed more than 400. The processing of multi-cell user scheduling has relatively high resource requirements. If the base station in the existing technology is used The method of independently scheduling users who have services in both uplink and downlink will lead to greater waste of resources

Embodiment Construction

[0065] Since in the Long Term Evolution (LTE) technology, the uplink and downlink use a shared channel, therefore, the scheduling information when the user is scheduled uplink or downlink can be shared, and the scheduling information includes: channel quality indication information, service type, traffic volume And transmission delay, etc. After comprehensive consideration of these information, users are queued with priority and scheduled through the base station in a unified manner to realize joint uplink and downlink scheduling and synchronous scheduling of users.

[0066] The present invention provides a method for joint uplink and downlink scheduling of users, the core of which is: according to the scheduling information of users in the uplink or downlink, respectively, calculate the priority level for the corresponding user when it is scheduled uplink or downlink parameter; when the user has services in both the uplink and downlink, the uplink and downlink joint scheduling...

Abstract

The invention relates to a method for coupling ascending and descending distributions. Wherein, it is characterized in that: based on the distribution information of user at descending or ascending chains, calculating out the priority level parameters for user when in descending or ascending distribution; when there are both services in ascending and descending chains, based on the priority level parameters, coupling the ascending and descending distributions for user. The invention can confirm the service quality and save idle resource.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for uplink scheduling and uplink and downlink joint scheduling for users. Background technique [0002] In the earliest Release99 protocol version of Wideband Code Division Multiple Access (WCDMA) technology, uplink and downlink services are carried based on dedicated channels, and the achievable data transmission rate is 384Kbps. As users' demand for high-speed data transmission rates is getting higher and higher, WCDMA standard-setting organizations have successively launched downlink high-speed data packet access technology and uplink high-speed data packet access technology, which can provide peak rates up to 14.4Mbps and 5.76Mbps respectively , and the spectral efficiency has also been greatly improved. [0003] Among them, the High Speed ​​Downlink Data Packet Access (HSDPA) technology was introduced into the 3GPP Release 5 version in 2002. The main features of the HSDPA...
